Abstract
The utility model discloses a flotation column foam collection device which comprises a flotation column (1); a through hole with an upper opening and a lower opening is formed in the flotation column (1); a ring-shaped foam chute (2) is formed in the edge of the top end of the flotation column (1), and the opening of the foam chute (2) faces upwards; a downward discharge opening (6) is formed in the bottom of the foam chute (2); an overflowing launder (3) is mounted in the center of the top end of the flotation column (1), supported on the foam chute (2) through a support frame (4), and communicated with the inside of the foam chute (2) through a flow guide tube (5). According to the utility model, the foam chute and the overflowing launder are combined, so that the problem that launder overturning is caused by stacking of foam can be prevented; meanwhile, the flotation column foam collection device has the characteristics of quickness in overflowing foam, no blockage, low manufacturing cost and the like.
Description
Technical field
The utility model relates to the mining machinery field, particularly relates to a kind of flotation column foam gathering-device.
Background technology
The utilization of Flotation in Recent Years post aspect ore dressing is more and more wider, due to its simple structure, takes up an area less, and has beneficiation enrichment than large, treating capacity advantages of higher, makes flotation column replace flotation device to find broad application.Flotation column refers to compressed air is seen through to the pneumatic flotation cell that porous media is inflated and stirred ore pulp.The agent structure of flotation column is cylindrical tube with bubble generator (also square or rectangular column) normally, in cylindrical shell with mine-feeding equipment, foam overflow or scrape device and compressed air input pipe network and bellows chamber etc.During flotation column work, the ore pulp be in harmonious proportion through medicament is fed by the mine-feeding equipment of cylinder middle and upper part, compressed air, through input pipe network and bellows chamber, then sees through porous media (as the cellular plastic short tube) and blasts from the cylinder bottom, and compressed air forms a large amount of tiny bubbles in cylinder.Ore particle slowly descends under Action of Gravity Field, and bubble is floating to rising through the ore pulp flowed downward, and ore particle and bubble, by counter current contacting and collision, are realized the selective mineralising of bubble.Bubble after mineralising rises floating to the ore deposit liquid level on flotation column top to be assembled and forms froth bed, overflow or with scraper plate, scrape after froth pulp; Mine tailing is by discharging by lifting device at the bottom of post.Current flotation column on the market has two kinds to the processing mode of foam: 1, utilize the froth paddle device, with scraper plate is reciprocating, foam is scraped in Foam Flowing Groove; 2, foam self-overflow type, the foam in flotation column relies on fully from excessive mode, from the top of flotation column along the surrounding overflow to Foam Flowing Groove.But the ubiquitous shortcoming of flotation column is worked stable not exactly at present, the flow of foam is also unstable, when the foam flow is large, because foam viscosity is large, flow velocity is slow, and the foam at barrel edge can be discharged in time, but the foam at middle part just can not be discharged in time, just cause foam to pile up, finally cause turning over groove.For turning over this problem of groove, although adopt screeding device to solve, the I&M of screeding device is all inconvenient, and the operation and maintenance cost is higher.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of cost lower and prevent that foam from turning over the flotation column foam gathering-device of groove.
The technical solution of the utility model is as follows: a kind of flotation column foam gathering-device, comprise flotation column (1), the through hole that there is upper and lower opening in described flotation column (1), the Foam Flowing Groove (2) of ring-type is installed at the top outward flange of this flotation column (1), the opening upwards of described Foam Flowing Groove (2), there is downward relief port (6) in the bottom of this Foam Flowing Groove (2), the outer overflow launder (3) of ring-type is installed at the center, top of described flotation column (1), should by bracing frame (4), be supported on described Foam Flowing Groove (2) by outer overflow launder (3), described outer overflow launder (3) is connected with Foam Flowing Groove (2) inside by mozzle (5).
While adopting above-mentioned flotation column foam gathering-device to carry out work, foam is not that single edge circumferentially flows into Foam Flowing Groove, but the edge part is along circumferential inflow Foam Flowing Groove, mid portion flows into annular foam collecting tank, so just foam is shunted, be unlikely to cause foam to be piled up, cause turning over groove, this simple structure, with low cost, ban the froth paddle device fully, greatly reduced production cost.
In order to accelerate flow velocity, facilitate the foam gravity flow, in described outer overflow launder (3), concentric locking collar is equipped with a plurality of interior overflow launders (7), in being somebody's turn to do, overflow launder (7) is identical with outer overflow launder (3) structure, adjacent two interior overflow launders (7) are fixedly linked by bracing frame (4), and adjacent two interior overflow launders (7) are connected by mozzle (5), outermost interior overflow launder (7) is fixedly linked by bracing frame (4) and outer overflow launder (3), and outermost interior overflow launder (7) is connected with outer overflow launder (3) by mozzle (5).
The endless groove that described Foam Flowing Groove (2) is comprised of inner panel (2a), outside plate (2b) and base plate (2c), this inner panel (2a) is intilted annular slab, and the peak of this inner panel (2a) is lower than the peak of outside plate (2b).Because inner panel slopes inwardly, foam can better outwards be piled up along the inclined plane of inner panel, when surpassing the peak of inner panel, just outwards is spilled in Foam Flowing Groove, and this structure can better prevent that foam from piling up and turn over groove.
Convenient for foam is outwards flowed out, can not stop up mozzle, described mozzle (5) is low inside and high outside being obliquely installed.
Beneficial effect: the utility model adopts Foam Flowing Groove and overflow launder to combine, and can prevent that foam from piling up so that turning over groove, also have simultaneously foam overflow fast, can not stop up, the characteristics such as low cost of manufacture.
