Abstract
The invention relates to a coal bunker capable of preventing chute blockage and coal agglomeration. The technical problem to be solved by the invention is to provide a coal bunker capable of preventing chute blockage and coal agglomeration. The coal bunker capable of preventing chute blockage and coal agglomeration can alleviate the labor intensity of workers and risk during clearance as well as avoid fatal accident of burning a coal feeder. In order to solve the technical problem, the technical scheme provided by the invention is that the coal bunker capable of preventing chute blockage and coal agglomeration comprises a coal bunker, a loosen machine, and a hydraulic stop valve. The coal bunker is cone-shaped. The loosen machine is arranged in a cone part at the lower part of the coal bunker. The hydraulic stop valve is arranged at a coal outlet of the coal bunker. The lower part of the hydraulic stop valve is connected with the coal feeder through an inlet short piece. The hydraulic stop valve is connected with a controller. According to the coal bunker capable of preventing chute blockage and coal agglomeration provided by the invention, the coal feeding quality is greatly improved, and phenomena of smoke fleeing, rise of outlet temperature and manual clearance can be avoided; chute blockage and coal agglomeration are eliminated; the fatal accident of burning the coal feeder is thoroughly eliminated, the cost is saved, and the benefit and safety are improved.
Description
Technical field
The present invention relates to a kind of coal bunker that prevents chute blockage and canopy coal.
Background technology
Existing coal bunker caking, obstruction, canopy coal phenomenon take place frequently, and the boiler adjustment is difficult to normal realization, can't satisfy the burden requirement of scheduling; Combustion-supporting big with oil mass, rate of load condensate is low, and economic operation level is low; Run coal bin forms exhaust gases passes, and furnace high-temperature flue gas anti-channeling is prone to cause feeder and belt to burn out; Coal-supplying amount is unstable, causes coking in the stove, deslagging not smooth; Bed is pressed high, is prone to cause the compelled stoppage in transit of boiler; Personnel get into and often excavate the long-pending coal of cleaning in the storehouse, exist bigger personal safety hidden danger.
Summary of the invention
Danger when the technical matters that the present invention solved provides a kind of coal bunker that prevents chute blockage and canopy coal and can alleviate working strength of workers by chance and bring down stocks, the serious accident of avoiding burning feeder takes place.
For solving above-mentioned technical matters, the technical scheme that the present invention takes:
Prevent the coal bunker of chute blockage and canopy coal; Its special character is: comprise coal bunker, loose machine, hydraulic pressure pipe valve, described coal bunker is conical, in the bottom centrum part of coal bunker loose machine is set; The coal bunker coal outlet is provided with the hydraulic pressure pipe valve, and hydraulic pressure pipe valve bottom is connected with feeder through the inlet pipe nipple; Described hydraulic pressure pipe valve is connected with controller.
The bulkhead of above-mentioned coal bunker and horizontal plane angle are more than or equal to 73 degree.
The inwall of above-mentioned coal bunker is provided with liner plate.
The scraping blade of above-mentioned loose machine adopts the blade of punching structure property.
Compared with prior art, coal supply quality of the present invention increases substantially, and prevents the phenomenon that flue gas anti-channeling, temperature out raise, manual work is brought down stocks; Eliminating chute blockage and canopy coal phenomenon takes place; Thoroughly eliminate the serious accident generation that feeder burns, practice thrift cost, increase the benefit and safety.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is elaborated.
Referring to Fig. 1; The present invention includes coal bunker 1, loose machine 2, hydraulic pressure pipe valve 3, described coal bunker 1 is conical, in the bottom centrum part of coal bunker 1 loose machine 2 is set; Coal bunker 1 coal outlet is provided with hydraulic pressure pipe valve 3, and hydraulic pressure pipe valve 3 bottoms are connected with feeder through inlet pipe nipple 4; Described hydraulic pressure pipe valve 3 is connected with controller.
The bulkhead of above-mentioned coal bunker 1 and horizontal plane angle are spent more than or equal to 73, and all are circular arc cambers, have well solved the problem of the long-pending coal of rectangle coal bunker angle.
The inwall of above-mentioned coal bunker 1 is provided with liner plate; Liner plate adopts the thick corrosion-resistant steel liner plate of 3mm; Liner plate and bulkhead adopt plug welding, and the corrosion-resistant steel liner plate can be as glass cermaic plate because of lining cement be not aging, bulkhead beats and comes off, also can the sanding of image height molecular material liner plate, the great number of issues of distortion takes place; The corrosion-resistant steel liner plate has the smooth more characteristics of mill more, and long service life.
The scraping blade of above-mentioned loose machine 2 adopts the blade of punching structure property, and loose machine blade is yielding before can solving, phenomenons such as the easy bending of pull bar.
