Description

Technical Field

[0001] This invention relates to the field of phosphorus removal equipment technology, and in particular to a phosphorus removal equipment and a method for assembling a phosphorus removal equipment. Background Technology

[0002] In slab casting machine marking equipment, the descaling unit is used to remove iron oxide scale (phosphorus scale) from the surface of the slab to ensure clear marking. In related technologies, the descaling unit adopts a split assembly method, meaning that the upper components (such as descaling plates and rods) must be installed first, and the base plate is installed last, secured with shaft-end thrust washers and fixing screws. However, this structure is prone to screw loosening under long-term impact and vibration, causing the descaling unit to disintegrate and components to be lost, seriously affecting production continuity and increasing economic losses. Summary of the Invention

[0012] In some embodiments, the dephosphorizer further includes a bearing and a bushing mounted on the main shaft, the bearing being located on the side of the baffle away from the upper chassis, and the bushing being located between the bearing and the baffle.

[0013] In some embodiments, the bushing is integrally formed with the baffle.

[0019] The first mounting hole of the upper chassis is inserted into the main shaft in a top-to-bottom direction;

[0020] The phosphorus removal component is installed between the upper chassis and the lower chassis.

[0021] The assembly method for the dephosphorizer provided in the second aspect has the same beneficial effects as the dephosphorizer provided in the first aspect, and will not be repeated here.

[0022] Thirdly, embodiments of this application provide a method for assembling a dephosphorizer, the assembly method being used to assemble the dephosphorizer described above, the assembly method comprising:

[0040] In the slab casting machine marking equipment, the descaling unit 10' is used to remove iron oxide scale (phosphorus scale) from the slab surface to ensure clear marking. Please refer to... Figure 1In related technologies, the descaling device 10' includes a main shaft 100', a shaft end thrust washer 200', a screw 210', an upper base 300', a lower base 400', and a descaling component 500'. The upper base 300' and the lower base 400' are arranged opposite to each other, and in the operating state of the descaling device 10', the upper base 300' is located above the lower base 400'. The main shaft 100' is inserted through the upper chassis 300' and the lower chassis 400'. The descaling component 500' is located between the upper chassis 300' and the lower chassis 400'. The shaft end thrust washer 200' is located on the bottom surface of the lower chassis 400'. The screw 210' connects the shaft end thrust washer 200' and the main shaft 100', thereby allowing the shaft end thrust washer 200' to axially limit the main shaft 100' and prevent the main shaft 100' from falling off the lower chassis 400'.

[0041] When assembling the descaling unit 10', the upper base 300' must first be installed on the main shaft 100', then the descaling component 500' is installed on the upper base 300', and then the lower base 400' is installed on the main shaft 100' and connected to the descaling component 500'. Finally, the main shaft 100' is locked in place using the shaft end thrust washer 200' and screws 210'. However, this structure is prone to loosening of the screws 210' under long-term impact and vibration, causing the descaling unit 10' to disintegrate and parts to be lost, seriously affecting production continuity and increasing economic losses.

[0042] To improve the above-mentioned technical problems to a certain extent, this application provides a descaling device and a descaling device assembly method, which can minimize the disassembly of the descaling device and the loss of parts, ensure production continuity, and reduce economic losses.

[0043] The embodiments of this application will now be described with reference to the accompanying drawings:

[0044] Please see Figures 2-5 This application provides a descaling device 10, which can be a descaling device in the form of a phosphorus plate. The descaling device 10 includes a main shaft 100, a limiting plate 200, an upper base 300, a lower base 400, and a descaling component 500. The limiting plate 200 is disposed at one end of the main shaft 100 and is integrally formed with the main shaft 100. The upper base 300 has a first mounting hole 310, and the lower base 400 has a second mounting hole 410. The main shaft 100 passes through the first mounting hole 310 and the second mounting hole 410. The limiting plate 200 abuts against the side of the lower base 400 away from the upper base 300. The descaling component 500 is installed between the upper base 300 and the lower base 400.

[0045] It should be noted that this article describes the position of the dephosphorizer 10 when it is in use. When the dephosphorizer 10 is in use, the upper base plate 300 and the lower base plate 400 are arranged opposite each other, with the upper base plate 300 located above the lower base plate 400 and the lower base plate 400 placed on the working surface.

[0046] The main shaft 100 passes through the first mounting hole 310 and the second mounting hole 410 to assemble the upper base plate 300 and the lower base plate 400 onto the main shaft 100. A limiting sleeve 110 can be provided on the main shaft 100, with both ends of the limiting sleeve 110 abutting against the upper base plate 300 and the lower base plate 400 respectively to prevent the upper base plate 300 from sliding downward. The main shaft 100 extends upward beyond the upper base plate 300. For ease of description, the portion of the main shaft 100 extending beyond the upper base plate 300 is named the extension portion 120. This extension portion 120 is used for transmission connection with the driving component. The driving component drives the main shaft 100 to rotate, thereby driving the upper base plate 300 and the lower base plate 400 to rotate, and further driving the descaling component 500 to rotate, so that the descaling component 500 can perform descaling operations. The working principle of the phosphorus plate type descaling device 10 is existing technology and will not be described in detail here.

[0047] The limiting plate 200 abuts against the side of the lower chassis 400 away from the upper chassis 300, that is, the limiting plate 200 abuts against the bottom surface of the lower chassis 400, and the limiting plate 200 covers the second mounting hole 410, thereby axially limiting the main shaft 100. Since the limiting plate 200 and the main shaft 100 are integrally set, the connection strength between the limiting plate 200 and the main shaft 100 is improved. Therefore, even under long-term impact and vibration, the limiting plate 200 and the main shaft 100 will not separate, thereby minimizing the possibility of disintegration of the descaling unit 10 and loss of parts, ensuring production continuity, and reducing economic losses.

[0048] Of course, as mentioned above, when assembling the descaling device 10 in the related technology, the upper chassis 300 is first installed on the main shaft 100, then the descaling component 500 is installed on the upper chassis 300, and then the lower chassis 400 is installed on the main shaft 100. However, in this embodiment, since the limiting plate 200 is integrally set with the main shaft 100, if the upper chassis 300 is installed first, then the lower chassis 400 cannot be installed on the main shaft 100 due to the obstruction of the limiting plate 200. Therefore, when assembling the descaling device 10 in this embodiment, the lower chassis 400 must be installed first, and then the upper chassis 300 and the descaling component 500 must be installed.

[0049] In some embodiments, the descaling component 500 includes a mounting rod 510 and a plurality of descaling sheets 520 stacked on the mounting rod 510. The upper base 300 has a first mounting hole 320, and the lower base 400 has a second mounting hole 420. One end of the mounting rod 510 is inserted into the first mounting hole 320, and the other end is inserted into the second mounting hole 420. The first mounting hole 320 penetrates the upper base 300.

[0050] The phosphorus removal plate 520 is used for phosphorus removal. One end of the mounting rod 510 is inserted into the first mounting hole 320, and the other end is inserted into the second mounting hole 420, so that the mounting rod 510 is assembled on the upper base 300 and the lower base 400. When the main shaft 100 drives the upper base 300 and the lower base 400 to rotate, the phosphorus removal component 500 also rotates accordingly, realizing phosphorus removal. The first mounting hole 320 penetrates through the upper base 300, that is, the first mounting hole 320 is a through hole, and the first mounting hole 320 penetrates through the upper and lower sides of the upper base 300.

[0051] Specifically, there can be multiple descaling components 500, which are spaced apart and arranged around the main shaft 100. Of course, there are also multiple first mounting holes 320 and second mounting holes 420.

[0052] In related technologies, the upper chassis 300 is first installed on the main shaft 100. Then, multiple mounting rods 510 are inserted into multiple first mounting holes 320, and descaling sheets 520 are installed on the mounting rods 510. Next, the lower chassis 400 is installed on the main shaft 100. The multiple second mounting holes 420 on the lower chassis 400 must correspond to the multiple first mounting holes 320, and the multiple mounting rods 510 must be absolutely perpendicular to ensure they can be inserted into their corresponding second mounting holes 420. However, when one end of a mounting rod 510 is inserted into a first mounting hole 320, the other end is free, which may cause deviations in the perpendicularity of the mounting rod 510. This necessitates repeated adjustments by the operator, resulting in low assembly efficiency.

[0053] In this embodiment, since the lower chassis 400 is first installed on the spindle 100 and the first mounting hole 320 passes through the upper chassis 300, after the lower chassis 400 is installed on the spindle 100, the upper chassis 300 can be installed on the spindle 100 first, and the multiple first mounting holes 320 on the upper chassis 300 are aligned with the multiple second mounting holes 420 on the lower chassis 400. Then, the descaling components 500 are stacked between each corresponding first mounting hole 320 and second mounting hole 420. Of course, the through hole of each descaling component 500 is aligned with the first mounting hole 320 and the second mounting hole 420. Finally, multiple mounting rods 510 are sequentially inserted into the corresponding first mounting hole 320 and the through holes of multiple descaling plates 520 in a top-to-bottom direction until they are inserted into the second mounting hole 420, thereby realizing the installation of the mounting rods 510. The multiple descaling plates 520 are also assembled on the mounting rods 510. In this way, by aligning the corresponding first mounting hole 320 and second mounting hole 420, it can be ensured that each mounting rod 510 can be smoothly inserted into the corresponding first mounting hole 320 and second mounting hole 420, thereby improving assembly convenience and assembly efficiency.

[0054] Specifically, the diameter of the first mounting hole 320 can be larger than the diameter of the mounting rod 510 to further facilitate alignment and installation. The diameter of the first mounting hole 320 can be 1mm-2mm larger than the diameter of the mounting rod 510.

[0055] In some embodiments, the dephosphorizer 10 further includes a baffle 600 and a fastener 610. The baffle 600 has a fixing hole through which the main shaft 100 passes. The baffle 600 is disposed on the side of the upper chassis 300 away from the lower chassis 400. The baffle 600 covers the first mounting hole 320. The fastener 610 connects the baffle 600 and the upper chassis 300.

[0056] Since the first mounting hole 320 penetrates both the upper and lower sides of the upper chassis 300, a baffle 600 and a fastener 610 are used to limit the mounting rod 510 from extending upwards through the first mounting hole 320. The baffle 600 has a fixing hole through which the spindle 100 passes, allowing the baffle 600 to be mounted on the spindle 100. The baffle 600 is located on the side of the upper chassis 300 away from the lower chassis 400, i.e., the baffle 600 contacts the top surface of the upper chassis 300. The baffle 600 covers the first mounting hole 320, and the fastener 610 connects the baffle 600 and the upper chassis 300, thereby limiting the mounting rod 510 and preventing it from extending upwards through the first mounting hole 320. Specifically, the fastener 610 can be a bolt.

[0057] In some embodiments, the dephosphorizer 10 also includes a bearing 700 and a bushing 620 mounted on the main shaft 100, the bearing 700 being located on the side of the baffle 600 away from the upper chassis 300, and the bushing 620 being located between the bearing 700 and the baffle 600.

[0058] The bearing 700 is located on the extension 120 of the main shaft 100. To prevent the bearing 700 from sliding downwards, in related technologies, a shoulder is machined on the main shaft 100 to limit the bearing 700. The shoulder is located between the bearing 700 and the upper base 300. Since the shaft end thrust washer is separate from the lower base 400 in related technologies, when assembling the descaling unit 10, the bearing 700 can be assembled onto the main shaft 100 first, and then the upper base 300, the descaling component 500, and the lower base 400 can be installed in sequence. The upper base 300, the descaling component 500, and the lower base 400 will not pass through the shoulder.

[0059] In this embodiment, since the lower chassis 400 and the limiting plate 200 are integrally set, when assembling the descaling device 10, the lower chassis 400 must first be installed on the main shaft 100. That is, the main shaft 100 passes through the second mounting hole 410 in the direction from bottom to top until the limiting plate 200 abuts against the bottom surface of the lower chassis 400. During this process, the entire main shaft 100 will pass through the second mounting hole 410, and subsequently the upper chassis 300 will also pass through the first mounting hole 310 in the direction from top to bottom. Finally, the bearing 700 is installed. Since the first mounting hole 310 and the second mounting hole 410 are matched with the main shaft 100, if a shoulder is provided on the main shaft 100, then neither the first mounting hole 310 nor the second mounting hole 410 can pass through the shoulder, so the upper chassis 300 and the lower chassis 400 cannot be assembled on the main shaft 100.

[0060] Therefore, in this embodiment, no shoulder is machined on the spindle 100, but a bushing 620 is provided to limit the bearing 700. That is, after the upper chassis 300, descaling component 500, lower chassis 400 and baffle 600 are all installed, the bushing 620 is assembled onto the spindle 100, and finally the bearing 700 is assembled onto the spindle 100.

[0061] Specifically, since the bushing 620 is located between the bearing 700 and the baffle 600, the bushing 620 and the baffle 600 can be installed as a single unit. That is, after the baffle 600 is installed, the bearing 700 can be installed, reducing the number of parts used and simplifying the assembly process of the dephosphorizer 10.

[0062] Please see Figure 4 In some embodiments, the lower chassis 400 is provided with a mounting groove 430, the second assembly hole 410 is provided at the bottom of the mounting groove 430, and the limiting plate 200 is provided in the mounting groove 430.

[0063] Since the lower chassis 400 needs to be placed on the working surface to support the overall structure, the limiting plate 200 is set in the mounting groove 430, which reduces the degree of protrusion of the limiting plate 200 from the lower chassis 400, thus preventing the lower chassis 400 from being unstable on the working surface and improving the operational stability of the dephosphorizer 10.

[0064] In some embodiments, the upper chassis 300, the lower chassis 400, and the descaling component 500 are made of 316Ti stainless steel.

[0065] In related technologies, the upper chassis 300, lower chassis 400, and descaling component 500 are made of 42CrMo material, which has insufficient high-temperature resistance and can only be used for one week. Frequent replacement increases costs and downtime. Furthermore, the upper chassis 300 and lower chassis 400 have low wear resistance; after prolonged operation, the first mounting hole 320 and the second mounting hole 420 will wear enlarge, resulting in unstable installation of the mounting rod 510. In this embodiment, because the upper chassis 300, lower chassis 400, and descaling component 500 are made of 316Ti stainless steel, high-temperature resistance and wear resistance are improved, comprehensively enhancing the reliability of the descaling device 10 and extending its service life.

[0066] Based on the same inventive concept, please refer to Figures 2-5 This application also provides a method for assembling a phosphorus remover 10, which is used to assemble the phosphorus remover 10 as described above. The assembly method includes:

[0067] S100: The spindle 100 is inserted into the second mounting hole 410, and the limiting plate 200 abuts against the bottom surface of the lower chassis 400.

[0068] S200: The first mounting hole 310 of the upper chassis 300 is inserted into the main shaft 100 in a downward direction.

[0069] S300: Install the descaling component 500 between the upper chassis 300 and the lower chassis 400.

[0070] The limiting plate 200 abuts against the side of the lower chassis 400 away from the upper chassis 300, that is, the limiting plate 200 abuts against the bottom surface of the lower chassis 400, and the limiting plate 200 covers the second mounting hole 410, thereby axially limiting the main shaft 100. Since the limiting plate 200 and the main shaft 100 are integrally set, the connection strength between the limiting plate 200 and the main shaft 100 is improved. Therefore, even under long-term impact and vibration, the limiting plate 200 and the main shaft 100 will not separate, thereby minimizing the possibility of disintegration of the descaling unit 10 and loss of parts, ensuring production continuity, and reducing economic losses.

[0071] In related technologies, the upper chassis 300 is first installed on the main shaft 100, followed by the descaling component 500 and the lower chassis 400. However, after the upper chassis 300 is installed, due to the gap between it and the working surface, the main shaft 100 cannot be directly supported on the working surface, meaning it cannot be fixed to the working surface, making it inconvenient to install the descaling component 500 and the lower chassis 400. Therefore, to facilitate the subsequent installation of the descaling component 500 and the lower chassis 400, the main shaft 100 needs to be inverted, and the extension portion 120 of the main shaft 100 needs to be clamped by a clamping device, so that the main shaft 100 can be fixed to the working surface, facilitating the installation of the descaling component 500 and the lower chassis 400. Finally, it is tightened with shaft end thrust washers and screws. After the entire assembly is completed, the descaling device 10 is inverted back. The whole process is quite cumbersome.

[0072] In this application, since the limiting plate 200 is integrally set with the main shaft 100, if the upper chassis 300 is installed first, the lower chassis 400 cannot be installed on the main shaft 100 due to the obstruction of the limiting plate 200. Therefore, when assembling the descaling device 10 in this embodiment, the lower chassis 400 must be installed first, followed by the upper chassis 300 and the descaling component 500. After the lower chassis 400 is installed, it can be stably placed on the working surface, serving to support the overall structure. This facilitates the subsequent installation of the upper chassis 300 and the descaling component 500 without having to turn the main shaft 100 upside down and clamp it with a clamping device, thereby improving the ease of assembling the descaling device 10.

[0073] Based on the same inventive concept, please refer to Figures 2-5 This application also provides a method for assembling a phosphorus remover 10, which is used to assemble the phosphorus remover 10 as described above. The assembly method includes:

[0074] S400: The spindle 100 is inserted through the second mounting hole 410, and the limiting plate 200 abuts against the bottom surface of the lower chassis 400.

[0075] S500: The first mounting hole 310 of the upper chassis 300 is inserted into the spindle 100.

[0076] S600: Align the through holes of the multiple dephosphorization plates 520 with the first assembly hole 310 and the second assembly hole 410 in sequence, and stack them on the lower chassis 400.

[0077] S700: Insert the mounting rod 510 sequentially through the second mounting hole 410 and the through holes of the multiple descaling plates 520 in a top-to-bottom direction until the mounting rod 510 is inserted into the first mounting hole 320.

[0078] In related technologies, the upper chassis 300 is first installed on the main shaft 100. Then, multiple mounting rods 510 are inserted into multiple first mounting holes 320, and descaling sheets 520 are installed on the mounting rods 510. Next, the lower chassis 400 is installed on the main shaft 100. The multiple second mounting holes 420 on the lower chassis 400 must correspond to the multiple first mounting holes 320, and the multiple mounting rods 510 must be absolutely perpendicular to ensure they can be inserted into their corresponding second mounting holes 420. However, when one end of a mounting rod 510 is inserted into a first mounting hole 320, the other end is free, which may cause deviations in the perpendicularity of the mounting rod 510. This necessitates repeated adjustments by the operator, resulting in low assembly efficiency.

[0079] In this embodiment, since the lower chassis 400 is first installed on the spindle 100 and the first mounting hole 320 passes through the upper chassis 300, after the lower chassis 400 is installed on the spindle 100, the upper chassis 300 can be installed on the spindle 100 first, and the multiple first mounting holes 320 on the upper chassis 300 are aligned with the multiple second mounting holes 420 on the lower chassis 400. Then, the descaling components 500 are stacked between each corresponding first mounting hole 320 and second mounting hole 420. Of course, the through hole of each descaling component 500 is aligned with the first mounting hole 320 and the second mounting hole 420. Finally, multiple mounting rods 510 are sequentially inserted into the corresponding first mounting hole 320 and the through holes of multiple descaling plates 520 in a top-to-bottom direction until they are inserted into the second mounting hole 420, thereby realizing the installation of the mounting rods 510. The multiple descaling plates 520 are also assembled on the mounting rods 510. In this way, by aligning the corresponding first mounting hole 320 and second mounting hole 420, it can be ensured that each mounting rod 510 can be smoothly inserted into the corresponding first mounting hole 320 and second mounting hole 420, thereby improving assembly convenience and assembly efficiency.
