Description

Technical Field

[0001] The utility model relates to storage equipment, in particular to a cold storage air purification system. Background Art

[0002] Cold storage is a device that uses artificial means to create a low-temperature environment to store temperature-sensitive items such as food, medicine, and vaccines to extend the shelf life of the items. When storing items, long-term use of cold storage is prone to breeding bacteria, especially when storing fresh products, it will also produce harmful gases such as ethylene, carbon dioxide, and hydrogen sulfide, affecting storage effects and safety.

[0003] For this reason, the cold storage needs to purify the internal air when in use. There are two main existing purification methods: one is to drive the air in the cold storage to circulate internally so that it passes through the filter component or the adsorption component. The disadvantage of this method is that the filter component or the adsorption component needs to be replaced frequently, which is cumbersome and cannot remove harmful gases; the other is to use external air to replace the internal air. This method has a good purification effect, but it needs to be cooled again after ventilation, which consumes more energy.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The utility model aims to provide a cold storage air purification system with scientific design, good purification effect, relatively low energy consumption and strong practicality in view of the deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a cold storage air purification system, including a cold storage inner wall, a cold air channel interlayer coated on the outside of the cold storage inner wall, an air intake channel interlayer arranged on the outside of the cold air channel interlayer, an outer thermal insulation layer coated on the outside of the air intake channel interlayer and an exhaust fan; the cold air channel interlayer is provided with an exhaust pipe extending out of the outer thermal insulation layer and an exhaust port penetrating the inner wall of the cold storage, the exhaust pipe is connected to the exhaust port of the exhaust fan, and the air intake channel interlayer is provided with an exhaust pipe extending out of the outer thermal insulation layer and an exhaust pipe penetrating the inner wall of the cold storage.

[0007] Based on the above, the cold air channel interlayer is separated from the air intake channel interlayer by a copper plate.

[0008] Based on the above, the air extraction pipe and the air intake pipe are both located at the top center of the outer thermal insulation layer, and the air intake pipe is arranged around the outside of the air extraction pipe.

[0009] Based on the above, the air inlet channel interlayer is covered on the outside of the top wall and side wall of the cold air channel interlayer, the air exhaust port is located at the center of the bottom wall of the inner wall of the cold storage, and the air outlet pipe includes several side vertical pipes for air outlet at the top end, and several of the side vertical pipes are evenly arranged around the bottom of the side walls of the inner wall of the cold storage.

[0010] Based on the above, an air outlet one-way valve is provided on the air extraction port to prevent the gas in the cold air channel interlayer from flowing back; an air inlet one-way valve is provided on each of the side vertical pipes to prevent the gas in the inner wall of the cold storage from flowing back.

[0011] The utility model has substantial characteristics and progress compared with the prior art. Specifically, when the exhaust fan is used to exhaust air, the cold air in the cold storage enters the cold air channel interlayer through the exhaust port, and is finally discharged from the exhaust pipe. At the same time, negative pressure is generated in the cold storage, and external fresh air enters the air inlet channel interlayer from the air inlet pipe, and finally enters the cold storage from the air outlet pipe. Fresh air is used to replace the cold air in the cold storage. The contact area between the cold air channel interlayer and the air inlet channel interlayer is large, and the cold air and the fresh air exchange heat when entering and exiting, thereby reducing the temperature of the fresh air and further reducing energy consumption. The utility model has the advantages of scientific design, good purification effect, relatively low energy consumption and strong practicality.

[0012] Furthermore, the copper plate has a high thermal conductivity, which is more conducive to the heat exchange between cold air and fresh air; the air inlet pipe is arranged around the outside of the exhaust pipe, so that the air starts to exchange heat with the exhausted cold air when entering, further improving the heat exchange effect; the air exhaust port is arranged at the center of the bottom wall of the inner wall of the cold storage, and the cold air is discharged from the center. A number of vertical pipes are arranged around the inner wall of the cold storage, and fresh air enters from the edge, so that the air in the cold storage flows in an orderly manner and the air replacement is more sufficient.

[0018] The cold air channel interlayer 2 is provided with an exhaust pipe 6 extending out of the outer insulation layer 4 and an exhaust port 7 penetrating the inner wall 1 of the cold storage. The exhaust pipe 6 is connected to the exhaust port of the exhaust fan 4. The air inlet channel interlayer 3 is provided with an air inlet pipe 8 extending out of the outer insulation layer 4 and an air outlet pipe penetrating the inner wall of the cold storage. When the exhaust fan 5 draws air, the cold air in the cold storage enters the cold air channel interlayer 2 through the exhaust port 7 and is finally discharged from the exhaust pipe 6. At the same time, negative pressure is generated in the cold storage, and external fresh air enters the air inlet channel interlayer 3 from the intake pipe 8 and finally enters the cold storage from the outlet pipe. The exhaust pipe 6 and the intake pipe 8 are both located at the top center of the outer insulation layer 4. The intake pipe 8 is arranged around the outside of the exhaust pipe 6, so that the air starts to exchange heat with the discharged cold air when entering. The cold air channel interlayer 2 is separated from the air intake channel interlayer 3 by a copper plate 12. The contact area between the cold air channel interlayer 2 and the air intake channel interlayer 3 is large, and the copper plate 12 has high thermal conductivity, so that cold air and fresh air exchange heat when entering and exiting.

[0019] The air extraction port 7 is located at the center of the bottom wall of the cold storage inner wall 1, and the air outlet pipe includes a plurality of vertical pipes 9 with air outlet at the top, and the plurality of vertical pipes 9 are evenly arranged around the bottom of the side walls of the cold storage inner wall 1; in this way, the cold air can be discharged from the center and the fresh air can enter from the edge, so that the air in the cold storage can flow in an orderly manner and the air replacement can be more sufficient. The air extraction port 7 is provided with an air outlet check valve 10 to prevent the gas in the cold air channel interlayer 2 from flowing back; each vertical pipe 9 is provided with an air inlet check valve 11 to prevent the gas in the cold storage inner wall 1 from flowing back.

[0020] Working principle:

[0021] Start the exhaust fan 5 to exhaust air, and the cold air in the cold storage enters the cold air channel interlayer 2 through the exhaust port 7, and is finally discharged from the exhaust pipe 6. At the same time, negative pressure is generated in the cold storage, and external fresh air enters the air inlet channel interlayer 3 from the air inlet pipe 8, and finally enters the cold storage from the air outlet pipe. Fresh air is used to replace the cold air in the cold storage, and the gas purification effect is good. The contact area between the cold air channel interlayer 2 and the air inlet channel interlayer 3 is large, and the cold air and the fresh air exchange heat when entering and exiting, thereby reducing the temperature of the fresh air and further reducing energy consumption.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
