Common faults and treatment of fluidised bed dryer

Fluidised bed dryer common faults and ways to deal with them

Material from the inlet into the machine, under the action of vibration force, the material along the horizontal surface of the fluidised bed throw, forward continuous movement, hot air upward through the fluidised bed with the wet material heat exchange, wet air by the cyclone separator dust removal by the exhaust air 1:3 discharge. The dry material is discharged from the discharge inlet. In the work of the material often run off the problem, but also due to the vibration motor in the installation of the two motors vibration angle of deviation caused by the equipment to facilitate troubleshooting and maintenance of equipment, we should do what preventive measures?

    1. The equipment should be installed on a solid and horizontal concrete floor or floor, and according to the design drawings were pre-embedded fixed fluidised bed host, cyclone separator, fan, dust collector and other supporting components.
    2. Connect the pipelines between the host, cyclone separator, fan and dust collector according to the installation drawings, and connect the steam pipeline while adopting steam heating.
    3 vibrating fluidised bed with the vibration motor should be the same level of the angle of adjustment of the host on both sides of the eccentric block, adjust the requirements should be achieved at both ends of the host vibration oscillation force is the same, the host shall not appear forward or backward string or to the left, to the right and back and forth swing, the eccentric block should be equipped with a safety guard.
    4. Each component pipe connection, its flange two planes should be parallel, the degree of non-parallelism shall not be greater than 2mm, the connection should be lined with seals, the diameter of the fixing screws shall not be small instead of large, the connection of its flange misalignment shall not be more than 2mm.
    5. After connecting the pipelines of each component, it should be checked carefully to make sure that there is no mistake, it should be ventilated for gas sealing inspection respectively, and steam should be used as the heat source for steam sealing inspection, and the phenomenon of air leakage or gas leakage should be adopted immediately for encrypting measures.
    6. Check the fasteners fixed firmness.
    7. The machine electrical control cabinet should be placed in a convenient location to operate, and to ensure safety. In the electrical control cabinet site around, there shall be no flammable, explosive gas or other flammable, explosive substances. The machine parts and electrical control system should have good protection grounding connection and grounding device, and the device has a conspicuous marking.
    8. The dryer is qualified by the airtightness inspection, and should carry out the idling test for not less than 30 minutes.
