[0017] In order to improve the filtering effect, ensure the color of the vinegar, and improve the flavor of the vinegar, the three-way electromagnetic valve 13 is connected with the inlet end of a fine filter box 15, two layers of activated carbon filter layers 16 are inserted into the fine filter box 15 through track clamping, and the discharge end of the fine filter box 15 is connected with the discharge pipe.

[0018] In order to facilitate the disassembly, cleaning and replacement of the activated carbon filter layers 16, a box door is arranged on one side of the fine filter box 15, and a sealing strip is arranged between the box door and the fine filter box 15.

[0019] In order to facilitate the cleaning of impurities while filtering, the filter plates 2 are in a conical structure.

[0020] In order to facilitate the cleaning of more impurities on the filter plates 2, a cleaning door is arranged at the position corresponding to the filter plates 2 of the filter tank 1, and a sealing strip is arranged between the cleaning door and the filter tank 1 to avoid leakage of the vinegar during use.

[0021] In order to facilitate the observation of the amount of vinegar in the sedimentation tank 18, a liquid level meter 20 is connected to the sedimentation tank 18.

[0022] In order to improve the filtering effect of the vinegar, the diameters of the filter holes of the filter plates 2 arranged from top to bottom gradually decrease. It should be noted that in the embodiment, two filter plates 2 are arranged, the diameter of the filter holes arranged on the upper filter plate 2 is greater than the diameter of the filter holes arranged on the lower filter plate 2.

[0023] It should be noted that in the embodiment, the number of the sedimentation tanks 18 can be set according to the actual production, and the filter tank 1 can realize continuous production.

[0024] The working process of the embodiment is as follows:

[0025] In the production process of vinegar, when filtration is needed, the vinegar is put into the original vinegar tank 8, the first valve 11 is opened and the liquid pump 10 is started to draw the vinegar from the vinegar inlet pipe into the feed pipe 9 and then into the annular spray pipe 3 and sprayed from the spray head 4. The vinegar falls on the upper filter plate 2 and then on the lower filter plate 2 after filtration and finally falls on the bottom of the filter tank 1. At the same time, the motor 6 is started to rotate the rotating shaft 5 and then drive the scraper 7 to scrape the upper surface of the filter plate 2 to avoid the filter plate 2 being blocked by impurities during the filtration process. Then the three-way electromagnetic valve 13 is controlled to close one end of the drain pipe 14 and open the other two ends, so that the filtered vinegar enters the fine filter box 15. After the vinegar is filtered by the activated carbon filter layer 16, it enters the discharge pipe. One of the third valves 19 on the branch pipes is controlled to be opened, the conveying pump 17 is started to run, and the fine-filtered vinegar is conveyed to the corresponding settling tank 18. The liquid level meter 20 is observed. After the settling tank 18 is filled, the third valve 19 on the other branch pipe is controlled to be opened, so that the vinegar enters the corresponding settling tank 18. After the vinegar in the settling tank 18 is settled for a period of time, the supernatant can be drawn.

[0026] When the filtration is stopped and the filter tank 1 needs to be cleaned, the impurities on the corresponding filter plate 2 and scraper 7 are removed by opening the cleaning door. Then the cleaning door is closed again, the second valve 12 is controlled to be opened, the first valve 11 is controlled to be closed, the water source is connected, and the liquid pump 10 is started to run, so that the clean water is sprayed from the spray head 4 of the annular spray pipe 3.
