Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of backing plate of the present utility model.
In figure: housing 1, flange 11, end cap 2, open tube 21, protect edge 22, backing plate 3, through hole 31,
Active carbon layer 4, desiccant layer 5, foam ceramic filter layer 6, spring 7, filter screen 8.
Detailed description of the invention
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is made the most concrete
Explanation.
As shown in Figure 1 and Figure 2, the device for drying and filtering of convenient maintenance, including housing 1, housing 1 is opened for two ends
Mouthful and the cylindrical structure of inner hollow, described housing 1 two ends are spirally connected end cap 2, and the outer rim of described end cap 2 sets
Have and perpendicular ring-type protect edge 22, described in protect edge 22 and be connected with the outer wall thread of housing 1 end.
Housing 1 inwall middle is provided with flange 11, and flange 11 is circular, fits in described flange 11 both sides
Being provided with backing plate 3, described backing plate 3 is provided with through hole 31, is provided with active carbon layer 4 between two backing plates 3, the most alive
Property layer of charcoal 4 is located at the inside of flange 11.
Opposite side relative with side, active carbon layer 4 place on two backing plates 3 is respectively equipped with desiccant layer 5 and bubble
Foam ceramic filter layer 6, between described desiccant layer 5 and adjacent end cap 2, foam ceramic filter layer 6 and phase
Be equipped with spring 7 and filter screen 8 between adjacent end cap 2, described filter screen 8 between spring 7 and end cap 2,
Filter screen 8 is crimped between the end face of housing 1 and the inwall of end cap 2, and the diameter of filter screen 8 is more than housing 1
Internal diameter and less than the external diameter of housing 1 so that filter screen 8 can be placed at housing 1 end face and will not be to housing 1
Impact with protecting being spirally connected of edge 22, simultaneously the fixing good reliability of filter screen 8, will not be because of the work of spring 7
Firmly and angular displacements, the external diameter of described spring 7 and the internal diameter of housing 1 are equal, spring 7 during use
Will not circumference play, improve reliability of operation, spring 7 is by the filter screen 8 of both sides and foam ceramic filter
Layer 6, filter screen 8 and desiccant layer 5 are compacted, filter, purify, drying effect good.
The center of described end cap 2 is provided with open tube 21, owing to the utility model is that two ends are symmetrical, is installing
Journey needs not distinguish between entrance end, can arbitrarily install, after installing, will be close to foam ceramic filter layer 6
Side as entrance point, opposite side is as the port of export.
Good filter effect can be reached, by work by former and later two filter screens 8 and foam ceramic filter layer 6
Property layer of charcoal 4 and desiccant layer 5 can play and purify and the effect of dry air, the most each part design is reasonable,
Take full advantage of the space in housing 1, and former and later two filter screens 8, foam ceramic filter layer 6, active carbon layer
4 and desiccant layer 5 the most separated by a distance, will not interfere with each other.
The foregoing is only the utility model preferably detailed description of the invention, but protection domain of the present utility model
It is not limited thereto, the technical scope that any those familiar with the art discloses at the utility model
In, the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.
