Description
Technical field
The utility model relates to a kind of closing appliance, particularly a kind of for coal bunker mouth Anti-air-leakage, dustproof automatic closing appliance.
Background technology
Use in the process of down-hole belt-conveying raw coal, in the time that raw coal enters coal bunker, in air-flow, carrying a large amount of coal dusts secretly can be sprayed by Hatch Opening, pollutes whole coal bunker Hatch Opening, the serious threat person and device security.Existing belt lane is located at return airway more in addition, in the time of coal emptying in coal bunker, can cause Air escape branch to cause air supply of working face deficiency, if and not by the coal emptying in coal bunker, in the time that storehouse contains water coal or large spoil and foreign material, may cause and alter storehouse, canopy storehouse, card building phenomenon, and bring great potential safety hazard to the production in colliery.
Summary of the invention
The problem existing for above-mentioned prior art, it is a kind of for coal bunker mouth Anti-air-leakage, dustproof automatic closing appliance that the utility model provides, in the time that down-hole belt-conveying raw coal enters coal bunker, effectively prevent dust pollution coal bunker mouth in air-flow, and in the time of coal bunker emptying, avoid occurring Air escape branch and cause air feed deficiency, ensure normally carrying out of production.
To achieve these goals, what the utility model adopted is a kind of for coal bunker mouth Anti-air-leakage, dustproof automatic closing appliance, comprise belt and provide the work drive motor of power for belt operation, also comprise coal bunker body, the upper Hatch Opening of coal bunker body is provided with dash plate, the downside of dash plate is provided with the stay bearing plate of sealing Hatch Opening, on described stay bearing plate, has closing door, and closing door is positioned under dash plate;
The electromagnetic valve coordinating with work drive motor, the cylinder being connected with electromagnetic valve are installed in described coal bunker body, are connected to steel rope on cylinder, steel rope is walked around pulley and is connected with closing door.
Further, stay bearing plate is encapsulated in Hatch Opening surface on coal bunker body, taking plank or metal sheet as material.
Further, dash plate is that one end is fixed on Hatch Opening on coal bunker body, the elastic plate that the other end can up-and-down movement, and elastic plate surface has some through holes.
Preferably, some through holes are symmetricly set on elastic plate both sides.
Compared with prior art, this closing appliance is opened cylinder in the time that belt moves, and by pulley tense wire rope, closing door is opened, and the raw coal frontal impact dash plate moving on belt feeder is fallen in coal bunker by sealing door-plate; In the time that belt is out of service, cylinder is closed, and by the pulley steel rope that comes loose, closing door is closed, prevent from causing air supply of working face deficiency because coal bunker emptying causes Air escape branch, and the problem of coal bunker mouth airborne dust when belt feeder operation.
This apparatus structure is simple, easy to operate, and degree of automation is high, during for mine transport raw coal, reliable, efficiently solves dust pollution coal bunker mouth, and Air escape branch occurs when coal bunker emptying and cause the problems such as air feed deficiency, and what ensure to produce normally carries out; Use this device through on-the-spot test, dust emission and race air quantity obviously decline, and dust emission is reduced to 3.12 mg/min by original 50mg/min, runs air quantity by original nearly 800m
3/ min is reduced to 2m
3/ min, Anti-air-leakage, dust-proof effect are remarkable.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of for coal bunker mouth Anti-air-leakage, dustproof automatic closing appliance, comprise belt 1 and provide the work drive motor 2 of power for belt 1 operation, also comprise coal bunker body 4, the upper Hatch Opening of coal bunker body 4 is provided with dash plate 3, the downside of dash plate 3 is provided with the stay bearing plate 5 of sealing Hatch Opening, on described stay bearing plate 5, has closing door 6, and closing door 6 is positioned under dash plate 3;
The electromagnetic valve coordinating with work drive motor 2, the cylinder 8 being connected with electromagnetic valve are installed in described coal bunker body 4, are connected to steel rope 9 on cylinder 8, steel rope 9 is walked around pulley 7 and is connected with closing door 6.
As further improvement of the utility model, stay bearing plate 5 is encapsulated in Hatch Opening surface on coal bunker body 4, taking plank or metal sheet as material, by Hatch Opening sealing, effectively control raw coal and enter the space of coal bunker by stay bearing plate 5, while avoiding that space is excessive causes raw coal to enter coal bunker, dust sprays on a large scale and pollutes coal bunker mouth, select plank or the metal sheet material as stay bearing plate 5, raw material is easy to get simultaneously, and cost of installation is low.
As further improvement of the utility model, as shown in Figure 3, dash plate 3 is fixed on Hatch Opening on coal bunker body 4 for one end, the other end can up-and-down movement elastic plate, elastic plate surface has some through holes, preferred through hole is symmetricly set on elastic plate surface, when belt 1 transports raw coal to coal bunker mouth, raw coal frontal impact dash plate 3 is fallen in coal bunker body 4 by sealing door-plate, dash plate 3 is between raw coal and coal bunker mouth, can effectively alleviate raw coal whereabouts gravity, while making raw coal enter into coal bunker mouth, can not spend and cause greatly dust to vomit because of falling force, avoid pollution coal bunker mouth, be symmetrical arranged some through holes on dash plate 3 surfaces simultaneously, can make part raw coal by dropping under through hole in coal bunker, symmetrical through hole ensures that dash plate 3 is subject to raw coal impulse force even, prevent that the excessive dash plate 3 that causes of local pressure from tilting, affect raw coal service direction.
When use, first dash plate 3 is arranged on to coal bunker mouth, at 3 times side packing planks of dash plate or metal sheet, then on plank or metal sheet, offers closing door 6, the position of closing door 6 need be located at dash plate 3 under; Simultaneously at the interior installation electromagnetic valve of coal bunker body 4, cylinder 8, steel rope 9, pulley 7, wherein electromagnetic valve coordinates with work drive motor 2, when motor moves or cuts out, controlling electromagnetic valve opens or closes accordingly, the action that the cylinder 8 being connected with electromagnetic valve also opens or closes accordingly, there is tension or the action that comes loose in the steel rope 9 that connects subsequently cylinder 8, realizes the control to closing door 6 open and close states.
Therefore, in the time that work drive motor 2 drives belt 1 to move, the solenoid control cylinder 8 being connected with motor is opened, by pulley 7 tense wire ropes 9, closing door 6 is opened, in belt 1, after the raw coal frontal impact dash plate 3 of transport, fall in coal bunker body 4 again the problem of coal bunker mouth airborne dust while preventing belt feeder operation by sealing door-plate; In the time that work drive motor 2 cuts out, belt 1 is out of service, and the solenoid control cylinder 8 being connected with motor is closed, and the steel rope 9 connecting on cylinder 8 comes loose after action by pulley 7, closing door 6 is closed, prevent from causing air supply of working face deficiency because coal bunker emptying causes Air escape branch.
