Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a fermentation and drying device for treating kitchen waste. Background technique [0002] With the development of society and economy, the acceleration of urbanization, and the improvement of living standards, the amount of kitchen waste is increasing day by day, which has exceeded the self-purification ability of the earth and has become a worldwide public hazard: 1. Disease spread and gene mutation. Due to the similar gene sequences of vertebrates, eating each other can easily cause the spread of zoonotic diseases such as mad cow disease, foot-and-mouth disease, avian influenza, and SARS, as well as gene mutations and offspring developmental deformities caused by homologous gene pollution, which can easily induce cancer; 2. Resources waste. The annual output of kitchen waste in my country is about 60 million tons, which is equivalent to the annual p...

Problems solved by technology

[0004] In the prior art, there is a device that uses a biological fermentation tank to treat garbage. It is equipped with a stirring shaft in the fermentation tank. The upper end of the fermentation tank is provided with a feed port, and the lower side is provided with a raw material discharge port. The bottom of the fermentation tank is along the direction of the axis of the stirring shaft. There is an oxygenation gap, the air enters from the raw material discharge port of the mixing tank, and is discharged from the feeding port. The stirring shaft is provided with spiral blades to facilitate the mixing of garbage. The disadvantages are: unreasonable structure, cumbersome production, and The oxygenation gap is set at the bottom of the mixing tank, which is easy to block the material and cause insufficient oxygenation fermentation. The second is that the temperature of the mixing tank is not easy to control, and the fermentation time is not fixed, resulting in insufficient fermentation and extremely slow processing efficiency.

[0005] After retrieval, CN2730508A discloses a patent for the invention of a garbage sterilization and fermentation treatment device, which includes a treatment tank, a feeding device for feeding the treatment tank and a heat supply generator for supplying heat to the treatment tank, and the feeding device It is connected with the feed port of the processing tank, the processing pipe has a feed port at the top and a discharge port at the bottom, at least two agitators are arranged along the horizontal direction of the processing tank, and the inner layer of the processing pipe has a heat-conducting oil interlayer , the heating generator is connected with the heat transfer oil interlayer and the treatment tank. Although it solves the problem of uniform heating of the fermentation tank, the disadvantage is that the structure is complicated, the heating method is cumbersome, and the above-mentioned kitchen waste cannot be directly dried. During the aerobic fermentation process, an air heat pipe needs to be equipped to inflate the treatment tank for fermentation, resulting in slow processing speed and unsatisfactory fermentation effect. In addition, during the feeding process, manual feeding is required, resulting in the health of the workers not being guaranteed.
