Description

Technical Field

[0001] This utility model relates to the field of alloy production technology, specifically a furnace front sampling device for high-temperature alloy production. Background Technology

[0002] High-temperature alloy molten metal has a high density, and the spoon body is easily buoyed after contacting the liquid surface, causing traditional spoon bodies to float and making precise positioning difficult. If the entire device falls into the reactor, it will not only cause equipment damage and waste of raw materials, but may also cause safety accidents such as burns from high temperatures. At the same time, traditional sampling devices are time-consuming to remove the liquid, which cannot be done quickly, leading to the liquid reacting with the outside air and affecting the monitoring structure. Therefore, those skilled in the art have provided a furnace-front sampling device for high-temperature alloy production to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide a furnace front sampling device for high-temperature alloy production, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A furnace sampling device for high-temperature alloy production includes a storage tank. A bearing sealing plate is sealed at the upper edge of the inner wall of the storage tank. A neck is fixedly connected to the upper end of the bearing sealing plate. An extension rod is fixedly connected to the upper end of the neck. A fixed hook head is fixedly connected to the upper end of the extension rod. A snap-fit ​​assembly is provided at the lower end of the storage tank. A feeding assembly is provided in the storage tank through this snap-fit ​​assembly.

[0005] Furthermore, the snap-fit ​​assembly includes a snap-fit ​​plate and a sliding plate. A pair of opposing snap-fit ​​plates are fixedly connected to the lower end of the storage tank, and a sliding plate is snapped between the two adjacent snap-fit ​​plates. A pull ring is fixedly connected to the surface of the sliding plate.

[0006] Furthermore, the feeding assembly includes a rotating shaft, a rotating plate, and an anti-detachment plate. The rotating shaft is rotatably connected to the sliding plate, the rotating plate is fixedly connected to the surface of the rotating shaft, the anti-detachment plate is fixedly connected to the inner sidewall of the sliding plate, and one end of the rotating plate abuts against the anti-detachment plate.

[0007] Furthermore, the feeding assembly also includes a filling plate, which is fixedly connected to the inner sidewall of the sliding plate, with one end of the filling plate abutting against the rotating shaft.

[0008] Furthermore, the fixed hook head is provided with a hook groove for fixing an external hook.

[0009] Furthermore, the upper end of the bearing sealing plate is provided with a set of vent holes, and the vent holes are interconnected with the internal space of the storage tank.

[0010] By adopting the above technical solution Compared with the prior art, the beneficial effects of this utility model are: 1. When the device is lowered into the reactor through the fixed hook head and the external suspension equipment, and the bottom of the storage tank contacts the surface of the high-temperature alloy molten liquid, the continuous lowering process will drive the rotating shaft of the feeding component to rotate the rotating plate around the shaft. Compared with the traditional spoon-shaped feeding, it can effectively eliminate the buoyancy of the storage tank, thereby ensuring that the device will not fall into the reactor, and at the same time, it can allow the molten liquid to flow smoothly into the storage tank. 2. After the device is removed from the reactor, the bottom of the storage tank can be opened directly by using the snap-fit ​​assembly. Operators do not need tools; by pulling the pull ring on the sliding plate, the sliding plate can be disengaged from the pair of snap-fit ​​plates at the bottom of the storage tank, quickly opening the unloading channel at the bottom of the storage tank. This allows the high-temperature alloy molten liquid inside the tank to be poured directly into the testing container. This design greatly simplifies the unloading process, avoids the time-consuming disassembly that causes the molten liquid to cool and solidify (affecting subsequent testing), and reduces the contact time between the operator and the high-temperature tank wall, improving unloading safety.

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] Please see Figures 1-4 This utility model provides an embodiment of a furnace front sampling device for high-temperature alloy production, including a storage tank 6. A bearing sealing plate 4 is sealed at the upper edge of the inner side wall of the storage tank 6. A neck 3 is fixedly connected to the upper end of the bearing sealing plate 4. An extension rod 2 is fixedly connected to the upper end of the neck 3. A fixed hook head 1 is fixedly connected to the upper end of the extension rod 2. A snap-fit ​​assembly is provided at the lower end of the storage tank 6. A feeding assembly is provided in the storage tank 6 through this snap-fit ​​assembly.

[0014] In this embodiment, the snap-fit ​​assembly includes a snap-fit ​​plate 7 and a sliding plate 8. A pair of opposing snap-fit ​​plates 7 are fixedly connected to the lower end of the storage tank 6, and a sliding plate 8 is snapped between two adjacent snap-fit ​​plates 7. A pull ring 9 is fixedly connected to the surface of the sliding plate 8. The sliding plate 8 is aligned with the pair of opposing snap-fit ​​plates 7 at the lower end of the storage tank 6, and the sliding plate 8 is pushed horizontally between the two snap-fit ​​plates 7 until the sliding plate 8 completely covers the bottom opening of the storage tank 6, thus completing the snap-fit ​​fixation.

[0015] In this embodiment, the feeding assembly includes a rotating shaft 11, a rotating plate 12, and an anti-detachment plate 13. The rotating shaft 11 is rotatably connected to the sliding plate 8, and the rotating plate 12 is fixedly connected to the surface of the rotating shaft 11. The anti-detachment plate 13 is fixedly connected to the inner wall of the sliding plate 8, and one end of the rotating plate 12 abuts against the anti-detachment plate 13. The feeding assembly also includes a filling plate 10, which is fixedly connected to the inner wall of the sliding plate 8. One end of the filling plate 10 abuts against the rotating shaft 11. The fixing hook head 1 has a hook groove for fixing an external hook, and the upper end of the bearing sealing plate 4 has a... There is a set of vent holes 5, which are connected to the internal space of the storage tank 6. The operator controls the descent button of the suspension device to drive the device to slowly lower the tank, gradually bringing the storage tank 6 closer to the sampling port of the reactor. When the bottom of the storage tank 6 contacts the surface of the high-temperature alloy molten liquid, the molten liquid generates an upward buoyancy force on the storage tank 6. The operator continues to control the suspension device to continue lowering the tank. The bottom of the storage tank 6 is subjected to the reaction force of the molten liquid, which drives the rotating shaft 11 on the sliding plate 8 to rotate counterclockwise around the axis, thereby driving the rotating plate 12 to rotate synchronously, so that the feed port at the bottom of the storage tank 6 is fully opened. After the feed inlet is opened, the high-temperature alloy molten liquid flows smoothly into the storage tank 6 under the action of gravity. At the same time, the air in the storage tank 6 is compressed by the injection of molten liquid and is quickly discharged through the vent 5 at the upper end of the bearing sealing plate 4, so as to avoid the air pressure inside the tank rising and hindering the flow of molten liquid. After the sampling is completed, the operator controls the lifting button of the suspension equipment, and the drive device slowly lifts. As the device rises as a whole, the bottom of the storage tank 6 is separated from the surface of the molten liquid. Under the action of its own gravity and the pressure of the molten liquid inside the tank, the rotating plate 12 rotates clockwise around the rotating shaft 11, so that one end of it is tightly abutted against the anti-detachment plate 13. The system achieves automatic sealing of the inlet. The operator controls the suspension equipment to move the device to the pre-prepared unloading area, adjusts the height of the suspension equipment to ensure that the bottom of the storage tank 6 is at a suitable distance from the opening of the testing container, and keeps the storage tank 6 vertical. The operator stands outside the heat-insulating platform and uses the external space to clamp the pull ring 9 on the sliding plate 8, pulling the pull ring 9 outward in the horizontal direction. Under the action of the pulling force, the sliding plate 8 is smoothly pulled out from between the two clamping plates 7, and the unloading channel at the bottom of the storage tank 6 is fully opened. The high-temperature alloy melt in the tank is poured directly into the testing container under the action of gravity.

[0016] First, connect the device to the external suspension equipment and fix the hook through the hook groove of the fixed hook head 1 to ensure that the storage tank 6 is vertical. Control the suspension equipment to lower the device. When the bottom of the storage tank 6 contacts the surface of the molten liquid, continue to lower it. The storage tank 6 is subjected to the reaction force of the molten liquid, which drives the rotating shaft 11 to rotate the rotating plate 12 to open the feed port. Molten liquid flows in, and the air in the tank is discharged through the vent 5 to balance the air pressure. After being completely submerged, the rotating plate 12 returns to its original position by its own weight and the pressure of the molten liquid when it rises. It then abuts against the anti-detachment plate 13 to seal the feed port, and the filling plate 10 prevents leakage. Move the device to the unloading area. The operator pulls the sliding plate 8 and pulls the ring 9 to pull out the sliding plate 8 to open the unloading channel. The molten liquid is poured into the testing container. After unloading, push the sliding plate 8 back to its original position, clean the device, and the sampling is completed.

Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
