Abstract
The utility model relates to a multi-roll non-gate layered coal feeder. A casing is equipped with 2-3 fixed coal rollers which are parallel front and back, adjacent and rolling back in the same direction. These horizontal fixed coal rollers whose front is high and whose is back low are equipped with a tilting classifier whose lower side corresponds to front part of chain grate stoker. The top of the fixed coal rollers is equipped with a lower pipe opening of sliding coal pipe, whose front end is close to the top of the front fixed coal roller, and rear end to that of the adjustable coal roller. The adjustable coal roller arranged on the fixed coal roller is in parallel with them and rotating forwards, and both sides of it are separately equipped with rolling bearings and axles of bearing seats. A slot passes through the lateral plate of the casing, and the exposing part of slot out of the casing is equipped with a chain wheel which is connected with a driving device. The utility model digs coals smoothly with stable amounts, and it has broad coal ranges, lowered raw coals and easy popularization.
Description
Technical field the utility model relates to a kind of auxiliary equipment of coal-burning boiler.
Background technology is present, be located at the coal-burning boiler front and the feeder great majority supporting with it are decked coal-feeding machines, its structure is: be provided with 2-3 the root arranged side by side parallel adjacent and transfer roller of fixedly delivering coal that turn round together in front and back in the casing, be called for short fixed coal roller, the coal roller of these levels its former is higher slightly than the latter, below these fixed coal rollers, be provided with tilting sifter, corresponding with the traveling-grate stoker front portion below this sifter.Be provided with the coal sliding tube lower nozzle that links to each other with coal bunker on the top of fixed coal roller, this is positioned at the rectangle coal sliding tube mouth of casing, and its front end edge and front fixed coa top are close, and back end edge is corresponding with fixed coal roller top, back.Be provided with in parallel in coal sliding tube back end edge outside and can be along its coal flashboard that slides up and down, this coal flashboard outside be provided with tooth bar, and the gear corresponding with it is coaxial with worm gear, and the worm screw end corresponding with this worm gear is provided with the adjustment handwheel.The weak point of above-mentioned decked coal-feeding machine is:
1, it drops down onto on the fire grate in the coal seam thickness in control, produces certain resistance to dialling coal.
2, different coal and granularity are bigger to its control influence, make the coal seam thickness of dial-out inhomogeneous.
3, when coarse coal enters decked coal-feeding machine, the coal stuck phenomenon might appear dialling.
The summary of the invention the purpose of this utility model is to provide a kind of has certain motive force to dialling coal, makes the multiple roll of dialling the even and suitable all types of coals of the smooth and easy thickness of coal not have the flashboard decked coal-feeding machine.
The utility model mainly is to adopt an adjustable coal roller corresponding with existing fixed coal roller to replace the coal flashboard.This is adjustable, and the coal roller is located at above the fixed coal roller, and parallel with them.The top and the coal sliding tube lower nozzle back end edge of this is adjustable coal roller are approaching, so just force the coal in the coal sliding tube to come out from the space between fixed coal roller and the adjustable coal roller, play the effect of limiting the quantity of.The rotating shaft of above-mentioned adjustable coal roller has a cylindrical void that passes on the housing side wall, it is positioned at the outer part of casing and is provided with sprocket wheel, this sprocket wheel links to each other with existing transmission mechanism by chain, and make the rotation direction and the fixed coal roller direction of rotation of adjustable coal roller, promptly change forward, it and fixed coal roller acting in conjunction will push out through the coal tong of transfer roller, respectively establish a rolling bearing and the bearing block corresponding in the rotating shaft of above-mentioned adjustable coal roller both sides with it, be respectively equipped with sliding pair on one side that this diaxon bearing is corresponding with the casing interior plate and the casing interior plate, it can be one group but preferably two groups, and that the shape of sliding pair also can have is multiple, this sliding pair can make bearing move up and down along it, each links to each other with an end of a chain above-mentioned diaxon bearing again, and these two chains are respectively walked around one and will be separately fixed on two lower sprockets behind its upper sprocket wheel that upwards leads.This axle one end that is provided with two lower sprockets passes the casing through hole, is positioned at the outer part of casing and is provided with worm gear, and the worm screw end corresponding with this worm gear is provided with handwheel.
When coal seam thickness on the fire grate need increase, rotation hand wheel orders about worm and gear and rotates, and the lower sprocket coaxial with worm gear just also rotates thereupon, and the part of chain is wrapped on the sprocket wheel, make the chain contraction in length of tractive bearing block, so bearing block upwards lifts and along moving on the sliding pair.When coarse coal was clipped between adjustable coal roller and the fixed coal roller, because adjustable coal roller is to be subjected to the flexible location of chain tractive, thereby adjustable coal roller just floated, and treated that coarse coal transferred to back adjustable coal roller under the gravity effect to automatically reset.
The utility model has following advantage compared to existing technology: dial 1, that coal is smooth and easy, coal poking quantity is stable: owing to increase adjustable transfer roller, make and dial coal and not only do not have resistance but also also have thrust, coarse coal also can easily be transferred to, so just, make the coal amount of dial-out stable, the coal seam thickness that drops down onto on the fire grate is even.
2, adapt to the coal wide ranges, coal and coal particle size wide ranges that the feeder of this structure adapts to particularly can both adapt to wet coal, lump coal and the higher smalls of viscosity.
3, reduce canopy coal phenomenon: because the power that adjustable coal roller strap comes and the change of housing construction increase the quantity that enters the coal supply machine-made egg-shaped or honey-comb coal briquets to some extent, this just makes canopy coal chance reduce greatly, even wet coal, the higher smalls of viscosity is not prone to canopy coal phenomenon yet.
4, easily penetration and promotion: the utility model is the improvement of carrying out on the basis of existing equipment, and original equipment is changed not quite, easily implements.
