Description

Technical Field

[0001] This utility model relates to the fields of chemistry and metallurgy, and more specifically, to a distillation device for waste containing germanium dioxide. Background Technology

[0002] Germanium is a rare, dispersed metal, with an abundance of only 4 × 10⁻⁴% in the Earth's crust. It is mainly found in non-ferrous metal ores and coal mines, and apart from very few germanium ore deposits, there are almost no standalone germanium deposits. The raw materials for extracting germanium mainly include germanium-enriched products from various metal smelting processes, germanium-containing coal combustion products, and waste materials from germanium processing.

[0003] The existing publicly available technology, application number CN201010622450.6, discloses a method for producing high-purity germanium dioxide, which includes the following steps: 1) detecting and roasting germanium-containing waste; 2) chlorinating, distilling, redistilling, and purifying by distillation to obtain high-purity GeCl4; 3) hydrolyzing GeCl4 to prepare GeO2; and 4) washing, centrifuging, microwave drying, and packaging the hydrolysis products. The advantages of this invention are: reasonable process, high yield, increased production capacity, and reduced labor intensity for workers.

[0004] Based on the aforementioned patents and existing production conditions, it can be noted that when using germanium dioxide-containing waste, a distillation kettle is used for distillation treatment. During the operation of the distillation kettle, a certain amount of deposits will be generated inside due to the reaction of the material. If the deposits are not dealt with during the reboiler processing, it will affect the working efficiency of the distillation kettle. Traditional processing requires shutdown for operation, and the overall operation process is relatively complex and cumbersome, with high labor intensity for personnel, and the overall use effect is not ideal.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0028] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, a distillation device for germanium dioxide-containing waste is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a distillation device for germanium dioxide waste according to an embodiment of the present invention includes a distillation kettle 1 and a support leg 16. A filter plate 20 is installed at the bottom of the interior of the distillation kettle 1. The top of the filter plate 20 is circular, and the bottom is rectangular. A limiting rod 19 is installed above the filter plate 20 on the inner surface of the distillation kettle 1. A scraper 15 is sleeved around the outer periphery of the limiting rod 19. The bottom of the scraper 15 contacts the rectangular area inside the filter plate 20. A first push rod 13 is fixedly installed on one side of the scraper 15. One end of the first push rod 13 passes through one side of the distillation kettle 1 and is connected to a first cylinder 14. A sealing ring is provided at the contact position between the first push rod 13 and the distillation kettle 1. Openings are symmetrically opened on both sides of the scraper 15 on the two sides of the surface of the distillation kettle 1. A sealing block 22 is provided inside the opening for sealing. A sealing block 22 is installed on the outer side of the sealing block 22 on the surface of the distillation kettle 1. A second push rod 23 is installed on one side of the impurity tube 21 and the sealing block 22. One end of the second push rod 23 passes through one side of the impurity tube 21 and is connected to the second cylinder 24. The functional advantages of the filter plate 20 and scraper 15 assembly are as follows: efficient solid-liquid separation: the circular top of the filter plate 20 is adapted to the shape of the inner cavity of the distillation vessel 1, and the rectangular bottom concentrates the deposited impurities, which is convenient for the scraper 15 to clean in a directional manner; automated impurity cleaning: the first cylinder 14 drives the scraper 15 to push solid impurities into the impurity tube 21 without stopping the machine, reducing manual intervention; the limiting rod 19 guides: it ensures that the movement trajectory of the scraper 15 is accurate and avoids incomplete impurity cleaning caused by deviation; the second cylinder 24 drives the sealing block 22 to open and close quickly, opening the impurity tube 21 only during impurity cleaning to avoid impurity leakage during distillation. The sealing block 22 fits tightly with the opening to ensure that the equipment has no risk of leakage under high pressure.

[0031] In one embodiment, a sealing plate 6 is installed in the middle of the interior of the distillation vessel 1. Several sets of sealing grooves 7 are uniformly and through-cut on the surface of the sealing plate 6. Fixing plates 12 are symmetrically installed on both sides of the interior of the distillation vessel 1 below the sealing plate 6. A sealing cylinder 11 is installed on the top of the fixing plate 12. A moving rod 10 is slidably connected to the interior of the sealing cylinder 11. A connecting plate 26 is installed on the top of the moving rod 10. Several sets of sealing rods 9 are uniformly installed on the surface of the connecting plate 26, and the sealing rods 9 correspond one-to-one with the sealing grooves 7. Furthermore, through grooves are provided around the sealing rods 9 on the surface of the connecting plate 26. After the sealing rods 9 are inserted into the sealing grooves 7, they separate the upper liquid layer from the lower solid-liquid mixture, preventing impurities from flowing back and interfering with the distillation process.

[0032] In one embodiment, a discharge pipe 18 is installed at the bottom of the distillation vessel 1, and the discharge pipe 18 has a three-way structure. Valves are provided at both ends of the discharge pipe 18. A chemical pump 17 is installed at one end of the discharge pipe 18. One end of the chemical pump 17 is connected to the top of the interior of the distillation vessel 1 through a circulation pipe 5. The chemical pump 17 re-injects the filtered liquid into the top of the distillation vessel 1 through the circulation pipe 5, reducing raw material waste and improving distillation efficiency. The three-way discharge pipe 18 allows for flexible switching of the liquid discharge mode (discharge or circulation) to adapt to the needs of different process stages.

[0033] In one embodiment, support legs 16 are symmetrically installed on both sides of the bottom of the distillation vessel 1. The support legs 16 provide stable support, ensure the balance of the equipment during operation, and prevent tilting caused by vibration or load changes.

[0034] In one embodiment, the top of the distillation vessel 1 is provided with several sets of feed pipes 3 and distillation pipes.

[0035] In one embodiment, air pumps 8 are symmetrically positioned on both sides of the distillation vessel 1. The air pumps 8 are connected to the sealing cylinder 11 via air supply pipes 25. The air pumps 8 provide stable power and have a fast response speed. The sealing cylinder 11 is designed to prevent gas leakage and ensure system reliability.

[0036] In one embodiment, a stirring paddle 2 is installed at the top of the interior of the distillation vessel 1. One end of the stirring paddle 2 passes through one side of the distillation vessel 1 and is connected to the motor 4. The stirring paddle 2 promotes full contact of the reactants, avoids local overheating or uneven reaction, improves the purity of the distillation product, and reduces the accumulation rate of solid impurities at the bottom of the vessel by continuous stirring, thus extending the continuous operation time of the equipment.

[0037] In one embodiment, the size of the sealing groove 7 is smaller than the size of the waste material but larger than the size of the generated impurities. The design of the sealing groove 7 (smaller than the waste material but larger than the impurities) combined with the lifting and lowering of the sealing rod 9 enables precise filtration and interception of impurities.

[0038] Working principle: In actual use, personnel can add germanium dioxide-containing waste and corresponding liquid into the distillation vessel 1 through the feed pipe 3. The distillation vessel 1 then distills the germanium dioxide-containing material. As distillation and reaction continue, a large amount of solid impurities will precipitate. These impurities can then fall through the large-diameter sealing groove 7 onto the lower filter plate 20. The filter plate 20 has a circular top and rectangular bottom structure, allowing the falling impurities to settle at the rectangular bottom. Then, the operation of the air pump 8 introduces gas into the air supply pipe 25. The gas then enters the sealing cylinder 11 along the air supply pipe 25. As the gas continuously enters, it lifts the moving rod 10, causing the connecting plate 26 to move upwards, thus inserting the sealing rod 9 on its surface into the sealing groove 7. This achieves the separation of the upper liquid layer from the lower solid-liquid mixture. Opening the valve on one side of the discharge pipe 18 at the bottom allows the liquid filtered by the filter plate 20 at the bottom to be added back to the top of the distillation vessel 1 through the circulation pipe 5, facilitating subsequent distillation. Since the liquid in the solid-liquid composition has been discharged, only solid impurities remain at the bottom of the distillation vessel 1. At this point, the operation of the second cylinder 24 can drive the second push rod 23 to move outward, thereby opening the sealing block 22 in contact with the distillation vessel 1. Simultaneously, the extension and retraction of the first cylinder 14 can drive the first push rod 13 to move left and right, thereby driving the push plate to reciprocate at the bottom of the filter plate 20. This pushes the solid impurities on its surface into the impurity pipe 21 for discharge, effectively removing impurities without affecting the normal operation of the distillation process. This effectively reduces the labor intensity of personnel and facilitates better use. The device as a whole has the advantages of convenient impurity handling, good impurity handling effect, and labor-saving operation.
