AI Technical Summary

Technical Problem

The existing process directly feeds the granulated material into a belt dryer for high-temperature drying after granulation, which easily leads to uneven moisture distribution among the particles, causing particle breakage and affecting the performance of the composite catalytic combustion aid.

Method used

The device employs a preheating and drying unit. By setting up a preheating chamber with a frame and a support box, it achieves uniform spreading of materials and mobile covering and removal of moisture. Combined with electric push rods and suction cylinders, it ensures that the materials are uniformly preheated and treated with moisture before entering the drying unit.

Benefits of technology

It improves the preparation effect of composite catalytic combustion aid, reduces equipment operating costs, reduces the labor intensity of operators, prevents damage to the conveyor belt, and improves preheating efficiency and water vapor treatment efficiency.
