[0033] The utility model provides a material discharge switch.

[0034] like Figures 1 to 5 The discharge switch shown includes a driving mechanism 1 and a flow control box 2. The flow control box 2 is respectively provided with a connecting through hole 21 and a guide groove 22. The connecting through hole 21 is connected to the guide groove 22. The flow control box 2 is used to be embedded in the side wall of the reduction furnace so that the connecting through hole 21 is connected to the reduction furnace, and the notch of the guide groove 22 is connected to the outside of the reduction furnace; the driving mechanism 1 is used to penetrate into the reduction furnace to open and close the connecting through hole 21, so that the driving mechanism 1 controls the opening and closing of the connecting through hole 21 and the opening and closing time.

[0035] The flow control box 2 connects the inside and outside of the reduction furnace, and controls the opening and closing of the connecting through hole 21 through the driving mechanism 1 to realize mechanized control of the discharge and discharge amount, effectively reducing the labor intensity of the staff and facilitating the control of the discharge amount and discharge process.

[0036] The drive mechanism 1 includes an electric cylinder 11 and a discharge drill rod 3. The output end of the electric cylinder 11 drives one end of the discharge drill rod 3, and the other end of the discharge drill rod 3 is used to extend into the reduction furnace and insert into the connecting through-hole 21 to close the connecting through-hole 21. The electric cylinder 11 is used to drive the discharge drill rod 3 to move vertically so that the discharge drill rod 3 opens the connecting through-hole 21. When discharge is required, the electric cylinder 11 controls the discharge drill rod 3 to move vertically upward, driving the discharge drill rod 3 away from the connecting through-hole 21, opening the connecting through-hole 21, so that the liquid material flows out of the reduction furnace through the connecting through-hole 21 and the guide groove 22 in sequence. When the discharge volume reaches the set value, the electric cylinder 11 controls the discharge drill rod 3 to move vertically downward, driving the discharge drill rod 3 to insert into the connecting through-hole 21, closing the connecting through-hole 21.

[0037] The drive mechanism 1 also includes a fixed frame 12, which defines a vertical passage. An electric cylinder 11 is mounted at the top of the fixed frame 12, through which the discharge drill rod 3 is inserted into the reduction furnace. The fixed frame 12 is positioned at the top of the reduction furnace and serves to initially restrict the vertical movement of the discharge drill rod 3.

[0038] The discharge drill rod 3 includes a rod body 31 and a closed end 32. The output end of the electric cylinder 11 is connected to one end of the rod body 31, and the closed end 32 is arranged at the other end of the rod body 31. The electric cylinder 11 is used to drive the closed end 32 to move vertically through the rod body 31 so that the closed end 32 is inserted into the connecting through hole 21 to close the connecting through hole 21.

[0039] Specifically, the rod body 31 and the closed end 32 are integrally formed.

[0040] The radial width of the closed end 32 decreases from the end of the closed end 32 close to the rod body 31 to the end of the closed end 32 away from the rod body 31 ; the radial width of the rod body 31 is greater than the aperture of the connecting through hole 21 .

[0041] Specifically, the closed end 32 is tapered.

[0042] The discharge switch further comprises a guide sleeve 4, which has a limit hole through which the discharge drill rod 3 passes; the limit hole is coaxially arranged with the connecting hole 21. The guide sleeve 4 cooperates with the fixing frame 12 to ensure the vertical movement of the discharge drill rod 3.

[0043] The discharge switch further comprises a guide tube 5, one end of which is connected to the guide groove 22. The arrangement of the guide tube 5 facilitates the drainage of the liquid.

[0044] The flow guide tube 5 and the flow control box 2 are detachably connected.
