Description

Technical Field

[0001] The invention belongs to the field of ceramic mud processing and relates to ball mill technology, in particular to a ceramic mud ball mill for ceramic production. Background Art

[0002] During the ceramic production process, the clay needs to be poured into a ball mill, crushed by the impact of the grinding balls inside the ball mill, and then fully mixed with water to form slurry.

[0003] The reference patent name is: A ball mill for processing ceramic mud (patent announcement number: CN116351521A). A rotating scraper plate is arranged inside the ball mill, and the direction of the scraper plate is opposite to the overall direction of the ball mill. When the ball mill rotates to cause the grinding balls and mud to collide, the scraper plate rotates and collides with the grinding balls, further enhancing the power of the grinding balls to move, accelerating the collision process, and reducing the grinding time. At the same time, a cleaning brush that fits the filter screen is arranged on the surface of the scraper plate. When the ball mill is rotated vertically to pour the material, the mud on the surface of the filter screen can be pushed and the grinding balls can be prevented from blocking the pouring route.

[0004] However, when implementing the above technical solution, the following problems exist: during the pouring process of the above device, the mud is directly poured out after passing through the filter screen, and the cleaning brush stirs the mud and clears the gaps on the surface of the filter screen. However, when the ball mill is in a vertical position for pouring, all the mud inside the ball mill is concentrated to exert pressure on the filter screen, thereby increasing the resistance of the scraper plate, and after the grinding balls fall onto the filter screen, the resistance of the scraper plate will be further increased. The larger resistance will affect the cleaning effect of the scraper plate on the filter screen, and the relatively large mud particles will clog the filter screen, prolonging the time required for filtration.

[0005] Therefore, the present invention provides a ceramic slurry ball mill for ceramic production. Summary of the invention

The transfer ring 7 is meshed with the driving gear 6. The inside of the tank body is rotatably connected with a scraper rod 9. The scraper rod 9 is fixedly connected with a triangular block at one end close to the transfer ring 7. The surface of the transfer ring 7 is provided with tooth grooves, and the triangular block is adapted to the tooth grooves.

[0036] The ceramic mud ball mill for ceramic production, in actual application, is provided with a plurality of support blocks 1 on the surface of the rotating frame, and a sliding extrusion block 3 and a positioning block 2 are provided inside the support block 1. The contact between the extrusion block 3 and the positioning block 2 and the filter screen can fix the position of the filter screen relative to the rotating frame, and the positioning block 2 and the extrusion block 3 can slide on the surface of the support block 1, and then the sliding of the two can drive the filter screen to slide, and the sliding of the filter screen passes through the transfer ring 7, the driving gear 6 and the triangular block at one end of the scraper rod 9. The rotation of the scraper rod 9 can cause the driving gear 6 to rotate, and then drive the extrusion block 3 and the positioning block 2 to slide on the surface of the penetration rod, so that the filter screen can reciprocate. In the process of mud flowing down through the filter screen, the reciprocating movement of the filter screen can further prevent the filter screen from being blocked, and accelerate the mud discharge speed;

[0037] In some specific embodiments, the sealing assembly includes a sliding ring 10 fixedly arranged on the surface of the positioning block 2 and the extrusion block 3, the distance between the two sliding rings 10 is equal to the distance between the positioning block 2 and the extrusion block 3, and the height of the sliding ring 10 is greater than the height of the support block 1, and the surface of the tank body is provided with a sliding groove 11, the cross-section of the sliding groove 11 is C-shaped, and the sliding groove 11 is adapted to the sliding ring 10; through the connection between the sliding groove 11 and the sliding ring 10, it can be ensured that during the sliding process of the positioning block 2 and the extrusion block 3, there will be no large area gap at this position, thereby preventing the mud inside the tank body from flowing out; and the sliding groove 11 and the sliding ring 10 can rotate independently, and the position of the filter screen, the positioning block 2 and the extrusion block 3 will not be affected during the rotation of the tank body;

[0038] In some specific implementation schemes, the two sides of the positioning block 2 are fixedly connected to the limiting blocks 12, the surface of the support block 1 is provided with limiting grooves, the limiting blocks 12 are adapted to the limiting grooves, and the limiting springs 13 are fixedly connected between the limiting blocks 12 and the limiting grooves; when the limiting springs 13 are in a natural state, the positioning block 2 is in contact with the support block 1; the sliding distance of the positioning block 2 can be limited by the external limiting blocks 12, and the limiting springs 13 are arranged between the limiting blocks 12 and the limiting grooves, so as to provide a certain restoring force during the movement of the positioning block 2 and the limiting blocks 12;

[0041] In some specific embodiments, a plurality of insert blocks 17 are slidably connected inside the rotating frame, and a supporting groove (not shown in the figure) is provided on the surface of the insert block 17, the diameter of the supporting groove (not shown in the figure) is larger than the aperture of the filter screen, and the diameter of the supporting groove (not shown in the figure) is smaller than the diameter of the grinding ball, and the distance between the insert block 17 and the filter screen is smaller than the distance between the insert block 17 and the side of the tank body away from the filter screen; the supporting groove can block a plurality of grinding balls before reaching the filter screen, thereby making the gravity on the surface of the filter screen relatively reduced, thereby avoiding excessive load on the power source on the surface of the tank body;

[0042] It should be noted that the insert block 17 is arc-shaped on the side away from the filter screen, and the center of the arc is away from the filter screen. The vertical distance between the lowest point of the bottom of the arc and the side of the filter screen is less than the diameter of the grinding ball. There is a gap in the middle of the scraper rod 9, and the position of the gap corresponds to the position of the insert block 17. After the insert block 17 is inserted into the tank body, the surface of the scraper rod 9 fits with it, and the grinding balls on the surface of the insert block 17 can be displaced to avoid excessive accumulation of mud on the surface of the grinding balls, which causes blockage at this position.

[0043] In a further embodiment, a plurality of movable shafts 16 are fixedly connected to the surface of the rotating frame, and movable grooves are provided on the surface of the insertion block 17, and the movable shafts 16 are adapted to the movable grooves; a synchronous ring 18 is rotatably connected to the surface of the rotating frame, and a plurality of oblique grooves 19 are provided on the surface of the synchronous ring 18, and there is an angle between the oblique grooves 19 and the movable grooves projected on the surface of the insertion block 17, and oblique shafts are fixedly connected to the surface of the insertion block 17, and the oblique shafts are adapted to the oblique grooves 19; the insertion block 17 can be driven to move by rotation through the movable grooves and the oblique grooves 19 with an angle, and the rotation of a single synchronous ring 18 can cause all the insertion blocks 17 to move, which is convenient for control;

[0044] In a further embodiment, the two sides of the insert block 17 are rotatably connected with a connecting block 20, and the other end of the connecting block 20 is rotatably connected to the tank body, and the adjacent connecting blocks 20 are fitted together; the connecting blocks 20 can fill the gap between the adjacent insert blocks 17 after the insert block 17 moves to the outside of the tank body, thereby avoiding leakage at this position;

[0045] It should be noted that there is a groove on the surface of the insertion block 17, and the connection block 20 can slide inside the groove and can be completely fitted with the insertion block 17. After the connection block 20 and the insertion block 17 are fitted, the other side of the connection block 20 is flush with the edge of the insertion block 17;

[0046] In a further embodiment, a single insert block 17 is rotatably connected to a transfer rod 21 at one side away from the tank body, and a transfer shaft 22 is slidably connected to the end of the transfer rod 21 away from the insert block 17, and a rotating shaft is fixedly connected to the surface of the rotating shaft 22, and the rotating shaft is T-shaped, and a through groove is opened at one end of the transfer rod 21, and the rotating shaft is adapted to the through groove, and the height of the rotating shaft is greater than the width of the transfer rod 21; the end of the transfer shaft 22 away from the transfer rod 21 is fixedly connected to the abutting rod 15; the position of the transfer shaft 22 relative to the insert block 17 can be changed by the rotation of the abutting rod 15, and the transfer shaft 22 rotates while descending or ascending, and the rotation of the transfer shaft 22 causes the transfer rod 21 to rotate through the rotating shaft, thereby pushing the insert block 17 to move, and then the reciprocating movement of the filter screen is associated with the movement of the insert block 17, to ensure that the insert block 17 can support most of the grinding balls when the mud is discharged;

[0047] Working principle of the present invention:

[0048] After the mud material is ground into mud, first rotate the abutting rod 15 to prompt the driving gear 6 to move away from the clamping block, and then drive the gear 6 and the transfer ring 7 to engage. At the same time, the rotation of the abutting rod 15 prompts the transfer shaft 22 to rotate, changing the position of one end of the transfer rod 21, prompting a single insertion block 17 to move into the tank body. The single insertion block 17 moves through the oblique groove 19 and the oblique shaft to push the synchronous ring 18 to rotate, prompting all the remaining insertion blocks 17 to move into the tank body. Then the rotating frame can be rotated to prompt the rotating frame to be perpendicular to the ground, and the mud moves toward the surface of the filter screen. Some grinding balls contact the insertion blocks 17. At this time, the rotation of the scraper rod 9 drives the transfer ring 7 to rotate through the triangular block, and then drives the driving gear 6 to rotate. The rotation of the driving gear 6 drives the clamping block and the positioning block 2 to slide inside the support block 1 through the arc groove and the driving shaft 8, and the filter screen moves back and forth.

[0049] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
