Problems solved by technology

The direct dumping of garbage will cause serious pollution to the rural ecological environment. Flies are flying around on the garbage dump, and the smell is piercing the nose. Harmful substances in the garbage will seep into the soil along with the rain, and finally flow into the groundwater, endangering people's health.
Due to the lack of suitable treatment methods and facilities, rural yard waste has not been effectively treated

Embodiment 1

[0027] The mixed materials are input from the feed port 1 of the primary fermentation chamber 2, and the primary fermentation is carried out in the primary fermentation chamber 2. During the fermentation process, a small amount of leachate will be produced, and the leachate will be gradually discharged from the drain hole 6 of the drawing plate 7 In the second fermentation bin 8, this part of the leachate can supplement appropriate water for the second fermentation. The fermentation period of the material in the primary fermentation bin is 20-25 days, and the vents designed on the primary fermentation bin will be realized by natural ventilation. For the gas exchange of material biological fermentation, when the seesaw moves, the material in the primary fermentation chamber will reciprocate and evenly move. In this process, the oxygen supplement of the material microenvironment can be realized, and the compaction caused by material fermentation can be reduced. Accelerate the pri...

Embodiment 2

[0030] In this example, kitchen waste and plant waste, which are the most produced by households, are selected as the main composting materials. First, use a household scale to weigh out 20-25kg of kitchen waste and 15-20kg of plant waste. The plant waste is simply crushed with a small guillotine. The components of the two types of waste are as follows (the sample data from different sources may vary, roughly smaller than float):

[0031] Food waste, organic carbon content 46.79%; total nitrogen content, 2.60%;

[0032] Plant waste: organic carbon content 48.24%, total nitrogen content 1.2%.

[0033] The mixed yard waste is sent into the primary fermentation bin 5 for biological fermentation. Generally, the temperature rises to 60°C in 2-4 days and is maintained for 5-8 days. After 20-25 days of primary fermentation, the temperature gradually decreases to 60°C. Ambient temperature (the temperature change of primary fermentation such as figure 2 Shown), so the temperature o...

Abstract

The invention discloses a courtyard seesaw type organic garbage composting device. The upper part of a primary fermentation bin is provided with a feeding hole, two side faces are provided with air vents, and the bottom is provided with an opening and a drawing plate; a liquor discharge hole is formed on the drawing plate; a secondary fermentation bin is a tank body, the bottom has an arc shape, and one side face of the bottom is provided with discharge holes and air vents; the primary fermentation bin is fixed on the middle of a seesaw, and the secondary fermentation bin is fixed below the middle of the seesaw; the seesaw is provided with an opening corresponding to the opening at the bottom of the primary fermentation bin; and the primary fermentation bin is communicated with the secondary fermentation bin through the opening of the seesaw. Through vertical fluctuation of the seesaw in the using process, materials in the fermentation bins are turned and stirred in a reciprocating mode to achieve the effects of ventilating, loosening the materials and mixing uniformly; and after primary fermentation is finished, the materials in the primary fermentation bin are discharged, namelythe drawing plate is opened and the materials enters the secondary fermentation bin for secondary fermentation, and the aim of quickly fermenting organic matters such as domestic garbage, garden garbage and the like into a domestic organic fertilizer is fulfilled finally.

Description

technical field [0001] The invention belongs to the field of resource utilization and research of solid waste, and relates to a reactor for biological fermentation of solid waste, specifically an organic waste composting device that can be turned and mixed by using a garden seesaw. Background technique [0002] Composting is the use of microbial activities to decompose perishable organic substances in garbage and transform them into organic fertilizers that are rich in organic matter and contain a certain amount of nitrogen, phosphorus, potassium and other nutrients and trace elements, turning garbage into a resource in agriculture. It is used in landscaping and landscaping, and it has received more and more attention because it conforms to the overall strategy of sustainable development in the world today. The design of the reactor in the composting process has always been a research hotspot in this field. The use of a scientifically designed and reasonable composting react...
