Environmental-friendly dust collecting room for grain drier

Abstract

The invention discloses an environmental-friendly dust collecting room for a grain drier, which comprises a box body (1), wherein a filter screen group used for dividing an inner cavity of the box body (1) into an upper chamber (1.1) and a lower chamber (1.2) is set inside the box body (1); the lower chamber (1.2) is provided with an inlet (1.3); the upper chamber (1.1) is provided with an outlet (1.4) used for the discharged waste gas inside the lower chamber after the waste gas passes through the filter screen group; and the environmental-friendly dust collecting room for the grain drier is characterized in that the filter screen group comprises an initially filtering filter screen and a top-layer filter mechanism (5) set above the initially filtering filter screen. The invention provides an environmental-friendly dust collecting room for a grain drier that is capable of filtering waste gas discharged from the grain drier with high efficiency to eliminate dust particles and impurities in the waste gas.

Description

technical field [0001] The invention relates to the technical field of grain drying machines, in particular to an environment-friendly dust collection room for grain drying machines. Background technique [0002] The process of grain from harvesting to storage requires drying of the grain to facilitate subsequent processing or long-term storage of the grain. The heat pump grain dryer has the advantages of less pollution, low energy consumption and low cost compared with the traditional dryer by burning fuel. Therefore, there are more and more heat pump grain dryers in the prior art. Dryers used to replace traditional fuel-burning methods. For example, the application publication number is the patent application of the heat pump drying equipment of CN103438682A. [0003] However, in the grain dryer of the prior art, the hot air supplied by the heat pump passes through the drying layer to dry the grain, and the exhaust gas discharged carries a large amount of dust particles ...

AI Technical Summary

Problems solved by technology

[0003] However, in the grain dryer of the prior art, the hot air supplied by the heat pump passes through the drying layer to dry the grain and the waste gas discharged carries a large amount of dust particles such as chaff, and direct discharge will cause air pollution, which will not only affect the operators personal health, and cannot meet the production environmental protection requirements stipulated by the state
