Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of impurity removal technology, and more specifically, to a circulating mother liquor impurity removal device. Background Technology
[0002] The raw material used in the production of alumina is bauxite, which contains various impurities, including organic matter. Although the content is low, a large amount of bauxite is required in the alumina preparation process. The sodium aluminate solution obtained after the mother liquor treatment contains organic matter. In addition, flocculants, defoamers and other solvents are added in the production process, which will also increase the organic matter content in the system. As the running time increases, impurities are formed, which will have an adverse effect on the subsequent evaporation unit of the raw liquid tank.
[0003] Currently, most factories use traditional methods to clean impurities settled at the bottom of the raw material tank. The raw material tank has an opening for maintenance or cleaning. Workers use simple tools such as shovels and homemade scrapers to scrape off the impurities, removing small amounts each time and requiring multiple operations. Utility Model Content

[0045] like Figures 1-3 The diagram illustrates a circulating mother liquor impurity cleaning device according to an embodiment of this disclosure. A hook is designed on the mother liquor tank. When not in use, a first scraper 11 is hung on the hook. When in use, the first scraper 11 is removed, and a user holds the first scraper 11 to scrape impurities from the bottom of the mother liquor tank into a receiving chamber 231. A receiving component 2 can be mounted on a base with wheels, which are set to roll on the ground, making the receiving component 2 easy to move. When the first scraper 11 scrapes impurities to the edge of the mother liquor tank, the receiving component 2 is moved to a suitable position so that the receiving chamber 231 is aligned with the impurities scraped out by the first scraper 11, thereby collecting the impurities.
[0046] This device can effectively clean impurities from the bottom of the raw liquid tank, preventing impurities from accumulating in the tank and affecting the quality of the mother liquor. Impurities are cleaned by the movement of the first scraper 11, and the scraped-out impurities are collected by the receiving part 2, achieving effective collection of impurities and facilitating subsequent processing.
[0047] For example, such as Figure 3 As shown, the first scraper 11 engages with the bottom of the raw liquid tank, and the handle 12 is fixed in the middle of the first scraper 11. The operator can manually push the first scraper 11 along the guide rail by holding the handle 12, thereby cleaning the impurities at the bottom of the raw liquid tank. During the cleaning process, the operator can control the moving speed and direction of the first scraper 11 as needed to ensure that the impurities can be effectively scraped off.
[0048] The handle 12 is designed to allow operators to manually control the movement of the first scraper 11. It is easy to operate and can adjust the cleaning position and intensity of the first scraper 11 in a timely manner according to the actual situation, thereby improving the cleaning effect.
[0049] For example, such as Figure 3As shown, a groove 111 is provided on the first scraper 11, allowing the second scraper 13 and the third scraper 14 to slide along the length of the first scraper 11. A limiting device can be provided on the first scraper 11 to prevent the second scraper 13 and the third scraper 14 from completely sliding out of the groove. There can be multiple second scraper 13s and third scraper 14s. Multiple second scraper 13s slide relative to each other along the length of the first scraper 11, which can extend the cleaning area of the first scraper 11, and the same applies to the third scraper 14.
[0050] In practical use, when it is necessary to expand the cleaning range of the first scraper 11, the second scraper 13 and the third scraper 14 can be manually pulled to slide in opposite directions along the length of the first scraper 11, thereby increasing the overall width of the first scraper 11 and improving cleaning efficiency.
[0051] The sliding configuration of the second scraper 13 and the third scraper 14 allows the cleaning width of the first scraper 11 to be adjusted according to the actual situation of the raw liquid tank, enabling it to adapt to raw liquid tanks of different widths and improving the versatility and cleaning efficiency of the first scraper 11.
[0052] For example, such as Figure 4 As shown, the elastic element 15 can be a spring, with one end fixed to the first scraper 11 and the other end fixed to the second scraper 13 and the third scraper 14 respectively. In the initial state, the spring is in a naturally extended state. When no external force is applied, the spring will push the second scraper 13 and the third scraper 14 outward, causing them to move away from each other.
[0053] When it is necessary to narrow the width of the first scraper 11, manually overcome the spring force and move the second scraper 13 and the third scraper 14 closer to the first scraper 11. When the external force disappears, the spring will automatically push the second scraper 13 and the third scraper 14 back to their original positions.
[0054] For example, such as Figure 4 As shown, the extensions 131 of the second scraper 13 and the third scraper 14 can be integrally formed with the scraper body. When the second scraper 13 and the third scraper 14 move away from each other under the action of the elastic member 15, the extensions 131 will move with the scraper and move away from the first scraper 11. The extensions 131 increase the effective cleaning length of the first scraper 11, which can better clean impurities in corners and other locations of the original liquid tank. The groove 111 provides guidance for the sliding of the second scraper 13 and the third scraper 14.
[0055] The extension 131 further expands the cleaning range of the first scraper 11, enabling the first scraper 11 to more thoroughly clean the impurities at the bottom of the raw liquid tank, improving the cleaning effect and reducing cleaning dead corners.
[0056] For example, such as Figure 3As shown, the two ends of the telescopic rod 16 are hinged to the extension part 131 and the handle 12 respectively via pins. When the operator holds the handle 12 and swings the other end of the telescopic rod 16, the other end of the telescopic rod 16 swings synchronously, thereby driving the extension part 131 to move closer to the first scraper 11.
[0057] For example, when the first scraper 11 needs to enter the raw liquid tank through a narrow channel, the operator can slide the sliding sleeve 17 on the handle 12 towards the first scraper 11. Because the sliding sleeve 17 presses against the other end of the telescopic rod 16, the other end of the telescopic rod 16 swings, causing one end of the telescopic rod 16 to move the extension part 131 closer to the first scraper 11, thus reducing the overall size of the first scraper 11. The telescopic rod 16 allows the operator to easily control the position of the extension part 131 via the handle 12, thereby adjusting the overall size of the first scraper 11. This is very practical in operations such as the first scraper 11 entering or exiting the raw liquid tank, improving the ease of operation and adaptability of the device. To strengthen the structure, the sliding sleeve 17 can be threaded onto the handle 12. After rotating the sliding sleeve 17, it can slide relative to the handle, causing the telescopic rod 17 to swing. The threaded sliding sleeve 17 can also fix the swing angle of the telescopic rod, further controlling the extension range of the second scraper 13 and the third scraper 14. The sliding sleeve 17 is cylindrical and is fitted onto the handle 12. There is a gap between the end of the sliding sleeve 17 near the first scraper 11 and the handle 12. The telescopic rod 16 can be stuck in the gap after swinging.
[0058] For example, such as Figure 2 As shown, the mounting frame 22 is mounted on a wheeled base and can move on a ground track. The receiving bucket 23 is height-adjustable relative to the mounting frame 22, and can be adjusted to accommodate different types of raw liquid tanks. In actual operation, by adjusting the height of the receiving bucket 23 according to the height of the raw liquid tank and the position of the impurities scraped out by the first scraper 11, the receiving chamber 231 can be used to receive the impurities. The adjustable height of the receiving bucket 23 can accommodate raw liquid tanks of different heights and different positions of the impurities scraped out by the first scraper 11, improving the versatility and adaptability of the device and ensuring that impurities fall accurately into the receiving chamber 231.
[0059] For example, such as Figure 2 As shown, the two ends of the first connecting rod 24 and the second connecting rod 25 are hinged to the mounting frame 22 and the receiving bucket 23 respectively via pins. A drive mechanism, such as an electric motor, is installed on the mounting frame 22. When the motor rotates, it drives the first connecting rod 24 and the second connecting rod 25 to swing synchronously. Since the first connecting rod 24 and the second connecting rod 25 are parallel and have the same structure, their synchronous swing will drive the receiving bucket 23 to perform a translational motion. In this way, when adjusting the height of the receiving bucket 23, the receiving bucket 23 can remain horizontal, preventing impurities in the receiving chamber 231 from spilling out due to tilting.
[0060] By utilizing the parallelogram structure of the first link 24 and the second link 25, the receiving bucket 23 is kept in translation during the height adjustment process, which ensures the stability of the receiving bucket 23, prevents impurities from spilling out, and improves the reliability of receiving materials.
[0061] For example, such as Figure 2 As shown, threaded holes are provided at the four corners of the mounting frame 22, and the support legs 26 are threaded rods that mate with the threaded holes on the mounting frame 22. Operators can rotate the support legs 26, which have wheels that contact the ground. Due to the threads, the rotation of the support legs 26 causes the mounting frame 22 to rise or fall. When the height of the mounting frame 22 needs to be adjusted, the four support legs 26 are rotated to raise or lower the mounting frame 22 to a suitable height to adapt to different working scenarios. The threaded adjustment method of the support legs 26 allows for convenient adjustment of the height of the mounting frame 22, further improving the adaptability of the receiving part 2 to different working environments. Moreover, this adjustment method is simple, reliable, and low-cost.
[0062] For example, such as Figure 2 As shown, a guide hole is provided on the mounting frame 22, and the support block 27 is installed in the guide hole. When cleaning impurities at the bottom of the raw material tank, to prevent the mounting frame 22 from shaking on the ground, the support block 27 needs to be lowered so that it supports the mounting frame 22, preventing the wheel from rotating and causing impurities to spill onto the ground. For example, the support block 27 and the mounting frame 22 are also threadedly connected. When the support block 27 needs to support the mounting frame 22, simply rotate the support block 27 so that its extension length is greater than the extension length of the support leg 26. The support block 27 contacts the ground, and the wheel is suspended. The support block 27 can move up and down stably, avoiding the shaking of the support leg 26 during rotation and ensuring the smoothness of the lifting and lowering of the mounting frame 22.
[0063] The support block 27 improves the stability of the support leg 26 when it rotates, making the lifting of the mounting frame 22 more stable and reliable, further enhancing the overall stability of the receiving part 2, and facilitating the accurate receipt of impurities.
