Description

Device for directly feeding chemicals from hollow shaft of large flotation machine

Technical Field

The utility model relates to a device for directly adding medicine from a hollow shaft of a large flotation machine, which is suitable for adding and applying the medicine of a flotation system arranged in a ladder self-flowing manner.

Background

In the field of mineral processing, high-grade ores are gradually reduced along with the continuous development of mineral resources, the ore selectivity difficulty is increased, and for low-grade and refractory ores, a larger processing scale is needed to obtain good economic benefits; meanwhile, the equipment and manufacturing level of mine equipment are continuously improved, the equipment scale tends to be large-scale, and the volume of the maximum flotation machine used at present reaches 320m³Even the experiment of 640m in the mountain ore dressing plant of Jiangtong copper group by Beijing institute of mining and metallurgy³The oversized flotation machine. It is understood that the volume of the flotation machine is 70m or more³And then, because the power of the motor is higher, the load is higher during starting, most of the self-flowing flotation machines are adopted, and all the flotation machines are arranged in stages. The flotation machine that the ladder was arranged is at the application in-process, and the flotation medicament drips into from middle case upper portion, because the medicament proportion is little and float on the ore pulp surface (the middle case can accumulate a large amount of foams in the connection of most ore dressing plant flotation machine, and the medicament directly drips on the foam), is difficult to take place chemical reaction with the ore pulp intensive mixing, leads to the mineral mineralization effect relatively poor, influences the ore dressing effect, has increased the medicament quantity simultaneously. Some ore dressing plants try to insert the chemical pipeline directly below the liquid level of the ore pulp, so that the problem of floating of the chemical can be solved to a certain extent, but the pipeline is easy to enter the ore pulp to block, and the phenomenon of flow cutoff of the chemical is often found.

Therefore, the development of a device for directly feeding the chemicals from the hollow shaft of the large flotation machine has practical significance.

Disclosure of Invention

The utility model aims at overcoming the not enough of prior art, provide a direct device that adds medicine from large-scale flotation device quill shaft, it lets the medicament not float on flotation device middle box ore pulp foam surface, makes medicament and ore pulp in the ore pulp direct contact, improves the effect of flotation medicament and ore pulp.

In order to complete the task, the novel use adopts the following technical scheme:
