Filtering control system

Abstract

The invention relates to the technical field of filtering, and discloses a filtering control system. The filtering control system comprises a filtering system, a washing system connected with the filtering system, and an air-blowing system connected with the filtering system; the filtering system comprises a filtering device; an inlet of the filtering device is connected with a raw liquid inlet section, and an outlet of the filtering device is connected with a filter liquid outlet section; the washing system comprises a washing liquid inlet section connected with the inlet and / or the outlet ofthe filtering device; the air-blowing system comprises an air exhausting section arranged on the filtering device and a blowback air inlet section connected with the filter liquid outlet section; control valves are connected with the raw liquid unlet section, the filtered liquid outlet section, the washing liquid inlet section, the air exhausting section and the blowback air inlet section. The filtering control device is high in automation degree, reduces labor intensity of operators, and saves operation time. The nickel electrolysis system is bad in environment, a medium has corrosivity, sothat by adopting the filtering control system, it is avoided that due to the fact that an operator directly makes contact with the corrosive medium, the body is injured, and the operation environmentis improved; in addition, manual misoperation can be avoided.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a filtration control system. Background technique [0002] In the production process of electro-nickel, the purity of the electrolyte directly affects the product quality of electro-nickel. The electrolyte produced by the electrolysis process usually contains harmful impurities such as lead, copper, cobalt, and iron. These impurities enter the system, which will reduce the quality of nickel during electrolysis, which in turn will reduce the purity of electrolytic nickel. Therefore, these impurities must be removed before the electrolyte enters the electrolytic cell to ensure the product quality of electrolytic nickel. [0003] In the prior art, solid-liquid separation equipment (filter) is usually used in the nickel electrolysis workshop of the nickel smelter, which has great fluctuations in the stability of the electrolytic nickel production quality in terms of production, ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the nickel electrolysis workshop of the nickel smelter usually uses solid-liquid separation equipment (filter), which has a large fluctuation in the stability of the electrolytic nickel production quality in terms of production, overhaul, maintenance, and testing.

Moreover, with the increase in the production capacity of the nickel electrolysis workshop, the demand for new solution gradually increases, the raw material is unstable, the amount of impurities increases, and the depth of impurity removal in the purification process increases, resulting in fluctuations in production and unstable control

Moreover, in the maintenance of the filter, manual operation is required to repair and maintain each filter, resulting in a large workload for the post personnel and low labor production efficiency, which cannot meet the needs of large-scale development of modern enterprises.
