Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for material conveying, and in particular to an anti-blocking vibration device for concentrate hoppers. Background Technology

[0002] As an important raw material in the metallurgical industry, concentrate powder typically has physical characteristics such as fine particle size, high moisture content, and high viscosity. In industrial production, hoppers are usually used for temporary storage and transfer of concentrate powder to facilitate continuous processing in subsequent processes. However, due to the large internal friction and adhesion between concentrate powder materials, as the material is discharged from the hopper outlet by gravity, a stable arched consolidation structure or rat hole effect is easily formed inside the hopper, causing the material to fall smoothly and resulting in serious blockage, which affects the normal operation of the production line.

[0003] To address this issue, existing technologies often employ the method of installing a vibrating motor on the outer wall of the hopper, attempting to disrupt the material's solidified structure through high-frequency vibration. However, for highly viscous concentrates that easily adhere to the bottom of the hopper's inner wall, simple external vibration is often insufficient to completely dislodge the stubborn material layer adhering to the inner wall. Sometimes, continuous vibration can even lead to further compaction of the material, making it impossible to actively clean the easily adhering areas inside, resulting in poor anti-clogging performance.

[0004] Therefore, this utility model proposes an anti-blocking vibration device for concentrate hoppers to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems in the existing technology, such as the inability to completely destroy the stubborn solidified structure by simply relying on external vibration, the inability to effectively clean the material adhering to the bottom of the hopper, resulting in poor anti-clogging effect and low reliability, this utility model aims to provide an anti-clogging vibration device for concentrate hoppers with an improved structure that can effectively solve the above problems.

[0006] This utility model provides an anti-blocking vibration device for a concentrate hopper, including a hopper body, a discharge port fixedly connected to the bottom of the hopper body, an installation plate fixedly connected to the front side of the hopper body, a vibration motor fixedly connected to one side of the installation plate, and cylinders fixedly connected to the top of both the left and right sides of the hopper body. Limiting posts are fixedly connected to the four corners of the top of the hopper body, and connecting frames are slidably connected to the outer surface of the limiting posts. The bottom of the left and right sides of the connecting frames are fixedly connected to the output end of the cylinders.

[0007] The connecting frame has a connecting plate fixedly connected to each of its four bottom sides. A push plate is fixedly connected to the bottom of the connecting plate. A fixing groove is opened at the bottom of the push plate. One end of a spring is fixedly connected inside the fixing groove, and a scraper is fixedly connected to the other end of the spring.

[0008] Furthermore, the cylinder, the connecting frame, the connecting plate, the pushing plate, and the scraper are combined in a linkage manner. The cylinder drives the connecting frame to slide along the guide post, thereby driving the scraper at the bottom to scrape and clean the inside of the hopper. With the elastic buffering effect of the spring, flexible anti-clogging treatment is achieved on the inner wall and bottom of the hopper.

[0009] Preferably, the connecting frame has positioning holes at all four corners, and the connecting frame is slidably connected to the outer surface of the limiting post through the positioning holes. This fit ensures the verticality and stability of the connecting frame during movement and prevents deflection. A limiting block is fixedly connected to the top of the limiting post, with the bottom surface of the limiting block contacting the top surface of the limiting post. The limiting block limits the sliding stroke of the connecting frame on the limiting post and prevents the connecting frame from falling off the limiting post. Fixing plates are provided on the left and right outer walls of the hopper body. The fixing plates are used to assist in fixing the hopper body, and threaded holes are provided on the inner side of the fixing plates. Bolts are threaded into the threaded holes, and the device is stably installed through the cooperation of the bolts and the fixing plates.

[0010] Preferably, a control panel is fixedly connected to the front side of the discharge port. The control panel is electrically connected to the vibrating motor and the cylinder. Furthermore, control buttons are provided at the bottom of the control panel to facilitate real-time control of the equipment's operating status by the operator. A feed inlet is located at the center of the top of the hopper body, penetrating the top wall of the hopper body for convenient material feeding.

[0011] This utility model has the following beneficial effects: 1. This utility model solves the problem that existing concentrate hoppers cannot completely remove stubborn adhesives and solidified structures by using a single vibration method, which is achieved by setting a vibration motor on the outside of the hopper body to generate high-frequency vibration waves and cooperating with the internal scraper assembly driven by a cylinder for mechanical scraping. It achieves a dual anti-blocking effect of destroying the solidified state of the material and forcibly cleaning the bottom of the inner wall, which significantly improves the smoothness of material discharge and the operating efficiency of the equipment.

[0012] 2. This utility model solves the problem that traditional rigid scrapers are prone to damage due to hard impacts or cannot adapt to the slight deformation of the inner wall of the hopper during operation by setting a spring-connected scraper in the fixing groove at the bottom of the push plate. It achieves the effect of providing effective buffer protection when the scraper is subjected to resistance, and automatically resetting with elasticity after the resistance disappears to closely fit the inner wall of the hopper for thorough cleaning, thus extending the service life of the device.

[0013] 3. This utility model solves the problem of tilting, shaking or mechanical jamming that easily occurs when the internal cleaning component performs long-stroke reciprocating motion under the drive of the cylinder by setting limiting posts at the four corners of the top of the hopper body and using the positioning holes at the four corners of the connecting frame to form a four-point positioning sliding fit with the limiting posts. This achieves the technical effect of ensuring that the scraper assembly always runs vertically and stably along the predetermined trajectory, greatly enhancing the stability and reliability of the device operation.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] Example: Please refer to Figures 1 to 4 This utility model provides an anti-clogging vibration device for concentrate hoppers, which aims to solve the problem that existing concentrate materials are prone to solidification inside the hopper, causing discharge blockage and that simple vibration is not enough to completely remove stubborn adhesives.

[0018] like Figure 1 and Figure 2As shown, the anti-clogging vibration device for a concentrate hopper includes a hopper body 6 and a discharge port 1 fixedly connected to the bottom of the hopper body 6. The hopper body 6 serves as the core carrier for material storage and flow. The discharge port 1 is used to discharge the internal material. An installation plate 4 is fixedly connected to the front side of the hopper body 6. A vibration motor 5 is fixedly connected to one side of the installation plate 4. The vibration motor 5 serves as a power source to generate high-frequency vibration waves and transmit them to the hopper body 6 to break the material's solidified structure. A feed inlet 9 is opened at the top center of the hopper body 6. The feed inlet 9 penetrates the top wall of the hopper body 6 for feeding materials.

[0019] Fixing plates 7 are provided on the outer walls of both sides of the hopper body 6. The fixing plates 7 are used to assist in fixing the hopper body 6. Threaded holes are opened on the inner side of the fixing plates 7, and bolts 8 are threaded inside the threaded holes. The device is fixed in the working position by the cooperation of the fixing plates 7 and the bolts 8. A control panel 2 is fixedly connected to the front side of the discharge port 1. A control button 3 is provided at the bottom of the control panel 2. The control panel 2 is electrically connected to the vibration motor 5 and the cylinder 10 respectively. The operation of the components is controlled by the control button 3. Cylinders 10 are fixedly connected to the top of both sides of the hopper body 6. Limiting posts 11 are fixedly connected to the four corners of the top of the hopper body 6. The cylinders 10 are used as the driving source to provide linear power, and the limiting posts 11 are used to provide guide support for the moving parts.

[0020] To solve the aforementioned technical problems, the core of the technical solution in this embodiment lies in the fact that the anti-blocking vibration device for the concentrate hopper also includes a scraper 18 and a cooperating drive and guide structure. Furthermore, the scraper 18 forms a specific structural fit and connection relationship with the aforementioned hopper body 6 and cylinder 10. Please refer to [the relevant documentation / reference]. Figure 3 and Figure 4 The core structure will now be explained in detail.

[0021] A connecting frame 13 is slidably connected to the outer surface of the limiting post 11. The connecting frame 13 has a rectangular frame structure and is sleeved on the outside of the four limiting posts 11. The bottom ends of the left and right sides of the connecting frame 13 are fixedly connected to the output end of the cylinder 10. The connecting frame 13 is driven to slide up and down along the limiting post 11 by the extension and retraction movement of the cylinder 10. Positioning holes 14 are provided at the four corners of the connecting frame 13. The connecting frame 13 is slidably connected to the outer surface of the limiting post 11 through the positioning holes 14. The cooperation between the positioning holes 14 and the limiting post 11 can limit the horizontal displacement of the connecting frame 13 and ensure the stability of its vertical movement. A limiting block 12 is fixedly connected to the top of the limiting post 11. The bottom end face of the limiting block 12 contacts the top end face of the limiting post 11. The limiting block 12 is used to limit the sliding stroke of the connecting frame 13 on the limiting post 11 and prevent the connecting frame 13 from falling off.

[0022] Connecting plates 15 are fixedly connected to the four sides of the bottom of the connecting frame 13. The connecting plates 15 extend downward and are used to transmit driving force. A push plate 16 is fixedly connected to the bottom of the connecting plate 15. The push plate 16 moves up and down synchronously with the connecting frame 13. A fixing groove 19 is opened at the bottom of the push plate 16. The fixing groove 19 is a long strip-shaped groove structure that extends along the length of the push plate 16. One end of a spring 17 is fixedly connected inside the fixing groove 19. The spring 17 extends vertically downward. A scraper 18 is fixedly connected to the other end of the spring 17. The scraper 18 is located at the bottom of the inside of the hopper body 6 and is used to scrape off the sticky material. The spring 17 can provide buffering and reset function after the scraper 18 is resisted.

[0023] Based on the above embodiments, in order to provide a stable scraping and buffering effect, a fixing groove 19 is provided at the bottom of the push plate 16. The fixing groove 19 contains a plurality of springs 17 arranged at intervals. By setting a plurality of springs 17, the scraper 18 can be subjected to more uniform force. When the scraper 18 encounters a hard block or an irregular protrusion on the inner wall of the hopper during the downward scraping process, the spring 17 is compressed and deformed to buffer the rigid impact. After the resistance disappears, the spring force drives the scraper 18 to reset so as to maintain the fit with the cleaning surface.

[0024] To ensure the smoothness and accuracy of the movement of the connecting frame 13, positioning holes 14 are provided at each of the four corners of the connecting frame 13. The four positioning holes 14 are respectively slidably engaged with the four limiting posts 11 at the four corners of the top of the hopper body 6. This four-point positioning method can effectively prevent the connecting frame 13 from tilting or jamming under the drive of the cylinder 10, ensuring that the scraper 18 can rise and fall vertically along the predetermined trajectory. To prevent the connecting frame 13 from slipping and to limit the end point of the stroke, a limiting block 12 is provided at the top of the limiting post 11. The cross-sectional dimension of the limiting block 12 is larger than that of the limiting post 11. When the connecting frame 13 slides upward to the highest point, the top surface of the connecting frame 13 contacts the bottom surface of the limiting block 12 and is thus blocked, ensuring that the scraper 18 assembly always operates within a safe working range.

[0025] To enhance the overall stability of the device and facilitate installation, fixing plates 7 are provided on the outer walls of both sides of the hopper body 6. The fixing plates 7 have internal threaded holes and are equipped with bolts 8. By rotating the bolts 8, the top of the bolts is pressed against the external support structure, or the bolts 8 are passed through the fixing plates 7 to connect with other supports, thereby achieving a firm installation of the hopper body 6 and the entire anti-blocking vibration device.

[0026] For ease of operation and control, a control panel 2 is provided on the front side of the discharge port 1. The control panel 2 integrates a control circuit connected to the vibrating motor 5 and the cylinder 10. A control button 3 is provided at the bottom of the control panel 2. The start, stop and frequency of the vibrating motor 5 and the extension and retraction of the cylinder 10 can be controlled independently through the control button 3, so as to achieve flexible handling for different blockage situations.

[0027] Working principle: When assembling the anti-blocking vibration device for concentrate hopper, a control panel 2 is set on the front side of the discharge port 1. The output frequency of the components can be observed through the control panel 2. A control button 3 is set at the bottom of the control panel 2. Other components can be controlled by the control button 3.

[0028] A hopper body 6 is provided at the top of the discharge port 1, and an installation plate 4 is fixed on the front side of the hopper body 6. A vibration motor 5 is fixed on one side of the installation plate 4. The high-frequency vibration wave generated by the vibration motor 5 is transmitted to the material inside the hopper body 6 to destroy the solidified structure, thereby reliably clearing the blockage.

[0029] Fixing plates 7 are provided on the left and right sides of the hopper body 6. Bolts 8 are threadedly connected to the inner side of the fixing plates 7. The device is fixed in a suitable position by using bolts 8 and fixing plates 7. Cylinders 10 are fixed at the top left and right sides of the hopper body 6. Cylinders 10 are used to control other components. Limiting posts 11 are fixed at the four corners of the top of the hopper body 6. Limiting blocks 12 are fixed at the top of the limiting posts 11. The range of movement of the components on the outer surface of the limiting posts 11 can be limited by the limiting blocks 12.

[0030] Positioning holes 14 are provided at the four corners of the connecting frame 13. The connecting frame 13 is slidably connected to the outer surface of the limiting post 11 using the positioning holes 14. Connecting plates 15 are fixed on the four sides of the bottom of the connecting frame 13. Push plates 16 are fixed on the bottom of the connecting plates 15. The output ends of cylinders 10 are fixedly connected to the bottom of the left and right sides of the connecting frame 13. The connecting frame 13 is controlled to slide up and down by starting the cylinders 10. At the same time, the connecting plates 15 and push plates 16 also move accordingly.

[0031] A fixing groove 19 is provided at the bottom of the push plate 16. The fixing groove 19 is used to fix other components. One end of multiple springs 17 is fixed inside the fixing groove 19. Then, the scraper 18 is fixed to the other end of the spring 17. The scraper 18 can be reset by the spring 17. A feed inlet 9 is provided at the top of the hopper body 6. The material is poured in through the feed inlet 9. The device can not only destroy the solidified structure of the material through high-frequency vibration waves, but also clean the easily solidified parts at the bottom of the hopper body 6.
