Problems solved by technology
After the vibrating fluidized bed drying system has been in operation for a period of time, since the distribution plate of the fluidized bed includes sieve plate, screen mesh and sintered orifice plate, material leakage is easy to occur during operation. If adding a filter mesh will increase the system resistance, Affect drying effect
The core equipment of the vibrating fluidized bed drying system is the vibrating fluidized bed dryer, whose vibration source is a vibration motor, and the equipment is noisy in operation
The vibrating parts are easily damaged, the system operation period is short, and the maintenance is frequent

Embodiment 1
[0040] like figure 1 Shown, the ammonium sulfate solution (this system is about 22.9 cubic meters per hour to the treatment capacity of ammonium sulfate solution) of the ammonium sulfate solution (this system is about 22.9 cubic meters per hour) of solid content 15% and above that the external system of the present invention transports enters cyclone 1 at first and carries out preliminary solid-liquid separation , the separated ammonium sulfate supernatant enters the feed liquid tank for recovery, and the separated dense phase ammonium sulfate solution enters the vacuum belt filter 2 for suction filtration. The clear liquid after suction filtration by the vacuum belt filter 2 enters the feed liquid tank for recovery, and the ammonium sulfate solid filter cake enters the flash dryer 6 for drying treatment. The blower 4 blows air into the hot air heater 5 for heating, and heats the hot air to about 150°C. The outlet of the hot air heater 5 is directly connected to the flash drye...
