Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, are not to be construed as limiting the present invention.

As shown in figure 1, the kitchen waste aerobic fermentation device mainly comprises a crusher 2, a fermentation bin 1, a stirring mechanism, a ventilation mechanism and a microorganism throwing port 3. Kitchen garbage is fed from the upper part of the device and falls into the crusher 2 to be crushed, and the crushed garbage enters the fermentation bin 1. Aerobic microorganisms enter the fermentation chamber 1 through the microorganism putting port 3. The stirring mechanism rotates in the fermentation chamber 1 to uniformly mix the garbage and the aerobic microorganisms. A plurality of ventilation pipes 4 are inserted into the reaction bin, and a plurality of holes are formed in the pipe wall of each ventilation pipe 4, so that ventilation is enhanced, and materials can be uniformly and fully fermented. The temperature of the supplemented air is adjusted by a heater 9 and a flow controller 8 which are connected by a vent pipe, so that the temperature in the reaction chamber is kept at the optimal growth temperature of the microorganisms. Meanwhile, due to the existence of the ventilation pipe 4, the stirring of the materials is enhanced, and the full and uniform fermentation of the garbage is facilitated.

Rubbing crusher 2 is installed in the top of fermentation storehouse 1, and rubbish is less than 1cm through smashing the back particle diameter, carries out preliminary treatment (smashing) to rubbish from cooking and has further improved rubbish from cooking and aerobic microorganism's mixed degree, and the stirring is more even, and the fermentation is more abundant.

The device is also provided with a microorganism throwing system, the quality of the garbage entering the fermentation bin 1 is determined according to the quality difference monitored by the quality sensor 7 at the bottom of the fermentation bin 1, and microorganisms are manually thrown in according to a certain proportion based on the quality of the kitchen garbage.

The fermentation chamber 1 is composed of a chamber body, a stirring mechanism and a ventilation pipe 4. The smashed garbage and microorganisms are mixed and then carry out biochemical reaction in the fermentation bin 1, the ventilation pipe 4 is inserted into the fermentation bin 1, and air subjected to temperature adjustment is continuously fed into the fermentation bin 1, so that sufficient oxygen is ensured to exist in the fermentation bin 1, and meanwhile, the temperature in the fermentation bin 1 can be adjusted. The periphery of the fermentation chamber 1 is provided with a heating and heat-preserving system to ensure that the biochemical reaction is carried out at the optimal temperature. The fermented garbage is discharged through the discharge door 6 of the fermentation bin 1 and can be used as organic fertilizer.

In addition, the kitchen garbage aerobic fermentation device is in a closed state in the operation process, and gases generated by reaction are subjected to tail gas harmless treatment by the tail gas treatment device 12, so that no odor is discharged in the whole process.

The working principle is as follows:

the kitchen garbage enters a crusher 2, is crushed into proper granularity and then enters a fermentation bin 1. The quality sensor 7 determines the quality of the garbage entering the fermentation bin according to the quality difference before and after the garbage is thrown in. According to the quality of the garbage entering the warehouse, microbes with corresponding quality are put in from the microbe putting-in port 3. The stirring mechanism, namely a motor and a speed changer 11 are connected with the main shaft 5 to drive the paddle 13 to rotate, the mixture of the garbage and the microorganisms is stirred, and the driving device is set to stir for 5 minutes every 4 hours. Air is pressurized by a fan 10 and enters a heater 9, and enters the fermentation chamber 1 through a ventilation pipe 4 after being regulated by a flow controller 8, so that sufficient oxygen is obtained from the garbage. After 12-24 hours of fermentation, the discharge door 6 is opened to complete the garbage disposal of one batch.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
