Abstract

The invention relates to a dry filter. The dry filter comprises a barrel body, a front end cover, a rear end cover, filter screens and a drying agent, wherein the front end cover and the rear end cover are arranged on the barrel body in a clamping manner; a hollow cavity is arranged in the barrel body; an inlet and an outlet are arranged in the front end and the rear end of the barrel body respectively; a first filter screen and a second filter screen are arranged at the two ends in the barrel body respectively; the drying agent is arranged between the first filter screen and the second filter screen; a first sealing stepped clamping groove is arranged in the front end cover; and a second sealing stepped clamping groove is arranged in the rear end cover. The dry filter disclosed by the invention is simple in structure, compact in design and convenient to use; the front end cover and the rear end cover are detachably connected to the barrel body, so that the drying agent can be conveniently replaced; and the barrel body is connected in a plugging manner instead of a traditional welding manner during an installation process due to the sealing stepped clamping grooves arranged in the front end cover and the rear end cover, so that the dry filter can be cyclically used for many times.

Description

technical field [0001] The invention relates to a dry filter, in particular to a dry filter used in a filtration refrigeration system. 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. During use, the two ends of the dry filter are usually fixedly connected by welding. If there is blockage or damage after the fixed connection, it is difficult to replace, and the whole piece can only be replaced, which is inconvenient to use. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems and provide a dry filter with simple structure and compact design. [0004] The present invention adopts the following technical solutions: a dry filter, including a cylinder body, a front end cover, a rear...
