Detailed description of the invention
Embodiment: see Fig. 1, a kind of air cleaner in figure, comprise housing and mend core joint, shell one end is air inlet, the other end is connected with benefit core joint is airtight by screw thread, 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, closed by lower annular end face between the lower end of inner conical-tube and the lower end of external conical-tube and connect, the upper end of described inner conical-tube is closed by upper surface; It is laying dust room between external conical-tube and inner conical-tube; The opening diameter of external conical-tube upper surface is greater than air inlet diameter, and external conical-tube external support has spring, and top, the upper surface of external conical-tube is pressed on the air inlet inner face of housing by spring.
The cross section of described inner conical-tube is petal-shaped.The filter area of filter core can be expanded, improve the permeability of filter core.
The external conical-tube outer surface of described filter core is provided with some gib blocks be slidably matched with shell inner surface, and make motion in filter element shell smooth and easy, the upper end of described spring is supported on gib block lower end, is gas leakage gap between adjacent gib block; Being provided with several supporting legs bottom described lower annular end face, is gas leakage gap between adjacent supporting leg.After filter core Long-Time Service is blocked by dust, air pressure promotes filter core and sinks, and air can be passed through by the gap that leaks gas, and avoids that pipeline is obstructed causes other accidents.
Described air inlet and gas outlet are all provided with quick connector.The installation rate of this filter can be improved.
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:
When this filter is arranged on after in pipeline, gas is entered by air inlet, and the particle carried in gas or dust are stopped by filter core and be deposited in laying dust room, then discharge through gas outlet; If work under bad environment or after working long hours, laying dust room is filled, have impact on 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 is separated with air inlet end face, gas side leakage, then along gas leakage gap descending, through filter core inner conical-tube bottom supporting leg gas leakage gap, through outlet discharge, so just can avoid because filter core does not cause pipeline to interrupt thoroughly, thus avoid the phenomenon occurring brake failure.
