The invention relates to the technical field of white
carbon black moisture detection, and discloses a near-
infrared light-based
moisture detection device for white
carbon black production, which comprises a blanking
pipe mounted below a material
rotary valve, a
sight glass pipeline is mounted on the surface of the blanking
pipe, high borosilicate tempered glass is mounted on the
sight glass pipeline, and a near-
infrared light source is mounted on the high borosilicate tempered glass. A mounting rod, a detection mechanism and a remote transmission display mechanism are arranged on one side of the discharging
pipe, and a mounting adjusting mechanism is arranged on the detection mechanism and used for mounting the detection mechanism on the mounting rod. A
light source in the detection mechanism emits specific near-
infrared light, the specific near-infrared light is irradiated on a white
carbon black material through a light filtering rotating wheel and a reflecting mirror, part of the near-infrared light is absorbed by white carbon black, the other part of the near-infrared light is scattered and then gathered into a near-infrared sensor through a concave mirror, and the near-infrared light is matched with a remote transmission display mechanism to be connected with a DCS (
Distributed Control System), so that the detection operation is realized.
