Description
Technical field
The present invention relates to a kind of dehydration and vibration sieve, particularly relate to a kind of dehydration and vibration sieve that can prevent from running material, for ore dressing, tailing dry row, the solid-liquid separation of aqueous mixture.
Technical background
When dehydration and vibration sieve normally works, mixed material enters from storage end, after vibration dehydration, siccative falls, after the compass screen surface port of export is discharged, gather materials belt or material-collecting funnel, containing more fine grain mixture (ore pulp) then through compass screen surface, it is pooled to siftage discharge gate after dropping to sieve the end discharge, is sent to next processing links.When dewatering screen inlet flow rate becomes big or feed thickness changes greatly, it may appear that ore pulp is directly fallen the belt that gathers materials or the situation of material-collecting funnel from compass screen surface outlet, this state once occurs, may cause the paralysis of whole processing system.
Summary of the invention
It is an object of the invention to provide a kind of dehydration and vibration sieve that can prevent from running material, this dehydration and vibration sieve solves when inlet flow rate becomes big or feed thickness changes greatly, on compass screen surface, the mixture (such as ore pulp) of excess can directly fall the belt that gathers materials from the compass screen surface port of export or the problem of material-collecting funnel, it is to avoid race material accident generation.
Technical solution:
The present invention includes: sieve nest, and described sieve nest includes: bottom screening plate, screen cloth, side plate, siftage go out funnel.When sieve nest is horizontally mounted, bottom screening plate and the most inclined layout of screen cloth, the sieve plate at its discharge end, higher than the sieve plate of feeding end, is being provided with baffle plate on the side plate of feeding end, and baffle plate is provided with overfall, and the height and position of overfall is less than the height of discharge end.
Further: sieve plate is divided into former and later two separate planes with siftage discharging hopper centre line for boundary；When sieve nest is horizontally mounted, two the most inclined layouts of separate planes before and after described piece of sieve plate, least significant end intersects directly over discharge bucket, forms fold-line-shaped screen cloth face low between a two ends senior middle school；It is bottom screening plate parallel with it below described screen cloth, is provided with therebetween siftage flow clearance.
Further: sieve nest is supported on sieve nest bearing by supporting spring, and siftage to go out funnel corresponding with the aggregate bin on bearing.
Advantages of the present invention:
Described dehydration and vibration is being provided with the baffle plate of carry potential overflow mouth on the side plate of feeding end, and the height and position of overfall is less than the height of discharge end.When dewatering screen inlet flow rate becomes big or feed thickness changes greatly, unnecessary material will discharge setting position from overfall, successfully solve feeding coal big time from discharge end compass screen surface, run the problem of material, reliable operation.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Embodiment 1
The present invention includes sieve nest bearing 1 and the aggregate bin 2 being fixed to the upper, supports spring 3, also include sieve nest 7, vibrator 6, sieve plate 5, siftage discharging leak 4, bottom screening plate and side plate, described sieve nest 7 uses by the bathtub construction of Plate Welding, it is being provided with baffle plate on the side plate of feeding end, baffle plate is provided with overfall B, the height and position of the overfall B height less than discharge end A, but higher than the sieve plate height above the mouth 4 that gathers materials, as shown in Figure 1.
Described sieve plate 5 goes out funnel 4 centrage with siftage and is divided into former and later two separate planes for boundary；When sieve nest 7 is horizontally mounted, two the most inclined layouts of separate planes before and after described piece of sieve plate, least significant end intersects directly over discharging opening 4, forms fold-line-shaped screen cloth face low between a two ends senior middle school；It is bottom screening plate parallel with it below described screen cloth, is provided with therebetween siftage flow clearance.
Siftage discharge outlet is provided with on material-collecting funnel 4, and is fixed on sieve nest 7.
1) when using, described sieve nest bearing 1 horizontal positioned.
2) sieve nest 7 supports spring 3 by 4 (group) and is supported on sieve nest bearing 1, and siftage to go out funnel 4 corresponding with the aggregate bin 2 of 1 on bearing.
3) described vibrating-dewatering screen uses double oscillating electromotor self-synchronization exciting device 6, and the force action line of exciting force is by sieve nest barycenter, and before and after guarantee, spring is zero to the resultant moment of sieve nest barycenter.Sieve nest now can be made to produce straight-line oscillation in s direction.
4) being provided with horizontal overfall B at feeding end near side plate appropriate position, the left side, the height and position of B is less than the height of discharging port A, but is higher than the most significant end position of pan feeding side screen cloth, as shown in Figure 1.
5) mixed material is directly entered dewatering screen from storage end (left end of Fig. 1) top.
Work process
During the work of described vibrating-dewatering screen, whole sieve nest 7 makees reciprocating linear vibration in s direction.After mixed material enters dewatering screen above storage end, large granular materials moves along sieve plate 5 upper surface to discharge end A direction, until discharging from discharge end.Meanwhile, small particles material and water thoroughly sieve the gap between tailing edge screen cloth and bottom screening plate and flow to out funnel 4, naturally drop in the aggregate bin 2 being fixed on bearing 1.
When described dewatering screen inlet flow rate becomes big or feed thickness changes greatly, the mixed material having more runs past overfall B and is directly discharged into aggregate bin 2 below by going out funnel 4 from screen cloth.Owing to the position than discharge end B, the position of overfall is lower, therefore the mixed material having more will not be discharged from dewatering screen discharge end.So, it is to avoid run the generation of material accident.Actually used showing, this structure is highly effective to preventing from running material.
Embodiment 2
As it is shown in figure 1, directly remove when gap flow export that funnel 4, small particles material and water sieve between tailing edge screen cloth and bottom screening plate thoroughly on the basis of embodiment 1, directly drop to the aggregate bin 2 being fixed on bearing 1, the most more save material.
