Environment-friendly suspended hot air furnace for coarse straw bran

Abstract

The invention belongs to the technical field of hot air furnaces, and discloses an environment-friendly suspended hot air furnace for coarse straw bran. The environment-friendly suspended hot air furnace comprises a bracket; a spiral auger, an air blower, a main combustion chamber, a secondary combustion chamber and a settling chamber are arranged on the bracket; a horizontal first air distribution plate is arranged in the main combustion chamber; the secondary combustion chamber is arranged on one side, far from the air blower, of the main combustion chamber; a first opening formed in the upper end of the first air distribution plate in the main combustion chamber; the settling chamber is formed in one side, far from the main combustion chamber, of the secondary combustion chamber; a hotair output pipeline is vertically fixedly connected to one side, opposite to a second opening, of the settling chamber; and igniters are arranged at the position where the main combustion chamber is positioned at the upper end of the first air distribution plate and the position where the secondary combustion chamber is positioned at a second air distribution plate. The environment-friendly suspended hot air furnace is simple in structure and high in environment-friendly performance, can be widely applied in the field of grain drying, and has obvious progressive significance.

Description

technical field [0001] The invention relates to the technical field of hot blast stoves, in particular to an environmentally friendly suspension hot blast stove with straw and chaff. Background technique [0002] All kinds of grains harvested in agriculture are subject to dehumidification and drying treatment, and the purpose of dehumidification and drying treatment is to reduce the internal moisture and reduce the water content in the grains. On the one hand, reducing the water content can reduce the self-respiration of the grains and consume energy; On the other hand, avoid grain germination and mildew caused by excessive moisture content. In the prior art, large-scale grain drying mainly adopts grain dryers, which have the advantages of short dehydration time and high drying treatment efficiency, effectively ensure the quality of grain storage, reduce the probability of grain mildew and germination, and play a vital role in ensuring food safety. It has played a vital rol...
