Abstract

The invention discloses an online liquidity detection and control system for lyosol products. The online liquidity detection and control system comprises an industrial personal computer and a liquidity detection module, the flowability detection module is used for sampling and detecting the first flowing-out part of the product; the industrial control computer is used for immediately correcting process parameters of each device in the production process according to a detection result of the fluidity detection module, controlling a valve of a production pipeline, and transferring unqualified products before the correction moment to a waste tank; the fluidity detection module comprises a turntable, a liquid pipe and a liquid level sensor; when the turntable rotates, the liquid in the liquid pipe is centrifuged. And the speed information is obtained by calculating the time difference of the liquid between the two sensors. The speed information is compared with an empirical value. In a production line, specific numerical value indexes reflecting the fluidity do not need to be known, and only the speed information of qualified products under the same condition is used. For different types of products, corresponding empirical values are adopted for comparison. Through the detection and control system, the number of unqualified products can be controlled within a very small range.

Description

Technical field [0001] The present invention is created to be an application of computer control technology in production control, specifically a liquid sol product flow online monitoring system. Background [0002] Most liquid sol products, its fluidity is a necessary testing item, and its testing is mostly detected by flow detectors in the laboratory. In the large-scale production of flow-through production, the sampling and testing of batch production products is determined to determine whether the popularity of batch products is qualified. The main problem is that if the test is unqualified, the entire batch of products is not qualified. [0003] Through the retrospective of the production process of nonconforming products, it is found that the main reason for the non-conformity is the deviation of process parameters, and there is generally no deviation if the controllability of the feeding amount is better. If the flow information is obtained online in advance during the pr...
