Drum dryers is the drying of materials commonly used equipment. Reliable operation of such equipment, operating flexibility, adaptability, and high processing capacity, are widely used in chemical industry, metallurgy, building materials, light industry and other sectors.
Drum dryer cylinder, bearing devices, fixed devices and end seals and other components.
The gear of the drum dryer; motor, reducer, gear, ring gear part out equipment, and sealing devices.
The cylinder drum dryer matrix, both in its internal heat transfer, mass transfer process was underway to move the conveyor material role. Cylinder bearing unit is by the rolling circle, wheel, gear wheel composed of three parts. Throughout the cylinder weight by rolling circle pass the roller, the rolling ring rolling in the supporting wheel, gear wheel from the block cylinder axial movement.
The working principle and structure characteristics and the production ofDrum dryerto maintain the experience of the drum dryer, drum dryer machinery and equipment to ensure long-term safe operation, the key is to adjust the supporting wheel.
Maintenance of the linear axis of the drum dryer; so that the cylinder along the axis normal to move back and forth, so that the gear wheels remain stationary turn or for a short period of time by the force of little movement, so that each gear wheel, roller evenly commitment cylinder load.
Steps / methods
Drum dryers riding wheel adjustment methods:
Observe the relative position of the tire and the occasional round is still in the gear wheel force and rotation in the middle position;
Supporting roller adjustment according to the direction of cylinder rotation, adjust the riding wheel centerline, taken in a certain direction at the same time skew roller, to form a slight angle (generally not more than 0.5 ° with the cylinder centerline, in order to avoid occasional round ground produce thrust upward spiral shaped), so channeling power and cylinder up and down the basic balance, simplified operation in a relatively stable position, which is round with in the next gear wheel between free reciprocating motion.
Adjustment procedure is as follows: Simplified move down the adjustment bolt tighten the circle, bolt sucking back around (note to twist tight laps and sucking back the number of turns equal), Simplified will stop down; if the anti- come to move up, and liquid lubricants on the occasional round, Simplified will stop the move, if it is still on the move, then tighten the bolts a, sucking back the bolt 2, simplified to stop the move; in turn down should be on supporting roller lubricating sleeve to wipe out, if necessary, repeat the aforementioned method, until ran so far. Adjustment process, to prevent the occasional round skewed to different directions.
In the adjustment process, in order to make the cylinder on the shift, the best in the surface of the supporting roller poured some lubricant, so as to increase the surface friction; contrary purports cylinder decline can be poured some thick grease to reduce the surface friction . Adjust the riding wheel to adjust the four wheel, and ensure that the wheel round with and care is not less than 50% of the contact surface.
