Solid carbon dioxide former and control method thereof

Abstract

The invention provides a solid carbon dioxide former and a control method thereof,and further relates to the technical field of production of solid carbon dioxide. The solid carbon dioxide former comprises a squeeze-type cavity,a compression component,a material storage tower and a die head component. The compression component comprises a first power device,a piston connection rod and a piston,wherein the first power device,the piston connection rod and the piston are connected in sequence; the piston is arranged in the squeeze-type cavity,and the first power device drives the piston connection rod to move back and forth in the horizontal direction to drive the piston to move back and forth in the squeeze-type cavity so that granular solid carbon dioxide can be squeezed into blocky solid carbon dioxide. The material storage tower is vertically arranged above the squeeze-type cavity and communicated with the squeeze-type cavity,and is used for adding the snowflake-shaped carbon dioxideto the squeeze-type cavity. The material storage tower is adopted for feeding,and the process is omitted that physical changes of liquid carbon dioxide occur in a cavity and the liquid carbon dioxideis changed into the snowflake-shaped carbon dioxide,so that working time is saved,and the squeeze working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of solid carbon dioxide production, in particular to a solid carbon dioxide molding machine and its control method. Background technique [0002] At present, the production method of solid carbon dioxide is usually to physically change the liquid carbon dioxide in the cavity to form a snowflake shape, then extrude the snowflake-shaped carbon dioxide through an extrusion mechanism, and finally push the snowflake-shaped carbon dioxide out of the front die assembly. [0003] The applicant in this case previously designed and developed a solid carbon dioxide manufacturing machine extrusion molding device (CN206538202U). Although this molding machine has improved the sealing and stability of the extrusion chamber, it still passes the liquid carbon dioxide through the throttling expansion valve first. After entering the material opening, physical changes occur in the extrusion cavity to form powdery solid carbon d...
