Description

A bag filter for feed production

technical field

The utility model relates to the technical field of dust collectors, in particular to a bag dust collector for feed production.

Background technique

During the processing and production of feed, a lot of dust-containing gas will be generated. If these dust-containing gases are directly discharged, it will cause a lot of pollution, cause damage to the environment, and endanger human health. Therefore, it is necessary to remove the dust in it before it can be discharged into the atmosphere. For further treatment, the dust in the gas is generally removed by a pulse bag filter.

During the actual use of the bag filter, the dust-containing gas entering from the air inlet will preferentially enter the dust bag on the side of the air inlet, so the dust bag on the side of the air inlet has higher pressure, is more easily damaged, and has dust After the gas enters the dust box directly, the large particles and small particles in the gas are directly blown to the bag by the fan without being screened, which further increases the pressure on the bag, resulting in serious damage to the bag, short service life and increased maintenance costs.

After the dusty gas is transported to the dust box by the fan, the dust in the gas is filtered on the surface of the cloth bag, and the compressed air is introduced through the air pipe to expand the cloth bag, and the dust on the cloth bag can be cleaned. There is a nozzle on the top, but the nozzle diameter is small, which leads to the limited spray distance and strength of the nozzle. It is difficult to clean the dust collector at the end of the bag. With the accumulation of operating time, the dust collector will be blocked, which will affect the normal operation. use.
