A lifting type flotation machine for graphite production

Abstract

The invention discloses a lift type flotation machine for graphite production. The lift type flotation machine comprises a cylinder body, an upper end cover and a conical bottom cover, wherein an air and liquid passing pipe is arranged on the side surface of the upper end cover; a feeding hopper is arranged on the side surface of the cylinder body; an air sucking and circulating device is arranged inside the upper end cover; a mixing chamber is formed inside the cylinder body; two vertically-distributed fixing rings are arranged on the inner wall of the mixing chamber; a negative pressure regulating device and an air flow mixing device are arranged inside the mixing chamber; a second motor is arranged above the upper end cover and is fixedly connected to a lifting plate by a locating mechanism; the lifting plate is connected with the upper end cover by a lifting mechanism. The lift type flotation machine is simple in structure, high in practicability and capable of lifting up and lifting down the air flow mixing device, increasing the contact area of air and liquid and improving the flotation effect; moreover, the air pressure in the mixing chamber can be regulated by the negative pressure regulating device; therefore, the service life of the flotation machine is effectively prolonged, the structure of the flotation machine is simplified, and the work efficiency of the flotation machine is improved.

Description

technical field [0001] The invention relates to the technical field of graphite processing, in particular to a lifting type flotation machine for graphite production. Background technique [0002] The flotation machine is suitable for the separation of non-ferrous metals, and it can also be used for the separation of non-metals. The impeller is mainly driven by the motor to rotate, and the centrifugal force is generated to form a negative pressure. At the same time, the foam is refined, so that the minerals adhere to the foam, float to the surface of the slurry to form mineralized foam, adjust the height of the ram, control the liquid level, and make useful foam be scraped out by the scraper. [0003] The flotation machines used to produce graphite in the prior art usually have a drive motor fixedly connected to the top surface of the tank, which cannot be lifted up and down. Therefore, it can only be used for flotation of materials with a constant liquid level, and the prac...

AI Technical Summary

Problems solved by technology

[0003] The flotation machines used to produce graphite in the prior art are usually fixedly connected to the drive motor on the top surface of the tank, which cannot be lifted up and down, so it can only be used for flotation of materials with a constant liquid level, and the practicability is greatly reduced. Moreover, the negative pressure can only be generated by the centrifugal action of the rotating mechanism, so the adjustment of the negative pressure is limited, so the flotation effect is poor
