A universal filter for refrigeration equipment

Abstract

The invention discloses a general-purpose filter for refrigeration equipment, which comprises a cylinder body and a front end cover and a rear end cover installed at both ends of the cylinder body. The end cover is connected with the barrel; the first metal mesh is installed inside the barrel close to the front end cover, and the second metal mesh is arranged at the other end of the first metal mesh; the first metal mesh and the second metal mesh inside the barrel A desiccant is arranged between the metal meshes; an inlet is arranged on the outside of the cylinder close to the front end cover, and an outlet is arranged on the other end opposite to the inlet. The invention is simple in structure and reasonable in design; the device changes the connection and fixing mode of the filter through the first connection mechanism and the second connection mechanism, avoids clogging or damage and difficult replacement, and improves the convenience of use of the filter; A heating device is added to the mechanism, which is beneficial to deal with the ice blockage at the joint of the filter, thereby prolonging the service life of the filter, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a general-purpose filter for refrigeration equipment. Background technique [0002] The refrigerator dry filter is a very important part in the whole refrigeration system, its main function is to filter out the moisture in the refrigeration system and the impurities that may cause pipeline blockage. However, in many refrigeration systems, the installation methods are different, and there seems to be no rules to follow. In fact, there are reasonable installation methods, that is, the inlet of the filter should be at the bottom and the outlet should be upward; the dry filter mainly plays the role of filtering impurities. ; Generally speaking, it depends on the refrigeration system of the refrigerator and air conditioner to determine the specifications of the dryer, such as diameter, inner diameter, outer diameter specifications, and internal parts, such as filter bowls, mesh cloth,...

AI Technical Summary

Problems solved by technology

[0003] However, at present, during the use of refrigeration equipment, when installing the dry filter, it is usually fixed by welding. If it is blocked or damaged after the fixed connection, it is difficult to replace it, and it can only be replaced as a whole, which is inconvenient to use. At the same time, ice blockage often occurs at the joint of the filter, causing the refrigeration equipment to malfunction and cannot be used normally. When necessary, the joint is heated with a welding torch. The maintenance process is cumbersome and inconvenient to use.
