Sand dryer ventilation adjustment method

Date: 2019-07-17 Views:

Ensure the air volume of the sand dryer, at any time to grasp the temperature of the dryer, and according to the fuel added to achieve energy saving drying state.Sand dryer ventilation, mainly in the dryer drying drum and between the hot air stove, it can use natural wind, or artificial wind, and then the air into the dryer drum.

1.Check the sand dryer

The key parts of exhaust selling well are flap valve and flash valve. Only by operating these two parts well can we ensure the smooth exhaust and good ventilation.First of all, we should learn to judge the ventilation of good or bad.In this way, if the water on the hand is evaporated after a while, it means that the ventilation is good. Otherwise, the ventilation is not good and needs to be adjusted.Of course, this is a simpler and more effective way to judge.

2 .sand dryer ventilation adjustment


We can adjust the ventilation volume in the following ways:

1. Pay attention to the air leakage between the plates, especially the sealing of bearing parts.And prevent falling into the plate valve larger slag block, brick, wire and other sundries.Cause deep wind, or even prevent discharge or stuck plate, can not be flipped.

2. Observe the amount of blanking of the flap valve and the size of blanking interval, and whether it is suitable for the blanking speed of the sludge dryer.Do not store too much material in the hopper to affect the discharge.Don't save too little material for vibration.

3, on time to the shaft oil cup refueling.Each shift twist l~2 times, silver time rotation button can be.To the flash valve to observe whether the operation is flexible, whether the blanking is unobstructed, whether the position of the balance hammer is appropriate, whether the triangle cone and the blanking pipe mouth contact is tight.According to the ash blanking, the balance hammer can be adjusted appropriately.A triangular cone is usually attached to a lever.In order to avoid flicker displacement due to vibration, it can also be fixed and welded on the lever after aligning the feeding pipe mouth.
