Step swivel chute comprises the downward chute groove face of rotation and is connected and rotates the substrate to downward-extension with cylinder pillar is vertical, and chute groove face is fixed on the end face of substrate;
Angle between the cross section of the chute groove face of every layer of step swivel chute and corresponding substrate successively reduces from top to bottom.
The top of tubular shell is provided with the material diversion pipe of the cavity of lower ending opening between tubular shell and cylinder pillar.
Angle value between cross section and the horizontal plane of chute groove face is large or equal 10 ° and little or equal 50 °.
Step swivel chute is four layers, and angle from top to bottom, between cross section and the horizontal plane of the chute groove face of each layer of step swivel chute is 30 °, 20 °, 10 ° and 5 ° of decline trend settings successively.
Step swivel chute is four layers, and the angle of inclination of the step swivel chute of upper three layers is all set to downward-sloping 45 °, and the bottom is set to downward-sloping 35 °.
The utility model has the advantages that: by multi-stage stairs formula swivel chute, raw coal is carried out to multipass sort, the Different layer of the compost producing is stable, precision is high, and it is very high that the vertical coal picker of this tubular can do, the floor space horizontal separator of comparing is little, and coal separation amount is large, be applicable to extensive coal separation, sharpness of separation is high.

Detailed description of the invention
Little in order to overcome existing Duplex dry separator sorting amount, can not apply on a large scale the defect low with precision, the present embodiment provides the combined type dry method shown in a kind of Fig. 1 vertical coal picker, comprises tubular shell 1 and coaxial and be arranged on the cylinder pillar 2 in this tubular shell 1 with this tubular shell 1; On the outer wall of this cylinder pillar 2, be 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 cylinder pillar 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 cleaned coal discharging opening 7 and the spoil discharging opening 8 just right with the bottom of base frame stepwise swivel chute 6 that is placed in the bottom.The top of tubular shell 1 is provided with the material diversion pipe 5 of the cavity of lower ending opening between tubular shell 1 and cylinder pillar 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 around cylinder pillar 2 along every one deck step swivel chute, in the process of rotating, often leave step swivel chute one time, sorting material will be once unsettled, redistributed once by centrifugal force, again because the frictional force between solid material is greater than rotary centrifugal force, cause sorting material in the time of pan feeding, to distribute once, once and the formation bed of material just cannot redistribute again, like this, in the process that sorting material rotates along multilayer steps formula swivel chute, must form repeatedly sorting, cleaned coal and gangue sorting are carried out layer by layer, cleaned coal and spoil are repeatedly distributed, until discharge from cleaned coal discharging opening and spoil discharging opening in the bottom of the bottom stage formula swivel chute of the bottom.
Step swivel chute 3 comprises the downward chute groove face 9 of rotation and is connected and rotates the substrate 10 to downward-extension with cylinder pillar 2 is vertical, and chute groove face 9 is fixed on the end face of substrate 10; Angle between the cross section of the chute groove face 9 of every layer of step swivel chute 3 and corresponding substrate 10 successively reduces from top to bottom.
Suggestion from top to bottom, angle value between every layer of chute groove face 9 and horizontal plane is between 50 ° to 10 °, as shown in Figure 2, from top to bottom, angle between chute groove face 9 and the horizontal plane of each layer of step swivel chute 3 is 30 °, 20 °, 10 ° and 5 ° of decline trend settings successively, so form step sorting, contribute to layering and point band of material sorting, upper urgency (concentration criterion is more violent), lower slow, can guarantee that the precision of material sorting can guarantee again the discharge of the material after sorting, realize well point band.
Angle of inclination that can certainly upper three layers is set to downward-sloping 45 °, and the bottom is set to 35 °, and it is 45 ° that the angle under being tilted to of substrate 10 is set to three layers equally, and the bottom is 35 °.These technology essential factors require to carry out flexible design and making according to concrete site operation, needn't stick to the parameter designing that the present embodiment provides.
The effect of step swivel chute 3 makes sorting material every through a step, and the unsettled centrifugal force that is just subject to of the bed of material redistributes once.Once forming the bed of material just cannot redistribute again.The innovative design of step swivel chute 14, has simulated the repeatedly situation of pan feeding, has realized repeatedly distributing again of light-heavy material, has reached the object of weight solid material sorting.
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, raw coal is carried out to multipass sort distribution, the Different layer of the compost of generation is stable, precision is high, and it is very high that the vertical coal picker of this tubular can do, the floor space horizontal separator of comparing is little, and coal separation amount is large, be applicable to extensive coal separation, and sharpness of separation is high.
More than exemplifying is only to illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, within the every and same or analogous design of the utility model all belongs to protection domain of the present utility model.
