Abstract
The invention discloses a coal dust filter unit of a boiler ribbon conveyor. The coal dust filter unit comprises a conveying belt, a turning and selecting jam is arranged above the conveying belt in an inclined manner, the lower end of the turning and selecting jam is parallel to the surface of the conveying belt, the upper end of the turning and selecting jam is connected with a sliding groove, the sliding groove is arranged in the same direction with the turning and selecting jam in the inclined manner, a conveyor belt A is arranged below the upper end of the sliding groove and inclines upwardly, a conveyor belt B is arranged horizontally below the upper end of the conveyor belt A, and one end of the conveyor belt B extends out of the ribbon conveyor. With the coal dust filter unit of the boiler ribbon conveyor, the turning and selecting jam is inserted into coal dust on the conveying belt and the coal dust can be cleaned by the turning and selecting jam lie a comb, so that non-iron impurity in the coal dust can be filtered on the turning and selecting jam, and the non-iron impurity are conveyed to a waste recovery box through the conveyor belt A and the conveyor belt B; the non-iron impurity in the coal dust can be effectively removed, an entry end of a boiler feeder can be free of being blocked, hot smokes in the boiler do not be blown to burn the belt, and picking workload of operators is reduced and working condition is improved.
Description
Technical field
The present invention relates to boiler original ribbing formula feedway, especially a kind of coal powder filter of fluidized-bed combustion boiler belt conveyer.
Background technology
The raw coal that present coal burning boiler uses arrives the coal storage point by the communications and transportation mode mostly, for meeting the boiler operating needs, usually raw coal through transmission, broken, be transferred to feed bin and enter boiler, before entering crusher, through deironing, process, but after having in transit the non-iron things such as wooden unit, knitting and can entering crushing system, enter belt conveyer thereupon and send into coal bunker, can cause in the coal feeder of boiler inlet end plugged, cause disconnected coal, affect boiler and normally move.And existing most of weighing coal feeders all adopt boiler fan to provide sealing air to guarantee in feeder to be malleation, to prevent that in stove, hot flue gas anti-channeling burns out belt, after entering once foreign material, can cause at cleaning feeder entrance foreign material, existence, because feeder outlet flashboard fits badly, brings the dangerous risk of the larger person and equipment.
Summary of the invention
For the deficiencies in the prior art part, the present invention aims to provide a kind of coal powder filter of boiler belt conveyer, guarantees to remove the non-iron foreign material on belt conveyer comprehensively.
The technical solution used in the present invention: a kind of coal powder filter of boiler belt conveyer, comprise belt conveyor, be obliquely installed above belt and turn over the choosing fork, turn over choosing fork lower end parallel with belt surface, in the upper end of turning over the choosing fork, connect chute, chute also with turn over choosing and pitch and be obliquely installed in the same way, load-transfer device A is set below the chute upper end, load-transfer device A is inclined upwardly, horizontally set load-transfer device B below the upper end of load-transfer device A, and load-transfer device B mono-end extends belt conveyer.
Adopt said apparatus, turn over choosing fork front end basic parallel with belt, rear end is inclined upwardly, turning over choosing fork front end inserts in the coal dust on belt, because coal dust moves forward with belt, turn over choosing fork as comb by the coal dust combing, the non-iron foreign material in coal dust are filtered and pitch turning over choosing like this, along with the non-iron foreign material that turn over the filtration of choosing fork increase
Non-iron foreign material enter load-transfer device A along chute, and load-transfer device A is delivered to load-transfer device B by non-iron foreign material again, and load-transfer device B is delivered to non-iron foreign material in the waste recovery frame.
This apparatus structure is simple, and working stability is reliable, can effectively remove the non-iron foreign material in coal dust, prevents the coal feeder of boiler inlet end plugged, stops hot flue gas anti-channeling in stove simultaneously and burns out belt, alleviates personnel and picks up work capacity, improves working conditions.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is for turning over choosing fork structural representation;
In accompanying drawing: 1 turns over choosing fork 2 chute 3 load-transfer device A 4 load-transfer device B 5 belts.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
A kind of coal powder filter of boiler belt conveyer, comprise belt conveyor 5, be obliquely installed above belt 5 and turn over choosing fork 1, turn over choosing fork 1 lower end parallel with belt 5 surfaces, connect chute 2 in the upper end of turning over choosing fork 1, chute 2 also with turn over choosing fork 1 and be obliquely installed in the same way, the angle of inclination can be the same in the same way with turning over choosing fork 1 for chute 2, the angle perhaps tilted reduces relatively, on belt 5 during pulverized coal conveying, turning over choosing fork 1 inserts in coal dust, turn over choosing fork 1 just as comb the non-iron foreign material filtering in coal dust, along with the non-iron foreign material of filtering increase, non-iron foreign material are pushed mutually, along chute 2, move up, below chute 2 upper ends, load-transfer device A3 is set, load-transfer device A3 is inclined upwardly, horizontally set load-transfer device B4 below the upper end of load-transfer device A3, like this, when non-iron foreign material are moved upwards up to top along chute 2, non-iron foreign material fall on load-transfer device A3, load-transfer device A3 is delivered to load-transfer device B4 by non-iron foreign material, load-transfer device B4 mono-end extends belt conveyer, finally non-iron foreign material are delivered in the waste recovery frame.
Claims (1)
1. the coal powder filter of a boiler belt conveyer, comprise belt conveyor (5), it is characterized in that: in belt (5) top, be obliquely installed and turn over choosing fork (1), turn over choosing fork (1) lower end parallel with belt (5) surface, connect chute (2) in the upper end of turning over choosing fork (1), chute (2) also with turn over choosing fork (1) and be obliquely installed in the same way, below in chute (2) upper end arranges load-transfer device A(3), load-transfer device A(3) be inclined upwardly, at load-transfer device A(3) upper end below horizontally set load-transfer device B(4), load-transfer device B(4) end extends belt conveyer.
