Abstract
The utility model relates to a random spray dust laying and dust removing device for impeller coal feeders, which is composed of a water supply pipe supporting frame, rubber water supply pipe, a nozzle at an impeller coal sweeping position, a metal water supply pipe, a seal cover, a dust sucking pipe, a blower fan, a dust collecting box, a dust remover, a chute outlet nozzle and a chute outlet curtain baffle. A supporting frame with lightweight steel structure and a plastic sunlight plate are utilized to form the seal cover in a working zone of a coal feeder, and the seal cover is sealed to prevent powder dust from escaping. An impeller coal sweeping position and a chute outlet are sources generating powder dust, and the fine spraying nozzle is arranged to form a thin mist film on a coal seam to lower the concentration of the powder dust. The rubber curtain baffle is additionally arranged at the chute outlet to prevent coal and powder dust from rushing out from the chute outlet because of large drop height and induced air when coal falls to the chute outlet, so that the generation of powder dust is controlled. Part of power dust drifting in the seal cover can be sucked and removed through the dust remover, the pipe and the blower fan system.
Description
The utility model relates to a kind of paddle coal feeder atomizing de-dusting, dust collector at random, belongs to the industrial dedusting device.
Navigation coal is transported to after the Railway station, adopts tipper that coal is discharged to underground coal hopper usually, and the coal hopper bottom is exactly a paddle coal feeder, by paddle coal feeder coal is pushed chute again, falls belt transporter by the outlet of chute, is transported to other places again.Dial at impeller and can produce a large amount of dust when coal point and coal are fallen belt feeder by the elephant trunk outlet.In the work place of feeder, because dust concentration is very high, visbility has only 2～3 meters.So big dust concentration not only has a strong impact on workman's physical and mental health, also sets off an explosion accidents such as fire easily.This problem is perplexing the safety in production of paddle coal feeder work stall always and is carrying out production strictly in line with rules and regulations.
The measure of taking at the paddle coal feeder work stall mainly is a water spray dust at present, the one, and water consumption is big, and the 2nd, the aqueous ingredients of increase coal also can influence transportation because the increase of aqueous ingredients can reduce the calorific value of coal.And dust removing effects and bad.
The purpose of this utility model is that a kind of paddle coal feeder atomizing de-dusting at random, dust collector will be provided.
The purpose of this utility model is achieved in that at first utilizing light section steel structure support and plastics sunlight board to make seal closure seals it, prevents flour dust overflow in feeder work section; Impeller dials coal point and the chute outlet is the source that produces dust, and the fine injection nozzle is set, and sprays 0.1～0.3 millimeter droplet, small droplet is caught tiny dust easily, drop to after the cohesion on the coal seam, on the coal seam, form very thin mist film, reduce the concentration of dust greatly; Set up the rubber check apron in chute outlet, prevent coal when impeller is dialled the coal point and dropped to the chute outlet, big and induced air makes coal and dust outwards be gone out by outlet because of drop, thereby reduces being scattered and the increase of dust of coal; Drift about dust in seal closure of part can pass through dust exhaustor, pipeline, blower fan system, and dust is absorbed.
Feeder is operation between a plurality of coal hoppers, miles of relative movement reaches tens meters, water supply pipe adopts the rubber tube coiled, be placed on and move back and forth elongation on the support, shorten, nozzle and metal water-supply pipe are fixed on the feeder, nozzle is moved with feeder, and nozzle will remain on the optimum position of atomizing de-dusting always.
Be described further below in conjunction with accompanying drawing,
Fig. 1 is a structural front view of the present utility model
Fig. 2 is the A-A cutaway view among Fig. 1
Wherein 1, the feed pipe support, 2, the rubber feed pipe, 3, impeller dials coal point nozzle, 4, metal water-supply pipe, 5, seal closure, 6, the dust suction pipeline, 7, blower fan, 8, disposal box, 9, dust exhaustor, 10, the chute outlet nozzle, 11, chute outlet check apron, 12, feedwater cuts down door.
Paddle coal feeder atomizing de-dusting, dust collector is at random dialled coal point nozzle 3, metal water-supply pipe 4, seal closure 5, dust suction pipeline 6, blower fan 7, disposal box 8, dust exhaustor 9, chute outlet nozzle 10, chute outlet check apron 11 and feed-water valve 12 by feed pipe support 1, rubber feed pipe 2, impeller and is formed.Seal closure 1 all seals the afterbody of paddle coal feeder work area and belt feeder, and the power lead of feed pipe support 1, feeder should be installed in the seal closure 1.Dust exhaustor 9, dust suction pipeline 6, blower fan 7, disposal box 8 are installed in the outside of seal closure 5.Rubber feed pipe 2 links with metal water-supply pipe 4, and metal water-supply pipe 4 is dialled coal point nozzle 3 with impeller, chute outlet nozzle 10 is thread connection, and flooding quantity is by feed-water valve 12 controls.Impeller is dialled coal point nozzle 3 and is positioned at impeller and dials coal point place, and spraying can cover the zone that produces dust; Chute outlet nozzle 10 is positioned at the chute outlet, and spraying can cover the outlet of chute.All install chute outlet check apron 11 around the chute outlet, along the both sides installing roman formula check apron of belt feeder direction of travel, the both sides installing vertical with the belt feeder direction of travel has the bar shaped check apron of clip.Result of implementation shows: simple in structure, and small investment, instant effect, reliable.
