[0029] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0030] like Figures 1 to 5 As shown, the embodiment of the utility model provides a filtering device for printing ink production, including a liquid inlet pipe 1, a filter tank body 2, a bag filter assembly 3, a partition plate 4, a filter element 5 and a liquid outlet pipe 6, wherein the partition plate 4 is arranged in the filter tank body 2, and the partition plate 4 is used to separate the interior of the filter tank body 2 into a first chamber and a second chamber, the liquid inlet pipe 1 is connected to the first chamber, and the liquid inlet pipe 1 is used to pass the printing ink to be filtered into the first chamber, the bag filter assembly 3 is arranged in the first chamber, and the bag filter assembly 3 is used to perform a primary filtering treatment on the printing ink, and the filter element 5 is arranged in the second chamber, and the filter element 5 is used to perform a secondary filtering on the printing ink that has been coarsely filtered Processing, the liquid outlet pipe 6 is arranged at one end of the filter tank body 2 away from the first chamber, and is connected to the second chamber to discharge the filtered printing ink; the partition plate 4 can divide the interior of the filter tank body 2 into two independent chambers, namely the first chamber and the second chamber, so that the filtration process is carried out in stages, and the bag filter assembly 3 is used in the first chamber for preliminary coarse filtration to remove larger particles and impurities, and then the filtered printing ink is transported to the second chamber, and in the second chamber, the printing ink is filtered more finely through the filter element 5 to ensure that the printing ink is more pure. The double filtration method can improve the overall filtration effect, prevent coarse impurities from directly clogging the filter element 5, and extend the service life of the filter element 5.

[0031] like Figure 3 and Figure 4 As shown, the bag filter assembly 3 includes a mounting frame 31, a fixed sleeve 32 and a bag sleeve 33. The fixed sleeve 32 has a receiving channel inside. The partition plate 4 is provided with a liquid outlet 40.

The filtered printing ink can pass through the bag sleeve 33 and flow from the liquid outlet 40 to the second chamber. The fixed sleeve 32 can support the bag sleeve 33 so that the bag sleeve 33 maintains a cylindrical structure. The bag sleeve 33 is made of a fabric permeable material with a small pore size, which can capture undispersed pigments and other solid particles in the ink.

[0035] Furthermore, the filter element 5 is made of glass fiber material. The glass fiber filter element 5 has a high filtering efficiency due to its fine fiber structure, and can capture extremely small particles, including tiny impurities and particulate matter, thereby improving the filtering effect on printing ink.

[0036] like Figure 4 As shown, further, the mounting frame 31 and the fixing sleeve 32 are detachably connected via bolts. Such an arrangement allows operators to quickly disassemble the bag sleeve 33 for cleaning or replacement.

[0037] like Figure 3 As shown, further, the filter tank body 2 is provided with a cover door 21 at one end of the bag filter assembly 3, and the cover door 21 is connected to the filter tank body 2 through a threaded seal.
