Description

Technical Field

When heat medium is added into the jacket through a heat medium inlet and the raw materials in the kettle body are heated to an optimal reduction reaction temperature, a driving motor drives the output end to drive the first pulley to rotate, and the first pulley drives the second pulleys on both sides to rotate through a belt, and the first pulley and the second pulley will respectively drive the first stirring shaft and the second stirring shaft to rotate in the kettle body through the first rotating rod and the second rotating rod during the rotation process, and the first stirring rod on the first stirring shaft and the second stirring rod on the second stirring shaft will rotate alternately in the kettle body, so as to stir and mix the raw materials in the kettle body in all directions without dead angles, and at the same time, during the stirring process, a scraper installed on the first stirring shaft through a connecting rod will rotate close to the inner wall of the kettle body.

[0004] A reduction reaction device generally requires passing a reducing gas into the reactor to cause the reactants inside to undergo a reduction reaction. Currently, the raw materials and gas inside the reactor are generally mixed by stirring. Since most reactors are in a vertical state, the raw materials will accumulate at the bottom of the reactor, with a small contact area with the gas, affecting the reaction efficiency. In addition, the existing reduction reaction device cannot quickly add gas to the reactor after the internal reaction gas is completely consumed. Utility Model Content
