Abstract
The invention provides a combined type dry method vertical coal separator which comprises a cylindrical shell and a cylindrical pillar which is coaxial with the cylindrical shell and arranged in the cylindrical shell. The outer wall of the cylindrical pillar is provided with multiple layers of step-shaped rotating chutes from top to bottom, and the outer end faces of the step-shaped rotating chutes are fixed to the inner wall of the cylindrical shell. The top of the cylindrical pillar is sealed, a sealed end is formed, and the top face of the sealed end is provided with an electromagnetic vibrator. The bottom of the cylindrical shell is provided with a fine coal discharging opening and a gangue discharging opening which are opposite to the bottom end of the bottom step-shaped rotating chute arranged at the bottommost layer. Through the multi-stage step-shaped rotating chutes, raw coal is subjected to multi-stage separation, the generated different material layers are stable, accuracy is high, the combined type dry method vertical coal separator can be made to be quite high, the occupied area is small compared with that of a horizontal separator, the coal separation amount is large, and the combined type dry method vertical coal separator is suitable for large-scale coal separation.
Description
Technical field
The invention belongs to dry coal preparation technical field, specifically relate to a kind of separator for vertical sorting coal.
Background technology
Current medium technique, common selection by winnowing and dry coal preparation equipment, generally use the horizontal separator of combined type dry method, its sorting of wind realization to raw coal mainly relying on the electromagnetic vibrator after being arranged on horizontal sorting bed and blast bottom sorting bed, successively discharge cleaned coal and spoil, but, its sorting raw coal amount is limited, and be applicable to small-scale, sorting amount is little, production efficiency is low, and sharpness of separation is not high.
Summary of the invention
The object of this invention is to provide a kind of vertical sorting bed (vertical coal picker), improve coal separation amount and coal separation precision.
For this reason, the vertical coal picker of combined type dry method provided by the invention, comprises tubular shell and the coaxial and cylindrical support be arranged in this tubular shell with this tubular shell;
The outer wall of this cylindrical support is from up to down provided with multilayer steps formula swivel chute, the outer face of this step swivel chute is fixed on the inwall of tubular shell;
The top seal of cylindrical support forms blind end, and the end face of this blind end is provided with electromagnetic vibrator;
The bottom of tubular shell offers the cleaned coal discharging opening just right with the bottom of the base frame stepwise swivel chute being placed in the bottom and spoil discharging opening.
The top of tubular shell is provided with the material diversion pipe of lower ending opening and the cavity between tubular shell and cylindrical support.
Advantage of the present invention is: by multi-stage stairs formula swivel chute, carry out multipass sort to raw coal, and the Different layer of the compost of generation is stablized, precision is high, and the vertical coal picker of this tubular can do very high, floor space horizontal separator of comparing is little, and coal separation amount is large, be applicable to extensive coal separation.

Fig. 1 is the structural representation of the vertical coal picker of combined type dry method.
Description of reference numerals: 1, tubular shell; 2, cylindrical support; 3, step swivel chute; 4, electromagnetic vibrator; 5, material diversion pipe; 6, base frame stepwise swivel chute; 7, cleaned coal discharging opening; 8, spoil discharging opening.
Detailed description of the invention
Little in order to overcome existing Duplex dry separator sorting amount, the defect low with precision can not be applied on a large scale, present embodiments provide the vertical coal picker of combined type dry method shown in a kind of Fig. 1, comprise tubular shell 1 and the coaxial and cylindrical support 2 be arranged in this tubular shell 1 with this tubular shell 1; The outer wall of this cylindrical support 2 is from up to down provided with multilayer steps formula swivel chute 3, the outer face of this step swivel chute 3 is fixed on the inwall of tubular shell 1; The top seal of cylindrical support 2 forms blind end, and the end face of this blind end is provided with electromagnetic vibrator 4; The bottom of tubular shell 1 offers the cleaned coal discharging opening 7 just right with the bottom of the base frame stepwise swivel chute 6 being placed in the bottom and spoil discharging opening 8.The top of tubular shell 1 is provided with the material diversion pipe 5 of lower ending opening and the cavity between tubular shell 1 and cylindrical support 2.
Sorting material i.e. broken rear raw coal to be selected enters top layer step swivel chute 3 through material diversion pipe 5, and rotate along every one deck step swivel chute around cylindrical support 2, in the process of rotating, often leave a step swivel chute, sorting material will be once unsettled, must by centrifugal force redistribution once, again because the frictional force between solid material is greater than rotary centrifugal force, cause sorting material can only distribute once when pan feeding, and just cannot redistribute again once the formation bed of material, like this, in the process that sorting material rotates along multilayer steps formula swivel chute, repeatedly sorting must be formed, cleaned coal and gangue sorting are carried out layer by layer, cleaned coal and spoil are repeatedly distributed, until discharge in the bottom of the bottom stage formula swivel chute of the bottom from cleaned coal discharging opening and spoil discharging opening.
As can be seen here, the vertical coal picker of combined type dry method that the present embodiment provides, by multi-stage stairs formula swivel chute, carry out multipass sort distribution to raw coal, the Different layer of the compost of generation is stablized, and precision is high, and the vertical coal picker of this tubular can do very high, floor space horizontal separator of comparing is little, and coal separation amount is large, is applicable to extensive coal separation.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
