Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a dry ice feeding device. Background Art

[0002] Dry ice is solid carbon dioxide. The difference between dry ice and ordinary ice lies in its sublimation properties. Ordinary ice turns into liquid water when it melts, while dry ice sublimates directly from solid to gas without leaving any liquid. This property makes dry ice very useful in situations where rapid cooling is required but no liquid is desired, such as food preservation and stage effects. Dry ice after production generally comes in granular and block forms. The factory will first produce granular dry ice and store it during production. When block dry ice needs to be prepared, some of the stored granular dry ice is removed and transported to a dry ice briquetting machine to produce block dry ice.

[0003] For example, an adjustable screw feeder disclosed in the authorization announcement number CN209438407U includes a stirring and mixing device and an adjustable feeding device arranged on the left side of the stirring and mixing device, a height adjustment device is installed at the bottom of the adjustable feeding device, the adjustable feeding device includes a feeding box and a first drive motor installed at the left end of the feeding box, the height adjustment device includes a bottom support seat and a second drive motor, a first reducer, a first nut block and a second nut block respectively arranged on the top of the bottom support seat, a threaded rod body is connected to the output shaft of the first reducer, the top of the first nut block is hinged with a left hinge plate, and the top of the second nut block is hinged with a right hinge;

[0004] Although it can not only save more labor costs and greatly improve production efficiency compared to manual loading, the stirring chain can also separate the plastic particles adhering to the inner wall of the color mixing box during operation, so that the color mixing is more uniform and the product quality is better. However, it does not solve the problem that the existing loading device is not conducive to convenient spiral transportation of dry ice particles when in use, is not convenient for angle-adjustable loading and circular rotation loading, and is not convenient for multi-position and multi-channel loading, which greatly affects the loading range and the loading efficiency of the loading device.
