Online detection device for the distribution uniformity of paper-making reconstituted tobacco pulp

The invention relates to an online detection device for the distribution uniformity of paper-making reconstituted tobacco pulp. The online detection device comprises a sampling system, a mixing, diluting and metering system and a measuring system, the sampling system comprises an automatic sampling device, and an inlet of the automatic sampling device is connected with an outlet pipeline of the last mill in the reconstituted tobacco pulping process; the mixing, diluting and metering system comprises a mixing dilution tank, a centrifugal pump, a buffer tank, an electromagnetic flowmeter and a pneumatic control valve; and the measuring system comprises a first measuring chamber, a second measuring chamber, a third measuring chamber, a fourth measuring chamber and a vacuum pump which have the same structure. According to the method, online detection of distribution of all components of the pulp in the paper-making reconstituted tobacco production process is achieved, data support is provided for pulp distributio
