Inspection and treatment of "ash" in cloth bag dust collector

Inspection and treatment of "ash" in cloth bag dust collector

Bag filter outlet "take the ash" has two kinds, one is the continuous "take ash", that is due to dust bag bag seriously damaged, lashing solid off, or bag dust collector on hanging mouth is not tight, hanging mouth and flower plate, plate between the flower and flower plate connection is not tight caused by the leakage of dust. The other is the instant "ash", in this case, although the dust filter bag is damaged, but not very serious, when the bag dust collector is sprayed, the instant "ash" appears.

When we find the cause of dust removal in bag filter, we can tell which exhaust filter bag and dust leak is based on the number of digits corresponding to the electromagnetic pulse valve and the pulse control device when the outlet is "ash". On the top of the bag filter, we can use the flashlight to filter out the dust bag from the upper box observation hole. If we open the lid and open the lid, we will open the pulse control device again, and find out which venturi tube is from the injection process, that is the dust bag filter. Then, deal with the problems according to the problems.

When replacing the dust filter bag with the bag filter, the cause of the breakage should be checked and analyzed. The factors that affect the life of the filter bag include the properties of dust, the distribution of the air flow, the processing quality of the dust removal framework and so on. As a result of its frame welding is not strong, in the process of welding process, the dust bag should be pierced, welding, and welding slag grinding polishing dust removal of burr, or change the new skeleton dust. The skeleton of a filter bag is usually welded with a steel wire with a diameter of 4 millimeters. There are two commonly used welding methods, one is spot welding with spot welding machine, the other is to use oxygen acetylene welding. Using the former method, the production efficiency is high, the surface is smooth, and the burr is not easy to be produced, and the deformation is small. Using the latter method, the production efficiency is low, the surface is rough, and the deformation is easy. In addition, the plastic frame is also used, but the frame is not suitable for use at high temperature. In the blowing process, because each bag cleaning time, and the outer surface of a friction dust frame, so the dust bag use after a certain period of time, although not damaged, but the inner surface and the contact part of the existing framework of dust wear, then loaded when used according to the original department will wear marks to avoid dislocation. Continue to wear in place, which can prolong the service life of the filter bag dust removal.

When installing the bag filter, we should pay attention to cleaning up the dust on the perforated panel to prevent the dust from being perforated, so as to prevent the leakage between the interfaces and the perforated plates, and affect the purification efficiency. The hole of the blowing pipe should be aligned with the venturi tube center to ensure the injection effect. To the side door deduster, attention should be paid to the tightness of the upper and lower hanger, in order to prevent the drop off of the lower hoist and the screw thread.

Dust bag removing installation should pay attention not to bag type dust collector and metal edges to prevent collision, injury.
