The invention discloses an analysis meter for multiple factors of frictional electrification of grains, which comprises a sealed transparent container, a feeding device, an air inlet valve, an air outlet valve, an electronic scale, a support platform, a fan, a faraday cage and an electrometer, wherein the support platform is arranged in the sealed transparent container; the feeding device is in shaft connection with the support platform; the fan and the electronic scale are fixedly arranged on the support platform; the faraday cage is arranged on the electronic scale; the electrometer is electrically connected to the faraday cage; and the air inlet valve and the air outlet valve are respectively fixedly arranged on two side walls of the sealed transparent container. The frictional electrification is measured in the sealed transparent container, so as to specifically measure the influences of outside influencing factors on the frictional electrification. A wire net is glued to the inner wall of the sealed transparent container, so as to preferably separate the electric field in the sealed transparent container from the outside, thereby preventing the influence of an outside electric field on the measurement.
Description
technical field [0001] The invention relates to the field of measuring instruments, in particular to a multi-factor analyzer for particle frictional charge. Background technique [0002] Friction electrification is a common electrification phenomenon in daily life, but there has been no clear conclusion on the influencing factors of friction electrification. The current measuring instruments cannot measure the influencing factors of triboelectricity, especially the influencing factors of triboelectric electrification of the same material. . [0003] To sum up, in the process of realizing the present invention, the inventor found that there are at least the following defects in the prior art: [0004] (1) It is not possible to clearly measure the influence of various factors in the process of triboelectrification on triboelectrification. Contents of the invention [0005] The purpose of the present invention is to solve the above problems and propose a multi-factor analyz...
