Abstract
Description
Technical Field
[0001] This invention relates to the field of coal mine conveying equipment technology, specifically to a spring-type buffer adaptive dynamic flow guiding device. Background Technology
[0002] In coal mine washing and processing systems, belt conveyors are the core equipment for material transfer, and their stable operation is crucial. However, when coal flows down the chute wall, factors such as the chute structure and coal flow characteristics often cause the drop point to deviate, leading to belt misalignment. This problem brings a series of adverse consequences: High equipment maintenance costs: Frequent belt misalignment leads to accelerated wear on the belt edges and frequent malfunctions such as roller damage, requiring regular maintenance and adjustment, which significantly increases equipment maintenance costs; High cost of manual adjustment: In order to ensure the normal operation of the belt, it is necessary to arrange dedicated personnel to frequently check and manually adjust the position of the belt, which consumes a lot of manpower and time costs; Significant safety hazards: Belt misalignment can easily lead to material spillage, which not only wastes coal resources but may also cause serious malfunctions such as belt tearing and equipment jamming, and even threaten the personal safety of on-site personnel. Currently, there is a lack of efficient and reliable solutions to this problem, and there is an urgent need to develop a device that can effectively adjust the coal flow drop point and prevent belt misalignment. Summary of the Invention
[0003] The purpose of this invention is to provide a spring-type buffer adaptive dynamic flow guiding device that can effectively prevent belt misalignment by precisely adjusting the coal flow drop point, reduce equipment maintenance and manual adjustment costs, and improve the safety and stability of coal mine washing and beneficiation system production.
[0004] The present invention includes a buffer baffle installed on the inner side of the chute, the buffer baffle extending along the length of the chute, a rotating shaft fixedly connected to the upper part of the buffer baffle, a sleeve fitted over the rotating shaft, the rotating shaft being able to rotate within the sleeve; an elastic element fixedly provided on the outer side of the buffer baffle.
[0005] Preferably, a plurality of elastic elements are provided, which are evenly spaced on the outer surface of the buffer baffle.
[0006] Preferably, the installation position of the buffer baffle is at a vertical height of 0.4m to 0.6m from the bottom of the chute discharge port.
[0007] Preferably, a material blocking device is fixed on the inner side of the buffer baffle, and a plurality of material blocking devices are provided and spaced apart on the inner side of the buffer baffle.
[0008] Preferably, the material blocking device is a material blocking roller disposed on the surface of the buffer baffle, and the positions of the material blocking roller on the surface of the buffer baffle in both the horizontal and vertical directions are staggered.
[0009] Preferably, the material blocking device is a material blocking plate disposed on the surface of the buffer baffle, and the positions of the material blocking plate on the surface of the buffer baffle are staggered in both the horizontal and vertical directions.
[0010] Preferably, the cross-section of the baffle plate is a triangular structure that is narrow at the top and wide at the bottom.
[0011] Preferably, the material blocking device is a material blocking strip disposed on the surface of the buffer baffle, and a plurality of material blocking strips are disposed at intervals on the surface of the buffer baffle.
[0012] Preferably, the baffle bar has an upwardly curved arc structure.
[0013] Preferably, the upper side of the baffle bar is provided with a serrated structure.
[0014] In summary, the present invention has the following beneficial effects: 1. It can significantly reduce the probability of belt misalignment, effectively solve the problem of belt misalignment caused by unreasonable chute design, ensure the stable operation of belt conveyors, reduce the frequency of equipment maintenance, greatly reduce the amount of manual adjustment work, reduce maintenance costs, and significantly improve economic benefits; at the same time, it can also effectively eliminate safety hazards such as material spillage and equipment damage caused by belt misalignment, create a safe and stable production environment for coal mine washing and beneficiation systems, and reduce the risk of safety accidents. 2. A material blocking device is fixed on the inner side of the buffer baffle. The material blocking device can buffer and disperse the coal flow, resist the impact of the coal flow, make the coal flow stay on the buffer baffle for a longer time, and make the coal falling speed more moderate, so as to avoid the coal blocks falling quickly and causing a large impact on the conveyor belt. At the same time, the spaced material blocking devices can also disperse the concentrated coal flow and make it fall evenly. Attached Figure Description
[0015] Figure 1 This is a schematic diagram of the structure of a spring-type buffer adaptive dynamic flow guiding device according to the present invention; Figure 2 This is a schematic diagram of the structure of the baffle roller of the spring-type buffer adaptive dynamic flow guiding device of the present invention; Figure 3 This is a schematic diagram of the baffle plate of a spring-type buffer adaptive dynamic flow guiding device according to the present invention; Figure 4 This is a schematic diagram of the baffle bar of a spring-type buffer adaptive dynamic flow guiding device according to the present invention.
[0016] In the diagram: 1. Buffer baffle; 2. Rotating shaft; 3. Sleeve; 4. Elastic element; 5. Material stop roller; 6. Material stop plate; 7. Material stop strip. Detailed Implementation
[0017] The invention will now be further described with reference to the accompanying drawings.
[0018] The orientations mentioned in this specification are based on the orientation of the spring-type buffer adaptive dynamic flow guiding device of the present invention during normal operation, and do not limit its orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.
[0019] like Figure 1 As shown, a spring-type buffer adaptive dynamic flow guiding device includes a buffer baffle 1 installed inside the chute. The buffer baffle 1 extends along the length of the chute. A rotating shaft 2 is fixedly connected to the upper part of the buffer baffle 1. A sleeve 3 is fitted over the rotating shaft 2. The rotating shaft 2 can rotate within the sleeve 3, thereby adjusting the tilt angle of the buffer baffle 1, thereby precisely controlling the coal flow direction and guiding the coal flow back to the center drop point of the conveyor belt.
[0020] An elastic element 4 is fixedly provided on the outer surface of the buffer baffle 1. Several elastic elements 4 are provided and are evenly spaced on the outer surface of the buffer baffle 1, so that the force on the buffer baffle 1 is more uniform. When the coal flow impacts the buffer baffle 1, the elastic element 4 is compressed and generates a reaction force. This reaction force can offset the impact force of the coal flow, ensuring that the tilt angle of the buffer baffle 1 will not change significantly due to the violent impact of the coal flow, thus ensuring the stability and reliability of the device adjustment.
[0021] Furthermore, the vertical height of the installation position of the buffer baffle 1 from the bottom outlet of the chute is between 0.4m and 0.6m. This height range allows the buffer baffle 1 to effectively intercept and guide the coal flow while avoiding the impact on the coal flow guiding effect and the service life of the device due to the distance being too close or too far.
[0022] Furthermore, such as Figures 2 to 4 As shown, a material blocking device is fixed on the inner side of the buffer baffle 1. Several material blocking devices are provided and are spaced apart on the inner side of the buffer baffle 1. The material blocking device can buffer and disperse the coal flow, resist the impact of the coal flow, so that the coal flow stays on the buffer baffle 1 for a longer time and the coal falling speed is more moderate, avoiding the rapid falling of coal blocks and causing a large impact on the conveyor belt. At the same time, the spaced material blocking devices can also disperse the relatively concentrated coal flow and make it fall evenly.
[0023] like Figure 2 As shown, in one embodiment, the material blocking device is a material blocking roller 5 disposed on the surface of the buffer baffle 1. The material blocking roller 5 is staggered in both the horizontal and vertical directions on the surface of the buffer baffle 1. The staggered material blocking roller 5 can disperse and buffer the coal flow, so that it falls evenly and avoids causing a large impact on the conveyor belt.
[0024] like Figure 3As shown, in another embodiment, the material blocking device is a material blocking plate 6 disposed on the plate surface of the buffer baffle 1. The material blocking plate 6 is staggered in both the horizontal and vertical directions on the plate surface of the buffer baffle 1. The cross-section of the material blocking plate 6 is a triangular structure with a narrow upper end and a wide lower end. The special structure of the material blocking plate 6 can better disperse the concentrated coal flow and make it fall evenly.
[0025] like Figure 4 As shown, in another embodiment, the material blocking device is a material blocking strip 7 disposed on the surface of the buffer baffle 1. Several material blocking strips 7 are provided, spaced apart on the surface of the buffer baffle 1. The material blocking strip 7 has an upwardly curved arc structure, and a serrated structure is provided on its upper side. The upwardly curved arc structure of the material blocking strip 7 can disperse and buffer a relatively concentrated coal flow. The serrated structure on the material blocking strip 7 can increase friction and also has a certain dispersing effect on the coal flow. When the coal flow falls along the buffer baffle 1, it is buffered and dispersed by the material blocking strip 7, falling evenly at a slower speed, thus avoiding a large impact on the conveyor belt.
[0026] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
