Abstract

The invention discloses a continuous type extractor for strontium sulfide, which comprises a closed type hydrolyzing tank, a movable mesh belt and a transmission device, wherein the movable mesh belt is supported by bipatch big roller chain riveted seamless steel tubes, and is dragged by the transmission device to move in the hydrolyzing tank. The closed type hydrolyzing tank is also provided with a material inlet, a water inlet, a water outlet and a slag outlet. The material inlet is formed in the upper part of one end of the hydrolyzing tank, and rightly faces the movable mesh belt. A distributor is arranged at the material inlet. The water inlet is arranged at the other end of the hydrolyzing tank. The invention further discloses an extraction method of strontium sulfide. According to the invention, a dynamic continuous extraction way is adopted, so that the mechanization degree is greatly increased, and the labor intensity of the worker is relieved; and continuous production is adopted, so that the quality of extracted liquid can be increased, and the undulating range of concentration of the extracted liquid is reduced, so as to be helpful for decreasing the control difficultyof extracting production.

Description

technical field [0001] The invention relates to a strontium sulfide leaching method and device. Background technique [0002] Strontium carbonate is an important material in the electronic information industry, such as magnetic materials, liquid crystal glass substrates, capacitors, and PTC electronic ceramics. , light industry, ceramics, fireworks, magnetic materials and other industries. [0003] The above-mentioned strontium compounds and alloys are obtained from strontium sulfide materials mined from strontium ore and processed in a rotary kiln, then leached to obtain an aqueous solution of strontium sulfide, and then further processed. The leaching of strontium sulfide is to immerse the solid material containing strontium sulfide in hot water at about 90°C to obtain an aqueous solution of strontium sulfide and remove the waste residue. Domestic strontium sulfide leaching methods include: spiral leaching, stirring barrel leaching, hanging basket leaching, static leachi...
