Abstract
The invention discloses a feeding device for a chain grate boiler and a method thereof. The feeding device comprises a crusher, a sliding track, a hopper, bin partition plates, a bin stop ring, a coal gate, a counter, a controller, a slip ring motor, a dust fuel channel, a screen and a fan. The feeding device is suitable for fuel feeding of the chain grate boiler or a boiler integrating steam, an organic heat carrier and hot air. Fuel is crushed into lumps of a uniform size through the crusher and then falls into the screen; powdery fuel is blown into the dust fuel channel through the fan and then enters a first combustion room first to be combusted; the lumpy fuel falls into the bin, and being stopped by the bin partition plates and the bin stop ring, the fuel is evenly fed onto a grate. Meanwhile, the counter is placed on the bin stop ring, the number of bin partition plates which the fuel passes through is calculated to serve as an input quantity, and opening and closing of the coal gate are controlled through the controller so that the coal gate can be opened when the fuel on the grate reaches a certain quantity. The use method of the feeding device is simple, the combustion efficiency of the boiler is improved, and black smoke and dust are reduced.
Description
Technical field
The present invention relates to a kind of boiler drawing-in device, particularly relate to a kind of chain grate boiler drawing-in device and method thereof.
Background technology
For the energy-conserving and environment-protective responding country are called, advocate and use environmental protection to reclaim fuel as boiler oil.The usual particle of these fuel is uneven, there is powdered fuel and large patch fuel simultaneously, and conventional boiler feeding manner is gravity type coal method, namely directly drops in hopper by fuel, by fire grate conveying burning.This mode not science, the fuel in hopper is directly thrown on fire grate, and fuel pressure is closely knit, and closely knit fuel bed flowing resistance is very large, and restriction air enters fuel bed, causes anoxycausis, size fuel slug disorder distribution, reduces efficiency of combustion.
Meanwhile, when not controlling fuel and throwing in speed, easily cause imitation frosted glass bucket phenomenon, namely when boiler in use because of meet or the factor blowing out such as superpressure time, the fuel that fuel will ignite rapidly in hopper.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of chain grate boiler drawing-in device and method thereof are provided.
A kind of chain grate boiler drawing-in device comprises disintegrating machine, slideway, hopper, feed bin dividing plate, feed bin back-up ring, coal gate, counter, controller, slip electric motor, the first combustion chamber, dust fuel passage, screen cloth and blower fan; Disintegrating machine is placed in above slideway, slideway and hopper are bolted, and blower fan is contained on hopper, connect feed bin under hopper, feed bin is connected and composed by feed bin dividing plate and feed bin back-up ring, counter is contained on feed bin back-up ring, is connected with controller by electric wire, and controller is connected with slip electric motor, slip electric motor drives coal gate to complete lifting, be connected to dust fuel passage between first combustion chamber and hopper, screen cap is on blower fan, and blower fan is contained in hopper.
Described feed bin is separated by 6 feed bin dividing plates, is surrounded by feed bin back-up ring around.
The feeding method step of described chain grate boiler drawing-in device is as follows: the disintegrating machine above hopper is first by fuel crushing, fall on screen cloth and blower fan after baffle plate, powdered fuel is first blown into dust fuel passage by screen cloth and blower fan, directly enters the first combustion chambers burn; Granular fuel after fragmentation falls into feed bin, is discharged by fuel in the process that feed bin rotates; The counter at feed bin back-up ring place, by adding up the feed bin dividing plate number passed through, as input signal, controls slip electric motor by controller, promotes coal gate, controls fuel input amount.
Use the present invention, the efficient burning of fuel can be realized, the fuel of granular size inequality is first passed through crusher in crushing, again by screen cloth layering, can realize powdered fuel to burn in advance, patch fuel size is even, consumption appropriateness, avoid because of under Action of Gravity Field, the anoxycausis that fuel compacting causes and then reduction efficiency of combustion.Simultaneously, feed bin is connected with slip electric motor by rotating shaft, evenly in appropriate amount fuel is rendered on fire grate, by the counter at feed bin back-up ring place, using the feed bin baffle number passed through as input quantity, control the slip electric motor at coal gate runner place, coal gate is opened when fuel is rendered to a certain amount of, speed thrown in by effective control fuel, avoids imitation frosted glass bucket phenomenon.
