Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collector technology, specifically to a dust collector airflow control device. Background Technology
[0002] The main dust collector of the sintered finished ore bins and silos is responsible for dust removal from the conveyor belts of the finished product building, SK201 conveyor belt, SK202 conveyor belt, CP01 transfer station, CP02 transfer station, and CP03 transfer station. Some dust collector hoods do not have valves installed, while others have manual valves. Even when manual valves are installed, their locations are generally inconvenient for personnel to operate, making it impossible to safely and effectively open and close the valves on site. This results in a waste of airflow from the main dust collector when the SK201 conveyor belt, SK202 conveyor belt, CP02 transfer station, and CP03 transfer station are not working. Utility Model Content
[0003] This utility model addresses the shortcomings of existing technologies by providing a dust collector airflow control device.
[0004] This utility model is achieved through the following technical solution: a dust collector airflow control device is provided, including a control box. One end of the control box is connected to the main air duct of the dust collector, and the other end of the control box is connected to a normally open suction pipe and a plurality of adjustable suction pipes arranged in a row. A plurality of rotating shafts located on one side of the adjustable suction pipes are axially connected inside the control box. The rotating shafts extend along the arrangement direction of the plurality of adjustable suction pipes. A valve plate adapted to the end of the adjustable suction pipe is fixedly connected to the rotating shaft. The end of the rotating shaft extends out of the control box and the plurality of rotating shafts are sequentially sleeved. A drive mechanism for driving the rotating shafts to rotate is installed outside the control box.
[0005] In this design, a drive mechanism rotates the shaft, thereby enabling the corresponding opening and closing of the air intake pipe through the valve plate. Multiple shafts are connected in sequence, making the structure compact and facilitating airflow.
[0006] As an optimization, four adjustable suction pipes are provided, and two normally open suction pipes are provided, located on both sides of a row of adjustable suction pipes. The four adjustable suction pipes correspond to the SK201 belt, SK202 belt, CP02 transfer station, and CP03 transfer station in this application, and the two normally open suction pipes correspond to the finished product building belt and CP01 transfer station.
[0007] As an optimization, the drive mechanism includes a worm gear fixed to the end of the rotating shaft and a worm shaft connected to the outside of the control box. A gear is fixed to the worm shaft, and a cylinder is fixed to the outside of the control box. A rack that meshes with the gear is fixed to the telescopic shaft of the cylinder. In this solution, the rotating shaft is rotated by the cylinder driving the rack, which in turn drives the worm shaft, which in turn drives the worm gear. The worm gear and worm wheel have self-locking characteristics, ensuring the stability and reliability of the valve opening after adjustment, and effectively preventing the dust removal effect from being affected by valve malfunction.
[0008] As an optimization, multiple gears are staggered along the length of the worm, thus avoiding interference.
[0009] As an optimization, a drive mechanism support plate is fixedly connected to the outside of the control box, and a rack guide seat is fixedly connected to the drive mechanism support plate, through which the rack passes. The rack is guided by the rack guide seat.
[0010] As an optimization, a worm gear support seat is fixedly connected to the drive mechanism support plate, and the worm shaft is connected to the worm gear support seat. The worm gear is supported by the worm gear support seat.
[0011] As an optimization, the control box has an elliptical cross-section, with multiple adjustable air intake pipes arranged along the long side of the ellipse. This optimizes the structure and makes its arrangement more compact.
[0012] The beneficial effects of this utility model are as follows: This utility model provides a dust collector airflow control device. A rotating shaft and valve plate controlled by a drive mechanism are installed in the control box. Based on the working status of dust collection points such as the SK201 belt, SK202 belt, CP02 transfer station, and CP03 transfer station, the corresponding regulating suction pipes can be remotely opened and closed to achieve on-demand airflow distribution. This not only avoids energy waste from continuous airflow at dust collection points when the system is stopped, reducing operating costs, but also utilizes a worm gear and rack and pinion transmission mechanism with self-locking characteristics, ensuring the stability and reliability of valve opening adjustments and effectively preventing malfunctions that could affect dust collection efficiency. Furthermore, this design integrates multiple regulating mechanisms into the control box, resulting in a compact structure that facilitates centralized control, significantly improving operational safety and convenience, and ultimately achieving efficient, energy-saving, and stable operation of the dust collection system.

Detailed Implementation
[0014] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to describe the solution.
[0015] like Figures 1-5 As shown, this utility model discloses a dust collector airflow control device, including a control box 2. The control box 2 is a hollow, sealed box with a variable diameter. One end of the control box 2 with a smaller diameter is connected to the main air duct 1 of the dust collector, and the other end of the control box 2 is connected to a normally open suction pipe 4 and a plurality of adjustable suction pipes 3 arranged in a row. Both the normally open suction pipe 4 and the adjustable suction pipes 3 penetrate into the control box 2. In this embodiment, there are four adjustable suction pipes 3 and two normally open suction pipes 4, located on both sides of the row of adjustable suction pipes 3. To make the structure more compact, the cross-section of the control box 2 in this embodiment is elliptical, and the plurality of adjustable suction pipes 3 are arranged along the long side of the ellipse. Figure 2 As shown, in this embodiment, the four adjustable suction pipes 3 are arranged vertically, and the height of the control box 2 is greater than its width.
[0016] The control box 2 has multiple rotating shafts located on one side of the adjusting suction pipe 3. In this embodiment, there are four adjusting suction pipes 3 and four rotating shafts. The rotating shafts extend along the arrangement direction of the multiple adjusting suction pipes 3. In this embodiment, the rotating shafts are arranged vertically, and the upper end of the rotating shafts extends out of the control box.
[0017] Multiple rotating shafts are connected in sequence. In this embodiment, the four rotating shafts are the first rotating shaft 51, the second rotating shaft 52, the third rotating shaft 53, and the fourth rotating shaft 54.
[0018] The first rotating shaft 51 passes through the second rotating shaft 52, with the lower end of the first rotating shaft 51 passing through the lower end of the second rotating shaft 52, and the upper end of the first rotating shaft 51 passing through the upper end of the second rotating shaft 52.
[0019] The second rotating shaft 52 passes through the third rotating shaft 53, with the lower end of the second rotating shaft 52 passing through the lower end of the third rotating shaft 53, and the upper end of the second rotating shaft 52 passing through the upper end of the third rotating shaft 53.
[0020] The third rotating shaft 53 passes through the fourth rotating shaft 54, with the lower end of the third rotating shaft 53 passing through the lower end of the fourth rotating shaft 54, and the upper end of the third rotating shaft 53 passing through the upper end of the fourth rotating shaft 54.
[0021] The above configuration achieves a coaxial arrangement of the four rotating shafts, resulting in a compact structure. A valve plate 7 adapted to the end of the regulating suction pipe 3 is fixedly connected to the rotating shaft. In this embodiment, the valve plate 7 is a circular plate, one end of which is fixedly connected to the rotating shaft through the connecting plate 6. Specifically, a valve plate 7 is fixedly connected to the lower end of the first rotating shaft 51, the second rotating shaft 52, the third rotating shaft 53 and the fourth rotating shaft 54.
[0022] The control box 2 is externally equipped with a drive mechanism for rotating the shaft. In this embodiment, a drive mechanism support plate 15 is fixedly connected to the outside of the control box 2. The drive mechanism support plate 15 is a horizontally arranged steel plate. The drive mechanism includes a worm gear 8 fixedly connected to the end of the shaft and a worm 9 shafted to the outside of the control box 2. In this embodiment, a worm gear 8 is fixedly connected to the upper end of the first shaft 51, the second shaft 52, the third shaft 53, and the fourth shaft 54. The four worm gears 8 are arranged side by side, one above the other. A worm support seat 14 is fixedly connected to the drive mechanism support plate 15. The worm 9 is shafted to the worm support seat 14. The four worm 9 are arranged side by side, one above the other.
[0023] A gear 10 is fixedly connected to the worm 9, and the four worms 9 have different lengths, such as Figure 5 As shown, in order to avoid interference, the four gears 10 in this embodiment are staggered along the length of the worm 9.
[0024] A cylinder 13 is fixedly connected to the outside of the control box 2. The tail of the cylinder 13 is fixed to the drive mechanism support plate 15 via a column. A rack 11 that meshes with the gear 10 is fixedly connected to the telescopic shaft of the cylinder 13. To guide the rack 11, a rack guide seat 12 is fixedly connected to the drive mechanism support plate 15, and the rack 11 passes through the rack guide seat 12. Since the four gears 10 in this embodiment are staggered along the length direction of the worm 9, the four racks 11 are also staggered.
[0025] How to use this utility model: In use, the dust collector draws air through the main air duct 1 and is always connected to two normally open suction ducts 4 through the control box 2. In this embodiment, the two normally open suction ducts 4 are used for dust collection and removal of the finished product building conveyor belt and the CP01 transfer station, respectively.
[0026] Four adjustable suction pipes 3 are used for suction and dust removal of the SK201 belt, SK202 belt, CP02 transfer station, and CP03 transfer station, respectively. When the machine stops at a certain position and dust removal is not required, the corresponding cylinder 13 drives the rack 11 to move, which in turn drives the worm 9 to rotate through the gear 10. The worm 9 drives the corresponding rotating shaft to rotate through the worm wheel 8, thereby rotating and sealing the valve plate 7 corresponding to the adjustable suction pipe 3 onto the pipe opening, thus achieving sealing.
[0027] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here.
