That realizes that said method the present invention can provide multiple pattern falls the stream jigging machine, only does further to launch explanation in conjunction with two sections air impulsive motion coal separations 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.Described 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 described choke apparatus in the coal section body 3, described choke apparatus 13 is not installed in the spoil section body 2.Described 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, its cross sectional shape can be the wing or various streamlineds of plate shape, other shape also, this cylinder solid, also can make hollow, the length of this cylinder equals described jig body inner width, fixedly mount on the direction perpendicular to the flow direction of described choke apparatus 13 coal section bed 12 in described, also can in guaranteeing use, the activity of up-down adjustment install, described choke apparatus 13 length directions in back are installed are kept level, the described choke apparatus 13 in back is installed the top layer of coal section bed 12 in described is divided into former and later two parts.
In present embodiment when work, be ready to jigging machine and each accessory system earlier, be in and treat duty, and complete bed, fill with water, start-up system, adjustment geomantic omen parameter; After entering operate as normal, from the raw coal that spoil section bed 11 inlets add, the at first conventional preliminary layering of beginning under the effect of fluctuating flow up and down in spoil section bed 11; In the assorting room, the heavy fine of part is saturating by spoil section sieve plate 4 times, and other material flows to 11 outlets of spoil section bed under the effect of horizontal current; After the raw coal of finishing preliminary layering reached 11 outlets of spoil section bed, the spoil product that is sub-elected was controlled down row by spoil discharge road 6 as required through discharge device, and mixed with saturating sieve product, discharged from spoil discharge gate 8.By the cleaned coal that sub-elected and middle product of coal then therefrom the inlet of coal section bed 12 enter, enter 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 is saturating by middle coal section sieve plate 5 times, 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, enter and fall stream district 15; In falling stream district 15, fall miscarriage on the one hand and give birth to negative pressure, 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; Enter 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 by described ravel area 14; By 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 finished last routine by density stratification work in the fluctuating flow up and down; Finish material after the accurate layering arrive in after 12 outlets of coal section bed, the middle product of coal that is sub-elected by middle coal discharge road 7, is controlled down row as required through discharge device, 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, finish whole assorting room.Thereby so continue to finish 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 as the middle coal section body 3 among Fig. 1, on the flow direction of bed, equidistantly or not equidistantly or according to certain rules two or more described choke apparatus 13 are set, form twice or multiple tracks and fall stream, finish twice or many sortings.A described 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 described jig body is corresponding.Can reach goal of the invention equally.
Based on same principle and method, the present invention also can be in as Fig. 1 as described in the height of choke apparatus 13 be controlled at 50mm to the some optimum values between the 500mm.Can reach goal of the invention equally.
Based on same principle and method, the present invention also can be in as Fig. 1 as described on the choke apparatus 13 plane be located at be lower than as described in jig body 200mm suitable for reading to some optimum values of 300mm.Can reach goal of the invention equally.
Based on same principle and method, the present invention also can be in as Fig. 1 as described in choke apparatus 13 be reduced to a spoiler.Equally also can reach goal of the invention.
Based on same principle and method, the present invention also can be in as Fig. 1 as described in the bottom of choke apparatus 13 can be inserted into as described in the top of bed 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 of choke apparatus 13 as described in Figure 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 realize 26S Proteasome Structure and Function as described in Figure 1, can reach goal of the invention equally on the jigging machine of other form or other purposes.
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, the thin material of a part and the difficult sorting material that flow in the top layer are obtained effective sorting, can reach the raising sharpness of separation, improve the effect for the treatment of capacity, when particularly too much the or last ore deposit of sorting bed top occurs and easily hardens at fine particle content, can improve the upper strata separating effect, and lower limit of separation is enlarged.This method also allows 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 done any combination and is changed, and all drops within protection scope of the present invention.
