TECHNICAL FIELD
[0001] The utility model relates to a kind of dense pool devices of purifying floatation froth, belong to mineral processing concentration equipment field. BACKGROUND
[0002] Floatation tailings usually contain a certain amount of floatation reagent, due to the hydrophobicity of floatation reagent, the foam that is difficult to handle appears on the liquid surface when tailings are fed into the thickener for concentration, the common thickener adopts the overflow way to concentrate slurry and purify water quality, but the foam will be attached to minerals and flow out with overflow baffle, thereby affecting the water quality of thickener overflow water, affecting the water quality of concentrator backwater, further affecting the floatation effect. In addition, the foam of floatation tailings overflow water is mainly caused by hydrophobic floatation reagent, and the foam enters metal equipment and facilities such as pipeline and water pump with water, which continuously increases the amount of foam during flow, causing more serious cavitation phenomenon and affecting the service life of equipment and facilities.

[0004] The technical scheme adopted by the utility model to solve its technical problem is: a kind of dense pool device of purifying floatation froth, including the pool body of circular structure, overflow baffle is provided on the upper end of pool body, further including foam baffle, the foam baffle is arranged in the inner side of the inner wall of the upper end of pool body, and is spaced apart from pool body, the height of foam baffle is greater than the height of overflow baffle.
[0005] Among them, the upper end face of the pool body in the above device is provided with a track.
[0006] Further, the upper end face of the foam baffle in the above device is coplanar with the installation base surface of the track.
[0007] Among them, the lower end outer wall of the foam baffle in the above device is wedge-shaped structure.
[0008] Further, the upper end inner wall of the pool body in the above device is inclined step structure, and the distance between the lower end outer wall and the upper outer wall of foam baffle and the inner wall of pool body is equal.
[0009] Among them, the overflow channel formed by the foam baffle and the inner wall of the pool body in the above device is multiple and spaced apart.
[0010] Among them, the foam baffle in the above device is circular ring, and is adapted with the upper end inner wall of pool body.
[0011] The device has the advantages that the foam is separated by the foam baffle, the overflow water flows into the overflow channel formed by the foam baffle and the inner wall of the pool body from the lower end of the foam baffle, and the device can prevent the foam from entering the overflow water because the height of the foam baffle is greater than the height of the overflow baffle.

[0016] The device will be further described below with reference to the drawings.
[0017] As shown in the drawings, Figs. 1 to 3 The device is an improved device for the existing thickener, and prevents the foam floating on the liquid surface from entering the overflow water. Specifically, the foam baffle 2 is arranged on the inner side of the upper end of the pool body 1, and the foam baffle 2 is arranged in a spaced manner with the pool body 1. Meanwhile, the height of the foam baffle 2 is greater than the height of the overflow baffle 11, so that the overflow water in the pool body 1 cannot overflow from the upper part of the foam baffle 2, but can only flow into the overflow channel 4 formed by the foam baffle 2 and the inner wall of the pool body 1 from the lower end of the foam baffle 2, and then overflow from the overflow baffle 11. This structure can make the foam layer 3 float on the surface layer of the liquid, so as to realize purification of the overflow water.
[0018] Preferably, the upper end surface of the pool body 1 in the device is provided with a track 12. Those skilled in the art can understand that, in order to facilitate the circular motion of the thickener, the upper end surface of the pool body 1 in the device is preferably provided with a track 12 for supporting and ensuring stable operation of the device.
[0019] Preferably, the upper end surface of the foam baffle 2 in the above device is coplanar with the installation base surface of the track 12. Those skilled in the art can understand that the height of the foam baffle 2 in the device is preferably considered in view of the bearing load of the pool body 1, and the upper end surface of the foam baffle 2 is preferably coplanar with the installation base surface of the track 12.
