purchase welding fume collector has the advantages of small size and high efficiency. With the development of new filter materials and the improvement of dust collector design, purchase welding fume collector has been used in dust removal engineering.
1, filter cylinder structure
The filter component of the purchase welding fume collector is the filter cylinder. The structure of the filter cylinder is divided into four parts: top cover, metal frame, pleated filter material and base.
The filter cylinder is the design length of the filter material folded into a pleat, end and end together into a cylinder; The inside and outside of the cylinder are supported by a metal frame, and the upper and lower parts are fixed by a top cover and a base. The top cover is provided with fixing bolts and washers. See figure for the performance and dimension of circular filter cylinder.
2, dust collector structure
The dust collector is composed of air inlet pipe, air exhaust pipe, box, ash hopper, dust cleaning device, filter cylinder and electronic control device.
The arrangement of the filter cylinder in the dust collector is very important, the filter cylinder can be arranged vertically on the box flower plate, can also be arranged tilted on the flower plate, fixed with bolts, and there is a rubber cushion; The lower part of the flower plate is divided into a filter chamber, and the upper part is divided into a clean gas chamber. In addition to bolting the cartridge, it is more convenient to use automatic locking devices and rubber compression devices, which are very convenient for installation and maintenance.
3. Working principle of purchase welding fume collector
After the dusty gas enters the dust hopper, due to the sudden expansion of air flow section, some of the coarse dust particles in the air flow settle down under the action of gravity and inertia force. After the fine particle size and small density dust particles enter the filter chamber, the dust is deposited on the surface of the filter material through the comprehensive effect of Brown diffusion and screening, and the purified gas enters the clean gas chamber and passes through the exhaust pipe
Machine discharge.
The resistance of purchase welding fume collector increases with the increase of the dust layer thickness on the filter material surface. When the resistance reaches a specified value, it is cleaned. At this time, the pulse controller controls the opening and closing of the electromagnetic pulse valve. When the pulse valve is opened, the compressed air in the air bag ejects a high speed and high pressure jet stream through the small hole on the jet pipe through the pulse valve, thus forming an induced defect flow equivalent to 1 ~ 2 times the volume of the jet stream, and enters the filter cylinder together, making the positive pressure in the filter cylinder and producing swelling and fretting. The dust deposited on the filter material falls off and falls into the ash hopper. The dust in the ash hopper is discharged continuously through the unloader.
