Agitation knife is evenly arranged with the wet coal stirring roller, is provided with shifting coal and turns rod below the wet coal stirring roller, the housing bottom
Portion is provided with the Screen assemblies of inclination, and the shifting coal turns between rod and Screen assemblies to be additionally provided with dials coal transfer roller, the screening group
The bottom of part is connected with web plate, and web plate is connected with the outlet of housing, and the conveyer belt or fire grate are located at Screen assemblies and web plate
Lower section.
It is preferred that, the open pore size of the web plate is more than the open pore size of Screen assemblies.
It is preferred that, the wet coal stirring roller turns between rod and is provided with coal leak preventing plate with coal is moved.
It is preferred that, the coal leak preventing plate is abrasion-resistant stee coal leak preventing plate.
It is preferred that, tilting coal flashboard is provided with above described group of coal transfer roller.
The invention has the beneficial effects as follows：
Wet coal or jelly coal become loose through the agitation of wet coal stirring roller, then coal turns rod and group coal transfer roller causes lower coal unobstructed equal by moving
Weighing apparatus, the wet coal being dispersed or jelly coal are sized component screening, and little particle falls directly into the conveyer belt of most bottom side or fire grate, bigger
Granule then conveyer belt or fire grate are fallen into by web plate, and larger granule is then discharged by outlet, will wet coal or to freeze coal uniform
It is distributed on conveyer belt or fire grate, conveniently wet coal or jelly coal is delivered to boiler, it is ensured that normal heat supply.Wherein, how wet coal agitation
Roller and criss-cross agitation knife improve agitation efficiency, and overall structure is simple, low cost.

Specific embodiment
With specific embodiment, technical solution of the present invention is described in further detail below in conjunction with the accompanying drawings, so that ability
The technical staff in domain can be better understood from the present invention and can be practiced, but illustrated embodiment is not as the limit to the present invention
Fixed.
Based on wet coal or freeze the coal distributing device of coal as shown in figure 1, a kind of, including lower coal bunker 1,1 bottom of lower coal bunker is even
Housing 11 is connected to, 11 bottom of the housing is provided with conveyer belt 10 or fire grate, if fire coal falls into fire grate, can directly enter pot
Stove burns, if fire coal falls into conveyer belt 10, can store standby etc..
The housing 11 is provided with wet coal stirring roller 5, Fig. 1 only one wet coal of setting in the lower position of lower coal bunker 1 and stirs
Dynamic roller 5, it is also possible to be arranged side by side 2-3, be evenly arranged with agitation knife on the wet coal stirring roller 5, each agitation knife is in cross
Shape.
5 lower section of the wet coal stirring roller is provided with shifting coal and turns rod 7, and 11 bottom of the housing is provided with the Screen assemblies of inclination
4, by taking Fig. 1 as an example, lower coal bunker 1 is arranged on the most upper right side of housing 11, then Screen assemblies 4 are arranged on the lower left side of housing 11.Institute
State shifting coal and turn to be additionally provided between rod 7 and Screen assemblies 4 and coal transfer roller 3 is dialled, general, move coal and turn rod 7 and dial the radius of coal transfer roller 3
Identical and radius more than wet coal stirring roller 5.
The bottom of the Screen assemblies 4 is connected with web plate 8, and web plate 8 is connected with the outlet 9 of housing 11, the conveyer belt 10
