Laser cutting machine dust collector equipment cartridge dust collector advantages.
1. Advanced cartridge technology saves cost: Using Donaldson Uitra-Web cartridge, saving electricity cost up to 50%.
2. Pulse cleaning technology: using Donaldson Extralife? pulse cleaning technology, cleaning efficiency is higher, and can extend the life of the cartridge by more than 20%.
3.0.3μm filtration precision: the fume and dust produced by laser cutting is generally between 0.5~0.3μm, the filtration effect of nano-fiber filter material on this kind of dust can be high.
4. Flame retardant filter material: using Donaldson flame retardant filter material, can be effective flame retardant treatment for the sparks entering into the dust collector to prevent equipment from catching fire.
5. Authoritative certification escort: each device is subject to strict quality inspection before leaving the factory, in line with environmental acceptance standards, quality and safety is guaranteed.
Plasma laser cutting dust collector draws in contaminated dust through the side air inlet, and the dust entering the equipment cavity enters the net purification room through the impact spark pretreatment system. It ensures that the dangerous dust entering the equipment chamber is effectively prevented.
The dust entering the chamber is blocked by the filtration system. The filter is made of imported flame retardant nano material, which makes the dust form clumps on the surface of the filter material.
The caked dust forms pressure on the surface of the filter material, and the dust is knocked down to the dust collection box by the pulse dust cleaning system. The purified air is discharged directly through the upper end of the air box, thus achieving purification. Energy-saving operation is achieved through intelligent frequency conversion technology, and suitable power is selected according to customer's site working conditions.
Laser cutting machine dust collector equipment working principle
1、Turn on the power and compressed air, press the switch button, the induced draft fan starts and the dust collector begins to work.
2, sparks splash laser cutting fumes, under the power of the induced draft fan, into the dust collector inlet.
3、After the air inlet, the sparking soot first enters the spark catcher, whose labyrinth type construction principle makes the sparks automatically extinguished by repeated collisions and fall into the ash hopper.
4, then into the surface of the filter cartridge, due to the sudden expansion of the airflow cross-section and the role of the airflow distribution plate, the wind speed plummets, part of the coarse particles in the airflow under the action of wind power and inertia force collision, natural settlement to the bottom of the dust collection bucket; particle size fine, small density of dust particles, through the combined effect of diffusion and sieve filter, deposited on the outer surface of the filter cartridge filter media and intercepted.
5、Clean gas penetrates through the filter media and is discharged from the inner wall of the filter cartridge and enters the clean room.
6、The air in the clean room is directly discharged in the workshop by the fan, without emission chimney.
7、The resistance of the filter element cartridge increases with the increase of the thickness of the dust accumulation layer on the surface of the filter media.
8、Blowing control method can be divided into differential pressure control, timing control, manual control. The pointer type differential pressure instrument will monitor the differential pressure of the filter cartridge in real time, which is intuitive and readable. The pulse control instrument will automatically open and close the valve and open the compressed air blowing to clear the dust.
9、At this time, the pulse power is instantly turned on, the electromagnetic pulse valve opens, and compressed air of more than 4 kg pressure is instantly introduced into the surrounding air as a sufficient source of secondary amplification, and a high pressure blowing into the canister. Make the wrinkled cartridge instantly expand and deform and bulge, and produce vibration, under the action of high pressure pulse airflow, the dust attached to the outer surface of the cartridge is swept away and falls into the dust collection box of the dust hopper at the bottom of the dust collector.
10、After the dust cleaning is finished, the electromagnetic pulse valve closes, the dust on the outer surface of the filter media is cleared, the resistance becomes smaller, the filter media gets regenerated and resumes the function of intercepting dust again. When the resistance rises, the dust cleaning and regeneration work will be cycled automatically again.
Plasma cutting machine dust removal system, plasma cutting is a technology that uses plasma arc for metal cutting. Its temperature is up to about 2x104°C, which can make metal materials melt or vaporize instantly. Plasma cutting can be performed on metals that are resistant to high temperatures and have good thermal conductivity for easy oxidation, such as carbon steel, stainless steel, aluminum and aluminum alloys, copper, etc.
Plasma cutting produces fumes similar to welding fumes, with larger amounts of fumes containing harmful gases and tiny dust particles such as CO, C2, H2, 3, Nx and hydrocarbons.
The plasma cutting machine dust collection system is selected from the cutting arm following dust collection system and two-stage dust filter purifier device, and has achieved satisfactory results. The main structure and process of dust collection system: The dust collection system of CNC plasma cutting machine is following dust collection type. When the dust collection system works, the dust collection hood only controls the cutting part of the cutting platform and always ensures that the air is extracted from the cutting part of the cutting head, i.e. the part that generates fumes. The cutting fume first passes through a primary cyclone dust collector to deal with the larger particles, and then passes through a secondary cartridge type high efficiency fume cleaner to deal with the more harmful breathing dust. The system uses small air volume, and the production of dust hood is relatively simple, the overall investment cost is small, and the dust removal efficiency is high. The air treated by the dust collector is discharged to the standard through a 15.5m high exhaust stack.
Plasma cutting machine dust collector uses high efficiency filter cartridge as filter element. The filter cartridge must be made of a PTFE film, whose tiny sieve pores can block most of the submicron dust particles and form a permeable dust barrier cake on the surface of the filter material, which can block most of the dust particles. The filter cartridge is equipped with an automatic back-blowing mechanism to ensure that the dust can be effectively removed in time under the blowing of compressed air to improve the purification effect and the service life of the filter material.
Plasma cutting machine dust collection method: dust airflow through the fan generated by the negative pressure airflow through the duct into the dust collector first through the spark catcher filter sparks and large particles, and then through the filter cartridge filter separation to the clean room, completed by the fan action. The dust is blocked by the cartridge on its surface, when the blocked dust is continuously deposited on the surface of the cartridge, the pressure difference between inside and outside of the cartridge is also increasing, when the pressure difference reaches the pre-set value, the solenoid valve controlling the compressed air is opened, the compressed air flows into the back-blowing cleaning system through the pipe, and is instantly sprayed to the inner surface of the cartridge through the cleaning pipe of the cleaning mechanism, so that the dust particles deposited on the cartridge will fall off the surface of the cartridge under the action of high pressure airflow. The dust particles deposited on the cartridge will fall off from the surface of the cartridge under the action of high pressure airflow, so that the whole surface of the cartridge will be cleaned. The purified air (blue) is discharged by the air duct and fan.
One-piece cartridge purifier system structure characteristics.
One-piece purifier is composed of two major parts: filter unit and fan, of which the filter unit and fan are integrated together is the one-piece machine, and the filter unit and fan are placed separately is the split machine. One-piece machine has compact structure, simple and beautiful, small footprint, and has strong applicability to some small sites, but the one-piece machine also has its limitations, with the increase of air volume, the volume of the one-piece machine will become larger, so the purifier with large air volume should not be made into a one-piece machine, but into a split machine. The split machine is connected with the filter unit and the fan by pipeline, which is suitable for some places with large air volume demand. The fans are noise treated, and the machine has built-in muffler, which can make the noise control of the equipment operation below 75dB. Whether it is an integrated machine or a split machine, the filtered gas has reached the national emission standard.
★ PTFE-coated polyester filter cartridge.
The purifier adopts high-efficiency filter cartridge as the filtering element. The filter material chosen for this filter cartridge is different from the general traditional filter material, which has a PTFE film attached to its surface. Traditional filter materials (such as cotton, cotton satin, paper and other traditional cellulose, etc.) have a fiber gap of 5 to 60 um. When the soot passes through, part of the dust particles in the soot will enter the filter material and block the filter element; when the blocking situation gradually deteriorates and effective dust cleaning cannot be carried out, the air resistance of the filter element will rise and the air flow that can be passed will drop. If there is no automatic dust cleaning, the filtration effect will decline rapidly, but the surface of the filter material used in this series of purifiers is equipped with a layer of PTFE film, whose tiny sieve can block most of the submicron dust particles; submicron dust particles gather on the surface of the filter material and form a permeable dust barrier cake, most of the dust particles are blocked on the outer surface of the filter material and cannot enter the inside of the filter material, which can be removed effectively in time under the blowing of compressed air. The filter media has a high filtration efficiency, at least 3 to 5 times higher than the traditional filter media, for ≥0.1μm soot filtration efficiency ≥99.99%; and the service life is more than 2 times higher than the traditional filter media.
