The working box 1 comprises a working space 3, the cleaning mechanism 4 and the fixed plate 12 are respectively arranged in the working space 3, the cleaning mechanism 4 is arranged above the fixed plate 12, a plurality of filter holes 13 are opened on the fixed plate 12, the second filter screen 14 is fixed in the filter holes 13, the liquid outlet pipe 17 is fixed at the bottom of the working box 1 and communicates with the working space 3, and the cover body 18 is snapped into the liquid outlet pipe 17.

[0021] The graphite liquid is introduced into the working box 1 through the feed pipe 2, and then filtered for the first time through the impurity removal mechanism 4. The filtered graphite liquid flows into the fixed plate 12, and then filtered for the second time through the second filter screen 14 in the filter hole 13, and the graphite liquid filtered for the second time is stored at the bottom of the working box 1. The impurities in the graphite liquid are filtered more cleanly through the two filtrations, thereby improving the quality.

[0022] The impurity removal mechanism 4 includes a first filter screen 41, a handle 42, a limit plate 43 and a sealing sleeve 44. The working box 1 is provided with a first limit groove 5 connected to the working space 3, and the inner wall of the working box 1 is provided with a second limit groove 6 corresponding to the first limit groove 5. The handle 42 is fixedly connected to the limit plate 43, and the sealing sleeve 44 is sleeved on both ends of the limit plate 43. The limit plate 43 passes through the first limit groove 5 and the working space 3 in sequence and extends into the second limit groove 6.

[0023] By pouring graphite liquid into the feed pipe 2 and then flowing it into the working space 3, the graphite liquid is accumulated on the limit plate 43, and the impurities in the graphite liquid are filtered through the first filter screen 41. The sealing sleeve 44 is used to prevent the impurities that have not been filtered from flowing to the bottom of the working box 1 through the gaps between the two ends of the limit plate 43 and the first limit groove 5 and the second limit groove 6. The impurities are placed on the first filter screen 41, and the filtered graphite liquid continues to flow to the bottom of the working box 1, thereby filtering the graphite liquid. After the graphite liquid is filtered, the limit plate 43 is removed from the working box 1 through the handle 42, and the impurities on the first filter screen 41 are poured out, and the limit plate 43 is re-inserted into the working box 1 through the first limit groove 5, so that the first filter screen 41 is not easily blocked, resulting in poor filtering efficiency when the graphite liquid is filtered next time.

[0024] Two corresponding fixing grooves 7 are formed on the bottom of the limiting plate 43, and triangular blocks 8 are respectively hinged at both ends of the limiting plate 43. The two triangular blocks 8 are respectively placed in the two fixing grooves 7.

[0026] The working box 1 is provided with a storage slot 15, and an observation window 16 is provided in the storage slot 15;

[0027] The observation window 16 allows the filtering condition of the graphite liquid to be observed after the graphite liquid is poured into the working box 1 .

[0028] An annular groove 19 is provided on the cover 18, and an annular protrusion 20 is provided inside the liquid outlet pipe 17. The cover 18 extends into the liquid outlet pipe 17 and the annular protrusion 20 is engaged with the annular groove 19.

[0029] By pulling the cover 18 out of the liquid outlet pipe 17 , the annular groove 19 and the annular protrusion 20 are separated, so that the filtered graphite liquid flows out through the liquid outlet pipe 17 .

[0030] Working principle: first, the graphite liquid is poured into the working box 1 through the feed pipe 2, and then the graphite liquid poured into the working box 1 flows into the limit plate 43, and then the water-ink liquid is filtered for the first time through the first filter screen 41, and then the impurities are retained in the first filter screen 41, and the filtered graphite liquid continues to flow downward until it is placed on the fixed plate 12, and then the graphite liquid that has been filtered once is filtered for the second time through the second filter screen 14 on the fixed plate 12, and then the graphite liquid that has been filtered twice is accumulated at the bottom of the working box 1, and then the cover body 18 is pulled out from the liquid outlet pipe, and then the filtered graphite liquid flows out from the liquid outlet pipe 17, and then the limit plate 43 is pulled outward by the handle 42, so that the triangular block 8 rotates, and then the triangular block 8 is placed in the fixed groove 7, and then the limit plate 43 is pulled out from the working box 1, and then the impurities placed on the first filter screen 41 are poured out and reinserted into the working box 1.
