Description
Technical Field
[0001] This utility model relates to the field of weighing technology for smelting furnaces, specifically a weighing device for smelting furnaces. Background Technology
[0002] The weighing device is installed on the smelting furnace to measure the molten iron inside the furnace online and then calculate the weight.
[0003] According to the patent application published on the Internet (authorization announcement number: CN 220288180 U), "This utility model provides a weighing device for a smelting furnace, including a furnace body, a supporting rotating shaft on the furnace body, an attitude sensor on the furnace body, a weighing sensor in contact with the furnace body, a connecting block fixedly connected to the weighing sensor, a disassembly mechanism on the furnace body, a hydraulic cylinder on the furnace body, a connecting piece on the furnace body, and a power supply cabinet on the connecting piece. This solution, through the design of components such as a slot, a sliding rod, a connecting plate, a fixing block, a pull ring, and a connecting seat, allows the sliding rod to move out of the slot, and then the weighing sensor is pulled horizontally to move the connecting block out of the device, making the weighing sensor on the device easy to disassemble and maintain."
[0004] Regarding the above description, the applicant believes the following issues exist:
[0005] During use, the present invention facilitates the disassembly and maintenance of the weighing sensor by means of components such as the slot, slide bar, connecting plate, fixing block, pull ring, and connecting seat. However, in actual use, slag, dust, or acidic gases generated during the smelting process may corrode the sensor housing or connecting lines, shortening the equipment life. Furthermore, the scouring of the scale body or support structure by the high-temperature metal flow leads to a long-term decrease in accuracy, requiring frequent disassembly and maintenance of the weighing sensor, which increases the operating cost. Therefore, it is necessary to improve the weighing device for smelting furnaces to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a weighing device for a smelting furnace to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a weighing device for a smelting furnace, comprising a mounting base, a hydraulic rod fixedly mounted on the outer side of the mounting base, a smelting furnace body fixedly mounted on the top of the hydraulic rod, a weighing sensor body disposed on the top of the mounting base, a weighing mechanism disposed on the top of the mounting base, and a heat dissipation mechanism disposed on the top of the mounting base.
[0008] Preferably, the weighing mechanism includes a sealing shell, which is fixedly installed on the top of the mounting floor. A fixing frame is fixedly installed on the left side of the sealing shell, and a spring is fixedly installed inside the fixing frame. A sliding block is fixedly installed at the end of the spring away from the fixing frame, and a pull rope is fixedly installed inside the sliding block. A threaded frame is fixedly installed on the left side of the fixing frame, and a protective cover is threadedly installed on the outer side of the threaded frame. A wear-resistant liner is provided on the top of the sealing shell. After wear, only the wear-resistant liner is replaced instead of the entire structure, reducing maintenance costs.
[0009] Preferably, the sliding block is slidably installed inside the fixed frame, and the spring, sliding block and pull rope are provided in two sets, which are symmetrically distributed at the center line of the left side of the fixed frame, so as to facilitate the replacement of the wear-resistant liner.
[0010] Preferably, the wear-resistant liner has a slot at the corresponding position of the sliding block, and the sliding block is inserted into the slot. The threaded frame and protective cover are set on the outside of the pull rope. The weighing sensor body is set inside the sealed shell, and the top of the weighing sensor body is attached to the bottom of the wear-resistant liner to reduce the corrosion effect on the weighing sensor body and shorten the equipment life.
[0011] Preferably, the heat dissipation mechanism includes a water tank, which is fixedly installed on the top of the mounting floor. A heat-conducting block is fixedly installed inside the water tank, and a heat dissipation fin is fixedly installed on the right side of the heat-conducting block. A water pump is fixedly installed on the left side of the water tank, and an inlet pipe is fixedly installed on the left side of the water pump. A circulating water pipe is fixedly installed at the end of the inlet pipe away from the water pump, and a second water pump is fixedly installed at the end of the circulating water pipe away from the inlet pipe. This prevents the weighing sensor body from losing accuracy in a high-temperature environment, thereby ensuring the cooling effect on the weighing sensor body and avoiding accelerated material aging due to high temperatures.
[0012] Preferably, the heat-conducting block is located inside the water tank, the heat dissipation fins are located outside the water tank, and both water pump one and water pump two are fixedly installed to the water tank via connecting water pipes, utilizing the outside air to dissipate heat from the heat dissipation fins, thereby reducing the temperature of the water inside the water tank.
[0013] Preferably, the circulating water pipe is located on the outside of the weighing sensor body to facilitate heat dissipation of the weighing sensor body.
[0014] Compared with the prior art, this utility model provides a weighing device for a smelting furnace, which has the following advantages:
[0015] 1. The weighing device for this smelting furnace, through its weighing mechanism and the sealing shell, prevents slag, dust, or acidic gases generated during the smelting process from directly contacting the outer shell of the weighing sensor body, thereby reducing the corrosive effect on the weighing sensor body and shortening the equipment life. Furthermore, a wear-resistant liner is provided on the top of the weighing sensor body that is severely worn, allowing for easy replacement of the liner. After wear, only the wear-resistant liner is replaced, rather than the entire structure, reducing maintenance costs.
[0016] 2. The weighing device for the smelting furnace, through its heat dissipation mechanism, cools the inside of the sealed shell by circulating water through a water tank during operation. The heat-conducting block transfers the temperature of the water inside the tank to the outside through heat dissipation fins, utilizing the outside air to dissipate heat from the heat dissipation fins, thereby reducing the temperature of the water inside the tank. This facilitates heat dissipation for the weighing sensor body, preventing it from losing accuracy in high-temperature environments and ensuring the cooling effect on the weighing sensor body, thus avoiding accelerated material aging due to high temperatures.

[0025] Example 1:
[0026] Please see Figure 1-3 This utility model provides a technical solution: a weighing device for a smelting furnace, including a mounting base 1, a hydraulic rod 4 fixedly mounted on the outside of the mounting base 1, a smelting furnace body 5 fixedly mounted on the top of the hydraulic rod 4, a weighing sensor body 6 provided on the top of the mounting base 1, a weighing mechanism 2 provided on the top of the mounting base 1, and a heat dissipation mechanism 3 provided on the top of the mounting base 1.
[0027] Furthermore, the weighing mechanism 2 includes a sealing shell 21, which is fixedly installed on the top of the mounting floor 1. A fixing frame 22 is fixedly installed on the left side of the sealing shell 21. A spring 23 is fixedly installed inside the fixing frame 22. A sliding block 24 is fixedly installed at the end of the spring 23 away from the fixing frame 22. A pull rope 25 is fixedly installed inside the sliding block 24. A threaded frame 26 is fixedly installed on the left side of the fixing frame 22. A protective cover 27 is threaded on the outside of the threaded frame 26. A wear-resistant liner 28 is provided on the top of the sealing shell 21. After wear, only the wear-resistant liner 28 is replaced instead of the entire structure, reducing maintenance costs.
[0028] Furthermore, the sliding block 24 is slidably installed inside the fixed frame 22. The spring 23, the sliding block 24, and the pull rope 25 are provided in two sets and are symmetrically distributed at the center line of the left side of the fixed frame 22, which facilitates the replacement of the wear-resistant liner 28.
[0029] Furthermore, slots are provided at the corresponding positions of the wear-resistant liner 28 and the sliding block 24, and the sliding block 24 is inserted into the slot. The threaded frame 26 and the protective cover 27 are provided on the outside of the pull rope 25. The load cell body 6 is provided inside the sealing shell 21, and the top of the load cell body 6 is attached to the bottom of the wear-resistant liner 28 to reduce the corrosion effect on the load cell body 6 and shorten the equipment life.
[0030] Example 2:
[0031] Please see Figure 4 Furthermore, in conjunction with Embodiment 1, the heat dissipation mechanism 3 includes a water tank 31, which is fixedly installed on the top of the mounting floor 1. A heat-conducting block 32 is fixedly installed inside the water tank 31. A heat dissipation fin 33 is fixedly installed on the right side of the heat-conducting block 32. A water pump 34 is fixedly installed on the left side of the water tank 31. An inlet pipe 35 is fixedly installed on the left side of the water pump 34. A circulating water pipe 36 is fixedly installed at the end of the inlet pipe 35 away from the water pump 34. A water pump 37 is fixedly installed at the end of the circulating water pipe 36 away from the inlet pipe 35. This prevents the weighing sensor body 6 from losing accuracy in a high-temperature environment, thereby ensuring the cooling effect on the weighing sensor body 6 and avoiding accelerated material aging due to high temperature.
[0032] Furthermore, the heat-conducting block 32 is located inside the water tank 31, and the heat dissipation fins 33 are located outside the water tank 31. Water pump 1 34 and water pump 2 37 are both fixedly installed to the water tank 31 through connecting water pipes, using the outside air to dissipate heat from the heat dissipation fins 33, thereby reducing the temperature of the water inside the water tank 31.
[0033] Furthermore, the circulating water pipe 36 is located on the outside of the weighing sensor body 6 to facilitate heat dissipation of the weighing sensor body 6.
[0034] In actual operation, when this device is used, as the smelting furnace body 5 returns to the weighing platform, it first contacts the wear-resistant liner 28, squeezing the weighing sensor body 6, and then performs the weighing operation. Due to the wear-resistant liner 28, the pull rope 25 is pulled outward, and the pull rope 25 pulls the sliding block 24, causing the sliding block 24 to disengage from the insertion limit of the wear-resistant liner 28. After that, the wear-resistant liner 28 is removed. Through the setting of the sealing shell 21, the slag, dust or acidic gas generated during the smelting process does not directly contact the outer shell of the weighing sensor body 6, reducing the corrosive effect on the weighing sensor body 6 and shortening the equipment life. In addition, the wear-resistant liner 28 is set on the top of the severely worn weighing sensor body 6, which can protect it from wear. The wear liner 28 is replaced. After wear, only the wear-resistant liner 28 is replaced instead of the entire structure, reducing maintenance costs. Water pump 1 34 is started to cool the inside of the sealing shell 21 through the circulating water pipe 36. The water is then circulated back into the water tank 31 through water pump 2 37. The heat conduction block 32 transfers the temperature of the water inside the water tank 31 to the outside through the heat dissipation fins 33. The outside air is used to dissipate heat from the heat dissipation fins 33, thereby reducing the temperature of the water inside the water tank 31. This facilitates heat dissipation for the weighing sensor body 6, preventing the weighing sensor body 6 from losing accuracy in high-temperature environments. This ensures the cooling effect of the weighing sensor body 6 and avoids accelerated material aging due to high temperatures.
