Description
Technical field
The utility model relates to the technical field of coal separation, specially a kind of tailing recycling technique optimized product structure and
System is particularly suitable for the efficient recycling system of coal slime of tailing recycling technique.
Background technique
Three factory, the Inner Mongol Xin Kuang energy coal washing branch company belongs to mine type Oversized Coking Coal Cleaning Plant, which carries Great Wall San Kuang original
Coal enters task of washing, and designs 5,000,000 tons/year of washing ability.
For three factory's floatation system of the Inner Mongol Xin Kuang energy coal washing branch company in original design, flotation column need to install six, but consider
Construction fund was nervous at that time, only installed four during installation, remaining two are not installed.In actual production process, due to floating
Select system circulation amount larger, four flotation columns are not able to satisfy production requirement, and system is caused to run coal, and part cleaned coal enters filters pressing system
System is changed into coal slime, and final coal slime ash content is only 38% or so, and calorific value is up to 4000 kilocalories.In addition, concentration filter press need to have specially
The nurse of post machine, often adjusts, and personnel cost is also high；Filter press equipment appurtenance is more, and repair and maintenance amount is big, produces maintenance cost
It is high.
Therefore, it is necessary to be recycled cleaned coal again, increases profit for enterprise, reduce unnecessary loss, at black water
Reason system loading deficiency has seriously affected further increasing for coal separation yield, solves this problem and has become ought being engaged in for coal preparation plant
It is anxious.
Summary of the invention
The purpose of this utility model is optimized product structure to reduce coal slime calorific value, is recycled cleaned coal, is provided one kind
Based on the tailing recycling technique optimized product structure and system.To reduce coal slime calorific value, optimizes product structure, do not influencing
Under the premise of middle product of coal quality, tailing recycling technique is innovated, consideration, which uniformly mixes coal slime, is assigned to middle coal, by part coarse granule
Coal slime is converted into middle coal, finds product price difference, improves Business Economic Benefit, and in the program, partial concentration bottom of pond stream is driven into
In separation of coarse slime system TBS tailing high-frequency screen, realize that coal slime uniformly mixes the effect for being assigned to middle coal.
To achieve the above object, the utility model uses following technical scheme:
It is a kind of based on the tailing recycling technique optimized product structure, which is characterized in that partial concentration bottom of pond stream is squeezed into
Into separation of coarse slime system TBS tailing high-frequency screen, realizes that coal slime is uniformly mixed and be assigned to middle coal, convert part coarse granule coal slime to
Middle coal.
Further, the utility model based on the tailing recycling technique optimized product structure, specific steps are as follows: it is first
First, 200-13mm lump coal is sorted using dense-medium shallow-tank；Then using has two product dense medium cyclone masters of pressure to select 50-1.0mm again；So
1.0-0.25mm coarse slime is sorted using TBS sorting machine (hindered bed separator) afterwards；Then microbubble swirl column flotation-is used
0.25mm fine grained coal slime；Then using fast opening pressure filter dehydration recycling flotation concentrate；Finally using concentration+filters pressing recycling
Mode recycles flotation tailing, then partial concentration bottom of pond stream is driven into separation of coarse slime system TBS tailing high-frequency screen, realizes coal
Mud, which is uniformly mixed, is assigned to middle coal, converts middle coal for part coarse granule coal slime.
The technical characterstic based on the tailing recycling technique optimized product structure of the utility model is also:
The partial concentration bottom of pond stream, is the 1/3-1/2 of concentration basin underflow total amount.
The another object of the utility model is to provide a kind of based on the tailing recycling system optimized product structure, spy
Sign is, including sequentially connected dense-medium shallow-tank, have two product dense medium cyclones of pressure, TBS sorting machine, microbubble swirl flotation column,
Fast opening pressure filter, concentration filter press；It further include thickener underflow pump, which pumps one end and concentration filter press concentration
Pond is connected, and the other end of thickener underflow pump is connected to the high-frequency screen of TBS sorting machine.
Based on the characteristics of the tailing recycling system optimized product structure in addition, thickener underflow pump lift is high.
Further, thickener underflow pump leads to TBS sorting machine high-frequency screen using pipeline.
The utility model has the following beneficial effects:
The utility model based on the tailing recycling technique optimized product structure, partial concentration bottom of pond stream is driven into slightly
It in slime separation system TBS tailing high-frequency screen, realizes that coal slime uniformly mixes and is assigned to middle coal, converts part coarse granule coal slime to
Coal reduces coal slime calorific value, optimizes product structure, and innovates tailing recycling technique, improves Business Economic Benefit.
The utility model based on the tailing recycling system optimized product structure, the thickener underflow pump is dense by part
Contracting bottom of pond stream is driven into separation of coarse slime system TBS tailing high-frequency screen, realizes that coal slime uniformly mixes the effect for being assigned to middle coal.
High frequency shale shaker is effective equipment of Slime sizing & dewatering, it and filter press cooperation can solve filter press excess load
Problem can reduce investment and the production cost of slurry circulating system.Its feature fine grained first is that the upper filtering layer of dependence sieve shuts off
With bed of material extrusion dehydration, realize that the big screen slot that common vibrating screen can not be completed recycles fine grain work；Second is that having vibration
The feature that intensity is big, working frequency is high, screening efficiency are up to 70% or more.Due to screening efficiency height, it is negative that circulation can be greatly lowered
Qualified grain size content in lotus and oversize.
In addition, high-frequency screen only need to carry out inspection after adjusting, it is not required to set dedicated driver, reduces personnel cost, it is high
It is small that maintenance is repaired in frequency screening, puts into low.
In short, the system of the utility model, equipment operation is simple, and smooth running is reliable, and processing performance is good, produces thing
Therefore it is few.
The technology of the utility model works well it has been proved by practice that operating is reliable, can be negative with partial reduction coal slime filter press
Lotus, recycling coarse slime are compared as follows using the condition of production before and after high-frequency screen.
Table 1 is using preceding to Contrast on effect table
As can be seen from Table 1: high-frequency screen using effect is good, and treating capacity can be significantly increased with feed thickness raising, and
Product moisture is low, can play the role of recycling coarse slime completely.
