Description

Technical Field

[0001] This utility model relates to the field of adsorbent technology, specifically to a granulation device for lithium adsorbent. Background Technology

[0002] Lithium adsorbents are materials used to effectively extract lithium from various media, with particularly significant application value in lithium extraction from high-temperature, high-salinity brines and salt lakes.

[0003] Typically, an extrusion granulator is used when forming adsorbent powder. The adsorbent powder and other auxiliary materials are added to the extruder, where they are thermally mixed and continuously extruded through the extrusion orifice. Then, a rotating cutter continuously cuts the extrusion orifice into granular adsorbent.

[0004] However, when the adsorbent powder is added to the extruder through the feeding hopper, the adsorbent powder may clump together, which can easily cause blockage at the extruder inlet and affect continuous production. Utility Model Content

[0005] The main objective of this invention is to provide a granulation device for lithium adsorbents, thereby solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides a granulation device for lithium adsorbent, including an extruder body, a cutting assembly, a filter frame, a vibrating component, and a striking assembly.

[0007] An extrusion hole is provided at the right end of the extruder body, and a feed hopper is provided on the upper left side of the extruder body;

[0008] The cutting assembly is located on the right side of the extruder body, and the cutting assembly has a rotatable cutting blade;

[0009] The filter frame is detachably installed in the feed hopper via a hook, and a filter screen is provided at the bottom of the filter frame;

[0010] The vibrating element is installed inside the feed hopper and is used to cause the filter screen to vibrate.

[0011] The striking assembly is located at the lower end of the feed hopper, and the striking assembly has a rotatable striking column.

[0012] The aforementioned beneficial effects are as follows: by hooking the upper outer wall of the feeding hopper, the filter frame can be stably placed inside the feeding hopper. The adsorbent powder is added into the filter frame, and the filter screen filters the adsorbent powder, leaving clumps in the filter frame. At the same time, the vibrating component causes the filter screen to vibrate, accelerating the filtration of the adsorbent powder. When cleaning is required, the filter frame can be moved upward to quickly clean the clumps in the filter frame. After filtration, the adsorbent powder is again struck by a rotatable striking column to knock off any remaining clumps, ensuring that there are no clumps in the adsorbent powder. Then, it falls into the extruder, is heated and melted, and is continuously extruded from the extrusion orifice. At the same time, a rotatable cutting blade cuts the extrusion orifice, cutting out uniformly sized granular adsorbent. This avoids the presence of clumps in the adsorbent powder and ensures continuous production.

[0013] In a preferred embodiment, the hooks are four in number, and the four hooks are respectively located at the four corners of the upper end of the filter frame.

[0014] In a preferred embodiment, the vibrating element has two sets, which are respectively disposed on both sides inside the feed hopper. Each set of the vibrating element includes a cam and a first rotating shaft, with the cam disposed on the first rotating shaft.

[0015] In a preferred embodiment, there are multiple striking columns arranged radially along a second rotating shaft located at the lower end of the feed hopper and connected to a motor.

[0016] In a preferred embodiment, the cutting blade is mounted on a rotating shaft, the rotating shaft is mounted on an arc-shaped baffle, and the lower end of the arc-shaped baffle has a discharge port. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] This utility model provides a granulation device for lithium adsorbent, including an extruder body 10, a cutting component 20, a filter frame 30, a vibrating component 40, and a striking component 50.

[0024] The right end of the extruder body 10 is provided with an extrusion hole 11, and the upper left side of the extruder body 10 is provided with a feed hopper 13.

[0025] The cutting assembly 20 is located on the right side of the extruder body 10, and the cutting assembly 20 has a rotatable cutting blade 21;

[0026] The filter frame 30 is detachably installed in the feed hopper 13 via a hook 31, and a filter screen 32 is provided at the bottom of the filter frame 30.

[0027] The vibrating element 40 is disposed inside the feed hopper 13, and the vibrating element 40 is used to cause the filter screen 32 to vibrate.

[0028] The striking component 50 is disposed at the lower end of the feed hopper 13, and the striking component 50 has a rotatable striking column 51.

[0029] During operation, the filter frame 30 is stably placed inside the hopper by hooking the upper outer wall of the feeding hopper with the hook 31. The adsorbent powder is added into the filter frame 30, and the filter screen 32 filters the adsorbent powder, leaving clumps inside the filter frame 30. At the same time, the vibrating element 40 causes the filter screen 32 to vibrate, accelerating the filtration of the adsorbent powder. When cleaning is required, the filter frame 30 is moved upward to quickly clean the clumps inside the filter frame 30. After filtration, the adsorbent powder is again struck by the rotatable striking column 51 to knock off any remaining clumps, ensuring that there are no clumps in the adsorbent powder. Then, it falls into the extruder and is heated and continuously extruded from the extrusion hole 11. At the same time, the rotatable cutting blade 21 cuts the position of the extrusion hole 11 to cut out uniformly sized granular adsorbent, thus avoiding the presence of clumps in the adsorbent powder and ensuring continuous production.

[0030] In addition, the filter frame is detachably installed inside the feeding hopper, which also facilitates subsequent cleaning of the filter frame.

[0031] Preferably, there are four hooks 31, which are respectively disposed at the four upper corners of the filter frame 30.

[0032] After the filter frame 30 is placed into the feeding hopper, it is hung at the four corners of the upper end of the feeding hopper by four hooks 31, so that the filter frame 30 can be stably placed in the feeding hopper. When the filter frame 30 is removed, the personnel can simply move the filter frame 30 upwards.

[0033] Preferably, the vibrating element 40 has two sets, and the two sets of vibrating elements 40 are respectively arranged on both sides inside the feed hopper 13. Both sets of vibrating elements include a cam 41 and a first rotating shaft 42, and the cam 41 is arranged on the first rotating shaft 42.

[0034] The two rotating shafts are driven to rotate by drive motors. The first rotating shaft 42 drives the cam 41 to rotate. The cam 41 continuously contacts the filter screen 32, causing the filter screen 32 to move up and down and vibrate.

[0035] Preferably, there are multiple striking columns 51, which are arranged along the radial direction of the second rotating shaft 52. The second rotating shaft 52 is located at the lower end of the feed hopper 13 and is connected to the motor 53.

[0036] The motor 53 drives the second rotating shaft 52 to rotate, and the second rotating shaft 52 drives multiple striking columns 51 to rotate. The rotating striking columns 51 continuously strike the filtered adsorbent powder.

[0037] Preferably, the cutting blade 21 is mounted on the rotating shaft 22, the rotating shaft 22 is mounted on the arc-shaped baffle 23, and the lower end of the arc-shaped baffle 23 is provided with a discharge port 24.

[0038] The motor structure drives the rotating shaft 22 to rotate, which in turn drives the cutting blade 21 to rotate, and the cutting blade 21 cuts the adsorbent into particles.

[0039] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
