A rotary dryer for producing sodium 5-sulfoisophthalate

Abstract

The utility model relates to drying -machine technical field especially relates to a rotating disc formula drying -machine for isophthalic acid - 5 - sodium production, including bottom plate and drying cylinder, two symmetrical fixed plate of fixed installation are installed on the bottom plate, the rotating shaft of hollow structure is rotatably installed between two fixed plates, and the rotating shaft is fixedly installed in the drying cylinder, a plurality of gas outlets are arranged on the rotating shaft, and a plurality of equidistance setting stirring rods for stirring the material in the drying cylinder are fixedly installed on the rotating shaft. The utility model discloses through the reverse rotation of drying cylinder and rotating shaft, isophthalic acid - 5 - sodium in the drying cylinder is fully turned over, makes phthalic acid - 5 - sodium and hot steam fully mix, improves product drying quality, speeds up drying rate, and the filter screen on the gas outlet is cleaned with the cooperation of cleaning brush, and high-pressure air is delivered to the rotating shaft with the cooperation of the delivery pump, and the particles on the filter screen are removed, preventing the filter screen from being blocked and affecting the hot steam flow rate.
