[0002] In the current drying tower, during the drying process of wheat, corn and other granular materials to be dried, the grain is usually raised to the top of the drying tower, and then the grain is sprinkled from the inlet at the top of the drying tower to the drying tower. The outlet at the bottom of the tower, while the hot air enters the tower cavity directly from one side of the drying tower and discharges the moisture from numerous triangular vents in the tower cavity. However, the hot air in the drying process will be directly discharged from the triangular hole of the drying tower, and the hot air only penetrates the object to be dried once, so the utilization rate of the hot air is low. big energy waste problem

Embodiment Construction
[0018] Referring to the accompanying drawings, the energy-saving drying tower with all hot air recovery includes a vertically arranged drying cylinder 3 with a material inlet 1 at the top and a material outlet 2 at the bottom, wherein the top opening of the drying cylinder 3 can be It directly constitutes the material inlet 1, therefore, the material can be discharged from the top of the drying cylinder 3 into the cylinder cavity through the elevator, and the bottom of the drying cylinder 3 can be a tapered discharge opening 2 with a large upper end and a smaller lower end. Therefore, the materials can be discharged concentratedly on the conveyor belt or other elevators; in addition, the drying cylinder 3 can be a cylindrical cylinder, of course, the present invention preferably adopts a rectangular cylinder.
[0019] Continuing to refer to accompanying drawing, this drying cylinder 3 is provided with a plurality of interlayers arranged at intervals up and down, certainly, the ...

The invention discloses an energy-saving drying tower realizing complete recovery of hot air. The drying tower comprises a vertical drying cylinder, wherein a feeding opening is formed in the top of the drying cylinder, a discharging opening is formed in the bottom of the drying cylinder, multiple spacing layers which are arranged vertically at intervals are arranged in the drying cylinder, a cavity of the drying cylinder is divided into multiple vertically independent drying cavities by the multiple spacing layers, and vertically through blanking holes and sealing plates capable of adjustingopening size of the blanking holes are uniformly arranged on the spacing layers; and a blast heating device capable of heating hot air in the lower drying cavity and then blowing the hot air into theupper drying cavity is mounted between every two vertically adjacent drying cavities. The drying tower is simple in structure and convenient to use, can increase the utilization rate of the hot air and reduce the energy consumption, can increase the drying efficiency and the drying uniformity and can prolong the retention time of materials in the tower cavities.
