A washing pipe is mounted on a washing guide provided on an outer side of an outer cylinder screen of the screw press and includes a washing pipe body and washing nozzles provided in the washing pipe body and configured to discharge washing liquid flowing from an inside of the washing pipe body toward the outer cylinder screen. A washing pipe swing supporter is configured to support the washing guide to allow the washing pipe to swing between a discharge position and a separation position. The discharge position is a position where the washing pipe is mounted on the washing guide and the washing liquid is discharged from the washing nozzles toward the outer cylinder screen. The separation position is a position where the washing nozzles are farther away from the outer cylinder screen than in a state where the washing pipe is positioned at the discharge position.

A dewatering machine includes a screen, a screw and at least one moisture content control wing. The screen has a hollow inside, has an inlet portion through which livestock manure is inputted at a first side and an outlet portion through which dehydrated livestock manure is outputted at a second side, and has a plurality of moisture exhaust holes penetrating from an inside of the screen to an outside of the screen. The screw includes a rotation axis and a main wing formed into a spiral shape along a longitudinal direction of the rotation axis. At least one moisture content control wing is disposed between the main wings adjacent to the outlet portion, and is formed into a spiral shape along the longitudinal direction of the rotation axis.

The present disclosure encompasses a machine for extracting, squeezing, compressing and compacting a mixture of municipal solid waste to provide both an organic-rich liquid and solid RDF pellets, separately. The machine comprises a stepless hydraulic power transmission module and a press and squeeze compression module. The body of the machine comprises a waste-inlet on one end, followed by a water separation zone, a wet organic substance pressing zone, a heat and steam pressing zone, and an RDF molding and pelletizing zone. The machine also comprises a press-and-squeeze shaft having a conical cylindrical shape with an ascending diameter including a shaft body and a helix screw. The helix screw with multi-spiral forward steps and multi-spiral backward steps, with the spiral steps (distance between and among them) becoming smaller toward the bigger end of the body.

Proposed is a food waste disposal apparatus for automatically discharging food waste by compressing (naturally dewatering), cutting, and drying food waste. More specifically, proposed is a food waste disposal apparatus having a corrugated part provided at an input hole so that same can be bent in all directions, and thus construction is facilitated, and having, at a predetermined distance away from a drying drum that generates high heat, an exhaust fan for discharging internal air of a drying and discharging part, so as to minimize breakdown of the exhaust fan caused by high heat, and enable vibration and noise of the exhaust fan to be prevented.

The present invention relates to a cleaning device comprising at least two corpus elements, the corpus element comprises two interconnected side surfaces, the two interconnected side surfaces comprise a cleaning part and a connecting part for connecting the at least two corpus elements, wherein the cleaning part comprises a curved structure extending from a first-side to a second-side of the cleaning part.

The present invention relates to a screw press comprising a press chamber comprising a screw and surrounded by a cage, wherein the screw comprising a shaft having a helical structure on the outside of the shaft, and wherein the cage is provided with at least two cage elements, wherein at least one cage element of the at least two cage elements comprises a pivotable connection allowing the at least one cage element to pivot, wherein a screw press is provided with a cage open assistant, assisting the at least one cage element to pivot.
