Description

Technical Field

[0001] The present application relates to the technical field of cement production detection, and in particular to a cement particle size measuring device. Background Art

[0002] The particle size of cement is the dispersion of cement, that is, the coarseness and fineness of cement particles. The sieve residue percentage refers to the percentage of the sieve residue mass of cement on a sieve with a certain aperture to the total mass of cement. The finer the cement particles, the larger the specific surface area. The mass percentage of particles of different particle sizes in cement can reflect the true fineness of cement. It is very necessary to measure the particle gradation of cement to improve the grinding efficiency and improve the quality of cement.

[0003] In the patent document with the published announcement number CN205749201U, an online cement particle size detection device with improved measurement effect is provided. The online cement particle size detection device with improved measurement effect is provided with a process main pipe, a sampler, a cement sample flow pool, a particle size detector, a cyclone dust collector, a cement disperser, an air pipe, a valve plate, a baffle, an air hole, a slide groove, and a slide handle. By adding a signal isolator between the signal control box and the laser particle size analyzer, the mutual interference between the power supply signal and the control signal of the laser particle size analyzer can be effectively eliminated to ensure the accuracy of the measurement result; the air pipe with optimized structural design can conveniently and instantly adjust the air flow size used to blow away the cement, so as to blow the cement into single particles, thereby improving the test effect of the cement.

[0004] However, after research and analysis, it was found that the online cement particle size detection device improves the testing effect of cement by setting up a process main pipe, a sampler, a cement sample flow pool, a particle size detector, a cyclone dust collector, a cement disperser, an air pipe, a valve plate, a baffle and other components to control the airflow size. However, after the external airflow enters the pipeline, the pipeline is relatively narrow, which increases the wind pressure, making it difficult to control the airflow speed in the pipeline, and it is impossible to blow the cement into a single particle state for detection, which is not convenient for the detection of cement particles. At the same time, the cement accumulates during detection and is difficult to disperse, affecting the detection effect. Utility Model Content
