Abstract
The invention relates to an overflow type enhanced tailing jet flow flotation device, which is provided with a flotation tank, wherein a slurry supply pipe, a discharge pipe and an ore concentrate discharge outlet are arranged in the flotation tank; an ore concentrate groove is formed on the outer side of the ore concentrate discharge outlet; and a spray turnover plate is arranged under the slurry supply pipe in the flotation tank. The overflow type enhanced tailing jet flow flotation device is characterized in that: a, a diversion enhanced emulsifying structure is additionally arranged above the spray turnover plate in the flotation tank and comprises a diversion plate arranged horizontally and an L-shaped baffle arranged opposite to the outer end of the diversion plate, the diversion plate, the L-shaped baffle and the spray turnover plate form a Z-shaped diversion channel; and b, a baffle is hung in the flotation tank to form an overflow channel, an overflow tank is arranged outside the flotation tank, an overflow pipe is assembled in the overflow tank, and the overflow tank is communicated with the overflow channel in the flotation tank. The overflow type enhanced tailing jet flow flotation device solves the problems of large impact, unstable liquid level, outward guniting, undesirable emulsifying effect and influence on recovery rate and ore concentrate grade in the conventional jet flow flotation machine, and is particularly suitable for recovering metal tailings with low content.
Description
(1) technical field: the present invention relates to preparation equipment, especially a kind of overflow-type enhanced type mine tailing jet flotation unit.
(2) background technology: the jet flotation machine that generally uses in the ore dressing plant at present includes float tank, and the top of float tank is provided with to the slurry pipe, and the bottom is provided with delivery pipe; Be furnished with valve, a upper lateral part of float tank has the concentrate floss hole, and the outside of concentrate floss hole is provided with concentrate hopper; Be provided with the magic flower plate over against the below of giving the slurry pipe in the float tank, its operation principle is: mortar is passed through the pressurization of high pressure sand pump, and through sending in the float tank for the slurry pipe; Impact magic flower plate foaming emulsification, reach the recovery purpose.This structure, because impulsive force is big, mortar is short in the float tank internal emulsification time, soup mixes not ideal enough with mortar, finally influence the rate of recovery and concentrate grade; Because impulsive force is big, mortar very easily from outside whitewashings such as concentrate floss holes, influences working environment simultaneously.On the other hand, for general ore dressing plant, for various reasons, its mortar output can not be stable, and is few for a long time during the mortar supply, therefore very easily causes the liquid level in the floating tank-washer unstable, thereby influences the rate of recovery and concentrate grade.
(3) summary of the invention: it is undesirable with mortar mixing and emulsifying effect that the object of the invention will solve existing jet flotation machine soup exactly, and the liquid level instability influences the problem of the rate of recovery and concentrate grade, and a kind of overflow-type enhanced type mine tailing jet flotation unit is provided.
Concrete scheme of the present invention is: improve to existing jetting type flotation device, it has float tank, and the top of float tank is provided with to the slurry pipe; The bottom is provided with delivery pipe; Be furnished with valve, a upper lateral part of float tank has the concentrate floss hole, and the outside of concentrate floss hole is provided with concentrate hopper; Be provided with the magic flower plate over against the below of giving the slurry pipe in the float tank; It is characterized in that: a. in float tank the magic flower plate above have additional water conservancy diversion and strengthen the emulsification structure, this structure includes the deflector of a horizontal arrangement and the L shaped baffle plate of a relative deflector outer end layout, said deflector and L shaped baffle plate and magic flower plate three constitute a zigzag honeycomb duct; B. the outstanding dividing plate of adorning in float tank forms overflow ducts, is furnished with spill box in the outside side relative with the concentrate floss hole of float tank and is fitted with overflow pipe, and said spill box is communicated with the interior overflow ducts of float tank.
In float tank, the outer end of magic flower plate is equipped with a downward oblique impact plate among the present invention, and there is spacing this oblique impact plate upper end with magic flower plate outer end, forms coarse sand and falls mouthful, and the lower end of oblique impact plate and the base plate of float tank and side plate all have spacing, formation last mortar runner.This structure mainly plays sand washing and sub-sand effect, can make on the one hand that the sand grains of (angle) portion is washed at the bottom of the float tank, prevents to pile up, and on the other hand, makes coarse sand in time fall to mouthful draining favourable concentrate flotation from coarse sand.
For enhancing productivity, satisfy the needs of different output, the delivery pipe that install the bottom of float tank described in the present invention is designed with the 2-8 root, is an arranged, on the every delivery pipe valve is housed.
For guaranteeing the overflow effect, the low side height of the base plate aspect ratio concentrate floss hole of spill box described in the present invention hangs down 150-300mm.
For the better variation that adapts to the mortar supply, regulate spillway discharge, between spill box and overflow ducts, gate is housed among the present invention.
The present invention strengthens the emulsification structure owing to set up water conservancy diversion, makes that soup is mixed with mortar fully, emulsification, foaming, has significantly improved the mine tailing rate of recovery and concentrate grade.The present invention has simultaneously also set up spill box, can make the variation of mortar supply no longer influence the stable of liquid level, thereby guarantee the stable of the flotation unit rate of recovery and concentrate grade.The present invention is simple in structure, emulsify well, and the automatic stabilisation liquid level, easy to operate, various mineral processing indexs can obtain stable the raising.In order to improve the rate of recovery, the present invention can two or more stacks use, the last mortar that a last delivery pipe and overflow pipe are emitted is sent into next and is carried out multistage flotation and get final product.
