Hot air furnace drying box

Abstract

The invention relates to a hot air furnace drying box. The hot air furnace drying box comprises a base, a hot air furnace arranged at the center of the base, a central air supply cavity communicated with the hot air furnace, a left ventilating and drying cavity, a right ventilating and drying cavity, a left ventilating tube, a right ventilating tube, top ventilating tubes arranged at the upper ends of the left ventilating tube and the right ventilating tube, and a centrifugal fan arranged at the upper portion of the central air supply cavity, wherein the left ventilating and drying cavity and the right ventilating and drying cavity are arranged at the left end and the right end of the central air supply cavity and communicated with the central air supply cavity through hot air inlets, and the left ventilating tube and the right ventilating tube are respectively arranged the end portions of the left ventilating and drying cavity and the right ventilating and drying cavity. The left ventilating and drying cavity and the right ventilating and drying cavity are respectively communicated with the left ventilating tube and the right ventilating tube through hot air outlets. The hot air furnace drying box is balanced in material drying and good in drying effect.

Description

technical field [0001] The invention relates to a hot blast stove drying box. Background technique [0002] At present, the known drying equipment for agricultural and sideline products has a structure that drying boxes are arranged on the left and right sides of the hot blast stove. The hot blast stove is a square box with closed sides and an opening at the top. The combustion furnace is placed below the square box. An axial flow fan is installed above the combustion furnace. An air inlet is provided under the partition adjacent to the left and right drying boxes. The air is forced to flow under the action of the fan. After being heated by the combustion furnace, the air enters the bottom of the left and right drying boxes from the above-mentioned air inlet, passes through the material layer in the drying box, and is discharged. The disadvantage of this technology is that it is different from the drying box. The temperature difference between the upper and lower sides is l...

Problems solved by technology

The hot blast stove is a square box with closed sides and an opening at the top. The combustion furnace is placed below the square box. An axial flow fan is installed above the combustion furnace. An air inlet is provided under the partition adjacent to the left and right drying boxes. The air is forced to flow under the action of the fan. After being heated by the combustion furnace, the air enters the bottom of the left and right drying boxes from the above-mentioned air inlet, passes through the material layer in the drying box, and is discharged. The disadvantage of this technology is that it is different from the drying box. The temperature difference between the upper and lower sides is large, the wind resistance of the hot air is large, and the flow rate is slow. The phenomenon that the material in the middle is cooked, the drying speed is slow, the drying cycle is long, the quality of the dried material is poor, and the energy consumption is high.
