Corn drying device adopting biomass formed fuel hot blast furnace

Abstract

The invention discloses a corn drying device adopting a biomass formed fuel hot blast furnace. The structure of the corn drying device comprises a feed hopper, a drying box, a draught fan and an exhaust fan; the feed hopper is installed at an upper end opening of the drying box; the draught fan is arranged at one side of the drying box; the exhaust fan is arranged at the other side of the drying box; the feed hopper extends into the drying box and respectively consists of a feed chamber, a cutting disc, a scraping cone and a negative-pressure cutting mechanism; the feed chamber is divided intoa reversed V-shaped structure by a cutting system which consists of the cutting disc, the scraping cone and the negative-pressure cutting mechanism; the feed chamber of the corn drying device disclosed by the invention is of a reversed V-shaped structure; the scraping cone is used for separating stems and leaves of the to-be-separated corns; the leaves are discharged via the two sides, while thestems are slit into segments under the effect of the cutting disc which cooperates with a triangular cutting knife so as to form small segments of corn stems, and thus the internal moisture emission area is increased, the drying effect in the later period is effectively improved, and waste of resources in later-period drying can be effectively alleviated by virtue of the separation of the stems and the leaves.

Description

technical field [0001] The invention relates to biomass energy, in particular to a biomass briquette fuel hot stove corn drying device. Background technique [0002] In order to promote the full utilization of resources and reduce air pollution, the utilization method of biomass briquette fuel is widely used at present to solve the problem of grain drying and the full utilization of agricultural waste. In the utilization of biomass, corn is one of the grain varieties that are difficult to dry , mainly because its grain is large and uneven in size, the unit specific surface area is small, and the structure of corn skin is compact and smooth; [0003] Existing technologies generally use external dry moisture to degrade, which is not conducive to the evaporation of moisture from the inside of the corn to the outside; [0004] Moreover, corn has different components of stalks and leaves. If the stalks and leaves are dried at the same time, the drying energy required will be dif...

AI Technical Summary

Problems solved by technology

[0003] Existing technologies generally use external dry moisture to degrade, which is not conducive to the evaporation of moisture from the inside of the corn to the outside;

[0004] Moreover, corn has different components of stalks and leaves. If the stalks and leaves are dried at the same time, the drying energy required will be different, which will waste resources to a large extent;

[0005] Furthermore, increasing the drying temperature due to the moisture content of the dried corn will greatly reduce the quality of the dried corn.
