Description

Technical Field

[0001] This invention relates to the field of grinding and processing, specifically to a grinding and pulverizing equipment for ultrafine tungsten oxide that can be recycled as waste, and its production process. Background Technology

[0002] In the production and processing of ultrafine tungsten oxide, the recycling of waste materials has always been a key concern in the industry. Traditional grinding and pulverizing equipment has many drawbacks when processing ultrafine tungsten oxide waste.

[0003] On the one hand, existing grinding equipment often cannot precisely control the grinding process, making it difficult to fully and uniformly grind tungsten oxide in waste materials to the required ultrafine particle size. This results in inconsistent quality of recovered tungsten oxide, failing to meet the stringent material requirements of high-end applications. On the other hand, most equipment lacks an effective waste separation and recycling mechanism. During the grinding process, the qualified ground material cannot be separated from the unground material in a timely manner, leading to over-grinding or under-grinding, which not only reduces production efficiency but also wastes a significant amount of energy.

[0004] Furthermore, traditional equipment cannot recover waste materials from ultrafine tungsten oxide during the grinding and pulverizing process. Most grinding equipment simply uses ball mills to thoroughly crush the waste materials. Since there is no waste recovery mechanism, traditional ball mills need to run continuously for extended periods to grind all materials until they all reach the finest particle size standard, which is time-consuming. In large-scale production scenarios, the time cost of processing waste per batch is high, and the amount of qualified ultrafine tungsten oxide that can be recovered per unit time is small, failing to meet the demands of efficient production. Moreover, the ground materials are all in a mixed state, containing qualified ultrafine tungsten oxide, larger particles that do not meet the standard, and over-ground particles. Subsequent complex screening and grading processes are required to separate qualified products, increasing production costs and the complexity of the production process.

[0005] Therefore, how to design an efficient, stable, and environmentally friendly ultrafine tungsten oxide waste recycling grinding and pulverizing equipment has become an urgent problem to be solved. Summary of the Invention

[0006] Therefore, it is necessary to provide a grinding and pulverizing equipment and its production process for ultrafine tungsten oxide that can be recycled from waste, addressing the existing technical problems.

[0007] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows:

[0008] A grinding and pulverizing device for recycling ultrafine tungsten oxide waste includes a ball mill cylinder and further includes:

[0009] A main gear ring is fixed to one end of the ball mill cylinder, and a secondary gear ring is located at the other end of the ball mill cylinder.

The middle part of the rotating shaft is fixedly connected to the rocker arm. The rotating shaft is fixedly connected to the auxiliary pulley on the same axis.

[0011] Furthermore, a bearing seat is fixed to the side of the rocker arm away from the center of the main seat. A limit shaft is rotatably mounted on the bearing seat. Limit grooves are formed in the circumferential direction of the main seat and the auxiliary seat. The two ends of the limit shaft are slidably connected to the corresponding limit grooves.

[0012] Furthermore, the leveling mechanism includes a balancing gear ring, a stabilizing gear, a connecting frame, and a balancing motor. The connecting frame is fixedly connected to the rocker arm, the balancing motor is fixedly connected to the connecting frame, the power supply provides power to the balancing motor, the stabilizing gear is connected to the output end of the balancing motor, the balancing gear ring is fixedly connected to the main frame on the same axis, and the balancing motor is electrically connected to the level sensor through a controller.

[0013] Furthermore, the leveling mechanism also includes an electromagnetic clutch, and the output end of the balancing motor is connected to the stabilizing gear transmission via the electromagnetic clutch.

[0014] Furthermore, a sub-frame is provided at the end of the ball mill cylinder away from the main gear ring. The sub-frame is fixedly connected to the rocker arm. A disk is provided at the end of the sub-frame closer to the secondary gear ring. A positioning disk is fixedly connected to the secondary gear ring on the same axis. The positioning disk and the disk are attracted by magnetic force. A transition pin is provided at the center of the positioning disk. The ball mill cylinder is connected to the secondary gear ring through a one-way bearing and the positioning disk. One end of the transition pin is fixedly connected to the positioning disk, and the other end is fixedly connected to the filter screen. The transition pin is rotatably connected to the ball mill cylinder.

[0015] Furthermore, the adjustment mechanism includes a limit plate frame, an electric actuator, a pressure regulating plate, and a secondary support plate. The limit plate frame is fixedly connected to the side of the main frame away from the center of the main seat. The fixed end of the electric actuator is fixedly connected to the limit plate frame. The output end of the electric actuator is fixedly connected to the pressure regulating plate. The secondary support plate is fixedly connected to the end of the filter plate near the electric actuator. The secondary support plate and the pressure regulating plate are rotatably connected coaxially.

[0016] Furthermore, two buffer shafts are arranged in an equidistant array along the circumference at the end of the main frame away from the ball mill cylinder. One end of the buffer shaft is fixedly connected to the main frame, and the other end is slidably connected to the auxiliary support plate. A tension spring is arranged coaxially on the outside of the buffer shaft. One end of the tension spring is fixedly connected to the main frame, and the other end is fixedly connected to the auxiliary support plate.

[0017] A production process for recycling ultrafine tungsten oxide waste also includes the following steps:

[0018] S1: The operator opens the feed port of the corresponding grinding chamber of the ball mill and slowly and evenly pours the waste material containing ultrafine tungsten oxide to be recycled into the grinding chamber;

[0019] S2: Start the device. The ball mill cylinder rotates along the circumference of the main seat. During this process, the material in the grinding chamber will pass through the filter screen and move into the receiving chamber.

[0020] S3: When the amount of material recovered in the containment chamber reaches the expected amount or the predetermined production task is completed, the operator shuts down the equipment and then discharges and collects the recovered ultrafine tungsten oxide material in the containment chamber.

[0021] S4: Operators clean the inside of the ball mill cylinder, grinding media, filter screen, filter plates and other components to remove residual materials and prepare for the next production run.

[0022] The beneficial effects of this invention compared to the prior art are:

[0023] Firstly, this equipment ensures that the filter screen remains horizontal throughout the grinding process through a horizontal holding mechanism, allowing the grinding media to grind the material evenly and avoiding over- or under-grinding in certain areas. This significantly improves the grinding quality of ultrafine tungsten oxide waste, resulting in more uniform tungsten oxide particle size that better meets the production needs of high-end products.

[0024] Secondly, the adjustment mechanism can precisely control the movement of the filter plate, so that the filter screen and filter plate pores are repeatedly aligned and staggered at a set frequency, and the qualified materials are transferred to the receiving cavity in a timely manner, avoiding over-grinding of qualified materials and premature outflow of unqualified materials, which greatly improves the recycling efficiency of ultrafine tungsten oxide waste.

[0025] Thirdly, the filter screen and the ball mill cylinder in this device can rotate relative to each other or synchronously, thereby realizing the recycling of waste materials during the grinding process, avoiding over-grinding of qualified materials, and preventing unqualified materials from flowing out prematurely, effectively improving the waste recycling efficiency, and significantly increasing the recycling volume per unit time compared with traditional equipment.

[0036] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0037] refer to Figures 1 to 8 A grinding and pulverizing device for recycling ultrafine tungsten oxide waste includes a ball mill cylinder 1, and further includes:

[0038] A main gear ring 2 is fixedly connected to one end of the ball mill cylinder 1, and a secondary gear ring 6 is disposed at the other end of the ball mill cylinder 1. The ball mill cylinder 1 is connected to the secondary gear ring 6 via a one-way bearing 5. A filter screen 31 is disposed inside the ball mill cylinder 1. One side of the filter screen 31 is a grinding chamber 3 containing several grinding media 41, and the other side is a receiving chamber 4 without grinding media 41. A filter plate 32 is slidably disposed in the middle of the filter screen 31 (e.g., a filter plate 32 is slidably disposed in the middle of the filter screen 31). Figure 5 As shown), the filter screen 31 has the same number of filter holes as the filter plate 32, and they correspond one-to-one (e.g., ...). Figure 5 As shown), a main seat 11 is provided on one side of the ball mill cylinder 1, and a secondary seat 21 is provided on the other side. A rocker arm 24 is rotatably mounted on the side of the main seat 11 closest to the secondary seat 21 (as shown). Figure 1 As shown), a power supply 25 is provided on the side of the rocker arm 24. The end of the rocker arm 24 near the ball mill cylinder 1 is rotatably connected to the ball mill cylinder 1. The main seat 11 is provided with a main arc tooth 12 that meshes with the main gear ring 2 on the side near the ball mill cylinder 1. The auxiliary seat 21 is provided with an auxiliary arc tooth 22 that meshes with the auxiliary gear ring 6 on the side near the ball mill cylinder 1. The end of the filter screen 31 away from the auxiliary gear ring 6 is fixedly connected to the main frame 13. The main frame 13 is rotatably connected to the ball mill cylinder 1. A level sensor 14 is provided on the main frame 13. A level holding mechanism 15 is provided on the side of the rocker arm 24 near the main frame 13. The level holding mechanism 15 is connected to the power supply 25 and electrically connected to the level sensor 14. An adjustment mechanism 28 that drives the filter plate 32 to move is provided on the side of the level holding mechanism 15.

[0039] When the device is in operation, the operator puts the material into the grinding chamber 3 of the ball mill cylinder 1 and then starts the equipment. At this time, the rocker arm 24 drives the ball mill cylinder 1 to move along the circumference of the main seat 11. When the main gear ring 2 meshes with the main arc tooth 12, the main gear ring 2 will drive the ball mill cylinder 1, which is fixed to it, to rotate. At this time, the filter screen 31 is kept horizontal under the action of the horizontal holding mechanism 15, and the grinding media 41 in the grinding chamber 3 grinds the material. The filter holes of the filter screen 31 and the filter holes of the filter plate 32 are staggered to prevent the material from being ground prematurely. The material flies into the receiving cavity 4. As the ball mill cylinder 1 moves, when the auxiliary gear ring 6 meshes with the auxiliary arc tooth 22, under the action of the one-way bearing 5, the rotation of the auxiliary gear ring 6 will drive the ball mill cylinder 1 and the filter screen 31 to rotate along the center direction of the ball mill cylinder 1. During this process, the adjustment mechanism 28 will drive the filter plate 32 to move, so that the filter holes of the filter screen 31 and the filter holes of the filter plate 32 are repeatedly aligned and staggered, thereby ensuring that the crushed material in the grinding cavity 3 can move into the receiving cavity 4, thereby realizing the recycling of waste ultrafine tungsten oxide.

[0040] In order to drive the rocker arm 24 to rotate, the following features are also provided:

[0041] The main motor 7 is located on the side of the auxiliary seat 21 (e.g., Figure 2 As shown, the main motor 7 is fixedly connected to the auxiliary seat 21 via a pad. A main pulley 8 is coaxially fixed to the output end of the main motor 7. An auxiliary pulley 9 is positioned above the main pulley 8, rotatably connected to the auxiliary seat 21 and driven by a belt to the main pulley 8. One end of the rotating shaft 10 is rotatably connected to the main seat 11, and the other end is rotatably connected to the auxiliary seat 21. The middle of the rotating shaft 10 is fixedly connected to the rocker arm 24, and the rotating shaft 10 is coaxially fixed to the auxiliary pulley 9. After the main motor 7 is powered on, it drives the auxiliary pulley 9 to rotate via the main pulley 8. The auxiliary pulley 9 then drives the rocker arm 24, which is fixedly connected to it, to rotate via the rotating shaft 10, thereby enabling the ball mill cylinder 1 to move along the circumference of the main seat 11.

[0042] In order to limit the movement of the rocker arm 24 and prevent excessive pressure on the rotating shaft 10, the following features are specifically designed:

[0043] A bearing seat 26 is fixed to the side of the rocker arm 24 away from the center of the main seat 11 (e.g.) Figure 2 As shown), a limit shaft 27 is rotatably provided on the bearing seat 26 (as shown). Figure 3 As shown, the main seat 11 and the auxiliary seat 21 are formed with limiting grooves 23 along the circumferential direction, and the two ends of the limiting shaft 27 are slidably connected to the corresponding limiting grooves 23. When the rocker arm 24 drives the ball mill cylinder 1 to move along the circumferential direction of the main seat 11, the two ends of the limiting shaft 27 slide in the corresponding limiting grooves 23. This effectively avoids the rocker arm 24 from deviating during the movement process, prevents the rotating shaft 10 from bearing excessive pressure, and ensures the stability and reliability of the entire device operation.

[0044] To further refine the specific structure of the horizontal holding mechanism 15, and to ensure that the filter screen 31 remains horizontal when the grinding media 41 in the ball mill 1 grinds the material, thereby preventing the material from prematurely passing through the filter screen 31 and moving to the other side of the ball mill 1, the following features are also provided:

[0045] The horizontal holding mechanism 15 includes a balancing gear ring 16, a stabilizing gear 17, a connecting frame 18, and a balancing motor 20. The connecting frame 18 is fixedly connected to the rocker arm 24 (e.g., Figure 3 As shown, the balancing motor 20 is fixedly connected to the connecting frame 18, the power supply 25 is fixedly connected to the connecting frame 18 and provides power to the balancing motor 20, the stabilizing gear 17 is driven by the output end of the balancing motor 20, the balancing gear ring 16 is coaxially fixedly connected to the main frame 13, and the balancing motor 20 is electrically connected to the level sensor 14 through a controller. After the balancing motor 20 starts, its output end drives the stabilizing gear 17 to rotate. The stabilizing gear 17 drives the balancing gear ring 16, which meshes with it, to rotate, thereby changing the angle of the main frame 13 to ensure that the filter screen 31 is in a horizontal state when the main frame 13 rotates relative to the grinding cylinder 1.

[0046] During the above process, the horizontal sensor 14 is used to detect the tilt angle of the filter screen 31. Then, the horizontal sensor 14 transmits this signal to the controller, and the controller controls the output power of the balancing motor 20 to ensure that the main frame 13 and the filter screen 31 connected thereto remain horizontal during the grinding process of the grinding media 41 grinding the material. That is, at this time, the material is only broken by the grinding media 41 in the grinding chamber 3, preventing the material from passing through the filter screen 31 in advance and moving to the other side of the ball mill cylinder 1.

[0047] To facilitate the timely disconnection and connection of the balancing motor 20 and the stabilizing gear 17 according to the processing stage, the following features are specifically provided:

[0048] The leveling mechanism 15 also includes an electromagnetic clutch 19. The output of the balancing motor 20 is connected to the stabilizing gear 17 via the electromagnetic clutch 19. When the stabilizing gear 17 and the balancing motor 20 need to work together to ensure that the filter screen 31 remains level, the electromagnetic clutch 19 is energized and engaged, allowing the power of the balancing motor 20 to be transmitted to the stabilizing gear 17, thus achieving the leveling function of the filter screen 31. During the processing stage when the stabilizing gear 17 does not need to work, the electromagnetic clutch 19 is de-energized and disengaged, and the balancing motor 20 is disconnected from the stabilizing gear 17. This prevents the balancing gear ring 16 from applying excessive torque to the balancing motor 20 through the stabilizing gear 17 due to the synchronous rotation of the filter screen 31 and the ball mill cylinder 1, which could ultimately damage the balancing motor 20.

[0049] To avoid excessive pressure on the electromagnetic clutch 19 caused by the rotation of the auxiliary gear ring 6 driven by the ball mill cylinder 1 when the main gear ring 2 meshes with the main arc gear 12, the following features are further provided:

[0050] A secondary frame 30 is provided at the end of the ball mill cylinder 1 away from the main gear ring 2. The secondary frame 30 is fixedly connected to the rocker arm 24. A disk 29 is provided at the end of the secondary frame 30 near the secondary gear ring 6. A positioning disk 40 is coaxially fixed to the secondary gear ring 6. The positioning disk 40 and the disk 29 are attracted by magnetic force. An adapter pin 39 is provided at the center of the positioning disk 40 (e.g., ...). Figure 5 As shown, the grinding cylinder 1 is connected to the auxiliary gear ring 6 via a one-way bearing 5 and a positioning disk 40. One end of the adapter pin 39 is fixed to the positioning disk 40, and the other end is fixed to the filter screen 31. The adapter pin 39 is rotatably connected to the grinding cylinder 1. When the main gear ring 2 meshes with the main arc tooth 12, the grinding cylinder 1 and the auxiliary gear ring 6 will rotate relative to each other because they are connected via a one-way bearing 5 and a positioning disk 40. However, to ensure that the auxiliary gear ring 6 does not rotate, the disk 29 limits the auxiliary gear ring 6 through the positioning disk 40. The adapter pin 39 ensures that when the auxiliary gear ring 6 meshes with the auxiliary arc tooth 22, the auxiliary gear ring 6 will drive the positioning disk 40. At the same time, the positioning disk 40 can also drive the grinding cylinder 1 to rotate via the one-way bearing 5. Simultaneously, the positioning disk 40 can also drive the filter screen 31 to rotate via the adapter pin 39. At this time, the filter screen 31 and the grinding cylinder 1 achieve synchronous displacement.

[0051] In order to achieve the offset and alignment of the filter holes on the filter plate 32 and the filter screen 31, the following features are specifically provided:

[0052] The adjusting mechanism 28 includes a limiting plate 36, an electric actuator 37, a pressure regulating plate 38, and a secondary support plate 33. The limiting plate 36 is fixedly connected to the side of the main frame 13 away from the center of the main seat 11 (e.g., Figure 4 As shown, the fixed end of the electric actuator 37 is fixedly connected to the limiting plate 36, and the output end of the electric actuator 37 is fixedly connected to the pressure regulating plate 38. The auxiliary support plate 33 is fixedly connected to the end of the filter plate 32 near the electric actuator 37, and the auxiliary support plate 33 is rotatably connected to the pressure regulating plate 38 along the same axis. When it is necessary to achieve the misalignment and alignment of the filter holes on the filter plate 32 and the filter holes on the filter screen 31, the electric actuator 37 is energized, and its output end extends or retracts, driving the pressure regulating plate 38 fixedly connected to it to move. Since the auxiliary support plate 33 is fixedly connected to the end of the filter plate 32 near the electric actuator 37 and is rotatably connected to the pressure regulating plate 38 along the same axis, the movement of the pressure regulating plate 38 will drive the auxiliary support plate 33 to move, and then drive the filter plate 32 to move, thereby achieving the alignment and misalignment of the filter holes on the filter screen 31 and the filter holes on the filter plate 32.

[0053] To prevent filter 31 from deforming, the following features are also specifically designed:

[0054] Two buffer shafts 34 are arranged at equal angles along the circumferential direction at the end of the main frame 13 away from the ball mill cylinder 1 (e.g., Figure 4 As shown, one end of the buffer shaft 34 is fixedly connected to the main frame 13, and the other end is slidably connected to the auxiliary support plate 33. A tension spring 35 is coaxially mounted on the outside of the buffer shaft 34. One end of the tension spring 35 is fixedly connected to the main frame 13, and the other end is fixedly connected to the auxiliary support plate 33. When the pressure regulating plate 38 moves the filter plate 32, the tension spring 35 can buffer the filter plate 32 through its own elastic deformation, preventing the relative displacement between the filter plate 32 and the filter screen 31 from being affected by deformation, thus ensuring the normal operation of the device.

[0055] A production process for recycling ultrafine tungsten oxide waste also includes the following steps:

[0056] S1: The operator opens the feed port of the ball mill cylinder 1 corresponding to the grinding chamber 3 and slowly and evenly pours the waste material containing ultrafine tungsten oxide to be recycled into the grinding chamber 3;

[0057] S2: Start the device. The ball mill cylinder 1 rotates along the circumference of the main seat 11. During this process, the material in the grinding chamber 3 will pass through the filter screen 31 and move into the receiving chamber 4.

[0058] S3: When the amount of material recovered in the containment chamber 4 reaches the expected amount or the predetermined production task is completed, the operator shuts down the equipment and then discharges and collects the recovered ultrafine tungsten oxide material in the containment chamber 4.

[0059] S4: The operator cleans the inside of the ball mill cylinder 1, the grinding media 41, the filter screen 31, the filter plate 32 and other components to remove residual materials and prepare for the next production.

[0060] The working principle of this device is as follows: The operator first places the waste material containing ultrafine tungsten oxide into the grinding chamber 3 of the ball mill cylinder 1. Several grinding media 41 are pre-placed in the grinding chamber 3. After the equipment is started, the main motor 7 operates, driving the rotating shaft 10 to rotate via the main pulley 8, belt, and auxiliary pulley 9. This causes the rocker arm 24 to rotate around the center of the main seat 11, and the rocker arm 24 drives the ball mill cylinder 1 to move circumferentially along the main seat 11. When the main gear ring 2 meshes with the main arc tooth 12, the main gear ring 2 drives the ball mill cylinder 1 to rotate. At this time, the filter screen 31 remains horizontal under the action of the horizontal holding mechanism 15, and the grinding media 41 grinds the material. During this process, the edge of the filter screen 31 can comb through the material adhering to the grinding chamber 1, improving the degree of material breakage by the grinding media 41. Simultaneously, the filter screen 31 does not come into contact with the grinding media 41 during this process, reducing the contact frequency between the grinding media 41 and the filter screen 31 and extending the service life of the filter screen 31.

[0061] In the horizontal holding mechanism 15, the balancing motor 20 drives the stabilizing gear 17 through the electromagnetic clutch 19, which interacts with the balancing gear ring 16 coaxially fixed on the main frame 13 to ensure that the filter screen 31 is horizontal. As the ball mill cylinder 1 moves, when the auxiliary gear ring 6 meshes with the auxiliary arc tooth 22, the ball mill cylinder 1 and the filter screen 31 rotate synchronously along the center direction of the ball mill cylinder 1 under the action of the one-way bearing 5.

[0062] During this process, the electric actuator 37 drives the pressure regulating plate 38 to move, and the pressure regulating plate 38 drives the auxiliary support plate 33 and the filter plate 32 to move, so that the filter screen 31 and the filter holes of the filter plate 32 are repeatedly aligned and staggered, allowing the material crushed to the appropriate particle size in the grinding chamber 3 to pass through the filter screen 31 and enter the receiving chamber 4, thereby realizing the recycling of ultrafine tungsten oxide waste.

[0063] During the above process, the limiting shaft 27 slides in the limiting groove 23 to ensure the stable movement of the rocker arm 24, while the buffer shaft 34 and the tension spring 35 prevent the filter screen 31 from deforming, ensuring the stable and efficient operation of the entire device.

[0064] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
