Application of cartridge dust collectors in laser cutting

1. Hazards of Laser Cutting Fumes

In the machinery manufacturing industry, laser cutting is widely used in metal cutting, automotive manufacturing, shipbuilding, aerospace, and other fields due to its high precision, speed, and automation. During metal cutting, the heating of the metal material generates a large amount of fumes, metal oxides, and harmful gases.

Firstly, the fumes and harmful gases pollute the workshop environment. The fumes particles are extremely fine, especially when cutting thin plates or performing high-power operations, where the fumes can be in the micrometer range, directly impacting worker health. Secondly, the large amount of fumes permeating the workshop reduces visibility, affecting the work of workers in other sections. Furthermore, fumes adhering to precision components such as lenses and guide rails of laser cutting equipment can affect the normal operation of the equipment, reduce cutting accuracy, shorten equipment lifespan, and increase maintenance costs for enterprises. Therefore, effective control of laser cutting fumes has become a key focus for enterprises.

  2.Application of Cartridge Dust Collectors in Laser Cutting

Cartridge dust collectors are a common type of dust removal equipment used in laser cutting, primarily for removing solid particles and dust generated during the laser cutting process.

1. Dust Collection.

The dust generated during laser cutting is collected using a collection device. This device includes: a collection hood, a square suction duct, a sliding suction trolley, and a sealing belt. During operation, the sealing belt, under the negative pressure of the duct, adheres tightly to the top of the square suction duct, providing a seal. At the sliding suction trolley, two rollers inside the trolley lift the sealing belt as it passes through. The dust then enters the square suction duct through the trolley's suction inlet and is then purified by the dust collector.

2. Cartridge dust collectors are widely used in the laser cutting industry, with the following advantages:

(1) Their core advantage lies in their high filtration accuracy, effectively capturing dust particles larger than 0.1μm, achieving efficient dust removal.

(2) The pleated filter media used in the cartridges provides a large filtration area and a small footprint, and can be customized according to the customer's site and air volume.

(3)Cartridge dust collectors are relatively easy to maintain. Filter cartridge replacement is simple and inexpensive. Each cartridge can be equipped with an individual pulse cleaning device, reducing maintenance costs.
