Description

Technical Field

[0001] This utility model relates to the field of red mud treatment technology, specifically a red mud salt separation and collection device. Background Technology

[0002] Red mud is a highly alkaline solid waste discharged during the alumina industrial production process. It is characterized by large output, high alkalinity, and high salt content. Red mud contains a variety of soluble salts, which are both the core factor causing its environmental risks and a potential recycling resource.

[0003] Currently, the main method of disposing of red mud is stockpiling. During the stockpiling process, the soluble salts in the mud are easily leached by rainwater and migrate, seeping into the surrounding soil and groundwater, causing a series of serious ecological and environmental problems such as soil alkalization, compaction and groundwater pollution. At the same time, a large amount of valuable salt resources are abandoned along with the red mud, resulting in serious waste of resources. Utility Model Content

[0004] The purpose of this invention is to provide a red mud salt separation and collection device, which can separate the salt in red mud and reduce the environmental pollution caused by excessive salt content during the red mud storage period.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a red mud salt separation and collection device, comprising a processing tank, a discharge valve fixedly installed at the middle of the bottom of the processing tank, a discharge pipe fixedly installed at the bottom of the discharge valve, a fixed frame fixedly installed at the upper end of the outer surface of the processing tank, a first motor fixedly installed at the middle of the top of the fixed frame, a fixed box fixedly installed at the left end of the top of the fixed frame, a second motor fixedly installed at the right end of the top of the outer surface of the fixed box, a first gear fixedly installed at the output end of the second motor, a threaded sleeve movably connected between the left end of the top of the fixed box and the left end of the fixed frame via a bearing, a second gear fixedly installed at the middle of the threaded sleeve, the second gear meshing with the first gear, an adjusting screw threadedly connected to the inner cavity of the threaded sleeve, fixed plates fixedly installed on both sides of the adjusting screw, a riser fixedly installed between the surfaces of the two fixed plates, a rubber tube fixedly installed at the top of the riser, a conveying pump fixedly installed at the left end of the rubber tube, and a conveying pipe fixedly installed at the output end of the conveying pump.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] The components in this application, such as the processing box 1, support column 2, controller 3, protective plate 4, rubber hose 5, fixing frame 6, water inlet pipe 7, first motor 8, fixing box 9, delivery pump 10, delivery pipe 11, support frame 12, discharge valve 13, discharge pipe 14, stirring rod 15, stirring blade 16, spiral blade 17, adjusting screw 18, guide sleeve 19, riser 20, fixing plate 21, second gear 22, second motor 23, first gear 24, and threaded sleeve 25, are all general standard parts or parts known to those skilled in the art. Their structure and principle are common knowledge and can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0022] Example 1:

[0023] Please see Figures 1-4As shown, this utility model provides a red mud salt separation and collection device, including a processing tank 1. A discharge valve 13 is fixedly installed at the middle of the bottom of the processing tank 1, and a discharge pipe 14 is fixedly installed at the bottom of the discharge valve 13. A fixing frame 6 is fixedly installed at the upper end of the outer surface of the processing tank 1. A first motor 8 is fixedly installed at the middle of the top of the fixing frame 6. A fixing box 9 is fixedly installed at the left end of the top of the fixing frame 6. A second motor 23 is fixedly installed at the right end of the top of the outer surface of the fixing box 9. A first gear 24 is fixedly installed at the output end of the second motor 23. The top of the fixing box 9... A threaded sleeve 25 is movably connected to the left end of the fixed frame 6 via a bearing. A second gear 22 is fixedly installed at the middle end of the threaded sleeve 25. The second gear 22 meshes with the first gear 24. An adjusting screw 18 is threadedly connected to the inner cavity of the threaded sleeve 25. Fixed plates 21 are fixedly installed on both sides of the adjusting screw 18. A riser 20 is fixedly installed between the surfaces of the two fixed plates 21. A rubber tube 5 is fixedly installed at the top of the riser 20. A delivery pump 10 is fixedly installed at the left end of the rubber tube 5. A delivery pipe 11 is fixedly installed at the output end of the delivery pump 10.

[0024] In this technical solution, when it is necessary to separate the salt in the red mud, the second motor 23 is first started to drive the first gear 24 to rotate. The rotation of the first gear 24 drives the second gear 22 and the threaded sleeve 25 to rotate, and drives the adjusting screw 18 to move upward along the inner cavity of the threaded sleeve 25. The movement of the adjusting screw 18 drives the fixed plate 21 and the riser 20 to move until the adjusting screw 18 can be disengaged from the treatment tank 1. Then, red mud is added to the water inside the treatment tank 1, and under the action of continuous stirring, the salt in the red mud can be dissolved in the water. Then, an environmentally friendly flocculant is added to the solution, and under the action of stirring, the red mud particles in the solution can be flocculated and precipitated. Then, the second motor 23 is started to work in the opposite direction, driving the adjusting screw 18 and the fixed plate 21 to move upward. The riser 20 moves downwards, allowing it to be inserted into the water containing dissolved salt. With the operation of the pump 10, the water containing salt is extracted through the rubber hose 5 and the riser 20, and simultaneously transported to an external concentration tank via the delivery pipe 11 for salt evaporation and extraction. Meanwhile, as the water level inside the treatment tank 1 decreases, the control screw 18 and the rising pipe 20 adjust their movement height accordingly, ensuring that the end of the riser 20 is always immersed in the water. When the water level approaches the red mud sedimentation level, the movement of the riser 20 and the operation of the pump 10 are stopped. Then, by controlling the opening of the discharge valve 13, the sedimented red mud is discharged through the discharge pipe 14 to an external filter press for red mud filtration, thus completing the separation of red mud and salt.

[0025] It should be noted that, firstly, the water produced during the red mud filtration process by the external filter press can be refilled into the treatment tank 1 for further treatment and reuse; secondly, during operation, the adjusting screw 18 does not need to be inserted into the water, and personnel can regularly maintain the surface of the adjusting screw 18.

[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 3 As shown, a stirring rod 15 is fixedly installed at the output end of the first motor 8. The upper end of the stirring rod 15 is movably connected to the middle end of the fixed frame 6 through a bearing. A stirring blade 16 is fixedly installed at the middle end of the stirring rod 15, and a spiral blade 17 is fixedly installed at the lower end of the stirring rod 15. There are two spiral blades 17.

[0028] In this technical solution, the operation of the first motor 8 can drive the stirring rod 15, stirring blade 16 and spiral blade 17 to rotate, which can quickly stir the water and red mud inside the treatment tank 1, improve the rate of salt dissolution in the red mud, and during the subsequent addition of environmentally friendly flocculant, can quickly stir and mix the environmentally friendly flocculant with the water, thereby improving the flocculation effect of red mud in the water.

[0029] Example 3:

[0030] Based on Embodiment 1, this utility model is as follows: Figures 1-3 As shown, a guide sleeve 19 is fixedly installed on the front surface of the fixed box 9. The upper end of the riser 20 is slidably connected to the inner cavity of the guide sleeve 19. Support columns 2 are fixedly connected to the bottom of the outer surface of the treatment box 1. A base plate is fixedly connected between the bottom of two support columns 2. A water inlet pipe 7 is fixedly installed on the upper end of the back of the treatment box 1. A support frame 12 is fixedly installed between the right side of the delivery pump 10 and the left side of the fixed frame 6. A controller 3 is fixedly installed in the middle of the front surface of the treatment box 1. The controller 3 is electrically connected to the first motor 8 and the second motor 23 respectively. A protective plate 4 is fixedly installed in the middle of the front surface of the treatment box 1 and above the controller 3.

[0031] In this technical solution, the guide sleeve 19 is used to guide the riser 20 and prevent it from tilting or rotating during movement. The support column 2 and the base plate are used to support the bottom of the processing box 1. The support frame 12 is used to support and fix the delivery pump 10. The controller 3 is used to facilitate personnel to control the first motor 8 and the second motor 23.
