Common tank type organic manure composter and fermentation equipment for sludge harmless treatment

The high temperature aerobic fermentation process can be divided into three stages: rapid heating stage, high temperature stage and cooling stage. The material enters the fermentation chamber and decomposes rapidly within 1-2 days. The released heat causes the material temperature to rise rapidly, generally 50-65 . Up to 80 . Through the air supply system, oxygen is evenly supplied to the fermentation chamber to meet the oxygen demand of the fermentation process, so that the materials can be fully fermented and decomposed, and the high temperature stage can be maintained for 5-7 days. When the decomposition rate decreases slowly, the temperature decreases gradually. The whole fermentation process lasted 9 ~ 10 days. Temperature rise and aeration speed up the evaporation of material moisture, thus reducing the volume of material and achieving the reduction and stabilization of material. When the temperature of fermentation chamber is kept above 50 for 5-7 days, it can kill insect eggs, pathogenic bacteria and weed seeds. Meet the national treatment requirements and achieve the purpose of sludge harmless treatment.

Tank type organic fertilizer fermentation equipment. The equipment required for tank fermentation is the tank type fermentation upender, which has the advantages of large processing capacity, small land occupation, simple operation and unmanned driving. However, due to the need to build fermentation tanks, the fermentation field is fixed, which has certain limitations, and the air permeability is not as good as the bar stack type. At present, on the basis of the function of turning and throwing, some of the tank type fermentation organic manure turning machines are designed with oxygen adding devices, which can increase the permeability; Some of them have added the function of breaking and stirring, which is suitable for fecal type, dregs and fermented products with more fiber and small viscosity. In this way, the pretreatment procedures of raw material mixing and breaking can be eliminated, and the production links can be reduced. Because the trough type organic manure dumper runs on a fixed track, it is mostly driven by a motor, and its price is mainly related to its motor power.
