Detailed description of the invention
Existingly overcome that the efficiency that existing dry separation and horizontal sorting exist is low, small scale, ratio defective product are low, production cost is high and the problem of the wasting of resources to overcome, present embodiments provide the vertical separator of multistage combined 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 main electromagnetic vibrator 4, in order to produce vibrations, improve solid material flowing property, the layering of strengthening material weight, be beneficial to the sorting material (raw coal to be selected) entered and shake layering, and in order to make sorting material separating effect more obviously and evenly, the present embodiment is circumferentially evenly provided with the secondary electromagnetic vibrator 10 shown in multiple Fig. 2 on the outer wall of tubular shell 1, corresponding to the middle position up and down of adjacent step swivel chute 3.
As seen from Figure 1, the cleaned coal chute 7 just right with the bottom of the base frame stepwise swivel chute 6 being placed in the bottom and slate chute 8 is offered in the bottom of tubular shell 1, and between cleaned coal chute 7 and slate chute 8, be provided with the plate 9 separating heavy particle and light grains, this plate 9 can along the face, outer side shield place of cleaned coal chute 7 obliquely or downwards, sliding near or sliding far away to tubular shell 1 inwall, to change the size of the aperture of slate chute 8 entrance, and then the adjustment realized spoil load, thus the control realized the combustion heat value of product, it is made to meet the real requirement of different occasion, farthest utilize spoil, and avoid production and the waste of a large amount of spoils, thus improve the effective and reasonable utilization of ratio defective product and resource, reduce production cost.
Wherein, the effect of the step swivel chute 3 of rotary setting makes sorting material often through a step, and the bed of material is unsettled just by centrifugal force redistribution once.Just cannot redistribute again once the formation bed of material.The innovative design of step swivel chute 3, simulates repeatedly the situation of pan feeding, achieves repeatedly distributing again of light-heavy material, reaches the object of weight solid material sorting.
As seen from Figure 1, this step swivel chute 3 comprises the downward chute groove face 11 of rotation and is connected with cylindrical support 2 is vertical and rotates the substrate 12 to downward-extension, and chute groove face 11 is fixed on the end face of substrate 12; Angle between the cross section of the chute groove face 11 of every layer of step swivel chute 3 and corresponding substrate 12 successively reduces from top to bottom; Suggestion from top to bottom, angle value between every layer of chute groove face 11 and horizontal plane is between 50 ° to 10 °, as shown in Figure 3, from top to bottom, angle between the chute groove face of each layer step swivel chute 14 and horizontal plane is arranged in 30 °, 20 °, 10 ° and 5 ° of decline trends successively, so forming station stepwise 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.
The angle of inclination of upper three layers can certainly be set to downward-sloping 45 °, the bottom is set to 35 °, and it is 45 ° that the angle under being tilted to of substrate 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, need not stick to the parameter designing that the present embodiment provides, be beneficial to solid particle flow and sorting in principle.
As shown in Figure 4, cylindrical support 2 offers the air intake passage coaxial with it, air intake interface 13 is offered bottom this air intake passage and cylindrical support 2, cylindrical support 2 between the chute groove face 11 of each layer step swivel chute 3 more than the bottom and corresponding substrate 12 is provided with discharge pipe 14, it extends to tubular shell 1 from cylindrical support 2, and this discharge pipe 14 is provided with multiple exhaust vent of being axially evenly arranged along discharge pipe 14 or wind groove 15, and this exhaust vent or wind groove 15 are arranged outward towards the cross section of chute groove face 11, with to the sorting material after unsettled to up-draught, the suspending power of simulation fluid, to increase material air gap, improve material fluidity, improve material eduction and eliminate local stoppages.Be illustrated in figure 5 the schematic diagram setting out airduct 14 between continuous three layers of step swivel chute 3.
Rotating guide 16(inwall corresponding to the tubular shell 1 at the outer rim place of every layer of step swivel chute 3 is inwardly provided with, extended obliquely also can be referred to as cross section rotary steering plate), this rotating guide 16 is fixedly connected with tubular shell 1 by arcwall face, as shown in Figure 3, bottom rotating guide 16, outer end is connected with tubular shell 1 inside, simultaneously its lateral surface is fixedly connected with by the inwall of connecting plate 20 with tubular shell 1, and the length in rotating guide 16 arcuately direction equals the length of step swivel chute 3.
Due to the effect at centrifugal force and chute groove face 11 oblique angle, sorting material tendency is moved along sorting bed (namely along the outside of the chute groove face 11 of every layer of step swivel chute 3) outer flow measurement, due to the stop of tubular shell 1 and chute groove face 11, the centrifugal force that the sorting material flowing to outside is subject to produces component upwards, again due to the stop of rotating guide 16, produce again component to the inside, the compound action of two component, the sorting material flowing to outside is made to form inside the making a concerted effort of the cross section along sorting bed shown in rotation arrows in shown in Fig. 1 (instruction material cross section spin direction), then make under gravity this part sorting material formed final from lower end, outside upwards, inside rotary motion track, thus, the weight of sorting material is distributed in motion process ceaselessly change, thus substantially increase the separating effect of light-heavy material, improve sharpness of separation.
As shown in Figure 6, the outer wall of tubular shell 1 is upper and lower is respectively provided with four installation hooks be circumferentially evenly arranged, by wirerope, hook hanging at the seamless steel pipe that can be adopted 50mm by 4 steel column 17() on the rectangular frame of Combination Welding, this rectangular frame is provided with a spring base platform 18(corresponding to each hook place can adopt 6mm double-layer plate to make), rectangular frame is connected with hook by this spring base platform 18, thus tubular shell 1 is hung, and then realize hanging the vertical separator 3 of whole combined type dry method.Further, tubular shell 1 top is provided with the sorting material feed hopper that dust cover that soft filtering makes and lower end penetrate blanking in this dust cover, realizes passive filter dirt, has good environmental-protection function.
In sum, be not difficult to find out, the vertical separator of combined type that each embodiment provides above has the multilayer chute of tubular shell and Qi Nei, multilayer sorting can be realized in limited space, not only can improve the sorting amount of sorting material, and by multiple electromagnetic vibrators that repeatedly sorting and main electromagnetic vibrator and layering are evenly arranged, ensure that the lifting of sharpness of separation, and the discharge rate of spoil is regulated by plate, to produce the product of satisfied different occasion demand, farthest take full advantage of spoil, instead of worked as garbage disposal as traditional way and fall, not only rationally make use of resource fully, and reduce production cost.Meanwhile, its dust be discharged in air is all through process, meets environmental requirement.
