So set up, make second sealing washer 6 and second mounting groove 7 zonulae occludens through interference fit, cooperate through the barrel wall in the bin outlet outside of second sealing washer 6 and high-speed mixer, realize sealed effect.

In this embodiment, the top plate 5 is in a circular truncated cone shape, and the diameter of the top plate 5 gradually increases from the end close to the plug structure 1 to the end far from the plug structure 1. That is, the side surface of the top plate 5 is a tapered surface which matches with the wall surface of the cylinder outside the discharge port of the high-speed mixer, and the inclination degree and the inclination direction of the side surface of the top plate 5 are adapted to the wall surface of the cylinder outside the discharge port of the high-speed mixer. This arrangement enables the top plate 5 and the second gasket 6 to be in good sealing contact with the wall surface of the cylindrical body outside the discharge opening. Further, a rib 51 is formed at one end of the top plate 5 connected to the plug structure 1 to extend outward from the side surface of the plug structure 1. After the top plate 5 moves to the cylinder in place, the discharge valve is limited by the matching of the flange 51 and the wall surface of the cylinder. The top plate 5 is collinear with the axis of the plug structure 1.

In this embodiment, the discharging driving mechanism may adopt an existing driving structure such as an air cylinder; the first sealing ring 4 is made of PTFE (polytetrafluoroethylene) material; the baffle 12 is made of carbon steel plate; the top plate 5, the baffle plate 12 and the plug 11 are connected through a countersunk head screw 8.

Example 2:

referring to fig. 7, 8 and 9, a high-speed mixer of the embodiment of the present invention, this high-speed mixer includes barrel 100, is provided with a bin outlet 101 in the lateral wall lower part of barrel 100, is provided with the discharge valve that is used for opening or closing this bin outlet 101 in this bin outlet 101 department, and this discharge valve adopts the utility model discloses discharge valve in above-mentioned embodiment 1, the concrete structure of this discharge valve is no longer repeated here.

By arranging the discharge valve of the utility model at the discharge port 101 of the high-speed mixer, the installation accuracy requirement of the plug structure 1 and the discharge port 101 can be reduced by the automatic centering action of the first sealing ring 4 in the discharge valve, the use requirement can be met without welding, the plug structure 1 can be matched with the high-speed mixer of the same model at will, the installation time and the cost of the discharge valve are effectively reduced, and the related spare part inventory is reduced; and, after first sealing washer 4 became invalid, accessible second sealing washer 6 seals bin outlet 101, forms second seal structure, effectively reduces the hourglass material phenomenon.

Specifically, referring to fig. 7, 8 and 9, in the present embodiment, a truncated cone-shaped groove 102 is provided on the cylinder wall of the cylinder 100 outside the discharge opening 101, and the diameter of the truncated cone-shaped groove 102 gradually increases from the end close to the discharge opening 101 to the end far away from the discharge opening 101; the discharge opening 101 is shaped as a cylindrical hole. The inclination and direction of the slope of the truncated cone-shaped groove 102 correspond to the side of the top plate 5 in the discharge valve. And a second sealing structure is formed by matching the inclined surface of the circular truncated cone-shaped groove 102 with the side surface of the discharge valve top plate 5 and the second sealing ring 6.
