Ensure the ventilation volume of the sand dryer, grasp the temperature of the dryer at any time, and add fuel according to this to achieve energy-saving drying state. The ventilation of the sand dryer is mainly between the drying cylinder of the dryer and the hot blast stove. It can use natural wind or artificial wind, and then blow the air volume to the cylinder of the dryer. The key parts of the best-selling exhaust management are flip valve and flash valve. Good operation of these two parts can ensure smooth exhaust and good ventilation. First of all, we should learn to judge the good and bad ventilation situation by ourselves. We use a simple way, first of all, we wet our hands, and then reach out to the outlet, so that if after a while the water on the hand is evaporated, it means that the ventilation is good, otherwise the ventilation is not good, need to adjust. Of course, this is a simpler and more effective way to judge.

The adjustment of ventilation volume can be adjusted in the following ways:

1. Pay attention to the air leakage condition between the turning plate, especially the sealing situation of the bearing part. And prevent the tipping valve into the larger slag chunks, bricks, wire and other debris. Cause deep wind, even hinder discharge or stuck plate, can not be turned over.

2. Observe how much the tipping valve is discharging and the size of the discharging interval, whether it is compatible with the discharging speed of the sludge dryer. Tipping bucket neither too much material to affect the discharge. Do not store too little material vibration must be numerous.

3. Refuel the rotating shaft oil cup on time. Each class twist L ~2 times, silver rotation can be a buckle. For the flashing valve to observe whether the operation is flexible, whether the blanking is unobvious, the balance hammer position is appropriate, the triangle cone and the feeding pipe mouth contact is tight. The balance hammer can be adjusted appropriately according to the ash accumulation and cutting. The triangular cone is usually movably attached to a lever. In order to avoid flashing due to vibration and displacement, it can also be fixed on the lever after alignment of the cutting pipe mouth.
