Abstract

The invention discloses a double-layer filter screen convenient to connect. The double-layer filter screen convenient to connect comprises an upper framework, a filter screen and a lower framework. The filter screen is arranged between the upper framework and the lower framework. The lower framework comprises a disc, a first annular sleeve and a second annular sleeve, wherein the first annular sleeve and the second annular sleeve are arranged at the two ends of the disc respectively, a connecting thread is arranged on the inner wall of the first annular sleeve, a plurality of round holes are formed in the surface of the disc, first-layer filter screens are arranged in the round holes respectively, and an annular groove is formed in the end face of the second annular sleeve. An annular protruding strip corresponding to the annular groove is arranged on the end face of one end of the upper framework, and a connecting thread is arranged on the outer wall of the other end of the upper framework. In this way, according to the double-layer filter screen convenient to connect, the filter screens can be conveniently replaced, and the filter screens and external connecting pipelines can be conveniently disassembled or assembled; meanwhile, the service life of the filter screens or the filter time of the filter screens is prolonged, the filter screen replacement frequency is reduced, and the life cycle of equipment is prolonged.

Description

technical field [0001] The invention relates to a filter net, in particular to a conveniently connected double-layer filter net. Background technique [0002] The filter screen, referred to as the filter screen, is made of wire mesh with different meshes. Its function is to filter the molten material flow and increase the resistance of the material flow, so as to filter out mechanical impurities and improve the effect of mixing or plasticizing. [0003] Filters are often used in air conditioners or refrigerators to filter impurities, sundries, dust, etc. in the system to prevent "dirty blockage". The general filter screen is directly placed at both ends of the dry filter. On the one hand, the connection between the filter screen and the drier is cumbersome, and the installation is inconvenient; If the filter is damaged, the filter will fail, which will affect the normal use of the equipment. Contents of the invention [0004] The technical problem mainly solved by the pr...
