Embodiment Construction

[0013] In practical applications, a set of testing equipment is generally composed of two sets of measuring devices, so that the equidistant pressure drop signal of the anode guide rod can be measured. The installation distance of the two sets of measuring devices is determined according to the actual process and the installation position on the tank. It can be installed on the anodized aluminum bus bar or the support of the small joint fixture. The measuring wires (high temperature resistance) can be connected to the input terminal of the slot control machine in groups through the cable protection sleeve for signal transmission and data processing.

[0014] The conical contact (1) of the present invention is a signal detection element, which is mainly responsible for contacting the metal aluminum surface of the anode guide rod and returning the measured voltage signal. The use of a tapered structure can make the contact point contact, so as to improve the measurement accuracy,...

Abstract

The invention discloses an on-line detecting device of anode current, which comprises the following parts: conical contact, position adjusting spring, locating sleeve and stand, wherein the conical contact is loaded in the locating sleeve with rear connecting position adjusting spring; the locating sleeve connects the front end of screw sleeve; the stand connects the position adjusting spring and back end of screw sleeve; the back end of stand possesses connector lug; the stand and screw sleeve connect angle-bar rack through flannel and insulating pad.

Description

Technical field: [0001] The invention relates to an on-line continuous detection device for the anode current distribution of an aluminum electrolytic cell. Background technique: [0002] For a long time, the online continuous detection of the process parameters of the aluminum electrolytic cell has been the bottleneck that has plagued the greater development of the aluminum electrolytic process equipment technology and automatic control technology, especially the detection of the anode current distribution belongs to the electrolytic series. Every day in the daily production operation of each cell This is especially true for process parameters that need to be measured every shift. [0003] For many years, the anode current distribution measurement of domestic and foreign aluminum electrolytic cells has been measured by the backward method of manually using equidistant pressure drop measuring rods every day and every shift, which is time-consuming and labor-intensive, which ...
