Description

Technical Field

[0001] This utility model relates to the field of converter technology, and more specifically, to a novel converter. Background Technology

[0002] Steelmaking is a metallurgical process that involves heating pig iron or scrap steel to a molten state in a steelmaking furnace. By supplying oxygen or other oxidants, the carbon and other impurities (such as silicon, manganese, phosphorus, sulfur, etc.) are oxidized and removed, ultimately producing pure steel or alloy steel with specific compositions. A converter is a type of steelmaking furnace. Most existing steelmaking processes are completed using converters, which have advantages such as simple operation, stable structure, and good steelmaking effect.

[0003] The prior art discloses a novel converter with application number CN202221689043.1, which has only one furnace body. Since there are multiple types of steel, only one type of material can be steelred at a time. The smelting of multiple types of steel needs to be carried out sequentially. This operation method makes the working efficiency of this utility model low. At the same time, in order to ensure that the raw materials can fully contact oxygen during the steelmaking process, a pipeline structure is required to transport oxygen into the furnace body. Since the furnace body needs to be rotated, the pipeline structure inserted into the furnace body will hinder the rotational movement, reducing the practicality of this utility model.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

A lifting box is installed above the gantry frame, and multiple sets of shaft tubes pass through the lifting box via bearings. Multiple sets of air pumps are installed on the upper part of the lifting box, and connecting pipes are snapped onto the output ends of each air pump. One end of each connecting pipe is connected to the upper end of the shaft tubes via bearings. The upper part of the gantry frame... The gantry is equipped with multiple sets of rotating tubes through bearings, and each set of rotating tubes has two sets of slots on its inner wall. The lower ends of the multiple sets of shaft tubes slide through the interior of the multiple sets of rotating tubes. Each set of shaft tubes has two sets of clamping plates installed on its outer wall. Multiple sets of air jet holes are opened on the lower side wall of the multiple sets of shaft tubes.

[0010] Furthermore, a concave frame is installed on the upper part of the gantry frame, and an electric telescopic rod is fixedly inserted through the upper part of the concave frame. The telescopic end of the electric telescopic rod is fixedly connected to the upper part of the lifting box. Two sets of T-shaped rods slide through the upper part of the concave frame, and the lower ends of the two sets of T-shaped rods are fixedly connected to the upper part of the lifting box.

[0015] Furthermore, the lower ends of multiple sets of the shaft tubes are all sealed structures.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a novel converter with the following beneficial effects:

[0018] (1) This utility model adopts a connecting shaft and an installation shaft. In actual use of the new converter, steelmaking can be carried out inside multiple furnace bodies. When it is necessary to pour out various molten steels inside multiple furnace bodies, the control panel is used to make multiple sets of first self-locking forward and reverse motors work through the synchronous controller. The output ends of the multiple sets of first self-locking forward and reverse motors can drive multiple sets of main gears to rotate. Since multiple sets of main gears and multiple sets of driven gears mesh with each other, the rotating main gears can drive multiple sets of driven gears to rotate. The rotating multiple sets of driven gears can drive multiple sets of furnace bodies to rotate through multiple sets of connecting shafts and multiple sets of bearing mounting seats. When the interior of multiple furnace bodies is tilted, various molten steels inside can be poured out. After the various molten steels have been poured out, the controller is used to make the output ends of multiple sets of first self-locking forward and reverse motors rotate in the opposite direction through the synchronous controller. After the multiple sets of furnace bodies have been reset, steelmaking can continue. Through the set connecting shaft and installation shaft, steelmaking can be carried out on multiple types of steel at the same time, which improves the working efficiency of the new converter.

[0019] (2) This utility model uses a lifting box. As can be seen from the above operation, multiple furnace bodies can be used for steelmaking. Before this, the input ends of multiple air pumps can be connected to external oxygen tanks through pipes. Using the control panel, the multiple air pumps can be turned on, and the oxygen inside the oxygen tank can be filled into the interior of multiple shaft tubes through pipes and multiple connecting pipes. Finally, the oxygen can be ejected through multiple jet holes. At the same time, the control panel can be used to turn on the second self-locking forward and reverse motor. The output end of the second self-locking forward and reverse motor can drive the worm gear to rotate. Since the worm gear and multiple sets of sleeved gears interact with each other... The meshing, rotating worm gear can drive multiple sets of sleeved gears to rotate, and the rotating sets of sleeved gears can drive multiple sets of shaft tubes to rotate. When it is necessary to tilt multiple sets of furnace bodies, the electric telescopic rod can be shortened using the control panel, and multiple sets of shaft tubes can be moved upward through the lifting box. When the lower ends of multiple sets of shaft tubes are moved out of the interior of multiple sets of furnace bodies, multiple sets of furnace bodies can be tilted. Multiple sets of clamping plates, multiple sets of clamping slots, and two sets of T-shaped rods can ensure the stability of the lifting box's up and down movement. The lifting box can avoid the oxygen supply pipeline structure from affecting the rotation of the furnace body structure, thus improving the practicality of the new converter.

[0036] In one embodiment, the lower ends of the multiple sets of shaft tubes 7 are all sealed structures.

[0037] Working principle:

[0038] In actual use of the new converter, steelmaking can be carried out inside multiple furnace bodies 2. When it is necessary to pour out various types of molten steel from multiple furnace bodies 2, the control panel and the synchronous controller can be used to activate multiple sets of first self-locking forward and reverse motors 16. The output of the multiple sets of first self-locking forward and reverse motors 16 can drive multiple sets of main gears 17 to rotate. Since the multiple sets of main gears 17 mesh with multiple sets of driven gears 15, the rotating main gears 17 can drive the multiple sets of driven gears 15 to rotate. The rotating multiple sets of driven gears 15 can be driven by multiple sets of connecting shafts 4 and multiple sets of bearing mounting seats 3. When multiple furnace bodies 2 rotate and tilt internally, various molten steels can be poured out. After the molten steels have been poured out, the controller, through a synchronous controller, causes the outputs of multiple self-locking forward and reverse motors 16 to rotate in the opposite direction. After the multiple furnace bodies 2 have reset, steelmaking can continue. Through the connecting shaft 4 and mounting shaft 5, multiple types of steel can be steelmade simultaneously, improving the working efficiency of the new converter. Furthermore, as can be seen from the above operation, multiple furnace bodies 2 can perform steelmaking independently. Before this, multiple air pumps can be... The input end of pump 12 is connected to an external oxygen tank via a pipe. Using the control panel, multiple sets of air pumps 12 are activated, allowing oxygen from the oxygen tank to be pumped into multiple sets of shaft tubes 7 through pipes and multiple sets of connecting pipes 13. Finally, the oxygen is ejected through multiple sets of jet nozzles 10. Simultaneously, using the control panel, the second self-locking forward / reverse motor 21 is activated. The output end of the second self-locking forward / reverse motor 21 drives the worm gear 22 to rotate. Since the worm gear 22 meshes with multiple sets of sleeved gears 23, the rotating worm gear 22 drives the multiple sets of sleeved gears 23 to rotate. Multiple sets of sleeved gears 23 can drive multiple sets of shaft tubes 7 to rotate. When it is necessary to tilt multiple sets of furnace bodies 2, the electric telescopic rod 19 can be shortened using the control panel, and the multiple sets of shaft tubes 7 can be moved upward through the lifting box 6. When the lower ends of the multiple sets of shaft tubes 7 are moved out of the interior of the multiple sets of furnace bodies 2, the tilting operation of the multiple sets of furnace bodies 2 can be performed. Multiple sets of clamping plates 9, multiple sets of clamping slots 11 and two sets of T-shaped rods 20 can ensure the stability of the vertical movement of the lifting box 6. The lifting box 6 can avoid the oxygen pipeline structure from affecting the rotation of the furnace body structure, thus improving the practicality of the new converter.
