Optical fiber laser cutting machine is one of the most common metal material processing equipment in 2020. It has the advantages of high efficiency, convenience, cost saving, etc. It is very common in metal processing enterprises. However, there is no doubt that the use of laser cutting machines to process metal chips will also cause pollutants such as smoke and dust. When such fine metal smoke particles are produced, many of them will float in the air, seriously reducing the air index, damaging the office environment, and seriously affecting the environmental protection and environmental impact assessment of enterprises. The high concentration of carbon smoke is also extremely harmful to the workers working in this area, usually causing more serious diseases, such as respiratory diseases. How to deal with the smoke caused by the laser cutting machine, and what is a more environmentally friendly way to use the laser equipment?
At present, the common laser dust removal methods are divided into dry test and wet test. The dry test is to upgrade a set of optical fiber laser cutting deduster and dedusting machine equipment. The wet test is to put the laser cutting processing technology on the river to generate a water bed laser cutting service platform, and use the flow driving force to digest and absorb smoke and dust and clean. After the comprehensive comparison of the two methods, the dry processing technology is very popular in the processing plant because of its most convenient installation and application. The smoke and dust caused by optical fiber laser cutting are concentrated under the product workpiece, so the product has a suction port under the console, which is divided into a small symmetrical suction port area.
On one side of the dedusting system software service platform, there is also a drag gas suction pipe, and the drag gas suction pipe has a suction inlet, which can be moved together with the laser cutting head. When the ash is caused, the wind speed of the ventilation duct blows the ash into the suction inlet, thus achieving the practical effect of collecting small exhaust air volume and high collection rate.
The collected dust will be sent to the dedusting server for filtering. The key structure is the same as the dedusting system software of the dust collector. The installation of filter device will intercept the smoke above 0.3M for the whole process of smoke cleaning. The dust removal efficiency of the laser is above 90%, and the effect is remarkable. Because of its cheap installation, operation and cost, it has become the most common dedusting method for optical fiber laser cutting.
