Tank entering and exiting system and method

Abstract

The invention discloses a tank entering and exiting system. A cart girder which can be shifted is arranged above electrolytic tanks arranged to form an array, and a circular track is arranged on the cart girder. The circular track is movably provided with a plurality of liftable mechanical arms, and a feeding and discharging area a, a tank area b to be entered, a tank entering and exiting workingarea c and a discharging passivation area d are arranged on the circular track and on the side of the circular track. The mechanical arms move along the circular track to work, N electrolytic tanks are arranged in a row, and the whole system is provided with N+1 mechanical arms and a positioning device. The first mechanical arm entering the system is only responsible for removing a negative plate,the last mechanical arm is only responsible for inserting the negative plate, and all the mechanical arms in the middle complete two jobs of the insertion of a tank position negative plate and the extraction of the next tank position negative plate, namely all the mechanical arms working twice in one working period. Compared with the previous process that each mechanical arm only works once in one working period, the working efficiency is significantly improved.

Description

technical field [0001] The invention relates to the technical field of automatic production of electrolytic manganese, in particular to a system and method for entering and exiting a cathode plate in a manganese electrolytic cell. Background technique [0002] The production process of electrolytic manganese can be divided into three parts: liquid preparation, electrolysis and finished product treatment, specifically: leaching, oxidation and iron removal, neutralization, solid-liquid separation, vulcanization and heavy metal removal, electrolysis, stripping, crushing, rinsing and deacidification , drying and metering packaging. Generally, 18 hours after the start of the electrolysis reaction, the manganese content on the cathode plate can reach 96%. In order to match the day and night working hours, the current electrolysis time is generally set at 24 hours. After the electrolysis, the cathode plate full of manganese needs to be taken out of the electrolytic cell, so the re...
