Problems solved by technology
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. When the temperature of the hydraulic oil exceeds 70 degrees, it is easy to deteriorate and dilute, especially in 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 the hydraulic oil pipeline is easily deformed, which easily causes oil leakage from the pipeline; on the other hand, the piston in the hydraulic cylinder is easy to wear, which affects the equipment. service life

The invention discloses an oil cylinder cooling device for a dry ice machine. The oil cylinder cooling device comprises a liquid CO2 storage cylinder, an oil tank, a liquid CO2 pipeline, a hollow square liquid CO2 pipeline, a pipeline connector, a pipeline valve I and a pipeline valve II. The oil tank is connected with an oil pump, and the liquid CO2 pipeline is communicated with the liquid CO2 storage cylinder. The hollow square liquid CO2 pipeline is arranged in the oil tank, one end of the hollow square liquid CO2 pipeline penetrates the side wall of the oil tank and then passes through the pipeline valve I and the pipeline connector sequentially to be communicated with the liquid CO2 pipeline which is communicated with the liquid CO2 storage cylinder, and the other end of the hollow square liquid CO2 pipeline penetrates the side wall of the oil tank and then passes through the pipeline valve II to be connected with a pipeline entering a dry ice extrusion forming cavity. By means of the technical scheme, the oil cylinder cooling device for the dry ice machine has the advantages that structural simplicity, convenience and reliability are realized, oil in the oil tank is effectively cooled, the problem of oil leakage of the pipelines is solved, and the service life of equipment is prolonged.
Description
technical field [0001] The invention belongs to equipment for producing dry ice, in particular to a cooling device for an oil cylinder of a dry ice 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 chamber and is extruded by a hydraulic cylinder. 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. When the temperature of the hydraulic oil exceeds 70 degrees, it is easy to deteriorate and dilute, especially in 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 the hydraulic oil pipeline is easily deformed, which easily causes oil leakage from the pipeline; on ...
