Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to an adjustable refrigerated centrifuge for microbial strains. Background Technology

[0002] Microbial strains are typically cultured and multiplied in a culture medium, and then centrifuged to isolate the target microorganism. During centrifugation, microorganisms, along with other cells or impurities, are separated based on density differences, thus obtaining the desired microbial sample. When long-term preservation of microorganisms is required, a refrigerated centrifuge may be used for both centrifugation and cryopreservation.

[0003] However, the process of loading and unloading materials in centrifuges takes a lot of time, which causes the cold air inside the centrifuge to evaporate quickly when it is turned on, reducing the freezing effect on microbial strains. To address this problem, we propose an adjustable refrigerated centrifuge for microbial strains. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an adjustable refrigerated centrifuge for microbial strains.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable refrigerated centrifuge for microbial strains, comprising a housing, a motor, a support plate, a sleeve support tube, and a one-way valve tube. A bearing seat is embedded inside the support plate, and a support tube is rotatably installed inside the bearing seat. A gear ring is sleeved on the outer wall of the support tube. A gear that meshes with the gear ring is provided at the output end of the motor. A first sealing ring is embedded inside the support tube, and a cold air pipe is slidably inserted inside the first sealing ring. A one-way valve tube that is slidably inserted inside a second sealing ring is provided at the lower end of the housing, and a top cover is provided at the upper end of the housing.

[0006] Preferably, brackets are provided on both sides of the lower end of the support plate, and mounting holes are provided inside the brackets. The brackets support the lower sides of the support plate, and the brackets are installed and fixed through the mounting holes.

[0007] Preferably, the lower end of the top cover is provided with a rotating shaft that is rotatably mounted on one side of the upper end of the box body, and both the top cover and the outer wall of the box body are provided with mating blocks. The top cover is rotatably supported at the upper end of the box body through the rotating shaft.

[0008] Preferably, a retaining sleeve is snapped onto the outer wall of the mating block, and a connecting block is provided at one end of the housing. A spring connects the connecting block and the retaining sleeve. The retaining sleeve is elastically supported on one side of the connecting block by the spring, and thus elastically snapped onto the outside of the mating block.

[0009] Preferably, a sleeve is fitted onto the outer wall of the support tube, and a mounting ring is fitted onto the outer wall of the one-way valve tube. Both the sleeve and the mounting ring have threaded holes on their inner walls, and bolts are threaded into these holes. The bolts are rotated and inserted into the threaded holes to fix the sleeve and the mounting ring, thus connecting the one-way valve tube connected to the mounting ring and the support tube connected to the sleeve together.

[0010] Preferably, a second mounting ring is fitted onto the outer wall of the one-way valve tube, and a retaining ring is fitted onto the outer wall of the support tube. The retaining ring has positioning holes arranged in a circular array inside. A positioning rod, also arranged in a circular array and slidably inserted into the positioning holes, is located at the lower end of the second mounting ring. After the positioning rod is inserted into the positioning hole, the second mounting ring aligns with the retaining ring, thus connecting the second mounting ring to the one-way valve tube. The support tube is then connected to the retaining ring, achieving the connection between the one-way valve tube and the support tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, the box body and the support tube are connected. The support tube achieves transmission through the meshing of gears and gear rings, thereby transferring the rotational force of the support tube to the inside of the box body. The microbial inoculum reagent tubes stored inside the box body are separated into target microorganisms under centrifugation. Cold air is then delivered into the box body through a cold air pipe, providing cooling during the centrifugation separation of the microbial inoculum and thus storing it. Because the box body and the support tube are connected and installed, they can be directly disassembled, avoiding the problem of the top cover being open for a long time. The separated microbial inoculum is effectively stored. Through the cooperation of multiple boxes, the feeding and unloading can be separated from the centrifuge processing, improving processing efficiency. Attached Figure Description

[0019] 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.

[0020] like Figures 1-5 As shown, the present invention proposes an adjustable refrigerated centrifuge for microbial strains, comprising a housing 3, a motor 4, a support plate 6, a sleeve 9, a support tube 10, and a one-way valve tube 12. A bearing seat 15 is embedded inside the support plate 6, and the support tube 10 is rotatably mounted inside the bearing seat 15. A gear ring 8 is sleeved on the outer wall of the support tube 10. A gear 5 that meshes with the gear ring 8 is provided at the output end of the motor 4. A sealing ring 14 is embedded inside the support tube 10, and a cold air pipe 11 is slidably inserted inside the sealing ring 14. A one-way valve tube 12 that is slidably inserted inside the sealing ring 26 is provided at the lower end of the housing 3. A top cover 1 is provided at the upper end of the housing 3.

[0021] Both sides of the lower end of the support plate 6 are provided with brackets 7, and the brackets 7 have mounting holes inside.

[0022] The top cover 1 is provided with a rotating shaft 2 that is rotatably installed on one side of the upper end of the box body 3. Both the top cover 1 and the outer wall of the box body 3 are provided with a connecting block 23.

[0023] The outer wall of the docking block 23 is fitted with a sleeve 24, and a connecting block 25 is provided at one end of the housing 3. A spring 22 connects the connecting block 25 and the sleeve 24.

[0024] A sleeve 9 is fitted onto the outer wall of the support tube 10, and an installation ring 13 is fitted onto the outer wall of the one-way valve tube 12. Both the sleeve 9 and the installation ring 13 have screw holes 20 on their inner walls, and bolts 21 are installed inside the screw holes 20.

[0025] A mounting ring 17 is sleeved on the outer wall of the one-way valve pipe 12, and a retaining ring 18 is sleeved on the outer wall of the support pipe 10. The retaining ring 18 has positioning holes 19 arranged in a ring array inside. A positioning rod 16 arranged in a ring array and slidably inserted into the positioning hole 19 is provided at the lower end of the mounting ring 17.

[0026] Based on the implementation steps of Example 1: Motor 4 drives gear 5 to rotate, thereby applying a pushing force to gear ring 8. Gear ring 8 drives support tube 10 to rotate. Because support tube 10 is supported by bearing seat 15, it drives box 3 to rotate. When box 3 rotates, the reagent bottle containing microbial strains inside rotates synchronously. It is worth noting that the reagent bottle needs to be fixed inside box 3 to avoid collision. Under the action of centrifugal force, the microbial sample or solution to be processed is placed into sample tube or centrifuge tube. The sample tube is installed in box 3. Support tube 10 is equivalent to the rotor of centrifuge. The sample tube is indirectly connected to the centrifuge rotor. Rotation of box 3 is equivalent to starting centrifuge. This causes chamber 3 to rotate, and the sample will generate centrifugal force under high-speed rotation, causing microorganisms and other components to separate. At the same time, the cold air pipe 11 is connected to the refrigeration system, which provides low-temperature gas, which enters the support pipe 10 under pressure, and then enters the chamber 3 through the one-way valve pipe 12. The one-way valve pipe 12 is equipped with a one-way valve, which opens under pressure and closes automatically when the pressurization ends, so that the microbial precipitate can be quickly frozen and preserved while centrifuging. After an appropriate centrifugation time, the centrifuge is stopped, and the microbial precipitate or supernatant is taken out for further processing or frozen preservation.

[0027] The above material handling process avoids the direct opening of the top cover 1 because the one-way valve inside the one-way valve pipe 12 prevents the leakage of cold air inside the box 3. By grasping the bolt 21 and unscrewing the bolt 21 out of the screw hole 20, the sleeve 9 is fixed with the mounting ring 13. Then the box 3 is lifted upward, which causes the positioning rod 16 to move out of the positioning hole 19. The sealing ring 26 at the one-way separation sliding extraction point, because the sealing ring 26 is slidably installed with the one-way valve pipe 12, avoids sealing the gap between the one-way valve pipe 12 and the support pipe 10 when cold air passes through, thereby allowing the cold air to be squeezed into the one-way valve pipe 12 and enter the box 3.

[0028] This avoids the leakage of internal cold air when the chamber 3 is opened directly. The chamber 3 is directly transported, and then the elastic engagement with the docking block 23 is ended by pulling the sleeve 24 and squeezing the spring 22. The top cover 1 opens the upper end of the chamber 3 through the rotating shaft 2. After the chamber 3 is opened, the sample tube is stored and retrieved. During the storage and retrieval process, the same chamber 3 is connected to the support tube 10 to realize the separation of microbial strains. After the microbial strains are separated, they are refrigerated and preserved. The storage and retrieval of materials are separated from the equipment processing, which improves the separation and processing efficiency in the large-scale separation and processing process.

[0029] It is worth noting that the one-way valve includes a valve body, a valve core, and a valve spring. The valve body is the main body of the one-way valve tube 12. The valve core and valve spring are installed in the valve body. The valve body is the main part that houses the necessary components of the one-way valve and provides the connection interface. The valve core is the core component that controls the flow of the medium, usually a valve or ball. The valve spring is a pressure-acting element used to keep the valve core in the closed or open state. A valve seat and a support ring are also provided inside the valve body. The support ring supports the valve spring and snaps the elastically installed valve core into the valve seat. Both the valve seat and the support ring are hollow inside. The sealing ring 26 is slidably installed with the one-way valve tube 12, which can effectively prevent... To prevent cold air leakage and maintain a stable low-temperature environment inside the centrifuge chamber 3 during operation, the sealing ring 26, due to its sliding connection with the one-way valve pipe 12, exhibits good wear resistance during operation, extending its service life. The design of the sealing ring 26 effectively prevents other substances besides cold air from entering the one-way valve pipe 12, ensuring the purity of system operation. Its structure is relatively simple, and replacement and maintenance are relatively easy, reducing equipment maintenance costs. The sealing ring 26 is usually made of wear-resistant materials or has a special surface treatment, possessing certain adsorption and lubrication properties, reducing friction in contact with it, and improving sealing effect and stability.
