Abstract (en)

[origin: US4293410A] The magnetic filter has a magnetic cylinder (2) pivotally mounted in a housing (1) and having an inclined stripper (14). The bottom of the cylinder (2) is surrounded by a casing (5), whereby a flow channel (6) for the medium to be filtered is created between the cylinder (2) and the casing (5). One portion (5b) of the casing (5) can be mobile so that the flow-channel profile section can be changed. Decreasing the channel profile section causes an increase in the flow resistance, resulting in a backwash, so that even in cases of small quantities the level and hence the inflow characteristic of the filter is approximately the same as that of the full-load quantity.
