Description
Technical field:
The utility model relates to the improved technical field of boiler plant, particularly a kind of boiler stratified combustion coal supply device.
Background technology:
Energy savings, the protection environment is a fundamental state policy of China.At present, the enterprise of China has entered high speed development epoch, the energy-saving and emission-reduction of enterprise, and environmental protection consciousness is constantly strengthened.And governments at all levels all give top priority administering atmosphere and environmental pollution in the work of optimizing the environment for investment.At present, China has 1,200,000 burning boilers to be distributed in about more than 50 ten thousand boiler rooms in all parts of the country approximately, and, these burning boiler major parts are still being used traditional stove and accessory and combustion method, these boilers can't be accomplished the as far as possible fully burning of fuel, therefore, have given off a large amount of flue dust, these flue dust enter into atmosphere, have caused the aggravation of greenhouse effects; In addition, the particle in the flue dust causes the fog occurrence probability to increase greatly in atmosphere, and these do not have clean-burning particle to be regarded waste discharge, have caused the waste of resource.So, boiler is transformed, to improve its thermal efficiency, removing and reduction flue dust and discharge of harmful gases concentration are imperative.If want to improve the thermal efficiency of boiler, lower dust emission, allowing coal fully burn as much as possible is one of solution.
In view of above-mentioned technological deficiency, it is a kind of simple in structure, easy to use to press for appearance, can make fuel as much as possible fully burning in boiler, lowers a kind of boiler stratified combustion coal supply device of boiler dust discharging.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, provides a kind of simple in structure, easy to use, can make fuel as much as possible fully burning in boiler, lowers a kind of boiler stratified combustion coal supply device of boiler dust discharging.
To achieve these goals, the utility model provides a kind of boiler stratified combustion coal supply device, comprise coal bunker and favourable turn, wherein, described coal bunker top is provided with coal bunker, and described coal bunker inside is provided with the spinosity cylinder, described thorn cylinder is positioned at the below of described coal bunker, the below of described thorn cylinder is provided with lower baffle plate, is solidly connected between described lower baffle plate and the described coal bunker, and described coal bunker and described coal bunker are solidly connected.
The below of described lower baffle plate is provided with the coal breakage cylinder, described coal breakage cylinder is provided with chain, be connected by described chain between described coal breakage cylinder and the described favourable turn, described coal bunker is provided with transmitting gear, is connected with a joggle between described thorn cylinder and the described transmitting gear.
Further be provided with wide-meshed screen between described coal bunker and the described coal bunker, plug together between described wide-meshed screen and the described coal bunker and be connected.
The oblique below of described coal breakage cylinder is provided with composite screen, and described composite screen is provided with fine screen mesh, and described composite screen bottom is provided with vibration rod, is solidly connected between described vibration rod and the described composite screen.
The below of described transmitting gear is provided with the coal flashboard, plugs together between described coal flashboard and the described coal bunker to be connected.
Advantage of the present utility model is, and is simple in structure, easy to use, can make fuel as much as possible fully burning in boiler, lowers the boiler dust discharging.Specific as follows:
The utility model is when boiler advances coal, and coal enters from coal bunker, and coarse coal or stone are chosen in the wide-meshed screen elder generation scalping below coal bunker one time, and it is insufficient to avoid burning.After coal fell from wide-meshed screen, through the rotation of thorn cylinder, a little bigger a little coal was blended into fritter or coal dust, small coal or coal dust or on lower baffle plate, slide on the coal breakage cylinder from lower baffle plate, falling on the composite screen from the coal breakage cylinder, behind the fine screen mesh on the composite screen, fall in boiler grate, the burner hearth, burn, the ature of coal on composite screen shakes through vibrating head, can be better evenly unrestrained, be convenient to ature of coal and as much as possible fully burn.So coal falls into through several secondary clearings, because of its gravity inequality, coal can fall in layering, can make burning abundant as much as possible, lowers dust emission, improves the thermal efficiency.
