The upper right end of the second filter housing 12 is connected to a third slag outlet pipe 17. Electric valves 18 are installed in the third slag outlet pipe 17, the first slag outlet pipe 15, and the second slag outlet pipe 16.

[0022] The first filter housing 11 is fixed with a control device for controlling the overall equipment;

[0023] Specifically, a support frame is fixed on the outer wall of the first filter housing 11. There are four sets of support frames, and the four sets of first filter housings 11 are distributed at equal distances on the first filter housing 11.

[0024] Furthermore, six sets of bolts 23 are passed through the first filter housing 11, the second filter housing 12, and the sealing cover 13. The six sets of bolts 23 are evenly distributed on the first filter housing 11, the second filter housing 12, and the sealing cover 13. Rubber sealing rings are provided between the first filter housing 11, the second filter housing 12, and the sealing cover 13 to ensure the sealing effect.

[0025] In the above scheme, the second filter housing 12 is placed on the first filter housing 11 and fixed with bolts 23. The sealing cover 13 is attached to the second filter housing 12 and sealed with bolts 23. The water inlet pipe 14 passes through the first filter housing 11 and is threadedly sealed to the first limiting ring 242 on the filter basket 241. A sealing ring is provided at the connection between the water inlet pipe 14 and the first filter housing 11. The fluid to be filtered enters the filter assembly 24 through the water inlet pipe 14. The waste generated during cleaning is discharged through the first slag discharge pipe 15, the second slag discharge pipe 16 and the third slag discharge pipe 17.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, a basket filter structure 2 is disassembled and installed inside the filter box assembly 1 for impurity filtration. The basket filter structure 2 includes a first hollow annular support plate 21. The first hollow annular support plate 21 is disassembled and installed with a filter screen ring 22 by bolts 23. A filter assembly 24 is fixed on the filter screen ring 22. The filter assembly 24 includes a filter basket 241. A first limiting ring 242 passes through the filter basket 241. The filter basket 241 is located between annular filter screens 243. A second limiting ring 244 is fixed on the lower side of the annular filter screens 243. The second limiting ring 244 is limited in a limiting groove 245. The limiting groove 245 is opened on the first filter housing 11.
