Summary of the invention
The purpose of the utility model is to propose a kind of device for drying and filtering, and it has the characteristics durable, easy to maintenance, that use cost is low.
The purpose of the utility model can realize through following technical scheme:
A kind of device for drying and filtering; Comprise housing, molecular sieve and filter screen; The entrance point of housing has inlet tube, and the port of export of housing has outlet, is filled with molecular sieve in the housing; Leave a segment distance between molecular sieve and inlet tube and the outlet and pass through the filter screen isolation, it is characterized in that: housing is connected and composed by cylindrical shell and entrance point assembly;
One end of cylindrical shell is the port of export and connects outlet, and the other end of cylindrical shell is an entrance point, and entrance point has the flange connecting portion, and the flange connecting portion is provided with the cylindrical shell installing hole;
The entrance point assembly comprises binding, entrance point shrouding and gasket seal, and the middle part of entrance point shrouding has inlet tube, and the middle part of binding has perforation, and the limit portion of binding is provided with the end plate installing hole;
Entrance point shrouding and gasket seal are between the flange connecting portion of binding and cylindrical shell; Inlet tube on the entrance point shrouding passes from the perforation of binding, and flange connector passes the end plate installing hole of binding and with cylindrical shell installing hole on the cylindrical shell entrance point assembly is connected with cylindrical shell.
Prioritization scheme comprises:
The limit portion both sides of filter screen closely are connected with two filter screen backplates through bolt; Between outlet and filter screen, has the retaining edge in the cylindrical shell near outlet.
In the process of using the utility model, in case filter screen damages or molecular sieve lost efficacy, can unclamp flange connector, the entrance point assembly is separated with housing, take out filter screen or molecular sieve, repair or replace.
The utlity model has following substantive distinguishing features and progress:
1. but housing is the sectional type structure, maintains easily filter screen and molecular sieve in the housing;
2.Have the filter screen that the filter screen backplate is reinforced, not yielding, long service life.
