Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment, in particular to a waste gas treatment device for a magnetic material laser cutting machine. Background Art

[0002] Laser cutting machine is a kind of equipment that uses laser technology to process materials. Laser cutting machine will generate certain exhaust gas during the cutting process. The exhaust gas generated cannot be discharged directly, so it is necessary to treat the exhaust gas before discharging. Comparative document: CN 211248840 U, ​​proposes a dust-absorbing exhaust gas treatment device for laser cutting machine, which blocks and recovers larger metal blocks in the exhaust gas through a filter screen, and then the particles in the exhaust gas are slowed down and settled by the upper and lower card plates. The fan on the rear support frame accelerates the exhaust gas to make the exhaust gas collide with the coolant in the cooling pool, so that the particles still existing in the exhaust gas and the exhaust gas that can be dissolved in the coolant are absorbed, and the exhaust gas is cooled at the same time. The problem with the above technical solution is that the device directly discharges the exhaust gas after treating it, and does not detect the treated exhaust gas. Therefore, when the exhaust gas is not completely treated, it will also be discharged, which causes the exhaust gas to have a certain impact on the external environment, and may also cause safety hazards to nearby workers. Utility Model Content

[0005] Furthermore, the screening net is installed in layers of 300 mesh and 500 mesh, and part of the powder carried in the gas can be screened through the screening net to ensure the protective effect when the gas is processed.

[0006] Furthermore, the detection structure includes a gas detector, a control valve, and a transmission pipe. The bottom of the detection structure is connected to the right side of the exhaust gas box through a pipe, and the top of the detection structure is connected to the top of the right side of the exhaust gas box through a pipe. The processed gas is transmitted to the gas detector in the detection structure through the pipe.

[0007] Furthermore, a rubber sealing pad is provided on the top of the sealing tube, and the pipeline connection end can be sealed by the sealing rubber pad.

[0008] Furthermore, the detection end of the gas alarm extends to the inside of the sealed tube, and the gas alarm detects gas in the sealed tube through the detection end, and sounds an alarm when there is a gas leak.

[0009] Furthermore, a guide hole is provided on one side of the layered plate, and the gas is transmitted through the guide hole.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

The sealing tube 6 can be used to seal the connection structure between the external hose and the exhaust box 1. At the same time, the gas concentration in the sealed area is detected using the gas alarm 7 on the right. When gas leakage occurs in the connection structure, the gas alarm 7 will transmit a signal to the control terminal so that the terminal can stop the continued operation of the device in time. At the same time, the gas alarm 7 will be used to warn nearby staff so that the staff can handle it safely in time to avoid safety hazards caused by excessive gas leakage, thereby improving the safety of the device during processing. The gas transmitted to the inside of the exhaust box 1 uses the screening net 2 to filter the dust or particulate matter carried by the gas, reducing the risk of dust or particulate matter entering the equipment and causing equipment damage and road blockage. After passing through the screening net 2, the gas will enter the heat exchange tube 3. The heat exchange tube 3 transmits the gas to the reaction tube 9, and the gas is subjected to preliminary reaction treatment through the reaction tube 9. At the same time, it is transmitted to the area where the gas burner 4 is located. The exhaust gas is burned and processed by the gas burner 4, so that the harmful gas is converted into carbon dioxide and water vapor through combustion. At the same time, the converted carbon dioxide and water vapor are transmitted through the guide holes on one side of the stratification plate 8, and are transmitted to the detection structure 5 through a pipeline. The processed gas is detected by the gas detector in the detection structure 5. When it is detected that the gas has not been completely processed, the gas detector transmits a signal to the control terminal, and the control valve is controlled by the control terminal to open and close, so that the gas is transmitted to the exhaust gas box 1 for reprocessing. When the gas detection passes, it is discharged through the right side of the detection structure 5.
