Valves are provided on the surfaces of the rubber inlet pipe 2 and the rubber outlet pipe 3. Three filter mesh plates 4 are provided in the inner cavity of the filter tank 1. The mesh sizes of the three filter mesh plates 4 are different, and the mesh sizes of the three filter mesh plates 4 decrease from top to bottom.

[0026] A storage cavity 5 is reserved on the upper surface of the filter screen plate 4 .

[0027] When the multi-layer filter device for liquid adhesive is used, liquid adhesive is added into the filter tank 1 through the adhesive inlet pipe 2, and the adhesive is subjected to multi-layer filtration by the filter screen plate 4. Impurities are trapped in the storage cavity 5, and the filtered product is discharged from the filter tank 1 through the adhesive outlet pipe 3.

[0028] Three slots are provided on the left side of the filter tank 1 , and three filter screens 4 are respectively inserted into the slots. A sealing plate 12 is fixedly installed on the left ends of the three filter screens 4 , and the sealing plate 12 is detachably installed on the left side wall of the filter tank 1 by bolts.

[0029] After the filtering action is finished, the filter screen plate 4 is quickly pulled out through the sealing plate 12 to facilitate cleaning of the impurities inside the storage cavity 5 .

[0030] A cleaning and pressurizing assembly is provided on the side wall of the filter tank 1 corresponding to the filter screen plate 4 .

[0031] The cleaning and pressurizing assembly includes three reciprocating slide rods 6 slidably connected to the side wall of the filter tank 1.
