Description

Technical Field

[0001] The invention belongs to the technical field of nitrogen generators, and in particular relates to a nitrogen generator with a storage function. Background Art

[0002] Nitrogen is a widely used inert gas. With its chemical properties and special effects, it is widely used in different fields and has become an indispensable part of various production and experimental processes. Nitrogen production requires the use of special nitrogen generator equipment. Nitrogen generators, through their efficient and environmentally friendly technology and wide range of applications, not only play an important role in environmental protection and emission reduction, but also show extensive and far-reaching influence and importance in promoting scientific and technological progress, ensuring food safety, optimizing industrial production efficiency and environmental protection. With the continuous improvement of environmental protection requirements and the rapid development of the environmental protection industry, the application prospects of nitrogen generators will be broader.

[0003] There are many types of nitrogen generators on the market, but there are some defects and deficiencies that need to be improved: (1) When using a nitrogen generator to make nitrogen, the separated and extracted nitrogen needs to be stored. The current nitrogen generator uses a gas tank to centrally store nitrogen. However, after the air compression and adsorption process, the nitrogen produced by the nitrogen generator is often at a high temperature. The existing nitrogen generator cannot cool down the gas tank that stores high-temperature nitrogen, causing the gas tank to work in a high-temperature environment for a long time, which not only affects the service life of the gas tank, but may even cause the tank to rupture or leak. and cause safety hazards; (2) the existing nitrogen generator gas tank is often fixed to the nitrogen generator by bolts and other fasteners. When disassembling and assembling, it is necessary to use tools to manually tighten or loosen the fasteners. The process is cumbersome, time-consuming and labor-intensive. The gas tank cannot be quickly disassembled and assembled, making it inconvenient to perform regular maintenance and replacement; (3) after the nitrogen generator produces nitrogen, it needs to introduce nitrogen into the gas tank through a pipeline for storage. However, the existing nitrogen generator gas tank lacks effective fixing measures. After the pipeline is connected to the gas tank, it is easy to loosen or even fall off, resulting in nitrogen leakage, which in turn causes waste. Therefore, in view of the above problems, a nitrogen generator with storage function provided by the present invention is of great significance. Summary of the invention

[0004] The present invention provides a nitrogen generator with a storage function. The prepared nitrogen can be stored through a gas storage tank. When the temperature of the nitrogen stored in the gas storage tank is high, the air flow speed around the gas storage tank can be accelerated through a cooling mechanism, so that the surface heat of the gas storage tank storing the high-temperature nitrogen can be diffused to the external air in time, thereby realizing the cooling of the gas storage tank, effectively avoiding the gas storage tank working in a high-temperature environment for a long time to affect the service life, and also preventing the tank body from rupturing or leaking to cause safety hazards; the gas storage tank can be fixed on the positioning seat through the mutual cooperation between the positioning block and the positioning groove, and when it needs to be disassembled, The hook of the external lifting device can be hooked on the lifting ring at the top of each positioning block, and the gas tank can be lifted by the lifting device and removed from the positioning seat, so that the gas tank can be quickly disassembled and assembled without the need to manually tighten or loosen the fasteners with the help of tools, which greatly simplifies the disassembly and assembly process, saves time and effort, and facilitates regular maintenance and replacement of the gas tank; nitrogen can be introduced into the gas tank along the gas delivery port through the gas delivery pipe for storage, and the gas delivery pipe can be locked and fixed in the gas delivery port through the locking piece, thereby effectively avoiding loosening or even falling off of the gas delivery pipe after being connected to the gas tank, resulting in nitrogen leakage, and in summary, solves the problems in the background technology.

[0026] (2) When the nitrogen generator with storage function of the present invention is in use, the gas storage tank can be fixed on the positioning seat by the mutual cooperation between the positioning block and the positioning groove. When it needs to be disassembled, the hook of the external lifting device can be hooked on the lifting ring on the top of each positioning block, and the gas storage tank can be lifted by the lifting device and removed from the positioning seat, so that the gas storage tank can be quickly disassembled and assembled without the need to manually tighten or loosen the fasteners with the help of tools, which greatly simplifies the disassembly and assembly process, saves time and effort, and facilitates regular maintenance and replacement of the gas storage tank;

[0049] The locking member includes a locking cylinder 33, one end of which is fixedly connected to a locking groove 34. The locking groove 34 is a circular groove structure, the bottom of which is connected to the locking cylinder 33, and the side wall of the locking groove 34 is provided with a plurality of threaded holes, and locking bolts 35 are threadedly connected in the threaded holes. A plurality of studs 36 are fixedly connected to the bottom of the locking groove 34, and nuts 37 matching therewith are threadedly connected on the studs 36. The gas pipe 11 can pass through the locking groove 34 and the locking cylinder 33 respectively and extend to the gas delivery port 20. At this time, the locking bolts 35 in each threaded hole are tightened so that the ends of the locking bolts 35 are against the pipe wall of the gas delivery pipe 11, so as to lock and fix the gas delivery pipe 11 in the gas delivery port 20, thereby effectively preventing the gas delivery pipe 11 from loosening or even falling off after being connected to the gas storage tank 16, thereby causing nitrogen to escape.

[0050] Among them, the limiting opening 15 is circular, and a protective ring 38 is provided on its inner wall surface. The protective ring 38 is circular, and a plurality of buffer blocks 39 are provided on its inner wall surface. The buffer blocks 39 are hemispherical rubber block structures.

[0052] Among them, the bottom surface of each positioning groove 29 is provided with an anti-wear pad 40, the anti-wear pad 40 is made of elastic materials such as rubber and is fixed by glue or other means. When the positioning block 18 is fitted in the positioning groove 29, the anti-wear pad 40 can be placed on the bottom of the positioning block 18 to play an anti-wear and buffering role, thereby avoiding direct contact between the bottom of the positioning block 18 and the positioning groove 29 to cause collision and wear.

[0053] Among them, the top of each positioning block 18 is fixedly connected with a reinforcing rib 41, which is triangular and one side of which is fixedly connected to the side wall of the gas storage tank 16. The positioning block 18 can be reinforced by the reinforcing rib 41 to improve the structural firmness of the positioning block 18, thereby effectively preventing the positioning block 18 from being deformed or even broken due to force.

[0054] The air ducts 27 are equidistantly distributed in an annular shape along the circumferential direction of the air blast chamber 23, and the first air outlet holes 28 are equidistantly distributed in a linear shape along the height direction of the air duct 27.

The movable block 45 can drive the heat conducting plate 46 to move along the inner wall of the fixed block 44. When each heat conducting sheet 47 is attached to the side wall of the gas storage tank 16, the heat conducting silicone grease on the end surface of the heat conducting sheet 47 can fully absorb the surface heat of the gas storage tank 16 and transfer it to the heat conducting plate 46 through the heat conducting sheet 47. Then, the heat is diffused into the surrounding air through the heat conducting plate 46, thereby further improving the cooling efficiency and effect of the gas storage tank 16.

[0057] Among them, the outer diameter of the locking cylinder 33 is equal to the inner diameter of the gas delivery port 20, the number of studs 36 and locking holes 22 is the same, the diameters are equal, and the center of each stud 36 corresponds to the center of each locking hole 22. Each stud 36 can be aligned with and pass through the corresponding locking hole 22. At this time, the nut 37 is threadedly connected to each stud 36 and tightened. The locking piece can be fixed on the gas delivery port 20 through the mutual cooperation between the stud 36, the locking hole 22, and the nut 37. At this time, the locking cylinder 33 can fit on the inner wall of the gas delivery port 20.

[0058] Among them, a layer of anti-skid pad 48 is provided on the end surface of each locking bolt 35, and the surface of the anti-skid pad 48 is engraved with a herringbone anti-skid pattern. The anti-skid pad 48 is made of rubber material and is fixed by glue or other means. When the end of the locking bolt 35 is against the wall of the air pipe 11, the anti-skid pad 48 can play a buffering and protective role to avoid excessive locking force of the locking bolt 35 and cause wear on the wall of the air pipe 11. At the same time, the anti-skid pattern on the surface of the anti-skid pad 48 can increase the friction between the locking bolt 35 and the air pipe 11 to play an anti-skid role, thereby further improving the stability of the air pipe 11 after being locked and fixed, and avoiding slipping and displacement of the air pipe 11.

The pressure and nitrogen purity in the gas tank 16 are monitored in real time by the sensor 17. When the pressure of the gas tank 16 reaches the set upper limit, the nitrogen generator stops making nitrogen and enters the standby state. The nitrogen in the gas tank 16 can be discharged through the air outlet 21 to realize the supply of nitrogen. When the temperature of the nitrogen stored in the gas tank 16 is high, the fan 26 is driven to blow air. The wind blown by the fan 26 can be introduced into the air guide cavity 30 through the air guide pipe 27, and blown out through each first air outlet 28 and the second air outlet 31.
