12000m3/H 240m² Workshop Dust Collection System

Features

1. Fume collector is configured with one suction arm. The bottom has two directional and two rotary polyurethane

casters with brake device for easy moving and stationing. It is suitable for the purification of fume and dust

generated in all kinds of welding, grinding and other places as well as for collecting rare metal particles and

precious materials.

2. Suction arm can be rotated 360 °, and can flexibly and easily reach the position and angle of sucking by pulling

the handle of the hood and position by itself in the absence of external force. Depending on needs, 2m, 3m or

4m flexible suction arm are available. Suction hose uses high temperature-resistant, flame retardant and wear-

resistant composite materials, and will not crack after burning through by spark and has a longe usage life; the

arm diameter is 160mm.

3. Fume generated in working will be sucked into the purifier through the hood, first through the fire resistance net,

large particles and sparks produced in grinding is intercepted and separated; then enter fume directing layer,

i.e. deflector, to ramify the fume to avoid residual spark into the main filter cartridge directly; at last the fume

enter the third layer i.e. the main filter cartridge, for ultimate purification, and it’s filtration efficiency reach 99.9%.

As the filtering precision of the main filter cartridge reach the indoor emission standards, clean air after filtration

can be directly discharged indoor through the air vents in the bottom of the purifier.

4. Power phase sequence instructions, short-circuit protection for lack of phase, with shut down protection

measures when too high temperature.

The working principle of cartridge filter

Cartridge filter is mainly composed of cabinet , filter cartridge and injection system, etc. When the dust gas into the dust collector, the sudden enlargement and air distribution plate will make the air flow in the part of coarse dust particles in under the action of gravity and inertia settling in ash hopper, fine granularity and density of small dust particles in dust filtering chamber.

By brown diffusion and sieve filter such as comprehensive effect, it makes the dust deposition on the surface of the filter material. The gas into after purification Air chamber by the exhaust pipe into the net. The resistance of cartridge filter material surface increase of the dust layer thickness.

Resistance to take when a specified value. At this time will be filtered air truncation first, and then open and electromagnetic pulse valve, the compressed air filter cartridge, make the filter cartridge expansion deformation produces vibration, and the reverse flow brush and attached to the filter bag looks on the surface of the powder. Ash hopper is sitting, stripped fall through the discharge valve discharge.

Structure Composition

Mainly consists of three parts: cartridge filter, cabinet and ash removal mechanism.

(1) Filter cartridge composed of outer layer. inner layer and the middle layer. Inner layer and outer layer are covered metal mesh (or hard plastic net). The middle layer is the fold type filter material. Cartridge filter characteristics is the filter material, put a layer of sub-micron ultra-thin fiber stick attached to the general filter material, The fibers on the adhesion layer are very close together, its clearance 0.12 - 0.6um. Due to the intensive folding and greatly increase the filter area, It has large area outstanding characteristic of filter cartridge.

(2) the cabinet is the shell of the dust collector, including the gas tank and ash hopper.Gas tank mainly provide the required cleaning space. It conducive to the reasonable distribution of flow field. The ash hopper is filtered to collect material.

(3) Ash removal mechanism mainly includes the blowpipe, pulse valve, air bags, etc. When the dust of filter cartridge surface reaches a certain thickness, It will be dedusted. The dust air througth filter cartridge, and then discharged. When the filter resistance to the differential value or time setting, It will controlled by differential pressure gauge or gain control instrument between the corresponding electromagnetic valve. The pulse valve in the closed state, compressed air blowing the filter cartridge to pulse ash removal.
