Description

Technical Field

[0001] This utility model relates to the field of vanadium precipitation wastewater treatment technology, specifically a vanadium extraction device for vanadium precipitation wastewater recovery. Background Technology

[0002] Vanadium precipitation wastewater is industrial wastewater generated during the vanadium ore smelting and vanadium product production (such as ferrovanadium alloy, vanadium pentoxide, etc.) after the vanadium element is separated through the "vanadium precipitation" process. Since vanadium precipitation wastewater contains a certain amount of vanadium resources (usually in the form of vanadate ions, vanadium hydroxide flocs, etc.), the wastewater can be further avoided by treating it with a vanadium extraction device.

[0003] A utility model patent with the existing authorization publication number CN214990813U discloses a vanadium extraction device for recovering vanadium-precipitated wastewater, relating to the technical field of the chemical industry. This utility model includes a container, a rotating motor, a transfer box, and a filter cylinder. A top cover is fixed to the top of the container, a connecting seat is fixed to the center of the top of the top cover, and a rotating motor is fixed to the top of the connecting seat. A transfer box is located on one side of the container, with flocculants confined in the middle of the transfer box. A filter cylinder is located on the side of the transfer box away from the container. This invention solves the problems of high energy consumption and inability to reuse water in existing vanadium extraction devices for vanadium-precipitated wastewater recovery by setting up a container, rotating motor, transfer box, and filter cartridge. It enables the rapid and low-energy extraction of vanadium from vanadium-precipitated wastewater and the purification of the wastewater. However, in the operation of this vanadium extraction device, the container is equipped with a single stirring blade to mix the wastewater and reducing agent, which results in poor mixing effect. Furthermore, after the wastewater is flocculated by flocculants, it is filtered through a filter cartridge. Since the filter cartridge is planar, the entire surface of the cartridge is deposited with vanadium ions, causing blockage and requiring frequent cleaning. Therefore, we propose a vanadium extraction device for vanadium-precipitated wastewater recovery to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, an embodiment of the present invention discloses a vanadium extraction device for vanadium-containing wastewater recovery, comprising a base 1 and a tank 2. A frame 14 is fixed at an opening on the front of the tank 2, and a transparent plate 15 is fixed inside the frame 14, facilitating the observation of the mixing of the wastewater inside the tank 2 from the outside. The tank 2 is fixed to the top of the base 1 by two supports. A stirring mechanism 3 is provided inside the tank 2. The stirring mechanism 3 includes a drive shaft 301 rotatably connected to the top of the tank 2 via bearings. The bottom end of the drive shaft 301 extends into the interior of the tank 2 and is fixed with a rotating seat 302. An annular rail 12 is fixed to the inner wall of the top of the tank 2. An annular block 13 adapted to the annular rail 12 is fixed to the top of the rotating seat 302, which can adjust the rotation of the rotating seat 302. 02 serves as an auxiliary support to ensure greater stability during rotation. Four drive shafts 303 and four drive shafts 304 are rotatably connected to the rotating base 302 via bearings. Two gears 305 are fixed to the surface of each drive shaft 303, and gears 306 are fixed to the surface of each drive shaft 304. A gear ring 307 is fixed to the inner wall of the top of the tank 2. Four gears 305 mesh with the gear ring 307, and the other four gears 305 mesh with their corresponding gears 306. A connecting block 308 is fixed to the bottom of each drive shaft 304, and a mixing blade 309 is fixed to the bottom of each connecting block 308. A wastewater inlet pipe 4, an addition pipe 5, and a discharge pipe 6 are connected and fixed to the tank 2. The discharge pipe 6... A valve is installed, and a guide shell 7 is set above the base 1. A conical filter 8 is snapped onto the top of the guide shell 7. During the process of using this vanadium extraction device for vanadium wastewater recovery, the wastewater inlet pipe 4 can be connected and fixed to the vanadium wastewater conveying pipe. When the vanadium wastewater inside the tank 2 reaches a certain height, an appropriate amount of reducing agent can be sent into the tank 2 through the addition pipe 5. Since the output end of the drive motor at the top of the tank 2 is fixedly connected to the top of the drive shaft 301, the drive motor can be started to drive the drive shaft 301 to rotate. After the drive shaft 301 rotates, it will drive the rotating seat 302 to rotate. At this time, with the cooperation of the gear ring 307 and the four gears 305 above, when the rotating seat 302 rotates, it can drive the four transmission shafts 303 to rotate. After shaft 303 rotates, the four gears 305 and 306 below work together to drive shaft 304 to rotate. The rotation of shaft 303 drives connecting block 308 to rotate, and the rotation of connecting block 308 drives mixing blades 309 to stir and mix the vanadium-laden wastewater and reducing agent inside tank 2. Since the four mixing blades 309 rotate around shaft 304 and also around drive shaft 301, the mixing and dispersion speed of the vanadium-laden wastewater and reducing agent inside tank 2 is increased. After the vanadium-laden wastewater and reducing agent are mixed, an appropriate amount of flocculant can be added to the inside of tank 2 through adding pipe 5.Next, the above operation is repeated to mix the vanadium-precipitated wastewater and flocculant. After mixing, the valve on the discharge pipe 6 is opened to discharge the treated vanadium-precipitated wastewater into the tank 2. The discharged wastewater then enters the conical filter hopper 8, where the flocculated vanadium ions remain. The filtered water then enters the guide shell 7 and is discharged through the drain pipe. Since the conical filter hopper 8 is engaged with the guide shell 7, it can be easily removed.

[0026] like Figure 3 As shown, in some embodiments, a drive shaft 310 is fixed to the bottom of the rotating seat 302, a spiral blade 311 is fixed to the surface of the drive shaft 310, and a conical block 312 is fixed to the bottom end of the drive shaft 310. The surface of the conical block 312 is fixed with scrapers 313 adapted to the tank body 2 in a ring array. When the rotating seat 302 rotates, it can drive the drive shaft 310 to rotate. When the drive shaft 310 rotates, it can drive the spiral blade 311 to rotate, thereby achieving auxiliary mixing treatment of the vanadium-precipitated wastewater inside the tank body 2. Secondly, when the drive shaft 310 rotates, it can also drive the conical block 312 to rotate. After the conical block 312 rotates, it will drive the four scrapers 313 to rotate, thereby avoiding the occurrence of uneven mixing of the vanadium-precipitated wastewater located at the bottom of the tank body 2.

[0027] like Figure 1 As shown, in some embodiments, four damping buffers 9 are fixed to the top of the base 1, and a vibration table 10 is fixed to the top of the four damping buffers 9. The guide shell 7 is fixed to the top of the vibration table 10, and a vibration motor 11 is fixed to the bottom of the vibration table 10. In use, the vibration table 10 can be driven to vibrate by driving the vibration motor 11, which in turn drives the guide shell 7 to vibrate. Therefore, the solid-liquid separation speed inside the conical filter 8 can be accelerated. The damping buffers 9 can prevent the vibration from being transmitted to the base 1. Furthermore, the vibration direction of the vibration motor 11 is up and down. The inertial force generated by the vibration can assist in the flocculation and precipitation of vanadium ions to settle to the bottom of the conical funnel.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
