Description

Technical Field

[0001] This utility model relates to the field of zinc oxide processing technology, specifically a zinc oxide grinding machine. Background Technology

[0002] In the chemical production field, zinc oxide, as an important inorganic chemical raw material, is widely used in many industries such as rubber, coatings, electronics, and pharmaceuticals. Grinding is a crucial step in the production and processing of zinc oxide, its purpose being to grind the raw material to a suitable particle size to meet the particle size requirements of different applications.

[0003] Currently, there are many types of zinc oxide grinding equipment on the market, but in actual use, some obvious defects and shortcomings still exist. In terms of grinding efficiency, traditional zinc oxide grinding mills mostly use a single grinding method and a simple grinding structure. The contact area between the grinding media and the zinc oxide material is limited, and the collision frequency is low, resulting in a slow grinding process. It is difficult to grind zinc oxide to the required fineness in a short time, resulting in low production capacity. Regarding unloading, existing unloading methods usually simply discharge the ground material without effective control and processing of the unloading process. Incomplete unloading often occurs, not only wasting material but also making it difficult to guarantee the uniformity and fineness of the unloaded material, affecting product quality.

[0012] This utility model relates to a zinc oxide grinding machine, which has significant advantages and positive effects compared with the prior art, specifically reflected in the following aspects:

[0013] 1. Significantly improved grinding efficiency:

[0014] This invention employs a dual-grinding-ball design (grinding ball one and grinding ball two), significantly increasing the contact area and collision frequency between the grinding media and the zinc oxide material. The uniformly distributed protrusions on the outer side of grinding ball one match the uniformly distributed grooves on the outer side of grinding ball two, further optimizing the interaction between the grinding media and making the grinding process more efficient. Within the same time frame, zinc oxide can be ground to a finer particle size, thereby significantly improving production capacity.

[0015] The guide plates evenly arranged inside the inner cylinder enable the material and grinding media to mix and move fully, avoiding dead zones in the grinding process and further improving grinding efficiency.

[0016] 2. Secondary grinding during unloading:

[0017] The spiral agitator inside the discharge cylinder works in conjunction with the fine grinding blocks on the inner wall of the cylinder to perform secondary grinding of the material during the discharge process. This design not only ensures the uniformity and fineness of the material, but also avoids material waste caused by incomplete discharge, thereby improving the utilization rate of the material.

[0018] 3. Enhanced structural stability:

[0019] The reinforcing rods evenly arranged on the side wall of the inner cylinder and the screens fixed between adjacent reinforcing rods enhance the structural stability of the inner cylinder and prevent deformation or damage to the inner cylinder caused by high-speed rotation and collision during the grinding process.

[0020] The annular support grooves on the inner wall of the ball mill chamber, corresponding to the roller positions, allow the rollers to extend into the annular support grooves, further improving the support and stability of the inner cylinder and extending the service life of the equipment.

[0021] 4. Improved ease of operation and degree of automation:

[0022] The controller located on the outside of the outer casing is connected to the servo motor and the unloading motor, which realizes automated control of the grinding process, simplifies the operation process, reduces human operation errors, and improves production efficiency and safety.

[0023] The design of the feed hopper extending into the inner cylinder through the guide pipe makes the feeding process smoother and avoids spillage and waste of materials during the feeding process.

[0024] 5. Significant environmental protection and energy-saving effects:

[0025] Due to the improved grinding efficiency, the energy consumption required by this invention is significantly reduced under the same production capacity, achieving the effect of energy saving.

[0026] The efficient grinding and unloading process reduces material residue and waste, lowers waste emissions during production, and has significant environmental benefits.

[0027] 6. The equipment is easy to maintain and clean:

[0028] The support base plate, which is fixed to the outside of the unloading cylinder by columns, makes the equipment easier to maintain and clean, reduces downtime, and improves the overall utilization rate of the equipment.

[0029] The design of the discharge pipe makes the unloading process smoother, and facilitates material collection and equipment cleaning.

[0030] In summary, this novel zinc oxide grinding machine, through its innovative design and technical solutions, significantly improves grinding efficiency, enhances equipment stability, increases ease of operation and automation, while also exhibiting significant environmental and energy-saving effects.

[0049] The blades of the spiral agitator 11 are arranged in a spiral shape, and fine grinding blocks 25 are provided on the inner wall of the discharge cylinder 4 between adjacent blades.

[0050] During rotation, the spiral agitator 11 not only agitates the materials but also grinds them using the fine grinding blocks 25.

[0051] Fine grinding blocks 25 are fixed on the inner wall of the unloading cylinder 4, and one block is set between the blades of adjacent spiral agitators 11.

[0052] The fine grinding block 25 is made of high-hardness material with a smooth surface, which can effectively grind zinc oxide materials and improve grinding efficiency.

[0053] The support base plate 1 is fixed to the bottom outer side of the outer casing 5 by evenly arranged columns 10.

[0054] The base plate 1 is used to support the weight of the entire grinding machine and maintain the stability of the equipment.

[0055] The discharge pipe 3 is located at the bottom of one side of the discharge cylinder 4 and is used to discharge the ground zinc oxide material.

[0056] A conveying device can be connected to the outlet of the discharge pipe 3 to facilitate the collection and transportation of materials.

[0057] A servo motor 6 is installed on one side of the outer casing 5, and the output end of the servo motor 6 extends into the ball mill chamber 13 of the outer casing 5 and is installed with an inner cylinder 19. A feed hopper 8 is provided on the other side of the outer casing 5. The output end of the feed hopper 8 extends into the inner cylinder 19 through a guide pipe 15. Grinding balls 1 20 and grinding balls 21 are evenly arranged inside the inner cylinder 19. Protrusions 17 are evenly arranged on the outer side of grinding balls 1 20, and grooves 18 are evenly arranged on the outer side of grinding balls 21. The volume of the protrusions 17 and the depth of the grooves 18 are matched.

[0058] The outer casing 5 is made of high-strength steel, which has good wear resistance and corrosion resistance. A servo motor 6 is fixedly installed on one side wall of the outer casing 5. The servo motor 6 is a high-precision, high-torque model to ensure the stability and efficiency of the ball milling process. The output end of the servo motor 6 is connected to the drive shaft of the inner cylinder 19 through a coupling, and the output end extends into the ball mill chamber 13 of the outer casing 5.

[0059] The inner cylinder 19, located inside the ball mill chamber 13, is made of wear-resistant material and has a smooth inner wall to reduce material adhesion during the grinding process. The inner cylinder 19 is supported by bearings on the inner wall of the outer casing 5 and can rotate around its axis. A servo motor 6 drives the inner cylinder 19 to rotate, thereby enabling the grinding balls inside to perform efficient grinding operations.

[0060] A feed hopper 8 is located on the other side of the outer casing 5. The feed hopper 8 is designed with an incline to allow materials to slide down smoothly. The output end of the feed hopper 8 extends into the inner cylinder 19 through a guide pipe 15. The guide pipe 15 is made of a flexible material to adapt to the rotational movement of the inner cylinder 19, ensuring that materials enter the inner cylinder 19 evenly.

[0061] The inner cylinder 19 is uniformly equipped with grinding balls 20 and 21. Grinding balls 20 have uniformly distributed protrusions 17 on their outer sides, which effectively improve grinding efficiency and increase the contact area between the material and the grinding balls. Grinding balls 21 have uniformly distributed grooves 18 on their outer sides, the depth of which matches the volume of the protrusions 17, allowing grinding balls 20 and 21 to fit together tightly during rotation, resulting in highly efficient grinding.

[0062] The inner cylinder 19 is also uniformly provided with reinforcing rods 23 on its side wall, and screens 24 are fixed on the side wall of the inner cylinder 19 between adjacent reinforcing rods 23. Furthermore, guide plates 7 are uniformly provided inside the inner cylinder 19.

[0063] A feed inlet 22 for the guide pipe 15 to pass through is provided at the center of one side of the inner cylinder 19, and rollers 16 are evenly arranged in a ring at the edge of the inner cylinder 19 outside the feed inlet 22.

[0064] The inner cylinder 19 is the core component of this device, and its side walls are made of high-strength materials to ensure the stability and durability of the device. Several reinforcing rods 23 are evenly arranged on the side walls of the inner cylinder 19. These reinforcing rods 23 not only enhance the structural strength of the inner cylinder 19, but also serve to support the screen 24.

[0065] The reinforcing rods 23 are made of metal and have high strength and rigidity. The reinforcing rods 23 are evenly distributed along the sidewall of the inner cylinder 19. The cross-sectional shape of the reinforcing rods 23 can be circular, square, or other suitable shapes to maximize their supporting effect.

[0066] The screen 24 is fixed to the side wall of the inner cylinder 19 between adjacent reinforcing rods 23. The screen 24 is made of a highly wear-resistant material, possessing excellent screening performance and durability. The mesh size of the screen 24 is selected according to the particle size requirements of the material to be screened to ensure effective screening. The screen 24 is fixed between the reinforcing rods 23 and the inner cylinder 19 by fasteners to ensure it does not loosen during operation.

[0067] Several guide plates 7 are evenly arranged inside the inner cylinder 19. The function of the guide plates 7 is to guide the material to be evenly distributed inside the inner cylinder 19, thereby improving screening efficiency. The guide plates 7 are made of lightweight, high-strength material, and their shape and arrangement are designed according to the flow characteristics of the material and screening requirements. The guide plates 7 are evenly distributed along the axial direction of the inner cylinder 19 and maintain a certain gap with the inner wall of the inner cylinder 19 to avoid material accumulation.

[0068] A feed inlet 22 is provided at the center of one side of the inner cylinder 19 for the material guide tube 15 to pass through. The design of the feed inlet 22 allows the material to enter the inner cylinder 19 smoothly. The diameter of the feed inlet 22 should be large enough to ensure that the material does not block the feed inlet 22.

[0069] A plurality of rollers 16 are evenly arranged in a ring around the edge of the inner cylinder 19 outside the feed inlet 22. The function of the rollers 16 is to support and stabilize the inner cylinder 19, enabling it to rotate smoothly during operation. The rollers 16 are made of wear-resistant material, and their bearings should have good lubrication performance to ensure flexible rotation. The rollers 16 are evenly distributed along the outer side of the feed inlet 22, and each roller 16 is connected to the inner cylinder 19 through a bearing, with the outer edge of the roller 16 in contact with the ground or other supporting surface.

[0070] An annular support groove 14 is provided on the inner wall of the ball mill chamber 13 at the position corresponding to the roller 16, and the roller 16 extends into the interior of the annular support groove 14. The bottom of the ball mill chamber 13 is also provided with a discharge port 12 connected to the input end of the discharge cylinder 4.

[0071] The ball mill chamber 13 has a cylindrical structure, and its inner wall is provided with an annular support groove 14 at the position corresponding to the roller 16. The depth and width of the annular support groove 14 are designed according to the size of the roller 16 to ensure that the roller 16 can be stably embedded in it, so that the roller 16 can rotate freely within the annular support groove 14.

[0072] The bottom of the ball mill chamber 13 is equipped with a discharge port 12. The diameter of the discharge port 12 is designed according to the material flow rate to ensure that the material can be discharged smoothly. The discharge port 12 is connected to the input end of the unloading cylinder 4 through a flange to ensure the sealing and stability of the connection. The output end of the unloading cylinder 4 is connected to the material collection system to complete the collection and transportation of materials.

[0073] The outer side of the outer casing 5 is also equipped with a controller 9 that is connected to the servo motor 6 and the unloading motor 2.

[0074] When this application embodiment is used,

[0075] During the feeding process, the zinc oxide material to be ground is poured into the feed hopper 8. Due to the inclined design of the feed hopper 8, the material naturally slides down under the action of gravity and enters the guide pipe 15. This ensures that the material can enter the inner cylinder 19 evenly and stably through the feed inlet 22.

[0076] The grinding process starts with the controller 9, which activates the servo motor 6, causing the inner cylinder 19 to rotate around its axis within the ball mill chamber 13. As the inner cylinder 19 rotates, the grinding balls 20 and 21 inside move accordingly. The protrusions 17 on the outer side of grinding ball 20 and the grooves 18 on the outer side of grinding ball 21 match each other. During rotation, the grinding balls collide, squeeze, and rub against each other and against the zinc oxide material. When the protrusions 17 embed into the grooves 18, the material is more effectively crushed and ground, increasing the contact area and effect between the grinding media and the material, thus improving grinding efficiency. The guide plate 7 inside the inner cylinder 19 guides the material to distribute evenly within the inner cylinder 19, preventing material accumulation or grinding dead zones, ensuring the material fully contacts the grinding balls, further improving the grinding effect. As grinding proceeds, zinc oxide material that meets the particle size requirements falls into the bottom of the ball mill chamber 13 through the screen 24 supported by reinforcing rods 23 on the side wall of the inner cylinder 19; material that does not meet the particle size requirements continues to be ground inside the inner cylinder 19.

[0077] During the unloading process, after the material in the inner cylinder 19 has been ground, the ground material enters the unloading cylinder 4 through the discharge port 12 at the bottom of the ball mill chamber 13. The discharge port 12 is connected to the input end of the unloading cylinder 4 via a flange, ensuring the sealing and stability of the connection and preventing material leakage. The unloading motor 2 is started, driving the spiral agitator 11 to rotate inside the unloading cylinder 4. While the spiral agitator 11 agitates the material, the material interacts with the fine grinding blocks 25 on the inner wall of the unloading cylinder 4, undergoing secondary grinding to further improve the fineness and uniformity of the material. After secondary grinding, the material is pushed by the spiral agitator 11 and discharged from the unloading cylinder 4 through the discharge pipe 3. The conveying device connected to the outlet of the discharge pipe 3 collects the material and transports it to a designated location, completing the unloading process.

[0078] After the grinding and unloading operations are completed, the servo motor 6 and the unloading motor 2 are stopped via controller 9. The equipment is then cleaned, including the feed hopper 8, guide pipe 15, inner cylinder 19, ball mill chamber 13, and unloading cylinder 4, to remove residual material and prevent blockage and corrosion. The wear condition of each component is checked, including grinding balls 20, grinding balls 21, screen 24, and fine grinding blocks 25. Severely worn components are replaced or repaired to ensure normal and efficient operation in the next run.

[0079] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
