Description

Technical Field

[0001] This application relates to the field of submerged sprue production technology, and in particular to a submerged sprue drying device. Background Technology

[0002] In continuous casting, the submerged entry nozzle is a key component for molten steel pouring, and its performance directly affects the flow stability of the molten steel and the quality of the cast billet. Current technologies for drying submerged entry nozzles are inefficient. Traditional air drying or asbestos felt wrapping and baking methods rely on natural ventilation or simple heating, resulting in long drying cycles and uneven heat distribution. This can easily lead to insufficient or overheating of the nozzle in certain areas, affecting the performance of the refractory material. Furthermore, existing equipment is inconvenient to operate, requiring frequent manual handling of the nozzle to the baking chamber, resulting in low automation. Additionally, the side holes are easily damaged by external forces during nozzle placement and removal. Summary of the Invention

[0003] The purpose of this application is to provide an immersion-type sprue drying device to solve the above-mentioned problems. Through a multi-layer material conveying structure, an automated loading and unloading system, and an optimized sealing design, it solves the problems of low efficiency, poor sealing, and cumbersome operation in the prior art, and realizes efficient, uniform, and continuous drying of immersion sprues. At the same time, it reduces energy consumption and safety risks, and has significant industrial application value.

[0004] This application achieves the above objectives through the following technical solutions:

[0005] An immersion-type sprue drying device includes: an electric furnace and multiple material conveying structures spaced apart along a vertical direction. The front of the electric furnace has a material inlet and outlet that avoids the material conveying structures. The material conveying structures include: a first baffle and a second baffle spaced apart to provide support; multiple support plates, each fixedly connected to the first baffle and the second baffle at both ends, and having notches evenly distributed along the length of the support plates; a cylinder bracket fixedly connected to the rear of the electric furnace; and a cylinder fixedly mounted on the cylinder bracket, with its output end fixedly connected to the second baffle. The cylinder is configured to drive the first baffle and the support plates to enter and exit the electric furnace through the material inlet and outlet.

[0006] In some embodiments, the system further includes: a chain conveyor capable of conveying submersible nozzles; a robotic arm disposed in front of the electric furnace; and grippers disposed at the end of the robotic arm to grip the submersible nozzles conveyed by the chain conveyor and then transfer them to a support pallet via the robotic arm.

[0007] In some embodiments, chain conveyors are provided on both sides of the electric furnace, and sprue support blocks are evenly spaced along the chain conveyors. The sprue support blocks are connected to pins of the chain conveyors, and sprue grooves adapted to immersion sprues are constructed on the sprue support blocks.

[0008] In some embodiments, the sprue support block is provided with two connecting ears, the chain of the chain conveyor is located between the connecting ears, and the connecting ears are provided with connecting holes adapted to the chain conveyor so as to be rotatably connected to the pin through the connecting holes.

[0009] In some embodiments, reinforcing ribs are provided on both sides of the support plate, and the two ends of the reinforcing ribs are fixedly connected to the first baffle and the second baffle.

[0010] In some embodiments, the support plate is configured with a receiving trough capable of accommodating the entire submersible nozzle.

[0011] Compared to existing technologies, this application features a multi-layer material conveying structure and an automated loading and unloading structure. The multi-layer support pallet design includes multiple material conveying structures (first baffle, second baffle, and support pallets) spaced vertically within the electric furnace, enabling simultaneous baking of multiple batches of immersion nozzles and significantly improving drying efficiency per unit time. The robotic arm and gripper work in tandem, utilizing an existing vision positioning system. The robotic arm can precisely grasp immersion nozzles from the chain conveyor and place them on the support pallet, achieving fully automated loading and unloading and avoiding damage to the nozzles caused by manual handling. For efficient continuous production and energy consumption control, a dual-chain conveyor design is employed: chain conveyors are installed on both sides of the electric furnace, using grooves on the nozzle support blocks (nozzle grooves) to ensure stable horizontal placement of the immersion nozzles, preventing rolling or displacement. The two conveyors are used for feeding and receiving materials respectively, forming a continuous operation process. Attached Figure Description

[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0020] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] like Figure 1-4 As shown, an immersion-type sprue drying device includes: an electric furnace 1 and multiple material conveying structures spaced apart along a vertical direction. The front of the electric furnace 1 has a material inlet / outlet 2 that avoids the material conveying structures. The material conveying structures include: a first baffle 3 and a second baffle 4 spaced apart, which can provide support; multiple support plates 5, each with its two ends fixedly connected to the first baffle 3 and the second baffle 4 respectively, and notches 6 uniformly constructed along the length of the support plates 5; a cylinder bracket 7, which is fixedly connected to the rear of the electric furnace 1; and a cylinder 8, which is fixedly mounted on the cylinder bracket 7 and whose output end is fixedly connected to the second baffle 4. The cylinder 8 is configured to drive the first baffle 3 and the support plates 5 to enter and exit the electric furnace 1 through the material inlet / outlet 2.

[0022] The electric furnace 1 in this embodiment is the prior art. In this application, the outlet is set as multiple material inlets and outlets 2. In some embodiments, the electric furnace 1 is a vacuum furnace. The first baffle 3 and the second baffle 4 can support the bearing plate 5. At the same time, the first baffle 3 can open and close the material inlets and outlets 2, and the second baffle 4 can close the opening through which the cylinder 8 output end passes through the electric furnace 1 to increase the sealing performance.

[0023] In some embodiments, the system further includes: a chain conveyor 9 capable of conveying immersion nozzles; a robotic arm 14 disposed in front of the electric furnace 1; and grippers 15 disposed at the end of the robotic arm 14, which are capable of gripping the immersion nozzles conveyed by the chain conveyor 9 and then transferring them to the support pallet 5 via the robotic arm 14.

[0024] In this embodiment, the chain conveyor 9, the robotic arm 14, and the gripper 15 are all existing technologies. The existing vision positioning system can locate the position of the immersion nozzle, thereby enabling the gripper 15 to accurately hold the immersion nozzle. The robotic arm 14 places the nozzle on the support plate 5 for loading. After drying, the immersion nozzle is placed on the chain conveyor 9 and transported away through the cooperation of the gripper 15 and the robotic arm 14, thus achieving automated drying.

[0025] In some embodiments, chain conveyors 9 are provided on both sides of the electric furnace 1, and sprue support blocks 10 are evenly spaced along the chain conveyors 9. The sprue support blocks 10 are connected to the chain conveyors 9 by pins, and the sprue support blocks 10 are constructed with sprue grooves 13 adapted to the immersion sprue.

[0026] The two-chain conveyor 9 in this embodiment can feed and receive materials to improve efficiency. The sprue groove 13 constructed on the sprue support block 10 can allow the submersible sprue to be placed horizontally on the sprue support block 10, while preventing the submersible sprue from rolling.

[0027] In some embodiments, the sprue support block 10 is provided with two connecting ears 11, the chain of the chain conveyor 9 is located between the connecting ears 11, and the connecting ears 11 are provided with connecting holes 12 adapted to the chain conveyor 9 so that they can be rotatably connected to the pin through the connecting holes 12.

[0028] In this embodiment, the connecting ear 11 is rotatably connected to the pin on the chain of the chain conveyor 9, which can avoid interfering with the cyclic transmission of the chain conveyor 9, and at the same time can follow the transmission of the chain conveyor 9 to transport the immersion nozzle.

[0029] In some embodiments, reinforcing ribs 16 are provided on both sides of the support plate 5, and the two ends of the reinforcing ribs 16 are fixedly connected to the first baffle 3 and the second baffle 4.

[0030] In this embodiment, the reinforcing rib 16 is fixedly connected to the first baffle 3 and the second baffle 4, further increasing the structural stability. At the same time, the reinforcing rib 16 slides with the material inlet / outlet 2, which can increase the movement stability when the supporting pallet 5 enters and exits the electric furnace 1.

[0031] In some embodiments, the support tray 5 is constructed with a receiving groove capable of accommodating the entire immersion nozzle, so that the support tray 5 completely supports the immersion nozzle, while the notch 6 on the support tray 5 allows heat to pass through, increasing the drying effect.

[0032] In the above structure, the multi-layer material conveying structure includes a support pallet 5 that can be driven by a cylinder 8 to move in and out. The robotic arm 14 and gripper 15 cooperate to pick up the immersion nozzle conveyed by one of the chain conveyors 9 and place it in the support pallet 5. After the material is loaded, the cylinder 8 drives the support pallet 5 into the electric furnace 1. The first baffle 3 and the second baffle 4 can close the material inlet and outlet 2. The electric furnace 1 starts drying the immersion nozzle. After drying, the immersion nozzle is sent out. The robotic arm 14 and gripper 15 cooperate to pick up the immersion nozzle and place it on another chain conveyor 9 for conveying. Repeating the above operation allows for continuous operation and improves drying efficiency.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application.
