Abstract

The invention discloses a telescoping extraction device for efficiently recovering valuable components of manganese slag. A liquid draining valve is arranged at the bottom of a heating tank body and aliquid introducing valve is arranged at the top of the heating tank body; the outer wall of the heating tank body is provided with a jacket; the jacket is internally provided with a heating coil; theupper end of the heating tank body is integrally connected with a heating tank cover through a flange; a casing pipe is arranged at the center of the heating tank cover; the casing pipe sleeves a sliding tube; a drain valve is arranged at the bottom of the sliding tube; liquid outlets are uniformly distributed at the lower part of the sliding tube; a plurality of sealing ring grooves are formed in the upper parts of the liquid outlets; the sealing ring grooves sleeve sealing rings; the flange is arranged at the middle part of the sliding tube and is provided with a hydraulic telescopic pole which controls the sliding tube to slide vertically and flexibly in the casing pipe and adjust the position of the sliding tube. The design adopts a telescoping Soxhlet leaching and extracting system which is matched with an ammonia nitrogen recycler to recover ammonia, so that the efficient recovery of the valuable components and ammonia nitrogen in the electrolytic manganese slag is realized; themanganese slag subjected to harmless treatment can be used as a raw material of cement and ceramics and finally resourceful utilization is realized. The telescoping extraction device has important application value.

Description

technical field [0001] The invention relates to a scalable extraction device for efficiently recovering valuable components of manganese slag, belonging to the technical field of chemical machinery equipment. Background technique [0002] The output of electrolytic manganese in my country accounts for more than 98% of the global output, and it is the main producer, consumer and exporter of electrolytic manganese metal in the world. For every 1 ton of electrolytic manganese produced in my country, 10-12 tons of electrolytic manganese slag will be discarded. By 2012, The stockpile of electrolytic manganese slag in my country has reached 77.84 million tons, and the annual discharge is increasing by 10 million tons. Electrolytic manganese slag is a mixture of acid leaching slag, sulfide slag and anode slag produced after acidolysis, neutralization, pressure filtration and impurity removal of manganese carbonate ore. At present, the vast majority of electrolytic manganese enterpr...
