Automatic dry ice making machine

Dry ice production uses liquid carbon dioxide as raw material, expands through throttling, and compresses and extrudes the oil cylinder. The dry ice pellet machine relates to a machine for manufacturing dry ice (that is, solid carbon dioxide).

The existing equipment for manufacturing dry ice includes an expansion tower capable of supplying liquid carbon dioxide to expand into snowflake-like carbon dioxide and a compressor for compressing snowflake-like carbon dioxide into dry ice. The disadvantages are 1) The puffing tower and the compressor are independent, so it is difficult to achieve automatic and continuous production of dry ice due to the dispersed structure, so the production efficiency is relatively low, and the work is unstable and reliable. 2) Because of the dispersed structure and the puffing tower is relatively large, Therefore, the space required for equipment installation and use is large, and the total investment and production cost of the equipment is high, which results in the dry ice being expensive and not easily accepted by people.

The purpose of the dry ice pellet machine is to overcome the shortcomings in the prior art mentioned above and provide a dry ice machine that can automatically and continuously produce dry ice, and make it have high production efficiency, reliable work, compact structure, small volume, etc. Features.

Dry ice pellet machine The dry ice machine includes a compression box installed on the fuselage, an exhaust box installed on the top of the compression box and separated by a gas filter, a sealed door installed on one side of the compression box, and installed in the compression box. A piston, a feeding pipe with a solenoid valve installed on the compression box, and a left piston rod and a right piston rod that can drive the sealing door and the piston to make a set motion respectively.

The left and right piston rods in the dry ice pellet machine can be connected with hydraulic components with electric control. This component includes an auxiliary oil cylinder set in the fuselage that enables the left piston rod to reciprocate and the right piston rod to function A reciprocating main oil cylinder, and a set of hydraulic components including a fuel tank, an oil filter, a high-pressure oil pump, a directional valve, a proportional relief valve, a proportional pressure reducing valve, and an electric control element including a probe and a sensor.
