Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of conductive film glass processing, in particular to a smoke and dust purification device for laser engraving of conductive film glass. Background Art
[0002] In the field of LED light-emitting transparent glass, most conductive film glass circuits adopt the laser engraving process, and basically all engrave with the film surface facing up. During the engraving process, since the conductive film is a high-temperature vaporization process, a lot of smoke and dust will be generated. These smoke and dust not only affect the quality of continuous engraving, but also cause certain pollution to the environment and have a certain impact on human health to a certain extent. Although the amount of smoke and dust is very small, it is still worthy of attention and it is necessary to effectively treat it.
[0003] At present, many enterprises do not use smoke and dust purification devices during the engraving of conductive film glass, or in order to ensure the quality of laser engraving, they directly use the blowing method to blow the vaporized smoke and dust during the engraving process to the side. This method pollutes the environment, and the smoke and dust will fill every corner of the workshop, and the staff will directly inhale it into the body, causing certain harm to the body. Some enterprises use high-power smoke and dust treatment equipment. The suction hose is installed on the laser head, and the suction hose moves with the laser head in the XYZ direction. After using it for a period of time, the suction hose will be damaged. Moreover, the power of this high-power smoke and dust treatment equipment is mostly about several hundred watts, and the noise is relatively large during operation. It can only filter large-particle smoke and dust, and cannot filter fine particles, and the cost is relatively high. Content of the Utility Model

The inner end of the cylindrical fume filter element 2 is connected to the vertical mounting plate 5 and the inner end opening thereof communicates with the opening on the vertical mounting plate 5. The outer end of the cylindrical fume filter element 5 faces the air inlet 3 and there is a distance between them. The filter plate and the 19W turbine centrifugal fan 6 are both vertically arranged in the box body 1 and are located between the vertical mounting plate 5 and the rear end plate of the box body 1. The filter plate is adjacent to the vertical mounting plate 5, and the 19W turbine centrifugal fan 6 is adjacent to the rear end plate of the box body 1. An air outlet 7 is arranged on the rear end of the box body 1. The air inlet end of the 19W turbine centrifugal fan 6 faces the filter plate, and the air outlet end of the 19W turbine centrifugal fan 6 communicates with the air outlet 7 on the box body 1.
[0023] Among them, the filter plate includes a vertical partition 8, a U-shaped plate 9, a PM2.5 filter plate 10 and an EPE 11.
