Detailed description of the invention
Embodiment: referring to Fig. 1, a kind of air cleaner in figure, comprise housing and mend core joint, housing one end is air inlet, the other end is by screw thread and benefit core airtight connection of joint, mend core joint and be provided with gas outlet, described enclosure interior is provided with filter core, the axis cross section of this filter core is W shape, described filter core comprises external conical-tube, inner conical-tube, and upwards, the major part of inner conical-tube is downward for the major part of external conical-tube, between the lower end of inner conical-tube and the lower end of external conical-tube, connect by lower annular end face sealing, the upper end of described inner conical-tube is sealed by upper surface; It between external conical-tube and inner conical-tube, is laying dust chamber; The opening diameter of external conical-tube upper surface is greater than air inlet diameter, and external conical-tube external support has spring, and spring is pressed in the top, upper surface of external conical-tube on the air inlet inner face of housing.
The cross section of described inner conical-tube is petal-shaped.Can expand the filter area of filter core, improve the permeability of filter core.
The external conical-tube outer surface of described filter core is provided with some gib blocks that are slidably matched with shell inner surface, makes to move in filter element shell smooth and easy, and the upper end of described spring is supported on gib block lower end, is gas leakage gap between adjacent gib block; Described lower annular end face bottom is provided with several supporting legs, is gas leakage gap between adjacent supporting leg.After filter core uses for a long time and stopped up by dust, air pressure promotes filter core and sinks, and air can pass through by gas leakage gap, avoids obstructed other accidents that causes of pipeline.
Described air inlet and gas outlet are all provided with quick connector.Can improve the installation rate of this filter.
Fast plug comprises with the fittings body of connecting thread, in fittings body, is provided with sealing ring, lining, cutting ferrule, locking plate, lock core, and flexible pipe is inserted in lock core and is locked by locking plate.
Described filter core is powder metallurgy anti-friction part.
The course of work of this air cleaner:
After this filter is arranged in pipeline, gas enters by air inlet, and the particle carrying in gas or dust are stopped getting off to be deposited in laying dust chamber by filter core, then discharge through gas outlet; If work under bad environment or work long hours after, laying dust chamber is filled, affected the permeability of filter core, air pressure can promote filter core Compress Spring, and the upper surface of the external conical-tube of filter core separates with air inlet end face, gas side leakage, then descending along gas leakage gap, the gas leakage gap through the supporting leg of filter core inner conical-tube bottom, discharges through outlet, so just can avoid because filter core does not cause pipeline interruption thoroughly, thereby avoid occurring the phenomenon of brake failure.
