It is not convenient to remove moisture and reduces the drying effect. Therefore, we propose a drying treatment device for super dry reagent production to solve the above problems.

When the tank is full, the placement plate and two sliders are pushed backward into two guide rails, and then the door is closed. The drive motor drives the rotation of the drive shaft and the semi-circular gear. Because the semi-circular gear and the two racks are alternately meshed, the semi-circular gear drives the frame and the rack to move back and forth. The rack drives the drive gear and the rotating shaft to rotate in opposite directions. The rotating shaft drives the heating rod to swing back and forth. Through the back-and-forth swinging heating rod, the ultra-dry reagent in the placement tank can be heated and dried evenly and comprehensively.

[0016] In this invention, a drying device for producing ultra-dry reagents is described. An air pump draws residual heat from the drying chamber into a connecting pipe and a serpentine heat exchange tube. The S-shaped serpentine heat exchange tube allows for full contact with the air in the heat exchange chamber, absorbing heat and heating the air. This avoids direct heat loss, making it more energy-efficient. The heated air is then drawn into the air inlet pipe and drying chamber by an air pump to blow hot air onto the ultra-dry reagents, further improving drying efficiency. The heat from the serpentine heat exchange tube is absorbed by the air in the chamber, causing the hot air to cool and condense, then drain from the drain pipe, effectively removing water vapor and achieving dehumidification. This prevents excessive water vapor in the drying chamber from reducing the drying effect.

[0017] This utility model has a reasonable structural design. The placement mechanism facilitates the handling of ultra-dry reagents, and the swing heating mechanism not only heats and dries the ultra-dry reagents evenly and comprehensively, but also facilitates the connection of the heating rod to an external power source, improving the efficiency of use. It can not only recycle heat and avoid the waste of heat by direct heat discharge, but also discharge water vapor to achieve a dehumidification effect, avoiding the presence of too much water vapor in the drying chamber, which would reduce the drying effect.
