Description

Technical Field

[0001] This utility model relates to the technical field of coal slime flotation equipment, and more specifically, to a flotation cell for a stirred coal slime flotation device. Background Technology

[0002] The coal slime flotation cell is a key piece of equipment used for coal slime flotation. It utilizes the difference in hydrophobicity between the surfaces of coal and impurities such as gangue. Under the action of flotation reagents, coal particles adhere to air bubbles, float to the surface of the slurry, form a foam layer, and are scraped off, thus separating from the impurities. Its structure includes the tank body, agitation mechanism, and aeration device. It features high-efficiency separation and strong adjustability, and is widely used in the coal washing industry, playing a significant role in improving coal quality and recovering clean coal.

[0003] Publication No. (CN221360432U) discloses a flotation tank body for a flotation machine, including a housing. Screws are symmetrically and rotatably connected to both sides of the housing. A first bevel gear is fixedly connected to one end of each screw. The first bevel gear meshes with a second bevel gear. A first rotating shaft is fixedly connected between the second bevel gears. A slider is threaded onto each screw. A rotating rod is rotatably connected between the sliders. Multiple scrapers are fixedly connected to the outer wall of the rotating rod. A first gear is fixedly connected to the output end of a second motor. The first gear meshes with a second gear. A second rotating shaft is fixedly connected to one end of the second gear. A flow stabilizer is fixedly connected to the second rotating shaft. This invention allows the scrapers to move to different positions within the flotation tank while rotating, thereby improving flotation efficiency. Furthermore, adjusting the flow stabilizer to different angles can accommodate different flow rates.

[0004] However, the flotation tank of this flotation machine has the following drawbacks: when it is adjusted and moved, it cannot efficiently stir the inside to make it fully mixed, and when it is moved and adjusted to scrape it, it will scrape away the liquid and foam at the same time. After a long time of scraping, the water level will drop and the foam will not be effectively scraped away. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a flotation cell for a stirred coal slime flotation device, so as to solve the problem that the prior art cannot separate liquid and foam while efficiently removing foam.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flotation cell for a stirred coal slime flotation device, comprising...

[0007] The main body has a support plate fixedly connected to its exterior. A motor is fixedly connected to the exterior of the support plate. A rotating wheel is fixedly connected to the drive end of the motor. A rotating column is rotatably connected to the inner wall of the main body. A transmission wheel is fixedly connected to the exterior of the rotating column. A belt is fitted between the rotating wheel and the transmission wheel. Multiple connecting blocks are fixedly connected to the exterior of the rotating column. A housing is fixedly connected to the end of the multiple connecting blocks away from the rotating column. A push plate is slidably connected to the inner wall of the housing. A push block is fixedly connected to the exterior of the push plate. A filter rod is fixedly connected to the inner wall of the push block. A rubber strip is fixedly connected to the end of the push block away from the push plate. A spring is fixedly connected to the end of the push plate away from the push block. A drive assembly for driving subsequent components is fixedly connected to the exterior of the support plate.

[0008] The drive assembly includes a second motor, which is fixedly connected to the outside of the support plate. A drive column is fixedly connected to the drive end of the second motor. A guide plate is fixedly connected to the outside of the drive column. A blade is fixedly connected to the outside of the drive column. Multiple holes are provided on the outside of the blade. A cover plate is movably connected to the outside of the drive column. A flow hole is provided on the inner wall of the cover plate. A fixing block is fixedly connected to the outside of the main body. A V-shaped channel is provided on the inner wall of the fixing block.

[0009] The end of the spring away from the push plate is fixedly connected to the inner wall of the housing, and the end of the rubber strip away from the push block is in contact with the inner wall of the main body.

[0010] The outer side of the drive column contacts the inner wall of the support plate, and the outer side of the cover plate is movably connected to the inner wall of the main body.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In the above scheme, the starting motor drives the rotating column to rotate via a belt, which in turn drives the outer shell to rotate synchronously. When the rubber strip inside the outer shell contacts the outside of the main body, it squeezes the push plate to compress the spring, facilitating the smooth passage of the rubber strip and greatly improving the efficiency of foam filtration. The push block is equipped with a filter rod, which allows the liquid to flow out from the gap when scraping the foam, leaving only the foam, effectively improving the flotation quality and efficiency.

[0013] In the above scheme, by setting up a drive assembly and starting motor two, the drive column rotates accordingly, driving the paddle and the inclined guide plate to rotate. The guide plate guides the liquid powerfully into the flow hole of the cover plate, and the paddle rotates in the liquid, generating a large number of bubbles due to its internal pores. Inside the main body, there are fixed blocks around the drive column. Under the action of the liquid's residual wave, the liquid quickly passes through the V-shaped channels of the fixed blocks to generate gas, greatly improving production efficiency.

Detailed Implementation

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] As attached Figure 1 To be continued Figure 5 An embodiment of this utility model provides a flotation cell for a stirred coal slime flotation device, including...

[0023] The main body 1 is externally fixedly connected to a support plate 2. The main body 1 serves as the primary load-bearing structure of the entire flotation cell, accommodating coal slime and various substances involved in the flotation process. The support plate 2 provides support, ensuring the stability of the entire device. A motor 3 is externally fixedly connected to the support plate 2. Motor 3 is the power source and foundation for rotating the rotating column 7. A rotating wheel 4 is fixedly connected to the drive end of motor 3, rotating under the drive of motor 3. The rotating column 7 is rotatably connected to the inner wall of the main body 1, providing a base for rotation. A transmission wheel 6 is externally fixedly connected to the rotating column 7, cooperating with the rotating wheel 4 to transmit power. A belt 5 is fitted between the rotating wheel 4 and the transmission wheel 6, serving as the connecting component and transmitting the power from motor 3 to the rotating column 7, enabling it to rotate according to a predetermined pattern. Multiple connecting blocks 8 are fixedly connected to the outside of the rotating column 7. These connecting blocks 8 connect the rotating column 7 to the outer casing 9, allowing the outer casing 9 to rotate together with the rotating column 7. The outer casing 9 is fixedly connected to the end of each connecting block 8 away from the rotating column 7. A push plate 10 is installed inside the outer casing 9, rotating under the influence of the rotating column 7 to process foam. The push plate 10 is slidably connected to the inner wall of the outer casing 9, sliding and acting when the rubber strip 12 is compressed. A push block 11 is fixedly connected to the outside of the push plate 10, moving under its influence and primarily used to scrape foam. A filter rod 23 is fixedly connected to the inner wall of the push block 11, filtering the liquid and retaining only the foam when the push block 11 scrapes it. A rubber strip 12 is fixedly connected to the end of the push block 11 away from the push plate 10, contacting the inner wall of the main body 1. During rotation, the rubber strip 12 is compressed, causing the push plate 10 to move. A spring 13 is fixedly connected to the end of the push plate 10 away from the push block 11. When the rubber strip 12 is squeezed, the spring 13 plays a role in buffering and resetting, so that the push plate 10 and the push block 11 can perform normal working cycles.

[0024] The drive assembly includes a second motor 14, which is the core power source of the drive assembly, providing power for the rotation of the drive column 15, thereby driving the entire drive assembly. The second motor 14 is externally fixedly connected to the support plate 2, which provides fixation and support, ensuring the stability of the second motor 14 during operation. The drive column 15 is fixedly connected to the drive end of the second motor 14. Driven by the second motor 14, the drive column 15 rotates and is a key component connecting the second motor 14, transmitting power. A guide plate 16 is externally fixedly connected to the drive column 15. The guide plate 16 is installed at an inclined angle on the drive column 15, guiding the liquid forcefully into the flow holes 20 in the cover plate 19 when the drive column 15 rotates, promoting liquid flow and mixing. A paddle 17 is externally fixedly connected to the drive column 15. Driven by the drive column 15, the paddle 17 rotates in the liquid, generating a stirring effect through its rotation, and its internal holes 18 generate a large number of bubbles, promoting the flotation process. Multiple holes 18 are provided on the exterior of the paddle 17. The presence of these holes 18 allows the paddle 17 to generate a large number of bubbles when rotating. These bubbles interact with the substances in the coal slime, improving the flotation effect. A cover plate 19 is movably connected to the exterior of the drive column 15. The cover plate 19 can move outside the drive column 15, providing protection and guiding the liquid flow. The flow holes 20 inside the cover plate 19 are closely related to the liquid flow. Flow holes 20 are provided on the inner wall of the cover plate 19, serving as channels for liquid entry and exit. Guided by the guide plate 16, the liquid enters a specific area through the flow holes 20 to participate in the flotation process. A fixing block 21 is fixedly connected to the exterior of the main body 1. The fixing block 21 is fixed to the exterior of the main body 1. During the flotation process, it is affected by the residual force of the liquid, providing some assistance to the liquid flow and bubble generation. The inner wall of the fixed block 21 is provided with V-shaped channels 22. The presence of V-shaped channels 22 allows gas to be generated when the liquid passes through quickly, further increasing the amount of gas generated during the flotation process, thereby improving production efficiency.

[0025] The end of spring 13 away from push plate 10 is fixedly connected to the inner wall of housing 9. This connection allows spring 13 to compress and extend when push plate 10 is subjected to external force, playing a buffering and restoring role, ensuring the normal operation of push plate 10 and push block 11. The end of rubber strip 12 away from push block 11 is in contact with the inner wall of main body 1. When housing 9 rotates with rotating column 7, rubber strip 12 contacts and is squeezed against the inner wall of main body 1, thereby driving push plate 10 to achieve the function of scraping foam.

[0026] The outer side of the drive column 15 contacts the inner wall of the support plate 2. The support plate 2 provides support and positioning for the drive column 15, ensuring its stability during rotation and enabling it to accurately drive the guide plate 16. The outer side of the cover plate 19 is movably connected to the inner wall of the main body 1. The cover plate 19 moves within the inner wall of the main body 1, ensuring that its internal flow holes 20 cooperate with the flow of liquid, and also providing space and protection for the rotation of the drive column 15.

[0027] The working process of this utility model is as follows:

[0028] First, the starter motor 3 drives the rotating column 7 to rotate via the belt 5. When the rotating column 7 rotates, it also drives the outer shell 9 to rotate. When the rubber strip 12 in the outer shell 9 comes into contact with the outside of the main body 1, the rubber strip 12 will squeeze the spring 13 inside the outer shell 9 through the push plate 10. The spring 13 will be compressed to allow the rubber strip 12 to slide across the outside of the main body 1, improving the efficiency of foam filtration. Furthermore, the push block 11 is equipped with a filter rod 23, so when the push block 11 scrapes the foam, it will carry some liquid with it. The liquid will flow out from the gap between the filter rod 23 and the push block 11, only scraping away the foam, thus improving the flotation quality and efficiency.

[0029] By starting the motor 14, the drive column 15 is rotated, which in turn drives the blade 17 and the guide plate 16 to rotate. The guide plate 16 is installed in the drive column 15 at an inclined angle, which causes the liquid to enter the flow hole 20 in the cover plate 19 with force, causing the blade 17 to rotate inside the liquid. The blade 17 has holes 18 inside, so a large number of bubbles are generated. The main body 1 has a fixing block 21 inside. The fixing block 21 is located around the drive column 15 and is affected by the residual force of the liquid. The liquid passes through the V-shaped channel 22 in the fixing block 21 quickly, which generates gas inside the liquid and improves production efficiency.
