Description

Technical Field

[0001] This utility model relates to a dust suppression device, specifically a smoke extraction device for cutting ductile iron pipe fittings. Background Technology

[0002] Cutting pipe fittings (especially ductile iron pipes) inevitably generates fumes. Specifically, the high temperature during cutting causes the metal material to evaporate, subsequently condensing into tiny metal particles, thus forming metallic fumes. Simultaneously, the metal reacts with oxygen to produce various oxides, such as iron oxides (FeO, Fe2O3, Fe3O4) and nickel oxides. Furthermore, if lubricants or coolants are used during cutting, these substances decompose under high temperatures, producing organic compound fumes. Moreover, if the pipe fitting surface has paint, rust-preventive coatings, or other chemicals present, these coatings may burn or volatilize during cutting, generating harmful gases and fumes.

[0003] Existing dust collection devices have several shortcomings in dealing with the fumes generated during the cutting of ductile iron pipes. Due to the complex distribution of fumes from cutting, influenced by factors such as the cutting location, cutting method, and the characteristics of the pipe itself, traditional dust collection devices struggle to precisely adjust the suction angle based on the actual dust distribution. They cannot achieve optimal suction range and angle through coordinated operation of the suction components, resulting in limited improvement in suction efficiency. Furthermore, traditional dust collection devices lack comprehensiveness and efficiency in covering the dust-generating area, making it difficult to flexibly adjust the suction position to maximize coverage of the dust-generating area. This leads to low suction efficiency and an inability to effectively remove the fumes generated during the cutting process.

[0004] In summary, there is a need for a fume extraction device for cutting ductile iron pipe fittings that can precisely and flexibly adjust the suction angle and comprehensively and efficiently cover the suction area. Utility Model Content

At the same time, the centrifugal fan 6 is connected to the dust collection mechanism 4 through the dust collection pipe 8.

[0042] Usage instructions:

[0043] First, the operator activates the lower core traveling unit 1, moving it flexibly to the vicinity of the cutting section of the cutting equipment requiring dust suppression. During the movement, careful observation of the surrounding environment is necessary to ensure safe and accurate arrival at the target location.

[0044] Once the designated position is reached, begin adjusting the height of the mast-type lifting platform 2. Operators must operate with caution, gradually raising or lowering the platform to ensure that the dust collection mechanism 4 can precisely approach the area where smoke and dust are generated by the cutting section of the cutting equipment, and to ensure that the dust collection mechanism 4 is directly overhead to obtain the optimal dust collection angle and position.

[0045] Next, the user uses an external controller to operate the rotation of the electric rotary platform 19. By precisely controlling the speed and angle of rotation, the vacuuming mechanism 4 is driven to rotate, adjusting it to a suitable position that can cover the smoke and dust area to the greatest extent, effectively improving the vacuuming effect.

[0046] Then, the user also uses an external controller to control the extension and retraction of the dustproof electric telescopic rod 15. As the dustproof electric telescopic rod 15 extends and retracts, it drives the side auxiliary vacuum shells 12 to rotate. The operator must carefully adjust the angle of the side auxiliary vacuum shells 12 according to the actual dust distribution to ensure that the central core vacuum shell 9 and the two side auxiliary vacuum shells 12 work together to form the optimal suction range and angle, thereby achieving a better suction effect.

[0047] After completing the above adjustments, start the centrifugal fan 6. The centrifugal fan 6 generates a strong suction force, which continuously draws the smoke and dust from the cutting area of ​​the cutting equipment into the dust collection mechanism 4 through the dust collection pipe 8.

[0048] During the dust collection process, the smoke and dust are rapidly drawn in through the core suction port 10 and the auxiliary suction port 13. Subsequently, the airflow carrying the smoke and dust is transported to the bag filter 5 along the dust outlet pipe 7, where it undergoes efficient filtration, thereby achieving effective collection and purification of the smoke and dust and reducing the smoke and dust pollution in the cutting section of the cutting equipment.

[0049] Precise and flexible suction angle adjustment: The extension and retraction of the dustproof electric telescopic rod 15 is controlled by an external controller, which drives the side auxiliary suction hollow shell 12 to rotate. The operator can finely adjust the angle according to the actual dust distribution, so that the central core suction hollow shell 9 and the two side auxiliary suction hollow shells 12 work together to form the best suction range and angle, greatly improving the suction effect.

[0050] Comprehensive and efficient dust collection coverage: By using an external controller to control the rotation of the electric rotary platform 19, which drives the dust collection mechanism 4 to rotate, it can be adjusted to a suitable position to maximize the coverage of the dust area, effectively enhancing the comprehensiveness and efficiency of dust collection.

[0051] Highly adaptable dust collection positioning: The height of the mast-type lifting platform 2 can be adjusted so that the dust collection mechanism 4 can accurately approach the dust generation area of ​​the cutting part of the cutting equipment and be directly above it to obtain the best dust collection position and improve the targeting of dust collection.

[0052] Excellent smoke and dust collection and purification: Smoke and dust can be quickly drawn in through the core suction port 10 and the auxiliary suction port 13. The airflow carrying the smoke and dust is transported to the bag filter 5 through the dust outlet pipe 7 for efficient filtration, thereby achieving effective collection and purification of smoke and dust and significantly reducing smoke and dust pollution in the cutting part of the cutting equipment.
