Description

Technical Field

[0001] The utility model relates to the technical field of optical detection applications, in particular to a solid material screening spectrum detection device. Background Art

[0002] Near-infrared spectroscopy analysis technology is a rapidly developing analytical method with a rapidly expanding application field. It has the technical advantages of being non-destructive, rapid, multi-index real-time detection and control, and green and environmentally friendly. It is very suitable for the composition analysis of industrial products and is applicable to the detection of various sample states such as solids, liquids, gases, suspensions, pastes, etc.

[0003] The effectiveness of near-infrared instrumentation depends on ensuring effective collection of optical signals. Applying online detection technology in industrial production processes requires effectively combining near-infrared instrumentation with engineering modifications to on-site detection points to form a complete and reliable online detection system. Suitable sample flow devices are required for materials in different states. To a certain extent, in the field of online analysis, the adaptability of the flow device determines the level of detection accuracy that can be achieved, which is also a key application difficulty that distinguishes it from offline detection.

[0004] For solid materials with uneven particle sizes, such as corn gluten meal and germ meal, non-contact, large-spot, diffuse reflectance spectral signal acquisition methods are ideal. For materials transported in pipelines, ensuring optical detection accuracy and representativeness requires certain requirements for particle size uniformity. When measuring materials through an optical inspection window mounted on an inclined chute, the material must be as uniform as possible, with a uniform flow rate and a certain accumulation thickness. Existing inclined chutes lack this structure, significantly impacting measurement results. Utility Model Content

A counterweight pressure plate is hinged between the upper ends of the two converging baffles. A converging inclined plate is provided at the upper end of each converging baffle, and the two converging inclined plates are in an inverted eight shape.

[0023] The inclined chute pipeline 1 includes an inclined pipe 101 arranged in the middle and tilted downward. The upper end of the inclined pipe 101 is connected to an upper vertical pipe 102 and the lower end is connected to a lower vertical pipe 103.

[0024] A sampling port 10 is provided at the lower portion of the top plate of the inclined pipe 101 .

[0025] An inspection port is provided on the upper portion of the top plate of the inclined pipe 101 and an upper cover plate 11 is installed at the inspection port for daily maintenance of the chute device.

[0026] The ends of the upper vertical pipe 102 and the lower vertical pipe 103 are both provided with connecting flanges 12 .

[0027] A viewing window is provided at the bottom of the bottom plate of the inclined pipe 101 and a viewing window 2 is installed in the viewing window. A near-infrared spectrometer 3 is vertically provided below the viewing window 2.

[0031] The screen plate 7 is extended upward to the side wall of the upper vertical pipe 102 and is welded thereto, so as to screen and separate the large and small particles of the solid material flowing into the pipe.

[0032] The herringbone dividing plate 8 is used to guide the material flowing through the upper side of the screen plate 7 to both sides, so as to prevent the screened material from directly hitting the window 2 and protect the window 2.
