[0025] Valve shell 1 is provided with baffle 19, and baffle 19 is located directly above rotating shaft 4, and the purpose of arranging baffle 19 is to prevent material from contacting rotating shaft 4, and the left and right sides of valve shell 1 are provided with openable and closable side doors 20, and the purpose of arranging side doors 20 is to facilitate opening side doors 20 to maintain the internal parts of valve shell 1.

[0026] The outer side of valve shell 1 is provided with bearing seat 7, bearing 8 is installed on bearing seat 7, and the front and rear ends of rotating shaft 4 are connected with bearing 8, wherein counterweight rod 9 is installed on the front and rear ends of rotating shaft 4, and the weight of counterweight rod 9 is greater than that of discharging flap 5, so that under the action of no external force, counterweight rod 9 drives discharging flap 5 to rotate until two discharging flaps 5 abut together to achieve force balance, and the periphery of counterweight rod 9 is provided with cover body 10, and the top of cover body 10 is provided with oil filler hole 11.

[0027] The middle part of valve shell 1 is provided with vibration motor 17, and vibration motor 17 is arranged to prevent material from accumulating on the inner wall of valve shell 1 to cause flow obstruction, and the side of the middle part of valve shell 1 away from vibration motor 17 is provided with observation hole 18 (which can be used to monitor the air lock condition of equipment and the material flow condition at any time).

[0028] The middle part of the inner wall of valve shell 1 is provided with sealing soft curtain 12, and the back of sealing soft curtain 12 is provided with counterweight block 13, and the bottom of sealing soft curtain 12 is attached to the inner wall of discharge outlet 3.

[0029] The bottom of the valve shell 1 is provided with a housing 14, the housing 14 is provided with a rotatable winding shaft 15, both ends of the winding shaft 15 are provided with a clockwork spring 16, the winding shaft 15 is wound with a traction rope 21, the end of the traction rope 21 is connected with the sealing soft curtain 12 through the valve shell 1, the sealing soft curtain 12 is automatically attached to the inner wall of the valve shell 1 under the action of gravity, and on the other hand, the sealing soft curtain 12 is also attached to the inner wall of the valve shell 1 under the constraint of the traction rope 21.

[0030] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0031] In use, the feed inlet 2 at the top of the valve shell (also called sealing valve) is communicated with the discharge port of the vertical mill, during normal operation of the vertical mill, the left and right lower discharge flaps 5 are tightly matched through the magnets 6 at the ends, at the same time, the sealing soft curtain 12 is lowered under the action of gravity, and the bottom of the sealing soft curtain 12 is tightly attached to the inner wall of the discharge port 3 of the valve shell 1, through the above two sealing barriers, the purpose of locking air is achieved.
