Description

Technical Field

[0001] This utility model relates to the field of seaweed extract filtration technology, and in particular to a filtration device for seaweed extract. Background Technology

[0002] In the processing of seaweed extracts, filtration is a crucial step in ensuring the purity of the extract and the stability of subsequent processes. However, seaweed extracts have a complex and unique composition. Their mixtures not only contain a large amount of large particles of residue from broken algae and fibrous impurities, but also fine components such as polysaccharide colloids, pigment molecules, and tiny algal spores.

[0003] Existing filtration devices mostly use a single filtration structure. If they only use a filter screen for simple filtration, it is difficult to simultaneously achieve effective retention of large particulate impurities and deep purification of fine components. This results in insufficient clarity of the filtered extract, and residual viscous impurities and small molecule contaminants can easily affect the subsequent separation and purification of active ingredients. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a filtration device for seaweed extracts.

[0006] Preferably, a filter cartridge is provided inside the filter cartridge, directly below the filter disc. The filter cartridge has a box-shaped structure with openings at the top and bottom, and its interior is filled with microporous medium in the vertical direction. The outer peripheral wall of the filter cartridge is fitted with the inner wall of the filter cartridge with a clearance.

[0007] Preferably, the inner wall of the filter cartridge is provided with horizontally protruding positioning blocks on both sides corresponding to the filter cartridge. The positioning blocks extend along the axial direction of the filter cartridge, and the two side walls of the filter cartridge slide against the positioning blocks. The top end of the filter cartridge is recessed inward to form a receiving groove. A lifting ring is rotatably connected in the receiving groove. The lifting ring can be rotated upward around the connecting axis to the outside of the receiving groove, so as to drive the filter cartridge to be pulled out of the filter cartridge along the axial direction of the positioning blocks.

[0008] Preferably, a liquid pump is fixedly installed on the outer wall of the filter cartridge. The input end of the liquid pump is connected to the inner cavity of the filter cartridge below the filter cartridge through a pipe, and the output end extends upward through a pipe and is connected to the inner cavity of the filter cartridge above the filter cartridge, forming a liquid circulation path from the bottom to the top of the filter cartridge.

[0009] Preferably, the two side walls of the filter cylinder are provided with horizontally penetrating U-shaped grooves at the height position corresponding to the filter disc. The opening of the U-shaped groove faces the outside of the filter cylinder. Both ends of the filter disc are respectively embedded in the U-shaped groove and slide in cooperation with the groove wall. One end of the filter disc extends out of the U-shaped groove and is fixedly connected to a handle. The handle can drive the filter disc to slide into or out of the filter cylinder along the axial direction of the U-shaped groove.

[0010] Preferably, a collection frame is provided inside the filter cylinder below the filter disc, and positioning hooks extend upward from both sides of the top of the collection frame. A positioning groove is correspondingly provided on the bottom surface of the filter disc, and the positioning hooks can be inserted upward into the positioning groove to form a detachable connection.

[0011] Preferably, the bottom surface and peripheral wall of the collection frame are provided with a plurality of through holes, the diameter of which is smaller than the filtration pore diameter of the filter plate, so as to allow liquid to pass through and trap impurities.

[0012] Preferably, the bottom of the filter cartridge is provided with a liquid outlet, wherein the liquid outlet is equipped with a valve to control the discharge.

[0013] Compared with existing technologies, the advantages and positive effects of this utility model are as follows: by using the filter disc to initially intercept large algal residues and fibrous impurities, and in conjunction with the microporous media (such as modified activated carbon) in the filter cartridge adapted to seaweed extract to adsorb and sieve fine components such as polysaccharide colloids and pigment molecules, a multi-stage filtration system is formed; at the same time, the circulation path driven by the liquid pump causes the extract to flow through the filter cartridge multiple times, which enhances the removal of viscous impurities and small molecule pollutants, effectively improving the clarity and purity of the seaweed extract and meeting the process requirements for subsequent separation and purification of active ingredients.

[0016] Example 1, such as Figure 1-5As shown, a filtration device for seaweed extract includes a vertically arranged filter cylinder 1. A horizontally extending inlet 2 is connected to the upper side wall of the filter cylinder 1. The end of the inlet 2 away from the filter cylinder 1 is inclined upwards and connected to a feed trough 3. The outlet end of the feed trough 3 is sealed to the inlet 2. A filter disc 4 is horizontally arranged inside the filter cylinder 1. The edge of the filter disc 4 is sealed to the inner wall of the filter cylinder 1, and the filter disc 4 is located directly below the inlet 2, forming a path for the seaweed extract flowing in from the feed trough 3 through the inlet 2 to first pass through the filter disc 4 for filtration. The filter disc 4 can be made of stainless steel mesh and has rubber sealing gaskets on its edges to enhance the sealing effect. A filter cartridge 5 is located inside the filter cylinder 1 directly below the filter disc 4. The filter cartridge 5 has a box-shaped structure with openings at the top and bottom. Its interior is filled with a microporous medium along the vertical direction. The microporous medium can be activated carbon particles. The outer peripheral wall of the filter cartridge 5 is fitted with a clearance fit to the inner wall of the filter cylinder 1. Metal support mesh is provided at both the top and bottom openings of the filter cartridge 5 to prevent leakage of the microporous medium. Positioning blocks 6 are horizontally protruding from the inner wall of the filter cartridge 1 on both sides corresponding to the filter cartridge 5. The positioning blocks 6 extend axially along the filter cartridge 1, and the two side walls of the filter cartridge 5 slide against the positioning blocks 6. The length of the positioning blocks 6 is adapted to the height of the filter cartridge 5 to ensure support stability. The top end of the filter cartridge 5 is recessed inward to form a receiving groove 7. A lifting ring 8 is rotatably connected to the receiving groove 7 by a metal pin. The lifting ring 8 can rotate upward around the metal pin to the outside of the receiving groove 7, so as to drive the filter cartridge 5 to be pulled out of the filter cartridge 1 along the axial direction of the positioning blocks 6. A liquid pump 9 is fixedly installed on the outer wall of the filter cartridge 1 by bolts. The input end of the liquid pump 9 is connected to the inner cavity of the filter cartridge 1 below the filter cartridge 5 through a corrosion-resistant pipe, and the output end extends upward through a corrosion-resistant pipe and is connected to the inner cavity of the filter cartridge 1 above the filter cartridge 5. The connection between the corrosion-resistant pipe and the filter cartridge 1 is sealed by welding, forming a liquid circulation path from the bottom to the top of the filter cartridge 5. A horizontally penetrating U-shaped groove 10 is formed on both side walls of the filter cartridge 1 at the height position corresponding to the filter disc 4. The opening of the U-shaped groove 10 faces the outside of the filter cartridge 1. Both ends of the filter disc 4 are respectively embedded in the U-shaped groove 10 and slide in cooperation with the groove wall. A guide strip is provided on the inner side wall of the U-shaped groove 10, and a guide groove is correspondingly formed at the end of the filter disc 4 to enhance the smoothness of sliding. One end of the filter disc 4 extends out of the U-shaped groove 10 and is fixedly connected to a handle 11 by welding. The handle 11 is made of plastic and has anti-slip texture on the surface. The handle 11 can drive the filter disc 4 to slide into or out of the filter cartridge 1 along the axial direction of the U-shaped groove 10. Inside the filter cartridge 1, below the filter disc 4, there is a collection frame 12. The top two sides of the collection frame 12 extend upward with positioning hooks 13. The positioning hooks 13 are made of elastic metal sheet material. A positioning groove 14 is correspondingly formed on the bottom surface of the filter disc 4. The positioning hooks 13 can be inserted upward into the positioning groove 14 to form a detachable connection. When the filter disc 4 slides along the U-shaped groove 10, the collection frame 12 moves synchronously with the filter disc 4 to collect the impurities on the filter disc 4. The depth of the collection frame 12 is set to accommodate the amount of impurities accumulated on the filter disc 4.The bottom surface and peripheral wall of the collection frame 12 are provided with several through holes. The diameter of the through holes is smaller than the filter hole diameter of the filter plate 4 so as to allow liquid to pass through and trap impurities. The through holes are evenly distributed on the collection frame 12 to ensure smooth liquid flow.

[0017] Working principle: The seaweed extract mixture enters from the feed tank 3 and flows into the filter cartridge 1 through the inlet 2, first contacting the horizontally arranged filter disc 4. Since seaweed extract often contains large particles such as broken algae residue and fibrous impurities, the filter disc 4 traps these particles through its surface pores, causing them to remain on its surface. The initially filtered extract then flows downwards under gravity to the bottom of the filter disc 4, preventing large particles from clogging subsequent filtration structures. The filter cartridge 5 below the filter disc 4 is filled with microporous media (such as modified activated carbon or ceramic filter media) suitable for filtering seaweed extract. This type of media further purifies the liquid through adsorption and sieving of polysaccharide colloids, pigment molecules, and tiny algal spores contained in the seaweed extract. Simultaneously, the pump 9 pumps a portion of the extract from below the filter cartridge 5 to the top, forming a circulating filtration path. This allows the extract to flow through the microporous media multiple times, enhancing the removal of the unique viscous impurities and soluble small molecule pollutants of seaweed and improving filtration accuracy. When algae residue accumulates to a certain extent on filter plate 4, filter plate 4 is pulled out along U-shaped groove 10 using handle 11. Collection frame 12 moves synchronously with filter plate 4. The residue is scraped into collection frame 12 by the cooperation of positioning hook 13 and positioning groove 14. The through holes of collection frame 12 allow residual extract to flow back, collecting only solid residue and avoiding raw material waste. Filter cartridge 5 can be easily removed along positioning block 6 using lifting ring 8. The microporous media is replaced periodically to maintain a balance between the retention of active ingredients and the removal of impurities in the seaweed extract. Finally, through the synergistic effect of multi-stage filtration, a clear and pure seaweed extract is obtained and discharged through outlet 15, meeting the process requirements for subsequent separation and purification of active ingredients. Through the synergistic effect of various components, effective filtration of seaweed extract and convenient maintenance of the device are achieved. The bottom of filter cartridge 1 is equipped with outlet 15, which is equipped with a valve to control discharge.
