Description

Technical Field

[0001] This utility model belongs to the field of production technology. Specifically, this utility model relates to a compressed air cooling structure. Background Technology

[0002] Compressed air and nitrogen are both commonly used gases in production. Currently, compressed air is produced by screw air compressors. Compressed air contains a small amount of moisture. If this moisture is not removed in time, it will damage various gas components and electronic components used subsequently, causing solenoid valves to malfunction or pneumatic valves to jam. Using gas dryers is costly and space-consuming. Nitrogen is produced by vaporizing liquid nitrogen into nitrogen gas before it can be used normally. Because the vaporization of liquid nitrogen requires a large amount of heat absorption, a thick layer of ice will form on the outer surface of the nitrogen pipeline, affecting the vaporization effect of liquid nitrogen. The pipeline also needs to be manually de-iced before it can be used normally, which seriously affects production efficiency.

[0003] Utility model patent CN205269362U, published on June 1, 2016, discloses an energy-saving compressed air dehumidification and cooling device. This device includes an air compressor, an air storage tank, a cooler, a heater, an intermediate circulation tank, and a circulation pump. Compressed air output from the air compressor is sent to the air storage tank. The air storage tank then sends the compressed air through an air delivery pipeline to the cooler for cooling, and finally to the heater for heating. The heater outputs the compressed air through an air output pipeline. However, this energy-saving compressed air dehumidification and cooling device does not solve the aforementioned technical problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a compressed air cooling structure that achieves water-air separation in compressed air, prevents damage to components in the workshop, and improves the efficiency of liquid nitrogen vaporization.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The compressed air cooling structure includes a screw air compressor and a liquid nitrogen storage tank. The screw air compressor is connected to a compressed air pipeline, the liquid nitrogen storage tank is connected to a nitrogen pipeline, the nitrogen pipeline is connected to a vaporizer, and the vaporizer includes a heat-absorbing rod.

[0007] The compressed air pipeline is connected to an air storage tank, and the bottom of the air storage tank is equipped with a drain valve. Both the air storage tank and the vaporizer are connected to workshop pipelines.

[0008] The heat-absorbing rod is provided with a support frame on the outside, the support frame is arranged in layers, and the heat-absorbing rod is arranged at equal intervals.

[0009] The vaporizer has a support at its bottom, and the compressed air pipe passes through the support.

[0010] The outer end of the support frame is provided with a clamp, and the compressed air pipe passes through the clamp.

[0011] Both the nitrogen pipeline and the compressed air pipeline are equipped with valves.

[0012] The heat-absorbing rod is a cylindrical structure and is vertically arranged.

[0013] The technical advantages of this invention are as follows: The compressed air cooling structure, through its rational arrangement of compressed air pipelines and the use of a vaporizer, achieves water vapor separation in the compressed air via heat exchange between compressed air and liquid nitrogen. This prevents damage to components within the workshop, ensures continuous and normal equipment operation, and provides a heat source for liquid nitrogen, improving its vaporization effect. It also reduces the workload of manual de-icing for production personnel, lowering labor intensity. The compressed air and nitrogen pipelines operate independently, without interfering with each other, thus preventing production abnormalities. Compared to existing technologies, it also eliminates the need for a gas dryer, reducing the cost and spatial arrangement complexity of gas dryer applications. Attached Figure Description

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0018] like Figure 1As shown, the compressed air cooling structure includes a screw air compressor 1 and a liquid nitrogen storage tank 2. The screw air compressor 1 is connected to a compressed air pipeline 3, and the liquid nitrogen storage tank 2 is connected to a nitrogen pipeline 4. The nitrogen pipeline 4 is connected to a vaporizer 8, which includes a heat-absorbing rod 9. The compressed air is cooled by the heat absorption of the vaporizer 8. The moisture contained in the compressed air is cooled into liquid water and introduced into the air storage tank 5 along with the compressed air. The compressed air pipeline 3 also serves as a heat absorption area for the liquid nitrogen, reducing the adhesion rate of ice on the vaporizer 8 and the heat-absorbing rod 9, extending the manual de-icing cycle, reducing the workload of workers, and making nitrogen generation faster to meet the needs of continuous production.

[0019] like Figure 1 As shown, compressed air pipeline 3 is connected to air storage tank 5, and air storage tank 5 is equipped with a drain valve 6 at the bottom. Air storage tank 5 is connected to workshop pipeline 7. Air storage tank 5 is used to store cooled compressed air. The drain valve 6 at the bottom of the tank can drain liquid water, realizing gas-water separation. After the compressed air is introduced into the workshop, the gas components and electronic components used in the workshop will not have their lifespan affected by the moisture content in the gas.

[0020] like Figure 1 As shown, a support frame 11 is provided on the outside of the heat absorption rod 9. The support frame 11 is arranged in layers, and the heat absorption rods 9 are arranged at equal intervals. Multiple support frames 11 restrict the position of the heat absorption rods 9, which facilitates the matrix arrangement of the heat absorption rods 9, further improves the heat absorption effect, and improves the stability of the heat absorption rods 9, meeting the requirements for long-term use of the vaporizer 8.

[0021] like Figure 1 As shown, a support 10 is provided at the bottom of the vaporizer 8, and the compressed air pipe 3 passes through the support 10. Passing the compressed air pipe 3 through and erecting it on the support 10 is beneficial for its overhead installation, reducing the probability of damage. In situations where site space is difficult to arrange, simply placing the compressed air pipe 3 directly under the vaporizer 8 can reduce the spatial impact on surrounding equipment, simplify the layout process, reduce the difficulty of equipment installation, and at the same time reduce the adverse factors of later pipeline inspection and maintenance.

[0022] like Figure 1As shown, a clamp 12 is provided at the outer end of the support frame 11, through which the compressed air pipe 3 passes. The dashed line in the figure shows the schematic arrangement path of the compressed air pipe 3 passing through the clamp 12. The clamp 12 on the outer side of the support frame 11 does not affect the normal operation of the heat absorber rod 9. The compressed air pipe 3 is arranged along the outer side of the heat absorber rod 9 and fixed with the clamp 12. The height of the compressed air pipe 3 and the heat absorber rod 9 are matched, achieving sufficient heat exchange between the compressed air and liquid nitrogen, further improving the liquid nitrogen vaporization effect and reducing the moisture content of the compressed air. In cases with multiple vaporizers 8, the arrangement of the compressed air pipe 3 is highly flexible. A combination of passing through the bracket 10 and fixing with the clamp 12 can be used to reduce the difficulty of spatial arrangement and the impact on surrounding equipment.

[0023] like Figure 1 As shown, valves 13 are installed on nitrogen pipeline 4, compressed air pipeline 3, and workshop pipeline 7. Multiple valves 13 are installed. The valves 13 on compressed air pipeline 3 and workshop pipeline 7 meet the opening and closing requirements of nitrogen pipeline 4 and compressed air pipeline 3, and also facilitate periodic maintenance of screw air compressor 1 and liquid nitrogen storage tank 2. The valves 13 on workshop pipeline 7 allow production personnel to conveniently use gas within the workshop.

[0024] like Figure 1 As shown, the heat-absorbing rod 9 has a cylindrical structure and is vertically arranged. This structure expands the heat absorption range of the heat-absorbing rod 9, improves the liquid nitrogen vaporization effect, and increases the nitrogen generation rate.

[0025] This compressed air cooling structure, through the rational arrangement of compressed air pipelines and the use of vaporizer 8, achieves water vapor separation in compressed air through heat exchange between compressed air and liquid nitrogen. This avoids damage to components in the workshop, ensures the continuous normal operation of the equipment, and provides a heat source for liquid nitrogen, improving the vaporization effect of liquid nitrogen, reducing the workload of manual de-icing by production personnel, and lowering labor intensity. The compressed air pipeline and nitrogen pipeline operate independently without affecting each other, avoiding production abnormalities. Compared with existing technologies, it also eliminates the need for a gas dryer, reducing the cost of applying a gas dryer and the difficulty of its spatial arrangement.

[0026] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
