[0025] As a preferred embodiment, in order to facilitate the temporary storage of impurities, the precipitation of impurities, and the subsequent centralized cleaning of impurities, a temporary storage mechanism 7 is provided on the surface of the impurity conveying mechanism 6. The temporary storage mechanism 7 includes a temporary storage cylinder 701, which is connected to the side of the open transmission cylinder 601. A filter screen cylinder 704 is placed inside the temporary storage cylinder 701. A cylinder cover 702 is installed on the top of the temporary storage cylinder 701 by bolts. A plurality of material transfer plates 703 used in conjunction with the filter screen cylinder 704 are equidistantly and fixedly connected to the surface of the transmission shaft 602.

[0026] During use: after water flows into the filter box 2, the arc filter frame 3 and filter holes 4 inside the filter box 2 will separate impurities from the water source at the inlet of the water pump body 1. During the separation process, the drive motor 501 is started synchronously, and the drive motor 501 drives the reciprocating screw 502 to rotate, prompting the threaded sleeve 503 on the surface of the reciprocating screw 502 to drive the tooth plate 504 to move back and forth, and the tooth plate 504 reciprocates and meshes with the gear 506, prompting the rotating shaft 505 to drive the mounting plate 507 and the drum 508 to rotate and swing back and forth.

[0027] During the period when the mounting plate 507 drives the roller 508 to swing back and forth, the mounting plate 507 synchronously drives the slide bar 511, the cross slip ring 513 and the outer scraper 514 to swing.

The outer scraper 514 scrapes away the impurities back and forth and guides the impurities to the inlet of the open transmission cylinder 601.

[0028] The reciprocating screw 502 rotates and synchronously drives the transfer rod 607 to rotate through the meshing of two bevel gears 608. The transfer rod 607 synchronously rotates the left transmission shaft 602 through the transmission cooperation of the second pulley 609 and the second belt 610. The left transmission shaft 602 synchronously drives the right transmission shaft 602 to rotate through the transmission cooperation of the first pulley 605 and the first belt 606. The rotation of the transmission shaft 602 drives the spiral blades 603 to spirally transmit impurities, so that the impurities entering the open transmission cylinder 601 are continuously transmitted to the temporary storage space at the top of the inner cavity of the open transmission cylinder 601.

[0029] The transmission shaft 602 rotates while simultaneously driving the material-dispensing plate 703 to rotate. The rotation of the material-dispensing plate 703 will centrally displace the spirally ascending impurities into the temporary storage cylinder 701. After entering the temporary storage cylinder 701, the impurities gradually settle into the filter cylinder 704 to be taken out and centrally processed at regular intervals.
