[0025] The following is combined with Figure 1 -Attached Figure 2 The present invention is described in further detail.

[0026] The embodiment of the present invention discloses an intelligent dust suppression device for a cantilever unloading point of a stacker. Figure 1 and Figure 2The intelligent dust suppression device for unloading point of stacker cantilever is installed at the unloading point of the end of stacker cantilever 1, and the device includes a fixed frame 2 fixedly connected to the lower end of stacker cantilever 1, and the length direction of the fixed frame 2 is the same as the length direction of the stacker cantilever 1. A dust collecting pipe 3 which can move laterally along the length direction of the fixed frame 2 is slidably installed on the fixed frame 2, and the dust collecting pipe 3 is vertically arranged and has a sandwich structure. The dust collecting pipe 3 includes a telescopic part 30 which can be vertically retracted, and a funnel part 31 in a funnel shape is connected to the top of the telescopic part 30, and the opening area of ​​the top end of the funnel part 31 is larger than the opening area of ​​the bottom end.

[0027] Reference Figure 1 and Figure 2 The bottom end of the telescopic part 30 is connected to a bulk head 32, and a support frame 33 is fixedly connected to the outer wall of the funnel part 31. A pulley 34 is installed at the end of the support frame 33, and the pulley 34 is rollingly connected to the track of the fixed frame 2. The left and right sides of the funnel part 31 are respectively vertically provided with a lifting rope 35 that is wound by a winch. The bottom end of the lifting rope 35 is connected to the bulk head 32. The winch and the lifting rope 35 form a lifting assembly. By controlling the winding or releasing of the lifting rope 35, the bulk head 32 can be driven to move up and down, thereby driving the telescopic part 30 to extend or contract. In the process of loading and unloading materials, the bulk head 32 can be dynamically controlled to rise as the height of the material pile increases, which is convenient for operators to load goods and can ensure personnel safety.

[0028] Reference Figure 1 and Figure 2 The fixed frame 2 is provided with a translation mechanism 4 for driving the dust receiving pipe 3 to move horizontally. The translation mechanism 4 includes a driving motor 40 installed at one end of the fixed frame 2. A driving sprocket 41 is installed on the output shaft of the driving motor 40. A driven sprocket 42 is rotatably connected to the other end of the fixed frame 2. A chain 43 is meshed between the driven sprocket 42 and the driving sprocket 41. The outer wall of the funnel portion 31 is connected to the chain 43. The driving motor 40 transmits power to the dust receiving pipe 3 through the driving sprocket 41, the driven sprocket 42 and the chain 43 in sequence. The movement of the chain 43 can drive the dust receiving pipe 3 to move synchronously.

[0029] Reference Figure 1 and Figure 2 A lifting cover track 5 is vertically fixed on the top of the fixed frame 2, and a lifting cover 6 is vertically slidably installed on the lifting cover track 5. The lifting cover 6 is L-shaped and cylindrical, and one end of the lifting cover 6 opens toward the drop point of the belt conveyor, and the other end of the lifting cover 6 opens toward the funnel part 31. A telescopic member 7 is vertically installed between the top of the lifting cover 6 and the top of the lifting cover track 5. The telescopic member 7 in this embodiment is an electric push rod, and a cylinder or a hydraulic cylinder can also be used in other embodiments. When the lifting cover 6 needs to be used, the telescopic member 7 extends and drives the lifting cover 6 to move downward, so that one end of the lifting cover 6 is aligned with the discharge port of the belt conveyor, and the other end is connected with the top of the telescopic part 30.

[0030] Reference Figure 1 and Figure 2 The device also includes a dust removal mechanism 8, which includes a dust collector 80 and a dust removal pipe 81. The dust collector 80 is installed on the frame of the stacker cantilever 1. One end of the dust removal pipe 81 is connected to the dust collector 80, and the other end of the dust removal pipe 81 is connected to the dust receiving pipe 3. The middle part of the dust removal pipe 81 is set as a retractable telescopic part 2 810, so that the dust removal pipe 81 can shrink or stretch with the translation of the dust receiving pipe 3. The dust collector 80 is connected to the interlayer of the dust receiving pipe 3 through the dust removal pipe 81, and the dust enters the interlayer through the bulk head 32, and enters the dust removal mechanism 8 from bottom to top under the action of negative pressure.

[0031] The implementation principle of the intelligent unloading dust suppression device for the cantilever unloading point of the stacker in the embodiment of the present invention is as follows: when the stacker is normally loading iron ore, the dust receiving pipe 3 and the lifting cover 6 do not participate in the work. When the remaining powder needs to be processed, the operator first drives the dust receiving pipe 3 to move to the specified position through the driving motor 40, and then drives the lifting cover 6 to descend through the telescopic member 7 and close and connect with the dust receiving pipe 3.

[0032] Subsequently, the bulk head 32 is lowered to the stacking platform by the winch and the lifting rope 35, and the belt conveyor starts to transport the materials. After being output by the belt conveyor, the materials impact the inner wall of the lifting cover 6, and under the guidance of the lifting cover 6, they pass through the dust receiving pipe 3 vertically downward and fall to the stacking platform. The dust collector 80 is turned on to form a negative pressure environment in the interlayer of the dust receiving pipe 3. At this time, the raised dust is adsorbed into the interlayer and enters the dust collector 80 after passing through the dust removal pipe 81.

[0033] As the material height on the stacking platform rises, the hoist is synchronously controlled to reel in the lifting rope 35, thereby driving the bulk head 32 to rise. When the powder is unloaded, the lifting cover 6 and the dust receiving pipe 3 are controlled to move back to the original point. An automatic alarm shutdown system using a sensor, for example, can also be set in the device, which can automatically shut down when a mechanical failure occurs to avoid dangerous accidents.

[0034] The device has a reasonable design and compact structure. It can be combined with the head guard of the cantilever belt conveyor. It has functions such as electric lifting, automatic positioning, automatic alarm and shutdown. It uses the principle of aerodynamics to absorb and filter dust to achieve dust suppression. It can be widely used in the field of bulk cargo loading and unloading due to its simple operation and convenient maintenance.

[0035] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
