Description

Combined magnetic and sieve filter for liquids with previously known combined magnetic and sieve filters, either the magnetic insert was in a special Part of the filter housing housed, or the magnetic bodies were placed in the sieve filter insert built-in. The first version requires larger dimensions for the filter housing and complicated channel guides, while the latter type requires that for the purpose of one Cleaning of the magnetic body and the whole of the much larger screen filter insert must be expanded.

In the invention described below, these drawbacks become apparent thereby avoided that formed at the lower end of the known type of sieve plates Siebfiltereinsatzes a plate with attached stub shaft-like magnetic bodies is arranged with a center screw on a middle on the sieve insert cover arranged, special, small cover is attached, furthermore this disc the filter sieve plate is tightly guided in the center hole of the lower clamping ring and so separates the central space of the sieve filter insert downwards, while the Magnetic body into the middle flow opening leading to the pre-filter space protrude.

To clean the magnet body from the accumulated iron particles after loosening the screws of the small cover this together with the attached Disc with the magnetic bodies through the central space of the sieve filter insert to be expanded upwards. The invention relates only to filters with external Acting on the sieve plate and extending radially from the outside to the center of the same Flow of the liquid to be cleaned.

The drawing shows such a filter, for example with disc-shaped, seven plates acted upon on both sides in section.

The filter housing a is completed by the filter cover b, the by means of the disk c attached to it, the filter space into an inlet space E and an exit space = 4 separates. Under the entry room E there is a with the Inlet nozzle connected pre-filter chamber V, which through a central opening into the the magnetic body 1 also protrude somewhat, with which the inlet space E is connected.

The sieve plates d are arranged in layers on the disk c and held together by the clamping rings by means of the screws f. On the filter cover b the small cover g is fastened with the screws in its center. He wears by means of the screw i at the lower end of the washer, which is tightly guided in the ring e k and then the magnetic body 1, which are arranged so that the whole at m the amount of liquid entering the magnet body 1 must be struck through. After passing the magnetic body 1, the liquid flows through the sieve plate d from the outside to the inside and flows via the central space to the outlet space A and through the outlet nozzle n cleaned off.

The diameter of the magnet system is slightly smaller than the inner one Diameter of the sieve body or the sieve disks held so that when protruding of the magnet insert a stripping of dirt particles is avoided as far as possible.

Claims (1)

PATENT CLAIM: Combined magnetic and sieve filter for liquids with filter sieve plates of known design, which are arranged in such a way that the to be cleaned Liquid after passing through the magnetic filter part radially off the filter sieve plate flows through the outside to the center of the sieve filter insert, characterized in that that at the lower end of the screen filter insert in the middle one in the lower clamping ring the sieve filter body tightly guided and with down into the central opening in the bottom the entry space protruding stub shaft-like magnetic body provided disc is arranged, which is arranged on a center on the actual filter cover smaller lid is attached, so that when you remove the latter also at the same time the Disc with the magnetic bodies through the central space of the sieve filter insert can be expanded above.
