Description

Technical Field

[0001] This utility model relates to the field of powder conveying technology, and in particular to a powder silo discharge anti-blocking device. Background Technology

[0002] A powder silo is a container used to store and manage powdered materials. It is widely used in industries such as industrial production, construction, chemical industry, food processing, and pharmaceuticals. Its main function is to store and distribute various powdered materials and ensure that the materials can be smoothly transported to the next process or equipment.

[0003] Currently, there are various types of powder silos on the market. However, due to the nature of the materials, powder is prone to clogging inside these silos, especially in environments where the silos remain stationary for extended periods or where temperature and humidity fluctuate significantly. In such cases, the powder can adhere to the silo walls, causing blockages at the discharge port and preventing the material from flowing out smoothly. This results in production stagnation and disruption of normal operations, impacting production efficiency. Summary of the Invention

[0004] This invention addresses the problem that some devices on the market, due to the nature of the materials, are prone to clogging in the silo with powder, especially in environments with long periods of inactivity or large temperature and humidity changes. In such cases, the powder adheres to the silo wall, causing blockage at the discharge port and preventing the material from flowing out smoothly. This results in production stagnation and inability to work normally, thus affecting production efficiency. Therefore, this invention provides a powder silo discharge anti-clogging device.

[0005] This utility model is achieved using the following technical solution: a powder silo discharge anti-blocking device, comprising a striking mechanism, an auxiliary mechanism, and a protective mechanism. The striking mechanism is located inside the protective mechanism, and the auxiliary mechanism is located in the middle of the protective mechanism. The striking mechanism includes a drive motor, the output end of which is fixedly connected to a connecting shaft. The rear end of the connecting shaft is fixedly connected to a drive toothed pulley. A synchronous toothed belt meshes with the surface of the drive toothed pulley. A driven toothed pulley is driven through the inner wall of the synchronous toothed belt. A connecting shaft is fixedly connected to the front end of the driven toothed pulley. Fixed posts are fixedly connected to the surfaces of both the connecting shaft and the connecting shaft. Limiting posts are slidably connected to the inner walls of the fixed posts. Springs are fixedly connected to the inner sides of the limiting posts. Limiting shells are fixedly connected to the outer sides of the limiting posts. Rollers are rotatably connected to the inner walls of the limiting shells. The drive toothed pulley is located above the driven toothed pulley.

[0006] Through the above technical solution, the diameter of the active toothed belt pulley is larger than that of the driven toothed belt pulley, resulting in different rotation speeds between the two. During the rotation process, the roller will contact and collide with the inner wall of the housing. The squeezing action of the inner wall of the housing on the roller generates a vibration force, thereby generating periodic vibration in the hopper, ensuring that the powder can flow smoothly to the discharge port.

[0007] As a further improvement to the above solution, the auxiliary mechanism includes a second drive motor, the output end of which is fixedly connected to a cylinder, and a rotating plate is fixedly connected to the surface of the cylinder. The number of rotating plates is set to two, and the two rotating plates are symmetrically distributed with the cylinder as the center.

[0008] Through the above technical solution, after the second drive motor starts, it drives the cylinder to rotate, thereby allowing the rotating plate to stir the powder inside the shell, further helping to improve the flowability of the material in the silo.

[0009] As a further improvement to the above solution, the protective mechanism includes a housing, an inlet pipe fixedly connected to the upper end of the housing, an outlet pipe fixedly connected to the bottom of the housing, the front end of the connecting shaft II rotatably connected to the inner wall of the housing, the roller located inside the housing, and the rotating plate located inside the housing.

[0010] Using the above technical solution, the operator conveys the powder from the feed pipe into the interior of the shell, and when it needs to be removed, the powder is transported out from the discharge pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention features a striking mechanism. When the drive motor starts, it rotates the first connecting shaft. The first connecting shaft, via a synchronous toothed belt, drives the driven toothed pulley to rotate, causing the second connecting shaft to rotate as well. The rotation of the first and second connecting shafts together drives the fixed post and the limiting post. When the roller collides with the inner wall of the housing, the limiting post is pushed inward, and the spring is compressed, effectively mitigating the mechanical impact of the collision and reducing wear and energy loss during operation. The diameter of the driving toothed pulley is larger than that of the driven toothed pulley, resulting in a faster rotation frequency of the roller mounted on the driven toothed pulley, ensuring that the powder flows smoothly from the outlet.

[0013] This utility model, by setting up an auxiliary mechanism, drives the cylinder to rotate after the second drive motor starts, which in turn drives the rotating plate to rotate. The rotating plate stirs the powder inside the shell, thereby improving the flowability of the powder in the hopper. This process helps to ensure that the powder can flow smoothly out of the discharge pipe after being affected by vibration, thereby further improving the actual effect. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example:

[0023] Please combine Figure 1-5 This embodiment of a powder silo discharge anti-clogging device includes a striking mechanism 1, an auxiliary mechanism 2, and a protective mechanism 3. The striking mechanism 1 is located inside the protective mechanism 3, and the auxiliary mechanism 2 is located in the middle of the protective mechanism 3. The striking mechanism 1 includes a drive motor 11, the output end of which is fixedly connected to a connecting shaft 12. The rear end of the connecting shaft 12 is fixedly connected to a drive toothed pulley 13. A synchronous toothed belt 14 meshes with the surface of the drive toothed pulley 13. A driven toothed pulley 15 drives the inner wall of the synchronous toothed belt 14. A connecting shaft 2 16 is fixedly connected to the front end of the driven toothed pulley 15. Fixed posts 1 are fixedly connected to the surfaces of both the connecting shaft 12 and the connecting shaft 2 16. 7. Limiting posts 18 are slidably connected to the inner walls of the fixed posts 17. Springs 19 are fixedly connected to the inner sides of the limiting posts 18. Limiting shells 191 are fixedly connected to the outer sides of the limiting posts 18. Rollers 192 are rotatably connected to the inner walls of the limiting shells 191. The driving toothed pulley 13 is located at the upper end of the driven toothed pulley 15. The diameter of the driving toothed pulley 13 is larger than that of the driven toothed pulley 15, resulting in different rotation speeds. During rotation, the rollers 192 will contact and collide with the inner walls of the housing 31. The squeezing action of the inner walls of the housing 31 on the rollers 192 generates a vibration force, thereby generating periodic vibrations in the hopper, ensuring that the powder can flow smoothly to the discharge port.

[0024] The auxiliary mechanism 2 includes a second drive motor 21. A cylinder 22 is fixedly connected to the output end of the second drive motor 21. A rotating plate 23 is fixedly connected to the surface of the cylinder 22. The number of rotating plates 23 is set to two. The two rotating plates 23 are symmetrically distributed around the cylinder 22. After the second drive motor 21 is started, it drives the cylinder 22 to rotate, thereby allowing the rotating plates 23 to stir the powder inside the shell 31, further helping to improve the flowability of the material in the silo.

[0025] The protective mechanism 3 includes a housing 31, with a feed pipe 32 fixedly connected to the upper end of the housing 31 and a discharge pipe 33 fixedly connected to the bottom of the housing 31. The front end of the connecting shaft 16 is rotatably connected to the inner wall of the housing 31. The roller 192 is located inside the housing 31, and the rotating plate 23 is located inside the housing 31. The operator conveys the powder from the feed pipe 32 to the inside of the housing 31. When it needs to be removed, the powder is transported out from the discharge pipe 33.

[0026] The implementation principle of the powder silo discharge anti-blocking device in this embodiment is as follows: The operator connects an external power source to start the motor 11. The motor 11 drives the connecting shaft 12 to rotate, which in turn drives the drive gear pulley 13 to rotate. The rotating drive gear pulley 13 then drives the driven gear pulley 15 to rotate via the synchronous gear belt 14, causing the connecting shaft 16 to rotate as well. At this time, the fixed posts 17 on both the connecting shaft 12 and the connecting shaft 16 are also driven to rotate together. The rotating fixed posts 17... The limiting post 18 drives the limiting shell 191 to rotate together, thereby causing the roller 192 to rotate as well. When the roller 192 rotates to a certain position, it will contact and collide with the inner wall of the shell 31. During the collision, the inner wall of the shell 31 will squeeze the roller 192. At this time, the limiting post 18 will be driven to move inward together, and the spring 19 will be compressed by the squeezing force of the limiting post 18. The roller 192 can then roll on the inner wall of the shell 31, thereby further reducing the loss generated during the collision, because the diameter of the driving toothed pulley 13 is larger. Because the driven toothed pulley 15 has a smaller diameter than the driving toothed pulley 13, the rollers 192 on the driven toothed pulley 15 rotate at different speeds, resulting in different frequencies at which the rollers 192 strike the inner wall of the housing 31. The driven toothed pulley 15 is closer to the discharge pipe 33. Since the diameter of the driven toothed pulley 15 is smaller than that of the driving toothed pulley 13, the rollers 192 on the driven toothed pulley 15 strike the inner wall of the housing 31 at a faster frequency, causing vibration in the hopper. This vibration helps to address issues such as material blockage and agglomeration, ensuring smooth material flow through the discharge port. Meanwhile, the rollers 192 on the driving toothed pulley 13 only need to ensure the overall flowability of the material. By connecting an external power source to start the drive motor 21, the drive motor 21 can drive the cylinder 22 to rotate. The rotating cylinder 22 can drive the rotating plate 23 to rotate, thereby causing the rotating plate 23 to stir the material inside the shell 31, thereby further promoting the flowability of the material inside the shell 31, thus ensuring that the material can be smoothly discharged from the discharge pipe 33. The operator continuously feeds the material into the shell 31 through the feed pipe 32. The entire device can ensure the flowability of the material inside the shell 31, and the vibration allows it to be smoothly discharged from the discharge pipe 33.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
