Description

Technical Field

[0001] The invention belongs to the technical field of ironmaking auxiliary equipment, and in particular relates to a blast furnace anhydrous taphole mud filling device. Background Art

[0002] The blast furnace casthouse is where the molten iron and slag, the final products of ironmaking, are discharged and collected. The casthouse is a hot, dusty environment, and the mud gun, used to block the taphole, needs to be loaded with mud before use. Blast furnaces tap iron frequently daily, and each loading involves 30 to 40 pieces of mud, each weighing 7 to 10 kg. Mud loading is mostly done manually, with the mud being carried piece by piece into the gun. This labor-intensive and costly process significantly limits loading efficiency. Furthermore, the harsh on-site environment poses safety risks for workers. Some casthouses currently utilize robots for automated mud loading, but this method places extremely high demands on incoming materials, requiring them to be of consistent specifications and neatly stacked. This necessitates increased investment in pre-incoming equipment and requires the raw materials to be processed before they can be transferred to the mud gun, resulting in prohibitive costs.

The two sides of the discharge channel are respectively a piston rod inlet and a taphole mud outlet. The telescopic rod is provided on one side of the hopper. The piston rod of the telescopic rod extends from the piston rod inlet into the discharge channel to push the taphole mud in the discharge channel out of the taphole mud outlet.

[0006] Furthermore, an oblique cut is cut downwardly at the taphole mud outlet to prevent the taphole mud from clogging the taphole mud outlet and to facilitate the falling of the taphole mud.

[0007] Furthermore, a protective sleeve is sleeved on the piston rod of the telescopic rod, and the protective sleeve is fixedly connected to the end of the piston rod of the telescopic rod to protect the piston rod on the telescopic rod.

[0008] Furthermore, a push rod is provided on the side wall of the silo, and the movable end of the push rod can be extended into the interior of the silo to facilitate breaking the arch when the cannon mud forms an accumulation.

[0009] Furthermore, a feeding cylinder is provided below the taphole mud outlet for directly conveying the taphole mud from the taphole mud outlet to the next process.

[0010] Furthermore, a receiving funnel is fixedly provided on the upper end of the feeding cylinder to better collect the fallen taphole mud.

[0011] Furthermore, the upper portion of the silo is rectangular, the middle portion is trapezoidal, and the lower portion is cylindrical, and the discharge channel is arranged in the cylindrical portion.

[0018] In order to further illustrate the technical solution of the present invention, the present invention is further described below through examples.

[0019] like Figure 1 、 Figure 2As shown, a blast furnace anhydrous taphole mud filling device includes a silo 1 and a telescopic rod 2. The upper part of the silo 1 is rectangular, the middle part is trapezoidal, and the lower part is cylindrical. A push rod 7 is provided on the side wall of the silo 1. The movable end of the push rod 7 can be extended into the interior of the silo 1 to facilitate breaking the arch when the taphole mud forms an accumulation. A discharge channel is provided on the cylindrical part of the silo 1. The two sides of the discharge channel are respectively a piston rod inlet 3 and a taphole mud outlet 4. An oblique cut 5 is cut downwardly at the taphole mud outlet 4. A feeding cylinder 8 is provided below the taphole mud outlet 4. A material receiving funnel 9 is fixedly provided at the upper end of the feeding cylinder 8, and the telescopic rod 2 is arranged on one side of the silo 1. The piston rod of the telescopic rod 2 extends from the piston rod inlet 3 into the discharge channel to push the cannon mud in the discharge channel out of the cannon mud outlet 4. A protective sleeve 6 is provided on the piston rod of the telescopic rod 2, and the protective sleeve 6 is fixedly connected to the end of the piston rod of the telescopic rod 2. The outer diameter of the protective sleeve 6 is 0-10mm smaller than the inner diameter of the discharge channel to protect the piston rod on the telescopic rod 2. The push rod 7 and the telescopic rod 2 are hydraulic telescopic rods, electric telescopic rods or pneumatic telescopic rods.

[0020] Working principle: When filling is required, the piston rod of the telescopic rod 2 is extended to push the cannon mud in the discharge channel below the silo 1 out of the cannon mud outlet 4 for filling. Then the piston rod of the telescopic rod 2 is retracted, and the cannon mud above the silo 1 falls down to refill the discharge channel. When the cannon mud in the silo 1 forms an arched accumulation, the piston rod of the push rod 7 is extended to break the arch of the cannon mud, causing the cannon mud to fall, so that the device can work normally.
