Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology for metal processing, and in particular to a two-stage dynamic collection device for cutting fumes. Background Technology

[0002] When using a gantry CNC cutting machine for material cutting, the dust spreads rapidly. Plasma cutting of metal composite plates (such as titanium plates and stainless steel composite plates) generates high-temperature, high-concentration dust (containing metal particles, oxides, and toxic gases). Traditional bottom-filled dust collection devices and fixed dust collection devices cannot collect dust in real time along with the cutting point, resulting in low collection efficiency and limited coverage of a single dust collection port. Dust easily escapes into the workshop, leading to a deterioration of the working environment and harming the health of operators. Secondary pollution and residual dust settle in the workshop, making cleaning difficult. Long-term accumulation affects equipment lifespan and product cleanliness. It is necessary to solve the problem of cutting dust. Therefore, a two-stage dynamic collection device for cutting dust was designed. Utility Model Content

[0005] The gantry CNC cutting machine is equipped with a movable roof.

[0006] The canopy includes multiple frames, each with a folding rod fixed between them. Each frame has a flue pipe fitted and fixed to its side wall, and each flue pipe has a T-joint fixed to its port. Corrugated telescopic pipes are fixed between the T-joints. The surface of the frames is covered with a canopy cloth, and supports are fixed to the side walls of the frames at both ends.

[0021] Reference Figure 1-4A dual-stage dynamic collection device for cutting fumes includes a gantry CNC cutting machine 1, a fume hood 2 fitted on the cutting end surface of the gantry CNC cutting machine 1, a drag chain conduit 3 fixed on the upper surface of the gantry frame of the gantry CNC cutting machine 1, a linear module 4 fixed on the side wall of the gantry CNC cutting machine 1, a moving plate of the linear module 4 fixed to one end of the drag chain conduit 3, an exhaust pipe 5 arranged inside the drag chain conduit 3, and one end of the exhaust pipe 5 fixed to the surface of the fume hood 2.

[0022] The gantry CNC cutting machine 1 is equipped with a movable canopy 6 on the outside. The canopy 6 has an arched structure, which can better concentrate smoke and dust.

[0023] The canopy 6 includes multiple frames 61, with folding rods 62 fixed between each frame 61. A flue pipe 63 is fitted and fixed to the side wall of each frame 61, and a T-joint 64 is fixed to the end of each flue pipe 63. Corrugated expansion joints 65 are fixed between the T-joints 64. The surface of the frames 61 is covered with a canopy cloth 66, and brackets 67 are fixed to the side walls of the frames 61 at both ends.

[0024] A tee joint 64 at one end is fixed with a main exhaust pipe 68, and a tee joint 64 at the other end is fixed with a sealing plate, thus forming a complete air duct.

[0025] Each flue pipe 63 has multiple smoke inlets 631 fixed on its surface. The smoke inlets 631 are distributed in a herringbone pattern, and are arranged in a reasonable and efficient manner according to the upward trend of smoke and dust.

[0026] The side wall of the frame 61 is fixed with a plurality of fitting rings 611 for fitting and fixing the smoke inlet 631, and the surface of the canopy 66 is provided with a plurality of round holes 661 for fitting the smoke inlet 631.

[0027] Rollers 671 are symmetrically and movably installed on the bottom of each bracket 67.

[0028] The end of the drag chain conduit 3 away from the fume hood 2 is provided with an interface 31 for connecting to the exhaust pipe 5.

[0029] It also includes two negative pressure pumps, referred to here as the first negative pressure pump and the second negative pressure pump. The first negative pressure pump is connected to the suction pipe 5, and the second negative pressure pump is connected to the main exhaust pipe 68.

[0030] Before using this device, first hoist the plate to be cut onto the cutting frame surface of the gantry CNC cutting machine 1, move and unfold the canopy 6 so that the top covers the entire gantry CNC cutting machine 1, connect the interface 31 of the exhaust pipe 5 to the input end of the first negative pressure pump and start the first negative pressure pump, connect the main exhaust pipe 68 to the input end of the second negative pressure pump and start the second negative pressure pump;

[0031] During the cutting operation, the fume hood 2 moves along with the cutting end of the gantry CNC cutting machine 1 to extract the fumes generated during cutting. The synchronous linear module 4 adjusts horizontally according to the position of the fume hood 2, thereby driving the drag chain conduit 3 to move synchronously to prevent the exhaust pipe 5 from being pulled off. For the fumes escaping from the fume hood 2, a negative pressure space is formed at the top of the canopy 6 due to the exhaust, and the fumes rise naturally and are extracted by the herringbone-shaped exhaust ports 631 at the top of the canopy 6, thus realizing bipolar dynamic fume collection.
