Closed double-layer barrel aerobic fermentation cylinder

Abstract

The invention discloses a closed double-layer barrel aerobic fermentation cylinder, comprising a support device, a barrel, a powder driving device, a ventilation device and a feeding and discharging system, wherein the barrel and the power driving device are respectively arranged on the support device; the barrel comprises a feeding fixed end cover, a middle rotating barrel and a discharging fixed end cover; the middle rotating barrel comprises an inner barrel and an outer barrel which are arranged along the same axial direction and are fixedly connected with each other by a connecting support plate; a material retaining seal structure is arranged between one end of the inner barrel of the middle rotating barrel and the feeding fixed end cover, and another material retaining seal structure is positioned between the other end of the inner barrel of the middle rotating barrel and the discharging fixed end cover; the feeding fixed end cover and the discharging fixed end cover are respectively connected with the middle rotating barrel by an end cover fixing device; each end cover fixing device comprises a rotation fixing structure and a rotation support structure. The closed double-layer barrel aerobic fermentation cylinder is simple in structure, high in working efficiency and degree of automation, reliable in operation and good in treatment effect, is free from odor spillover in the treatment process, and is capable of realizing harmless and resource utilization of kitchen wastes.

Description

technical field [0001] The invention belongs to the technical field of kitchen waste treatment and utilization, and in particular relates to an aerobic fermentation drum with a closed double-layer cylinder. Background technique [0002] Food waste is the most important type of food waste, including food processing leftovers (kitchen waste) and food residues (swill) produced by families, schools, canteens and catering industries. Its composition is complex, mainly a mixture of oil, water, fruit peels, vegetables, rice noodles, fish, meat, bones, waste tableware, plastics, paper towels, etc. From the chemical composition, there are starch, cellulose, protein, lipids and inorganic salts. The amount of food waste in my country is very large, and it is showing a rapid upward trend. [0003] Food waste has obvious hazards and resource duality, and its characteristics can be summarized as follows: (1) High moisture content, up to 80%-95%. ⑵ High salt content, some areas contain ...

AI Technical Summary

Problems solved by technology

[0006] (1) Pollution of the environment and impact on city appearance

Because food waste contains high organic matter and moisture, it is susceptible to the action of microorganisms, resulting in decay and deterioration; and the longer the waste is placed, the more serious the deterioration will be

Especially in summer, when the temperature is higher, the decay and deterioration will be faster. At this time, a large amount of percolation water and malodorous gas are likely to be produced, breeding mosquitoes, and causing adverse effects on environmental sanitation.

[0007] (2) Harmful to human health

[0009] (4) The infiltrate produced when food waste is piled up enters the sewage treatment system, which will increase the content of organic matter, thereby increasing the burden on the sewage treatment plant and increasing operating costs

The aerobic fermentation equipment is the key to determine the treatment of nutrient soil. The existing aerobic fermentation equipment has defects such as complex structure, small processing capacity, long fermentation cycle, uneven fermentation degree, poor treatment effect, easy failure, and low degree of automation. , needs to be further improved
