Equipment and method for producing sodium pyroantimonate by pure oxygen oxidation method

Abstract

The invention discloses equipment and method for producing sodium pyroantimonate through a pure oxygen oxidation method, and belongs to the technical field of sodium pyroantimonate production.The equipment comprises a reaction kettle mechanism, a centrifugal mechanism and a drying mechanism which are sequentially installed from top to bottom; the reaction kettle mechanism comprises a reaction kettle shell, a feeding pipe inserted into one side of the top of the reaction kettle shell and a transmission motor mounted in the center of the top of the reaction kettle shell, the output end of the transmission motor penetrates through the top of the reaction kettle shell and is coaxially connected with a rotating rod, and a plurality of stirring plates are uniformly connected to the side wall of the rotating rod; the top and the bottom of each stirring plate are evenly connected with a plurality of auxiliary plates, and a connecting plate is connected between the sides, away from the rotating rod, of the multiple stirring plates. According to the equipment for producing the sodium pyroantimonate through the pure oxygen oxidation method, the reaction efficiency in the reaction kettle shell is higher, the utilization rate of raw materials is higher, the occupied area is smaller, and more space is saved.

Description

technical field [0001] The invention belongs to the technical field of sodium pyroantimonate production, in particular to an equipment for producing sodium pyroantimonate by a pure oxygen oxidation method, and also relates to a production method of the equipment for producing sodium pyroantimonate by a pure oxygen oxidation method. Background technique [0002] Sodium pyroantimonate is mainly used as a clarifying agent for picture tube glass bulbs, and also as a flame retardant for textiles, plastics, and building materials. It is soluble in tartaric acid, concentrated sulfuric acid, etc., slightly soluble in alcohol and ammonium salt, and insoluble in acetic acid and dilute alkali. And dilute inorganic acid, which is mainly prepared by wet method, in order to improve the efficiency of production, it is necessary to continuously improve the production equipment and methods. [0003] For example, the application number is CN201620924655.2, a kind of reactor used for the produ...

AI Technical Summary

Problems solved by technology

[0004] However, the existing devices have the problems that the reaction efficiency in the reactor shell is not high enough, and the utilization rate of raw materials is not high enough.
