Abstract
The invention discloses a high-speed disc type dehydrator, and belongs to the field of preparation equipment. The high-speed disc type dehydrator comprises a motor, a drum cover shell, a transmission device and a drum component, wherein the drum component is positioned in the drum cover shell, and comprises a main shaft, a working disc component and a drum; the main shaft is vertically inserted in the vertical center position of the drum, and is sealed and fixedly connected with the lower end of the drum; the upper end of the drum is an opening; the working disc component is mounted in the drum; and the motor is connected with the main shaft through the transmission device. Pulp with a concentration of 5-7% can be concentrated and dehydrated by the equipment to change the concentration about 40%. In particular, after fine particles about -10 microns are treated by the equipment, overflow solid contents thereof are lower than 0.5%, so that such advantages as obvious concentration effect, high production efficiency and small floor area are achieved; and polished fine tailings can be concentrated before a floatation section, so that the tailing transport cost is reduced, and the water recycling rate is improved.
Description
Technical field
The invention belongs to and belong to preparation equipment field, be specially a kind of high speed disc dewaterer.
Background technology
In wet-milling plant, dressing product (concentrate, chats and mine tailing) in most cases all exists with ore pulp form.For the ease of processing further and smelting, fully recycle water resource, product moisture content all be there are certain requirements.Milltailings, for the ease of carrying and stacking and utilize backwater, mine tailing also needs to carry out necessary thickening.In dressing Production Process, subsequent job also has concentration requirement to a upper operation product sometimes, and therefore dressing product dehydration is absolutely necessary production link.
The pollution sources in ore dressing plant have waste water,waste gas and industrial residue, wherein particularly outstanding with Wastewater Pollutant.Beneficiation reagent, cumulative toxicity material (as mercury, chromium, cadmium and heavy metal etc.), make total environmental quality situation aggravate.Cyanide efflux wastewater will become the primary pollution source of water body, and the discharge of waste gas forms directly harm to crowd, biota, and the heap of waste residue abandons the deterioration of the ecological environment caused.
Ore particle is in dehydration concentration process, and ore particle size is very large on sinking speed impact.Coarse grain (0.5 ~ 0.07mm) deposition is very fast, and particulate, particularly microfine (-10 microns) due to its Action of Gravity Field by Brownian movement and surface tension balance, and pulp viscosity is also large, so be in stable dispersity for a long time, accelerate the sedimentation of these subparticles, the method adopted at present has and adds flocculant and heat.Common equipment has: common thickener, lamella thickener and high-efficiency concentrator.But production efficiency is lower, floor space is large, invest high, and swash plate is yielding, aging, many impacts such as contaminated environment.
Summary of the invention
The object of this invention is to provide a kind of concentrated effect obviously, production efficiency is higher, a kind of high speed disc dewaterer that floor space is less.
The technical scheme realizing above-mentioned purpose is: a kind of high speed disc dewaterer, is characterized in that: comprise motor, rotary drum case, transmission device and drum assembly; Described drum assembly is placed in rotary drum case, drum assembly comprises main shaft, scratch diskette assembly and rotary drum, and main shaft is vertically placed through the vertical centred position of rotary drum, and the lower end of main shaft and rotary drum is sealedly and fixedly connected, the upper end of rotary drum is opening, and described scratch diskette assembly is arranged in rotary drum; Described motor is connected with main shaft by transmission device;
Scratch diskette assembly comprises scratch diskette support, scratch diskette gland and some taper type scratch diskettes, described scratch diskette support comprises top linkage section and lower taper section, described scratch diskette support casing is contained in rotary drum, the inwall of scratch diskette support is provided with supporting rib, scratch diskette support is supported on the bottom of rotary drum by the supporting rib of bottom, the taper type scratch diskette of described some successively stacked on top of one another is added in the lower taper section of scratch diskette support, every two adjacent taper type scratch diskettes are provided with equidistant gap, described scratch diskette gland is sleeved on the taper type scratch diskette of the superiors, the lower end of scratch diskette gland and the upper port of rotary drum are sealedly and fixedly connected,
Described main shaft is equipped with feed pipe, described feed pipe passes the intracavity inter-connection of rotary drum case and drum assembly and rotary drum from the top down successively, gap is left as overfall between the upper end of described scratch diskette support and the upper end of scratch diskette gland, the bottom of rotary drum is provided with spigot, described rotary drum case is provided with superposed spill cavity and is positioned at the sand setting chamber of bottom, the lower end of the spill cavity of described rotary drum case is provided with the overflow be connected with described overfall and exports, the lower end in the sand setting chamber of described rotary drum case is provided with the sand setting be connected with described spigot and exports.
The present invention utilizes Stokes' law in centrifugal force field, utilize centrifugal force field to ore particle particularly microfine (-10 microns) carry out Accelerated subsidence, thickening is carried out to magma; Ore pulp enters in drum assembly through feed pipe, subparticle is deposited to the up one-tenth sand setting of taper type scratch diskette under the high speed centrifugation power effect of disk type dehydrator, sand setting slides along scratch diskette inner surface and departs from taper type scratch diskette to spigot place in rotary drum and move discharge, enters flotation operation.As the liquid phase clarified then under the internal pressure difference effect of drum assembly, discharge from the overfall of drum assembly.
Ore pulp by the process of this equipment, can be by concentration 5 ~ 7% ore pulp through thickening to concentration about 40%.Particularly for the microfine of-10 microns, compare with miscellaneous equipment, after process of the present invention, overflow is admittedly containing thing < 0.5%, concentrated effect is obvious, the advantages such as production efficiency is high, and floor space is little, and can concentrate the fine mine tailing of dishing out before flotation workshop section, reduce the recovery utilization rate of Tailings transportation expense and raising water.
