Description

Technical Field

[0001] The utility model relates to the technical field of flotation machines, in particular to a flotation machine scraper cleaning device. Background Art

[0002] A flotation machine is a mechanical device used to complete the flotation process. It uses stirring and aeration to make mineral particles selectively attach to bubbles and float to the surface of the slurry to form foam products, thereby achieving mineral separation. Flotation machines have various structural forms, among which the mechanical stirring flotation machine is the most commonly used one. When the flotation machine is in use, its scraper needs to be cleaned to improve the flotation effect.

[0003] For example, a flotation machine scraper cleaning device disclosed in the Chinese utility model patent with announcement number CN219073238U drives the scraper to rotate through a fixed sleeve and a connecting assembly. The fixing screw can realize the disassembly of the fixed sleeve and the hollow rotating shaft of the scraper. The rotation of the scraper can scrape out the foam on the top of the slurry in the flotation machine housing to complete the flotation work. The push-pull power assembly pushes and pulls the sliding sleeve along the hollow rotating shaft of the scraper. The U-shaped scraper bar can be driven to move on the side of the scraper through the extension rod and the disassembly assembly. The condensed slurry on the side of the scraper can be scraped off by the U-shaped scraper bar to achieve the cleaning of the scraper.

[0004] For this structure, although the scraper can be cleaned by the push-pull power assembly, the push-pull power assembly needs to be regularly maintained to ensure the cleaning effect of the scraper, and the operation is not convenient. Therefore, we propose a flotation machine scraper cleaning device that does not require frequent maintenance, reduces the workload of operators, and improves the working efficiency of the flotation machine.

Under its restriction, when the roller rotates, the contracted scraper can be thrown out to perform flotation work.

[0011] Preferably, there are four I-shaped counterweights distributed around the center of the roller. Under the action of the gravity of the I-shaped counterweights, the limit plate is pulled into the inside of the sleeve frame, causing the scraper to slide into the inside of the sleeve frame.

[0012] Preferably, the outer wall of the limit plate is slidably arranged with the inner wall of the sleeve frame, and the outer wall of the scraper is slidably arranged with the inner wall of the sleeve frame. Under the scraping of the scraper frame, the surface of the scraper sliding toward the inside of the sleeve frame can be cleaned.

[0013] Preferably, the outer wall of the limiting ring is slidably arranged with the inner wall of the sleeve, and the sliding rod is slidably arranged with the inside of the sleeve. Under the restriction of the limiting ring, the sliding rod can be prevented from sliding out of the inside of the sleeve.

[0014] Preferably, the outer wall of the scraper frame is arranged in an inclined surface, and the outer wall of the scraper frame is coated with an anti-stick coating, under which the scraper can be cleaned while preventing impurities from adhering, so as to improve the cleaning effect of the scraper.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The flotation machine scraper cleaning device is composed of a cleaning component. When the scraper in the flotation machine needs to be cleaned, the rotating shaft is rotated, and the rotating shaft drives the roller to rotate accordingly. Under the action of centrifugal force, the limit groove opened on the outer wall of the scraper slides on the outer wall of the limit block fixedly installed on the inner side of the slide frame, and the I-shaped counterweight slides inside the sleeve frame under the action of centrifugal force and gravity, pushing the limit plate, so that the limit plate and the scraper are thrown out from the sleeve frame. At this time, the scraper can perform flotation work. As the scraper rotates, the sleeve frame is away from the flotation tank. At this time, the I-shaped counterweight It slides toward the inside of the frame, driving the limit plate to slide accordingly, and the scraper slidingly arranged on the inner side of the limit plate slides toward the inside of the frame accordingly, and the outer wall of the scraper contacts the scraper frame arranged on the outer wall of the frame. Under the restriction of the scraper frame, the impurities attached to the outer wall of the scraper are scraped and cleaned. Under the action of gravity, the structure drives the scraper to slide toward the inside of the frame through the I-shaped counterweight block, and the outer wall of the scraper is automatically cleaned through the scraper frame without the help of external work for cleaning, thereby reducing the maintenance work of the operator, and under the action of centrifugal force, the scraper can be thrown out of the frame for flotation work.

[0017] 2. The flotation machine scraper cleaning device is composed of an anti-sticking component as one of its components. When the scraper needs to be cleaned, when the scraper slides toward the inside of the sleeve frame, the outer wall of the scraper slides and contacts with the inner wall of the scraper frame. Under its restriction, impurities attached to the outer wall of the scraper can be cleaned. When the impurities contact the scraper frame, they are squeezed with the scraper frame, so that the sliding rod fixedly installed on the outer wall of the scraper frame drives the limit ring to slide toward the inside of the sleeve and compresses the spring. When the scraper frame is cleaned, the spring is not squeezed at this time. Under the action of its elasticity, the scraper frame is pushed away from the sleeve frame, so that the scraper frame produces a polarization effect, so as to reduce impurities attached to the outer wall of the scraper frame, so that the scraper cleaning effect of the scraper frame is better.

At this time, the scraper 416 can perform flotation work. With the rotation of the scraper 416, the sleeve frame 411 is away from the flotation tank. At this time, the I-shaped counterweight 412 slides toward the inside of the sleeve frame 411. The scraper 416 is moved, driving the limit plate 413 to slide accordingly, and the scraper 416 slidingly arranged on the inner side of the limit plate 413 slides toward the inside of the sleeve frame 411, and the outer wall of the scraper 416 contacts the scraper frame 425 arranged on the outer wall of the sleeve frame 411.
