Problems solved by technology

However, since the problem of food waste collection and treatment has just been raised, there is still a lack of mature food waste treatment equipment in the market. The activity is reduced or even dead, which will affect the biodegradation rate and degree of degradation. It is urgent to develop a composting treatment device for kitchen waste

Embodiment Construction

[0029] Hereinafter, the embodiments of the present invention will be described in detail in conjunction with the accompanying drawings and examples, so as to understand the technical content of the present invention more clearly.

[0030] Such as figure 1 As shown, in a specific embodiment of the present invention, a kitchen waste composting device sequentially includes: a top, a main body and a bottom, wherein,

[0031] The main body includes an outer cylinder 1 and an inner cylinder 2 coaxially arranged inside the outer cylinder 1. The outer cylinder 1 and the inner cylinder 2 are two stainless steel hollow cylinders of the same height. The bottoms of the outer cylinder 1 and the inner cylinder 2 are located on the same level ; The inner wall of the outer cylinder 1 and the outer wall of the inner cylinder 2 are each provided with a filler layer 6, the filler in the filler layer 6 is composed of calcium-based bentonite, activated carbon powder and calcium carbonate, and the ...

Abstract

The invention discloses a kitchen waste composting device, which comprises: a coaxial and equal-height stainless steel hollow outer cylinder and an inner cylinder. Wires are respectively arranged on the outer cylinder and the inner cylinder and a power supply is connected to form an electric field, so that microorganisms in the kitchen waste Accelerate the composting process under electrical stimulation; by setting filler layers on the inner wall of the outer cylinder and the outer wall of the inner cylinder, they can promote electrical conduction, continuously buffer salt and water absorption, and adjust pH during the composting process to ensure the activity of microorganisms; The structural design of the inner cylinder and the outer cylinder realizes the function of temperature regulation to control the temperature during the composting process, so that the microorganisms are always at the most active temperature, so that the composting process continues at an appropriate temperature and the composting efficiency is the highest. The device of the invention can process kitchen waste with zero power consumption and high efficiency and obtain compost.

Description

technical field [0001] The invention belongs to the field of fertilizer manufacture, and in particular relates to equipment for fertilizer manufacture made from household or municipal garbage. Background technique [0002] In domestic waste, kitchen waste accounts for up to 50% to 70%, and kitchen waste is the main pollution source of urban domestic waste. The source separation of kitchen waste can not only avoid the mutual pollution between the various components of the waste, but also greatly reduce the pressure of terminal treatment. Kitchen waste is rich in organic matter, oil, and nutrients (nitrogen, phosphorus, potassium, calcium, and various trace elements), and has high utilization value. The treatment method is mainly resource-oriented. Looking at the kitchen waste treatment models of various countries, most of the United States composts kitchen waste and yard waste on a household basis; Japan promotes the reduction of the total amount of food waste, recycling as ...
