Description

Technical Field

[0002] Flotation machine is the abbreviation of flotation concentrator, which refers to the mechanical equipment that completes the flotation process. In the flotation machine, the pulp treated with reagents is stirred and aerated, so that some mineral particles are selectively fixed on the bubbles; the particles that float to the surface of the pulp are scraped out to form foam products, and the rest are retained in the pulp to achieve the purpose of separating minerals. There are many structural forms of flotation machines, and the most commonly used is the mechanical stirring flotation machine.

[0003] In the prior art, a Chinese patent with the announcement number CN204564354U discloses a flotation machine dedicated to gold ore fineness matching, which adopts the scheme of "including a frame and a flotation box arranged on the frame, a stirring blade arranged in the flotation box, and a motor connected to the stirring blade drive, the flotation box has a fine selection bin and a rough selection bin, both flotation bins are provided with stirring blades, and both mouths are provided with a scraping bubble device, a slurry screening cylinder is provided above the fine selection bin, the mouth of the slurry screening cylinder extends to the top of the rough selection bin, and the mouths of the fine selection bin and the rough selection bin are connected with a liquid supply pipeline". This scheme is provided with a slurry screening cylinder and a fine and coarse flotation bin, which can perform coarse and fine screening, and flotation operations respectively. The screened operation can reasonably configure the slurry through the reagent water supply system and the reagent supply device. Its overall structure is reasonable, easy to use, and the ore dressing effect is better than that of a traditional flotation machine, and the efficiency is higher.

[0004] However, the above scheme still has some shortcomings. For example, the reagent feeding pipeline of the above scheme is arranged above the box body, resulting in that when the reagent is actually dosed, the reagent will float on the surface as the slurry is stirred, and cannot be fully and evenly mixed with the slurry, resulting in unsatisfactory reaction effect. In view of this, the utility model proposes an automatic reagent adding device for a gold flotation machine. Utility Model Content
