DETAILED DESCRIPTION
[0017] Reference Figure 1-4As shown, the utility model provides a technical solution: a smoke collection structure for a laser cutting machine, comprising a processing table 1, a laser cutting device 2 is installed on the surface of the processing table 1, and a cutting groove 3 is opened on the surface of the processing table 1, a sieve plate 4 is fixedly connected to the inner wall of the cutting groove 3, and two suction hood boxes 6 are arranged below the sieve plate 4, the two suction hood boxes 6 are respectively fixedly connected to the inner walls of both sides of the processing table 1, and one end of the suction hood box 6 is fixedly connected to an air guide pipe 7, one end of the air guide pipe 7 is fixedly connected to an exhaust pipe 11, and one end of the exhaust pipe 11 An exhaust pump 12 is fixedly connected, and the output end of the exhaust pump 12 passes through the side wall of the processing table 1 and is fixedly connected to an air supply pipe 13. One end of the air supply pipe 13 is connected to a purification component. When it is necessary to collect the smoke generated during cutting, the exhaust pump 12 is turned on, and the output end of the exhaust pump 12 absorbs the smoke generated during cutting through the exhaust pipe 11, the air guide pipe 7 and the suction hood box 6, and transports it into the purification component through the air supply pipe 13 to purify the smoke, thereby preventing the smoke from scattering and polluting the working environment, and protecting the health of the staff from harm.
[0018] Reference Figure 3 and Figure 4 As shown, in this embodiment: the purification component includes a dust removal box 14 and an activated carbon box 17, one side of the dust removal box 14 is connected to one end of the gas pipeline 13, and dust removal liquid is arranged in the dust removal box 14, the upper end of the dust removal box 14 is fixedly connected to a connecting pipe 16, and one end of the connecting pipe 16 is fixedly connected to the activated carbon box 17. When the flue gas enters the dust removal box 14 through the gas pipeline 13, the dust removal liquid in the dust removal box 14 will adsorb the fine smoke in the flue gas, so that it will be precipitated in the dust removal box 14, and at the same time, it can also absorb some harmful gases. When the flue gas enters the activated carbon layer after dust removal, the activated carbon will adsorb the harmful gases. And odor are adsorbed, so as to achieve the effect of flue gas purification. A dust removal pipe 15 is arranged in the dust removal box 14. One end of the dust removal pipe 15 is fixedly connected to one end of the gas supply pipe 13. The cross section of the dust removal pipe 15 is "S"-shaped, and a plurality of air outlet holes are provided on the surface of the dust removal pipe 15. An air outlet pipe 18 is fixedly connected to one side of the activated carbon box 17. One end of the air outlet pipe 18 passes through the side wall of the processing table 1 and is connected to the outside. By arranging the dust removal pipe 15 in the dust removal box 14, because the dust removal pipe 15 is "S"-shaped and a plurality of air outlet holes are provided on the surface, the flue gas can be fully in contact with the dust removal liquid, so that the dust removal effect is better.
[0019] Reference Figure 1 and Figure 2As shown, specifically, the interior of the processing table 1 is slidably connected with a collecting box 5, and the collecting box 5 is located below the sieve plate 4. When the workpiece is cut, large pieces of debris can pass through the sieve plate 4 and fall into the collecting box 5, thereby collecting the debris to avoid falling to the ground and causing pollution. The surface of the air duct 7 is covered with a semiconductor refrigeration sleeve 8, and the surface of the half-sleeve refrigeration sleeve is electrically connected to a wire tube 9, one end of the wire tube 9 is electrically connected to a refrigerator 10, and the refrigerator 10 is installed on the side wall of the processing table 1. When the refrigerator 10 is turned on, the semiconductor refrigeration sleeve 8 cools the air duct 7, thereby avoiding damage to the air duct 7 by high-temperature smoke, thereby achieving the purpose of protecting the air duct 7.
[0020] Working principle: when the laser cutting device 2 cuts the workpiece, the large debris generated by the cutting can remain on the surface of the sieve plate 4, and the small debris can fall into the collection box 5 through the sieve plate 4, so as to collect the debris and avoid falling to the ground and causing pollution. At the same time, the vacuum pump 12 is turned on, and the output end of the vacuum pump 12 absorbs the smoke generated during cutting through the vacuum pipe 11, the air duct 7 and the suction cover box 6, and then the refrigerator 10 is turned on to make the semiconductor refrigeration sleeve 8 cool the air duct 7, so as to avoid the high temperature smoke from damaging the air duct 7. When the air delivery pipe 13 delivers the smoke, the air duct 7 is cooled by the semiconductor refrigeration sleeve 8. After being sent into the dust removal box 14, the dust removal liquid in the dust removal box 14 will adsorb the fine smoke dust in the flue gas, thereby settling it in the dust removal box 14. At the same time, it can also absorb some harmful gases. The dust removal pipe 15 is "S"-shaped and has multiple air outlets on the surface, so that the flue gas can fully contact with the dust removal liquid, so that the dust removal effect is better. When the flue gas enters the activated carbon layer after dust removal, the activated carbon will adsorb harmful gases and odors, thereby achieving the effect of purifying the flue gas, thereby avoiding the scattering of smoke and polluting the working environment, and protecting the health of the staff from harm.
