Description

Technical Field

[0001] This utility model relates to the technical field of cryogenic nitrogen-generating air compressor equipment, specifically a cryogenic nitrogen-generating air compressor. Background Technology

[0002] Cryogenic nitrogen-generating air compressors are a component of nitrogen stations. During the nitrogen vulcanization process of tires, nitrogen stations are often required to supply nitrogen. When performing cryogenic nitrogen generation operations, nitrogen stations typically require cryogenic nitrogen-generating air compressors. Utility model patent application number CN202121193177.X discloses a nitrogen-generating air compressor. This compressor compresses air and delivers it through a second air guide pipe to the interiors of a first and second cooling tank for cooling. The compressed air is then delivered through the first air guide pipe to an air-water separator and a pipeline filter. The internal filtration of the device improves the purity of nitrogen. A sufficient cooling system fundamentally solves the problem of oil leakage caused by excessively long pipelines, ensuring the purity of nitrogen. According to its publicly available technical solution, existing cryogenic nitrogen air compressor equipment has two main problems during use. First, the internal components of the compressor generate a lot of heat when they move back and forth, which can accelerate the wear and tear of the equipment and reduce its service life. Second, when cooling the compressor, it cannot effectively lubricate the compactor, which is not conducive to saving energy. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cryogenic nitrogen-generating air compressor to solve the problems mentioned in the background art. This utility model can reduce working wear and improve the lubrication and cooling effect of the compressor.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cryogenic nitrogen-generating air compressor, comprising a body and a motor, wherein an inlet / outlet assembly is installed on the body, the inlet / outlet assembly comprising an inlet pipe and an outlet pipe, a compression assembly is installed on the inner side of the body, the compression assembly comprising an eccentric wheel and a piston, a collection assembly is installed at the bottom of the body, the collection assembly comprising a base box and an air duct, a pumping assembly is installed on the body, the pumping assembly comprising a pump casing and an impeller, a spraying assembly is installed on the pump casing, the spraying assembly comprising a suction pipe and a nozzle, and a cooling assembly is installed on the body, the cooling assembly comprising an inlet and an outlet.

[0005] Furthermore, both the inlet and outlet pipes are installed on one side of the machine body, the motor is bolted to the top of the machine body, the eccentric wheel is mounted on the inner side of the machine body via a bearing, and the top of the eccentric wheel passes through the inner wall of the machine body via a sealing ring and is keyed to the output shaft of the motor.

[0006] Furthermore, a connecting rod is installed on the inner side of the machine body, the outer side of the piston is clamped on the inner wall of the machine body, the two ends of the connecting rod are connected to the eccentric wheel and the piston respectively through bearings, and a one-way valve is installed on the inner side of both the inlet pipe and the outlet pipe.

[0007] Furthermore, the inlet is located on the other side of the machine body, and the outlet is located at the bottom of the machine body. A one-way valve is installed on the inner side of both the inlet and the outlet. A filter cartridge is installed on the other side of the machine body by bolts, and the filter cartridge is sleeved on the outside of the inlet.

[0008] Furthermore, the base box is bolted to the bottom of the machine body, the air duct is welded to the top of the base box, and a nylon mesh is glued to the inside of the air duct, with the nylon mesh evenly distributed on the inside of the air duct.

[0009] Furthermore, the pump housing is bolted to the bottom of the machine body, a turntable is installed on the inner side of the machine body, the top of the turntable is welded to the bottom of the eccentric wheel, and the bottom of the turntable is mounted to the bottom of the machine body via bearings.

[0010] Furthermore, the impeller is installed inside the pump casing, and the top of the impeller passes through the bottom of the machine body through a sealing ring and is keyed to the center of the turntable. The suction pipe is welded to the bottom of the pump casing, and the rotating rod is installed at the bottom of the base box. The top of the rotating rod passes through the suction pipe and is welded to the bottom of the impeller.

[0011] Furthermore, the nozzle is installed inside the machine body, and a spray pipe is welded to the bottom of the nozzle. The bottom end of the spray pipe passes through the bottom of the machine body and is welded to the outer side of the pump housing. The nozzle is connected to the pump housing through the spray pipe.

[0012] Beneficial effects: 1. When this cryogenic nitrogen-generating air compressor is in use, the motor drives the connecting rod through the eccentric wheel, which in turn drives the piston to move back and forth inside the machine body. Air is drawn in through the inlet pipe, and then compressed inside the machine body and sent out through the outlet pipe, thus realizing the air compression operation. When the piston moves back and forth, the air is filtered by the filter cartridge and enters the left side of the machine body through the inlet, and then flows down to the inside of the bottom box through the outlet. The reciprocating motion of the piston automatically performs heat dissipation, which not only reduces the operating temperature of the equipment and reduces wear, but also saves the energy required for heat dissipation.

[0013] 2. When using this cryogenic nitrogen-generating air compressor, an oil-water mixture is injected into the bottom chamber. The eccentric wheel drives the impeller to rotate via the turntable, and the rotating rod thoroughly mixes the mixture. The mixture is then drawn into the pump casing through the suction pipe, transported by the impeller to the nozzle, and sprayed into the machine body through the nozzle. The mixture provides lubrication and cooling for the components inside the machine. After the mixture enters the bottom chamber downwards through the outlet, it falls to the bottom of the bottom chamber. As the mixture is carried upwards by the airflow in the air duct, it is absorbed by the nylon mesh and drips back into the bottom chamber for recycling and reuse, reducing resource waste. This also improves the lubrication and cooling effect of the compressor, ensuring its service life.

On the inner wall of the machine body 1, the two ends of the connecting rod 7 are connected to the eccentric wheel 5 and the piston 6 respectively via bearings.

The inlet 10 is located on the other side of the machine body 1, and the outlet 12 is located at the bottom of the machine body 1. One-way valves are installed on the inner sides of both the inlet 10 and the outlet 12. A filter cartridge 11 is bolted to the other side of the machine body 1, and the filter cartridge 11 is fitted over the outside of the inlet 10. In use, the motor 2 drives the connecting rod 7 via the eccentric wheel 5, causing the connecting rod 7 to... The piston 6 moves back and forth inside the body 1, drawing air in through the inlet pipe 3 and then compressing the air inside the body 1 before sending it out through the outlet pipe 4, thus achieving air compression. As the piston 6 moves back and forth, the air is filtered by the filter cartridge 11 and enters the left side of the body 1 through the inlet 10, then flows downward through the outlet 12 to the inside of the bottom box 9. The reciprocating motion of the piston 6 automatically dissipates heat, reducing the operating temperature of the equipment, reducing wear and tear, and saving energy required for heat dissipation.

[0021] In this embodiment, the base box 9 is bolted to the bottom of the machine body 1. The air duct 18 is welded to the top of the base box 9.

As piston 6 moves back and forth, air is filtered by filter cartridge 11 and enters the left side of compressor body 1 through inlet 10, then flows downwards through outlet 12 to the inside of bottom chamber 9. The reciprocating motion of piston 6 automatically dissipates heat, reducing equipment operating temperature, minimizing wear, and saving energy. An oil-water mixture is injected into bottom chamber 9. The eccentric wheel 5 drives the impeller 14 to rotate via the turntable 8. The rotating rod 16 thoroughly mixes the liquid. The liquid in the bottom box 9 is sucked into the pump casing 13 through the suction pipe 15, and then transported to the nozzle by the impeller 14. It is then sprayed into the machine body 1 through the nozzle 17. The liquid provides lubrication and cooling for the components in the machine body 1.
