Problems solved by technology

After the gas filter of this structure is used for a period of time, the following disadvantages can occur: because the magazines for filtering the gas will squeeze through the metal filter screen, so the mesh of the metal filter screen will become larger with the increase of the use time, and also That is to say, the filtering precision of the filter becomes lower and the filtering effect becomes worse.

Abstract

The invention relates to the technical field of filters, and in particular to a composite gas filter which comprises a shell (1) and a connector (2), and further comprises a propping sleeve (6), a bottom ring component (7), a first filtering net component (8), a sintering filter core (9) and a first elastic part (10), wherein a mounting groove (3) is formed inside the shell (1); a groove (4) is formed in the connector (2); the bottom ring component (7) is connected inside the mounting groove (3) in a clamping manner; the propping sleeve (6) is positioned inside the groove (4); the first filtering net component (10) is positioned inside the propping sleeve (6); the top end of the first filtering net component (8) is propped against an end part of the propping sleeve (6); when the connector (2) is tightly screwed with the shell (1), the top end of the first filtering net component (8) is propped against the bottom ring component (7) through the propping sleeve (6); the sintering filter core (9) is positioned inside the first filtering net component (8). By adopting the structure, the composite gas filter that the filtering net component is not liable to damage and thus the filtering effect can be stable is provided.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a composite gas filter. Background technique [0002] Gas filters are widely used in electrical work systems to filter large particles of impurities in the gas, to ensure the purity of the gas input to components, and to avoid damage to components by impure gases. [0003] The gas filter in the prior art generally includes a housing and a joint. The housing and the joint are provided with gas through holes. The housing and the joint are threaded. network. After the gas filter of this structure is used for a period of time, the following disadvantages can occur: because the magazines for filtering the gas will squeeze through the metal filter screen, so the mesh of the metal filter screen will become larger with the increase of the use time, and also That is to say, the filtering precision of the filter becomes lower and the filtering effect becomes worse. Contents of the inve...
