Description

Technical Field

[0001] The present invention relates to the technical field of ball mills, and specifically relates to a ball mill for ceramic manufacturing. Background Art

[0002] Before ceramics are manufactured, the raw materials for ceramic manufacturing need to be crushed, and at this time, a ball mill is required. A ball mill is a device that uses grinding balls to crush materials. When the grinding balls move inside the grinding cylinder, the grinding balls can impact the materials inside the grinding cylinder, which can achieve the grinding and crushing of the materials inside the grinding cylinder.

[0003] After retrieval, the existing patent publication number CN118454817A shows a ball mill for ceramic manufacturing, which is used to grind the raw materials for ceramic products. The device magnetically attracts auxiliary steel balls on the push plate, and then energizes the push plate. The energized push plate can drive the auxiliary steel balls to push the materials, thereby achieving the impact crushing of the materials by the auxiliary steel balls.

[0004] During the actual use of this device, although it can achieve a good crushing effect on the materials, there are still some deficiencies in its actual use, such as:

[0005] The device magnetically attracts the auxiliary steel balls on the push plate by magnetic attraction. Although it can achieve the impact of the energized push plate driving the auxiliary steel balls on the materials, it is not convenient for the steel balls to roll inside the ball mill cylinder, which results in the inability to grind the finer materials inside the ball mill cylinder well, thereby reducing the grinding efficiency of the materials inside the cylinder.

[0006] Therefore, we propose a ball mill for ceramic manufacturing. Summary of the Invention

[0007] One technical problem to be solved by the present application is that it is not convenient for the steel balls in the ball mill to roll inside the ball mill cylinder, which results in the inability to grind the finer materials inside the ball mill cylinder well.

[0008] To solve the above technical problem, the embodiments of the present application provide a ball mill for ceramic manufacturing, including a driving structure and a grinding barrel connected to the driving structure. The inside of the grinding barrel is rotatably provided with liners at equal intervals. One end of the liner abuts against the grinding barrel. A connecting seat is arranged between the liner and the grinding barrel. A first magnet is fixedly connected to a part of the outer side of the liner away from the connecting seat, and a second magnet is fixedly connected to a part of the inner wall of the grinding barrel close to the first magnet.

[0009] In some embodiments, bolt holes are provided on the grinding barrel, and a first fixing bolt penetrates through the bolt holes. One end of the first fixing bolt that penetrates through the bolt holes is screwed into the inside of the connecting seat.

[0010] In some embodiments, the connecting seat includes a hinge fixedly connected to the upper end of the connecting seat and a fixed seat fixedly connected to the lower end of the connecting seat, the end of the hinge facing away from the connecting seat is fixedly connected to the lining plate, and the side of the fixed seat facing away from the connecting seat is fixedly connected to the grinding barrel.

[0011] In some embodiments, a fixing groove is opened on the inner side of the grinding barrel, the second magnetic block is embedded in the fixing groove, and a second sealing sheet is fixedly connected to the fixing groove.

[0012] In some embodiments, a second fixing bolt is fixedly connected to the grinding barrel, and one end of the second fixing bolt passing through the grinding barrel is screwed into the interior of the second magnetic block, and the magnetic poles of the second magnetic block repel the magnetic poles of the first magnetic block.

[0013] In some embodiments, the lining plate includes a support plate and a sieve plate fixedly connected to the support plate, the sieve plate abuts against the grinding barrel, and the bottom surface of the sieve plate is fixedly connected to the hinge.

[0014] In some embodiments, a connecting groove is formed on one side of the support plate close to the second magnetic block, the first magnetic block is embedded in the connecting groove, and a first sealing sheet is fixedly connected to the connecting groove.

[0015] In some embodiments, the support plate is an arc-shaped structure, one end of the support plate facing away from the sieve plate is tilted toward the central axis of the grinding barrel, and the cross-section of the sieve plate is rectangular.

[0016] In some embodiments, the sieve plate is distributed at one end of the support plate close to the rotation direction of the grinding barrel, and grinding balls are distributed inside the grinding barrel, and the grinding balls can collide with the support plate.

[0017] In some embodiments, the length of the support plate is greater than that of the sieve plate, the support plate and the sieve plate are fixed as one body, and an angle is formed at one end of the sieve plate that contacts the grinding barrel.

[0018] The present invention has at least the following beneficial effects:

[0019] 1. When the ductile iron mill is in actual use, the grinding balls can hit the support plate. Since the support plate and the screen plate are fixed as a whole, a hinge is provided between the screen plate and the connecting seat. This allows the grinding balls to hit the support plate, and the larger materials on the screen plate will be thrown backwards, so that the larger materials on the screen plate can hit the grinding balls and the inner wall of the grinding barrel again, thereby accelerating the crushing efficiency of the materials.

[0020] 2. When the spherical inkjet mill is in actual use, the grinding balls that fall onto the support plate will move backwards under the action of their own gravity and the rotation of the grinding barrel. At this time, the grinding balls will pre-grind the materials on the screen plate, which can improve the grinding efficiency of the grinding balls on the materials on the screen plate.

[0021] 3. When the nodular graphite machine is actually in use, the sieve plate can screen the materials inside the grinding barrel. When the sieve plate screens the materials, the smaller materials will penetrate through the sieve plate. At this time, the smaller materials will penetrate through the sieve plate. As the grinding barrel rotates, the materials screened by the sieve plate will contact the subsequent sieve plate. At this time, the grinding balls separated from the support plate will first impact the smaller materials, and then when the grinding balls separated from the support plate move, they can also grind the better materials.

Detailed Embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1: Please refer to Figures 1-10 , the present invention provides a technical solution:

[0035] A ball mill for ceramic manufacturing, including a driving structure 1 and a grinding barrel 2 connected to the driving structure 1. Liners 3 are rotatably arranged at equal intervals inside the grinding barrel 2. One end of the liner 3 abuts against the grinding barrel 2. A connecting seat 5 is arranged between the liner 3 and the grinding barrel 2. A first magnetic block 6 is fixedly connected to a portion of the outer side of the liner 3 away from the connecting seat 5. A second magnetic block 7 is fixedly connected to a portion of the inner wall of the grinding barrel 2 close to the first magnetic block 6. Grinding balls 8 are distributed inside the grinding barrel 2;

[0036] The driving structure 1 can be selected from existing structures on the market. Its role in this document is to drive the grinding barrel 2 to rotate along the axis of the grinding barrel 2. The liners 3 inside the grinding barrel 2 are used to drive the grinding balls 8 inside the grinding barrel 2 to move, and can also agitate the materials inside the grinding barrel 2. The liners 3 are installed inside the grinding barrel 2 through the connecting seat 5. During actual use, the connecting seat 5 is used to support the liner 3. The connecting seat 5 and the liner 3 can form a lever structure. The magnetic poles of the first magnetic block 6 and the second magnetic block 7 repel each other, which can achieve that the first magnetic block 6 and the second magnetic block 7 do not attract under normal conditions, and at the same time, the end of the liner 3 away from the connecting seat 5 is tilted up.

[0037] Bolting holes 22 are formed on the grinding barrel 2. A first fixing bolt 4 penetrates through the inside of the bolting holes 22, and the end of the first fixing bolt 4 penetrating through the bolting holes 22 is screwed into the inside of the connecting seat 5;

[0038] The first fixing bolt 4 can be fixed to the connecting seat 5 through the bolting holes 22, which can achieve the stable connection of the connecting seat 5 inside the grinding barrel 2 and realize the connection of the connecting seat 5 driving the liner 3 inside the grinding barrel 2.

[0039] The connecting seat 5 includes a hinge 51 fixedly connected to the upper end of the connecting seat 5 and a fixed seat 52 fixedly connected to the lower end of the connecting seat 5. The end of the hinge 51 away from the connecting seat 5 is fixedly connected to the liner 3. The side of the fixed seat 52 away from the connecting seat 5 is fixedly connected to the grinding barrel 2;

[0040] One end of the first fixing bolt 4 and the bolt hole 22 passing through can be screwed into the inside of the fixing seat 52, so that the fixing seat 52 can be firmly connected inside the grinding barrel 2. When the hinge 51 and the lining plate 3 are connected, the lining plate 3 can rotate around the hinge 51, and the lining plate 3 and the connecting seat 5 form a lever structure.

[0041] A fixing groove 21 is formed on the inner side of the grinding barrel 2, the second magnet 7 is embedded inside the fixing groove 21, and a second sealing piece 23 is fixedly connected to the fixing groove 21.

[0042] A second fixing bolt 24 is fixedly connected to the grinding barrel 2. One end of the second fixing bolt 24 passing through the grinding barrel 2 is screwed into the second magnet 7. The magnetic poles of the second magnet 7 and the first magnet 6 repel each other;

[0043] The second fixing bolt 24 can drive the second magnet 7 to be fixed inside the fixing groove 21, and the second magnet 7 can be firmly installed on the grinding barrel 2.

[0044] The lining plate 3 includes a supporting plate 31 and a sieve plate 34 fixedly connected to the supporting plate 31. The sieve plate 34 abuts against the grinding barrel 2, and the bottom surface of the sieve plate 34 is fixedly connected to the hinge 51;

[0045] When the bottom surface of the sieve plate 34 is fixedly connected to the hinge 51, the sieve plate 34 can rotate around the hinge 51, and the materials on the sieve plate 34 can be thrown backward. The sieve plate 34 is a hole plate structure with holes, and its function in this document is to screen the materials inside the grinding barrel 2.

[0046] A connecting groove 32 is formed on one side of the supporting plate 31 close to the second magnet 7. The first magnet 6 is embedded inside the connecting groove 32, and a first sealing piece 33 is fixedly connected to the connecting groove 32;

[0047] The second sealing piece 23 and the first sealing piece 33 have the same structure. The second sealing piece 23 and the first sealing piece 33 are made of materials available on the market. The materials selected for the second sealing piece 23 and the first sealing piece 33 cannot block the magnetism of the second magnet 7 and the first magnet 6. During actual use, the second sealing piece 23 can seal the inner cavity of the fixing groove 21, and the first sealing piece 33 seals the inner cavity of the connecting groove 32;

[0048] When the ball mill is actually in use, the user first injects the materials required in the ceramic manufacturing process into the interior of the grinding barrel 2, and at the same time places the grinding balls 8 inside the grinding barrel 2. The quantities of the grinding balls 8 and the materials injected during the ceramic manufacturing process are determined according to the actual usage. When the driving structure 1 drives the grinding barrel 2 to rotate, the grinding balls 8 and the materials in the ceramic manufacturing process can collide and rub against each other, which can achieve the rapid pulverization of the materials in the ceramic manufacturing process inside the grinding barrel 2. As the driving structure 1 drives the grinding barrel 2 to continuously rotate, the grinding balls 8 and the materials in the ceramic manufacturing process can flow backward inside the grinding barrel 2. Refer to the attached Figure 3 , for the sake of easy understanding, the materials inside the grinding barrel 2 are divided into three regions A, B, and C. Among them, the materials in region A are the materials distributed on the lining plate 3 when the grinding barrel 2 rotates, region B is the materials distributed between the lining plate 3 and the grinding barrel 2 when the grinding barrel 2 rotates, and region C is the materials of A and B flowing onto the sieve plate 34. When the materials in regions A and B flow into region C, the materials inside region C will be screened, which can achieve that the larger particle materials are distributed on the sieve plate 34. Since when the supporting plate 31 is squeezed, the supporting plate 31 can drive the sieve plate 34 to flip around the hinge 51, and during the backward flow of the materials, the supporting plate 31 can be squeezed. At this time, the sieve plate 34 flips around the hinge 51, which can achieve the sieve plate 34 to stir the larger particle materials inside the grinding barrel 2. This process can be referred to in the attached Figure 6 , when the sieve plate 34 stirs the materials, the grinding barrel 2 can rotate driven by the driving structure 1. At this time, the materials scattered by the sieve plate 34 can hit the sieve plate 34 behind, which can achieve the re-pulverization of the larger materials inside the grinding barrel 2, and thus can improve the pulverization efficiency of the materials inside the grinding barrel 2;

[0049] It should be noted that since the magnetic poles of the first magnetic block 6 and the second magnetic block 7 repel each other, when the lining plate 3 is distributed inside the grinding barrel 2, the end of the sieve plate 34 can abut against the inner wall of the grinding barrel 2, which is convenient for the materials in regions A and B to flow into region C. Refer to the attached Figure 3 , when the driving structure 1 continuously drives the grinding barrel 2 to rotate, the materials in regions A and B and the grinding balls 8 can also flow into region C. During this process, the grinding balls 8 can generate greater friction with the materials, which can achieve the rapid grinding of the materials inside the grinding barrel 2 by the grinding balls 8, and thus can improve the grinding efficiency of the materials inside the grinding barrel 2.

[0050] Embodiment 2: On the basis of Embodiment 1, this embodiment proposes an optimized technical solution:

[0051] The supporting plate 31 is of an arc-shaped structure, and the end of the supporting plate 31 facing away from the sieve plate 34 warps towards the central axis of the grinding barrel 2, and the cross-section of the sieve plate 34 is rectangular.

[0052] The sieve plate 34 is distributed at one end of the support plate 31 close to the rotation direction of the grinding barrel 2. The length of the support plate 31 is greater than that of the sieve plate 34. The support plate 31 and the sieve plate 34 are integrally fixed. An inclined angle is provided at one end of the sieve plate 34 in contact with the grinding barrel 2, and the grinding balls 8 can strike the support plate 31;

[0053] The inclined angle provided on the sieve plate 34 can enable the end of the sieve plate 34 to be well abutted against the grinding barrel 2, and can enable the materials inside the grinding barrel 2 to be well conveyed onto the sieve plate 34. Since the support plate 31 and the sieve plate 34 are integrally fixed, when the grinding balls 8 strike the support plate 31, the support plate 31 can drive the sieve plate 34 to rotate around the hinge 51;

[0054] When the materials and the grinding balls 8 inside the A and B regions flow into the C region, some of the grinding balls 8 can move upward under the drive of the grinding barrel 2. As the drive structure 1 continuously drives the grinding barrel 2 to rotate, the upward-moving grinding balls 8 can fall onto the support plate 31 under the action of gravity. At this time, the grinding balls 8 can strike the support plate 31. Before the support plate 31 is struck by the grinding balls 8, the materials inside the B region can flow into the C region. Reference can be made to the attached Figure 3 and the attached Figure 5 This can enable the support plate 31 to drive the sieve plate 34 to rotate around the hinge 51 when the support plate 31 is struck by the grinding balls 8. When the sieve plate 34 rotates around the hinge 51, the sieve plate 34 can screen the materials inside the grinding barrel 2. As the sieve plate 34 continuously flips, the sieve plate 34 can drive the larger-particle materials to be thrown backward, thereby enabling the larger-particle materials to strike the rear lining plate 3. Reference can be made to the attached Figure 5 When the grinding balls 8 strike the support plate 31, the first magnetic block 6 on the support plate 31 can approach the second magnetic block 7. Since the second magnetic block 7 can provide a repulsive force to the first magnetic block 6, this can enable the first magnetic block 6 to drive the support plate 31 to reset when the first magnetic block 6 approaches the second magnetic block 7. At this time, the grinding balls 8 can be separated from the support plate 31, thereby enabling the grinding balls 8 to roll into the sieve plate 34 on the rear lining plate 3. During this process, the grinding balls 8 can grind the materials used in the ceramic manufacturing process;

[0055] It should be noted that when the sieve plate 34 drives the materials of larger particles to be thrown backward, the materials of larger particles impact on the rear lining plate 3. As the driving structure 1 continuously drives the grinding barrel 2 to rotate, the materials of larger particles will enter the B area under the action of gravity. At this time, the materials of larger particles will be mixed with the materials of smaller particles in the B area. At the same time, the grinding balls 8 can also enter the B area. During the mixing process, the materials of larger particles, the materials of smaller particles and the grinding balls 8 will rub against each other, which can further improve the grinding efficiency of the materials. When the grinding barrel 2 continues to rotate, the materials in the B area will be mixed with the materials in the A area and enter the C area. This process can be referred to in the attached Figure 3 , and the mixed materials will rub against each other inside the C area, which can facilitate the mixed grinding of materials of different grades;

[0056] When the materials in the B area flow into the C area, the grinding balls 8 can impact the support plate 31. At this time, the first magnetic block 6 on the support plate 31 can gradually approach the second magnetic block 7. As the first magnetic block 6 gradually approaches the second magnetic block 7, the remaining materials in the B area can be extruded. Of course, there may be no remaining materials in the B area. In order to prevent the remaining materials in the B area from affecting the normal use of the support plate 31, the support plate 31 is set as an arc-shaped structure. When the arc-shaped support plate 31 extrudes the materials, the materials in the B area can flow to both sides, which can prevent the materials in the B area from concentrating under the support plate 31 and avoid the materials in the B area from affecting the normal use of the support plate 31;

[0057] At the same time, in order to prevent the friction generated by the materials from damaging the first magnetic block 6 and the second magnetic block 7 when the materials in the B area flow into the C area, a first sealing piece 33 is arranged at the installation position of the first magnetic block 6, and a second sealing piece 23 is arranged at the position of the second magnetic block 7. The settings of the first sealing piece 33 and the second sealing piece 23 can prevent the materials from directly contacting the first magnetic block 6 and the second magnetic block 7, which can avoid the first magnetic block 6 and the second magnetic block 7 from being easily worn during use, and thus can extend the service life of the first magnetic block 6 and the second magnetic block 7.

[0058] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
