As shown in fig. 1. The utility model discloses smelt discharging equipment is including being the delivery outlet 2, the control valve of the liquid of smelting of radially seting up on the corresponding one side lateral wall 1 of smelting furnace body. The control valve comprises a valve core, a corresponding control mechanism, a bracket and the like. The valve core is a cone plug 5 correspondingly connected with the output hole 2. A launder 14 is provided in correspondence of the outlet hole 2. The support is a cantilever 3 which is correspondingly positioned above the launder 14 and is fixedly connected to the corresponding side wall of the smelting furnace, and the control mechanism is correspondingly arranged above the corresponding launder in a suspension type through the cantilever. The cone plug and the output hole of the smelting furnace are arranged coaxially.

The control mechanism comprises a joint control swing arm 4 connected with a cone plug 5, a rotating shaft 8, a corresponding action operator and the like. The joint control swing arm 4 is arranged in the vertical direction. The rotating shaft 8 comprises a rotating shaft main body part and a transfer device 8a, the transfer device 8a is formed by extending one corresponding end of the rotating shaft main body part to the outer side of the launder, the action operator comprises a force arm 7b of which one end is fixedly connected to the transfer device 8a and a rigid control lever 22 of which one end is movably hinged to the other end of the force arm 7b, and the rigid control lever 22 is provided with a two-position limiting steady-state device. The two-position limiting steady-state device comprises an upper stroke positioning convex body 23 and a lower stroke positioning convex body 23 which are connected to the other end of the rigid control rod 22 at intervals, and a stroke positioning blocking body 25 which is arranged on the corresponding fixed body 24 and respectively corresponds to the two stroke positioning convex bodies. The distance between the two stroke positioning convex bodies or the height of the two stroke positioning convex bodies is equal to the opening and closing stroke of the cone plug. The rigid operating lever may be disposed upward or downward, and the upper or lower end of the rigid operating lever is provided with an operating grip 27. The stationary body 24 may be a nearby on-site building, facility, or facility, etc.

The arm of force 7b is located the corresponding one side outside of cantilever, and the upper end of allies oneself with accuse swing arm 4 is located the open slot 3a of cantilever, and the upper end of allies oneself with accuse swing arm is fixed in pivot 8, and allies oneself with accuse swing arm and passes through 8 rotation types of pivot connection in cantilever 3. A coaxiality self-adaptive adjustment coupling device is arranged between the joint control swing arm and the plug rod 6 of the cone plug. The self-positioning closing sealing operation of the cone plug forms buffer allowance through a coaxiality self-adaptive adjustment coupling device, if the cone plug is closed in an initial stage, closing action and speed are reduced when the cone plug is subjected to large impact resistance, closing performance of the cone plug is improved and enhanced, meanwhile, the problems that the closing sealing degree is insufficient due to the change of the plugging degree of the cone plug under the conditions of working temperature change, use abrasion and the like of the cone plug can be avoided, and self-adaptive accurate searching and positioning in the operation process of the cone plug are achieved.

The cone plug 5 and the joint control swing arm are arranged at an included angle with each other on the corresponding vertical plane, and the included angle can enable the joint control swing arm to rotate around a rotating shaft of the joint control swing arm to a corresponding stable state position so as to enable the cone plug and the output hole to be basically the same as a central line, or enable the cone plug 5 to be plugged into the output hole 2 to form complete inosculation sealing when being closed. Each respective angle may be selected between 60-150 degrees.

The coaxiality self-adaptive adjustment coupling device comprises an accommodating guide open groove 13 which is arranged on one side of the lower end of the joint control swing arm 4 and corresponds to the plug rod, a hook type open coupling groove 11 which is arranged on the other side of the lower portion of the joint control swing arm 4 and corresponds to the accommodating guide open groove 13 and the plug rod 6 respectively, and a supporting shaft 12 which is rotatably connected between the two opposite sides of the plug rod 6 and the hook type open coupling groove 11 of the joint control swing arm 4. The cone plug is arranged in the joint control swing arm 4 in a self-balancing suspension type all-dimensional movable manner through the plug rod of the cone plug via the accommodating guide open groove 13, the hook type open coupling groove 11 and the supporting shaft 12. The top wall of the accommodating guide open groove is an inclined top wall surface which inclines downwards from the inner side to the outer side, and the inclined top wall surface inclines downwards and extends to the plug rod 6 close to the cone plug to form a single-side horn type accommodating guide open groove so as to stabilize the operation of the cone plug and prevent the cone plug from being separated.

And a handle-bar type gravity balance body 15 fixedly connected with the free end of the plug rod of the cone plug. The hook type open coupling groove 11 is inclined downward in the cone plug opening direction, and the lower portion thereof is deviated from the recess toward the cone plug opening direction side. Which may further ensure a high reliability of the cone plug in advance. The handle rod type gravity type multi-functional stable rod and the cone plug 5 are arranged at an included angle with the joint control swing arm on the corresponding vertical plane respectively, and the included angle can enable the joint control swing arm to rotate around a rotating shaft of the joint control swing arm to a corresponding stable position so as to enable the cone plug 5 to be plugged into the output hole 2 to form complete fit sealing when the cone plug is closed.

The utility model discloses have cone stopper self-align to close sealed operation buffer function, if close the initial stage, the cone stopper slows down when receiving great impact resistance and closes action and speed, improves and improves the closing performance of cone stopper, simultaneously, can avoid the cone stopper because of operating temperature's change, use under the circumstances such as wearing and tearing, the degree of filling in of cone stopper changes and the not enough scheduling problem of degree of sealing of closing that leads to, fundamentally improves and improves the closing performance of cone stopper, close degree of sealing and security performance.

When the device is operated, the holding part of the rigid operating lever is held by hand, the rigid operating lever is pushed upwards or downwards by force to overcome the weight of the joint control swing arm, the cone plug and the like, a corresponding one of the two stroke positioning convex bodies is clamped with the stroke positioning baffle body 25, the stroke positioning baffle body blocks the stroke positioning convex body, and the rigid operating lever is positioned at the position, namely the cone plug is in an opening or closing stable state. Thereby realizing that the cone plug is controlled by shifting to the position above or below the outer side of the launder. The high-temperature environment operation of the operation personnel close to the launder and the smelting furnace can be avoided. It is very safe and practical.

In another embodiment, the handle-bar type gravity balance body 15 can be provided with a balance sleeve sleeved at one end thereof in a limiting manner through a rubber winding layer, so as to adjust and balance the self-gravity. The other corresponding control modes of this example can be similar to the above-mentioned embodiment.

In another embodiment, the plug rod is hinged to the joint control swing arm 4 through a pin shaft, a self-positioning cantilever spring is connected between the plug rod and the joint control swing arm, and the cone plug corresponds to the output hole when being closed through the self-positioning cantilever spring.
