Description

Technical Field

[0001] The utility model relates to the technical field of shallow silos, in particular to a multifunctional central tube and radial ventilation device for shallow silos. Background Art

[0002] Shallow silos have the characteristics of large single-bin capacity, small footprint, slow heat exchange between the grain pile and the outside world, high degree of automation and low construction cost. However, since shallow silos still load grain from the top of the silo, the grain falls from more than ten to thirty meters in the silo. Under the influence of its own gravity, the grain is easily damaged by falling when entering the silo and is squeezed during the grain entry process. In addition, the silo contains some impurities, and the automatic grading phenomenon during the grain entry process is also relatively serious. After continuous research, it was found that a multifunctional central tube and radial ventilation device were set in the silo.

[0003] For example, the utility model patent with publication number CN218353350U, titled "A Multifunctional Circulation Ventilation Device for a Shallow Silo", with authorization announcement date of 2023.01.24, includes a shallow silo; a ventilation drop pressure reducing pipe is provided inside the shallow silo, the ventilation drop pressure reducing pipe includes a drop pipe and a ventilation pipe, and the ventilation pipe array is distributed outside the drop pipe, a bridge hole is opened on the bottom 1 / 2 section of the drop pipe, the top of the ventilation pipe is connected to a dust explosion-proof circulation fan through a conduit, and the bottom of the ventilation pipe is fixedly connected to a guide pipe. Flow component, in the utility model, ventilation is carried out in the shallow circular silo by sending air flow into the ventilation trough connected to the bottom end of the ventilation pipe, and the gas slowly penetrates through the grain pile to the top of the grain surface, thereby realizing circulating ventilation of the grain silo. When a temperature difference is formed between the grain pile and the ventilation pipe, water droplets are generated on the inner wall of the ventilation pipe. By converting the diversion component connected to the bottom end of the ventilation pipe, the ventilation trough connected to the diversion component is converted to a drainage pipe. Under the action of the fan, the water droplets on the inner wall of the ventilation pipe are discharged to avoid water droplets from mixing into the grain pile during ventilation, thereby affecting the quality of the grain pile.
