Online sampling detection device for superfine heavy calcium carbonate powder production

Abstract

The invention discloses an online sampling detection device for superfine heavy calcium carbonate powder production. The online sampling detection device comprises a detection table, and a sampling mechanism, a dispersing mechanism and a detection mechanism arranged at the upper end of the detection table, wherein the lower end of the sampling mechanism is provided with a supporting frame I fixedly mounted at the left upper end of the detection table, and a sampler is fixedly mounted at the upper end of the supporting frame I. The online sampling detection device comprises the detection table,and the sampling mechanism, the dispersing mechanism and the detection mechanism arranged at the upper end of the detection table, so that the structure is relatively simple, the manufacturing cost is low, and the production cost is reduced; the detection distance of the whole device and the flexibility of sampling detection are improved through a sampling pipe set and a traction arm; and througha vibration core and a pressurization hole which are arranged in a disperser, the jet flow pressure and the jet flow activity in the whole jet flow hole are improved, calcium carbonate particles in the jet flow hole can be more uniformly dispersed, more uniform and stable aerosol can be formed at an outlet of the jet flow hole, and the measurement precision is improved.

Description

technical field [0001] The invention relates to the technical field of calcium carbonate production, in particular to an on-line sampling and detection device for the production of superfine heavy calcium carbonate powder. Background technique [0002] Heavy calcium carbonate refers to high-whiteness calcium carbonate powder with a particle size between 400-2500 mesh. It mainly has high whiteness, uniform particle size, and is odorless, tasteless, non-corrosive, non-radiative, and environmentally friendly. Conditions and other characteristics, due to the good dispersion of heavy calcium itself, rubber and plastics, paper, food, medicine, polymer composite materials, daily chemicals and other industries are currently the best raw materials and filling materials for these industries, while superfine heavy calcium High-quality calcium carbonate is a ground calcium carbonate powder with finer particle size and higher activity. Compared with ordinary heavy calcium carbonate, its ...

AI Technical Summary

Problems solved by technology

[0003] 1. The production of the laser particle size analyzer in the prior art is relatively complicated and the cost is high, thus increasing the production cost of industrial production;

[0004] 2. The volume of the laser particle size analyzer in the prior art is large, the use is not flexible enough, and the range of activities in the detection space is small;

[0005] 3. During the use of the laser particle size analyzer in the prior art, because the calcium carbonate powder has a certain viscosity, the calcium carbonate powder sticks in the injection hole, so the uniformity of the particle size of the injection will be reduced, affecting Its test accuracy
