Description

A kind of thickener charging gear
Technical field
The present invention relates to a kind of thickener charging gear in the large-scale solid-liquid separation dehydration equipment industry, especially make thickener reach the charging gear of uniform distribution and discharging.
Background technology
At present, general large-scale solid-liquid separation dehydration equipment is thickener in factories such as ore dressing plant, coal preparation plant, thermal power plant, municipal sewage plant and water supply plant.It is to make to feed slip and be arranged into uniformly in the circumference of thickener pond body that the charging gear of thickener mainly acts on, and carries out gravitational settling, and flocculant with feed mixing of slip etc.But existing thickener charging gear substantially just is provided with stabilizing feed well, and the speed that feeds ore pulp is reduced, and does not have the ability of uniform distribution and discharging substantially, and the immixture of flocculant and slip is also extremely undesirable.
Because traditional thickener charging gear does not have booster action to the mixing of flocculant and material, normal flocculant addition does not reach the result of use of expection far away, can only increase its addition, has so just strengthened production cost.
Distributed pole was inhomogeneous after traditional thickener charging gear usually caused solid particles sediment in the slip at the bottom of the pond, local pond initial bed thickness reaches 1.5 ~ 3 times of normal operating conditions, so just make thickener scrape mud equipment local pressure and increase many times, thickener works long hours under the periodicity hard service, and the as easy as rolling off a log mud-scraping apparatus of equipment and the drive unit of making is impaired.Shortened the service life of thickener greatly.After thickener damaged, the ordinary production work of factories such as ore dressing plant, coal preparation plant just was forced to stop, and can cause the tremendous economic loss to country.Therefore, develop a kind of thickener is new problem anxious to be solved with charging gear always.。
Summary of the invention
The object of the present invention is to provide a kind of thickener charging gear, this structure is compared with traditional thickener charging gear, and cloth is even, and discharging is even, the flocculant good mixing effect.
The object of the present invention is achieved like this: a kind of thickener charging gear, comprise charging aperture, stabilizing feed well, material-blocking plate, the cloth base plate, the umbrella shape distributing device, blocking cylinder, drain separator, the sidewall of stabilizing feed well is provided with charging aperture, the sidewall of charging aperture and stabilizing feed well is welded to connect, be welded with the cloth base plate with the charging aperture correspondence position in the stabilizing feed well, be welded with material-blocking plate between the cloth base plate, the stabilizing feed well bosom is provided with blocking cylinder, the blocking cylinder bottom is connected with the drain separator bolt, charging aperture and stabilizing feed well, cloth base plate and material-blocking plate are integrally welded, and stabilizing feed well below is connected with bolt with the umbrella shape distributing device with connecting rod; Stabilizing feed well top uses bolt to be connected transfixion when this part is worked at thickener with the thickener fixed part; Shelves barrel and drain separator use bolt to link into an integrated entity, and rotate with thickener; At regular intervals between umbrella shape distributing device and the drain separator, be used for cloth and discharging; The current stabilization barrel is provided with vertical material-blocking plate; The operation principle of this device is, use the centrifugal sedimentation principle, tangential pan feeding, it is tentatively concentrated to carry out ore pulp in the current stabilization bucket, structural device is more scientific and reasonable, the slip that feeds is by the vertical material-blocking plate on the current stabilization barrel, promote air discharging and dissipation excess energy effectively, the structure of current stabilization bucket has promoted the hybrid motion of flow of slurry, make ore pulp and flocculant be able to fully mix, because this design of current stabilization bucket, feasible solid flow by charging gear is consistent, and the ore pulp short circuit phenomenon is reduced to minimum degree, and the shunting action of umbrella shape distributing device and drain separator can make and the well-mixed ore pulp control of flocculant motion within limits, further condense into the bulky grain floc sedimentation, and the ore pulp that concentration is improved directly fed the settled layer of thickener, and promote thickening efficiency greatly, improve dewatering process flow and overflow clarity and underflow density.
Main points of the present invention are its structure and operation principle.Its operation principle is, use the centrifugal sedimentation principle, tangential pan feeding, it is tentatively concentrated to carry out ore pulp in the current stabilization bucket, structural device is more scientific and reasonable, the slip that feeds is by the vertical material-blocking plate on the current stabilization barrel, promote air discharging and dissipation excess energy effectively, the structure of current stabilization bucket has promoted the hybrid motion of flow of slurry, make ore pulp and flocculant be able to fully mix, because this design of current stabilization bucket, feasible solid flow by charging gear is consistent, and the ore pulp short circuit phenomenon is reduced to minimum degree, and the shunting action of umbrella shape distributing device and drain separator can make and the well-mixed ore pulp control of flocculant motion within limits, further condense into the bulky grain floc sedimentation, and the ore pulp that concentration is improved directly fed the settled layer of thickener, and promote thickening efficiency greatly, improve dewatering process flow and overflow clarity and underflow density.
A kind of thickener with charging gear compared with prior art, have the feed-type advanced person, structural device is more scientific and reasonable, cloth is even, discharging is even, the flocculant good mixing effect, promote thickening efficiency, improve dewatering process flow and advantages such as overflow clarity and underflow density, will be widely used in the large-scale solid-liquid separation dehydration equipment industry.
