Abstract

The invention discloses a device for analyzing the interface of a double-float ball red mud setting tank, comprising: a setting tank, a hoisting mechanism and a cable length measuring device. Two sets of pulley sets (1) with measuring scale racks controlled by a PLC control system are arranged on the setting tank (3); the hoisting mechanism and the cable length measuring device (2) are respectively connected with a large float ball (4) and a small float ball (5) in the setting tank (3) through the cables; the large float ball (4) and the small float ball (5) have different volume and identical density; the shells of the large float ball (4) and the small float ball (5) are made of stainless steel with lead sands filled therein; and the cables connected with the float balls are made of a material with high temperature resistance (greater than 100 DEG C), alkali / acid corrosion resistance and small ductility. The invention solves the problem that the sensitivity of the measuring detector is directly influenced as the measuring detector is easy to have scars in the prior art; the device has the advantages of reliable measurement, investment conservation and low cost; and the maintenance time and the labor intensity are reduced.

Description

technical field [0001] The invention relates to a red mud settling tank interface analysis device for alumina production. Background technique [0002] During the red mud separation and sedimentation process of alumina production, the liquid material in the red mud settling tank is divided into a clear liquid layer, an intermediate layer, and a red mud layer from top to bottom through separation and sedimentation. The production process needs to measure the density of these three layers of materials, the height of the middle layer and the red mud layer. At present, most domestic measurement systems adopt the ultrasonic principle, such as figure 1 As shown, the system usually consists of the following parts: ultrasonic density measuring probe, cable connecting the measuring probe, hoisting mechanism, cable length measuring device and PLC control system. The working principle of the system is: the PLC control system controls the winch mechanism and the cable length measuring...
