Abstract
A uniform coal feeding device for a chain boiler relates to a boiler and comprises a barrel-shaped body. A rotatable spindle is disposed in the body, two ends of the spindle are connected onto a side wall of the body, a pusher dog is arranged on a columnar body of the spindle, and a motor is fixed on the outside of the body, is connected with the spindle via a gear box and a transmission mechanism and provides power for rotation of the spindle. The root of the pusher dog is perpendicular to a columnar surface of the spindle, the front end of the pusher dog is bent by 90 degrees, and the total pusher dog is '7'-shaped. The uniform coal feeding device is simple in structure and reliable in operation, can uniformly stir dry and wet coal and coal briquettes in a coal bin, achieves the effect of adjusting property and humidity of fire coal, can improve burning effect of the fire coal, prevents 'bland bands' generated on a fire grate surface, increases production efficiency of the total chain boiler, and saves energy.
Description
Technical field
The utility model relates to a kind of boiler plant, particularly a kind of coal feeder that coal in the chain-grate boiler coal bunker is stirred.
Background technology
Chain-grate boiler is the higher a kind of grate furnace of mechanization degree, gains the name because of its fire grate is similar to the chain-type crawler belt, is to use more a kind of type of furnace in the Industrial Boiler, in the 10-65t/h intermediate size, even in the low capacity boiler of 1-2t/h employing is arranged all.Chain-grate boiler is to raise the formula stove before a kind of, and the burning of coal process is finished in moving, its stable combustion condition, and the thermal efficiency is higher, and operation is convenient, and labour intensity is low, and smoke dust discharge concentration is lower.It belongs to the single face ignition mode, and fuel does not have self disturbance during operation, along fire grate length direction fuel bed tangible subregion is arranged.Because ignition condition is bad, poke fire and necessary manually-operated, so it is unsuitable for the coal that branch is very big, ash content is many again, coking capacity is strong of heating up water.
During work, behind coal-fired the process defeated device for coal and coal bunker of chain-grate boiler, fall into grate surface, be admitted to the fire bed of burning burning.In the program of this defeated coal coal supply, defeated device for coal adopts usually is belt conveyor or buries the link plate conveyer, when coal-fired discharge port from defeated device for coal falls into coal bunker, can pile up, tumble by nature, form the massif shape, and piece foam inequality also can be because of accumulation causes middle coal density big, and the density of both sides is little.Like this, when the fire coal in the coal bunker is fallen on the grate surface, also can be inhomogeneous accordingly, the coal that shows as the fire grate both sides is for block, and this part coal-fired flowing resistance is little, and combustion position is all right; Fall into the middle coal of grate surface and then be the foam shape, this coal density is big, flowing resistance is big, and it is just bad to blaze up.So just have one in the middle of the grate surface because of insufficient " black-tape " that produces that burn.Just highlighted the inherent shortcoming of aforesaid this type of boiler more, caused grate firing unbalanced, not steady, influenced boiler design technical indicator and economic benefit, also the serious waste energy.
The utility model content
The purpose of this utility model is the even coal feeder that a kind of simple in structure, even coal of invention is effective, be used for chain-grate boiler, the fire coal in the coal bunker can be mixed, and the massif shape of piling up do not occur.
This coal feeder includes body, and body is a tubular, is provided with rotating main shaft in the body, and the two ends of main shaft are connected on the sidewall of body, and the cylinder of main shaft is provided with pusher dog; This external motor that is fixed with, motor is connected main shaft by gearbox with transmission mechanism, provides power to main axis rotation.
Described pusher dog to be shaped as root vertical with the main shaft cylinder, crooked 90 ° of front end, whole pusher dog is " 7 " font.
The described main shaft that has pusher dog is provided with 2 in body, each all is connected with transmission mechanism, can rotate.By the variation of transmission mechanism, as varying in size of travelling gear, the velocity of rotation of two main shafts can be different, and rotation direction also can be different.
Described pusher dog is provided with a plurality of on each main shaft, as 2, does not need to be symmetrical arranged.
The even coal feeder of chain-grate boiler of the present utility model, simple in structure, reliable, can be placed in the coal bunker not, utilize main axis rotation to drive pusher dog, with doing in the coal bunker, wet coal and piece, smear and stir, reach the effect of regulating coal-fired proterties and humidity, can improve coal-fired combustion efficiency, prevent to occur on the grate surface " black-tape " phenomenon, improve the production efficiency of whole chain-grate boiler, energy savings.
Description of drawings
Fig. 1, structure chart of the present utility model.
Fig. 2, the lateral plan of body and main shaft.
The specific embodiment
As Fig. 1, body 1 is the tubular of rectangle, and the sidewall of symmetry is provided with main shaft 2, and the cylinder of main shaft 2 is provided with pusher dog 21, and two pusher dogs 21 are set on each main shaft, and two main shafts 2 be arranged in parallel in the body 1.Main shaft 2 is connected to the transmission mechanism 5 of the outside of body 1, and transmission mechanism 5 is connected with gearbox 3, and gearbox 3 connects motor 4, and motor 4 can drive main shaft 2 rotations.
In the time of work, the direction of rotation of two main shafts 2 in the present embodiment is rotation relatively.This device is installed on coal bunker middle part, and the front conveying device is carried the fire coal of coming, enter coal bunker the time, pusher dog 21 by coal feeder of the present utility model is pushed aside, dials even, can not produce nature and pile up, and piece, foam coal mix, the coal of doing, wet also effectively mixes, and helps being sent to the fire grate burning.
Above embodiment is described only to be an implementation of the present utility model; the variation of main shaft quantity and pusher dog shape, quantity all be those skilled in the art can expect easily; also should belong to protection domain of the present utility model, and the utility model is equally applicable to the body of non-rectangle.
