Abstract
A coal feeding device for a chain fire grate boiler combusting moist coal is provided, the upper part of the shell of the device is a coal feeding bucket, one side of the coal feeding bucket is provided with an outlet regulator of the coal feeding bucket and an adjustable gate, a paddling shaft is arranged in the coal feeding bucket, a circumference of the paddling shaft is uniformly distributed with paddle teeth, gaps between top parts of the paddle teeth and an inner wall of the coal feeding bucket are 2-10mm, a coal-distributing roller is positioned under the outlet of the coal feeding bucket, a baffle and a coal loose screen are respectively positioned at two sides under the coal-distributing roller, a driving sprocket on a driving wheel of the fire grate driven by a motor drives an intermediate sprocket and the coal-distributing roller which is connected with the intermediate sprocket through chains, the intermediate sprocket drives a driven sprocket and the paddling shaft which is connected with the driven sprocket through chains. The utility model especially combusts moist coals with over 15 percent water content, so coals can be combusted more sufficiently, thereby further improving a boiler output; and combustion effect is same as coal water slurry, but combustion cost is one third to a half of the coal water slurry.
Description
Technical field
The chain type fire grate coal feeder of boiler tool device that the wet coal of the coal supply mechanical device of using on a kind of coal-burning boiler, especially burning is used, ICL is F23K/08.
Background technology
Existing various chain type fire grate coal supply apparatus for boiler only is adapted to the dry coal that burns, and the water content of can not burning is greater than 15% wet coal.The jam coal feeding bucket that lumps easily exports because wet coal is subjected to the influence of the hot-air that boiler furnace overflows when entering coal bunker, need the people to strike through rod iron bucket commonly used, iron hammer, waste time and energy, and poor effect often, have a strong impact on the operate as normal of boiler, so people avoid adding wet coal as far as possible in coal feeding bucket.
Summary of the invention
The purpose of this utility model is to overcome traditional coal idea of only dryouting, a kind of chain type fire grate boiler combustion coal feeder that wet coal is used is provided, accomplish the special combustion water content greater than 15% wet coal, hydrogen, oxonium ion that water is at high temperature produced promote burning, improve efficiency of combustion.
Housing of the present utility model top is a coal feeding bucket, coal feeding bucket one side is equipped with coal feeding bucket outlet regulating device and adjustable flashboard, the paddling axle is housed in the coal feeding bucket, be evenly distributed with shave tooth on the paddling axle periphery, gap between shave tooth top and the coal feeding bucket inwall is the 2--10 millimeter, cloth coal cylinder is positioned at coal feeding bucket outlet below, and baffle plate, loose screen lay respectively at both sides, cloth coal cylinder below.By the cloth coal cylinder that the drive sprocket on the fire grate driving wheel of driven by motor drives intermediate chain wheel and links with it through chain, the paddling axle that intermediate chain wheel drives driven sprocket and links with it through chain.
Operation principle is as follows: drive behind the electrical power driving wheel and on the drive sprocket rotation, driving wheel promotes fire grate and moves forward, drive sprocket drives intermediate chain wheel and the rotation of cloth coal cylinder through chain, intermediate chain wheel drives paddling axle fast rotational through chain again, and the coal that constantly will wet of the shave tooth on the paddling axle is drawn and dropped on the cloth coal cylinder.Along with the slow rotation of cloth coal cylinder, wet coal is ground warp baffle plate or directly fall on the loose screen in layer.The effect of pine screen is to catch wet coal, slows down the speed that wet coal falls, and wet coal is slowly slid down along loose screen, thereby relatively more loose being evenly distributed on the fire grate of reach enters the burner hearth internal combustion.
Compared with prior art, the utility model has following characteristics:
1, coal combustion is more abundant, has further improved boiler output.
Because water content reaches more than 15% in the coal, at high temperature the hydroxyl ion that produces promotes burning, has complied with the reason that bituminous coal catches fire, coking is burnt again, and therefore burning is more abundant, and boiler output is bigger.
2, reduced the burning cost.
Combustion efficiency of the present utility model is the same with water-coal-slurry, and the burning cost has only 1/3 to 1/2 of water-coal-slurry.
Description of drawings
Fig. 1 is the coal feeder structural representation that the wet coal of chain type fire grate boiler combustion is used.
Fig. 2 is the A-A cross-sectional view of cloth coal drum segment.
The specific embodiment
As shown in Figure 1, housing 1 top is a coal feeding bucket 2, coal feeding bucket 2 one sides are equipped with coal feeding bucket outlet regulating device 10 and adjustable flashboard 11, paddling axle 4 is housed in the coal feeding bucket 2, be evenly distributed with shave tooth 5 on paddling axle 4 peripheries, gap between shave tooth 5 tops and coal feeding bucket 2 inwalls is the 2-10 millimeter, cloth coal cylinder 6 is positioned at coal feeding bucket 2 outlet belows, baffle plate 8, pine screen 9 lays respectively at into both sides, coal cylinder 6 below, by the cloth coal cylinder 6 that the drive sprocket 14 on the driving wheel of the fire grate (13) of driven by motor drives intermediate chain wheels 7 and links with it through chain 12, intermediate chain wheel 7 drives driven sprockets 3 through chain 15 and reaches the paddling axle 4 that links with it.Shave tooth 5 on the paddling axle 4 can be tapered or triangular form blade.
Because foreign material such as stone, wood are arranged unavoidably in the coal, these foreign material might block cloth coal cylinder and make it and can not rotate, the accident that causes motor to damage, so present embodiment is provided with clutch, suffers damage with the prevention motor.
As shown in Figure 2, between cloth coal cylinder 6 and its intermediate chain wheel 7 of drive clutch 16 is housed.When cloth coal cylinder blocks when motionless for some reason, the right clutch-plate of clutch 16 under the extruding of left clutch-plate automatically the compression spring break away from left clutch-plate toward moving right, motor can only drive intermediate chain wheels 7 idle running through drive sprocket 14, thus the protection motor is without prejudice.
