Abstract
The invention relates to a production device for preparing pure-phase cobalt tetraoxide through liquid-phase synthesis. According to the device, an oxidant feeding pipe, a cobalt liquid feeding pipe and an alkali liquid feeding pipe extend into a reaction kettle vertically with a direction parallel to the axis of the reaction kettle body and with adjustable heights. The oxidant feeding pipe, the cobalt liquid feeding pipe and the alkali liquid feeding pipe are 5-50cm away from the inner wall of the reaction kettle body. The lower pipe ports of the cobalt liquid feeding pipe and the alkali liquid feeding pipe are higher than the lower pipe port of the oxidant feeding pipe. A plane formed by the lower pipe ports of the oxidant feeding pipe, the cobalt liquid feeding pipe and the alkali liquid feeding pipe forms an included angle of 0-60 DEG with the horizontal plane. The position of stirring blades is between the planes of the highest and lowest lower pipe ports of the three feeding pipes. The device provided by the invention has a simple structure, and is convenient to operate. During a cobalt tetraoxide production process, an obtained product is changed with the change of reaction rate, such that pure cobalt tetraoxide can be obtained.
Description
Technical field
The present invention relates to a kind of cobaltosic oxide production equipment, is the process units that a kind of liquid phase synthesis prepares pure phase cobaltosic oxide specifically.
Background technology
In the generative process of cobaltosic oxide, in the reaction that preparation cobalt liquid and preparation alkali lye are oxidized at blowing air, because the intensity of reactive site oxidation is different, the cobalt oxide generated forms difference: a kind of shaping loose, the jolt ramming and the pine that affect particle fill on the low side, and specific surface is higher, and these material are as made lithium battery, battery compacting will be affected, thus reduce battery containing electricity.Another kind of shaping crystallization, comprises during this grain forming or the more sodium of crystallization, by XRD analysis still containing hydroxy cobalt oxide, does not meet customer requirement.
Summary of the invention
The present invention intends providing a kind of structure simple, and simple operation, at cobaltosic oxide, because of reaction rate change, product changes the process units obtaining pure property cobaltosic oxide thereupon in process of production
The technical solution used in the present invention is: a kind of liquid phase synthesis prepares the process units of pure phase cobaltosic oxide, comprise reaction kettle body, oxidant feed pipe, cobalt liquid feed pipe, alkali lye feed pipe and paddle, reaction kettle body is provided with overfall, described oxidant feed pipe, cobalt liquid feed pipe and alkali lye feed pipe are all parallel to reaction kettle body axis and stretch in reaction kettle body, oxidant feed pipe, cobalt liquid feed pipe and alkali lye feed pipe distance reaction kettle body inwall 5-50 centimetre, the lower nozzle of cobalt liquid feed pipe and the lower nozzle of alkali lye feed pipe are higher than the lower nozzle of oxidant feed pipe, oxidant feed pipe, the plane of the lower nozzle formation of cobalt liquid feed pipe and alkali lye feed pipe three pipe is horizontal by 0-60 degree angle, the height of paddle is in oxidant feed pipe, between mouth of pipe horizontal plane high and minimum in the lower nozzle of cobalt liquid feed pipe and alkali lye feed pipe three pipe.
Further, described oxidant feed pipe, cobalt liquid feed pipe and alkali lye feed pipe three are managed and are projected as equilateral triangle in the horizontal plane.
Further, the described equilateral triangle length of side is the 0.5-0.8 of reactor diameter.
Further, the 0.35-0.45 of described paddle blade length and reactor radius.
Again further, the lower nozzle of described cobalt liquid feed pipe is positioned at 0-25cm on stirring, and the lower nozzle of alkali lye feed pipe is positioned at 0-40cm on stirring, and air feed pipe is positioned at 0-60cm under stirring.
React and sent into by oxidant feed pipe, cobalt liquid feed pipe and alkali lye feed pipe, stir, kettle diameter relatively concrete, take into account the adjustment of reaction key element simultaneously, produce the product met.Cobalt chloride solution first carries out degree of depth oil removal treatment, is configured to the cobalt liquor needing concentration, adds additive in proportion, react in special reactor with liquid caustic soda, pass into air and be oxidized, by controlling reaction rate, control particles generation environment, thus produce the cobaltosic oxide of pure phase.
The plane formed by regulating the lower nozzle of three feed pipes and horizontal plane angle, in conjunction with the adjustment of the relative distance of control three feed pipes distance and still wall, preparation pure phase obtains cobaltosic oxide, oxidation completely, grain forming is better, and particle jolt ramming >=2.8 g/ ㎝ 3, pine dress >=1.7 g/ ㎝ 3, sodium≤0.030%, cobalt content >=69.5%, particle are spherical.Operating process of the present invention is easy, production efficiency is high, labor strength is little.
