Cow dung drying device, method and application based on reinforced concrete structure

Abstract

The invention belongs to the technical field of intensive cattle farm cow dung treatment, and discloses a cow dung drying device, method and application based on a reinforced concrete structure. A bamboo wood structure dry-bar type building is transformed into the reinforced concrete structure; the building is provided with a ceiling for blocking rainwater erosion, and a proper distance is kept between a cow dung part and the ceiling so as to realize air circulation; a drain seam floor of the cow dung part has a spatial distance of more than 2 m from the ground, so that the functions of preventing moisture and realizing air circulation are realized; and a ground lower water collection pool is arranged below the ground. Cow dung is filled until dry. According to the cow dung drying device,the drying of the cow dung once 100 tons or above can be realized in a multi-rain wet southern region. The water content of the cow dung can be reduced from 85% to 16% or below for less than 1 year, the weight of the cow dung is reduced by 75% or above, and after the dry cow dung is burned, the cow dung ash accounts for 3.5% of the fresh dung weight. After the cow dung is dried and burned, the reduction production of the cow dung can be realized.

Description

technical field [0001] The invention belongs to the technical field of cow dung treatment in intensive cattle farms, and in particular relates to a cow dung drying device, method and application based on a reinforced concrete structure. Background technique [0002] At present, cow dung composting technology is the most common technology for cow dung treatment. Pile cow dung directly on open land, which is low in cost and large in processing capacity, but it is easy to pollute groundwater, and rainfall is likely to cause large-scale pollution. Not applicable in the South. Cow dung organic fertilizer production technology, the water content is generally above 60%, the labor cost and transportation cost are relatively high, and the fertilizer efficiency is relatively low. Cow dung rapid drying technology consumes a lot of energy, and the air pollution is particularly serious, so this option has been ruled out. Cow dung dry-wet separation technology, the solid part of cow dun...

AI Technical Summary

Problems solved by technology

[0003] In summary, the existing problems in the prior art are: the current cow dung composting treatment method has high water content in cow dung, high transportation cost of cow dung, low efficiency of cow dung fertilizer, difficulty in use, and easy to cause water pollution
