[0040] In the embodiment: the flotation device for ore dressing, when in use, the ore slurry liquid and the reagent in the flotation tank body 101 are mixed and stirred by the stirring mechanism 102, and the mineralization foam generated is floated on the top surface of the slurry liquid in the flotation tank body 101. When it is necessary to scrape out the foam;

[0041] Through the starting of the motor 201, the sprocket one 202 is driven to rotate. Since the chain 203 is engaged between the sprocket one 202 and the sprocket two 204, the movement of the chain 203 drives the roller one 210 to move. The roller one 210 is arranged in the sliding groove 209 of the mounting plate 208. When the roller one 210 moves, the mounting plate 208 is driven to move. The mounting plate 208 drives the two groups of sliding blocks 207 to slide on the slide rail 206. With the movement of the mounting plate 208, the scraper 103 is driven to move through the pin rod 211 and the rectangular block 212. The foam on the top of the ore slurry liquid is scraped out from the discharge port of the flotation tank body 101 by the scraper 103;

[0042] When the roller one 210 moves to the position of the sprocket one 202, under the action of the chain 203, the chain 203 drives the roller one 210 to move around the track of the sprocket one 202.

After the roller one 210 passes around the sprocket one 202, the mounting plate 208 drives the scraper 103 to move away from the discharge port of the flotation tank body 101;

[0043] At the same time, the electric push rod 301 is started, and the rod body 302 is driven to contract. The rod body 302 drives the lifting rod 303 to increase the distance from the top of the flotation tank body 101. At this time, the lifting rod 303 drives the straight rod to move upwards, the straight rod drives the scraper 103 to move upwards, and the scraper 103 drives the rectangular block 212 to slide on the pin rod 211, so that the bottom of the scraper 103 passes over the foam of the ore slurry liquid. Until the scraper 103 moves close to the inner wall of the flotation tank body 101, at the same time, the roller one 210 moves around the track of the sprocket two 204 and passes around the sprocket two 204. At this time, the electric push rod 301 is reset, and drives the rod body 302 and the lifting rod 303 to move downwards, and then drives the scraper 103 to reset. Then, the chain 203 drives the scraper 103 to continue to move towards the discharge port of the flotation tank body 101, so as to continue to scrape out the foam of the ore slurry liquid;

[0044] Through the operation, the scraper 103 is enabled to move all around on the top of the flotation tank body 101, the mineralized froth of the flotation tank body 101 can be scraped out at one time, the scraping range is enlarged, compared with the mineralized froth being briefly swept by the scraper 103 on the mineralized froth surface under the driving of the rotating rod, the scraping efficiency of the mineralized froth is improved, the flotation effect is improved, and the actual use requirement is met.

[0045] It should be noted that: the scheme further provides an electric control cabinet, the electric control cabinet is arranged on the flotation tank body 101, and each electrical equipment can be started respectively through the electric control cabinet in use. The power connection mode of each electrical equipment is an existing mature technology, which is a common technology in the field and will not be described in detail here.

[0046] Further,

[0047] In an optional embodiment, the surface of the straight rod is rotationally connected with the roller two 304 through a bearing.

[0048] In the embodiment, the roller two 304 on the straight rod can roll on the surface of the lifting rod 303, so that the contact friction between the straight rod of the scraper 103 and the lifting rod 303 is reduced.

[0049] The working principle and use process of the utility model: the ore dressing is with the flotation device, when using, through the agitating mechanism 102 to the ore pulp liquid and reagent mixing stirring inside the flotation cell main part 101, the mineralization foam produced at the same time floats on the pulp top surface of the flotation cell main part 101, when need to scrape out the foam;Through the starting of motor 201, and drive sprocket one 202 to rotate, because sprocket one 202 and sprocket two 204 have the chain 203 between the engagement, through the movement of chain 203, and then drive cylinder one 210 to move, and cylinder one 210 is arranged in the sliding slot 209 of mounting plate 208, while cylinder one 210 moves, and then drive mounting plate 208 to move, and mounting plate 208 drives two groups of sliding blocks 207 to slide on slide rail 206, along with the movement of mounting plate 208, and through the pin rod 211 and rectangular block 212 drive scraper 103 to move, through scraper 103 to scrape the foam on the top of ore pulp from the discharge port of flotation cell main part 101;When cylinder one 210 moves to the position of sprocket one 202, under the action of chain 203, chain 203 drives cylinder one 210 to move around the track of sprocket one 202, in this process, cylinder one 210 slides in the sliding slot 209 of mounting plate 208, until cylinder one 210 passes sprocket one 202, mounting plate 208 and drive scraper 103 to move away from the discharge port of flotation cell main part 101;At the same time, start electric push rod 301, and then drive rod body 302 to contract, and rod body 302 drives lifting rod 303 to increase the distance with the top of flotation cell main part 101, at this time, lifting rod 303 drives straight rod to move up, straight rod drives scraper 103 to move up, scraper 103 drives rectangular block 212 to slide on pin rod 211, so that the bottom of scraper 103 passes through the ore pulp foam, until scraper 103 moves close to the inner wall of flotation cell main part 101, at the same time, cylinder one 210 moves around the track of sprocket two 204, and passes sprocket two 204, at this time, electric push rod 301 resets, and drives rod body 302 and lifting rod 303 to move down, and then drive scraper 103 to reset, then through chain 203 drive scraper 103 to continue to move to the discharge port direction of flotation cell main part 101, to continue to scrape the ore pulp foam.
