Abstract

The invention provides an efficient sintering furnace and a production device of lithium iron phosphate, and relates to the technical field of battery material manufacturing. A hearth with a seal in afurnace body, a temperature control system, a propelling system and a heating and cooling system are included; the hearth is divided into a temperature rising area, a burning area and a cooling areain the direction from the inlet end to the outlet end; the temperature control system is arranged on the furnace body; the propelling system is arranged on the furnace body; the heating and cooling system comprises an interlayer metal sleeve, a gas way pipeline and an air source heat pump; the interlayer metal sleeve is provided with a hollow interlayer inner cavity, and the interlayer metal sleeve is installed in the cooling area of the hearth; cooling water is cyclically introduced into the interlayer inner cavity of the interlayer metal sleeve, and is used for lowering the temperature of the cooling area; the air source heat pump is connected with an inlet of the gas way pipeline, and is used for preheating protecting gas and introducing the preheated protecting gas into the gas way pipeline; and an outlet of the gas way pipeline communicates with the hearth, and is used for filling the hearth with the protecting gas after being preheated.

Description

technical field [0001] The invention relates to the technical field of battery material production, in particular to a high-efficiency sintering furnace and a lithium iron phosphate production device. Background technique [0002] The sintering furnace refers to the special equipment for obtaining the required physical and mechanical properties and microstructure of the powder compact through sintering. The sintering furnace can be used to dry the slurry on the silicon wafer, remove the organic components in the slurry, and complete the aluminum back field and grid wire sintering. [0003] Among the sintering furnaces in the prior art, the tunnel-type battery material sintering furnace used usually needs to be cooled by water circulation interlayer at the discharge port, and at the same time, it is necessary to pass through the middle section of the sintering furnace and the feed port and discharge port at both ends. Protective gas to control the oxidation / reduction atmosph...
