Household kitchen waste fermentation and recovery device

Abstract

The invention discloses a household kitchen waste fermentation and recovery device comprising a base; a fermentation tank, wherein the bottom of the inner wall of the fermentation tank is fixedly provided with a filtrate plate by bolts, the surface of the filtrate plate is evenly provided with waste liquid through holes, the inside of the fermentation tank is slidably provided with a pressing plate, the outside of the pressing plate is symmetrically and fixedly provided with sliding blocks through bolts, and sliding grooves matched with the sliding blocks are symmetrically formed in the innerwall of the fermentation tank; a waste liquid bucket, wherein the center of the bottom of the waste liquid bucket is in threaded connection with a drain pipe; a hardware control system further including a control module, a power supply module, a timing module and a warning module. The waste liquid bucket is fixedly mounted at the bottom of the fermentation tank by bolts. When no waste liquid is left in the waste liquid bucket, the control module controls a self-control valve to be closed, so that not only the kitchen waste can be separated from the waste liquid, but also the external air is prevented from entering the fermentation tank from the drain pipe, and normal fermentation of the kitchen waste can be ensured.

Description

technical field [0001] The invention relates to the technical field of kitchen waste recycling, in particular to a household kitchen waste fermentation recovery device. Background technique [0002] Kitchen waste includes fish bones, leftovers, leftovers, vegetable leaves, etc. In a narrow sense, kitchen waste generally refers to raw materials and finished products (cooked food) or residues required in family life and diet. It is divided into cooked kitchen waste including leftovers. food, leftovers, etc.; raw kitchen waste includes fruit peels, eggshells, tea residue, etc.; broadly defined kitchen waste also includes used chopsticks, food packaging materials, etc. [0003] The moisture content in kitchen waste is as high as 74%. In addition, the salt (sodium chloride) in kitchen waste is high. If kitchen waste with such a high moisture content is directly mixed with other waste and landfilled, it will be destroyed under the action of high pressure and microorganisms. Form ...

AI Technical Summary

Problems solved by technology

[0005] 1. The existing kitchen waste recycling equipment cannot completely separate the kitchen waste from the waste liquid, thus affecting the further fermentation of the kitchen waste, causing the fermented kitchen waste to still decompose and produce stench, and release a large amount of waste into the atmosphere Pollutants such as ammonia and sulfide

[0006] 2. After the kitchen waste is put into the recycling equipment, some kitchen waste is relatively soft, which will take up a lot of space and reduce the storage space of the recycling equipment. In this way, the kitchen waste fermented by the recycling equipment at one time is relatively limited, reducing the amount of kitchen waste. Waste Fermentation Efficiency
