Description

Dense pond anti-foam overflow arrangement

The technical field is as follows:

the utility model relates to a molybdenum ore production facility field, concretely relates to dense pond anti-foam overflow arrangement.

Background art:

in the production of molybdenum ore, the molybdenum ore pulp floated by the flotation machine is required to be settled and concentrated by a thickener, the thickened ore pulp is discharged from a bottom flow port of the thickener, and clear liquid overflows from a top overflow weir into an annular chute and is discharged. However, in the actual concentration process, under the action of the flotation reagent, a large amount of molybdenum ore foam still floats above the liquid level of the ore pulp in the thickener, and along with the continuous injection of the ore pulp, the foam carrying the molybdenum ore overflows into the annular chute along with the clarifying solution, so that the molybdenum loss is caused.

The utility model has the following contents:

an object of the utility model is to provide a dense pond anti-foam overflow arrangement who reduces molybdenum loss.

The utility model discloses by following technical scheme implement:

a dense pool anti-foam overflow device comprises a dense pool body, wherein an annular chute is arranged at the top of the dense pool body, and an overflow weir is arranged at the edge of the inner side of the annular chute; the device also comprises an annular foam baffle and an annular foam flushing pipe; a plurality of uniformly distributed supports are fixed at the top of the overflow weir, the outer side of the annular foam baffle is fixed on the supports, and the bottom end of the annular foam baffle is positioned below the top end of the overflow weir; a pipe hoop for fixing the annular foam flushing pipe is fixed on each bracket, and a plurality of flushing through holes are formed in the bottom of the annular foam flushing pipe; the annular foam flushing pipe is positioned right above the annular foam baffle.

Preferably, the top end of the annular foam baffle is an inclined plane inclined towards the circle center.

Preferably, the annular foam baffle is formed by splicing a plurality of arc-shaped plates, and each arc-shaped plate is fixed on a support at a corresponding position; the adjacent arc-shaped plates are abutted through clamping grooves.

The utility model has the advantages that: the foam floating on the surface of the ore pulp flows to the edge along with the clarifying liquid and is blocked at the inner side by the annular foam baffle, the clarifying liquid can reach the overflow weir from the lower part to overflow, the flushing water is discharged downwards from the flushing through hole, the foam blocked by the annular foam baffle is broken, molybdenum ore particles carried by the foam are settled in the ore pulp, the loss of molybdenum is reduced, and the recovery rate is improved.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a schematic view of the installation of the present invention on the thickening tank body;

FIG. 3 is an enlarged view of a portion of FIG. 2;

fig. 4 is a schematic view of the splicing of the arc plates of the present invention.

In the figure: the device comprises a thickening tank body 1, an annular chute 2, an overflow weir 3, an annular foam baffle 4, an annular foam flushing pipe 5, a support 6, a pipe hoop 7, a flushing through hole 8, an arc-shaped plate 9 and a clamping groove 10.

The specific implementation mode is as follows:

as shown in fig. 1 to 4, the anti-foaming overflow device for the thickening tank comprises a thickening tank body 1, wherein an annular chute 2 is arranged at the top of the thickening tank body 1, and an overflow weir 3 is arranged at the inner side edge of the annular chute 2; the device also comprises an annular foam baffle 4 and an annular foam flushing pipe 5; a plurality of uniformly distributed supports 6 are fixed at the top of the overflow weir 3, the outer side of the annular foam baffle 4 is fixed on the supports 6, and the bottom end of the annular foam baffle 4 is positioned below the top end of the overflow weir 3; a pipe hoop 7 for fixing the annular foam flushing pipe 5 is fixed on each bracket 6, and a plurality of flushing through holes 8 are formed in the bottom of the annular foam flushing pipe 5; the annular foam flushing pipe 5 is positioned right above the annular foam baffle 4;

the ore pulp after flotation is discharged into the thickening tank body 1, the foam floating on the surface flows to the edge along with the clarified liquid, and the clarified liquid can reach the overflow weir 3 from the lower part and overflow because the bottom end of the annular foam baffle 4 is positioned below the top end of the overflow weir 3, and the foam is blocked inside by the annular foam baffle 4; the annular foam flushing pipe 5 is connected with a water source and is used for supplying the water source at regular time, flushing water is discharged downwards from the flushing through hole 8, and foam blocked by the annular foam baffle 4 is broken, so that molybdenum ore particles carried by the foam are settled in ore pulp, the loss of molybdenum is reduced, and the recovery rate is improved.

The top of annular foam baffle 4 is the inclined plane to the centre of a circle slope, and annular foam flushing pipe 5 exhaust sparge water all can fall 4 inboards of annular foam baffle under the direction on inclined plane after falling 4 tops of annular foam baffle, washes the foam, improves the utilization ratio of sparge water, improves defoaming efficiency.

The annular foam baffle 4 is formed by splicing a plurality of arc-shaped plates 9, the arc-shaped plates 9 can be made of plastic materials, and each arc-shaped plate 9 is fixed on the bracket 6 at the corresponding position; the adjacent arc plates 9 are abutted through the clamping grooves 10, and the annular foam baffle plates 4 spliced by the arc plates 9 are arranged, so that the maintenance is convenient.
