Material discharge device for vertical furnace

The invention discloses a material discharge device for a vertical furnace, comprising a material blanking pipe, a gate valve, a rotating material discharge valve, an upper sealing valve, a discharged material tank, a material flow regulating valve and a lower sealing valve. The material discharge pipe is provided with at least two material dividing pipes; the gate valve is arranged at the inlet of the material discharge pipe or the outlets of the material dividing pipes; the rotating material discharge valve is arranged on the material dividing pipes and below the gate valve; the upper sealing valve is connected with the outlet of the rotating material discharge valve or the outlets of the material dividing pipes; the discharged material tank is connected with the outlet of the upper sealing valve; the material flow regulating valve is connected with the outlet of the discharged material tank; the lower sealing valve is connected with the outlet of the material flow regulating valve; and the discharged material tank is provided with a uniform pressure discharge interface. Due to the alternative work of equipment on the material flow paths of the material dividing pipes, the furnace material can be discharged continuously, and the vertical furnace can work continuously and efficiently. As the discharged material tank is provided with the uniform pressure discharge interface, the vertical furnace can discharge materials smoothly under pressure or normal pressure, and the material discharge device can work reliably and stably. The equipment in the material discharge device adopts the module design and can be repaired independently, so that the repair time is saved, and the maintenance cost is reduced.
