Description

Technical Field

[0001] The utility model relates to the technical field of steel processing, in particular to a steel coil cooling pool. Background Art

[0002] Coil cooling pools are specialized equipment used to reduce the surface temperature of raw steel coils, typically installed during the transfer process of a steel production line. Excessive temperatures during the hot-rolled coil rolling process can severely impact the finishing mill, potentially damaging it. The cooling pool uses a spray system to apply clean water to the coil surface, rapidly cooling it and ensuring it reaches a safe temperature before entering the finishing mill. Therefore, coil cooling pools are an integral part of the steel production process. Effective cooling measures ensure smooth coil transfer and prevent damage to the finishing mill, playing a crucial role in maintaining production efficiency and product quality.

[0003] The existing steel cooling pool is shown in the Chinese patent application number: 202221498428.X: A steel cooling pool, which includes: a liquid storage mechanism, on which a lifting mechanism and a circulation mechanism are provided; the liquid storage mechanism includes a water reservoir, and the lower part of one side of the water reservoir is connected to a drain pipe, and a valve is installed on the drain pipe; the circulation mechanism includes a horizontal water pump installed on the upper part of one side of the water reservoir, and the water outlet end of the horizontal water pump is connected to an infusion pipe, and the end of the infusion pipe away from the horizontal water pump is sealed and penetrates into the inner cavity of the water reservoir, and the water inlet end of the horizontal water pump is connected to a connecting pipe, and the end of the connecting pipe away from the horizontal water pump is connected to a filter cartridge through a flange, and the bottom of the filter cartridge is connected to a heat dissipation water pipe.

[0004] The existing technology has the following defects: in the above-mentioned steel cooling pool, the steel to be cooled needs to be placed on a placement plate, and then the placement plate is placed in the coolant. When a large number of steels are cooled, the coolant gradually becomes ineffective and the cooling effect is reduced. When the coolant is replaced, the operation needs to be stopped for replacement, resulting in the cooling process of the steel being unable to proceed continuously. The cooling efficiency of the steel is low, which may affect the progress of subsequent processes of the steel and ultimately affect the overall production cycle and cost. Therefore, there is room for improvement. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the utility model provides a steel coil cooling pool to solve the technical problem that the coolant in the existing steel cooling pool needs to be stopped and replaced after a certain period of use, resulting in low cooling efficiency of the steel.

[0006] The utility model is achieved through the following technical solutions:

[0007] A steel coil cooling pool includes a pool body, a sliding assembly and a spray assembly. The sliding assembly includes a track and a sliding trolley. The track is arranged along the length direction of the pool body. The sliding trolley can slide along the track. The steel coil is placed on the sliding trolley. The spray assembly includes a spray pipe and a water pump. The spray pipe is connected to the water pump and is arranged at equal intervals along the length direction of the pool body.

[0008] Preferably, grooves are arranged at equal intervals on the track, and a switch assembly is arranged in the groove. The switch assembly includes a T-shaped rod and a spring. The two ends of the spring are respectively connected to the horizontal rod of the T-shaped rod and the inner bottom surface of the groove. When the horizontal rod of the T-shaped rod compresses the spring downward, the water passage of the sprinkler pipe is opened.

[0009] Preferably, a water collecting ditch is provided on the pool body, and the water collecting ditch is arranged along the length direction of the pool body, and the water collecting ditch is used to guide and recover the spray water.

[0010] Preferably, a sedimentation tank is further provided on one side of the tank body, and the water collecting ditch guides the spray water into the sedimentation tank.

[0011] Preferably, a clean water tank is further provided in the sedimentation tank, and the water pump pumps the clean water in the sedimentation tank into the clean water tank for storage.

[0012] Preferably, the upper cover of the water collecting ditch is provided with a filter plate, and the filter plate is used to filter impurities in the spray water, and the filter plate is arranged as a double layer.

[0013] Preferably, the upper end surface of the skid vehicle is set as a slope with high sides and low middle, and the steel coil is rolled and placed in the two sets of slopes.

[0014] Preferably, a mounting groove is concavely provided on the slope of the upper end surface of the skid vehicle, and a roller is rotatably mounted in the mounting groove.

[0015] The beneficial effects of the utility model are:

[0016] 1. By introducing the sliding assembly, the steel coil can enter the cooling pool immediately after external processing (such as rolling, heating, etc.), minimizing the time loss caused by waiting for cooling, achieving the continuity of the production process, and improving overall production efficiency; the spray assembly can evenly spray the coolant to ensure a more uniform temperature distribution of the steel coil during the cooling process, reducing the internal stress caused by temperature differences, thereby reducing quality problems such as deformation and cracks, ensuring high product consistency and extending service life;

[0017] 2. The switch assembly ensures that the spray pipe sprays water only when the steel coil passes through the spray zone, reducing the continuous waste of water flow in the spray pipe at other times and significantly reducing water consumption during the cooling process. The slope design allows the steel coil to roll on the skid trolley instead of sliding, which has less friction resistance than sliding friction, thereby reducing the power required for the skid trolley to move. The roller setting reduces the actual contact surface area, reducing the resistance of the steel coil when rolling, making the sliding process smoother and reducing the load on the motor.

[0018] 3. The suspended matter and sediment in the spray water are naturally settled by gravity in the sedimentation tank, thereby effectively removing solid impurities in the water and improving the quality of the recycled water. The setting of the clear water tank can effectively store the clear water after sedimentation treatment, which is convenient for subsequent use and management, and helps to improve the water resource utilization efficiency of the entire system. The double-layer filter plate design can evenly distribute the pressure of the water flow on two levels, thereby improving the overall filtration efficiency and extending the service life of the filter plate.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0031] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0032] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0033] See also Figures 1-6 A steel coil cooling pool includes a pool body 1, a sliding assembly 2 and a spray assembly 3. The sliding assembly 2 includes a track 21 and a sliding car 22. The track 21 is arranged along the length direction of the pool body 1. The sliding car 22 can slide along the track 21. The steel coil 4 is placed on the sliding car 22. The spray assembly 3 includes a spray pipe 31 and a water pump 32. The spray pipe 31 is connected to the water pump 32. The spray pipe 31 is arranged at equal intervals along the length direction of the pool body 1.

[0034] The working principle of the steel coil 4 cooling pool of this application is as follows:

[0035] The continuous cooling of steel is realized, and the cooling efficiency of steel is improved. The continuous cooling of steel is realized, and the cooling efficiency of steel is improved. The track 21 of the sliding car 22 is set along the length direction of the cooling pool, allowing the sliding car 22 to move freely at any position in the pool. Through electric drive or manual operation, the sliding car 22 can push the placed steel coil 4 into the spray area of ​​the cooling pool; when the steel coil 4 slides along the track 21, the spray assembly 3 starts to work, and the spray pipe 31 is connected to the water pump 32, which is responsible for The cooling liquid is transported to the spray pipe 31, and the spray pipe 31 sprays the cooling liquid evenly on the steel coil 4. The spray pipe 31 is arranged along the length of the pool body 1, which can realize the simultaneous cooling of multiple steel coils 4; the used cooling liquid circulates in the pool, and after cooling and filtering, it is again sent to the spray pipe 31 through the water pump 32 to ensure the continuity and uniformity of the cooling effect; as the sliding car 22 moves, the steel coil 4 is fully cooled in the spray area and can continue to move forward to the outlet area of ​​the cooling pool to complete the cooling process.

[0036] Due to the introduction of the sliding component 2, the steel coil 4 can enter the cooling pool immediately after the external processing process (such as rolling, heating, etc.), minimizing the time loss caused by waiting for cooling, realizing the continuity of the production process, and improving the overall production efficiency; the spray component 3 can evenly spray the coolant to ensure that the temperature distribution of the steel coil 4 during the cooling process is more uniform, reducing the internal stress caused by the temperature difference, thereby reducing quality problems such as deformation and cracks, ensuring the high consistency of the product and extending the service life.

[0037] To reduce the continuous waste of water flow in the spray pipe 31 and lower water consumption during the cooling process, in one embodiment, grooves 5 are evenly spaced on the track 21. A switch assembly 6 is disposed within the grooves 5. The switch assembly 6 comprises a T-bar 61 and a spring 62. The ends of the spring 62 are connected to the horizontal rod of the T-bar 61 and the inner bottom surface of the groove 5, respectively. When the horizontal rod of the T-bar 61 compresses the spring 62 downward, the water flow of the spray pipe 31 is opened. By providing the switch assembly 6 with the T-bar 61 and the spring 62, the system automatically controls the water flow of the spray pipe 31. When the skid 22 passes, the switch is automatically activated, turning on the spray system. When the skid 22 leaves, the spray system automatically turns off. This design simplifies the operation process, reduces manual intervention, and improves operational convenience and safety. The switch assembly 6 ensures that the spray pipe 31 sprays water only when the steel coil 4 passes through the spray zone. This on-demand water supply method reduces the continuous waste of water flow in the spray pipe 31 at other times, significantly reducing the water resource consumption during the cooling process; the spray pipe 31 only works when the steel coil 4 passes by, avoiding the waste of cooling energy and resources, while ensuring that each steel coil 4 can receive sufficient water spray during the cooling process, which helps to ensure the consistency and efficiency of the cooling effect.

[0038] In order to prevent water from being randomly scattered around the pool body 1 and causing pollution to the surrounding soil and water bodies, and to effectively monitor and control the amount of water used, in one embodiment, a water collection ditch 7 is provided on the pool body 1. The water collection ditch 7 is provided along the length of the pool body 1 and is used to divert and recycle the spray water. The water collection ditch 7 is responsible for collecting the spray water and ensuring that the used water can flow back into the system, which greatly reduces the demand for new water and realizes the effective utilization of water resources. The water collection ditch 7 can effectively monitor and control the amount of water used, thereby reducing the water cost and reflecting a more sustainable water management. The water collection ditch 7 concentrates and diverts the spray water to prevent water from being randomly scattered around the pool body 1 and causing pollution to the surrounding soil and water bodies. The water collection ditch 7 can quickly remove excess water and reduce the accumulation of water around the pool body 1, thereby preventing the occurrence of safety accidents such as slips and ensuring the safety of operators.

[0039] In order to effectively remove solid impurities in the water and achieve the reuse of recycled water, based on this, in one embodiment, a sedimentation tank 8 is further provided on one side of the tank body 1, and the water collection ditch 7 guides the spray water into the sedimentation tank 8. The sedimentation tank 8 allows the suspended matter and sediment in the spray water to naturally settle through gravity, thereby effectively removing solid impurities in the water and improving the quality of the recycled water; the sedimentation tank 8 allows the suspended matter and sediment in the spray water to naturally settle through gravity, thereby effectively removing solid impurities in the water and improving the quality of the recycled water; by directing the spray water into the sedimentation tank 8, the water after sedimentation can be reused, reducing dependence on fresh water, thereby achieving water recycling and reducing overall water consumption; the setting of the sedimentation tank 8 provides a centralized platform for water quality monitoring and treatment, which can monitor water quality changes in real time and take necessary treatment measures.

[0040] In order to facilitate the subsequent use and management of recycled water and provide a stable water source for different processes, in one embodiment, a clear water tank 9 is further provided in the sedimentation tank 8, and a water pump 32 pumps the clear water in the sedimentation tank 8 into the clear water tank 9 for storage. The provision of the clear water tank 9 can effectively centrally store the clear water after sedimentation treatment, facilitating subsequent use and management, and helping to improve the water resource utilization efficiency of the entire system; the stored clear water can be reused at different stages as needed, such as for spraying, cooling or other process requirements, thereby reducing the consumption of fresh water and improving the recycling rate of water; since the sedimentation tank 8 may cause water quality fluctuations due to drainage from different processes, the clear water tank 9 can act as a buffer to ensure that the system can still provide a stable water source even when the water quality changes.

[0041] In order to remove suspended matter, impurities, and pollutants from the recycled water and improve the quality of the spray water, in one embodiment, a filter plate 10 is provided on the upper cover of the water collection ditch 7. The filter plate 10 is used to filter impurities in the spray water. The filter plate 10 is configured as a double layer. The double-layer filter plate 10 can form two filter layers, so that impurities in the water can be captured at different levels, improving the overall filtration effect. Coarse impurities are intercepted in the first layer, and fine impurities are further filtered in the second layer. The double-layer filtration design can evenly distribute the pressure of the water flow on the two levels, thereby improving the overall filtration efficiency and extending the service life of the filter plate 10. Through double-layer filtration, suspended matter, impurities, and pollutants in the water can be removed more efficiently, thereby improving water quality and providing a cleaner foundation for subsequent sedimentation and the water source of the clear water tank 9. Better water quality not only helps to improve cooling efficiency, but also helps protect equipment by preventing water quality problems from affecting cooling effects and production flow.

[0042] In order to reduce the power requirement for the movement of the sliding car 22 and improve the heat exchange efficiency between the steel coil 4 and the cooling water, based on this, in one embodiment, the upper end surface of the sliding car 22 is set as a slope with high sides and low middle, and the steel coil 4 is placed in the two sets of slopes in a rolling manner. The design of the slope allows the steel coil 4 to move on the sliding car 22 in a rolling manner rather than sliding. This rolling contact has less friction resistance than sliding friction, thereby reducing the power requirement for the movement of the sliding car 22; due to the reduction in movement resistance, the required motor power is correspondingly reduced, thereby reducing energy consumption and improving the overall system energy efficiency; the slope design allows the steel coil 4 to roll evenly under the action of the cooling water spray, thereby increasing the contact area between the steel coil 4 and the cooling water, improving the heat exchange efficiency, and allowing the steel coil 4 to obtain a uniform cooling effect in a shorter time.

[0043] In order to reduce the resistance of the steel coil 4 when rolling and reduce the load on the motor, based on this, in one embodiment, a mounting groove 11 is concavely provided on the slope of the upper end surface of the sliding vehicle 22, and a roller 12 is rollingly installed in the mounting groove 11. The setting of the roller 12 enables the steel coil 4 to move on the sliding vehicle 22 mainly by rolling. The roller 12 bears the pressure and rotates, which significantly reduces the contact friction between the steel coil 4 and the slope. Compared with the sliding friction caused by direct contact, this friction is smaller, which is conducive to reducing energy consumption. Due to the presence of the roller 12, the actual contact surface area is relatively reduced, which reduces the resistance of the steel coil 4 when rolling, thereby making the sliding process smoother and reducing the load on the motor. The installation of the roller 12 can reduce the direct contact between the steel coil 4 and the slope, reduce the wear of each component, and the smaller friction also means that the overall life of the equipment is extended, the frequency and cost of maintenance are reduced, and the reliability of the entire system is improved.
