Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blanking assembly and aperture valve, in particular to a discharge pipe structure which is not easy to be blocked and easy to diffuse. BACKGROUND

[0002] In the known steelmaking technology, after the converter finishes discharging steel, a composite refining slag is added at the slag hole on the platform behind the furnace. However, after the steel is discharged, the refining slag is added, and because the density of the refining slag is less than the density of the molten steel, the reaction contact area is small, so that the refining slag will accumulate on the molten steel, which will cause inclusions in the molten steel and affect the quality of the molten steel.

[0003] In the prior art, a stirring assembly (such as a spiral blade or a striking rod) is arranged in the discharge pipe, but arranging the stirring assembly in the discharge pipe will make it difficult to control the speed of discharging, especially in the case of large discharging amount, which will easily cause the narrow part of the discharge pipe or the discharge structure to be blocked by the refining slag. In addition, the traditional valve structure (shut-off type, rotating type) with the stirring assembly penetratingly arranged in the discharge pipe cannot realize the adjustment of the discharging amount.

[0004] Although the utility model with the publication number CN203997585U discloses a vibrating discharge valve which adopts an aperture valve, the purpose of the aperture valve is to improve the problem of material accumulation and bridging during the discharging process of the aperture valve, and to realize the uniform and continuous discharging of powder material or granular material according to certain flow requirements. However, the aperture structure cannot be used to arrange the stirring assembly, and there is no technical inspiration for applying the aperture structure to the discharging amount adjustment and control of the discharge pipe with the stirring assembly. SUMMARY

[0006] In view of the deficiencies of the prior art, the present application provides a discharge pipe structure which is not easy to be blocked and easy to diffuse, and solves the following technical problems:

[0007] 1. The dispersion degree of the existing slag adding device is not high;

[0008] 2. The method of using the stirring assembly to improve the dispersion degree of the slag adding device will not be able to set the structure for flow adjustment because the stirring assembly is arranged in the discharge pipe;

[0009] 3. The center structure of the existing aperture valve is not suitable for the penetrating part such as the stirring assembly.

[0010] (II) Technical solutions

[0011] To achieve the above objectives, the present invention provides the following technical solution: a discharge pipe structure that is not easily clogged and is easy to diffuse, comprising a discharge pipe and a stirring component, wherein the stirring component is disposed inside the discharge pipe and is used to stir the discharge of the discharge pipe; an aperture valve is disposed inside the discharge pipe, wherein the aperture valve has a through hole in the center for the stirring component to pass through, and the aperture valve is used to adjust the discharge speed of the discharge pipe.

[0012] Preferably, the aperture valve includes a chassis with a circular window in the center. Several baffles are rotatably connected above the circular window. Several main rotating shafts are located around the circular window at the upper end of the chassis. Each of the baffles has a rotating cap at its upper end, which is fitted onto the main rotating shaft. Two auxiliary rotating shafts are also located at the upper end of the chassis. A power gear is located on one side of each of the two auxiliary rotating shafts. A rotating column is located at the lower end of each power gear. The rotating caps, auxiliary rotating shafts, and rotating column are connected by a belt. A protective shell is provided on the outer wall of the transition chamber. A motor is located inside the protective shell. An output gear is located on the output shaft of the motor, and the output gear meshes with the power gear.

[0013] Preferably, the upper end of the discharge pipe is provided with a transition chamber, and the aperture valve is located in the transition chamber.

[0014] Preferably, a loading bin is provided above the transition bin, the outer wall of the loading bin is provided with a feeding port, and the lower end of the loading bin is connected to the transition bin.

[0015] Preferably, the upper end of the loading hopper is provided with a cover plate, the top surface of the cover plate is provided with a motor, and the upper end of the agitation component passes through the cover plate and is connected to the output shaft of the motor.

[0016] Preferably, the side wall of the loading bin is provided with a feeding port.

[0017] Preferably, the agitation assembly includes a rotating rod, and the rotating rod is provided with helical blades.

[0018] Preferably, the lower end of the agitation component extends below the discharge pipe and is connected to a striking rod, which is used to disperse the material discharged from the discharge pipe.

[0019] Preferably, the diameter of the transition chamber is larger than the diameter of the lower end of the loading chamber, and the diameter of the discharge pipe is smaller than the diameter of the transition chamber.

[0020] Preferably, each of the rotating cap straps has a protrusion on its outer wall, and the belt passes through the protrusions in sequence, and the belt is connected to the rotating cap through the protrusions.

[0021] (III) Beneficial Effects

[0022] This invention provides a discharge pipe structure that is not easily clogged and facilitates diffusion. It has the following beneficial effects:

[0023] Before use, the refining slag is poured into the charging hopper through the feed inlet. Then, the hook of the lifting equipment is connected to the connecting lug. The device is then lifted so that the lower end of the discharge pipe is aligned with the slag inlet of the converter. The motor is then turned on, and the motor drives the output gear to rotate. When the output gear rotates, it drives the rotating column to rotate through the power gear. When the rotating column rotates, it pulls the belt. When the belt is pulled, it drives the baffle to rotate until the baffle no longer blocks the circular window. When the baffle no longer blocks the circular window, the refining slag will fall into the discharge pipe through the circular window. The refining slag passing through the discharge pipe will be agitated by the spiral blades. The refining slag agitated by the spiral blades will be dispersed. The dispersed refining slag will more easily mix with the molten steel in the ladle, increasing the bonding speed between the molten steel and the refining slag and preventing the refining slag from accumulating on the surface of the molten steel.

[0024] The discharge pipe structure, which is not prone to clogging and is easy to diffuse, has a through hole in the center of the aperture valve for passing through the agitator. This allows for the adjustment and control of the discharge amount without affecting the rotation of the agitator, and also prevents the discharge pipe from becoming clogged due to excessive discharge.
