Description
Technical field
The utility model relates to the equipment for separating liquid from solid of Mineral Processing Industry, particularly a kind of buried subsider underflow pipe preventing clogging up device.
Background technology
Current bauxite concentrate ore pulp adopts twice dehydration technique conventionally, and twice dehydration is respectively gravitational settling dehydration and filtering means dehydration, and wherein, what gravitational settling equipment adopted is buried subsider, and filter plant adopts plate and frame filter press.Concentrate pulp through gravity settling separation, obtains supernatant liquid and bottom high concentration sludge in subsider, and supernatant liquid is discharged from subsider top edge, is called overflow, and bottom high concentration sludge is discharged from subsider bottom, is called underflow.Underflow density is 30%-45%.Subsider underflow through filter press dehydration, can obtain the concentrate slurry product that moisture is qualified again, and its moisture is 14%.
The cell body top of above-mentioned buried subsider used is cylindrical shape, and diameter is 14m, and cylinder is high is 7m, and bottom is conical, and lower cone part is embedded in below ground.This buried subsider, compared with traditional ground type subsider, has building, advantage that construction cost is cheap.
Underflow in subsider need to pass through underflow pipe, provides power by filter press feeding pump, is pressed in filter press.Underflow pipe diameter is 300mm.The first half section of the underflow pipe of buried subsider is arranged on the cell body inside of subsider, and underflow materials must after underflow pipe flows obliquely, along continuous straight runs be mobile again, and therefore, the underflow pipe of buried subsider easily stops up.The reason of its obstruction is underflow materials excessive concentration in subsider, causes heavy knot, or surprisingly sneaks into bulk foreign material in subsider, and jam is in the mouth of pipe or pipe.After the underflow pipe of buried subsider stops up, underflow is discharge normally, in actual production, shows as, the drain hole of underflow pipe can not put underflow materials, filter press is material loading normally, and the material loading pressure decreased of filter press is zero (while normally operation, filter press material loading pressure is 0.4-0.8MPa).
Therefore, in the time of the underflow pipe generation obstruction accident of buried subsider, must be for a long time with high-pressure water pipe rinse, dredging, both difficulty, consuming time again, and need ore dressing plant to stop production completely, causes serious economic loss.
Summary of the invention
For above-mentioned situation, for overcoming prior art defect, the object of the utility model is to provide a kind of buried subsider underflow pipe preventing clogging up device, can effectively solve underflow pipe and easily stop up, and needs the cleaning that stops production, dredging difficulty, problem consuming time.
The technical scheme that the utility model solves is, comprise sedimentation cell body, shape anti-blocked sieving board, underflow pipe, recoil water pipe in groove, the groove water pipe that recoils outward, pipeline Special vibrator and underflow drain hole, feeding mouth is arranged at the top of sedimentation cell body, in sedimentation cell body, on the taper seat of bottom, there is the underflow pipe being tilted to, the lower end of underflow pipe extends to the bottom of sedimentation cell body, the upper end of underflow pipe extends to the upper end of taper seat, level is stretched out sedimentation cell body, the charging aperture top cover of underflow pipe lower end has the shape anti-blocked sieving board being fixed on sedimentation cell body, be placed in and on the underflow pipe on taper seat, be vertically communicated with recoil water pipe in many equidistant grooves, in groove, recoil water pipe protrudes upward sedimentation cell body, underflow pipe stretches out the groove water pipe that recoils outward on the external part of sedimentation cell body, the groove upper end of recoil water pipe in water pipe and groove of recoiling outward is all communicated with high-pressure water pipe, sedimentation cell body and groove recoil outward the pipe vibration device being contained on underflow pipe external part between water pipe, the end of underflow pipe external part is communicated with through feeding pump and filter press, on the underflow pipe that groove recoils between water pipe and feeding pump, there is a underflow drain hole outward.
The utility model not only effectively reduces the occurrence frequency of underflow pipe obstruction accident, meanwhile, and can be simply in the time that underflow pipe stops up, dredge quickly and efficiently.
