Abstract

The utility model relates to a mixer, which is mainly used for removing calcium and magnesium through chemical precipitation during nickel sulfate precipitation in a wet method. The mixer comprises a reactor, a mixing shaft and a plurality of mixing blades fixed on the mixing shaft, and is characterized in that the mixing blades are arranged on three layers. The lower surfaces of the mixing blades on the upper layer generally adopt a plane, the upper surfaces of the mixing blades on the middle layer adopt a multi-faceted geometric structure, and the upper surfaces of the mixing blades on the lower layer adopt a V shape. The mixing blades on the upper layer press down mixture solution, so that the solution can be fully mixed with upturning solution for reaction; the mixing blades on the middle layer can push the solution in an upturning way for mixing, so that turbulence of solution can be formed on different layers and a precipitant can be fully mixed with the solution; and the mixing blades on the lower layer can make the unspent precipitant fully mixed with the solution at the conical bottom of the calcium/magnesium removal reactor, pipeline blockage caused by the deposition of reactants can be avoided effectively, and the efficiency of calcium/magnesium removal can be increased effectively. The mixer is particularly suitable for mixing substances of liquid-solid mediums needing complete reaction.

Description

A kind of agitator

Technical field

The utility model relates to a kind of agitator, mainly is the used agitator of chemical precipitation method removing calcium and magnesium in the wet production nickelous sulfate process.

Background technology

The used agitator of chemical precipitation method removing calcium and magnesium in the wet production nickelous sulfate process; Be generally the screw-pushing type agitator; Because this kind agitator can only form stable laminar flow with solution; Can not make solution form turbulent flow, cause the precipitating reagent that is added fully to mix with solution and reach the purpose of complete reaction.So not only can cause reactant deposits at the bottom of the removing calcium and magnesium still and stop up the fluid pipeline, have a strong impact on production; Also can cause the increase of reactant consumption, the reduction of removing calcium and magnesium effect, finally cause nickelous sulfate product calcium-magnesium content to exceed standard and do not meet national standard, have a strong impact on economic benefit of enterprises and social benefit.

Summary of the invention

The purpose of the utility model is exactly the deficiency that exists to above-mentioned technology, provides a kind of reactant that can make fully to mix with solution, can improve the agitator of removing calcium and magnesium efficient again.This agitator can guarantee that the calcium-magnesium content in the nickelous sulfate product satisfies process conditions requirement, National standard.

The purpose of the utility model realizes through following technical scheme: a kind of agitator, comprise agitated reactor, and shaft is fixed in the stirring vane of shaft; It is characterized in that: stirring vane is three layers.

The following plane that roughly is of upper strata stirring vane above the stirring vane of middle level is many faceted pebbles solid, and is V-shaped above lower floor's stirring vane.

The utility model, the following plane that roughly is of its upper strata stirring vane presses down mixed solution, impel solution and on the abundant hybrid reaction of solution of turning over; Be many faceted pebbles above the stirring vane of middle level, can carry out the pusher stirring of upper-turn-type, make solution on different aspects, form turbulent flow, precipitating reagent is fully mixed with solution solution; Lower floor's paddle make the part unreacted completely precipitating reagent fully mix with solution at removing calcium and magnesium agitated reactor cone base, avoid unreacted completely precipitating reagent deposit at autoclave body bottom, effectively prevent the line clogging phenomenon that causes because of reactant deposits.Therefore this device can effectively improve removing calcium and magnesium efficient, reduces the use amount of precipitating reagent, reduces production cost.This agitator is particularly useful for the material that needs between the liquid-solid medium fully react is stirred.
