Description

Technical Field

[0001] The present application relates to the technical field of bio-enzyme purification, and in particular to a device for efficiently concentrating and purifying bio-enzymes. Background Art

[0002] Bioenzymes, usually referred to as enzymes, are a class of proteins with biological catalytic effects. At present, in the biopharmaceutical, food processing and other industries, bioenzymes are important catalytic tools, and their efficient purification is a key link in improving product quality and reducing production costs. However, existing bioenzyme purification technologies are often plagued by problems such as low purity and low recovery rate, which limits the large-scale industrial application of bioenzymes. The bioenzyme concentration and purification device is a device used to improve the purity and activity of bioenzymes, which involves multiple steps such as filtration, separation, concentration and refining.

[0003] Currently, the commonly used bio-enzyme purification technology is to filter the bio-enzyme solution. Some filtration devices use multi-layer filtration technology, in which the inside of the filter tank is distributed with a coarse particle filtration layer, a grease adsorption layer, a fine particle filtration layer and a filter layer from top to bottom. This design can filter out conventional impurities from the bio-enzyme preparation to the greatest extent.

[0004] In the process of conventional biological enzyme solution filtration, the solution is generally introduced directly into the filter tank, and the solution falls directly on the filter net in the filter tank. The solution impacts the filter net, and then the solution passes through the filter net, leaving impurities in the solution on the filter net, and then the filtered solution flows directly out of the filter tank. However, when the solution is introduced into the filter tank, the filter net is generally fixed directly in the filter tank, and the solution will directly fall on a part of the filter net, making it difficult for other areas of the filter net to contact the solution, resulting in low utilization of the filter net, and the part of the filter net that often contacts the solution may also be blocked by impurities. Summary of the invention

[0034] The following is combined with Figure 1 —5 Further details of this application are provided.

[0035] The embodiment of the present application discloses a highly efficient bio-enzyme concentration and purification device.

[0036] Reference Figure 1 , Figure 2 and Figure 3 A biological enzyme efficient concentration and purification device comprises a purification tank 1, a supporting leg 2 is fixed to the bottom of the purification tank 1, a feeding pipe 3 is fixed to the top of the purification tank 1, a discharge pipe 4 is fixed to the bottom of the purification tank 1, an observation window 7 is fixed to the side of the purification tank 1, a mobile filtering mechanism 5 is arranged in the purification tank 1, and an auxiliary filtering mechanism 6 is arranged inside the purification tank 1.

[0037] When the concentration and purification device is used to purify the biological enzyme, the pretreatment solution is first fed into the purification tank 1 through the feed pipe to fill the purification tank 1, and then the mobile filtering mechanism 5 is used to move upward from the bottom of the purification tank 1. During the upward movement of the mobile filtering mechanism 5, the solution passes through the mobile filtering mechanism 5 evenly, and the mobile filtering mechanism 5 filters the impurities in the solution. At the same time, the mobile filtering mechanism 5 drives the liquid to stir during the upward movement to reduce the possibility that the impurities filtered out by the mobile filtering mechanism 5 affect the filtration. After the solution is filtered, the purified biological enzyme solution is discharged from the discharge pipe 4 to the external collection tank for storage and standby. When the solution flows out of the discharge pipe 4 of the purification tank 1, the solution passes through the auxiliary filtering mechanism 5.

During the movement of the mobile filtering mechanism 5, the mobile filtering mechanism 5 stirs the solution, so that the solution can pass through the mobile filtering mechanism 5 evenly, thereby improving the efficiency of solution filtration, and at the same time, it can reduce the possibility of clogging caused by the filtered impurities, affecting the normal filtration of the solution.

[0039] The filter screen 52 fixed on the support ring 51 is a microfiltration membrane. When the pretreatment solution is poured into the purification tank 1, a plurality of filter screens 52 are supported by the support ring 51 and are located at the bottom of the purification tank 1. After the solution fills the purification tank 1, the moving component 53 is used to drive a plurality of support rings 51, so that the support ring 51 drives the filter screen 52, and the filter screen 52 moves in the solution. The filter screen 52 filters the impurities in the solution. In the process of the support ring 51 driving the filter screen 52 to move, the support ring 51 drives the auxiliary stirring component, and the auxiliary stirring component performs turbulent flow stirring on the solution above the filter screen 52, so that the impurities filtered out by the filter screen 52 are removed from the filter screen 52. The surface is moved away. After the purification tank 1 is filled, the moving component 53 is used to drive several support rings 51, and the support ring 51 drives the filter screen 52 to allow the filter screen 52 to fully contact with the solution and move in the solution. At the same time, the support ring 51 drives the auxiliary stirring component to stir the solution above the filter screen 52, so that the solution to be filtered can fully contact with the filter screen 52, reducing the traditional purification that fixes the filter screen 52 and allows the solution to pass through the filter screen 52, resulting in the solution only impacting a part of the filter screen 52, causing the filter screen 52 to be blocked by impurities and the possibility of low filtration efficiency. At the same time, the possibility of impurities blocking the filter screen 52 can be reduced.

A support frame 532 is fixed on the purification tank 1, and a moving drive motor 534 is fixed on the support frame 532. The output end of the moving drive motor 534 passes through the purification tank 1 and is fixed with a moving threaded rod 533. The moving threaded rod 533 passes through the moving ring 531 and is threadedly connected to the moving ring 531.

[0041] After the purification tank 1 is filled with the solution, the mobile driving motor 534 drives the mobile threaded rod 533 to rotate, and the mobile threaded rod 533 drives the mobile ring 531, and the mobile ring 531 moves in the purification tank 1. The mobile ring 531 drives a plurality of support rings 51, and the support ring 51 drives the filter net 52 to move. After the purification tank 1 is filled, the mobile threaded rod 533 drives the mobile ring 531, and the mobile ring 531 drives the filter net 52 to move, so that the solution in the purification tank 1 can fully contact with the filter net 52, which is convenient for the filter net 52 to move in the solution and filter the impurities in the solution.

[0042] Reference Figure 2 , Figure 3 and Figure 4The auxiliary stirring mechanism 54 includes two support rods 541 symmetrically fixed on the support ring 51 , two symmetrical spoilers 542 are arranged between the two support rods 541 , and a rotating member 543 is arranged between the two support rods 541 and the two spoilers 542 .

[0043] In the process of moving ring 531 driving support ring 51 to move, support ring 51 drives support rod 541, support rod 541 drives rotating member 543 and spoiler 542, and in the process of moving rotating member 543, rotating member 543 drives spoiler 542 to rotate above filter screen 52, so that spoiler 542 stirs the solution, and the stirred solution drives impurities on filter screen 52 to move, and by making support ring 51 rotate on filter screen 52 when moving, spoiler 542 can move impurities on filter screen 52, thereby reducing the possibility of impurities clogging filter screen 52.

Under the action of the rotating threaded rod 5433, the rotating sleeve 5432 rotates on the rotating ring 5431, and the rotating sleeve 5432 drives the spoiler 542 to rotate. By allowing the support rod 541 to drive the rotating ring 5431 and the rotating ring 5431 to drive the rotating sleeve 5432, the rotating sleeve 5432 is rotated while moving along the rotating threaded rod 5433, so that the rotating sleeve 5432 can easily drive the spoiler 542 to rotate.

[0046] Reference Figure 2 and Figure 4The spoiler 542 is provided with a plurality of evenly distributed spoiler holes, and the spoiler holes face the direction of rotation of the spoiler 542. When the rotating sleeve 5432 drives the spoiler 542 to rotate, the spoiler holes on the spoiler 542 further disturb the solution, allowing the impurities on the filter screen 1 52 to move along with the flow of the solution. By providing a plurality of spoiler holes on the spoiler 542, the solution can be further disturbed when the spoiler 542 rotates, further reducing the possibility of impurities adhering to the filter screen 1 52.

During the discharge process, the filter screen 2 61 is used to filter the solution again. The filter screen 2 61 is a microfiltration membrane. At the same time, the movable threaded rod 533 drives the movable ring 531, and the movable ring 531 drives the filter screen 1 52 to reset. During the reset process, the movable threaded rod 533 drives the reciprocating assembly 63, and the reciprocating assembly 63 drives the reciprocating ring 62 to move back and forth. The reciprocating ring 62 drives the filter screen 2 61 to move back and forth, so that the impurities on the filter screen 2 61 are shaken up. By allowing the filter screen 2 61 to filter the solution again, and at the same time when the filter screen 1 52 is reset, the movable threaded rod 533 drives the reciprocating assembly 63, and the reciprocating assembly 63 drives the filter screen 2 61 to move back and forth, so that the impurities in the solution can be further reduced, and the possibility of impurities clogging the filter screen 2 61 can be reduced.

One end of the reciprocating threaded rod 632 passes through the reciprocating ring 631 and is fixedly connected to the movable threaded rod 533.

[0050] When the movable threaded rod 533 rotates, the movable threaded rod 533 drives the reciprocating threaded rod 632, and the reciprocating threaded rod 632 drives the reciprocating ring 62, so that the reciprocating ring 62 moves back and forth under the restriction of the reciprocating ring 631.
