Description
Technical Field
[0001] This utility model relates to the field of tungsten-molybdenum separation technology of waste catalysts, specifically a tungsten-molybdenum separation device for waste catalysts. Background Technology
[0002] In modern industrial processes, petroleum refining and metal extraction are of paramount importance, with catalysts playing a crucial role in the refining process. However, due to various factors, the activity and selectivity of catalysts gradually decline during use, eventually requiring their removal and disposal. These spent catalysts not only retain the value of the catalysts used in the production process but also typically contain toxic and harmful metal elements such as nickel and vanadium. Improper disposal of these spent catalysts can lead to serious environmental pollution, affecting the safety of water bodies, soil, and vegetation, and ultimately threatening ecosystems and human health.
[0003] Meanwhile, tungsten and molybdenum play an irreplaceable role in various high-end industrial applications, especially in cemented carbide, electronic equipment, and the defense industry. The scarcity of tungsten and molybdenum resources and their separation and extraction have always been technical challenges. This is because tungsten and molybdenum often exist in symbiotic forms in minerals, and their similar ionic radii and chemical properties make effective separation an extremely challenging task. With increasing demands for the quality of tungsten and molybdenum products and stricter control over impurity content, research into technologies for the efficient separation and recovery of tungsten and molybdenum has become particularly urgent.
[0004] Existing waste catalyst tungsten-molybdenum separation devices suffer from low separation efficiency. When tungsten and molybdenum coexist in severe conditions, their similar physicochemical properties and ionic radii result in poor selectivity during separation, hindering high-purity recovery and impacting their industrial application value. Many separation technologies involve complex chemical processes and equipment operation, leading to high equipment investment and maintenance costs. Furthermore, they face insufficient capacity and slow processing speeds when handling large-scale waste catalysts, failing to meet the demands of industrial-scale operations. No solutions have yet been proposed to address these technical problems. Utility Model Content

[0022] Please see Figure 1-2This utility model proposes a technical solution for a waste catalyst tungsten-molybdenum separation device: The waste catalyst tungsten-molybdenum separation device includes a base 1, specifically, the base 1 serves to support the entire structure. A bracket 2 is installed on one side of the base 1, and a cylinder 3 is installed on the bracket 2. The output end of the cylinder 3 is connected to a movable plate 4, which is movably connected to the bracket 2. Specifically, starting the cylinder 3 can drive the movable plate 4 connected to it to move up and down on the bracket 2. A support plate 5 is provided on one side of the movable plate 4, and a stirring mechanism is provided on the support plate 5. The stirring mechanism includes a drive motor 6, a rotating shaft 7, and several stirring plates 8 arranged on the rotating shaft 7. The drive motor 6 is fixedly installed on the top of the support plate 5. The rotating shaft 7 is located below the support plate 5. One end of the rotating shaft 7 passes through the support plate 5 and extends to the top of the support plate 5. The end of the rotating shaft 7 is fixedly connected to the output end of the drive motor 6. An extraction tank 9 is located at the top center of the base 1. Specifically, the support plate 5 serves to support the stirring mechanism. When the drive motor 6 is started, it drives the rotating shaft 7 connected to it to rotate, thereby causing the stirring plate 8 on the outer surface of the rotating shaft 7 to stir the solution in the extraction tank 9, so that the solution reacts with the extractant. Then the drive motor 6 is turned off, causing the solution in the extraction tank 9 to separate into layers. The bottom of the extraction tank 9 is arranged in a decreasing manner from top to bottom. The bottom of the extraction tank 9 is provided with a discharge port, and a valve is provided on the discharge port.
[0023] Please see Figure 1 As shown, a positioning plate 10 is further provided on one side of the support plate 5, and an arc-shaped opening 11 is provided on the movable plate 4. A screw is fixedly installed on the top of the positioning plate 10. One end of the top of the screw passes through the arc-shaped opening 11 and extends to the top of the arc-shaped opening 11, and a nut 12 is connected to the end of the screw.
[0024] In this embodiment, the positioning plate 10 connects the movable plate 4 and the support plate 5. The position of the support plate 5 can be adjusted by the screw and nut 12 to meet different usage requirements.
[0025] Please see Figure 1-2 As shown, the stirring mechanism further includes a baffle 13, which passes through the support plate 5 and is fixedly connected to the support plate 5.
[0026] In this embodiment, the stop lever 13 can limit the downward movement of the support plate 5.
[0027] Please see Figure 1-2 As shown, the bracket 2 is further provided with a guide rail 14, and a sliding block is provided on the guide rail 14. The sliding block is fixedly connected to the movable plate 4.
[0028] In this embodiment, the movable plate 4 moves along the guide rail 14, thereby improving the stability of the movable plate 4's movement.
[0029] Please see Figure 1-2 As shown, a controller 15 is further installed on the top of the bracket 2. The controller 15 is equipped with a display screen and several control buttons. An indicator light 16 is also provided below the control buttons.
[0030] In this embodiment, the controller 15 plays an overall control role to achieve automation, and the indicator light 16 serves as a reminder. The controller 15 integrates the control of the lifting of the cylinder 3 and the starting and stopping of the drive motor 6, realizing the automated operation of core processes such as stirring, settling and stratification, and draining. This effectively reduces manual intervention, making the operation not only simple but also greatly improving the efficiency and consistency of the separation process.
[0031] Please see Figure 1-2 As shown, casters 17 are further provided around the bottom of the base 1.
[0032] In this embodiment, the caster wheel 17 can move the base 1, improving convenience.
[0033] The working principle of this utility model:
[0034] The solution and extractant to be separated are placed inside the extraction tank 9. The cylinder 3 is started, which drives the movable plate 4 connected to it to move downward on the support 2, thereby moving the positioning plate 10 and the support plate 5, so that the stirring mechanism extends into the interior of the extraction tank 9. The drive motor 6 is started, which drives the rotating shaft 7 connected to it to rotate, so that the stirring plate 8 on the outer surface of the rotating shaft 7 stirs the solution in the extraction tank 9, so that the solution and the extractant react. Then the drive motor 6 is turned off, so that the solution in the extraction tank 9 will separate into layers, and then be discharged layer by layer through the outlet at the bottom of the extraction tank 9. The position of the support plate 5 can be adjusted by the screw and nut 12 to meet different usage requirements. The stop bar 13 can limit the downward movement of the support plate 5. When the movable plate 4 moves, it drives the sliding block to move on the guide rail 14, which improves the stability of the movement of the movable plate 4.
