Description

Technical Field

[0001] The utility model relates to the technical field of cytosine storage, in particular to a low-temperature storage tank for cytosine production and processing. Background Art

[0002] Cytosine is an organic compound with the chemical formula C5H6N2O2, which belongs to the pyrimidine class of compounds. Cytosine plays an important biological role in organisms and is one of the important components of DNA and RNA. In DNA, cytosine and adenine correspond to each other, and they pair with each other through hydrogen bonds to form the double helix structure of DNA. The existence of cytosine plays a vital role in maintaining the genetic information transmission and cell function of organisms. Cytosine needs to be stored in a low temperature environment.

[0003] For example, the Chinese invention patent with the announcement number CN103350835A discloses a storage tank, comprising: a tank body; a feed port, which is arranged at the feed end of the tank body and has a first valve; a first secondary channel, which is connected to the feed port; a first ejection device, which is arranged in the first secondary channel and can be slidably sealed with the inner wall of the first secondary channel, and by pushing the first ejection device, the internal air is compressed to push the material in the feed port into the tank body; a discharge port, which is arranged at the discharge end of the tank body and has a second valve; a second channel, which is connected to the feed port; a second ejection device, which is arranged in the second secondary channel and can be slidably sealed with the inner wall of the second secondary channel, and by pushing the second ejection device, the internal air is compressed to push the material in the discharge port into the tank body;

[0004] The above scheme has the following problems: the device can prevent the material from failing when in use and will not cause blockage to the pipeline; however, if applied to cytosine, the device cannot effectively keep the inside of the storage tank in a low temperature state, and cannot control the pressure inside the storage tank and relieve the pressure, and the safety needs to be improved.

[0005] Therefore, we proposed a low-temperature storage tank for cytosine production and processing in order to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the utility model is to provide a low-temperature storage tank for cytosine production and processing, so as to solve the problem that the storage tanks on the current market cannot maintain low temperature and are not safe, as mentioned in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-temperature storage tank for cytosine production and processing, comprising a tank body and a mounting seat; the tank body is arranged above the mounting seat; the tank body is fixedly connected to the mounting seat; the tank body adopts a multi-layer design, including a protective layer and an insulating layer; the insulating layer is arranged between the protective layers; the protective layer is a double-layer design; stainless steel is selected as the main material of the protective layer; polyurethane foam is selected as the main material of the insulating layer; and a corrosion-resistant coating is coated on the protective layer inside the tank body.

[0008] The above technical solution can improve the insulation performance and reduce energy loss by adopting a double-layer stainless steel structure with insulation material filled in the middle.

[0009] As a preferred technical solution of the utility model, an airbag is provided inside the tank body; the airbag is fixedly installed inside the tank body; the airbag is suspended at the upper end of the tank body; the airbag is fixedly connected to the tank body; an air outlet is provided at the upper end of the airbag; the bottom of the air outlet is the airbag; the upper end opening is connected to the air cylinder; the air cylinder passes through the tank body; and the uppermost end of the air cylinder is provided above the tank body.

[0010] By adopting the above technical solution, the air pressure inside the tank can be sensed through the air bag, and the pressure inside the tank can be relieved through the air cylinder.

[0011] As a preferred technical solution of the utility model, a push plate is provided at the connection between the bottom of the air cylinder and the air outlet; the push plate is slidably connected to the air cylinder; sliding grooves are provided on both sides of the air cylinder; and both ends of the push plate are engaged in the sliding grooves.

[0012] By adopting the technical solution, the push plate can be squeezed by the deflation of the airbag so that the push plate slides upward in the air cylinder.

[0013] As a preferred technical solution of the utility model, a first spring is provided on the upper end of the push plate; the first spring is fixedly connected to the push plate.

[0014] The above technical solution can adjust the acceptable internal pressure through the first spring.

[0015] As a preferred technical solution of the utility model, a push rod is arranged on the top of the first spring; the first spring is fixedly connected to the push rod; the push rod and the first spring are both arranged inside the air cylinder; the top end of the push rod is a pressure relief port; the pressure relief port is embedded in the top plate.

[0016] The above technical solution can enable the push rod to push out the top plate when the first spring cannot shrink, thereby relieving the pressure inside the tank body.

[0018] By adopting the above technical solution, the tank body can be sealed without pressure relief through the contraction of the second spring.

[0019] As a preferred technical solution of the present utility model, the tank body is spherical as a whole.

[0020] The above technical solution can increase structural strength, reduce stress concentration and improve pressure resistance by adopting a spherical design.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 1. The utility model is provided with a protective layer and an insulating layer. By adopting a double-layer stainless steel structure and filling the middle with insulating materials, the thermal insulation performance is improved and energy loss is reduced, thereby ensuring that the interior of the storage tank is always in a low temperature state;

[0023] 2. The utility model is provided with an airbag and a pressure relief port. The air bag is squeezed by the internal air pressure of the tank body so that the gas inside the airbag is discharged into the air cylinder.
