Abstract

The utility model relates to an energy saving coal feeding hopper for a row-by-row layered homogeneous combustion boiler, belonging to the boiler auxiliary parts, which comprises a main body 1, a motor A, a speed reducer B, a mixer 2, a connecting rod 3, a screen piece 4, a spray water pipe 5, a row-by-row plate 6, a drive gear 7, a coal discharge drum 8, a coal amount control plate 9, a coal amount control plate spring 10, a locking nut 11, an adjusting plate12, a sliding plate 13, a coal feeding drum 14, a slag discharge hole 15, an observation hole 16, a water jacket 17, a coal outlet 18 and a grate chain wheel 19. The utility model is characterized in that the utility model adds the screen piece and a coal and water mixing device compared with the coal feeding device of the original row-by-row layered homogeneous combustion boiler, the flashboard type control coal feeding mode is changed to the sliding board control coal feeding mode, and the scattering type coal supply mode is adopted. The utility model thoroughly solves the problem of that the coal is blocked due to stoppage and the layers are nonuniform, and thereby is the most perfect coal feeding device for the row-by-row layered homogeneous combustion boiler.

Description

Layering divides the equal combusting boiler of line the energy-conservation coal bunker that adds

Technical field: the utility model relates to a kind of boiler energy-saving coal supply equipment, and it belongs to boiler applianee.

Background technology: the utility model is compared with prior art (2L96209791.8); original technology does not have screening plant to the coal that falls into coal bunker; and the coal that adds coal bunker is mixing up big fast spoil and foreign material; when they flow to coal outlet; controlled coal flashboard blocks; the cylinder of will delivering coal is stuck, causes parts to damage and shuts down.Lack in original technology and add water and agitating device, add the coal in the coal bunker, fine coal is placed in the middle, and particulate coal and lump coal then have been diverted to the coal bunker both sides, causes fine coal and lump coal skewness on the fire grate, adding behind the water local location or powdery coal and powdery coal sticks together, or powdery coal and particulate coal stick together, and drops on layering when sieving on the sheet in lines when them with the form that comes off naturally, and what have then is trapped on the sieve sheet, after in heaps, fall into again on the fire grate, seriously influenced layered effect.

Summary of the invention: the purpose of this utility model provides a kind of layering and divides the equal combusting boiler of line the energy-conservation coal bunker that adds, present technique has installed sieve sheet 4 additional adding the coal bunker porch, become flashboard type control coal and be slide type control coal, become the coal supply of nature separation-type and be the coal supply of spraying formula, to solve problem, make the obviously accurately layering of branch of coal on the fire grate because of the stuck cylinder of delivering coal of bulk spoil.

Further describe the utility model below in conjunction with accompanying drawing:

Fig. 1 is a front view of the present utility model

Fig. 2 is the front view of cylinder of producing coal

Fig. 3 is the front view of agitator

Fig. 4 is the front view of sieve sheet

Fig. 5 is a control coal restrictor bar front view

Fig. 6 is the front view of branch andante

The technical solution of the utility model is: open water spray switch → starter motor A → fire grate sprocket wheel 19, the cylinder 14 of delivering coal rotation at a high speed, decelerator B drives agitator 2 rotations and finishes mixing of coal water and stirring, moves up and down owing to the eccentric wheel drive link 3 on the agitator makes sieve sheet 4, cause big fast spoil and foreign material greater than coal outlet 18 to be discharged from outside the coal bunker from slag-drip opening 15, qualified powdery coal and particulate coal fall into discharges from coal outlet after coal bunker is stirred humidification.Fire grate sprocket wheel 19 driven gears 7 rotate synchronously, and order about cylinder 8 reverse sync of producing coal and rotate, coal above the coal amount control panel 9 is dialled down, drop on the slide plate 13, slip under continuing and deliver coal on the cylinder 14, the power of being used to of cylinder 14 of being delivered coal is shed on minute andante 6, the collision back is fallen in lines, because in the fine coal, bulky grain heavily falls soon, and it will drop on the orlop of fire grate so, and other small particles and pulverous coal will be sequentially arranged in, can obviously can accomplish loose orderly layering in lines again thereby reach, this is verified in test.

The beneficial effects of the utility model are: thoroughly eliminate in the coal process card coal machine halt trouble, really reach the purpose of the accurate layering of obvious branch.

Description of drawings: running of the present utility model has two power.The fire grate sprocket wheel of one source and chain furnace and travelling gear 7 run-in synchronisms and driving are produced coal and are rolled the running of 8 reverse sync, and the coal of coal outlet is dialled down, are slipped to slide plate 13, fall to sliding on the cylinder 14 of delivering coal again, and quilt is shed branch andante 6 whereabouts fire grates.Rotate the main shaft of adjustable plate 12, move or move down on the coal amount control panel 9, thereby make the coal outlet increasing or dwindle the control coal-supplying amount.It two derives from motor A, and motor A drives the cylinder 14 of delivering coal, when running up, also drive decelerator B, agitator 2 runnings, the connecting rod 3 that connects agitator drives sieve sheet 4 and moves up and down under eccentric effect, thereby mixing of coal water and stirring screening are finished synchronously.

Accompanying drawing 2 expression is produced coal, and cylinder 8 is vertically equidistant to stud with round bars, utilizes the longitudinal groove that forms that the coal at coal outlet place is dialled down.

Be equipped with two on the accompanying drawing 3 expression agitators 2 and stir bar, stir bar 1 dextrorotation to the right.Stir bar 2 derotation left.The fine coal that its purpose will add in the coal bunker when stirring evenly mixes with lump coal, and divides equally to the coal bunker both sides.

Accompanying drawing 4 expression sieve bobbins are in the A-A position, and the sieve sheet is up and down and sieves.

Lower flashboard 1 press in accompanying drawing 5 expression, and rocker die 3 is lifted, pull restrictor bar 2 adjustable plate 12 is moved down or on move, thereby increasing or dwindle coal outlet, to finish the control coal-supplying amount.

Accompanying drawing 6 expressions divide the andante back that water jacket is housed.
