Description

Technical Field

[0001] This invention belongs to the field of fermentation broth filtration technology, specifically a high-efficiency filtration device for compound probiotic fermentation broth. Background Technology

[0002] Compound probiotic fermentation broth refers to the liquid product obtained by inoculating two or more probiotic strains (such as lactic acid bacteria, bifidobacteria, yeast, etc.) into a nutrient-rich liquid culture medium (such as soy milk, milk, fruit and vegetable juice, molasses, etc.) and fermenting it at a suitable temperature for a period of time.

[0003] Currently, filtration of compound probiotic fermentation broth is a core step in the production process. Its core objective is to accurately separate bacteria, metabolites, and fermentation substrates to meet the physicochemical properties requirements of different end products. At present, the industry generally uses filter cloth filtration technology. However, during continuous operation, the pores of the filter cloth are easily blocked by residual fermentation substrates (such as undegraded polysaccharides, protein complexes, and bacterial fragments), resulting in a decrease in filtration flux and an increase in transmembrane pressure difference, which significantly affects separation efficiency and product yield. More importantly, traditional filter cloth cleaning and maintenance requires disassembling the entire filtration unit, which not only interrupts production continuity but also consumes time and labor for manual cleaning, reducing equipment utilization. Therefore, a high-efficiency filtration device for compound probiotic fermentation broth is proposed. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a high-efficiency filtration device for compound probiotic fermentation broth. This device solves the problems in the production of compound probiotic fermentation broth where filter cloth filtration is the mainstream technology, but it suffers from problems such as easy clogging (e.g., polysaccharides, protein complexes), decreased throughput, and increased pressure differential, which affect separation efficiency and yield. Furthermore, cleaning requires disassembling the filter unit, leading to production interruptions, high labor costs, and reduced equipment utilization.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency filtration device for compound probiotic fermentation broth, comprising a filter cover, and further comprising: A filter assembly, which is installed inside the filter cover; A top cover assembly, which is fixedly mounted on the top of the filter cover, is used to inject compound probiotic fermentation liquid into the filter assembly; A sealing assembly, disposed inside the filter cover, is used to seal the bottom of the filter assembly; The filter assembly includes a first support docking ring movably installed inside the filter cover, and a cylindrical filter cloth is provided at the bottom of the first support docking ring. A second support docking ring is fixedly installed at the bottom of the tubular filter cloth, and a third support docking ring is fixedly installed outside the second support docking ring. The third support docking ring slides vertically inside the filter cover.

[0006] Preferably, a first transmission gear is fixedly mounted on the outside of the first support docking ring, and a second transmission gear that meshes with the first transmission gear is provided inside the filter cover; The filter cover is equipped with a motor that drives the second transmission gear.

[0007] Preferably, the inner wall of the filter cover is provided with a vertical guide groove, and the third support docking ring slides vertically in the vertical guide groove through a sliding member; When the cylindrical filter cloth is rotated by a motor so that its middle part is spiral, the bottom of the cylindrical filter cloth pulls the second support docking ring and the third support docking ring to move upward along the vertical guide groove.

[0008] Preferably, the top cover assembly injects a compound probiotic fermentation liquid into the cylindrical filter cloth and filters it through the cylindrical filter cloth. The motor drives the second transmission gear, the first transmission gear, the first support docking ring, and the upper end of the cylindrical filter cloth to rotate in opposite directions, thereby causing the compound probiotic fermentation liquid inside the cylindrical filter cloth to shake synchronously.

[0009] Preferably, the third support docking ring has a ring array of connecting holes. The top cover assembly injects the compound probiotic fermentation liquid into the cylindrical filter cloth. After being filtered by the cylindrical filter cloth, the filtrate enters the lower end of the filter cover through the connecting holes and is discharged through the drain pipe.

[0010] Preferably, the top cover assembly includes a top cover body fixedly mounted on the top of the filter cover, and a fermentation liquid injection pipe for injecting compound probiotic fermentation liquid into the cylindrical filter cloth is fixedly mounted in the middle of the top cover body; The inner wall of the first support docking ring is fixedly fitted with a stable receiving ring, which is movably sleeved on the outside of the fermentation broth injection pipe.

[0011] Preferably, when the first transmission gear, the first support docking ring, and the upper end of the cylindrical filter cloth rotate, they simultaneously drive the stable receiving ring to rotate around the fermentation liquid injection pipe as the central axis, and the fermentation liquid injection pipe continuously injects compound probiotic fermentation liquid into the cylindrical filter cloth.

[0012] Preferably, the sealing assembly includes a gathering cover fixedly mounted on the bottom of the second support docking ring, a cross fixing frame fixedly mounted inside the gathering cover, a support guide rod movably sleeved in the middle of the cross fixing frame, and a conical sealing column fixedly mounted on the top of the support guide rod.

[0013] Preferably, the second support docking ring has a through hole in the middle that matches the outer diameter of the sealing column, an electromagnet is provided at the bottom of the second support docking ring, and a metal transmission ring is fixedly installed on the outside of the sealing column. Initially, the electromagnet is energized to attract the metal transmission ring, causing the sealing post to be fitted into the through hole in the middle of the second support docking ring.

[0014] Preferably, the bottom of the gathering cover is connected to an elastic corrugated pipe, the bottom of the elastic corrugated pipe is connected to a slag discharge pipe, and the slag discharge pipe is fixedly installed at the bottom of the filter cover.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention injects a compound probiotic fermentation broth into the interior of a cylindrical filter cloth via a top cover assembly. A sealing assembly then seals the bottom of the filter cloth, allowing the fermentation broth to be filtered. The treated broth is discharged through a drain pipe, while impurities remain inside the filter cloth. When long-term filtration requires cleaning of the inner wall of the filter cloth, the sealing assembly disengages. A motor drives a second transmission gear, a first transmission gear, and a first support ring to rotate the filter cloth in both directions. The bottom of the filter cloth slides vertically against the inner wall of the filter cover via a third and second support ring, creating a spiral shape in the middle of the filter cloth. Repeated rotations cause impurities adhering to the inner wall of the filter cloth to be squeezed off and discharged through the sealing assembly and the bottom of the filter cover. This process eliminates the need to disassemble the entire filter unit, improving the efficiency of cleaning the filter cloth and ensuring high equipment utilization.

[0016] This invention closes the top cover and injects clean water into the filter hood through the drain pipe. The water then enters through the outside of the cylindrical filter cloth and exits along the sealing assembly, thereby backwashing the cylindrical filter cloth with the clean water and further improving the cleaning effect of the cylindrical filter cloth.

[0017] This invention injects the compound probiotic fermentation liquid into a cylindrical filter cloth through a top cover assembly. A motor drives the second transmission gear, the first transmission gear, the first support docking ring, and the upper end of the cylindrical filter cloth to rotate. During the rotation of the cylindrical filter cloth, the compound probiotic fermentation liquid inside moves synchronously. The movement increases the contact area between the compound probiotic fermentation liquid and the cylindrical filter cloth, thereby improving the filtration efficiency of the compound probiotic fermentation liquid.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 8 As shown, the present invention provides a high-efficiency filtration device for compound probiotic fermentation broth, including a filter cover 1, and further comprising: Filter assembly 6 is installed inside filter cover 1; Top cover assembly 2, which is fixed to the top of filter cover 1, is used to inject compound probiotic fermentation liquid into filter assembly 6; The sealing component 5 is disposed inside the filter cover 1 and is used to seal the bottom of the filter component 6; The filter assembly 6 includes a first support docking ring 61 that is movably installed inside the filter cover 1, and a cylindrical filter cloth 62 is provided at the bottom of the first support docking ring 61. A second support docking ring 65 is fixedly installed at the bottom of the cylindrical filter cloth 62, and a third support docking ring 68 is fixedly installed on the outside of the second support docking ring 65. The third support docking ring 68 slides vertically inside the filter cover 1. The first support docking ring 61 is fixedly equipped with a first transmission gear 63 on its outside, and the filter cover 1 is provided with a second transmission gear 64 that meshes with the first transmission gear 63 inside. The filter cover 1 is equipped with a motor that drives the second transmission gear 64.

[0022] The compound probiotic fermentation broth is injected into the cylindrical filter cloth 62 through the top cover assembly 2. The bottom of the cylindrical filter cloth 62 is sealed by the sealing assembly 5. The compound probiotic fermentation broth is filtered through the cylindrical filter cloth 62, and the treated fermentation broth is discharged through the drain pipe 3. Impurities in the fermentation broth remain inside the cylindrical filter cloth 62. When the cylindrical filter cloth 62 needs to be cleaned of impurities on its inner wall for long-term filtration, the sealing assembly 5 disengages from the cylindrical filter cloth 62. The second transmission gear 64 and the first transmission gear 63 are driven by the motor. The first support docking ring 61 rotates in both directions with the cylindrical filter cloth 62, while the bottom of the cylindrical filter cloth 62 slides vertically against the inner wall of the filter cover 1 through the third support docking ring 68 and the second support docking ring 65, so that the middle part of the cylindrical filter cloth 62 is in a positive spiral shape and a negative spiral shape. Through multiple forward and reverse rotations, the impurities attached to the inner wall of the cylindrical filter cloth 62 are squeezed off and discharged through the sealing component 5 and the bottom of the filter cover 1. In this process, there is no need to disassemble the entire filter unit, which improves the cleaning efficiency of the cylindrical filter cloth 62 and ensures the utilization rate of the equipment. At the same time, the top cover assembly 2 is closed, and cleaning water is injected into the filter cover 1 through the drain pipe 3. The water enters through the outside of the cylindrical filter cloth 62 and is discharged along the sealing assembly 5. The cleaning water backwashes the cylindrical filter cloth 62, further improving the cleaning effect of the cylindrical filter cloth 62.

[0023] like Figures 3-6 As shown, the inner wall of the filter cover 1 is provided with a vertical guide groove 69, and the third support docking ring 68 slides vertically in the vertical guide groove 69 through the sliding member 67; When the cylindrical filter cloth 62 is rotated by the motor so that its middle part is spiral, the bottom of the cylindrical filter cloth 62 pulls the second support docking ring 65 and the third support docking ring 68 to move upward along the vertical guide groove 69.

[0024] The compound probiotic fermentation liquid is injected into the cylindrical filter cloth 62 through the top cover assembly 2. Since the lower end of the cylindrical filter cloth 62 slides vertically in the vertical guide groove 69 through the third support docking ring 68, the second support docking ring 65 and the sliding member 67, the upper end of the cylindrical filter cloth 62 is rotated by the second transmission gear 64, the first transmission gear 63, the first support docking ring 61 and the cylindrical filter cloth 62 through the motor, so that the middle part of the cylindrical filter cloth 62 is spiral. During this process, the lower end of the cylindrical filter cloth 62 pulls the second support docking ring 65 and the third support docking ring 68 to move upward along the vertical guide groove 69 through the sliding member 67, thereby ensuring that the middle part of the cylindrical filter cloth 62 can be spiral, improving the effect of cleaning impurities on the inner wall of the cylindrical filter cloth 62.

[0025] like Figures 1-5 As shown, the top cover assembly 2 injects the compound probiotic fermentation liquid into the cylindrical filter cloth 62 and filters it through the cylindrical filter cloth 62. The motor drives the second transmission gear 64, the first transmission gear 63, and the first support docking ring 61 to rotate in opposite directions with the upper end of the cylindrical filter cloth 62, thereby causing the compound probiotic fermentation liquid in the cylindrical filter cloth 62 to shake synchronously.

[0026] The compound probiotic fermentation liquid is injected into the cylindrical filter cloth 62 through the top cover assembly 2. The motor drives the second transmission gear 64, the first transmission gear 63, and the first support docking ring 61 to rotate in both directions with the upper end of the cylindrical filter cloth 62. During the rotation of the cylindrical filter cloth 62, the compound probiotic fermentation liquid inside is driven to shake synchronously. During the shaking process, the contact area between the compound probiotic fermentation liquid and the cylindrical filter cloth 62 is increased, thereby improving the filtration efficiency of the compound probiotic fermentation liquid.

[0027] like Figure 6 and Figure 8 As shown, the third support docking ring 68 has a ring array of connecting holes. The top cover assembly 2 injects the compound probiotic fermentation liquid into the cylindrical filter cloth 62. After being filtered by the cylindrical filter cloth 62, the filtrate enters the lower end of the filter cover 1 through the connecting holes and is discharged through the drain pipe 3.

[0028] Initially, the bottom of the cylindrical filter cloth 62 is blocked by the sealing component 5, and the compound probiotic fermentation liquid is injected into the cylindrical filter cloth 62. After being filtered by the cylindrical filter cloth 62, it enters the lower end of the filter cover 1 through the connecting hole and is then discharged and collected through the drain pipe 3, thus realizing the filtration treatment of the compound probiotic fermentation liquid.

[0029] like Figure 2 and Figure 3 As shown, the top cover assembly 2 includes a top cover body 21 fixed to the top of the filter cover 1, and a fermentation liquid injection pipe 22 for injecting compound probiotic fermentation liquid into the tubular filter cloth 62 is fixed in the middle of the top cover body 21. The inner wall of the first support docking ring 61 is fixedly fitted with a stable receiving ring 23, which is movably sleeved on the outside of the fermentation broth injection pipe 22. When the first transmission gear 63, the first support docking ring 61 and the upper end of the cylindrical filter cloth 62 rotate, they simultaneously drive the stable receiving ring 23 to rotate around the fermentation liquid injection pipe 22 as the central axis. The fermentation liquid injection pipe 22 continuously injects compound probiotic fermentation liquid into the cylindrical filter cloth 62.

[0030] The fermentation broth injection pipe 22 is connected to the injection equipment, and the compound probiotic fermentation broth is injected into the interior of the cylindrical filter cloth 62 through the fermentation broth injection pipe 22. The cylindrical filter cloth 62 then filters the broth. During the process, the second transmission gear 64, the first transmission gear 63, the first support docking ring 61 and the cylindrical filter cloth 62 are driven by the motor to rotate in both directions. During the rotation, the stable receiving ring 23 rotates in both directions around the fermentation broth injection pipe 22 as the central axis, thereby ensuring that the fermentation broth injection pipe 22 can continuously inject the compound probiotic fermentation broth into the cylindrical filter cloth 62 for continuous filtration.

[0031] like Figures 6-8 As shown, the sealing assembly 5 includes a gathering cover 66 fixedly mounted on the bottom of the second support docking ring 65. A cross fixing frame 55 is fixedly mounted inside the gathering cover 66. A support guide rod 54 is movably sleeved in the middle of the cross fixing frame 55. A conical sealing column 51 is fixedly mounted on the top of the support guide rod 54. The second support docking ring 65 has a through hole in the middle that matches the outer diameter of the sealing column 51. An electromagnet 52 is provided at the bottom of the second support docking ring 65, and a metal transmission ring 53 is fixedly installed on the outside of the sealing column 51. When the initial electromagnet 52 is energized, it attracts the metal transmission ring 53, causing the sealing column 51 to be fitted into the through hole in the middle of the second support docking ring 65. The bottom of the gathering cover 66 is connected to an elastic bellows 56, and the bottom of the elastic bellows 56 is connected to a slag discharge pipe 57, which is fixed to the bottom of the filter cover 1.

[0032] When the electromagnet 52 is energized, the metal transmission ring 53 is attracted by the magnetic force, causing the support guide rod 54 to move upward along the cross-shaped fixing frame 55. The sealing column 51 is fitted into the through hole in the middle of the second support docking ring 65, thus sealing the second support docking ring 65 and the cylindrical filter cloth 62. The compound probiotic fermentation broth is injected into the cylindrical filter cloth 62 through the fermentation broth injection pipe 22 to achieve filtration. During the rotation of the cylindrical filter cloth 62 driven by the motor, the lower end of the cylindrical filter cloth 62 pulls the third support docking ring 68 along the inner wall of the filter cover 1. The movement simultaneously causes the gathering cover 66 to stretch the elastic corrugated tube 56, thereby ensuring that the cylindrical filter cloth 62 can rotate normally. When it is necessary to clean the filter impurities on the inner wall of the cylindrical filter cloth 62, the electromagnet 52 is de-energized, and the sealing column 51 moves down along the cross fixing frame 55 through the support guide rod 54 under its own weight, so that the through hole in the middle of the second support docking ring 65 is in a conductive state. Then, the motor drives the cylindrical filter cloth 62 to rotate forward and backward to clean the filter impurities on the inner wall, and discharges them through the gathering cover 66, the elastic corrugated tube 56 and the slag discharge pipe 57.

[0033] Working principle and usage process of this invention: When the electromagnet 52 is energized, the metal transmission ring 53 is attracted by the magnetic force, causing the support guide rod 54 to move upward along the cross fixing frame 55. The sealing column 51 is sleeved in the through hole in the middle of the second support docking ring 65, thereby sealing the second support docking ring 65 and the cylindrical filter cloth 62. The fermentation liquid injection pipe 22 is connected to the injection equipment, and the compound probiotic fermentation liquid is injected into the interior of the cylindrical filter cloth 62 through the fermentation liquid injection pipe 22. The compound probiotic fermentation liquid is filtered through a cylindrical filter cloth 62. The treated fermentation liquid is discharged through the drain pipe 3, while the impurities in the fermentation liquid remain inside the cylindrical filter cloth 62. The motor drives the second transmission gear 64, the first transmission gear 63, and the first support docking ring 61 to rotate in both directions with the upper end of the cylindrical filter cloth 62. During the rotation of the cylindrical filter cloth 62, the compound probiotic fermentation liquid inside is driven to shake synchronously. During the shaking process, the contact area between the compound probiotic fermentation liquid and the cylindrical filter cloth 62 is increased, thereby improving the filtration efficiency of the compound probiotic fermentation liquid. The compound probiotic fermentation broth is filtered through a cylindrical filter cloth 62. The treated broth is discharged through the drain pipe 3, while impurities remain inside the cylindrical filter cloth 62. When the cylindrical filter cloth 62 needs to be cleaned of impurities after long-term filtration, the electromagnet 52 is de-energized. Under its own weight, the sealing column 51 moves down along the cross-shaped fixing frame 55 via the support guide rod 54, making the through hole in the middle of the second support docking ring 65 open. The motor drives the second transmission gear 64, the first transmission gear 63, the first support docking ring 61, and the cylindrical filter cloth 62 to rotate in both directions. During this process, the cylindrical filter cloth... The lower end of the filter cloth 62 pulls the second support docking ring 65 and the third support docking ring 68 upward along the vertical guide groove 69 via the sliding member 67, so that the middle part of the cylindrical filter cloth 62 is in a positive spiral shape and a negative spiral shape. Through multiple forward and reverse rotations, the impurities attached to the inner wall of the cylindrical filter cloth 62 are squeezed off. The lower end of the cylindrical filter cloth 62 pulls the third support docking ring 68 upward along the inner wall of the filter cover 1, while driving the gathering cover 66 to stretch the elastic corrugated tube 56, thereby ensuring that the cylindrical filter cloth 62 can rotate normally. The cleaned filter impurities are discharged through the gathering cover 66, the elastic corrugated tube 56 and the slag discharge pipe 57.
