[0001] The utility model relates to the field of grinding equipment, in particular to a ceramic-based mixed grinding device. Background Art

[0002] Ceramic-matrix composites (CMCs) are a type of composite material composed of a ceramic matrix and various fibers. By combining high-strength, highly elastic fibers with a brittle ceramic matrix, the toughness and reliability of the ceramic can be enhanced while retaining the material's excellent properties, such as high-temperature resistance, high strength and stiffness, relatively low weight, and corrosion resistance. The fibers inhibit crack propagation, resulting in fiber-reinforced CMCs with excellent toughness. Currently, CMCs are used in liquid rocket engine nozzles, missile radomes, space shuttle nose cones, aircraft brake discs, and high-end automobile brake discs, making them a key branch of high-tech new materials.

[0003] In the processing of ceramic-based materials, it is often necessary to mix and grind the composite materials to ensure the uniformity of the mixing of the materials.

[0023] Referring to Figure 2 and Figure 3 , the rotating rod one 12 and the rotating rod two 22 are detachably fixedly connected with the grinding pieces 13 by bolts, so that the damaged grinding pieces 13 can be replaced at any time when needed, the grinding quality is ensured, and compared with replacing the rotating rod one 12 and the rotating rod two 22, the operation is simple, efficient and convenient.

[0024] Referring to Figure 2 , the air pressure pump 18 is fixedly connected with the bottom of the base box 1 by bolts, the air pressure pump 18 is sealingly connected with the air guide pipe 19, and the air guide pipe 19 is detachably sealingly connected with the air injection valve 20 by a flange plate, so that the stability of the air pressure pump 18 during work is ensured, air is drawn into and pressurized by the air pressure pump 18, guided through the air guide pipe 19, and finally sprayed out by the air injection valve 20, to form turbulent airflow in the mixed grinding cylinder 9, so that the material is repeatedly ground and mixed between the rotating rod one 12 and the rotating rod two 22, to realize "ruminant type" mixed grinding processing.

[0025] Referring to Figure 2 , the operating box 2 is electrically connected with the vibrator 15, and the operating box 2 is electrically connected with the air pressure pump 18, so that the working personnel can input the working parameters from the operating box 2 to set the working parameters of the vibrator 15 and the air pressure pump 18.

[0026] Referring to Figure 1 and Figure 2 , the breathable dustproof cover 23 is screwed on the top of the blanking cylinder 11, so that the air sprayed out by the air injection valve 20 can be dissipated through the breathable dustproof cover 23, to balance the air pressure inside and outside the device.

[0027] Referring to Figure 1 Each sealed chamber 17 is in communication with air through an air inlet grille 4, which is arranged to facilitate the air pressure pump 18 to directly draw in external air through the air inlet grille 4 and pressurize when working.

[0030] Working principle: when using the device, the material to be ground is injected into the mixing and grinding cylinder 9 through the feeding cylinder 11, and then the operation box 2 inputs the working instruction, starts the motor 5, and outputs power through the motor 5. The motor 5 drives the driving gear shaft 8 to rotate through the transmission chain 7, and the driving gear shaft 8 drives the driven gear shaft 21 and the rotating rod two 22 to rotate. The rotating rod one 12 is driven by the driven gear shaft 21 to rotate, and the material is mixed and ground by the grinding pieces 13 installed on the rotating rod one 12 and the rotating rod two 22 through the relative rotation of the rotating rod one 12 and the rotating rod two 22. At the same time, the air pressure pump 18 can draw in air and pressurize to generate high-pressure and high-speed airflow. After the airflow passes through the air guide pipe 19 and the air injection valve 20, it is sprayed out to form chaotic airflow in the mixing and grinding cylinder 9. The airflow pushes the material to repeatedly grind and mix between the rotating rod one 12 and the rotating rod two 22 until the diameter of the material reaches the qualified size. The ground qualified material is filtered through the filter screen plate 14 and then enters the material box 16 for centralized recovery and treatment.
