Integrated aerobic fermentation system with double-layer structure

Abstract

The invention relates to an integrated aerobic fermentation system with a double-layer structure. The integrated aerobic fermentation system with the double-layer structure comprises a primary fermentation chamber and a secondary fermentation chamber which are distributed in upper and lower double layers; an empty vehicle lifting chamber is arranged on one side of the primary fermentation chamber and the secondary fermentation chamber, and an empty vehicle landing chamber is arranged on the other side of the primary fermentation chamber and the secondary fermentation chamber; driving devices of fermented material moving vehicles are arranged on one side of the upper layer of the empty vehicle lifting chamber and one side of the lower layer of the empty vehicle landing chamber correspondingly; a plurality of fermented material moving vehicle strings, which are connected end to end and form an integrated flat plate, are arranged on the middle part of each of the primary fermentation chamber and the secondary fermentation chamber; a material lifting machine for conveying to-be-fermented materials to the starting end of the fermented material moving vehicle strings as well as screw conveying machines for outputting the fermented materials arranged on the other side of the empty vehicle lifting chamber; the screw conveying machines are arranged on one side of an upper overturning machine and one side of a lower overturning machine correspondingly; the upper overturning machine is arranged on the upper part of the primary fermentation chamber; the lower overturning machine is arranged on the upper part of the secondary fermentation chamber; and a material conveying channel is arranged between the upper overturning machine and the lower overturning machine.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to an integrated aerobic fermentation system with a double-layer structure. Background technique [0002] At present, two kinds of processes are usually used in the feeding and discharging links of trough-type aerobic fermentation compost, one is a loader plus a dump truck, and the other is a belt conveyor plus a compost turner. The method of loading and unloading materials with a loader and a dump truck is a fully manual operation, which is labor-intensive and inefficient. Vehicles frequently entering and leaving the fermentation tank will compact the fermentation materials and block the aeration plate at the bottom, resulting in incomplete and uneven fermentation, prolonging the fermentation cycle, and at the same time, fuel vehicles will cause secondary pollution. The method of feeding and discharging materials with a belt conveyor and a compost turner is semi-mechanize...

AI Technical Summary

Problems solved by technology

The above method cannot realize automatic feeding and discharging of fermented materials, and the production efficiency is low and the cost is high

[0005] In addition, the existing sludge fermentation facilities all adopt a flat single-layer fermentation tank arrangement structure, which has the problems of large floor area, relatively complex structure, low degree of automation, and low utilization rate of fermentation tanks.
