Description

Technical Field

[0001] This utility model relates to the field of thickeners, and in particular to a high-efficiency thickener for red mud mines. Background Technology

[0002] A thickener is an important piece of equipment for solid-liquid separation, especially widely used in the mineral processing field. A red mud thickener is a solid-liquid separation device based on gravity settling, mainly used to treat red mud slurry generated during alumina production. Traditional thickeners are typically shallow, cylindrical tanks with a conical bottom, constructed of concrete or welded metal plates, capable of concentrating slurry with a solids content of 10%–20% into underflow slurry with a solids content of 45%–55%.

[0003] Existing red mud thickeners have low settling efficiency, insufficient capacity to process red mud slurry, and large fluctuations in underflow concentration, which makes the torque of the rake frame prone to overload, resulting in poor stability and low efficiency of the settling operation. This affects the quality of the red mud slurry settling operation and reduces the practicality of the thickener. Therefore, we propose a high-efficiency thickener for red mud mines to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-efficiency thickener for red mud mines.

[0005] The present invention solves its technical problem through the following technical solution: It includes a multi-cone sedimentation tank, a support plate fixed to the outer side of the multi-cone sedimentation tank, an installation platform fixed to the top of the support plate, a drive mechanism on the top of the installation platform, the drive mechanism including a motor mounting base, the motor mounting base being fixed to the top of the installation platform by bolts, a reduction motor being fixed to the top of the motor mounting base by bolts, a drive shaft being provided at the output end of the reduction motor, a feed hole being opened on the outer side of the drive shaft, a drive sleeve being fixed to the bottom of the drive shaft, a feeding mechanism being provided at the bottom of the installation platform, a filling mechanism being provided at the top of the feeding mechanism, and a scraping mechanism being provided on the outer side of the drive sleeve. The scraping mechanism includes a mounting ring, which is fixed to the outside of the drive sleeve by bolts. A hydraulic rod is fixed to the inner wall of the mounting ring, a drive sleeve is fixed to the bottom of the hydraulic rod, a rake frame is fixed to the outside of the drive sleeve, a mounting column is fixed to the bottom of the rake frame, a scraping rake is fixed to the bottom of the mounting column, and a discharge mechanism is provided at the bottom of the drive sleeve.

[0006] As a further improvement of this utility model, a control host is provided on the outside of the installation platform.

[0007] As a further embodiment of this utility model: the feeding mechanism includes a material collecting cylinder, which is fixed to the bottom of the installation platform by bolts. A feed pipe is fixed to the outside of the material collecting cylinder, and a support base is fixed to the outside of the feed pipe. The support base is fixedly connected to a support plate. A guide plate is fixed to the inner wall of the material collecting cylinder, and a connecting column is fixed to the bottom of the guide plate. A distribution plate is fixed to the bottom of the connecting column.

[0008] As a further embodiment of this utility model: the filling mechanism includes an installation pipe, which is fixed to the top of the installation platform by bolts. A material collection trough is fixed to the top of the installation pipe, and a feed nozzle is fixed to the top of the material collection trough. A connecting pipe is fixed to the outside of the installation pipe, and a support ring is fixed to the outside of the connecting pipe. The support ring is rotatably connected to the drive shaft.

[0009] As a further embodiment of this utility model: a material conveying pipe is fixed to the inner wall of the drive sleeve, and a spray arm is fixed to the outer side of the drive sleeve near the material conveying pipe.

[0011] As a further embodiment of this utility model: the discharge mechanism includes a drive motor, which is fixed to the inner wall of the drive sleeve by bolts. The output end of the drive motor is provided with a drive rod, and multiple guide blades are fixed on the outer side of the drive rod. A discharge pipe is fixed at the bottom of the multi-tapered sedimentation tank.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. Red mud slurry is injected into the multi-cone settling tank through the feeding mechanism. The packing mechanism adds flocculant to the red mud slurry at multiple points, which improves the sedimentation rate of the red mud slurry. The drive mechanism and scraping mechanism work together to scrape the sediment and guide it to the discharge mechanism. The discharge mechanism discharges the sediment. The multi-cone settling tank structure with a large cone at the bottom and a multi-cone transition in the middle can improve the concentration of the underflow. The up-and-down moving scraper can avoid torque overload of the scraper frame and scraper, ensuring the stability of the settling operation and improving the efficiency of the settling operation. This ensures the quality of the red mud slurry settling operation and improves the practicality of the thickener. 2. With the addition of a packing mechanism, flocculant is injected into the collection trough through the feed nozzle and then enters multiple installation pipes. This allows for multi-point flocculant addition during the feeding stage of the red mud slurry, facilitating the pre-mixing of the red mud slurry and flocculant. The flocculant is then sprayed onto the red mud slurry in the multi-cone settling tank via a spray arm, achieving a two-stage addition of flocculant. This ensures thorough mixing of the flocculant and the red mud slurry, thereby improving the settling speed of the red mud slurry. 3. By setting a limit slider to limit the up and down movement of the drive sleeve, the stability of the scraping operation is ensured. Attached Figure Description

[0018] Please see Figure 1-9This utility model provides a technical solution: it includes a multi-cone sedimentation tank 100, a support plate 110 fixed to the outside of the multi-cone sedimentation tank 100, an installation platform 120 fixed to the top of the support plate 110, a control host 130 arranged on the outside of the installation platform 120, a drive mechanism arranged on the top of the installation platform 120, the drive mechanism including a motor mounting base 210, a reduction motor 220 and a drive shaft 230, a feed hole 231 opened on the outside of the drive shaft 230, a drive sleeve 240 fixed to the bottom of the drive shaft 230, a feeding mechanism arranged at the bottom of the installation platform 120, a filling mechanism arranged at the top of the feeding mechanism, and a scraping mechanism arranged on the outside of the drive sleeve 240. The scraping mechanism includes an mounting ring 510, a hydraulic rod 520, and a drive sleeve 530. A rake frame 540 is fixed to the outer side of the drive sleeve 530, and a mounting column 541 is fixed to the bottom of the rake frame 540. A scraping rake 550 is fixed to the bottom of the mounting column 541. A discharge mechanism is provided at the bottom of the drive sleeve 240. The red mud slurry is injected into the multi-cone settling tank 100 through the feeding mechanism. The red mud slurry is treated with flocculant at multiple points through the packing mechanism, which improves the sedimentation rate of the red mud slurry. The drive mechanism and scraping mechanism work together to scrape the sediment and guide it to the discharge mechanism, which then discharges the sediment. The multi-cone sedimentation tank 100 structure, with its large-cone deep cone at the bottom and multiple cones in the middle, increases the concentration of the bottom flow. The vertically moving scraper 550 prevents torque overload on the scraper frame 540 and scraper 550, ensuring the stability and efficiency of the sedimentation operation, guaranteeing the quality of the red mud slurry sedimentation operation, and improving the practicality of the thickener.

[0019] Specifically, the feeding mechanism includes a collection cylinder 310, which is fixed to the bottom of the installation platform 120 by bolts. A feed pipe 320 is fixed to the outside of the collection cylinder 310, and a support base 321 is fixed to the outside of the feed pipe 320. The support base 321 is fixedly connected to the support plate 110. A guide plate 330 is fixed to the inner wall of the collection cylinder 310, and a connecting column 331 is fixed to the bottom of the guide plate 330. A distribution plate 340 is fixed to the bottom of the connecting column 331. With the feeding mechanism, the red mud slurry is injected into the collection cylinder 310 through the feed pipe 320. The guide plate 330 provides spiral support for the red mud slurry, and then the red mud slurry falls onto the distribution plate 340. The distribution plate 340 performs a distribution operation on the red mud slurry, which can evenly disperse the red mud slurry into the multi-cone sedimentation tank 100 in a parabolic manner.

[0020] Specifically, the filling mechanism includes an installation pipe 410, which is fixed to the top of the installation platform 120 by bolts. A collection trough 420 is fixed to the top of the installation pipe 410, and a feed nozzle 421 is fixed to the top of the collection trough 420. A connecting pipe 430 is fixed to the outside of the installation pipe 410, and a support ring 440 is fixed to the outside of the connecting pipe 430. The support ring 440 is rotatably connected to the drive shaft 230. By setting up the filling mechanism, flocculant is injected into the collection trough 420 through the feed nozzle 421 and enters multiple installation pipes 410 through the collection trough 420. This allows for multi-point flocculant addition during the feeding stage of the red mud slurry, facilitating the pre-mixing of the red mud slurry and flocculant.

[0021] Specifically, a conveying pipe 450 is fixed to the inner wall of the drive sleeve 240, and a spray arm 460 is fixed to the outer side of the drive sleeve 240 near the conveying pipe 450. By setting the spray arm 460, the flocculant is sprayed onto the red mud slurry in the multi-cone settling tank 100, realizing the two-stage addition of flocculant, ensuring the full mixing of flocculant and red mud slurry, and improving the settling speed of red mud slurry.

[0022] Specifically, a limiting slider 531 is fixed to the inner wall of the drive sleeve 530, and the limiting slider 531 is slidably connected to the drive sleeve 240; by setting the limiting slider 531 to limit and support the up and down movement of the drive sleeve 530, the stability of the scraping operation is ensured.

[0023] Specifically, the discharge mechanism includes a drive motor 610, which is fixed to the inner wall of the drive sleeve 240 by bolts. A drive rod 620 is provided at the output end of the drive motor 610, and multiple guide blades 630 are fixed on the outer side of the drive rod 620. A discharge pipe 640 is fixed at the bottom of the multi-cone sedimentation tank 100. By providing the discharge mechanism, the drive motor 610 drives the drive rod 620 to rotate, and the rotation of the drive rod 620 drives the guide blades 630 to rotate. The guide blades 630 agitate the sediment, and the sediment is discharged through the discharge pipe 640.

[0024] Working principle: During operation, the thickener is controlled by the main control unit 130. The red mud slurry is injected into the collection cylinder 310 through the feed pipe 320. The guide plate 330 provides spiral support for the red mud slurry, which then falls onto the distribution plate 340. The distribution plate 340 distributes the red mud slurry evenly, allowing it to fall parabolically into the multi-cone settling tank 100. The flocculant is injected into the collection trough 420 through the feed nozzle 421. The flocculant enters through the collection trough 420 into multiple installation pipes 410, enabling multi-point flocculant addition during the feeding stage of the red mud slurry. This facilitates pre-mixing of the red mud slurry and flocculant. The flocculant enters the drive shaft 230 through the connecting pipe 430 and the feed hole 231, then enters the spray arm 460 through the conveying pipe 450. Finally, the spray arm 460 sprays the flocculant onto the red mud slurry within the multi-cone settling tank 100, achieving two-stage flocculant addition and ensuring... Thorough mixing of flocculant and red mud slurry can improve the settling velocity of the red mud slurry. The drive shaft 230 rotates via a geared motor 220, which in turn rotates the drive sleeve 240, thereby rotating the scraping mechanism. The hydraulic rod 520 drives the drive sleeve 530 to move up and down, which in turn causes the scraper 550 to press against the bottom of the multi-cone settling tank 100. The scraper 550 scrapes the sediment and guides it to the discharge mechanism. The motor 610 drives the drive rod 620 to rotate, which in turn drives the guide blade 630 to rotate. The guide blade 630 agitates the sediment, which is then discharged through the discharge pipe 640. The multi-cone sedimentation tank 100 structure, with its large-cone deep cone at the bottom and multiple cones in the middle, increases the concentration of the bottom flow. The vertically moving scraper 550 prevents torque overload on the scraper frame 540 and the scraper 550, ensuring the stability of the sedimentation operation.
