A kind of precipitation preparation device of iron oxide black based on ferrous sulfate solution

Abstract

The invention discloses a precipitation preparation device for iron oxide black based on ferrous sulfate solution, which includes a main body and a control motor. The bottom of the main body is provided with a base, and the outer surface of the upper end of the base is fixedly connected with a solution mixing chamber. The outer surface of the bottom end of the solution mixing chamber is fixedly equipped with a feeding device, the inner surface of the solution mixing chamber is inserted with a rotating rod, and the outer surface of the rotating rod is covered with a stirring mechanism. In the present invention, through the transmission mechanism and the movable mechanism provided, after the second connecting pipe and the first connecting pipe are proportioned, the rotating rod can be rotated by controlling the operation of the motor, and the stirring mechanism can be rotated through the rotation of the rotating rod. Stir the solution, and when the stirring blade is stirring, the air valve can be set to release the air during stirring, so that the contact surface between the air and the solution is larger to make the reaction more complete, and the air and the solution are accelerated. oxidation.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a precipitation preparation device for iron oxide black based on ferrous sulfate solution. Background technique [0002] Iron oxide black is commonly known as ferric oxide, which exists in nature in the form of magnetite. It is one of many iron oxides, including the rare ferrous oxide and ferric oxide called hematite, which contains ions and is black in laboratory grade Powder, which is permanently magnetic and ferrimagnetic, but is sometimes mistakenly considered ferromagnetic. The most widely used use of Fe3O4 is as a black pigment. As a pigment, Fe3O4 is more synthesized than obtained from Extracted from natural minerals, because the size and shape of pigment particles can be regulated by production methods. At present, there are three main production processes for iron oxide black in my country, which are addition method, precipitation oxidation method and ammonia ...
