本发明涉及液体泵领域，具体地说，涉及一种蠕动泵。The invention relates to the field of liquid pumps, in particular to a peristaltic pump.
背景技术Background technique
蠕动泵通过对泵的弹性输送软管交替进行挤压和释放来泵送流体，通常用于液体计量灌装领域，如医疗检测及化学检测试剂的定量加注等，其工作原理一般是通过挤压辊绕与其轴平行的一转动轴在泵壳内旋转，挤压并推动弹性输送软管内的液体向前运动，使弹性输送软管后端产生真空，将液体吸入弹性输送软管内，由后面跟进的挤压辊进一步推动前进，从而定量运输液体。The peristaltic pump pumps fluid by alternately squeezing and releasing the elastic delivery hose of the pump. It is usually used in the field of liquid metering and filling, such as quantitative filling of medical testing and chemical testing reagents. Its working principle is generally through squeezing The pressure roller rotates in the pump casing around a rotating shaft parallel to its axis, squeezes and pushes the liquid in the elastic delivery hose to move forward, so that a vacuum is generated at the rear end of the elastic delivery hose, and the liquid is sucked into the elastic delivery hose. It is further pushed forward by the following squeeze roller, so that the liquid is transported quantitatively.
采用蠕动泵进行液体输送时，除软管外，所输送产品不与泵体直接接触，且重复精度及稳定性都较高，无液体空运转情况下不会对泵的任何部件造成损害，可输送各种具有腐蚀、氧敏感特性的医疗试剂、化学试剂、其他物料及各种食品等。在使用时，仅软管为需要替换的部件，且更换操作较简单，因而蠕动泵被广泛的运用于各种流体的输送。When the peristaltic pump is used for liquid transportation, except for the hose, the product to be conveyed does not directly contact the pump body, and the repeatability and stability are high. It will not cause damage to any part of the pump under the condition of dry running without liquid. Conveying various medical reagents, chemical reagents, other materials and various foods with corrosion and oxygen-sensitive characteristics. When in use, only the hose is the part that needs to be replaced, and the replacement operation is relatively simple, so the peristaltic pump is widely used in the delivery of various fluids.
中国实用新型专利CN201953621U公开了这样一种蠕动泵泵头，包括前撑板6、后撑板5、设置在所述前撑板和后撑板之间的上压块8和卡管装置11，设置在前撑板和后撑板的中心孔处的滚轮装置，所述前撑板和后撑板之间形成有第一滑槽51，所述上压块上设有与所述第一滑槽滑配的滑块81，所述第一滑槽的底部设有卡配所述滑块的卡装部（即：卡槽）。上压块8利用自身的弹性，将其滑块压入第一滑槽，在进入卡装部后释放，借助自身弹性，上压块恢复原有形态，自动固定在工作位置。该实用新型公开的蠕动泵泵头存在以下3个问题，问题1：上压块8必须具有弹性，否则难以完成装配；问题2：蠕动泵泵头依靠上压块8、滚轮12和输送液体的软管（未示出）配合来实现液体的输送，由于上压块8具备弹性，刚性强度低，仅适合一条或两条管路输送，无法实现多管路输送，如果需要多管路输送，则需要采用多个蠕动泵并联同时工作，使液体输送的成本增加；问题3：也正由于上压块8具备弹性，蠕动泵泵头长期工作后，容易发生形变，很难保证定量输送液体。Chinese utility model patent CN201953621U discloses such a pump head of a peristaltic pump, which includes a front brace 6, a rear brace 5, an upper pressure block 8 and a tube clamping device 11 arranged between the front brace and the rear brace, The roller device is arranged at the central hole of the front stretcher and the rear stretcher, a first sliding groove 51 is formed between the front stretcher and the rear stretcher, and the upper pressing block is provided with the first sliding groove 51. The sliding block 81 is slidably matched with the slot, and the bottom of the first sliding slot is provided with a fastening part (that is, a fastening slot) that is fastened with the sliding block. The upper pressing block 8 utilizes its own elasticity to press its slide block into the first chute, and releases after entering the clamping part. By virtue of its own elasticity, the upper pressing block recovers its original form and is automatically fixed at the working position. The peristaltic pump head disclosed in this utility model has the following three problems. Problem 1: The upper block 8 must be elastic, otherwise it is difficult to complete the assembly; Problem 2: The pump head of the peristaltic pump relies on the upper block 8, the roller 12, and The hose (not shown) cooperates to realize the transportation of the liquid. Since the upper pressure block 8 has elasticity and low rigidity, it is only suitable for one or two pipelines, and it cannot realize multi-pipeline transportation. If multi-pipeline transportation is required, It is necessary to use multiple peristaltic pumps to work in parallel at the same time, which increases the cost of liquid transportation; problem 3: also because the upper pressing block 8 is elastic, the pump head of the peristaltic pump is prone to deformation after long-term operation, and it is difficult to ensure quantitative delivery of liquid.

There are more than two squeeze rollers, which are equidistant and symmetrical to the central axis. The hose used to transport the liquid is arranged between the squeeze roller and the pump casing, and is squeezed by the squeeze roller. Drive the squeeze roller to rotate, so that the liquid in the hose is transported along the rotation direction of the rotating disk. Two or more hoses are arranged side by side along the axial direction of the squeeze roller. The pump casing is made of rigid material with no elasticity. The hose enters the pump casing from the hose inlet surface of the pump casing, and is led out from the hose outlet surface of the pump casing. The hose inlet surface and the hose outlet surface are the same side of the pump casing. The pump casing includes an upper pump casing, a lower pump casing and a middle part. The first rotating disk is arranged on the upper pump casing, the second rotating disk is arranged on the lower pump casing, and the part of the hose located in the pump casing is arranged on the middle part and squeezed. Between the rollers, the middle part is "concave" with an opening, and the surface opposite to the opening is a circular arc surface. The hose enters the pump casing through the opening groove arranged on the upper or lower pump casing, and passes through The opening groove on the other side of the pump casing or the lower pump casing leads out, and the middle part closes the opening part of the opening groove.
由以上方案可见，软管设置在挤压辊与刚性泵壳之间，且受挤压辊挤压，转动盘转动时带动挤压辊转动，从而将软管内的液体沿转动盘的转动方向输送，以实现软管内液体的稳定输送，且多个软管可沿挤压辊的长度方向并排设置，当挤压辊的长度较长时，可排列较多的管路，从而实现多管路输送。泵壳用刚性材料制成，使泵壳具有较高强度，不易产生变形，可实现液体的稳定输送。软管从泵壳的同一侧面进出，软管可在较大范围内被挤压辊挤压推送液体，从而输送更稳定。软管可通过开口槽安装在泵壳上，且开口槽的开口部分可被中间部分封闭，从而实现软管的固定，而且在需要更换软管时，只需将中间部分取下，即可露出软管，以实现轻松更换，方便检修。It can be seen from the above scheme that the hose is arranged between the squeeze roller and the rigid pump casing, and is squeezed by the squeeze roller. When the rotating disc rotates, it drives the squeezing roller to rotate, so that the liquid in the hose is moved along the direction of rotation of the rotating disc. To realize the stable delivery of the liquid in the hose, and multiple hoses can be arranged side by side along the length of the squeeze roller. When the length of the squeeze roller is longer, more pipelines can be arranged to achieve multi-tube road transport. The pump casing is made of rigid materials, so that the pump casing has high strength, is not easy to deform, and can realize stable delivery of liquid. The hose enters and exits from the same side of the pump casing, and the hose can be squeezed and pushed by the squeeze roller in a wide range, so that the delivery is more stable. The hose can be installed on the pump casing through the opening groove, and the opening part of the opening groove can be closed by the middle part, so as to realize the fixing of the hose, and when the hose needs to be replaced, only the middle part needs to be removed to reveal Hoses for easy replacement and easy access.

Flexible, wherein both ends of the main shaft 23 can be connected with the drive shaft to drive the rotating disk to rotate, so that the drive can be more flexible, the installation is also more convenient, and the transportation in two directions can be easily realized. The central axis of the rotating disk coincides with the central axis of the main shaft 23, and the three squeeze rollers 24 are arranged equidistantly and symmetrically with respect to the central axis. Between, and squeezed by the squeeze roller 24 and the middle part 12, the dotted line in Fig. 3 shows the hypothetical position when the hose is not squeezed.
第一转动盘21位于上泵壳11内，主轴23伸出至从上泵壳11的顶面露出，以与驱动轴连接，第二转动盘22位于下泵壳13的空腔内，漏液收集槽131位于第二转动盘22与空腔底面之间，润湿性材料6与漏液收集槽131连通。The first rotating disk 21 is located in the upper pump casing 11, the main shaft 23 protrudes to be exposed from the top surface of the upper pump casing 11 to be connected with the drive shaft, the second rotating disk 22 is located in the cavity of the lower pump casing 13, and the leakage The collecting tank 131 is located between the second rotating disk 22 and the bottom surface of the cavity, and the wettable material 6 communicates with the leaking liquid collecting tank 131 .

当连接软管52或接头51部分渗漏时，渗漏出的液体会流入漏液收集槽131内，与漏液收集槽131连通润湿性材料6的颜色会产生变化，从而提醒用户有漏液产生。此时，只需拆卸下螺钉4，沿远离软管引入面的方向取下中间部分12即可露出连接软管52及接头51，检查处理或更换有问题的连接软管或接头后，将中间部分12插回，导向槽122沿引导条133滑动，至中间部分12的两侧完全闭合开口槽133的开口部分且与软管引入面相对的另一面，中间部分12与上泵壳11、下泵壳13位于同一平面即可，蠕动泵即可重新使用。When the connecting hose 52 or the joint 51 partially leaks, the leaked liquid will flow into the leakage collection tank 131, and the color of the wettability material 6 connected with the leakage collection tank 131 will change, thereby reminding the user that there is a leak. liquid produced. At this time, only need to disassemble the screw 4, and remove the middle part 12 along the direction away from the hose introduction surface to expose the connecting hose 52 and the joint 51. The part 12 is inserted back, and the guide groove 122 slides along the guide bar 133 until the two sides of the middle part 12 completely close the opening part of the opening groove 133 and the other side opposite to the hose introduction surface, the middle part 12 is connected with the upper pump casing 11, the lower The pump casing 13 only needs to be located on the same plane, and the peristaltic pump can be reused.

Referring to accompanying drawings 11 to 13 , two annular grooves 241 matching the arc-shaped partition wall 124 are provided on the circumference of the squeezed roller 24 . Referring to Figure 15, when the peristaltic pump is working, the arc-shaped partition wall 124 extends into the annular groove 241, and the function of the limiting hose is realized through the cooperation of the arc-shaped partition wall 124 and the annular groove 241, avoiding The hose is deflected, and the partition wall at the transition surface enables the guidance of the squeeze roller 24 . In other embodiments, the partition wall can be arranged on the extrusion roller to form an annular partition wall, and the groove provided on the middle part to cooperate with the partition wall is formed as an arc-shaped groove.
图中示出了采用两个弧形分隔壁分别与两个环形凹槽配合来隔离出3个软管容纳空间，从而避免相邻之间的软管发生干涉。可以理解的是，弧形分隔壁与环形凹槽的数量不限2个，可以根据软管的数量来确定弧形分隔壁与环形凹槽的数量。The figure shows that two arc-shaped partition walls are respectively matched with two annular grooves to isolate three hose accommodation spaces, so as to avoid interference between adjacent hoses. It can be understood that the number of arc-shaped partition walls and annular grooves is not limited to two, and the number of arc-shaped partition walls and annular grooves can be determined according to the number of hoses.
在其他实施例中，两转动盘可通过多个连接杆而不是主轴固定连接；软管的数量可为两条或四条；挤压辊可为两个或四个；中间部分可设置引导条而下泵壳上设置导向槽；中间部分的安装引导结构可设置在上泵壳与中间部分上；开口槽可设置在上泵壳上；上泵壳或下泵壳可设置其他限制中间部分沿远离软管引入面的方向脱离的限制结构，而不采用螺钉，如可枢转的限位块等等。In other embodiments, the two rotating discs can be fixedly connected by a plurality of connecting rods instead of the main shaft; the number of hoses can be two or four; the squeeze rollers can be two or four; the middle part can be provided with guide strips and The guide groove is set on the lower pump casing; the installation guide structure of the middle part can be set on the upper pump casing and the middle part; the opening groove can be set on the upper pump casing; The direction of the hose introduction surface is detached from the limiting structure without using screws, such as pivotable limit blocks and the like.
