How to deal with sudden power failure of sludge dryer during operation
For the sludge dryer we are very familiar with, because now the country for environmental monitoring is very strict, so for the city clean and tidy people pay special attention to, and the emergence of sludge dryer to a certain extent eased this problem, so people are still very concerned about the sludge dryer, we all know that the drum dryer in the operation The drum is driven by the motor all the time, so what should we do if there is a sudden power failure during the operation of the sludge dryer?
The cylinder of the sludge dryer is rotary, and the staggered spiral plates are welded in the cylinder to roll the material. Sludge is a kind of material with high viscosity and high humidity. In order to fully dry, the conveying system first sends it into the dispersing device during the drying process, and the device can quickly disperse it, so that the material becomes sludge of uniform size, which is conducive to better drying.
When the sludge dryer is in operation, it not only needs fuel to generate heat, but also needs the motor to drive the drum to rotate and dry. No matter what machinery is cut off suddenly, it will do great harm to it, let alone the sludge dryer. First of all, the operator needs to stop feeding in time, reduce the amount of fuel, and correspondingly reduce the rotation speed of the dryer drum, so as to prevent the materials that have not been dried from rushing to the discharge end of the drum, so as to prevent the excessive temperature difference of the dryer drum. If the temperature difference of the drum is too large, the drum will be deformed.
In case of sudden power failure or unexpected power failure of the sludge dryer, the staff should first test the temperature of the dryer cylinder to see if the temperature of the cylinder is above 80C. If the temperature of the cylinder of the drum is above 80 ℃, the staff should drive the drive belt of the dryer manually for 20 minutes, The equipment can rotate freely, and the drum temperature of the direct dryer can wait for the cylinder to dry naturally until it is below 80 ℃. If you restart the machine, you need to wait for the power supply to be restored after the power maintenance.
