[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0020] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] like Figures 1-4 As shown, a processing device for a coal mill grinding bowl liner includes at least two sets of air-quenching structures and a grinding bowl liner fixture. The grinding bowl liner fixture includes a cover plate 4, lifting claws 5, a first slider 6, a column 7, a sliding rod 8, a spring 9, a first limiting block 10, and a fixing beam 11. There are at least four lifting claws 5, and they are arranged in pairs facing each other. The lifting claws 5 are located below the cover plate 4. The top of one end of the lifting claw 5 is fixedly connected to the column 7 located above the cover plate 4 through the first slider 6 passing through the cover plate 4. The cover plate 4 has a first sliding groove 16 adapted to the first slider 6. The fixing beam 11 is located between the two columns 7 and is fixedly connected to the cover plate 4. Each column 7 is fixedly connected to a sliding rod 8, and the sliding rod 8 also passes through the fixing beam 11. At the same time, the sliding rod 8 and the fixing beam 11 slide together. A spring 9 is sleeved on the sliding rod 8 between the fixing beam 11 and the column 7. The end of the sliding rod 8 away from the column 7 is fixedly connected to the first limiting block 10.

[0022] Specifically, with at least two sets of air quenching structures and grinding bowl liner clamps, when one set is working, the other set can load and unload materials, thus enabling continuous air quenching and increasing air quenching efficiency. The spring 9 pushes the column 7, which in turn pulls the lifting claw 5. The two sets of lifting claws 5 can clamp and lift the grinding bowl liner, preventing the grinding bowl liner from falling off during the air quenching process.

[0023] Furthermore, it also includes a connecting plate 12, a base 18, a horizontal electric slide 19, a vertical electric slide 20, an electric gripper 21, a clamping plate 22, and a flange 23. The horizontal electric slide 19 is horizontally placed above the two sets of air-quenching structures. The base 18 is set at the bottom of both ends of the horizontal electric slide 19. The output end of the horizontal electric slide 19 is connected to the vertical electric slide 20. The output end of the vertical electric slide 20 is connected to the electric gripper 21. The gripper of the electric gripper 21 is provided with a clamping plate 22, and a flange 23 is fixedly provided at the end of the clamping plate 22 away from the gripper. The connecting plate 12 is fixedly connected between the front and rear columns 7 so that it can be clamped by the clamping plate 22 and lifted by the flange 23.

[0024] Specifically, the horizontal electric slide 19 and the vertical electric slide 20 can drive the electric gripper 21 to move horizontally and vertically, respectively, thereby causing the clamping plate 22 and the flange 23 to move synchronously. The connecting plate 12 is suspended by the flange 23, thereby lifting the connecting plate 12 and making the connecting plate 12 move with the electric gripper 21, which facilitates the movement of the grinding bowl liner clamped by the grinding bowl liner clamp. At the same time, the clamping plate 22 clamps the connecting plate 12, making the connecting plates 12 move closer to each other, thereby driving the column 7 to move horizontally. Then the lifting claw 5 moves horizontally, causing the lifting claw 5 to expand, thereby loosening the grinding bowl liner or making it easier to clamp the grinding bowl liner.

[0025] Furthermore, the air quenching structure includes an air quenching box 1, a blower 2, and an exhaust fan 3. The top of the air quenching box 1 is open and is adapted to the cover plate 4. Two sets of blowers 2 and exhaust fans 3 are arranged opposite to each other on the four sides of the air quenching box 1.

[0026] Specifically, the air supply and exhaust of the blower 2 and the exhaust fan 3 can form convection, allowing the airflow to pass quickly through the air quenching box 1, and then the grinding bowl liner is air quenched.

[0027] Furthermore, a sealing strip 15 is provided at the bottom of the cover plate 4, and the sealing strip 15 is adapted to the top opening of the air quenching box 1 to increase the sealing between the cover plate 4 and the air quenching box 1, so that the airflow can be smoothly sent in and extracted by the blower 2 and the exhaust fan 3.

[0028] Furthermore, the grinding bowl liner clamp also includes a second slider 13 and a second limiting block 14. The second slider 13 is fixedly connected to the middle of the top of the lifting claw 5, and the second slider 13 extends through the top of the cover plate 4. The second limiting block 14 is fixedly connected to the top of the second slider 13. The top of the cover plate 4 is also provided with a second groove 17 adapted to the second slider 13.

[0029] Specifically, the second slider 13 and the second limiting block 14 move with the lifting claw 5, and the second slider 13 and the second limiting block 14 slide on the cover plate 4 during movement, thereby increasing the stability of the lifting claw 5.

[0030] In the above structure, spring 9 can push column 7, causing column 7 to move lifting claws 5 closer together. When electric gripper 21 is activated, clamping plate 22 can clamp connecting plate 12, causing connecting plate 12 to move closer together, thereby pulling column 7 to move horizontally, causing lifting claws 5 to move away from each other, thus facilitating clamping or releasing of grinding bowl liner. Horizontal electric slide 19 and vertical electric slide 20 can respectively drive electric gripper 21 to move horizontally and vertically, thereby causing clamping plate 22 and flange 23 to move synchronously. Flanging plate 23 can lift connecting plate 12, causing connecting plate 12 to move with electric gripper 21, thus facilitating the movement of grinding bowl liner. After grinding bowl liner is moved into air quenching box 1, blower 2 and exhaust fan 3 are activated to generate airflow for air quenching of grinding bowl liner. The efficiency of air quenching can be increased through the two sets of air quenching components.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed. The scope of protection of this application is defined by the appended claims and their equivalents.
