Description

A kind of ash discharge valve for sintered plate dust collector

technical field

The utility model relates to the technical field of ash discharge valves, in particular to an ash discharge valve for a sintered plate dust collector.

Background technique

The sintered plate dust collector, also known as the sintered plate filter and the plastic sintered plate dust collector, is a dust collector with gas filtration as its working principle. The filter element used is a sintered plate filter element. The deflector at the bottom enters the dust chamber of the middle box, and the gas purified by the sintered plate is discharged through the fan. As the dust trapped on the surface coating of the sintered plate increases, the dust removal control system in the working mode of timing or constant differential pressure will automatically open the quick-opening pulse valve, and the dust on the surface of the sintered plate will be effectively removed by compressed air. The sprayed dust falls into the ash hopper under the action of gravity and is discharged.

The ash discharge valve on the sintered plate dust collector is used to be installed at the discharge port of the dust removal and ash discharge valve working under negative pressure. The upper part receives the material discharged from the unloader, and the rotating impeller plays the role of conveying the material and is responsible for the It acts as a seal to prevent air from being sucked in from the discharge port during the pneumatic conveying process, and ensures the normal discharge of the discharger.
