Atmosphere type lifting furnace for sintering

The invention discloses an atmosphere type lifting furnace for firing. The lifting furnace comprises a double-layer furnace body, the inner layer of the furnace body is provided with an inner container, and the inner container is cylindrical and is sequentially divided into an upper temperature area, a middle temperature area and a lower temperature area from top to bottom; wherein the bottom of the furnace body is communicated with a humidifying device, the humidifying device comprises a high-temperature humidifier and a low-temperature humidifier, the high-temperature humidifier and the low-temperature humidifier can be mutually switched, and a preheating device is further arranged between the humidifying device and the furnace body. According to the atmosphere type lifting furnace for sintering, the humidifiers are used for humidification treatment and preheating before nitrogen is introduced, decomposition and discharging of organic resin in a product can be effectively promoted, the two humidifiers with
