[0017] The working principle of the utility model is as follows: the moisture absorption device is installed above the sodium thiocyanate material storage line in the bin to prevent sodium thiocyanate with a lower particle size from entering the filter screen. Under normal storage conditions, the porous structure of the super absorbent resin has a stronger water absorption and water storage capacity than sodium thiocyanate. The moisture in the bin is adsorbed by the super absorbent resin to prevent the sodium thiocyanate from absorbing water and hardening. After the absorbent resin has been stored and used for a certain period of time, the water absorption capacity of the absorbent resin decreases. In order to continuously ensure high water absorption capacity, the first valve and the second valve are opened, and the electric heating wire, the motor and the exhaust fan are started. The electric heating wire is The highly absorbent resin is heated at a low temperature of 60°C, and the water vapor is evaporated and carried out of the bin body through high-speed airflow, so that the highly absorbent resin is regenerated and can be continuously recycled, saving costs; after the motor is started, it drives the auger blades to rotate, which can accelerate the heat transfer between the absorbent resins, especially when the outer diameter of the auger blades is half the diameter of the filter screen, the auger blades feed upward, and the highly absorbent resin close to the filter screen falls downward, forming a circulating feeding function from the middle to the surroundings, and at the same time, it is blown out from the middle of the filter screen with the external airflow, so that the heated resin flows in the same direction as the airflow, accelerating the water vapor to be carried out of the bin body.
