Description

Technical Field

[0001] This utility model relates to the field of temperature probe technology, and in particular to the installation structure of a temperature probe for a closed-loop circulating water branch of a submerged arc furnace. Background Technology

[0002] In the ferroalloy production process, critical components of the submerged arc furnace, such as the furnace body, furnace cover, and electrode holders, require cooling. These components utilize a closed-loop circulating water system, where water circulation effectively removes heat, ensuring stable operation of the equipment within a suitable temperature range. The cooled circulating water undergoes a specialized treatment process before being pumped back into the system for reuse, forming a highly efficient and environmentally friendly cooling cycle. To ensure cooling effectiveness and equipment safety, the circulating water temperature must be monitored in real time to adjust the water flow rate or cooling intensity as needed, guaranteeing the smooth operation of the entire production process.

[0003] Chinese patent document CN223192437U discloses an installation structure for a closed-loop circulating water branch temperature probe, relating to the field of temperature probe installation technology. The structure includes a housing and a base plate fixedly connected to the bottom of the housing. A torsion spring is fixedly connected to the top of a movable bolt, and a connecting rod is fixedly connected to the movable bolt. A limit rod is fixedly connected to the bottom of the connecting rod on the side away from the movable bolt. A support block is fixedly connected to the inner wall of the damping rod away from the housing. A detection probe is fixedly connected to the side of the fixed block away from the fixed column. In this invention, the damping rod is used to connect the fixed block, and the movable bolt, connecting rod, limit rod, and limit groove are interlocked to secure the detection probe. This avoids the problem of simply using screws to fix the temperature probe, which requires external tools for disassembly and replacement when damaged, making disassembly and replacement inconvenient when the temperature probe is damaged, and also inconvenient during installation and use.

[0004] While the aforementioned utility model facilitates the replacement of the temperature probe, it lacks a connection with the pipeline, resulting in an insufficiently secure connection. Furthermore, the lack of a fixed connection between the cover and the body makes the cover prone to sliding, exposing the internal components to the environment and making them susceptible to damage.

This utility model provides an installation structure for a temperature probe in a closed-loop circulating water branch of a submerged arc furnace. By setting up a fixing mechanism, the power transmission and direction change are achieved through the meshing transmission of a worm gear and a worm wheel. Then, the rotational motion is converted into linear motion through the cooperation of a gear and a toothed plate. Finally, the fixing block is precisely moved and tightly fitted with the box body, thereby firmly and stably fixing the box cover to the box body. This effectively resists external vibration and interference, avoids temperature measurement errors caused by probe position deviation, and provides a reliable guarantee for accurate monitoring of the temperature of the closed-loop circulating water branch of the submerged arc furnace, greatly improving the accuracy and reliability of the temperature measurement data.

Detailed Implementation

[0017] 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.

[0018] like Figure 1 - Figure 5 As shown, the installation structure of the temperature probe of the closed-loop circulating water branch of the electric arc furnace includes a box body 1, a box cover 2 installed on the upper part of the box body 1, a fixing mechanism 6 set inside the box cover 2, a processing module 11 set inside the box body 1, a probe 8 installed on the upper part of the processing module 11, the probe 8 is fixedly installed on the upper part of the box cover 2, a display screen 9 is installed on the outside of the box body 1, and a control panel 10 is installed on the side of the box body 1 located on the display screen 9. Mounting seat 1 3 is installed on the upper part of the cover 2. Mounting seat 2 4 is installed on the upper part of mounting seat 1 3. Mounting seat 1 3 is equipped with a disassembly and assembly mechanism 5. Rubber pads 7 are installed inside both mounting seat 1 3 and mounting seat 2 4.

[0019] It should be noted that the housing 1, as the foundation of the entire installation structure, provides installation space and protection for internal components such as the processing module 11 and probe 8, and also provides a mounting location for the display screen 9 and control panel 10. The cover 2 cooperates with the housing 1 to seal the housing 1 and prevent external interference with the internal components. Probe 8 is the core component for temperature measurement, directly contacting the closed-loop circulating water branch of the submerged arc furnace to sense temperature changes and convert them into electrical signals, which are then transmitted to the processing module 11. The processing module 11 receives the electrical signals from probe 8, amplifies, filters, performs analog-to-digital conversion, analyzes the data, and transmits the results to the display screen 9 for display. It can also control related equipment according to preset programs. The display screen 9 displays the temperature data processed by the processing module 11 in real time. The control panel 10 provides an operating interface for operators, allowing them to set temperature alarm thresholds, adjust parameters, and query historical data to control the temperature measurement installation structure.

[0020] Mounting base 3 provides an installation platform for mounting base 4 and related disassembly and assembly mechanisms 5, creating a stable installation environment for probe 8 together with mounting base 4. Mounting base 4 cooperates with mounting base 3 to facilitate the installation, maintenance, and replacement of probe 8. Rubber pads 7 are located inside mounting base 3 and mounting base 4 to buffer and reduce vibration, minimizing interference from external vibrations on probe 8 and ensuring accurate temperature measurement.

[0021] like Figure 4 As shown, the fixing mechanism 6 includes a worm 61, which is installed inside the cover 2. A worm wheel 62 is installed inside the cover 2. The worm 61 and the worm wheel 62 mesh with each other. Turntables 63 are installed at both ends of the worm 61, and a gear 64 is installed at the lower part of the worm wheel 62.

[0022] It should be noted that the worm 61 is the power input component of the fixing mechanism 6. It is driven to rotate by the turntable 63 and transmits power by meshing with the worm wheel 62. The worm wheel 62 meshes with the worm 61, receives its power, and transmits it to the gear 64, which can change the transmission direction and reduce the speed, making the fixing operation smoother and more precise. The turntable 63 is installed at both ends of the worm 61, providing a manual operation point for the operator to easily rotate the worm 61 to control the operation of the fixing mechanism 6.

[0023] like Figure 4 As shown, the inside of the box cover 2 is provided with a toothed plate 65, which meshes with a gear 64. A connecting plate 66 is installed at the end of the toothed plate 65 away from the gear 64. Multiple fixing blocks 67 are installed on the side of the connecting plate 66 away from the toothed plate 65. The outer periphery of the fixing blocks 67 is slidably connected to the upper part of the box body 1.

[0024] It should be noted that gear 64 receives power from worm gear 62 and drives toothed plate 65 to move, converting rotational motion into linear motion, providing power for the movement of fixed block 67. Toothed plate 65 meshes with gear 64, making linear motion and transmitting the motion to fixed block 67 through connecting plate 66. Connecting plate 66 connects toothed plate 65 and fixed block 67, and sliding column 68 provides guidance and support for the movement of connecting plate 66, ensuring smooth and accurate movement. Fixed block 67 slides towards or away from the box body 1 under the action of connecting plate 66, and when it is tightly engaged with box body 1, it can fix box lid 2 and box body 1.

[0025] like Figure 4 As shown, a sliding post 68 is provided at the end of the connecting plate 66 away from the fixing block 67, and the sliding post 68 is slidably connected to the inside of the box cover 2.

[0026] It should be noted that the sliding column 68 provides precise guidance for the movement of the connecting plate 66, restricts its movement trajectory, ensures the coordinated and accurate movement of each component of the fixing mechanism 6, and improves reliability and stability.

[0027] like Figure 5 As shown, the disassembly and assembly mechanism 5 includes a first connecting block 51 and a second connecting block 52. The first connecting block 51 is installed on the outside of the first mounting base 3, and the second connecting block 52 is installed on the outside of the second mounting base 4. A positioning block is provided on the upper part of the first connecting block 51, and the positioning block is slidably connected to the lower part of the second connecting block 52. A plug-in block 53 is provided on the lower part of the second connecting block 52, and the plug-in block 53 is installed inside the first connecting block 51.

[0028] It should be noted that connecting block 1 51 is connected to connecting block 2 52 via components such as positioning block and plug-in block 53, achieving a stable connection between mounting base 2 4 and mounting base 1 3. Connecting block 2 52 cooperates with connecting block 1 51, with initial positioning and guidance by the positioning block and insertion of the plug-in block 53 to achieve a secure connection. The positioning block provides initial positioning and guidance for connecting block 2 52, helping it to accurately align with connecting block 1 51. The insertion of the plug-in block 53 into connecting block 2 52 ensures a stable connection between the two, thereby fixing mounting base 2 4 and mounting base 1 3.

[0029] like Figure 5 As shown, the plug-in block 53 has two sliders 54 inside, and each slider 54 has a locking block 55 on its opposite side, and each slider 54 has a compression spring 56 on its opposite side.

[0030] It should be noted that when the plug block 53 is inserted into the connecting block 2 52, the slider 54 will be pressed by the locking block 55 and move. The locking block 55 cooperates with the internal slot of the connecting block 2 52 to realize the connection and locking of the plug block 53 and the connecting block 2 52, which facilitates the installation and disassembly of the mounting base 2 4 and the mounting base 1 3. The compression spring 1 56 can provide elastic force to the locking block 55, allowing the locking block 55 to automatically lock into the slot to achieve locking, ensuring a firm and reliable connection.

[0031] like Figure 5 As shown, a pressing plate 57 is provided inside the connecting block 51, and a pressing rod 58 is provided on the side of the pressing plate 57 away from the inside of the connecting block 51. A compression spring 59 is provided on the outer periphery of the pressing rod 58.

[0032] It should be noted that when disassembling mounting base 2 4, pressing the pressing rod 58 can push the pressing plate 57 to press the clamping block 55 out of the slot, thus separating the plug-in block 53 from the connecting block 2 52. The pressing rod 58 provides a pressing point for the operator; pressing it pushes the pressing plate 57 to move, and releasing it resets it under the action of the compression spring 2 59. The compression spring 2 59 provides a reset force, allowing the pressing rod 58 to automatically reset, ensuring that the disassembly and assembly mechanism 5 can be reused, and improving the convenience and reliability of operation.

[0033] The working principle of this utility model is as follows: The cover 2 is firmly fixed to the body 1 by the fixing mechanism 6, ensuring the relative position of the probe 8 and the body 1 is stable. The probe 8 senses the temperature change of the closed-loop circulating water branch of the electric arc furnace in real time and transmits the signal to the processing module 11 for processing. The processed data is displayed on the display screen 9, and the operator can perform relevant operations and settings through the control panel 10. When it is necessary to install or replace the probe 8, the installation and removal mechanism 5 can be used to conveniently and quickly install and remove the mounting base 2 4 and the mounting base 1 3, improving the maintenance efficiency of the equipment.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
