Titanium dioxide hollow blade dryer
working principle
The titanium dioxide hollow blade dryer consists of two to four blade shafts engaged with each other, a W-shaped shell with a jacket, a base and a transmission part. The entire drying process of the material is carried out in a closed state. Organic volatile gases and odorous gases are sent to the exhaust gas treatment device in a closed atmosphere to avoid environmental pollution.
The dryer uses steam, hot water or heat transfer oil as the heating medium, and the shaft end is equipped with a rotary joint for introducing and discharging the heat medium. The heating medium is divided into two paths, which enter the jacket of the dryer shell and the inner cavity of the blade shaft respectively, heating the dryer body and the blade shaft at the same time, and heating and drying the material in a conductive heating method. The dried material is quantitatively and continuously fed into the feeding port of the dryer by the screw feeder. The material enters the back of the dryer. Through the rotation of the blades, the material is turned over and stirred. The heating interface is constantly updated, and it comes into contact with the body and blades. It is fully heated to evaporate the surface moisture contained in the material. At the same time, the material is transported in a spiral trajectory towards the discharge port with the rotation of the blade shaft, and continues to be stirred during the transportation, so that the water seeping out in the sludge continues to evaporate. Finally, the evenly dried qualified product is discharged from the discharge port.
equipment characteristics
1. The equipment structure is compact and the device covers a small area. It can be seen from the structure of the equipment that the heat required for drying is mainly provided by the wall surfaces of the hollow blades arranged on the hollow shaft, while the heat transfer capacity of the jacket wall only accounts for a small part. Therefore, the heat transfer area per unit volume of equipment is large, which can save the equipment floor area and reduce infrastructure investment.
2. High heat utilization rate. The sludge dryer uses conductive heating for heating, and all heat transfer surfaces are covered with materials, reducing heat loss; there is no hot air to carry away heat, and the heat utilization rate can reach more than 90%.
3. Wedge blades have self-purification ability, which can improve the heat transfer effect of the blades. The dispersing force generated by the combined movement of the inclined surface of the rotating blade and the particle or powder layer automatically removes the sludge attached to the heating slope, and the blade maintains an efficient heat transfer function. In addition, due to the reverse rotation of the two shaft blades and the stirring functions of alternating segmented compression (when the two shaft blade surfaces are closest to each other) and expansion (when the two shaft blade surfaces are farthest away), the heat transfer is uniform and the heat transfer is improved. effect.
