Sand-like strong alkali metal filtering washing system and washing process

Abstract

The invention discloses a sand-like strong alkali metal filtering washing system and washing process. The system comprises a washing device, a material feeding pipeline, an air inlet pipe, a blow-down pipe, a white oil and solvent discharging pipe and a solvent washing pipeline, wherein the washing device comprises a tank body, a stirrer and a filtering assembly; a material inlet is arranged on the top of the tank body; an air inlet and a blow-down opening are arranged at the front side and the rear side of the material inlet respectively; a strong alkali metal outlet is arranged on the side wall of the tank body; a white oil and solvent outlet is arranged at the bottom of the tank body; the filtering assembly comprises a filtering net, wherein the filtering net is installed at the lower part of the tank body; the stirrer comprises a transmission device and a stirring assembly; the stirring assembly comprises a stirring shaft and a paddle; and the lower end of the stirring shaft is connected with the paddle. The sand-like strong alkali metal filtering washing system provided by the invention can carry out combination operations, i.e. filtering, stirring, washing and back-flashing on sand-like strong alkali metal and white oil mixtures; the white oil in the sand-like strong alkali metal can be isolated effectively, and the sand-like strong alkali metal is washed by the solvent, so that the system is a specific device used in the process of sand-like strong alkali metal washing.

Description

technical field [0001] The invention belongs to the field of sandy strong alkali metal treatment, in particular to a sandy strong alkali metal filtering and cleaning system and a cleaning process. Background technique [0002] After the strong alkali metal is dispersed into highly active sand-like particles through white oil or mineral oil, it is necessary to separate the white oil remaining on the surface of the sand-like strong alkali metal to improve product quality, because the sand-like strong alkali metal has small particle size and high activity , so that the separation difficulty increases, and the separation effect of the current separation equipment is poor, and the safety is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a filter cleaning system for sand-like strong alkali metal with simple structure, good separation effect, safety and reliability. [0004] In order to solve the problems of...
