Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of organic waste recycling, and particularly relates to an organic waste slurry fermentation device and method. BACKGROUND

[0002] Organic waste is widely sourced, including household kitchens, restaurants, hotels and other food processing-related industries, mainly including various fruit shells, vegetables, animal bones, leftover food, and other food residues; crop straw, and vegetable waste. Due to the lack of strict garbage classification in China, a large amount of organic matter that can be used for fermentation treatment is contained in ordinary household garbage.

[0003] For all these available organic matter, the common utilization means is to carry out fermentation treatment. Under suitable conditions of temperature, moisture and oxygen, aerobic or anaerobic microorganisms rapidly reproduce, and the garbage begins to decompose, converting various organic matter into harmless organic fertilizer for utilization. During the fermentation treatment of the organic matter, a corresponding fermentation device is used. The existing fermentation device cannot uniformly stir the waste, affecting the waste fermentation effect. SUMMARY

The inside of the shell is provided with a fermentation cavity. The cover is covered above the fermentation cavity. The feeding pipe penetrates the cover and communicates with the fermentation cavity. The discharging pipe communicates with the fermentation cavity. The motor is arranged on the cover. One end of the shaft is fixedly connected with the output end of the motor. The other end of the shaft penetrates the cover and is inserted into the fermentation cavity. The stirring assembly comprises two stirring parts, which are symmetrically arranged along the axial center line of the shaft.

The other end of the lower crushing knife is fixedly connected with the lower side knife. The lower side knife is perpendicular to the lower crushing knife. The upper crushing knife and the lower crushing knife are connected through the connecting piece.

[0007] The waste is added into the fermentation cavity through the feeding pipe, and then the motor is started to drive the shaft rod to rotate, thereby driving the stirring assembly to rotate. The upper and lower crushing knives are arranged in an up-down manner, which can fully crush the waste in the fermentation cavity. The upper and lower knives can further crush the waste, and the waste is uniformly stirred. The connecting piece can further uniformly stir and mix the waste. Then, the waste is subjected to static fermentation, thereby improving the waste fermentation effect. After the fermentation is completed, the waste is discharged from the discharge pipe.

[0014] The stirring assembly further comprises an inclined knife. The inclined knife is fixedly connected with the cutting knife and located at one end of the cutting knife away from the shaft rod.

[0015] The arrangement of the inclined knife can stir and crush the waste close to the inner wall of the fermentation cavity, so that the waste in the fermentation cavity is more uniformly mixed.

[0016] The shell further has a heating cavity and a plurality of installation openings in communication with the heating cavity. The heating cavity is filled with heat-conducting oil, and each installation opening is provided with a heating assembly.

[0017] The heat-conducting oil is heated by the heating assembly, and heat is transferred to the fermentation cavity, while an air inlet fan capable of inputting air is arranged on the cover, so that the required conditions of high-temperature aerobic fermentation are met, and the function of converting organic waste into organic fertilizer is realized.

[0018] The heating assembly comprises a mounting seat and a heating rod, one end of the heating rod is fixedly connected with the mounting seat, and the other end of the mounting seat is in contact with the heat-conducting oil.
