Problems solved by technology

In addition, biological treatment generally requires the moisture content of materials to be 55-60%, while the existing food waste generally has a moisture content higher than this, which is not conducive to the later biological treatment effect

Embodiment Construction

[0024] The present invention will be described in further detail below with reference to the drawings and specific embodiments.

[0025] What the invention discloses is a sorting device for food waste, such as Figure 1 to Figure 5 Shown are the preferred embodiments of the present invention. The food waste pre-sorting device includes a sorting device 1 and a squeezing and conveying device 2, wherein:

[0026] The sorting device 1 mainly includes an inlet 11, an inner and outer double-layer screen consisting of an inner cylinder 12 and an outer cylinder 13, a separation motor 14, an oil-water output port 15, a coarse material output port 16 and a fine material output port 17. . The material inlet 11 is connected to the inner cylinder 12, and the bag cutting teeth 18 are provided at the material inlet 11 to cut the garbage bag containing garbage, so that the garbage in the garbage bag can be discharged. A magnetic separation device 19 for collecting metal (such as nails, etc.) ca...

Abstract

The invention discloses an early-stage sorting device for kitchen garbage. The early-stage sorting device comprises a sorting device and a wiping and conveying device, wherein the sorting device comprises a material inlet, an inner layer screening barrel, an outer layer screening barrel, a separation motor, an oil and water outlet, a coarse material outlet and a fine material outlet; the wiping and conveying device is provided with a conveying tube; an input end of the conveying tube is connected with a fine material outlet; an output end of the conveying tube is connected with a biologic treatment instrument; the conveying tube is tapered, and the diameter of the output end of the conveying tube is less than that of the input end; and a spiral rod driven by a motor to rotate is arranged in the conveying tube. The sorting device can effectively sort inorganic garage and sort oil and water at the same time, and the wiping and conveying device controls the moisture content of the materials entering the biologic treatment instrument, so that later-stage biologic treatment is facilitated.

Description

Technical field [0001] The invention belongs to a garbage disposal device, in particular to a preliminary sorting device for kitchen garbage. Background technique [0002] Food waste is the domestic waste formed by residents in the process of daily consumption. Its main components include rice and flour food residues, vegetables, animal and vegetable oils, meat bones and other organic matter. Due to food culture and gathering habits, food waste has become a unique phenomenon in China. The waste of Chinese dining tables is amazing, and huge amounts of food waste are generated every day. According to figures from the Beijing Municipal Development and Reform Commission, Beijing generates 1,200 tons of food waste every day. Statistics from the Institute of Solid Waste Pollution Control and Resource Reuse, Department of Environment, Tsinghua University, show that Chinese cities produce no less than 60 million tons of kitchen waste every year. For a long time in the past, China did ...
