Precise filter device

Abstract

The invention relates to the technical field of filtering, and discloses a precise filter device. The precise filter device comprises a flow collecting tube and a vertical barrel; a gland is detachably connected to the upper portion of the barrel, and a sewage discharging connecting tube is connected to the bottom of the barrel; a liquid inlet connecting tube is further connected to the barrel; multiple filtering components are fixedly connected to the gland, the lower end of each filtering component is inserted into the barrel, the upper end of each filtering component extends out the gland and is connected with a tube branch, and the tube branches are connected to flow collecting tube separately. The precise filter device is provided with the filtering components with an adsorbing function, and has advantages that filtering precision is high, a beta value is high, and the quantity of received pollutants is large; solid particle impurities and other suspending substances in electrolyte (Ni2SO4) can be effectively removed, the certain effect of removing oil and organic matter is also realized, and secondary pollution to a stock solution is not generated.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a precision filter. 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, the solid-liquid separation equipment usually used in the nickel electrolysis workshop of the nickel smelter is mainly a tubular filter, which has certain gaps and deficiencies compared with other equipment of the same kind in terms of product...

Problems solved by technology

[0003] In the prior art, the solid-liquid separation equipment usually used in the nickel electrolysis workshop of the nickel smelter is mainly a tubular filter, which has certain gaps and deficiencies compared with other equipment of the same kind in terms of production, overhaul, maintenance, and testing. Especially for the stability of the quality of electro-nickel production fluctuates greatly

Moreover, with the increase in the production capacity of the nickel electrolysis workshop, t
