Description

Technical Field

[0001] This utility model relates to the field of titanium-based adsorbent processing, and in particular to a composite structure device for enhancing the resistance to solvent damage of titanium-based adsorbents. Background Technology

[0002] Titanium-based adsorbents are highly efficient adsorbent materials used for lithium extraction from salt lakes and lithium-ion battery recycling. They are selective adsorbents, mainly used for lithium extraction from salt lakes and various lithium-containing liquids. They have advantages such as high selectivity, high adsorption capacity and long service life. They are prepared through nano-hybridization, lithium-ion imprinting and other technologies, and have high adsorption performance and memory effect, enabling them to selectively adsorb lithium ions in high-salinity environments.

[0003] Currently, enhancing the anti-dissolution performance of titanium-based adsorbents is one of the key challenges in lithium extraction technology from salt lakes. One such technology is the composite method, which involves mixing a titanium-based adsorbent precursor with a framework resin to obtain a composite. This composite is then melt-extruded and spun, followed by stretching, heat setting, extraction, washing, and pelletizing to obtain high-performance titanium-based adsorbent particles. However, the mixing of the titanium-based adsorbent precursor and framework resin is typically done directly in the hopper of a melt extruder. Because the mixing structure within the hopper is relatively simple, the mixing efficiency is low, reducing the production efficiency of high-performance titanium-based adsorbent particles.

[0004] Therefore, we propose a composite structure device to enhance the resistance of titanium-based adsorbents to solvent damage. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a composite structure device to enhance the anti-dissolution performance of titanium adsorbents, which solves the problem that the mixing efficiency of titanium adsorbent precursors and skeleton resins in the hopper is low due to the relatively simple stirring structure in the hopper of the melt extruder.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a composite structure device for enhancing the anti-solution performance of titanium-based adsorbents, comprising: a melt extruder, a hopper, and a stirring mechanism. The hopper is fixedly installed on the top of the melt extruder, and the stirring mechanism is disposed inside the hopper. The stirring mechanism includes a hollow shaft rotatably installed on the top of the hopper and a driving component for driving the hollow shaft to rotate. A hollow turntable is fixedly connected to the lower end of the hollow shaft, and a hollow tube is fixedly connected to the bottom of the hollow turntable. Horizontal stirring rods are rotatably installed on both sides of the hollow tube, and vertical stirring rods are rotatably installed on both sides of the bottom of the hollow turntable. A support rod is fixedly connected to the top of the hopper, and a geared disc and a first bevel gear are fixedly connected to the surface of the support rod. A second bevel gear meshing with the first bevel gear is fixedly connected to one end of the horizontal stirring rod, and a planetary gear meshing with the geared disc is fixedly connected to the upper end of the vertical stirring rod.

[0007] Preferably, feed pipes are fixedly connected to both sides of the top of the hopper.

[0008] Preferably, the side wall of the hopper is provided with a jacket, and a heating plate is provided in the jacket.

[0009] Preferably, the driving component includes a motor fixedly mounted on the top of the hopper, a main gear fixedly connected to the output end of the motor, and a driven gear fixedly connected to the upper end of the hollow shaft and meshing with the main gear.

[0010] Preferably, a housing is fixedly installed on the top of the hopper, and the upper end of the support rod is fixedly connected to the housing.

[0011] Preferably, a guide slip ring is fixedly connected to the top of the hollow turntable, and an annular slide rail is fixedly connected to the inner top wall of the hopper, with the guide slip ring sliding within the annular slide rail.

[0012] Preferably, the stirring mechanism further includes a scraper disposed on the inner wall of the hopper.

[0013] Preferably, both ends of the scraper are fixedly connected to connecting rods, and the two connecting rods are respectively fixedly connected to the hollow turntable and the hollow tube.

[0014] Compared with the prior art, the beneficial effects of this utility model include:

[0015] By setting up a stirring mechanism, during mixing, the drive unit can be activated to rotate the hollow shaft, causing the hollow shaft, hollow turntable, and hollow tube to rotate synchronously. The hollow tube and hollow turntable respectively drive the horizontal stirring rod and the vertical stirring rod to rotate around the hollow shaft. At the same time, the horizontal stirring rod drives the second bevel gear to roll around the first bevel gear, causing the second bevel gear to drive the horizontal stirring rod to rotate. Meanwhile, the vertical stirring rod drives the planetary gear to roll around the gear plate, causing the planetary gear to drive the vertical stirring rod to rotate. This allows the horizontal and vertical stirring rods to perform multi-directional stirring of the mixture in the hopper, improving the mixing efficiency of the titanium-based adsorbent precursor and the skeleton resin, thereby improving the production efficiency of high-performance titanium-based adsorbent particles.

[0016] By setting up a scraper, when the hollow turntable rotates, the scraper can be driven to rotate through the connecting rod, so that the scraper can clean the mixture adhering to the inner wall of the hopper, reducing the residue of the mixture on the inner wall of the hopper.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] According to the embodiments of this utility model, combined with Figures 1-4 As shown. A composite structure device for enhancing the anti-solution performance of titanium-based adsorbents includes: a melt extruder 1, a hopper 2, and a stirring mechanism 3. The hopper 2 is fixedly installed on the top of the melt extruder 1. Feed pipes 21 are fixedly connected to both sides of the top of the hopper 2.

A jacket is provided in the side wall of the hopper 2, and a heating plate 22 is provided in the jacket. The mixture in the hopper 2 can be heated by the heating plate 22.

[0028] Reference Figure 3 and Figure 4A stirring mechanism 3 is installed inside the hopper 2. The stirring mechanism 3 includes a hollow shaft 31 rotatably mounted on the top of the hopper 2 and a driving component 32 for driving the hollow shaft 31 to rotate. A hollow turntable 33 is fixedly connected to the lower end of the hollow shaft 31. A hollow tube 34 is fixedly connected to the bottom of the hollow turntable 33. Horizontal stirring rods 35 are rotatably mounted on both sides of the hollow tube 34. Vertical stirring rods 36 are rotatably mounted on both sides of the bottom of the hollow turntable 33. A support rod 37 is fixedly connected to the top of the hopper 2. A housing 23 is fixedly mounted on the top of the hopper 2. The upper end of the support rod 37 is fixedly connected to the housing 23. The support rod 37 coaxially passes through the hollow shaft 31, the hollow turntable 33, and the hollow tube 34. A gear 38 and a first bevel gear 39 are fixedly connected to the surface of the support rod 37. A second bevel gear 310 meshing with the first bevel gear 39 is fixedly connected to one end of the horizontal stirring rod 35. The vertical stirring rod... The upper end of 36 is fixedly connected to a planetary gear 311 that meshes with the gear disk 38. By setting the stirring mechanism 3, during mixing, the drive component 32 can be activated to drive the hollow shaft 31 to rotate, so that the hollow shaft 31, hollow turntable 33 and hollow tube 34 rotate synchronously. The hollow tube 34 and hollow turntable 33 respectively drive the horizontal stirring rod 35 and the vertical stirring rod 36 to rotate around the hollow shaft 31. At the same time, the horizontal stirring rod 35 drives the second bevel gear 310 to roll around the first bevel gear 39, so that the second bevel gear 310 drives the horizontal stirring rod 35 to rotate. Meanwhile, the vertical stirring rod 36 drives the planetary gear 311 to roll around the gear disk 38, so that the planetary gear 311 drives the vertical stirring rod 36 to rotate. This allows the horizontal stirring rod 35 and the vertical stirring rod 36 to perform multi-directional stirring of the mixture in the hopper 2, improving the mixing efficiency of the titanium adsorbent precursor and the skeleton resin, thereby improving the production efficiency of high-performance titanium adsorbent particles.

[0029] Specifically, the drive unit 32 includes a motor 321 fixedly installed on the top of the hopper 2, a main gear 322 fixedly connected to the output end of the motor 321, and a driven gear 323 fixedly connected to the upper end of the hollow shaft 31 and meshing with the main gear 322. The motor 321 can be started to drive the main gear 322 to rotate, which in turn drives the driven gear 323 to rotate, and the driven gear 323 drives the hollow shaft 31 to rotate.

[0030] Furthermore, a guide slip ring 312 is fixedly connected to the top of the hollow turntable 33, and an annular slide rail 313 is fixedly connected to the inner top wall of the hopper 2. The guide slip ring 312 slides within the annular slide rail 313. By setting the guide slip ring 312 and the annular slide rail 313, the hollow turntable 33 can be guided, thereby improving the stability of the hollow turntable 33 during rotation.

[0031] Furthermore, the mixing mechanism 3 also includes a scraper 314 disposed on the inner wall of the hopper 2. Both ends of the scraper 314 are fixedly connected to connecting rods 315. The two connecting rods 315 are fixedly connected to the hollow turntable 33 and the hollow tube 34, respectively. By setting the scraper 314, when the hollow turntable 33 rotates, the connecting rods 315 can drive the scraper 314 to rotate, so that the scraper 314 can clean the mixture adhering to the inner wall of the hopper 2 and reduce the residue of the mixture on the inner wall of the hopper 2.

[0032] In practical use, the working principle of this utility model is as follows:

[0033] First, the titanium-based adsorbent precursor, skeleton resin, pore-forming agent and plasticizer are added to the hopper 2 in a certain proportion through the feed pipe 21, so that the heating plate 22 heats the mixture in the hopper 2.

[0034] Then, the motor 321 is started to drive the main gear 322 to rotate, which in turn drives the driven gear 323 to rotate, which in turn drives the hollow shaft 31 to rotate. This causes the hollow shaft 31, the hollow turntable 33, and the hollow tube 34 to rotate synchronously. The hollow tube 34 and the hollow turntable 33 drive the horizontal stirring rod 35 and the vertical stirring rod 36 to rotate around the hollow shaft 31, respectively. At the same time, the horizontal stirring rod 35 drives the second bevel gear 310 to roll around the first bevel gear 39, which in turn drives the horizontal stirring rod 35 to rotate. Meanwhile, the vertical stirring rod 36 drives the planetary gear 311 to roll around the gear disk 38, which in turn drives the vertical stirring rod 36 to rotate. This allows the horizontal stirring rod 35 and the vertical stirring rod 36 to perform multi-directional stirring of the mixture in the hopper 2, ensuring that the titanium-based adsorbent precursor and the skeleton resin are fully mixed.

[0035] Next, the valve of hopper 2 is opened to add the mixture in hopper 2 into melt extruder 1, and then it is melt extruded and spun. After stretching, heat setting, extraction, and washing, it is granulated to obtain high-performance titanium adsorbent particles.

[0036] In summary, this composite structure device for enhancing the anti-solution performance of titanium-based adsorbents, by setting up a stirring mechanism 3, can perform multi-directional stirring of the mixture in the hopper 2, improve the mixing efficiency of the titanium-based adsorbent precursor and the framework resin, and thus improve the production efficiency of high-performance titanium-based adsorbent particles.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
