Online slurry densimeter and measuring method thereof

Abstract

The invention provides an online slurry densimeter and a measurement method thereof. The online slurry densimeter comprises a bracket, a first pipeline, a second pipeline, a middle pipeline, two flexible connecting sections and a deformation detection unit, the support is fixedly arranged on the ground, and the interior of the support is hollow. The first pipeline and the second pipeline are used for conveying slurry of which the density is to be measured, and the first pipeline and the second pipeline are horizontally arranged at an interval; the middle pipeline is horizontally arranged above the bracket between the first pipeline and the second pipeline; the two flexible connecting sections are arranged at the two ends of the middle pipeline in the axial extending direction correspondingly and communicate the middle pipeline with the first pipeline or the second pipeline correspondingly. The deformation detection unit comprises a laser emitting part, a laser receiving part and a light reflecting part which are arranged in the bracket; the laser emitting part emits laser to the surface of the light reflecting part, the laser irradiates the surface of the laser receiving part to form light spots after being reflected, and the density of the slurry in the middle pipeline is indirectly calculated in a non-contact mode according to position changes of the light spots.

Description

Technical field [0001] The present invention relates to the field of slurry density detecting equipment, and more particularly to a linear slide density meter and its measurement method. Background technique [0002] In industrial and agricultural production, it is often involved in the measurement of the density of the slurry. In the existing technique, based on the dry weighing direct measurement method, in fact, the time is poor, and cannot be satisfied with the quick adjustment of the parameters of intelligent manufacturing. Based on the density meter based on radiation source technology, due to the increasing attention of environmental health. Faced with the phase-out; the online measurement technology based on ultrasonic waves is limited in the particle size limit of the slurry; chromatographic imaging techniques, etc., also difficult to have a large amount of prevention due to insufficient measurement accuracy. In summary, there is currently an urgent need for reliable, co...

Problems solved by technology

In the existing technology, the direct measurement method based on dry weighing has poor real-time performance and cannot meet the requirements of rapid adjustment of parameters in the field of intelligent manufacturing; the density meter based on radioactive source technology is being gradually Facing the situation of being eliminated; the ultrasonic-based online measurement technology is limited by the size of the particles in the slurry; tomographic imaging technology is also difficult to popularize and apply in large areas due to insufficient measurement accuracy and high price
