And exhaust outlet, air inlet two and gas outlet are offered on the locular wall of the agglomerating chamber, and the air inlet one and gas outlet pass through pipe
Road is connected, and the top being provided with the pipeline in control valve, the agglomerating chamber and the shape of two side are arc, described cold
But outdoor, which is provided with heat abstractor, the cooling chamber, is provided with corresponding heat sink, is offered on the heat sink
Hot switching path, is connected between the hot switching path two ends and heat abstractor by heat conducting device.By in preheating chamber, burning
Tie in room and cooling chamber horizontal through same board-like transmission belt, be so easy to the streamline of LiFePO4 to sinter, preheating, burning
Knot, cooling are independent of each other, and can carry out simultaneously, so as to greatly improve production efficiency；By being opened up on the locular wall of preheating chamber
There are air inlet one and exhaust outlet, air inlet two and gas outlet, and air inlet one and gas outlet are offered on the locular wall of agglomerating chamber
By pipeline communication, the protective gas after use in agglomerating chamber can be so passed into preheating chamber, to the phosphoric acid in preheating chamber
Iron lithium is protected, it is achieved thereby that the reuse of protective gas, make use of protective gas to greatest extent, so as to reach
The effect of saving and protection gas, reduces production cost；By the way that the top in agglomerating chamber and the shape of two side are designed
For arc, furnace roof and the bulk strength of furnace wall are so strengthened, it is durable；By being provided with heat abstractor outside cooling chamber,
Corresponding heat sink is provided with cooling chamber, hot switching path, and hot switching path two are offered on heat sink
End can so be taken to the heat on heat sink by heat-conduction medium scattered with being connected between heat abstractor by heat conducting device
Radiated in thermal, its radiating is simple and convenient.
Preferably, being provided with sealing device on the preheating chamber and the outer wall of agglomerating chamber, so it is easy to seal whole burning
Freezing of a furnace.
Preferably, offering heat emission hole on the locular wall of the cooling chamber, so it is easy to radiating.
Preferably, being provided with ventilating fan in the heat emission hole, so it is easy to more rapidly and effectively radiate.
Preferably, the material of the transmission belt is spring steel, so it is easy to meet use intensity and hardness.
Compared with prior art, a kind of beneficial effect of LiFePO4 sintering furnace of the utility model：By by LiFePO4
Sintering furnace is designed as this structure, repeatedly using protective gas, and preheating, sintering and cooling subregion, streamline are sintered, and simultaneously will
Furnace wall is designed as arc, so as to reach the high effect of saving and protection gas, durable, production efficiency.
