DETAILED DESCRIPTION
[0020] The technical scheme of the utility model is further explained below in combination with the drawings and specific embodiments.
[0021] Embodiment one
[0022] AsFigures 1-4 As shown, the present invention proposes a spray drying powder forming device, comprising a spray drying device 1, a crushing box 2 is fixedly installed at the output end of the lower surface of the spray drying device 1, the dry material prepared in the spray drying device 1 falls into the crushing box 2, the lower surface of the crushing box 2 is fixedly connected to a funnel 5, the lower surface of the funnel 5 is fixedly connected to a material collecting box 3, a discharge port 4 is provided on one side of the outer surface of the material collecting box 3, and an inclined slope 13 is provided at the bottom of the inner wall of the material collecting box 3. The setting of the inclined slope 13 facilitates the powdered material collected in the material collecting box 3 to be discharged from the inner wall. The material is discharged from the material port 4, and a rotating shaft 10 is rotatably installed on the lower surface of the material collecting box 3. One end of the rotating shaft 10 located inside the crushing box 2 is fixedly connected to a centrifugal turntable 9, and a crushing liner 8 is fixedly installed inside the crushing box 2. A crushing blade 12 is fixedly installed on the outer surface of the rotating shaft 10, and the crushing blade 12 is located inside the crushing tube 6. A rotating motor 7 is fixedly installed on the lower surface of the material collecting box 3, and the end of the output shaft of the rotating motor 7 is fixedly connected to the end of the rotating shaft 10. The rotating motor 7 drives the rotating shaft 10 to rotate, thereby driving the centrifugal turntable 9 and the crushing blade 12 to rotate.
[0023] When the present invention is in use, the dry material produced inside the spray drying equipment 1 falls onto the centrifugal turntable 9 inside the crushing box 2, and the rotating shaft 10 drives the crushing blade 12 and the centrifugal turntable 9 to rotate. Then, the dry material on the centrifugal turntable 9 is scattered to all sides under the action of centrifugal force and hits the crushing liner 8. The particles in the dry material are broken during the collision. The broken dry material falls into the crushing tube 6, and the rotating crushing blade 12 crushes the dry material again, so that the dry material that has not been crushed is crushed into powder, and the powdered material falls into the material collecting box 3 and is discharged from the discharge port 4.
[0024] Example 2
[0025] like Figure 3 and Figure 4 As shown, the present invention proposes a spray drying powder-forming device. Compared with the first embodiment, this embodiment further includes a conical guide block 14 fixedly installed at the axial position of the upper surface of the centrifugal turntable 9. When the material inside the spray drying equipment 1 falls on the centrifugal turntable 9, it is dispersed to the surroundings under the action of the conical guide block 14, thereby facilitating the material on the centrifugal turntable 9 to be dispersed to the surroundings under the action of centrifugal force. An extended guide ring 11 is provided on the inner wall of the funnel 5 near the lower surface, and the inner diameter of the extended guide ring 11 is smaller than the pulverizing tube 6.
[0026] In this embodiment, the extended guide ring 11 guides the material sliding down the inner wall of the funnel 5, preventing the material from sliding down the inner wall of the crushing tube 6 and being unable to contact the crushing blade 12, thereby improving the crushing efficiency of the crushing blade 12 for the material.
[0027] The above specific embodiments are only several preferred embodiments of the present application, and based on the technical scheme of the present application and the related enlightenment of the above embodiments, the person skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
