Garbage fermenting system

Abstract

The invention discloses a garbage fermenting system. The system comprises a garbage automatic dehydrating facility capable of performing spinning drying and air drying on garbage. The facility comprises a cylinder, in which multiple plugholes are arranged; a radial blowing pipe, which is arranged in the cylinder; a wind supplying device, which is connected to one end of the radial blowing pipe; an axial blowing pipe, which is connected to the wind supplying device and points at the front end of the cylinder; a driving device for driving the cylinder to rotate; an electric door, which is arranged on the outlet of the cylinder to close / open the cylinder; and a controller, which is individually connected to the wind supplying device, the driving device, and the electric door. The grinding device of an garbage fermentation facility in the garbage fermenting system comprises a cylinder; a feed hopper, which is arranged on the upper part of one end of the cylinder and is communicated with the cylinder; an auger, which is arranged in the cylinder; a driving motor, which is fixed on the cylinder, wherein the rotation shaft of the driving motor is connected to the auger; and a plurality of grinding teeth, which are arranged on the internal wall of the cylinder in the axial direction. The provided system can carry out spinning drying and air drying on garbage at the same time and achieve the automation of garbage dehydration.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a garbage fermentation treatment system. Background technique [0002] At present, my country's urban domestic waste is increasing at a rate of 10% every year, and the urban waste that implements simple treatment only accounts for 2.3% of the total. 8 billion yuan. The number of cities across the country has grown to 660, and 200 of them have been surrounded by garbage. Based on an urban population of 260 million and each person producing 440 kg of waste per year, the amount of waste generated is 114 million tons, which can cover a city with a population of 1 million by 1 meter. And it is still increasing at a rate of 8-10% every year. China has become the country with the heaviest burden of garbage in the world, and the harmless, volume reduction and recycling of urban garbage is imminent. [0003] At present, domestic garbage collection methods are all mixed...

AI Technical Summary

Problems solved by technology

[0004] 1. Mixed and received ingredients are complicated, and the content of bags is high;

[0005] 2. High water content, the average water content is 50%, and the limit water content is as high as 70%;

[0006] 3. The content of kitchen waste and muck is high, and it is difficult to separate and dehydrate;

[0007] 4. The content of perishable substances is high, and improper handling will cause serious secondary pollution

[0011] 1. The operating environment is harsh and the secondary pollution is serious: the method of draining water and fermentation and evaporation is used to remove water, which has a long cycle, a large amount of malodorous gas emissions, a large amount of landfill leachate, and high COD and BOD content in the leachate. Treatment costs are high ;

[0012] 2. Affected by the change of garbage moisture, the performance of fermentation products is extremely unstable
