DETAILED DESCRIPTION

[0031] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0032] It should be noted that, unless otherwise defined, the technical or scientific terms used in the present invention should have the usual meanings understood by people with ordinary skills in the field to which the present invention belongs. The "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0033] In one embodiment, see Figures 1 to 4 The present invention provides a high-pressure water dephosphorization tank, comprising a dephosphorization tank body and at least one dephosphorization tube assembly disposed within the dephosphorization tank body. The dephosphorization tube assembly is arranged along the conveying direction of the plate, capable of spraying high-pressure water on the upper and lower end surfaces of the plate to remove the oxide layer on the plate surface.

[0034] The dephosphorization tube group includes a tube body 1 and at least one set of nozzle units 2. The tube body 1 is arranged along a horizontal plane and perpendicular to the plate conveying direction. The tube body 1 is connected to an external liquid supply device through a pipeline connection, and the liquid supply device is used to provide high-pressure dephosphorization water.

[0035] Each nozzle unit 2 includes:

[0036] The nozzle base 3 is threadedly fixed to the tube body 1 and has a connecting channel 301 inside. One end of the connecting channel 301 communicates with the inner cavity of the tube body 1, and the other end of the connecting channel 301 is fixed to the nozzle head 4. The high-pressure dephosphorization water flows through the tube body 1 into the connecting channel 301 and is then ejected through the nozzle head 4, forming a fan-shaped spray.

[0037] The connector 5 is slidably mounted in the nozzle base 3, and a sliding fit structure is formed between the connector 5 and the nozzle base 3. The connector 5 and the nozzle base 3 are slidably mounted to achieve quick disassembly and maintenance. When the nozzle or connector 5 needs to be replaced or repaired, there is no need to disassemble the entire pipe body 1 or the piping system. Only the corresponding parts need to be disassembled by sliding. This can significantly shorten the equipment maintenance time, reduce downtime losses, reduce the difficulty and cost of manual maintenance, and significantly improve the service life and operating economy of the dephosphorization box.

[0038] At least one material retaining bracket 6 is fixed to the connector 5 and arranged around the periphery of the nozzle head 4. The material retaining bracket 6 arranged around the periphery of the nozzle head 4 forms an effective obstruction area outside the nozzle head 4, preventing peeling materials such as oxide scale from falling directly onto the connector 5 or the nozzle base 3. Through physical barriers, the material retaining bracket 6 is prevented from causing collisions with the nozzle head 4 structure by hard particles such as oxide scale, thereby improving the service life of the nozzle head 4, extending the maintenance cycle of the dephosphorization box, reducing the cleaning frequency and labor intensity, and the sliding structure of the connector 5 has a certain buffering capacity, which can absorb the impact force generated during the high-pressure spraying process and the impact force when the oxide scale falls, effectively reducing the stress damage of the material retaining bracket 6 and the connector 5, and extending the service life of the material retaining bracket 6.

[0039] Specifically, this example adopts a modular structural design, which facilitates the overall disassembly and assembly of the nozzle unit 2, improves the maintenance efficiency of the phosphorus removal pipe group, and at the same time adds a connector 5 and a material blocking bracket 6 in the nozzle unit 2. Through physical barriers, it prevents hard particles such as oxide scale from colliding with the nozzle head 4 structure, thereby improving the service life of the nozzle head 4 and extending the maintenance cycle of the phosphorus removal box. In addition, the sliding structure of the connector 5 has a certain buffering capacity, which can absorb the impact force generated during high-pressure spraying and the impact force when the oxide scale falls, effectively reducing the stress damage of the material blocking bracket 6 and the connector 5, and extending the service life of the material blocking bracket 6.

[0040] In an alternative example, see Figures 1 to 5 As shown, an electromagnetic generator 7 is fixed inside the connector 5. The electromagnetic generator 7 has an electromagnetic end 71 that can generate magnetic force. The material blocking bracket 6 is made of magnetic conductive material. The electromagnetic end 71 contacts the connector 5 and can transmit the magnetic force to the material blocking bracket 6. The electromagnetic generator 7 is an electromagnet, which is connected to an external control device via a line connection. The control device can collect images of the oxide scale falling, control the magnetic strength, or trigger the operation.

[0041] Specifically, this example realizes the transmission of magnetic force through the cooperation of the electromagnetic generator 7, the connecting member 5 and the material blocking bracket 6, so that the material blocking bracket 6 has the ability to actively absorb the oxide scale to prevent the oxide scale from splashing onto the nozzle head 4. At the same time, the electromagnetic component is periodically powered on and off to achieve the effect of magnetic vibration, so that the oxide scale adsorbed on the material blocking bracket 6 automatically falls off, and the deposits on the material blocking bracket 6 can be automatically cleared during operation. In addition, the electromagnetic component can generate a certain suction force with the nozzle base 3, so that the sliding of the connecting member 5 produces a certain damping, thereby preventing the connecting member 5 from sliding too fast and frequently impacting the nozzle base 3.

[0042] In an alternative example, see Figures 1 to 5As shown, the nozzle base 3 has a sliding groove 302 arranged along the direction of the connecting channel 301, and a limiting flange 303 is provided at the end of the sliding groove 302 facing away from the tube body 1. The connecting member 5 is slidably inserted into the sliding groove 302. The diameter of the limiting flange 303 is smaller than the diameter of the sliding groove 302, forming a stepped limiting structure to prevent the connecting member 5 from sliding out of the sliding groove 302.

[0043] Specifically, this example achieves rapid installation of the connecting member 5 through the sliding cooperation between the sliding groove 302 and the connecting member 5, improves the disassembly efficiency of the nozzle unit 2, and the stepped limiting flange 303 structure can limit the position of the connecting member 5 to prevent the connecting member 5 from sliding out of the sliding groove 302.

[0044] In an alternative example, see Figures 1 to 6 As shown, the nozzle base 3 includes an upper body 31 and a lower body 32 fixed to each other by bolts. A sliding groove 302 is defined in the upper body 31 and extends along the connecting passage 301. The other end of the sliding groove 302 passes through the end of the upper body 31 near the lower body 32. A limiting flange 303 is provided at the end of the upper body 31 away from the lower body 32. A connecting pipe 1 321 for connecting to the pipe body 1 is provided at the end of the lower body 32 facing away from the upper body 31. A connecting pipe 2 322 for connecting to the nozzle head 4 is provided at the end of the lower body 32 facing toward the upper body 31. The connecting pipes 1 321 and 322 are interconnected and, together, form the connecting passage 301. The connecting member 5 is slidably inserted into the sliding groove 302. The connecting pipe 1 321 is connected to the pipe body 1 by a threaded connection. The connecting member 5 is an annular structure with an inner diameter larger than the connecting pipe 2 322.

[0045] Specifically, this example splits the nozzle base 3 into an upper base body 31 and a lower base body 32, which facilitates the processing and assembly of the nozzle base 3, reduces the manufacturing difficulty and assembly difficulty of the nozzle base 3, and the connecting channel 301 formed by the combination of connecting pipe 1 321 and connecting pipe 2 322 can ensure the sealing of the connecting channel 301 and ensure the pressure level of the dephosphorization water.

[0046] In an alternative example, see Figures 1 to 7As shown, the connector 5 has a mounting cavity 501, into which a retaining base 8 is inserted and fixed. The electromagnetic generator 7 is inserted and fixed in the mounting cavity 501, and contacts the retaining base 8 to form a controllable electromagnetic driving force. The retaining bracket 6 is fixed to the retaining base 8. The outer wall of the connector 5 has a plurality of guide grooves 502 connected to the mounting cavity 501. The retaining bracket 6 is inserted into the guide grooves 502 and can slide along the guide grooves 502 to prevent the connector 5 from interfering with the movement of the retaining bracket 6. The connector 5 has a guide groove 503 extending through the connector 5 along the direction of the connecting channel 301. The outer wall of the connector 5 is provided with a sliding flange 504. The inner wall of the sliding groove 302 has a sliding groove 3021 matching the sliding flange 504, which limits the sliding of the connector 5 and prevents the connector 5 from rotating during sliding. The connecting pipe 1 321 passes through the guide groove 503.

[0047] Specifically, the cooperation between the sliding flange 504 and the sliding groove 3021 in this example ensures that the sliding structure of the material blocking bracket 6 in the guide groove 502 ensures a stable motion trajectory, avoids the deviation of the material blocking bracket 6, and affects the spraying of high-pressure dephosphorization water. The material blocking bracket 6 is fixed by the material blocking base 8, which facilitates the disassembly, assembly and maintenance of the connecting part 5, thereby improving the maintenance efficiency of the nozzle unit 2.

[0048] In an alternative example, see Figures 1 to 8 As shown, the connector 5 includes a connecting portion 1 51 and a connecting portion 2 52 that are interconnected. The connecting portion 1 51 is provided with a bottom hole 1 511 that passes through the connecting portion 1 51. The end of the connecting portion 1 51 facing the connecting portion 2 52 is provided with a connecting groove 512. The inner wall of the connecting groove 512 is provided with an internal thread. The connecting portion 2 52 is fixed in the connecting groove 512 by a threaded connection. The end of the connecting portion 2 52 facing the connecting portion 1 51 is provided with a mounting groove 521. The bottom of the mounting groove 521 is provided with a bottom hole 2 522 that passes through the connecting portion 2 52. The end of the connecting portion 1 51 facing the connecting portion 2 52 is combined with the mounting groove 521 to form a mounting cavity 501. The bottom hole 1 511 and the bottom hole 2 522 are combined to form a guide groove 503. The guide groove 502 is provided on the outer wall of the connecting portion 2 52 and is connected to the mounting groove 521. The connecting portion 1 51 and the connecting portion 2 52 can be made of non-magnetic conductive materials, such as titanium alloy, high-temperature resistant plastic, etc.

[0049] Specifically, this example splits the connector 5 into two parts, a connecting part 1 51 and a connecting part 2 52 , which reduces the difficulty of manufacturing and disassembling the nozzle unit 2 , facilitates the maintenance of the nozzle unit 2 , and reduces the manufacturing cost of the nozzle unit 2 .

[0050] In an alternative example, see Figures 1 to 8As shown, a protruding guide ring 513 is provided at one end of the connecting portion 1 51 away from the connecting portion 2 52, and the connecting pipe 2 322 passes through the guide ring 513. A spring 9 is mounted on the outer wall of the connecting pipe 2 322, and one end of the spring 9 is in conflict with the connecting portion 1 51, and the other end of the spring 9 is in conflict with the end of the connecting pipe 2 322.

[0051] Specifically, in this example, the elastic force of the spring 9 pushes the connector 5 to move away from the nozzle base 3, so that the connector 5 has the ability to reset and buffer, reducing the direct impact on the nozzle base 3 and increasing the service life of the nozzle unit 2.

[0052] In an alternative example, see Figures 1 to 8 As shown, a conductive ring 10 is fixed in the nozzle base 3 by means of bolt connection, and two groups of conductive parts 11 are fixed in the connecting part 5. The conductive part 11 has a sliding part 111. The sliding part 111 slides against the conductive ring 10 and can be electrically connected. The conductive part 11 is electrically connected to the electromagnetic generating part 7.

[0053] Specifically, this example realizes power transmission through the cooperation of the conductive ring 10 and the conductive part 11, avoiding the risk of direct exposure of the line to oxide scale rupture, and the sliding part 111 of the conductive part 11 forms a sliding resistance contact with the conductive ring 10, and can still maintain a stable electrical connection in a mobile and dynamic working environment, thereby improving the reliability of electrical transmission and reducing the failure rate.

[0054] In an alternative example, see Figures 1 to 12 As shown, the conductive ring 10 includes an insulating ring 101 installed in the sliding groove 302 by bolt connection. The inner wall of the insulating ring 101 is fixed with a positive arc-shaped conductive sheet 102 and a negative arc-shaped conductive sheet 103. The conductive member 11 is inserted into the guide ring 513. One end of the conductive member 11 extends into the connecting groove 512. The other end of the conductive member 11 is a sliding portion 111. The two sets of sliding portions 111 respectively contact the positive arc-shaped conductive sheet 102 and the negative arc-shaped conductive sheet 103. Among them, the conductive member 11 is made of a conductive metal material wrapped with an insulating layer, such as a copper alloy; the positive arc-shaped conductive sheet 102 and the negative arc-shaped conductive sheet 103 are also made of a conductive metal material, such as a copper alloy; the positive arc-shaped conductive sheet 102 and the negative arc-shaped conductive sheet 103 are connected to an external power supply device via a line connection.

[0055] Specifically, this example achieves stable current transmission through the cooperation of the positive arc-shaped conductive sheet 102, the negative arc-shaped conductive sheet and the sliding portion 111, further ensuring the stability of the electrical connection.

[0056] In an alternative example, see Figures 1 to 12As shown, the material blocking base 8 includes a material blocking seat body 81, and the material blocking seat body 81 is made of magnetic conductive material, such as iron alloy, etc. The upper end of the material blocking seat body 81 is provided with a groove 1 811 and a groove 2 812, and the outer wall of the material blocking seat body 81 is provided with at least one group of positioning grooves 1 813 and positioning grooves 2 814, the positioning groove 1 813 is connected to the groove 1 811, and the positioning groove 2 814 is connected to the groove 2 812, and the material blocking bracket 6 is formed by bending a steel wire into a circular structure, which has a first end 61 and a second end 62, the first end 61 is inserted into the positioning groove 1 813, and It extends to groove one 811, the second end portion 62 is inserted into the positioning groove two 814, and extends to groove two 812. A positioning ring one 82 for fixing the first end portion 61 is fixed in the groove one 811 by means of bolt connection. The positioning ring one 82 conflicts with the first end portion 61 and fixes the first end portion 61 in the positioning groove one 813. A positioning ring two 83 for fixing the second end portion 62 is fixed in the groove two 812 by means of bolt connection. The positioning ring two 83 conflicts with the second end portion 62 and fixes the second end portion 62 in the positioning groove two 814.

[0057] Specifically, the structural design of the material blocking seat 81 in this example makes the installation path of the material blocking bracket 6 intuitive and clear, and facilitates quick positioning and assembly. The split structural design of the positioning groove and the groove, through the positioning ring and the bolt fastening cooperation, ensures that the two ends of the material blocking bracket 6 are accurately embedded and fixed, effectively avoiding the displacement or falling off of the bracket due to external force. At the same time, the material blocking bracket 6 with the steel wire bent into a ring-shaped structure saves materials and maintains structural toughness, taking into account both manufacturing costs and functions.

[0058] In general, the present invention adopts a modular structural design to add a connector 5 and a material blocking bracket 6 in the nozzle unit 2. The sliding structure and physical barrier of the connector 5 can prevent hard particles such as oxide scale from colliding with the nozzle head 4 structure, thereby improving the service life of the nozzle head 4 and extending the maintenance cycle of the dephosphorization box. The electromagnetic generator 7, the connector 5 and the material blocking bracket 6 cooperate to realize the transmission of magnetic force, so that the material blocking bracket 6 has the ability to actively adsorb oxide scale, avoid the oxide scale from splashing to the nozzle head 4, and has the function of automatically clearing deposits. At the same time, the conductive ring 10 and the conductive part 11 are added to realize power transmission, avoid the risk of the line being directly exposed to the oxide scale and rupture, and can still maintain a stable electrical connection in a mobile and dynamic working environment, thereby improving the reliability of electrical transmission and reducing the failure rate.
