Problems solved by technology
It is more difficult to make a flotation column with a larger diameter, such as a cylinder with a diameter of more than 5 meters
In addition, it is difficult to transport such a large flotation column from the factory to the site
[0006] Furthermore, the flotation column with the swirling jet aerator in the prior art needs to set a baffle in the cavity opposite to the injection port of the aerator, and a baffle is arranged in the cavity near the injection port, and its structure is relatively Complex, and each baffle is a separate structure, the strength and rigidity must meet the requirements, the structure will be more complicated, and the production will be more difficult

The invention provides a swirl jetting flotation column of a polygonal tube body. The swirl jetting flotation column comprises a flotation column tube body, wherein the tube body is a polygonal columnar tube body, the tube body is formed by welding a plurality of flat plates, an ore pulp inlet is arranged on the lower side wall of the tube body, the upper part of the tube body is provided with a concentrated ore outlet, an ore pulp inlet pipe is connected onto the ore pulp inlet, a swirl jetting inflator is arranged on the ore pulp inlet pipe, the lower bottom of the flotation column is provided with an opening, and the opening is connected with a tailings slag discharge pipe. The flotation column of the polygonal tube body provided by the invention can be used for manufacturing high-volume flotation columns, in addition, the manufacture is easy, and the transportation is convenient. A baffle plate body is arranged in the middle inside the tube body, so the baffle plate structure is more reasonable, more stable and simpler. The flotation column bottom of the tailings outlet is provided with a plurality of openings, and a conical tailings discharge outlet is averagely divided, so for large-scale flotation columns with the diameter being greater than 5m or reaching 15m, the deposition phenomena cannot occur. The tube body volume is increased, so the treatment quantity and the recovery rate are obviously improved.
Description
technical field [0001] The invention belongs to the technical field of mineral flotation, and relates to a mineral flotation device, in particular to a swirling jet flotation column. Background technique [0002] In the prior art, the key device of the flotation equipment used in mineral flotation is the flotation column. Existing general flotation columns all include a columnar barrel-shaped flotation column cavity, the lower end of which is connected to a tapered barrel, and the cylindrical barrel and the tapered barrel are connected. see figure 1 , the lower part of the flotation column cavity 1 is provided with a pulp inlet 011, and the upper part is provided with a concentrate outlet 013, and a tailings outlet is provided on the side wall of the conical cylinder, and a U-shaped tailings outlet is connected to the tailings outlet to discharge Tube. The pulp containing the flotation agent entrains a large amount of air from the pulp inlet into the flotation column, whe...
