Abstract
Description
Technical Field
[0001] This utility model relates to the field of chain bucket conveyor technology, specifically to a dust-control and environmentally friendly structure for chain bucket conveyors. Background Technology
[0002] Chain bucket conveyors are widely used in industries such as mining, metallurgy, and chemicals. They are particularly useful in material transport where dust is easily generated. Dust pollutes the surrounding environment, affects air quality, and prolonged exposure to dust can lead to health risks such as respiratory illnesses for workers. Therefore, dust-resistant and environmentally friendly structures are necessary when using chain bucket conveyors.
[0003] Traditional chain bucket conveyors are mostly open structures, with dust collectors fixed at the material inlet or a fixed location. Therefore, when the fan is collecting dust, the limited airflow means that dust in some areas cannot be effectively captured, reducing the dust collection efficiency. In some cases, the fan may even re-scatter the captured dust, causing secondary pollution. At the same time, when the material is discharged, the dust remaining between the materials in the hopper will drift away again, and the fan cannot remove this part of the dust, resulting in poor dust suppression. Utility Model Content
[0004] (I) Technical problems to be solved
[0005] The technical problem to be solved by this utility model is to overcome the defect of poor dust suppression effect of the above-mentioned fan and provide a dust-control and environmental protection structure for chain bucket conveyors.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.
[0029] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.
[0030] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0031] Example 1
[0032] Combined with appendix Figure 1 As shown, a dust-control and environmentally friendly structure for a chain bucket conveyor includes a housing 1. A conveyor 2 is housed inside the housing 1. Multiple conveying buckets 3 are evenly arranged on the chain of the conveyor 2. A feeding pipe 20 is connected to the top of the housing 1, facilitating the feeding of materials into the conveying buckets 3. A door 21 with a transparent window is hinged to one side of the housing 1. The door 21 is designed to open vertically, facilitating maintenance and replacement of internal components. The enclosed design of the housing 1 effectively suppresses the spread of dust.
[0033] Combined with appendix Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the bottom surface of the conveyor hopper 3 has several perforations 4. A dust collection assembly is provided between the chains of the conveyor 2. The dust collection assembly includes a dust suction hood 5 connected between the chains of the conveyor 2. A dust collection box 6 is located below the conveyor 2 inside the housing 1. A dust collection box 7 is pulled out inside the dust collection box 6. A vacuum cleaner 8 is connected to one side of the dust collection box 6. The dust suction hood 5 is connected to the dust collection box 6 through six suction pipes 9. The suction pipes 9 are arranged symmetrically on both sides of the dust suction hood 5 in groups of three. The symmetrical layout can improve the uniformity and efficiency of dust suction, so that the dust in the dust suction hood 5 is sucked into the dust collection box 7. The action of the vacuum cleaner 8 creates a negative pressure at the dust suction hood 5. At this time, the dust is sucked into the dust suction hood 5 and simultaneously guided into the dust collection box 6 by the suction pipes 9. The dust is collected in the dust collection box 7 to prevent its spread and ensure the dust suppression effect.
[0034] During dust collection, some smaller particles can leak from the hole 4 into the dust hood 5 and then be sucked into the dust collection box 6. To avoid this, in conjunction with the attached... Figures 1 to 3 As shown, the dust collection hood 5 is fitted with a filter screen 17. The dust collection hood 5 has slots 18 on its front, back, left and right inner walls. The filter screen 17 has locking blocks 19 around its perimeter that are adapted to the slots 18. A handle is provided on one side of the upper surface of the filter screen 17. The diameter of the mesh of the filter screen 17 is smaller than the diameter of the leakage hole 4, thereby blocking the material and preventing the material from entering the dust collection box 6. The filter screen 17 is fitted into the slots 18 by the locking blocks 19, making it easy to disassemble and clean.
[0035] Example 2
[0036] During the material dumping process, some dust remains in the conveyor hopper 3, so this dust needs to be treated. Based on Example 1, and in conjunction with the attached... Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, the outlet of the housing 1 is equipped with an adjustable-angle spray assembly for dust suppression. A fixed frame 10 is provided on one side of the outlet of the housing 1. A rotating shaft 11 is rotatably mounted on the fixed frame 10. A motor 12 is fixed on the outer wall of the fixed frame 10. The rotating shaft 11 is connected to the output end of the motor 12. The spray assembly is connected to the rotating shaft 11. The spray assembly includes an atomizing spray nozzle 13 fixed on the rotating shaft 11. A water tank 14 is provided on one side of the housing 1. A liquid pump 15 is provided on the water tank 14. Two liquid delivery pipes 16 are connected to the liquid pump 15. The liquid delivery pipes 16 are connected to the atomizing spray nozzle 13 and the water tank 14 respectively. The liquid delivery pipes 16 are made of flexible hose.
[0037] During the material discharge process, the liquid pump 15 sends the water in the water tank 14 to the atomizing spray nozzle 13 to spray water mist into the housing 1, thereby achieving dust suppression. The motor 12 can control the rotation of the atomizing spray nozzle 13 to adjust the atomizing spray nozzle 13 to an angle that meets the actual use scenario, so as to better suppress dust.
[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
