Efficient drying filter

Abstract

The invention discloses an efficient drying filter. The efficient drying filter comprises a barrel, a front end cover, a rear end cover, a first filter screen, a second filter screen and drying agents, wherein the barrel, the front end cover and the rear end cover are split; the drying agents are filled in a plurality of drying agent storage boxes; the plurality of drying agent storage boxes are orderly arranged on the inner surface of the barrel and are located at a position between the first filter screen and the second filter screen; and a plurality of ventilation openings are formed in theouter surfaces of the drying agent storage boxes. According to the efficient drying filter, the drying agents are stored in the drying agent storage boxes, the drying agents with the caking phenomenon in the drying agent storage boxes can be replaced in time so as to ensure the drying efficiency, and meanwhile the cost is saved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a high-efficiency drying filter. Background technique [0002] In the refrigeration equipment, the dryer is installed between the condenser and the capillary of the refrigeration system as a filter device, which is used to dry the refrigerant flowing in the refrigeration pipeline and filter the impurities in the system. In the process of use, the two ends of the high-efficiency dry filter are usually fixedly connected by welding. If there is a blockage or damage after the fixed connection, it is difficult to replace it, and it can only be replaced as a whole, which is inconvenient to use. [0003] The Chinese patent with the prior art application number CN201621333569.0 discloses a high-efficiency dry filter, including a cylinder body, a front end cover, a rear end cover, a first filter screen, a second filter screen and a desiccant; the front end cover and the rear end co...

AI Technical Summary

Problems solved by technology

[0004] In the above technical solution, since the desiccant is accumulated between the first filter and the second filter net, agglomeration is easily generated locally during use, blocking the cylinder, and the entire desiccant needs to be replaced during replacement, which is wasteful resource
