Abstract
Description
Technical Field
[0001] This utility model relates to the field of bauxite processing technology, specifically to a modified system of a flotation column beneficiation device for bauxite beneficiation. Background Technology
[0002] A flotation machine, short for flotation mineral processing machine, refers to mechanical equipment that completes the flotation process. In a flotation machine, after the slurry has been treated with reagents, it is agitated and aerated, causing some mineral particles to selectively adhere to the air bubbles. These particles float to the surface of the slurry and are scraped off to form froth products, while the rest remain in the slurry, thus achieving the purpose of separating minerals. There are many structural forms of flotation machines, the most common of which is the mechanically agitated flotation machine. In this type of flotation machine, the impeller is driven by a motor and a V-belt to rotate, generating centrifugal force to create negative pressure. This process draws in sufficient air to mix with the slurry while simultaneously agitating the slurry and mixing it with the reagents. At the same time, it refines the froth, causing the minerals to adhere to the froth and float to the surface of the slurry, forming mineralized froth. The height of the gate is adjusted to control the liquid level, allowing the useful froth to be scraped off by the scraper. In existing flotation machines, when flotating slurry, certain substances inside the slurry enter the foam when air is pressurized. However, since the foam floats on top of the slurry, its treatment is relatively troublesome. The usual treatment is to discharge the flotated slurry and then the foam, which results in the subsequent slurry being unusable, causing unnecessary waste and bringing certain adverse effects to the user experience. Utility Model Content
[0003] Purpose of the utility model: In view of the shortcomings of the prior art, this utility model provides an energy-saving and environmentally friendly flotation machine for mineral processing, which has the advantages of easy screening out foam and control of slurry discharge, and can effectively solve the problems in the background art.
[0004] Technical Solution: A modified flotation column beneficiation system for bauxite beneficiation, characterized in that: it includes a flotation tank, with multiple agitators at the upper end of the flotation tank, the agitators being connected to the flotation tank; an agitating rod inside the flotation tank, connected to the agitators, and an agitating head on the agitating rod; a feed pump on one side of the flotation tank, with a feed pipe connected to the feed pump on one side; a blower at the upper end of the feed pump, connected to the flotation tank; a baffle at the other end of the flotation tank, with an outlet at one end of the baffle; and a cleaning port at the lower end of the flotation tank.
[0005] Specifically, the stirring head is provided with a stirring blade, which is arranged in an inclined structure and is arranged in a ring on the stirring head.
[0006] Specifically, the stirring plate is provided with a U-shaped groove.
[0007] Specifically, the feed inlet is the feed inlet of the solenoid valve.
[0008] Specifically, the baffle is arranged in an inclined structure.
[0009] Specifically, the fan is an induction fan, and the position of the fan is higher than the position of the baffle.
[0010] Beneficial effects:
[0011] The advantages of this invention are as follows: By using a blower, the increased airflow during slurry flotation can effectively float the flotation foam. Under the action of the blower motor and fan blades, the foam floating on the surface can be discharged from the foam outlet, improving the slurry utilization rate. The inclined baffle can effectively control the slurry discharge rate, better promote the flotation of the slurry by the flotation machine body, further increase the flotation efficiency, and also increase the outlet flow, providing a certain efficiency for controlling the demand.
