[0026] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 6 The embodiments are described in detail below.

[0027] This embodiment provides a sodium-based bentonite grinding device, as shown in the attached figure, including multiple filtering mechanisms 3, multiple pulverizing mechanisms 4, and a grinding mechanism 5, wherein:

[0028] The bottom of the filtration mechanism 3 is provided with a discharge mechanism 1, which includes a collection frame 101, a support base 102, and a guide frame 103. The collection frame 101 is threadedly connected to the bottom of the positioning ring 301. The support base 102 is fixedly installed on the bottom of the collection frame 101. The guide frame 103 is fixedly connected to the outer wall of the collection frame 101. The collection frame 101 receives the filtered material and is connected to the positioning ring 301 by threads to form a discharge channel. The bottom is equipped with a first motor 201 and a drive shaft 202 to provide power to the crushing blade 402, thereby integrating the functions of discharge and power transmission, simplifying the structure of the device, ensuring smooth material output, and fixing the collection frame 101 to provide overall support for the device, ensuring the stability of the device operation and distributing the load pressure.

[0029] The bottom of the discharge mechanism 1 is provided with a first drive mechanism 2, which includes a first motor 201, a drive shaft 202, and a limiting ring 203. The first motor 201 is fixedly installed in the middle of the bottom of the collection frame 101. The drive shaft 202 is rotatably connected to the bottom of the collection frame 101. The limiting ring 203 is threaded to the outer surface of the drive shaft 202 and is located at the top of the collection frame 101. One end of the drive shaft 202 that passes through the collection frame 101 is rotatably connected to the positioning ring 301 and the middle of the inner wall of the protective shell 401. The first motor 201 serves as the power source for the crushing mechanism 4, driving the drive shaft 202 to rotate, providing a stable speed for the crushing blade 402, ensuring crushing efficiency and particle size consistency. The drive shaft 202 passes through the collection frame 101, the positioning ring 301, and the protective shell 401, and drives the crushing blade 402 to rotate through the positioning groove 403, realizing centralized power transmission, simplifying the transmission structure, and improving system reliability.

[0030] Multiple crushing mechanisms 4 are stacked and installed on top of each other with multiple filtering mechanisms 3.

[0031] The filtration mechanism 3 includes a positioning ring 301 and a filter screen 302. The filter screen 302 is fixedly installed on the inner wall of the positioning ring 301. The positioning ring 301 serves as the main frame of the filtration mechanism 3, providing installation support for the filter screen 302. It is also connected to the protective shell 401 through a threaded structure, realizing the stacked assembly of the crushing mechanism 4 and the filtration mechanism 3. It is connected to the collection rack 101 through the bottom thread to form a discharge channel, ensuring the stable installation of the filter screen 302 and forming a modular connection node. This facilitates the adjustment of the mesh size of the filter screen 302 to adapt to different particle size requirements, realizing the graded filtration function. The filter screen 302 performs particle size screening on the crushed bentonite, intercepting oversized particles and allowing qualified powder to pass through. In conjunction with the multi-layer crushing mechanism 4, it forms a gradient screening system to ensure the uniformity of the final output particle size and prevent unqualified materials from entering subsequent processes.

[0032] The crushing mechanism 4 includes a protective shell 401 and crushing blades 402. The protective shell 401 is threadedly connected to the outer wall of the positioning ring 301. Multiple crushing blades 402 are rotatably connected to the inner wall of the protective shell 401. The crushing mechanism 4 also includes positioning grooves 403, which are respectively formed on the top of multiple crushing blades 402. The inner wall of the positioning groove 403 is connected to the outer surface of the drive shaft 202. The protective shell 401 encloses the crushing space, protecting the internal crushing blades 402 from external interference. At the same time, the threaded connection with the positioning ring 301 enables modular stacking and maintains... The crushing environment is stable, preventing material splashing. It works in conjunction with the filter mechanism 3 to form a multi-stage crushing unit. The crushing blades 402 rotate at high speed driven by the drive shaft 202 to crush the ground material a second time. Through impact and shearing, large pieces of material are refined, and the particle size of the material is reduced in stages. With the help of the filter screen 302, precise particle size control is achieved, improving crushing efficiency and uniformity. The positioning groove 403 is connected to the drive shaft 202 to transmit torque to drive the crushing blades 402 to rotate, ensuring that the crushing blades 402 rotate synchronously, improving crushing stability and avoiding uneven crushing caused by power transmission failure.

[0033] The grinding mechanism 5 includes a concave mold 501, a perforated plate 503, and a punch 504. The concave mold 501 is disposed on the top of the protective shell 401, the perforated plate 503 is fixedly installed in the middle of the bottom of the concave mold 501, and the punch 504 is rotatably connected to the upper part of the inner wall of the concave mold 501. The grinding mechanism 5 also includes multiple diagonal lines 502 and four feed grooves 505. The multiple diagonal lines 502 are respectively opened on the inner wall of the concave mold 501, and the four feed grooves 505 are respectively opened on the punch 504. At the top of 4, the inner wall of the feed trough 505 is connected to the top of the die 501, providing a grinding space. The inner oblique groove 502 structure guides the material to be squeezed towards the punch 504, assisting the grinding process. The top is connected to the feed inlet, and the bottom perforated plate 503 achieves preliminary screening. Through the cooperation of the inclined curved surface and the punch 504, shearing and squeezing action is applied to the material to achieve coarse-grain grinding. The preliminarily qualified material enters the next stage. Installed at the bottom of the concave mold 501, it serves as a material screening channel after preliminary grinding, allowing only particles that meet the initial particle size requirements to pass through, preventing large particles from entering the crushing mechanism 4 and damaging the crushing blades 402. At the same time, it achieves material pre-classification, improving the overall grinding efficiency. The punch 504 rotates inside the concave mold 501 under the drive of the second motor 602, forming a grinding working surface with the oblique grooves 502 of the concave mold 501, and performs rotary grinding on the material. Through mechanical friction and extrusion, the blocky material is broken into smaller pieces, providing basic particle size raw materials for subsequent crushing processes. The oblique grooves 502 are opened on the inner wall of the concave mold 501, guiding the material to move towards the punch 504, enhancing the shearing force during the grinding process, optimizing the material flow path, improving grinding efficiency, and ensuring that the material fully contacts the grinding working surface. The feed trough 505 serves as the material inlet, connecting the external feeding system and the grinding chamber, which can evenly distribute the material to the grinding area, avoid local overload, and ensure the continuity of the grinding process.

[0034] A second drive mechanism 6 is provided on the outer surface of the die 501. The second drive mechanism 6 includes a support frame 601 and a second motor 602. The support frame 601 is bolted to the top of the die 501. The second motor 602 is fixedly installed on the top of the support frame 601. The output end of the second motor 602 is connected to the top of the punch 504 via a key drive. The second motor 602 drives the punch 504 to rotate, providing grinding power. It works with the die 501 to achieve preliminary grinding of the material, laying the foundation for overall crushing. The support frame 601 fixes the second motor 602, supports the top structure of the grinding mechanism 5, ensures the rotation accuracy of the punch 504, and avoids the grinding effect being affected by vibration.

[0035] In summary, the operating steps of this sodium-based bentonite grinding device are as follows:

[0036] 1. Feeding: Sodium-based bentonite is fed into the concave mold 501 of the grinding mechanism 5 through the feed trough 505. The feed trough 505 distributes the material evenly to avoid local overload and ensure the continuity of the grinding process.

[0037] 2. Preliminary grinding: Start the second motor 602 to drive the punch 504 to rotate inside the die 501. The oblique grooves 502 on the inner side of the die 501 guide the material to be squeezed towards the punch 504. The punch 504 and the die 501 cooperate through the inclined curved surface to apply shearing and squeezing action to the material, grinding the blocky material into smaller pieces. The pieces that meet the particle size requirements of the mesh plate 503 at the bottom of the die 501 fall through the mesh plate 503.

[0038] 3. Secondary crushing: The material after preliminary grinding falls into the crushing mechanism 4. At this time, the first motor 201 is started, which drives the drive shaft 202 to rotate. The positioning groove 403 drives the crushing blade 402 to rotate at high speed. The crushing blade 402 impacts and shears the material, further refining the material.

[0039] 4. Grading and screening: During the crushing process, the material is screened by the filter screen 302 to retain oversized particles. Qualified powder continues to the next crushing mechanism 4 or enters the discharge mechanism 1 through the filter screen 302. Gradual screening of materials can be achieved by adjusting the mesh size of the filter screen 302 in the multi-layer filter mechanism 3 to ensure the uniformity of the output particle size.

[0040] 5. Discharge: After multiple crushing and screening, the qualified bentonite powder falls into the collection rack 101, is guided by the guide rack 103, and is smoothly discharged from the device along a specific path, completing the entire grinding process.

[0041] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
