Abstract
The invention relates to a device (1) for use in collection and removal of slurry or similar from a sty, a sty comprising such a device and to a method of installing a device at a sty, such as a pig sty, wherein the device comprises an one-piece body (2) having one or more funnels (3) wherein each funnel comprises at least one upper opening (3a) having an upper horizontal area enclosed by an upper edge (3a′) and a lower opening (3b) having a lower horizontal area enclosed by a lower edge (3b′), wherein the upper horizontal area is larger than the lower horizontal area, and the inside (3′) of the funnel is thus extending from the upper opening to the lower opening of the funnel, an encapsulation (4) enclosing the funnel from the lower edge of the funnel to the upper edge of the funnel, such that a ventilation space (5) is defined within the one-piece body between the encapsulation and the funnel.
