[0002] With the continuous development of bauxite mining and flotation technology, the treatment of bauxite flotation tailings wastewater has become an important environmental issue. Bauxite flotation tailings wastewater contains a large amount of solid particles, chemicals and other harmful substances. If it is not effectively treated, it will cause serious pollution to the environment.

[0003] In the existing technology, bauxite flotation tailings wastewater is usually treated by methods such as sedimentation, filtration, and chemical treatment. The bauxite flotation tailings wastewater treatment device usually includes a simple sedimentation tank, an ordinary filtration device, and a conventional dosing equipment. Usually, gravity is used to naturally precipitate larger particles, and then some fine particles are removed through the interception effect of the filter medium. Finally, chemical agents are added to react to remove harmful substances.

[0004] However, conventional bauxite flotation tailings wastewater treatment systems present several challenges. One major issue is the difficulty in effectively separating larger particles from the wastewater. Existing systems often fail to effectively separate larger particles, which can easily lead to blockages and interference in subsequent treatment processes, impacting the efficiency and stability of wastewater treatment. To address this issue, a bauxite flotation tailings wastewater purification system was proposed. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 2 The utility model provides an embodiment of a bauxite flotation tailings wastewater purification device, including a base 1, a bearing assembly is provided at the bottom of the base 1, and the bearing assembly is used to support the device. The upper surface of the base 1 is fixedly connected to a sedimentation box 3, and both sides of the sedimentation box 3 are symmetrically provided with a first motor 4 and a column 7.

The side wall of the connecting plate 11 is fixedly connected to a filter plate 12. The filter plate 12 is slidably connected to the inner wall of the sedimentation box 3. The bearing assembly includes a support leg 2, the top of the support leg 2 is fixedly connected to the lower surface of the base 1, the side wall of the sedimentation box 3 is fixedly connected to a water pump 13, the output end of the water pump 13 is fixedly connected to a water pipe 14, one end of the water pipe 14 is fixedly connected to a filter tank 15, the side wall of the filter tank 15 is fixedly connected to a support frame 16, and the side wall of the filter tank 15 is fixedly connected to a water pipe 2 17;

[0032] Specifically, when using the device, first inject wastewater into the sedimentation tank 3, and the wastewater is in a relatively static state in the sedimentation tank 3. After standing for a period of time, the relatively large particles in the wastewater gradually sink due to their own gravity and are finally settled on the filter plate 12. At this time, the first motor 4 starts to run, driving the sprocket 5 to rotate. The rotation of the sprocket 5 prompts the chain 6 to move. The movable block 10 is fixed on the chain 6. Therefore, during the movement of the chain 6, the movable block 10 is also driven to slide upward on the limit column 9. The movable block 10 is connected to the filter plate 12 through the connecting plate 11. Therefore, the upward sliding of the movable block 10 further drives the displacement of the connecting plate 11 and the filter plate 12, which makes The larger particles deposited on the filter plate 12 can be quickly separated out, and the staff can quickly recycle the bauxite particles and other particles filtered out on the filter plate 12, thereby improving resource utilization. After successfully separating the larger particles in the wastewater, the wastewater enters the filter tank 15 through the water pipe 14 under the extraction action of the water pump 13. The filter tank 15 further filters the wastewater to remove some of the smaller impurities. The filter tank 15 uses multiple layers of different filter media, including coarse filter screens, activated carbon filter layers, fine fiber filter membranes and other media. Afterwards, the wastewater treated by the filter tank 15 slowly flows into the mixing barrel 18 through the water pipe 2 17, preparing for subsequent processing steps.

[0033] Reference Figure 3 The upper surface of the base 1 is fixedly connected to a bracket 26, the top of the bracket 26 is fixedly connected to a mixing barrel 18, the side wall of the mixing barrel 18 is fixedly connected to a water outlet valve 25, the upper surface of the base 1 is fixedly connected to a bracket 1 24, the top of the bracket 1 24 is fixedly connected to a second motor 19, the output end of the second motor 19 is fixedly connected to a connecting arm 20, the side wall of the bracket 1 24 is fixedly connected to a fixed gear 21, the side wall of the connecting arm 20 is fixedly connected to an agitator 23, the top of the agitator 23 is fixedly connected to a movable gear 22, the movable gear 22 is meshed with the fixed gear 21, and the agitator 23 is rotatably connected to the inside of the bracket 1 24;

[0034] Specifically, wastewater flows into the mixing barrel 18 through the water pipe 2 17. At this time, the second motor 19 starts to run, driving the connecting arm 20 to rotate synchronously. With the cooperation of the top fixed gear 21 and the movable gear 22 on the top of the stirring rod, the connecting arm 20 drives the agitator 23 to rotate in the circular ring set in the middle section of the bracket 1 24. During the rotation process, the blades of the agitator 23 continuously stir the wastewater and chemicals in the mixing barrel 18 so that the two can fully contact and mix. In this way, the effect of full reaction of wastewater and chemicals in the mixing barrel 18 is achieved. Then, when the reaction is gradually completed, the staff can discharge the neutralized wastewater through the water outlet valve 25 at the bottom of the mixing barrel 18.

[0035] Working principle: When using the device, first inject wastewater into the sedimentation tank 3. After standing for a period of time, the larger particles in the wastewater will settle on the filter plate 12. At this time, the first motor 4 rotates to drive the sprocket 5 to rotate. The rotation of the sprocket 5 prompts the movement of the chain 6 and drives the movable block 10 to slide on the limit column 9. The movable block 10 drives the displacement of the connecting plate 11 and the filter plate 12, thereby achieving the effect of quickly separating larger particles in the wastewater. After separating the larger particles in the wastewater, the wastewater enters the filter tank 15 through the water pump 13 and the water pipe 14, and then flows into the mixing barrel 18 through the water pipe 2 17. At this time, the second motor 19 rotates to drive the connecting arm 20 to rotate, and the connecting arm 20 drives the agitator 23 to rotate inside the bracket 1 24, thereby achieving the effect of full reaction of the wastewater and the chemical agent in the mixing barrel 18.
