Technical Field
[0001] This invention belongs to the field of protease separation and purification technology, specifically relating to a high-efficiency protease rapid separation and purification device. Background Technology
[0002] In the field of biotechnology, the isolation and purification of probiotic proteases is an important task. With the deepening of research on probiotics and the expansion of their applications in industries such as medicine and food, the demand for efficient, rapid, and accurate protease isolation and purification devices is increasing.
[0003] A search revealed a patent in the relevant field with publication number CN215328032U, entitled "A Rapid Separation and Purification Device for Plant Proteases." While this device facilitates the removal of the supernatant from the centrifuge and repeated rinsing with water for purification, it lacks a suitable built-in filtration structure. Filtration of the supernatant requires transferring it to another filtration device, which not only increases the number of steps but also easily introduces new contaminants, affecting the purity of the protease. Therefore, this paper proposes a high-efficiency rapid separation and purification device for probiotic proteases to address these technical problems. Utility Model Content
[0004] In existing rapid separation and purification devices for plant proteases, the supernatant needs to be transferred to another filtration device during filtration, which poses a risk of supernatant contamination and affects protease purity. This invention addresses this issue with a high-efficiency rapid separation and purification device for probiotic proteases. After centrifugation of the probiotic protease solution in the centrifuge tube, water is injected through a rinsing plate to rinse the supernatant and raise its level. Impurities are blocked by the filter membrane, and the filtered supernatant, located above the perforated plate, can be easily extracted via pump A and the extraction tube. This design completes separation, purification, and filtration within the centrifuge tube, significantly reducing the risk of supernatant contamination and ensuring protease purity, unlike existing rapid separation and purification devices that require transferring the supernatant to other filtration devices. In terms of time efficiency, omitting the supernatant transfer step greatly shortens operation time and improves separation and purification efficiency. Furthermore, the optimized design allows rinsing, filtration, and extraction to occur simultaneously, reducing connection time and errors, and enhancing process stability and reliability. The specific technical solution is as follows:
[0005] A high-efficiency probiotic rapid separation and purification device includes a base. Two arc-shaped side plates are symmetrically fixedly installed on the upper surface of the base. A centrifuge cylinder with a discharge pipe with a valve at the bottom is rotatably installed between the two arc-shaped side plates. Support plates are fixedly installed on the opposite surfaces of the two arc-shaped side plates. Hydraulic telescopic rods are fixedly installed on the upper surfaces of the support plates. A top plate is fixedly installed between the upper surfaces of the two hydraulic telescopic rods. The top plate is located above the arc-shaped side plates, and a rinsing plate is fixedly installed on the lower surface of the top plate. Multiple hanging rods are installed below the rinsing plate.

A pump body A is fixedly installed on the upper surface of the top plate. A liquid extraction pipe is connected to the inlet end of the pump body A. The liquid extraction pipe passes through the rinsing plate and is located above the perforated plate. A liquid collection pipe is connected to the outlet end of the pump body A.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figure 1-Figure 5 This utility model provides a technical solution:
[0022] A high-efficiency probiotic protease rapid separation and purification device includes a base 1. Two arc-shaped side plates 11 are symmetrically fixedly installed on the upper surface of the base 1. A centrifuge cylinder 2 with a valved discharge pipe 22 at the bottom is rotatably installed between the two arc-shaped side plates 11. Support plates 3 are fixedly installed on the opposite surfaces of the two arc-shaped side plates 11. Hydraulic telescopic rods 4 are fixedly installed on the upper surfaces of the support plates 3. A top plate 41 is fixedly installed between the upper surfaces of the two hydraulic telescopic rods 4. The top plate 41 is located above the arc-shaped side plates 11, and the lower surface of the top plate 41 is fixed. A rinsing plate 5 is installed, and multiple hanging rods 52 are installed below the rinsing plate 5. A perforated plate 53 is fixedly installed between the lower surfaces of the multiple hanging rods 52. A filter membrane 54 is detachably installed inside the perforated plate 53. A rubber ring 56 is detachably installed on the outer surface of the perforated plate 53. The outer surface of the rubber ring 56 is in contact with the inner surface of the centrifuge cylinder 2. The setting of the rubber ring 56 ensures a tight fit between the perforated plate 53 and the centrifuge cylinder 2, ensuring that when the supernatant moves upward, it can pass through the filter membrane 54 to reach the top of the perforated plate 53, thus ensuring the filtration effect of the supernatant.
[0023] A pump body A6 is fixedly installed on the upper surface of the top plate 41. The inlet end of the pump body A6 is connected to a suction pipe 61. The suction pipe 61 passes through the flushing plate 5 and is located above the hollow plate 53. The outlet end of the pump body A6 is connected to a liquid collection pipe 62.
[0024] In use, the hydraulic telescopic rod 4 extends, causing the top plate 41 and its components below it—the rinsing plate 5, the hanging rod 52, the perforated plate 53, and the filter membrane 54—to move out of the centrifuge cylinder 2. The probiotic protease liquid to be separated and purified, along with the reaction agent, is then placed into the centrifuge cylinder 2. Afterward, the hydraulic telescopic rod 4 retracts to reset the top plate 41. The rotation of the centrifuge cylinder 2 then accelerates the reaction of the probiotic protease liquid, placing it in the supernatant. Simultaneously, the rinsing plate 5 continuously injects clean water into the centrifuge cylinder 2, which first contacts the supernatant to further react with the probiotic protease. During the cleaning process, the supernatant level rises. As it rises, the supernatant is filtered through the filter membrane 54. After that, stop injecting water into the centrifuge cylinder 2, start the pump body A6, and use the liquid extraction pipe 61 to extract the supernatant from the centrifuge cylinder 2. The remaining liquid in the centrifuge cylinder 2 needs to be discharged by opening the discharge pipe 22 with a valve. During use, since water is injected into the centrifuge cylinder 2 using the flushing plate 5, the filter membrane 54 can be backwashed using the flushing plate 5 when injecting water or when discharging the remaining waste in the centrifuge cylinder 2, thereby solving the problem of cleaning when it is clogged.
[0025] It should be noted that the lower surface of the rinsing plate 5 is provided with multiple rinsing holes, and the water inlet end of the rinsing plate 5 is connected to the water inlet pipe 51. The upper surface of the top plate 41 is fixedly installed with a pump body B7. The drain end of the pump body B7 is connected to the water inlet pipe 51. The water inlet end of the pump body B7 is connected to a water source pipe 71. The water source pipe 71 is connected to an external water tank. The pump body B7 uses the water source pipe 71 to supply clean water from the external water tank into the rinsing plate 5 through the water inlet pipe 51. Water is sprayed out from the rinsing holes to inject water or to rinse the filter membrane 54.
[0026] To facilitate the replacement of filter membrane 54, such as Figure 4 As shown, the lower surface of the perforated plate 53 has an installation groove, and the outer surface of the perforated plate 53 is screwed with a support ring 55. The support ring 55 clamps and fixes the filter membrane 54 in the installation groove. When replacing the filter membrane 54, first move the perforated plate 53 out of the centrifuge cylinder 2 as a whole through the hydraulic telescopic rod 4. Then, rotate the support ring 55 to separate it from the perforated plate 53, and the filter membrane 54 can be removed for replacement. When installing the filter membrane 54, the operation is reversed.
[0027] To enhance the stability of centrifuge tube 2 during rotation, such as Figure 4 As shown, multiple steel ball bearings 57 are equidistantly embedded and rotatably installed on the outer surface of the rinsing plate 5. The outer surface of the steel ball bearings 57 is in contact with the inner surface of the centrifuge cylinder 2. With the help of the position of the rinsing plate 5, the centrifuge cylinder 2 can be limited without affecting its rotation, thus preventing it from shaking during rotation and enhancing its stability.
[0028] Specifically, such as Figure 4 As shown, the outer surface of the perforated plate 53 is integrally formed with a raised rib 531, and the rubber ring 56 is sleeved on the outer surface of the raised rib 531. The rubber ring 56 is sleeved on the outer surface of the perforated plate 53 through the raised rib 531.
[0029] Specifically, a motor 21 is fixedly installed on the upper surface of the base 1, and the output end of the motor 21 is fixedly connected to the center of the lower surface of the centrifuge tube 2. The centrifuge tube 2 rotates by being driven by the motor 21.
[0030] Finally, to facilitate observation of the liquid inside centrifuge tube 2 and to facilitate timely extraction of the supernatant, such as... Figure 1 or Figure 2 As shown, an observation window 23 is provided through the front surface of the centrifuge tube 2. A transparent glass is sealed inside the observation window 23, allowing real-time observation of the liquid level inside the centrifuge tube 2, which facilitates timely extraction of the supernatant.
