Description

Technical Field

[0001] The utility model relates to the field of laser cutting, in particular to a partitioned exhaust duct. Background Art

[0002] As we all know, the laser cutting industry has been developing for decades. During laser cutting operations, the high temperatures required to melt and evaporate materials generate large amounts of smoke, metal particles, and harmful gases. These pollutants not only affect the quality of the working environment but can also pose a threat to the health of operators. As laser cutting processes become increasingly advanced, the requirements for dust removal are becoming increasingly stringent. To achieve this, exhaust devices are required. Traditional exhaust systems often use a unified air duct design, making it difficult to precisely extract air from different parts of the cutting area. This leads to localized smoke accumulation and low extraction efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a zoned exhaust duct to address the problem mentioned in the background art above that, as laser cutting processes become increasingly advanced, dust removal requirements are becoming increasingly stringent, and an exhaust device is therefore required to achieve this. Traditional exhaust systems often use a unified air duct design, which makes it difficult to achieve precise extraction of different parts of the cutting area, resulting in localized smoke and dust accumulation and low exhaust efficiency.

[0005] As an optimal technical solution of the present invention, both sides of the exhaust main duct close to one end of the exhaust port are fixedly connected with fixing plates, and a mounting hole is provided in the middle of the fixing plate. The fixing plate and the mounting hole facilitate the fixation of one end of the exhaust port of the exhaust main duct.

[0006] As an optimal technical solution of the present invention, the top of the upper frame is provided with several fixed feet, and the fireproof bricks are installed on the top of the fixed feet. The several fireproof bricks are evenly distributed, and the fireproof bricks improve the fireproof performance of the top of the exhaust main duct.

Bottom support frames are provided on both sides of the bottom of the herringbone cover plate, and the bottom of the reinforcement plate is connected to reinforcing ribs.

[0008] As an optimal technical solution of the present invention, reinforcement beams are fixedly connected to both sides of the bottom end of the reinforcement plate, and the end of the reinforcement beam away from the reinforcement plate is fixedly connected to the surface of the herringbone cover plate. The reinforcement plate and reinforcing ribs are used to strengthen and reinforce the herringbone cover plate.

When the air outlet on the damper is blocked by the exhaust main duct, the air inlet channel is closed, and no dust collection is performed in this area.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] There are several dampers, corresponding to several working areas inside the factory, and the dampers can be opened or closed by adjusting the cylinder. The adjusting cylinder can push and pull the push-pull block and the guide bar, so that the damper can move accordingly. When the air outlet on the damper coincides with the opening on the exhaust main duct, the air inlet channel is opened, and dust enters the exhaust main duct and is sucked away. When the air outlet on the damper is blocked by the exhaust main duct, the air inlet channel is closed, and no dust collection is performed in this area. The entire exhaust duct controls the damper by controlling the cylinder, thereby achieving the effect of separate dust removal in each area and improving the dust removal efficiency.
