When the water pump works, the filtering mechanism is installed on the existing water pump in the working process and used for preventing blockage, so that the working efficiency of the water pump is improved. When the water pump is used for pumping industrial wastewater, the service life of the impeller of the water pump is more required to be considered, so that the working efficiency is improved. When the water pump is extracting industrial hot waste water, the electric telescopic rod 12 in the rectangular frame 11 is started in advance, the electric telescopic rod 12 pushes the refrigerating sheet 13 to move towards the inside of the connecting pipe 3, the bottom of the refrigerating sheet 13 is contacted with the roller 50 made of rubber, the roller 50 plays a role in assisting in opening the cover plate 14, the cover plate 14 is pushed to rotate towards the inside of the connecting pipe 3, and therefore a square groove in the connecting pipe 3 is opened, and the refrigerating surface of the refrigerating sheet 13 is exposed in the connecting pipe 3. Along with the continuous reduction of the temperature of the body of refrigeration piece 13 to play the effect of heat absorption refrigeration cooling to its surrounding air, thereby form the air conditioning in connecting pipe 3 gradually, until the air conditioning is diffused in connecting pipe 3, and then reach the effect of cooling down in advance fast in connecting pipe 3 inside, apron 14 can bring push rod 171 and guide block 16 contact simultaneously when opening, let guide block 16 move to connecting pipe 3 center department under the effect of connecting rod 15, connecting rod 15 can bring next guide block 16 together through dead lever 172 when moving, make a plurality of guide block 16 all be in connecting pipe 3 center department, guide block 16 is hollow through iron sheet 60 (the air core is just under iron sheet 60, so it can not be blocked when following refrigeration piece 13 and move), so refrigeration piece 13 is when giving off the air conditioning, the air conditioning can be transmitted to guide block 16 surface through iron sheet 60 fast, make the surface of guide block 16 possess the effect of low temperature. According to actual use condition, the refrigerating plate 13 is in sliding sealing connection with the rectangular frame 11, and meanwhile, for heat dissipation, a heat dissipation hole is formed in the rectangular frame 11, or a heat dissipation mechanism is arranged in the rectangular frame.
Meanwhile, the connecting rod 15 moves together with the anti-slip rope 43 when moving, so that the rotating shaft 42 rotates, the rotating shaft 42 rotates by 90 degrees with the heat exchange tube 41, the contact area between the heat exchange tube 41 and water is enlarged, the cooling effect is improved, and when the connecting rod 15 resets, the rotating shaft 42 follows the heat exchange tube 41 to reset, so that the influence on water flow is reduced. It should be noted that, when the working is started in advance, the water inlet end and the water outlet end of the heat exchange 41 are both communicated with an external container, and a heat exchange medium (water or other low-temperature fluid medium can be selected) is arranged in the container, and through the use of an external circulating pump, the whole 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 shell 2 starts working to suck industrial hot wastewater into the connecting tube 3, the hot water enters the connecting tube 3 and is cooled by the precooled connecting tube 3, the water is cooled again when contacting the guiding block 16, meanwhile, the triangular guiding block 16 guides the water, part of the water passes through the guiding block 16 through the guiding grooves 181, and the other part of the water passes through both sides and the round corners 182 of the guiding block 16, and forms reflux between the two guiding blocks 16, so that the residence time of the water in the connecting tube 3 is prolonged again, the hot water is cooled conveniently, and the gap between the two guiding blocks is small, so that the water can accelerate the water flow to pass through the total cooling time of the connecting tube 3, and the cooling effect of the whole time of the connecting tube can not be changed. When water flows through the guide block 16 and then contacts the refrigerating piece 13 to cool again, and flows into the pump shell 2 through the through groove 19 on the end cover 34 to be pumped away, the refrigerating piece 13 and the end cover 34 designed through the design can cool the hot water, so that the pressure at the inlet of the water pump is easier to be lower than the saturated steam pressure of the water because the water temperature is higher and the saturated steam pressure is higher, cavitation is generated, and the pressure is reduced through the design of the end cover 34, so that the cavitation phenomenon of the impeller is greatly reduced, and the water pump can operate efficiently for a long time. The amount of the cooling medium in the external container is determined according to the waste water extracted by the belt, and specifically, a temperature sensor may be disposed in the container, so that when the temperature of the cooling medium in the external container is significantly increased, the heat exchange efficiency is greatly reduced, and a new container and the cooling medium to be subjected to heat exchange may be selected to be replaced.
