During the use of the flash dryer, we may encounter the problem of poor material transportation. This not only affects production efficiency, but can also lead to equipment damage. To solve this problem, we have summarized the following key factors and corresponding solutions.
First of all, we need to pay attention to the problem of feeding. The cake-like material is prone to bridging above the spiral conveyor shaft, resulting in the idling of the conveyor shaft. In order to ensure a smooth feeding, we need to strictly control the diameter of the filter cake block entering the hopper to less than 10 cm. When the material causes the bridging phenomenon, measures should be taken to break it up in time so that the input can be carried out smoothly. In addition, it is necessary to check whether there are debris such as metal iron sheets or coarse long fibers between the spiral blades, and clean up in time if any abnormalities are found. At the same time, for the situation that the motor or parts do not rotate, check whether the power cord head or the coupling connection screw is off, and take corresponding measures to solve it.
Secondly, we also need to pay attention to the problem of discharge. Due to the strong adhesion properties of light and fine materials, there may be unsmoothness when the cone is discharged under the cyclone. At this time, we can gently tap the cone to make the material attached to the pipe wall fall smoothly after vibration. In order to ensure that the cyclone cone is not deformed when beating, we can add a reinforcing ring or a vibrating iron bar to the cone to improve the smoothness of discharge. At the same time, it is necessary to pay attention to controlling the amount of solids in the exhaust gas to be less than 2% to avoid the problem of running materials.
To sum up, poor material transportation can be caused by a variety of factors. By mastering the above solutions, we can effectively deal with various problems and ensure the stable operation and efficient production of flash dryers.
