Automatic electrolyte preparation device and method

Abstract

The invention discloses an automatic electrolyte preparation device and method. The device comprises a controller, a feeding mechanism and an electrolyte preparation mechanism. The feeding mechanism comprises a housing, a stepping motor, a plurality of storage hoppers and a plurality of weighing hoppers. The controller controls the simultaneous feeding by the multiple storage hoppers into the multiple weighing hoppers, after all the weighing hoppers weigh a preset feeding amount of materials, the controller controls the stepping motor so as to drive the weighing hoppers to rotate, the multipleweighing hoppers are sequentially aligned to a blanking port, and materials fall into the electrolyte preparation mechanism. The electrolyte preparation mechanism is located below the feeding mechanism, the controller controls the electrolyte preparation mechanism in terms of mixing water and the materials added by the feeding mechanism evenly to prepare electrolyte. The automatic electrolyte preparation method includes: utilizing the control of the controller to realize weighing, blanking, water adding and electrolyte preparation in sequence. The device and method realize automatic preparation of electrolyte, increase the preparation speed, improve the efficiency, can guarantee continuous conveying of electrolyte into a metal-air battery, and improve the power generation efficiency.

Description

Technical field [0001] The present invention relates to the field of metal-air batteries, and more specifically, the present invention relates to an automatic electrolyte preparation device and method. Background technique [0002] Metal-air batteries use metals with negative electrode potentials such as magnesium, aluminum, zinc, mercury, iron, etc. as the negative electrode, and oxygen or pure oxygen in the air as the active material of the positive electrode. The electrolyte solution of metal-air battery generally uses alkaline electrolyte aqueous solution. Metal-air batteries are widely used due to their high specific energy, low price and stable performance. [0003] Taking an aluminum-air battery as an example, it uses high-purity aluminum (99.99% aluminum) as the negative electrode, oxygen as the positive electrode, and potassium hydroxide (KOH) or sodium hydroxide (NaOH) aqueous solution as the electrolyte. Aluminum takes in oxygen and produces a chemical reaction when th...
