Description
Technical Field
[0001] This invention relates to the field of heating equipment technology, specifically to an electrothermal silicon molybdenum rod with a base plate. Background Technology
[0002] Heating equipment plays a vital role in many fields such as modern industrial production and scientific research experiments. With the continuous progress of science and technology and the vigorous development of industry, higher and higher requirements are put forward for the performance and adaptability of heating equipment. As a common and efficient heating element, electrothermal silicon molybdenum rod has been widely used in industries such as metallurgy, glass manufacturing, ceramic firing and electronic semiconductor processing due to its excellent characteristics such as high temperature resistance, oxidation resistance and high heating efficiency.
[0003] When an electric heating silicon molybdenum rod is in use, the rod generates heat due to its own resistance characteristics after current passes through it, thus achieving the heating function. The design with a base plate provides better support and fixation for the silicon molybdenum rod, ensuring its stable position in the heating equipment. Currently, in practical applications, existing electric heating silicon molybdenum rods on the market are fixed to the heating equipment by bolts or welding, and then the silicon molybdenum rod is threaded onto the base plate to ensure its stability.
[0004] The above-mentioned solutions have some problems. In scenarios where frequent adjustments to the heating position or the height of the heating element need to be adjusted according to different processing techniques, this fixed installation method is difficult to meet the requirements. Moreover, the angle adjustment function of existing electrothermal silicon molybdenum rods is also relatively limited. In actual heating processes, due to differences in the shape, structure, and heating process of the heated object, the electrothermal silicon molybdenum rod often needs to be heated at different angles to achieve uniform heating and efficient heat transfer. However, existing electrothermal silicon molybdenum rods are difficult to flexibly adjust to multiple angles. This results in the inability to achieve ideal heating effects when heating some irregularly shaped objects or objects with high requirements for heating uniformity, affecting product quality and production efficiency. In addition, regarding the connection between the electrothermal silicon molybdenum rod and the mounting components, the existing connection structure is easily affected by the thermal expansion and contraction of the electrothermal silicon molybdenum rod when used in a long-term high-temperature environment. Repeated thermal stress can cause problems such as loosening and breakage at the connection points, which not only shortens the service life of the electrothermal silicon molybdenum rod and the connection structure and increases equipment maintenance costs, but may also cause malfunctions in the heating equipment during operation, affecting the continuity and stability of production. Therefore, we propose an electrothermal silicon molybdenum rod with a base plate. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide an electrothermal silicon molybdenum rod with a base plate, which can flexibly adapt to different working scenarios and the connecting components can buffer thermal stress, thus effectively solving the problems in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrothermal silicon molybdenum rod with a base plate, comprising an electrothermal silicon molybdenum rod, wherein the input end of the electrothermal silicon molybdenum rod is electrically connected to an external power supply, and further comprising a base plate and an adjustment assembly;
[0007] Base plate: It includes a base, slide rails, slide plates and mounting base. The upper side of the base is provided with evenly distributed slide rails, and the lower side of the mounting base is provided with evenly distributed slide plates. The slide plates are all slidably connected to the interior of the adjacent slide rails on the lower side.
[0008] Adjustment component: It includes a mounting rod, and the upper end of the mounting base is provided with an adjustable mounting rod. The mounting rod and the electrothermal silicon molybdenum rod are installed together through a connecting component. It has height and angle adjustment functions, which can flexibly adapt to different working scenarios. The connecting component can buffer thermal stress, extend the service life of the silicon molybdenum rod and the connecting structure, and reduce equipment maintenance costs.
[0009] Furthermore, the base plate also includes slots and pins. The middle of the slide rail and the slide plate are provided with evenly distributed slots, and the upper end of the base is provided with evenly distributed pins. The pins are installed in conjunction with adjacent slots to adjust the height.
[0010] Furthermore, the adjustment assembly includes a bearing, a mounting plate, a vertical plate, and a rotating shaft. The mounting base has a rotating hole in the middle, and a bearing is installed inside the rotating hole. The inner wall of the bearing's inner ring is provided with a mounting plate. The upper side of the mounting plate is provided with symmetrically distributed vertical plates. A rotating shaft is provided between the two vertical plates. A mounting rod is fixedly connected to the middle of the rotating shaft to facilitate the adjustment of the tilt angle.
[0011] Furthermore, the adjustment assembly also includes a limiting barrel, which is fixedly connected to the rear side of the front upright plate. The front end of the rotating shaft is located inside the limiting barrel, and a tightening screw is threaded to the right end of the outer arc surface of the limiting barrel. The tightening screw is configured to cooperate with the rotating shaft.
[0012] Furthermore, the adjustment assembly also includes a rotating wheel, which is mounted on the upper side of the mounting plate via a mounting bracket, facilitating the adjustment of the circumferential angle.
[0013] Furthermore, the adjustment assembly also includes a limiting post and a limiting hole. The right end of the rotating wheel is provided with a limiting plate, and the right end of the limiting plate is slidably connected to the limiting post. The upper side of the mounting base is provided with evenly distributed limiting holes, and the lower end of the limiting post is inserted into the adjacent limiting hole on the lower side to limit the circumferential angle after adjustment.
[0014] Furthermore, the connecting assembly includes a connecting block, a threaded hole, a high-temperature resistant metal shell, and an inlay groove. The upper end of the mounting rod has an inlay groove, the interior of which is fitted with a high-temperature resistant metal shell. The interior of the high-temperature resistant metal shell has a connecting block, and the middle of the connecting block has a threaded hole. The threaded hole is threadedly connected to the lower end of the electrothermal silicon molybdenum rod, which significantly extends the service life of the silicon molybdenum rod and the connecting structure.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This electrothermal silicon molybdenum rod with a base plate has the following advantages:
[0016] 1. This electrothermal silicon molybdenum rod features height adjustment. By pushing the mounting base, the sliding plate moves within the slide rail, and the pin and slot fix its position. This allows for convenient and precise adjustment of the rod's height according to actual usage needs, solving the problem of fixed installation positions and limited flexibility in traditional electrothermal silicon molybdenum rods. This significantly improves the equipment's applicability in different working scenarios, ensuring it can be installed in the optimal heating position and enhancing heating efficiency.
[0017] 2. This electrothermal silicon molybdenum rod also has an angle adjustment function. By rotating the shaft, the mounting rod and the electrothermal silicon molybdenum rod can be rotated. After adjusting to the appropriate position, it can be fixed with the tightening screw to initially determine the angle of the electrothermal silicon molybdenum rod. Then, by rotating the wheel, the mounting plate, the vertical plate, the shaft and the mounting rod can be rotated around the bearing to further change the angle of the electrothermal silicon molybdenum rod. It is then locked with the limiting post and the limiting hole, realizing the precise adjustment of the electrothermal silicon molybdenum rod at multiple angles, meeting various complex heating angle requirements, and improving the uniformity and targeting of heating.
[0018] 3. When assembling this electrothermal silicon molybdenum rod with the base plate, a high-temperature resistant metal shell is embedded in the mounting groove of the mounting rod, and a graphite fiber reinforced flexible ceramic connecting block is used. On the one hand, this enhances the connection stability between the electrothermal silicon molybdenum rod and the mounting rod. On the other hand, when the electrothermal silicon molybdenum rod undergoes dimensional changes due to thermal expansion and contraction, the high-temperature resistant metal shell and the connecting block can effectively buffer thermal stress through their own elastic deformation, preventing problems such as loosening and breakage at the connection due to stress concentration. This significantly extends the service life of the silicon molybdenum rod and the connection structure, reduces equipment maintenance costs, and improves the long-term operational reliability of the equipment.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Please see Figure 1-4 This embodiment provides a technical solution: an electrothermal silicon molybdenum rod with a base plate, including an electrothermal silicon molybdenum rod 4, the input end of the electrothermal silicon molybdenum rod 4 being electrically connected to an external power supply, and also including a base plate 1 and an adjustment component 2;
[0026] Base plate 1: It includes a base 11, slide rails 12, slide plates 15, and mounting base 16. The upper side of the base 11 is provided with evenly distributed slide rails 12, and the lower side of the mounting base 16 is provided with evenly distributed slide plates 15. Each slide plate 15 is slidably connected to the adjacent slide rail 12 on its lower side. The base plate 1 also includes slots 13 and pins 14. Evenly distributed slots 13 are provided in the middle of both the slide rails 12 and the slide plates 15. Evenly distributed pins 14 are provided at the upper end of the base 11, and each pin 14 engages with an adjacent slot 13 for installation. The base plate 1 is welded to the working position. When it is necessary to adjust the electrothermal silicon molybdenum rod 4 at a high temperature... When the slide plate 15 is slidably connected to the slide rail 12, the mounting base 16 can be pushed to make the slide plate 15 slide in the slide rail 12. After reaching the appropriate position, the pin 14 is inserted between the slot 13 of the slide plate 15 and the slot 13 parallel to the slide rail 12 (there will be multiple sets of parallel slots 13, and workers can prepare multiple pins 14 to insert into them) to fix the position of the mounting base 16. This allows for flexible adjustment of the horizontal position of the electrothermal silicon molybdenum rod 4 according to actual usage requirements. It can adjust the height of the electrothermal silicon molybdenum rod 4 while providing better support and fixation for the electrothermal silicon molybdenum rod 4, so that the electrothermal silicon molybdenum rod 4 maintains a stable position in the heating equipment.
[0027] Adjustment component 2 includes a mounting rod 25. The upper end of the mounting base 16 has an adjustable mounting rod 25. The adjustment component 2 includes a bearing 21, a mounting plate 22, a vertical plate 23, and a rotating shaft 24. A rotating hole is formed in the center of the mounting base 16, and a bearing 21 is installed inside the rotating hole (the inner arc surface of the rotating hole is fixedly connected to the outer arc surface of the outer ring of the bearing 21). The inner wall of the inner ring of the bearing 21 is provided with the mounting plate 22 (the inner arc surface of the inner ring of the bearing 21 is fixedly connected to the outer arc surface of the mounting plate 22). Symmetrically distributed vertical plates 23 are provided on the upper side of the mounting plate 22. A rotating shaft 24 is provided between the two vertical plates 23, and the mounting rod 25 is fixedly connected to the center of the rotating shaft 24. The adjustment component 2 also includes a limiting barrel 26, which is fixedly connected to the rear side of the front vertical plate 23. The rotating shaft 24... The front end is located inside the limiting barrel 26. The right end of the outer arc surface of the limiting barrel 26 is threaded with a tightening screw 261. The tightening screw 261 is set to cooperate with the rotating shaft 24. The adjusting component 2 also includes a rotating wheel 27. The rotating wheel 27 is mounted on the upper side of the mounting plate 22 through the mounting bracket. The adjusting component 2 also includes a limiting post 28 and a limiting hole 29. The right end of the rotating wheel 27 is provided with a limiting plate 271. The right end of the limiting plate 271 is slidably connected to the limiting post 28. The upper side of the mounting base 16 is provided with evenly distributed limiting holes 29. The lower end of the limiting post 28 is inserted into the adjacent limiting hole 29 on the lower side. The rotating shaft 24 is rotated according to the usage requirements. The rotation of the rotating shaft 24 drives the mounting rod 25 to rotate synchronously. At this time, the mounting rod 25 drives the electrothermal silicon molybdenum rod 4 to rotate through the connecting component 3. When the electrothermal molybdenum rod 4 rotates to the appropriate position, the tightening screw 261 can be tightened to block the rotating shaft 24, preventing the rotating shaft 24 from rotating accidentally and ensuring the angle of the electrothermal molybdenum rod 4 is stable. Then, the rotating wheel 27 is rotated, which drives the mounting plate 22 to rotate around the bearing 21. The upright plate 23 on the mounting plate 22, the rotating shaft 24, and the mounting rod 25 rotate accordingly, thereby changing the angle of the electrothermal molybdenum rod 4. After adjusting to the appropriate angle, the limiting post 28 is inserted into the corresponding limiting hole 29 to limit the rotation of the rotating wheel 27. The above steps complete the adjustment of the angle of the electrothermal molybdenum rod 4, which facilitates the adjustment of the angle of the electrothermal molybdenum rod 4. The mounting rod 25 and the electrothermal molybdenum rod 4 are installed together through the connecting component 3. The connecting component 3 includes a connecting block 31, a threaded hole 32, and a high-temperature resistant metal shell 33. The mounting rod 25 has an inlay groove 34 at its upper end. A high-temperature resistant metal shell 33 (a molybdenum alloy shell) is fitted inside the inlay groove 34. A connecting block 31 (a graphite fiber reinforced flexible ceramic connecting block) is located inside the high-temperature resistant metal shell 33. A threaded hole 32 is located in the middle of the connecting block 31, and the threaded hole 32 is threaded to the lower end of the electrothermal silicon molybdenum rod 4. When installing the electrothermal silicon molybdenum rod 4, the lower end of the electrothermal silicon molybdenum rod 4 is threaded into the threaded hole 32 of the connecting block 31. The high-temperature resistant metal shell 33 and the inlay groove 34 enhance the connection stability. Simultaneously, the high-temperature resistant metal shell 33 can adapt to high-temperature environments and protect the connection parts. After connection, an external power supply is connected, and the electrothermal silicon molybdenum rod 4 begins to heat up and operate.Providing heat to related equipment, when the electric heating silicon molybdenum rod 4 undergoes dimensional changes due to thermal expansion and contraction during heating, the connecting component 3 can effectively buffer thermal stress through its own elastic deformation (high-temperature resistant metal shell 33 and connecting block 31), avoiding problems such as loosening and breakage at the connection points due to stress concentration, and significantly extending the service life of the silicon molybdenum rod and the connecting structure.
[0028] The working principle of the electrothermal silicon molybdenum rod with a base plate provided by this invention is as follows: First, the base plate 1 is welded to the working position. When it is necessary to adjust the height of the electrothermal silicon molybdenum rod 4, the mounting base 16 can be pushed because the sliding plate 15 is slidably connected to the slide rail 12, so that the sliding plate 15 slides in the slide rail 12. After reaching the appropriate position, the pin 14 is inserted between the slot 13 of the sliding plate 15 and the slot 13 parallel to the slide rail 12 (there will be multiple sets of parallel slots 13, and workers can prepare multiple pins 14 to insert into them) to fix the position of the mounting base 16, so as to flexibly adjust the horizontal position of the electrothermal silicon molybdenum rod 4 according to the actual use requirements. Then, the rotating shaft 24 is rotated according to the use requirements. The rotation of the rotating shaft 24 drives the mounting rod 25 to rotate synchronously. At this time, the mounting rod 25 drives the electrothermal silicon molybdenum rod 4 to rotate through the connecting component 3. When the electrothermal silicon molybdenum rod 4 rotates to the appropriate position, the tightening screw 261 can be tightened to make it abut against the rotating shaft 24 to prevent the rotating shaft 24 from rotating accidentally and to ensure the electrothermal silicon molybdenum rod is in the correct position. Once the angle of rod 4 is stable, the rotating wheel 27 is rotated. The rotating wheel 27 drives the mounting plate 22 to rotate around the bearing 21. The vertical plate 23, rotating shaft 24, and mounting rod 25 on the mounting plate 22 rotate accordingly, thereby changing the angle of the electrothermal silicon molybdenum rod 4. After adjusting to a suitable angle, the limiting post 28 is inserted into the corresponding limiting hole 29 to limit the rotation of the rotating wheel 27. The above steps complete the adjustment of the angle of the electrothermal silicon molybdenum rod 4. When installing the electrothermal silicon molybdenum rod 4, the lower end of the electrothermal silicon molybdenum rod 4 is threaded into the threaded hole 32 of the connecting block 31. The high-temperature resistant metal shell 33 and the inlay groove 34 enhance the connection stability. At the same time, the high-temperature resistant metal shell 33 can adapt to the high-temperature environment and protect the connection parts. After the connection is completed, the external power supply is turned on, and the electrothermal silicon molybdenum rod 4 begins to heat up and provide heat to the relevant equipment. When the electrothermal silicon molybdenum rod 4 undergoes dimensional changes due to thermal expansion and contraction during the heating process, the connecting component 3 can effectively buffer thermal stress through its own elastic deformation (high-temperature resistant metal shell 33 and connecting block 31).
[0029] It is worth noting that the electrothermal silicon molybdenum rod 4 disclosed in the above embodiments is a conventional electrothermal silicon molybdenum rod.
[0030] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
