Vibrating screen dust collector

The vibrating screen dust collector is a pulse dust collector commonly used in various gravel screening equipment. It is mainly used for dust collection and purification during vibrating screen operations, and can effectively deal with pollution problems caused by vibrating screens during the vibration process. At present, vibrating screen dust collectors have been widely used in various industries such as mining, building materials, grain, chemical industry, casting, ceramics, etc., and are a relatively good bag dust collector with a wide range of applications.

The vibrating screen dust collector is a new and excellent bag type dust collector developed on the basis of conventional dust collectors. It not only combines the characteristics of chamber blowback and pulse cleaning, overcomes the shortcomings of insufficient intensity of ordinary chamber blowback and general pulse cleaning dust reattachment, but also extends the bag to fully utilize the powerful cleaning effect of compressed air. It is a vibrating screen dust collector with good dust removal efficiency, small footprint, stable operation, excellent performance, and easy maintenance.

The cleaning of vibrating screen dust collector is different from that of general spray bag dust collector. Pulse cleaning only sprays and cleans each row of bags in the same filter chamber (known as re line cleaning), while the other rows of filter bags are still filtered. The cleaning and filtering are carried out simultaneously in one room, and the dust under the cleaning is secondary flown, some of which will be collected by adjacent filter bags, which is not conducive to the filtration of gases with high dust concentration. The PPC type pneumatic pulse bag filter is carried out when the valve is closed in one room to stop filtering. The cleaned dust settles downward in the ash half without secondary flying, which is extremely beneficial for filtering gases with high dust concentration. Moreover, the bag in another room can be changed without stopping the machine.

During the operation of the vibrating screen, a large amount of dust is generated. When the vibrating screen dust collector starts working, the centrifugal fan of the bag filter is used to form a negative pressure zone at the dust overflow point, and the dust containing gas is sucked into the dust collector. Multiple bags are installed inside the dust collector. When the dust containing gas passes through the bags, the powder and dust are blocked and separated, and the purified gas is discharged through the fan. When the dust on the surface of the bag increases and the resistance value reaches the predetermined value, the pressure sensor sends an indication signal to the electric control box. The pulse spraying system controlled by pLc automatically sprays the bag, shaking off the dust attached to the bag and directly reaching the belt through the sealed ash discharge pipe. Always maintain good filtering performance of the bag without generating secondary dust.
