A spray drum-type activated carbon mixing device for lead-carbon batteries

Abstract

The invention discloses a spray drum type lead-carbon battery activated carbon mixing and stirring device, which is characterized in that it comprises an inner cylinder, an outer cylinder, a cover plate, a rotating shaft and a spray system, and the bottom of the outer cylinder is provided with The outlet of the mixed liquid, the inner cylinder is connected with the vertically arranged rotating shaft and driven to rotate by the rotating shaft, and the side wall of the inner cylinder is provided with a plurality of holes, and the rotating shaft is driven by a motor to rotate; the spray system includes a A plurality of nozzles on the cover plate, and an external circulating liquid pump, the circulating liquid pump is respectively connected to the nozzles and the mixed liquid outlet through pipelines to form a circulation, and the nozzles are also connected to at least one raw material liquid pipeline, the raw material liquid pipeline With valve. The invention can effectively prevent the active carbon dust from flying, and can improve the uniform mixing of the active carbon in the aqueous solution to avoid the agglomeration of the active carbon.

Description

Technical field [0001] The invention belongs to a mixing and stirring device, and in particular relates to a solid-liquid mixing and stirring device for activated carbon powder and liquid modified raw materials. Background technique [0002] As the power source of new energy electric vehicles, lead-acid batteries are more and more used due to their excellent charge and discharge performance and long life. At present, the introduction of activated carbon components into lead-acid battery plates has the characteristics of supercapacitors. It can greatly improve the performance of lead-carbon batteries. However, the existing activated carbon directly added to the electrode plate has little performance improvement and needs to be modified. The modification of activated carbon is often accompanied by mixing and stirring of activated carbon powder and liquid modified raw materials. Due to the light and ultra-fine powder of activated carbon with a large specific surface area, during th...

However, the performance of the existing activated carbon directly added to the plate does not improve much, and it needs to be modified

The modification of activated carbon is often accompanied by the mixing and stirring of activated carbon powder and liquid modified raw materials. Due to the light weight and ultrafine powder of activated carbon with a large specific surface area, it is easy to float on the surface of the raw material liquid during the mixing process, and it is easy to agglomerate. Moreover, dust will be formed when feeding, which will bring adverse effects to the working environment.
