That realizes that said method the present invention can provide multiple pattern falls the stream jigging machine, only combines two sections air impulsive motion coal separations to do further to launch explanation with jigging machine among the embodiment:
Embodiment 1; Among Fig. 1, a kind of two sections air impulsive motion coal separations are with falling the stream jigging machine, and it comprises control device, bellows, discharge device, body 1 and the choke apparatus 13 of existing jigging machine; The control device of wherein said existing jigging machine, bellows, discharge device are prior art, here no longer narration.Said existing jig body 1 comprises that shape, structure, material therefor, the effect of spoil section body 2 and middle coal section body 3 also are prior art, also no longer narration here.During being installed in, 13 of said choke apparatus in the coal section body 3, said choke apparatus 13 is not installed in the spoil section body 2.Said choke apparatus 13 is the cylinder of a uiform section; Its material can be steel or stainless steel, can also be other material or composite, and its cross sectional shape can be the wing or various streamlineds of plate shape; Other shape also; This cylinder solid also can be made hollowly, and the length of this cylinder equals said jig body inner width; Fixedly mount on the direction perpendicular to the flow direction of said choke apparatus 13 coal section bed 12 in said; Also can in guaranteeing use, the activity of up-down adjustment install, said choke apparatus 13 length directions in back are installed kept level, the said choke apparatus 13 in installation back is divided into former and later two parts to the top layer of coal section bed 12 in said.
During present embodiment work, be ready to jigging machine and each accessory system earlier, be in and treat duty, and complete bed, fills with water, start-up system, adjustment geomantic omen parameter; After getting into operate as normal, the raw coal from spoil section bed 11 inlets add at first begins conventional preliminary layering under the effect of fluctuating flow up and down in spoil section bed 11; In the assorting room, the heavy fine of part passes through for 4 times through spoil section sieve plate, and other material flows to 11 outlets of spoil section bed under the effect of horizontal current; After the raw coal of accomplishing preliminary layering reached 11 outlets of spoil section bed, the spoil product that is sub-elected was controlled down row through spoil discharge road 6 through discharge device as required, and and sieve product thoroughly and mix, from 8 discharges of spoil discharge gate.Cleaned coal that is sub-elected and middle product of coal be the therefrom inlet of coal section bed 12 entering then, enters into the material of coal section bed 12, at first the further sorting of routine in the forward part of falling stream district 15 that choke apparatus 13 forms; In the assorting room, the heavier fine of part passes through for 5 times through middle coal section sieve plate, and other material moves to choke apparatus 13 under the effect of horizontal current; After being reached choke apparatus 13 by sorting material, the bed under the choke apparatus 13 is unaffected, can directly pass through for 13 times from choke apparatus, enters in the back segment that falls stream district 15; Can not from choke apparatus pass through for 13 times by sorting material and superficial water, then pass through from choke apparatus 13 tops, get into and to fall stream district 15; In falling stream district 15, fall the stream negative pressure on the one hand, the bottom horizontal flow sheet current have produced local ravel area 14 at the rear portion of set choke apparatus 13 on the other hand; Entering fall stream district 15 by sorting material; Heavier fine gathers under the help of gravity and negative pressure in the ravel area 14 of falling in the stream district 15 relatively in falling the flow field of stream; Under the effect of fluctuating flow motion up and down; Gathered the relative heavier fine of ravel area 14, sent into the inner further sorting of bed through said ravel area 14; Through after falling stream district 15, also entered into operation in the back segment that falls stream district 15 by sorting material; Material in this section is further accomplished last routine by density stratification work in the fluctuating flow up and down; Accomplish material after the accurate layering arrive in after 12 outlets of coal section bed, the middle product of coal that is sub-elected through middle coal discharge road 7, is controlled down row through discharge device as required, and and sieve product thoroughly and mix therefrom coal discharge gate 9 discharges; Cleaned coal that is sub-elected and aquatic products are therefrom outlet cleaned coal discharge gate 10 discharges of coal section bed 12 then, accomplish whole assorting room.Thereby so continue to accomplish the sorting work of raw coal, realized that air impulsive motion falls the coal washing of stream jigging.
Based on same principle and method; The present invention also can be in the middle coal section bed 12 like the middle coal section body 3 among Fig. 1; On the flow direction of bed; Equidistance or not equidistance or according to certain rules two or more said choke apparatus 13 are set, form twice or multiple tracks and fall stream, accomplish twice or many sortings.A said back choke apparatus will be lower than previous, and the discrepancy in elevation between the adjacent two choke apparatus horizontal planes also can be controlled in 50mm to the some values between the 200mm, and increases the upper groove body of said jig body is corresponding.Can reach goal of the invention equally.
Based on same principle and method, the present invention also can be controlled at 50mm to the height of said choke apparatus 13 to the some optimum values between the 500mm in like Fig. 1.Can reach goal of the invention equally.
Based on same principle and method, the present invention also can be in like Fig. 1 be located at plane on the said choke apparatus 13 and be lower than the some optimum value of said jig body 200mm suitable for reading to 300mm.Can reach goal of the invention equally.
Based on same principle and method, the present invention also can be reduced to a spoiler to said choke apparatus 13 in like Fig. 1.Equally also can reach goal of the invention.
Based on same principle and method, the present invention also can be inserted into said bed to the bottom of said choke apparatus 13 in like Fig. 1 top is to the some optimum positions between the bottom.Can reach goal of the invention equally.
Based on same principle and method, the present invention also can use the 26S Proteasome Structure and Function like the said choke apparatus 13 of Fig. 1 on the single stage jigging machine, constitutes single hop and falls the stream jigging machine, can reach goal of the invention equally.
Based on same principle and method, the present invention also can realize as described in Figure 1 26S Proteasome Structure and Function, can reach goal of the invention equally on three sections or multistage jigging machine.
Based on same principle and method, the present invention also can reach goal of the invention with realizing on the jigging machine of other form or other purposes like the described 26S Proteasome Structure and Function of Fig. 1 equally.
In sum, a kind of falling of the present invention flowed the jigging method for separating and falls the stream jigging machine, in the jigging method for separating and equipment of routine; Increase and fall the stream motion, obtain effective sorting to the thin material of a part and the difficult sorting material that in the top layer, flow, can reach the raising sharpness of separation; Improve the effect of treating capacity; When particularly too much the or last ore deposit of sorting bed top occurs and is prone to harden at fine particle content, can improve the upper strata separating effect, and enlarge lower limit of separation.This method also lets the flowing water flow energy participate in sorting in industry first.
The invention discloses a kind of falling flows the jigging method for separating and falls the stream jigging machine; Though more than enumerated less embodiment; But for those of ordinary skill in the art; To some remodeling that the present invention did, improvement, replacement etc., perhaps above-mentioned embodiment is made any combination and variation, all drops within protection scope of the present invention.
