Description

Technical Field

[0001] This invention relates to the field of ball rolling device technology, specifically a ball rolling device for ceramic powder. Background Technology

[0002] Ceramics is a general term for pottery and porcelain. The raw materials used in ceramics are mostly natural minerals or rocks, primarily silicate minerals. Therefore, ceramic materials generally have high hardness and poor plasticity. Thus, in the current ceramic powder processing stage, ball mills are used to pulverize the ceramic powder. The most commonly used ball mill is the ball mill. Existing ball mills mainly consist of a drive structure, a drum, and internal balls. The balls are lifted and then fall under the rotation of the drum, impacting and crushing the raw materials as they fall, thus achieving a crushing effect. Ball mills are mainly used for secondary pulverization after raw material crushing, achieving fine grinding and pulverization. However, existing ball mills still have some problems, as follows:

[0003] Existing ball mills mix raw materials and balls entirely within the drum, then use the drum to continuously lift and drop the materials and balls for crushing. However, this method causes raw materials that have reached the crushing standard to be repeatedly crushed within the drum, preventing timely separation and discharge from the current crushing structure. This means the entire crushing process requires all raw materials to reach the crushing level before the mill can be stopped and unloaded. This significantly impacts the overall production efficiency of existing ball mills. Furthermore, during the crushing process, when the balls fall from a height to the bottom of the drum, the bottom contains not only raw materials but also a large number of balls. The presence of numerous balls greatly increases the probability of collisions between them, thus accelerating ball wear and failing to improve the impact crushing effect of the falling balls on the raw materials. According to current technology, the energy efficiency of existing ball mills is only about 2%. Therefore, the overall working efficiency and energy utilization rate of existing ball mills are extremely low.

[0004] Therefore, we propose a ball rolling device for ceramic powder. Summary of the Invention

[0010] In a preferred embodiment, one end of the air duct is fixedly connected to the top of the feed pipe, one end of the threaded conveying rod inside the feed pipe is fixedly connected to the output shaft of the second motor, and the end of the feed pipe located inside the outer cylinder is fixedly connected to the connecting structure.

[0011] In a preferred embodiment, the ring body is hollow inside, and a feeding slot is provided below the top of the ring body. The outer cylinder is provided with an annular track adapted to the positioning track groove, and the track is provided with balls.

[0017] The present invention has the following beneficial effects:

[0018] 1. This ball rolling device for ceramic powder, through the combined use of a fixed ring and a connecting structure, allows the balls used for crushing and grinding to fall to the bottom of the outer cylinder and then roll along the inclined surface of the inner liner ring to both sides of the inner liner ring. The rings on both sides have feed ports, allowing the balls to roll into the feed ports. The rotation of the evenly distributed rotating ring lifts the balls to the top of the ring before they fall. This greatly reduces the number of balls accumulating at the bottom of the outer cylinder, thereby significantly reducing ineffective collisions between the balls and improving their service life.

[0019] 2. This ball-rolling device for ceramic powder has a screening structure at the top of the fixed ring. The rotation of the connecting structure drives the ceramic powder and the rolling balls to the top. After separation by the screening structure, the rolling balls roll back into the outer cylinder. The crushed ceramic powder is screened by the screening structure, and the powder that meets the screening particle diameter is filtered and separated into the next stage crushing chamber. The powder that does not meet the screening particle diameter will return to the current crushing chamber for further crushing. This process repeats, allowing each stage of the crushing chamber to effectively crush ceramic powder of different particle sizes. This avoids the need for the device to crush all the ceramic powder poured into the outer cylinder to the required particle size before unloading. This device allows the powder that meets the requirements to be separated and unloaded in advance without affecting the crushing of the powder that does not meet the requirements, greatly improving the efficiency of the device.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The ball rolling device for ceramic powder involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-4 A ball rolling device for ceramic powder includes an outer cylinder 1. A ring tooth 2 is fixedly installed at one end of the outer surface of the outer cylinder 1. A discharge port is opened at the end of the outer cylinder 1 where the ring tooth 2 is located. A drive gear 3 meshes with the ring tooth 2. A first motor 4 is fixedly connected to one side of the drive gear 3. A feed pipe 5 is movably installed at one end of the outer cylinder 1. A threaded conveying rod is provided inside the feed pipe 5. The end of the outer cylinder 1 with the feed pipe 5 is fixedly installed on a vertical rod. The other end of the outer cylinder 1 and the first motor 4 are movably installed on the vertical rod. The vertical rod is located at... A support frame 6 is fixedly installed on one side of the feed pipe 5. A fan 7 is fixedly installed at the end of the support frame 6. A duct 8 is fixedly installed at one end of the fan 7. A feed hopper 9 is fixedly installed at one end of the feed pipe 5. A second motor 10 is fixedly installed on one side of the feed hopper 9. Inner lining rings 11 are evenly fixedly installed on the inner surface of the outer cylinder 1. Fixed rings 12 are movably arranged inside the outer cylinder 1 on both sides of each inner lining ring 11. A connecting structure 13 is fixedly installed in the middle of the inner cylinder 1. A screening structure 14 is fixedly installed on the fixed ring 12.

[0030] Compared with the prior art, this application, through the combined use of the fixed ring 12 and the connecting structure 13, allows the grinding balls, after falling to the bottom of the outer cylinder 1, to roll along the inclined surface of the inner lining ring 11 to both sides of the inner lining ring 11. The ring bodies 121 on both sides have feed inlets 123, allowing the grinding balls to roll into the feed inlets 123. The rotation of the evenly distributed rotating ring 134 lifts the grinding balls to the top of the ring body 121 before they fall again. This significantly reduces the number of grinding balls accumulating at the bottom of the outer cylinder 1, thereby greatly reducing ineffective collisions between the grinding balls and improving their service life. Simultaneously, by providing a screening structure 14 at the top of the fixed ring 12, the rotation of the connecting structure 13 carries the ceramic powder and grinding balls to the top, where they pass through the screen. The separation process of the screening structure 14 involves the rolling ball rolling from the top of the screening structure 14 back into the outer cylinder 1. The crushed ceramic powder is then screened by the screening structure 14, with powder that meets the screening particle diameter being filtered and separated into the next stage of the crushing chamber. Powder that does not meet the screening particle diameter will return to the current crushing chamber for further crushing. This process repeats, allowing each stage of the crushing chamber to effectively crush ceramic powder of different particle sizes. This avoids the need for the device to crush all the ceramic powder poured into the outer cylinder 1 to the required particle size before unloading. The device allows the powder that meets the requirements to be separated and unloaded in advance without affecting the crushing of the powder that does not meet the requirements, greatly improving the efficiency of the device.

[0031] Please see Figure 2-3 A ball rolling device for ceramic powder includes an air duct 8, one end of which is fixedly connected to the top of a feed pipe 5, one end of a threaded conveying rod inside the feed pipe 5 is fixedly connected to the output shaft of a second motor 10, and one end of the feed pipe 5 located inside the outer cylinder 1 is fixedly connected to a connecting structure 13.

[0032] In this embodiment, it should be noted that when the raw material is conveyed by the threaded conveying rod in the feed pipe 5, the fan 7 can be used to generate air force at the same time. The air force helps the material flow in the feed pipe 5 until it enters the connecting structure 13. This not only increases the feeding effect, but also allows the raw material to be separated from the connecting structure 13 to the next level after being finely ground inside, thus improving the separation effect.

[0033] Please see Figure 4 and Figure 6A ball rolling device for ceramic powder includes a fixed ring 12, which comprises two ring bodies 121. The outer ring surface of the two ring bodies 121 is provided with a positioning groove 122. The bottom opposite surfaces of the two ring bodies 121 are provided with a feed port 123. The top of the ring bodies 121 is provided with a discharge port 124 above the location of the connecting structure 13. The lower side of the two outermost ring bodies 121 inside the outer cylinder 1 is fixedly installed with counterweights 125 respectively.

[0034] In this embodiment, it should be noted that the interior of the ring 121 is hollow, and a feeding slot is provided below the top of the ring 121. The outer cylinder 1 is provided with an annular track that matches the positioning rail slot 122, and the track is provided with balls. During the rotation of the outer cylinder 1, the ring 121 always keeps the counterweight 125 at the lowest end. The diameter of the feed inlet 123 is greater than or equal to twice the diameter of the balls used for crushing. In this way, the counterweight 125 can be used in combination with the annular track to ensure that the fixed ring 12 does not rotate significantly when the outer cylinder 1 rotates. This ensures that the screening structure 14 is always at the top for screening ceramic powder, and also ensures that the balls can smoothly enter the interior of the ring 121 through the feed inlet 123. This reduces the probability of collision between the balls and improves the service life of the balls.

[0035] Please see Figure 3-6 A ball rolling device for ceramic powder includes a connecting structure 13, the connecting structure 13 includes a central tube 131, a first connecting support rod 132 is fixedly installed at both ends of the central tube 131, a second connecting support rod 133 is uniformly fixedly installed on the outer surface of the central tube 131, and an evenly distributed rotating ring 134 is fixedly installed at the end of the second connecting support rod 133.

[0036] In this embodiment, it should be noted that the central tube 131 is hollow, the first connecting support rod 132 is fixedly connected to the inner surface of the outer cylinder 1, the second connecting support rod 133 is fixedly installed with a toggle end block, the evenly distributed rotating ring 134 is located in the internal cavity of the ring body 121, the evenly distributed rotating ring 134 is evenly provided with baffles and forms a sealed space with the inside of the ring body 121, so that the ceramic powder and the rolling balls located on the inner lining ring 11 at the bottom of the outer cylinder 1 can flow into the baffles of the evenly distributed rotating ring 134, and the ring body 121 can be used to convey the powder and rolling balls upward, so that the rolling balls fall after reaching the top to crush the powder below, and the crushed powder can be screened by the screening structure 14.

[0037] Please see Figure 2 A ball rolling device for ceramic powder includes an inner liner ring 11, the cross-sectional shape of the inner liner ring 11 is a circular arch, and the arched part is located in the middle of the inner liner ring 11.

[0038] In this embodiment, it should be noted that this allows the ceramic powder inside the outer cylinder 1 to be dispersed to both sides on the arched inner liner ring 11, and the rolling balls can also roll to both sides along the inclined surface after falling and breaking the ceramic powder, avoiding excessive accumulation of rolling balls in the middle that would cause collisions between the rolling balls. Furthermore, the rolling balls are collected by the connecting structure 13, rotate upwards, and then fall down, improving the working efficiency of the entire device.

[0039] Please see Figure 6-7 A ball rolling device for ceramic powder includes a sieving structure 14, which includes a holding frame 141. The holding frame 141 is convex in shape and has an open top. A dividing plate 142 is uniformly fixedly installed inside the larger opening of the convex-shaped holding frame 141. A rotating blade 143 is movably installed inside the holding frame 141. A spring 144 is fixedly installed inside the smaller opening of the holding frame 141. A first sieve plate 145 is fixedly installed at the top of the spring 144. A second sieve plate 146 is fixedly installed at the bottom of the holding frame 141. A guide plate 147 is fixedly installed at the bottom of the second sieve plate 146. An inclined block 148 is uniformly movably installed at one end of the guide plate 147.

[0040] In this embodiment, it should be noted that the gaps between the dividing plates 142 and between the dividing plates 142 and the holding frame 141 are larger than the diameter of the rolling ball. The first sieve plate 145 is located directly below the top of the ring body 121. The first sieve plate 145 is inclined towards the side where the rotating blade 143 is located, and the end away from the spring 144 is hinged to the holding frame 141. The second sieve plate 146 and the guide plate 147 are both located directly below the first sieve plate 145. The holding frame 141 is located at the bottom end of the upper first sieve plate 145, and sieve holes are opened on the first sieve plate 145 itself and the second sieve plate 146. The sieve holes on the first sieve plate 145 are... The diameter of the first sieve plate 145 is larger than the diameter of the sieve holes of the second sieve plate 146. The second sieve plate 146 is inclined toward the side where the container frame 141 is located. The guide plate 147 is also inclined in the opposite direction to the inclination of the second sieve plate 146. The diameter of the sieve holes of the first sieve plate 145 gradually decreases from one end where the feed hopper 9 is located to the other end. The inclined block 148 is hinged to the end of the guide plate 147, and a spring is installed in the hinged part. The end of the inclined block 148 is attached to the bottom end of the discharge port 124. In this way, when the evenly distributed rotating ring 134 conveys the powder and the rolling balls to the top of the first sieve plate 145, they will fall onto the first sieve plate 145 at the discharge trough of the ring body 121. Under the combined force of the rolling balls and the ceramic powder, the first sieve plate 145 compresses the spring 144, causing the first sieve plate 145 to bounce and vibrate. This not only allows the rolling balls to roll from the first sieve plate 145 towards the rotating blade 143, driving the blade 143 to rotate, but also causes the rolling balls to randomly roll off one end of the dividing plate 142 and exit the container frame 141, falling onto the powder inside the outer cylinder 1 for impact crushing. Simultaneously, the powder undergoes preliminary sieving as it bounces through the first sieve plate 145. This bouncing also prevents the powder from clogging the sieve holes of the first sieve plate 145, ensuring its continued use. The sieved powder then falls onto the second sieve plate 14. Powder particles larger than those on the second sieve plate 146 will roll down along the second sieve plate 146 back into the outer cylinder 1 for further crushing. The remaining particles, after being screened by the second sieve plate 146, will flow along the surface of the guide plate 147 to the next stage ring 121 for further crushing. This achieves automatic screening of qualified-sized powder without affecting the normal crushing of the remaining powder, greatly improving the continuity and efficiency of the device. The inclined blocks 148 will rotate downward one by one under the action of the rotating end block of the second connecting support rod 133, thus ensuring that the normal conveying of powder on the guide plate 147 to the next stage does not affect the rotation of the connecting structure 13.

[0041] Working principle: The ceramic powder to be crushed is poured into the feed hopper 9. When the device is started, the second motor 10 drives the threaded conveying rod inside the feed pipe 5 to rotate, conveying the powder into the outer cylinder 1. At the same time, the airflow generated by the blower 7 also enters the outer cylinder 1 through the threaded conveying rod to assist in the feeding and screening of raw materials. Under the drive of the first motor 4, the drive gear 3 is driven to rotate, thereby driving the ring gear 2 to rotate, so the outer cylinder 1 rotates accordingly.

[0042] During rotation, the ceramic powder and rolling balls are dispersed into the inner rings 121 on both sides by the inner lining ring 11. Under the rotation of the evenly distributed rotating ring 134, the ceramic powder and rolling balls rotate along the inside of the ring 121 and are conveyed to the top. They are then discharged from the top discharge chute onto the upper surface of the first sieve plate 145. This exerts a force on the spring 144, causing the first sieve plate 145 to rotate and bounce. Particles larger than the diameter of the sieve holes on the first sieve plate 145 will bounce towards the inner rings. The rotating blade 143 rolls in the same direction as the rolling ball, which crushes the powder. After impacting the rotating blade 143, the rotating blade 143 rotates, thus randomly discharging the powder and rolling ball from one end of the dividing plate 142. The powder and rolling ball fall back into the outer cylinder 1, where the rolling ball crushes the powder inside the outer cylinder 1. After impacting the ceramic powder, the falling rolling ball rolls along the inner lining ring 11 to both sides and enters the ring 121 again, thus repeating the cycle to crush the ceramic powder.

[0043] Powder with a particle size smaller than the first sieve plate 145 will fall onto the upper surface of the second sieve plate 146. Then, the powder with the required particle size will be screened by the second sieve plate 146 and sent to the guide plate 147 for conveying to the next stage of the fixed ring 12. Powder that does not meet the particle size requirements will return to the outer cylinder 1 on the surface of the spring 144 for further crushing. After multiple stages of crushing, the crushed ceramic powder will be continuously discharged from the outlet of the outer cylinder 1 due to the continuous screening action of the screening structure 14, thereby realizing the continuous crushing and collection of powder.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
