Ensure that the amount of ventilation of the sand dryer, keep track of the temperature inside the dryer, and accordingly the addition of fuel in order to achieve energy-saving drying state. Sand dryer ventilation, mainly in the dryer drying cylinder and hot air furnace between, it can use natural wind, but also can be artificial wind, and then the amount of wind blowing to the dryer's cylinder. The key parts to manage the exhaust air selling are the flap valve and flashing valve, operate these 2 parts well to ensure the exhaust air smoothly and well ventilated. First of all, we have to learn to judge the good and bad ventilation situation by ourselves. We use the simpler way, first of all, we wet our hands, and then extend the hand to the outlet, in this case, if after a while on the hands of the water is evaporated, it shows that the ventilation is good, and vice versa that the ventilation does not work, need to be adjusted. Of course, this is only the simpler and more effective way to determine.

Adjustment of ventilation we can be debugged in the following way:

1, we should pay attention to the flap between the leakage of the wind Qian situation, especially the bearing parts of the sealing situation. And prevent the flap valve fall in big more slag chunks, bricks, wire and other debris. Caused by deep wind, and even impede the discharge or stuck flap, can not be flipped.

2, observe the flap valve under the material more or less and under the material interval size, whether with the sludge dryer discharge speed compatible. Do not store too much material in the hopper to affect the discharge. And do not store too little material vibration shall be prosperous.

3, to the rotor shaft oil cup refueling on time. Screwed l ~ 2 times per shift, silver rotating a buckle can be. On the flash valve to observe whether the operation is flexible, whether the material is smooth, balance hammer position is appropriate, triangular cone and the material pipe mouth contact is tight.

According to the accumulation of ash under the material situation, you can adjust the balance hammer appropriate. The triangular cone is usually movably connected to the lever. In order to avoid flickering due to vibration and displacement, can also be aligned with the mouth of the downstream material pipe after it is fixed welded on the lever.
