Description

Technical Field

[0001] The utility model relates to the technical field of strip steel processing, in particular to a water-saving spray pipe device. Background Art

[0002] In tinplate production, strip width exhibits certain characteristics. The average width is approximately 900mm. However, during production line design, a maximum strip width of 1100mm is typically designed based on various factors. However, actual market demand shows that the majority of demand is concentrated in strip widths under 950mm, with strip widths exceeding 950mm accounting for only approximately 15% of overall demand.

[0003] During the spray-washing operation for steel strips, conventional spray pipe systems suffer from design flaws. They cannot flexibly adjust the spraying area and pattern based on the actual width of the strip. Consequently, when dealing with strips of varying widths, especially those less than 950mm, conventional spray pipe systems continue to spray the entire designed maximum width, resulting in significant water waste. This waste not only increases production costs but also goes against current principles of energy conservation, emission reduction, and sustainable development. Utility Model Content

[0037] Reference Figures 1 to 5, which is the first embodiment of the present utility model, proposes a water-saving spray pipe device for spray cleaning of strip steel, including a spray device 1, the spray device 1 includes a first spray pipe 2, the first spray pipe 2 has a first cavity 201 inside, one end of the first spray pipe 2 has a first water inlet 202, the first spray pipe 2 also has a plurality of first spray ports 203, and a first spray space is formed below the plurality of first spray ports 203; the number of the water outlet pipes 3 is several, and the plurality of the water outlet pipes 3 are all arranged on the first spray pipe 2 , one end of several of the water outlet pipes 3 is connected to several of the first spray ports 203; the second spray pipe 4 is sleeved on the outside of the first spray pipe 2, and a second cavity 401 is formed between the second spray pipe 4 and the first spray pipe 2. The other end of the water outlet pipe 3 extends out of the second cavity 401, and one end of the second spray pipe 4 has a second water inlet 402. The second spray pipe 4 also has several second spray ports 403. A second spray space is formed below the several second spray ports 403, and the second spray space is located on both sides of the first spray space.

[0038] In this embodiment, a water-saving spray pipe device is designed to address the problem of water waste caused by the inability to adjust the spray range of spray devices in related arts. The first spray pipe 2 is made of high-strength, corrosion-resistant material and has a first cavity 201 within it. One end of the first spray pipe 2 is connected to a first water inlet 202 for introducing cleaning water. Several first spray ports 203 are evenly distributed throughout the first spray pipe 2, forming a first spray space below these ports for preliminary spray cleaning of narrow-gauge steel strips. The number of outlet pipes 3 corresponds to the number of first spray ports 203. Each outlet pipe 3 is securely mounted on the first spray pipe 2, with one end connected to the first spray port 203. A second spray pipe 4 is sleeved onto the outside of the first spray pipe 2, forming a second cavity 401 between the two. The other ends of the outlet pipes extend out of the second spray pipe 4. A second water inlet 402 is provided at one end of the second spray pipe 4 for introducing a second line of cleaning water. A number of second spray ports 403 are also distributed on the second spray pipe 4. A second spray space is formed below these spray ports and is located on both sides of the first spray space, which can perform comprehensive spray cleaning on wide-spaced strip steel.

[0039] The advantage is that the spray pipe device, by providing the first spray pipe 2 and the second spray pipe 4, can achieve spray cleaning of both narrow and wide strip steel, thereby improving the cleaning effect. At the same time, the water flow can be controlled separately in different spray spaces as needed, thereby achieving the purpose of water conservation.

[0040] Furthermore, it also includes a frame 5; there are two fixing devices 6, and the fixing devices 6 are arranged in the frame 5. Both ends of the spraying device 1 are arranged in the frame 5 through the two fixing devices 6.

[0041] In this embodiment, a sturdy frame 5 is provided, welded from high-quality steel, capable of withstanding the weight of the spray device 1 and the impact forces during operation. Two fixing devices 6 are provided, one each disposed within the frame 5. These two fixing devices 6 securely attach the spray device 1 to the frame 5 at both ends, ensuring that the spray device 1 does not wobble or shift during operation.

[0042] The advantage is that the arrangement of the frame 5 and the fixing device 6 provides a stable installation base for the spray device 1, ensures the stability and reliability of the spray pipe device during operation, and improves the cleaning effect.

[0043] Furthermore, the fixing device 6 includes a mounting frame 601, which is arranged in the frame 5; there are two rotating arms 602, and both rotating arms 602 are rotatably arranged on the mounting frame 601, and an installation space is formed between the two rotating arms 602, and the installation space is used to fix one end of the spraying device 1.

[0044] In this embodiment, a mounting bracket 601 is disposed within the frame 5. Mounting bracket 601 is made of a sturdy metal material and is secured to the frame 5 via bolts and other fasteners. Two pivoting arms 602 are pivotally mounted on mounting bracket 601 via a rotating shaft. A mounting space is formed between the two pivoting arms 602, the size of which can be adjusted by rotating the pivoting arms 602. One end of the spray device 1 is placed within this mounting space and secured by the clamping action of the pivoting arms 602.

[0045] The advantage is that the setting of the rotating arm 602 makes the installation and removal of the spray device 1 more convenient and quick, thereby improving the maintenance efficiency of the equipment. At the same time, the rotating arm 602 can be adjusted according to the size of the spray device 1, thereby improving the versatility of the fixing device 6.

[0046] Furthermore, the fixing device 6 also includes a sliding block 603, which is slidably arranged in the mounting frame 601. The sliding block 603 has two first abutting surfaces 6031, and one end of the two rotating arms 602 abuts against the two first abutting surfaces 6031 respectively. After the sliding block 603 slides close to the frame 5, the other ends of the two rotating arms 602 approach each other, and the installation space is reduced.

[0047] In this embodiment, a sliding block 603 is disposed within the mounting frame 601. The sliding block 603 is made of a wear-resistant material and is capable of sliding smoothly vertically within the mounting frame 601. The sliding block 603 has two first abutment surfaces 6031, with one end of each of the two pivoting arms 602 abutting against each of these first abutment surfaces 6031. When the sliding block 603 slides toward the frame 5, it pushes one end of the two pivoting arms 602 away from each other, thereby bringing the other ends of the two pivoting arms 602 closer together, reducing the installation space and tightening the spray device 1.

[0048] The advantage is that the setting of the sliding block 603 makes the clamping of the rotating arm 602 more stable and reliable, which can effectively prevent the spray device 1 from loosening or falling off during operation. At the same time, the size of the installation space can be easily adjusted by sliding the sliding block 603 to accommodate spray devices 1 of different sizes.

[0049] Furthermore, the sliding block 603 also has a second abutting surface 6032 . After the spraying device 1 enters the installation space, it abuts against the second abutting surface 6032 , pushing the sliding block 603 close to the rack 5 .

[0050] In this embodiment, when the spray device 1 needs to be installed on the fixing device 6, the operator inserts one end of the spray device 1 into the installation space between the two rotating arms 602. At this time, the spray device 1 first contacts the second abutting surface 6032 of the sliding block 603. As the spray device 1 continues to move into the installation space, its contact with the curved surface generates a squeezing force on the sliding block 603.

[0051] Because the sliding block 603 is slidably mounted within the mounting frame 601, the compressive force of the spray device 1 causes the sliding block 603 to slide along the mounting frame 601 toward the frame 5. As the sliding block 603 slides, its two first abutting surfaces 6031 respectively contact one end of the two pivoting arms 602, pushing the pivoting arms 602 to rotate. As the two pivoting arms 602 rotate, their other ends approach each other, gradually shrinking the installation space. This ensures that the spray device 1 is securely fixed between the two pivoting arms 602, preventing it from loosening or shifting during the spraying process.

[0052] Furthermore, the frame 5 has a fixing hole 501 and also includes a fixing pin 7. The fixing pin 7 is slidably disposed in the fixing hole 501 to fix the relative position of the sliding block 603 and the frame 5.

[0053] In this embodiment, a fixing hole 501 is provided on the frame 5, and a fixing pin 7 is slidably disposed within the fixing hole 501. After the sliding block 603 slides to a suitable position to clamp the spray device 1, the fixing pin 7 is inserted into the fixing hole 501 to fix the relative position of the sliding block 603 and the frame 5, preventing the sliding block 603 from moving during operation.

[0054] The advantage is that the setting of the fixing pin 7 ensures the stability of the sliding block 603 during operation and ensures the clamping effect of the spray device 1. At the same time, the operation of the fixing pin 7 is simple and convenient, which improves the efficiency of the equipment.

[0055] Furthermore, the mounting bracket 601 is slidably arranged on the frame 5 , and the number of the fixing holes 501 is several.

[0056] In this embodiment, the mounting bracket 601 is slidably mounted on the frame 5, and the position of the mounting bracket 601 on the frame 5 can be adjusted as needed. The frame 5 is provided with a plurality of fixing holes 501, and the fixing holes 501 at different positions can realize multi-position fixing of the mounting bracket 601, thereby adapting to different installation requirements of the spray device 1.

[0057] The advantage is that the sliding setting of the mounting frame 601 and the design of multiple fixing holes 501 allow the position of the fixing device 6 to be flexibly adjusted, thereby improving the versatility and adaptability of the equipment and being able to meet the spraying needs in different production scenarios.

[0058] Furthermore, the second abutting surface 6032 is a curved surface.

[0059] In this embodiment, the second abutting surface 6032 is designed as an arc surface, and the curvature of the arc surface is optimized according to the shape and size of the spray device 1. The surface of the arc surface is smoothed to reduce friction with the spray device 1.

[0060] The advantage is that the curved second abutting surface 6032 can better fit the spray device 1, improving the clamping effect. At the same time, the smooth surface reduces the wear on the spray device 1 and extends the service life of the spray device 1.
