Abstract
Abstract In order to produce a magnetic separator for separating particles from a fluid, comprising a collection chamber through which the fluid is arranged to flow, and a device for producing a magnetic field by means of which the particles are retained in a collector region of the collection chamber during a collection phase, whereby only a very small amount of liquid is lost when the particles retained in the collector region of the collection chamber are removed from the collection chamber after the collection phase, it is proposed that the magnetic separator comprise a sluice chamber having a closable inlet opening through which the particles collected in the collection chamber are transferable into the sluice chamber, and also having a closable extraction opening through which the particles are removable from the sluice chamber.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
129 words
A magnetic separator for separating particles from a fluid, comprising a collection chamber through which the fluid is arranged to flow, a device for producing a magnetic field by means of which the particles are retained in a collector region of the collection chamber during a collection phase, a sluice chamber having a closable inlet opening through which the particles collected in the collection chamber are transferable into the sluice chamber, and also having a closable extraction opening through which the particles are removable from the sluice chamber, and a receptacle for an air-cushion, said receptacle communicating with the collector region of the collection chamber and containing an air-cushion that expands when the flow of fluid into the collection chamber is blocked at the end of the collection phase.
Claim 2
Dependent Claim
129 words
