Embodiment 1

[0027] In this preferred embodiment, two spray guns 5-1 and 5-2 are provided. In addition, a spray drying chamber 4 is set between the trapping chamber 2 and the boiling fluidized granulation chamber 9, and the top of the trapping chamber 2 is provided with a shaking bag cylinder 1 and a trapping bag 3, and a centrifugal fan 13 is connected to the upper part. The bottom of the boiling fluidized granulation chamber 9 is provided with an air flow distribution plate 10 , and the lower part is provided with an air supply chamber 11 and a regulating valve 14 . The spray gun is located at the junction of the spray drying chamber 4 and the boiling fluidized granulation chamber 9 .

[0028] Such as figure 1 with figure 2 As shown, in this embodiment, spray gun brackets 7-1 and 7-2 arranged vertically and vertically at a stepless adjustment plate 8 installed in the tank body of the spray drying chamber, spray guns 5-1 and 5 -2 are installed on the spray gun brackets 7-1 and 7-2 res...

Embodiment 2

[0031] Such as figure 1 with Figure 4 As shown, in this embodiment, the spray gun brackets 7-1 and 7-2 arranged vertically up and down in sequence are arranged at the stepless adjustment plate 8 installed in the tank body of the spray drying chamber, and the spray guns 5-1 and 5-2 Installed on spray gun brackets 7-1 and 7-2 respectively, the two spray guns 5-1 and 5-2 are in different horizontal planes and vertical planes. The positions of the two spray guns 5-1 and 5-2 can be adjusted along the longitudinal axis of the granulator with the stepless adjustment plate. Preferably, the included angle θ of the two spray guns in the horizontal plane is 45°, the linear distance between the spray heads 6-1 and 6-2 in the horizontal projection plane is 550mm, and the shortest distance h between the spray heads and the inner wall of the tank is 400mm (see Figure 4 ). All the other structures are the same as in Embodiment 1.

Embodiment 3

[0033] In this example, if Figure 5 As shown, the two spray guns 5-1 and 5-2 are respectively installed on two stepless adjustment plates 8-1 and 8-2 on the same horizontal horizontal axis of the granulator, and the stepless adjustment plate 8-1 is located at 8 Opposite side of -2. The positions of the two spray guns 5-1 and 5-2 can be adjusted along the longitudinal axis of the granulator with the stepless adjustment plate. Preferably, the linear distance between the nozzles 6-1 and 6-2 of the spray gun is 600mm, and the shortest distance h between the two nozzles and the inner wall of the tank is 400mm. More preferably, the distance between the stepless adjustment plates 8-1 and 8-2 is equal. All the other structures are the same as in Embodiment 1.

Abstract

The fluidizing and spray drying pelletizer includes a pelletizer tank, boiling and fluidizing palletizing chamber, spray drying chamber over the boiling and fluidizing palletizing chamber, and spraying guns set between the spray drying chamber and the boiling and fluidizing palletizing chamber. The spraying guns have installation positions and angles adjustable so as to avoid the superposing of the atomizing angles of the guns and avoid contact of atomized material to the inner wall of the pelletizer tank. The fluidizing and spray drying pelletizer has increased material liquid atomizing range, shortened operation period, lowered production cost, raised production efficiency and saving in power.

Description

technical field [0001] The invention relates to a fluidized spray drying granulator, especially a granulator suitable for the production of granular products in the pharmaceutical, food and chemical industries. Background technique [0002] In the existing technology, the PGL series spray drying granulator developed by Chongqing Guangsha Drying Equipment Engineering Co., Ltd. is a granulation equipment integrating mixing, spraying, drying, granulation, granule coating and other functions. Because the granulation equipment can directly make the material liquid into uniform, soluble, and fluid granules in one step, it has become a granulation equipment widely used in pharmaceutical, food, chemical and other industries, especially suitable for the production of traditional Chinese medicine liquid extracts. Dry and granulate. In the existing granulator tank, there is only one spray gun for atomizing the feed liquid, which limits the feeding amount of the feed liquid and seed po...
