FLAKERS FOR PA, MA, AND OTHERS

---

The function of water-cooled flakers is to convert the liquid material into irregularly scaled material through cooling crystallization, forming solid flakes in the drum. This process facilitates the storage, transportation, and downstream use of the phthalic anhydride, maleic anhydride, and other chemicals.

The flaker is an integral machine with all parts assembled on a sturdy chassis, and therefore, it can be simply used on a reinforced concrete foundation with toe bolts fastened. The flaker is fully enclosed. The input of liquid material, the flaking process, the discharge

of the sublimation material, and the output of the flaky solid are fully enclosed in the cover and the pipe without any exposure to the air. In this way, the air quality at the production plant is effectively controlled.

As a key part of the flaker, the water-cooled drum is mounted on a rolling bearing on both ends. The planetary cycloid reducer and the gear pair decelerate the motor, and the roller shaft is driven smoothly and slowly, and its speed is adjustable.

Cooling water goes into the hollow shaft of the drum through one end and exits through the other end. A beaded thread tray containing the heated liquid material is provided at the bottom of the tray. A liquid level controlling device is provided outside the drum to keep the liquid level of the tray constant. The bottom and sides of the tray are insulated jackets accessible to heating medium (water or steam) so that the temperature of the liquid tray is constant. The sheet-like solid material is scraped off the surface of the drum by a scraper that comprises a main blade shaft, main blades, and side blades. The blades are at an angle to the drum axis. The scraped material is discharged from the underneath outlet on the side, typically connected with an automated packing machine.
