Abstract

The invention discloses a continuous metering charging system of a reaction vessel. The continuous metering charging system of the reaction vessel comprises a container (1) and a flowmeter (4). The container is connected to the flowmeter by a pipe. The container is arranged at a position higher than a position of the flowmeter. The container is provided with a liquid inlet (2). The container is provided with a liquid discharge outlet above the container bottom surface. The continuous metering charging system of the reaction vessel realizes accurate metering, accurate control of the amount of a liquid fed into the reaction vessel, improvement of ferric phosphate product quality, and stabilization of ferric phosphate product quality.

Description

technical field [0001] The invention relates to a production equipment of lithium iron phosphate, in particular to a continuous metering feeding system of a reactor. Background technique [0002] Lithium iron phosphate (LiFePO 4 ) is mainly used for power batteries for electric vehicles. The crystal structure is olivine structure, which has the characteristics of high safety and long life. It is widely used in the field of power batteries such as electric vehicles and electric tools, and the field of energy storage equipment for wind power generation systems. At present, in the production process of lithium iron phosphate, the main iron raw material is iron phosphate. In the synthesis process of ferric phosphate raw materials, it is necessary to use a reactor for continuous feeding reaction. In order to produce high-quality raw material products, the continuous reaction volume must be strictly controlled. [0003] In the prior art, the continuous metering and feeding syst...
