Description

Technical Field

[0001] The invention relates to the technical field of separation and purification, and more specifically to a separation and purification device for millet alcohol-soluble protein peptides. Background Art

[0002] Millet alcohol-soluble protein peptide is a protein fragment extracted from millet through special biotechnology. It has multiple biological activities and nutritional values. This peptide substance not only retains the original nutrients of millet, but also has the characteristics of small molecular weight and easy absorption by the human body. It is widely used in the fields of health food, health care products and cosmetics. After enzymatic hydrolysis of millet to obtain alcohol-soluble protein peptide, the extract needs to be purified and separated. This process requires the use of a dedicated separation and purification device;

[0003] In the existing technical means, the purification process of prolamin peptides usually includes injecting its raw materials into a specific purification box. In this process, impurities in the raw solution are removed by using precision filters to ensure that the final product reaches the required purity and quality standards. However, this method faces some significant problems in actual operation:

[0004] The filters used in the purification process need to be replaced frequently, which not only increases production costs, but may also lead to a decrease in production efficiency. Since the filters will gradually become clogged during use, they need to be shut down regularly for replacement and maintenance, which will undoubtedly affect the continuity and stability of the entire production line. In addition, frequent replacement of filters will also increase the amount of waste generated, causing certain pressure on the environment.

[0005] Therefore, the present invention proposes a separation and purification device for millet alcohol-soluble protein peptides, which can realize automatic dredging and waste discharge of the filter element when the flowability of the filter element decreases, thereby improving purification efficiency and reducing costs. Summary of the invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a separation and purification device for millet alcohol-soluble protein peptides to solve the problem existing in the above-mentioned background technology of how to realize automatic dredging and waste discharge of the filter element when the fluidity of the filter element decreases, thereby improving purification efficiency and reducing costs.

[0011] When the flow-blocking baffle moves downward together with the U-shaped connecting frame, the opening on the flow-blocking baffle gradually approaches the waste discharge pipe until the clearing head on the top wall of the clearing piece approaches the filter plate, and the opening of the flow-blocking baffle begins to enter the waste discharge pipe. At this time, the accumulated liquid continues to be pressurized by the overlapping pressure plates and is discharged from the open waste discharge pipe, while the clearing head of the clearing piece gradually penetrates into the filter holes to clear the dirt blocking the filter holes, thereby clearing and discharging impurities and waste.

[0012] Furthermore, the left and right screw rods pass through the clearing piece, and the top ends are connected to the filter plate, while the bottom ends of the screw rods are fixedly sleeved on the double-strand pulleys, and the double-strand pulleys are connected by synchronous belt transmission.

When the separation chamber is in an abnormal flow state, the output shaft of the reversible motor drives the single-strand rotating wheel and the double-strand pulley to rotate forward, so that the lifting platform threadedly sleeved with the lead screw can carry the dredging component to rise and gradually approach the bottom of the filter plate. At the same time, through the transmission of the bevel gears on the driving roller and the driven roller, the driven roller and the flat gear reversely spin and drive the rack to slide downward along the slide rail of the side wall of the purification box, so that the rack can carry the U-shaped connecting frame and the pressure plate to descend, and approach and fit the pressure plate of the lower layer, forcing the through holes on the surfaces of the two to be offset and distributed to each other. Shielding is used to block the path of the original liquid flowing to the filter plate. As the clearing piece continues to rise, the overlapping pressure plates continue to descend, and the accumulated liquid remaining between the pressure plate and the filter plate is pressurized, so that the residual alcohol-soluble protein peptides in the accumulated liquid can penetrate from the blocked filter holes as much as possible. At the same time, the flow-blocking baffle passing through the waste pipe moves down together with the U-shaped connecting frame. When the clearing head on the top wall of the clearing piece approaches the filter plate, the opening of the flow-blocking baffle begins to enter the waste pipe. At this time, the accumulated liquid continues to be pressurized by the overlapping pressure plates and is discharged from the open waste pipe, while the clearing head of the clearing piece gradually pokes into the filter holes to dredge the dirt blocking the filter holes, thereby achieving the dredging and discharge of impurities and waste.

[0040] Through the mesh opening on the dredging member 3, the alcohol-soluble protein peptide separated by the filter plate 2 can smoothly pass through the mesh opening and fall into the discharge hopper without being blocked by the dredging member 3;

[0041] The sealing cover 504 is communicated with the discharge chamber to accommodate the single-strand rotor 503 and ensure the sealing of the purification box 1 to prevent the leakage of alcohol-soluble protein peptides.

[0042] Working principle of the present invention:

[0043] The alcohol-soluble protein peptide extract (stock solution) obtained by enzymatic hydrolysis of millet is injected into the purification box 1 from the feed hopper, and the stock solution flows to the filter plate 2 after passing through the through holes staggered between the upper and lower pressing plates 401, so that the stock solution introduced into the separation chamber can be separated and purified by the filter plate 2, so that the alcohol-soluble protein peptides therein can smoothly pass through the filter holes and fall into the discharge hopper of the purification box 1, and then converge to the collection device from the discharge hopper, while other impurities are blocked above the filter plate 2, thereby achieving separation and purification of the stock solution;

[0044] When the separation chamber is in an abnormal flow state, that is, the filter plate 2 is blocked, the output shaft of the reversible motor 506 drives the single-strand rotating wheel 503 connected thereto to rotate forward through the coupling, and the single-strand rotating wheel 503 drives the left double-strand belt pulley 502 through the steel belt, and the left and right double-strand belt pulleys 502 are driven by the synchronous belt, so that the screw rod 501 connected to the left and right double-strand belt pulleys 502 rotates forward synchronously, so that the lifting platform 505 threadedly sleeved with the screw rod 501 can carry the dredging member 3 and lift it vertically, and gradually move it to the bottom of the filter plate 2. At the same time, the right-side double-strand pulley 502 drives the single-strand rotating wheel 503 on the same side through the steel belt, so that the right-side single-strand rotating wheel 503 can carry the transmission roller 601 to rotate coaxially, and then the rotating transmission roller 601 transmits the torque to the driven roller 602 by means of the vertically meshing bevel gear 603, so that the driven roller 602 and the flat gear 604 rotate in the opposite direction, and then the counter-rotating flat gear 604 drives the meshing rack 605, so that it slides downward along the slide rail of the side wall of the purification box 1, so that the rack 605 can carry the U-shaped The connecting frame 402 and the pressing plate 401 connected to its bottom end are lowered as a whole, gradually approaching and fitting the pressing plate 401 of the lower layer, forcing the through holes on the surfaces of the two layers to cover each other, so as to block the path of the raw liquid flowing to the filter plate 2. As the dredging member 3 continues to rise, the superimposed pressing plate 401 continues to fall, and the tube bore 403 falls with the pressing plate 401 of the lower layer and compresses the spring 405, pressurizing the accumulated liquid between the pressing plate 401 and the filter plate 2, so that the alcohol-soluble protein peptides remaining in the accumulated liquid can penetrate out from the blocked filter holes as much as possible. At the same time, the flow-blocking baffle 702 passing through the waste pipe 701 moves downward together with the U-shaped connecting frame 402, and the opening on the flow-blocking baffle 702 gradually approaches the waste pipe 701. When the dredging head on the top wall of the dredging member 3 approaches the filter plate 2, the opening of the flow-blocking baffle 702 begins to enter the waste pipe 701. At this time, the accumulated liquid continues to be pressurized by the superimposed pressure plate 401 and is discharged from the open waste pipe 701, while the dredging head of the dredging member 3 gradually pokes into the filter hole to dredge the dirt blocking the filter hole, thereby achieving the dredging and waste discharge of impurities and waste;

[0045] When the flow crisis in the separation chamber is resolved, that is, the filter plate 2 is not blocked, the output shaft of the reversible motor 506 drives the single-strand rotating wheel 503 connected thereto to rotate in the opposite direction through the coupling, thereby changing the transmission direction of the double-strand pulley 502 and the screw rod 501, so that the lifting platform 505 threadedly connected to the screw rod 501 can carry the dredging member 3 and vertically descend to gradually move away from the filter plate 2, and at the same time change the transmission direction of the driving roller 601 and the driven roller 602, resulting in the driven roller 602 and the flat gear 606. 04 positive coaxial rotation, and then the positive spinning flat gear 604 transmits the meshing rack 605 to make it slide upward along the slide rail of the side wall of the purification box 1, so that the rack 605 can carry the U-shaped connecting frame 402, the upper pressure plate 401 and the flow-blocking baffle 702 to rise, and the lower pressure plate 401, after losing the squeezing of the upper pressure plate 401, is reset to the side of the piston rod 404 under the elastic force of the spring 405, and the waste pipe 701 is closed again until the equipment returns to its initial state.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or modifications within the technical scope disclosed by the present invention; according to the technical plan and its improved conception of the present invention, all of which should be included under the protection of the present invention.
