Abstract

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.

Description

Technical field [0001] The invention relates to the technical field of kitchen waste treatment equipment, and in particular relates to a swill treatment device suitable for school canteens, restaurants, restaurants and other catering industries. Background technique [0002] With the development of high and new technology and the improvement of people's living standards, catering swill is a component of urban domestic waste. It has become a tricky resource due to its large output, wide sources, and mixed components. At present, the treatment of catering swill in many cities and regions in China is still at the initial or small-scale stage, mainly including the following: direct feeding, landfill treatment, post-treatment incineration, etc. These treatment methods have virus transmission and environmental pollution. Problems such as the inefficient use of swill waste. In fact, catering swill is just a misplaced resource. The oil-water content of catering swill is 40%, and in the...
