Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of slime flotation machines, and particularly relates to a slime flotation machine. Background Art
[0002] The working principle of a flotation machine is based on the rotation of an impeller driven by an electric motor, which generates a centrifugal force to form a negative pressure, thereby sucking in sufficient air to mix with the pulp. After adding reagents, the impeller stirs the pulp and the reagents to mix, and also refines the foam, causing the minerals to adhere to the foam and float to the surface of the pulp to form mineralized foam. In order to control the output of the foam, visual information during the flotation process is obtained through a machine vision algorithm. This information directly reflects the flotation working conditions and process indicators, and the machine vision technology is used to process the foam image information online, establish a flotation process model based on the visual characteristics of the foam, and realize real-time monitoring and optimized control of the flotation process, improving the efficiency and output of the flotation process. After the pulp is flotated, the machine vision technology analyzes the tailings and then discharges the flotated tailings out of the machine body.
[0003] Currently, when a slime flotation machine scrapes the mineralized foam out of the machine body, the mineralized foam will adhere to the panel in the lower half area of the scraper of the slime flotation machine.

Detailed implementation manners
[0028] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0029] Embodiment 1:
[0030] As Figure 1As shown in the figure, a slime flotation machine in an embodiment of the present utility model includes a machine body 1 filled with pulp. A first motor 11 and a second motor 12 are installed on the machine body 1. An impeller is welded on the rotating shaft of the first motor 11. A belt is sleeved on the second motor 12, and one end of the belt away from the second motor 12 is sleeved on a rotating rod 2. When the second motor 12 rotates, the rotating rod 2 is driven to rotate through the belt. A fixing ring 21 is welded on the rotating rod 2, a pair of fixing plates 22 are welded on the fixing ring 21, a connecting column 23 is welded on the panel at one end of the fixing plate 22 away from the fixing ring 21, and a scraping plate 3 is welded on the connecting column 23.
[0031] Specifically, bearing seats 13 are respectively welded on both side walls of the machine body 1, and a slewing bearing is installed on the bearing seats 13. The rotating rod 2 passes through the slewing bearing on the bearing seats 13 and is rotatably connected to the bearing seats 13. When the slime flotation machine works, the second motor 12 rotates to drive the rotating rod 2 to rotate, and the scraping plate 3 on the rotating rod 2 rotates simultaneously to scrape the mineralized foam in the machine body 1 out of the machine body 1. A sensor is arranged in the machine body 1 to detect different components and corresponding physical differences in the ore. By obtaining data through the sensor, the machine vision algorithm can perform high-speed imaging and real-time recognition and analysis on the ore, and will continuously observe the state of the slime. After the separation amount of substances in the slime reaches the standard, the slime tailings in the machine body 1 are discharged. The application of this technology not only improves the resource utilization efficiency but also helps to reduce environmental pollution.
[0032] When the scraping plate 3 scrapes out the mineralized foam, a part of the mineralized foam will adhere to the panel in the lower half area of the scraping plate 3. When the scraping plate 3 rotates into the machine body 1 again, the mineralized foam falls into the machine body 1, affecting the efficiency of the scraping plate 3 to scrape out the mineralized foam.
[0033] In order to remove the mineralized foam on the panel in the lower half area of the scraping plate 3, as Figures 2 to 5 shown, a foam scraping assembly is fixedly connected to the machine body 1. The foam scraping assembly includes brackets 4. There are a pair of brackets 4, and a first elastic strip 5 is wound on the pair of brackets 4. The first elastic strip 5 is used to scrape the foam on the scraping plate 3, and an elastic block 24 is adhered to the scraping plate 3. The elastic block 24 is used to adjust the angle of the scraping plate 3.
[0034] Specifically, a through groove 401 is formed in the bracket 4, and a sliding column 6 is slidably connected in the through groove 401 on the bracket 4. The sliding column 6 penetrates through the through groove 401 on the bracket 4. A first limiting ring 61 is integrally formed on the sliding column 6. The first limiting rings 61 are in a pair, and a pair of second limiting rings 62 are integrally formed on the two end faces of the sliding column 6 respectively. A limiting groove 63 is formed between the first limiting ring 61 and the second limiting ring 62, and the first elastic strip 5 is wound in the limiting groove 63 on one side of the inner wall of the bracket 4. The opposite side walls of the two first limiting rings 61 can limit the sliding column 6, so that the sliding column 6 can stably slide in the through groove 401. One end of the elastic block 24 is bonded to the scraping plate 3, and the end of the elastic block 24 away from the scraping plate 3 is bonded to the connecting column 23.
[0035] When the scraping plate 3 rotates on the machine body 1 following the rotating rod 2, the end face of the scraping plate 3 will contact the first elastic strip 5. Under the continuous rotation of the scraping plate 3, the first elastic strip 5 undergoes elastic deformation, driving the sliding column 6 to move upward in the through groove 401. At the same time, the elastic block 24 will also deform after being pressed, causing the angle of the scraping plate 3 to tilt.
[0036] The bracket 4 continues to rotate, and the sliding column 6 will also slide upward in the through groove 401, so that the first elastic strip 5 gradually moves from the middle of the scraping plate 3 to the outside of the scraping plate 3, scraping off the mineralized foam adhered to the scraping plate 3. When the first elastic strip 5 disengages from the surface of the scraping plate 3, the sliding column 6 falls back to the bottom wall of the through groove 401 under the action of gravity, and the first elastic strip 5 returns to its original position, and then it can scrape off the mineralized foam adhered to the continuously rotating scraping plate 3. The scraped mineralized foam will fall into the receiving groove beside the machine body 1 (not shown in the figure) and will not enter the machine body 1 again, thereby improving the ability of the scraping plate 3 to scrape off the mineralized foam and enhancing the production efficiency of the coal slime flotation machine.
[0037] Preferably, the material of the first elastic strip 5 is TPEE, which has excellent fatigue resistance and bending resistance and can be used for a long time without breaking.
[0038] It should be noted that when dirt adheres to the through groove 401, the sliding column 6 cannot fall from a high position in the through groove 401 under the action of gravity, resulting in the first elastic strip 5 being unable to return to its original position, and the first elastic strip 5 loses the ability to scrape off the mineralized foam on the scraping plate 3.
[0039] Further, a rope post 41 is welded on one side of the bracket 4, and a second elastic strip 7 is wound around the rope post 41 and a limiting groove 63 on one side of the outer wall of the bracket 4. When the sliding column 6 moves upward in the through groove 401, the second elastic strip 7 is stretched. When the first elastic strip 5 detaches from the scraper 3, the second elastic strip 7 elastically contracts to return the sliding column 6 to its original position. At the same time, the pulling force of the second elastic strip 7 on the sliding column 6 can also make the first elastic strip 5 fit more tightly with the surface of the scraper 3, scrape the mineralized foam adhered to the scraper 3 more cleanly, and the contraction force of the second elastic strip 7 causes the sliding column 6 to return to its original position quickly. When the sliding column 6 contacts the bottom wall of the through groove 401, it will stop moving instantly, and the inertia generated can shake off the mineralized foam on the first elastic strip 5, ensuring the cleanliness of the first elastic strip 5 and being more conducive to scraping the mineralized foam from the scraper 3.
[0040] Embodiment 2:
[0041] As Figure 2 、 Figure 6 and Figure 7 shown, a rotating ball 231 is welded on the connecting column 23, and a rotating cap 232 is rotatably connected to the rotating ball 231. A seat body 31 is welded on the scraper 3, and the rotating cap 232 is snap-fitted into the seat body 31.
[0042] Specifically, when the scraper 3 rotates to contact the first elastic strip 5, the first elastic strip 5 elastically deforms and simultaneously drives the sliding column 6 to move upward in the through groove 401. After the scraper 3 is stressed, the rotating cap 232 rotates on the rotating ball 231 to form an inclined plane. When the scraper 3 continues to rotate, the first elastic strip 5 can scrape the mineralized foam adhered to the scraper 3 cleanly.
[0043] It should be noted that since the scraper 3 will be inclined after passing through the first elastic strip 5, in order not to affect the ability of the scraper 3 to scrape the mineralized foam out of the machine body 1, a spring 32 is welded on the scraper 3, and the end of the spring 32 away from the scraper 3 is welded on the fixed plate 22.
[0044] Specifically, when the scraper 3 is inclined after passing through the first elastic strip 5, the spring 32 can pull the scraper 3 back to be parallel to the fixed plate 22 to ensure the ability of the scraper 3 to scrape the mineralized foam out of the machine body 1.
[0045] During use, the second motor 12 rotates, driving the rotating rod 2 to rotate through a belt. When the rotating rod 2 rotates, the scraper 3 on the rotating rod 2 also rotates. When the scraper 3 comes into contact with the first elastic strip 5, the first elastic strip 5 presses against the surface of the scraper 3. As the scraper 3 continues to rotate, it exerts an upward force on the first elastic strip 5, and at the same time, the first elastic strip 5 also exerts a downward force on the scraper 3. After the first elastic strip 5 receives the upward force, it slides upward in the through groove 401 through the sliding column 6, and the scraper 3 also tilts downward. As a result, the first elastic strip 5 gradually moves towards the outer edge of the scraper 3 on the surface of the scraper 3, scraping off the mineralized foam adhered to the scraper 3. When the scraper 3 separates from the first elastic strip 5, the second elastic strip 7 pulls the sliding column 6 to make the sliding column 6 return to its original position, and the tilted scraper 3 also returns to its original position under the adjustment component for the next cycle.
