Embodiment 1

[0020] A device for harmless treatment of kitchen waste, comprising a crushing device, a conveying device, a dehydration device, an external water treatment device, a drying device, a pressing device and a composting device.

[0021] The crushing device includes a cylindrical shell, a motor provided outside the cylindrical shell, a helical stirring blade set inside the cylindrical shell and a shaft for installing the stirring blade, the upper part of the cylindrical shell is provided with food waste Garbage inlet, the lower part is provided with an outlet for broken kitchen waste.

[0022] The dehydration device is connected to the outlet of the crushing device, and includes a cylindrical inner shell, a cylindrical outer shell, and a liquid material collection pipe arranged between the two shells. The rotation of the shell separates the liquid matter and the solid matter in the kitchen waste.

[0023] The inlet of the external water treatment device is connected with the outl...

Embodiment 2

[0029] The specific use process of the harmless treatment device for kitchen waste in Example 1 is to connect the source of kitchen waste through the entrance of the crushing device, and the kitchen waste enters the crushing device and then crushes, so that the solid matter in it forms fine particles and Macroscopically, it is separated from the liquid substance, and then transported to the dehydration device through the conveying device installed inside the outlet of the crushing device and the inlet of the dehydration device, and the liquid substance is separated from the solid substance through rotary dehydration, and the liquid substance enters the oil-water separation tank of the external water treatment device to add The oil-water separation additive performs oil-water separation, and then removes the upper greasy matter, and extracts the lower water-based matter into the reclaimed water filter, and forms reclaimed water after being filtered and adsorbed by the multi-layer...

Abstract

The invention relates to a harmless kitchen garbage treatment device and belongs to the environmental protection field of refuse reclamation. The harmless kitchen garbage treatment efficiency can be improved by improving a crushing device with a specific structure, a dehydration device, a drying device, an external water treatment device, a pressing device and a compost device.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to the field of garbage recovery and reuse treatment, and in particular relates to a device for harmless treatment of kitchen waste. Background technique [0002] At present, landfill is the most common way to recycle kitchen waste, but with the increasing amount of waste, the disadvantages of landfill gradually appear, and because it contains a lot of organic matter, it is very easy to rot and deteriorate, and it is easy to produce waste after landfill. Biogas is prone to safety problems. At present, there are also some harmless treatment methods for kitchen waste. The main method is to crush it first, then dry and press it to form dry and relatively small waste. There are also many ways to produce biogas through microorganisms. However, there is no relatively complete overall treatment system for kitchen waste. Contents of the invention [0003] The purpose of the pres...
