背景技术Background Art
水泵是用于输送液体或使液体增压的机械，它将原动机的机械能或其他外部能量传送给液体，使液体能量增加，主要用来输送液体包括水、油、酸碱液、乳化液、悬乳液和液态金属等。A water pump is a machine used to transport liquids or increase the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals.
在冶金过程、化工生产和电镀作业时常会用到水泵，利用水泵将工作时产生的热废水流体介质排出。而水泵在对热废水流体介质抽送时，受制于热废水流体介质的较高温度，较高的水温极易导致水的饱和蒸汽压力较大，使得泵进口处的压力低于水的饱和蒸汽压力，由于水泵进口处的压力低于水的饱和蒸汽压力，导致水汽化形成气泡，这些气泡在高压区迅速破裂，对水泵产生冲击，造成损坏，从而造成气蚀现象。Water pumps are often used in metallurgical processes, chemical production and electroplating operations to discharge the hot wastewater fluid medium generated during operation. When pumping hot wastewater fluid medium, the water pump is subject to the high temperature of the hot wastewater fluid medium. The high water temperature easily leads to a high saturated vapor pressure of water, making the pressure at the pump inlet lower than the saturated vapor pressure of water. Since the pressure at the pump inlet is lower than the saturated vapor pressure of water, water vaporizes to form bubbles, which quickly burst in the high-pressure area, impacting the water pump, causing damage, and thus causing cavitation.
而受制于厂区生产的实际工作情况以及经济效益问题，泵体可能需要对不同温度的热废水流体介质进行抽送，不同温度的流体介质抽送过程中，会导致产生气蚀现象频率较多，致使水泵叶轮易损坏，需要经常更换维修。However, due to the actual working conditions of the factory production and economic benefits, the pump body may need to pump hot wastewater fluid media at different temperatures. During the pumping process of fluid media at different temperatures, cavitation will occur more frequently, making the pump impeller easy to be damaged and requiring frequent replacement and maintenance.
为此，本发明提供一种工业用高效过滤循环水泵。To this end, the present invention provides an industrial high-efficiency filtering circulating water pump.

本发明的有益效果如下：The beneficial effects of the present invention are as follows:
1.本发明所述的一种工业用高效过滤循环水泵，通过让制冷片散发出的冷气在连接管内弥漫，导流块通过铁片和制冷片相连，所以制冷片在散发冷气时，冷气会通过铁片快速传递到导流块表面，使得导流块的表面具备低温的效果。泵壳中的叶轮开始工作将工业热废水吸入连接管内，热水进入连接管内后会先被预冷的连接管进行降温，当接触到导流块时会再次被降温，同时三角形的导流块对水进行导流，部分水通过导流槽穿过导流块，而另一部分的水则通过导流块的两侧和圆角穿过，并在两个导流块之间形成回流，从而再次延长水在连接管内的停留时长，方便对热水进行冷却，由于热水穿过连接管和导流块之间时，两者之间间隙小所以会让水流加速，从而水穿过连接管的总时长不变，还能起到降温的效果。再通过端盖的设计减小压力，进而大大降低了叶轮的气蚀现象，使得水泵可以长时间高效的运作。1. The industrial high-efficiency filtering circulating water pump described in the present invention allows the cold air emitted by the refrigeration plate to diffuse in the connecting pipe. The guide block is connected to the refrigeration plate through the iron plate. Therefore, when the refrigeration plate emits cold air, the cold air will be quickly transferred to the surface of the guide block through the iron plate, so that the surface of the guide block has a low temperature effect. The impeller in the pump housing starts to work and sucks the industrial hot wastewater into the connecting pipe. After the hot water enters the connecting pipe, it will be cooled by the pre-cooled connecting pipe first, and will be cooled again when it contacts the guide block. At the same time, the triangular guide block guides the water. Part of the water passes through the guide block through the guide groove, while the other part of the water passes through the two sides and fillet of the guide block, and forms a reflux between the two guide blocks, thereby extending the residence time of the water in the connecting pipe again, which is convenient for cooling the hot water. Since the gap between the connecting pipe and the guide block is small when the hot water passes through the connecting pipe, the water flow will be accelerated, so that the total time for the water to pass through the connecting pipe remains unchanged, and it can also have a cooling effect. The pressure is reduced by the design of the end cover, which greatly reduces the cavitation phenomenon of the impeller, allowing the water pump to operate efficiently for a long time.
2.本发明所述的一种工业用高效过滤循环水泵，通过顶板和回流板向远离回流槽的方向移动，回流板会通过弹性绳带着端盖打开，从而让被盖板挡住的部分水流通过弧形的凸板和回流板被导入回流槽内进行回流冷却，同时由于连接管为金属材质制成的，所以当远离制冷片和导流块的热水进入到回流槽内后，可以更加高效的对热水进行降温。2. The industrial high-efficiency filtering circulating water pump described in the present invention moves in the direction away from the reflux groove through the top plate and the reflux plate, and the reflux plate will open with the end cover through the elastic rope, so that part of the water flow blocked by the cover plate can be introduced into the reflux groove through the arc-shaped convex plate and the reflux plate for reflux cooling. At the same time, since the connecting pipe is made of metal, when the hot water away from the refrigeration plate and the guide block enters the reflux groove, the hot water can be cooled more efficiently.

具体的，盖板14通过推动组件17控制导流块16的移动，推动组件17包括固定安装在盖板14一端的推杆171，以及固定安装在连接杆15上的固定杆172，推杆171和固定杆172均呈弧形，导流块16的表面开设有导流组件18，导流组件18包括开设在导流块16上且贯穿自身的导流槽181，导流块16的端部开设有圆角182，盖板14靠近制冷片13的一面转动连接有橡胶材质的滚轮50，制冷片13的一侧安装有和导流块16相连的铁片60。所述连接管3内设置有辅助机构40，所述辅助机构40包括通过转轴42在连接管3内转动连接的换热管41，所述转轴42通过扭簧和连接管3转动连接，所述转轴42的表面缠绕有防滑绳43，所述防滑绳43的另一端和连接杆15固定连接。Specifically, the cover plate 14 controls the movement of the guide block 16 through the pushing assembly 17. The pushing assembly 17 includes a push rod 171 fixedly installed at one end of the cover plate 14, and a fixed rod 172 fixedly installed on the connecting rod 15. The push rod 171 and the fixed rod 172 are both arc-shaped. A guide assembly 18 is provided on the surface of the guide block 16. The guide assembly 18 includes a guide groove 181 provided on the guide block 16 and passing through the guide block 16. A rounded corner 182 is provided at the end of the guide block 16. A rubber roller 50 is rotatably connected to one side of the cover plate 14 close to the refrigeration plate 13, and an iron sheet 60 connected to the guide block 16 is installed on one side of the refrigeration plate 13. An auxiliary mechanism 40 is provided in the connecting pipe 3, and the auxiliary mechanism 40 includes a heat exchange tube 41 rotatably connected in the connecting pipe 3 via a rotating shaft 42. The rotating shaft 42 is rotatably connected to the connecting pipe 3 via a torsion spring.

工作时，现有的水泵在工作时都会安装过滤机构，用于防止堵塞，从而提高水泵的工作效率。而水泵在抽取工业废水时，更需要考虑其叶轮的使用寿命，从而提高工作效率。当水泵在抽取工业热废水时，提前启动矩形框11内的电动伸缩杆12，让电动伸缩杆12推动制冷片13向连接管3内移动，制冷片13的底部和橡胶材质的滚轮50接触，滚轮50起到辅助打开盖板14的作用，并推动盖板14向连接管3内转动，从而打开连接管3内的方槽，使得制冷片13的制冷面裸露在连接管3内。随着制冷片13的本体的温度不断降低，从而对其周围的空气起到吸热制冷降温的效果，从而逐渐在连接管3内部形成冷气，直至冷气在连接管3内弥漫，进而达到对连接管3内部快速预降温的作用，同时盖板14在打开时会带着推杆171和导流块16接触，让导流块16在连接杆15的作用下向连接管3中心处移动，连接杆15在移动时会通过固定杆172带着下一个导流块16一起移动，使得若干个导流块16均处于连接管3的中心处，同时导流块16通过铁片60（铁片60的正下方为空心的，所以其跟随制冷片13进行移动时不会受阻碍）和制冷片13相连，所以制冷片13在散发冷气时，冷气会通过铁片60快速传递到导流块16表面，使得导流块16的表面具备低温的效果。根据实际使用情况，制冷片13与矩形框11之间为滑动密封连接，同时为了散热，矩形框11上开设有散热孔，或其内部设置有散热机构。When working, existing water pumps are equipped with a filtering mechanism to prevent clogging, thereby improving the working efficiency of the water pump. When the water pump is extracting industrial wastewater, it is more necessary to consider the service life of its impeller to improve the working efficiency. When the water pump is extracting industrial hot wastewater, the electric telescopic rod 12 in the rectangular frame 11 is started in advance, and the electric telescopic rod 12 pushes the refrigeration plate 13 to move into the connecting pipe 3. The bottom of the refrigeration plate 13 contacts the rubber roller 50, and the roller 50 plays a role in assisting the opening of the cover plate 14, and pushes the cover plate 14 to rotate into the connecting pipe 3, thereby opening the square groove in the connecting pipe 3, so that the refrigeration surface of the refrigeration plate 13 is exposed in the connecting pipe 3. As the temperature of the refrigeration plate 13 body continues to decrease, it absorbs heat and cools the air around it, thereby gradually forming cold air inside the connecting pipe 3 until the cold air permeates the connecting pipe 3, thereby achieving the effect of quickly pre-cooling the inside of the connecting pipe 3. At the same time, when the cover plate 14 is opened, it will bring the push rod 171 into contact with the guide block 16, allowing the guide block 16 to move toward the center of the connecting pipe 3 under the action of the connecting rod 15. When the connecting rod 15 moves, it will move with the next guide block 16 through the fixed rod 172, so that several guide blocks 16 are all in the center of the connecting pipe 3. At the same time, the guide block 16 is connected to the refrigeration plate 13 through the iron sheet 60 (the iron sheet 60 is hollow directly below, so it will not be hindered when moving with the refrigeration plate 13). Therefore, when the refrigeration plate 13 emits cold air, the cold air will be quickly transferred to the surface of the guide block 16 through the iron sheet 60, so that the surface of the guide block 16 has a low temperature effect. According to actual use, the cooling fins 13 and the rectangular frame 11 are connected in a sliding and sealing manner. To dissipate heat, the rectangular frame 11 is provided with heat dissipation holes, or a heat dissipation mechanism is provided inside the rectangular frame 11.
同时连接杆15在移动时会带着防滑绳43一起移动，从而带着转轴42进行转动，转轴42会带着换热管41进行转动90°，使得换热管41和水接触的面积变大，从而提高降温效果，当连接杆15复位时，转轴42带着换热管41跟随复位，从而减少对水流通过的影响。需要说明的是，在预先开始工作时，换热换41的进水端和出水端均与外界的容器相连通，且容器中具有换热介质（可以选用水或其他低温流体介质），且通过外部循环泵的使用，使得换热管41内部整体的冷换热介质处于循环流通的状态，当电机1驱动水泵开始工作，使得泵壳2中的叶轮开始工作将工业热废水吸入连接管3内，热水进入连接管3内后会先被预冷的连接管3进行降温，当接触到导流块16时会再次被降温，同时三角形的导流块16对水进行导流，部分水通过导流槽181穿过导流块16，而另一部分的水则通过导流块16的两侧和圆角182穿过，并在两个导流块16之间形成回流，从而再次延长水在连接管3内的停留时长，方便对热水进行冷却，由于热水穿过连接管3和导流块16之间时，两者之间间隙小所以会让水流加速，从而水穿过连接管3的总时长不变，还能起到降温的效果。当水流过导流块16后会制冷片13接触进行再次降温，并通过端盖34上的通槽19流向泵壳2内被抽走，通过上述设计的制冷片13和端盖34设计，能够对热水进行降温处理，从而减少因为水温越高，饱和蒸汽压力越高，导致水泵进口处的压力就越容易低于水的饱和蒸汽压力，从而导致气蚀的产生，再通过端盖34的设计减小压力，进而大大降低了叶轮的气蚀现象，使得水泵可以长时间高效的运作。需要说明的是，可外部容器中的冷介质的量，根据带抽取的废水而决定的，具体可在容器中设置温度感应器，当外部容器中冷介质的温度明显提高时，此时热交换效率大大降低，可以选择更换新的容器以及待换热的冷介质。At the same time, when the connecting rod 15 moves, it will move with the anti-slip rope 43, thereby rotating the rotating shaft 42, and the rotating shaft 42 will rotate the heat exchange tube 41 90°, so that the contact area between the heat exchange tube 41 and the water becomes larger, thereby improving the cooling effect. When the connecting rod 15 is reset, the rotating shaft 42 will follow the reset with the heat exchange tube 41, thereby reducing the impact on the water flow. It should be noted that when the work is started in advance, the water inlet and outlet ends of the heat exchanger 41 are connected to the external container, and the container has a heat exchange medium (water or other low-temperature fluid medium can be selected), and through the use of an external circulation pump, the entire cold heat exchange medium inside the heat exchange tube 41 is in a circulating state. When the motor 1 drives the water pump to start working, the impeller in the pump casing 2 starts to work to suck the industrial hot wastewater into the connecting pipe 3. After the hot water enters the connecting pipe 3, it will first be cooled by the pre-cooled connecting pipe 3. When it contacts the guide block 1 6, it will be cooled again, and at the same time, the triangular guide block 16 guides the water, part of the water passes through the guide block 16 through the guide groove 181, and the other part of the water passes through the two sides and the fillet 182 of the guide block 16, and forms a backflow between the two guide blocks 16, thereby extending the residence time of the water in the connecting pipe 3 again, which is convenient for cooling the hot water. When the hot water passes through the connecting pipe 3 and the guide block 16, the gap between the two is small, so the water flow is accelerated, so that the total time for the water to pass through the connecting pipe 3 remains unchanged, and it can also have a cooling effect. After the water flows through the guide block 16, it will contact the cooling plate 13 to cool down again, and flow into the pump housing 2 through the through groove 19 on the end cover 34 to be pumped away. The cooling plate 13 and the end cover 34 designed as above can cool the hot water, thereby reducing the pressure at the pump inlet being more likely to be lower than the saturated vapor pressure of water because the higher the water temperature, the higher the saturated vapor pressure, which leads to the generation of cavitation. The pressure is then reduced by the design of the end cover 34, thereby greatly reducing the cavitation phenomenon of the impeller, so that the water pump can operate efficiently for a long time. It should be noted that the amount of cold medium in the external container is determined according to the wastewater to be extracted. Specifically, a temperature sensor can be set in the container. When the temperature of the cold medium in the external container is significantly increased, the heat exchange efficiency is greatly reduced. You can choose to replace a new container and the cold medium to be exchanged.
当抽取的工业废水介质为常温状态时，热冷机构可以不启动，管内的换热换41的截面与管体截面处于平行状态，连接管3内部一切正常运行（此时受温度的影响，泵体内部几乎不产生气蚀情况），受实际使用条件，当抽取的是中高温废水介质时，与上述同理，制冷机构预先启动，同时换热管41与管体成垂直状态，抽入的中高温废水介质进入连接管3内部时，与换热管41的接触面积最大，伴随着换热管41内部冷介质的循环流通，使得持续抽取的中高温废水介质，与换热管41内部的冷介质进行热量交换，配合盖板14、两个导流块16的使用使得中高温废水在连接管3内部的流通时间或滞留时间，从而与换热管4的作用形成进一步的交互促进，以便换热管4对中高温废水进行热交换的时间，以达到迅速降低抽送废水的温度，从而尽可能的避免后续因废水温度的问题而导致发生的气蚀现象。When the extracted industrial wastewater medium is at room temperature, the heating and cooling mechanism can be disabled, the cross section of the heat exchange tube 41 in the tube is parallel to the cross section of the tube body, and everything inside the connecting tube 3 operates normally (at this time, affected by the temperature, there is almost no cavitation inside the pump body). Under actual use conditions, when the extracted medium- and high-temperature wastewater medium is at room temperature, the refrigeration mechanism is started in advance, and the heat exchange tube 41 is vertical to the tube body. When the medium- and high-temperature wastewater medium is drawn into the connecting tube 3, the contact area with the heat exchange tube 41 is the largest, accompanied by The circulation of the cold medium inside the heat exchange tube 41 allows the continuously extracted medium- and high-temperature wastewater medium to exchange heat with the cold medium inside the heat exchange tube 41. The use of the cover plate 14 and the two guide blocks 16 increases the circulation time or retention time of the medium- and high-temperature wastewater inside the connecting tube 3, thereby further interacting and promoting the action of the heat exchange tube 4, so that the heat exchange tube 4 can exchange heat with the medium- and high-temperature wastewater for a short time, so as to quickly reduce the temperature of the pumped wastewater, thereby avoiding cavitation caused by subsequent wastewater temperature problems as much as possible.
当水泵抽的冷水时，则不需要电动伸缩杆12带动制冷片13进行工作，此时各零部件处于初始位置，从而减少对水流通过连接管3的影响，便于正常抽取水。When the water pump pumps cold water, the electric telescopic rod 12 is not needed to drive the refrigeration plate 13 to work. At this time, all components are in the initial position, thereby reducing the impact on the water flow through the connecting pipe 3, facilitating normal water extraction.
连接管3的内部设置有辅助水体进行流动的回流机构30，回流机构30包括开设在连接管3内的弧形回流槽31，回流槽31的内部通过弹簧滑动连接有回流板32，回流板32的顶部固定安装有凸板33，盖板14的底部固定安装有顶板36，回流槽31的端口处安装有密封组件。A reflux mechanism 30 for assisting the flow of water is provided inside the connecting pipe 3. The reflux mechanism 30 includes an arc-shaped reflux groove 31 opened in the connecting pipe 3. A reflux plate 32 is slidably connected to the inside of the reflux groove 31 through a spring. A convex plate 33 is fixedly installed on the top of the reflux plate 32. A top plate 36 is fixedly installed on the bottom of the cover plate 14. A sealing assembly is installed at the port of the reflux groove 31.
具体的，密封组件包括两个通过扭簧转动连接的端盖34，端盖34和回流板32之间固定安装有连接绳35。Specifically, the sealing assembly includes two end covers 34 rotatably connected by a torsion spring, and a connecting rope 35 is fixedly installed between the end cover 34 and the return plate 32 .
工作时，当盖板14打开时会通过一侧的顶板36与回流板32上的凸板33接触，并带动顶板36和回流板32向远离回流槽31的方向移动，回流板32会通过弹性绳带着端盖34打开，从而让被盖板14挡住的部分水流通过弧形的凸板33和回流板32被导入回流槽31内进行回流冷却，同时由于连接管3为金属材质制成的，所以当远离制冷片13和导流块16的热水进入到回流槽31内后，可以更加高效的对热水进行降温。During operation, when the cover plate 14 is opened, the top plate 36 on one side will contact the convex plate 33 on the return plate 32, and drive the top plate 36 and the return plate 32 to move away from the return groove 31. The return plate 32 will open with the end cover 34 through the elastic rope, so that part of the water flow blocked by the cover plate 14 can be introduced into the return groove 31 through the arc-shaped convex plate 33 and the return plate 32 for reflux cooling. At the same time, since the connecting pipe 3 is made of metal, when the hot water away from the refrigeration plate 13 and the guide block 16 enters the return groove 31, the hot water can be cooled more efficiently.
导热机构20包括固定安装在电动伸缩杆12输出端上的空心推板21，推板21将制冷片13罩住，推板21的一侧固定安装有和内部相连通的导热管22，推板21的侧壁固定安装有橡胶材质的密封垫23。The heat conduction mechanism 20 includes a hollow push plate 21 fixedly mounted on the output end of the electric telescopic rod 12. The push plate 21 covers the refrigeration plate 13. A heat conduction pipe 22 connected to the interior is fixedly mounted on one side of the push plate 21. A rubber sealing pad 23 is fixedly mounted on the side wall of the push plate 21.
工作原理：当水泵在抽取工业热废水时，提前启动矩形框11内的电动伸缩杆12，让电动伸缩杆12推动制冷片13向连接管3内移动，制冷片13的底部和橡胶材质的滚轮50接触，滚轮50起到辅助打开盖板14的作用，并推动盖板14向连接管3内转动，从而打开连接管3内的方槽，使得制冷片13的制冷面裸露在连接管3内。随着制冷片13散发出的冷气在连接管3内弥漫，同时盖板14在打开时会带着推杆171和导流块16接触，让导流块16在连接杆15的作用下向连接管3中心处移动，连接杆15在移动时会通过固定杆172带着下一个导流块16一起移动，使得若干个导流块16均处于连接管3的中心处，同时导流块16通过铁片60和制冷片13相连，所以制冷片13在散发冷气时，冷气会通过铁片60快速传递到导流块16表面。Working principle: When the water pump is extracting industrial hot wastewater, the electric telescopic rod 12 in the rectangular frame 11 is started in advance, and the electric telescopic rod 12 pushes the refrigeration plate 13 to move into the connecting pipe 3. The bottom of the refrigeration plate 13 contacts the rubber roller 50. The roller 50 assists in opening the cover 14 and pushes the cover 14 to rotate into the connecting pipe 3, thereby opening the square groove in the connecting pipe 3, so that the cooling surface of the refrigeration plate 13 is exposed in the connecting pipe 3. As the cold air emitted by the refrigeration plate 13 diffuses in the connecting pipe 3, the cover plate 14 will bring the push rod 171 into contact with the guide block 16 when it is opened, allowing the guide block 16 to move toward the center of the connecting pipe 3 under the action of the connecting rod 15. When the connecting rod 15 moves, it will move with the next guide block 16 through the fixed rod 172, so that several guide blocks 16 are all in the center of the connecting pipe 3. At the same time, the guide block 16 is connected to the refrigeration plate 13 through the iron sheet 60. Therefore, when the refrigeration plate 13 emits cold air, the cold air will be quickly transferred to the surface of the guide block 16 through the iron sheet 60.
当电机1驱动水泵开始工作，工业热废水吸入连接管3内，热水进入连接管3内后会先被预冷的连接管3进行降温，当接触到导流块16时会再次被降温，同时三角形的导流块16对水进行导流，部分水通过导流槽181穿过导流块16，而另一部分的水则通过导流块16的两侧和圆角182穿过，并在两个导流块16之间形成回流进行冷却。当盖板14打开时会通过一侧的顶板36与回流板32上的凸板33接触，并带动顶板36和回流板32向远离回流槽31的方向移动，回流板32会通过弹性绳带着端盖34打开，从而让被盖板14挡住的部分水流通过弧形的凸板33和回流板32被导入回流槽31内进行回流冷却。When the motor 1 drives the water pump to start working, the industrial hot wastewater is sucked into the connecting pipe 3. After the hot water enters the connecting pipe 3, it will be cooled by the pre-cooled connecting pipe 3 first, and will be cooled again when it contacts the guide block 16. At the same time, the triangular guide block 16 guides the water. Part of the water passes through the guide block 16 through the guide groove 181, while the other part of the water passes through the two sides and the fillet 182 of the guide block 16, and forms a reflux between the two guide blocks 16 for cooling. When the cover plate 14 is opened, the top plate 36 on one side will contact the convex plate 33 on the return plate 32, and drive the top plate 36 and the return plate 32 to move away from the return groove 31. The return plate 32 will open with the end cover 34 through the elastic rope, so that part of the water blocked by the cover plate 14 will be introduced into the return groove 31 through the arc-shaped convex plate 33 and the return plate 32 for reflux cooling.
