Abstract
The utility model discloses a coal screening system which comprises a drum screen. A coal slag outlet and a coal outlet are arranged on the drum screen, a spiral screen is arranged at the coal outlet, a coal discharge port is arranged on the lower portion of the spiral screen, a rotating coal handling belt is arranged below the coal discharge port, and a coal slag conveying belt is arranged below the coal slag outlet. The coal screening system screens coal in a mode of serial arrangement of the drum screen and the spiral screen, screen meshes cannot be blocked during clammy coal handling, screening efficiency is high, calorific value of the coal is increased, and coal quality is improved obviously. By the aid of the spiral screen, speeds of tangential directions of two sides of a spiral shaft of the spiral screen are opposite, and the coal cannot be broken easily during screening, so that carbon coal in the coal is easy to sort, and screened coal fragments are few. Advance speed of coal screening is high, and handling capacity is large and can reach 250 ton per hour.
Description
Technical field
The utility model relates to a kind of coal screening system.
Background technology
The most colliery when coal is screened, is all to adopt simple mesh screen to carry out disposable screening, and the problem of existence is that the coal fragment that sifts out is many, impurity is large, and the coal volatile matter is high, and caloric value is low, Coal Quality is poor, in addition, and the problem that also exists wet sticking coal to screen.The coal that existing screening technique filters out is sold and has been subject to certain influence due to of poor quality.For improving Coal Quality, improve the coal indices, must improve existing screening system.
The utility model content
The purpose of this utility model is to provide a kind of coal screening system.
In order to realize above purpose, the utility model adopts following technical scheme: a kind of coal screening system, comprise rotary screen, be provided with cinder outlet and export of coal on described rotary screen, described export of coal place is provided with spiral screen, the bottom of described spiral screen is provided with coal outlet, and the below of described coal outlet is provided with rotation fortune coal belt, and the below of described cinder outlet is provided with the belt of mucking haulage.
Further, described spiral screen is SL-U
125/1.5-A type spiral screen.
The mode that the coal screening system that the utility model provides adopts rotary screen and spiral screen string to establish is screened coal, processes wet sticking coal and can not stop up sieve aperture, and screening efficiency is high, has improved the caloric value of screening coal, and Coal Quality is obviously improved; Adopt spiral screen, because the speed of the tangential direction on the helical axis both sides of spiral screen is opposite, coal is difficult for producing broken in screening process, and the coal fragment that therefore sifts out is few, and the carbon coal in coal easily sorts; The material screening fltting speed is fast, and treating capacity is large, per hour can reach 250 tons.The coal screening system that the utility model provides can solve wet sticking coal, coal slag many etc. cause can't the sizing screening problem.
The coal screening system that adopts the utility model to provide, the ature of coal indices that screening obtains coal all is significantly improved, for Business survival is laid a good foundation, for coal sales has been opened road, simultaneously, along with the raising of heating value of coal, the economic benefit of enterprise also is significantly improved.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Embodiment
As shown in Figure 1, a kind of coal screening system, comprise rotary screen 7, be provided with cinder outlet 6 and export of coal 1 on rotary screen 7, export of coal 1 place is provided with spiral screen 2, the bottom of spiral screen 2 is provided with coal outlet 3, and the below of coal outlet 3 is provided with rotation fortune coal belt 4, and the below of cinder outlet 6 is provided with the belt 5 of mucking haulage.Spiral screen 2 is SL-U
125/1.5-A type spiral screen.
The mode that the coal screening system that the present embodiment provides adopts rotary screen 7 and spiral screen 2 strings to establish is screened coal, processes wet sticking coal and can not stop up sieve aperture, and screening efficiency is high, has improved the caloric value of screening coal, and Coal Quality is obviously improved; Adopt spiral screen, because the speed of the tangential direction on the helical axis both sides of spiral screen is opposite, coal is difficult for producing broken in screening process, therefore the carbon coal in coal is easily sorted, and the coal fragment that sifts out is few; The material screening fltting speed is fast, and treating capacity is large, per hour can reach 250 tons.The coal screening system that the present embodiment provides can solve wet sticking coal, coal slag many etc. cause can't the sizing screening problem.The coal screening system that adopts the present embodiment to provide, the ature of coal indices that screening obtains coal all is significantly improved, for Business survival is laid a good foundation, for coal sales has been opened road, simultaneously, along with the raising of heating value of coal, the economic benefit of enterprise also is significantly improved.
