Abstract
The utility model discloses a kind of cleaned coal to starch concentration pre-dehydration device, thickener including taper, the concentration trench bottom are provided with discharge gate, plug are provided with the discharge gate, at least one filter bores are offered on the thickener, filter cloth is provided with the filter bores.The cleaned coal slurry concentration pre-dehydration device of the structure, has the advantages of simple in construction, to save production cost, cleaned coal enrichment factor height and save reagent cost.
Description
Technical field
It the utility model is related to a kind of cleaned coal slurry concentration pre-dehydration device.
Background technology
As coal in China exploitation yield, mining mechanization degree and raw coal enter to wash the increase of rate, fine fraction coal slurry content
Greatly improve, accounted for and washed more than the 20% of raw coal amount.Bed for Fine Coal mainly uses floatation process recovery section cleaned coal, flotation at present
Cleaned coal that technique productions go out starch the mass concentration of the cleaned coal slurry that general concentration is relatively low, and different floatation process are produced typically 5~
25%, this coal slurry, which must carry out dewater treatment, can just obtain final head coal product.The concentration that cleaned coal slurry enters before dehydration procedure
Just, its dewatering efficiency of extreme influence.Concentration is higher, and dewatering efficiency is higher.
Existing coal slurry method for concentration and equipment make coal slurry flocculation heavy mainly using taper concentration basin addition flocculation medicament
Drop, supernatant overflow go out concentration basin, so as to realize concentration.Concentration of this method and apparatus for tail coal is largely effective, but uses
Two large problems but be present when cleaned coal：1. the addition of flocculation medicament will make final head coal product ash content rise 1~2%, greatly drop
Low cleaned coal quality；2. cleaned coal foam is generally difficult to eliminate, ullage is gathered in, causes cleaned coal slurry overflow entrainment considerable part essence
Coal, overflow clear liquid was both polluted, has caused cleaned coal to lose again.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of cleaned coal slurry concentration pre-dehydration device, makes it have structure
Simply, the advantages of saving high production cost, cleaned coal enrichment factor and saving reagent cost.
The utility model is solved the above problems by following technological means：A kind of cleaned coal slurry concentration pre-dehydration device, including
The thickener of taper, the concentration trench bottom is provided with discharge gate, at least one filter bores is offered on the thickener, described
Filter cloth is provided with filter bores.
Further, it is provided with the skeleton being fixedly connected with thickener on the outside of the filter cloth.
Further, the skeleton is steel wire or grid.
Further, the filter bores are distributed in the bottom of thickener.
Further, the filter bores are evenly distributed on the bottom of thickener.
The beneficial effects of the utility model：
1. the device structure is simple, cost of investment is low, concentration process without adding concentration medicament, greatly save medicament into
This.
2. during charging, while charging, while being filtered by filter bores, material natural subsidence, the stillness of night not overflow, but passes through
Filter bores discharge cell body carries out concentration predrainage, substantially increases the smart coal-water fluid concentration in thickener, is advantageous to improve concentration effect
Rate and effect.
3. being provided with skeleton on the outside of the filter cloth, skeleton can not only protect filter cloth, and can increase at filter bores
Mechanical strength.
4. by filter-cloth filtering, the filtrate cleaner than conventional outflow water can be obtained, has greatly prevented cleaned coal loss.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic cross-section of filter bores；
Fig. 3 is the structural representation of skeleton.
Embodiment
The utility model is described in detail below with reference to accompanying drawing, as Figure 1-3：The utility model provides one
Kind cleaned coal slurry concentration pre-dehydration device, includes the thickener 1 of taper, and the concentration trench bottom is provided with discharge gate 2, the concentration
At least one filter bores 3 are offered on groove, it is preferable that the filter bores are evenly distributed on the bottom of thickener, the filter bores
Place is provided with filter cloth 4.Cleaned coal slurry is concentrated and the detailed process of predrainage is：Floatation clean coal slurry enters in thickener, side
Charging, side natural subsidence, clear liquid not overflow, but discharge thickener by filter bores and carry out concentration predrainage, after concentration
Cleaned coal starch dehydration procedure be discharged into by discharge gate.Using the concentration pre-dehydration device of the structure, have the following advantages that：
1. the device structure is simple, cost of investment is low, concentration process without adding concentration medicament, greatly save medicament into
This.
2. during charging, while charging, while being filtered by filter bores, material natural subsidence, the stillness of night not overflow, but passes through
Filter bores discharge cell body carries out concentration predrainage, substantially increases the smart coal-water fluid concentration in thickener, is advantageous to improve concentration effect
Rate and effect, the cleaned coal slurry that mass concentration is 5~25% can be concentrated into more than 35%.
3. by filter-cloth filtering, the filtrate cleaner than conventional outflow water can be obtained, has greatly prevented cleaned coal loss.
As the further improvement to above-mentioned technical proposal, the bone being fixedly connected with thickener is provided with the outside of the filter cloth
Frame 5, the skeleton are steel wire or grid.Skeleton can not only protect filter cloth, and it is strong to increase the machinery at filter bores
Degree.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
