What to do before working on a dehydrated vegetable belt dryer

The dryer uses a variety of relatively good raw materials, which depends mainly on the performance of the article. At the same time, when designing and installing, testing in the laboratory is based on a series of parameters, and then determining the appropriate treatment, while at the same time working. Need to make all kinds of preparations.

Dehydrated vegetable belt dryer preparation:

1. Check the joints of the bearing and sealing parts of each device for looseness, the condition of the lubricating oil of each mechanical component and whether the water, wind and slurry valve ports are in the required position. Then turn on the power to check whether the voltage and the meter are normal. After the Zui, check the amount and concentration of the slurry in the slurry mixing tank. If there is any problem, it should be eliminated in time.

2, because the dryer is more frequently applied to dry fabrics, tobacco leaves, surface coatings of substrates and other flaky materials, etc., considering that it usually consists of two conveyor belts, and needs to be separated into units Independent control. Therefore, after the voltage and instrument inspection are completed, it is also necessary to clean and clean the two conveyor belts of the dryer.

3. Then turn on the blower and exhaust fan in turn, then turn on the heating switch to start heating up. When the outlet temperature reaches the set temperature (generally around 130 °C), start the material pump and dust removal system. When the pump pressure reached 2 MPa, drying began.

Pay attention to the observation of the ammeter when the fan of the dehydrated vegetable belt dryer starts. When the fan current is stabilized, start the second unit. It is strictly forbidden to start all the fans without changing the ammeter. The purpose of this is to avoid excessive current, and to observe whether there is a fan that does not work. Thirdly, the current of each motor can be observed to facilitate the determination of motor failure.
