The process of corn flour milling machinery is still relatively complex, with many processes, which must be combined with a variety of equipment to form a flour production line. Among them, the bag filter as part of the role of dust removal. Today we will take a look at the common types of bag filters for corn flour milling machinery.
1, corn flour processing machinery can be divided into round bag and flat bag type dust collector according to the shape of the filter bag. The filter cloth of the round bag type dust collector is a round bag with a diameter of less than 300 mm, which is easy to remove dust, easy to install, and very uniform expansion. The shape of the interface of the flat bag filter bag is square or trapezoidal, with a large filtration area, a large expansion of the long side, and a large gap required for the arrangement.
2, according to the direction of filtration of corn flour processing machinery can be divided into internal and external filter dust collector. In the internal filter cloth dust collector, the dusty airflow passes through the filter bag from the inside to the outside, and the dust is retained on the inner surface of the filter bag. As the air passing through the filter bag is to purify the air, the internal filter cloth dust collector can be without shell and the filter bag can be without holder, which is suitable for manual knocking and cleaning, and convenient for bag replacement and maintenance. External filter cloth filter: dusty airflow from the outside to the inside through the filter bag, dust is trapped in the outer surface of the filter bag.
3, according to the corn flour processing machinery cleaning method is different, all kinds of filter cloth dust collector dust removal mechanism and the same filter cloth filtration effect is the same, the difference lies in the different cleaning methods. The general mechanical cleaning method of flour is simple to install, high strength, uneven cleaning, easy to wear the filter cloth, poor cleaning effect. Modern bag filters have been rarely used. Air flow cleaning method is widely used because of its uniform cleaning, good cleaning effect, high filtering air velocity, easy automation control and other characteristics.
