Problems solved by technology

A significantly more compact construction is required for this, but the size of the effective filter element area used in this case cannot be significantly reduced, because otherwise particulate contamination of the fluid to be filtered would quickly cause clogging and premature replacement of the new filter elements. The filter element replaces the old filter element, which adversely affects the performance of the filter equipment

Embodiment Construction

[0033] exist figure 1 and 2 shows a filter device 10 according to the invention, which has a filter element 12 . The filter element 12 is accommodated in a filter housing 14 which has fluid connections 16 , 18 for the raw liquid or filtrate. The fluid connections 16 , 18 are connected to one another via the filter element 12 in a fluid-conducting manner. The filter housing 14 includes a head part 20 and a pot-shaped receiving part 22 . In this case, the head piece 20 has fluid connections 16 , 18 for unfiltrate and filtrate. The unfiltrate is guided from the fluid connection 16 for the unfiltrate along a first fluid-conducting path 24 in the direction of the interior of the filter element 12 . In this case, the first fluid-conducting path 24 runs at right angles to the deflection 26 . During filter operation, the fluid then flows through the filter element 12 from the inside to the outside, with dirt, in particular particles, accumulating on the inner side 28 of the filte...

Abstract

The invention relates to a filter device (10) comprising a filter element (12) which is accommodated in a filter housing (14) with fluid connection points (16, 18) for the non-filtrate and filtrate and said element can be passed through in both directions for filtrating the non-filtrate or for back washing for cleaning particle contaminations (72), said filter device also comprises a pressure control device (36) which generates a post-suctioning effect in order to improve the cleaning of the particle contaminations (72) on the backwashing filter element (12). Said filter element is characterized in that said filter device (10) is designed as a one filter-element solution and that, in a predetermined exchange, said single filter element (12) for filtering can be used for backwashing or can be backwashed using the pressure control device (36). The invention also relates to a hydraulic system (64) and to a method for backwashing a filter element (12) of a filter device (10) of said type.

Description

technical field [0001] The invention relates to a filter device having a filter element accommodated in a filter housing having fluid connections for unfiltrate and filtrate, and the filter element For filtering the non-filtrate or for backwashing in order to remove particulate dirt, a flow through in both directions is possible, and the filter device has a pressure control device, by means of which a regeneration can be generated on the filter element to be backwashed. Suction effect for improved cleaning of particulate dirt. The invention also relates to a hydraulic system with such a filter device and a method for backflushing a filter element of such a filter device. Background technique [0002] Such filter devices are known in the prior art, for example from WO 2009 / 062644 A1. In such a filter device, a plurality of filter elements are arranged offset relative to one another on a partial circle, and a device is provided for backwashing a corresponding one of such fil...
