Description
Technical field
The invention belongs to thermal power plant coal spoil sorting arrangement technical field, be specifically related to thermal power plant's pair roller type coal and the elementary sorting equipment of gangue.
Background technology
Coal is as the main energy sources of China, and it plays extremely important effect in socio-economic development.The development and utilization of coal, both played huge impetus to social economy, also created significant impact to environment simultaneously.Gangue and coal bed gas are exactly the main discarded object produced in coal exploitation process, are considered as harmful substance and disastrous gas for a long time by coal industry.Gangue is the solid waste of discharging in the driving of coal, exploitation and washing process.China accumulates gangue and reaches more than 1,000,000,000 tons, also will discharge gangue 100,000,000 tons every year.In recent years, gangue is no longer only regarded as the maximum industrial solid castoff of a kind of quantity, and as a kind of resource, obtaining investigation and application widely in fields such as chemical industry, building materials, metallurgy, light industrys, utilization of coal gangue has become the emphasis of gangue comprehensive utilizating research.
Gangue is the rock that common consedimental organic compound and inorganic compound mix with coal in coalification course, usually in thin layer and in coal seam or top, coal seam, at the bottom of coal seam, being that mine that the quantity that produces in construction of coal mine and coal digging, dressing of coal by washing process is larger is solid-state dumps thing.Gangue is divided into claystone class, sandstone rock class, carbonate, pelite class by essential mineral content.By sources and end-state, gangue can be divided into digging gangue, coal separation spoil and natural spoil three major types.Gangue discharge capacity has larger difference according to the difference of coal seam conditions, mining conditions and washing process, and general digging gangue accounts for about 10% of raw coal output, and coal separation spoil accounts for 12% ~ 18% of feed coal amount.
Due to the trend of Multiple coal type and in poor quality, cause the actual coal that uses of power plant to be deteriorated, cause the pebble coal of pulverized coal preparation system significantly to become many further, and take normal coal out of.In pebble coal, the content of coal is too much, and this is a kind of situation of danger.
Summary of the invention
Object of the present invention will provide a kind of exactly and adopt telescopic elastic claw, the mixed material of coal and gangue is sorted, utilize the hardness of coal lower than gangue and the frangible feature of coal, telescopic elastic claw can be broken by coal, and the gangue that hardness is higher is carried out to the device that sorts.
The present invention is achieved through the following technical solutions:
Thermal power plant pair roller type coal and the elementary sorting equipment of gangue, comprise frame 1, be located at the chain conveyor 2 of frame 1 upper end, be located at the roller motor 3 of frame 1 upper end and the gearbox 4 that is connected with roller motor 3 and the pulverizing cavity 5 that is positioned at chain conveyor 2 upper end be positioned at pulverize cavity 5 upper end and with the feed hopper 6 pulverized cavity 5 and be connected, it is characterized in that: in described pulverizing cavity 5, be provided with the pair roller reducing mechanism be connected with gearbox 4; Described pair roller reducing mechanism is made up of action roller 7 and fixed roll 8; Described fixed roll 8 is provided with elastic claw device.
Described elastic claw device by roll shaft 81, be socketed in the backing roll 82 on roll shaft 81 and be located at roller circle 83 outside backing roll 82, one end is connected to spring 84 on backing roll 82 and one end is connected with spring 84 elastic claw 85, elastic claw 85 penetrates roller circle 83.
Described roller motor 3 side is provided with water inlet pipe 9 and is located at the shower nozzle 10 be connected with water inlet pipe 9 of chain conveyor 2 upper end.
Collecting chamber 11 is provided with inside described frame 1.
Compared with prior art, beneficial effect of the present invention is:
Pair roller reducing mechanism provided by the invention is made up of action roller 7 and fixed roll 8, fixed roll 8 is provided with by roll shaft 81, be socketed in the backing roll 82 on roll shaft 81, and the roller circle 83 be located at outside backing roll 82, one end is connected to the elastic claw device of the elastic claw 85 that spring 84 on backing roll 82 and one end are connected with spring 84, because elastic claw 85 penetrates roller circle 83, when elastic claw 85 carries out at pair roller the mixed material crushing coal cinder and gangue, the hardness of coal is far below the hardness of gangue, in the process that elastic claw 85 does relative motion with action roller 7 under the drive of roller motor 3, extruding elasticity is carried out broken when elastic claw 85 runs into coal time, and when running into gangue, elastic claw 85 is stretched in roller circle 83 by compression, gangue can not be broken and enter on chain conveyor 2 together with coal dust, when chain conveyor 2 is in the operation of lasting shake, coal dust can by falling into collecting chamber 11 in the gap of chain conveyor 2, and gangue can move on along with chain conveyor, finally undertaken rinsing well by the water of ejection in shower nozzle 10 and to be stored in addition afterwards, complete the elementary sorting work of coal and gangue.
Beneficial effect of the present invention is: structure is simple, practical, brings great convenience to user.
