Problems solved by technology

The tower is generally divided into multiple layers, and the organic materials are piled up on each layer of the tower for fermentation, and the organic materials fall from the upper tray to the lower tray by gravity, but it is easy to compact the material, resulting in a lack of oxygen in the pile; the material is discharged using a flap Or the spiral discharge method, affected by the moisture and corrosion of the material, the material is prone to arching and cannot be discharged normally, and the flap or spiral is easy to corrode, and the maintenance cost of the equipment is high

Embodiment 1

[0046]Take the daily treatment of 10 tons of wet chicken manure as an example. The initial moisture of wet chicken manure is 80%. Need to add 5 tons of bran and 5 tons of peat soil for seasoning. After mixing, the moisture content of the material is about 50%. According to the method of direct inoculation of biological bacteria agent at a ratio of 1 / 1000, the bacteria are purchased commercial bacteria agents, mainly composite bacteria agents containing yeast, Bacillus megaterium and lactic acid bacteria. After the three materials are uniformly transported and mixed together by the speed-adjusting auger, the liquid compound bacterial agent is sprayed, and the spraying amount is 1 / 1000 of the total weight of the organic material. The inoculated organic material is lifted to the conveyor belt at the top of the fermentation bin by the elevator. On the top, enter the fermentation chamber through the feed port. From the second day after feeding the material for fermentation, the ...

[0048] Take the daily treatment of 10 tons of wet chicken manure as an example. The initial moisture of wet chicken manure is 80%. Need to add 5 tons of dry organic materials and 5 tons of fermented clinker. After mixing, the moisture content of the material is about 50%. The three materials are evenly conveyed and mixed together by the speed-adjusting auger, then lifted to the conveyor belt on the top of the fermentation bin by the hoist, and enter the fermentation bin through the feeding port. During the period, due to the use of recycled material as inoculation, the inoculation amount was about 25%. From the second day after feeding the material for fermentation, the fermentation temperature has reached above 60°C, and it only takes about 15 hours for the fermentation temperature of the material to rise from the initial temperature of 40-45°C to 60°C. During the entire fermentation period, the material temperature is mostly above 70°C, and the highest temperature reaches...

Abstract

The invention relates to a vertical fermentation bin and a fermentation process thereof. The vertical fermentation bin comprises a bin wall, a bin top, an air suction opening, a feed inlet, a discharge outlet, transverse beams, a hydraulic system, a belt conveying system and an air supply system. The fermentation process comprises the steps of material mixing, inoculation, lifting, fermentation and discharging. Since the transverse beams are arranged in the fermentation bin at intervals and are used for reducing the weight of materials during falling from the top, the materials are prevented from being compacted and the situation of oxygen deficit of compost is avoided; and since the hydraulic system is combined with a scraping plate for discharging, the materials are not apt to form material arches, the discharged materials are even, the equipment is not apt to be corroded, the maintenance cost is low, the production process is easy to control, the fermentation period is short and the product quality is stable.

Description

technical field [0001] The invention relates to the field of organic waste treatment, in particular to a vertical fermentation bin and a fermentation process thereof. Background technique [0002] Organic materials are placed in buildings, containers or reactors, and the materials are decomposed by forced ventilation and mechanical turning. Including warehouse type, tower type and drum type fermentation process. The tower is generally divided into multiple layers, and the organic materials are piled up on each layer of the tower for fermentation, and the organic materials fall from the upper tray to the lower tray by gravity, but it is easy to compact the material, resulting in a lack of oxygen in the pile; the material is discharged using a flap Or the spiral discharge method, affected by the moisture and corrosion of the material, the material is prone to arching and cannot be discharged normally, and the flap or spiral is easy to corrode, and the maintenance cost of the ...
