[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0022] Laser processing fume and dust environmental protection treatment device, such as figure 1 As shown, it includes a fume collection module 14 and a fume processor 9, and the fume collection module 14 is connected to the air intake pipe 1 of the fume processor 9 through a conveying pipe. The soot generated by the operation of the laser generator 13 is collected by the soot collection module 4 and then sent to the soot processor 9 for processing, and then discharged without pollution. An exhaust fan is installed at the intake pipe 1 of the fume processor 9, and a control unit 10 is installed on the fume processor 9. When the processor 9 is not turned on, the laser generator 9 does not work; when the soot processor 9 is turned on, the laser generator 13 can work, which ensures that the smoke and dust generated by laser processing will not be directly discharged into the air. in the air. Preferably, the control unit 10 is installed on the outer wall of the filter chamber 7 of the fume processor 9, the control unit 10 is connected to the exhaust fan through a control wire, and determines the smoke and dust by monitoring the opening or closing of the exhaust fan Whether the processor is turned on. Therein, the control unit 10 can use conventional control elements. The fume collecting module 14 includes a dust collecting hood installed above the laser generator, and the dust collecting hood is connected with the air intake pipe 1 through a pipe. A dust collector is installed on the dust hood.
[0023] like figure 2 As shown, the soot processor 9 includes a positive electrode processing chamber 3, a negative electrode processing chamber 4 and a filter chamber 7. The soot inlet of the positive electrode electrical processing chamber 3 is connected to the air intake pipe 1, and the positive electrode electrical processing chamber 2 The soot outlet is connected to the soot inlet of the negative electrode processing chamber 4 , the soot outlet of the negative electrode processing chamber 4 is connected to the soot inlet of the filter chamber 7 , and the soot outlet of the filter chamber 7 is connected to the exhaust port 2 . Several positive electrodes 31 are arranged in the positive electrode processing chamber 3 for neutralizing the negative charge static electricity in the dust gas. A number of negative electrodes 41 are arranged in the negative electrode processing chamber 4 for neutralizing the positive charge static electricity in the dust gas, and a filter element 71 is installed in the filter chamber 7 for filtering harmful substances. The treated dust air is discharged from the exhaust port 2, and it is not easy to pollute the air. A fixing frame 8 is arranged outside the filter chamber 7 for supporting the filter chamber 7 . An insulating plate 5 is arranged between the negative electrode processing chamber 4 and the filter chamber 7 to avoid safety accidents such as electric shock. At least one guide plate 6 is installed between the negative electrode processing chamber 4 and the channel of the filter chamber 7 for introducing smoke and dust from the side of the filter chamber 7 to form a swirling flow and improve the filtering efficiency.
[0024] like image 3 and Figure 4 As shown, a plurality of substrates 31 are staggered in the positive electrode processing chamber 3 , and a plurality of positive electrodes 32 are arranged on the substrates 31 . The arrangement density of the positive electrodes 32 on the substrate is 6-9 per square centimeter. Preferably, the arrangement density of the positive electrodes 32 on the substrate 31 is 8 per square centimeter. The incoming dust air is blown into the positive electrode 32, and then enters the other substrate 31 on one side, and is processed by the second-stage positive electrode 32, which can effectively remove negatively charged static electricity. The height of the positive electrode is 2-3cm, and the effect of removing static electricity is the best.
[0025] The structure of the negative electrode processing chamber 4 is the same as that of the positive electrode processing chamber 3 .
[0026] like Figure 5 As shown, at least two filter elements 71 are installed in the filter chamber 7, and they are arranged in sequence according to the direction in which the dust and air enter. The filter diameter of the first-stage filter element is 100-200 mesh. The filter diameter of the second-stage filter element is 200-300 mesh. The distance between the first-stage filter element and the second-stage filter element is 10-30 cm, preferably 20 cm, which can form a buffer cavity, which is beneficial to improve the filtering effect.
[0027] The laser processing smoke and dust environmental protection treatment method is based on the laser processing smoke and dust environmental protection treatment device. When the smoke and dust processor is not turned on, the laser generator does not work; when the smoke and dust processor is turned on, the laser generator can work; The smoke and dust are collected by the dust collecting hood and then enter the smoke and dust processor from the inlet pipe through the pipeline for processing. The smoke and dust are positively neutralized in the positive electrode processing chamber, and then enter the negative electrode processing chamber for negative electricity neutralization, and finally filter through the filter chamber. . Among them, the smoke flow should be controlled at 4-5m 3 /minute.
[0028] The above are only the preferred embodiments of the patent of the present invention, but the protection scope of the patent of the present invention is not limited to this. The equivalent replacement or modification of the technical solution and its invention patent concept shall fall within the protection scope of the invention patent.
