Description

Technical Field

[0001] This invention belongs to the field of biological reagent storage technology, specifically, it relates to a liquid polypeptide storage tank with a leak-proof and polypeptide stability protection structure. Background Technology

[0002] Peptides are small molecule compounds with biological activity formed by multiple amino acids linked by peptide bonds. They are widely used in pharmaceutical research and development, clinical diagnosis, bioengineering and other fields. During storage and transportation, the stability of liquid peptide solutions is easily affected by external environmental factors, such as temperature fluctuations, oxygen oxidation, and microbial contamination, which may lead to the destruction of peptide molecular structure and loss of activity, thereby affecting their application effect. Existing liquid peptide storage tanks mostly use a single sealing ring or threaded seal. After long-term use, leakage is likely to occur due to aging of the seals and assembly errors. The risk of leakage increases significantly, especially during transportation or pressure changes, resulting in peptide loss and cross-contamination. Furthermore, the storage tanks lack a targeted stability protection mechanism, making peptides prone to precipitation due to low-temperature instability, oxidative degradation, or uneven local concentration, which makes it difficult to meet the requirements for long-term storage. To address the aforementioned issues, this application proposes a liquid polypeptide storage tank with a leak-proof and polypeptide stability protection structure. Utility Model Content

The side of the protective shell 101 near the storage tank 104 is in contact with the insulation layer 103. A liquid inlet 108 is provided on the top of the protective shell 101. The sealing component 2 on the top of the tank body 1 can prevent peptide leakage and effectively protect the peptide stored inside the tank body 1. Nitrogen gas is filled inside the storage tank 104 to prevent the peptide from contacting oxygen, thus effectively protecting the peptide. The sealing component 2 on the top of the liquid inlet 108 can seal the tank body 1, thereby effectively protecting the peptide and preventing leakage.

[0015] Reference Figure 4 A support column 105 is fixedly connected to the inner bottom of the protective shell 101. A limiting ring 106 is fixedly connected to the side of the support column 105 near the storage container 104. The inner side wall of the limiting ring 106 is in contact with the bottom of the storage container 104. The limiting ring 106 is supported by the support column 105 fixedly connected to the inner bottom of the protective shell 101. The limiting ring 106 is in contact with the bottom of the storage container 104, which can effectively support the storage container 104 and prevent the storage container 104 from shaking.

[0016] Reference Figure 1-2 The outer wall of the protective shell 101 is provided with an air extraction port 107, which is connected to the isolation tank 102. The end of the air extraction port 107 away from the protective shell 101 is provided with a flange. The gas in the isolation tank 102 is extracted through the air extraction port 107 installed on the outer wall of the protective shell 101, so that the inside of the isolation tank 102 tends to be a vacuum state, thereby effectively keeping the storage tank 104 warm.

[0017] Reference Figure 2The sealing assembly 2 includes a can lid 201 that fits against the outer wall of the liquid inlet 108. A sealing plug 202 is fixedly connected to the bottom center of the can lid 201. The outer wall of the sealing plug 202 is adapted to the inner wall of the liquid inlet 108. A threaded groove 203 is provided on the outer wall of the liquid inlet 108. The can lid 201 can be threadedly connected to the outer wall of the liquid inlet 108 through the threaded groove 203 on the outer wall of the liquid inlet 108 and the can lid 201, so that the sealing plug 202 can enter the interior of the liquid inlet 108 to seal it, thereby preventing peptide leakage.

[0018] Reference Figure 3 The can lid 201 is threadedly connected to the liquid inlet 108 via the threaded groove 203. A sealing ring 212 and a sealing gasket 213 are fixedly connected to the inner wall of the liquid inlet 108. The sealing ring 212 and the sealing gasket 213 installed on the inner wall of the liquid inlet 108 fit together with the sealing plug 202, which can effectively seal the liquid inlet 108, preventing oxygen from entering and effectively preventing peptide leakage.

[0019] Reference Figure 3 An expansion groove 204 is provided on the inner wall of the liquid inlet 108. A first spring 205 is fixedly connected inside the liquid inlet 108. An inclined block 206 is fixedly connected to the end of the first spring 205 away from the liquid inlet 108. A squeezing column 207 is fixedly connected to the top of the inclined block 206. A positioning frame 208 is attached to the bottom of the inclined block 206. A second spring 209 is fixedly connected to the inner wall of the positioning frame 208. A positioning plate 210 is fixedly connected to the end of the second spring 209 away from the positioning frame 208. The positioning plate 210 is connected to the liquid inlet... The inlet 108 is fixedly connected, and the inner wall of the inlet 108 is provided with a telescopic opening 211. By rotating the sealing plug 202, the sealing plug 202 squeezes the extrusion column 207, thereby squeezing the positioning frame 208 by the extrusion column 207 and the inclined block 206. The positioning frame 208 moves into the inlet 108 through the telescopic opening 211, thereby squeezing the sealing plug 202 and keeping the sealing plug 202 stable. This allows the sealing assembly 2 to better seal the tank 1, thereby preventing the leakage of peptides.

[0020] Working principle: By injecting the polypeptide into the storage tank 104, which is filled with nitrogen, and inserting the tank lid 201 and sealing plug 202 into the liquid inlet 108, the tank lid 201 compresses the extrusion column 207. This causes the extrusion column 207 and the inclined block 206 to compress the positioning frame 208, thereby moving the positioning frame 208 into the liquid inlet 108 through the telescopic port 211. This allows the positioning frame 208 to compress and fix the sealing plug 202, preventing... If the can lid 201 becomes loose, the sealing plug 202, after entering the inlet 108, will press and adhere to the sealing ring 212 and the sealing gasket 213, thereby effectively sealing the inside of the storage tank 104 and preventing oxygen from entering the storage tank 104. An insulation layer 103 is provided between the protective shell 101 and the storage tank 104, and the gas inside the isolation tank 102 is extracted, making the inside of the isolation tank 102 approach a vacuum state, which can effectively keep the peptides inside the storage tank 104 warm, thereby making the peptides more stable.
