Dust treatment of CNC plasma cutter
In modern industrial production, CNC plasma cutting and traditional flame cutting technology, CNC plasma cutting machine technology in the process of metal plate cutting, cutting accuracy is higher, cutting speed faster, so it is increasingly widely used in the machinery industry.
Generally large CNC plasma cutting machine, when cutting steel plate will produce a large amount of soot, the soot from under the workpiece sprayed, distributed in the workshop, resulting in smoke in the workshop. The working conditions of workers are extremely poor, which not only affects the health of the staff, but also greatly reduces the labor productivity. With the resulting more and more serious pollution problems, CNC plasma cutting machine soot control is becoming more and more urgent. In order to strengthen labour protection, improve working conditions and improve labour productivity, Our company for you to provide satisfactory smoke purification system design.
The general treatment method of the soot of the CNC plasma cutting machine:
At present, there are two ways for cutting machine soot treatment: wet treatment and dry treatment.
The so-called wet treatment method is to set up a water bed under the cutting platform, so that the workpiece is in the water, under water to complete the cutting operation, so that the oxides produced by cutting are caught by water to achieve the purpose of purifying the working environment. The treatment only requires the manufacture of a water container, a one-time investment, but the treatment will result in secondary pollution (water pollution), and metal oxides in the underwater easy to bond, cleaning difficulties. And for users in the north due to the cold winter climate will make the water in the cutting platform frozen, to the cutting inconvenience, and the treatment is not suitable for aluminum, magnesium and other metal cutting dust in cutting in the cutting of explosive dust purification. Wet dust removal also has a disadvantage is that when cutting steel plate contact with water easy to rust, and underwater cutting efficiency.
Dry treatment method is also with the development of cutting machine in the constant update, the earlier use is in the cutting head to add an active suction cover, but in practical application found that due to the steel plate and cutting gap is relatively narrow, most of the soot in the lower part of the steel plate, the upper vacuum cover can not reach the effect of smoking dust
The new dry treatment is to add a set of soot capture device stoication device for the cutting work platform. After the disposal meet the standards, the discharge is. The soot that occurs in plasma cutting is basically formed below the workpiece incision, so the pumping-type negative pressure cutting platform becomes a more common soot capture device. In order to save equipment investment and improve the pumping efficiency, that is, with a small suction volume to achieve a higher amount of soot collection - only the area in the process of cutting vacuum treatment, so the cutting platform along the cutting machine main rail direction will be divided into a closed small area, side open with a vent. The working form of the suction port is the side suction type moving suction air suction port and the sidewall valve suction port of the suction chamber. Among them, the former is widely used because of its simple structure, reliable work and good dust removal effect.
