Problems solved by technology

[0005] The solutions described above are experientially bulky and are often complex and therefore expensive to install on-site from an installation point of view
Due to the different installation positions of the filter device and the associated bypass filter, even if they are arranged next to each other, different thermal operating conditions occur, which can adversely affect the fluid handling, especially in the area of ​​fluid filtration

Embodiment Construction

[0031] figure 1 Shows a general view of a filter device according to the invention with a filter housing 10 having three filter chambers (a first filter chamber 12, a second filter chamber 14 and a third filter chamber Filter chamber 32 (see figure 2 )), spindle housing 24, housing body 16 and drive unit 22. Provided on the spindle housing 24 is a fluid inlet indicated by 28 for supplying the fluid to be cleaned, and an outlet indicated by 30 for discharging the cleaned fluid. One filter element 34 is installed in each filter chamber 12, 14, 32 (see image 3 ), 60 (see Figure 4 ). The central component of the filter device is the conversion device 18, which is received by the main shaft housing 24 and figure 1 Only the operating device in the form of a hand lever 26 is visible in the conversion device. Furthermore, a backflushing device 20 is provided on the filter device, which is accommodated in the housing body 16 and figure 1 The drive unit 22 arranged above the h...

Abstract

Filter device for cleaning a fluid flow of particulate contamination, having a plurality of filter elements (34, 60) received in a filter chamber as part of a common filter housing (10) (12, 14, 32) and surrounds the backwash device (20), which has a piston accumulator (56) in order to receive the backwash volume, in its accumulator housing (64) the piston (57) Guided longitudinally, the piston is controlled by a pressure medium to transfer the backflush quantity stored in the accumulator housing (64) via the backflush device (20) to at least one unit to be backwashed for its cleaning. The filter element (60), the backwashing device also leads the backwash amount from the filter equipment, it is characterized in that a certain filter element selected from the plurality of filter elements (34, 60) is used as a bypass filter element ( 34) After operating the switching device (18), only particle cleaning takes place, while the other filter elements (60) are excluded from this cleaning.

Description

technical field [0001] The present invention relates to a filter device for cleaning a fluid stream of particulate contamination. Background technique [0002] Such a filter device is known, for example, from WO 2012 / 150011 A1. The known filter device comprises a pressure control device for assisting the backwashing of the individual filter elements, the pressure control device having a hydraulic accumulator, a fluid chamber of which can be filled with a certain amount during the filter process The cleaned fluid can be connected to the cleaning side of the filter element to be cleaned via a backflushing line for the backflushing process. The other fluid chamber of the hydraulic accumulator can be supplied with gas pressure for the backflushing process, so that the resulting movement of the separating element of the hydraulic accumulator fills the cleaned fluid for the backflushing process of the filter element The volume is at least partially discharged from the one fluid ...
