[0035] Next, some embodiments of the present application will be described in detail with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0036] Please refer to Figures 1-5, an embodiment of the present application provides an industrial waste residue secondary grinding device 100, which includes a cylinder body 10, abrasive 20, a motor 30, and a discharge port 40. Rolling shafts 13 are provided at both ends of the cylinder body 10, and a grinding chamber is provided. One end of the grinding chamber is provided with an inclined portion; the abrasive 20 is arranged in the grinding chamber; the motor 30 is arranged at one end of the cylinder body 10 away from the inclined portion for driving the cylinder body 10 to rotate; the discharge port 40 is arranged at one end of the grinding chamber close to the inclined portion. A spiral baffle 41 is provided at the discharge port 40. The spiral baffle 41 is annularly arranged on the inner surface of the discharge port 40. One end of the inclined portion is arranged on the cylinder body 10, and the other end is inclinedly arranged on the discharge port 40 to prevent materials from accumulating at the discharge port 40 during discharging.
[0037] Specifically, the cylinder body 10 is the main body of the entire device. The rolling shafts 13 support the rotation of the cylinder body 10 through the bearing seats 50 at both ends. The grinding chamber provides a dedicated space for the secondary grinding of waste residues, and the inclined portion is used to guide the materials to flow in a specific direction. A stable working platform is provided. Through the design of the inclined portion, the material flow direction is optimized, which helps to improve the stability and grinding efficiency of the device. The discharge port is used to discharge the ground materials. The spiral baffle 41 is arranged on the inner surface of the discharge port 40 to prevent materials from accumulating at the discharge port 40. It ensures the smooth discharge of materials, avoids the accumulation problem at the discharge port 40, and improves the stability and reliability of the device. The ground materials are guided at the inclined discharge port 40, and the spiral baffle 41 prevents the materials from forming a pile at the discharge port 40, ensuring the smooth discharge of materials.
[0038] Preferably, the abrasive 20 is composed of steel balls and steel segments. When changing the size and quantity of the abrasive 20 under the condition of constant total weight and comparing it with the abrasive 20 of the existing grinding device, the following conclusions can be obtained:
[0039] Existing abrasive 20:
[0040]
[0041]
[0042] Improved abrasive 20:
[0043]
[0044] Taking the preliminarily ground industrial waste residue as raw material, the specific surface area of the industrial waste residue after preliminary grinding is between 400 m2 / kg and 500 m2 / kg. When further grinding with an existing ball mill, the increase in specific surface area per 1 h is only 100 m2 / kg, still unable to meet the requirements of the specific surface area of ultrafine powder, and the energy consumption for grinding for 1 h is huge. After improvement, after adjusting the size and gradation, the total amount of steel balls and steel forgings increases, the weight remains unchanged, the overall voids decrease, and the grinding efficiency improves. According to experimental data, for grinding for 30 min, the material with a specific surface area of 400 m2 / kg can be ground to a specific surface area of more than 650 m2 / kg, greatly improving the test efficiency and reducing the processing energy consumption.
[0045] In a specific embodiment, the cylinder body 10 includes two bearing seats 50, the two bearing seats 50 are arranged at both ends of the cylinder body 10, and the rolling shafts 13 are respectively arranged on the two bearing seats 50.
[0046] Specifically, the bearing seat 50 provides a structure for supporting and fixing the bearing, supporting the movement of the entire rolling shaft 13 and the cylinder body 10. It improves the structural strength of the device and makes the entire system more stable. The rolling shaft 13 is placed on the two bearing seats 50 to achieve rotational movement between the bearing seats 50, driving the operation of the entire grinding system. It ensures the smooth rotation of the rolling shaft 13, reduces the vibration and friction of the rolling shaft 13, and helps to improve the working efficiency and service life of the device.
[0047] Furthermore, the motor 30 provides power to drive the rolling shaft 13 to rotate on the two bearing seats 50. The rotation of the rolling shaft 13 pushes the abrasive 20 in the grinding cavity to grind the industrial waste residue. The arrangement of the bearing seats 50 ensures the smooth movement of the rolling shaft 13 during rotation, reducing the vibration caused by uneven force. This design is suitable for grinding work that requires long-term and high-frequency operation, such as the secondary grinding of industrial waste residue in cement production. Through the reasonable arrangement of the bearing seats 50, the device can work stably, reducing the frequency of maintenance and replacement of parts, improving the reliability of the device, and being suitable for long-cycle production work.
[0048] In a specific embodiment, a rolling part 51 is provided on the bearing seat 50, and the rolling part 51 is arc-shaped and fits onto the rolling shaft 13.
[0049] Specifically, the rolling part 51 is a part of the bearing seat 50, used to come into contact with the rolling shaft 13, playing a role of support and guidance. It provides a larger contact area, reduces the friction between the bearing and the rolling shaft 13, and at the same time enhances the support ability. The arc-shaped design of the rolling part 51 ensures its fit with the rolling shaft 13, enabling the rolling shaft 13 to rotate on it. Through the arc-shaped fit, the friction between the bearing and the rolling shaft 13 is reduced, the working efficiency of the system is improved, and the energy loss is reduced at the same time.
[0050] Furthermore, during operation, the rolling shaft 13 rotates on the rolling part 51, and the arc surface of the rolling part 51 is in close contact with the rolling shaft 13, forming effective support and guidance. This helps to reduce friction, lower wear, and ensure the stable operation of the system. This design is applicable to devices that require long-term operation and high-frequency use, such as the industrial waste residue secondary ball milling device. By adopting the rolling part 51 with arc-shaped fitting, the system can operate more stably, reducing energy loss and mechanical wear, and improving the lifespan and performance of the device.
[0051] In a specific embodiment, the rolling shaft 13 further includes a connecting block 131, the connecting block 131 is sleeved on the rolling shaft 13, and the connecting block 131 is engaged with the rolling part 51.
[0052] Specifically, the connecting block 131 is an additional component on the rolling shaft 13, integrally formed with the rolling shaft 13, and is used to connect with the rolling part 51. It provides additional support for the rolling part 51 and ensures the firmness of the connection during the actuation process. The connecting block 131 is sleeved on the rolling shaft 13, ensuring that the connecting block 131 moves together with the rotation of the rolling shaft 13. It makes the connecting block 131 and the rolling shaft 13 form a whole, ensuring their coordinated work during operation and avoiding instability caused by relative sliding. The connecting block 131 is engaged with the rolling part 51 to achieve the connection with the rolling part 51, ensuring their coordinated movement. It provides additional fixed support, enhances the firmness of the connection, and reduces friction and vibration during movement.
[0053] Furthermore, during operation, the connecting block 131 moves together with the rotation of the rolling shaft 13, and the engagement of the connecting block 131 with the rolling part 51 ensures their synchronous work during rotation, guaranteeing the coordination of the system. This design is applicable to devices with high precision requirements, such as the industrial waste residue secondary ball milling device. Through the design of the connecting block 131, the system can operate more stably, reducing the relative friction between components, lowering the wear of the system, and improving the reliability and lifespan of the device.
[0054] In a specific embodiment, the connecting block 131 and the rolling shaft 13 are integrally formed.
[0055] Specifically, the connecting block 131 and the rolling shaft 13 are integrally formed, that is, both are formed together from the same material during the manufacturing process without the need for later assembly. This improves the integrity and stability of the structure, reduces the contact surfaces between components, and decreases the vibration and friction of the device. Since the connecting block 131 and the rolling shaft 13 are integrally formed, they have been tightly bonded during the manufacturing process. During operation, the two work together in a more unified manner, reducing the motion instability caused by seams or improper assembly. This integrally formed design is applicable to devices with high requirements for structural compactness and vibration control, such as in the industrial waste residue secondary ball milling device that requires high precision. Through integral forming, the looseness and deformation of the structure are reduced, and the working precision and reliability of the device are improved.
[0056] In a specific embodiment, the rolling shaft 13 further includes a plurality of fixing plates 132. One ends of the plurality of fixing plates 132 are arranged on the rolling shaft 13, and the other ends are arranged on the cylinder body 10. The plurality of fixing plates 132 surround the rolling shaft 13.
[0057] Specifically, the fixing plates 132 are arranged on the rolling shaft 13, fixing the relative position between the rolling shaft 13 and the cylinder body 10, and at the same time playing a role of support and fixation. The motion trajectory of the rolling shaft 13 is stabilized, and the vibration and sway of the rolling shaft 13 are reduced. One end of the fixing plate 132 is connected to the rolling shaft 13, and the other end is connected to the cylinder body 10, ensuring the coordinated movement between the fixing plate 132, the rolling shaft 13, and the cylinder body 10. A more firm connection between the rolling shaft 13 and the cylinder body 10 is provided, ensuring the stability of the system. The plurality of fixing plates 132 are distributed around the rolling shaft 13, jointly fixing the relative position between the rolling shaft 13 and the cylinder body 10, and preventing the deviation of the rolling shaft 13. The firmness of the connection is increased, and the swing and deviation that may occur during the operation of the device are reduced.
[0058] Furthermore, during operation, the plurality of fixing plates 132 ensure that the rolling shaft 13 maintains a constant relative position with the cylinder body 10 while rotating, maintaining the overall stability of the system. This design is applicable to occasions with relatively strict requirements for vibration and displacement, such as in the industrial waste residue secondary ball milling device that requires high precision and high stability. Through the arrangement of the plurality of fixing plates 132, the system can operate more reliably, improving the working precision and stability of the device.
[0059] In a specific embodiment, the grinding device further includes a buffer layer 60. The buffer layer 60 is arranged in the grinding cavity and is attached to the inner surface of the cylinder body 10 for absorbing the impact between the abrasive 20 and the cylinder body 10 during grinding.
[0060] Specifically, the buffer layer 60 is installed in the grinding cavity. Its main purpose is to absorb and mitigate the impact force generated during the grinding process. This improves the wear resistance of the system, reduces the loss of components within the grinding cavity, and extends the lifespan of the equipment. The buffer layer 60 is in direct contact with the inner surface of the grinding cavity, fitting within the cylinder 10 to form a layer of soft protection that reliably absorbs impacts. This reduces the direct collision between the abrasive 20 and the cylinder 10 during the grinding process, slows down wear, and improves the stability of the device.
[0061] Furthermore, during the grinding process, when the abrasive 20 interacts with the cylinder 10, the buffer layer 60 undertakes the task of absorbing impacts, avoiding direct metal-to-metal collisions. This design is suitable for scenarios with high requirements for equipment loss, such as in the industrial waste secondary ball milling device. Through the setting of the buffer layer 60, the system can better withstand impact forces during long-term operation, reduce wear, and extend the service life of the equipment.
[0062] In a specific embodiment, the buffer layer 60 is made of rubber.
[0063] Specifically, the rubber buffer layer 60 can provide a more significant impact absorption effect during the grinding process, reducing the impact force transmission between the abrasive 20 and the cylinder 10. During the grinding process, when the abrasive 20 collides with the cylinder 10, the rubber buffer layer 60 has high elasticity, can quickly deform to absorb impact energy, and then release the energy, reducing the impact on the entire system. This design is suitable for scenarios with high requirements for impact absorption performance, especially in the industrial waste secondary ball milling device where it is necessary to reduce the vibration and noise of the grinding equipment. By adopting the rubber buffer layer 60, the system can more effectively absorb impact energy, reduce noise generation, improve the comfort of the working environment, and at the same time reduce the maintenance cost of the equipment.
[0064] In a specific embodiment, the grinding device includes a feed inlet 14, and the feed inlet 14 is provided on the cylinder 10.
[0065] Specifically, the feed inlet 14 is a channel for introducing raw materials or industrial waste, guiding the material into the grinding cavity for the grinding process. It provides a convenient entrance, enabling the raw material to smoothly enter the grinding cavity and participate in the grinding process. The feed inlet 14 is directly set on the cylinder 10, facilitating the direct feeding of the material, reducing the material transmission path and possible resistance. This simplifies the material introduction process and improves the operation convenience and efficiency.
[0066] In a specific embodiment, the grinding device further includes a speed reducer 70. One end of the speed reducer 70 is connected to the drive shaft of the motor 30, and the other end is connected to the rolling shaft 13, for increasing the torque required for rotation.
[0067] Specifically, the speed reducer 70 is a mechanical transmission device that adapts to the rotational requirements under different working conditions by reducing the rotational speed of the output shaft and increasing the torque of the output shaft at the same time. The torque output of the system is increased, enabling the equipment to more easily handle large particles or difficult-to-grind materials during the grinding process. The motor 30 transmits power to the speed reducer 70 through the drive shaft. The speed reducer 70 converts the high-speed and low-torque power into a low-speed and high-torque output through internal gear transmission, and finally provides a high-torque rotational force for the grinding device through the connection with the rolling shaft 13.
[0068] The above are only the embodiments of the present application. It should be noted here that for those of ordinary skill in the art, improvements can be made without departing from the creative concept of the present application, but these all fall within the protection scope of the present application.
