Abstract
Abstract An apparatus for separating solid particles from a liquid carrying the solid particles. The liquid carrying the solid particles enters a cylindrical chamber having an upper portion with an air evacuation opening. The liquid flows down the sides of the chamber onto a funnel-shaped member. An exchangeable collecting vessel is positioned below the funnel-shaped member and retains and collects solid particles which precipitate out from the liquid. The liquid flows through an opening to a drainage container. The exchangeable collecting vessel has a self-closing resilient membrane covering its opening. The resilient membrane is pierced by a wedge-shaped projection at the drain opening when the collecting vessel is in position. When the collecting vessel is removed, the opening is closed by the resilient membrane to form a hygienic seal.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
124 words
A device for separating solid particles from a fluid carrying the particles comprising a substantially cylindrical separation chamber having an upper portion including a feed opening for receiving the fluid carrying the particles, an air evacuation opening for providing a vacuum to said separation chamber, and a lower portion having a drainage opening through which the fluid may be drained; a funnel-shaped member secured to the separation chamber disposed between the feed opening and the drainage opening; an exchangeable collecting vessel for collecting and retaining the particles, said collecting vessel having an inlet opening located below the funnel-shaped member and an outlet having a self-closing resilient membrane thereacross; and means for piercing said resilient membrane and for sealably engaging it with the drainage opening.
Claim 2
Independent Claim
124 words
A device for separating solid particles from a fluid carrying the particles comprising a substantially cylindrical separation chamber having an upper portion including a feed opening for receiving the fluid carrying the particles, an air evacuation opening for providing a vacuum to said separation chamber, and a lower portion having a drainage opening through which the fluid may be drained; a funnel-shaped member secured to the separation chamber disposed between the feed opening and the drainage opening; an exchangeable collecting vessel for collecting and retaining the particles, said collecting vessel having an inlet opening located below the funnel-shaped member and an outlet having a self-closing resilient membrane thereacross; and means for piercing said resilient membrane and for sealably engaging it with the drainage opening.
Claim 3
Dependent Claim
45 words
The device of claim 1 wherein said means for piercing said resilient membrane and for sealably engaging it with the drainage opening includes a bushing having a pointed wedge-shaped projection, which bushing and resilient membrane form a seal between the outlet and the drainage opening.
Claim 4
Dependent Claim
43 words
The device of claim 1 further including a drainage container having a lower portion which is connected through a check valve to a drainage main and an upper portion connected through a pressure balancing duct to the separation chamber below the funnel-shaped member.
Claim 5
Dependent Claim
47 words
The device of claim 1, wherein the feed opening of the chamber is connected to a feed pipe supplying the fluid with solid particles tangentially along an inner wall of the chamber where the fluid is guided downwardly by a helical guide bar attached on the chamber.
