Problems solved by technology

[0003] However, the following problems exist in the current oxidizing material during alkaline leaching. First, the traditional oxidizing material cannot be completely dissolved in water during alkaline leaching, making The uneven mixing of oxidized material and water affects the effect of alkali leaching of oxidized material; 2. During the alkaline leaching of existing oxidized material alkali leaching equipment, because the oxidized material and lye cannot be stirred evenly, the alkali leaching of oxidized material is not complete, Affect the alkali leaching effect of oxidizing materials, reducing the production quality of ammonium paratungstate

Abstract

The invention relates to oxidation material alkaline leaching equipment which comprises a bottom plate, a swinging device, a stirring device and a pre-dissolving device.The swinging device is installed on the bottom plate, the stirring device is installed on the swinging device, and the pre-dissolving device is installed on the stirring device. The oxidation material alkaline leaching equipment can solve the following problems existing in existing oxidation material alkaline leaching: 1, when a traditional oxidation material is subjected to alkaline leaching, the oxidation material cannot be completely dissolved in water, so that the oxidation material and the water are not uniformly mixed, and the alkaline leaching effect of the oxidation material is influenced; and 2, when conventional oxidizing material alkaline leaching equipment is used for alkaline leaching, the oxidation material and alkaline liquor cannot be uniformly stirred, so that the alkaline leaching of the oxidation material is incomplete, the alkaline leaching effect of the oxidation material is influenced, and the production quality of ammonium paratungstate is reduced.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an alkali leaching equipment for oxidizing materials. Background technique [0002] Ammonium paratungstate is a kind of chemical substance, mainly white crystal, there are two kinds of flakes or needles, ammonium paratungstate is one of the important tungsten products, it is often used to make metal tungsten powder made of tungsten trioxide or blue tungsten oxide, also used For the manufacture of ammonium metatungstate and other non-toxic compounds, used as additives in the petrochemical industry. With the continuous development of high-performance tungsten materials and tungsten alloys, the application prospects of high-purity ammonium tungstate are more broad. During the production of ammonium paratungstate, it is necessary to carry out alkali leaching operation on the oxidized oxidized material. [0003] However, the current oxidizing material has the following prob...
