In order to seal the dryer better, Huachang machinery after a number of R & D personnel, various studies and eventually a "labyrinth" seal device, and successfully applied slime bake dry machine, rotary dryer and tri Barrel dryer field.
The labyrinth seal of the dryer is to allow air to flow through the curved channel, creating fluid resistance and reducing the amount of air leakage. According to the direction of the labyrinth channel of the dryer, it is divided into an axial labyrinth seal and a radial labyrinth seal. The labyrinth seal structure of the slime dryer is simple and has no contact surface, so there is no wear problem and it is not affected by the turbulence of the barrel. Considering the manufacturing error, rigidity and bending of the cylinder axis of the cylinder body and the labyrinth seal itself, the gap between the adjacent labyrinth rings should not be too small, generally not less than 20-40 mm.

The slime itself has high humidity and high cohesiveness. During the drying process, the wet coal slime enters the coal slurry disintegration equipment via a belt conveyor, and after the fast-breaking massive coal slurry enters a dryer with a negative pressure, Four work areas: First, in the material guide zone, wet coal slime enters this area and rapidly evaporates a large amount of water after it comes into contact with high-temperature negative pressure hot air. The coal slurry is crushed by a large guide angle and is not bonded. The next working area is introduced. The second is the cleaning area where wet coal slime is copied by the copying board to form the material curtain state. When the material is dropped, it is easy to form a bonded drum wall. In this area, the equipment design includes a cleaning device and a cleaning device. The slime can be rapidly cleaned out of the wall of the binding cylinder. In this process, the cleaning device also acts as a crusher for the agglomeration of the mass ball, thereby increasing the heat exchange area, improving the efficiency of heat and mass transfer, and increasing the drying rate; The third is the inclined plate area, which is a low-temperature drying area. The slime has been in a state of low moisture looseness in this area. This area has no bonding phenomenon. After heat exchange, the finished product reaches the required moisture requirement, and the movement enters. The last out Region; Fourth discharge zone, this region of the drum drying machine does not copy board, rolling this material to the discharge opening region coasting, to complete the drying process.
