Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically a filtration device for collagen preparation. Background Technology

[0002] Collagen is an important biological macromolecule with wide applications in the cosmetics industry, in addition to biological and biomedical research and applications. Its formulation generally involves mixing collagen powder or solution with other solvents and adding other auxiliary substances as needed. During formulation, filtration is usually required to remove large particles, ensuring the homogeneity of the product (solution or emulsion) and improving its stability and safety. Because collagen products generally have high viscosity, large particles easily adhere to the sieve, causing filtration efficiency issues. Cleaning can mitigate this impact; however, common cleaning methods such as rinsing and wiping can easily introduce bacterial contamination. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figure 1-5 As shown, the filtration device for collagen preparation involved in this utility model includes a filter press 1, a filter press cover 2, a support 3, a pressure application unit 4, and a filtration unit 5.

[0021] The filter press 1 is a filling structure with an opening at the top. It has a discharge port 10 at the bottom and a feed port 11 with a valve at the top. The filter press cover 2 is located at the opening at the top of the filter press 1. Its outer diameter is the same as the inner diameter of the filter press 1 and it can slide up and down inside the filter press 1.

[0022] The pressure unit 4 is a linkage structure driven by a hydraulic cylinder, pneumatic cylinder, electric cylinder, or motor, which can drive the filter press cover plate 2 to move up and down.

[0023] To ensure the stability of the trajectory of the filter press cover plate 2 during its up-and-down movement, a number of limiting rods 21 are fixed on the top surface of the filter press cover plate 2, and the upper part of the limiting rods 21 passes through the limiting through holes located on the bracket 3.

[0024] As attached Figure 1 , 3 As shown in Figure 5, the filter unit 5 includes two filter screen assemblies 51, which are arranged vertically inside the filter press tank 1. Each filter screen assembly 51 includes a bottom plate 511, an outer ring 512, a pressure cloth ring 513, and a filter cloth 510.

[0025] The base plate 511 is a circular plate with an upward protrusion 511a in the center. The protrusion is circular and has through holes or through grooves on its surface. The outer side of the protrusion 511a is a ring. An outer ring 512 is provided on the outer side of the base plate 511, and the height of the outer ring 512 is higher than that of the protrusion 511a.

[0026] The filter cloth 510 is disposed above the base plate 511. The pressing ring 513 is box-shaped with a through hole on its top surface. The diameter of the through hole is slightly smaller than the outer diameter of the protrusion. It includes a fixing part 513a and a protruding ring part 513b. The fixing part 513a is annular, and its width is the same as the gap between the protrusion 511a and the outer ring 512. The protruding ring part 513b is provided on the inner side of the upper part of the fixing part 513a. In use, the fixing part 513a of the pressing ring 513 is embedded between the protrusion 511a and the outer ring 512 of the base plate 511. The lower side of the protruding ring part 513b contacts the top surface of the protrusion 511a to fix the filter cloth 510. Furthermore, the pressing ring 513 can be fixed to the base plate 511 by bolts.

[0027] Furthermore, the upper part of the outer ring 512 is provided with several fixing rings for fixing the traction structure Q. The other end of the traction structure of the lower filter assembly 51 is fixed to the lower part of the outer ring of the upper filter assembly 51, and the other end of the traction structure of the upper filter assembly 51 is fixed to the lower part of the filter press cover plate 2. When needed, the filter assembly 51 can be lifted out by lifting the filter press cover plate 2 to replace the filter cloth 510. The traction structure is a stainless steel chain that is easy to clean.

[0028] Furthermore, the filter assembly 51 also includes a rotating blade 514, which includes several blades and a central through hole. A protruding post 514a, located in the center of the base plate 511, passes through the central through hole. The bottom of the protruding post 514, near the base plate 511, has a thickened part J with a height of 5-10 times the thickness of the filter cloth 510. A limit nut M is provided at the top. The rotating blade 514 can rotate during the filtration process, forming turbulence, which can reduce the accumulation of impurities at a certain position on the filter cloth 510 and prevent clogging.

[0029] As attached Figure 2 , 4 As shown, an upper limit groove 12 and a lower limit ring 13 are provided on the inner wall of the filter press 1. The inner diameter of the lower limit ring 13 is smaller than the outer diameter of the filter screen assembly 51 and is greater than or equal to the outer diameter of the protrusion 511a.

[0030] A compression ring Y is provided on the outer side of the outer ring 512 of the upper filter assembly 51. The compression ring Y is a ring structure of latex sheet material with sufficient hardness and flexibility. The inner side is fixedly connected to the outer side of the outer ring 512. The outer diameter is equal to the inner diameter of the upper limit groove 12. When placed, due to the action of the compression ring Y, the upper filter assembly 51 is restricted at the upper limit groove 12, and the lower filter assembly 51 is restricted at the lower limit ring 13.

[0031] During filter pressing, the compression ring Y has a certain hardness and can withstand a certain pressure. By selecting appropriate thickness and hardness, it can withstand the pressure generated by the upper filter pressing. When the filter press cover plate 2 presses down to the compression ring Y, the downward pressure is increased, which can compress and deform the compression ring Y, causing it to come out of the upper limit groove 12. Then, it drives the filter screen assembly 51 above the filter press cover plate 2 to compress downward and continue the filter pressing.

[0032] As attached Figure 6 , 7 As shown in Figure 8, in another embodiment of this application, to ensure the stability of the trajectory of the filter assembly 51 during its up-and-down movement, the limiting rod 21b passes through the filter assembly 51 and the bottom of the filter press cover 2 and is fixed to the lower limiting ring 13. The corresponding filter cloth 510 needs to be provided with a structure through which the limiting rod 21b passes; that is, the filter cloth 510 is not a single circular filter cloth, but has a cut portion c, with adjacent cut portions overlapping, and a through hole at the top. Correspondingly, the filter assembly 51 and the filter press cover 2 are provided with through holes through which the limiting rod 21b passes, and an annular silicone scraper G is provided at the through hole. The inner diameter of the silicone scraper G is smaller than the outer diameter of the limiting rod 21b, used to scrape off the material from the limiting rod 21b.

[0033] It should be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between 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.
