Abstract
The invention discloses a device for preventing thickener scum blockage. The whole device for preventing scum blockage is installed on a rabble arm through a single-lug support column and a double-lug support column, can rotate along with the rabble arm to skim and recover the scum, and does not need additional power. The combination mode of various units in the device can effectively skim and collect the scum, can perform the function of removing a certain moisture in the scum, and can recover and treat the scum, thereby avoiding influencing the subsequent production operation. The designed automatic creepage stirring wheel can automatically swing under the action of the scum and perform a stirring function on the scum, thereby preventing the excessive scum from blocking the scum recovery pipeline. The scum recovery pipeline has a wider top and a narrower bottom. The device can shorten the concentration settling time, prevents the scum blockage phenomenon, prolong the normal working period of the thickener and prolong the service life of the machine.
Description
Technical field
The present invention relates to a kind of concentrator offscum retracting device, especially one kind prevent concentrator offscum blocking device.
Background technology
Concentrator is widely used in ore dressing plant, and being mainly used in leachate concentration and wastewater treatment etc. needs the work of solid-liquid separation
Skill, by means of the effect being installed on the harrow frame of microrunning in concentrator, enters into concentrator by center column, perpendicular by charging
The deflector of the cylinder port of export, guides surrounding ore pulp into from charging column, so that ore pulp is spread to surrounding, enters preformed heavy mud
Layer, with material with forming mud layer together with the flocculant come in, and is deposited to the bottom of concentrator, and penetration by liquid sinks on mud layer
Rise, heavy mud layer has played filtration, so that particulate cannot be increased；Ore pulp produces motion in heavy mud layer, so that granule is connect with flocculant
Touch, continue to produce flocculation；Ore pulp containing solid weight is concentrated by the underflow ore deposit for thickening based on gravitational settling effect by gravitational settling
Slurry, makes the underflow ore pulp of thickening be drawn off by the underflow opening of dense motor spindle, the most of clear water separated in ore pulp is from dense
Machine downflow weir overflows naturally
In actual production process, due to the effect of ore pulp Chinese medicine, dense pool surface forms thicker slurry floating foam layer, and winter floats
Foam layer thickness does not occupy substantial amounts of settling section in concentrator, causes ore pulp up to 300mm, the thicker offscum layer in close machine surface
Run off, extend the settling ore pulp time；And because offscum layer is blocked up, promote liquid level in thickening pond to rise, ore pulp easily invades
The positions such as dense machine bearing, cause parts damages to aggravate, and impact concentrator normally runs, and causes huge economic loss.At present,
Some ore dressing plants process the formula mainly spray that there is offscum in small-sized concentrator and add defoamer, but two kinds of elimination offscums
Mode effect is all undesirable；Fountain eliminates offscum to be needed to use substantial amounts of water, and reduces concentrated effect, the use meeting of defoamer
Cause the inefficacy of foaming agent in subsequent production operation；Especially large-scale concentrator treating capacity is greatly it is more difficult to eliminate offscum in time.
Content of the invention
The purpose of the present invention is for defect present in prior art in concentrator offscum retracting device work process, and
There is provided one kind to prevent concentrator offscum blocking device, the offscum on concentrator surface can be removed, shorten the concentration and settlement time, extend
The concentrator normal work cycle.
The technical scheme is that one kind prevents concentrator offscum blocking device, propped up by monaural support column and ears
Dagger is installed in rake arms, including monaural support column, ears support column, offscum skim collection plate, connecting rod, fixed go water baffle plate,
Fixed water baffle plate strap, radial type is gone to go water baffle plate, radial type to remove water baffle plate strap, rotating shaft, stirring wheel, wheel
Axle, offscum recovery channel are it is characterised in that the upper end of described monaural support column and ears support column is connected with described connecting rod respectively
Connect, described offscum skims the side that collection plate is installed on described monaural support column and ears support column, described fixed go water baffle plate to lead to
Cross described fixed go water baffle plate strap and described offscum to skim collection plate to be connected, the side of described connecting rod is provided with described turn
Axle, articulated go water baffle plate to go water baffle plate strap hinged with described rotating shaft by articulated, described wheel shaft and
Described stirring wheel is fixed in described rotating shaft, and described offscum recovery channel is buckled in articulated going on water baffle plate.
Further, described offscum skims the side inward slant of collection plate.
Further, described offscum skim collection plate, fixed remove water baffle plate and radial type go water baffle plate enclose be connected into one straight
Angular zone, described fixed go water baffle plate with articulated go water baffle plate overlap.
Further, described rotating shaft, wheel shaft and stirring wheel can be wriggled with synchronous rotary, and can only be in ± 45 degree of scopes
Interior rotation, described wheel shaft goes water baffle plate setting angle to be 60 degree with articulated.
Further, described offscum recovery channel is type wide at the top and narrow at the bottom, and described wheel shaft and stirring wheel are located at described offscum
In recovery channel, described offscum recovery channel opening just removes water baffle plate to articulated, and exceeds described rotating shaft.
Further, articulated go between water baffle plate and described connecting rod, to leave offscum overflow gap.
Further, described rotating shaft two ends are respectively arranged with sealing device and containment vessel.
The invention has the beneficial effects as follows: whole offscum retracting device is installed on rake by monaural support column and ears support column
On arm, slash collection can be rotated together with rake arms and reclaim offscum, and not need extra power；Each plate in this device
Compound mode can effectively skim collection offscum, and can play the effect removing certain moisture in offscum, carries out after offscum is reclaimed again
Process, do not interfere with follow-up production operation；Automatically the design of wriggling stirring wheel, under offscum effect can automatic swing, to floating
Foam plays stirring action, it is to avoid block offscum recovery channel when offscum is excessive, and offscum recovery channel is type wide at the top and narrow at the bottom, can contract
The short concentration and settlement time, extend the concentrator normal work cycle, improve the service life of machine.
