A kind of catering swill treatment device

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, in particular to a swill treatment device suitable for school canteens, restaurants, restaurants and other catering industries. Background technique [0002] With the development of high technology and the improvement of people's living standards, catering swill is a part of municipal solid waste. It has become a difficult resource due to its large output, wide source, and miscellaneous components. At present, the treatment of catering swill in many cities and regions in China is still in the initial stage or small-scale stage, mainly including the following: direct feeding, landfill treatment, incineration after treatment, etc. These treatment methods have virus transmission, environmental pollution, The swill waste can not be effectively used and other problems. In fact, restaurant swill is just a misplaced resource. The oil-water content in catering swill is 40%, an...

AI Technical Summary

Problems solved by technology

However, the existing swill treatment device has a low degree of automation, swill treatment is greatly affected by the ambient temperature, and there are defects such as low solid-liquid separation efficiency, low oil-water separation purity, swill treatment equipment is easily blocked by treatment residues, and cleaning is inconvenient.
