[0002] Alumina is an important industrial raw material with a wide range of applications in industry. The waste generated during alumina production is red mud, and China, as a major alumina producer, discharges a significant amount of red mud annually.

[0003] However, red mud contains a lot of water. If the red mud is directly discharged as waste, the water resources in the red mud will not be effectively utilized, which will result in the waste of water resources. Therefore, there is an urgent need to provide a red mud vortex water resource recovery device. Utility Model Content

[0004] To address the problems mentioned above, this invention provides a red mud hydrocyclone water resource recovery and utilization device. A first pump transports red mud from a red mud pool to the hydrocyclone body via a feed pipe. After hydrocyclone swirl, water and some impurities are discharged through a top overflow pipe. The swirled red mud then falls into a collection tank through a bottom flow pipe for collection. Water and some impurities in the overflow pipe flow into a first collection tank. Impurities settle in the first collection tank and then fall to the bottom. The clear water at the top of the first collection tank overflows through a drain hole and drain pipe to a second collection tank for recovery and collection. The clear water in the second collection tank can be reused for industrial use in the workshop, reducing water waste and effectively utilizing the water resources recovered from the red mud.

[0025] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The present invention will be described in detail with specific embodiments.

[0026] like Figures 1 to 5 As shown, the present invention provides a red mud cyclone post-water resource recovery device, including a red mud pool 1, into which tailings red mud are discharged. A hydrocyclone body 2 is provided next to the red mud pool 1, and an overflow pipe 21 is fixedly connected to the overflow port at the top of the hydrocyclone body 2.

[0027] The feed inlet of the hydrocyclone body 2 is fixedly connected to a feed pipe 22, and a first pump body 3 is fixedly connected to the feed pipe 22. A first support base 31 is fixedly connected to the bottom of the first pump body 3, and the first support base 31 supports the first pump body 3. The end of the feed pipe 22 away from the hydrocyclone body 2 is placed in the red mud pool 1, and the first pump body 3 transports the red mud in the red mud pool 1 into the hydrocyclone body 2 through the feed pipe 22.

[0028] The bottom outlet of the hydrocyclone body 2 is fixedly connected to the bottom flow pipe 23, and a collection tank 4 is provided below the end of the bottom flow pipe 23 away from the hydrocyclone body 2. After the red mud inside the hydrocyclone body 2 is swirled, water and some impurities are discharged through the top overflow pipe 21, and the red mud after swirling falls into the collection tank 4 through the bottom flow pipe 23 for collection.

[0029] A first water collection tank 5 is provided below the end of the overflow pipe 21 away from the hydrocyclone body 2. Water and some impurities in the overflow pipe 21 flow into the first water collection tank 5. The impurities settle in the first water collection tank 5 and fall to the bottom. The top of the first water collection tank 5 is clean water that meets the workshop's reuse requirements after settling.

[0030] A circular drain hole 51 is provided on the upper part of the side wall of the first water collection tank 5, and the drain hole 51 is connected to the interior of the first water collection tank 5. A drain pipe 52 is fixedly connected to the outer wall of the first water collection tank 5, and the drain pipe 52 is connected to the drain hole 51. A second water collection tank 6 is located below the end of the drain pipe 52 away from the first water collection tank 5. The clean water at the top of the first water collection tank 5 overflows into the second water collection tank 6 through the drain hole 51 and the drain pipe 52 for recycling and collection. The clean water in the second water collection tank 6 can be reused for industrial water use in the workshop, reducing water waste and effectively utilizing the water resources in the red mud.

[0031] A water outlet pipe 7 is inserted into the second water collection tank 6, and a second pump body 71 is fixedly connected to the water outlet pipe 7. A second support base 711 is fixedly connected to the bottom of the second pump body 71, and the second support base 711 supports the second pump body 71.

[0032] A filter screen plate 53 is connected to the inner wall of the first water collection tank 5 on the side with the drain hole 51. A fixing component 8 is provided between the filter screen plate 53 and the inner wall of the first water collection tank 5, and the fixing component 8 connects and fixes the filter screen plate 53 to the inner wall of the first water collection tank 5. Water in the first water collection tank 5 enters the drain hole 51 after passing through the filter screen plate 53. The filter screen plate 53 reduces the possibility of impurities in the first water collection tank 5 being discharged through the drain hole 51.

[0033] The fixing assembly 8 includes a pair of first support rods 81 fixedly connected to the inner wall of the first water collection tank 5. The first support rods 81 are disposed on the inner wall of the first water collection tank 5 on the side where the drain hole 51 is located. A vertically arranged second support rod 82 is fixedly connected to the end of each first support rod 81, causing the lower surface of the filter screen plate 53 to abut against the upper surface of the first support rod 81. A first magnet 83 is fixedly connected to the side of the filter screen plate 53 away from the second support rod 82, and the first magnet 83 is arranged around the side wall of the filter screen plate 53. A second magnet 84 is fixedly connected to the inner wall of the first water collection tank 5 on the side where the drain hole 51 is located, and the second magnet 84 is arranged around the inner wall of the first water collection tank 5. When the filter screen plate 53 abuts against the upper surface of the first support rod 81, the first magnet 83 and the second magnet 84 attract and abut against each other, thus connecting and fixing the filter screen plate 53 to the first water collection tank 5.

[0034] Each second support rod 82 is fixedly connected to three springs 811 on the side near the filter screen plate 53. A pressure plate 812 is provided between each second support rod 82 and the filter screen plate 53. The end of the spring 811 away from the second support rod 82 is fixedly connected to the pressure plate 812. The side of the pressure plate 812 near the filter screen plate 53 abuts against the filter screen plate 53. When the first magnet 83 and the second magnet 84 abut against each other, the springs 811 are compressed, and the pressure plate 812 presses the filter screen plate 53 away from the second support rod 82, increasing the stability of the attraction and abutment between the first magnet 83 and the second magnet 84.

[0035] When the filter screen 53 needs cleaning, move the pressure plate 812 away from the filter screen 53, separating the pressure plate 812 from the filter screen 53 and separating the first magnet 83 and the second magnet 84, allowing the filter screen 53 to be removed for cleaning. After cleaning, bring the filter screen 53 into contact with the upper surface of the first support rod 81, attracting the first magnet 83 and the second magnet 84, and bringing the pressure plate 812 into contact with the filter screen 53.

The conveyor belt 9 transports the red mud leaving the discharge port 411.

[0037] The bottom inner wall of the receiving pool 4 is provided with a slope 42. The slope 42 facilitates the movement of the red mud in the receiving pool 4 towards the side closer to the discharge port 411, making it easier for the red mud in the receiving pool 4 to leave the discharge port 411.

[0038] The implementation principle of the red mud hydrocyclone water resource recovery device provided by this utility model is as follows: The first pump body 3 transports the red mud in the red mud pool 1 to the hydrocyclone body 2 through the feed pipe 22. After the red mud inside the hydrocyclone body 2 is swirled, water and some impurities are discharged through the top overflow pipe 21. The red mud after swirling falls into the collection pool 4 through the bottom flow pipe 23 for collection. The water and some impurities in the overflow pipe 21 flow into the first water collection pool 5. After the impurities settle in the first water collection pool 5, they fall to the bottom. The clear water at the top of the first water collection pool 5 overflows to the second water collection pool 6 for recovery and collection through the drain hole 51 and the drain pipe 52. When the second pump body 71 is working, the second pump body 71 discharges the clear water in the second water collection pool 6 through the water outlet pipe 7 for utilization.
