Reaction kettle with smashing function for sodium pyrosulfate production

Abstract

The invention discloses a reaction kettle with a smashing function for sodium pyrosulfate production. The reaction kettle comprises a reaction kettle body, a driven roller, a fixing plate, a stirringmotor, stirring blades, a discharging outlet, a smashing motor and a driving roller; a feeding inlet is formed above the reaction kettle body, a guide plate is arranged below the feeding inlet, the driven roller and the driving roller are arranged below the guide plate through the driven shaft and the driving shaft respectively, the fixing plate is welded to the interior of the reaction kettle body, the stirring motor is arranged at the lower end of the reaction kettle body, the stirring blades are welded to the outer side of a stirring shaft, the discharging outlet is formed in the lower endof the reaction kettle body, and the smashing motor is arranged on the outer side of a protective outer shell through a driving shaft. According to the reaction kettle with the smashing function for sodium pyrosulfate production, the lower portions on the outer sides of the driven roller and the driving roller are each provided with an anti-sticky plate, the effect of scraping away raw materials attached to the surfaces of the driven roller and the driving roller is achieved, and raw materials can fall into the reaction kettle body conveniently.

Description

technical field [0001] The invention relates to the field of sodium pyrosulfate reaction kettle technology, in particular to a reaction kettle for producing sodium pyrosulfate with a crushing function. Background technique [0002] Sodium pyrosulfate, in the form of colorless translucent crystals or white lumps, is the sodium salt of pyrosulfuric acid, which can be obtained by heating and decomposing sodium bisulfate. In this reaction, sulfur trioxide is produced, and then reacted with sodium sulfate produced by decomposition. Sodium pyrosulfate. [0003] But existing sodium pyrosulfate production reactor, when sodium pyrosulfate raw material is added in reactor and reaction solution is produced, is inconvenient to the fragmentation of sodium pyrosulfate raw material, and is unfavorable to the cleaning of crushing roll surface. Contents of the invention [0004] The object of the present invention is to provide a kind of reactor with pulverizing function for producing sod...
