Description

Technical Field

[0001] The utility model relates to the technical field of dry ice machines, in particular to a dry ice machine with a high ice yield rate. Background Art

[0002] A dry ice machine is a device that uses liquid carbon dioxide to convert into a solid refrigerant, namely dry ice particles, through a specific process. This device is widely used in many fields, including medicine, food, aerospace, scientific research, etc. It is also often used in special effects stage performances, photography and videography, etc. The working principle of a dry ice machine mainly involves compressing high-pressure liquid carbon dioxide through a compressor, and then reducing the pressure through an expansion valve to liquefy the carbon dioxide. Then, the liquid carbon dioxide evaporates into a gas through a heating rod, and forms ice mist on the heating rod. Finally, the ice mist is compressed into dry ice particles. During the dry ice production process, dry ice will adhere to the inner wall and need to be scraped off. In order to better scrape off the dry ice adhered to the inner wall, a dry ice machine with a high ice yield is proposed.

[0003] For example, a dry ice machine disclosed in the authorization announcement number CN213997066U includes a feeding device and a feeding device. The feeding device includes a hopper and a feeding trough. A cutter disc is installed on one side of the hopper. A turntable is also provided in the hopper. The turntable is connected to the cutter disc via a connecting rod. The feeding device includes a feeding roller. The feeding roller is connected to the turntable via a transmission assembly. When working, the feeding roller drives the turntable and the cutter disc to rotate through the transmission assembly, cutting the dry ice blocks on the feeding trough so that the dry ice fragments enter the hopper. At the same time, the connecting rod stirs the hopper so that the dry ice falls into the feeding device. After being transported by the feeding roller, the dry ice is ejected from the feeding device.

[0004] Although the dry ice machine has a feeding trough installed on one side of the silo, the feed box transports dry ice pellets while driving the blade to cut the dry ice blocks in the feeding trough, realizing the function of automatic feeding through dry ice blocks, the dry ice machine can also directly feed dry ice pellets. It can adopt two different feeding methods according to different needs and is suitable for cleaning different object surfaces;
