Filter device for separating solid particles from a liquid or gaseous medium from for example the pharmaceutical industry or nuclear chemistry.

摘要

Apparatus for the separation of solid particles, which by its structural design can be operated with high reliability its filtering capacity during operation can be followed with attention in a simple way and it can be used equally for the separation from liquids and gaseous medium, mainly in the fields requiring increased operational safety, thus for instance in the field of the pharmaceutical industry, organic chemical industry and even in the field of the nuclear industry, etc. The apparatus for the separation of solid particles according to the invention is suitable mainly for meeting the demands requiring increased operational safety, and it is formed with a primary space for receiving solid particles and medium, in given case for carrier medium and with a secondary space for the collection of filtered medium separated from each other by a filter member. In essence the filter member has a first filter element and a second filter element, the first filter element is arranged to confine the primary space, the second filter element is arranged to confine the secondary space, the first filter element is arranged to confine the primary space, the second filter element is arranged to confine the secondary space, the first and second filter elements together with the primary space only through the adjoining first filter element and with the secondary space only through the adjoining second filter element form an intercommunicating intermediate space, and an internal pressure sensor is arranged in the intermediate space.
