Description
Technical field
A kind of screening plant of the utility model coal mining processing technique field, and in particular to coarse-fine coal sieve bend impact
Device.
Background technology
In coarse-fine coal recovery system, sieve bend is fine cleaned coal predewatering device, and slurry passes through feed box with certain speed
Compass screen surface is fed from above along tangential direction, due to the effect of centrifugal force, slurry is close to compass screen surface movement.When slurry is by a grating
During staying to another grating, the arris of every grating all produces dissection to slurry.Cut slurry is centrifuging
Under the action of power, discharged through screen slot, become screenings；Cut slurry, which does not cross grating, becomes oversize.In the prior art
The defects of sieve bend, is：Sieve bend compass screen surface alters material seriously, influences the dehydrating effect of coarse-fine coal centrifuge, causes coarse-fine moisture content of coal
It is higher, seriously affect product quality.
The reason for causing sieve bend to alter material be：
1. the feed thickness shadow noon of sieve bend
There is very big influence in the feed thickness of sieve bend, feed thickness is too low to cause arc to the using effect of sieve bend
Sieve alters material seriously, influences desliming dehydrating effect, and when feed thickness is excessive, thin mud content increases in pan feeding, easily causes sieve pore blockade,
Influence desliming dehydrating effect.
2. the material size of sieve bend influences
The desliming dehydrating effect that the material size of sieve bend forms to sieve bend has a great influence, when in pan feeding close to sieve aperture ruler
When very little granule content is larger, the blocking of sieve aperture is easily caused, the desliming dehydrating effect of sieve bend certainly will be seriously affected.
3. the pan feeding initial velocity of sieve bend influences
Sieve bend pan feeding feeds sieve bend with the tangential direction that certain initial velocity arcuately sieves, and can be made when excessive velocities
Material is altered into compass screen surface, it has been observed that the pan feeding speed of sieve bend.
Pounder is added on the basis of original Vibration sieve arc reversal, according to the timing of the using effect of sieve bend to arc
Sieve compass screen surface is impacted, the particulate for blocking screen slot of shaking, and increases the permeable effect of compass screen surface.
Material phenomenon is altered for avoid sieve bend, mainly sieve bend is impacted using pounder in the prior art, at present
The supporting pounder of sieve bend mainly has machine driving and gas to be driven two kinds of forms, and mechanical pounder is as shown in Figure 1, this kind
Pounder uses center impact method, has following deficiency：1. impact position is in the middle part of sieve bend, and actual solid accumulation and stifled
Position is filled in arc lower part of screen, and it is poor that impact position impacts effect after deviateing.2. machine driving pounder is complicated, spring is easily broken
Split, and noise is big, cost is high, and maintenance is difficult.Using nearly 2 years, failure was more, have impact on continuous production, adds life
Produce cost.
