Straw grinding stirring drying device

Abstract

The invention provides a novel straw crushing, stirring and drying device, which belongs to the technical field of mechanical equipment. It includes a crushing device (3), a stirring and drying device (6), a dehumidification device (9) and an air heating device (10); the crushing device (3) is fixed above the inside of the crushing box (1); the stirring and drying device (6) Welded on the four supporting columns (7); the dehumidification device (9) is fixedly installed on the right side of the upper end of the stirring drying box (61) in the stirring drying device (6); the air heating device ( 10) Fixedly installed on the right side of the upper end of the stirring drying box (61) in the stirring drying device (6), on the right side of the dehumidification device (9). The novel device of the invention has high crushing quality of straw, and after crushing, the straw is stirred and dried, and the air in the stirring drying box is extracted to carry out circulating hot air drying, thereby ensuring the drying efficiency of the straw, and the dried straw is convenient for storage.

Description

technical field [0001] The invention relates to a new type of mechanical equipment, in particular to a straw crushing, stirring and drying device. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops, usually referring to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource, and straw is also a roughage; its characteristics are The crude fiber content is high (30%-40%), and contains lignin, etc. Although lignocellulose cannot be used by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock. The traditional processing of straw Most of the methods are used for incineration. St...

Problems solved by technology

More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource, and straw is also a roughage; its characteristics are The crude fiber content is high (30%-40%), and contains lignin, etc. Although lignocellulose cannot be used by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock. The traditional processing of straw Most of the methods are used for incineration. Straw incineration causes smog weather and produces a large amount of toxic and harmful substances, posing a threat to human and other biological health.
