[0001] The utility model relates to quartz powder production technical field, especially a ball mill lining plate and ball mill for quartz powder production. BACKGROUND

[0002] In the production of quartz powder, the ball mill drives the quartzite and grinding body in its cylinder to repeatedly tumble to break the quartzite into smaller particles for further production. In the structure of the ball mill, a plurality of ball mill lining plates are arranged in a spliced form on the inner wall of the cylinder of the ball mill. The ball mill lining plate drives the grinding body and the quartzite to run to a certain height and then falls. The breakage of the quartzite is achieved through the impact of the grinding body on the quartzite and the impact of the quartzite on the lining plate of the ball mill. In the prior art, in order to reduce the vibration when the grinding body and the quartzite and other materials impact the lining plate, for example, the utility model patent: ball mill lining plate with buffering and damping functions (publication number: CN216826500U) discloses a ball mill lining plate that can reduce vibration amplitude and effectively reduce noise. However, in the above ball mill lining plate, since the ball mill lining plate moves along one direction with the ball mill cylinder, the impact of the grinding body and the quartzite will cause local wear of the ball mill lining plate, shorten the service life of the ball mill lining plate, increase the frequency of replacing the ball mill lining plate, and affect the production efficiency.

DETAILED DESCRIPTION

[0025] The following will combine the drawings in the embodiments of the present application to make a further description. Figures 1-9In order to make the technical solutions in the embodiments of the present application clear and complete, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] As shown in the figure, a ball mill lining plate for quartz powder production, including base plate 1 and semicircle ball wear-resistant block 2, the base plate 1 is provided with several installation cavities 11 matched with wear-resistant block 2, the wear-resistant block 2 bottom is fixedly connected with support column 3, the installation cavity 11 bottom is provided with sliding cavity 13 matched with support column 3, the sliding cavity 13 side wall is provided with limiting ring groove 12, the sliding cavity 13 bottom is provided with buffer pad layer 4, the wear-resistant block 2 is placed in installation cavity 11 so that support column 3 penetrates into sliding cavity 13, the support column 3 side wall is provided with limiting rod 5 penetrating into limiting ring groove 12, the limiting rod 5 outer diameter is less than the height of limiting ring groove 12, the sliding cavity 13 is provided with buffer spring 6 between buffer pad layer 4 and support column 3, the buffer spring 6 both ends are respectively abutted with support column 3 and buffer pad layer 4, the limiting rod 5 is abutted on limiting ring groove 12 inner wall under the action of buffer spring 6, so that the wear-resistant block 2 bottom and installation cavity 11 bottom form buffer gap, and the buffer gap provides space for wear-resistant block 2 axial sliding in installation cavity 11 along support column 3.

[0027] In the above structure, the support column 3 has a tendency to slide outward under the action of the buffer spring 6, and the sliding stroke of the support column 3 outward is limited by the stroke of the limiting rod 5 sliding axially in the limiting ring groove 12 along the support column 3, so that the wear-resistant block 2 and the support column 3 are respectively kept in the mounting cavity 11 and the sliding cavity 13, and the base plate 1 is fixedly connected to the inner wall of the cylinder of the ball mill through the back thereof and is installed on the inner wall of the cylinder of the ball mill, and when the ball mill is working, the tumbling grinding bodies and the quartz stone material collide with the wear-resistant block 2, and generally, the force generated by the collision of the grinding bodies and the material on the wear-resistant block 2 is not completely axial along the support column 3, so that the force acting on the wear-resistant block 2 when colliding is decomposed into the force along the support column 3 axial and the force along the circumference of the support column 3, and since the outer diameter of the limiting rod 5 is smaller than the height of the limiting ring groove 12, the force acting on the wear-resistant block 2 along the support column 3 axial makes the wear-resistant block 2, the support column 3 and the limiting rod 5 respectively slide along the support column 3 axial in the mounting cavity 11, the sliding cavity 13 and the limiting ring groove 12 to compress the buffer spring 6, and after the end of the support column 3 abuts against the buffer pad layer 4, the vibration is absorbed by the buffer pad layer 4, so that the buffer spring 6 and the buffer pad layer 4 cooperate to play a buffering and damping effect on the wear-resistant block 2, reduce the noise when the ball mill is working, and at the same time, the force acting on the wear-resistant block 2 along the circumference of the support column 3 makes the wear-resistant block 2, the support column 3 and the limiting rod 5 respectively rotate along the circumference of the support column 3 in the mounting cavity 11, the sliding cavity 13 and the limiting ring groove 12, so that the wear-resistant block 2 updates the contact surface with the grinding bodies and the material in real time by rotating during the working process of the ball mill, and further makes the wear of the wear-resistant block 2 more uniform, prolongs the service life of the wear-resistant block 2, prolongs the overall service life of the ball mill liner, and thus ensures the production efficiency of the ball mill.

[0028] In addition, on the basis of the above structure, a plurality of longitudinal and transverse intersecting convex teeth 21 are formed on the spherical surface of the wear-resistant block 2, and the material collides with the convex teeth 21 when colliding with the wear-resistant block 2, and the crushing efficiency of the material is improved by the action of the convex teeth 21, thereby improving the working efficiency of the ball mill.

[0029] Further, on the basis of the above structure, the wear-resistant block 2 is centrally provided with a connecting bolt 22 threaded with the support column 3, to realize the fixed connection of the support column 3 and the wear-resistant block 2. Specifically, the support column 3 is formed with a multi-prism-shaped insertion pile 31 at the end, and the wear-resistant block 2 is formed with an insertion hole 23 matched with the insertion pile 31 at the bottom. The insertion pile 31 is inserted into the insertion hole 23, and the connecting bolt 22 is threaded on the insertion pile 31. The wear-resistant block 2 and the support column 3 are connected through the connecting bolt 22, so that the wear-resistant block 2 and the support column 3 can be easily disassembled, thereby facilitating the replacement of the worn wear-resistant block 2, convenient operation and facilitating the control of the use cost of the ball mill. The multi-prism-shaped insertion pile 31 and the insertion hole 23 cooperate to limit the relative rotation of the wear-resistant block 2 and the support column 3 in the circumferential direction of the support column 3, preventing the relative rotation of the wear-resistant block 2 and the support column 3 from loosening the connecting bolt 22, thereby enhancing the stability of the fixed connection of the wear-resistant block 2 and the support column 3.

[0030] Further, on the basis of the above structure, the support column 3 is formed with a spring cavity 32 extending through the support column 3 to one end, and the limiting rod 5 is arranged on the side wall of the spring cavity 32 and can slide radially along the support column 3. The end of the connecting bolt 22 penetrates into the spring cavity 32 and abuts against the end of the limiting rod 5, so that the other end of the limiting rod 5 is kept in the limiting ring groove 12. One end of the buffer spring 6 penetrates into the spring cavity 32 and abuts against the abutting ring 33 formed on the inner wall of the spring cavity 32. After the connecting bolt 22 is threaded in the insertion pile 31, the end thereof penetrates into the spring cavity 32 and abuts against the end of the limiting rod 5 on one side of the end of the limiting rod 5. The limiting of the connecting bolt 22 keeps the other end of the limiting rod 5 in the limiting ring groove 12, limiting the sliding of the support column 3 along the axial direction thereof. After the connecting bolt 22 is removed, the end of the limiting rod 5 in the limiting ring groove 12 is withdrawn from the limiting ring groove 12 by the inward sliding of the limiting rod 5 on the support column 3, so that the support column 3 can be taken out from the sliding cavity 13, thereby facilitating the replacement of the buffer spring 6 and the buffer pad 4, to ensure the shock-absorbing effect of the two on the wear-resistant block 2.

[0031] Further, on the basis of the above structure, the limiting rod 5 is formed with a spring abutting plate 51, a spring hole 34 is formed in the inner wall of the spring cavity 32 and opposite to the spring abutting plate 51, a return spring 7 is arranged in the spring hole 34 and abuts on the spring abutting plate 51, a limiting sliding groove 35 is formed in the bottom wall of the spring cavity 32 and along the radial direction of the supporting column 3, the spring abutting plate 51 is formed with a limiting protrusion 52 which is kept in the sliding groove, after the connecting bolt 22 is removed, the limiting rod 5 slides inward on the supporting column 3 under the action of the return spring 7 so that the end of the limiting rod 5 exits the limiting ring groove 12, further facilitating the operation of removing the supporting column 3 and replacing the buffer spring 6 and the buffer pad, the limiting protrusion 52 and the limiting sliding groove 35 cooperate to limit the sliding of the limiting rod 5 on the supporting column 3, preventing the limiting rod 5 from falling off the supporting column 3 when driven by the return spring 7, thereby facilitating the operation of removing the supporting column 3 and replacing the buffer spring 6 and the buffer pad.

[0032] A ball mill for quartz powder production, comprising the ball mill lining plate for quartz powder production, a plurality of the ball mill lining plate for quartz powder production is fixedly connected to the inner wall of the barrel of the ball mill by screwing the nut after the mounting screw rod 14 passes through the barrel of the ball mill, and is closely arranged on the inner wall of the barrel, plays a role of buffering and damping during the operation of the ball mill, reduces the noise during the operation of the ball mill, and prolongs the service life of the wear-resistant block 2 to ensure the working efficiency of the ball mill.

[0033] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
