Description

Technical Field

[0001] This utility model relates to the field of flotation equipment technology, specifically to the flipping structure of a forward and reverse flotation device. Background Technology

[0002] The combined process of phosphate ore scrubbing and forward / reverse flotation is a composite beneficiation technology for medium- and low-grade weathered phosphate ore. Its core is to achieve efficient enrichment and recovery of phosphate resources through the synergistic effect of physical scrubbing pretreatment and chemical flotation separation. It is particularly suitable for difficult-to-process ores with high mud content and fine particle size. The flotation machine is a commonly used piece of equipment in the phosphate ore processing; the flotation machine mainly consists of a power transmission system, a slurry processing unit, an aeration system, and a frothing mechanism.

[0003] The froth scraping mechanism mainly consists of continuously rotating scrapers, which are used to scrape out the foam generated during the flotation process in order to separate the minerals. However, in actual use, the scrapers and rotating shafts of the froth scraping mechanism are constantly immersed in the minerals, and the acidic substances contained in the minerals will corrode the connecting structures such as bolts. When the scrapers and rotating shafts are worn and need to be replaced, the corroded bolts are difficult to disassemble, which increases the difficulty of disassembling and replacing related components. In view of this, we propose a rotating structure for the forward and reverse flotation device. Utility Model Content

This design facilitates the operation of the rotating shaft.

[0031] In this embodiment, a guide plate 29 is fixed to one side wall of the movable plate 24, and a guide groove 202 is provided on the mounting plate 20 to be slidably connected to the guide plate 29.
