Description

Technical Field

[0001] This utility model belongs to the technical field of environmental protection dust removal equipment, specifically a gantry-type environmental protection dust removal device. Background Technology

[0002] Gantry-type environmental dust collection devices are typically designed for use in large, open work areas, such as above conveyor belts, to effectively capture and remove particulate matter and harmful gases from the air raised by materials. Gantry-type environmental dust collection devices offer advantages such as a large span and wide coverage, making them particularly suitable for applications requiring efficient and stable dust collection and for large work areas.

[0003] Many existing gantry-type environmental dust collection devices typically use fixed suction ports, which are difficult to adapt to materials at different heights on the conveyor belt. Fixed-height suction ports may not effectively capture dust, resulting in poor dust collection and some dust still escaping into the air. Furthermore, when the material on the conveyor belt has an irregular shape, a single-direction or fixed-position suction port cannot fully cover the material surface, creating suction blind spots. This prevents certain parts of the material from being adequately cleaned, further reducing overall dust collection efficiency and cleanliness.

[0004] To address these issues, we provide a gantry-type environmentally friendly dust removal device. Summary of the Invention

[0005] The purpose of this invention is to address the problems in the prior art by providing a gantry-type environmentally friendly dust removal device.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A gantry-type environmental dust removal device includes a gantry frame with multiple expandable or retractable rotating frames on both sides. Each rotating frame has a dust collection component inside its outer end. The inner end of each rotating frame is rotatably connected to the gantry frame, and a positioning pin is provided between the inner end of the rotating frame and the gantry frame to limit the rotation of the rotating frame and adjust its rotation angle. Adjusting the rotation angle of the rotating frame adjusts the height of the dust collection component. The dust collection component includes a rotating plate and a dust collection trough located within the rotating plate. The end of the dust collection trough is provided with an air outlet pipe for connecting to external dust removal equipment. The rotating plate is rotatably mounted within the rotating frame, and a positioning pin is provided between the rotating plate and the rotating frame to limit the rotation of the rotating plate and adjust its rotation angle. Adjusting the rotation angle of the rotating plate adjusts the orientation of the dust collection port of the dust collection trough.

[0008] As a further optimization of this utility model, both ends of the gantry frame are fixedly provided with disc components, and the edges of the disc components are provided with a plurality of first limiting holes evenly distributed along the circumference; the inner end of the rotating frame is rotatably disposed between the two disc components, and the inner end of the rotating frame is provided with a second limiting hole that matches the first limiting hole for the insertion of a positioning pin.

[0009] As a further optimization of this utility model, both outer ends of the rotating frame are integrally formed with circular portions, and the edges of the circular portions are provided with multiple third limiting holes evenly distributed along the circumference; the rotating plate is rotatably disposed between the two circular portions, and the rotating plate is provided with a fourth limiting hole that matches the third limiting holes for the insertion of positioning pins.

[0010] As a further optimization of this utility model, the side profile of the gantry frame matches the rotating frame and the dust collection assembly to lock the rotating frame in a vertical position.

[0011] As a further optimization of this utility model, the dust collection tank is rotatably disposed between the two end plates of the rotating plate, and a plurality of elastic elements are fixedly provided on the outer side of the dust collection tank at equal intervals, and the other end of the elastic elements is fixedly connected to the rotating plate.

[0012] As a further optimization of this utility model, the end of the gantry frame is provided with a drive mechanism for simultaneously driving multiple dust collection troughs in the rotating frame to reciprocate; the drive mechanism includes an electric push rod fixed on the gantry frame, the movable end of the electric push rod is fixed with a mounting block, and the mounting block is provided with multiple pull ropes that are respectively connected to the corresponding dust collection troughs.

[0013] As a further optimization of this utility model, the mounting block is provided with a through hole for the pull rope to pass through, and the surface of the mounting block is provided with a clamping member for pressing the pull rope in the through hole.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting multiple rotatable frames and multiple rotatable dust collection components, allows the height of the dust collection components to be adjusted by adjusting the rotation angle of the frames, thus adapting to materials of different heights on the conveyor belt. The orientation of the dust collection port can also be adjusted by adjusting the rotation angle of the dust collection components, allowing the dust collection ports of different components to be adjusted to various directions, thereby aligning the dust collection ports with various aspects of the material. Whether the material is regular or irregular in shape, it can achieve comprehensive and thorough dust collection, greatly improving the coverage and thoroughness of the dust collection.

[0016] 2. This utility model, by setting up an elastic element and a driving mechanism, drives the dust collection tank to rotate back and forth at a small angle. The dust collection port can dynamically change the dust collection direction. Even for materials with extremely irregular shapes and large surface undulations, it can ensure that the dust collection port covers all corners and gaps of the material in a short time, further enhancing the ability to collect dust from all directions. It effectively makes up for the dust collection dead corners that may occur due to the complex shape of the material, and greatly improves the dust collection efficiency. Attached Figure Description

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Example 1

[0027] To address the issues that existing gantry-type environmental dust collection devices typically use fixed suction ports, which are difficult to adapt to materials at varying heights on the conveyor belt, resulting in poor dust collection efficiency, and when the material on the conveyor belt has an irregular shape, a single-direction or fixed-position suction port cannot fully cover the material surface, creating suction dead zones. This prevents certain parts of the material from being adequately dusted, further reducing overall dust collection efficiency and cleanliness. Please refer to [link / reference needed]. Figure 1 , Figure 4 This utility model provides a gantry-type environmentally friendly dust removal device, including a gantry frame 1. Multiple expandable or retractable rotating frames 2 are provided on both sides of the gantry frame 1. Each rotating frame 2 has a dust collection component 3 inside its outer end. The side profile of the gantry frame 1 matches the rotating frame 2 and the dust collection component 3 to lock the rotating frame 2 in a vertical position. The inner end of the rotating frame 2 is rotatably connected to the gantry frame 1, and a positioning pin is provided between the inner end of the rotating frame 2 and the gantry frame 1 to limit the rotation of the rotating frame 2 and adjust its rotation angle. The rotation angle is adjusted to adjust the height of the dust collection assembly 3; the dust collection assembly 3 includes a rotating plate 301 and a dust collection trough 303 located in the rotating plate 301. The end of the dust collection trough 303 is provided with an air outlet pipe 305 for connecting to an external dust removal device. The rotating plate 301 is rotatably mounted in the rotating frame 2, and a positioning pin is provided between the rotating plate 301 and the rotating frame 2 to limit the rotation of the rotating plate 301 and adjust its rotation angle. The adjustment of the rotation angle of the rotating plate 301 is adjusted to adjust the position of the dust collection port of the dust collection trough 303.

[0028] During dust collection operations, multiple rotating frames 2 can be unfolded, allowing multiple dust collection components 3 to be distributed to various positions above the conveyor belt. By performing dust collection operations at different positions above the conveyor belt, comprehensive coverage of different areas of the conveyor belt can be achieved. Furthermore, the suction ports of different dust collection components 3 can be adjusted to various directions, thereby aligning the suction ports with various aspects of the material. Whether the material is regular or irregular in shape, comprehensive and thorough dust collection can be achieved, greatly improving the coverage and thoroughness of dust collection. Moreover, when the dust collection device is not in use, it can be folded up to significantly reduce the space it occupies, facilitating other production activities in the workshop.

[0029] like Figures 2-3 As shown, both ends of the gantry frame 1 are fixedly equipped with disc components 101. Multiple first limiting holes 102 are evenly distributed along the circumference at the edge of each disc component 101. The inner end of the rotating frame 2 is rotatably positioned between the two disc components 101, and the inner end of the rotating frame 2 is provided with a second limiting hole 201 that matches the first limiting hole 102 for inserting a positioning pin. When adjusting the angle of the rotating frame 2, the positioning pin is pulled outwards. At this time, the limiting component between the rotating frame 2 and the disc component 101 is removed, and the rotating frame 2 can rotate freely to the desired angle. Then, the positioning pin is inserted between the first limiting hole 102 and the second limiting hole 201.

[0030] like Figures 3-4 As shown, both outer ends of the rotating frame 2 are integrally formed with circular portions 202. Multiple third limiting holes 203 are evenly distributed along the circumference at the edges of the circular portions 202. A rotating plate 301 is rotatably positioned between the two circular portions 202, and the rotating plate 301 has a fourth limiting hole 302 that matches the third limiting holes 203 for inserting a positioning pin. When adjusting the angle of the rotating plate 301, the positioning pin is pulled outwards. At this time, the limiting element between the rotating plate 301 and the circular portions 202 is removed, and the rotating plate 301 can rotate freely to the desired angle. Then, the positioning pin is inserted between the third limiting hole 203 and the fourth limiting hole 302.

[0031] Example 2

[0032] Based on Embodiment 1, in order to further improve the all-around dust collection capability, so that the dust collection port of the dust collection tank 303 can cover the surface of irregularly shaped materials, such as... Figures 4-6 As shown, the dust collection trough 303 is rotatably mounted between the two end plates of the rotating plate 301. Multiple equally spaced elastic elements 304 are fixedly mounted on the outer side of the dust collection trough 303. The elastic elements 304 can be springs or other objects made of elastic materials. The other end of each elastic element 304 is fixedly connected to the rotating plate 301. The end of the gantry 1 is equipped with a drive mechanism 4 for simultaneously driving the dust collection troughs 303 within multiple rotating frames 2 to reciprocate. By driving the dust collection trough 303 to reciprocate at small angles via the drive mechanism 4, the dust collection port can dynamically change its suction direction. Even for materials with extremely irregular shapes and large surface undulations, it ensures that the dust collection port covers all corners and gaps of the material in a short time, further enhancing the ability to collect dust from all directions. This effectively compensates for potential dust collection dead zones caused by the complex shape of the material, greatly improving dust collection efficiency.

[0033] The drive mechanism 4 includes an electric push rod 401 fixed on the gantry frame 1. The movable end of the electric push rod 401 is fixedly provided with a mounting block 402. The mounting block 402 is provided with multiple pull ropes 403 that are respectively connected to the corresponding dust collection tank 303. The mounting block 402 is provided with a through hole 404 for the pull ropes 403 to pass through. The surface of the mounting block 402 is provided with a clamping member 405 for clamping the pull ropes 403 in the through hole 404. The clamping member 405 allows the tension and length of the pull ropes 403 to be adjusted, so that the dust collection tank 303 can be pulled by the drive mechanism 4 under different angles of the rotating frame 2.

[0034] In use, the electric push rod 401 drives the mounting block 402 to move. The mounting block 402 pulls the dust collection tank 303 through the pull rope 403, causing the dust collection tank 303 to rotate. At the same time, the elastic element 304 is stretched. When the mounting block 402 moves in the opposite direction, the dust collection tank 303 rotates under the restoring force of the elastic element 304. Thus, when the mounting block 402 moves back and forth, the dust collection tank 303 can rotate back and forth at a certain angle. The back and forth rotation of the dust collection tank 303 will generate a certain vibration. The vibration will form an unstable airflow field around the dust collection port, which will enhance the air turbulence and help to attract dust from a distance to the vicinity of the dust collection port, thereby improving the range and efficiency of dust collection.

[0035] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
