Abstract
The utility model relates to a pulverized coal conveyor, which comprises a rack. A coal hopper and a coal outlet pipe are arranged on the rack. A feed opening is arranged at the bottom end of the coal hopper. The pulverized coal conveyor is characterized in that a pulverized coal conveyor belt is arranged below the feed opening, a coal discharge position at the front end of the pulverized coal conveyor belt is connected with the coal outlet pipe, a gate which is used for controlling pulverized coal flow is arranged on the side wall of the coal hopper adjacent to one side of the coal outlet pipe, and one side of the coal outlet pipe is connected with a blower. By reasonably arranging the pulverized coal conveyor belt, the gate, a coal outlet, the blower and the like, the process of jetting pulverized coal to a position above a combustion area in a boiler body at high speed to support combustion is realized. When the pulverized coal conveyor is used, the pulverized coal is jetted to the position above the combustion area in the boiler body through the blower and is in contact with the combustion body of the combustion area, the pulverized coal and the combustion body are fully combusted, temperature in a boiler is increased, radiation strength is enhanced and the working efficiency of the boiler body is improved. When the pulverized coal conveyor is used with the boiler, compared with the combustion of a common boiler, approximately 35 percent of coal can be saved. The pulverized coal conveyor is high-efficiency energy-saving equipment and can be widely popularized.
Description
Technical field
The utility model relates to a kind of boiler aid, especially a kind of coal dust conveyer that helps the coal-burning boiler efficient burning.
Background technology
The coal that present coal-burning boiler burning is used mostly is the system coal, because system coal specification is not of uniform size, wherein contain a large amount of coal dusts, and coal dust amasss all usually in the fire grate bottom, and burning is insufficient easily during burning is just got rid of as slag, thereby causes waste.More existing on the market at present coal dust firing special equipments because coal dust firing is too fast, cause fuel value low excessively easily, and make it be suitable for miniature boiler and use, and these coal dust firing special equipment complex structures, be unsuitable for regular maintenance and use.The patent No. is that CN201020127507.0 discloses a kind of coal-fired body of heater coal dust mixed combustion conveyer, comprise feed cylinder, be provided with spiral feeding axis in the feed cylinder, the feed cylinder end is provided with feed opening, it is characterized in that: the feed opening place is provided with blanking tube, and the blanking tube two bottom sides is respectively equipped with air blast, the jet that is complementary.This coal dust conveyer adopts spiral feeding axis to come feeding, and coal dust causes the coal dust feed flow inhomogeneous also continuing blanking when starting spiral feeding axis for the second time easily when the drive motors of spiral feeding axis is shut down, and result of use is bad.Can only before the drive motors of spiral feeding axis is shut down, close the blanking gate of coal bunker in actual applications or after drive motors starts, open coal bunker blanking gate, just can avoid the uneven situation of coal dust feed flow, use very inconvenient.Therefore be badly in need of occurring a kind of coal dust conveyer that can improve the interior coal dust firing efficient of boiler and be applicable to most coal-burning boilers, improve the thermal conversion efficiency and the energy-saving effect of boiler.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of coal dust conveyer that the coal dust firing utilization rate was used and can be improved in practical operation of being convenient to is provided.
The utility model solves the technical scheme that its technical problem adopts: this coal dust conveyer, comprise frame, frame is provided with coal bunker, coal output pipe, the coal bunker bottom has feed opening, the feed opening below is provided with the coal dust conveyer belt, the front end blanking place of coal dust conveyer belt is connected with coal output pipe, and coal bunker is provided with the gate that is used to control pulverized coal flow near the sidewall of coal output pipe one side, and coal output pipe one side is connected with air blast.During work, coal dust drops on the coal dust conveyer belt by feed opening, carries toward coal output pipe again, and coal dust is controlled flow via the gate restriction in the way, thereby avoids coal dust to carry uneven problem.After coal dust falls into coal output pipe, by air blast coal dust is blown into combustion zone top in the boiler at a high speed again, contact with combustion zone internal combustion body, fully burn, improve the interior temperature of stove, enhanced rad intensity has improved the operating efficiency of body of heater.
Further, the gate side is provided with tooth bar, and the coal bunker sidewall is provided with handwheel, and hand wheel shaft is connected to gear, and wheel and rack is connected by meshing transmission.Like this, rotate the size that the gate opening is set by handwheel as required, be convenient to control the flow of coal dust, start, can not influence pulverized coal flow even the back is shut down or shut down to motor, simple to operate.Coal output pipe tiltedly is located on the frame and with the blanking place of coal dust conveyer belt and is connected.The coal output pipe hypomere has bending structure, and described air blast is communicated with the bending structure coupling.So not only be convenient to coal dust, also be convenient to coal dust is ejected coal output pipe.Below, coal dust conveyer belt rear end is connected to ash dropping hopper.Can drop in the ash dropping hopper and reclaim being bonded at grey shape thing on the coal dust conveyer belt like this, use environmental protection more.
The effect that the utility model is useful is: of the present utility model rational in infrastructure, simple, rationally be provided with by coal dust conveyer belt, gate, coal outlet, air blast etc., and realize the process of coal dust high velocity jet to top, boiler furnace internal combustion district auxiliary combustion.During use, coal dust is injected into boiler furnace internal combustion district top by air blast, contact with the combustion body of combustion zone, and coal dust and combustion body are fully burned, and improves the interior temperature of stove, and enhanced rad intensity has improved the operating efficiency of body of heater.Originally be that utility model cooperates boiler to use back comparing with the plain cylindrical furnace burning to economize on coal about 35%.This use is novel to be energy-saving equipment efficiently, suitable for large-scale promotion.
