Description

Technical Field

[0001] This utility model relates to the field of dry ice production technology, specifically a rapid cooling device for dry ice production. Background Technology

[0002] Solid carbon dioxide, commonly known as "dry ice," is widely used in various fields such as food preservation and removing grease and dirt from industrial molds and equipment as industry develops. Therefore, many manufacturers have dry ice making machines that produce dry ice blocks. Dry ice is generated by cooling carbon dioxide during production, but existing cooling devices cannot meet the needs of dry ice production.

[0003] Currently available rapid cooling devices for dry ice production do not filter the raw dry ice material before cooling, resulting in the cooled dry ice containing more impurities, which affects the quality of the dry ice and fails to meet people's needs.

[0004] Secondly, the poor mobility of the final dry ice collection structure makes it difficult to collect the finished dry ice and makes it difficult to clean the inside of the equipment later, which urgently needs to be addressed. Utility Model Content

[0005] The purpose of this invention is to provide a rapid cooling device for dry ice production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid cooling device for dry ice production, comprising a cooling box, a positioning plate, a filter screen, and an adsorption plate. A filter box is connected to the top of the cooling box. A positioning plate is provided at the top inside the filter box. The positioning plate has symmetrically connected movable slots.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This kind of rapid cooling device for dry ice production, by setting up a filter screen and an adsorption plate, can filter and adsorb impurities in carbon dioxide passing through the filter box, thereby effectively improving the quality of dry ice.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-4 An embodiment of this utility model provides a rapid cooling device for dry ice production, comprising a cooling box 1, a positioning plate 16, a filter screen 26, and an adsorption plate 27. The top of the cooling box 1 is connected to a filter box 3, and the top of the filter box 3 is provided with a positioning plate 16. The interior of the positioning plate 16 is symmetrically connected with movable grooves 23. Each of the two movable grooves 23 is connected to a limiting block 20 by a magnetic stone 24. The magnetic attraction between the magnetic iron 28 and the magnetic stone 24 can effectively improve the stability of the collection box 8 placed in the cooling box 1.

[0023] The limiting block 20 is connected to a fixed insert 25 on the side away from the magnetic stone 24. Both sides inside the filter box 3 are connected to fixed grooves 22 that match the fixed insert 25. The top of the limiting block 20 is connected to an operating block 15. The top of the movable groove 23 is connected to a limiting groove 14 that matches the operating block 15. Through the setting and cooperation of the limiting groove 14, operating block 15, limiting block 20, movable groove 23, magnetic stone 24 and fixed insert 25, the insertion state of the fixed insert 25 and the fixed groove 22 can be adjusted, which makes it easy to remove the positioning plate 16 from the top of the filter box 3 for the replacement of the filter screen 26 and the adsorption plate 27.

[0024] The bottom of the positioning plate 16 is connected to a filter screen 26 and an adsorption plate 27 respectively. The filter screen 26 and the adsorption plate 27 are set to filter and adsorb impurities in the carbon dioxide passing through the filter box 3, thereby effectively improving the quality of dry ice.

[0025] A connecting pipe 2 is connected to one side of the filter box 3, and a connecting pipe 4 is connected to the other side of the filter box 3. The other end of the connecting pipe 4 extends into the top of the cooling box 1.

[0026] The cooling chamber 1 is equipped with a condenser pipe 5. The coolant flowing in the condenser pipe 5 can cool the carbon dioxide in the cooling chamber 1. The condenser pipe 5 is designed with a wave-shaped structure to effectively extend the residence time of the coolant in the cooling chamber 1, thereby quickly cooling the carbon dioxide and improving the efficiency of dry ice production. The guide groove 7 and guide block 11 are designed so that the guide block 11 can guide and slide in the guide groove 7 to control the overall removal of the collection box 8 from the cooling chamber 1, which is convenient for collecting the dry ice in the collection box 8 and also for cleaning the inside of the collection box 8.

[0027] One end of the condenser pipe 5 extends to the outside of one side of the cooling box 1 and is equipped with a pump body 6.

[0028] The other end of the condenser tube 5 extends to the other side of the cooling box 1 and is equipped with a liquid storage tank 13, which is covered with a lid 12.

[0029] A collection box 8 is provided at the bottom of the cooling box 1. Guide blocks 11 are connected to both sides of the collection box 8. A pull handle 10 is connected to the front side of the collection box 8. A 24 is connected to the rear end of the guide block 11.

[0030] The cooling box 1 has guide grooves 7 on both sides inside, which match the guide block 11. A magnet 28 is connected to the rear end of the guide groove 7. The bottom of the cooling box 1 is connected to a base 9.

[0031] A condenser 18 is installed on the rear side of the cooling box 1. A heat exchange tube 17 and a circulation tube 19 are respectively connected to the two sides of the condenser 18. The other end of the heat exchange tube 17 is connected to the pump body 6, and the other end of the circulation tube 19 is connected to the liquid storage tank 13.

[0032] In this embodiment, carbon dioxide enters the filter box 3 through the connecting pipe 2. Impurities in the carbon dioxide are adsorbed by the filter screen 26 and the adsorption plate 27, thus removing impurities. The purified carbon dioxide then enters the cooling box 1 through the connecting pipe 4. Then, the pump 6 is started, causing the coolant in the storage tank 13 to enter the condenser pipe 5. The flowing coolant cools the carbon dioxide. The corrugated structure of the condenser pipe 5 extends the residence time of the coolant in the cooling box 1, thus better cooling the carbon dioxide. After heating, the cooled liquid enters the condenser 18 through the heat exchange pipe 17 for further cooling, and finally returns to the storage tank 13 through the circulation pipe 19 for reuse.
