[0037] Example 2:
[0038] Reference Figure 2 and Figure 4 The cleaning mechanism 5 includes a threaded rod 501, which is rotatably connected to the top of the inner surface of the filter cylinder 3 via a bearing. A threaded sleeve 502 is threadedly connected to the outer surface of the threaded rod 501. A support rod 503 is fixedly connected to the bottom of the threaded sleeve 502.

By setting a sliding rod 12 and a sliding sleeve 13, the movement of the threaded sleeve 502 can be guided and limited.
[0042] The implementation principle of this utility model is as follows: When it is necessary to separate the fermentation liquid, the fermentation liquid to be separated is put into the separation cylinder 1 through the feed pipe. First, the particulate matter in the fermentation liquid is filtered through the filter screen 4. The filtered fermentation liquid falls onto the surface of the separation membrane 7 below the filter screen 4. The fermentation liquid is separated through the separation membrane 7 and finally discharged through the discharge pipe. When it is necessary to clean the surface of the filter screen 4, the handle 508 is rotated. The handle 508 drives the rotating shaft 507 to rotate. The rotating shaft 507 drives the active helical gear 506 to rotate. The active helical gear 506 drives the driven helical gear 505 to rotate. The driven helical gear 505 drives the threaded rod 501 to rotate. The threaded rod 501 drives the threaded sleeve 502 to move. The threaded sleeve 502 drives the support rod 503 to move. The support rod 503 drives the brush plate 504 to move. The brush plate 504 cleans the surface of the filter screen 4 to avoid clogging of the filter screen 4 and improve the filtration effect.
[0043] When the separation membrane 7 is damaged and needs to be replaced, rotate the sealing cover 2 to remove it from the top of the separation cylinder 1, take out the filter cylinder 3, pull the pull block 803 to both sides, the pull block 803 drives the limiting rod 802 to move, so that the limiting rod 802 disengages from the limiting hole 804, then move the limiting frame 6 downward to remove the limiting frame 6 and the separation membrane 7. At this time, the filter screen 4 can also be removed from the inner surface of the filter cylinder 3 for cleaning or replacement. Then, install the new separation membrane 7 at the bottom of the filter cylinder 3 through the limiting frame 6, release the pull block 803, and push the limiting rod 802 to move through the action of the compression spring 11, so that the limiting rod 802 is inserted into the limiting hole 804 to complete the fixation. Finally, seal the sealing cover 2 on the top of the separation cylinder 1. This method is convenient for disassembling and assembling the separation membrane 7, and can quickly replace it when it is damaged. It is easy to use.
[0044] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
