Liquid nitrogen tank

Product description
First, the product name
Chinese name: liquid nitrogen biological container (liquid nitrogen tank)
English name: Liquid nitrogen biological container (Liquid nitrogen tank)
Second, product introduction
1. Liquid nitrogen tanks can be generally divided into liquid nitrogen storage tanks and liquid nitrogen transport tanks. Storage tanks are mainly used for static storage of indoor liquid nitrogen, and should not be used for long-distance transportation under working conditions; liquid nitrogen transport tanks have been specially designed for earthquake protection in order to meet the transportation conditions. In addition to being statically stored, it can also be used for transportation under the condition of filling liquid nitrogen, but it should also avoid violent collision and vibration.
2. Made of imported high quality anti-rust aluminum alloy, the product quality is light.
3. The inner shell of the product is formed by spinning technology, with few welds and beautiful appearance, and the vacuum leak rate is guaranteed.
4. A protective cover with a lock can be provided according to user requirements to ensure the safety of food samples stored in the container.
5. Numbered cartridges for easy identification and independent access to biological samples.
6. High-vacuum multi-layer insulation design with good low-temperature insulation performance, which can minimize the evaporation loss of liquid nitrogen (-196 °C) stored, and provide vacuum guarantee of not less than 8 years.
Third, common uses
1. Active preservation of animal semen.
It is mainly used for the preservation of semen from excellent breeds such as cattle and sheep, as well as semen from animals, as well as long-distance transportation and storage.
2. Active preservation of biological samples.
Vaccines, bacterial strains, cells, and human and animal organs in the biomedical field can be immersed in liquid nitrogen stored in a liquid nitrogen tank for long-term active storage. When it is needed, take out the thawing and rewarming and use it.
3. Cryogenic treatment of metallic materials.
The cryogenic treatment of the metal material by the liquid nitrogen stored in the liquid nitrogen tank can change the metallographic structure of the metal material and significantly improve the hardness, strength and wear resistance of the metal material.
4. Cryogenic assembly of precision parts.
After the precision parts are cryogenically treated with liquid nitrogen, assembly is performed to improve the assembly quality of the parts, thereby improving the overall performance of the equipment or the instrument.
Fourth, the packaging specifications

Fifth, the production process
1. Shell: The outer layer of the Tianchi liquid nitrogen tank is the outer shell, and the upper part is the tank mouth.
2. Inner tank: The space in the inner layer of the Tianchi liquid nitrogen tank is called the inner tank. It is generally a corrosion-resistant aluminum alloy. The bottom of the inner tank has a base for fixing the cylinder. The liquid nitrogen and samples can be stored in In the inner slot.
3. Interlayer: The interlayer refers to the gap between the inner and outer layers of the tank. It is in a vacuum state. The purpose of vacuuming is to improve the thermal insulation performance of the can, while the interlayer is provided with a heat insulating material and an adsorbent.
4. Neck tube: The neck tube is usually made of FRP material. The inner and outer layers are connected and kept to a certain length. The adsorbent is placed around the neck tube and the bottom layer. The neck of the top is specially designed. The structure must have pores to discharge the nitrogen evaporated from the liquid nitrogen to ensure safety and heat insulation to minimize the vaporization of liquid nitrogen.
5. Cover: The plug is made of plastic with good thermal insulation to prevent evaporation of liquid nitrogen while fixing the handle of the lift.
6. Lifting the bucket: The lifting cylinder is placed in the tank inner tank, in which the thin tube can be stored. The handle of the lifting cylinder is hung on the neck and fixed with a stopper.
Sixth, matters needing attention
1. Due to the large heat of the liquid nitrogen tank, the first time the liquid is filled with nitrogen, the heat balance time is longer, and it can be pre-cooled (about 60L) with a small amount of liquid nitrogen medium, and then slowly filled (so that ice is not easily formed). Blocking).
2. In order to reduce the loss of liquid nitrogen in the future, please refill the nitrogen when there is a small amount of liquid nitrogen in the liquid nitrogen tank. Or fill the liquid within 48 hours after using liquid nitrogen.
3. In order to ensure the safety and reliability of liquid nitrogen tanks, liquid nitrogen tanks can only be filled with liquid nitrogen, liquid oxygen and liquid argon.
4. When infusion, water and frost on the outer surface of the liquid nitrogen tank are normal. When the pressure increasing valve of the liquid nitrogen tank is opened for boosting operation, since the pressure coil is attached to the inner wall of the outer cylinder of the liquid nitrogen tank, the liquid nitrogen tank coil is absorbed by the liquid nitrogen. The heat of the cylinder is vaporized to achieve the purpose of boosting, and there may be spotted frost on the outer cylinder of the liquid nitrogen tank. After closing the liquid nitrogen tank booster valve, the frost point will slowly dissipate. When the liquid nitrogen tank pressure increasing valve is closed and the infusion operation is not performed, the outer surface of the liquid nitrogen tank has water and frost, which indicates that the vacuum of the liquid nitrogen tank has been destroyed, and the liquid nitrogen tank cannot be used any more. Should be looking for professional manufacturers of liquid nitrogen tanks for repair or disposal.
5. When transporting liquid nitrogen medium on the road surface of Grade III or below, please do not exceed 30km/h.
6. The vacuum nozzle on the liquid nitrogen tank, the seal of the safety valve, the seal can not be damaged.
7. If the liquid nitrogen tank is not used for a long time, drain and dry the liquid nitrogen medium inside the liquid nitrogen tank, then close all valves.
8. Before filling the liquid nitrogen tank, the liquid nitrogen tank must be dried with dry air to dry the container liner and all the valves and pipes before it can be filled with liquid nitrogen medium. Otherwise, the pipeline will be blocked by ice, which will affect the pressure rise and infusion. .
9. Liquid nitrogen tanks are instruments and meters. They should be handled with care. When opening the valves of liquid nitrogen tanks, the force should be moderate and the speed should not be too fast; especially the liquid nitrogen tank metal hose and / When the joint at the drain valve is connected, it cannot be overtightened with a strong force. It can be sealed by slightly tightening it in place (the ball head structure is easy to seal), so as to avoid twisting or even twisting the liquid nitrogen tank nozzle. Hold the liquid nitrogen tank with one hand.
Note: The above gas cylinder specifications are general reference materials. If you have special requirements, please call 40009 63336, 18563963366.
