Causes of damage of dust removal bag in plastic spraying equipment

In order to avoid dust pollution in the process of plastic spraying, the plastic spraying equipment is usually equipped with dust removal cloth bags. However, this kind of cloth bag is easily damaged in the process of use, which makes people always worried. So, what are the reasons for its damage?

The plastic spraying equipment is first affected by the dust medium. The selection of bag cloth of dust remover depends on the nature of the dust. The plastic spraying equipment should consider whether the dust contains acid, alkali or highly corrosive substances. Select suitable filter material according to the nature of the dust, so that the filter bag can absorb dust normally without affecting its service life.

Secondly, affected by the filtering wind speed, the high filtering wind speed of the bag filter is the main reason for the damage of the dust removal bag. In recent years, some units have blindly reduced the equipment cost and increased profits. When designing the bag filter, they have increased the filtering wind speed. In a short time, users have no obvious response, but the service life of the filter bag has been greatly shortened.

Thirdly, due to the impact of product quality, some small manufacturers use small sewing machines as processing equipment, and use low-quality thread as raw materials during processing, so the processing level is far behind. The filter bag will open, crack, drop bottom and other phenomena after being used for a short time. Although the size of the cloth bag is slightly smaller, it can also be used, but after absorbing the dust with large specific gravity, the bag will drop after a period of use.

The last point is the influence of the use temperature. The key to the filter bag is to correctly select the dust removal bag that is suitable for the corresponding dust temperature. If the temperature is too high, the selected dedusting cloth bag will exceed the normal use temperature. If the filter bag is light, its service life will be shortened, and if it is serious, it will burn out in a short time. Therefore, the inlet temperature of the precipitator must be measured and calculated when selecting the filter bag, and the corresponding dedusting bag must be selected.
