Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, and in particular to a high-pressure exhaust dust suppression device for laser pipe cutting machines. Background Technology

[0002] During the laser tube cutting process, the large amount of dust generated not only affects the working environment and threatens the health of operators, but also contaminates the equipment, reducing the lifespan and cutting precision of the laser tube cutting machine. Traditional dust suppression devices are mostly simple in structure and have poor dust collection effect, using only a single dust suction port, making it difficult to comprehensively collect dust generated from all directions during the cutting process. This results in persistently high dust concentrations in the working area. At the same time, the filtration systems of existing dust suppression devices are usually rudimentary, mostly single-layer filters, which cannot effectively filter fine dust particles. The purified air still contains a lot of dust, which does not meet environmental protection requirements. In addition, traditional methods for fixing the tubes are not secure, which can easily cause the tubes to shake during cutting, affecting the cutting quality. Therefore, a high-pressure exhaust dust suppression device with a reasonable structure, good dust collection effect, high filtration precision, and the ability to securely fix the tubes is needed to meet the high-efficiency, environmentally friendly, and high-quality processing requirements of laser tube cutting machines.

A transverse L-shaped tube 3 is provided at the rear end of the dust collection chamber 1, the front end of the transverse L-shaped tube 3 extends into the interior of the dust collection chamber 1, an upper dust collection tube 9 is fixedly connected to the front end of the transverse L-shaped tube 3, a four-way connector 5 is fixedly connected to the other end of the transverse L-shaped tube 3, a bottom dust suction structure is provided at the lower end of the four-way connector 5, and a filter mechanism is provided at the rear end of the four-way connector 5.

[0032] The top of the upper dust collection pipe 9 is fixedly connected to the inner top wall of the dust collection chamber 1. A laser cutting port 8 is opened at the upper middle part of the dust collection chamber 1. There are two upper dust collection pipes 9, which are symmetrically distributed on both sides of the laser cutting port 8. A metal mesh 10 is provided on the side end of the upper dust collection pipe 9. The metal mesh 10 can absorb the surrounding smoke and dust to the maximum extent, thus improving the absorption effect.

[0033] The bottom dust collection mechanism includes a vertical L-shaped tube 4, a dust collection trough 11, and a lower dust collection port 12. The lower end of the four-way connector 5 is fixedly connected to the vertical L-shaped tube 4. The other end of the vertical L-shaped tube 4 extends into the interior of the dust collection chamber 1. The bottom of the dust collection chamber 1 is fixedly connected to the dust collection trough 11. The side wall of the dust collection trough 11 is fixedly connected to the lower dust collection port 12. The rear end of the lower dust collection port 12 is fixedly connected to the front end of the vertical L-shaped tube 4 to clean the dust that falls from the bottom due to gravity.

[0034] The filtration structure includes a filter pipe 6, a high-pressure exhaust fan 7, a first slot 13, a primary filter screen 14, a second slot 15, a secondary filter screen 16, a third slot 17, a tertiary filter screen 18, and bolts 21.

The tube is fixed by the upper fixing ring 19 and the lower fixing ring 20, and by the buckle 22 and the pin 23 to ensure the stability of the tube during the cutting process. When the laser tube cutting machine is working, dust will be generated in the dust removal chamber 1.

[0036] Dust-laden gas enters the filter pipe 6 through the four-way connector 5. The filter pipe 6 is equipped with a three-stage filtration structure. First, the gas enters the front of the filter pipe 6 and is initially filtered by the primary filter screen 14 at the first slot 13 to remove larger dust particles. Next, the gas enters the middle of the filter pipe 6 and is further filtered by the secondary filter screen 16 at the second slot 15 to remove smaller dust particles. Finally, the gas enters the rear of the filter pipe 6 and is further filtered by the tertiary filter screen 18 at the third slot 17 to remove finer dust particles. After three-stage filtration, the gas is connected to the high-pressure exhaust fan 7 at the upper end of the filter pipe 6 and is extracted and discharged to a designated location by the high-pressure exhaust fan 7. This achieves effective collection and filtration of dust generated during the operation of the laser tube cutting machine, reduces the dust content in the working environment, and achieves the purpose of dust reduction.
