The exhaust box 20 contains a fan, which can transport the gas inside the filter cartridge 10 from the conveying pipe 21 to the interior of the filter box 22. At the same time, the activated carbon adsorption mesh inside the filter box 22 can adsorb odors in the gas.

[0022] In one embodiment of this utility model, a snap-fit ​​block 31 is arranged inside the connecting groove 30, and a positioning bolt 32 is inserted inside the snap-fit ​​block 31. The gas inside the exhaust box 20 contains a fan, which can transport the gas inside the filter cartridge 10 from the conveying pipe 21 to the inside of the filter box 22. At the same time, the filter box 22 contains an activated carbon adsorption mesh, which can adsorb odors in the gas.

[0024] In one embodiment, a coarse filter disc 35 is disposed on the inner wall of the connecting rod 34, and a fine filter disc 36 is disposed below the coarse filter disc 35. The filter screen 33 can filter impurity particles in the aromatic solvent. At the same time, the coarse filter disc 35 and the fine filter disc 36 have different pore sizes, which can achieve a highly efficient filtration effect on the aromatic solvent.

[0025] In one embodiment, the end of the connecting pipe 40 is provided with a ring pipe 41, and a high-pressure liquid outlet nozzle 42 is installed on the bottom surface of the ring pipe 41. The ring pipe 41 can uniformly deliver the aromatic solvent to the high-pressure liquid outlet nozzle 42, and the aromatic solvent is sprayed onto the filter screen 33 through the high-pressure liquid outlet nozzle 42 to avoid the aromatic solvent from accumulating in one place for filtration.

Then, the sealing cover 12 is closed, and the aromatic solvent is transported from the inlet pipe 13 to the inside of the ring pipe 41. The ring pipe 41 can process the aromatic solvent... The hydrocarbon solvent is uniformly delivered to the high-pressure liquid outlet nozzle 42. The aromatic solvent is sprayed onto the filter screen 33 through the high-pressure liquid outlet nozzle 42 to prevent the aromatic solvent from accumulating in one place. The aromatic solvent passes through the filter screen 33, the coarse filter element disc 35 and the fine filter element disc 36 in sequence. The filtered solution is discharged from the outlet at the bottom of the filter cylinder 10. The gas inside the exhaust box 20, which contains a fan, can transport the gas inside the filter cylinder 10 to the inside of the filter box 22 through the delivery pipe 21. At the same time, the filter box 22 contains an activated carbon adsorption mesh, which can adsorb the odor in the gas.
