Optimization of the routine maintenance of the fluid bed dryer works
Fluid bed dryer is a dryer, also known as fluidized bed, usually by the heater, the host of the fluidized bed, cyclone, bag filter, induced draft fan, console composition. The fluid bed dryer is the use of air heated by the heat exchanger, the formation of hot air through the valve plate assigned to enter the host, the wet material from the feeder into the dryer, the role of wind pressure, the material in the boiling state within the dryer and hot air extensive contacts, resulting in a shorter time to complete the drying materials.
  Boiling drying equipment, the basic principle of the fluidized bed work based on its material basis of the drying process is boiling powders.
  In the exhaust under the fine powder within the container trap bag filter back row to the outside, the trapping process there are a large number of ultra-fine powder to produce, whether it is boiling in the flow or trap run the whole process of boiling dry with ultra-fine powder movement.
  However, the process of powder movement is often accompanied by two problems with static electricity and dust explosion under the guidance of some of the factors to cause an explosion phenomenon. Therefore particularly important for the daily maintenance and regular maintenance of the fluid bed dryer, summarized as follows:
  A day-to-day maintenance
  1, the operator first checks before each operation the steam valve, compressed air and the range table is normal.
  2, check under the airbag ring with raised, flat head screws are tightened to prevent the expected car is pushed crashed.
  Check the hopper blade turbine is too tight, bladed paddle too tight and resistance of the material, resulting in the increase in stirring motor drive load, so that the transmission bumps break or motor burned.
  4, check under the pressure of the airbag ring 0.1 ~ 0.15mpa pressure is too high is easy to cause the seal burst is too low will not achieve the sealing effect powder leakage to affect the production efficiency and drying quality.
  5, check the compressed air pressure is too high:
  6, likely to cause hot and cold damper cylinder momentum Ambassador throttle live then break or damage to the sealant, the drying effect of the leak impact.
  7, the bag rack cylinder thrust is too large, the putter is easy to bend.
  Second, regular maintenance
  On a regular basis in efficiency filter bags monthly cleaning time from boiling machine outlet into the loose framework of screws, remove the mesh bag first with detergent and soak for 30 minutes, then rinse with water, dried.
  Add oil, regularly cleaning the mixing device in the transmission.
  3, regularly skip the drive gear lubricating, fill in the records of equipment lubrication.
