How to control the smoke and dust from plasma cutting machine? What kind of dust collector to choose?

You can choose the bag type

You can also choose the filter cartridge type

The collection and treatment method of plasma cutting machine smoke, the existing plasma cutting machine is in use When cutting steel plates, due to its inherent working method, the heat and smoke generated during the cutting process are relatively large. The smoke generated will pollute the environment, and the toxic gases contained during the cutting process will harm the health of the operators. . For this reason, when performing plasma cutting, the cutting platform uses air extraction and water adsorption to deal with the smoke and dust generated during the cutting process. A set of smoke and dust collection devices are attached to the cutting workbench to collect the collected smoke and dust during work. The gas is directly transported to the central purifier for treatment and then directly discharged outdoors or indoors for recirculation. According to different smoke and dust collection directions, they are divided into side-extraction type and down-extraction type. This treatment method will not cause secondary pollution during operation and is suitable for filtering out various dusts generated during metal cutting. However, this treatment method requires a large one-time investment and a long construction period.

Taking comprehensive consideration of economic investment and treatment effect, the side-suction rubber plate sealed negative pressure dust removal method not only saves economic costs, but also greatly enhances the treatment effect. This system is equipped with an air suction port on one side of the workbench that can move with the cutting machine. An air duct is formed between several narrow grilles during cutting. This form can achieve relatively low air volume with relatively small air volume. Good dust removal effect. Moreover, the cutting platform of this type of dust removal is relatively simple, and the overall investment cost is relatively small.

Dry processing method (dry cutting) is to add a set of smoke collection devices to the cutting working platform, and transport the collected smoke directly to the smoke filtration and purification equipment, and then treat it after it reaches the standard. emission. The smoke generated by plasma cutting is basically formed under the incision of the workpiece, so the air-extraction negative pressure cutting platform has become the most common smoke collection device at present. In order to save equipment investment and improve the exhaust efficiency, that is, to achieve a higher dust collection volume with a smaller air suction volume - only the area during the cutting process is vacuumed, so the cutting platform will be vacuumed along the main guide direction of the cutting machine. Divide it into (uniform) sealed small areas, with air outlets on the sides. The working forms of the air suction port include side-suction mobile air suction port and valve-type air suction port on the side wall of the vacuum chamber.

Use side-suction rubber plate sealed negative pressure dust removal method to control the smoke and dust generated by the plasma cutting machine. The working principle of the side-suction rubber plate sealed negative pressure dust removal system:

A square suction duct is installed on one side of the cutting platform, and a sliding suction car is installed above the suction duct that can move with the cutting machine. A sealing rubber sheet is laid above the air duct. The sliding air suction trolley and cutting head are installed on the same straight line of the cutting machine along the direction of the crossbeam. The grille plate on the cutting platform and the steel plate being cut are used to form a flue gas channel. When cutting the steel plate, the cutting smoke and dust generated enters the suction port of the suction car through the flue gas channel, enters the square suction duct, and finally enters the purifier host for purification. deal with.

The square suction duct and sliding suction trolley are important components of the side-suction cutting platform. When working, the sealing belt is tightly attached to the top of the square air suction duct under the action of negative pressure in the pipeline, playing a sealing role. At the sliding suction car, there are two rollers in the car, and the sealing belt is pushed up when passing through the car. In this way, the smoke enters the square suction duct through the car's suction port and enters the purifier for purification. Characteristics of the side-suction cutting platform dust removal system

The side-suction cutting platform has been widely used in recent years, and has obvious effects on dust removal applications for cutting platforms above 3 meters.
