Replaceable silk screen filtered air cleaner

Abstract

The invention discloses a replaceable silk screen filtered air cleaner. The replaceable silk screen filtered air cleaner comprises a shell upper cover, a filter element assembly, a shell lower cover and an air outlet pipe; a filter material of the filter element assembly is metal wire mesh, a support is arranged on the air outlet pipe and on the inner side of the shell upper cover; a hose clamp isarranged on the air outlet pipe and on the side edge of the support; and the other side of the support is connected with the shell lower cover through combination of a screw rod and a nut. The metalwire mesh is adopted in the filter element assembly, it is guaranteed that enough rust prevention capacity is achieved in a humid environment, and the filtering performance is guaranteed; the integralassembly of the shell upper cover, the shell lower cover and the filter element assembly is realized through the connection of the support and the combination of the screw rod and the nut, an original middle shell part is omitted, the air inlet area of the filter element assembly is maximized, mold development is reduced, the structure is simple, the product assembling efficiency is effectively improved, the filtering effect is obviously improved, clean air is provided, and the overall quality of the air cleaner is improved.

Description

technical field [0001] The invention relates to a filtering facility, in particular to an air filter. Background technique [0002] At present, the air filter for vehicles and ships is a filter facility for the air purification of its intake system, including a housing, a filter element assembly, an air inlet, and an air outlet pipe. The filter element assembly uses filter paper as a filter material. The stiffness is low in the environment, and its filtration performance is easily affected negatively, and a new filter element assembly needs to be replaced after use; the housing is composed of the upper cover of the housing, the middle housing, and the lower cover of the housing. The air intake area of ​​the air inlet of the filter element assembly is increased, and the design and development and investment costs of the mold are increased, and the connection structure of the three is also more complicated. Thus affecting the filtration efficiency of the air filter. Content...
