Abstract
The invention provides an oil shale jigging method and jigging machine. Stepped multi-step air inlet is adopted in an air inlet period of a jigging cycle. One jigging cycle of the method consists of a stepped multi-step air inlet period, a one-step expansion period, a one-step exhausting period and a one-step rest period, wherein stepped multi-step air inlet consists of a N-times air inlet period and a N-1-times expansion period. By adopting the oil shale jigging method and jigging machine to carry out jigging washing dressing on oil shale ores, a better layering effect can be realized by a jigger-bed layer, dressing precision which is unattainable in the prior art is obtained, the oil content of concentrates is further increased, the grade of tailings is effectively reduced, and treatment capability can be improved. The oil shale jigging method belongs to one novel oil shale jigging method. The technology also can be applied to the dressing of other high-specific-gravity ores and the dressing of other heavy ores with small dressing density differences.

Specific embodiment
Embodiment 1：Below in conjunction with accompanying drawing, jumped with conventional single-stage compound air chamber air impulsive motion
Eliminate as a example by machine, one embodiment of the present of invention is further described：
As shown in figure 1, a kind of oil shale jigging method of the invention, its jigging cycle is by ladder
Formula multistep charging period 1, a step phase of expansion 2, a step exhaust cycle 3, step stand-down 4 etc. four
Divide and constitute.Wherein：The staged multistep charging period 1 includes staged first step air inlet rank again
Section 5, staged first step expansion stage 6, staged second step charging stage 7, staged the
Two step expansion stages 8, the step charging stage 9 of staged the 3rd.
In work, in conventional single-stage compound air chamber air pulsating jig, jigging cycle elder generation
Start to perform staged multistep charging period 1, state is that air bleeding valve is whole closes, during only control
The on off state and time length of intake valve processed, process is：Intake valve is first turned on, on demand
The control opening time, the staged first step charging stage 5 is completed, bed material exists during being somebody's turn to do
Under the promotion of air inlet, accelerate upwards；To after the motion state of setting, intake valve is closed,
The shut-in time is controlled on demand, completes the staged first step expansion stage 6, bed during being somebody's turn to do
Material continues up retarded motion in the presence of inertia；To after the motion state of setting, then
Intake valve is opened, the opening time is controlled on demand, complete the staged second step charging stage 7,
Bed material continues up accelerated motion under the promotion again of air inlet during this；To setting
Motion state after, turn off intake valve, control the shut-in time on demand, complete staged the
Two step expansion stages 8, bed material continues up deceleration in the presence of inertia during being somebody's turn to do
Motion；To after the motion state of setting；Intake valve is opened again, and the opening time is controlled on demand,
Complete the step charging stage 9 of staged the 3rd, should during bed material under the promotion of air inlet,
Accelerate again up；After reaching the state of needs, finally close intake valve and complete air inlet work
Make.Jigging cycle starts to perform a step phase of expansion 2, shape after completing staged multistep charging period 1
State is intake valve, air bleeding valve is whole closes, during only control the shut-in time length of two valves,
In the presence of inertia, a step completes upward retarded motion to the stage bed material.Reach rule
After fixed state, jigging cycle starts to perform a step exhaust cycle 3, and state is that intake valve is whole closes
Close, during only control the opening time length of air bleeding valve, should during bed material downward
In the presence of current, a step completes to move downward.Air bleeding valve is closed after reaching predetermined state, it is complete
Into a step exhaust cycle 3.Last jigging cycle performs a step stand-down 4, and state is intake valve, row
Air valve is whole to close, during only control the shut-in time length of two valves, bed thing in the stage
Under the collective effect of inertia and sieve plate, a step completes motion of stopping to material.
