Description

Technical Field

[0001] The invention relates to the technical field of slag ditch waste heat recovery, and in particular to a blast furnace front slag ditch waste heat recovery device. Background Art

[0002] A blast furnace is constructed from steel plates lined with refractory bricks. The blast furnace itself is divided into five sections from top to bottom: the throat, body, waist, bosh, and hearth. Due to its excellent technical and economic performance, simple process, high production volume, high labor efficiency, and low energy consumption, blast furnace ironmaking accounts for the vast majority of global iron production.

[0003] The blast furnace needs to discharge slag during smelting. The slag ditch is a furnace-front container for collecting slag. When the slag is discharged into the slag ditch, it will carry some waste heat. The slag ditch will increase its own temperature under the influence of the waste heat of the slag, resulting in the slag stored in the slag ditch cooling more slowly. When the slag is discharged into the slag ditch, it will adhere to the inner wall of the slag ditch due to its own temperature, resulting in the slag solidifying on the inner wall of the slag ditch after cooling, making it very difficult to clean the slag.

[0020] The present invention has the following beneficial effects:

[0021] The heat radiation of the high-temperature molten slag or molten iron in the slag ditch of the present invention is transmitted to the interior of the heat-conducting black body material, and the heat-conducting black body material in turn conducts the heat to the heat exchange tube. The heat exchange tube transmits the heat to the interior of the gas collecting frame and discharges it through the connecting tube to complete the heat recovery. After the driving motor is powered on, the driving motor engages with the threaded rod through the gear. The threaded rod uses the rotation of the gear to push the separation component to move inside the slag ditch. The separation component is used to push the slag and the inner wall of the slag ditch to separate, so as to prevent the slag from being fixed inside the slag ditch after cooling, which makes the cleaning of the slag very inconvenient. A flow-pushing component is provided on the surface of the separation component. The flow-pushing component is used to push the slag to move toward the inner wall end of the slag ditch, so that the slag and iron can be separated from each other, so that the heat in the slag can quickly enter the interior of the heat-conducting black body material for recovery. The flow-pushing component is started by the movement of the separation component. The flow-pushing component generates gas when moving, so that the gas can push the heat in the slag to quickly enter the interior of the heat exchange tube for recycling.

[0022] The threaded rod of the present invention utilizes the connection with the threaded barrel to push the positioning plate to move inside the positioning hole when rotating, the connecting rod utilizes the movement of the positioning plate to push the vertical rod to move inside the slag groove, and the arc plate utilizes the movement of the vertical rod to push the slag to move inside the slag groove. After being pushed, the slag will be separated from the inner wall of the slag groove, avoiding the slag and the inner wall of the slag groove during cooling. The arc plate will push the slag to separate from each other when moving, so that the heat inside the slag can evaporate quickly and enter the interior of the heat exchange tube for recycling.

[0023] The vertical rod of the present invention pushes the spherical rod to move through the rectangular frame when it moves, and the spherical rod pushes the breaking block to move inside the slag groove through the positioning rod when it moves. The breaking block pushes the slag to move toward the end of the slag groove when it moves. When the slag is separated from the surface of the breaking block, the slag will slide downward using the curvature of the slag groove. The slag will separate from each other when it moves, so that the heat in the slag can quickly enter the interior of the shell for recovery, avoiding the accumulation of slag and the inability to completely volatilize the heat. After the breaking block pushes the slag to move away from each other, it pushes the slag to separate from the inner wall of the slag groove through the arc plate, thereby improving the working efficiency of the arc plate.

[0024] The circular hole column of the present invention utilizes the movement of the vertical rod to drive the extension frame to move. When the extension frame moves, it drives the support frame to move through the right-angle frame. The right-angle frame drives the meshing ring to move through the limit frame. The meshing ring drives the cylindrical rod to rotate by engaging with the tooth plate. The driving ring utilizes the rotation of the cylindrical rod to drive the groove ring to rotate inside the cylindrical frame. When the groove ring rotates, it drives the rotating rod to rotate through the cross. When the rotating rod rotates, it drives the fan blades to rotate and generates airflow. The airflow enters the interior of the slag iron through the groove column. At this time, when the airflow enters the interior of the heat exchange tube through the slag iron, it will bring heat into the interior of the heat exchange tube, thereby improving the efficiency of recycling the waste heat of the slag iron. The groove column is set on the surface of the cylindrical frame to prevent the slag iron from blocking the air outlet end of the cylindrical frame.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
