Continuous operation stability is strong, and energy saving and consumption reduction is effectual.
Description
Technical field
This utility model relates to coal-burning boiler apparatus field, especially a kind of horizontal chain grate coal-burning boiler even device for coal of coal supply feeding.
Background technology
At present, industry competition is more and more fierce, and country is more and more higher to the standard of energy-saving and emission-reduction, and enterprise safety operation, cost control consciousness are increasingly stronger, must seek safe operation, produces method stable, energy-saving and cost-reducing in coal stove uses.Traditional coal-burning chain-grate boiler is general the most merely uses " flashboard " to control coal seam thickness.Although, by constantly improving, such as: add " auger type " coal homogenizer, " double-roll type layering " coal homogenizer etc. in coal bunker.These even device for coal no doubt have its certain characteristic, but all need to consume certain electric energy and could drive；And investment, operating cost height, install and keep in repair relatively complicated.
Utility model content
The purpose of this utility model be provide to solve the deficiency of above-mentioned technology a kind of without consume electric energy, can be by finely dispersed for the coal charge horizontal chain grate coal-burning boiler even device for coal of coal supply feeding.
In order to achieve the above object, the horizontal chain grate coal-burning boiler even device for coal of coal supply feeding designed by this utility model, it includes feeding coal bunker, traveling-grate stoker and coal-burning boiler, arranging traveling-grate stoker between feeding coal bunker and coal-burning boiler, the coal charge in feeding coal bunker is delivered in coal-burning boiler by traveling-grate stoker；Traveling-grate stoker between feeding coal bunker and coal-burning boiler is provided above the coal flashboard for controlling every layer thickness, at feeding coal bunker, the upper end of the sidewall of coal flashboard side is provided with horizontal steel plate, horizontal steel plate is provided with some chains straight down, and chain is in same perpendicular, the lower end of chain is provided with coal homogenizer, described coal homogenizer includes cross bar and spaced grid bar, and the cross bar on coal homogenizer is connected with chain, and grid bar is straight down.
Technique scheme, coal charge in feeding coal bunker falls on traveling-grate stoker, its lack of homogeneity, and the coal charge of regional area is compacted, and is pressed into coal cinder etc., by the setting of the grid bar on coal homogenizer, can the coal cinder being compacted be dialled scattered, and on coal seam, transfer to several grooves, can effectively overcome the fine coal in centre position to concentrate, both sides bulky grain is many, burning time in the middle of play a Leng and play heap, insufficient, the shortcoming such as heat stability is poor, spatial load forecasting is difficult, equipment failure rate is high, coal consumption is high of burning.And during using, the deadweight of coal homogenizer is inserted inside coal seam, and can be loosened in coal seam in traveling-grate stoker course of conveying, it is not necessary to consume electric energy.
As optimization, described chain upper end is fixed on horizontal steel plate by nuts and bolt, and described bolt passes horizontal steel plate, and the lower end of bolt is fixing with chain to be connected, and the bolt above horizontal steel plate is provided with nut, and nut limits the height of bolt.The regulation to coal homogenizer height of adjusting by screw bolt and nut of this structure, thus realize it can be according to the particle diameter of bunker coal, coal seam thickness, coal type change and load variations, Field adjustment coal homogenizer inserts the coal seam degree of depth.Serviceability is more superior.
The horizontal chain grate coal-burning boiler even device for coal of coal supply feeding obtained by this utility model, cost of investment is low, simple in construction, and making, installation, maintenance are all very convenient, and has advantages such as need not consumption electrical energy drive.Operation stability is strong continuously, energy-saving and cost-reducing effectual.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of coal homogenizer of the present utility model.
Detailed description of the invention
The utility model will be further described to combine accompanying drawing below by embodiment.
Embodiment 1:
