Abstract
The utility model discloses a discharging device for a jigger, particularly a large material discharging device for the jigger. The utility model comprises a buoy, a discharging passage, a discharge opening, an overflow dam and a control mechanism. The discharge opening is provided with a shutter. A part of a jigging chamber of the utility model extends into the discharging channel. A bridge type wind channel which is communicated with the discharging channel is arranged above the discharging channel, and an exhaust valve is arranged on the bridge type wind channel. The rise and fall of the shutter and the opening degree of the exhaust valve are controlled by the control mechanism. Automatic control for discharging speeds can be realized through controlling the rise and fall of the shutter and the opening degree of the exhaust valve. The utility model has the advantages of simple and reasonable structure, reliable work and high automation.
Description
The utility model relates to a kind of discharge device of jigging machine, particularly a kind of jigging machine bulk materials tapping equipment.
The quality of discharge device is to influence one of the production capacity of jigging machine and crux equipment of separating effect, after material has divided level by proportion, having only accurately, in time and continuously, discharge could guarantee the stable of bed, the product quality that obtains just can be high, present pan feeding for the 250-13mm grade, still be extensive use of refuse rotor and carry out discharge, but it obviously exists deficiency, the material and the phenomenon that is stuck often appear leaking, discharge device can not normally be worked continuously, promptly influence coal separation efficient, also influenced product quality.
The purpose of this utility model is exactly that a kind of simple and practical, reliable operation, jigging machine bulk materials tapping equipment that automaticity is high will be provided.
The utility model adopts technical scheme as described below for achieving the above object: jigging machine bulk materials tapping equipment comprises buoy, discharge road, discharge gate, downflow weir and controlling organization, there is flashboard at the discharge gate place, flashboard is controlled its lifting by the flashboard hoisting mechanism in the controlling organization, also has the buoy sniffer in the controlling organization.The part of jigging machine jigging chamber is stretched in the discharge road, and the bridge type air passage that is communicated with is arranged with it at top, discharge road, is equipped with air bleeding valve on the bridge type air passage, and stretching on the sidewall of the jigging chamber in the discharge road has the bank plate that exceeds sieve plate.
The flashboard hoisting mechanism drives the flashboard lifting by the DKJ YE by one group of rocker-arm link, the opening degree of air bleeding valve is also controlled by the DKJ YE, the actuating signal of DKJ YE comes from the buoy sniffer, realizes automatic control to discharge velocity by the opening degree of control lifting of flashboard and air bleeding valve.
Adopt the jigging machine bulk materials tapping equipment of this structure simple and reasonable, reliable operation, automation wheel degree height, under certain condition can the autobalance withdrawal rate, and the discharge device phenomenon that is stuck can not appear.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a left view of the present utility model.
Fig. 3 is a fundamental diagram of the present utility model.
With reference to Fig. 1, Fig. 2.Jigging machine bulk materials tapping equipment comprises buoy (12), discharge road (5), discharge gate (14), downflow weir (4), controlling organization (11), discharge gate (14) has been located flashboard (9), flashboard (9) upper articulation has shadoof (10), flashboard hoisting mechanism and buoy sniffer are arranged in the controlling organization (11), the flashboard hoisting mechanism is made up of DKJ YE and one group of rocker-arm link, the flashboard hoisting mechanism drives the lifting of flashboard (9) by shadoof (10), and the information of the heavy material thickness that the buoy sniffer will be elicited by buoy (12) receives, handle, pass to the DKJ YE after the amplification.
The part of jigging machine jigging chamber (6) is stretched in discharge road (5), the bridge type air passage that is communicated with is with it arranged at top, discharge road (5), bridge type air passage is made up of crosswind road (3), (3 ') and beam wind road (2), be equipped with air bleeding valve (1) on beam wind road (2), the opening degree of air bleeding valve is controlled by the DKJ YE in the controlling organization.
Stretch on the sidewall of the jigging chamber in discharge road (5) the bank plate (13) that exceeds sieve plate is arranged.
With reference to Fig. 3.During work, survey the thickness of the weight bed of material by buoy, the lifting of this signal controlling flashboard (9) of controlling organization root a tree name, thereby the aperture of control discharge gate (14), under the normal condition, the height of discharge opening is positioned at following weight bed of material place, separating density layer of living in position, and downflow weir is on separating density layer position, form downflow weir control thickness of bed layer, discharge gate aperture control discharge thickness, and separating density layer between, create conditions for more accurately carrying out the product separation by separating density, bank plate (13) but the grade of height root a tree name sorting material change, its effect is to allow a part of heavy material temporarily accumulate, so that control.
During work, event exhaust valve (1) is closed, pressure in discharge road and the bridge type air passage can constantly increase, during last balance, the part sieve plate (7) that sieve plate (8) is stretched in discharge road (5) is gone up with regard to the pulse free current, heavy material is not arranged, when air bleeding valve is opened, the discharge road leads to the atmosphere release, it is big that the fluctuating flow amplitude that sieve plate (7) is located becomes, the heavy material mass rate of emission is accelerated, the amplitude of the fluctuating flow that the opening degree of air bleeding valve and sieve plate (7) are located is approximated to linear relationship, and the DKJ YE is controlled the aperture of the opening degree and the discharge gate of air bleeding valve simultaneously, reaches the purpose of automatic control discharge velocity with this.
This discharge device under certain condition can the autobalance withdrawal rate.When weight bed of material thickening, fluctuating flow increases at the resistance in A district, backwater presses liter, when if the height of the open degree of the Lift of discharge gate, air bleeding valve and bank plate is all constant, the varied in thickness of B district bed is little, and bed resistance changes also little, so the moving enhancing of the fluctuating flow wink in B district, the mass rate of emission of heavy product increases, till recovering original heavy material layer thickness and original backwater pressure.In actual the use, when jigging machine stopped expecting midway, though discharge device is unjustified, withdrawal rate can reduce even stop automatically.
