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

Abstract

The invention belongs to the technical field of cow dung treatment in intensive cattle farms, and discloses a cow dung drying device, method and application based on a reinforced concrete structure, which transforms a bamboo-wood structure dry column building into a reinforced concrete structure; the building has a roof To prevent rain erosion, the cow dung part should be at an appropriate distance from the ceiling to achieve air circulation; the slatted floor and the ground should have a space distance of more than 2m to prevent moisture and achieve air circulation; an underground water collection pool should be set under the ground . Fill up with cow dung until dry. The invention can realize the drying of cow dung with a one-time amount exceeding 100 tons in the rainy and humid southern region. After less than one year, the water content of cow dung can be reduced from 85% to less than 16%, and the weight of cow dung can be reduced by more than 75%. After the dry cow dung is burned, the cow dung ash accounts for 3.5% of the weight of fresh dung. After drying and burning, the reduced production of 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
