Abstract
The utility model discloses a dry filter. The dry filter comprises a shell, a molecular sieve and a filter screen, and the molecular sieve and the filter screen are arranged inside the shell. The shell comprises a barrel body and an end cover. The barrel body is provided with a flange connecting part, and the side portion of the flange connecting part is provided with barrel body mounting holes. The middle of the end cover is provided with an inlet end, and the side portion of the end cover is provided with end cover mounting holes. The flange connecting part and the end cover are in screw joint. A sealing ring is installed between the flange connecting part and the end cover in a pressing mode. According to the dry filter, the screw joint mode of the barrel body and the end cover is used, and when the molecular sieve loses efficacy or the filter screen is damaged, maintaining and replacing can be achieved conveniently.
Description
Technical field
The utility model discloses the device for drying and filtering in a kind of refrigeration system.
Background technology
The patent No. is that the Chinese invention patent of ZL201010235004.X discloses a kind of device for drying and filtering, its entrance point and the port of export are all integrally welded with housing, be the structure that can not be split, in case device for drying and filtering damages or is aging, such as filter screen compressive deformation or breakage, the situations such as the dry filter performance reduction of molecular sieve, must change whole device for drying and filtering, maintenance cost is high, particularly in the refrigeration system take carbon dioxide as cold-producing medium, the operating pressure of this system is larger, and existing device for drying and filtering is impaired easily, poor for applicability, need to improve.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of device for drying and filtering easy to maintenance is provided.
For achieving the above object, the technical solution of the utility model is: a kind of device for drying and filtering, comprise housing, be installed in molecular sieve and the screen pack of enclosure interior, described housing comprises cylindrical shell and end cap, described cylindrical shell is provided with the flange connecting portion, described flange connecting portion limit section has the cylindrical shell installing hole, described end cap middle part has entrance point, end cap limit section has the end cap installing hole, described flange connecting portion and end cap connected mode are pressed with sealing ring for being spirally connected between described flange connecting portion and the end cap.
The beneficial effects of the utility model are: be the connected mode that is spirally connected by cylindrical shell and end cap, when molecular sieve lost efficacy or screen pack when damaging, can carry out easily maintain and replace.
Description of drawings
Fig. 1 is profile schematic diagram of the present utility model;
Fig. 2 is fractionation schematic diagram of the present utility model;
Fig. 3 is the cutaway view of A-A direction among Fig. 1.
Among the figure: housing 1, molecular sieve 2, screen pack 3, cylindrical shell 4, flange connecting portion 41, cylindrical shell installing hole 411, end cap 5, entrance point 51, end cap installing hole 52, bolt 6, nut 7, sealing ring 8.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of device for drying and filtering, comprise housing 1, be installed in molecular sieve 2 and the screen pack 3 of housing 1 inside, described housing 1 comprises cylindrical shell 4 and end cap 5, described cylindrical shell 4 is provided with flange connecting portion 41, described flange connecting portion 41 limit sections have cylindrical shell installing hole 411, described end cap 5 middle parts have entrance point 51, end cap 5 limit sections have end cap installing hole 52, described flange connecting portion 41 and end cap 5 connected modes are pressed with sealing ring 8 for being spirally connected between described flange connecting portion 41 and the end cap 5.
Bolt 6 passes end cap installing hole 52 and cylindrical shell installing hole 411, by nut 7 fitted bolts 6 flange connecting portion 41 and end cap 5 is linked together, and be pressed with sealing ring 8 between flange connecting portion 41 and end cap 5, can prevent the leakage of cold-producing medium.After molecular sieve 2 loses efficacy or screen pack 3 when damaging, only need unclamp nut 7, take off bolt 6, and just can take off whole end cap 5, and so just can take out easily molecular sieve 2 or screen pack 3 is changed.
