Title:
NOVEL REGENERABLE FILTER ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/198890
Kind Code:
A1
Abstract:
The present invention provides a novel regenerable filter element, comprising: an inner frame, a filter bag sleeved outside the inner frame, a filter bag sealing ring connected to the filter bag, a fixed ring sleeved outside the filter bag sealing ring, a press cover, and a plurality of O-shaped rings. The O-shaped rings are jointly squeezed by the filter bag sealing ring and the fixed ring. The press cover and the fixed ring are connected so that the inner frame and the fixed ring jointly squeeze the filter bag sealing ring. The novel regenerable filter element provided by the present invention is flexible and convenient to disassemble and assemble, and further has a blowback effect. A filter cake outside the filter bag can be removed, so that the filter bag can be recycled. In addition, the O-shaped rings are arranged between the filter bag sealing ring and the fixed ring, thereby realizing a good sealing effect and preventing outward water seepage from a connecting gap.
