Description
Technical field
The present invention relates to ultrasonic wave deslimings before coal slime desliming field before coal preparation plant's flotation more particularly to a kind of coal slime flotation to fill
It sets.
Background technique
Current most of coal washerys are hm coal preparation plants, especially coking coal coal washery, in washing using this technique
In coal works, head coal product is not the cleaned coal that single gravity separation technology washing comes out, some floatation clean coal is the two
Mixed product, due to physical property, washing production technology and screening installation of coal etc., floatation clean coal ash content one
As be higher than required head coal product ash content, in order to keep floatation clean coal and the mixed head coal product ash content of dense medium washing cleaned coal full
Sufficient customer requirement, it usually needs reduce 1-2% again on the basis of ash content of the gravity treatment cleans ash required by head coal product, make weight
Selecting cleaned coal is floatation clean coal " back ash ", has seriously affected the yield and ash content quality requirement of head coal product, to coal washery cause compared with
Huge economic loss.
Coal is a kind of non-homogeneity, is made of organic matter and inorganic matter, accounts for major part in inorganic matter mineral, packet
Kaolinite, montmorillonite, quartz etc. are included, and is existed with coal association, in recent years, adopts and transports as coal mine machinery melts, minerals
Removing becomes subparticle from coal under the effect of external force with coal, and with the continuous propulsion of mechanical mining, cash in raw coal
Stone amount is significantly increased, and Separate Fine-grained Minerals granule content is with increase, and high ash thin mud also increases as in coal slime.And enter flotation link
Black water in particle less than 0.5mm account for major part, and coal particle surface adheres to various high ash Separate Fine-grained Minerals, high ash
Separate Fine-grained Minerals pollute cleaned coal by thin mud entrainment and the cover, to reduce flotation efficiency and increase floatation clean coal ash content, coal particle
The high ash thin mud content of surface attachment is higher, and it is more serious to influence floatation clean coal ash content, causes coal slime flotation constantly to deteriorate, floats
Selecting that tail coal ash content is too low, the loss of coarse granule cleaned coal is big, cleans ash is high, and it is contaminated serious, increase flotation device processing pressure etc. and asks
Topic.If can will enter flotation coal slime carry out desliming process in advance, i.e., by a part of high ash thin mud microparticle of coal slime not into
It is dispelled before entering flotation device, the product quality of flotation efficiency and floatation clean coal can be greatly improved, mitigated at flotation device
Manage pressure etc..
Summary of the invention
The present invention in order to overcome the above-mentioned deficiencies of the prior art, provides ultrasonic wave desliming device before a kind of coal slime flotation,
Reliable and stable, flexible adjustment of the invention, it is easy to use.
To achieve the above object, present invention employs following technical measures:
Ultrasonic wave desliming device before a kind of coal slime flotation, it is characterised in that: including by desliming pond, desliming pond discharge nozzle, overflow
Chute, pump, desliming pond feed pipe, concentrate discharge nozzle, charging cover board, energy converter, supersonic generator composition；Pan feeding coal before flotation
Muddy water enters the desliming pond through the charging cover board by desliming pond feed pipe, and the desliming pond surrounding pool wall installs institute
Energy converter is stated, the energy converter connects the supersonic generator, overflow launder described in the top layout of the desliming pond, the desliming
The bottom in pond connects desliming pond discharge nozzle, and desliming pond discharge nozzle connects the feed inlet of the pump, the discharging of the pump
Mouth connects the concentrate discharge nozzle, and the concentrate discharge nozzle connects floatation process link, the floatation feed coal slime after desliming
Into floatation system；The energy converter connects the supersonic generator, and ultrasonic wave passes after supersonic generator generation
It is defeated to arrive the energy converter, it is transmitted in the desliming pond after converting electric energy to mechanical energy, and the coal particle in the desliming pond
Near zone generates high-frequency mechanical vibration and high-speed micro-jet, under high-frequency mechanical vibration and high-speed micro-jet effect, coal particle
The clay mineral of surface attachment is detached from coal particle surface and enters in black water, and as coal slime water flow ascends into overflow launder,
And coal particle becomes concentrate because self gravitation effect sinks to desliming bottom of pond portion, realizes the effect of coal slime desliming before flotation.
It is described charging cover board be located at the desliming pond feed pipe outlet underface, the charging cover board pass through fixed link and
Desliming pond feed pipe is reliably fixed together；Due in pipeline under the action of quick inertial flow, pan feeding coal before flotation
Muddy water can quickly be gushed out from the outlet of desliming pond feed pipe, impact on the charging cover board, the black water quickly flowed
It flows and is slowly spread around under the blocking of the charging cover board, in the high-frequency mechanical vibration and high-speed micro-jet that ultrasonic wave generates
Under the action of, the clay mineral of coal particle surface attachment is detached from coal particle and enters in the overflow water water flow of rising, into described
In overflow launder, become the tailing of ultrasonic wave desliming, coal particle sinks to the desliming bottom of pond portion in self gravitation effect, becomes super
The concentrate of sound wave desliming；If the black water quickly flowed in pipeline can be quickly from the desliming pond without the charging cover board
Feed pipe outlet is gone out, and forms violent turbulent flow in the desliming pond, causes coal particle that can not normally sink and be detached from coal
The clay mineral of particle surface can not enter the overflow launder with the overflow water water flow of rising.
