Used stainless steel blade dryer processing

A blade type dryer is a low-speed stirring dryer that is equipped with a stirring slurry inside the equipment, so that the wet material is fully mixed with the heat carrier and hot surface under the stirring of the blades, thereby achieving the purpose of drying. The structural form is generally double axis or four axis. The blade dryer is divided into hot air type and conduction type.

Hot air drying is achieved through the interaction between a heat carrier (such as hot air) and a dry material, while in conductive drying, the heat carrier does not directly interact with the dry material, but rather the hot surface interacts with the material.

Wedge shaped hollow blades are densely arranged on the hollow shaft, and the heat medium flows through the blades through the hollow shaft. The heat transfer area within a unit effective volume is large, and the temperature of the heat medium ranges from -40 to 320 ° C. It can be water vapor or various types such as hot water, thermal oil, etc. Indirectly transferring heat without carrying air away heat, the heat is used to heat the material, and the heat loss is only through the heat dissipation through the insulation layer of the device. The wedge-shaped blade has a self-cleaning function for heat transfer. The relative movement between material particles and the wedge-shaped surface produces a scrubbing effect, which can wash away the attachments on the wedge-shaped surface. The clean heat transfer surface is maintained throughout the trial operation.

The blade dryer consists of two to four interlocked blade shafts, a W-shaped shell with a jacket, a machine base, and a transmission part. The entire drying of materials is carried out in a closed state, and organic volatile gases and odorous gases are sent to the exhaust gas treatment device in a closed atmosphere to avoid pollution.

Dry materials are continuously fed into the spiral feeder in a quantitative mannerdryerThe feeding port is located behind the material inlet, and the rotation of the blade is used to move the materialflip、stirContinuously updating the heating interface, the body and blades are fully heated to evaporate the surface moisture contained in the material. At the same time, the material is transported in a spiral trajectory along the blade shaft towards the discharge port, and continues to stir during transportation to evaporate the water seeping out of the sludge. The uniformly dried qualified product is discharged from the discharge port.
