[0002] The slurry pump is a centrifugal pump in terms of working principle. It is mainly suitable for conveying slurry with high head in zinc hydrometallurgy with corrosion, wear, high temperature, cavitation and high lift. Existing slurry pumps are mostly made of high chromium alloy or stainless steel. They increase the energy of solid-liquid mixed medium by centrifugal force and convert electrical energy into kinetic energy and potential energy of the medium, thus achieving the purpose of pumping slurry in the pipeline.

[0047] Based on Example 2, please refer to Figure 3 and Figure 7As shown, the flexible material cleaning mechanism includes a push plate 31 slidably connected to the transmission box 15, a plurality of cleaning rods 32 slidably connected to the transmission box 15 are fixedly connected to one side of the push plate 31, a first spring 33 fixedly connected to the push plate 31 is fixedly connected in the transmission box 15, an elastic air bag 34 slidably connected to the transmission box 15 is fixedly connected in the transmission box 15 through a pipeline, a water supply mechanism connected to the push plate 31 is provided at the top of the first mounting tube 12, the water supply mechanism is used to supply water to the first mounting tube 12 to inflate the elastic air bag 34, the water supply mechanism includes a water pump 41 fixedly connected to the mounting box 4, a rubber hose 42 is fixedly connected to the output end of the water pump 41, a connecting pipe 43 rotatably connected to the first mounting tube 12 is fixedly connected to one end of the rubber hose 42, and the connecting pipe 43 is fixedly connected to the push plate 31;

[0048] After the impurities stuck in the inner cavity are cleaned, there are some flexible materials such as rubber, cotton, plastic cloth, etc. adhered to the inner cavity of the impeller 2. Since there is no force point, they cannot be cleaned out. At this time, the electromagnet ring 16 is not energized, and then the stainless steel hose 13, the second mounting tube 14 and the transmission box 15 are driven to move up and down and rotate in the inner cavity of the impeller 2. Then, the water from the outside is sent into the first mounting tube 12 and the stainless steel hose 13 through the rubber hose 42 through the water pump 41, and then the stainless steel hose 13 passes the water into the elastic airbag 34 through the pipeline, and then the elastic airbag 34 is inflated, and then the elastic airbag 34 pushes the push plate 31 to move The push plate 31 drives the cleaning rod 32 to move outward from the transmission box 15, so that it moves out of the transmission box 15, and then the cleaning rod 32 moves up and down and rotates in the inner cavity of the impeller 2, so that the cleaning rod 32 stirs in the inner cavity, stirs down the adhered flexible material in the inner cavity, and makes it no longer adhere to the inner cavity of the impeller 2, and then the water pump 41 stops supplying water, and then the elastic airbag 34 is no longer subjected to the water pressure, and the push plate 31 moves under the pulling force of the first spring 33, driving the cleaning rod 32 to shrink into the transmission box 15, and at this time, the flexible material falls off the cleaning rod 32, thereby realizing automatic cleaning of the flexible material adhered to the inner cavity of the impeller 2.

The sprayed water flushes the inner cavity of the impeller 2, so that the impurities embedded in the impeller 2 are fully cleaned out again, further improving the cleaning effect of the impeller 2.

[0052] The working principle of the present invention is as follows: the two transmission plates 11 are driven downward by the driving mechanism, the transmission plate 11 drives the first mounting tube 12 to move downward, the first mounting tube 12 drives the stainless steel hose 13 to move downward, so that the two stainless steel hoses 13 in the two mounting boxes 4 move downward from both sides of the inner cavity of the impeller 2, the stainless steel hose 13 drives the second mounting tube 14 and the transmission box 15 to move downward, so that the transmission box 15 moves into the inner cavity of the impeller 2, and at the same time the transmission plate 11 drives the connecting plate 51 to move downward, and then the first mounting tube 12 is driven to rotate by the transmission mechanism, the first mounting tube 12 drives the stainless steel hose 13 to rotate, the stainless steel hose 13 drives the second mounting tube 14 and the transmission box 15 to rotate, and at the same time cooperates with the conical block 72 at the bottom of the transmission box 15 to move downward, so that the transmission box 15 can move downward while rotating and drill into the inner cavity of the impeller 2, and at the same time the cone block 72 at the bottom of the transmission box 15 can move downward. The conical block 72 cooperates with the telescopic buffer of the second spring 73 to reduce the damage of the conical block 72 to the embedded impeller 2, and at the same time, the transmission box 15 can also smoothly enter the inner cavity of the impeller 2. When the two transmission boxes 15 enter the inner cavity of the impeller 2, the electromagnet ring 16 is energized, and the electromagnet rings 16 on the two transmission boxes 15 are energized to attract each other. At this time, the two electromagnet rings 16 on both sides of the inner cavity of the impeller 2 are adsorbed and fixed to each other, and at the same time, they are fixed in conjunction with the connecting friction pads 18, and then the motor 21 is reversed, thereby driving the transmission plate 11 to move upward, and at this time, the stainless steel hose 13 is driven to move upward, thereby driving the two transmission boxes 15 to move upward, and the debris stuck in the inner cavity of the impeller 2 is pulled out from the inner cavity for cleaning, and reciprocating in sequence, and at the same time, in conjunction with the rotation of the impeller 2, the inner cavity of the next impeller 2 is cleaned, thereby realizing automatic cleaning of the impurities stuck in the inner cavity of the impeller 2.

[0053] After the impurities stuck in the inner cavity are cleaned, there are some flexible materials such as rubber, cotton, plastic cloth, etc. adhered to the inner cavity of the impeller 2. Since there is no force point, they cannot be cleaned out. At this time, the electromagnet ring 16 is not energized, and then the stainless steel hose 13, the second mounting tube 14 and the transmission box 15 are driven to move up and down and rotate in the inner cavity of the impeller 2. Then, the water from the outside is sent into the first mounting tube 12 and the stainless steel hose 13 through the rubber hose 42 through the water pump 41, and then the stainless steel hose 13 passes the water into the elastic airbag 34 through the pipeline, and then the elastic airbag 34 is inflated, and then the elastic airbag 34 pushes the push plate 31 to move , the push plate 31 drives the cleaning rod 32 to move outward from the transmission box 15, so that it moves out of the transmission box 15, and then the cleaning rod 32 moves up and down and rotates in the inner cavity of the impeller 2, so that the cleaning rod 32 stirs in the inner cavity, stirs down the adhered flexible material in the inner cavity, and makes it no longer adhere to the inner cavity of the impeller 2, and then the water pump 41 stops supplying water, and then the elastic airbag 34 is no longer subjected to the water pressure, and the push plate 31 moves under the tension of the first spring 33, driving the cleaning rod 32 to retract into the transmission box 15, and at this time the flexible material falls off the cleaning rod 32, thereby realizing automatic cleaning of the flexible material adhered to the inner cavity of the impeller 2.

[0054] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
