Circulation air drying equipment for organic fertilizer production

Abstract

The invention provides circulation air drying equipment for organic fertilizer production. The circulation air drying equipment comprises a tank body; the tank body is a top-opened hollow cylinder andis arranged vertically; a top cover is arranged at the top opened part of the tank body; a feed pipe is welded and fixed to the right side of the top cover; a dehumidification device is arranged on the left side of the surface of the top cover; a drying cavity is formed in the tank body; a drying device is arranged in the drying cavity; two turnover devices are symmetrically welded and fixed to the outer walls of the tank body; and a discharge pipe and brackets are welded and fixed to the bottom surface of the tank body. Through the drying device, an organic fertilizer added from the feed pipe and an overturned organic fertilizer are uniformly distrubuted, so that the dropping area of the organic fertilizer is increased; blown-in hot air is rotationally and uniformly distributed, so thatthe organic fertilizer is in full contact with the hot air, and the drying evenness of the organic fertilizer is improved advantageously; and through the turnover devices, circulation stirring of theorganic fertilizer in the vertical direction is realized, and the drying quality of the organic fertilizer is improved advantageously.

Description

technical field [0001] The invention relates to an organic fertilizer production equipment, in particular to a circulation air-drying equipment for organic fertilizer production. Background technique [0002] Organic fertilizers are mainly processed from biomass, animal and plant waste, and plant residues. Organic fertilizers are rich in a large number of beneficial substances, including a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. nutrient. The main function of organic fertilizer is to apply it to the soil to provide nutrition for plants, and it can not only provide comprehensive nutrition for crops, but also has a long fertilizer effect, which can increase and renew soil organic matter, promote microbial reproduction, and improve soil physical and chemical properties and biological activity. Key nutrients for green food production. Organic fertilizer contains a lot of water, which is not convenient for direct sto...

AI Technical Summary

Problems solved by technology

At present, the main way to dry organic fertilizer is to use a drum dryer. When drying organic fertilizer, the organic fertilizer is easy to adhere to the inner wall under the action of centrifugal force when the drum rotates, resulting in uneven heating of the organic fertilizer. , and the organic fertilizer is easy to accumulate inside the drum, resulting in insufficient drying of the organic fertilizer
