[0023] In a further preferred embodiment of the present invention, the adjustment assembly includes a fixed frame 15 fixed on the sand mill body 1, a lever 17 rotatably mounted on the fixed frame 15 via a support shaft 16, a hydraulic rod 18 hinged to the sand mill body 1 for adjusting the angle of the lever 17, and a connecting mechanism disposed on the lever 17 and connectable to the cover plate 5, wherein the output rod of the hydraulic rod 18 is hinged to the lever 17.

[0024] In this embodiment, the fixed frame 15, which is fixed on the sand mill body 1, provides stable support for subsequent components, ensuring the overall structural stability. The lever 17 is rotatably mounted on the fixed frame 15 via the support shaft 16, allowing the lever 17 to rotate flexibly and providing a basis for the auxiliary disassembly of the cover plate 5. The hydraulic rod 18 (atos hydraulic cylinder CK40) hinged on the sand mill body 1 plays a key role in adjusting the angle of the lever 17. The movement of the lever 17 is precisely controlled by hydraulic power. Through the connecting mechanism on the lever 17 that can be connected to the cover plate 5, the lever 17 can effectively drive the cover plate 5. These components work together to make it easy to disassemble the cover plate 5 with the help of hydraulic power when cleaning the sand mill, avoiding manual disassembly and handling, greatly improving the convenience and efficiency of operation, and reducing labor intensity.

[0025] In a further preferred embodiment of the present invention, the connecting mechanism includes a connecting rope 14 installed at the bottom of the lever 17, a fixing plate 13 installed on the connecting rope 14, a hanging rope 12 and a hook 11 installed on the hanging rope 12 at the bottom of the fixing plate 13, and a hanging ring 10 at the top of the cover plate 5, wherein the hook 11 is hung on the hanging ring 10.

[0026] In this embodiment, the connecting rope 14 installed at the bottom of the lever 17 serves to connect the lever 17 with subsequent connecting components, making the force transmission smoother. The fixing plate 13 installed on the connecting rope 14 provides a stable installation platform for the subsequent installation of the lifting rope 12. The lifting rope 12 and the hook 11 installed on the lifting rope 12 are set at the bottom of the fixing plate 13. With the help of the hanging ring 10 set at the top of the cover plate 5, the hook 11 can be hung on the hanging ring 10, thereby realizing the effective connection between the lever 17 and the cover plate 5. These components work together to enable the connection to be quickly established through a simple hooking operation when the cover plate 5 is disassembled using the adjustment component. The lifting and displacement of the cover plate 5 can be easily realized by the rotation of the lever 17.

[0027] In a further preferred embodiment of the present invention, the outer wall of the grinding jar 2 is provided with a limiting plate 8 that is engaged with the cover plate 5 to stabilize the cover plate 5. The inner wall of the limiting plate 8 is inlaid with a ball bearing 20 that contacts the cover plate 5 to reduce friction. The cover plate 5 is provided with a connecting plate 7, and the connecting plate 7 is threaded with a fixing bolt 9 that is threadedly connected to the grinding jar 2 to stabilize the cover plate 5.

[0028] In this embodiment, the limiting plate 8, which is set outside the cover plate 5, stabilizes the cover plate 5 and effectively prevents it from shifting. The ball bearings 20 embedded in the inner wall of the limiting plate 8 reduce friction when in contact with the cover plate 5, making the installation and disassembly of the cover plate 5 smoother, reducing wear, and extending the service life of the equipment. The fixing bolts 9, which are threaded on the cover plate 5 and threadedly connected to the grinding jar 2, further enhance the stability of the cover plate 5.

[0029] In a further preferred embodiment of the present invention, a safety rod 19 for closing the opening of the hook 11 to prevent it from falling off is hinged to the hook 11. The hook 11 is made of iron, and the safety rod 19 is provided with a magnet block that can be attracted to the hook 11 to stabilize the angle of the safety rod 19.

[0030] In this embodiment, the safety bar 19, which is hinged to the hook 11, plays a key role in closing the opening of the hook 11. This effectively prevents the hook 11 from accidentally falling off the hanging ring 10 due to shaking, vibration, or other factors during the hoisting of the cover plate 5. This greatly enhances the safety of the hoisting operation and reduces the risk of equipment damage and personnel injury. The hook 11 is designed to be made of iron so that the safety bar 19 can maintain a stable angle after the opening of the hook 11 is closed. It is not easy for it to open on its own due to external force, thus ensuring the reliable realization of the function of the safety bar 19.

[0031] In a further preferred embodiment of the present invention, the grinding jar 2 is provided with a jacket that allows cold water to flow in order to assist in heat dissipation. The grinding jar 2 is provided with an inlet pipe and an outlet pipe, and both the inlet pipe and the outlet pipe are provided with a one-way valve for preventing backflow.

[0032] In this embodiment, by setting a jacket inside the sand mill jar 2 that allows cold water to flow, a highly efficient auxiliary heat dissipation effect is achieved. During the long-term operation of the sand mill, the heat generated by the sand milling of the suspension raw material can be carried away by the cold water in time, effectively reducing the internal temperature of the sand mill jar 2, avoiding the impact of high temperature on the performance of the raw material and the stability of the equipment, and ensuring the production quality of the suspension. The sand mill jar 2 is equipped with an inlet pipe and an outlet pipe, which provide a channel for the circulation of cold water, so that the cooling process can continue. The one-way valves installed on the inlet pipe and the outlet pipe play a role in preventing backflow of water, ensuring that the cold water always flows in the set direction and maintaining the stable operation of the cooling system.

[0033] In a further preferred embodiment of the present invention, the outer wall of the grinding jar 2 is provided with an isolation net for isolating contact to prevent burns, and the fixing plate 13 and the hydraulic rod 18 are respectively located on both sides of the support shaft 16.

[0034] In this embodiment, by setting an isolation net on the outer wall of the grinding tank 2 to prevent burns from contact, the safety of the operator is effectively guaranteed. The fixing plate 13 and the hydraulic rod 18 are respectively set on both sides of the support shaft 16, which plays a role in reasonable layout and optimized mechanical structure, and ensures the stability and reliability of the process of lifting the cover plate 5 through the connecting mechanism.

[0035] In summary, compared with related technologies, this device, through its stable installation structure of the grinding tank 2, convenient cover plate 5 for disassembly and adjustment, reliable connection mechanism, stable cover plate 5 fixing and limiting structure, safe hook 11 anti-fall-off design, efficient heat dissipation jacket, and reasonable safety isolation and mechanical layout structure, achieves the goal of ensuring the quality and safety of suspending agent production while improving the convenience and efficiency of equipment cleaning and maintenance, reducing manual labor intensity, and saving manpower and time costs.
