Abstract

The invention discloses a digital intelligent liquid densitometer. The digital intelligent liquid densitometer comprises a PLC control system (1) and a density detecting system (2); the PLC control system (1) is used for controlling the density detecting system (2) to detect liquid density; the density detecting system (2) comprises a sampling pump (21), a primary automatic filter (23), a multistage sedimentation device (25), and a density detecting device (27) which are connected successively; the multistage sedimentation device (25) comprises at least two sedimentation units, wherein the volumes of the two sedimentation units are different, so that the flow speeds of a liquid to be detected through the two sedimentation units are different. The digital intelligent liquid densitometer is capable of realizing filtering sedimentation of impurities in the liquid to be detected, on one hand, influences caused by foam and crystals in the liquid to be detected are reduced, and on the other hand, static settlement is not needed, detection time is shortened, on-line real-time detection is realized, and influences on production caused by data delay are avoided.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a digital intelligent liquid density meter and a density detection method thereof. Background technique [0002] Qinghai is a resource-rich province with a wide variety of natural resources, among which the representative resources are salt lake resources, and the salt lake resources mainly include sedimentary resources and brine resources. Salt lake brine belongs to liquid chloride mineral resources and is rich in various components. Salt lake brine passes through The process of salt precipitation can produce sodium-containing carnallite, and further processing can produce potassium chloride to produce potassium fertilizer. There are many processes for producing potassium fertilizer by using salt lake brine. The reverse flotation cold crystallization process is a relatively advanced process in large-scale production. . [0003] In the flotation process, the required ...
