Technical Field

The utility model relates to the technical field of dryers, in particular to a disc dryer with a preheating device.

Background Art

The disc dryer is a drying equipment that uses a high-temperature drying disc to turn and dry the material. It uses a drying disc and a rake arm to rotate on the upper side of the drying disc to turn and move the material, thereby completing the drying of the material. The disc dryer dries through the turning of the rake arm, allowing the material to continuously fall from the upper side of the small drying disc on the top of the dryer, tumbling and drying the material, and finally falling to the bottom of the dryer. The discharging mechanism sends the dried material out from the bottom of the disc dryer to obtain a dried product.

Publication (announcement) number: CN219756870U, discloses a disc dryer with a preheating function, by providing a feed hopper on the top of a protective cylinder, and providing a preheating bin connected to a steam connecting pipe at the position where the protective cylinder is connected to the feed hopper, and a fixed partition rotating inside the preheating bin, so that the exhaust gas after being utilized by the drying disc can be directly discharged into the preheating bin to directly heat the feed hopper, and the material inside the feed hopper is preheated, thereby reducing the conduction of the intermediate medium, improving the utilization rate of heat energy, avoiding the waste of heat energy, being able to preheat the material inside the feed hopper more efficiently, and improving the practicality of the device.

In the above patent, the feed hopper is heated by steam exhaust gas, but the material cannot be effectively and evenly preheated during the falling process, thereby failing to achieve the preheating effect of the material. In addition, the discharge of the material after drying is prone to blockage, which reduces the discharge efficiency of the material. Therefore, it is necessary to provide a disc dryer with a preheating device.
