FLAKERS FOR PA, MA, AND OTHERS

---

The function of water-cooled flakers is to convert the liquid material to the irregularly scaled material through the 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, and 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 motor is decelerated by the planetary cycloid reducer and the gear pair, 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 is provided at the bottom of the tray containing the heated liquid

material. 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 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 which is comprised of 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.
