The right side of the top of the box body 1 is connected to a workbench 8 by bolts. Rectangular plates 9 are riveted to the tops of both sides of the inner cavity of the box body 1. An electromagnet 10 is embedded and installed on the top of the rectangular plate 9. A cleaning mechanism 11 is movably connected to the front side of the right side of the inner cavity of the box body 1 through a bearing. The cleaning mechanism 11 includes a screw rod 12. A scraper 13 is provided on the right side of the threaded sleeve on the surface of the screw rod 12. A cooling mechanism 14 is connected to the bottom of the inner cavity of the box body 1 by bolts. The cooling mechanism 14 includes a water pump 15. The water outlet end of the water pump 15 passes through the first partition plate 4 and is connected to a heat exchange pipe 16. A semiconductor refrigerator 17 is fixedly connected to the bottom of the left side of the box body 1.

[0025] The top of the left side of the box body 1 is connected to a servo motor 18 by bolts. The output end of the servo motor 18 passes through the inner cavity of the box body 1 and is connected to the screw rod 12 by bolts. The rear sides of both sides of the scraper 13 are movably connected with guide rods 19. Both ends of the guide rods 19 are riveted to the inner wall of the box body 1, and the bottom of the scraper 13 is in contact with the rectangular plate 9.

[0026] The water inlet end of the water pump 15 passes through the right side of the second partition 5, and the left end of the heat exchange tube 16 is connected to the water supply pipe 20. The end of the water supply pipe 20 away from the heat exchange tube 16 passes through the box body 1, the cover shell 2 and the baffle 3 in sequence and is connected to the universal pipe 21.

[0027] A rectangular hole 22 is defined in the top of the housing 1, and a filter hole 23 is defined on the right side of the top of the rectangular plate 9. A sealing plate is bolted to the right side of the front of the housing 1. The output end of the drive motor 7 passes through the support platform 6 and is bolted to a collet 24. A frame 25 is riveted to the right side of the bottom of the rectangular plate 9. A filter screen 26 is movably connected to the sides of the inner cavity of the frame 25 via slide rails. A drainage hole is defined at the bottom of the frame 25.

[0028] A temperature sensor 27 is bolted to the left side of the bottom of the inner cavity of the box 1, and a cooling fin 28 is fixedly connected to the cooling end of the semiconductor cooler 17. A panel 29 is riveted to the top of the box 1, and a liquid level window is embedded in the front of the box 1.
