Problems solved by technology
However, the existing fan blowback dust removal generally has the defects of insufficient dust removal strength, or the flexible connection between the fan and the air box, high resistance, low pressure resistance, and short life. The instant injection effect of blowing and cleaning, and, when blowing, there are too many off-line filter bags, which reduces the effective filtering area
These all lead to the early failure of the filter bag, which reduces the service life of the dust collector and cannot meet the needs of the market

The invention relates to a telescoping mechanism for an air duct, which includes a back-blowing fan blower, a fan blower pulse valve, a spherical rotary joint, and a metal telescoping pipe. The back-blowing fan blower is connected to the fan blower pulse valve which is then connected to the metal telescoping pipe through the spherical rotary joint.
Description
technical field [0001] The invention relates to a dust collector device, in particular to an air duct telescopic mechanism. Background technique [0002] There are generally two methods for the airflow cleaning of the existing bag filter: one is to use compressed air to blow the dust, and the other is to use the blower to blow back the dust. Compressed air blowback requires the user to have a compressed air source . For users who have no air source, the bag filter is generally used to blow back the fan to clean the dust. However, the existing fan blowback dust removal generally has the defects of insufficient dust removal strength, or the flexible connection between the fan and the air box, high resistance, low pressure resistance, and short life. The instant injection effect of blowing and cleaning, and, when blowing, there are too many off-line filter bags, which reduces the effective filtering area. These all lead to the early failure of the filter bag, which reduces t...
