Liquid injection equipment used for carbon fiber storage battery

Abstract

The invention discloses liquid injection equipment used for a carbon fiber storage battery. The liquid injection equipment comprises a vacuum tank, a side tank group, an intermediate tank, a diaphragmpump, a liquid storage tank, waste liquid tanks, a vacuum pump and a controller, wherein the vacuum pump and the intermediate tank are communicated and connected and form a vacuumizing mechanism; thediaphragm pump and the liquid storage tank are communicated and connected and form a liquid supply mechanism; the side tank group and the waste liquid tank group are mounted on a side rack respectively; the side tank group is communicated and connected with the liquid supply mechanism and a liquid inlet nozzle group on the top of the vacuum tank respectively; the waste liquid tank group is communicated and connected with the vacuumizing mechanism and a liquid drainage nozzle group at the bottom of the vacuum tank respectively; and the vacuum tank is communicated and connected with the vacuumizing mechanism. According to the liquid injection equipment, the absorption difficulty of an AGM diaphragm for an electrolyte is reduced, the filling efficiency is improved, the degree of automation is improved, and the artificial processing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of battery liquid injection, in particular to a liquid injection device for a carbon fiber battery. Background technique [0002] The material of the electrode plate in the lead-acid storage battery is lead, but as the pollution problem becomes more and more serious, and the country’s environmental awareness becomes stronger and stronger, the electrode plate made of lead is gradually eliminated, and the carbon fiber composite zinc electrode plate is replaced. Carbon fiber composite zinc electrode plate complies with environmental protection requirements, gradually flourishes, and becomes an indispensable part in storage battery. [0003] There are many processes for manufacturing carbon fiber batteries, one of which is to charge the carbon fiber batteries with electrolyte. The electrolyte is added through the liquid injection hole on the tank cover after the tank cover is sealed. At present, carbon fiber b...

Problems solved by technology

[0004] However, with the increase of battery capacity, the chemical substances in the battery are more and more dense, and the AGM separator is more and more difficult to absorb the electrolyte.

In addition, the current equipment for adding electrolyte to carbon fiber batteries is relatively small, and can only add electrolyte to one or several carbon fiber batteries at a time, and it is all done manually, which has very low efficiency and high labor costs, which is not conducive to production manufacture
