Description

Technical Field

[0001] This utility model relates to the technical field of slag cleaning tools, and in particular to a granulation tower slag and iron cleaning device. Background Technology

[0002] The blast furnace slag flushing system in steel enterprises generally adopts the environmentally friendly bottom filtration process. The main equipment for this method includes a granulation tower, slag flushing ditch, slag pool, slag grabbing crane, and slag transport vehicles. Among these, the granulation tower, as one of the core pieces of equipment, is typically constructed of welded steel, with a tower height reaching approximately 70 meters. It plays a crucial role in cooling, granulating, and transporting the high-temperature molten slag to subsequent processing systems. In actual production, when the blast furnace tapping conditions are unstable or abnormal, molten iron may enter the slag ditch along with the slag flow, and even enter the interior of the granulation tower, leading to iron accumulation. As the amount of accumulated iron increases, the internal space of the granulation tower gradually becomes limited, obstructing the slag flow channel, which in turn causes slag accumulation (commonly known as "full slag"). In severe cases, this will directly affect the normal slag discharge and production rhythm of the blast furnace, and may even force the blast furnace to shut down, resulting in significant economic losses and safety hazards.

[0003] Granulation towers are tall and constructed of integral welded steel. The presence of cleaning holes or iron discharge outlets at the bottom of the tower could compromise its structural integrity and stress balance, potentially leading to stress concentration, structural deformation, or even collapse – serious safety accidents. Therefore, the industry currently predominantly uses manual methods to clean the accumulated iron inside granulation towers, primarily employing simple lifting equipment such as hand-operated hoists. This method is not only labor-intensive and inefficient but also carries significant safety risks, failing to meet the demands of modern steel enterprises for efficient, safe, and environmentally friendly production. Utility Model Content

[0004] The purpose of this invention is to provide a granulation tower slag and iron cleaning device.

[0005] The technical solution to achieve the purpose of this utility model is: a slag and iron cleaning device for granulation tower, used for cleaning slag from the granulation tower. The granulation tower has a maintenance door in the middle, the maintenance door including a door frame and a door panel. The door frame is fixedly installed on the wall of the granulation tower. The first side of the door panel is hinged to the door frame, and the hinge axis of the door panel is perpendicular to the door frame. A notch is provided on the second side of the door panel, and the second side of the door panel and the first side of the door panel are opposite sides of the door panel. The slag and iron cleaning device for the granulation tower includes a guide rail, a vehicle body, and an electric hoist. The guide rail is horizontally fixed and passes through the notch in the door panel. The first end of the guide rail is located inside the granulation tower, and the second end of the guide rail is located outside the granulation tower. The diameter of the notch is determined by the opening and closing capability of the door panel. The vehicle body includes a frame and rollers. The rollers are rotatably mounted on the frame and roll on the guide rail. The electric hoist is mounted on the frame of the vehicle body.

[0006] Furthermore, the first end of the guide rail is fixed to the inner wall of the granulation tower. Since the guide rail is relatively long, fixing the first end of the guide rail to the inner wall of the granulation tower at a specific point has several advantages. First, the granulation tower serves as the final support carrier, eliminating the need for additional support carriers. Furthermore, the long length of the guide rail makes point-fixing simpler and more convenient. Second, fixing the first end of the guide rail to the inner wall of the granulation tower limits the travel of the first end of the guide rail, preventing the vehicle body from rolling off the first end of the guide rail.

[0007] Furthermore, a first support frame is fixedly installed on the inner wall of the granulation tower. The first support frame is located below the guide rail, and the first end of the guide rail is supported on the first support frame. Since the guide rail is relatively long, fixing the first end of the guide rail to the inner wall of the granulation tower would be difficult without support. With the first support frame provided in this invention, fixing the first end of the guide rail to the inner wall of the granulation tower without applying force is unnecessary, making the fixing operation more effortless and convenient.

[0008] Furthermore, the guide rail is welded and fixed to the first support frame. This arrangement further enhances the stability of the guide rail fixation.

[0009] Furthermore, the portion of the guide rail located at the door frame is welded and fixed to the door frame. This configuration achieves the fixation of the guide rail without the need for additional support structures, making the equipment simple and convenient.

[0010] Furthermore, a side beam is fixedly installed on the inner wall of the granulation tower. The side beam is located above and in contact with the guide rail. The side beam limits the guide rail from above, enhancing the stability of the guide rail.

[0011] Furthermore, the side beam is welded and fixed to the guide rail. This arrangement further enhances the robustness of the guide rail fixation.

[0012] Furthermore, a second support frame and a third support frame are fixedly installed on the inner wall of the granulation tower. One end of the side beam is supported on and welded to the second support frame, and the other end of the side beam is supported on and welded to the third support frame. The side beam lies horizontally above the guide rail, and its length is typically quite long. The second and third support frames provide support for the side beam, making the welding and fixing of the side beam to the inner wall of the granulation tower and to the guide rail easier and more convenient.

[0013] Furthermore, there are two side beams, one near the first end and the other near the second end of the guide rail. Since the guide rail is relatively long, when using the side beams to fix the guide rail from above, two side beams can be provided, one near the first end and the other near the second end of the guide rail, resulting in a more robust fixing structure.

[0014] Furthermore, the guide rail is made of I-beam steel. I-beam steel is readily available.

[0015] Furthermore, the rollers are provided in more than one set, each set comprising two wheels coaxially mounted, the two wheels respectively located in grooves on both sides of the guide rail formed by the I-beam. Preferably, the rollers are provided in two sets.

[0016] Furthermore, a limiting block is provided on the second end of the guide rail to prevent the vehicle body from rolling off the guide rail. This feature makes the operation of the vehicle body and the electric hoist on it more secure and reliable.

[0017] Furthermore, the upper surface of the guide rail is flush with the inner surface of the top of the door frame. The guide rail can be located in the middle of the door frame or at the top of the door frame. Compared to the former, the latter configuration has the advantages of a higher position, which reduces the impact on the maintenance door during operation and makes it more convenient. Furthermore, when the guide rail is made of I-beams, the fixing surface between the upper surface of the guide rail and the door frame is larger, resulting in a more robust fixing structure.

[0018] Furthermore, the notch is a right-angled notch.

[0019] Furthermore, a maintenance platform is provided outside the granulation tower, and the maintenance platform is located at the maintenance door. The provision of the maintenance platform facilitates work at the maintenance door.

[0020] Furthermore, the maintenance platform is fixedly installed on the outer wall of the granulation tower. The maintenance platform can be fixed to the outer wall of the granulation tower or to the ground. Since the granulation tower is relatively tall, fixing the maintenance platform to the outer wall of the granulation tower is more convenient.

[0021] Furthermore, the surface of the maintenance platform is flush with the inner surface of the bottom of the door frame. This avoids steps and facilitates work.

[0022] This utility model relates to a slag and iron cleaning device for granulation towers. By configuring a guide rail, a vehicle body, and an electric hoist, the electric hoist is mounted on the guide rail via the vehicle body. The guide rail provides support for the electric hoist, and the combination of the guide rail and the vehicle body allows for horizontal movement of the electric hoist. This enables not only the electric hoist to lift the slag and iron being cleaned from the granulation tower, but also the vehicle body to horizontally transport the cleaned slag and iron, thus achieving a complete lifting operation. The entire lifting operation requires minimal manual intervention. Compared to traditional manual lifting using a manual hoist, this method is time-saving, labor-saving, and more efficient. It also eliminates the need for manual operation from a height, enhancing operational safety.

[0023] In addition, the slag and iron cleaning device for the granulation tower of this utility model also has a notch on the second side of the door panel. The guide rail passes through the notch on the door panel. The notch is located on the side of the door panel away from the hinge with the door frame. The guide rail passing through the notch does not affect the opening and closing of the door panel. On this basis, the second end of the guide rail is located outside the granulation tower, so that the vehicle body and the electric hoist on it can be located inside or outside the granulation tower. This setting not only facilitates the removal of slag and iron during the slag cleaning process, but also allows the electric hoist to be moved out of the granulation tower when the slag and iron are not being cleaned, preventing the electric hoist from being corroded by water vapor inside the granulation tower and extending the service life of the electric hoist.

A notch 203 is provided on the second side 2022 of the door panel 202. The second side 2022 and the first side 2021 of the door panel 202 are opposite sides of the door panel 202. The slag and iron cleaning device for the granulation tower includes a guide rail 1, a vehicle body 2, and an electric hoist 3. The guide rail 1 is horizontally fixed and passes through the notch 203 on the door panel 202. The first end 11 of the guide rail 1 is located inside the granulation tower 10, and the second end 12 of the guide rail 1 is located outside the granulation tower 10. The diameter of the notch 203 is determined by the opening and closing capability of the door panel 202. The vehicle body 2 includes a frame 21 and rollers 22. The rollers 22 are rotatably mounted on the frame 21 and are rolled on the guide rail 1. The electric hoist 3 is mounted on the frame 21 of the vehicle body 2.

[0026] This utility model relates to a slag and iron cleaning device for granulation towers, used for cleaning the slag of the granulation tower 10. The granulation tower 10, as the core equipment of the blast furnace slag treatment system, is mainly used to rapidly cool and granulate high-temperature molten slag into recyclable water slag, while simultaneously achieving slag-water separation and water resource recycling. The maintenance door 20 located in the middle of the granulation tower 10 allows personnel to enter and exit during maintenance. The notch 203 on the second side 2022 of the door plate 202 is used to allow space for the guide rail 1.

[0027] This utility model relates to a slag and iron cleaning device for a granulation tower, comprising a guide rail 1, a vehicle body 2, and an electric hoist 3. The guide rail 1 serves as the track for the vehicle body 2 to run on; the vehicle body 2 provides the movement conditions for the electric hoist 3; and the electric hoist 3 serves as a lifting device for lifting slag from the granulation tower 10.

[0028] This utility model relates to a slag and iron cleaning device for granulation towers. When cleaning slag and iron from the granulation tower, the door panel 202 of the inspection door 20 is opened, and the electric hoist 3 is moved into the granulation tower 10. The slag and iron removed from the granulation tower 10 are hoisted by the electric hoist 3 and moved outside the granulation tower 10. During non-slag cleaning periods, the electric hoist 3 is moved outside the granulation tower 10 for storage.

[0029] This utility model relates to a slag and iron cleaning device for granulation towers. By configuring the guide rail 1, the vehicle body 2, and the electric hoist 3, the electric hoist 3 is mounted on the guide rail 1 via the vehicle body 2. The guide rail 1 provides support for the electric hoist 3, and the combination of the guide rail 1 and the vehicle body 2 also provides conditions for the electric hoist 3 to move horizontally. This allows for the simultaneous lifting of slag and iron from the granulation tower 10 using the electric hoist 3 and horizontal transfer of the cleaned slag and iron via the vehicle body 2, thus achieving a complete lifting operation. The entire lifting operation requires minimal manual intervention. Compared to traditional manual lifting using a manual hoist, this method is time-saving, labor-saving, and more efficient. Furthermore, it eliminates the need for manual operation from a height, enhancing operational safety.

[0030] In addition, the slag and iron cleaning device for the granulation tower of this utility model also has a notch 203 on the second side 2022 of the door plate 202. The guide rail 1 passes through the notch 203 on the door plate 202. The notch 203 is located on the side of the door plate 202 away from the hinge with the door frame 201. The guide rail 1 passing through the notch 203 does not affect the opening and closing of the door plate 202. On this basis, the second end 12 of the guide rail 1 is located outside the granulation tower 10, so that the vehicle body 2 and the electric hoist 3 on it can be located inside or outside the granulation tower 10. This setting not only facilitates the removal of slag and iron during the slag cleaning process, but also allows the electric hoist 3 to be moved out of the granulation tower 10 when the slag and iron are not being cleaned, preventing the electric hoist 3 from being corroded by water vapor inside the granulation tower 10 and extending the service life of the electric hoist 3.
