Colloidal electrolyte agitator

Abstract

The invention relates to a colloidal electrolyte agitator, includes a tank and a pump having feed ports, the feed port of the pump is communicated with the feed port of tank bottom via a feeding channel, the discharge port is coummunicated with upper feed port of the tank via discharging channel that coummunicated with discharge port of colloidal electrolyte at the same time. The invention uses magnetic pump to agitate and mix the colloidal electrolyte, not only possessing advantage of saving energy, but also capable of dispersing gels into sluphuric acid solution completely because of magnetic pump agitating and mixing efficiency, and interaction of various materials in pump. The invention provides cooling jacket for tank and temperature sensor that can control temperture of mixture in tank according to demands by regulating flow of cooling liquid, which ensures high-efficiency dispersion of colloidal electrolyte at proper temperature, improves gels dispersion degree and speed and prolongs gelatine time.

Description

technical field [0001] The invention relates to a storage battery, in particular to a colloidal electrolyte stirrer for the storage battery. Background technique [0002] Colloidal electrolyte is a colloid formed by dispersing a certain proportion of silica sol or fumed silica into sulfuric acid solution. This kind of electrolyte has good thixotropy. At rest, the network-like silica gel fixes the sulfuric acid and water molecules in a solid state. Through the action of shear force, the colloid can become a solution again. Colloidal electrolyte is used in valve-regulated lead-acid batteries, and the microcracks formed by silica gel are good channels for hydrogen-oxygen recombination. The battery using colloidal electrolyte has uniform electrolyte concentration, no sulfuric acid stratification, and small self-discharge; the battery has good high and low temperature characteristics; it can avoid the thermal runaway phenomenon that is easy to occur in general AGM batteries, and...

AI Technical Summary

Problems solved by technology

[0003] The current colloidal electrolyte stirrer adopts a shaft-driven paddle structure, which has the following defects: first, the rotation of the paddle drives the electrolyte to flow and shear, and the torque of the stirring paddle is large, which requires high power for the motor and consumes a lot of energy; The solvent and sulfuric acid do not dissolve each other, so it is difficult for this kind of mixer to effectively disperse the network structure of the silica gel. The dispersed gel particles are large, and it is easy to cause the electrolyte to gel prematurely, which is not conducive to the perfusion of the electrolyte; the third is the colloid The electrolyte is easy to disperse when the temperature is high, and the high temperature accelerates the gelation rate at the same time. The current agitator lacks a temperature control device and cannot provide a suitable temperature
