Abstract
Description
Technical Field
[0001] This utility model relates to the field of sintered ore technology, and more specifically, to a sintered ore screening buffer unloading device. Background Technology
[0002] The sinter screening buffer unloading device is a key piece of equipment in the sinter production process, used to classify the sinter by particle size and complete the unloading operation. It typically consists of screening equipment such as vibrating screens and fixed screens, as well as unloading and conveying equipment such as feeders and conveyor belts. Through screening, the sinter is separated according to particle size; products of qualified particle size proceed to the next process, while unqualified particles are returned for processing. The unloading device is responsible for transporting the screened material to a designated location, ensuring the smooth operation of the production process.
[0003] Publication No. (CN207143306U) discloses a sintered ore falling screening device, including a feed box, a falling lifting bucket, a lifting mechanism, an intermediate hopper, a pin, a screening lifting bucket, a screening lifting motor, and a screening machine. In this sintered ore falling screening device, the flap structure at the bottom of the falling lifting bucket automatically opens after touching the pin 2m above the intermediate hopper. The sintered ore undergoes two falling processes, effectively simulating the 4m falling process in the production field. In addition, the falling device and the screening device are connected, effectively avoiding human-caused material spillage, ensuring the accuracy of experimental data, and reducing the labor intensity of experimental personnel. The entire device features a high degree of automation, simple operation, and convenient maintenance.
[0004] However, this type of sintered ore falling screening device has the following drawbacks: it cannot buffer the material during the screening process. The material has no buffer during the falling and rolling process and directly impacts the screen and other components of the screening device. This will cause these components to bear a large impact force, accelerate the wear, deformation or even damage of the components, reduce the service life of the equipment, and increase the maintenance cost and replacement frequency of the equipment. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sinter screening buffer unloading device to solve the problem that the material cannot be buffered during the screening process in the prior art.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sinter screening buffer unloading device, comprising...
[0007] The support frame has two vibrating motors fixedly connected to its exterior. A discharge plate is fixedly connected to the drive ends of the two vibrating motors. Multiple outer shells are fixedly connected to the inner wall of the discharge plate. Pressure plates are slidably connected to the inner walls of each of the multiple outer shells. A spring is fixedly connected to the exterior of each pressure plate. A top block is fixedly connected to the end of the pressure plate away from the spring. A sieve plate is fixedly connected to the end of the top block away from the pressure plate. Multiple springs are fixedly connected to the exterior of the sieve plate. Multiple elastic elements are fixedly connected to the inner wall of the discharge plate. A discharge plate is fixedly connected to the exterior of the discharge plate. A buffer assembly for cushioning subsequent components is rotatably connected to the inner wall of the discharge plate.
[0008] The buffer assembly includes a buffer plate, both ends of which are rotatably connected to the inner wall of the unloading plate. Multiple rubber blocks are fixedly connected to the outside of the unloading plate. Multiple base plates are fixedly connected to the outside of the bracket. Springs are fixedly connected to the outside of each of the multiple base plates. A support plate is fixedly connected to the end of each spring away from the base plate. A sliding column is fixedly connected to the outside of the support plate. A sliding sleeve is fixedly connected to the outside of the base plate.
[0009] The outer side of the sliding column is slidably connected to the inner wall of the sliding sleeve, and the outer side of the support plate is in contact with the outer side of the sliding sleeve.
[0010] The screen plate is slidably connected to the inner wall of the discharge plate, and the top block is slidably connected to the inner wall of the outer shell.
[0011] The outer side of the buffer plate is in contact with the outer side of the rubber block, and the end of the support plate away from the sliding column is fixedly connected to the outer side of the unloading plate.
[0012] The end of the sieve plate away from the top block is in contact with the outside of the elastic element, and the end of the spring away from the sieve plate is fixedly connected to the inner wall of the unloading plate.
[0013] The outer side of the sieve plate is in contact with the outer side of the outer shell, and one end of the spring away from the pressure plate is fixedly connected to the inner wall of the outer shell;
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] In the above scheme, the discharge plate is driven to vibrate by starting the vibrating motor. When the discharge plate vibrates, it also drives the screen plate to vibrate. When the screen plate vibrates, it applies the vibration to spring one through the top block. Spring one will contract and release potential energy and react on the screen plate. The screen plate then transmits the force to spring two. At this time, the repeated release of potential energy by spring one and spring two makes the screen plate vibrate more violently on the basis of vibration. The elastic element can prevent the excessive vibration of the screen plate from causing rigid collisions with the components, extending the service life of the equipment and improving the vibrating screening effect while avoiding clogging of the vibrating screen.
[0016] In the above solution, by setting up a buffer component, during the process of material being put into the discharge plate, some larger materials will inevitably roll rapidly inside the discharge plate. At this time, the buffer plate will block the larger materials to prevent them from splashing out. At the same time, the buffer plate will swing under the force, and the rubber block will block the excessive swing of the buffer plate to prevent the excessive swing of the buffer plate from impacting and splashing the material, thus achieving the buffering of the material.

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0025] As attached Figure 1 To be continued Figure 5An embodiment of this utility model provides a sinter screening buffer unloading device, including...
[0026] Support frame 1 serves as the structural support for the entire device, ensuring its stability and reliability. Two vibrating motors 2 are externally fixed to support frame 1, acting as the power source and generating vibrations to provide power. A discharge plate 3 is fixedly connected to the drive ends of the two vibrating motors 2. When the vibrating motors 2 start, they drive the discharge plate 3 to vibrate. The discharge plate 3 serves to bear materials and transmit vibrations, acting as the main working area for material unloading and screening. Multiple outer shells 4 are fixedly connected to the inner wall of the discharge plate 3. These shells provide space for the installation and protection of internal components and also participate in the vibration and buffering process of the entire device. Pressure plates 5 are slidably connected to the inner walls of each of the multiple outer shells 4. These pressure plates 5 can slide within the shells 4, transmitting and buffering forces during device operation. A spring 6 is externally fixed to the pressure plate 5. The spring 6 is elastic; when subjected to external forces, it undergoes elastic deformation, storing and releasing energy, thus buffering and regulating the vibration of the device.
[0027] A top block 7 is fixedly connected to the end of the pressure plate 5 away from the spring 6. The top block 7 transmits the force of the pressure plate 5 to the screen plate 8 and provides support and guidance when the screen plate 8 vibrates. The screen plate 8 is a key component for achieving the screening function. The material vibrates on it, and materials of different particle sizes are separated through the screen holes. Multiple springs 9 are fixedly connected to the outside of the screen plate 8. The springs 9 and spring 6 work together to further enhance the vibration effect of the screen plate 8, making the screening more thorough and efficient. Multiple elastic elements 10 are fixedly connected to the inner wall of the discharge plate 3. The elastic elements 10 can buffer and limit the vibration of the screen plate 8, preventing the screen plate 8 from vibrating excessively and causing rigid collisions, thereby protecting the equipment, extending its service life, improving the vibrating screening effect, and preventing the vibrating screen from clogging. A discharge plate 11 is fixedly connected to the outside of the discharge plate 3. The discharge plate 11 guides the screened material to smoothly exit the device, completing the unloading process.
[0028] The buffer assembly includes a buffer plate 12, which is the main component of the buffer assembly. When material is placed into the discharge plate 3, it can block larger materials, playing a preliminary buffering role. The two ends of the buffer plate 12 are rotatably connected to the inner wall of the discharge plate 3. This rotatable connection allows the buffer plate 12 to swing when impacted by material, thereby absorbing and buffering the impact force. Multiple rubber blocks 13 are fixedly connected to the outside of the discharge plate 3. The rubber blocks 13 are elastic; when the buffer plate 12 swings, the rubber blocks 13 can prevent excessive swinging of the buffer plate 12, preventing excessive impact on the material and avoiding material splashing, further achieving buffer protection for the material. Multiple base plates 14 are fixedly connected to the outside of the support 1. The base plates 14 provide the mounting foundation for components such as the spring 15 and the support plate 17, ensuring the stability of the entire buffer structure. Multiple base plates 14 are fixedly connected to the outside of springs 15. When the device is working, springs 15 can absorb and buffer the vibration and impact force transmitted from the unloading plate 3, and play a role in shock absorption of the entire device.
[0029] A support plate 17 is fixedly connected to the end of spring 3 15 away from the base plate 14. The support plate 17 supports the unloading plate 3 and, under the action of spring 3 15, can move up and down with the vibration of the unloading plate 3, thus playing a role in buffering and stabilizing. A sliding column 18 is fixedly connected to the outside of the support plate 17. The sliding column 18 cooperates with the sliding sleeve 16 to guide the movement of the support plate 17, ensuring the stability and accuracy of the support plate 17 during movement. The sliding sleeve 16 is fixedly connected to the outside of the base plate 14. The sliding sleeve 16 and the sliding column 18 form a sliding pair, providing guidance and support for the movement of the support plate 17, making the entire buffer structure more stable and reliable.
[0030] The sliding column 18 is externally slidably connected to the inner wall of the sliding sleeve 16. This sliding connection allows the sliding column 18 to slide freely within the sliding sleeve 16 while ensuring the accurate movement direction of the support plate 17 and preventing deviation. The outer surface of the support plate 17 is in contact with the outer surface of the sliding sleeve 16. This contact method further enhances the stability of the support plate 17. When the support plate 17 moves, the sliding sleeve 16 can support and limit it, preventing excessive shaking of the support plate 17.
[0031] The screen plate 8 is externally slidably connected to the inner wall of the discharge plate 3. This sliding connection allows the screen plate 8 to vibrate freely within the discharge plate 3 while ensuring its relatively stable position and preventing displacement. The top block 7 is externally slidably connected to the inner wall of the outer casing 4. This sliding connection allows the top block 7 to transmit the vibration of the screen plate 8 to the spring 6, and it can also move accordingly under the action of the spring 6, ensuring the normal operation of the device.
[0032] The outer side of the buffer plate 12 is in contact with the outer side of the rubber block 13. When the buffer plate 12 swings, it will contact the rubber block 13. The rubber block 13 can buffer and limit the swing of the buffer plate 12, preventing the buffer plate 12 from swinging excessively and impacting the material. The end of the support plate 17 away from the sliding column 18 is fixedly connected to the outside of the discharge plate 3. This connection method allows the support plate 17 to provide effective support and buffer for the discharge plate 3. Under the action of the spring 3 15, it can absorb the vibration and impact force transmitted from the discharge plate 3.
[0033] The end of the sieve plate 8 furthest from the top block 7 is in contact with the outside of the elastic element 10. When the sieve plate 8 vibrates, it will contact the elastic element 10. The elastic element 10 can buffer and limit the vibration of the sieve plate 8, preventing the sieve plate 8 from vibrating excessively and colliding rigidly with other components. The end of the spring 9 furthest from the sieve plate 8 is fixedly connected to the inner wall of the discharge plate 3. When the sieve plate 8 vibrates, the spring 9 can store and release energy, enhancing the vibration effect of the sieve plate 8 and making the screening more thorough.
[0034] The outer surface of the sieve plate 8 is in contact with the outer surface of the outer casing 4. This contact allows the sieve plate 8 to transmit vibrations to the outer casing 4 when it vibrates, while the outer casing 4 also provides some support and limiting for the sieve plate 8. The end of the spring 6 away from the pressure plate 5 is fixedly connected to the inner wall of the outer casing 4. Inside the outer casing 4, the spring 6 can undergo elastic deformation under the action of the pressure plate 5, storing and releasing energy to buffer and regulate the vibration of the sieve plate 8.
[0035] The working process of this utility model is as follows:
[0036] First, the vibrating motor 2 is started to drive the unloading plate 3 to vibrate. When the unloading plate 3 vibrates, it also drives the screen plate 8 to vibrate. When the screen plate 8 vibrates, it will exert vibration on the spring 6 through the top block 7. The spring 6 will contract and release potential energy and react on the screen plate 8. The screen plate 8 will then transmit the force to the spring 9. At this time, the repeated release of potential energy by the spring 6 and the spring 9 makes the screen plate 8 vibrate more violently on the basis of vibration. The elastic element 10 can prevent the excessive vibration of the screen plate 8 from causing rigid collisions with the components, extend the service life of the equipment, improve the vibrating screening effect, and avoid clogging of the vibrating screen.
[0037] During the process of feeding materials into the discharge plate 3, some larger materials will inevitably roll rapidly inside the discharge plate 3. At this time, the buffer plate 12 will block the larger materials to prevent them from splashing out. At the same time, the buffer plate 12 will swing under the force. Then the rubber block 13 will block the excessive swing of the buffer plate 12 to prevent the excessive swing of the buffer plate 12 from impacting and splashing the materials, thus achieving the buffering of the materials.
