The invention discloses a dry ice former, controlled via a PLC (programmable logic controller) and comprising a liquid CO2 storage tank, an oil tank connected with an oil pump, a liquid CO2 pipeline communicated with the liquid CO2 storage tank, a hydraulic cylinder and a dry ice forming assembly. An oil tank cooler is disposed inside the oil tank, a pipeline distributor is disposed on the liquid CO2 pipeline between the oil tank and the dry ice forming assembly. The dry ice forming assembly comprises a mold barrel fixedly connected with the hydraulic cylinder, a mold barrel piston, a mold head and a mold base, and a bore locking ring is mounted in a screw hole in the center of the mold barrel piston. The dry ice former is simple in structure and handy and reliable, the temperature of oil in the oil tank is effectively reduced, the service life of the former is prolonged, the problem of mold head damage due to screw failure is solved, normal production of the former is ensured, and the cost is reduced.
Description
technical field [0001] The invention belongs to equipment for manufacturing dry ice, in particular to a dry ice forming machine. Background technique [0002] Currently in the dry ice manufacturing process, liquid CO 2 from liquid CO 2 storage tank into liquid CO 2 The pipeline enters the dry ice extrusion molding cavity, and the hydraulic cylinder pushes the piston of the mold cylinder to extrude, and the dry ice is extruded from the die head to form. The hydraulic oil in the oil tank is pumped into the hydraulic cylinder by the oil pump through the oil circuit to work. Since the hydraulic cylinder works for a long time, it is easy to cause the temperature of the hydraulic oil to be high. If the oil temperature exceeds 70 degrees, it is easy to cause deterioration and dilution, especially when the temperature is relatively high. In the case of high temperature, the hydraulic oil in the oil tank is in a high temperature state for a long time. On the one hand, the seal of ...
