Abstract

A kind of reverse spiral cloth device for coal of chain-grate boiler, including coal bunker, variable speed electric motors, particularly, it is characterized in that in coal bunker, be arranged with the first screw feeder and the second screw feeder in parallel, first screw conveyor shaft of the first screw feeder is equiped with spiral-poker sheet, the second screw conveyor shaft of the second screw feeder is equiped with spiral-poker sheet.The present invention is driven the first screw feeder to rotate by variable speed electric motors, particularly, and drive the second screw feeder to rotate, on each screw conveyor shaft two groups of reverse spiral-poker sheets being discharged to are made to rotate, make the fire coal in coal spout by centre to both sides, two lateral middle generations repeatedly transmit and mobile, the problem solving canopy coal, chute blockage, coal cinder and coal face obtain sufficient mixture, realizing uniform coal seam, make coal combustion obtain more abundant, effect of coal saving is good.

Description

A kind of reverse spiral cloth device for coal of chain-grate boiler
Technical field
The present invention relates to a kind of boiler drawing-in device, particularly relate to the reverse spiral cloth device for coal used in a kind of boiler coal bunker.
Background technology
Now widely used coal-burning boiler, when coal handling system is when entering coal to coal bunker, bunker coal is by from reentering coal bunker, because oarse-grained coal cinder natural packing is in coal bunker both sides, coal dust then concentrates on feed bin mid portion, causing fire grate air feed uneven, fire grate both sides are leaked out seriously, fire grate middle part then deficiency in draught, in boiler, fired coal combustion is insufficient, reduce the utilization rate of fuel, cause the serious waste of fuel, improve heat cost.
It addition, north of china in winter is cold, fire coal has produced when coal yard to freeze block, when entering coal bunker and coal spout place when coal, canopy coal and chute blockage problem easily occurs, directly affects the properly functioning of boiler.
Summary of the invention
The purpose of the present invention, is provide a kind of reverse spiral cloth device for coal of chain-grate boiler for problems of the prior art, can efficiently solve coal-fired block, fine coal skewness problem and the canopy coal occurred winter and chute blockage problem in coal bunker.
The technical scheme is that
A kind of reverse spiral cloth device for coal of chain type boiler, including the first screw feeder, the second screw feeder and variable speed electric motors, particularly, it is characterised in that:
First screw feeder and the second screw feeder are set in parallel in the coal bunker of chain-grate boiler, and the screw conveyor shaft of the first screw feeder is equiped with spiral-poker sheet, and the screw conveyor shaft of the second screw feeder is equiped with spiral-poker sheet;One end of first screw feeder is supported by the clutch shaft bearing in the clutch shaft bearing seat being installed on coal bunker sidewall, and the other end of the first screw feeder is supported by the second bearing in the second bearing block being installed on coal bunker right side wall;One end of second screw feeder is supported by the 3rd bearing in the 3rd bearing block being installed on coal bunker left side wall, and the other end of the second screw feeder is supported by the 4th bearing in the 4th bearing block being installed on coal bunker right side wall;
One end of first screw conveyor shaft of the first screw feeder is equiped with clutch shaft bearing end cap, and the other end of the first screw conveyor shaft of the first screw feeder is equiped with the first sprocket wheel by the output shaft connection of variable speed electric motors, particularly;
One end of second screw conveyor shaft of the second screw feeder is equiped with the second bearing (ball) cover;The other end of the second screw conveyor shaft of the second screw feeder is equiped with the second sprocket wheel, and the first sprocket wheel connects by chain is corresponding with the second sprocket wheel;
On first screw conveyor shaft of the first screw feeder, the spiral-poker sheet of installing is made up of first group of spiral-poker sheet and second group of spiral-poker sheet, and the hand of spiral of first group of spiral-poker sheet is contrary with the hand of spiral of second group of spiral-poker sheet;
On second screw conveyor shaft of the second screw feeder, the spiral-poker sheet of installing is made up of the 3rd group of spiral-poker sheet and the 4th group of spiral-poker sheet, and the hand of spiral of the 3rd group of spiral-poker sheet is contrary with the hand of spiral of the 4th group of spiral-poker sheet.
The first screw feeder is driven to rotate by variable speed electric motors, particularly, and drive the second screw feeder to rotate, on each screw conveyor shaft two groups of reverse spiral-poker sheets being discharged to are made to rotate, make the fire coal in coal spout by centre to both sides, two lateral middle generations repeatedly transmit and mobile, the problem solving canopy coal, chute blockage, coal cinder and coal face obtain sufficient mixture, realizing uniform coal seam, make coal combustion obtain more abundant, effect of coal saving is good.
Configuration power drive system, it is also possible to share drive system with traveling-grate stoker or stratified combustion equipment and run.It is suitable for all kinds of chain-grate boilers of various tonnages, different size.
