In-vessel layered interface measurement device and method

Abstract

The invention relates to an in-vessel layered interface measurement device and method. The device comprises a vessel, a constant temperature guide tube, a temperature detection module and a control module; the vessel is used for containing solid and liquid or stratified liquid; the constant temperature guide tube is located inside the vessel or outside the vessel, the arrangement direction of the constant temperature guide tube is in the height direction of the vessel, the height of the constant temperature guide tube is at least the same as that of the solid and liquid or the stratified liquid which is contained in the vessel, and the constant temperature guide tube is used for releasing heat to the solid and liquid or the stratified liquid which is contained in the vessel; the temperature detection module is located on the outer wall of the vessel and comprises multiple temperature detection points which are arranged in the height direction of the vessel and used for detecting temperature signals and transmitting the temperature signals to the control module, and the distances between the temperature detection points and the constant temperature guide tube are the same; the control module is used for receiving the temperature of the constant temperature guide tube and the temperature signals of the temperature detection module and outputting densities corresponding to all the temperature detection point positions, and layered interfaces are obtained according to the densities. According to the in-vessel layered interface measurement device and method, real-time non-contact measurement can be conducted, and the measurement result is precise.

Description

technical field [0001] The invention relates to the technical field of solid-liquid layering or liquid-liquid layering interface measurement, in particular to a device and method for measuring layered interface in a container. Background technique [0002] The solid liquid or liquid that can be stratified in the container will appear stratified after standing for a long time. It has always been a difficult problem to measure the thickness and interface of solid-liquid and liquid-liquid layers with different densities. The existing measurement method is generally to manually hang the probe from the upper opening of the container, and measure according to the different buoyancy of the liquid with different densities during the hanging process, but this method cannot perform real-time measurement. In addition, when the probe touches a solid, it cannot be measured. This method is also limited by the measurement medium and is not suitable for the measurement of solids. Content...
