Description
Technical field
The invention belongs to thermal power plant coal spoil sorting arrangement technical field, and in particular to thermal power plant pair roller type coal and bastard coal
Stone primary sorting equipment.
Background technology
Coal as China main energy sources, it plays extremely important effect in socio-economic development.Coal
Development and utilization, both plays huge impetus to social economy, while also generating significant impact to environment.Gangue and
Coal bed gas is exactly the main discarded object of generation during coal exploitation, is considered as harmful substance and disaster by coal industry for a long time
Property gas.Gangue be coal driving, exploitation and washing process in discharge solid waste.China accumulates gangue up to 1,000,000,000
More than ton, 100,000,000 tons of gangue will be also discharged every year.In recent years, gangue was no longer only taken as a kind of maximum work of quantity
Industry solid waste, and as a kind of resource, obtained extensive research in fields such as chemical industry, building materials, metallurgy, light industrys and answered
With utilization of coal gangue has turned into the emphasis of gangue comprehensive utilizating research.
Gangue is that organic compound and inorganic compound with coal co-deposition in coalification course are mixed
Rock, generally in thin layer and in coal seam or coal seam top, coal seam bottom, be in construction of coal mine and coal digging, dressing of coal by washing process
The mine solid-state that the quantity of middle generation is larger dumps thing.Gangue is divided into claystone class, sandstone rock class, carbon by essential mineral content
Barbiturates, pelite class.By sources and end-state, can be divided into digging gangue, coal separation spoil and natural spoil three big for gangue
Class.Gangue discharge capacity has larger difference according to the difference of coal seam conditions, mining conditions and washing process, and general digging gangue is accounted for
10% or so of raw coal output, coal separation spoil accounts for the 12%~18% of feed coal amount.
Due to Multiple coal type and the trend of in poor quality, cause the actual coal that uses of power plant to be deteriorated, further result in powder processed
The pebble coal of system significantly becomes many, and takes normal coal out of.The content of coal is excessive in pebble coal, and this is a kind of dangerous situation.
The content of the invention
It is a kind of using telescopic elastic claw present invention aim to provide, the mixed material of coal and gangue is divided
Pick, using coal hardness be less than gangue and frangible coal the characteristics of, telescopic elastic claw can crush coal, and higher for hardness
The device that gangue is sorted.
The present invention is achieved through the following technical solutions：
Thermal power plant pair roller type coal and gangue primary sorting equipment, including frame 1, be located at the upper end of frame 1 chain type it is defeated
Send device 2, the gearbox 4 that is located at the roller motor 3 of the upper end of frame 1 and is connected with roller motor 3 and positioned at chain conveying
The crushing cavity 5 of the upper end of device 2 and positioned at crush the upper end of cavity 5 and with crush the feed hopper 6 that is connected of cavity 5, its feature exists
In：Be provided with described crushing cavity 5 be connected with gearbox 4 to roller reducing mechanism；It is described to roller reducing mechanism by moving
Roller 7 and fixed roll 8 are constituted；Described fixed roll 8 is provided with elastic claw device.
Described elastic claw device is by roll shaft 81, the support roller being socketed on roll shaft 81 82 and is located at the outside of support roller 82
The spring 84 that is connected in support roller 82 of roller circle 83, one end and the elastic claw 85 that is connected with spring 84 of one end, elastic claw 85 penetrates
Roller circle 83.
The described side of roller motor 3 be provided with water inlet pipe 9 and be located at the upper end of chain conveyor 2 with the phase of water inlet pipe 9
The shower nozzle 10 of connection.
The described inner side of frame 1 is provided with collecting chamber 11.
Compared with prior art, the beneficial effects of the present invention are：
What the present invention was provided is made up of to roller reducing mechanism dynamic roller 7 and fixed roll 8, is provided with fixed roll 8 by roll shaft 81, socket
Support roller 82 on roll shaft 81 and it is located at the spring that the roller circle 83, one end in the outside of support roller 82 is connected in support roller 82
84 and the elastic claw device of elastic claw 85 that is connected with spring 84 of one end, because elastic claw 85 penetrates roller circle 83, when elastic claw 85 is to roller
When crush the mixed material of coal cinder and gangue, the hardness of the hardness far below gangue of coal, elastic claw 85 is in roller motor 3
Drive under done relative motion with dynamic roller 7 during, it is broken to carry out extruding elasticity when elastic claw 85 runs into coal, and when meeting
During to gangue, elastic claw 85 is stretched into roller circle 83 by compression, and gangue will not be broken and enter chain conveying together with coal dust
On device 2, when in operation of the chain conveyor 2 in lasting shake, coal dust can be by falling into the gap of chain conveyor 2
In collecting chamber 11, and gangue can move on chain conveyor, and finally the water by ejection in shower nozzle 10 is rinsed
Stored in addition after clean, completed the primary sorting work of coal and gangue.
Of the invention has the beneficial effect that：Simple structure, it is practical, brought great convenience to user.
