Title: Automatic self cleaning air filter - e.g. for cement dust extraction
Inventor: HAGE STANISLAS
IPC: B01D46/04
Filed: 1975-07-15
Abstract: The parent patent described a filter in which the chamber downstream of the filter elements was divided into compartments by partition walls. For cleaning the elements corresp. to a particular compartment, a flap was closed to seal the outlet from the compartment and a valve was simultaneously opened to allow air at a higher press. than that in the filter to blow back through the element. According to the present patent the chamber upstream of the elements is divided into compartments by partitions in the form of extensions from those in the downstream chamber. Dust shaken off one group of elements is prevented from being carried over directly onto other elements. The filter is fitted with a more sensitive press. difference gauge enabling operator to establish time for cleaning. Partition walls can be used to assist cleaning.
