Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a grinding device for batch feeding in activated carbon processing and production. Background Technology

[0002] Activated carbon grinding equipment, a key piece of equipment for processing activated carbon powder, is widely used in chemical, environmental protection, and food processing fields. It is mainly used for crushing, fine grinding, and grading materials to meet the particle size requirements of activated carbon in different industries. Publication number CN219785082U discloses an activated carbon grinding device, relating to the technical field of grinding equipment. The device includes a main body, with a connecting rod fixedly connected to the upper end of one side and a support rod fixedly connected to the lower end of the same side. A feeding device is connected to the connecting rod and the support rod. The feeding device includes a feeding cylinder, inside which a conveying auger is rotatably arranged. A discharge nozzle is fixedly connected to the upper end of the feeding cylinder, and a feed hopper is fixedly connected to the lower end of the feeding cylinder. This novel activated carbon grinding device features a placement box. By incorporating a feeding device and a vibration assembly, the material can be fed without manual lifting and pouring. The conveying auger ensures more even material distribution, preventing blockages at the top of the device. The vibration assembly within the placement box further prevents blockages when pouring the material into the feed hopper. While the auger and vibration assembly provide uniform material distribution and prevent blockages at the top, this device is not suitable for processing difficult activated carbon materials, such as those with complex pore structures or hard textures. Multiple grinding processes may not achieve the desired fineness, necessitating efficient sieving of the ground activated carbon. Further improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a grinding device for batch feeding in activated carbon processing and production, including a screening box, a foot bracket and a discharge port fixedly installed on the lower surface of the screening box, a grinding box fixedly installed on the upper surface of the screening box, a grinding wall and a motor frame fixedly installed inside the grinding box, a grinding motor fixedly installed on the surface of the motor frame, a grinding cylinder fixedly installed at the output end of the grinding motor, a grinding rod fixedly installed on the surface of the grinding cylinder, a vibration motor fixedly installed on the surface of the screening box, a support frame fixedly installed on the inner side of the screening box, a cam fixedly installed at the output end of the vibration motor, a rotating shaft fixedly installed on the surface of the cam, a driven rod rotatably connected to the surface of the rotating shaft, a connecting block rotatably connected to the other end of the driven rod, a screening plate fixedly installed on the surface of the connecting block, a uniform plate fixedly installed on the upper surface of the screening plate, a support block fixedly installed on the lower surface of the screening plate, a support rod fixedly installed on the surface of the support frame, and a rotating hole opened on the surface of the support rod.

[0005] Preferably, the grinding rod has serrations evenly distributed circumferentially on its surface, and the surface of the grinding rod is in close contact with the inner side of the grinding wall. This allows for a tighter and more comprehensive contact between the grinding rod and the grinding wall, resulting in more thorough compression and grinding of the material during the grinding process. This reduces the chance of material being missed or incompletely ground. The evenly distributed grinding rod ensures a more balanced force on the material during the rotation of the grinding cylinder, preventing over- or under-grinding due to uneven force in certain areas. This improves the overall grinding effect, resulting in a more consistent degree of grinding. The serrations on the surface enhance the friction between the grinding rod and the material, further strengthening the grinding action and allowing the material to reach the required fineness more quickly after grinding. This improves the efficiency of the grinding process and provides a more suitable material basis for subsequent screening.

[0006] Preferably, there are two cams symmetrically distributed on both sides of the screening plate, and two material leveling plates symmetrically and alternately distributed on the surface of the screening plate. Here, the two symmetrically distributed cams can simultaneously apply force from both sides of the screening plate, making the force on the screening plate more balanced during vibration. This avoids tilting or unstable vibration of the screening plate due to unilateral force, ensuring uniform overall vibration amplitude and improving the stability of the screening process. The material leveling plates can divert and guide the material when it falls onto the screening plate, preventing local accumulation and allowing for more even distribution of material on the screening plate surface. This fully utilizes the effective screening area of ​​the screening plate, improves screening efficiency, ensures that material at different locations is fully screened, and reduces incomplete screening caused by material accumulation.

[0007] Preferably, there are two support rods symmetrically distributed on both sides of the screening plate, and the surface of the rotating hole and the surface of the support block are rotatably connected. This provides a reliable mounting base for the vibration of the screening plate, preventing swaying or displacement during high-frequency vibration and ensuring the overall stability of the screening plate structure. The rotatable connection between the rotating hole and the support block allows the screening plate to swing flexibly around the support rod as a fulcrum. Combined with the transmission action of the cam and driven rod, this makes the vibration of the screening plate smoother, reducing jamming or resistance during movement, ensuring stable vibration screening performance, and improving the screening efficiency and accuracy of materials.

[0008] Preferably, a conveyor motor and a feeding pipe are fixedly installed on the surface of the screening box. A stirring blade is fixedly installed at the output end of the conveyor motor. A feeding port is fixedly installed on the upper surface of the grinding box. A storage hopper is fixedly installed on the surface of the feeding port. A material control motor is fixedly installed on the surface of the feeding port, and a material control plate is fixedly installed at the output end of the material control motor. Here, the conveyor motor drives the stirring blade to rotate, which can push materials that do not meet the standards after screening and send them out through the feeding pipe. These materials can then be re-input into the grinding stage, achieving material recycling. The storage hopper can temporarily store the materials to be ground. The material control motor drives the material control plate to flexibly adjust the opening and closing degree of the feeding port, thereby controlling the speed and amount of material fed into the grinding box. This prevents material accumulation in the grinding box due to excessive feeding, which would affect the grinding effect, and also avoids equipment idling due to insufficient feeding, improving the stability of equipment operation and the continuity of material processing.

[0009] Preferably, the stirring blade extends through the screening box to the inside of the conveying pipe. The surface length of the control plate is the same as the inner length of the feeding port. The surface of the control plate can be brought into contact with the inner side of the feeding port by the rotation of the control motor. Here, the stirring blade extending into the inside of the conveying pipe ensures a continuous pushing force for substandard materials, preventing material from stagnating or clogging at the junction of the screening box and the conveying pipe, ensuring smooth and efficient circulation. The control plate's consistent length with the inner side of the feeding port and its contact via the rotation of the control motor allow for precise control of the feeding port's closure. When feeding needs to be stopped, the material's fall can be completely blocked. When adjusting the feeding amount, the opening size can be stably controlled by the rotation angle of the control plate, making the material input more precise. This further ensures the feeding stability of the grinding process and improves the overall controllability of the processing.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by setting up a grinding cylinder, grinding rods, a vibrating motor, a sieve plate, a cam, and a uniform material plate, the synergistic effect of these structures is utilized. The grinding cylinder rotates, causing the grinding rods to cooperate with the grinding wall to grind the input activated carbon material. The vibrating motor drives the cam to rotate, which in turn drives the sieve plate to vibrate around the support rod as a fulcrum via the driven rod. The symmetrically distributed cams ensure that the sieve plate is subjected to balanced force and stable vibration. The uniform material plate diverts and guides the material falling onto the sieve plate to avoid accumulation, allowing the material to be evenly distributed on the surface of the sieve plate, thereby improving sieving efficiency. This realizes a continuous process from grinding to sieving of activated carbon, which not only ensures the sufficiency of grinding and the accuracy of sieving, but also improves the overall processing efficiency and material utilization rate.

[0012] 2. In this utility model, by setting up a conveyor motor, stirring blades, feeding port, material control motor, and material control plate, the material control motor drives the material control plate to move, which can flexibly adjust the opening and closing degree of the feeding port according to the grinding rhythm, accurately control the amount of material input, avoid excessive accumulation of material in the grinding box or insufficient idling, and ensure stable operation of the grinding process. When substandard material appears after screening, the conveyor motor drives the stirring blades to rotate. The stirring blades penetrate through the screening box to the inside of the conveying pipe, which can continuously and stably push these materials out of the screening box for re-grinding, forming a cycle of grinding. The material control structure ensures the controllability of the feeding, and the conveying structure realizes the efficient delivery of materials, reducing resource waste and improving the continuity of activated carbon processing and the stability of finished product quality.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1

[0023] Please see Figure 1-4This utility model provides a technical solution: a batch feeding grinding device for activated carbon processing, including a screening box 1, which serves as one of the basic structures of the device, providing installation space and support for the internal screening mechanism, conveying mechanism, etc., while forming a relatively closed screening environment to prevent material from scattering during screening. A support frame 2 and a discharge port 3 are fixedly installed on the lower surface of the screening box 1, and a grinding box 4 is fixedly installed on the upper surface of the screening box 1, providing a closed space for the grinding process to prevent material splashing during grinding, while also supporting grinding-related components such as the grinding wall 5 and motor frame 6. The grinding wall 5 and motor frame 6 are fixedly installed inside the grinding box 4, and a grinding motor 7 is fixedly installed on the surface of the motor frame 6. A grinding wheel is fixedly installed at the output end of the grinding motor 7. Grinding cylinder 8 has grinding rods 9 fixedly mounted on its surface. The grinding rods 9 have serrations evenly distributed circumferentially on their surface. The surfaces of the grinding rods 9 and the inner side of the grinding wall 5 are in close contact, ensuring a tighter and more comprehensive contact between them. This allows for more thorough compression and grinding of the material during the grinding process, reducing the chance of material being missed or incompletely ground. The evenly distributed grinding rods 9 also ensure a more balanced force on the material during the rotation of the grinding cylinder 8, preventing over- or under-grinding due to uneven force in certain areas. This contributes to improving the overall grinding effect and ensuring a more consistent degree of grinding. The serrations on the surface further enhance the contact between the grinding rods 9 and the material. The friction force further enhances the grinding effect on the material, enabling the material to reach the required fineness more quickly after grinding, improving the efficiency of the grinding process, and providing a more suitable material basis for subsequent screening. A vibrating motor 10 is fixedly installed on the surface of the screening box 1, and a support frame 11 is fixedly installed on the inner side of the screening box 1. A cam 12 is fixedly installed at the output end of the vibrating motor 10, and a rotating shaft 13 is fixedly installed on the surface of the cam 12. A driven rod 14 is rotatably connected to the surface of the rotating shaft 13, and a connecting block 15 is rotatably connected to the other end of the driven rod 14. A screening plate 16 is fixedly installed on the surface of the connecting block 15, and a material leveling plate 17 is fixedly installed on the upper surface of the screening plate 16. There are two cams 12, symmetrically distributed on both sides of the screening plate 16, for material leveling. Two plates 17 are symmetrically and alternately distributed on the surface of the screening plate 16. Here, the two symmetrically distributed cams 12 can apply forces simultaneously from both sides of the screening plate 16, making the force on the screening plate 16 more balanced during vibration. This avoids the situation where the screening plate 16 tilts or vibrates unstably due to force on one side, ensuring that the overall vibration amplitude of the screening plate 16 is uniform and improving the stability of the screening process. The material distribution plate 17 can divert and guide the material when it falls onto the screening plate 16, preventing the material from accumulating locally on the screening plate 16, and allowing the material to be more evenly distributed on the surface of the screening plate 16. This fully utilizes the effective screening area of ​​the screening plate 16, improves screening efficiency, ensures that the material at different positions is fully screened, and reduces the problem of incomplete screening caused by material accumulation.A support block 18 is fixedly installed on the lower surface of the screening plate 16, and a support rod 19 is fixedly installed on the surface of the support frame 11. Rotating holes 20 are formed on the surface of the support rod 19. There are two support rods 19, symmetrically distributed on both sides of the screening plate 16. The surface of the rotating hole 20 and the surface of the support block 18 are rotatably connected. This provides a reliable mounting foundation for the vibration of the screening plate 16, preventing the screening plate 16 from shaking or shifting during high-frequency vibration, ensuring the overall stability of the screening plate 16. The rotatable connection between the rotating hole 20 and the support block 18 allows the screening plate 16 to swing flexibly around the support rod 19 as a fulcrum. Combined with the transmission action of the cam 12 and the driven rod 14, this makes the vibration of the screening plate 16 smoother, reducing jamming or resistance during movement, ensuring stable vibration screening performance, and improving the screening efficiency and accuracy of materials.

[0024] Example 2

[0025] Please see Figure 5A conveyor motor 21 and a conveying pipe 23 are fixedly installed on the surface of the screening box 1. An agitator 22 is fixedly installed at the output end of the conveyor motor 21, rotating under the drive of the motor to push materials that do not meet the screening standards, ensuring that the materials can be smoothly conveyed through the conveying pipe 23 and avoiding material stagnation and blockage. A feeding port 24 is fixedly installed on the upper surface of the grinding box 4, serving as the channel for materials to enter the grinding box 4. It connects the storage hopper 25 and the grinding box 4, controlling the material input path. A storage hopper 25 is fixedly installed on the surface of the feeding port 24. A material control motor 26 is fixedly installed on the surface of the feed inlet 24. A material control plate 27 is fixedly installed on the output end of the material control motor 26. Here, the conveying motor 21 drives the stirring blade 22 to rotate, which can push the material that does not meet the standard after screening and send it out through the conveying pipe 23. It can be put back into the grinding stage to realize the recycling of materials. The storage hopper 25 can temporarily store the material to be ground. The material control motor 26 drives the material control plate 27 to move, which can flexibly adjust the opening and closing degree of the feed inlet 24, thereby controlling the speed and amount of material put into the grinding box 4 and preventing the material from being put into the grinding box 4 due to improper feeding. Excessive material feeding leads to material accumulation in the grinding chamber 4, affecting the grinding effect. Insufficient feeding also prevents the equipment from idling, improving the stability of equipment operation and the continuity of material processing. The stirring blade 22 penetrates the interior of the screening box 1 to the conveying pipe 23. The surface length of the control plate 27 is the same as the inner length of the feeding port 24. The surface of the control plate 27 can be brought into contact with the inner side of the feeding port 24 by the rotation of the control motor 26. Here, the stirring blade 22 penetrates into the interior of the conveying pipe 23, ensuring a continuous pushing force for substandard materials throughout the process, avoiding… To prevent material from stagnating or clogging at the connection between the screening box 1 and the conveying pipe 23, ensuring smooth and efficient circulation, the control plate 27 and the inner side of the feeding port 24 are of the same length and can be fitted together by rotating the control motor 26. This allows for precise control of the closing state of the feeding port 24, completely blocking the material from falling when feeding needs to be stopped. When adjusting the feeding amount, the opening size can be stably controlled by rotating the control plate 27, making the control of the material input amount more precise, further ensuring the feeding stability of the grinding process and improving the overall controllability of the processing.

[0026] Working Principle: When dealing with some difficult-to-process activated carbon raw materials, such as those with complex pore structures or hard textures, a single grinding process may not achieve the desired fineness, requiring multiple grinding operations. For efficient screening of the ground activated carbon raw materials, the raw materials are placed in the storage hopper 25. The material control motor 26 drives the material control plate 27 to adjust the feeding port 24, allowing an appropriate amount of raw material to be fed into the grinding chamber 4. The grinding motor 7 drives the grinding cylinder 8 to rotate, and the grinding rods 9 cooperate with the grinding wall 5 to grind the input raw material. The refined material falls onto the screening plate. On 16, the vibrating motor 10 drives the cam 12 to rotate, which in turn drives the driven rod 14 to move through the rotating shaft 13. This causes the connecting block 15 to drive the screening plate 16 to vibrate with the support rod 19 as the fulcrum. The uniform plate 17 diverts and guides the material to avoid accumulation. The qualified material is discharged from the discharge port 3 through the screening plate 16. The conveying motor 21 drives the stirring blade 22 to rotate, pushing the unqualified material to the conveying pipe 23. The material is then sent out of the screening box 1 through the conveying pipe 23 and ground again as needed. This cycle is repeated to ensure that the raw materials are fully ground and screened to meet the processing requirements.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
