[0046] Working principle: the aluminum liquid to be removed flows into the connection pipe 28 along the inside of the L-shaped liquid inlet groove 27, and flows into between the retaining ring 29 and the rotating disk 26. The aluminum liquid passes through the first filter screen 210 and flows into the inside of the second rectangular groove 22, and flows into the inside of the fine filter box 43 along the inside of the output pipe 23. The fine filter box 43 is located below the second rectangular groove 22. When the aluminum liquid flows into the fine filter box 43, it passes through the ceramic filter membrane 410, and flows along the inside of the built-in piston frame plate 48 to the top of the built-in piston frame plate 48, and flows along the inside of the built-in connecting pipe 47 to the inside of the third rectangular groove 44 for storage, and is discharged along the inside of the liquid outlet pipe 46;

[0047] The operation of the driving motor 24 drives the rotating disk 26 to rotate through the rotating shaft 25, and the rotation of the rotating disk 26 drives the annular sleeve 211 to rotate. The filter holes on the surface of the first filter screen 210 filter the aluminum liquid, and the filtered debris accumulates on the surface of the first filter screen 210. As the first filter screen 210 rotates, under the action of the first mounting groove and the blocking action of the inclined baffle 216, as the annular sleeve 211 rotates, the filtered debris rises to a high place as the first filter screen 210 rotates, and when it is above the conveying hopper 212, the filtered debris falls onto the conveying hopper 212 under the action of the inclination of the inclined baffle 216, which is conducive to filtering the debris in the aluminum liquid and causing the filtered debris to automatically fall onto the conveying hopper 212 for collection;

[0048] The conveying hopper 212 is inclined, and the annular sleeve 211 drives the lower arc block 310 to rotate when rotating. The rotation of the lower arc block 310 makes the upper arc block 38 slide against the arc end of the lower arc block 310. The shapes of the upper arc block 38 and the lower arc block 310 can be referred to Figure 8 As shown, when the upper arc block 38 slides from one end of the arc of the lower arc block 310 to the surface of the lower arc block 310, the second lower connecting rod 39 moves upward, and the movement of the second lower connecting rod 39 drives the longitudinal insertion rod 34 to move upward through the top cross bar 35, thereby causing the optical axis 32 to drive the conveying hopper 212 to rotate clockwise with the auxiliary rotating shaft 214 as the axis. When the upper arc block 38 slides out from the surface of the lower arc block 310, the second lower connecting rod 39 moves downward quickly under the action of the appearance of the upper arc block 38 and the lower arc block 310. The positions of the upper arc block 38 and the lower arc block 310 in this process can be referred to Figure 8 As shown, the top cross bar 35 moves vertically back and forth, causing the conveying hopper 212 to rotate rapidly counterclockwise, thereby shaking the conveying hopper 212, so that the debris dropped from the conveying hopper 212 flows along the inside of the conveying hopper 212 into the inside of the first rectangular groove 21;

[0049] When the top cross bar 35 moves downward, the first lower connecting rod 36 drives the isosceles pressure block 37 to move downward quickly, and then the surface of the first filter screen 210 is hammered by the isosceles pressure block 37, so that the debris adhering to the surface of the first filter screen 210 falls into the inside of the conveying hopper 212, thereby ensuring the effect of filtering and removing impurities from the aluminum liquid through the first filter screen 210;

[0050] The number of the lower arc-shaped blocks 310 and the first filter screen 210 is the same, and the isosceles pressure block 37 can accurately hammer on the first filter screen 210 only when the upper arc-shaped block 38 descends rapidly. Although the upper arc-shaped block 38 slides to another lower arc-shaped block 310, the isosceles pressure block 37 moves a short distance on the surface of the first filter screen 210, the movement process will not cause damage to the first filter screen 210.

[0051] When the aluminum liquid filtered by the first filter screen 210 flows into the interior of the fine filter box 43 along the interior of the output pipe 23, the two ceramic filter membranes 410 can further remove tiny impurities in the aluminum liquid to ensure the purity of the aluminum liquid. During the vertical reciprocating movement of the top cross bar 35, the third lower connecting rod 42 moves vertically reciprocatingly. When the third lower connecting rod 42 moves, it drives the built-in piston frame plate 48 to slide inside the fine filter box 43. When the built-in piston frame plate 48 moves upward, the ceramic filter membrane 410 slides against the surface of the triangular scraper strip 416. Due to the tilted setting of the ceramic filter membrane 410, the transverse sealing plug plate 415 exerts a force on the connecting steel wire 412, and under the action of the gravity of the counterweight block 413, the triangular scraper strip 416 always exerts a mutual force on the ceramic filter membrane 410, thereby scraping off the impurities adhering to the surface of the ceramic filter membrane 410, further ensuring the effect of the ceramic filter membrane 410 on filtering tiny impurities in the aluminum liquid, which is beneficial to filtering tiny impurities in the aluminum liquid, and scraping off the impurities adhering to the surface of the ceramic filter membrane 410, thereby ensuring the purity of the aluminum liquid;

[0052] Since the temperature of the aluminum liquid is relatively high, the aluminum liquid flowing inside the impurity removal box 1 can make the impurity removal box 1 have a relatively high temperature, so that the flow speed of the aluminum liquid is within a certain range, and an insulation layer can be wrapped on the surface of the impurity removal box 1 to maintain the temperature of the aluminum liquid during the impurity removal process, so as to avoid the deterioration of the fluidity of the aluminum liquid due to the decrease in temperature and affect the impurity removal effect;

[0053] Under the restriction of the limiting plate 41 and the U-shaped bending plate 31, the top cross bar 35 can always be in a vertical moving state, thereby ensuring the use effect of the device;

[0054] The side receiving bucket 411 is provided to prevent the aluminum liquid from flowing along the gap between the transverse sealing plug plate 415 and the fine filter box 43, so as to facilitate the collection of the aluminum liquid flowing out from the inside of the transverse groove sealing slot 414. After the aluminum liquid is removed from impurities, the aluminum liquid collected in the side receiving bucket 411 can be discharged by opening the first valve 417 and the second valve 418, and the tiny impurities and residual aluminum liquid filtered in the fine filter box 43 can be discharged.

[0055] In the present invention, each key component has excellent high temperature resistance and can operate stably and reliably in the high temperature environment of the aluminum liquid.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
