Description

Technical Field

[0001] This utility model relates to the field of concentration equipment technology, and in particular to a rare earth chloride salt evaporation and concentration equipment. Background Technology

[0002] In the production and processing of rare earth chloride salts, evaporation and concentration is a crucial step. Traditional evaporation and concentration devices often have some shortcomings. For example, during evaporation and concentration, as the water content in the solution decreases and the temperature rises, the solute in the solution easily crystallizes and precipitates on the inner wall of the concentration tank, gradually forming a thick scale layer. This scale layer greatly affects heat transfer efficiency, requiring the heating source to consume more energy to maintain the temperature required for evaporation, increasing production costs. Furthermore, uneven local temperature distribution can also affect product quality. Moreover, once material crystals adhere to the wall, cleaning is extremely difficult. If not cleaned promptly and effectively, long-term accumulation can lead to impurities being mixed into the product, reducing product purity. Additionally, the top cover of most devices is fixed with bolts. When inspection or maintenance of the concentration tank is required, disassembling the top cover necessitates using tools to tighten multiple bolts one by one, a cumbersome and time-consuming operation that greatly inconveniences daily maintenance work and reduces the overall maintenance efficiency of the device. To address these problems, this utility model proposes a rare earth chloride salt evaporation and concentration device, aiming to solve the aforementioned problems encountered during evaporation and concentration, such as wall adhesion affecting heat transfer and the inconvenience of top cover disassembly and assembly.

A cylindrical rod is slidably connected inside the connecting rod. A scraper is fixedly connected to the end of the cylindrical rod away from the connecting rod. A spring is provided between the inside of the connecting rod and one end of the cylindrical rod.

[0013] Preferably, a sealing ring is provided between the top cover and the top of the concentration tank.

[0014] Preferably, the top of the cover has a slot, and the bottom of the card block is engaged inside the slot.

[0015] Preferably, a positioning rod is fixedly connected to the side of the top cover, and a positioning block is fixedly connected to the top side of the outer shell corresponding to the position of the positioning rod, with the positioning rod inserted inside the positioning block.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, by setting an anti-sticking wall structure, the crystals on the inner wall of the concentration tank can be scraped off, preventing the liquid from crystallizing on the inner wall of the concentration tank during concentration and affecting heat transfer. At the same time, by setting a spray mechanism in conjunction with the anti-sticking wall structure, the water inlet pipe of the spray mechanism can introduce external cleaning water. The water flows through the spray pipe and sprays out from the nozzle, spraying towards the inner wall of the concentration tank. In conjunction with the anti-sticking wall structure, on the one hand, it can promptly wash away the crystals or residual materials scraped off by the scraper, and on the other hand, it can also thoroughly rinse and clean the entire inside of the concentration tank, preventing impurities from affecting subsequent evaporation and concentration operations and product quality. This achieves the purpose of cleaning the inside of the concentration tank, ensuring that the device can operate stably and efficiently for a long time, and also helps to improve the quality of the final rare earth chloride salt concentrated product.

[0018] 2. In this utility model, through the joint cooperation of the fixing block, screw, knob, and locking block, when it is necessary to disassemble the top cover, rotating the knob causes the locking block to move upward and detach from the top cover, so that the top cover can be easily removed. During installation, after placing the top cover, rotating the knob in the opposite direction causes the locking block to move downward, and the bottom surface of the locking block abuts against the top surface of the top cover, thus completing the fixing of the top cover. Compared with the traditional method of fixing the top cover with multiple bolts, this method does not require the use of tools to tighten the bolts one by one, which greatly saves the disassembly and assembly time, makes the operation more convenient, facilitates the inspection and maintenance of the inside of the concentration tank and related components of the top cover, and improves the maintainability and ease of use of the entire device.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1: As Figure 1 - Figure 6 As shown, this utility model provides a technical solution: a rare earth chloride salt evaporation and concentration device, including a concentration tank 1, an anti-sticking structure 7 and a spraying mechanism 6. The outer wall of the concentration tank 1 is fixedly connected to a shell 2. A heating wire 24 is provided inside the shell 2. A top cover 3 is provided on the top of the shell 2. A feed pipe 4 and an exhaust pipe 5 are fixedly connected to the top cover 3.

[0030] The anti-sticking structure 7 includes a motor 701, which is located on the top of the top cover 3. The output shaft of the motor 701 passes through the top cover 3 and is fixedly connected to a vertical rod 702. A connecting rod 703 is fixedly connected to the surface of the vertical rod 702. A cylindrical rod 705 is slidably connected inside the connecting rod 703. A scraper 704 is fixedly connected to the end of the cylindrical rod 705 away from the connecting rod 703. A spring 706 is provided between the inside of the connecting rod 703 and one end of the cylindrical rod 705. One end of the spring 706 is fixedly connected to the end of the cylindrical rod 705 away from the scraper 704, and the other end abuts against the bottom end of the inside of the connecting rod 703.

[0031] The spraying mechanism 6 includes a spray pipe 602, the top of which is fixedly connected to the bottom of the top cover 3. A nozzle 603 is provided at the bottom end of the spray pipe 602. A water inlet pipe 601 is fixedly connected to the top of the spray pipe 602, and the other end of the water inlet pipe 601 is connected to an external water supply mechanism. A threaded sleeve 21 is fixedly connected to the bottom of the spray pipe 602, and the top end of the nozzle 603 is threaded into the inside of the threaded sleeve 21. A turbine is fixedly connected to the bottom and middle of the upright 702. The bottom of the roller blade 18 and the concentration tank 1 is fixedly connected to the discharge pipe 20, and the discharge pipe 20 is equipped with an electric control valve 19. The motor 701 is fixedly connected to the top cover 3 by the second bolt 17. The top of the upright rod 702 is fixedly connected to the bottom of the output shaft of the motor 701 by the first bolt 16. The surface of the cylindrical rod 705 is fixedly connected to the limiting rod 22. The inner wall of the connecting rod 703 is provided with a limiting groove 23 corresponding to the position of the limiting rod 22. The limiting rod 22 is stuck inside the limiting groove 23.

[0032] The beneficial effects achieved in this embodiment 1 are as follows: By setting the anti-sticking structure 7, the motor 701 drives the upright rod 702 to rotate, thereby causing the connecting rod 703 to perform circumferential motion. Since the cylindrical rod 705 and the connecting rod 703 are connected by a spring 706 and a scraper 704 is fixed at one end of the cylindrical rod 705, the scraper 704 can always be tightly attached to the inner wall of the concentration tank 1 under the elastic action of the spring 706. During the operation of the device, even if the inner wall is uneven due to solution crystallization, the scraper 704 can adaptively and tightly scrape the wall surface, effectively removing the crystallized or sticking material on the inner wall of the concentration tank 1, avoiding the accumulation of these materials to form a scale layer that affects heat transfer, ensuring heat transfer efficiency, and enabling the evaporation and concentration process to be carried out in a stable temperature environment, which is conducive to improving product quality. At the same time, the water inlet pipe 601 in the spray mechanism 6 is connected to the external water supply mechanism, and clean water can be introduced as needed. The water flows through the spray pipe 602 and is sprayed out from the nozzle 603. The nozzle 603 is threadedly connected to the spray pipe 602 via the threaded sleeve 21, facilitating installation, disassembly, and replacement. This ensures that the nozzle 603 can stably spray water onto all parts of the inner wall of the concentration tank 1. In conjunction with the anti-sticking wall structure 7, it can promptly flush away impurities scraped off by the scraper 704 and thoroughly clean the entire interior of the concentration tank 1, preventing impurities from remaining and mixing into the product. This further ensures the purity of the product and helps extend the service life of the device, reducing equipment failures and maintenance frequency caused by scaling, impurity residues, and other issues. The turbine tumbling blades 18, fixedly connected to the bottom and middle of the upright 702, can better stir the solution in the concentration tank 1 when rotating with the upright 702, creating stronger convection, promoting uniform heating of the solution, avoiding local overheating, accelerating the evaporation rate, improving the efficiency of evaporation and concentration, and also helping to uniformly disperse the solute in the solution, ensuring that the final rare earth chloride salt concentrate product has a uniform concentration. An electrically controlled valve 19 is installed on the discharge pipe 20 at the bottom of the concentration tank 1, which can conveniently and accurately control the discharge operation. The valve can be opened or closed in a timely manner according to the concentration requirements to ensure a stable and smooth discharge process and avoid solution leakage or splashing during discharge, thus ensuring the convenience and safety of product collection. The motor 701 is fixedly connected to the top cover 3 by the second bolt 17, and the top of the upright 702 is fixedly connected to the bottom of the output shaft of the motor 701 by the first bolt 16. This connection method is simple and stable, convenient for installation and disassembly, and facilitates maintenance and repair of components such as the motor 701 and the upright 702. It ensures that the entire anti-adhesion wall structure 7 and related transmission components can operate normally and ensures the stable working state of the device. The limiting rod 22 on the surface of the cylindrical rod 705 is stuck in the limiting groove 23 on the inner wall of the connecting rod 703, which restricts the sliding direction of the cylindrical rod 705. This ensures that the scraper 704 can only move along the predetermined direction when it rotates with the connecting rod 703, making it more stable and reliable during the scraping process. It avoids abnormal situations such as scraper 704 deviation and shaking, further improving the scraping effect and the stability of the device operation.

[0033] Example 2: Figure 3 - Figure 5 As shown, several fixing blocks 8 are fixedly connected to the outer wall of the top of the outer shell 2. The screw 9 is threadedly connected to the inside of the fixing block 8. A knob 11 is fixedly connected to the top of the screw 9. A rotatable locking block 10 is provided on the screw 9. The ground of the locking block 10 abuts against the top surface of the top cover 3. A sealing ring 13 is provided between the top cover 3 and the top of the concentration tank 1. A slot 12 is opened on the top of the cover. The bottom surface of the locking block 10 is locked inside the slot 12. A positioning rod 15 is fixedly connected to the side of the top cover 3. A positioning block 14 is fixedly connected to the top side of the outer shell 2 corresponding to the position of the positioning rod 15. The positioning rod 15 is inserted into the inside of the positioning block 14.

[0034] The beneficial effects achieved in this embodiment 2 are as follows: By setting several fixing blocks 8 on the outer wall of the top of the outer shell 2, and connecting the fixing blocks 8 with screw rods 9 by threads, and connecting the top of the screw rods 9 with knobs 11 and rotatable locking blocks 10, when installing the top cover 3, the top cover 3 is placed in a suitable position so that the positioning rods 15 on the side of the top cover 3 are inserted into the corresponding positioning blocks 14 on the side of the top of the outer shell 2, achieving preliminary positioning, which facilitates the accurate insertion of the locking blocks 10 into the slots 12. Then, the knobs 11 are rotated to drive the screw rods 9 to rotate, causing the locking blocks 10 to move downwards, and the bottom surface of the locking blocks 10 is locked into the slots 12 on the top surface of the top cover 3. Inside the casing 2, the locking block 10 is designed to prevent the top cover 3 from rotating due to vibration or other reasons during the fixing process, thus ensuring the top cover 3 is firmly fixed to the casing 2. Compared with the traditional method of simply using a large number of bolts, this fixing method is simpler and faster to operate. It eliminates the need to use tools to tighten multiple bolts one by one, greatly saving disassembly and assembly time and improving the maintainability and ease of use of the device. The sealing ring 13 set between the top cover 3 and the top of the concentration tank 1 can effectively prevent the steam, solution, etc. in the tank from leaking out from the connection between the top cover 3 and the concentration tank 1 during the evaporation and concentration process, ensuring the airtightness of the device.

[0035] The working principle of this embodiment is as follows: When in use, the rare earth chloride salt solution is first transported to the concentration tank 1 through the feed pipe 4. Then, the heating wire 24 inside the outer shell 2 is activated. After the heating wire 24 is energized, it generates heat. The heat is transferred to the concentration tank 1 through the outer shell 2, which heats the rare earth chloride salt solution in the concentration tank 1, causing its temperature to gradually rise to the boiling point. The water in the solution begins to evaporate and form water vapor. The water vapor is discharged through the exhaust pipe 5. Simultaneously, the motor 701 on the top of the top cover 3 is activated. The output shaft of the motor 701 drives the upright 702 to rotate, and the connecting rod 703 on the upright 702 rotates accordingly. The scraper 704, which is fixed at one end of the cylindrical rod 705 slidably connected inside the connecting rod 703, always keeps in close contact with the inner wall of the concentration tank 1 due to the elasticity of the spring 706, and performs a scraping operation on the inner wall to prevent solution crystals and other substances from sticking to the wall and forming a scale layer that affects heat transfer efficiency. In addition, the turbine blades 18 on the upright 702 stir the solution as the upright 702 rotates, promoting uniform heating of the solution and accelerating the evaporation rate. During the concentration process, the solution continuously evaporates and concentrates. When the predetermined concentration degree is reached, the electrically controlled valve 19 on the discharge pipe 20 at the bottom of the concentration tank 1 is opened to discharge the concentrated rare earth chloride salt. The solution is stably and smoothly discharged and collected. When it is necessary to clean the inside of the concentration tank 1, the valve on the water inlet pipe 601 connected to the external water supply mechanism is opened, and water flows into the spray pipe 602 and is sprayed onto the inner wall of the concentration tank 1 through the nozzle 603. In conjunction with the scraper 704, the scraped impurities are washed away and the inside of the tank is thoroughly rinsed. As for the installation and removal of the top cover 3, during installation, the positioning rod 15 and the positioning block 14 are used for initial positioning. Then, the screw 9 is driven by rotating the knob 11 to press down the locking block 10 to fix the top cover 3. During removal, the operation is reversed. The locking block 10 is moved up and removed from the top cover 3 by rotating the knob 11. This facilitates the maintenance of the device. All components of the entire device work together to achieve efficient and stable evaporation and concentration of rare earth chloride salt solution and convenient maintenance of the device.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
