Description
Technical field
The present invention relates to a kind of liquid-solid separation screening device again, especially relate to a kind of ore dressing industry tailings dewatering that is used for and do liquid-solid separation that row or iron ore dehydration do row and isolate two kinds of different products of granularity screening device again.
Background technology
Mine tailing in the mining industry is handled and never is well solved, and the mine tailing in the traditional handicraft contains large quantity of moisture, need build the mine tailing storehouse, takies tract, causes soil erosion, channel filling, water pollution, environmental destruction.
Traditional tailing dry drainage technique is that the mine tailing slip is at first centrifugalized through cyclone; Obtaining the bigger slip of underflow density after the separation filters through rotary drum vacuum filter again; Centrifugalize the last overflow liquid process concentrator sedimentation separation that obtains through cyclone; The underflow that the concentration that obtains after the separation is bigger filters through rotary drum vacuum filter again, obtains the dried mine tailing of concentration 80-90% after being filtered by rotary drum vacuum filter, obtains filtrating simultaneously; Filtrating and the last overflow liquid that obtains via the concentrator sedimentation separation after the settling tank sedimentation, the clear liquid recycling.The rotary drum vacuum filter that uses in the dried drainage technique of traditional tailings dewatering mainly comprises horizontal rotary drum and distribution plate; Be equipped with filter cloth on the bulging face of horizontal rotary drum; Distribution plate is connected with malleation generator, water ring vacuum pump and drain pump successively, and the other end of drain pump links to each other with said distribution plate through pipeline, and filter cloth is that nylon cloth is as medium; Because nylon cloth is as medium; Gas permeability is bad, so power consumption is very big during the mine tailing slurry dewatering, and has to a kind of product when using nylon cloth to filter as the rotary drum vacuum filter of medium.In addition; Rotary drum vacuum filter requires the pan feeding concentration of mine tailing slurry to be not less than 60%; Because of the mine tailing slurry concentration usually is lower than 60%, therefore before the filter dehydration, need add a concentrator and the mine tailing slurry is carried out dehydration in early stage concentrate, the increase concentrator not only need take bigger land use area; And increased bigger equipment investment, cause the high deficiency of equipment operating cost.
Summary of the invention
The technical problem that the present invention will solve provides that a kind of liquid-solid separating rate is fast, good separating effect, consumed power is few, simple in structure, volume is little and the liquid-solid separation that can isolate two kinds of different material products of granule size screening device again.
For solving the problems of the technologies described above; A kind of liquid-solid separation of the present invention is screening device again, comprises feed box and rotary drum vacuum filter, and this rotary drum vacuum filter comprises horizontal rotary drum and distribution plate; Be equipped with filter cloth on the bulging face of horizontal rotary drum; Distribution plate is connected with malleation generator, water ring vacuum pump and drain pump successively, and the other end of drain pump links to each other with said distribution plate through pipeline, and the bottom of said rotary drum vacuum filter is provided with discharging opening; The filter cloth of laying on the said bulging face is provided with efficient strong magnet for first metal screen of mesh size can be set according to raw meal particle size in advance in the said horizontal rotary drum; Be laid with a plurality of circles in the said drain pump and lack the shape deflection plate; The breach direction that scarce shape deflection plate of each circle and adjacent circle lack the shape deflection plate is opposite; The drain pump roof that each circle lacks the front upper place of shape deflection plate is provided with the automatic control solenoid valve that is used to wash these deflection plates, and the air entry of said drain pump is provided with second metal screen that the mesh size can be set according to raw meal particle size in advance.
As further improvement of the present invention, described feed box is provided with by electromagnetic vibrator and can the vibrating plug that the 3rd big or small metal screen of mesh constitutes be set in advance according to raw meal particle size, and the lower end of this feed box is provided with discharging opening.
Further improve as of the present invention; Pipeline between said drain pump and the distribution plate is connected with the labyrinth type baffler; Be evenly equipped with a plurality of labyrinths circle in this labyrinth type baffler and lack the shape deflection plate; The breach direction that round scarce shape deflection plate in each labyrinth and adjacent labyrinth circle lack the shape deflection plate is opposite, and the roof of the labyrinth type baffler of the front upper place of the scarce shape deflection plate of each labyrinth circle is provided with and is used to wash the round automatic control solenoid valve that lacks the shape deflection plate in these labyrinths; The bottom of said labyrinth type baffler is provided with automatic ore discharge valve.
The liquid-solid separation of employing said structure is screening device again; Because the nylon cloth filter cloth that uses in traditional rotary drum vacuum filter is improved to the metal screen that the mesh size can be set according to raw meal particle size in advance, make gas permeability stronger 4～5 times than traditional product, rate of air sucked in required has improved 30～40%; Saves energy 20～30%; The bed of material increases thickness 20～30%, and output improves 30～40%, and liquid-solid separation rate reaches more than 90～95%.The purpose of having set up deflection plate in the drain pump is to make material can sink to discharge gate to greatest extent through baffling repeatedly to discharge, and the purpose of the metal screen of air entry setting be with rotary drum vacuum filter in the metal screen that uses cooperate.Because the nylon filter cloth in the rotary drum of rotary drum vacuum filter is improved to metal screen; The percent of pass of material is improved greatly; Therefore the material in the drain pump also has largely and increases; Set up metal screen at air entry and can prevent effectively that suction owing to water ring vacuum pump from get in this water ring vacuum pump material and damaging water ring vacuum pump, water ring vacuum pump is had good protective effect.The discharge gate of drain pump bottom obtains the thinner a kind of product of raw meal particle size.
In feed box, be provided with by electromagnetic vibrator with can the vibrating plug that the metal screen of mesh size constitutes be set in advance according to raw meal particle size; Can concentrate and filter out the thinner a kind of product of a kind of granularity to the slurry in the feed box; The thinner product of granularity is discharged by the feed box discharge gate; To the concentrating of slurry, the concentration of slurry is reached more than 60% through the vibrating plug.
