The utility model content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of dust arrester with final dusting function is provided, and can greatly reduce the dustiness in the crushed material after the dedusting.
For solving above technical problem, a kind of dust arrester with final dusting function of the present utility model, comprise cyclone separator, the circle wall of described cyclone separator is provided with material inlet, the lower end of described cyclone separator is provided with material outlet, the top center of described cyclone separator is provided with dust and takes over, and the upper port that described dust is taken over is connected with main dust sucting pipeline; The material outlet of described cyclone separator is connected with rotary valve, the below of described rotary valve is provided with secondary filter, the charging aperture of described secondary filter is connected with the outlet of described rotary valve, and the exhaust outlet of described secondary filter is communicated with described main dust sucting pipeline by the secondary dust sucting pipeline.
With respect to prior art, the utility model has been obtained following beneficial effect: crushed material enters the cyclone separator from material inlet, under centrifugal force and self gravitation effect that whirlwind produces, crushed material moves downward to material outlet along the circle wall of cyclone separator, enter secondary filter through rotary valve, rotary valve can make material pass through, and also plays simultaneously the pass wind action, and the gas circuit of cyclone separator and secondary filter is sealed mutually; Dust in secondary filter in the crushed material is by Re-isolation, and crushed material is purified; Because the suction function of dust sucting pipeline, the dust that cyclone separator and secondary filter are separated all enters dust sucting pipeline with air-flow.
As preferred version of the present utility model, the lower port that described dust is taken over is provided with filter screen.Lighter dust can enter dust sucting pipeline by filter screen, and filter screen can prevent effectively that crushed material from entering dust sucting pipeline, avoids the waste of crushed material.
As further preferred version of the present utility model, described secondary filter comprises interconnective top cylindrical shell and bottom cylindrical shell, described exhaust outlet is connected on the circle wall of described top cylindrical shell, be provided with the conical pipe with top cylindrical shell coaxial line in the cylindrical shell of described top, it is outer as described charging aperture that the upper port of described conical pipe is stretched out the top cylindrical shell, be provided with height low arc plate all around in center under the described conical pipe, the lower port of described bottom cylindrical shell is shunk as discharging opening to axis, and the upper port of described bottom cylindrical shell is provided with a plurality of air admission holes and each air admission hole and evenly distributes along the lower end periphery of described top cylindrical shell.Crushed material falls into from conical pipe, fall the middle part at arc plate, then from the peripheral landing of arc plate, discharge from discharging opening at last, crushed material is when falling, and dust is kicked up, because the negative pressure swabbing action of main dust sucting pipeline, air-flow enters secondary filter from air admission hole, and the dust of kicking up is taken out of, and crushed material is further purified.
