Liquid/solid separator for use in chemistry, pharmacy and agro-food industry has suction unit to remove accumulated powder from filter surface

摘要

A separator, comprising a container (2) to hold a liquid/solid mixture, equipped with a filter (4) in its base to separate and accumulate a powdered product (10) filtered from the mixture, incorporates a suction system to remove the powdered product from the surface of the filter. The system comprises an extraction circuit (12) with a first end that can be positioned close to the upper surface (5) of the filter, and a second end that discharges into a powder recuperation vessel. It also has a means for creating a depression in the circuit relative to the container. The first end of the extraction circuit is in the form of a tube (15) that can be moved lengthwise and rotated relative to the container wall, or retracted from it, with a sensor to switch off the system when the tube is withdrawn.
