Description
Technical field
The utility model belongs to the preparation equipment technical field, is specifically related to a kind of simple process, and working stability has the flotation unit that defoaming function prevents that effectively the concentrate blister runs off reliably.
Background technology
Flotation beneficiation is to use one of most important technique, uses very extensive especially.According to statistics, there is the Non-ferrous minerals more than 90% all to use floatation process to process.In addition, also be used for the ore dressing of ferrous metal, noble metal and nonmetallic mineral, even in recent years to the field of purification of water quality etc.Under existing floatation process condition, in the early stage of floatation process, need to produce stable foam, so that purpose mineral and gangue mineral are separated.But in floatation process later stage concentrate processing procedure, wish that foam breaks as early as possible, to improve ore dressing plant concentrate conveying capacity, reduce the concentrate loss, improve the utilization ratio of concentration basin, reduce environmental pollution.Under prior art, in concentration process, due to floating agent, water quality, mineral granularity, temperature, the many factors actings in conjunction such as pressure cause foam stability stronger, and viscosity is large, are difficult to vanish, the part concentrate has been lost from the concentration basin overflow, reduce thickening efficiency, increased cost, wasted resource.For this reason, develop a kind of can be at flotation concentrate later stage high effective defoaming, reduce the loss of concentrate, improve the flotation technology with the bubble function of going out of the utilization ratio of concentration basin, be of great immediate significance, and can produce great economic benefit and social benefit.
The utility model content
The purpose of this utility model is to provide a kind of simple process, and working stability has the flotation unit that defoaming function prevents that effectively the concentrate blister runs off reliably.
The purpose of this utility model is to realize like this, comprise run-off, transmission device, agitating device, cage sand bucket, mineral-feeding pipe and downflow weir, on the main falsework of described run-off, transmission device is set, the be in transmission connection agitating device of run-off bottom of transmission device, the coaxial below that is arranged at transmission device of described cage sand bucket, the run-off top arranges overflow launder, and mineral-feeding pipe is set above described cage sand bucket; Described downflow weir inboard arranges overflow baffle.
The utility model is by arranging overflow baffle and high-pressure defoaming apparatus, the utility model is simple in structure, easy for installation, greatly reduced the floating generation that contains the copper concentrate foam in concentration basin upper strata, also further reduce the copper concentrate foam to the impact of subsequent job, improved utilization rate and the flotation efficiency of concentration basin, the copper concentrate that can reduce by 150 tons of left and right in a year runs off, greatly reduce production cost, created larger economic benefit.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but must not be limited the utility model by any way, any change or improvement based on the utility model training centre is done all belong to protection domain of the present utility model.
As shown in Figure 1 and Figure 2, the utility model comprises run-off 1, transmission device 2, agitating device 3, cage sand bucket 4, mineral-feeding pipe 5 and downflow weir 11, on the main falsework of described run-off 1, transmission device 2 is set, the be in transmission connection agitating device 3 of run-off 1 bottom of transmission device 2, the coaxial below that is arranged at transmission device of described cage sand bucket 4, run-off 1 top arranges overflow launder 7, and described cage sand bucket 4 tops arrange mineral-feeding pipe 5; Described downflow weir 11 inboards arrange overflow baffle 8.
Described overflow baffle 8 is installed on the run-off inwall by support.
Spillwag chute 600 ~ 800mm is goed deep in described overflow baffle 8 bottoms, and the top exceeds spillwag chute 200 ~ 400mm.
The mounting bracket spacing of described overflow baffle 8 is 1300 ~ 1700mm.
Distance between described overflow baffle 8 and downflow weir 11 is 100 ~ 200mm, is optimized for 150mm.
Described overflow baffle 8 surfaces arrange corrosion-inhibiting coating.
The annular soaked pipe 9 that goes out is set on described overflow launder 7, and go out soaked pipe 9 bottoms of described annular are uniform to the centroclinal hole for water spraying of run-off 1, and the aperture of described hole for water spraying is 2 ~ 6mm.
Described annular is gone out the diameter of soaked pipe 9 than the little 10 ~ 40mm of diameter of run-off 1.
The other horizontal of described cage sand bucket 4 are through the straight line of the run-off 1 soaked pipe 10 that goes out.
