Description
Technical field
This utility model relates to coal industry, is specifically related to the dehydration equipment of a kind of fine slime.
Background technology
Pressing filter is to be dehydrated to floatation clean coal in the effect of coal preparation plant.Due to flotation material size 0.25mm with
Under, the granularity of material is meticulous, floatation clean coal bad hydraulic permeability, and sucrose extraction is low, and the disposal ability of pressing filter is substantially reduced, filter cake
Thin, moisture is up to 25%.In process of production, owing to the disposal ability of pressing filter is low, add press-in material bucket often full, impact
Washing produces.And the load making slurry circulating system increases the weight of.
Summary of the invention
The purpose of this utility model provides the dehydration equipment of a kind of fine slime, mainly solves in prior art due to flotation
Raw meal particle size is meticulous, and when causing pressing filter to be dehydrated, bad hydraulic permeability, sucrose extraction is low, yields poorly, the problem that moisture is big.
In order to achieve the above object, this utility model is by the following technical solutions:
The dehydration equipment of a kind of fine slime, this equipment includes hydraulic classification swirler group, described hydraulic classification swirler

Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Seeing Fig. 1, a kind of fine slime dehydration equipment of the present invention includes that hydraulic classification swirler group, TBS sort
The equipment such as machine, sieve bend, centrifuge, flotation device, pressing filter, wherein, cleaned coal magnetic tailing is beaten to hydraulic classiciation rotation through pump
Carry out classification in stream device group, after classification, obtain overflow product and underflow product.Gained underflow product passes through hydraulic classification swirler
Underflow opening stream enter in TBS separator and again sort, obtain coarse-fine coal and tail coal, the coarse-fine coal of gained enters through sieve bend
Row processed, obtains oversize and siftage, and gained oversize is dehydrated through horizontal type scraper centrifuger, finally gives thick
Head coal product.
The overflow product of hydraulic classification swirler group gained enters flotation device by overfall and sorts, and obtains floating essence bubble
Foam and mine tailing, gained floating essence foam is in flotation device in concentrate hopper.In order to change gained floating the essence granularmetric composition of foam, raising
Its concentration, is connected to one on the pipeline that hydraulic classification swirler group leads to TBS separator and mixes extra heavy pipe, and this is mixed extra heavy pipe and is provided with valve
Door, during valve closing, original technique runs well, and when valve is opened, hydraulic classification swirler component selects the underflow product of gained
Mix in extra heavy pipe is sent to flotation device concentrate hopper by this and floating essence foams mix, obtain mixing floating essence foam.
Concentrate to pressurization storehouse is beaten through feed pump in the mixing obtained floating essence foam is sent to pressing filter feed barrel
Groove, processes through pressure filtration dewatering, obtains qualified floatation clean coal product.
