Description

Defoaming and spraying device of flotation machine

Technical Field

The utility model belongs to the technical field of the ore dressing, concretely relates to flotation device defoaming spray set.

Background

When the flotation machine floats and selects the required ore pulp foam, the mineralized foam is scraped to the foam tank through the flotation scraper blade, minerals carried on the foam can automatically flow to a pipeline through opening at the bottom of the foam tank due to self gravity, but the foam is difficult to be automatically eliminated without external force because the dissociation of the alcohol foaming agent in water is small. For the defoaming device of the existing flotation machine, under the condition of generating a large amount of foams, the defoaming effect is not ideal, the concentration of flotation in the next operation is easy to reduce, and meanwhile, a layer of film with larger surface tension is easily formed on the mixture of the foams with trace ore and ore pulp at the pipeline discharge port at the bottom of the tank, so that the flow of mineralized foams is blocked, and finally the overflow tank is caused. If not in time management and control, can cause the metal to run off on the one hand, economic benefits receives the influence, and on the other hand can pollute work platform, increases the sanitary maintenance degree of difficulty of work platform.

Disclosure of Invention

In order to solve the technical problem, the utility model provides a flotation device defoaming spray set can effectively eliminate the foam.

The specific technical scheme is as follows: a defoaming and spraying device of a flotation machine comprises a flotation machine body, wherein a foam discharge port is formed in the upper portion of the side wall of one end of the flotation machine body, a scraper blade device is rotatably arranged above the foam discharge port, a foam groove is formed in the outer side of the foam discharge port of the flotation machine body, the bottom of the foam groove is U-shaped and is obliquely arranged (the bottom of the foam groove is inclined due to the fact that one end of the foam groove is tilted), a bottom opening is formed in the lower end port of the foam groove, a rotating wheel is; the side wall above the foam tank is provided with a plurality of spray water nozzles through water pipes, and the water nozzles are provided with regulating valves.

The spray water nozzle is arranged above the flotation foam tank, the lower half part of the spray water nozzle is a spherical water nozzle with spray holes, the detachable structure is connected to the water pipe, and the water pipe can be provided with one water nozzle at intervals according to the specific spray range of the water nozzle, so that the defoaming area is effectively increased. The runner is also arranged at the through hole at the bottom of the tank, so that the surface tension of water is destroyed by the rotating mechanical force to break the water film formed at the through hole at the bottom of the tank, and the flow of mineralized foam and ore pulp is facilitated.

The utility model discloses to the higher or big and groove problem that emits that appears of flotation medicament quantity of the higher or flotation agent degree of ore nature mud matter degree in current ore dressing plant flotation workshop, a high-efficient flotation machine sprays fire fighting equipment is proposed at present. This spray set establishes in flotation foam groove top, and the shower water nozzle is the spherical water nozzle that the lower half was covered with the orifice, and detachable construction connects on the water pipe, and the spaced arrangement effectively increases the defoaming area. The runner is also arranged at the through hole at the bottom of the tank, so that the surface tension of water is destroyed by the rotating mechanical force to break the water film formed at the through hole at the bottom of the tank, and the flow of mineralized foam and ore pulp is facilitated.

Detailed Description

The defoaming spraying device of the flotation machine shown in fig. 1-3 comprises a flotation machine body 1, wherein a foam discharge port 2 is arranged at the upper part of the side wall of one end of the flotation machine body 1, a scraper blade 3 is rotatably arranged above the foam discharge port 2, a foam tank 4 is arranged outside the foam discharge port 2 of the flotation machine body, the bottom of the foam tank 4 is U-shaped and is obliquely arranged (one end of the foam tank tilts to cause the bottom to incline), a bottom opening 5 is arranged at the lower end port of the foam tank 4, a rotating wheel 6 is arranged on the bottom opening 5, and a plurality of blades are arranged on;

the side wall above the foam tank is provided with a plurality of spray water nozzles 7 through water pipes, and the spray water nozzles are provided with regulating valves.

The mineralized foam is scraped to flotation froth groove 4 by flotation scraper blade ware, and the flotation froth groove is tilting U type cell body, and the discharge port of foam cell body inclination below is connected and is collected to the specified area by the pipeline, and defoaming spray set includes water pipe 8 and shower water nozzle 7, and defoaming spray set installs on the upper portion of foam groove 4, and runner 6 is installed to 5 departments of bottom opening, and the ore pulp drives the runner blade rotation to mechanical force destroys the membrane that is formed at the mouth of pipe by the great foam of surface tension.
