The invention discloses a restaurant swill
processing device. The restaurant swill
processing device is formed by combining three independent parts which are a first-level
solid-liquid separation device, a second-level
slag removing device and a third-level oil-liquid separation device, wherein the first-level
solid-liquid separation device is self-provided with a temperature detection and constant temperature
heating system, the second-level
slag removing device is provided with a
differential centrifugation mechanism, and the third-level oil-liquid separation device is provided with a biochemical filter screen and an automatic oil liquid extracting mechanism; the first-level device and the second-level device are connected by a connecting
pipe, and the second-level device and the third-level device are connected by an
axial flow pump. According to the restaurant swill
processing device disclosed by the invention,
dehydration is carried out on swill through gradually varied screw blades so as to obtain
solid residues, which have different water contents, and a separating medium, wherein the solid residues can be processed into feed or
fertilizer after being collected, afterwards, the separating medium enters the second-level
slag removing device, secondary
filtration is carried out on the separating medium by utilizing
centrifugal force, finally, the third-level oil-liquid separation device is used for processing, the obtained liquid meets the requirement of
environmental protection, the degree of
automation is high, and the continuous and large-batch swill processing can be realized.
