Technical Field

[0001] The utility model relates to the technical field of perilla seed oil processing, in particular to a fine filtering device for perilla seed oil processing. Background Technique

[0002] Perilla, also known as red perilla, red perilla, and fragrant perilla, is an annual herb of the Labiatae family and is a traditional medicinal and edible plant. As the name implies, perilla seed oil is processed from perilla seeds.

[0003] In the process of current production and processing of perilla seed oil, it is necessary to finely filter the perilla seed oil to remove impurities in the oil. When the existing fine filtering device is actually used, the oil is often introduced into the filtering cylinder, and then filtered by a filter mesh plate. However, in the actual filtering process, the holes on the filter mesh plate will be blocked by impurities, thus affecting the oil passing efficiency and further affecting the overall efficiency of filtering the oil. Therefore, we propose a fine filtering device for perilla seed oil processing. Content of the Utility Model

A conduit is fixed to the outer end of the air pump, and the outer end of the conduit is communicated with the tail end of the hollow shaft through a rotary joint.

[0007] By adopting the above technical solution, the oil to be filtered is first introduced into the inner cavity of the feed hopper, so that the oil enters the inner cavity of the filter cylinder and is filtered through the filter mesh plate.

At the same time, the air pump is used to generate gas that enters the hollow shaft, then enters the hollow plate, and then blows back the filter mesh plate along the holes, thereby avoiding blockage of the filter mesh plate and affecting the oil passing speed, and further facilitating the avoidance of the situation where the filtering efficiency is affected due to blockage.

[0008] As a preferred embodiment of the present invention, the tail end of the feed hopper is fixedly communicated with a short pipe, and the short pipe movably penetrates through the filter cylinder and is rotationally communicated with a horizontally arranged cloth pipe.

[0013] As a preferred embodiment of the present invention, a support is fixedly connected to the lower side of the outer wall of the filter cylinder.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] A fine filtration device for processing perilla seed oil according to the technical solution of the present application rotates through a hollow shaft driven by gear transmission, thereby driving a scraper to scrape, so that impurities accumulated on the surface can be scraped and moved to the edge of the filter mesh plate. At the same time, the method of gas back blowing is used to blow from the bottom of the filter mesh plate, so that the blocked impurities are blown away from the holes of the filter mesh plate, which is beneficial to avoid the situation that the filtration is affected due to blockage, and thus improves the filtration efficiency;

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: a fine filtration device for processing perilla seed oil, including a filter cylinder 1, a feed hopper 12 is fixedly communicated with the middle of the top of the filter cylinder 1, and an arc-shaped filter mesh plate 15 is fixed in the inner cavity of the filter cylinder 1;

[0026] The bottom of the filter cartridge 1 is penetrated by a hollow shaft 2. The hollow shaft 2 movably penetrates through the filter screen plate 15 and is fixedly connected to a scraper 21 arranged in contact with the filter screen plate 15. The outer wall of the hollow shaft 2 is fixedly communicated with a hollow plate 24. The hollow plate 24 is arranged in contact with the bottom of the filter screen plate 15. A plurality of uniformly distributed holes 27 are formed in the top of the hollow plate 24. The lower side of the outer wall of the hollow shaft 2 is fixedly sleeved with a first gear 22. The outer wall of the first gear 22 is engaged with a second gear 23. The second gear 23 is fixed to the outer end of the transmission shaft of the servo motor. The servo motor is fixed to the bottom of the filter cartridge 1. One side of the bottom of the filter cartridge 1 is fixed with an air pump 25. The outer end of the air pump 25 is fixed with a conduit, and the outer end of the conduit is communicated with the tail end of the hollow shaft 2 through a rotary joint;

[0027] During actual use, first, the oil to be filtered is introduced into the inner cavity of the feed hopper 12, so that the oil enters the inner cavity of the filter cartridge 1 and is filtered through the filter screen plate 15. During the filtering process, the servo motor drives the second gear 23 to rotate, thereby driving the first gear 22 to rotate, which can drive the hollow shaft 2 to rotate, and then drive the scraper 21 to scrape the impurities accumulated on the surface of the filter screen plate 15, so that the impurities move along the arc of the surface of the filter screen plate 15 towards the edge, avoiding sedimentation on the top of the filter screen plate 15 and affecting the filtering effect. At the same time, cooperate with the air pump 25 to generate gas and enter the hollow shaft 2, then enter the hollow plate 24, and then blow back the filter screen plate 15 along the holes 27, thereby avoiding the filter screen plate 15 from being blocked and affecting the oil passing speed, and further avoiding the situation of affecting the filtering efficiency due to blockage.

[0028] Furthermore, the lower side of the outer wall of the filter cartridge 1 is fixedly connected with a bracket 11. The setting of the bracket 11 makes the device have a certain height and ensures the overall stability of the device.

[0029] Even further, one side of the bottom of the filter cartridge 1 is fixedly communicated with a discharge pipe. The setting of the discharge pipe enables the filtered oil to be discharged.

[0030] It is worth introducing that an outlet is formed in one side wall of the filter cartridge 1 and is arranged corresponding to the edge of the filter screen plate 15. A cover plate 16 is detachably fixed to the outer wall of the outlet. Thus, by opening the cover plate 16 and using the scraper 21 to agitate the impurities to move, the impurities can be taken out along the outlet, so the operation is highly convenient.

[0031] It should be noted that a wedge-shaped block is fixed to the bottom of the filter cartridge 1. The hollow shaft 2 movably penetrates through the wedge-shaped block. The setting of the wedge-shaped block enables the oil to be guided to the discharge pipe, thereby avoiding the accumulation of oil at the bottom of the inner cavity of the filter cartridge 1.

[0032] Such as Figure 1 and 2, as shown in Figure 4; the tail end of the feed hopper 12 is fixedly connected with a short pipe, and the short pipe movably penetrates through the filter cylinder 1 and is rotationally connected with a horizontally arranged cloth pipe 13. A plurality of uniformly distributed oil outlet holes 14 are formed in the bottom of the cloth pipe 13. A rotating shaft 26 is fixed to the top of the hollow shaft 2. The top of the rotating shaft 26 and the corresponding position at the bottom of the cloth pipe 13 are fixedly connected. The rotating shaft 26 and the short pipe are concentrically arranged. By rotating the hollow shaft 2, the rotating shaft 26 can be driven to rotate, and the cloth pipe 13 can be driven to rotate, so as to realize uniform cloth feeding, avoid the imported oil liquid concentrating on a local part of the filter mesh plate 15, and further avoid the accumulation of impurities in a local part, improving the comprehensiveness and sufficiency of the use of the filter mesh plate 15.

[0033] The implementation principle of a fine filtration device for perilla seed oil processing in this application is as follows: during actual use, first, the oil liquid to be filtered is introduced into the inner cavity of the feed hopper 12, and then the oil liquid enters the inner cavity of the filter cylinder 1 and is filtered through the filter mesh plate 15. During the filtering process, the servo motor drives the second gear 23 to rotate, thereby driving the first gear 22 to rotate, which can drive the hollow shaft 2 to rotate, and then the scraper 21 can be driven to scrape the impurities accumulated on the surface of the filter mesh plate 15, so that the impurities move along the curvature of the surface of the filter mesh plate 15 towards the edge, avoiding accumulation on the top of the filter mesh plate 15 and affecting the filtering effect. At the same time, the air pump 25 is used to generate gas and enter the hollow shaft 2, then enter the hollow plate 24, and then the filter mesh plate 15 can be blown back along the holes 27, so as to avoid the blockage of the filter mesh plate 15 and affect the oil passing speed, and further avoid the situation of affecting the filtering efficiency due to blockage. At the same time, by rotating the hollow shaft 2, the rotating shaft 26 can be driven to rotate, and the cloth pipe 13 can be driven to rotate, so as to realize uniform cloth feeding, avoid the imported oil liquid concentrating on a local part of the filter mesh plate 15, and further avoid the accumulation of impurities in a local part, improving the comprehensiveness and sufficiency of the use of the filter mesh plate 15.
