[0017] The present utility model will be further described below in conjunction with the drawings and embodiments.
[0018] Embodiment 1:
[0019] As Figure 1 shown, a continuous drying device for producing potassium dihydrogen phosphate includes a blower 1, a heater 2 and a vibrating dryer 3 connected in sequence through a pipeline (not marked); a vacuum feeding machine 4 is provided above the vibrating dryer 3, a feeding port (not marked) is provided in the middle of the vacuum feeding machine 4, and a vacuum port (not marked) is provided at the top; the discharge port of the vacuum feeding machine 4 is connected to one side of the top of the vibrating dryer 3, the air inlet pipe from the heater 2 is connected to the center, and the other side is connected to a cyclone separator 5; a vibrating motor 6 is provided at the bottom of the vibrating dryer 3, a material outlet (not marked) is provided on one side of the bottom of the vibrating dryer 3, the material outlet is connected to the feeding auger 7 through a pipeline, and the feeding port of the feeding auger 7 is also connected to the powder outlet of the cyclone separator 5; the air outlet of the cyclone separator 5 is connected to the induced draft fan 8.
[0020] During actual production, the blower 1 and the induced draft fan 8 are turned on. The hot air is heated by the heater 2 and then transported into the bottom of the vibrating dryer 3. The hot air rises along the vibrating cyclone disk (not marked) and enters the cyclone separator 5, and finally is drawn into the tail gas treatment device (not marked) by the induced draft fan 8. The potassium dihydrogen phosphate material to be dried is sucked into the vibrating dryer 3 by the vacuum loader 4. The material slowly flows downwards along the vibrating cyclone disk under the vibration of the vibrating motor, and fully contacts with the hot air for drying. When it flows to the bottom of the vibrating dryer 3, it will be completely dried. The dried qualified material is sent to the conveying auger 7 through the material outlet of the vibrating dryer 3. The conveying auger 7 simultaneously receives the fine powder material collected from the cyclone separator 5; and sends these materials to the packaging device for packaging at the same time.
