Provided is a compressed air jet device A composed of an discharge port member 1 provided on a pipe P for connecting to a compressed air supply source such that the opening thereof faces downwards, and a hole portion 14 provided in the connection 10 between the pipe P and the discharge port member 1 and allowing communication between the interior of the pipe P and the interior of the discharge port member 1, wherein the vertical cross-sectional shape of the peripheral wall 2 of the discharge port member is formed so that the interior side and/or the exterior side of the discharge port member are inclined to have a smaller wall thickness towards the free end of the opening 1a.

A sand-manure liquid separation plant including a tank for the processing of a mixture of sand and manure liquid. The tank including a top portion having a mixture inlet for filling the mixture to be processed into the tank and a bottom portion having a sand discharge for discharging sand settled in the tank. A maximum level (ML) of filling of the mixture is defined within the tank, wherein the mixture inlet is arranged at a position at a level above the maximum level (ML) of filling. The plant further includes a number of fluid outlet(s) connectable to a source of a fluid and arranged above the maximum level (ML) of filling. The fluid outlets being configured to provide a flow of the fluid directed towards the maximum level (ML), below the position of the mixture inlet.

An automated skimmer system includes a skimmer mouth comprising a conveyor ledge, a conveyor at least partially disposed under the conveyor ledge having a paddle wheel and a water-porous conveyor belt disposed about the paddle wheel, a conveyor debris collector disposed lower than the conveyor at a discharge end of the conveyor having a vacuum connection port, and a vacuum fluidly connected to the vacuum connection port. Water entering the skimmer mouth falls off the conveyor ledge, through the conveyor belt, onto the paddle wheel causing the paddle wheel to rotate and the conveyor belt to direct debris toward the conveyor debris collector for automated removal. The vacuum may be activated according to a predetermined interval, a predetermined schedule, or based on level sensor data to ensure that the automated skimmer system does not become clogged, without requiring manual intervention.
