Abstract

The invention discloses a chemical analysis data online detection method in a cement production process, which adopts a continuous flow sampling technology and a continuous flow sampling technology torealize field detection in the cement production process, and comprises the following steps of respectively weighing 1.0-3.0 g of samples, respectively putting the samples into 150 ml beakers, adding25 ml-35 ml of water, and stirring to completely disperse the samples, accurately adding hydrochloric acid by using a burette under stirring, carrying out online real-time detection, accurately detecting the contents of insoluble substances, gelled silicon dioxide and sulfur trioxide in the cement product and other components in the raw materials, and adjusting corresponding parameters in real time according to the detection result, thereby implementing effective control on the cement production process. Links of sampling, inspection and the like are omitted, so that the cement production quality can be mastered timely, quickly and accurately; aiming at the problem of abnormal quality, the production process can be adjusted in time, the production process is improved, the production costis reduced, and the cement product quality is improved.

Description

technical field [0001] The invention relates to the technical field of cement production detection, in particular to an online detection method for chemical analysis data in the cement production process. Background technique [0002] As the country vigorously strengthens infrastructure construction, cement is an indispensable material for infrastructure construction, and its product quality is increasingly valued by the market. Cement production has the characteristics of large-scale and continuous production, and is a typical process-based production. At present, most cement production enterprises use off-line quality inspection in terms of production quality control, that is, a combination of regular sampling and laboratory testing, and use fluorescence analyzers and particle size detectors for production process quality inspection. This kind of production quality control method has the following disadvantages: 1. Some products cannot be sampled on site, and there are fe...
