Description
Technical field
The utility model relates to a kind of hydrocyclone for coal slime classification of improvement, and it is a kind of hydrocyclone adding rinse water arrangement and aerating device, belongs to Mineral Processing Engineering technical field.
Background technology
Hydrocyclone is the capital equipment of coal preparation plant's coal slime multi-stage PCE, and hydrocyclone group plays a part to distribute and control separation of coarse slime system and floatation system pan feeding.Hydrocyclone because its structure is simple, easy to operate, production capacity is large, separative efficiency is high, floor space is little and without advantages such as drive disk assemblies, coal preparation plant is widely used, and obtains significant economic benefit.
But the hydrocyclone that at present coal preparation plant uses still also exists overflow low ash extract coal and runs the problem that thick, the thin mud of the high ash of underflow carries secretly.The achievement in research of forefathers is verified, and on hydrocyclone, set up rinse water arrangement or aerating device be solve overflow low ash extract coal to run the problem that thick, the thin mud of the high ash of underflow carries secretly, thus strengthen the feasible method of the coal slime grading effect of hydrocyclone.
Summary of the invention
The present invention relates to a kind of hydrocyclone for coal slime classification of improvement, it comprise feeding mouth (1), overfall (2), cyclone shell of column (3), cyclone cone section (4), rinse water ring (5), flushing water outlet (6), flushing water oral siphon (7), by-pass valve control A(8), flowmeter A(9), sleeve (10), gas tube (11), air inlet pipe (12), by-pass valve control B(13), flowmeter B(14), sand settling mouth (15), underflow opening (16).
The purpose of this utility model is to provide a kind of hydrocyclone for coal slime classification of improvement, aerating device is set up by the sand settling mouth place setting up rinse water arrangement and cyclone at cyclone shell of column foot, the hydrocyclone that can solve the use of current coal preparation plant still also exists the problem that overflow low ash extract coal runs slightly, the thin mud of the high ash of underflow is carried secretly, strengthens hydrocyclone to the grading effect of coal preparation plant's coal slime.
technical solution
A kind of hydrocyclone for coal slime classification of improvement, cyclone shell of column foot sets up rinse water arrangement, by the bath upwards that rinse water arrangement produces, the coal slime of cyclone shell of column is made to obtain classification, fine grain coal slime is subject to flushing water active force upwards and moves upward, thus the inward eddy entered in advance upwards, and the downward gravity that coarse granule high density coal slime is subject to and rotary centrifugal force are greater than flushing water active force upwards, and move downward, thus enter downward contour stealth in advance, which improves fine grained low-density coal slime enter the probability of overflow and reduce the probability that fine grained high density coal slime enters underflow, contribute to solving overflow low ash extract coal (fine grained low-density coal slime) like this to run thick (entering underflow), the problem that the thin mud (fine grained high density coal slime) of the high ash of underflow is carried secretly.Sand settling mouth place increases aerating device, microvesicle is produced by rushing aerating device, and fine grained is easily attached on microvesicle, to rise the inward eddy entered upwards with microvesicle, coarse granule is not easily attached on microvesicle, and then directly enter underflow with contour stealth and discharge cyclone with underflow opening, contribute to the problem that the thin mud (fine grained high density coal slime) of the high ash of solution underflow is carried secretly like this.The hydrocyclone that can solve the use of current coal preparation plant in conjunction with the above two kinds of device still also exists the problem that overflow low ash extract coal runs slightly, the thin mud of the high ash of underflow is carried secretly.

Detailed description of the invention
With reference to accompanying drawing 1 and accompanying drawing 2.
Rinse water arrangement mechanism: black water tangentially enters cyclone shell of column (3) from feeding mouth (1), spiralling is made downwards in cyclone, heavy phase medium is thrown toward wall by centrifugal inertial force effect, with downward contour stealth to the outlet of the cyclone section of cone (4), the dope of being discharged by bottom is called as underflow, liquid containing light substance then becomes the inward eddy of rising, and it is discharged from the overfall (2) at top, is called overflow.Set up rinse water arrangement at cyclone shell of column (3) foot, it comprise rinse water ring (5), flushing water outlet (6), flushing water oral siphon (7), by-pass valve control A(8), flowmeter A(9).By-pass valve control A(8 after cyclone work) open, flushing water is entered in the flushing water ring (5) in cyclone shell of column (3) by flushing water oral siphon (7), and the flowmeter A(9 on flushing water oral siphon (7)) be used for monitoring the amount of flushing water, after flushing water enters and rinses water ring (5), along rinse water ring (5) upper four upwards and the flushing water be arranged symmetrically with outlet (6) enter cyclone shell of column (3), wherein said four flushing waters outlet (6) are made up of pellicle, only allow passing through of water, do not allow passing through of particle.Upwards inflow cyclone shell of column (3) of flushing water can be allowed like this, stop defluent ore pulp in cyclone shell of column (3) to export (6) by flushing water and enter flushing water ring (5), thus prevent ore pulp to block the generation of flushing water outlet (6).By the bath upwards that rinse water arrangement produces, the coal slime of cyclone shell of column (3) is made to obtain classification, fine grain coal slime is subject to flushing water active force upwards and moves upward, thus the inward eddy entered in advance upwards, and the downward gravity that coarse granule high density coal slime is subject to and rotary centrifugal force are greater than flushing water active force upwards, and move downward, thus enter downward contour stealth in advance, which improves fine grained low-density coal slime enter the probability of overflow and reduce the probability that fine grained high density coal slime enters underflow, contribute to solving overflow low ash extract coal (fine grained low-density coal slime) like this to run thick (entering underflow), the problem that the thin mud (fine grained high density coal slime) of the high ash of underflow is carried secretly.
Aerating device mechanism: black water is entering sand settling mouth (15) place after cyclone cone section (4), sand settling mouth (15) is wrapped with sleeve (10), ring-type is had to wrap up the gas tube (11) of sand settling mouth (15) in sleeve (10), (11) have many micropores to described gas tube, sleeve (10) external air inlet pipe (12), (12) are connected with by-pass valve control B(13 to described air inlet pipe) and flowmeter B(14).After cyclone work, open by-pass valve control B(13), air enters sleeve (10) by air inlet pipe (12), and forms microvesicle by the micropore on gas tube (11), thus enter sand settling mouth (15), the flowmeter B(14 wherein in air inlet pipe (12)) be used for monitoring the inlet of air.Black water fine grained in sand settling mouth (15) is easily attached on microvesicle, to rise the inward eddy entered upwards with microvesicle, coarse granule is not easily attached on microvesicle, and then directly enter underflow with contour stealth and discharge cyclone with underflow opening, contribute to the problem that the thin mud (fine grained high density coal slime) of the high ash of solution underflow is carried secretly like this.
