Embodiment Construction
[0047] In order to illustrate the structure of the present invention more clearly, the attached Figure 1-3 Describe in detail with specific embodiments.
[0048] A kind of dynamic multi-layer automatic turning biological aerobic fermentation device of the present embodiment, such as Figure 1-2 As shown, it is a vertical structure. The main body of the fermentation device 10 has four layers of fermentation chambers separated from top to bottom. Each layer of fermentation chambers has two conveyor plate chain fermentation beds 16, which are staggered in the direction of material advancement. Layer relay connection, that is, the end of the upper layer is located above the starting end of the lower layer, and each layer of fermentation bed is inclined downward in the direction of material movement. The design of the conveying plate chain type fermentation bed 16 at the bottom is slightly longer, and also has a discharging function concurrently. There is a feed hopper 1 at the ...

Abstract
A dynamic multilayer automatic turning type vertical biological aerobic fermentation apparatus is characterized in that the internal of the main body of the apparatus is sequentially divided into a plurality of fermentation chambers from top to bottom, at least two dynamic fermentation beds are arranged in every chamber, the dynamic fermentation beds are sequentially connected in a downward staggered relay manner along the material forwarding direction, every dynamic fermentation bed is a conveyor plate chain type fermentation bed, and is provided with a speed-regulating driving device, the running directions of plate chains of the adjacent layers are opposite to each other, the tail end outlet of the upper conveyor plate chain type fermentation bed and the starting end of the lower conveyor plate chain type fermentation bed are distributed at intervals up and down to convey a material in a circuitous manner, a feeding hopper is arranged at the top of the main body and above the starting end of the first fermentation bed, the tail end of the bottom fermentation bed is provided with a material outlet, every fermentation chamber is provided with an oxygen supply fan and a plurality of air inlets, and the air inlets are located below the conveyor plate chains. The apparatus realizes automatic staggered layer turning, automatic interlayer turning, loose pile layers, good porosity,good air permeability, sufficient aerobic fermentation and material layer non-hardening during the dynamic conveying of the material.
Description
technical field [0001] The invention relates to the technical field of organic solid waste treatment and disposal, in particular to a dynamic, multi-layer and automatic stack-turning vertical biological aerobic fermentation device for sludge aerobic fermentation. Background technique [0002] At present, my country's urban sewage treatment produces more than 40 million tons of dewatered sludge with a moisture content of 80% per year, and continues to grow at a rate of 10% per year. At present, aerobic fermentation, as the most commonly used and mature technical method for sludge treatment and disposal, is widely used in the technical field of sludge treatment and disposal. The research on aerobic composting in my country started earlier. According to the development process of time, it can be divided into bar stack fermentation system, forced ventilation static stack system, fermenter system or reactor system. [0003] The traditional strip-stack fermentation system is to s...
