Description

TECHNICAL FIELD

[0001] The utility model relates to mineral flotation technical field, concretely relates to a kind of ore pulp bubble transverse flow guide device and flotation machine. BACKGROUND

[0002] Different minerals need to be screened after ore exploitation, and a flotation machine needs to be used. The main principle of the flotation machine is to use the difference in the surface properties of minerals to bring out the minerals with poor hydrophilicity by the buoyancy of bubbles. Then, the scum floating on the surface of the ore pulp is scraped to the scum tank by a scum scraping mechanism so that the scum enters the next process.

[0003] In the prior art, the scum scraping mechanism is mainly driven by a motor to rotate a shaft. A plurality of scrapers are fixedly installed on the shaft. The rotation of the shaft drives the scrapers to rotate, thereby scraping the scum into the scum tank. It is found in the actual use of the scrapers that the scrapers also push the top layer of ore pulp to move in the direction of the scum tank during the process of driving the scum to move forward. Since the scraping of the scum by the scrapers is intermittent, the ore pulp pushed forward will flow back, i.e., flow in the direction away from the scum tank when the first scraper is separated from the ore pulp. Most of the scum on the top surface of the ore pulp is scraped off, and the backflow of the ore pulp also reduces the amount of scum floating in front, thereby causing the second scraper to push less scum when it reaches the ore pulp.

[0004] In summary, the existing scum scraping mechanism has low efficiency due to the intermittent scraping of the scum, which causes the backflow of the ore pulp and affects the efficiency of the flotation. UTILITY MODEL CONTENTS
