Vibrator makees synchronous backward operating, and component superposition of the centrifugal force caused by two groups of eccentric mass along direction of vibration, reversely centrifugation is supported
Disappear, so as to form the single excited vibration along direction of vibration, sieve nest is produced linear reciprocating motion；
(2) compass screen surface is made up of some screen stencil sheets, and screen stencil sheet can carry out different combinations according to the fineness of material, fully
Ensure the effect of dehydration, while dismount, be easy to maintenance, be easy to process, low manufacture cost；
(3) all screen stencil sheets of side close to side plate are pushed down by pressing plate, and pressing plate is by tapered wedges along material movement side
To compression, compaction degree is set to become better and better in process of production, pressing plate plays a part of compressing screen stencil sheet, also prevents side plate simultaneously
The effect of abrasion.
Further, discharge device is provided with the discharge outlet of the sieve plate, the discharge device includes Height Adjustable
Marker board, the marker board is connected with the side plate bolt by being arranged on the installing plate of its lower end, set on the installing plate
Have the open slotted hole passed through for bolt, by adjustment bolt open slotted hole locked position, to adjust the height of marker board.
It is using the above-mentioned further beneficial effect of technical scheme：The height adjustable of marker board, it is different according to material properties,
The residence time of material bed thickness and material on dewatering screen is adjusted, and then obtains optimal dehydrating effect and yield.
Further, the upper plane of the marker board is higher by the upper plane 5mm of sieve plate.
When adjustment is higher than sieve plate 5mm upwardly above by marker board, the discharge thickness of marker board can increase by 20~
35mm thickness, while the moisture content about 1~2% of substrate material can drop.
Further, the compass screen surface of the sieve plate uses polyurethane material.
It is using the above-mentioned further beneficial effect of technical scheme：Compass screen surface uses polyurethane material, and broken-up laying is in bottom
On discharge beam, dismounting is very convenient；Compared with the metallic screen web plate of routine, service life length, anti-wear performance is generally rigid material
More than 5 times of matter, and it is not easy loose, blocking.
Further, the inclination angle of the sieve plate and horizontal plane is -8 °.
It is using the above-mentioned further beneficial effect of technical scheme：High-frequency dewatering screen compass screen surface forms -8 ° of inclination angles with horizontal plane,
Reach for ore deposit concentration and fed for the material of ore deposit amount by bottom, from high-end discharge, increase residence time of the material on compass screen surface,
Greatly reduce the moisture content of material.
Further, connected between the side plate and crossbeam and motor mount with bolt or ring-grooved rivet.
It is using the above-mentioned further beneficial effect of technical scheme：Bolt or ring between side plate and crossbeam and motor mount
Groove rivet interlacement, it is firm in structure reliable.
