Sand dryers are large-scale industrial equipment designed for rapid removal of moisture from sand. They use a multi-layer rotary cylinder structure and use hot air as a heat source for indirect or direct heat exchange, so that wet sand is heated evenly in a continuous tumbling state, thereby effectively dehydrating. It is characterized by large processing capacity, high drying efficiency, and stable operation. It is widely used in construction, sand and gravel aggregates, glass and other industries, and plays an important role in improving sand quality and meeting subsequent processing needs.
1. Detection and repair of blade reversal in sand dryers.
Observe or use the equipment monitoring system to determine whether the direction of blade rotation is abnormal. If blade reversal is found, first stop the machine to check the drive system, confirm whether the motor wiring is correct, whether there is an electrical fault or the inverter setting is wrong. If the hardware is correct, there may be a problem in the mechanical transmission link, such as reverse installation of transmission parts such as chains and gears. At this time, the corresponding parts need to be disassembled and reassembled.
2. Detection and repair of damage to the heating pipe of the sand dryer.
If the drying efficiency is reduced or the local temperature is abnormal during operation, it may be because the heating pipe is damaged. Turn off the power, wait for the equipment to cool down, open the dryer and check the internal heating elements to see if there are any breaks, corrosion or serious dust accumulation. Replace the damaged heating tube and clean the attachments to ensure that the new heating element is in good contact with the heat-conducting part. Turn on the machine for testing after it is safe and reliable.
3. How to repair the leakage of the sand dryer cylinder?
When the cylinder leaks, first determine the leak location. If it is caused by cracks or holes in the cylinder weld, it can be repaired by welding. If necessary, a pressure test is required to verify the repair effect. For leaks caused by severe deformation of the cylinder, it may be necessary to adjust the cylinder or even replace the damaged part.
