[0022] A drain pipe 18 is provided at the bottom of the barrel body 1 .

[0023] In this embodiment, the aqueous ink enters the filter cartridge 5, and the aqueous ink is filtered from the inside to the outside. The filtered aqueous ink flows out of the barrel 1 through the ink inlet tube 3; the particulate impurities in the aqueous ink are filtered to the filter cartridge 5, thereby realizing the filtering function;

[0024] When the utility model performs filtering operation, in order to prevent the filter holes from being blocked by larger particles and reduce the filtering effect, the one-way valve 12 on the pipeline connected to the water source and the one-way valve 12 on the pipeline connected to the inner flushing pipe 8 are closed, the booster pump 11 is started, and the water-based ink is extracted. The water-based ink is sprayed from the outside of the filter cartridge 5 to the inside through the flushing nozzle 10.

[0029] As a technical optimization solution of the utility model, a motor 23, a driving wheel 24 and an engaging sleeve 25 are arranged on the top of the cover body 2. The driving wheel 24 is arranged at the output end of the motor 23 through a rotating shaft, and the engaging sleeve 25 is arranged on the outer wall of the inner flushing tube 8. The driving wheel 24 is engaged with the engaging sleeve 25.

[0030] In this embodiment, by starting the motor 23, the driving wheel 24 and the engagement sleeve 25 are engaged, so that the inner flushing tube 8 can realize the function of rotating and flushing, and the inner wall of the filter cartridge 5 can be fully flushed.

The water pressure can make the particles blocked on the inner wall of the filter cartridge 5 detach from the inside of the filter cartridge 5, and the flushing nozzle 10 on the inner flushing pipe 8 can flush the inner wall of the filter cartridge 5 to prevent impurities from clogging and accumulating on the filter holes; when the water-based ink flows to the ink outlet pipe 4 through the slag discharge pipe 13, the impurities can flow into the slag discharge pipe 13, and the filter plate 14 ensures that both large and small particles of impurities will not flow into the ink outlet pipe 4;

[0034] After the filtering device completes the filtering operation; open the one-way valve 12 on the water source pipe, start the booster pump 11, and deliver clean water to the inner flushing pipe 8 and the outer flushing pipe 6, so that the filter cartridge 5 can be flushed again, open the second threaded cover 16 and the drain pipe 18, and the cleaned sewage and impurities can be discharged together, rotate and open the first threaded cover 15, and the filter plate 14 can be taken out from the slag discharge pipe 13, and the filter plate 14 can be cleaned and replaced.
