Description

Technical Field

[0001] This invention relates to the field of metallurgical technology, and in particular to an apparatus for extracting rubidium and cesium salts from lepidolite. Background Technology

[0002] Lepidolite, also known as lepidolite, is one of the main raw materials for extracting the rare metal lithium. Lepidolite often contains rubidium and cesium, which are also important raw materials for extracting these rare metals. The content of rubidium and cesium in lepidolite raw materials is generally around 0.2-1.5%.

[0003] In the existing technology, the process of extracting rare metal elements from lepidolite mainly involves: mixing lepidolite powder with dilute sulfuric acid solution to form a solid-liquid mixture; heating the solid-liquid mixture to above 70°C, filtering and removing slag, and obtaining filtrate after lithium extraction; and repeatedly cooling, crystallizing, heating, and filtering the filtrate to gradually extract rubidium and cesium salts.

[0004] Currently, the extraction of rare metal elements from lepidolite involves different extraction devices due to varying operational steps. This necessitates frequent device changes by staff, resulting in cumbersome procedures, complex extraction processes, and the loss of some rare metal elements due to frequent device changes. Furthermore, the incomplete reaction between lepidolite powder and dilute sulfuric acid solution fails to fully displace the rare metal elements, leading to a significant waste of these rare resources.

[0008] Furthermore, the filtration mechanism includes a cylindrical cylinder, a vertical spring, a support rod, a large magnetic ring, a filter screen, a small magnetic ring, a vibration spring, and a limiting ring. The cylindrical cylinder is fixedly connected to the bottom of the extraction cylinder, and the support rod is slidably connected to the extraction cylinder.

The large magnetic ring and the small magnetic ring have opposite magnetic properties. The filter screen is fixedly connected to the outside of the large magnetic ring and is slidably connected to the inner wall of the extraction cylinder. A vibration spring connects the large magnetic ring to the bottom of the inner wall of the extraction cylinder. The limiting ring is fixedly connected to the lower part of the inner wall of the extraction cylinder, and the filter screen is located above the limiting ring.

[0009] Furthermore, the impurity scraping mechanism includes a scraper, a horizontal spring, a winding wheel, and a steel wire rope. Two scrapers are slidably connected to the inner wall of the extraction cylinder.

[0010] Furthermore, the reflux mechanism includes a water pump, a suction pipe, a three-way connecting pipe, a three-way valve core, a reflux pipe, and a discharge pipe. The water pump is fixedly connected to the outer wall of the middle part of the extraction cylinder.

[0012] Furthermore, it also includes a liquid outlet ring and liquid outlet nozzles. The liquid outlet ring is fixedly connected to the upper part of the inner wall of the extraction cylinder. The liquid outlet ring is connected to the other end of the reflux pipe. Several liquid outlet nozzles are connected to the inner wall of the liquid outlet ring.

[0013] The beneficial effects are: 1. The present invention drives the screw rod to rotate via a motor, which in turn drives the hexagonal rod to rotate, causing the stirring rod to rotate and agitate the solid-liquid mixture of lithium mica ore powder and dilute sulfuric acid solution on the high-temperature rubber stopper. This prevents the lithium mica ore powder from settling, thereby allowing the lithium mica ore powder and dilute sulfuric acid solution to mix fully and react rapidly to extract metallic elements such as rubidium, cesium and lithium from the lithium mica ore powder.

[0014] 2. This invention uses a hexagonal rod that rotates and moves downwards to compress a high-temperature rubber stopper, causing the reacted solid-liquid mixture to flow through the high-temperature rubber stopper onto a filter screen. The filter screen filters out solid impurities in the solid-liquid mixture, thereby separating the solid and liquid components to obtain a mixed liquid. At the same time, two scrapers move away from each other, scraping the solid impurities on the filter screen and removing them, thus reducing unnecessary operations for workers and making it easier for them to remove impurities.

[0015] 3. This invention uses a water pump to re-extract the mixed liquid from the bottom of the extraction cylinder onto a high-temperature rubber stopper, where it is then mixed and heated again with the scraped solid impurities. This process involves multiple heating and filtration of the solid-liquid mixture, forming an integrated operation that reduces equipment replacement and operation. This simplifies the extraction process of rubidium and cesium salts, improves overall extraction efficiency, and simultaneously refines the rubidium, cesium, and lithium metal elements in the solid impurities multiple times, reducing the waste of these elements.

[0037] The impurity scraping mechanism includes a scraper 91, a horizontal spring 92, a winding wheel 93, and a steel wire rope 94. Two scrapers 91 are slidably connected to the inner wall of the extraction cylinder 2. The two scrapers 91 are symmetrically arranged and both are located above the filter screen 85 and in contact with the filter screen 85. Two horizontal springs 92 are fixedly connected to each plate cover 3, and the other end of each horizontal spring 92 is in contact with the scraper 91.

[0040] Initially, the conical plug on the support rod 83 blocked the high-temperature rubber plug 52, keeping the high-temperature rubber plug 52 sealed. Because the steel wire rope 94 was held in place by the support rod 83, the horizontal spring 92 was compressed. In actual operation, the operator first opened the top cover 5 and added the solid-liquid mixture of lepidolite powder and dilute sulfuric acid solution into the extraction cylinder 2. Then, the top cover 5 was reattached to the extraction cylinder 2 to seal it. Several heating wires 51 heated the solid-liquid mixture inside the extraction cylinder 2, raising the reaction temperature to approximately 70 degrees Celsius, causing a chemical reaction between the lepidolite powder and the dilute sulfuric acid solution. Then, the operator started the motor 71. The output shaft of the motor 71 rotated, driving the hexagonal cylinder 72, the threaded rod 73, and the hexagonal... The hexagonal rod 74 rotates together with the stirring rod 76, causing the stirring plate 75 and stirring rod 76 to rotate together. The rotation of stirring rod 76 agitates the solid-liquid mixture on the high-temperature rubber stopper 52, preventing the lepidolite powder from settling. This allows the lepidolite powder to mix thoroughly with the dilute sulfuric acid solution, resulting in a rapid chemical reaction. Consequently, within the same reaction time, the efficiency of extracting metal elements such as rubidium, cesium, and lithium can be improved. Since the threaded rod 73 is connected to the upper cover 5 by threads, and the upper cover 5 is fixed, the threaded rod 73 moves downward as it rotates, causing the hexagonal rod 74 to move downward as well. The downward movement of the hexagonal rod 74 brings it into contact with the conical stopper on the support rod 83, pushing the conical stopper on the support rod 83 downward. The downward movement of the conical stopper on the support rod 83 compresses the high-temperature... The rubber stopper 52 deforms at high temperature, changing from a convex shape to a concave shape. The conical plug on the support rod 83 continues to move downwards and disengages from the high-temperature rubber stopper 52. At this point, the conical plug on the support rod 83 no longer blocks the high-temperature rubber stopper 52, and the heated solid-liquid mixture flows through the high-temperature rubber stopper 52 onto the filter screen 85. The filter screen 85 filters out solid impurities in the solid-liquid mixture, thus separating the solid and liquid components to obtain a mixed liquid. The filtered mixed liquid flows to the bottom of the inner side of the extraction cylinder 2. As the support rod 83 moves downwards, it also drives the small magnetic ring 86 downwards. Because the small magnetic ring 86 and the large magnetic ring 84 have opposite magnetic properties, they attract each other, causing the small magnetic ring 86 to move downwards. This movement causes the large magnet ring 84 to move downwards, compressing the vertical spring 82. The downward movement of the large magnet ring 84 causes the filter screen 85 to move downwards, disengaging from the scraper 91. Simultaneously, the support rod 83 moves downwards and stops pulling the wire rope 94. At this point, the horizontal spring 92 resets, causing the two scrapers 91 to move closer together and contact the support rod 83. The two scrapers 91 also come into contact with each other. The winding wheel 93 guides the wire rope 94. The filter screen 85 continues to move downwards, contacting the limiting ring 88 and being stopped. Meanwhile, the small magnet ring 86 continues to move downwards, disengaging from the large magnet ring 84. The reset of the vertical spring 82 causes the large magnet ring 84 and the filter screen 85 to reset upwards together.When the filter screen 85 returns to its upward reset position, it disengages from the limiting ring 88 and comes into contact with the two scrapers 91. The filter screen 85 will collide with the scrapers 91, causing a slight vibration in the filter screen 85. This slight vibration will shake off the filtered solid impurities and remove any residual liquid from the solid impurities, reducing waste of the mixed liquid. Then, the output shaft of the motor 71 rotates in the reverse direction, causing the hexagonal cylinder 72, threaded rod 73, and hexagonal rod 74 to rotate in the reverse direction as well. As the threaded rod 73 rotates in the reverse direction, it moves upward, which in turn moves the hexagonal rod 74 upward. The upward movement of the hexagonal rod 74 will no longer compress the conical plug on the support rod 83. At this time, the support rod 83 will be springy under the action of the vertical spring 82. Under the action of force, the support rod 83 moves upward, which drives the small magnetic ring 86 to move upward and pulls the steel wire rope 94. The steel wire rope 94 is pulled, which drives the two scrapers 91 to move away from each other. The movement of the scrapers 91 scrapes the solid impurities on the filter screen 85 and scrapes the solid impurities on the filter screen 85 to the two sides of the middle of the extraction cylinder 2. The operator can first remove the two pins 31, then take out the two plate covers 3, and clean the solid impurities on the two sides of the middle of the extraction cylinder 2. Then, the two plate covers 3 are put back into the two sides of the middle of the extraction cylinder 2. The plate covers 3 will squeeze the horizontal spring 92, causing the horizontal spring 92 to be compressed. Then the operator removes the pins 31. 1. Reinsert the pin 31 onto the extraction cylinder 2, causing it to limit the position of the cover 3. The conical plug on the support rod 83 moves upward and contacts the high-temperature rubber stopper 52, squeezing it and restoring it from a concave to a convex shape, ensuring a tight fit. Then, the operator starts the water pump 101, which draws the liquid from the bottom of the inner side of the extraction cylinder 2 into the three-way connecting pipe 103 through the suction pipe 102. The liquid then flows through the three-way valve core 104 into the return pipe 105, and then back into the extraction cylinder 2 through the return pipe 105. The operator then opens the top cover 5 again and adds the extracted solid impurities to the... The mixture is then transferred to extraction cylinder 2, and the top cover 5 is tightened to reheat the solid-liquid mixture using heating wire 51, while simultaneously stirring. This process is repeated to heat and filter the mixture multiple times, thereby refining rubidium, cesium, and lithium from the solid impurities. Simultaneously, the liquid is deslag-removed to reduce waste of rubidium, cesium, and lithium. After deslag removal, the operator rotates the three-way valve core 104 180 degrees to prevent it from blocking the outlet pipe 106. The liquid from the three-way connecting pipe 103 then drains from the outlet pipe 106, resulting in a higher purity liquid. The operator then proceeds with the next lithium extraction operation.

[0041] Example 2

[0042] Based on Example 1, such as Figures 14-15As shown, it also includes a liquid outlet ring 111 and a liquid outlet nozzle 12. The liquid outlet ring 111 is fixedly connected to the upper part of the inner wall of the extraction cylinder 2. The liquid outlet ring 111 is connected to the other end of the return pipe 105. Several liquid outlet nozzles 12 are connected to the inner wall of the liquid outlet ring 111.

[0043] The liquid flowing out of the liquid outlet pipe 106 will enter the liquid outlet ring 111 and be evenly sprayed onto the high-temperature rubber stopper 52 through several liquid outlet nozzles 12, so that the heating wire 51 can heat the liquid more fully and quickly, thereby improving the refining efficiency of rare metal elements such as rubidium and cesium and greatly reducing the waste of rare resources.
