Background

Garbage is a substance discarded by people in daily work, life and production, and the treatment method of human beings is landfill, incineration, composting and other technologies. However, the perishable garbage (kitchen, crop waste, human and animal excrement and the like) can cause air and underground water pollution and harm the ecological environment if being buried. If incineration is carried out, dehydration and drying are needed, the produced sewage needs to be treated, the calorific value rate of slag materials is low, the temperature of the incinerator can be reduced, and even the service life of equipment can be reduced. For example, natural compost is decomposed by microorganisms, but has large floor area, large space and heavy smell, and when the microorganisms are decomposed, a large amount of sewage and malodorous gas are generated, so that the natural water and air can be polluted if the microorganisms are not treated properly. Therefore, equipment for harmless, quantitative-reduction and resource treatment of perishable garbage is produced.

1. the garbage crushing capability is poor, the high-fiber garbage cannot be crushed, and the crushed particles are large, so that the microbial decomposition time is long.

2. The organic wastewater with a certain amount of high concentration is generated by mechanical extrusion dehydration, and if the organic wastewater is not treated, the organic wastewater is easy to pollute the environment and water sources.

3. The fermentation temperature rise is slow, the existing equipment adopts the external electric heating conduction temperature rise of the fermentation bin, the heat utilization rate is low, and the electric energy loss is large.

4. The microbial-free bed and some devices are also provided with the bacterial bed, but the total amount control device of the microbial bed during discharging leads to that a part of biological bacteria are taken out of the fermentation bin during discharging, so that the secondary fermentation is retarded due to the reduction of microbial biomass.

5. And (4) no rotten stage exists, and the material is dried and discharged within 24 hours, so that the product cannot meet the quality standard of the organic fertilizer.

6. The water vapor generated during the garbage fermentation is directly pumped and discharged by a fan, so that the temperature of the fermentation bin which should be kept warm is reduced, the fermentation rate is reduced, the treatment time is prolonged, and the electric energy is wasted.

An extrusion dehydrator is canceled, wet garbage directly enters a fermentation bin and is mixed with a biological bacteria bed 3 in the fermentation bin under the action of a stirrer 2, so that the material is dry and wet uniformly, the total water content is kept between 60 and 65 percent, the temperature of the material is controlled between 60 and 70 ℃, the most active period of microorganisms is reached, and organic matters in the garbage are rapidly degraded, decomposed and converted into amino acid and glucose. Rubbish can reach about 70 degrees at fermentation in-process material temperature, and moisture in the rubbish gasifies under high temperature, and the hot-air that 2 exhausts simultaneously carries out moisture to the material of stirring in-process and blows off, and a large amount of vapor gushes towards the condensation chamber 5 on fermentation cabin upper portion, makes steam separation become distilled water and air, and the clean distilled water after the separation is automatic to be discharged escape canal 7 and directly discharges, and the air then discharges into air purifier through the blast pipe 6 at fermentation cabin top and purifies. After the garbage to be treated is treated by a series of processes of the equipment, the reduction rate can reach 90-95%. Garbage can be thrown in continuously for at least 1 week, automatic discharging is once after a week, the pneumatic discharge door 14 is opened during discharging until no material is discharged, the pneumatic discharge door 14 is automatically closed after discharging, and the equipment continues to process garbage in a reciprocating and circulating manner.

Finally, it should be noted that: the present invention is not limited to the above embodiments, and all the equivalent structures or equivalent processes that are used in the specification and the attached drawings are transformed or directly or indirectly used in other related technical fields, and all the same principles are included in the protection scope of the present invention.
