Description

Technical Field

[0001] This utility model relates to the field of peony deep processing technology, and in particular to a solid-liquid separation device for organic Danfeng peony extract. Background Technology

[0002] Currently, peonies are being cultivated on a large scale as an economic crop in places like Luoyang and Heze. Studies have shown that the root bark, petals, and seeds of organic Danfeng peonies are rich in various active substances such as paeonol, paeonol glycosides, and psoralen. These active substances not only possess a natural fragrance but also exhibit excellent antioxidant and anti-aging effects. Current extraction processes for these active substances include pulping, solid-liquid separation (filtration), and extraction. The solid-liquid separation device is used to separate particulate matter from the pulp.

[0003] See attached document Figure 1 The existing solid-liquid separation device includes a filter hopper 1, inside which are installed three layers of filter screens 3: the bottom layer has a small mesh count, the next layer has a moderate mesh count, and the final layer has a large mesh count. (See attached diagram.) Figure 2 The filter hopper 1 has multiple flanges 2 for supporting the filter screen 3. The filter screen 3 consists of a steel wire mesh 32 and a metal sheet filter frame 31 surrounding the steel wire mesh 32. There are two main problems: First, the filter screen 3 needs to be cleaned regularly. Due to the obstruction of the flanges 2, the lower filter screen 3 needs to be bent to be placed or removed, resulting in unevenness and affecting the filtration effect. Second, the filter screen 3 also needs to be replaced regularly. The steel wire mesh 32 is readily available, but the metal sheet filter frame 31 is a non-standard part that needs to be manufactured, indirectly increasing production costs. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model discloses a solid-liquid separation device for organic peony extract, which adopts the following technical solution:

[0005] A solid-liquid separation device for organic peony extract includes a filter bucket and multiple filter screens. The filter bucket has multiple flanges for supporting the filter screens. The filter screens are composed of steel wire mesh and filter frames surrounding the steel wire mesh. The steel wire mesh has magnetic properties, and the filter frames are composed of two rubber magnetic strip frames. The steel wire mesh is held between the two rubber magnetic strip frames by magnetic attraction.

[0006] In a further improved technical solution, the flange is magnetically attracted, and the filter frame is magnetically attracted to the flange.

[0007] To further improve the technical solution, the filter bucket has magnetic attraction, and the flange is welded inside the filter bucket.

[0008] To further improve the technical solution, a stepped structure for clamping the steel wire filter screen is provided on the rubber magnetic strip frame.

[0009] To further improve the technical solution, the filter bucket is a rectangular filter bucket, and the rubber magnetic strip frame is a rectangular rubber magnetic strip frame.

[0010] To further improve the technical solution, the filter bucket is a circular filter bucket, and the rubber magnetic strip frame is an annular rubber magnetic strip frame.

[0011] The beneficial effects of implementing the above technical solution are as follows:

[0012] Compared to the metal sheet metal filter frames in the background technology, the rubber magnetic strip frames are magnetic and flexible, making it easy to remove the filter screen from the filter basket when cleaning. Especially when replacing the filter screen, there's no need to make a metal sheet metal filter frame; simply magnetically attach the cut wire mesh between two rubber magnetic strip frames, saving time and effort. More importantly, the rubber magnetic strip frames are reusable, reducing production costs.

[0013] In addition, the rubber magnetic strip frame can completely fit onto the flange to form a sealed structure, preventing slurry leakage and improving the filtration effect. Attached Figure Description

Those skilled in the art should understand that these embodiments are merely used to explain the technical principles of this utility model and are not intended to limit the scope of protection of this utility model. It should be noted that in the description of this utility model, terms such as "front," "rear," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, it should not be construed as a limitation of this utility model. It should also be noted that in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] See attached document Figure 1 A solid-liquid separation device for organic peony extract includes a filter hopper 1 and three filter screens 3. Three flanges 2 are arranged inside the filter hopper 1 to support the filter screens 3. Each filter screen 3 consists of a steel wire mesh 32 and a filter frame surrounding the steel wire mesh 32. For layer-by-layer filtration, the lower filter screens have a small mesh count, the next lower filter screen has a moderate mesh count, and the next lower filter screen has a large mesh count. The structure and function are described in detail below.

[0023] See attached document Figure 3 To address the problems in the background art, the wire mesh filter 32 is magnetic, and the filter frame consists of two rubber magnetic strip frames 33, with the wire mesh filter 32 held between the two rubber magnetic strip frames 33 by magnetic attraction. In this embodiment, the filter hopper 1 is a rectangular filter hopper, the rubber magnetic strip frames 33 are rectangular rubber magnetic strip frames, the filter hopper is made of low-carbon steel and has magnetic attraction; the flange 2 is also made of low-carbon steel and has magnetic attraction, and the flange 2 is welded inside the filter hopper 1.

[0024] Rubber magnetic strips are widely used in refrigerator door seals, writing boards, toys, and other fields. Unlike ordinary rubber strips, rubber magnetic strips contain 85-92% ferrite magnetic powder and 5-9% CPE. After being magnetized, the rubber magnetic strip frame 33 not only has a certain degree of flexibility but also has strong magnetism, which allows it to hold the steel wire filter screen 32 between two rubber magnetic strip frames 33 by magnetic attraction, forming a complete filter screen 3.

[0025] See attached document Figure 4To improve the clamping effect on the wire mesh 32, each rubber magnetic strip frame 33 is provided with a stepped structure 331 for clamping the wire mesh 32.

[0026] See attached document Figure 5 Compared to the metal sheet filter frame 31, the rubber magnetic strip frame 33 applies relatively less tension to the wire mesh filter 32. However, the rubber magnetic strip frame 33 is more flexible, making it easy to remove the filter screen 3 from the filter hopper 1 when cleaning it. Especially when replacing the filter screen 3, there is no need to fabricate a metal sheet filter frame 31; simply magnetically attach the cut wire mesh filter 32 between the two rubber magnetic strip frames 33, saving time and effort. More importantly, the rubber magnetic strip frame 33 is reusable, reducing production costs.

[0027] Furthermore, existing filter screens 3 are prone to forming gaps between the metal sheet filter frame 31 and the flange 2, allowing slurry to leak out and affecting the filtration effect. For this solid-liquid separation device, since the rubber magnetic strip frame 33 has magnetic attraction not only to the steel wire filter screen 32 but also to the filter hopper 1 and the flange 2, it can completely adhere to the flange 2 to form a sealed structure, preventing slurry leakage and improving the filtration effect.

[0028] See attached document Figure 6 The filter hopper 1 can also be a circular filter hopper, and correspondingly, the rubber magnetic strip frame 33 can also be a ring-shaped rubber magnetic strip frame.

[0029] The parts not detailed herein are prior art. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of protection of which is defined by the appended claims and their equivalents.
