Filter device

摘要

The present invention relates to a filtering device, facilitating the filtration of media to be cleaned, and also the cleaning of the filter material or filter elements in a filtering device. Said filtering device comprises at least one filter element arranged in a housing, with at least one filter material and at least one rebound element. The invention further relates to a cleaning device, comprising at least one nozzle, which is arranged perpendicularly and/or angularly in relation to the filter element for removing a filter cake on the filter material, wherein the cleaning medium at least partially penetrates the filter material during cleaning. The rebound element deflects the cleaning medium at least partially for renewed penetration through the filter material, while at least partially removing the filter cake at the same time.

主权项

1. A filtering device comprising:
a housing defining a filtration flowpath, the housing having at least one inlet and at least one outlet through which a filtrate flows, at least one cylindrical filter element arranged within the housing, the at least one cylindrical filter element having at least one filter material and at least one rebound element, the at least one rebound element having a first flange extending from a head region and a second flange extending from a foot region, the at least one rebound element having a structured surface with at least two recesses mutually parallel in the longitudinal direction of the rebound element, the at least two recesses are formed extending between the first flange and the second flange, the at least one rebound element having at least one opening through which the filtrate flows into an interior of the at least one rebound element, the at least one opening is arranged on the structured surface of the at least one rebound element adjacent one of the head region and the foot region in an area of extension of at least one of the at least two recesses, where the at least one rebound element is at least partially covered with the at least one filter material, and a cleaning device, having at least one nozzle that corresponds with each individual at least one filter element accommodated in the housing, the at least one nozzle which can be directed, for the removal of a filter cake on the at least one filter material by means of a cleaning medium, perpendicularly and/or angularly in relation to the filter element to which the at least one nozzle corresponds, where the cleaning medium at least partially penetrates the filter material, and the rebound element deflects the cleaning medium at least partially for a renewed passage through the filter material with at least partial removal of the filter cake at the same time, and where the filter element is designed to be moveable.
