AI Technical Summary

Technical Problem

Existing spray granulation equipment fails to effectively utilize the waste heat of hot air during use, resulting in energy waste, and the practicality and feasibility of the equipment need to be improved.

Method used

A spray granulation device was designed, comprising a hot air chamber and a processing chamber in a drying box. The raw material is dried by a hot air blower, and the exhaust gas enters the jacket of the storage tank through a transfer pipe for preheating. The waste heat of the exhaust gas is used to preheat the storage tank, and the stirring effect is enhanced by the design of the stirring blades.

Benefits of technology

It improves the utilization rate of exhaust gas, increases the practicality and feasibility of the equipment, reduces energy waste, and enhances the overall performance of the equipment.

Abstract

The invention discloses spray granulation equipment and a spray granulation method, and relates to the technical field of spray granulation. The device comprises a drying box, the drying box internally comprises a hot air cavity and a processing cavity, an air heater is installed in the hot air cavity, a filter plate is installed between the hot air cavity and the processing cavity, and a discharging opening is formed in the processing cavity; and the storage tank is provided with a discharging pipe communicating with the processing cavity, and a stirring piece is installed in the storage tank. When the device is used, air is blown into the processing cavity through the air heater, raw materials are dried through hot air, particles formed by the raw materials can be discharged through a discharging port, and the blown-out hot air moves in the processing cavity, gradually moves into a transfer pipe and enters an interlayer of a storage tank through the transfer pipe; and the storage tank is preheated through waste heat of tail gas, the utilization rate of the tail gas is increased, and then the practicability of the device is improved.
