Description

Technical Field

[0001] This utility model relates to the field of industrial slag removal technology, and in particular to a retractable ultrasonic vibration device for slag removal using submerged rollers. Background Technology

[0002] Submerged rollers are key components in continuous hot-dip galvanizing production lines, typically forming a "three-roller, six-arm" system together with stabilizing rollers and straightening rollers. The grooves machined on their surface promote the flow of molten zinc, helping the strip adhere to the roller surface and ensuring stable transport. Submerged rollers within the zinc pot are passive steering rollers, primarily driven by the friction between the strip and the roller surface, guiding the strip's direction within the zinc pot. Their surfaces are usually grooved to enhance friction through the flow of molten zinc, preventing slippage or deviation of the strip. Existing ultrasonic vibration cleaning equipment is only designed for water-based cleaning and lacks ultrasonic equipment for descaling the surface of submerged rollers within the zinc pot. Furthermore, the zinc pot contains molten zinc at a high temperature, making manual operation of related equipment for descaling the submerged rollers extremely inconvenient and dangerous. Utility Model Content

[0004] To achieve the above objectives, this utility model provides a retractable ultrasonic vibration device for slag removal from submerged rollers, comprising:

The rotating rod and the translational rod are threadedly engaged so that when the rotating rod rotates, the translational rod can translate. The translational rod is connected to the ultrasonic component to drive the ultrasonic component to move closer to or away from the submerged roller in the zinc pot.

[0008] In one embodiment, the fixing component includes a housing, a guide rod, and a connector. The connector is disposed on a crossbeam above the zinc pot. The two ends of the guide rod along its own axial direction are respectively connected to the housing and the connector. The driving component is disposed inside the housing. The first end of the rotating rod along its own axial direction is rotatably connected to the housing, and the second end of the rotating rod is rotatably connected to the connector. The guide rod and the translation rod are arranged intersectingly and pass through the translation rod.

[0009] In one embodiment, the driving component includes a drive motor and a gear set, the gear set being connected to the drive motor and the rotating rod respectively, so that the rotational speed of the rotating rod can be adjusted.

[0010] In one embodiment, the ultrasonic component includes a transducer, an amplitude transformer, and a radiation transformer connected in sequence.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] In related technologies, there is no dedicated ultrasonic equipment for use in the zinc pot and molten zinc in the key galvanizing process. This equipment needs to be applied to the zinc pot, using high-frequency vibration to remove slag from the surface of the submerged rollers. Furthermore, the length and structure of the amplitude transformer and radiation bar of the existing ultrasonic equipment are difficult to match well with actual industrial slag removal needs. To avoid introducing impurities, a suitable material for the ultrasonic radiation bar needs to be selected. The ultrasonic equipment is placed above the zinc pot, far from the platform, making manual handling inconvenient and dangerous.

[0025] In view of this, this application provides a retractable ultrasonic vibration device for deslag removal from submerged rollers, which is used to improve the above-mentioned technical problems.

[0026] Specifically, please refer to Figure 1 The ultrasonic vibration device includes an ultrasonic component 1, a fixed component, and a drive component 3.

[0027] The ultrasonic component 1 is configured to generate ultrasonic vibrations to remove slag from the surface of the submerged rollers inside the zinc pot. For example, when it is necessary to remove slag from the submerged rollers immersed in the molten zinc, the ultrasonic component 1 can approach the submerged rollers to perform ultrasonic slag removal, and when the slag removal is completed, the ultrasonic component 1 can also move away from the submerged rollers.

[0028] A fixing component connects to a crossbeam above the zinc pot. For example, the zinc pot is located within a production facility, which can be a steel structure building, and multiple crossbeams may be positioned vertically above the zinc pot. The fixing component is secured to the crossbeams to give the ultrasonic vibration equipment a relatively fixed position. The fixing component can be made of a material with sufficient strength and rigidity, such as metal.

[0029] Please see Figure 1 and Figure 2The drive assembly 3 includes a drive member 31 and a transmission member 32. The drive member 31 is disposed within the fixed assembly so that its position is also relatively fixed and located above the zinc pot. The transmission member 32 includes a rotating rod 321 and a translating rod 322. Both ends of the rotating rod 321 are rotatably connected to the fixed assembly along its own axial direction. The drive member 31 is configured to drive the rotating rod 321 to rotate, so that the rotating rod 321 can rotate relative to the fixed assembly under the drive of the drive member 31. The rotating rod 321 and the translating rod 322 are arranged intersectingly, for example, they can be arranged perpendicular to each other. The rotating rod 321 passes through the translating rod 322, and the rotating rod 321 and the translating rod 322 are threadedly engaged so that when the rotating rod 321 rotates, the translating rod 322 can translate. For example, the rotating rod 321 can be a lead screw, and the translating rod 322 has a threaded hole. The lead screw and the threaded hole of the translating rod 322 are threadedly engaged so that when the lead screw rotates, the translating rod 322 can translate along the axial direction of the lead screw. The translation rod 322 is connected to the ultrasonic component 1. For example, one end of the translation rod 322, axially away from the rotating rod 321, is connected to the ultrasonic component 1 to move the ultrasonic component 1 closer to or further away from the submerged roller in the zinc pot. For instance, the extension line of the movement path of the ultrasonic component 1 driven by the translation rod 322 intersects the submerged roller, so that when the ultrasonic component 1 approaches the submerged roller, the high-frequency vibration generated by the ultrasonic component 1 can remove slag from the surface of the submerged roller. After slag removal is completed, the ultrasonic component 1 stops working and moves away from the submerged roller. For instance, the material of the transmission component 32 can be a material with certain strength and rigidity, such as metal.

[0030] In this embodiment, the fixing component is suspended above the zinc pot, reducing the footprint of the ultrasonic vibration device and improving space utilization. The driving component 31 drives the rotating rod 321 to rotate. The rotating rod 321 is threadedly engaged with the translation rod 322, so that the rotation of the rotating rod 321 can be converted into the translation of the translation rod 322, thereby driving the movement of the ultrasonic component 1 connected to the translation rod 322. This allows the ultrasonic component 1 to be close to the submerged roller when slag removal is needed, and to be away from the submerged roller after slag removal. On the one hand, it eliminates the need for manual placement of the ultrasonic component 1 in the high-temperature zinc pot, or removal from the zinc pot, improving the safety and convenience of the submerged roller slag removal process. On the other hand, it also avoids the ultrasonic component 1 being immersed in the zinc pot for a long time, reducing the possibility of overheating and damage to the ultrasonic component 1.

[0031] In one embodiment, please refer to Figure 1The fixing assembly includes a housing 21, a guide rod 22, and a connector 23. The connector 23 is disposed on the crossbeam above the zinc pot. For example, the connector 23 is strip-shaped and is suspended from the crossbeam above the zinc pot. The two ends of the guide rod 22 along its own axial direction are connected to the housing 21 and the connector 23, respectively. The driving component 31 is disposed inside the housing 21. The first end of the rotating rod 321 along its own axial direction is rotatably connected to the housing 21, and the second end of the rotating rod 321 is rotatably connected to the connector 23. The guide rod 22 and the translation rod 322 are arranged crosswise and pass through the translation rod 322. For example, the guide rod 22 and the rotating rod 321 are arranged parallel to each other, so that when the rotating rod 321 rotates, the translation rod 322 can translate along the axial direction of the guide rod 22, thereby driving the ultrasonic component 1 to move closer to or away from the submerged roller along the axial direction of the guide rod 22, thereby enabling the ultrasonic component 1 to remove slag from the surface of the submerged roller more accurately.

[0032] In one embodiment, please refer to Figure 1 and Figure 2 The driving component 31 includes a drive motor 311 and a gear set 312. For example, the drive motor 311 can be a high-temperature resistant motor, or a heat insulation cover can be provided on the outer periphery of the drive motor 311 to enable the drive motor 311 to operate normally in high ambient temperatures. The gear set 312 is connected to the drive motor 311 and the rotating rod 321 respectively, so that the rotation speed of the rotating rod 321 can be adjusted. For example, the gear set 312 includes a first pinion, a first large gear, a second pinion, and a second large gear. The output shaft of the drive motor 311 is connected to the first pinion so that the first pinion can rotate. The first pinion meshes with the first large gear. When the first pinion rotates and drives the first large gear to rotate, the angular velocity of the first large gear is less than that of the first pinion. The first large gear and the second small gear are respectively connected to the two ends of the same rotating shaft. The second small gear has the same angular velocity as the first large gear. The second small gear meshes with the second large gear, making the angular velocity of the second large gear less than that of the second small gear. The second large gear is connected to the rotating rod 321, making the rotational speed of the rotating rod 321 less than the rotational speed of the output shaft of the drive motor 311. By adjusting the gear ratio of each gear in the gear set 312, the rotational speed of the rotating rod 321 can be adjusted, thereby also adjusting the movement speed of the ultrasonic component 1 towards or away from the submerged roller. This helps to reduce the possibility of the ultrasonic component 1 entering the zinc pot and causing the molten zinc to splash.

[0033] In one embodiment, please refer to Figure 1The ultrasonic component 1 includes a transducer 11, an amplitude transformer 12, and a radiation transformer 13 connected in sequence. The transducer 11 is configured to generate vibrations at a preset frequency. For example, the piezoelectric ceramic within the transducer 11 can generate high-frequency vibrations after electrical excitation. The amplitude transformer 12 is configured to amplify the vibrations generated by the transducer 11, and the radiation transformer 13 can transmit the vibrations of the amplitude transformer 12 to remove slag from the submerged roller located in the zinc pot. It should be noted that the amplification of the vibrations generated by the transducer 11 by the amplitude transformer 12 and the transmission of the vibrations by the radiation transformer 13 are mature existing technologies, and their mechanisms will not be elaborated here.

[0034] In one embodiment, the radiating rod 13 is made of Q235B to improve its corrosion resistance and also to help avoid introducing impurity elements into the molten zinc in the zinc pot. Furthermore, the Q235B material of the radiating rod 13 has a lower acoustic impedance, which helps ensure effective vibration output. It should be noted that the amplitude transformer 12 needs to be inserted into the molten zinc in the zinc pot; compared to other types of steel, Q235B has better corrosion resistance in molten zinc.

[0035] In one embodiment, the length of the radiating rod 13 is an integer multiple of half the wavelength when the radiating rod 13 vibrates, in order to obtain a better resonant length of the radiating rod 13. For example, the diameter of the radiating rod 13 can be 50 mm.

[0036] For example, the half-wavelength of the vibration of the radiating rod 13 can be calculated by the following formula:

[0037]

[0038] In the formula, Assuming the speed of sound, when the material of the radiating rod 13 is Q235B, the speed of sound in the radiating rod 13 is approximately 5932 m / s. Let be the vibration frequency, which can be 20kHz. Substituting this into the formula, we can obtain... It is 148mm.

[0039] The length of the radiating rod 13 can be six times half the wavelength, which is 890 mm. After finite element analysis, 906 mm is found to be the optimal resonant length of the radiating rod 13.

[0040] In one embodiment, please refer to Figure 1The amplitude transformer 12 includes a first amplitude transformer 121 and a second amplitude transformer 122 connected by flanges to improve the stability of the connection between the first amplitude transformer 121 and the second amplitude transformer 122. The end of the first amplitude transformer 121 facing away from the second amplitude transformer 122 along its own axial direction is connected to the transducer 11, and the end of the second amplitude transformer 122 facing away from the first amplitude transformer 121 along its own axial direction is connected to the radiating rod 13. The first amplitude transformer 121 amplifies the amplitude of the transducer 11, and the second amplitude transformer 122 amplifies the amplitude of the first amplitude transformer 121, so that the radiating rod 13 can have a larger amplitude. For example, a translation rod 322 can be connected at the flange connection between the first amplitude transformer 121 and the second amplitude transformer 122 to improve the stability of the connection between the translation rod 322 and the amplitude transformer 12.

[0041] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
