[0033] A stirring barrel 2, the stirring barrel 2 is fixed on the bottom plate 1, a stirring cavity 3 is arranged in the stirring barrel 2, a stirring motor 4 is fixed on the upper side of the stirring barrel 2, a stirring shaft 5 is fixed on the rotating shaft of the stirring motor 4, the stirring shaft 5 is located in the stirring cavity 3, a plurality of stirring blades 6 are fixed on the stirring shaft 5, and a liquid discharge pipe 7 is connected to the stirring barrel 2;

[0034] The filter device comprises a filter box 8, a filter cavity 9 with an upward opening is provided in the filter box 8, a filter inlet 10 and a filter outlet 11 are provided on the side wall of the filter box 8, the filter inlet 10 is connected with the drain pipe 7, a slot 12 is provided in the filter cavity 9, a filter plate 13 is inserted in the slot 12, and a cover plate 14 is detachably connected to the filter box 8, and the cover plate 14 is used to open or close the opening of the filter cavity 9;

[0035] The filter outlet 11 is connected to a spray gun 15 .

[0036] The raw material enters the filter box 8 through the filter inlet 10, and the filter plate 13 can filter the raw material to prevent the spray gun 15 from being blocked. When the filter plate 13 needs to be cleaned, it is only necessary to open the cover plate 14 and then remove the filter plate 13 from the slot 12, so that the filter plate 13 can be cleaned or replaced with a new one, which is very convenient to clean.

[0037] like Figure 1 and Figure 2 As shown, the filtering device also includes a lifting seat 16, side panels 17 are fixed on both sides of the filtering box 8, and fixed shafts 18 are fixed on the two side panels 17. Two lifting through holes 19 are provided on the lifting seat 16, and the two fixed shafts 18 pass through the two lifting through holes 19 respectively. The cover plate 14 is fixed on the lifting seat 16.
