Device for measuring liquid level of flotation pulp

Abstract

The invention belongs to the technical field of flotation liquid level measurement, in particular to a device for measuring the liquid level of flotation pulp. The device comprises a separation barrel, a measuring floater and a laser distance measuring sensor, wherein the measuring floater is arranged in the separation barrel, and the laser distance measuring sensor is arranged above the axial center line of the separation barrel. The device is characterized by further comprising a flushing water nozzle which is arranged on the top of the separation barrel, the measuring floater comprises a connecting rod, a reflecting disc, a balance disc, two limiting blocks, a balance weight cone and a floating ball, wherein the reflecting disc is arranged on the top of the connecting rod, the balance disc is arranged on the lower portion of the reflecting disc, the two limiting blocks are arranged at the bottom of the connecting rod, the balance weight cone is arranged at the bottom end of the connecting rod, and the floating ball is arranged between the two limiting blocks and connected with the connecting rod in a sliding mode. By the adoption of the novel measuring floater, the floating ball is prevented from being affected by the perpendicular fluctuation and the horizontal fluctuation of the pulp in the separation barrel, tangential flushing water is arranged on the top of the separation barrel, therefore, dynamical frictional resistance is reduced, the defoaming effect is achieved, measuring errors are small, and the liquid level of the pulp is stably and accurately measured.

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...

AI Technical Summary

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
