Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum plate processing equipment, and in particular to a furnace flow sealing mechanism for aluminum plate processing. Background Technology
[0002] In the aluminum smelting industry, the smelting furnace is an important piece of equipment in the aluminum plate processing process. The furnace is equipped with flow holes and the outside is equipped with flow channels. The flow holes and the flow channels correspond to each other. After the metal melts from solid to liquid in the furnace, it flows into the flow channels through the flow holes and then flows to the designated location through the flow channels. When the flow holes are not in use, they need to be sealed with plugs to prevent the aluminum liquid from seeping out or flowing out. The sealing drive mechanism that drives the plugs in and out of the flow holes is the key mechanism to prevent the aluminum liquid from seeping out or flowing out.
[0003] A search revealed Chinese Patent Publication No. CN221571132U, which discloses a furnace flow hole sealing mechanism for aluminum plate processing. This mechanism employs a segmented sealing method, first moving the sealing rod to a horizontal working position, and then using a drive mechanism to horizontally push the sealing rod out and into the flow hole. This achieves reliable sealing while greatly simplifying the structural complexity. The driving force of the drive cylinder and drive mechanism ensures stable sealing between the sealing rod and the furnace, effectively preventing the sealing rod from loosening and aluminum leakage. This makes the entire device more stable and possesses the advantages of high efficiency and stability in flow blocking.
[0004] In actual use, the aforementioned sealing mechanism, when using a drive cylinder to move the plug to seal the flow hole, is prone to errors in the movement of the plug after long-term use. Excessive movement of the plug can cause squeezing and friction between the plug and the flow hole, easily damaging the plug and affecting its subsequent use. If the plug is not moved in place, it will lead to poor sealing and leakage. Therefore, a furnace flow hole sealing mechanism for aluminum plate processing is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1-2 One embodiment of this utility model is a furnace flow hole sealing mechanism for aluminum plate processing, including a furnace body 1 and a flow hole 2. A support frame 3 is fixedly connected to the right side surface of the furnace body 1. A swing arm 4 is provided on the front side of the support frame 3. An electric push rod 5 is fixedly connected to the bottom end of the swing arm 4. When the swing arm 4 is running, it can drive the electric push rod 5 to rotate. This is a prior art in the field and will not be described in detail here. A connecting plate 6 is fixedly connected to the left end of the electric push rod 5. When the electric push rod 5 is started, it can move the connecting plate 6 in a linear motion in the left and right directions.
[0034] Reference Figures 3-5 A heat insulation plate 7 is provided on the left side of the connecting plate 6. The heat insulation plate 7 has a hollow internal structure, utilizing the heat insulation properties of air to provide better heat insulation and reduce the conduction of heat from the left side of the heat insulation plate 7 to the right side. A connecting unit is provided on the right side of the heat insulation plate 7. The connecting unit includes a fixed cylinder 71, which is fixedly connected to the left side surface of the connecting plate 6. A movable cylinder 72 is provided inside the fixed cylinder 71, with its left end penetrating through the fixed cylinder 71. The movable cylinder 72 can move linearly left and right inside the fixed cylinder 71. The left end of the movable cylinder 72 is fixedly connected to the right side surface of the heat insulation plate 7. When the heat insulation plate 7 moves, it can drive the movable cylinder 72 to move synchronously. The right side of the movable cylinder 72 is fixedly connected to the outer side. A limiting ring plate 73 is connected, and the outer wall of the limiting ring plate 73 is in contact with the inner wall of the fixed cylinder 71. The limiting ring plate 73 limits the movement of the moving cylinder 72 and prevents the moving cylinder 72 from detaching from the fixed cylinder 71. A spring 74 is fixedly connected to the left inner wall surface of the moving cylinder 72, and the right end of the spring 74 is fixedly connected to the right inner wall surface of the fixed cylinder 71. When the moving cylinder 72 moves to the right, it will squeeze the spring 74, causing the spring 74 to compress and generate elastic potential energy. A plug 8 is fixedly connected to the left surface of the heat insulation plate 7. When the plug 8 moves, it can drive the heat insulation plate 7 to move synchronously. The size of the plug 8 is adapted to the size of the flow hole 2. When the plug 8 enters the flow hole 2, it can block the flow hole 2.
[0035] After the swing arm 4 drives the electric push rod 5 to rotate downwards to a horizontal position, the electric push rod 5 can be activated to move the connecting plate 6 to the left. At this time, the connecting plate 6 can drive the heat insulation plate 7 and the plug 8 to move to the left synchronously through the connecting unit. When the plug 8 moves to the left, it can enter the flow hole 2 to seal it. After the plug 8 enters the flow hole 2, the electric push rod 5 can be activated to move the connecting plate 6 to the left a certain distance. At this time, the plug 8 is limited and cannot move, which will then squeeze the heat insulation plate 7 and the moving cylinder 72, causing the moving cylinder 72 to move to the right and squeeze the spring 74. This will cause the spring 74 to compress and generate elastic potential energy. At this time, the elastic potential energy of the spring 74 can act on the plug 8, making the sealing of the flow hole 2 by the plug 8 more stable. When the electric push rod 5 causes errors in moving the plug 8 after long-term use, it can also be adjusted by the spring 74.
[0036] A guide unit is provided on the right side of the heat insulation plate 7. The guide unit includes a guide rod 91, which is fixedly connected to the right side surface of the heat insulation plate 7. A guide hole 92 is provided on the left side surface of the connecting plate 6. The right end of the guide rod 91 is inserted into the guide hole 92. The guide rod 91 can move linearly in the left and right directions inside the guide hole 92. The movement of the heat insulation plate 7 and the plug 8 can be guided and limited by the cooperation between the guide rod 91 and the guide hole 92, so as to prevent the plug 8 from shifting downward due to gravity after long-term use, which would affect the accuracy of sealing.
[0037] Reference Figure 6 A groove 10 is formed on the right side surface of the plug 8, and an electric heater 11 is fixedly connected to the left inner wall surface of the groove 10. The electric heater 11 can preheat the plug 8, so that the plug 8 maintains a certain temperature before entering the flow hole 2. This avoids the plug 8, which is at a low temperature, from coming into contact with the molten aluminum in the flow hole 2. The aluminum would then cool instantly and adhere to the plug 8, affecting its subsequent use. It also avoids the aluminum from cooling down when it comes into contact with the low-temperature plug 8. A vent hole 12 is formed on the inner wall surface of the groove 10, which penetrates the plug 8. The vent hole 12 allows the gas inside the groove 10 to exchange with the outside gas, preventing the gas inside the groove 10 from being squeezed by heat collision when the plug 8 is heated, thus affecting the service life of the plug 8.
[0038] Working principle: After the furnace body 1 is used, the swing arm 4 is started to drive the electric push rod 5 to rotate downward. When the electric push rod 5 reaches the horizontal state, the electric heater 11 is started to heat the plug 8, and the electric push rod 5 is started to drive the plug 8 to move to the left and enter the flow hole 2 for sealing. After the plug 8 enters the flow hole 2, the electric push rod 5 is started to drive the connecting plate 6 to move to the left, compressing the spring 74. This causes the spring 74 to generate elastic potential energy. Then, the movement of the plug 8 is adjusted by the continued compression or release of the spring 74. When the electric push rod 5 drives the plug 8 to move too much, the spring 74 can be compressed to adjust the elasticity and prevent the plug 8 from being damaged by excessive compression. When the electric push rod 5 drives the plug 8 to move but does not reach the preset position, the elastic potential energy generated by compressing the spring 74 can also act on the plug 8, so that the plug 8 can stably seal the flow hole 2.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
