By disassembling the conical water inlet cover 8, the equipment in the water inlet cylinder 7 can be cleaned, installed and maintained.

[0062] As mentioned above, the drainage group 002 is arranged on the pump seat 1 through the drainage plate 4. The drainage group 002 includes a drainage cylinder 10, a conical drainage cover 11 and a drainage elbow 12. The drainage cylinder 10 is arranged on the drainage plate 4. One end of the drainage cylinder 10 is rotatable and sealedly connected with the other end of the pump body power ring 5. The conical drainage cover 11 is arranged at the other end of the drainage cylinder 10, and the drainage elbow 12 is connected and arranged on the conical drainage cover 11.

[0064] Specifically, by rotatably setting the pump body power ring 5 between the water inlet group 001 and the drainage group 002, the rotation of the pump body power ring 5 can drive the power blades 6 to rotate, thereby providing suction to the transported medium, and when the power blades 6 are severely damaged, the power blades 6 can be replaced on the outside of the pump body power ring 5, so that maintenance is simpler and more convenient.

[0065] As mentioned above, the power mechanism 003 is arranged on the power plate 2, and the power mechanism 003 is connected to the pump body power ring 5, and is used to drive the pump body power ring 5 to rotate.

[0066] Specifically, the power motor 14 is started, and the output end of the power motor 14 drives the power rotating rod 13 to rotate through the transmission belt pulley group. The rotation of the power rotating rod 13 drives the power pinion 16 to rotate, and the power pinion 16 drives the power gear 15 to rotate. The power gear 15 drives the pump body power ring 5 to rotate, and the pump body power ring 5 drives the power blades 6 to rotate. Through the rotation of the power blades 6, the air pressure in the water inlet cylinder 7 flows toward one side of the drainage cylinder 10. Under the action of the air pressure, the medium is sucked into the water inlet cylinder 7 through the water inlet pipe 9.

[0067] As mentioned above, the filter mechanism 004 is arranged throughout the water inlet group 001, the pump body power ring 5 and the drainage group 002, and the filter mechanism 004 is connected to the power mechanism 003, and is used to filter large particles of hard objects in the medium in the water inlet group 001, and is used to automatically discharge large particles of hard objects.

[0068] The slag conveying assembly includes a slag conveying rotating rod 20, a spiral slag conveying blade 21, a bevel gear 1 22, a steering rotating rod 23, a bevel gear 25, a bevel gear 3 26, a bevel gear 4 27 and a gear box 28. The slag conveying rotating rod 20 penetrates and is sealed and rotatably arranged in the filter pipe 17. The spiral slag conveying blade 21 is arranged on the slag conveying rotating rod 20, and the spiral slag conveying blade 21 contacts the inner wall of the filter pipe 17. The bevel gear 1 22 is arranged on the power rotating rod 13. The steering rotating rod 23 passes through the filter pipe 17 and is sealed and rotatably arranged in the filter pipe 17. The rotating seat 24 is rotatably arranged on one side of the power plate 2, the bevel gear 2 25 is arranged on the steering rod 23, the bevel gear 2 25 is meshed with the bevel gear 1 22, the bevel gear 3 26 is arranged on the steering rod 23, the bevel gear 4 27 is arranged on the slag conveying rod 20, the bevel gear 4 27 is meshed with the bevel gear 3 26, the gear box 28 is arranged on the power plate 2, and the bevel gear 1 22, the bevel gear 2 25, the bevel gear 3 26 and the bevel gear 4 27 are all arranged in the gear box 28.

[0069] Among them, the scraping assembly includes a scraping block 29 and a scraping rod 30. The scraping block 29 is arranged on the side of the scraping rod 20 close to the filter plate 19. There are multiple scraping rods 30. The scraping rods 30 are detachably arranged on the scraping block 29. The scraping rods 30 are in contact with the side of the filter plate 19 close to the water inlet pipe 9.

[0070] Specifically, after the medium enters the water inlet cylinder 7, when the medium passes through the filter plate 19, large particles and hard objects in the medium can be filtered, and the power rotating rod 13 rotates while driving the bevel gear 1 22 to rotate, the bevel gear 1 22 drives the bevel gear 2 25 to rotate, the bevel gear 2 25 drives the steering rotating rod 23 to rotate, the steering rotating rod 23 drives the bevel gear 3 26 to rotate, the bevel gear 3 26 drives the bevel gear 4 27 to rotate, the bevel gear 4 27 drives the slag conveying rotating rod 20 to rotate, the slag conveying rotating rod 20 drives the spiral slag conveying blade 21 to rotate, the rotation of the slag conveying rotating rod 20 also drives the scraping block 29 and the scraping rod 30 to rotate, through the rotation of the scraping rod 30, the particles on the filter plate 19 are scraped toward the inside of the filter pipe 17, and the filter plate 19 is cleaned.

[0071] As mentioned above, the side of the filter pipe 17 close to the drainage elbow 12 is also connected to a slag collecting box 31, which is arranged on the pump seat 1.

The particles entering the filter pipe 17 will be transported into the slag collecting box 31 under the rotation of the spiral slag conveying blade 21, and the large particles and hard objects in the medium will be collected through the slag collecting box 31.

[0072] It should be noted that since the slag box 31 is sealed, when the power blades 6 rotate, the pressure in the water inlet cylinder 7 is lower than the pressure in the water outlet cylinder 10, and thus the sucked medium will not enter the filter pipe 17. As the hard particles scraped off by the scraper rod 30 continue to increase, the hard particles will not pass through the filter plate 19. As the hard particles accumulate and gather in the filter pipe 17, they will be transported to the slag box 31 as the spiral slag conveying blades 21 rotate. Even if the slag box 31 contains a solution, due to the different densities between the solution and the hard particles, the solution will be squeezed out as the hard particles gather, and the solution will be pumped out through the filter plate 19.

[0073] As mentioned above, a blade changing cover 33 is detachably provided between the water inlet plate 3 and the drainage plate 4, and the large power gear 15 and the small power gear 16 are both located in the blade changing cover 33. By removing the blade changing cover 33, the power blades 6 can be replaced outside the power ring 5 of the pump body.

[0074] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
