Description

Technical Field

[0001] The invention relates to the technical field of rubidium-containing tailings recovery, in particular to a filtering device and a process for efficiently recovering rubidium from low-grade rubidium-containing tailings. Background Art

[0002] Rubidium is a silvery-white waxy soft metal. Its chemical properties are more active than potassium. It easily releases electrons under the action of light and reacts violently with water to generate hydrogen and rubidium hydroxide. It easily reacts with oxygen to generate complex oxides. When recovering rubidium ore from low-grade rubidium-containing tailings, it is necessary to use a filtering device to filter the rubidium compounds precipitated by the ammonium phosphomolybdate precipitation method to achieve the purpose of recovering the rubidium ore.

[0003] When the ammonium phosphomolybdate precipitation method is used to react and precipitate the rubidium ore in the low-grade rubidium-containing tailings, a phosphoric acid solution of ammonium phosphomolybdate is added to the filtering device to react with the rubidium ore in the rubidium-containing tailings to generate a rubidium salt precipitate and phosphomolybdate blue. Accelerating the reaction speed of the ammonium phosphomolybdate precipitation reaction is the key to improving the efficiency of recovering the rubidium ore. In the process of recovering the rubidium ore, the existing filtering device only accelerates the ammonium phosphomolybdate precipitation reaction by stirring the reaction solution with a stirring rod. The stirring range of the stirring rod is relatively limited. Since the solution in the filtering device is not stirred evenly enough, the ammonium phosphomolybdate concentration of the reaction solution near the rubidium ore in the rubidium-containing tailings will be reduced, thereby reducing the reaction speed of the ammonium phosphomolybdate precipitation reaction in the filtering device, resulting in a reduction in the recovery efficiency of rubidium.

[0004] In view of the above problems, it is found that it is difficult to avoid the above problems at the same time when using the existing filtering devices for recovering rubidium on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, thus failing to achieve the desired effect.

[0019] A filtering process for efficiently recovering rubidium from low-grade rubidium-containing tailings by a filtering device comprises the following steps:

When the top cover is installed, the driving shaft fixed at the output end of the switched reluctance motor will extend into the rotating groove opened on the filter screen, so that the power output by the switched reluctance motor can be used to drive the stirring mechanism to stir the reaction substances in the filter cartridge;

[0021] S2: Then, the controller controls the operation of the switched reluctance motor to make the driving shaft rotate forward and reverse, so that the rotating rod stirs the solution in the filter cartridge. The first gear meshes with the second gear, so that the rotating rod can rotate in the rotating hole, thereby rotating the spiral blades, causing the reaction solution in the filter cartridge to roll and stir, and at the same time, the four fixed scrapers fixed on the outer surface of the driving shaft are driven to move horizontally, so as to facilitate the rotation of the rubidium-containing tailings solids on the filter screen.

At the same time, the first heating device, the second heating device and the third heating device are controlled by the PLC controller to heat the solution in the filter device, thereby accelerating the reaction rate of the rubidium tailings on the filter net with the ammonium phosphomolybdate phosphoric acid solution. After the reaction is completed, the solenoid valve and the switch valve are opened, the drain pipe discharges the reacted solution in the filter cartridge, and the clamping ring is manually pulled to remove the filter net with the reacted precipitate from the filter cartridge to complete the recovery of rubidium.

[0023] The beneficial effects of the present invention are:

[0024] The present invention provides a tumbling stirring unit to tumble and stir the reaction solution in the filter device, so that the reaction solution quickly tumbles up and down in the filter device, so that the reaction solution is fully in contact with the rubidium-containing tailings, thereby improving the recovery efficiency of rubidium.

[0025] The present invention provides a scraping and stirring unit to scrape and stir the solid rubidium-containing tailings on the filter screen, and then uses a sliding scraper to scrape the solid rubidium-containing tailings on the filter screen, so as to further allow the reaction solution to fully contact with the rubidium-containing tailings, thereby improving the reaction rate of the rubidium-containing tailings and the reaction solution.

[0053] The working principle of the above scheme is: when the rubidium tailings react with the ammonium phosphomolybdate phosphoric acid solution on the filter screen 2205, the PLC controller is controlled, and the PLC controller controls the first heating device 307, the second heating device 308 and the third heating device 309 to heat the solution in the filter device, and starts the ultrasonic generator to make the ultrasonic transducer 303 ultrasonically vibrate the reaction material in the filter cartridge 11.

[0054] A filtering process for efficiently recovering rubidium from low-grade rubidium-containing tailings by a filtering device comprises the following steps:

[0055] S1: First, slide the filter 2205 into the filter cartridge 11, so that the rubidium-containing tailings react with the ammonium phosphomolybdate phosphoric acid solution on the filter 2205. When the top cover 2101 is installed, the drive shaft 2113 fixed at the output end of the switch reluctance motor 2103 extends into the rotating groove 2206 provided on the filter 2205, so that the power output by the switch reluctance motor 2103 is conveniently used to drive the stirring mechanism 2 to stir the reaction substances in the filter cartridge 11;

[0056] S2: Then the controller controls the switched reluctance motor 2103 to run, so that the driving shaft 2113 rotates forward and reversely, so that the rotating rod 2110 stirs the solution in the filter cartridge 11, and the first gear 2108 is meshed with the second gear 2109, so that the rotating rod 2110 rotates in the rotating hole 2106, so that the spiral blades 2112 rotate, so that the reaction solution in the filter cartridge 11 rolls and stirs, and at the same time, the four fixed scrapers 2217 fixed on the outer surface of the rotating shaft 2113 are driven to move horizontally, so as to facilitate the The rubidium tailings solid on the filter screen 2205 rotates, and the rotation of the driving shaft 2113 drives the reel 2212 to reel in the four reeling ropes 2214, thereby pulling the sliding block 2215 to slide in the cross slide 2218 and approach the driving shaft 2113, and the sliding scraper 2216 can be used to scrape the rubidium tailings solid on the filter screen 2205 horizontally, and the driving shaft 2113 is reversed, and the sliding scraper 2216 scrapes in the opposite direction, thereby increasing the reaction rate of the rubidium tailings and the reaction solution;

[0057] S3: While stirring the solution in the filter cartridge 11, multiple ultrasonic transducers 303 are installed from the fixed threaded holes 301 into the fixed sleeve 302, and the ultrasonic transducers 303 are placed in the reaction solution in the filter cartridge 11. The connecting wires 306 on the multiple ultrasonic transducers 303 are connected to the ultrasonic generator. By controlling the ultrasonic generator, the ultrasonic transducers 303 perform ultrasonic vibration on the reaction substances in the filter cartridge 11. At the same time, the first heating device 307, the second heating device 308 and the third heating device 309 are controlled by the PLC controller to heat the solution in the filter device, thereby accelerating the reaction rate of the rubidium tailings on the filter screen 2205 with the ammonium phosphomolybdate phosphoric acid solution. After the reaction is completed, the solenoid valve 15 and the switch valve 17 are opened, and the drain pipe 16 discharges the reacted solution in the filter cartridge 11. The clamping ring 2201 is manually pulled to remove the filter screen 2205 from the filter cartridge 11 with the reacted precipitate, thereby completing the recovery of rubidium.
