Description

Technical Field

[0001] This application relates to the field of coil transportation technology, and in particular to an air-cooled device for conveying coiled wire. Background Technology

[0002] On a hot-rolled high-speed wire rod production line, the wire rod is laid out and conveyed flat after the rolling process. To facilitate subsequent storage, transportation, and processing, this flat wire rod needs to be collected into uniform vertical coils. This process is usually completed by a coiling station, and the efficiency and stability of the coiling station directly affect the production rhythm and output of the entire production line. The coiling station is generally located at the end of the loose coil cooling line of the high-speed wire rod production line. The flat wire rod is fed into the coiling station by a conveying device, and then the core frame (or winding tube) inside the coiling station begins to rotate. The wire rod is stacked from the bottom to the top of the core frame and gradually wound into a vertical coil. After winding, a lifting device raises the core frame together with the coil, and then a transfer device (such as a coil trolley) unloads the coil from the core frame and transports it to the subsequent P&F transport line.

[0003] Before being fed into the coiling station, coiled wire must undergo heat dissipation treatment to ensure its temperature drops to the specified standard. However, the current natural air cooling method is ineffective and cannot meet the cooling requirements of the wire. Although existing equipment uses multiple centrifugal fans for air cooling, these devices have insufficient utilization of fan resources, resulting in high equipment costs. At the same time, while maintaining the good cooling performance of the existing layout, it is difficult to further optimize the fan structure. The linkage between fans under different heat dissipation schemes is poor, and it is impossible to further improve the cooling effect through mutual cooperation. Summary of the Invention

[0004] This device provides an air-cooling apparatus for conveying coiled wire, and the specific implementation method is as follows:

[0005] A wind-cooled device for conveying coiled wire includes:

[0006] Several air-cooling components are located at the bottom of the roller conveyor belt along its conveying direction. Each air-cooling component consists of a central air-cooling component and a side air-cooling component. The side air-cooling component consists of two parallel centrifugal fans.

[0007] The central air-cooled component includes a single axial fan, and the outlets of four centrifugal fans in a single air-cooled component are arranged around the outlet of the axial fan. The axial fan provides cooling air to the edge junction of the inner side of each centrifugal fan.

[0008] The centrifugal fan's outlet is connected to an expansion hood via a ventilation duct. Each expansion hood covers the bottom of the roller conveyor belt along the conveying direction, providing air cooling for the entire roller conveyor belt.

[0009] Preferably, it also includes a frame for inclined clamping of the roller conveyor belt, and the end of the roller conveyor belt connected to the collecting drum is located at a high position.

[0010] Based on the above technical solution, an axial flow fan was introduced in the middle, replacing the two redundant centrifugal fans originally configured. This innovative design adjustment not only significantly reduced the overall cost of equipment purchase and operation and maintenance, but also achieved a dual optimization of cost and benefit while maintaining or even improving cooling efficiency. The axial flow fan can effectively cover the weak airflow area located at the edge of the air-cooled components, which was originally handled by two centrifugal fans. This change not only ensures the uniformity and efficiency of airflow distribution, but also significantly reduces the local overheating problems that may be caused by insufficient or uneven airflow, thereby further improving the stability and reliability of the entire system.

[0011] Preferably, the expansion shroud is provided with a pair of counter-rotating opening and closing guide plates; the side of the expansion shroud is provided with an arc-shaped limiting groove for limiting the flipping angle of the opening and closing guide plates, and the flipping center of the two is connected to the drive unit through a gear structure.

[0012] Based on the above technical solutions, by setting an adjustable opening and closing guide plate, the airflow distribution pattern in the front and rear directions inside the expansion shroud can be flexibly adjusted to achieve precise control of the airflow path; the introduction of the opening and closing guide plate can dynamically adjust the airflow direction and intensity according to the temperature difference at different positions of the coiled wire, ensuring that the cooling airflow can accurately act on the high-temperature area and effectively avoid the occurrence of local overheating; the drive unit can be hand-cranked or motor-driven.

[0013] Preferably, the air outlet of the axial flow fan in the middle air-cooled component is connected to a converging assembly, which is connected to the expansion shrouds on both sides, and the connection point is provided with a sliding sealing plate that can be opened and closed according to the wind pressure.

[0014] Preferably, the confluence assembly includes a confluence cavity with an opening at the top facing the roller conveyor belt, and a second air inlet and a first air inlet respectively at the side and bottom of the confluence cavity, which connect the expansion shroud and the air outlet of the axial flow fan.

[0015] Preferably, a limiting guide groove is provided at the second air inlet position, the end of the sliding seal plate is slidably disposed in the limiting guide groove, and its end face extends out of the limiting guide groove and is provided with a sliding block, the sliding block being connected to a spring reset structure.

[0016] Based on the above technical solution, a sliding sealing plate equipped with a spring return mechanism is installed. By controlling the direction of the opening and closing guide plate, the force applied by the centrifugal fan to the sliding sealing plate can be flexibly adjusted. This allows us to precisely control the force to open or close the sliding sealing plate according to actual needs, thus determining whether the axial flow fan and centrifugal fan air ducts intersect. This not only achieves intelligent management of the air-cooling system but also allows for free switching between independent and linked air-cooling modes. In independent air-cooling mode, the sliding sealing plate remains tightly closed, ensuring that the axial flow fan and centrifugal fan work independently without interference, suitable for applications with relatively simple or specific cooling requirements. When switching to linked air-cooling mode, by appropriately adjusting the direction and force of the opening and closing guide plate, the sliding sealing plate can be opened smoothly, allowing the air ducts of the axial flow fan and centrifugal fan to intersect and work together to cool the coiled wire, significantly enhancing cooling efficiency and flexibility.

[0017] Preferably, it further includes a detection box covered on the sliding block, and a spring is provided between the sliding block and the inner wall of the detection box; a spherical detection head is inserted laterally into the detection box, and the sliding block is provided with an arc hole for the spherical detection head to be inserted into, and the arc hole is connected to the second air inlet through a vertical through hole on the sliding block.

[0018] Based on the above technical solution, the monitoring of the wind force inside the second air inlet is realized by configuring the detection box and the spherical detection head; the spherical detection head can be seamlessly connected to the arc hole, thus perfectly constructing the detection flow channel.

[0019] Preferably, a magnetic attraction structure is provided between the sliding block and the inner wall of the detection box; a magnetic attraction block is provided on the side of the arc hole on the end face of the sliding block, and an electromagnet is provided on the side of the spherical detection head on the inner wall of the detection box.

[0020] Preferably, the end face of the sliding block is provided with an open groove for accommodating the spherical detection head rod.

[0021] Based on the above technical solutions, by setting up a combination of magnetic blocks and electromagnets, the position locking function of the opening and closing guide plate after the sliding seal is opened is realized. The magnetic principle ensures that the sliding seal can be stably maintained in the required position during the operation of the centrifugal fan, effectively preventing the reciprocating motion of the sliding seal caused by wind fluctuations, thereby greatly improving the stability and reliability of the air-cooling system; the magnetic blocks and the spherical detection head are coaxially installed, realizing the rational placement of the two.

[0022] Preferably, it also includes a filter screen disposed in the manifold cavity, the filter screen being inserted into the manifold cavity through a side-opening slot.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] 1. In this utility model, the middle two of the three fans in the traditional arrangement are combined into one axial fan, that is, one 185kw axial fan is used to replace two 160kw centrifugal fans, which reduces the procurement cost and maintains the good cooling performance of the original arrangement.

[0025] 2. This utility model is equipped with a sliding sealing plate with a spring reset function. By controlling the direction of the opening and closing guide plate, the magnitude of the force exerted by the centrifugal fan on the sliding sealing plate can be adjusted. According to the control of the force, the sliding sealing plate can be opened, thereby completing whether the axial flow fan and the centrifugal fan duct intersect, and realizing the switching between independent air cooling and linkage air cooling.

[0026] 3. This utility model has a simple structure. By setting up a magnetic block and an electromagnet, the magnetic attraction is used to realize the position locking of the sliding seal plate after it is opened, thus preventing the sliding seal plate from reciprocating due to wind fluctuations during the operation of the centrifugal fan.

[0041] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0042] This application discloses an air-cooling device for conveying coiled wire.

[0043] Example 1

[0044] Reference Figures 1 to 4 This embodiment discloses an air-cooling device for conveying coiled wire, including a frame 4 and several air-cooling components disposed at the bottom of the roller conveyor belt 1 along the conveying direction. Each air-cooling component consists of a central air-cooling component 3 and a side air-cooling component 2. The side air-cooling component 2 consists of two centrifugal fans 201 arranged in parallel. In this structure, the central air-cooling component 3 includes a single axial flow fan. The air outlets of four centrifugal fans 201 in a single air-cooling component are arranged around the air outlet of the axial flow fan. The axial flow fan provides cooling air for the wire to the edge intersection of the inner side of each centrifugal fan 201.

[0045] The outlet of the centrifugal fan 201 is connected to an expansion cover 203 through the ventilation duct 202. Each expansion cover 203 covers the bottom of the roller conveyor belt 1 in sequence along the conveying direction of the roller conveyor belt 1, providing air cooling effect for the entire roller conveyor belt 1. The frame 4 is used to clamp the roller conveyor belt 1 at an angle, and the end of the roller conveyor belt 1 connected to the collecting drum 6 is set at a high position.

[0046] Example 2

[0047] Reference Figures 1 to 6 Based on the above embodiments, this embodiment also discloses an air-cooling device for conveying coiled wire. The expansion cover 203 is provided with a pair of counter-rotating opening and closing guide plates 204. The side of the expansion cover 203 is provided with an arc-shaped limiting groove 205 for limiting the flipping angle of the opening and closing guide plates 204. The flipping center of the two is connected to the drive unit 5 through a gear structure. The air outlet of the axial flow fan in the middle air-cooling component 3 is connected to a converging component 7. The converging component 7 is connected to the expansion covers 203 on both sides, and a sliding sealing plate 8 is provided at the connection point, which can be opened and closed according to the wind pressure. In this structure, the wind pressure of the centrifugal fan 201 on the sliding sealing plate 8 is adjusted by opening and closing the guide plates 204, thereby realizing the combined cooling effect of the centrifugal fan 201 and the axial flow fan when the wind force is large, and the sliding sealing plate 8 closes when the wind force is small, realizing the independent cooling operation of the centrifugal fan 201 and the axial flow fan.

[0048] The confluence assembly 7 includes a confluence cavity 701 with an opening at the top facing the roller conveyor belt 1. The side and bottom of the confluence cavity 701 are respectively provided with a second air inlet 702 and a first air inlet 703 that connect the expansion cover 203 and the air outlet of the axial flow fan. A limiting guide groove 705 is provided at the position of the second air inlet 702. The end of the sliding sealing plate 8 is slidably disposed in the limiting guide groove 705, and its end face extends out of the limiting guide groove 705 and is provided with a sliding block 14. The sliding block 14 is connected to a spring reset structure.

[0049] A filter screen 10 is provided inside the manifold 701. The filter screen 10 is inserted into the manifold 701 through a side-opening slot 704. In this structure, the filter screen 10 can be quickly pulled out and cleaned through the open slot 704.

[0050] Example 3

[0051] Reference Figures 5 to 8Based on the above embodiments, this embodiment also discloses an air-cooling device for conveying coiled wire, which further includes a detection box 9 covered on a sliding block 14. A spring 13 is provided between the sliding block 14 and the inner wall of the detection box 9. A spherical detection head 11 is inserted laterally into the detection box 9. The sliding block 14 is provided with an arc hole 1401 for the spherical detection head 11 to be inserted into. The arc hole 1401 is connected to the second air inlet 702 through a vertical through hole 1402 on the sliding block 14. An open groove 1403 for placing the rod of the spherical detection head 11 is provided on the end face of the sliding block 14.

[0052] A magnetic attraction structure is provided between the sliding block 14 and the inner wall of the detection box 9. A magnetic attraction block 15 is provided on the side of the arc hole 1401 on the end face of the sliding block 14, and an electromagnet 12 is provided on the side of the spherical detection head 11 on the inner wall of the detection box 9. In this structure, the magnetic attraction locking between the sliding block 14 and the inner wall of the detection box 9 is realized when the spherical detection head 11 is in the detection state, which improves the stability and accuracy of the detection by the spherical detection head 11. The spherical detection head 11 can integrate a pressure detector and an air quality detector, and can provide feedback on the subsequent wind force adjustment of the centrifugal fan 201 according to the air inlet pressure.

[0053] The specific implementation process is as follows: When the opening and closing guide plates 204 on both sides are open and there is a gap between them, the cold air generated by the centrifugal fan 201 is dispersed outward through the expansion shroud 203; at this time, the impact force of the centrifugal fan 201 on the sliding sealing plate 8 is less than the elastic force of the spring 13, so the axial flow fan and the centrifugal fan 201 operate independently.

[0054] When the opening and closing guide plates 204 on both sides are closed, the airflow of the cold air generated by the centrifugal fan 201 through the sliding seal plate 8 increases, and its impact force is greater than the elastic force of the spring 13. Therefore, the sliding seal plate 8 opens, and the cold air from the centrifugal fan 201 interacts with the cold air from the axial fan to form a more effective air-cooled point. The intermittent strong air-cooled point improves the heat dissipation effect on the coiled wire. During this period, the electromagnet 12 is energized, and after it is attracted to the magnetic block 15, it achieves magnetic locking of the sliding seal plate 8, and the second air inlet 702 is in the normally open state.

[0055] Many other changes and modifications can be made without departing from the concept and scope of this utility model. It should be understood that this utility model is not limited to the specific embodiments, and the scope of this utility model is defined by the appended claims.
