Description

Technical Field

[0001] The utility model relates to the field of nitrogen production equipment, and in particular to high-purity nitrogen production equipment. Background Art

[0002] In nature, nitrogen is the most abundant element in the air, accounting for about 78% of the volume of air. It mainly exists in the atmosphere in the form of single molecular nitrogen. It is a colorless, tasteless, and odorless gas with relatively stable chemical properties. It is not easy to react chemically with other substances. Nitrogen is one of the indispensable elements in living organisms and one of the basic elements of amino acids. It is essential for the growth and development of organisms. At the same time, nitrogen and its compounds are also widely used in industrial and agricultural production, such as in the manufacture of fertilizers, nitric acid, ammonia, etc. It is an important foundation for the development of modern agriculture and industry. When extracting nitrogen, nitrogen production equipment is needed.

[0003] The prior art with patent publication (announcement) number CN219663648U discloses a high-purity nitrogen production equipment, including a bracket, a shell is fixedly assembled in the middle of the bracket, a sealing plate is fixedly assembled on the top of the shell, a movable groove is opened on the top of the sealing plate, a turntable is rotatably connected to the inner wall of the movable groove, a material injection hole is opened on the top of the turntable, a rotating motor is fixedly connected to the outer wall of the bracket, a rotating gear is fixedly arranged on the output shaft of the rotating motor, a mounting groove is opened in the middle of the bracket, a stirring motor is fixedly assembled on the inner wall of the mounting groove, a discharge pipe is penetrated through the inner wall of the mounting groove until the bottom of the bracket, a stirring rod is fixedly sleeved on the output shaft of the stirring motor, a collecting box and a material guide pipe are respectively fixedly arranged on the outer edges of the stirring rod, a limiting shell is fixedly arranged on the outer wall of the collecting box, a stirring blade is fixedly arranged on the end of the material guide pipe, a straight tube is penetrated through the top of the sealing plate until the inner wall of the bracket, and a material collection hub is fixedly arranged at the bottom end of the straight tube.

[0004] The above patent document discloses a high-purity nitrogen production equipment. Although it can solve the problem that both the injection mechanism and the air intake mechanism are in the outside world, which leads to an increase in the contact time between the outside air and dust and the two, and thus makes the equipment susceptible to contamination, at the same time, there is no stirring mechanism in the equipment, and the raw materials can only be liquefied and flowed by heating, thereby increasing the production cost of nitrogen for the equipment. However, the disadvantage is that after the reactants are thrown into the shell, the residue will remain on the inner wall of the shell, making it inconvenient to clean the inside of the shell after use, and the raw materials are thrown out by the stirring blades, which will inevitably cause blockage, affecting the normal use of the equipment.

[0005] Therefore, we have made improvements to this and proposed a high-purity nitrogen production equipment. Utility Model Content
