Household garbage fermentation and fertilizer making device and method

Abstract

The invention discloses a household garbage fermentation and fertilizer making device and method. A device body is a fermentation bin. A feed inlet and an air outlet are formed in the upper portion of the fermentation bin. A feeding baffle is arranged at the feed inlet. The lower portion of the fermentation bin is provided with a liquid outlet used for draining percolate and a discharge outlet used for outputting fermented materials. A breaking device is arranged in the fermentation bin and composed of a plurality of sets of breaking blades distributed in a cross shape, and has two perpendicular rotary dimensionalities. Household garbage to be treated passes through a spiral conveying machine through the feed inlet to enter the fermentation bin where a hot water pipeline is laid, is broken and fermented and then enters a dehydration pelleting and drying system from the position of a discharge baffle. According to the household garbage fermentation and fertilizer making device and method, breaking, stirring, heating, fermentation, dehydration pelleting and drying are integrated, garbage is converted into fertilizer, the energy is nature is effectively utilized, the running cost is reduced, the resources are effectively utilized while the environment problem is solved, the garbage is made profitable, and a new approach for effectively treating household garbage is provided.

Description

Technical field [0001] The invention belongs to the field of solid waste treatment technology and resource utilization, and specifically relates to a domestic waste treatment and utilization fermentation fertilizer production device and a method thereof. Background technique [0002] In recent years, with the development of my country’s social economy, the acceleration of urbanization and the rapid improvement of people’s living standards, the discharge of domestic waste has continued to increase. A large amount of domestic waste has been discarded in the environment, which has exceeded the natural absorption capacity of the environment. , It will seriously endanger the ecological environment and people’s health. Therefore, properly handling the large-scale and wide-ranging pollution of domestic waste has become an important problem to be solved urgently in today’s society. [0003] At present, the treatment of domestic waste is mainly based on landfill and incineration. However, l...

However, the traditional composting method is to pile up a large amount of organic matter in the fermentation tank or on the open space for fermentation. This method not only occupies a large area, but the fermentation time is limited by the season and climate, and it will release unpleasant odor during the fermentation process. Foul smell, affecting the environment of the surrounding area
