[0002] A rubber powder cooling device is a specialized piece of equipment designed to cool rubber powder. Its purpose is to ensure the powder maintains stable physical and chemical properties during subsequent processing or storage by rapidly lowering its temperature. This device typically employs an air-cooled or water-cooled system, using forced air circulation or cooling water flow to quickly cool the high-temperature rubber powder to a suitable temperature. During the cooling process, the device is internally designed with evenly distributed guide plates or agitators to ensure uniform heating of the powder and prevent localized overheating or agglomeration. Traditional cooling air duct structures often lack uniform airflow distribution, leading to localized overheating or agglomeration of the rubber powder. Agglomerated powder negatively impacts subsequent production processes. Utility Model Content

[0005] Preferably, the upper surface of the cover is provided with a feed inlet on the side away from the air inlet, the feed inlet is connected to the inner cavity of the tank, the lower end of the tank is provided with a funnel section, the lower end of the funnel section is provided with a discharge port, and the discharge port is provided with a discharge valve.

[0006] Preferably, the power motor is fixedly connected to the mounting base by bolts, and the side wall of the mounting base has a through groove at the position corresponding to the air intake, through which the air intake passes through the side wall of the mounting base.

[0007] Preferably, a sealing gasket is provided between the upper end of the main air passage and the stirring shaft, and an opening is provided at the lower end of the main air passage and on the outside of the stirring shaft.

[0008] Preferably, the stirring frame is an L-shaped frame structure with a diagonal bar structure at the bend, and the upper outer end of the stirring frame extends to the outer side of the auxiliary air passage.

[0009] Compared with the prior art, the beneficial effects of this utility model are: replacing the traditional cooling air channel structure, by setting an air channel on the outside of the stirring shaft, while the rubber powder is stirred by the stirring frame, cooling air is introduced into the rubber powder through the air channel to cool the rubber powder. The distribution of cooling air is more uniform, thereby avoiding local overheating or clumping of rubber powder and avoiding the adverse effects of clumped rubber powder on subsequent production.
