Abstract

The invention discloses an automatic electrode replacing device of an online heavy metal analyzer. The automatic electrode replacing device is characterized in that an electric control precise translation platform and an electric control precise rotary platform are adopted to provide power for lifting and rotating of an electrode selecting disc, a feeler lever, a feeler lever fixing platform, the electrode selecting disc and a plurality of electrode contacts with the same quantity as electrodes form an electrode signal leading-out device, and when the electric control precise rotary platform drives the electrode selecting disc to rotate, and the electrode contacts are jointed with the feeler lever one by one so as to lead out signals of the electrodes correspondingly connected with the electrode contacts. The automatic electrode replacing device is applied to the online heavy metal analyzer, working electrodes can be rapidly replaced, the single duration performance of an instrument is prolonged, and long-time unattended operation is realized.

Description

technical field [0001] The invention belongs to the technical field of electrochemical detection, in particular to an automatic electrode replacement device for an online heavy metal analyzer. Background technique [0002] The existing electrochemical workstations produced by Metrohm in Switzerland and the electrochemical workstations produced by China Chenhua generally use clamps to hold the metal ends of the electrodes, and then lead them out through the wires on the clamps. The signal of the electrode is sent to the electrochemical workstation, and this process is generally completed by manual operation. This method of relying on manual operation makes the following problems exist when the electrochemical test method is introduced into the online analysis instrument: [0003] 1. It is impossible to realize the automatic operation of the instrument by manually replacing the electrodes. [0004] 2. When testing multiple samples, the electrode is replaced manually, which i...
