Kitchen waste rotary screen

Abstract

The invention relates to the technical field of waste treatment, in particular to a kitchen waste rotary screen. The kitchen waste rotary screen comprises a base, a screen drum, a shell, a first drive device and a second drive device, wherein the screen drum comprises an inner drum body and an outer drum body; the outer drum body is installed on the base in the mode of rotating around the axis lead of the outer drum body; the drum wall of the outer drum body is provided with a screen structure; the inner drum body is installed on the base in the mode of rotating around the axis lead of the inner drum body; the axis lead of the inner drum body is parallel to the axis lead of the outer drum body; the inner drum body comprises an inner drum head portion, an inner drum tail portion and a spiral blade of a hollow spiral body structure; the spiral blade is provided with a material raising mechanism; the inner drum tail portion extends out of the outer drum body; the shell is installed on the base and comprises a feeding hopper, a receiving board and an impurity outlet hopper; the receiving board is provided with a discharging hopper; the first drive device is installed on the base and is in transmission connection with the inner drum body; and the second drive device is installed on the base and is in transmission connection with the outer drum body. The kitchen waste rotary screen is not prone to generating winding and hanging phenomena and the screening efficiency of kitchen waste is high.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a kitchen garbage drum sieve. Background technique [0002] With the acceleration of social development and urbanization and the improvement of people's living standards, Chinese cities are facing increasingly serious environmental problems, especially the problem of food waste pollution. A large amount of food waste without orderly management not only affects the living environment, but also endangers the physical and mental health of citizens, becoming one of the serious public hazards in today's society. [0003] my country has a large population and a large output of food waste. A large amount of food waste is both "waste" and "treasure". A large amount of waste oil is the most economically feasible raw material for biodiesel production, and a large amount of organic matter can be used to produce clean energy such as biogas. At the same time, due to the different p...

AI Technical Summary

Problems solved by technology

[0004] At present, the composition of food waste in our country is complex, and the whole is viscous. The existing food waste treatment usually adopts manual sorting or grid machine for simple treatment, which leads to the problem of easy entanglement and hanging of food waste, which in turn leads to the Garbage screening efficiency is low
