A brief introduction to the exhaust fan of the carding machine

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

Carding, opening and pick-up conveying and dust removal are in the steps of fans, centrifugal fans and two types of axial fans, among which centrifugal fans are used most, and axial fans are usually used as booster fans and exhaust fans for dust removal equipment. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. Grinder A spinning machine that turns fiber strands into rovings.

The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field.

The characteristic of the centrifugal fan of the carding machine is that the air can enter along the axial development of the Chinese fan, and flow along the radial direction in the impeller. It consists of a collecting roller, an hour wheel and a casing. The characteristic of the comb tooth fan is that the air enters along the axial direction of the fan and flows in the axial direction in the impeller. It consists of collector, fairing, impeller and casing.

During the opening and cleaning process of the bag filter, the filter capacity of the cloth roller must be considered. Filtration volume refers to the amount of dust-laden air filtered per unit area per hour, and the unit is 1/2 meter per hour. The larger the filter volume, the heavier the bag load.

The filter volume is small, the bag load is small, and the bag area is large, that is, the number of bags is large. Generally speaking, the filter capacity of the cloth bag is 60-100m/m2. If the amount of filtration is too small, the filtration resistance is small, but the filtration effect is poor, that is, the dust content of the exhaust air is large.
