Description

Technical Field

[0001] This utility model relates to the field of flotation machine technology, specifically to a wet flotation machine for coal gangue separation. Background Technology

[0002] Flotation is a technique for separating valuable minerals from ores based on the differences in the physicochemical properties of mineral particles. It is one of the most widely used production processes in mineral processing. Flotation is usually carried out in a flotation machine. In the flotation machine, the slurry, after being treated with reagents, is agitated and aerated, causing some mineral particles to selectively adhere to the air bubbles and float to the surface of the slurry, where they are scraped off to form a froth product. The remaining particles remain in the slurry, thus achieving the purpose of mineral separation. During the flotation process, minerals with weak adhesion gradually detach from the air bubbles and sink, forming tailings; while valuable metallic minerals with stronger adhesion rise with the air bubbles.

[0003] Chinese utility model patent application number 202222747110.7 provides a mineral flotation machine. After a large amount of foam is generated on the surface of the slurry, the inclined part of the scraper is inserted into the liquid by activating the electric telescopic rod. The first motor is started, which drives the lead screw to rotate, thereby moving the movable block along the direction of the lead screw, and then moving the scraper to scrape the foam and concentrate in the foam above the liquid onto the vertical and inclined parts and discharged from the foam outlet. Then the electric telescopic rod extends and retracts, the scraper is separated from the liquid, the first motor drives the electric telescopic rod back to the initial position, and then the next discharge operation is performed.

[0004] However, during the use of the aforementioned equipment, it was found that the slurry contained various mineral particles, reagents, and water. Some hydrophobic mineral particles would adhere to the bubbles during the flotation process, forming mineralized bubbles. When the scraper scraped off the froth layer, the mineral particles in these mineralized bubbles would easily adhere to the scraper surface. This would prevent the scraper from successfully separating the froth layer from its surface, leaving some froth residue on the scraper surface. Consequently, the useful minerals that should have been scraped off remained in the slurry during subsequent flotation processes, reducing the flotation recovery rate. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wet flotation machine for coal gangue separation, which solves the problem mentioned in the background technology that when the scraper scrapes the foam layer, mineral particles in the mineralized bubbles tend to adhere to the scraper surface, which prevents the scraper from successfully separating the foam layer from the scraper surface.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wet flotation machine for coal gangue separation, comprising a flotation machine body, a slot on one side of the flotation machine body, a collection trough installed at the bottom outer side of the slot, a pushing assembly on the top of the flotation machine body, the pushing assembly including a push plate and a mounting plate, the mounting plate being positioned above the slot, a cleaning assembly installed on the outer side of the mounting plate, the cleaning assembly including a fixed frame, a lifting frame installed on the top of the fixed frame, a lifting plate slidably mounted on the lifting frame, the lifting plate being helically connected to a threaded rod, the threaded rod being rotatably mounted on the fixed frame, and a motor being connected to one end of the threaded rod, a connecting rod being fixedly mounted at the bottom of the lifting plate, and a cleaning component being connected to the bottom of the connecting rod.

[0007] Preferably, the pushing assembly includes a second motor, the output end of which is connected to a second threaded rod. The second threaded rod is rotatably mounted on the inner side of the mounting plate. Parallel sliding rods are arranged on both sides of the second threaded rod, and a movable frame is slidably mounted on the sliding rods. The movable frame is helically connected to the second threaded rod, and the push plate is located below the movable frame.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please see Figures 1-4 This utility model provides a wet flotation machine for coal gangue, including a flotation machine body 1. A slot 11 is opened on one side of the flotation machine body 1. A collection trough 2 is installed at the bottom of the outer side of the slot 11. A pushing component 3 is provided on the top of the flotation machine body 1. The pushing component 3 includes a push plate 36 and a mounting plate 37. The mounting plate 37 is located above the slot 11. A cleaning component 4 is installed on the outer side of the mounting plate 37. The cleaning component 4 includes a fixed frame 41. A lifting frame 42 is installed on the top of the fixed frame 41. A lifting plate 47 is slidably installed on the lifting frame 42. The lifting plate 47 is spirally connected to a threaded rod 44. The threaded rod 44 is rotatably installed on the fixed frame 41. At the same time, a motor 46 is connected to one end of the threaded rod 44. A connecting rod 43 is fixedly installed at the bottom of the lifting plate 47. A cleaning component 45 is connected to the bottom of the connecting rod 43.

[0022] The pushing component 3 includes a second motor 31, the output end of which is connected to a second threaded rod 33. The second threaded rod 33 is rotatably mounted on the inner side of the mounting plate 37. Slide rods 32 are arranged parallel to each other on both sides of the second threaded rod 33. A movable frame 34 is slidably mounted on the slide rods 32. The movable frame 34 is helically connected to the second threaded rod 33. The push plate 36 is located below the movable frame 34.

[0023] An electric telescopic rod 35 is installed above the movable frame 34. The output end of the electric telescopic rod 35 passes through the movable frame 34 and is connected to the push plate 36.

[0024] Specifically, the slurry containing coal gangue is transported to the flotation machine body 1. The slurry contains various mineral particles, reagents and water. Some hydrophobic mineral particles will adhere to the air bubbles under the action of flotation reagents to form mineralized air bubbles. These mineralized air bubbles will float on the surface of the slurry to form a foam layer.

[0025] The motor 31 in the drive assembly 3 is activated, and the output end of the motor 31 drives the threaded rod 33 to rotate. Since the moving frame 34 is helically connected to the threaded rod 33 and the moving frame 34 slides on the slide rod 32, which acts as a guide, the rotation of the threaded rod 33 will cause the moving frame 34 to move linearly along the slide rod 32.

[0026] The pusher plate 36 is located below the movable frame 34. The movement of the movable frame 34 will drive the pusher plate 36 to move together. At the same time, the height of the pusher plate 36 can be adjusted by the electric telescopic rod 35 so that its lower end just contacts the foam layer on the surface of the slurry. During the movement, the pusher plate 36 pushes the foam layer on the surface of the slurry toward the slot 11 opened on one side of the flotation machine body 1. The foam layer falls into the collection tank 2 installed at the bottom of the outer side through the slot 11, realizing the initial separation of useful minerals and slurry and completing the flotation process.

[0027] When the push plate 36 moves to the slot 11, the push plate 36 comes into contact with the cleaning component 45, activating the motor 46 in the cleaning assembly 4. The motor 46 drives the threaded rod 44 to rotate. Since the lifting plate 47 is helically connected to the threaded rod 44, and the lifting plate 47 slides on the lifting frame 42, which acts as a guide, the rotation of the threaded rod 44 will cause the lifting plate 47 to move up and down in a straight line along the lifting frame 42.

[0028] The up-and-down movement of the lifting plate 47 will drive the cleaning component 45 to move up and down through the connecting rod 43, so that the cleaning component 45 can remove the mineral particles in the mineralized bubbles adhering to the surface of the push plate 36 by scraping, wiping and other means, so that the attached mineral particles fall into the collection tank 2, ensuring the cleanliness of the surface of the push plate 36, so that the foam layer can be scraped smoothly next time.

[0029] Furthermore, to ensure the cleaning effect of cleaning component 45, please refer to... Figures 1-4 The cleaning component 45 includes a cleaning frame 453 with a C-shaped cross section. A scraper 452 is slidably installed inside the cleaning frame 453. A guide rod 451 is fixedly installed at one end of the scraper 452. One end of the guide rod 451 passes through the cleaning frame 453 and is connected to a limiting plate 454. The limiting plate 454 is connected to the cleaning frame 453 by a spring 455.

[0030] The cleaning component 45 is set at an angle.

[0031] Specifically, the scraper 452 in the cleaning component 45 is connected to the limiting plate 454 via the guide rod 451, and the limiting plate 454 is connected to the cleaning frame 453 via the spring 455. The spring 455 is elastic. When the scraper 452 contacts the surface of the push plate 36, the spring 455 will deform to provide an elastic force, so that the scraper 452 is pressed tightly against the surface of the push plate 36, thereby ensuring that the scraper 452 and the surface of the push plate 36 are well attached. Meanwhile, since a guide rod 451 is fixedly installed at one end of the scraper 452, the guide rod 451 passes through the cleaning frame 453 and is connected to the limiting plate 454. The limiting plate 454 is connected to the cleaning frame 453 through a spring 455. When the scraper 452 contacts the surface of the push plate 36, if there is a protrusion on the surface of the push plate 36, the protrusion will generate a reverse force on the scraper 452, causing the scraper 452 to drive the limiting plate 454 to stretch the spring 455. After being stretched, the spring 455 will produce elastic deformation and also generate a reverse elastic force. This elastic force will make the scraper 452 press tightly against the protruding surface of the push plate 36, ensuring the adhesion between the scraper 452 and the surface of the push plate 36, thereby ensuring the cleaning effect of the cleaning component 45.

[0032] The working principle involves conveying a slurry containing coal gangue into the flotation machine body 1. The slurry contains various mineral particles, reagents, and water. Under the action of the flotation reagents, some hydrophobic mineral particles adhere to air bubbles, forming mineralized bubbles. These mineralized bubbles float on the surface of the slurry, forming a foam layer. The motor 31 in the drive assembly 3 is activated. The output of the motor 31 drives the threaded rod 33 to rotate. The rotation of the threaded rod 33 causes the moving frame 34 to move linearly along the slide rod 32. The movement of the moving frame 34 moves the push plate 36 along with it. During this process, the height of the push plate 36 is precisely adjusted by the electric telescopic rod 35 so that its lower end just contacts the foam layer on the surface of the slurry. As the push plate 36 moves, it pushes the foam layer on the surface of the slurry towards the slot 11 on one side of the flotation machine body 1. The foam layer falls through the slot 11 into the collection tank 2 installed at the bottom outer side.

[0033] At this point, the pusher plate 36 is in contact with the cleaning component 45, and the motor 46 in the cleaning assembly 4 is activated. The motor 46 drives the threaded rod 44 to rotate. Therefore, the rotation of the threaded rod 44 causes the lifting plate 47 to move up and down linearly along the lifting frame 42. The up and down movement of the lifting plate 47 drives the cleaning component 45 to move up and down through the connecting rod 43. The cleaning component 45 removes mineral particles from the mineralized bubbles adhering to the surface of the pusher plate 36 by scraping and wiping, causing the adhering mineral particles to fall into the collection tank 2, ensuring the cleanliness of the surface of the pusher plate 36. After completing one flotation and pusher plate 36 cleaning cycle, the motor 31 reverses, causing the moving frame 34 and pusher plate 36 to return to their initial positions, ready for the next flotation operation. The above flotation and cleaning process is repeated to continuously perform wet separation of coal gangue slurry.
