Problems solved by technology

Changed to a throat injection, the high-speed flowing slurry, compressed air, and chemicals are sprayed out through the throat, and the pressure is high, and the problem of wear on the injection port of the throat still exists; the high-speed flowing slurry, compressed air, and chemicals are injected through the throat On the solid flange, change the direction and diverge to the surrounding open circuit mineralization, due to the concentration of ore slurry spraying, the dispersion effect in the flotation tank is poor

Abstract

The invention relates to the technical field of mineral flotation equipment, and specifically discloses a release head of a flotation mineralizer. The release head of the flotation mineralizer includes a release head support, a throat is arranged on the release head support, and the lower end nozzle of the throat is a tapered nozzle with a small top and a large bottom. The lower side of the cone is provided with a tapered splitter cone coaxially arranged with the tapered nozzle, the top of the tapered splitter cone extends into the tapered nozzle, and the outer circumference of the tapered splitter cone There is a distribution channel between the inner wall of the tapered nozzle. In the release head of the flotation mineralizer provided by the present invention, the ore slurry injected through the conical nozzle is evenly dispersed, and the wear on the conical nozzle is small, and the mineralized foam formed in the flotation tank can float up stably, which is conducive to the formation of stable foam layer, there will be no turning over phenomenon.

Description

technical field [0001] The invention relates to the technical field of mineral flotation equipment, in particular to a release head of a flotation mineralizer. Background technique [0002] The flotation mineralizer is the core component of the flotation cell or flotation column equipment. The mineralizer includes two parts: a bubble generator and a release head. The release head is one of the important parts of the mineralizer. The Chinese patent with the notification number CN101439315B discloses a transmissionless flotation cell, wherein the slurry injection device 8 is a release head, which is an existing common release head structure. The slurry injection device 8 is welded or cast with more than one Nozzles 9, the number of nozzles 9 is generally 3-12, and the diameter of each nozzle is 3-25mm. The existing discharge head is easy to cause blockage due to the small diameter of the nozzle; and the flotation mineralizer is aimed at the flotation of fine-grained minerals....
