Description

Technical Field

[0001] This application relates to the field of electric arc furnace steelmaking technology, and in particular to an electric arc furnace weighing device with water cooling effect. Background Technology

[0002] Electric arc furnace (EAF) steelmaking is a steel production method that uses electricity as the primary energy source. Compared to traditional coal-based steelmaking methods, EAF steelmaking has several advantages, such as being more environmentally friendly, having a more controllable and flexible production process, and being more suitable for small-scale production. Among these advantages, accurate raw material input is crucial for ensuring the quality of the final product during EAF steelmaking.

[0003] The electric furnace weighing device mentioned in the existing Chinese patent (authorization announcement number: CN216206988U) can establish a weighing relationship between the weighing sensor and the object being weighed through the weighing bracket. The weighing sensor is installed inside the weighing bracket, which effectively protects the weighing sensor so that it only bears the force in the weighing direction. Other component forces generated by factors such as furnace tilting are transferred to the cradle platform by the weighing bracket, thereby protecting the weighing sensor. A cooling structure is set inside the weighing bracket above the weighing sensor to prevent heat from the furnace body from being transferred to the weighing sensor through the weighing bracket, thus avoiding affecting the weighing accuracy of the weighing sensor or even thermally damaging the weighing sensor.

[0004] In existing methods for weighing electric furnaces, most systems use a water pump to draw coolant from the tank into the weighing plate. The coolant absorbs heat from the weighing plate and then returns to the tank, creating a circulating water-cooled system to reduce the impact of high temperatures on the temperature sensor. However, over time and with increased usage frequency, the coolant gradually absorbs heat, causing the temperature in the tank to rise. As the temperature rises, the coolant becomes less effective at cooling the weighing plate, potentially leading to an increase in the temperature of the weighing sensor and affecting its sensitivity and accuracy. Utility Model Content

[0005] The purpose of this application is to provide a water-cooled electric furnace weighing device to address the problem that the cooling effect of the coolant on the weighing plate is relatively low as the temperature in the water tank gradually rises.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A water-cooled electric furnace weighing device includes a base, a bottom plate fixedly connected to the top of the base, a weighing sensor fixedly connected to the top of the bottom plate, a weighing plate disposed above the weighing sensor, an angle steel fixedly connected to the outer surface of the weighing plate, a protective cover fixedly connected to the inner side wall of the angle steel, the bottom of the protective cover fixedly connected to the bottom plate, the protective cover and the angle steel being fixed together by bolts, a placement block fixedly connected to the top of the weighing plate, and a water-cooling mechanism disposed on the top of the base.

[0007] By adopting the above technical solution, the furnace body is placed on the placement block. When the placement block is subjected to pressure, it will exert pressure on the weighing plate. The weighing plate will exert pressure on the weighing sensor, which will measure the weight of the object on the electric furnace and transmit this data to the weighing system for comparison. When the weighing plate is subjected to pressure, the angle steel can play a role in reinforcement and support, ensuring the stability and reliability of the weighing plate. The water cooling mechanism can absorb the temperature of the weighing plate and continuously reduce the temperature of the coolant in the water tank.

[0008] Furthermore, the water-cooling mechanism includes a water tank fixedly connected to the top of the base, a water pump fixedly connected to the top of the water tank, a water inlet end of the water pump penetrating the water tank and fixedly connected to a water pipe, the water pump being connected to the water pipe, a water outlet end of the water pump being fixedly connected to a water pipe, the water pump being connected to the water pipe, a heat dissipation groove is provided inside the weighing plate, a water pipe is fixedly connected inside the heat dissipation groove, both ends of the water pipe are penetrating the weighing plate, one end of the water pipe is fixedly connected to the water pipe, the water pipe is connected to the water pipe, the other end of the water pipe is fixedly connected to a water pipe, the water pipe is connected to the water pipe, the end of the water pipe away from the water pipe is fixedly connected to the water tank, the water pipe is connected to the water pipe, and a heat dissipation component is provided on the top of the water tank.

[0009] By adopting the above technical solution, the weighing plate can be continuously circulated and cooled by starting the water pump, which achieves the purpose of maintaining the stability of the temperature sensor and ensuring that its performance is within a suitable range, thus helping to improve the reliability and continuous working capability of the weighing sensor.

[0010] Furthermore, the water pipe is configured in an S-shape.

[0011] By adopting the above technical solution, the contact area between the water pipe and the heat dissipation groove is increased.

[0012] Furthermore, the heat dissipation component includes a cooling box fixedly connected to the bottom of the water tank. The cooling box has heat dissipation holes on both sides. A heat dissipation barrel is fixedly connected to the inner bottom wall of the water tank. The top of the heat dissipation barrel penetrates the cooling box and is open. A fan is fixedly connected to the inner bottom wall of the cooling box, and the blowing end of the fan is adapted to the heat dissipation holes.

[0013] By adopting the above technical solution, the heat sink is made of copper, which allows it to absorb heat. The top of the heat sink is also open, allowing the heat to be transferred to the cooling box. Then, the first fan is started, and the fan's blowing end is matched with the heat dissipation hole to draw outside air into the cooling box for heat exchange with the heat sink. This increases the heat exchange rate between the coolant and the outside air, thus ensuring that the coolant can continuously absorb heat.

[0014] Furthermore, a second fan is fixedly connected to the inner bottom wall of the refrigeration box, and the blowing end of the second fan is far away from the blowing end of the first fan.

[0015] By adopting the above technical solution, the heat exchange efficiency has been further improved.

[0016] Furthermore, positioning blocks are fixedly connected to the inner bottom walls on both sides of the refrigeration box, and a filter plate is slidably arranged on one side of the positioning block. The top of the filter plate passes through the refrigeration box and is fixedly connected to a handle. The filter plate is slidably arranged with the refrigeration box.

[0017] By adopting the above technical solutions, the risk of dust and other impurities entering the heat dissipation tank is reduced.

[0018] Furthermore, vertical plates are fixedly connected to both sides of the top of the refrigeration box, and threaded rods are threaded inside the vertical plates. A handle is fixedly connected to one end of the threaded rod, and the end of the threaded rod away from the handle passes through the vertical plate and is rotatably connected to an abutment plate. A rubber pad is fixedly connected to the side of the abutment plate away from the threaded rod.

[0019] By adopting the above technical solution, the stability of the filter plate during operation has been improved.

[0020] Furthermore, an auxiliary rod is fixedly connected to the side of the contact plate away from the rubber pad, and the end of the auxiliary rod away from the contact plate passes through the vertical plate, and the auxiliary rod is slidably connected to the vertical plate.

[0021] By adopting the above technical solution, the contact plate can be moved more smoothly.

[0022] In summary, this application includes at least one of the following beneficial effects; 1. In this application, after prolonged heat absorption, the fan is activated to draw outside air into the cooling box to exchange heat with the heat dissipation tank, thereby increasing the heat exchange rate between the coolant and the outside air. The flowing air carries away the temperature of the cooling water, allowing the coolant in the water tank to dissipate heat quickly. This ensures that the coolant remains in an effective heat absorption state during long-term operation of the electric furnace, maintaining the stable operation of the electric furnace.

[0023] 2. In this application, when heat dissipation is required for the weighing plate, the water pump works continuously to continuously circulate water cooling for the weighing plate, thereby achieving the purpose of maintaining the stability of the temperature sensor and ensuring that its performance is within a suitable range, which helps to improve the reliability and continuous working capability of the weighing sensor.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses a weighing device for an electric furnace with a water-cooling effect.

[0028] Reference Figure 1 and Figure 2A water-cooled electric furnace weighing device includes a base 1, a base plate 2 fixedly connected to the top of the base 1, a weighing sensor 3 fixedly connected to the top of the base plate 2, a weighing plate 4 above the weighing sensor 3, an angle steel 5 fixedly connected to the outer surface of the weighing plate 4, a protective cover 6 fixedly connected to the inner side wall of the angle steel 5, the bottom of the protective cover 6 fixedly connected to the base plate 2, and the protective cover 6 and the angle steel 5 fixedly connected by bolts 8. A placement block 7 is fixedly connected to the top of the weighing plate 4, and a water-cooling mechanism is provided on the top of the base 1.

[0029] When weighing the electric furnace, the furnace body is placed on the placement block 7. After the placement block 7 is subjected to pressure, the pressure is applied to the weighing plate 4. The weighing plate 4 then applies pressure to the weighing sensor 3, which measures the weight of the object on the electric furnace and transmits this data to the weighing system for comparison. When the weighing plate 4 is subjected to pressure, the angle steel 5 provides reinforcement and support, ensuring the stability and reliability of the weighing plate 4. During weighing, the water cooling mechanism absorbs the temperature of the weighing plate 4, reducing the impact of high temperature on the temperature sensor. At the same time, it continuously lowers the temperature of the coolant in the water tank 9, thereby maintaining the cooling effect of the coolant and ensuring the cooling effect during long-term use.

[0030] Reference Figures 2 to 4 The water cooling mechanism includes a water tank 9 fixedly connected to the top of the base 1. A water pump 10 is fixedly connected to the top of the water tank 9. The water inlet of the water pump 10 passes through the water tank 9 and is fixedly connected to a water pipe 11. The water pump 10 is connected to the water pipe 11. The water outlet of the water pump 10 is fixedly connected to a water pipe 12. The water pump 10 is connected to the water pipe 12. A heat dissipation groove 14 is opened inside the weighing plate 4. A water pipe 15 is fixedly connected inside the heat dissipation groove 14. Both ends of the water pipe 15 pass through the weighing plate 4. One end of the water pipe 15 is fixedly connected to the water pipe 2 12. The water pipe 2 12 is connected to the water pipe 15. The other end of the water pipe 15 is fixedly connected to a water pipe 16. The water pipe 15 is connected to the water pipe 16. The end of the water pipe 16 away from the water pipe 15 is fixedly connected to the water tank 9. The water pipe 16 is connected to the water pipe 3 15. A heat dissipation component is provided on the top of the water tank 9.

[0031] Among them, water pipe 315 is designed in an S-shape.

[0032] When heat dissipation is required for the symmetrical counterweight 4, the water pump 10 is first started. The water pump 10 draws the coolant from the water tank 9 into water pipe 11. As the water pump 10 continues to work, the coolant enters water pipe 12, which is connected to water pipe 15, allowing the coolant to flow in water pipe 15 and absorb the heat from the symmetrical counterweight 4. After the coolant has absorbed heat, it enters water pipe 16, which is connected to the water tank 9, completing the heat absorption process. The coolant then re-enters the water tank 9 for future use. The water pump 10 continuously circulates water to cool the weighing plate 4, maintaining the stability of the temperature sensor and ensuring its performance remains within a suitable range. This helps improve the reliability and continuous operation of the weighing sensor 3. When water flows in the water pipe 15, setting the water pipe 15 in an S-shape increases the contact area between the water pipe 15 and the heat dissipation groove 14, thereby improving heat exchange efficiency and more effectively reducing the temperature of the weighing plate 4.

[0033] Reference Figure 4 The heat dissipation component includes a cooling box 17 fixedly connected to the bottom of the water tank 9. The cooling box 17 has heat dissipation holes 29 on both sides. A heat dissipation barrel 18 is fixedly connected to the inner bottom wall of the water tank 9. The top of the heat dissipation barrel 18 passes through the cooling box 17 and is open. A fan 19 is fixedly connected to the inner bottom wall of the cooling box 17. The blowing end of the fan 19 is adapted to the heat dissipation holes 29.

[0034] A second fan 20 is fixedly connected to the inner bottom wall of the refrigeration box 17, and the blowing end of the second fan 20 is far away from the blowing end of the first fan 19.

[0035] After prolonged use, the cooling water in water tank 9 gradually heats up. The copper-material heat sink 18 absorbs the heat from the coolant. The open top of the heat sink 18 transfers the heat to the cooling chamber 17. Then, fan 19 is activated, its airflow end matching the heat dissipation hole 29, drawing outside air into the cooling chamber 17 for heat exchange with the heat sink 18. This increases the heat exchange rate between the coolant and the outside air. The flowing air carries away the heat from the cooling water, allowing for rapid heat dissipation from the water tank 9. This ensures that the coolant remains in an effective heat-absorbing state during prolonged operation, maintaining stable furnace operation. When cooling the coolant, fan 20 is activated, blowing heat from the cooling chamber 17 to the outside, further improving heat exchange efficiency.

[0036] Reference Figure 4 and Figure 5Positioning blocks 28 are fixedly connected to the inner bottom walls on both sides of the refrigeration box 17. A filter plate 21 is slidably arranged on one side of the positioning block 28. The top of the filter plate 21 passes through the refrigeration box 17 and is fixedly connected to a handle 22. The filter plate 21 is slidably arranged with the refrigeration box 17.

[0037] The top two sides of the refrigeration box 17 are fixedly connected to vertical plates 23. The internal threads of the vertical plates 23 are connected to threaded rods 24. One end of the threaded rods 24 is fixedly connected to a handle 22. The end of the threaded rods 24 away from the handles 22 passes through the vertical plates 23 and is rotatably connected to an abutment plate 25. The side of the abutment plate 25 away from the threaded rods 24 is fixedly connected to a rubber pad 26.

[0038] In addition, an auxiliary rod 27 is fixedly connected to the side of the contact plate 25 away from the rubber pad 26. The end of the auxiliary rod 27 away from the contact plate 25 passes through the vertical plate 23, and the auxiliary rod 27 is slidably connected to the vertical plate 23.

[0039] When cooling the refrigeration box 17, the air can be filtered by the filter plate 21, thereby reducing the risk of dust and other impurities entering the heat dissipation tank 18. By ensuring the continuous heat absorption capacity of the heat dissipation tank 18, after long-term use, the filter plate 21 can be removed for cleaning by pulling the handle 22. After cleaning, the filter plate 21 can be placed in the correct position by the positioning block 28. After the filter plate 21 is placed, the contact plate 25 is moved by rotating the threaded block, so that the contact plate 25 contacts the filter plate 21, thereby reducing the risk of displacement of the filter plate 21 during use and ensuring the stability of the filter plate 21 during operation. When the contact plate 25 moves, the auxiliary rod 27 provides an additional support point for the contact plate 25, so that the contact plate 25 moves smoothly.

[0040] Working principle: The furnace body is placed on the placement block 7. When the placement block 7 is under pressure, it applies pressure to the weighing plate 4. The weighing plate 4 applies pressure to the weighing sensor 3, which measures the weight of the object on the furnace and transmits this data to the weighing system for comparison. When the weighing plate 4 is under pressure, the angle steel 5 can provide reinforcement and support, ensuring the stability and reliability of the weighing plate 4. The water pump 10 draws the coolant from the water tank 9 into the water pipe 15. At this time, the coolant in the water pipe 15 begins to flow, thereby absorbing the heat of the weighing plate 4. After the heat absorption is completed, the coolant re-enters the water tank 9. With the continuous operation of the water pump 10, the weighing plate 4 can be continuously circulated and cooled.

[0041] By making the heat sink 18 out of copper, the heat sink 18 absorbs heat. The top of the heat sink 18 is open, so the heat in the heat sink 18 is transferred to the cooling box 17. Then, the fan 19 is turned on. The blower end of the fan 19 is matched with the heat dissipation hole 29, so that the outside air is drawn into the cooling box 17 to exchange heat with the heat sink 18, thereby increasing the heat exchange rate between the coolant and the outside air.
