Description

Technical Field

[0001] The utility model relates to the technical field of biological enzyme separation, and more specifically to a microfiltration purification and separation device for yeast hydrolysis biological enzyme liquid. Background Art

[0002] Biological enzymes are organic substances with catalytic effects produced by living cells. When preparing biological enzymes, the biological enzymes extracted from the culture medium need to be purified by microfiltration in order to obtain biological enzymes with higher purity. The purification and separation process is the process of purifying and separating a mixture into two or more products with different compositions through physical, chemical or biological means, or a combination of these methods. In layman's terms, it is to separate a certain substance or a certain type of substance from a complex mixture, and make it exist in a relatively pure form through purification technology. The purification and separation process runs through the entire production process and is an important means to obtain the final product.

[0003] Chinese Patent Authorization Announcement No.: CN211999688U discloses a yeast hydrolysis enzyme liquid microfiltration purification separation device, which is provided with a separation box, which is movably connected to a centrifugal chamber inside. The motor is turned on, and the shaft rotates, driving the connecting plate, the separation box and the centrifugal chamber to rotate. During the rotation, the liquid inside the centrifugal chamber will move toward the separation box due to the centrifugal force, so that the microfiltration membrane can perform microfiltration separation on the liquid, leaving impurities inside the centrifugal chamber, and the solenoid valve on the discharge pipe is opened to facilitate the removal of the separated liquid.

[0004] When yeast hydrolyzed enzyme liquid is continuously microfiltered and purified, since the pores of the microfiltration membrane are very small, as the operation time increases, the microbial cells, proteins, particulate matter, etc. in the culture medium gradually accumulate on the membrane surface, causing the membrane pores to become clogged, which reduces the filtration efficiency and increases the operating pressure, ultimately requiring the operation to be stopped for cleaning or replacement of the microfiltration membrane.

[0005] Therefore, in view of the above problems, a yeast hydrolysis enzyme liquid microfiltration purification and separation device is proposed. Utility Model Content

The liquid is microfiltered and separated by a microfiltration membrane. While the separation barrel rotates, the microfiltration membrane can undergo continuous tiny vibrations and deformations, so that the particles and impurities on the microfiltration membrane can be effectively removed, thereby reducing the risk of clogging and improving the microfiltration separation efficiency.

[0033] Example:

[0034] See also Figure 1-2 , a yeast hydrolysis enzyme liquid microfiltration purification separation device, comprising a treatment box 1, a cover plate 2 is detachably installed on the top of the treatment box 1, a liquid inlet pipe 3 is installed on the top of the cover plate 2, the top of the treatment box 1 is open, the liquid inlet pipe 3 is connected to the treatment box 1, the bottom of the treatment box 1 is fixedly connected to a discharge pipe 4 connected thereto, and a separation component 5 is arranged inside the treatment box 1;

[0035] The separation assembly 5 includes a separation barrel 51 and a motor 52. The separation barrel 51 is located in the inner cavity of the treatment box 1, and a plurality of evenly distributed installation grooves are opened at the outer end of the separation barrel 51. A microfiltration membrane 53 is installed in the installation groove. The motor 52 is fixed to the bottom end of the treatment box 1, and the output end of the motor 52 passes through the treatment box 1 and is fixedly connected to the separation barrel 51.

[0036] This solution is used for separating and purifying yeast hydrolysis enzymes. The impurities, microbial cells and other solid particles in the yeast hydrolysis enzyme liquid are separated by microfiltration technology, so as to obtain relatively pure yeast hydrolysis enzymes.

[0037] Specifically, the yeast hydrolyzing enzyme liquid is injected into the separation barrel 51 through the liquid inlet pipe 3, and the separation barrel 51 is controlled to rotate by the motor 52. The liquid inside the separation barrel 51 undergoes centrifugal motion, and the liquid is microfiltered and separated by the microfiltration membrane 53, so that impurities remain inside the separation barrel 51. The separated relatively pure yeast hydrolyzing enzyme falls into the bottom of the inner cavity of the processing box 1 and is discharged through the discharge pipe 4.

[0038] The cover plate 2 is fixed to the top of the processing box 1 by screws, so that the cover plate 2 can be detached, thereby facilitating the cleaning of impurities trapped in the separation barrel 51 at a later stage.

[0039] See also Figure 2 The top of the separation barrel 51 is fixedly connected with a connecting block 55, the top of the connecting block 55 is fixedly connected with an annular block, the top of the inner wall of the processing box 1 is provided with an annular groove matching the annular block, and the annular block is slidably connected with the annular groove.

[0040] In this embodiment, the stability of the separation barrel 51 during rotation can be improved through the cooperation between the annular block and the annular slide groove.

[0041] See also Figure 2-3 The outer surrounding of the separation barrel 51 is fixedly connected with a plurality of connecting rings 54, the outer end of the microfiltration membrane 53 is fixedly connected with a plurality of sliding rods 57, the sliding rods 57 penetrate the connecting ring 54 and are slidably connected with the connecting ring 54, the end of the sliding rod 57 away from the microfiltration membrane 53 is fixedly connected with a fixed block 58, and the end of the fixed block 58 away from the sliding rod 57 is rotatably connected with a roller 59, the inner wall of the processing box 1 is fixedly connected with a plurality of protrusions 6, the plurality of protrusions 6 are arranged in a ring shape with equal distances, and the cross-section of the protrusions 6 is arranged in a semicircular shape, and the outer surrounding sleeve of the sliding rod 57 is provided with a spring 56, and the two ends of the spring 56 are respectively fixedly connected to the fixed block 58 and the connecting ring 54.

[0042] In this embodiment, while the separation barrel 51 rotates, it can synchronously drive the connecting ring 54 to rotate, thereby driving the fixed block 58 and the roller 59 at one end to perform circular motion. Since the multiple protrusions 6 are arranged in a ring with equal spacing, when the roller 59 contacts the protrusion 6, the roller 59 is squeezed by the protrusion 6 and drives the slide bar 57 to move. Since the slide bar 57 and the microfiltration membrane 53 are fixedly connected, the microfiltration membrane 53 can be deformed. When the roller 59 moves between adjacent protrusions 6, the spring 56 can control the movement of the slide bar 57 by its own elastic force, so that the microfiltration membrane 53 is reset. As the separation barrel 51 continues to rotate, the multiple slide bars 57 perform reciprocating piston motion, so that the microfiltration membrane 53 is continuously vibrated and deformed, and the particles and impurities on the microfiltration membrane 53 can be effectively removed, thereby reducing the risk of blockage.

[0043] It should be noted that the microfiltration membrane 53 is made of polymer materials, such as polyester, polypropylene, polyethersulfone, etc. These materials are tough to a certain extent. These polymer materials have good elasticity and deformability. The microfiltration membrane 53 can be deformed to a certain extent by external forces and then return to its original state.

[0044] Working principle: yeast hydrolysis enzyme liquid is injected into the separation barrel 51 through the liquid inlet pipe 3, and the separation barrel 51 is controlled to rotate by the motor 52. The liquid inside the separation barrel 51 undergoes centrifugal motion, and the liquid is microfiltered and separated by the microfiltration membrane 53, so that impurities remain inside the separation barrel 51, and the separated relatively pure yeast hydrolysis enzyme falls into the bottom of the inner cavity of the processing box 1 and is discharged through the discharge pipe 4. When the separation barrel 51 rotates, it can synchronously drive the connecting ring 54 to rotate, thereby driving the fixed block 58 and the roller 59 at one end to perform circular motion. The roller 59 is squeezed by the protrusion 6 to drive the slide bar 57 to move, so that the microfiltration membrane 53 can be deformed. When the roller 59 moves between adjacent protrusions 6, the spring 56 can control the movement of the slide bar 57 by its own elastic force, so that the microfiltration membrane 53 is reset. With the continuous rotation of the separation barrel 51, multiple slide bars 57 are realized to perform reciprocating piston motion, so that the microfiltration membrane 53 continues to vibrate slightly, reducing the probability of clogging of the microfiltration membrane 53.

[0045] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
