Description

Technical Field

[0001] The utility model relates to the technical field of mining and processing equipment, and more specifically to a grinding device for kaolin processing. Background Art

[0002] Kaolin is a non-metallic mineral, a kind of clay and clay rock mainly composed of kaolinite group clay minerals. Kaolin is white, delicate, and soft in texture. It needs to be processed through processes such as crushing, filtering, and grinding before it can be stored as a finished product. Kaolin belongs to ore soil and has a certain amount of dust. Therefore, grinding needs to be carried out in a closed cavity. Otherwise, it is easy to cause dust to fly, which is inhaled by workers, affecting their health and polluting the environment, not meeting the environmental protection requirements. At the same time, kaolin grinding needs to be filtered through a filter screen. Otherwise, the particle sizes of kaolin are uneven, affecting the grinding quality. In existing grinding processes, grinding and filtering are usually carried out separately. In this way, the processing efficiency is greatly affected and the labor intensity of workers is increased. In response to this, the inventor has proposed a grinding device for kaolin processing to solve this problem. By integrating the grinding device and the filtering device, kaolin grinding and filtering are realized, and at the same time, it also has a dust-proof function.

[0003] In order to improve the grinding quality and efficiency of kaolin, Chinese Patent (Authorization Publication No.: CN218531135U) discloses a kaolin grinder. The utility model includes a housing and a feed pipe passing through the top of the housing. A filter screen is arranged inside the housing. A rotating rod is arranged in the upper half of the housing. The rotating rod rotates through the filter screen. A driving part is arranged at the top of the housing. The driving part drives the rotating rod to rotate. A plurality of powder-breaking pieces are fixedly arranged on the outer peripheral surface of the rotating rod between the inner top wall of the housing and the filter screen. The bottom end of the rotating rod is fixedly connected with a grinding block. The lower half of the grinding block is arc-shaped, and a plurality of convex blocks are formed at the bottom of the grinding block. A grinding plate is fixedly connected inside the housing. After being crushed, the kaolin moves through the filter screen to the periphery of the grinding block, and the grinding block rotates to grind the kaolin, which is convenient for grinding large pieces of kaolin and greatly improves the grinding efficiency.

[0004] There are still some deficiencies in the application of this solution. After kaolin is ground, the particle sizes of kaolin particles are uneven and need to be filtered. Otherwise, the discharge quality will be affected. At the same time, dust-proof settings are required during grinding and filtering to avoid dust flying and causing environmental pollution. Therefore, it is necessary to improve the structure of the grinder so that it not only has a grinding function but also has a filtering function, realizes an integrated design of grinding and filtering, and at the same time has a dust-proof function, increasing the practicality of the grinder.

[0019] The following further illustrates the specific embodiments of the present utility model with reference to the accompanying drawings

[0020] As Figures 1 to 4 shown, a grinding device for kaolin processing includes a grinding tank body 1, a filter screen 2 and a dust-proof cover 3. The upper side wall of the grinding tank body 1 is provided with a cylindrical groove body 11, and cylinders 12 are provided on the left and right sides. The lower part of the dust-proof cover 3 is embedded in the cylindrical groove body 11 and can move up and down along the cylindrical groove body 11 through the cylinders 12. A motor 4 is provided in the middle of the top of the dust-proof cover 3. A grinding roller 5 is installed on the motor 4. The grinding roller 5 is placed inside the grinding tank body 1. A grinding part 6 is provided at the bottom of the grinding roller 5. The filter screen 2 is detachably arranged in the middle and lower part of the grinding tank body 1. Oscillators 7 are installed on both sides of the filter screen 2

[0021] Furthermore, the lower part of the grinding tank body 1 is in a funnel structure and an outlet 8 is provided in the middle. The outlet 8 is provided with an opening and closing valve

[0022] Furthermore, a feeding port 9 is provided on one side of the upper part of the grinding tank body 1

[0023] Furthermore, the dust-proof cover 3 includes a trapezoidal part 31 at the upper part and an embedding part 32 at the lower part. A limiting block 33 is provided between the trapezoidal part 31 and the embedding part 32. The limiting block 33 is movably arranged on the top of the grinding tank body 1

[0024] Furthermore, a grinding spiral structure 51 is provided on the side wall of the grinding roller 5, and grinding blades 52 are provided on the outside of the grinding spiral structure 51

[0025] Furthermore, the filter screen 2 is in a "rice" - shaped structure and a grinding groove 10 is provided at the top. The grinding part 6 is movably embedded in the grinding groove 10

[0026] [Embodiment]

[0027] First, kaolin enters the grinding tank body 1 from the feeding port 9. The motor 4 is started, and the kaolin is ground by the grinding member 6 at the bottom of the grinding roller 5 and the grinding spiral structure 51 on the side wall. At this time, the grinding member 51 is embedded in the grinding groove 10. Some kaolin directly falls into the funnel structure through the filter screen 2 after grinding. However, most of the kaolin particles accumulate on the filter screen 2 and cannot fall. Then, the dust-proof cover 3 is lifted upward by the air cylinder 12, so that the grinding member 6 leaves the grinding groove 10. The embedded part 32 of the dust-proof cover 3 is still embedded in the cylindrical groove body 11 to prevent dust from drifting outwards. The oscillator 7 is started to vibrate the filter screen 2 to filter the ground kaolin. The filtered kaolin falls into the funnel structure. Finally, the air cylinder 12 is retracted, and the kaolin is ground for the second time by the grinding member 6 and the grinding spiral structure 51. New kaolin can be added according to the situation during the grinding process to achieve the grinding and filtering of kaolin, and the filtering effect is good.

[0028] As can be seen from the above description of the present invention, compared with the prior art, the advantages of the present invention are as follows:

[0029] The present invention first sets a dust-proof cover above the grinding tank body, and then sets a motor and a grinding roller on the top of the dust-proof cover to perform sealed grinding on kaolin to prevent dust from drifting and polluting the environment. Then, by setting a grinding member at the bottom of the grinding roller and a grinding spiral structure on the side wall, an effective grinding function can be achieved. At the same time, blades are provided on the outside of the grinding spiral structure to further improve the grinding effect. Finally, a filter screen is provided in the middle and lower part of the grinding tank body. The filter screen is provided with an oscillator. At the same time, the dust-proof cover and the grinding member can be lifted upward by the air cylinder. Lifting the grinding member upward facilitates the vibration of the filter screen for filtering. The dust-proof cover is lifted upward, but the embedded part is still embedded in the cylindrical groove body, which can maintain the sealed state of the grinding tank body. The structure of the present invention is novel, the design is ingenious, the practicability is strong, and it is suitable for popularization.

[0030] The above is only the specific implementation manner of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantive improvement made to the present invention using this concept should belong to the act of infringing the protection scope of the present invention.
