Abstract

The utility model relates to an oblique vibration type layered coal conveying machine. The utility model comprises a machine body of the coal conveying machine, a coal broadcasting roller, a sieving device, a driving device, a fire grate motor, etc. The utility model is characterized in that triangular roller teeth are arranged on the surface of the coal broadcasting roller, a coal plate with a vibrating plate is slantwise arranged below the coal broadcasting roller, the coal plate is assembled on the machine body of the coal conveying machine through a guiding device, and the lower part of the coal plate contacts a cam which rotates. The utility model has the advantages of forceful coal broadcast, high work efficiency, good layering effect of block powder, high combustion efficiency, no phenomena of coal leakage and the friction of the coal broadcasting roller, and safe operation.

Description

Tilt and vibration formula layering coal conveyor

The utility model belongs to a kind of coal conveyor tool, particularly a kind of tilt and vibration formula layering coal conveyor.

At present, some industrial furnaces utilize layering coal handling plant defeated coal on fire grate in order to improve coal-fired combustion efficiency, and the coal on the fire grate is distributed by layer, promptly are followed successively by coarse coal, medium sized coal, nut coal, coal face from bottom to up, make coal-fired energy economic combustion.Develop a kind of coal sowing roller type coal conveyor in recent years, it is smoother to broadcast coal roller surface, and it is not strong to broadcast the coal dynamics; Leak the coal problem between roller in order to solve simultaneously; holder coal plate is arranged in the bottom, but time of run is long slightly, coal dust increases on the holder coal plate; if coal is relatively moister; or with the humid air that coal dust on the holder coal plate is formed is hard fixing block, contact with the round bottom of coal sowing roller arc tighter, the generation friction force; increase motor load; all can produce to a certain degree infringement to electric machine main shaft and reductor, a severe patient even roller phenomenon, the shutdown maintenance of having to take place to embrace.

The purpose of this utility model provides a kind of tilt and vibration formula layering coal conveyor, and it is strong to broadcast coal, high efficiency, and piece powder layered effect is good, and the combustion efficiency height does not have the coal of leakage and broadcasts coal roller friction phenomenon, and is safe and reliable to operation.

The purpose of this utility model is achieved in that it comprises the coal conveyor body, broadcasts coal roller, sifter, driving device and fire grate etc., and its technical scheme main points are: broadcast triangle roller tooth is set on the coal roller surface; Be obliquely installed the coal plate of being with oscillating plate below broadcasting the coal roller, the coal plate is assembled on the coal conveyor body by guide piece, the cam that the contact of coal plate bottom is rotated.

Principle of work: when fire grate rotates, broadcast rotation of coal roller and camshaft rotation by the driving device drive, broadcasting the fire coal that triangle roller tooth on the coal roller will drop in the coal conveyor broadcasts on the tilt and vibration coal plate of below, bevelled coal plate is under the rotating cam effect, failure of oscillation is not moving up and down, the coal cinder coal dust hangs on sifter after producing separation phenomenon again, and sifter is further with the fire coal screening, successively by bulk, middle piece, fritter, be that coal dust is delivered on the fire grate at last, forming bulk the most following, is middle piece then, is fritter above again, is the cloth coaly attitude of coal dust, neither leak coal, permeability to air is good again, has improved combustion efficiency.

The utility model and existing product relatively have following advantage:

1, owing to is provided with tilt and vibration formula coal plate, make broadcast fire coal that the coal roller sows by vibration with the fine separation of piece powder, and can sow into the uniform in-plane state, drop on the sifter, play the effect of pre-layering, the efficient and the quality of the defeated coal of the further layering of sifter are significantly improved, thereby have played the effect that improves combustion efficiency.

2, removed to broadcast between the coal roller to leak to asking coal dust on the coal plate to pile up friction and broadcast some problems that the coal roller strap comes, equipment operation is safe and reliable, trouble free.

3, be provided with triangle roller tooth owing to broadcast the coal roller, it is strong to broadcast the coal dynamics, high efficiency.

4, the multilayer sieve on the sifter makes the coal-fired level of screening good, can avoid gathering coal and coarse coal spoil to fall to smashing the problem of sifter simultaneously.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is the right elevation of Fig. 1.

Fig. 3 is the left view of Fig. 1.

Fig. 4 is the scheme of installation of cam and coal plate.

See Fig. 1-4, concrete structure is as follows: the top of coal conveyor body 4 is coal feeding hole, and its middle part is rotated two of connections by roll shaft 6 and broadcast coal roller 3, broadcasts coal roller 3 surfaces and goes up the uniform leg-of-mutton roller teeth 5 that are provided with.Two broadcast coal roller 3 below be obliquely installed coal plate 7, coal plate 7 connects tilt and vibration plates 12, mounting structure is: affixed orienting sleeve 17 on the periphery of coal plate 7, fixed guide post 16 on coal conveyor side plate 11, the orienting sleeve slip cap is contained on the guidepost 16.Connect between two roll shafts 6 and between roll shaft and the driving device of fire grate 14 by the end; Rotate connection cam 9 by camshaft 10 below coal plate 7, camshaft 10 is by driving device 15 and roll shaft 6 driving coupling.The affixed force-bearing base 8 in the bottom of coal plate 7, force-bearing base 8 contacts with cam 9 surfaces, cam rotation, up-down vibration promptly takes place in the coal plate.Tilt and vibration plate 12 tiltedly below assembling have the sifter 2 of four layers of screen cloth, the sieve aperture of each layer is descending from top to bottom, realizes coal-fired piece powder layering.The utility model shown in Fig. 1 is assembled in body of heater face arch 1 bottom, and the below of sifter 2 is fire grates 13 of operation.
