Calibration and impurity removing device for LPS (Laser Particle Spectrometer)

The invention discloses a calibration and impurity removing device for an LPS (Laser Particle Spectrometer), and the device comprises an installation support for installing the LPS, wherein the installation support comprises a first supporting rod for installing a laser emitter and a second supporting rod for installing a laser receiver; a motor support which is disposed between the first and second supporting rods and used for supporting a rotary motor; the rotary motor which is disposed on the motor support and has a known rotating speed; a connecting rod which is perpendicular to an output shaft of the rotary motor, wherein the central part of the connecting rod is connected with the output shaft of the rotary motor; and a first sphere which is at least disposed at one end of the connecting rod and has a known diameter, wherein the first sphere passes through a light band of the laser emitter. The device can achieve the calibration of the LPS through the combination of a simple mechanical structure and sim
