shuliy - Model SL -Automated dry ice making machine

The dry ice is made by using liquid carbon dioxide as raw material, by throttling expansion, and the cylinder is compression-molded. The utility model relates to a machine for manufacturing dry ice (that is, solid carbon dioxide).

An existing apparatus for manufacturing dry ice comprising a puffing tower capable of supplying liquid carbon dioxide into a snow-like carbon dioxide and a compressor for compressing snow-like carbon dioxide into dry ice, the disadvantage of which is 1) The puffing tower and the compressor are independent bodies, so it is difficult to realize automatic and continuous production of dry ice due to structural dispersion, so the production efficiency is relatively low, the work is unstable and reliable; 2) due to the structural dispersion and the puffing tower is relatively tall, Therefore, the space required for installation and use of the equipment is large, the total investment of the equipment and the production cost are high, which causes the price of dry ice to be expensive and is not easily accepted by people.

The purpose of the utility model is to overcome the shortcomings of the prior art mentioned above and to provide a dry ice machine capable of automatically and continuously producing dry ice, and has the advantages of high production efficiency, reliable operation, compact structure, small volume, etc. Features.

The dry ice machine of the present invention comprises a compression box mounted on the fuselage, an exhaust box installed at the top of the compression box and separated by a gas filter, a sealing door installed at one side of the compression box, and installed in the compression box The piston, the feeding tube with the solenoid valve installed on the compression box, and the left piston rod and the right piston rod which can respectively drive the sealing door and the piston to set movement.

The left and right piston rods in the dry ice pellet machine of the utility model can be connected with the hydraulic component with electric control, and the assembly comprises an auxiliary oil cylinder disposed in the fuselage for reciprocating the left piston rod, and the right piston rod can be A reciprocating master cylinder, and a set of hydraulic components including a fuel tank, an oil filter, a high pressure oil pump, a reversing valve, a proportional relief valve, a proportional pressure reducing valve, and an electronic control unit including the probe and the sensor.

The exhaust box in the dry ice pellet machine of the present invention may be provided with an exhaust pipe to direct carbon dioxide gas to the outside to directly discharge the atmosphere or recover. When using the dry ice machine of the present invention to produce dry ice, the auxiliary piston-cylinder drives the left piston rod to push the sealing door to move in the direction of the compression box until the compression box is closed; then the electromagnetic feed valve is opened, and the liquid carbon dioxide is fed from the feed. The tube enters the compression box, and expands into a snow-like carbon dioxide in the box and simultaneously generates carbon dioxide gas, wherein the gaseous carbon dioxide escapes through the gas filter at the top of the compression box, and the snow-like carbon dioxide remains in the compression box, and the main cylinder drives the right piston. The rod drive piston moves to the left to press the snow-like carbon dioxide into dry ice; after the dry ice is formed, the auxiliary cylinder drives the left piston rod to retreat and the compression box door is opened, and the dry ice at this time is pushed out of the compression box by the piston that continues to move leftward. Out of the machine; finally, the right piston rod is driven by the main cylinder to reset the piston. At this point, the dry ice machine completed a work cycle for producing dry ice, and then repeated the next work cycle; the dry ice machine of the present invention continuously produced dry ice continuously.
