Description

Technical Field

[0001] The present application relates to the field of ball mills, and in particular to a ball mill for ceramic production. Background Art

[0002] Ceramics is a common material, widely used in construction, home furnishing, decoration and other fields. Dry powder making is a commonly used method for making ceramics.

[0003] Dry pulverizing refers to a method of converting raw materials such as clay into fine powder through physical or chemical methods, and then performing molding, firing and other processing techniques to produce ceramic products. The main steps of dry pulverizing include screening, grinding, mixing, and crushing of raw materials. Among them, grinding is the key step in dry pulverizing. Currently, ball mills are often used to grind raw materials into fine powder.

[0004] Currently, a Chinese utility model patent with publication number CN211487947U discloses a ball mill comprising a base, a bearing seat, a main bearing, a cylinder, steel balls, and a support. The feed and discharge ports at both ends of the cylinder are shaft tubes, each mounted in the main bearing, which is fixed to the bearing seat, which is fixed to the base. A spiral discharge chute is provided on the inner wall of the cylinder near the discharge port. A feed hopper is movably connected to the outer end of the feed port. Heat dissipation holes are evenly distributed on the side walls of the cylinder, each of which is connected to a heat pipe, the outer ends of which are sealed. A wear-resistant lining is fixedly mounted on the inner wall of the cylinder, which is provided with sieve holes connected to the heat dissipation holes. Steel balls are placed in the inner cavity of the cylinder, and their cross-sectional diameter is larger than the aperture of the sieve holes. The bottom ends of the support pillars are fixed to the base, which is provided with socket holes corresponding to the support pillars. This utility model has better heat dissipation performance.

[0005] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: long-term use of the ball mill will cause wear of the liner, and the liner needs to be replaced in a timely manner. However, there are always steel balls and some residual materials in the cylinder. Therefore, the staff need to remove the steel balls and residual materials from the cylinder before replacing the liner. It is difficult to remove the steel balls, resulting in low work efficiency. Utility Model Content

[0006] In order to facilitate workers to remove steel balls from the ball mill, the present application provides a ball mill for ceramic production.

[0007] This application provides a ball mill for ceramic production, which adopts the following technical solution:

[0008] A ball mill for ceramic production includes a frame, a cylinder, a rotating frame, a tilting assembly, and a driving assembly for driving the cylinder to rotate. The rotating frame includes a mounting block and a rotating ring. The rotating ring is coaxially arranged with the cylinder and rotatably connected to the outer wall of the cylinder. The mounting block is arranged on the frame, and the rotating ring is rotatably connected to the mounting block along the horizontal direction. One end of the cylinder is open. The tilting assembly is used to tilt the cylinder and keep the cylinder open downward. A sealing assembly is provided on the cylinder for sealing the cylinder opening.

[0009] By adopting the above technical solution, when the staff needs to replace the liner in the cylinder, the staff can first discharge the material from the discharge port of the cylinder. Since the cylinder is in a horizontal state, the steel balls and some residues cannot be discharged from the discharge port. The staff first separates the sealing assembly of the bayonet originally used for sealing from the opening of the cylinder. Then the staff can start the tilting assembly. The tilting assembly can drive the cylinder to rotate along the rotating axis of the rotating ring and the mounting block, so that the cylinder is tilted. The residual material and steel balls in the cylinder are dumped from the opening of the cylinder under the action of gravity. The steel balls and residual materials are separated from the cylinder, which is convenient for the staff to replace the liner in the cylinder and improves work efficiency.

[0010] Optionally, the tilting assembly includes a mounting bracket, a connecting rod and a driving cylinder, the driving cylinder is arranged on the frame, one end of the connecting rod is rotatably connected to the piston rod of the driving cylinder, the mounting bracket is rotatably connected to the other end of the connecting rod, and the mounting bracket is rotatably connected to the cylinder along the axis of the cylinder.

[0011] By adopting the above technical solution, the mounting frame is connected to the cylinder body by rotating along the axial direction of the cylinder body, and the connecting frame does not interfere with the driving component to drive the cylinder body to rotate. When the cylinder body needs to be tilted to dump the steel balls, the staff can extend the piston rod of the driving cylinder and put the connecting rod that was originally in a tilted state into a vertical state. The connecting rod drives the mounting frame to move, and the mounting frame can drive the cylinder body to rotate along the rotating ring and the rotating axis of the cylinder body. The cylinder body can maintain a tilted state. The tilting component has a simple structure and is easy for the staff to operate.

[0012] Optionally, a feeding assembly is provided at the cylinder away from the outlet, and the feeding assembly includes a connecting pipe, a feeding pipe, a feeding motor and a feeding screw. The connecting pipe is coaxially arranged with the cylinder, one end of the connecting pipe is inserted into the cylinder, the connecting pipe is arranged on the mounting frame, the end of the connecting pipe away from the cylinder is sealed, one end of the feeding pipe is arranged on the side wall of the connecting pipe, the feeding pipe is communicated with the connecting pipe, the feeding screw is coaxially arranged with the connecting pipe, the feeding screw is rotatably connected to the connecting pipe, and the feeding motor is used to drive the feeding screw to rotate.

[0013] By adopting the above technical solution, the feeding assembly is used to feed the material into the barrel for grinding. The staff passes the material into the connecting pipe through the feeding pipe. When the barrel is in the grinding state, it is in a horizontal state. Therefore, the material in the connecting pipe needs to be fed into the barrel through the feeding screw. The feeding motor drives the feeding screw to rotate, and the feeding screw feeds the material to be ground into the barrel through the connecting pipe. Since the barrel rotates during the grinding process, the barrel rotates relative to the connecting frame. The connecting pipe is arranged on the connecting frame, and the structure is reasonable. The feeding assembly is convenient for the staff to feed the material into the barrel.

[0014] Optionally, a sliding ring is provided on the outer wall of the cylinder, the sliding ring is slidingly connected to the cylinder along the axis of the cylinder, the rotating ring is rotatably connected to the sliding ring, and a sliding member for driving the sliding ring to move is provided on the cylinder.

[0015] By adopting the above technical solution, the staff can change the rotation axis of the cylinder when it is tilted by the position of the slip ring. The change in the position of the slip ring can change the tilt angle of the cylinder, so that the speed at which the steel ball leaves the cylinder changes, making it easier for the staff to catch the steel ball or reducing the time it takes for the steel ball to leave the cylinder.

[0016] Optionally, the sliding member includes a sliding screw and a sliding motor, the length direction of the sliding screw is parallel to the axis of the cylinder, the sliding screw is rotatably connected to the outer wall of the cylinder, the sliding ring is threadedly connected to the sliding screw, and the sliding motor is used to drive the sliding screw to rotate.

[0017] By adopting the above technical solution, when the staff needs to adjust the inclination angle of the cylinder, the staff drives the sliding motor, the sliding motor drives the sliding screw to rotate, and the sliding screw drives the sliding ring to move along the axial direction of the cylinder. The sliding ring can drive the rotating ring to move, and the rotating ring moves relative to the cylinder, which can change the rotation axis of the cylinder's inclination and the inclination angle of the cylinder, so that the staff can adapt to the speed at which the steel balls fall from the opening of the cylinder, making it easier for the staff to collect the steel balls.

[0018] Optionally, the driving assembly includes a driving gear, a driving ring gear and a driving motor, the driving ring gear is coaxially arranged with the cylinder, the driving ring gear is arranged on the outer wall of the cylinder, the driving motor is arranged on the frame, the driving gear is arranged on the output shaft of the driving motor, and the driving gear is used to engage with the driving ring gear when the cylinder is in a horizontal state.

[0019] By adopting the above technical solution, when the cylinder needs to grind the material, it is necessary to first ensure that the cylinder is in a horizontal state. At this time, the driving gear and the driving ring gear are in a meshing state. The staff can drive the driving motor to start, and the driving motor drives the driving gear to rotate. The driving gear drives the driving ring gear to rotate, and the driving ring gear can drive the cylinder to rotate. The rotation of the cylinder will bring up the steel balls and hit the material at the bottom of the cylinder. The material is ground inside the cylinder. The driving component has a simple structure and allows the staff to confirm that the cylinder is in a horizontal state.

[0020] Optionally, the sealing assembly includes a sealing plate and several sealing bolts, the sealing plate is used to abut against the opening of the cylinder, and the several sealing bolts are distributed around the opening of the cylinder, the tail of the sealing bolt passes through the sealing plate and is threadedly connected to the cylinder, and a discharge pipe for discharging is provided on the sealing plate.

[0021] By adopting the above technical solution, when the cylinder is grinding, it is necessary to use a sealing assembly to seal the opening of the cylinder to reduce the material from escaping from the cylinder during the grinding process. The staff can first abut the sealing plate against the opening of the cylinder, and then connect the sealing plate to the cylinder through the sealing bolt to reduce the material from flowing out of the opening of the cylinder. The discharge pipe is connected to the subsequent equipment, and when the material is ground, it will be discharged to the subsequent equipment through the discharge pipe.

[0022] Optionally, a sealing ring is provided on the sealing plate, and a sealing groove is provided on the cylinder, and the sealing groove is used for clamping with the sealing ring.
