Technical Field

[0001] The utility model relates to the field of mineral flotation equipment, in particular to a bubble scraping device of a flotation machine. Background Art

[0002] Flotation machine is an important equipment in the process of mineral selection. Its main function is to utilize the physical and chemical properties of the mineral itself and achieve separation through combination with reagents.

[0003] Flotation machines usually consist of a trough, scrapers, agitators, air inlet pipes, foam tanks and other parts. After the slurry enters the trough of the flotation machine and is stirred by the agitator, the negative pressure formed by the stirring will cause foam to be generated in the air inlet pipe in the water. At this time, the reagent will be adsorbed on the surface of the mineral, and the foam will also adhere to the surface of the mineral, so that the mineral particles and the foam are fixed together to form foam minerals. The foam minerals will float to the water surface. At this time, the scraper will scrape the foam minerals into the foam tank. The foam minerals in the foam tank form foam products, and the rest will remain in the slurry to achieve mineral separation.

[0004] The scraper of the existing flotation machine adopts the method of scraping by rotating the cylinder. The contact time between the scraper and the foam is short, and the scraper can only scrape the foam minerals at a specific position, thereby affecting the subsequent mineral flotation efficiency.

[0030] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0031] like Figure 1 、 Figure 2 and Figure 5 As shown, a flotation machine scraping device according to an embodiment of the present invention includes: a driving shaft 1000, a driven shaft 2000, a block conveyor belt 3000 and a scraper 4000;

[0032] The driven shaft 2000 is away from the driving shaft 1000. The driving shaft 1000 drives the driven shaft 2000 to rotate through the block conveyor belt 3000. The block conveyor belt 3000 includes a connecting rod 3100, a transmission block 3200 and a hinge block 3300. The transmission block 3200 and the hinge block 3300 are both provided with connecting holes 3230. The connecting rod 3100 passes through the connecting holes 3230 of multiple transmission blocks 3200 and the hinge block 3300 to form the block conveyor belt 3000. Grooves are provided on both sides of the transmission block 3200 so that the slots 3400 at both ends of the transmission block 3200 cooperate with the driving shaft 1000 and the driven shaft 2000. The scraper 4000 is provided on the hinge block 3300.

[0033] The hinge block 3300 includes a first hinge hole 3310 and a hinge shaft 3320. The hinge shaft 3320 passes through the first hinge hole 3310 and is disposed on the hinge block 3300.

[0034] The scraper 4000 includes a first portion 4100 and a second portion 4200. The first portion 4100 is longer than the second portion 4200. The first portion 4100 is perpendicularly connected to the second portion 4200. A second hinge hole 4300 is provided at the connection between the first portion 4100 and the second portion 4200. The scraper 4000 is mounted on the hinge shaft 3320 through the second hinge hole 4300.

[0035] Among them, it is necessary to first insert the connecting protrusion 3210 of the previous transmission block 3200 into the connecting groove 3220 of the next transmission block 3200, and repeat the installation of multiple transmission blocks 3200 in sequence. When installing multiple transmission blocks 3200, a hinge block 3300 can be inserted. The connection method is to use the connecting rod 3100 to penetrate the connecting groove 3220 and the connecting hole 3230 of the connecting protrusion 3210, thereby connecting two transmission blocks 3200 or connecting a transmission block 3200 and a hinge block 330. 0, finally forming the block conveyor belt 3000, wherein the slots 3400 at both ends of the transmission block 3200 match the gear teeth on the driving shaft 1000 and the driven shaft 2000. After completing the installation of the block conveyor belt 3000, the scraper 4000 is installed on the hinge block 3300. First, the hinge shaft 3320 is inserted into the first hinge hole 3310, and then inserted into the second hinge hole 4300 of the scraper 4000 and fixed. At this time, the scraper 4000 is hinged on the hinge block 3300.

[0036] When a user needs to use the flotation machine scraping device of the present invention to scrape the mineral foam suspended on the water surface in the flotation machine, as shown in the figure, the motor drives the driving shaft 1000 to rotate clockwise, thereby driving the entire block conveyor belt 3000 and multiple scrapers 4000 to move, wherein the first part 4100 of the scraper 4000 away from the flotation machine liquid surface 9000 contacts the block conveyor belt 3000. When the block conveyor belt 3000 gradually approaches the flotation machine liquid surface 9000, the first part 4100 of the scraper 4000 is too long and its own gravity is large, so that the first part 4100 of the scraper 4000 flips into the liquid surface through the hinge, and the scraper 4000 continues to push the mineral foam on the flotation machine liquid surface 9000 forward through the block conveyor belt 3000. When the first part 4100 of the scraper 4000 pushes the flotation machine liquid surface 9000, Resistance will be generated, causing the second part 4200 of the scraper 4000 to contact and offset the resistance of the block conveyor belt 3000, ensuring that the first part 4100 of the scraper 4000 can stably scrape the mineral foam, so that the scraper 4000 can scrape the mineral foam below the driving shaft 1000 to the driven shaft 2000. When the scraper 4000 reaches the driven shaft 2000, it will move upward. At this time, the first part 4100 of the scraper 4000 gradually tilts, scraping the mineral foam on the liquid surface into the flotation machine trough 8000 near the driven shaft 2000. After the scraper 4000 reaches a certain height after completing the scraping, the first part 4100 of the scraper 4000 is again attached to the block conveyor belt 3000 through the hinge due to gravity, waiting for the scraper 4000 to move back to the driving shaft 1000 and re-enter the flotation machine liquid surface 9000 to continue scraping.

[0037] Further, if Figure 3 As shown, in the second embodiment of the present invention, the flotation machine's bubble scraping device further includes a counterweight 5000, which is disposed on the second portion 4200. When the scraper 4000 passes the driving shaft 1000, the counterweight 5000 is provided to accelerate the vertical descent of the first portion 4100 of the scraper 4000. Simultaneously, when the scraper 4000 passes the driven shaft 2000, the counterweight quickly presses down the first portion 4100 of the scraper 4000, causing the scraper 4000 to return to its initial position.

[0038] Further, if Figure 4As shown, in the third embodiment of the present invention, the flotation machine's froth scraping device further includes a rib plate 6000, one end of which is mounted on the second portion 4200, and the other end of which is mounted on the counterweight 5000. As the scraper 4000 continuously scrapes mineral froth from the flotation machine's liquid level 9000, the first portion 4100 of the scraper 4000 continuously experiences resistance from the liquid level. The second portion 4200 of the scraper 4000, in contact with the block conveyor belt 3000, continuously provides a counteracting force. However, the first portion 4100 of the scraper 4000 is too long and prone to deformation over time. The provision of the rib plate 6000 further stabilizes the first portion 4100, thereby extending the service life of the scraper 4000.

[0039] Furthermore, the first part 4100 is provided with a plurality of scraping grooves, and the cross section of the scraping grooves is arc-shaped. By providing a plurality of scraping grooves on the surface of the first part 4100 that contacts the liquid surface, it is convenient to scrape the mineral foam.

[0040] Further, if Figure 6 As shown, the flotation machine's scraping device also includes a flushing assembly, which includes a fixed frame 7200 and a flushing nozzle 7100. The fixed frame 7200 is located near the driven shaft 2000, and the flushing nozzle 7100 is mounted on the fixed frame 7200. After prolonged use, the flotation machine requires cleaning and maintenance. In this case, the flushing assembly can be used to clean the scraping surface of the first portion 4100 of the scraper 4000.
