Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum dryers, in particular to an organic vacuum dryer. Background Art

[0002] Vacuum drying equipment is a highly efficient and energy-saving intermittent drying equipment. It uses conduction heating to remove liquids and moisture (solvents) from materials. When the material is in a vacuum state, the vapor pressure drops, causing the moisture (solvent) on the surface of the material to reach a saturated state and evaporate, and is promptly discharged and recovered by the vacuum equipment; the moisture (solvent) inside the material continuously penetrates to the surface, evaporates, and is discharged. The three processes are carried out continuously, and the material is dried in a very short time, that is, a higher drying rate is obtained with a lower temperature.

[0003] In summary, during the operation of the vacuum dryer, the moisture on the surface of the material needs to be continuously evaporated. Therefore, it is necessary to ensure that there is enough space around the material to improve the efficiency of moisture flow and discharge. However, the actual situation is that most of the dry materials are in a stacked state, and the contact surface between each material particle and the receiving plate is relatively fixed. In this way, the situation after drying is that the moisture on the contact surface is not completely evaporated; and after the moisture on the surface of the bottom material evaporates and rises, it will contact the upper material, thereby further reducing the moisture drying efficiency, so it needs to be improved.

[0026] Among them, due to the setting of the material guide rack 4, with the cooperation of the driving mechanism 7, the continuously poured material can be laid on the first conveyor belt 5 and the second conveyor belt 6 more evenly, and then under the action of the material brush 10, the continuously conveyed material can be rolled to ensure that its surface can fully contact the air, so that the evaporated water on its surface can quickly flow into the air; and with the cooperation of the material receiving trough 42 and the material guiding trough 43, it can be ensured that the material falling on the first conveyor belt 5 can cover the first conveyor belt 5, which not only improves the effective utilization rate of the first conveyor belt 5, but also ensures that the incoming material can be well spread on the first conveyor belt 5 to avoid local accumulation.
