Multi-station crystallization cylinder barrel of dry ice machine

Abstract

The invention discloses a multi-station crystallization cylinder barrel of a dry ice machine, and the multi-station crystallization cylinder barrel comprises two parallel side plates and four mutuallyparallel clapboards which are vertically connected between the two side plates. A carriage plate perpendicular to the four clapboards is horizontally connected at the bottoms of the four clapboards,and a top plate is horizontally arranged at the tops of the four clapboards. The top plate, the carriage plate and every two adjacent clapboards form a cylinder chamber. The middle parts of the two side plates are respectively provided with a piston inlet and a dry ice outlet. The carriage plate is connected to a transmission device and can drive the four clapboards to slide synchronously along the side plates and the top plate. The top plate is provided with a plurality of liquid carbon dioxide input ports and a plurality of gaseous carbon dioxide output ports; a dry ice mold with a screen mold is arranged at the dry ice outlet; According to the method, when the piston extrudes dry ice in one of a plurality of cylinders, the other cylinders can be filled with liquid carbon dioxide and crystallized, thus greatly saving the waiting time required for crystallization.

Description

technical field

[0001] The invention relates to a crystallization cylinder, in particular to a multi-station crystallization cylinder of a dry ice machine for producing dry ice. Background technique

[0002] The crystallization cylinder of the traditional dry ice machine is connected to the hydraulic cylinder, and liquid carbon dioxide is injected into the crystallization cylinder to form gaseous carbon dioxide during the crystallization process. After the gaseous carbon dioxide is fully released, the piston connected to the hydraulic cylinder feeds the crystallization cylinder, and the dry ice powder is squeezed through the dry ice at the end. Mold forming output.

[0003] In the traditional structure, crystallization and extrusion are in the same cylinder chamber, and the beats are arranged linearly. The specific process steps are:

[0004] 1. When the piston returns to the zero position, start filling to inject liquid carbon dioxide, the beat is about 6-10 seconds; [0...
