[0036] The utility model is further described in conjunction with the following embodiments.

[0037] Example 1.

[0038] like Figure 1-4 As shown, a Chinese medicine liquid raw material filtering device comprises a filtering box body 1, an upper filter screen 2 and a lower filter screen 3 are detachably installed inside the filtering box body 1, an upper positioning diverter block 4 is fixedly installed at the center of the upper filter screen 2, a lower positioning diverter block 5 is fixedly installed at the center of the lower filter screen 3, a driving component 6 is fixedly installed below the lower positioning diverter block 5, a rotating shaft 7 is fixedly installed at the output end of the driving component 6, an end of the rotating shaft 7 away from the driving component 6 passes through the lower positioning diverter block 5, and is rotatably installed on the upper positioning diverter block 4, and a filter hole cleaning mechanism 8 is fixedly installed on the rotating shaft 7.

[0039] The present application is used for filtering raw materials of traditional Chinese medicine liquid. First, the raw materials of traditional Chinese medicine liquid enter through the feed port above the side wall of the filter box 1, the raw materials of traditional Chinese medicine liquid are contained in the filter box 1, and then preliminary filtration is carried out through the upper filter screen 2, and then secondary filtration is carried out through the lower filter screen 3. The driving component 6 drives the rotating shaft 7 to rotate on the lower positioning diverter block 5 and the upper positioning diverter block 4, and the rotating shaft 7 drives the filter hole cleaning mechanism 8 to clean the filter holes on the upper filter screen 2 and the lower filter screen 3. The upper positioning diverter block 4 and the lower diverter positioning block can prevent dead corners in the filtration of the raw materials of traditional Chinese medicine liquid.

[0040] The filter hole cleaning mechanism 8 includes a plurality of positioning arms 81, which are vertically mounted on the side of the rotating shaft 7. A plurality of positioning columns 82 are mounted above and below the positioning arms 81. A movable groove 83 is provided at one end of the positioning column 82 away from the positioning arm 81, and a telescopic cleaning column 84 is elastically mounted inside the movable groove 83.

[0041] The filter hole cleaning mechanism 8 positions several positioning columns 82 in a row through the positioning arm 81, and realizes the plug-in cleaning of the filter holes on the upper filter 2 and the lower filter 3 through the elastic extension and contraction of the telescopic cleaning column 84 inside the movable groove 83. The rotation of the rotating shaft 7 drives the positioning arm 81 and the telescopic cleaning column 84 to comprehensively clean the entire upper filter 2 and the lower filter 3 to prevent large-diameter Chinese medicine liquid raw materials from clogging the filter.

[0042] A plurality of filter hole rows 9 are provided in a circular array on the upper filter screen 2 and the lower filter screen 3. The number and position of the filter holes on the filter hole row 9 correspond to the telescopic cleaning column 84.

When the positioning arm 81 drives the telescopic cleaning column 84 to rotate through the filter holes on the upper filter 2 and the lower filter 3, a portion of the inclined guide surface 85 will be inserted into the filter holes on the upper filter 2 and the lower filter 3 due to the elasticity of the spring, thereby cleaning the Chinese medicinal liquid raw materials blocked on the upper filter 2 and the lower filter 3. When the positioning arm 81 drives the telescopic cleaning column 84 to continue rotating, the inclined guide surface 85 will follow the rotation of the telescopic cleaning column 84 and contact with the filter holes to achieve contraction, and then enter the next row of filter holes.

[0044] A conical diversion portion 10 is provided on the upper positioning diversion block 4, a telescopic cylinder 11 is fixedly installed on the top of the filter box 1, the output end of the telescopic cylinder 11 extends to the interior of the filter box 1 and is fixedly installed with a pressure plate 12, a conical groove 13 is provided at the bottom of the pressure plate 12, and the conical groove 13 and the conical diversion portion 10 are movably fitted.

[0045] The upper positioning diversion block 4 allows the Chinese medicinal liquid raw materials entering the upper part of the upper filter screen 2 to fall on the filter holes of the upper filter screen 2 through the conical diversion part 10, avoiding the occurrence of filtering dead corners. The pressing plate 12 can be driven by the telescopic cylinder 11 to press down the Chinese medicinal liquid raw materials to increase the filtering effect. The conical groove 13 corresponds to the conical diversion part 10 to achieve tight downward pressure.

[0046] A lower diverter portion 14 is provided on the lower positioning diverter block 5 , and the top of the lower diverter portion 14 surrounds the rotating shaft 7 .

[0047] The lower positioning diverter block 5 forms a downwardly inclined slope through the lower diverter portion 14, similar to a truncated cone, so that the Chinese medicine liquid raw materials falling on the lower filter screen 3 are drained to prevent the occurrence of filtering dead corners. After filtering by the lower filter screen 3, it is discharged from the discharge port at the bottom of the filter box 1.

[0048] The driving assembly 6 includes a positioning cover 61 , which is fixedly installed below the lower positioning diverter block 5 . A matching driving motor 62 and a reducer 63 are fixedly installed inside the positioning cover, and an output end of the reducer 63 is fixedly connected to the rotating shaft 7 .

[0049] The driving assembly 6 drives the rotating shaft 7 to rotate through the coordinated output of the driving motor 62 and the reducer 63 .

[0050] The utility model cleans the upper filter screen 2 and the lower filter screen 3 simultaneously by rotating the filter hole cleaning mechanism 8, and unclogs the filter holes by movably inserting the elastically mounted telescopic cleaning column 84 inside the filter holes, thereby improving the filtering efficiency of the traditional Chinese medicine liquid.
