Description

Technical Field

[0001] This application relates to the technical field of wire coil production, and particularly to a water bath and spray cooling system for high-speed wire coil production. Background Art

[0002] In modern industrial production, wire coils are widely used in many important fields such as power transmission, machinery manufacturing, construction engineering, and electronic equipment manufacturing. In the field of machinery manufacturing, the wire used to manufacture components such as springs and chains is also supplied in the form of wire coils. During the production process of wire coils, there is a crucial link that cannot be ignored - heat dissipation. When the wire is stretched and wound on a high-speed production line, a large amount of heat is generated due to the friction between the internal lattices of the metal and the friction with the die and equipment components. As production continues, if these heats cannot be dissipated in time, they will gradually accumulate inside the material. In some large-scale wire production factories, after continuous production for several hours, the temperature of the wire coil can rise by dozens of degrees Celsius, and the increase in temperature will affect the microscopic structure of the wire, thereby changing its physical properties such as hardness, toughness, and electrical conductivity.

[0003] In the traditional wire coil production process, heat dissipation has always been a thorny problem. The commonly used heat dissipation methods in the past, such as air cooling and natural cooling, generally have uneven heat dissipation. The cooling speeds of different parts of the wire are inconsistent, resulting in uneven internal stress distribution and affecting product quality. Moreover, the heat dissipation efficiency of these traditional methods is low. During high-speed wire coil production, heat accumulates rapidly, and the traditional heat dissipation methods simply cannot dissipate the heat in time, making it difficult to meet the current strict requirements for production efficiency and product quality. There is an urgent need for an efficient cooling method to change this situation. Some factories have tried to use spray cooling to quickly reduce the temperature of the wire. However, when the high-temperature wire comes into contact with the spray water, a large amount of water will splash out, which not only poses a serious threat to the safety of on-site operators and has a risk of scalding, but also pollutes the production environment. The disorderly discharge of the splashed water also causes waste of water resources. How to effectively recycle the splashed water has become a key technical problem that needs to be overcome by those skilled in the art. Summary of the Invention

[0004] This device provides a water bath and spray cooling system for high-speed wire coil production, and the specific implementation is as follows:

[0005] A water bath and spray cooling system for high-speed wire coil production, comprising:

[0006] A transport roller path for transporting wire coils, with both ends of the transport roller path connected to a wire laying head and a coil collecting station respectively;

[0007] A water cooling component and a blower arranged on the transport roller path;

[0008] The water-cooling assembly includes an upper spray member and a lower spray member disposed above and below the conveying roller path. The two share a liquid conveying assembly. The lower spray member is built into a water bath tank. The upper spray member and the lower spray member are provided with a plurality of nozzles facing the coil.

[0009] Water collecting tanks with upward openings are provided on both sides of the water bath tank. The water bath tank is divided into upper and lower parts by the lower spray member. A water baffle is installed at the top of the upper part where the liquid conveying assembly is not paved. The back of the water baffle is connected to the upper part of the water bath tank through a hollow plate.

[0010] A folding angle deflector is provided at the end of the hollow plate, and there is a return gap for splashed liquid between the folding angle deflector and the water collecting tank. The end of the return gap is connected to the lower part of the water bath tank.

[0011] Based on the above technical solutions, through the combined application of the water baffle, the hollow plate, the folding angle deflector and the water collecting tank, the recovery and secondary utilization of splashed water are realized, the impact of water on the environment is reduced, and water resources are saved at the same time. The water-cooling assembly has two working modes: First, it relies only on spraying for cooling. The spraying system is divided into two parts: upper spraying and lower spraying. When the coil is discharged from the coiler, the spraying system is immediately started. At this time, the circulating water at about 30 degrees Celsius is evenly sprayed onto the surface of the coil through the nozzles to achieve rapid cooling and temperature reduction of it. Except for part of the water lost due to evaporation, the remaining water will converge into the water bath tank and then be safely transported back to the external water treatment system for reuse by means of the liquid conveying assembly. Second, a more immersion cooling method is adopted. First, ensure that the valve of the liquid conveying assembly is in a closed state, and then inject water into the water bath tank through the spraying system until the water level is at least 100 millimeters higher than the roller surface of the conveying roller path, ensuring that all the rollers of the entire water bath roller path can be completely immersed in water. When the coil is discharged from the coiler, it will directly fall into the water for cooling. During the cooling process, the valve of the pipeline system will be adjusted to an appropriate opening to ensure that the spraying makeup water volume of the inlet pipeline is dynamically balanced with the evaporation volume and the water volume flowing out through the drainage pipeline, which can effectively prevent the cooling water from rising in temperature due to the cooling effect of the coil, thus maintaining the stability and high efficiency of the cooling effect.

[0012] Preferably, the lower spray member includes a plurality of communicating main pipes arranged longitudinally in parallel. A plurality of auxiliary pipes with nozzles installed are arranged between the main pipes, and the nozzles on the auxiliary pipes are overall dispersed in the middle and dense on both sides.

[0013] Preferably, a maintenance port is provided at the end of the main pipe of the lower spray member, and an openable maintenance plate is provided below the water bath tank.

[0014] Based on the above technical solutions, the lower spraying member is immersed in the water bath tank for a long time, and regular maintenance inside the lower spraying member can be achieved by setting a maintenance opening; the two sides of the nozzle are dense, which can ensure that the spray head can release more water flow in the two side areas, thereby increasing the heat dissipation rate of these areas. During the heat dissipation process, more water flow means higher heat exchange efficiency, which helps to quickly reduce the temperature of the surrounding environment; the water flow in the middle area is relatively dispersed, which can avoid excessive concentration of water flow leading to overcooling of local areas and also reduce waste of water resources.

[0015] Preferably, the liquid delivery assembly includes a water inlet pipeline and a drainage pipeline. The drainage pipeline is connected to the water collection tank and the water bath tank, and the water inlet pipeline passes through the water collection tank and is connected to the upper spraying member and the lower spraying member.

[0016] Preferably, the water inlet pipeline includes a main water inlet pipe, and the main water inlet pipe is respectively connected to the upper spraying member and the lower spraying member through a first branch pipe and a second branch pipe.

[0017] Preferably, the drainage pipeline is composed of a vertical branch pipe and a horizontal branch pipe that intersect. The intersection of the two is connected to the main drainage pipe. The vertical branch pipe is connected to the water collection tank, and the horizontal branch pipe communicates with the water bath tank.

[0018] Based on the above technical solutions, in the drainage pipeline, the vertical branch pipe, the horizontal branch pipe and the main drainage pipe form a tee structure at the intersection node; in addition, the other end of the horizontal branch pipe can be designed as a maintenance opening or reserved as a spare discharge port.

[0019] Preferably, it further includes a switching assembly and a locking assembly. The switching assembly is vertically slidably arranged in the vertical branch pipe, and the locking assembly is sleeved outside the vertical branch pipe. The end of the horizontal branch pipe is connected with a solenoid valve; an electromagnet that magnetically attracts the switching assembly is arranged above the inside of the vertical branch pipe. The on-off state of the drainage pipeline is changed by the weight of the accumulated water in the water collection tank. A linkage structure is arranged between the switching assembly and the locking assembly, and the locking assembly is triggered by the linkage structure to act inward on the switching assembly at the low position to lock the on-off state, so as to realize the secondary utilization of the accumulated water in the water collection tank.

[0020] Preferably, the switching assembly includes a cylinder and a sliding sleeve that are slidably arranged inside and outside the vertical branch pipe. The two are connected by a connecting rod, and the connecting rod passes through an axial through groove on the vertical branch pipe; a pressure sensor is arranged at the top of the cylinder, and a circumferential hollow plate is arranged at the end of the cylinder. When the hollow plate is in the low position, it communicates with the vertical branch pipe.

[0021] Preferably, the locking assembly includes a rotating ring rotatably arranged outside the vertical branch pipe. A plurality of hinged plates are arranged along the circumference on the inner side of the vertical branch pipe. The back of each hinged plate meshes with the inner side of the rotating ring. A positioning groove for the end of the hinged plate to be inserted is arranged at the bottom of the cylinder; an inclined panel is arranged at the top of the rotating ring, and a pressing joint is arranged at the bottom of the sliding sleeve. The pressing joint abuts against the inclined surface of the inclined panel.

[0022] Based on the above technical solutions, by equipping with a switching component and a locking component, the time-sharing interconnection function between the water bath tank and the water collection tank is realized; the switching component accurately regulates the connection state between the two according to the change in the weight of the stored water in the water collection tank; after the two are connected, the water bath tank is replenished with water through the liquid level difference, and the locking component further enhances the stability of the water body in the water collection tank during the secondary utilization process, ensuring the safe and efficient operation of the operation system.

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

[0024] 1. By comprehensively applying a water baffle, a hollow plate, a folded corner diversion plate, and a water collection tank, the present invention realizes the effective recovery and secondary utilization of splashed water, not only significantly reducing the potential impact of the water body on the surrounding environment, but also greatly promoting the conservation and recycling of water resources;

[0025] 2. In the present invention, through the synergistic effect of setting upper and lower double spraying and closed-loop water circulation in the spraying component, the cooling efficiency of the wire coil and the thermal energy utilization rate are significantly improved. The three-dimensional layout of the upper and lower spraying enables the cooling water to fully cover the surface of the wire coil, effectively eliminating the cooling blind area caused by traditional single-sided spraying;

[0026] 3. The structure of the present invention is simple. By adopting the immersion type dynamic balance cooling mechanism of the water bath tank, the control of thermal parameters during the wire coil cooling process is realized with the help of the water bath tank and the liquid delivery component. The liquid delivery component adjusts the opening degree of the pipeline valve in real time, so that the makeup water volume is kept in dynamic balance with the evaporation volume and the drainage volume, and the cooling water temperature rise is strictly controlled within the range of ±2°C, ensuring the uniformity of the phase change process of the wire coil;

[0027] 4. By setting a switching component and a locking component in the present invention, the switching component realizes the time-sharing interconnection between the water bath tank and the water collection tank, and the locking component strengthens the stability of the water body in the water collection tank during secondary utilization.

[0046] The following is combined with Figure 1-12 This application is further described in detail.

[0047] The embodiments of the present application disclose a water bath and spray cooling system for high-speed coil production.

[0048] Example 1

[0049] Reference Figures 1 to 8 , This embodiment discloses a water bath and spray cooling system for high-speed wire coil production, including a transport roller 1 for conveying wire coils, a water cooling component and a fan 10 arranged on the transport roller 1, and the two ends of the transport roller 1 are respectively connected to the spinning machine 13 and the coiling station 11. In this structure, the water cooling component includes an upper spray part 2 and a lower spray part 3 arranged on the upper and lower parts of the transport roller 1, and the two share a liquid conveying component 5. The lower spray part 3 is built into the water bath box 4, and the upper spray part 2 and the lower spray part 3 are provided with a plurality of nozzles 17 facing the wire coil. In this structure, the fan 10 is used for drying the wire coil after water cooling. The transport roller 1 is driven by a motor 15. The transport roller 1 is divided into a water bath roller 101, a drainage roller 102 and a lead-out roller 103 along its length. The draining roller 102 corresponds to the fan 10, and the lead-out roller 103 corresponds to the coiling station 11.

[0050] On both sides of the water bath tank 4, there are water collection tanks 6 with upward openings. The water bath tank 4 is divided into upper and lower parts by the lower spraying member 3. At the top of its upper part where the liquid conveying component 5 is not installed, a water baffle 401 is installed. The back of the water baffle 401 is connected to the upper part of the water bath tank 4 through a hollow plate 7. In this structure, the end of the hollow plate 7 is provided with a folded-angle diversion plate 12, and there is a return gap for the splashed liquid between the folded-angle diversion plate 12 and the water collection tank 6. The end of the return gap is connected to the lower part of the water bath tank 4. In this structure, an opening 402 communicating with the lower part of the water bath tank 4 is opened on the side of the water bath tank 4. The return gap is connected to the lower part of the water bath tank 4 through the opening 402. The overflow of the splashed water is reduced by the water baffle 401 and the water collection tank 6, and at the same time, the hollow plate 7 and the folded-angle diversion plate 12 collect the splashed water by reflux.

[0051] The liquid conveying component 5 includes a water inlet pipeline 501 and a drain pipeline 502. The drain pipeline 502 is connected to the water collection tank 6 and the water bath tank 4. The water inlet pipeline 501 passes through the water collection tank 6 and is connected to the upper spraying member 2 and the lower spraying member 3. The drain pipeline 502 is composed of a vertical branch pipe 5021 and a horizontal branch pipe 5022 that intersect. The intersection of the two is connected to a drain main pipe 5023. The vertical branch pipe 5021 is connected to the water collection tank 6, and the horizontal branch pipe 5022 communicates with the water bath tank 4.

[0052] The water inlet pipeline 501 includes a water inlet main pipe 5013, and the water inlet main pipe 5013 is respectively connected to the upper spraying member 2 and the lower spraying member 3 through a first branch pipe 5011 and a second branch pipe 5012.

[0053] The lower spraying member 3 includes a plurality of communicating main pipes arranged longitudinally in parallel. A plurality of auxiliary pipes with nozzles 17 installed are arranged between the main pipes. The nozzles 17 on the auxiliary pipes are overall dispersed in the middle and dense on both sides. In this structure, a maintenance port 18 is provided at the end of the main pipe of the lower spraying member 3, and an openable maintenance plate is provided below the water bath tank 4.

[0054] The specific implementation process is as follows: The water cooling component has two working modes. The first is to only use spraying. The spraying is divided into the upper spraying member 2 and the lower spraying member 3. When the wire coil is ejected from the wire spooling machine 13, the spraying system is in an open state. The single-loop water at about 30 degrees is sprayed out through the nozzles 17 and sprayed onto the surface of the wire coil to cool and lower the temperature of the wire coil. Except for the evaporated water, the remaining water converges into the water bath tank 4 and then returns to the external water treatment system through the liquid conveying component 5;

[0055] The second mode is that initially, the valve of the liquid delivery component 5 is in a closed state. Water is filled into the water bath tank 4 through spraying until the water level is higher than the roller surface of the transportation roller path 1 by 100 m, causing the rollers of the entire water bath roller path 101 to be immersed in water. When the wire coil is ejected from the wire spooling machine 13, it directly falls into the water for cooling. During the cooling process, the valve of the liquid delivery component 5 is opened to a certain extent to ensure that the spraying makeup water volume of the water inlet pipeline 501 is equal to the evaporation volume and the outflow volume through the drainage pipeline 502, so as to ensure that the cooling water temperature will not increase after cooling the wire coil.

[0056] Embodiment 2

[0057] Refer to Figures 8 to 12 , and based on the above embodiments, this embodiment also provides a water bath and spraying cooling system for high-speed wire coil production, which further includes a switching component 8 and a locking component 9. The switching component 8 is vertically slidably arranged on the vertical branch pipe 5021, and the locking component 9 is sleeved outside the vertical branch pipe 5021. The end of the horizontal branch pipe 5022 is connected with an electromagnetic valve 5024. In this structure, an electromagnet 16 with a magnetic attraction effect on the switching component 8 is arranged above the interior of the vertical branch pipe 5021. The conduction state of the drainage pipeline 502 is changed by the accumulated water weight in the water collection tank 6. A linkage structure is arranged between the switching component 8 and the locking component 9, and the locking component 9 is triggered by the linkage structure to act inwardly on the switching component 8 at the low position to lock this conduction state, realizing the secondary utilization of the accumulated water in the water collection tank 6.

[0058] The switching component 8 includes a cylinder 801 and a sliding sleeve 802 that are slidably arranged inside and outside the vertical branch pipe 5021. The two are connected by a connecting rod, and the connecting rod passes through the axial through groove 5025 on the vertical branch pipe 5021. In this structure, a pressure sensor 14 is arranged at the top end of the cylinder 801, and a circumferential hollow plate 804 is arranged at the end of the cylinder 801. When the hollow plate 804 is in the low position, it is communicated with the vertical branch pipe 5021, and the top end face of the hollow plate 804 is made of a magnetic attraction material;

[0059] The locking component 9 includes a rotating ring 902 rotatably arranged outside the vertical branch pipe 5021. A plurality of hinge plates 901 are arranged along the circumference inside the vertical branch pipe 5021. The back of each hinge plate 901 is engaged with the inside of the rotating ring 902. A positioning groove 805 for the end of the hinge plate 901 to be inserted into is arranged at the bottom of the cylinder 801. In this structure, a return spring is arranged between the rotating ring 902 and the vertical branch pipe 5021. An inclined panel 903 is arranged at the top of the rotating ring 902, and a pressure joint 803 is arranged at the bottom of the sliding sleeve 802. The pressure joint 803 abuts against the inclined surface of the inclined panel 903.

[0060] The specific implementation process is as follows: During the cooling operation, the cooling water splashes outside into the water collection tank 6. The column body 801 is in a high position due to the magnetic attraction effect between the end of the hollow plate 804 and the electromagnet 16. The impurity water in the water bath tank 4 is normally discharged from the drainage main pipe 5023 through the horizontal branch pipe 5022. As the water body accumulates in the water collection tank 6, when the weight of the water body is greater than the magnetic attraction of the electromagnet 16, the column body 801 falls to a low position. In this state, the water collection tank 6 is connected to the water bath tank 4 through the hollow plate 804 and the horizontal branch pipe 5022. The water bath tank 4 and the water collection tank 6 form a communicating vessel, and the water collection tank 6 replenishes water to the water bath tank 4. During this period, the column body 801 and the sliding sleeve 802 move downward synchronously. By using the pressure joint 803 to act on the inclined panel 903, the rotating ring 902 is forced to rotate, and then each articulated plate 901 engaged with it moves inward and is clamped into the positioning groove 805 to axially lock the column body 801.

[0061] When the liquid levels of the two are the same, the water pressure received by the pressure sensor 14 tends to be stable, and the magnetic force of the electromagnet 16 is strengthened, causing the column body 801 to reset. Then, the water bath tank 4 and the water collection tank 6 are no longer connected, and the water bath tank 4 drains water through the drainage main pipe 5023.

[0062] When the water quality of the water bath tank 4 and the water collection tank 6 deteriorates, the solenoid valve 5024 at the end of the horizontal branch pipe 5022 is regularly opened. The column body 801 is at the low position end, and the water bodies of both the water bath tank 4 and the water collection tank 6 are discharged outside through the horizontal branch pipe 5022 from the position of the solenoid valve 5024.

[0063] Many other changes and modifications can be made without departing from the concept and scope of the present invention. It should be understood that the present invention is not limited to a specific implementation manner, and the scope of the present invention is defined by the appended claims.
