Anti-dewing device for inner walls of steel silos

Abstract

The invention discloses an anti-dewing device for the inner walls of steel silos. The anti-dewing device includes a ventilation pipe which is installed on the side wall of a steel silo and has one endinserted into an air distribution chamber at the bottom of the steel silo. The ventilation pipe has a first pipe cavity extending axially and a second pipe cavity extending axially. The first pipe cavity is located on the outer side of the second pipe cavity. Multiple fish scale holes used to guide the dry air in the air distribution chamber to the side wall of the steel silo are formed in the side wall of the first pipe cavity. An air intake passage connected with the outside is arranged on the side wall of the second pipe cavity, and a negative pressure generator is installed inside the second pipe cavity. Dewing on the inner wall of a steel silo can be prevented, and the problem of dewing on the inner wall of the existing steel silo during grain storage is avoided.

Description

technical field [0001] The invention relates to the technical field of material bin drying, in particular to an anti-condensation device on the inner wall of a steel bin. Background technique [0002] During the storage of grain in the steel silo, the moisture content of the grain itself will change with the change of the ambient temperature and humidity. Especially in the season when the temperature difference between day and night is large, when the outside temperature is lower than the temperature inside the warehouse, the low temperature outside will cause the warm and humid air in the warehouse to condense on the inner wall surface of the cold steel warehouse, which will cause the surrounding grain to be affected by moisture. wet. From autumn to winter, as the outside temperature continues to drop, the wet grain will freeze on the inner wall of the steel silo, and then the next spring will come, and the outside temperature will rise accordingly, so the frozen grain wil...

AI Technical Summary

Problems solved by technology

The mildew of the grain not only causes the loss of grain and damages the quality of grain processing, but also the mildewed grain attached to the inner wall of the steel silo will cause the galvanized layer of the inner wall of the steel silo to rust and fall off, reducing the structure of the steel silo and shortening the use of the steel silo life
