Technical Field

[0001] This utility model relates to the field of ceramic plate raw material grinding, and specifically to a ceramic plate processing raw material grinding device. Background Technology

[0002] Grinding the raw materials used to make ceramic slabs is to refine and evenly distribute the raw material particles, thereby improving the reactivity, molding performance, and sintering quality of the raw materials. This ensures that the ceramic slabs have a uniform and dense structure with excellent mechanical and thermal properties. Modern ceramic raw material grinding equipment, through efficient and precise grinding processes, not only improves the utilization rate of raw materials and production efficiency, but also reduces impurities and defects, laying a solid foundation for subsequent molding and sintering processes.

[0003] In existing ceramic processing raw material grinding devices, various coarse and fine powders are mixed together when grinding ceramic raw materials. The ground powder needs to be screened a second time to obtain powders of different fineness for reuse. The lack of effective screening of the ground powder during the first grinding process affects the uniformity of the raw materials and the grinding efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing a ceramic plate processing raw material grinding device, thereby solving the aforementioned technical problems.

[0005] This utility model provides a grinding device for ceramic plate processing raw materials, including a grinding box body and a feed inlet disposed on the top of the grinding box body, and further including:

[0006] Multi-stage grinding components are installed inside the grinding box. The multi-stage grinding components will crush the raw materials fed from the feed inlet in stages.

[0007] A screen assembly is located inside the grinding chamber and below the multi-stage grinding assembly. A drive assembly is located below the screen assembly, which drives the screen assembly to screen the raw materials that have been crushed by the multi-stage grinding assembly.

[0008] The discharge component is located on the side wall of the grinding box body and corresponds to the position of the screen assembly. The discharge component is used to discharge the processed raw materials that have not passed through the screen assembly from the grinding box body.

[0009] Preferably, the multi-stage grinding assembly includes two sets of meshing grinding rollers, which are rotatably connected to the grinding box body. The two sets of grinding rollers are arranged vertically along the inner wall of the grinding box body. Several grinding teeth are arranged in an array on the grinding rollers, wherein the grinding teeth on the lower set of grinding rollers are denser than those on the upper set of grinding rollers.

[0010] Preferably, a drive shaft is fixedly installed through the center of the crushing roller, and the drive shaft is rotatably connected to the opposite side wall of the grinding box body. A first motor is installed on the outer side wall of the grinding box body, and one end of the drive shaft passes through the side wall of the grinding box body and is fixedly connected to the output shaft of the first motor.

[0011] Preferably, the screen assembly includes a screening screen, and grooves are provided on the opposite side walls of the grinding box body. The two ends of the screening screen are slidably connected to the grooves, and two abutment parts are fixedly installed at the bottom of the screening screen.

[0012] Preferably, the drive assembly includes two rotating shafts, which are rotatably connected to the side walls opposite to the grinding chamber body.

[0015] Compared with existing technologies, it has the following beneficial effects:

[0016] This invention provides a grinding device for ceramic slab processing raw materials. Through a multi-stage grinding assembly, the raw materials are progressively pulverized, refining them step by step. This solves the problem of uneven particle size in traditional grinding devices, resulting in finer and more uniformly distributed particles, thus improving grinding efficiency and raw material quality. A drive assembly is installed below the screen assembly to drive the screen and separate the ground raw materials, solving the problem of mixing coarse and fine particles. This ensures that only fine particles that meet the requirements pass through the screen, while coarse particles are intercepted, further improving the uniformity of the raw materials. The discharge component can promptly discharge coarse particles that do not pass through the screen from the grinding chamber and reintroduce them into the grinding device for further grinding, improving production efficiency. Through the above methods, efficient and uniform grinding of raw materials is achieved, resulting in ceramic processing raw materials with uniform texture, ultimately improving the quality of ceramic slabs and increasing production efficiency.

[0022] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0023] Example 1:

[0024] like Figures 1 to 3 As shown, this utility model provides a grinding device for ceramic plate processing raw materials, including a grinding box body 1 and a feed inlet 2 disposed on the top of the grinding box body 1, and further including:

[0025] A multi-stage grinding assembly is installed inside the grinding box body 1. The multi-stage grinding assembly will crush the raw materials fed from the feed inlet 2 in stages.

[0026] A screen assembly is disposed inside the grinding box body 1 and below the multi-stage grinding assembly. A drive assembly is disposed below the screen assembly, and the drive assembly drives the screen assembly to screen the raw materials after they have been crushed by the multi-stage grinding assembly.

[0027] The discharge component is located on the side wall of the grinding box body 1 and corresponds to the position of the screen assembly. The discharge component is used to discharge the processed raw materials that have not passed through the screen assembly from the grinding box body 1.

[0028] During use, the raw material is fed into the multi-stage grinding component inside the grinding box through the inlet 2 at the top. The raw material is ground into finer and more uniform particles step by step through a process of gradual crushing. The ground raw material falls onto the screen component below, which vibrates continuously under the action of the drive component to screen the raw material. Fine particles pass through the screen and enter the next process, while coarse particles are intercepted, ensuring the uniformity of the raw material. Coarse particles that do not pass through the screen are discharged from the grinding box in time by the discharge component on the side wall. After collection, they are put back into the grinding device for a second grinding, ensuring that the final processed raw material has a uniform texture.

[0029] Example 2:

[0030] like Figures 1 to 3 As shown, in conjunction with the technical solution of Embodiment 1, in this technical solution, the multi-stage grinding assembly includes two sets of intermeshing grinding rollers 3. The grinding rollers 3 are rotatably connected to the grinding box body 1. The two sets of grinding rollers 3 are arranged vertically along the inner wall of the grinding box body 1. Several grinding teeth 4 are arranged in an array on the grinding rollers 3, wherein the grinding teeth 4 on the lower set of grinding rollers 3 are denser than those on the upper set of grinding rollers 3. After the raw material is fed from the top, it is first subjected to preliminary grinding by the upper set of grinding rollers 3, and the particles are ground to a smaller size. Then it falls onto the lower set of grinding rollers 3. Because the grinding teeth 4 of the lower set of grinding rollers 3 are denser, the raw material is further ground to a finer and more uniform size.

[0031] Furthermore, a drive shaft 5 is fixedly installed through the axis of the crushing roller 3. The drive shaft 5 is rotatably connected to the opposite side wall of the grinding box body 1. A first motor is installed on the outer side wall of the grinding box body 1. One end of the drive shaft 5 passes through the side wall of the grinding box body 1 and is fixedly connected to the output shaft of the first motor. The drive shaft 5 drives the crushing roller 3 to rotate at high speed, and the grinding teeth 4 on the crushing roller 3 crush the raw materials.

[0032] Furthermore, the screen assembly includes a screening screen 6, and grooves 7 are formed on the opposite side walls of the grinding box body 1. The two ends of the screening screen 6 are slidably connected to the grooves 7, and two abutment parts 8 are fixedly installed at the bottom of the screening screen 6. When the ground raw material falls onto the screening screen 6, the screening screen 6 begins to vibrate under the action of the drive component. Fine particles pass through the screen and fall into the collection box below, while coarse particles are intercepted on the screening screen 6.

[0033] Furthermore, the drive assembly includes two rotating shafts 9, which are rotatably connected to the side walls of the grinding chamber body 1. One end of each rotating shaft 9 passes through the side wall of the grinding chamber body 1. A second motor is mounted on the outer side wall of the grinding chamber body 1, and the output shaft of the second motor is fixedly connected to the rotating shafts 9. The two rotating shafts 9 are located below the screening screen 6, and cams 10 are fixedly mounted on the two rotating shafts 9. The cams 10 abut against the contact portion 8 at the bottom of the screening screen 6. When the rotating shafts 9 rotate, the cams 10 continuously push the contact portion 8 of the screening screen 6, causing the screening screen 6 to vibrate up and down. This vibration allows the raw material falling on the screening screen 6 to be efficiently screened, with fine particles passing through the screen and falling below, while coarse particles are intercepted.

[0034] Furthermore, the discharge component includes a discharge plate 11. A discharge port for accommodating the discharge plate 11 is provided on the side wall of the grinding box body 1. The bottom of the discharge plate 11 is hinged to the discharge port. A locking buckle 12 is rotatably installed on the outer side wall of the grinding box body 1. The locking buckle 12 is used to open or close the discharge port. When coarse particles that have not passed through the screen accumulate to a certain extent after screening, the discharge plate 11 can be opened by operating the locking buckle 12, and the coarse particles will be discharged from the discharge port and enter the second box 14 below. After the discharge is completed, the discharge plate 11 is closed and fixed with the locking buckle 12, and the normal grinding and screening process continues.

[0035] Furthermore, a first housing 13 is provided below the screen assembly to collect the processed raw materials after screening, and a second housing 14 is provided below the discharge port to collect the processed raw materials that have not passed through the screening screen 6. The first housing 13 below the screen assembly collects the fine particles that have passed through the screening screen 6, which can be directly used for subsequent processing. The second housing 14 below the discharge port collects the coarse particles that have not passed through the screening screen 6. After the screening process is completed, the fine particles will naturally fall into the first housing 13, while the coarse particles will be discharged through the discharge port and enter the second housing 14.

[0036] The working principle of a ceramic plate processing raw material grinding device disclosed in this application is as follows:

[0037] In use, the raw material is fed into the inlet 2 at the top of the grinding box and first enters the multi-stage grinding assembly. This assembly consists of two sets of crushing rollers 3 with grinding teeth 4. The two sets of crushing rollers 3 mesh with each other, and the raw material is ground finer and finer under the step-by-step crushing of the two sets of crushing rollers 3. The ground raw material falls onto the screen assembly below. The screen assembly is driven to vibrate by the cam 10 and the rotating shaft 9 in the drive assembly to screen the raw material. Fine particles fall through the screen into the first box 13 below, while coarse particles are intercepted. Coarse particles that do not pass through the screen are discharged by the discharge component on the side wall and discharged into the second box 14. This avoids the problem of uneven texture of the ground raw material caused by coarse particles falling into the first box 13. The whole process achieves uniform grinding and screening of raw materials through the combination of multi-stage grinding, vibrating screening and discharge, thus improving the quality of ceramic plates.

[0038] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
