Kitchen garbage composting device

Abstract

The invention discloses a kitchen garbage composting device. The device comprises a stainless steel hollow outer cylinder and an inner cylinder which are coaxial and have the equal height, and the outer cylinder and the inner cylinder are respectively provided with lead wires and are connected with a power supply to form an electric field in order to make microorganisms in the kitchen garbage accelerate the composting process under electrical stimulation; the inner wall of the outer cylinder and the outer wall of the inner cylinder are provided with packing layers to promote electricity conduction, continuously buffer salts and absorb water and adjust the pH value in the composting process, so the activity of the microorganisms is ensured; and the structures in the inner cylinder and the outer cylinder are designed to achieve temperature regulation in order to control the temperature in the composting process, so that the microorganisms are always at the most active temperature, the composting process is continuously carried out at an appropriate temperature, and the composting efficiency is the highest. The device of the invention can achieve the purposes of processing the kitchengarbage with zero power consumption and high efficiency and obtaining a compost.

Description

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

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
