Abstract

The invention relates to a liquid state concentration trace change measuring device and a measuring method thereof. The liquid concentration trace change measuring device is characterized in that a plurality of liquid level detection probes are arranged on an upper side wall of a flow stabilization cylinder, a liquid level floating ball is arranged in an inner cavity of the flow stabilization cylinder, a centre shaft through hole is formed in the liquid level floating ball to pass through a buoy rod, an upper end of the buoy rod passes through a top cover of the flow stabilization cylinder tobe connected with a concentration scaleplate, and a lower end face of the buoy rod is connected with a hollow buoy to form a buoyancy type indicating structure; the weight of the hollow buoy is proportional to the volume of the hollow buoy, the buoy rod is slidably connected with the centre shaft through hole in the flow stabilization cylinder to form a free ascending or descending sliding connection structure, so as to drive the trace ascending or descending of the concentration scaleplate to maintain that the liquid level floating ball always flows on the liquid level of a liquid state, anda liquid state concentration trace change measuring structure is formed. By adoption of the buoyancy principle, in the case of a trace change in the liquid density, the change amount of the liquid density is detected through the height change of the buoy rod. The liquid state concentration trace change measuring device has the advantages that the trace change in the nitrate concentration is measured easily, the product quality is ensured, the production efficiency is high, and so on.

Description

technical field [0001] The invention relates to a device for measuring trace changes in liquid concentration and a measuring method thereof, which is a method for detecting liquid density changes through height changes of buoys. It belongs to the technical field of liquid detection equipment. Background technique [0002] At present, in the metal heat treatment industry, if nitrate quenching is used, it can obtain smaller deformation than oil quenching, so that the workpiece has better mechanical properties and has the characteristics of reducing environmental pollution. However, due to the slow cooling rate of anhydrous nitrate, the use of nitrate in metal heat treatment is limited. The latest research and production practices have found that if a certain amount of water is added to nitrate, the cooling of nitrate can be achieved. The speed is greatly improved, adding different water content, it has different cooling speed. However, in the prior art, there is no special c...
