Description
Technical field
The utility model relates to a kind of preparation equipment, specifically relates to a kind of floatation equipment.
Background technology
Known flotation device is mineral manufacture field a kind of floatation equipment commonly used, is widely used in the separation operation of non-ferrous metal, ferrous metal, rare precious metal and coal, chemical industry mineral etc.Flotation device of a great variety; Difference mainly shows aspects such as inflation mode and stirring structure; Using maximum sorting techniques at present is by the different of inflation and alr mode flotation device to be divided into two big types, and promptly agitation impeller flotator and pneumatic flotation cell (thank to the Guangyuan, " mineral dressing "; Publishing house of China Mining University, August calendar year 2001).Agitation impeller flotator abbreviates flotation device usually as, and pneumatic flotation cell is most typical to be exactly flotation column.
Agitation impeller flotator is owing to its strong stirring action has stronger turbulence level; Ore pulp is uniformly dispersed; Can the air that suck or be pressed into be cut apart simultaneously and be broken into tiny bubble, so the general inflation of agitation impeller flotator is good, and bubble is uniformly dispersed.The main region that bubble contacts with ore particle is distributed in the high-shear region around the impeller; Mineralization is strong; So flotation device is to the comparatively effective (Sun Shiyuan of the bigger mineral floating of proportions such as coarse grain flotation and metalliferous mineral; " up-to-date Chinese preparation equipment handbook, Beijing Machinery Industry publishing house, in October, 2006).But stronger turbulence level is unfavorable for the mineral laden bubble come-up in the cell body, and because flotation device body height is less, mine tailing mouth position is higher; Good mineral of a large amount of floatabilities and less mineral laden bubble are discharged from the mine tailing mouth, ore pulp short circuit and purpose mineral channelling phenomenon occur, single groove efficiency of separation is descended; So traditional flotation device generally adopts the mode of multiple-grooved logotype, flotation repeatedly is though can obtain the separating effect of expection like this; But repeat sorting and increased amount of equipment; Increased the input of founding the factory, and the power consumption increase, the operation cost of selecting factory increased.
In floatation equipment, the mineralization degree of bubble, bubble all are key factor (king's money, " the floating separation technology " that realization separates with the isolating environment of ore pulp; Metallurgical industry publishing house, in October, 2006), the turbulence level of flotation device is bigger; The isolating environment of flotation column is better comparatively speaking owing to there is not an agitating device, the flotation column turbulence level a little less than; The isolating environment of approximate static state is provided, has helped the layering that separates of mineral laden bubble and ore pulp, and form stable froth bed.Flotation column belongs to the column-type floatation machine, is a kind of shallow/deep groove type pneumatic flotation cell, and ore pulp feeds from flotation column top usually, in dropping process, with reverse contact of bubble of rising, in the adverse current collision, realizes mineralising.But flotation column is strengthened mineralization process and inner loop reinforcement recovery link owing to lack the stirring of flotation device; Mineralization intensity relatively a little less than; Increase the contact probability that the high form of post increases ore particle and bubble so flotation column generally adopts, increase the length in mineralising zone, the height of column of traditional flotation column is generally about 10 meters; But the rate of recovery still is lower than flotation device, and particularly unfavorable to the recovery of the bigger metalliferous mineral of coarse grain and proportion.To this problem, many scholars once designed some novel flotation columns, had strengthened the mineralising effect to a certain extent, but had not all solved root problem, and flotation column rate of recovery in the flotation of metalliferous mineral still is not so good as flotation device at present.
The discharge of concentrate is last link that realizes FLOTATION SEPARATION; On separate mode; Flotation device adopts the form of edge scraper plate to scrape bubble more, and flotation column adopts automatic Overruning more, and these separate modes all exist foam to accumulate in a large number, the time of staying is long when wait scrapes, froth bed horizontal transfer stroke big, have shortcoming such as dead angle; Not to the froth concentrate active collection, can think that the concentrate of extensive style is discharged mode.In addition, flotation device is because stronger action of turbulent flow is carried the spray equipment that comparatively serious, traditional flotation device does not clean froth concentrate secretly, so concentrate grade is relatively poor in the froth concentrate.
