Problems solved by technology

In the actual application process, the fluctuation of the liquid level in the flotation machine causes the floating ball to be unstable. At the same time, the flotation foam adheres to the surface of the floating ball, which hinders the free movement of the floating ball and affects the measurement accuracy of the laser sensor. The system liquid level value is distorted and cannot be effectively controlled

Abstract

The invention belongs to the technical field of flotation liquid level measurement, and in particular relates to a liquid level measurement device for flotation pulp, which includes an isolation cylinder, and a measuring float arranged in the isolation cylinder is arranged in the axial center of the isolation cylinder The laser distance measuring sensor above the line is characterized in that it also includes a flushing water nozzle arranged on the top of the isolation cylinder, the measuring float includes a connecting rod, a reflective disk arranged on the top of the connecting rod, and a reflective disk arranged at the bottom of the reflective disk. The balance plate, the two limit stoppers arranged at the bottom of the connecting rod, the counterweight cone arranged at the bottom end of the connecting rod, the floating ball arranged between the two limit stoppers, and the floating ball is slidably connected with the connecting rod. The invention adopts a new type of measuring float, which avoids the influence of the floating ball on the vertical and horizontal fluctuations of the pulp in the isolation cylinder. The top of the isolation cylinder is provided with tangential flushing water, which reduces the dynamic friction resistance and plays the role of defoaming. The measurement error is small and the realization of Stable and accurate measurement of the slurry level.

Description

technical field [0001] The invention belongs to the technical field of flotation liquid level measurement, in particular to a liquid level measurement device for flotation pulp. Background technique [0002] Flotation is a technical method for separating useful minerals from ores according to the different physical and chemical properties of the surface of mineral particles. It is widely used in the separation of fine-grained and ultra-fine-grained materials. A flotation machine is a mechanical device that completes the flotation process. In the flotation machine, the pulp treated with chemicals is agitated and aerated, so that some of the ore particles are selectively fixed on the air bubbles, float to the surface of the pulp and are scraped off to form foam products, and the rest remain in the pulp. In order to achieve the purpose of separating minerals. During the flotation process, due to changes in the properties of the pulp, flow fluctuations and other factors, the p...
