The composition and working principle of plasma dust removal system
In order to ensure the filtering effect under the premise of saving investment, We use the method of rounding to zero in the design, the cutting table under the pumping bench divided into several geometric size of the small chamber. Each chamber through a controlled valve and the main suction pipe integrated, the valve opening control through the cutting head mounting seat connected to the induction mechanism to achieve, so that in the cutting work with the cutting head position corresponding to the small chamber valve is always open, while the other small chamber valve is closed. In this way, the amount of air absorption is greatly reduced, thus saving equipment investment. Such a fixed type of dust removal system air volume according to the width of the cutting platform, generally to take a relatively large air volume to have a better dust removal effect. CNC cutting machine dust removal system cutting platform, exhaust pipe, efficient dust remover and control system composition.
Cutting platform by the workpiece support frame, slag bucket, platform base frame, composed. The cutting platform is divided horizontally into several different intervals, the size of which is: 1.2m x 2.0m, on both sides of its vertical has two full-length passages, and each horizontal interval of the cutting platform is connected or separated from the vertical passage. There is a slag bucket in each interval to hold the metal slag and metal scraps produced during the cutting and, if necessary, to lift the slag hopper out to remove it. There is a drain on each side of the slag bucket. The workpiece support frame is fixed to the upper part of the cutting platform to support the workpiece, and the workpiece support plate is removable and easy to replace (the grate design width of the head of the cutting platform is about 0.5m).
The platform surface in the more economical energy consumption, there is an appropriate downward wind speed to ensure that the smoke does not escape. An efficient dust remover is used to remove particles from soot and ensure that emissions meet environmental requirements. Start the ventilator before the cutting work begins, so that the air passes through the corresponding spaced workpiece in the frame position around, with the soot generated by the cut, from the position of the slag vent, into the vertical airduct, through the duct, through the efficient dust remover filter back into the atmosphere.
CNC plasma cutting machine plate coverage and exhaust volume has a great relationship, our company by average coverage of more than 50% of the design, effective cutting for 4.0m wide working platform, the wind volume is 16000m3/h, then the exhaust volume on both sides is: 16000m3/h x 2 x 32000m3/h, taking into account the airducted butterfly valve sealing problem, the final wind volume: 3500m/h.
