Description

Technical Field

[0001] The present invention relates to the technical field of aluminum liquid monitoring and alarm devices, and particularly to a leakage monitoring and alarm device for casting aluminum alloy round ingots. Background Art

[0002] When producing aluminum alloy round ingots, it is particularly important to use a mold for casting. Generally, dozens of billets are cast at one time, and in some cases, more than a hundred.

[0003] Currently, in the prior art, the monitoring of aluminum liquid leakage relies on manual observation of the flow change on the surface of the aluminum liquid to determine whether there is leakage. If dozens of billets are cast, manual observation is required repeatedly. This monitoring method is rather cumbersome. Moreover, when dozens of billets are formed simultaneously, if the mold at the rear leaks, it will be too late when the operator walks to the rear repeatedly in sequence. It is very difficult to be aware of the aluminum liquid leakage situation in the first place. At the same time, when dozens of billets are formed simultaneously and leakage occurs at the front and rear at the same time, it is very difficult for the operator to determine which mold is leaking in the first place, and thus it is impossible to adjust the leakage situation in the first place.

[0004] Combining the above problems, we will find that the existing leakage monitoring and alarm devices for casting aluminum alloy round ingots on the market are very difficult to avoid the above-mentioned problems simultaneously during use. And even if they can be solved, external tools need to be used in cooperation to solve them, thus unable to achieve the desired effect. Therefore, we propose a leakage monitoring and alarm device for casting aluminum alloy round ingots. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1.

When the molten aluminum drops from the leakage hole and the nylon rope breaks, the leakage of the molten aluminum can be monitored in a timely manner through physical phenomena.

[0021] 2. The present invention utilizes an alarm unit. When the nylon rope breaks, the reset spring loses its pulling force, causing the knocking head to strike the surface of the air duct. The knocking head corresponds to air ducts of different lengths, and different lengths of air ducts correspond to multiple sets of crystallizer bodies. Moreover, the internal air volumes of air ducts of different lengths are different, so the sounds emitted when being struck by the knocking head are different. It can determine which crystallizer body has a leakage phenomenon immediately when multiple sets of crystallizer bodies are working, thereby achieving the effect of precise alarm.

[0022] 3. The present invention utilizes a plugging mechanism. When molten aluminum leaks, the rotating disk tightens the plugging rope, then the plugging rope enters the inside of the plugging groove. Under the tension of the rotating disk, the plugging rope closely adheres to the inside of the plugging groove, thereby achieving plugging in the first time, preventing excessive outflow of molten aluminum, further expanding the remedial time, and at the same time, the plugging block can fill the gaps between the wound plugging ropes.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1: Please refer to Figures 1-9 , the present invention provides a technical solution: A leakage monitoring and alarm device for casting aluminum alloy round ingots, including a casting mechanism 1. The casting mechanism 1 includes a casting frame 11. A hydraulic cylinder 12 is fixedly connected to the bottom of the inner cavity of the casting frame 11. The output end of the hydraulic cylinder 12 is fixedly connected to a pushing frame 13. The top of the pushing frame 13 is fixedly connected to a dummy bar head body 15. A mould body 14 is installed on the top of the dummy bar head body 15. A graphite ring body 17 is arranged between the mould body 14 and the dummy bar head body 15. The mould body 14 is installed on the top of the inner cavity of the casting frame 11. A sealing groove 18 is arranged between the mould body 14 and the dummy bar head body 15. A monitoring and alarm mechanism 2 is arranged on the surface of the dummy bar head body 15;

[0035] The monitoring and alarm mechanism 2 includes a monitoring unit 21. The monitoring unit 21 is arranged on the surface of the dummy bar head body 15 and on the top of the pushing frame 13. The monitoring unit 21 is used to monitor whether there is a liquid leakage phenomenon between the mould body 14 and the dummy bar head body 15.

[0036] As a further limitation of the monitoring and alarm mechanism 2 of the present invention, the monitoring unit 21 includes a monitoring shell 2101 and an upper heat insulation cover 2102. The inside of the upper heat insulation cover 2102 is installed on the surface of the mold body 14 by bolts. A fixing frame 16 is installed at the bottom of the monitoring shell 2101 by bolts. One side of the fixing frame 16 is connected to the bottom of the dummy bar head body 15 by bolts, and the monitoring shell 2101 is installed on the surface of the dummy bar head body 15. A lower heat insulation cover 2103 is fixedly connected to the inner surface of the monitoring shell 2101, and the lower heat insulation cover 2103 fits on the surface of the dummy bar head body 15. A drainage tray 2104 is fixedly connected to the top of the inner cavity of the monitoring shell 2101. Leakage holes 2105 are formed in the inner cavity of the drainage tray 2104. One side of the monitoring shell 2101, the lower heat insulation cover 2103 and the drainage tray 2104 is arranged in an inclined plane, and the inclination angles are the same. Through the arrangement of the monitoring shell 2101 and the upper heat insulation cover 2102, the high temperature generated during the casting of the dummy bar head body 15 and the mold body 14 is blocked, thereby playing a protective effect. At the same time, the drainage tray 2104 is arranged in an inclined plane, so that the leaked molten aluminum can be smoothly drained into the inside of the leakage holes 2105. At the same time, the melting point of the nylon rope 2106 is between 200°C and 250°C. When the leaked molten aluminum drips onto the surface of the nylon rope 2106, it can break immediately, thereby realizing the monitoring effect;

[0037] A connecting frame 2108 is fixedly connected to the inner cavity of the monitoring shell 2101. The number of the connecting frames 2108 is set to be multiple, and they are distributed around the inside of the monitoring shell 2101. A guide wheel 2109 is movably connected to the top of the connecting frame 2108. The number of the guide wheels 2109 is set to be multiple. A guide groove 2107 is formed on the surface of the guide wheel 2109. A nylon rope 2106 is arranged inside the guide groove 2107. The nylon rope 2106 is sleeved on the surfaces of multiple guide wheels 2109. The nylon rope 2106 and the leakage holes 2105 are arranged in the same vertical plane. Through the arrangement of the connecting frame 2108, the position of the guide wheel 2109 is supported to prevent the guide wheel 2109 from shaking during work. Through the arrangement of the guide wheel 2109, the nylon rope 2106 is supported, thereby ensuring the tension of the nylon rope 2106. At the same time, the arrangement of the guide groove 2107 limits the position of the nylon rope 2106 to prevent the nylon rope 2106 from detaching from the inside of the guide wheel 2109.

[0038] The specific implementation manner of this embodiment is as follows: Through the fixing frame 16 at the bottom of the dummy bar head body 15, the monitoring shell 2101 is installed on the surface of the dummy bar head body 15. Subsequently, the upper heat insulation cover 2102 is installed on the surface of the mold body 14 through the bolts inside the upper heat insulation cover 2102. Then, the nylon rope 2106 is wound around and sleeved inside the guide groove 2107, and both ends of the nylon rope 2106 are wound around the surface of the positioning cylinder 2204. Subsequently, the working of the hydraulic cylinder 12 pushes the push frame 13 to move upward, and the push frame 13 drives the dummy bar head body 15 to extend into the inside of the mold body 14, from the attached Figure 5 As shown in the state, if the graphite ring body 17 is damaged or aged after long-term use, the molten aluminum flows out from the gap between the mold body 14 and the dummy bar head body 15, flows into the plugging groove 18, is diverted by the plugging groove 18 to the surfaces of the lower heat insulation cover 2103 and the monitoring shell 2101, and the molten aluminum is diverted to the surface of the drainage tray 2104 through the inclined surfaces of the monitoring shell 2101 and the lower heat insulation cover 2103. The molten aluminum is diverted to the leakage hole 2105 through the drainage tray 2104, and then the molten aluminum flows onto the surface of the nylon rope 2106 through the leakage hole 2105. At this time, the nylon rope 2106 breaks.

[0039] Embodiment 2: Please refer to Figures 1-9 , the present invention provides a technical solution: A leakage monitoring and alarm device for casting aluminum alloy round ingots. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The monitoring and alarm mechanism 2 further includes an alarm unit 22. The alarm unit 22 is divided into two sections, and one section is arranged in the monitoring unit 21, and the other section is arranged on one side of the casting frame 11. The alarm unit 22 is used for accurate alarm after leakage.

[0040] As a further limitation of the monitoring and alarming mechanism 2 of the present invention, the alarming unit 22 includes an L-shaped frame 2201 and a concave frame 2205. The concave frame 2205 is fixed inside the monitoring shell 2101. A reset seat 2210 is movably connected inside the concave frame 2205. Positioning cylinders 2204 are fixedly connected to the front side and the back side of the reset seat 2210. The positioning cylinders 2204 are used in cooperation with the nylon rope 2106. An adjusting screw column 2219 is threadedly connected to the inner cavity of the positioning cylinder 2204. One side of the adjusting screw column 2219 penetrates to one side of the positioning cylinder 2204 and is fixedly connected to a rotating plate 2218. The other side of the adjusting screw column 2219 is fixedly connected to a connecting column 2215. One side of the connecting column 2215 is movably connected to a pushing plate 2214 through a bearing. A positioning plate 2216 is fixedly connected to the bottom of the pushing plate 2214. One side of the positioning plate 2216 is in close contact with the surface of the nylon rope 2106. One end of the nylon rope 2106 is in close contact with the surface of the reset seat 2210. By the threaded connection of the adjusting screw column 2219 with the inside of the positioning cylinder 2204, when the adjusting screw column 2219 is rotated, it can cause the positioning plate 2216 to move, and then fix the two ends of the nylon rope 2106 through the movement of the positioning plate 2216, so that the nylon rope 2106 can be fixed on the surface of the positioning cylinder 2204;

[0041] One side of the reset seat 2210 is fixedly connected to two touch blocks 2206. A touch switch 2209 is arranged at the same horizontal position of the two touch blocks 2206. One side of the touch switch 2209 is fixed inside the concave frame 2205. Through the arrangement of the touch switch 2209 and the touch blocks 2206, when the reset seat 2210 resets and moves towards the touch switch 2209, it can cause the touch blocks 2206 to touch the touch switch 2209, and then trigger the servo motor 32 to work by the touch switch 2209 receiving a signal;

[0042] One side of the reset seat 2210 is fixedly connected with a reset rod 2207. The reset rod 2207 is located between two touch blocks 2206. A reset spring 2212 is sleeved on the surface of the reset rod 2207. One end of the reset spring 2212 is fixedly connected with one side of the reset seat 2210, and the other end of the reset spring 2212 is fixedly connected with the inside of the concave frame 2205. One side of the reset rod 2207 penetrates through one side of the concave frame 2205 and is movably connected with the inside of the concave frame 2205. One side of the reset rod 2207 is fixedly connected with a knocking head 2208. The knocking head 2208 is arranged in an arc surface structure. One side of the L-shaped frame 2201 is fixed to one side of the casting frame 11. Horizontal frames 2202 are fixedly connected to both the top and bottom inside the L-shaped frame 2201. An air duct 2203 is fixedly connected inside the horizontal frame 2202. The number of air ducts 2203 is multiple and they are arranged on the same horizontal plane as the knocking head 2208. The lengths of the multiple air ducts 2203 are different and are arranged from short to long. Through the setting of the reset spring 2212, after the position of the nylon rope 2106 is locked, the nylon rope 2106 is in a taut state, then the reset spring 2212 is stretched and deformed under force. When the nylon rope 2106 breaks, the reset spring 2212 recovers its deformation, and then it prompts the reset seat 2210 to move. Through the setting of the knocking head 2208, the surface of the air duct 2203 is knocked, so as to achieve the effect of alarming. At the same time, through the setting of the air duct 2203, the air ducts 2203 are set with different lengths, and the air ducts 2203 with different lengths correspond to multiple crystallizer bodies 14, which can judge which crystallizer body 14 has a leakage phenomenon in the first time when multiple crystallizer bodies 14 are working;

[0043] A horizontal groove 2217 is formed on the surface of the positioning cylinder 2204, and the surface of the push plate 2214 is movably connected with the inside of the horizontal groove 2217. Sliding blocks 2211 are fixedly connected to both the top and bottom of the reset seat 2210. Sliding grooves 2213 are formed on both the top and bottom of the inner cavity of the concave frame 2205, and the surface of the sliding block 2211 is slidably connected with the inside of the sliding groove 2213. Through the setting of the horizontal groove 2217, the friction between the positioning plate 2216 and the positioning cylinder 2204 is reduced, and then the positioning plate 2216 can slide smoothly inside the positioning cylinder 2204. Through the setting of the sliding groove 2213, the moving position of the sliding block 2211 is guided, and the stability of the reset seat 2210 during the moving process is further improved.

[0044] The specific implementation of this embodiment is as follows: Both ends of the nylon rope 2106 are sleeved on the surface of the positioning cylinder 2204, and the nylon rope 2106 is tightened. At this time, the reset seat 2210 moves to the left. The movement of the reset seat 2210 drives the reset rod 2207 to move, and the movement of the reset rod 2207 drives the percussion head 2208 to move. At the same time, the movement of the reset seat 2210 causes the reset spring 2212 to stretch and deform. Then, the rotating plate 2218 is rotated. The rotation of the rotating plate 2218 drives the adjusting stud 2219 to rotate. The rotation of the adjusting stud 2219 drives the connecting column 2215 to rotate on one side of the pushing plate 2214. Under the condition that the adjusting stud 2219 is threadedly connected to the positioning cylinder 2204, the adjusting stud 2219 moves into the interior of the positioning cylinder 2204. The movement of the adjusting stud 2219 drives the pushing plate 2214 to move. The movement of the pushing plate 2214 drives the positioning plate 2216 to move. The positioning plate 2216 slides inside the transverse groove 2217. The movement of the positioning plate 2216 fastens the tail end of the nylon rope 2106, so that the nylon rope 2106 can be in a tightened state and fixed on the surface of the positioning cylinder 2204. If the nylon rope 2106 breaks, the reset seat 2210 loses the tightening force. Under the condition that the reset spring 2212 restores deformation, the reset seat 2210 is urged to move to the right. The movement of the reset seat 2210 drives the reset rod 2207 to slide inside the concave frame 2205. The movement of the reset rod 2207 drives the percussion head 2208 to move. Then, the percussion head 2208 strikes the air duct 2203. The air ducts 2203 are set with different lengths and correspond to multiple sets of crystallizer bodies 14. When the percussion head 2208 strikes the air ducts 2203 with different lengths, different sounds can be emitted, so that the operator can judge which crystallizer body 14 has leaked in the first time, further improving the accuracy of the aluminum liquid leakage monitoring.

At the same time, the plugging rope 35 is a ceramic fiber rope, and the ceramic fiber rope can well withstand high temperatures, with a continuous service temperature up to 1000 °C and a short-term service temperature even up to 1260 °C. This characteristic enables it to maintain the structural stability and integrity in a high-temperature environment, and it is very suitable as a plugging material. At the same time, the ceramic fiber rope has good acid and alkali corrosion resistance and resistance to molten metal erosion, such as aluminum, zinc, etc. This characteristic enables it to maintain its performance in a corrosive environment and extends its service life, and then can fill and plug the plugging groove 18;

[0047] A positioning screw rod 38 is threadedly connected to the inner cavity of the rotating disk 33. The number of the positioning screw rods 38 is two.

The number of the elastic support members 36 is multiple, and the multiple elastic support members 36 are fixed to one side of the upper heat insulation cover 2102. Through the setting of the elastic support member 36, the position of the plugging rope 35 is supported, thus ensuring that the position of the plugging rope 35 does not shake.

[0049] The specific implementation of this embodiment is as follows: Insert the plugging rope 35 into the interiors of a plurality of elastic supports 36, and penetrate both ends of the plugging rope 35 into the interior of the slot 39. Then rotate the rotating plate 37. The rotation of the rotating plate 37 drives the positioning screw 38 to rotate. Under the threaded connection between the positioning screw 38 and the rotating disk 33, the positioning screw 38 moves towards the surface of the plugging rope 35. The movement of the positioning screw 38 drives the clamping plate 310 to move. The plugging rope 35 is fastened inside the slot 39 by the clamping plate 310. When the reset seat 2210 moves, it drives the touch block 2206 to move. When the touch block 2206 contacts the touch switch 2209, the touch switch 2209 receives the signal and transmits it to an external PLC controller. The external PLC controller controls the servo motor 32 to operate. The operation of the servo motor 32 drives the rotating disk 33 to rotate. The rotation of the rotating disk 33 drives the plugging rope 35 to wind. At this time, the plugging rope 35 is forced to break away from the interior of the elastic support 36 and is placed inside the plugging groove 18. When the plugging rope 35 winds into a twisted state, one side of the plugging rope 35 pulls the plugging block 34 to move, and the other side of the plugging block 34 fits the position of the plugging rope 35 on the other side. Then, the plugging block 34 plugs the crossing of the plugging ropes 35. At the same time, the plugging rope 35 closely adheres to the interior of the plugging groove 18 for temporary plugging, avoiding a large amount of molten aluminum leakage caused by the unknown situation at the first time.
