[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] Example 1

[0025] like Figures 1-4 As shown, a grinding slurry stirring device includes a vessel body 1 for containing grinding slurry and solid raw materials. A vessel cover 2 is installed on the vessel body 1 for sealing the vessel body 1. A stirring motor 3 is installed at the center of one end of the vessel cover 2, which is the driving source of this stirring device. One end of the stirring motor 3 is connected to a first rotating rod 4 that rotates through the interior of the vessel body 1 for transmitting the power of the stirring motor 3. Multiple sets of first stirring blades 5 are installed at one end of the first rotating rod 4 in the vessel body 1 for stirring the grinding slurry and solid raw materials.

[0026] The material distribution and filtration assembly is located at one end of the vessel cover 2 and is used in conjunction with the vessel body 1.

[0027] Example 2

[0028] like Figures 1-4 As shown, the material distribution and filtration assembly includes a material distribution straight pipe 8, which is mounted around the vessel cover 2. One end of the material distribution straight pipe 8 is rotatably connected to a diversion bend 6. Multiple diversion bends 6 are provided, and one end of each diversion bend 6 is connected to a feed hopper 7. The feed hopper 7 is used to feed solid particles. At the same time, a discharge channel for feeding liquid raw materials is provided on one side of the vessel body 1. The end of the material distribution straight pipe 8 away from the diversion bend 6 passes through the vessel cover 2 and is connected to a filter screen cylinder 9. A baffle 24 is installed at the end of the filter screen cylinder 9 away from the material distribution straight pipe 8. A transmission gear 10 is installed at the end of the first rotating rod 4 away from the vessel body 1. A first driven gear 11 that meshes with the transmission gear 10 is installed at the end of the material distribution straight pipe 8 close to the diversion bend 6.

[0029] like Figures 1-4 As shown, the material distribution and filtration assembly also includes a connecting frame 12 and a second rotating rod 14. The connecting frame 12 is installed inside the end of the material distribution straight pipe 8 near the diversion bend 6. A crushing rod 13 is fixedly connected to the middle of the connecting frame 12. The second rotating rod 14 is installed around and rotates through the edge of the vessel cover 2. A second driven gear 16 that meshes with the first driven gear 11 is installed at the end of the second rotating rod 14 away from the vessel body 1. Multiple sets of second stirring blades 15 are installed at the end of the second rotating rod 14 away from the second driven gear 16.

[0030] During operation, liquid raw materials are fed through the feeding channel, and solid raw materials are fed through the feeding hopper 7. The solid raw materials enter the multi-component straight pipe 8 through the multi-component flow bend pipe 6 and fall into the multi-component filter cylinder 9. This achieves the effect of feeding solid raw materials into multiple points inside the vessel body 1, avoiding local accumulation of solid raw materials in a certain area of ​​the vessel body 1, and thus achieving uniform distribution of solid raw materials. At the same time, the stirring motor 3 is started, which drives the multi-component first stirring blades 5 to rotate through the first rotating rod 4, mixing and stirring the solid and liquid raw materials inside the vessel body 1.

[0031] Simultaneously, when the first rotating rod 4 rotates, it drives multiple sets of first driven gears 11 to rotate through the meshing of the transmission gear 10. This, in turn, drives multiple sets of filter cylinders 9 to rotate through the material distribution straight pipe 8, thereby increasing the contact area between the solid and liquid raw materials placed inside the filter cylinder 9. This improves the stirring efficiency and intercepts large solid raw materials through the filter holes of the filter cylinder 9, reducing their entry into the stirring area and achieving a preliminary filtration effect on the grinding liquid.

[0032] At the same time, when the distribution pipe 8 rotates, the crushing rod 13 is driven to rotate through the connecting frame 12, which crushes the solid raw materials entering the vessel body 1, reduces the blockage of solid raw materials in the distribution pipe 8, and reduces the size of raw material particles, making them easier to mix with liquid raw materials and improving stirring efficiency.

[0033] At the same time, when the first driven gear 11 rotates, it meshes with and drives the second driven gear 16 to rotate, so that multiple sets of second rotating rods 14 drive multiple sets of second stirring blades 15 to rotate, thereby forming multiple stirring zones in the vessel body 1, effectively dispersing the liquid flow, avoiding the vortex phenomenon caused by a single first stirring blade 5, and thus improving the uniformity and stability of stirring.

[0034] Example 3

[0035] like Figures 1-4 As shown, a mounting bracket 18 is fixedly connected to the outer wall of the filter screen cylinder 9 near the material distribution straight pipe 8. A mounting clamp 19 is fixedly connected to one end of the mounting bracket 18. The inner wall of the mounting clamp 19 is sleeved with the outer wall of one end of the material distribution straight pipe 8. A cross screw 20 is provided at the connection between the mounting clamp 19 and the material distribution straight pipe 8.

[0036] like Figures 1-4 As shown, a sealing ring 17 is provided at the connection between the vessel body 1 and the vessel cover 2. An electric push rod 21 is installed around the outer wall of the vessel body 1. A connecting block 22 is connected to the moving end of the electric push rod 21. One end of the connecting block 22 is connected to the vessel cover 2.

[0037] like Figures 1-4 As shown, an observation window 23 is provided on one side of the vessel body 1 to facilitate personnel to observe the stirring of the liquid inside the vessel body 1 at any time.

[0038] During operation, when maintenance is required on the vessel body 1 and the filter cylinder 9, the vessel cover 2 is moved away from the vessel body 1 by pushing the moving end of the electric push rod 21. This will cause the filter cylinder 9 and the corresponding stirring component to extend out of the vessel body 1 for subsequent maintenance. At the same time, when the filter cylinder 9 needs to be replaced, the mounting clamp 19 can be quickly separated from the distribution straight pipe 8 by loosening the cross screw 20 with a screwdriver, so that the filter cylinder 9 can be removed from the distribution straight pipe 8, thus facilitating the subsequent replacement of the filter cylinder 9.

[0039] The operation of the grinding slurry stirring device provided by this utility model is as follows: Liquid raw materials are fed through the feeding channel, and solid raw materials are fed through the feeding hopper 7. The solid raw materials enter the multi-component distribution straight pipe 8 through the multi-component flow bend pipe 6 and fall into the multi-component filter cylinder 9, so as to achieve the effect of distributing solid raw materials into multiple points inside the vessel body 1, avoiding local accumulation of solid raw materials in a certain area of ​​the vessel body 1, thereby achieving uniform distribution of solid raw materials. At the same time, the stirring motor 3 is started, which drives the multi-component first stirring blades 5 to rotate through the first rotating rod 4, mixing and stirring the solid and liquid raw materials inside the vessel body 1. When the first rotating rod 4 rotates, it drives the multi-component first driven gears 11 to rotate through the transmission gear 10, which in turn drives the multi-component filter cylinder 9 to rotate through the distribution straight pipe 8, thereby increasing the amount of solid raw materials distributed inside the filter cylinder 9. The contact area between solid and liquid raw materials is increased, thereby improving stirring efficiency. Large solid raw materials are intercepted through the filter holes of the filter cylinder 9 to reduce their entry into the stirring area, achieving a preliminary filtration effect on the grinding liquid. At the same time, when the distribution straight pipe 8 rotates, the connecting frame 12 drives the crushing rod 13 to rotate, crushing the solid raw materials entering the reactor body 1, reducing the blockage of solid raw materials in the distribution straight pipe 8, and reducing the size of raw material particles, making them easier to mix with liquid raw materials and improving stirring efficiency. Meanwhile, when the first driven gear 11 rotates, it meshes and drives the second driven gear 16 to rotate, causing multiple sets of second rotating rods 14 to drive multiple sets of second stirring blades 15 to rotate, forming multiple stirring areas in the reactor body 1, effectively dispersing the liquid flow, avoiding the vortex phenomenon caused by a single first stirring blade 5, thereby improving the uniformity and stability of stirring.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
