Specific embodiment
The invention will be further described below.Following examples are only used for the technical side for clearly illustrating the present invention
Case, and can not be limited the scope of the invention with this.
As shown in figure 1, the close type circulation spray drying system tracer method granule density measuring system of the present invention, including laser
Light source 4, aluminium powder colloid, image collecting device 5, solvent fluid and spray drying system.
Specifically, spray drying system includes scroll casing type hot air distributor 2, nebulizer 3, material liquid import 1, hothouse 8,
Carrying object loop exit 6 and material outlet 7.Hothouse 8 is the chamber of a closing, and top is cylinder, and bottom is cone, circle
Heat transfer medium circuit outlet 6 is set on the bottom chamber locular wall of cylinder, the bottom opening of cone is material outlet 7.The top of cylinder
Central authorities open up material liquid import 1.Scroll casing type hot air distributor 2 is installed on the top of hothouse, and positioned at material liquid import 1 just
Top, for importing carrying object and carrying object flowing being changed into rotary wind.Nebulizer 3 is located at the top position inside hothouse.
Aluminium powder colloid is mixed to form material liquid with solvent fluid, is delivered to nebulizer 3 via material liquid import 1.
Further, LASER Light Source 4 is arc light source, positioned at the side of hothouse 8, diameter of the width for hothouse 8, figure
As harvester 5 is located at the opposite side of hothouse 8, the right opposite of arc light source.
As shown in Fig. 2 LASER Light Source has three groups of 4-1,4-2,4-3, corresponding configuration three image collecting device 5-1,5-
2,5-3, LASER Light Source and image collecting device are adjacent two-by-two to be evenly distributed on around hothouse 8, it is ensured that every group of laser light
Source just to an image collecting device, from comprehensive analysis granule density on three directions.
Preferably, the light that LASER Light Source sends is directional light, reflexes to other image acquisition to reduce light Jing aluminium powders surface
Phenomenon on device.It is that pure white surface is used to receive the laser that transmission comes that image collecting device receives laser side.
