The cause of failure of double cone vacuum dryer

1. Double cone rotary vacuum dryer, in the closed sandwich into the heat energy, heat through the inner shell to be dried material. The material is in a vacuum state, and the water on the surface of the material is saturated and evaporated due to the decrease of steam pressure, which is discharged and recovered by the vacuum pump in time. Under the power drive, the tank body rotates slowly to achieve the purpose of strengthening drying.

2. When the vacuum degree reaches the requirements of the double-cone rotary vacuum dryer, the vacuum valve should be closed first, and then the power supply of the vacuum pump should be closed. When the vacuum degree is less than the requirements of the double-cone rotary vacuum dryer, the vacuum valve and the power supply of the vacuum pump should be opened and the vacuum pump should be pumped again, so as to prolong the service life of the vacuum pump.

3. If the bleed valve rubber plug is difficult to rotate, it can be coated with appropriate grease lubrication.

4. Except for maintenance, do not disassemble the left box cover to avoid damaging the electrical control system.

5. The double-cone rotary vacuum dryer shall not dry and put easy, explosive and corrosive materials.

6. The phenomenon that the double-cone rotary vacuum dryer cannot be vacuumized after being used for many times should be solved by replacing the door seal or adjusting the protrusion distance of the door buckle on the box.

7. Keep the clean double-cone rotary vacuum dryer clean. If not used for a long time, the exposed electroplated parts are placed in the indoor of the double-cone rotary vacuum dryer to avoid moisture damage to electrical components.

The above points are an overview of some of the causes and solutions of the easy failure of the double cone vacuum dryer.
