Single-screw type sealed refrigeration compressor

Abstract

The invention discloses a single-screw type sealed refrigeration compressor which comprises a compressor body and is characterized in that a multi-layer refrigerator is arranged above the compressor body and is provided with three layers of storage cavities from bottom to top, and the three layers of storage cavities are respectively a freezing cavity, a refrigerating cavity and a fresh-keeping cavity from bottom to top. Condensation pipes are arranged in the freezing cavity, the refrigerating cavity and the fresh-keeping cavity and are connected with the compressor body through pipelines, the number of the condensation pipes in the freezing cavity, the number of the condensation pipes in the refrigerating cavity and the number of the condensation pipes in the fresh-keeping cavity are gradually decreased, flexible air cushions are arranged at the bottoms of the freezing cavity, the refrigerating cavity and the fresh-keeping cavity, and tension films are arranged in the condensation pipes. A flexible traction wire is arranged on one side of each tension film, a gear adjuster is arranged on the compressor body, a purification tank is further arranged on one side of the compressor body, the flexible traction wires are connected with the gear adjuster, and the condensation pipes are connected with the purification tank through a pipeline. The single-screw type sealed refrigeration compressor has the characteristics of saving time and labor and being good in refrigeration effect.

Description

technical field [0001] The invention relates to the technical field of refrigerator refrigeration, in particular to a single-screw hermetic refrigeration compressor. Background technique [0002] The single-screw compressor consists of a cylindrical screw and two symmetrically arranged plane star wheels, which are installed in the casing. The screw groove, the casing (cylinder) inner wall and the star gear teeth form a closed volume. The power is transmitted to the screw shaft, and the star wheel is driven by the screw to rotate. The gas enters the screw groove from the suction chamber, and is discharged through the exhaust port and the exhaust chamber after being compressed. The role of the star wheel is equivalent to the piston of the reciprocating piston compressor. When the teeth of the star wheel move relatively in the screw groove, the closed volume gradually decreases and the gas is compressed.

AI Technical Summary

Problems solved by technology

[0003] In supermarkets or vegetable markets, the meat, milk, and vegetables sold often need to be placed in the refrigerator for freezing and preservation. The goods in the existing multi-layer refrigerators will continue to decrease during the sales process, and the salesperson needs to constantly observe and give the refrigerator Replenishment is time-consuming and labor-intensive; at the same time, when the goods are put on the shelves of multi-storey refrigerators, the goods fall into the multi-storey refrigerators and easily hit the condenser pipes, which will knock off the impurities that have remained on the inner wall of the condenser pipes for a long time, and the fallen impurities will be in the condenser pipes. Continuous circulation, when there are more and more impurities in the flow, they will circulate in the condensation pipe to the corner and easily remain here, and as more and more impurities accumulate here, it is easy to cause blockage of the condensation pipe, multi-layer refrigerator Decreased cooling effect
