This invention relates to the field of silica moisture detection technology and discloses a near-infrared light-based silica moisture detection device for silica production. The device includes a feed pipe installed below a material rotary valve, a sight glass pipe mounted on the surface of the feed pipe, and a high-borosilicate tempered glass plate mounted on the sight glass pipe. An installation rod, a detection mechanism, and a remote display mechanism are provided on one side of the feed pipe. The detection mechanism is equipped with an installation adjustment mechanism for mounting the detection mechanism on the installation rod. The invention uses the installation adjustment mechanism to mount the detection mechanism on the installation rod and adjust it to a specific angle, aligning it with the high-borosilicate tempered glass. The light source in the detection mechanism emits specific near-infrared light, which is filtered by a rotating wheel and a reflector and then irradiated onto the silica material. Part of the near-infrared light is absorbed by the silica, while the remaining near-infrared light is scattered and focused into the near-infrared sensor by a concave mirror. The device is then connected to the remote display mechanism and a DCS system to perform the detection operation.
