I. Electroplating sludge hollow blade dryer - equipment overview

The electroplating sludge hollow blade dryer is provided with a jacket on the dryer cylinder, a hollow blade is arranged on the hollow shaft, and a heat carrier is introduced into the jacket and the hollow blade to make the wet material under the agitation of the hollow blade Adequate heat exchange with the jacket and the hot surface of the hollow blade to achieve drying.

The hollow blade dryer comprises a casing jacket, the casing jacket has a W-shaped section, the end of the casing jacket is provided with an end cover, the upper cover of the casing jacket is provided with an upper cover, and the end cover is provided with two The hollow hollow mixing shaft has two hollow stirring shafts respectively located in two grooves of the W-shaped, two hollow stirring shafts are connected by gears, one of the hollow stirring shafts is connected with the speed reducer through a gear, and the speed reducer is connected with the electric motor; The hollow agitating shaft is provided with a hollow blade, the top end of the upper cover is provided with a steam outlet, the left end of the upper cover is provided with a feeding port, the right end of the casing clip is provided with a discharging port, and the end of the hollow stirring shaft is provided with a rotary joint .

The outer surface of the housing jacket, the end cover and the upper cover of the rotary joint is provided with an insulating layer. When in use, the heat medium flows through the casing jacket and the hollow agitating shaft and the hollow blade through the rotary joint. The heat medium is water vapor, heat transfer oil, hot water, cooling water, etc., and the heat of the heat medium is used to heat the material. The rotation of the hollow blade causes the material to be turned over and stirred, so that the material is fully in contact with the hollow blade, so that the material is heated sufficiently to evaporate the moisture on the surface of the material, and at the same time, the material is conveyed in the direction of the discharge port with the rotation of the hollow blade. Stirring is continued during transport to allow the water oozing out of the material to continue to evaporate. Finally, the uniformly qualified product is discharged from the discharge port.
