Industrial crude iodine recovery stirring device

Abstract

The invention discloses an industrial crude iodine recovery stirring device, which comprises a sealing cover, wherein a gear shaft is arranged at the central position of the top of the sealing cover;a rack is arranged on the left side of the gear shaft; a moving rod is arranged at the left end of the rack; a cylindrical cam is arranged at the left end of the moving rod; and a supporting frame isarranged above the cylindrical cam, and the supporting frame is further arranged below the cylindrical cam. A braking device of the crude iodine recovery stirring device drives the rack to move back and forth by a cylindrical cam mechanism, the rack drives a stirring rod to rotate in the positive and negative directions, the stirring speed is small, the solution can be fully heated, the heating ismore uniform, and the rotation in the positive and negative directions can cause the solution to generate larger water fluctuation and more vapor dense, so that the iodine vapor still maintains a higher temperature during the transfer process, blocking plates on stirring fan blades can further generate larger water fluctuation, and the swinging plate can enlarge the stirring range.

Description

technical field [0001] The invention belongs to the technical field of crude iodine recovery, in particular to an industrial crude iodine recovery stirring device. Background technique [0002] Crude iodine is an iodine crystal containing impurities. Iodine plays an important role in people's production and life. Iodine and iodine compounds are widely used in modern industry, agriculture, national defense, science and technology and medicine. However, in the production of crude iodine And in the process of use, some crude iodine waste liquid will inevitably be produced. If these waste liquids are discharged, they will pollute the environment, so they need to be recycled. [0003] The most common recovery method is the sublimation method. During sublimation, the solution needs to be properly stirred, but the current stirring devices still have some shortcomings; most of the current stirring devices are directly driven by motors, and the speed is relatively fast. The solution...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of industrial crude iodine recovery stirring device, to solve the present stirring device proposed in the above-mentioned background technology, most of the current stirring devices are directly driven by motors, and the rotating speed is fast, so the solution cannot be heated and sublimated; The general stirring rod rotates in one direction, the heating temperature range is concentrated, and the temperature above is lower, which is not conducive to the transfer and desublimation of iodine vapor.
