Industrial dust collection systems are used to laser cutting and welding dust and Fumes

The pollutants generated during the cutting and welding process are metallic fumes. Since cutting (plasma or laser) and welding fumes are very fine, their particle size is only 0.38 micron or less, so these metal dust easily float and settle on the surrounding equipment, so that the electronic components of these devices The life of the electronic components of these devices will be affected, such as CNC cutting machine controller and welding equipment and other electrical equipment, such as electronic components. In addition, these fumes and dust will contaminate the entire operating environment, and affect the cutting quality of the cut parts. In addition, these metal elements and material surface elements in the high temperature effect Under the action of high temperature, these metal elements and material surface elements will produce various harmful gases and fumes which will also endanger the health of workers. It makes workers vulnerable to diseases such as lung disease and alcoholic liver.

In order to extend the service life of the equipment - to prevent the cutting dust generated during the impact of CNC cutting machine control system and other electronic components Reliability; improve product quality; protect the environment to improve working conditions; prevent various fumes and exhaust gases from harming the human body during cutting. At the source of pollution Add a fume and dust cleaning system. The fume cleaning system usually consists of a suction hood (fume table), ducts, dampers, dust collectors with spark catchers, fans and electronic control devices. The system is usually composed of suction hood (fume table), ducts, dampers, dust collector with spark catcher, fans and electric control devices.

Technical parameters

TODC-B series sink box type precipitation dust collector all-in-one

- Cartridge type dust collector is a sink box type structure, which is conducive to dust filtration and settling

- The overall footprint of the cartridge type dust collector is smaller and takes up less space on site.

- The selected filter cartridge is basically made of cloth bag with nano-coating, which intercepts all the large and small particles and blocks the large particles of abrasive dust with the micro dust on the surface, reducing wear and extending life.

TODC-B series dust collector is the first in the world to use gravity and downward air flow pattern to facilitate the self-cleaning process, the dust-containing air is fed from the bottom and discharged from the top of the other side, which is designed to realize the principle of dust flow pattern downward "inertial settling" dust removal. This makes the direction of dust flow and gravity consistent, so that the dust is easier to settle and remove, and will not be brought back to the filter cartridge.

When the dust collector is in operation, the dusty air enters the TODC-B sinker from the top inlet and passes through the canister, where the dust is collected on the outer surface of the canister. The clean air is released through the center of the cartridge to the clean air chamber and then discharged through the outlet. When the cartridge is emptied, a solid-state control timer automatically selects a pair of filters. The high pressure compressed air then rushes directly into the center of the filter cartridge and blows the dust off the surface of the filter material. The dust is blown off the surface of the filter material. The dust then follows the main airflow and falls downward into the dust hopper by gravity.

The sink-flow dust collector eliminates the problem of "secondary dust absorption" and improves dust removal efficiency.

Dust collector housing.

The standard construction is made of 7 gauge (5 mm thick) and 10 gauge steel (4 mm thick). Reinforced and designed to withstand pressures up to -20" water column (5000pa).

Cartridge end caps.

The end cover is formed by stamping at one time, after electrophoretic coating technology, the protective paint is evenly arranged on the surface of the barrel cover to ensure the same thickness, strong and beautiful, no paint loss or bubbles will occur within 10 years, the triangular plastic installation handle of the end cover, humanized design, can be quickly rotated to install the cartridge cover

Cartridge.

The filter cartridge is an integral part of the TODC-L submerged dust collector, and the filter cartridge and the dust collector are cleverly combined together to greatly promote the functions of each. The combination of the cartridge and the dust collector greatly enhances their respective functions, gives the unit unparalleled performance and extends the life of the cartridge. This ingenious concept and design also This ingenious concept and design also optimizes the maintenance and servicing of the cartridges, giving the TODC-L a unique advantage in the industry. Due to the long service life of the cartridges and the Due to the long service life of the cartridges and their excellent dust collection and cleaning capacity, cartridge replacement is rarely required.

The dust collector uses a high efficiency cartridge as the filter element, which differs from conventional filter media in that it is coated with a Teflon film. 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, some of the dust particles will enter the filter material and block the filter element; when the blockage gradually worsens and effective dust cleaning is not possible, the air resistance of the filter element will rise and the air flow rate will drop. If there is no automatic dust cleaning, the filtration effect will drop rapidly, but the surface of the filter material used in this series of dust collectors is equipped with a layer of PTFE film, whose tiny screen pores 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, and the filtration efficiency for ≥0.1μm soot is ≥99.99%; and the service life is more than 2 times higher than the traditional filter media.

The cartridge adopts PTFE laminated filter material, which is a new type of fume and dust capturing filter element, and its filtration effect can be very impressive even in a particularly harsh environment. For non-bonded dusts, PTFE laminated filter elements achieve high filtration efficiency. The filter element maintains a constant filtration capacity even when the ambient temperature is below the dew point temperature. The high mechanical stability of the material ensures a long service life of the filter elements. The construction of the filters ensures that they are compatible with existing filtration systems. PTFE laminated filter media offer the advantages of membrane filtration and rigid body filtration. The small size and large filtration area of the robust rigid filter body allows high operating pressures and a very long service life.

Self-cleaning principle of the filter cartridge.

Cleaning of the dust collector filter material is achieved by means of a pulse blowing mechanism controlled by a differential pressure sensor: after the dust collector has been in operation for a certain period of time, fine soot is adsorbed in the filter material. After a certain period of operation, fine soot is adsorbed on the surface of the filter material, making the filter material less breathable. The two detection heads of the differential pressure sensor are installed on the raw air side and on the net air side. one on the raw gas side and one on the net gas side. When the differential pressure sensor detects the differential pressure exceeds a certain set value, the differential pressure signal is output and the pulse generator receives the signal. After the pulse generator receives the signal, the pulse blowing valve is activated sequentially, clean compressed air is ejected from the valve port, and the airflow is directed to the filter cartridge for blowing until the differential pressure is lower than another set value. The dust adsorbed on the surface of the filter material is removed under the action of airflow and falls into the dust collection hopper at the lower part of the chamber.

The pulse blowing requires 0.6 MPa of clean compressed air and must maintain a continuous and constant air supply during operation.
