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.

A cuvette is fixedly arranged on one side of the bottom end of the support rod, a photoelectric detector is fixedly arranged on the inner wall of the cuvette, a stepping motor is fixedly arranged on one side of the inner wall of the detection support, a sheet wheel support is fixedly arranged at the bottom end of the stepping motor, and a plurality of optical filters with different wavelengths are fixedly arranged on the surface of the sheet wheel support; the LED light source is matched with the collimating lens group, divergent light is efficiently integrated into parallel light beams, it is ensured that the light is stably irradiated to a sample in the cuvette, a plurality of optical filters with different wavelengths are arranged on the sheet wheel support, the stepping motor drives the sheet wheel support to rotate, the optical filters with different wavelengths can be continuously clamped between the cuvette and the collimating lens group, and therefore the sample can be accurately detected. And the chromaticity detection of the sample under multiple wavelengths is realized.

This utility model relates to the field of circuit testing technology, and in particular to an integrated circuit testing device with stable positioning. It includes a circuit testing platform, a rotating stage at the top center of the platform, and several circuit testing racks at the top of the rotating stage. Integrated circuit boards are housed inside each testing rack. Several auxiliary lights are located on the top of the testing platform, outside the circumference of the rotating stage. This utility model's integrated circuit testing device with stable positioning provides stable support through the design of a circuit board placement frame and a positioning device, ensuring the stability of the integrated circuit board's position during testing, preventing displacement, and avoiding testing errors or damage caused by board loosening. Simultaneously, the cooperation of a transmission rod and a rotating knob allows the user to easily adjust the angle of the circuit testing racks, enabling testing personnel to flexibly adjust the angle of the integrated circuit board as needed.
