Abstract
The invention relates to a de-foaming agitation tank for foam flotation. The tank comprises a tank body, wherein both sides of the tank body are provided with an ore feed pipe and an ore discharge pipe respectively; a circulating barrel and a transmission device are arranged in the tank body; and the upper part of the circulating barrel is connected with a bracket of the transmission device, while the lower part is connected with the tank body. The tank has the advantages that: de-foaming can be performed effectively under the driving action of the transmission device through the agitation tank provided with the circulating barrel, so that a gas-liquid-solid three-phase mixture becomes a liquid-solid two-phase mixture after gas is removed; moreover, the tank has a simple structure, is convenient to maintain and has low using cost.
Description
Technical field
The present invention relates to a kind of froth breaking tank diameter, relate in particular to a kind of froth breaking tank diameter that is used for flotation froth, belong to ore dressing auxiliary equipment technical field.
Background technology
In the flotation of ore pulp operation, ore pulp with charge into or inhaled air mixes because the effect of foaming agent, collecting agent produces a large amount of flotation froths and rises on the flotation device liquid level, foam is discharged from flotation device and is used for the next procedure operation.And a large amount of bubbles of discharging are difficult to break voluntarily air is separated with ore pulp, even much bubble incorporation becomes bigger bubble together, have a strong impact on next procedure as concentrated, ore pulp pumping, ore pulp gravity flow operation.Mainly taked high-velocity flow to break up the method for bubble, but unsatisfactory than the defoaming effect of minute bubbles, the part mine adopts foam pump to carry out the pumping foam, causes the problem that foam pump energy consumption and spare parts consumption are excessive, the working service cost is too high in the past.
Therefore a kind of froth breaking well of invention design, and consumption is few, and equipment easy to maintenance becomes a kind of inexorable trend.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of froth breaking tank diameter that is used for flotation froth is provided, get rid of a large amount of bubbles to reach, easy to maintenance, the purpose that cost is low.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of froth breaking tank diameter that is used for flotation froth, comprise cell body, described cell body both sides are respectively equipped with mineral-feeding pipe and ore discharge pipe, be provided with circulating barrel and transmission device in the described cell body, the top of described circulating barrel is connected with the support of transmission device, and the bottom of described circulating barrel links to each other with cell body.
The invention has the beneficial effects as follows: by being provided with the tank diameter of circulating barrel, froth breaking effectively under the drive of transmission device becomes liquid, solid two-phase mixture after making the gas, liquid, solid three-phase mixture remove gas, and simple in structure, easy to maintenance, use cost is cheap.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described circulating barrel comprises straight tube, the cone that connects successively and goes up straight tube that described straight tube is provided with the hole that is connected as a single entity with mineral-feeding pipe, is provided with impeller in the described straight tube, described impeller is rotated by actuator drives, and described straight tube is connected with the support of transmission device by at least 2 suspension brackets.
Further, described impeller is installed on bottom in the straight tube.
Further, the diameter of described impeller is less than the internal diameter of straight tube.
Further, described mineral-feeding pipe is positioned at the top of impeller direction of rotation tangent line.
Further, fixedly connected with cell body by supporting angle steel in the bottom of described circulating barrel.
Description of drawings
Fig. 1 is the overall structure schematic diagram that is used for the froth breaking tank diameter of flotation froth of the present invention;
Fig. 2 is the structural representation that enters the position, ore deposit that is used for the froth breaking tank diameter of flotation froth of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present invention and feature are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.
Shown in Fig. 1-2, the described froth breaking tank diameter that is used for flotation froth of the embodiment of the invention, comprise cell body 1, described cell body 1 both sides are respectively equipped with mineral-feeding pipe 2 and ore discharge pipe 3, be provided with circulating barrel 4 and transmission device 5 in the described cell body 1, the top of described circulating barrel 4 is connected with the support 501 of transmission device 5, fixedlys connected with cell body 1 by supporting angle steel 6 in the bottom of described circulating barrel 4; Described circulating barrel 4 comprises straight tube 401, the cone 402 that connects successively and goes up straight tube 403, described straight tube 403 is connected with the support 501 of transmission device by at least 2 suspension brackets 7, the bottom is provided with impeller 8 in the described straight tube 401, described impeller 8 is driven by transmission device 5 and rotates, described impeller 8 diameters are less than the internal diameter of straight tube 401, described straight tube 401 is provided with the connecting hole 4011 that is connected as a single entity with mineral-feeding pipe 2, and described mineral-feeding pipe 2 is positioned at the top of impeller 8 direction of rotation tangent lines.
During use, the foam ore pulp enters down the position of straight tube 401 parts a little more than impeller 8 setting height(from bottom)s through mineral-feeding pipe 2 continuously along the direction of rotation tangent line of impeller 8; Impeller 8 high speed rotations form negative pressure, cause bubble to break rapidly under the linear differential synergy of brute force stirring impact, inflow foam and the impeller 8 of negative pressure, impeller 8; Because atmospheric density is lower than pulp density, air floats in circulating barrel, the cone 402 of circulating barrel 4 is used to strengthen the surface area that air overflows, being beneficial to air removes thoroughly, the top edge of going up straight tube 403 of circulating barrel 4 exceeds the liquid level surface of cell body 1, thereby the air that overflows can not mix with ore pulp once more, and the comprehensive density of the ore pulp after the degassing increases, flow out circulating barrel downwards and enter in the cell body 1, flow out cell body 1 continuously through ore discharge pipe 3.
Operation was eliminated flotation bubble after the present invention was applicable to the flotation of industries such as metal and non-metal mine, building materials, chemical industry, coal.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
