Description

Technical Field

[0001] The utility model relates to the field of auxiliary equipment of feed factories, in particular to a ventilation device for a batching bin. Background Art

[0002] Feed is made from a variety of raw materials through multiple processes, and in general feed processing plants, there are multiple batching silos to store the raw materials to be processed. These raw materials will be transported to the processing equipment through the feed pipe for processing;

[0003] The raw materials in the silo are generally pumped into the feed pipe for transportation. Therefore, the silo needs a certain degree of air permeability. If the silo is not equipped with a breathable cap, the dust concentration and temperature in the silo are high, which poses a safety hazard. At present, workers often install a breathable cover on the top of the silo and set air holes on the breathable cover to improve the air permeability of the silo. The air in the silo is mixed with various unpleasant gases and floating dust. These gases and dust are directly discharged into the workshop, which is easy to pollute the workshop and affect the health of the workers. Utility Model Content
