I. Structure of LMF-ⅠLMF-Ⅱ pulsating back blowing flat bag filter:
1. Upper box: It includes the dust collector cover, the rotary cover removal device, the clean room, the bag changing hole, the observation hole and the air outlet.
2. Middle box: Including flower plate, filter bag, filter bag frame, filter bag guide, filter chamber tube, air inlet and entrance door.
3． Lower box: Including positioning support frame, ash bucket, star-shaped ash discharge valve and support.
4． Anti-blowing dust cleaning mechanism: It includes a spiral arm, a nozzle, a split-circle blowback mechanism, a circulating air pipe, a reverse blow tube, a reverse blower, and a spiral arm speed reduction mechanism.
LMF-Ⅰ type pulsating counter-blow flat bag dust collector, LMF-Ⅱ type pulsating counter-blow flat counter-flow blower arm are driven by a reducer placed on the top cover, the counter-air blower is installed on the floor, and is connected to the swing arm through a central tube The filter bag is arranged in a circle, and the rotary arm is provided with a split circle backflush device. According to user requirements, platforms, ladders, and their foundations and circulating air ducts can be designed and installed according to site specific conditions.
1. Filtration: The dust-containing airflow enters the upper space of the filter room from the tangential direction. Because the inlet is a volute-type large particle and condensed dust particles, the ash bucket will be rotated down the cylinder wall under the action of centrifugal force. Small particles of dust are scattered in the gap between the bags of the filter room and are blocked by the filter bag. They are adhered to the outer layer of the filter bag. Purified air passes through the filter wall and is collected and adhered to the clean room through the filter bag guide. . The whole process is rigorous, and the dust removal effect is increased.
2.: With the progress of filtration, the dust retention is gradually thickened and the resistance of the filter bag is gradually increased. When the upper limit of the resistance of the anti-blowing control is reached, the anti-blowing machine can be manually turned on as required, or the anti-blowing machine and the anti-blowing rotary arm transmission mechanism can be automatically started by the differential pressure transmitter to perform back blowing. Automatic control devices can also be provided by our company. The anti-blow air flow with sufficient momentum is blown into the filter bag guide port by the spiral arm nozzle, blocking the filter air flow and changing the pressure conditions in the bag, causing the filter bag to substantially shake and shake off the accumulated dust. The spiral arms blow back one by one. When the resistance of the filter bag drops to the lower limit, the anti-blowing mechanism is manually closed or automatically stopped. In order to save the power of the anti-blowing machine and reduce the amount of anti-blowing, three or four circles (ie, 144ZC—Ⅱ 20ZC—type) of bag dust collectors are equipped with separate circles The backflush mechanism enables backflushing only one filter bag at a time.
Third, the main advantages:
The shell is designed according to the volute type inlet of the cyclone dust collector, which can play the role of local cyclone and reduce the load on the filter bag. At the same time, it has the shape of a cylindrical vault, so that the force is uniform, and the explosion resistance is strong.
