Comprehensive efficient centrifugal machine for sodium iodide production

Abstract

The invention discloses a comprehensive efficient centrifugal machine for sodium iodide production. The comprehensive efficient centrifugal machine for sodium iodide production comprises a tank body, a tank cover and a fine-hole filter screen, the bottom of the front end of the tank body communicates with a discharge valve which is obliquely distributed, the tank cover is installed at the top of the tank body, a driving motor which is vertically distributed is installed at the bottom of the tank body, a transmission shaft is in transmission connection with the top of the driving motor and located on the inner side of the tank body, and the fine-hole filter screen is fixedly connected to the middle of the transmission shaft. According to the comprehensive efficient centrifugal machine for sodium iodide production, firstly, a comprehensive centrifugal structure is adopted, a solution can be subjected to comprehensive drainage and centrifugal separation operation, the solid-liquid layering rate is increased, and therefore the solid-liquid centrifugal separation efficiency of the solution is improved, secondly, a lifting and filtering type slag discharging structure is adopted, solid impurities obtained after centrifugal separation can be rapidly filtered out of the solution, conveyed and collected in a centralized mode, and the participation of a procedure of manually separating and filtering solid impurities is reduced, so that the production efficiency of the sodium iodide is improved.

Description

technical field [0001] The invention relates to the technical field of sodium iodide processing equipment, in particular to a comprehensive high-efficiency centrifuge for sodium iodide production. Background technique [0002] Sodium iodide is an inorganic compound with a chemical formula of NaI and a molecular weight of 149.89. It is a colorless cubic crystal or white granular substance. It is used as a raw material for iodine production and is used in medicine and photography. The acidic solution of sodium iodide produces hydrogen iodide. It is acid and shows reducing property, tastes salty and slightly bitter, can be dissolved in glycerin, and has strong hygroscopicity. Nowadays, after the sodium iodide is prepared by the eight iron iodide method, there will be large particles of iron filings and precipitated impurities in the solution, and the solution needs to be centrifuged through a centrifuge, but the existing centrifuges for sodium iodide production still exist Dis...
