The paddle dryer is a low-speed stirring dryer with a stirring paddle inside the equipment, so that the wet material department can fully contact the heat carrier and the hot surface under the stirring of the paddle, so as to achieve the purpose of drying. The structure is generally horizontal, double-axis or four-axis. The paddle dryer is divided into hot air type and conduction type. The hot air type means that the heat carrier and the material to be dried are in contact with each other and dried. In the conduction type, the heat carrier does not directly contact the material to be dried, but the hot surface and the material are in contact with each other. The advantages of the conduction type are that the material is not easily polluted, the exhaust volume is small, the thermal efficiency is high, and the volume is relatively small, which is conducive to saving energy and preventing air pollution.
When the stirring blade in the paddle dryer is damaged, it will seriously affect the working efficiency of the dryer, because without the stirring blade, the sludge cannot be moved. .
In order to speed up the movement of the drying material to the outlet, some customers adjust the speed of the equipment to a very low speed, but the number of times the sludge material in the dryer is thrown out is reduced, the contact between the sludge material and the hot air is reduced, and the material will not be in the drum. Repeated back and forth, which means that the sludge passes through once, the sludge is quickly sent away, and the storage capacity of the material is too low, which reduces the working efficiency of the paddle dryer.
No matter which part is faulty, as long as the hollow paddle dryer fails, it will affect the work efficiency, so it is necessary to check and repair the dryer before and after work to ensure the normal use of the paddle dryer next time. Remember to troubleshoot and repair the fault, which is the basic condition to ensure the normal operation of the paddle dryer.
