[0001] The utility model relates to the technical field of plant extraction, in particular to a high-efficiency filtering device for preparing plant extracts. Background Art

[0002] Plant extracts are products made from plants as raw materials. According to the needs of the final product, they are extracted through a physical and chemical extraction and separation process to obtain and concentrate one or more active ingredients in the plant without changing the structure of the active ingredients. The application range of plant extracts is now very wide. In addition to the traditional use in traditional Chinese medicine products, as people's trust and dependence on natural products gradually increase, a large part of plant extracts have been used in the field of health care products and food ingredients. In addition, plant extracts have been used in cosmetics and feed in recent years.

[0003] In order to ensure the quality of the final extract, it is necessary to separate the plant debris and juice in the extract. The current common method is to filter the extract with a filter. However, as the filtration progresses, a large area of ​​the filter surface will be covered by plant debris, and the liquid can only flow by gravity. The slowdown in filtration speed will seriously affect the filtration efficiency, thereby affecting the preparation of plant extracts. Utility Model Content

[0024] See also Figure 1-Figure 5 As shown, the driving assembly includes a rotating groove 10 opened on the inner side of the filter barrel 1 at the filter plate 8, a rotating support ring 12 is rotatably installed in the rotating groove 10 through a rotating bearing 13, the filter plate 8 is fixed in the rotating support ring 12, and a driven gear ring 14 is connected to the outer side of the rotating support ring 12. A driving box 15 is provided on the outer side of the filter barrel 1, and a driving motor 16 is provided in the driving box 15. Channels connected to the rotating groove 10 are opened on the side walls of the driving box 15 and the filter barrel 1. A reduction gear set 17 is provided in the driving box 15, and the rotating shaft of the driving motor 16 is connected to the driven gear ring 14 through the reduction gear set 17.

[0025] An array of sliding sealing rings 11 is provided between the rotating support ring 12 and the inner wall of the filter barrel 1 .

[0026] As an optimization solution of the utility model, the driven motor 16 drives the driven gear ring 14, the rotating support ring 12 and the filter plate 8 to rotate through the reduction gear set 17, so that the filter plate 8 and the liquid above produce relative movement, thereby reducing the sedimentation and blockage phenomenon caused in the static state. At the same time, the sliding sealing ring 11 can prevent liquid from entering, thereby ensuring safe operation.

[0027] See also Figure 1-Figure 6 As shown, the back-drawing anti-blocking structure includes a transition chamber 20 opened in the inner wall of the filter barrel 1, one side of the transition chamber 20 is connected to the filter barrel 1, and an air filter 21 is provided at the connection, one end of the suction pipe 19 is arranged in the transition chamber 20, an air intake pipe 22 is fixedly inserted in the filter barrel 1, one end of the air intake pipe 22 is connected to the transition chamber 20, the other end of the air intake pipe 22 is arranged outside the filter barrel 1, and an air filter head 23 is connected to the end of the air intake pipe 22 located outside the filter barrel 1, and an air intake valve 9 is provided on the air intake pipe 22.

[0028] As an optimization scheme of the present utility model, the air intake valve 9 is used to control the on and off of the air intake pipe 22, thereby controlling the air pressure in the filter barrel 1. When in use, the vacuum pump 18 draws out the gas in the filter barrel 1 through the suction pipe 19, so that the air pressure in the upper and lower parts of the filter plate 8 decreases. When the air intake valve 9 is opened, the external air enters the filter barrel 1 after passing through the air intake pipe 22 and the transition chamber 20, so that the air pressure below the filter plate 8 is greater than the air pressure above, so that the atmospheric pressure pushes the liquid and air upward, and pushes the substances blocked in the filter holes of the filter plate 8 upward, thereby preventing the filter holes from being blocked. The air filter head 23 and the air filter 21 can filter the gas respectively to prevent dust and external particulate matter from entering the filter barrel 1.

[0029] See also Figure 1-Figure 2 As shown, a sealing cover 3 is provided on the feed port 2, a sealing ring is provided inside the sealing cover 3, and buckle assemblies 4 are provided on both sides of the feed port 2 respectively.

[0030] As an optimization solution of the present utility model, the sealing cover 3 can maintain the sealing of the feed port 2. After the sealing cover 3 is fixed by the buckle assembly 4, it can prevent the air pressure change from affecting the sealing cover 3.

[0031] The use process of this utility model:

[0032] First, open the sealing cover 3, pour the liquid mixture to be filtered into it, then close the feed port 2, and fix the sealing cover 3 with the buckle assembly 4, and then start the driving motor 16 and the vacuum pump 18. The driving motor 16 drives the filter plate 8 to rotate at a constant speed, thereby preventing the liquid from being stationary and reducing blockage. At the same time, the vacuum pump 18 extracts the air under the filter plate 8, so that the air pressure is reduced and the filtration of the liquid is accelerated. As the liquid is filtered and flows down, the air pressure in the filter barrel 1 above the filter plate 8 is gradually reduced, so that the air pressure is less than the atmospheric pressure. After filtering for a period of time, close the suction pipe 19, and then open the air inlet valve 9. The atmospheric pressure sends the gas from the air inlet pipe 22 to the lower half of the filter barrel 1. At this time, the upper half of the filter barrel 1 is still in a low pressure state, and the air pressure below is greater than the air pressure above, so that the gas and liquid are pushed upward from the filter holes of the filter plate 8 to push out the blockage, and then close the air inlet valve 9 and start the suction pipe 19 to continue filtering, thereby preventing the filter holes from being blocked and accelerating the filtration;

[0033] After the filtration is completed, the air inlet valve 9 is opened again to restore the air pressure in the filter barrel 1 to atmospheric pressure, and then the discharge valve 7 is opened to discharge the filtered liquid through the discharge pipe 6.

Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
