Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stirring devices, in particular to a stirring device for a flash drying machine. Background Art
[0002] Flash dryer is a new type of continuous drying equipment integrating drying, crushing and screening. It is particularly suitable for drying filter cake, paste and slurry materials. The drying time of wet materials in the drying tower is only 5-8 seconds, and the water evaporates instantly. The quality of the dried product is closely related to the drying temperature, wind speed, air volume and crushing speed. The hot air enters the annular gap at the bottom of the drying chamber from the inlet pipe in a tangential direction and rises in a spiral shape. At the same time, the material is quantitatively added into the tower by the feeder and fully heat-exchanged with the hot air. The larger and wetter materials are mechanically crushed by the agitator, and the materials with lower moisture content and smaller particle size rise together with the rotating airflow and are transported to the separator for gas-solid separation. The finished products are collected and packaged, and the tail gas is discharged after being treated by the dust removal device.
[0003] Conventional stirring devices on the existing market are of straight and figure-eight structures. However, when encountering certain materials that are prone to caking, the stirring blade is easily deformed due to uneven force, and the rotational dynamic balance is even destroyed after a period of use. When the agglomerated materials enter the feeding chamber of the flash main engine, they are not completely broken up, the stirring situation in the flash dryer cannot be observed, the flash dryer cannot be internally inspected, and the stirring blade cannot be replaced. Therefore, we need to propose a stirring device for the flash dryer. Utility Model Content
