Description

Technical Field

[0001] This utility model relates to the field of construction waste recycling technology, and more specifically, to a dust suppression device for construction waste recycling. Background Technology

[0002] In construction waste recycling operations, the crushing and sorting processes generate a large amount of dust. This dust, suspended in the air, not only reduces visibility at construction sites and disrupts normal work processes, but also causes serious damage to the respiratory systems of construction workers. Long-term exposure can easily lead to occupational diseases such as pneumoconiosis. At the same time, the large amount of dust spreading into the surrounding environment causes air pollution, affects the quality of life of nearby residents, and raises environmental issues. Currently, most dust suppression equipment for construction waste recycling on the market uses fixed spray devices or single-direction spray systems. Fixed spray devices have a fixed coverage area and cannot be adjusted according to changes in the size of the waste recycling equipment and the operating environment. When dealing with large recycling equipment or different types of processing devices, it is difficult to achieve comprehensive and effective dust suppression. Single-direction spray systems lack flexibility and cannot suppress dust generated from different angles, resulting in poor dust suppression effects. Therefore, we propose a dust suppression device for construction waste recycling. Utility Model Content

Multiple atomizing nozzles are fixedly connected to the side of the two opening and closing plates that are relatively close to each other and to the bottom of the top plate. The gear rings are respectively fixedly connected to the outer wall of the corresponding connecting shaft; The drive assembly is used to drive the two connecting shafts to rotate in opposite directions, thereby driving the two opening and closing plates to rotate.

[0005] Preferably, the dust suppression equipment further includes a mounting frame, on both sides of the inner wall of the mounting frame, a sliding groove is fixedly connected to the inner wall of each sliding groove, and a sliding plate is slidably connected to the outer wall of each sliding rod.

[0006] Preferably, a bracket is fixedly connected to the top of the top plate, and the bracket is fixedly connected to the slide plate on both sides.

[0007] Preferably, a hydraulic cylinder is fixedly connected to the inner wall of the mounting bracket, and the output end of the hydraulic cylinder is fixedly connected to the bracket.

[0008] Preferably, a mounting plate is fixedly connected to the inner wall of the mounting bracket, the output end of the hydraulic cylinder passes through the mounting plate and extends to its outer side, and a stepper motor is fixedly connected to the outer wall of the mounting plate.

[0009] Preferably, the drive assembly includes two support plates, which are fixedly connected to the top of the top plate. An output shaft is rotatably connected between the two support plates. Cylindrical gears are fixedly connected to the outer walls of the output shaft, and the cylindrical gears mesh with gear rings respectively.

[0010] Preferably, the drive assembly further includes a drive shaft, with a first bushing rotatably connected to both ends of the drive shaft. The first bushing is rotatably connected to the corresponding output shaft. A first bevel gear is fixedly connected to the ends of both output shafts.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0017] like Figure 1 , Figure 3 and Figure 5 As shown, a dust suppression device for construction waste recycling includes a top plate 9, two gear rings 12, and a drive assembly. The inner walls on both sides of the top plate 9 are rotatably connected to the connecting shaft 10, and the outer walls of the connecting shaft 10 are fixedly connected to the opening and closing plate 11. Multiple atomizing nozzles 21 are fixedly connected to the side of the two opening and closing plates 11 that are relatively close to each other and to the bottom of the top plate 9. The gear rings 12 are fixedly connected to the outer walls of the corresponding connecting shafts 10; The drive assembly is used to drive the two connecting shafts 10 to rotate in opposite directions, thereby driving the two opening and closing plates 11 to rotate.

[0018] The top plate 9, connecting shaft 10, and opening / closing plate 11 form an adjustable spray frame. The connecting shaft 10 is rotated by the drive component, causing the opening / closing plate 11 to rotate. The spray angle and coverage of the atomizing nozzles 21 can be adjusted according to the size of the construction waste recycling equipment and the operating scenario. Compared with traditional fixed spray devices, this improves the adaptability of the dust suppression equipment. Multiple atomizing nozzles 21 are distributed at the bottom of the top plate 9 and inside the opening / closing plate 11, which can spray dust suppression from multiple directions, solving the problem of poor flexibility of single-direction spray systems and improving the dust suppression effect.

[0019] In this embodiment, as Figures 1-3 As shown, the dust suppression equipment also includes a mounting frame 1. Both sides of the inner wall of the mounting frame 1 are provided with sliding grooves 4. Sliding rods 5 are fixedly connected to the inner wall of the sliding grooves 4, and sliding plates 6 are slidably connected to the outer wall of the sliding rods 5.

[0020] The top plate 9 is fixedly connected to the bracket 7, and the bracket 7 is fixedly connected to the slide plate 6 on both sides.

[0021] A hydraulic cylinder 2 is fixedly connected to the inner wall of the mounting bracket 1, and the output end of the hydraulic cylinder 2 is fixedly connected to the bracket 7.

[0022] Mounting plate 3 is fixedly connected to the inner wall of mounting bracket 1. The output end of hydraulic cylinder 2 passes through mounting plate 3 and extends to its outer side. Stepper motor 8 is fixedly connected to the outer wall of mounting plate 3.

[0023] The mounting frame 1, slide 4, slide bar 5, slide plate 6, and hydraulic cylinder 2 are configured to adjust the distance of the dust suppression equipment according to the distance between different construction waste recycling equipment and the mobile vehicle.

[0024] In this embodiment, as Figure 1 and Figure 4 As shown, the drive assembly includes two support plates 13, which are fixedly connected to the top of the top plate 9. An output shaft 14 is rotatably connected between the two support plates 13. Cylindrical gears 15 are fixedly connected to the outer walls of the output shaft 14, and the cylindrical gears 15 mesh with the gear ring 12 respectively.

[0025] The drive assembly also includes a drive shaft 18, with a first bushing 17 rotatably connected to both ends of the drive shaft 18. The first bushing 17 is rotatably connected to the corresponding output shaft 14. A first bevel gear 16 is fixedly connected to the ends of both output shafts 14. A second bevel gear 20 is fixedly connected to both ends of the drive shaft 18. The second bevel gear 20 meshes with the first bevel gear 16.

[0026] A second bushing 19 is rotatably connected to the outer wall of the drive shaft 18. A third bevel gear 22 is fixedly connected to both the outer wall of the drive shaft 18 and the output end of the stepper motor 8. The two third bevel gears 22 mesh with each other, and the output end of the stepper motor 8 is rotatably connected to the second bushing 19.

[0027] The cylindrical gear 15 meshes with the gear ring 12, transmitting the rotation of the output shaft 14 to the connecting shaft 10, thereby enabling the rotation of the opening and closing plate 11. The arrangement of the first bevel gear 16, the second bevel gear 20, and the drive shaft 18 allows the two output shafts 14 to rotate synchronously in opposite directions, ensuring that the two opening and closing plates 11 rotate in opposite directions and adjust the spray angle.

[0028] Working principle: When using this dust suppression equipment, the mounting frame 1 is fixed on the mobile vehicle, which moves the entire dust suppression equipment to one side of the construction waste recycling device. The hydraulic cylinder 2 inside the mounting frame 1 is activated. The output end of the hydraulic cylinder 2 pushes the bracket 7, and the bracket 7 drives the top plate 9 to slide on the slide rod 5 via the sliding plate 6, thereby moving the top plate 9 to a position above the construction waste recycling device, allowing the dust suppression equipment to adapt to construction waste recycling devices of different heights. After the height adjustment is completed, the stepper motor 8 is started. The output end of the stepper motor 8 drives the third bevel gear 22 fixedly connected to it to rotate. The third bevel gear 22 meshes with the third bevel gear 22 on the drive shaft 18, driving the drive shaft 18 to rotate. The second bevel gears 20 at both ends of the drive shaft 18 mesh with the first bevel gear 16 at the end of the output shaft 14, driving the two output shafts 14 to rotate. The cylindrical gear 15 on the outer wall of the output shaft 14 meshes with the gear ring 12, thereby driving the connecting shaft 10 to rotate, causing the two opening and closing plates 11 to rotate in opposite directions, adjusting the angle of the opening and closing plates 11. After the opening and closing plate 11 and the top plate 9 are adjusted to the appropriate position, the water source of the atomizing nozzle 21 is turned on. The atomizing nozzle 21 sprays water atomized. During the construction waste recycling operation, the atomizing nozzle 21 sprays continuously from multiple directions to reduce dust generated at different angles.
