[0004] Some existing steel plate cooling devices are usually composed of a frame, a water collecting tank, a cooling bin, a conveyor, a cooling mechanism and the like. The spraying part in the cooling mechanism sprays cooling water on the steel plate to achieve the cooling effect, and the water supply part is responsible for providing cooling water to the spraying part.

Although this method can remove the water on the surface of the steel plate to some extent, due to its low drying efficiency, it often takes a long time to achieve the desired drying effect. This not only increases the production cycle, but also may increase energy consumption.

DETAILED DESCRIPTION

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0035] The cooling device for steel plate production provided in the embodiments of the present application can solve the problem that the steel surface is left with water stains after the use of the existing steel plate cooling mechanism in the related art and the low efficiency of single hot air drying.

[0036] Please refer to Figures 1-3 A cooling device for steel plate production comprises a frame body 1, a water collecting tank 2 and a cooling bin 3 are sequentially arranged on the frame body 1 from bottom to top, a conveyor 4 is arranged in the cooling bin 3 and used for conveying steel plates, a plurality of drainage holes communicating with the water collecting tank 2 are formed in the bottom of the cooling bin 3, a cooling mechanism 5 is arranged on the frame body 1, the cooling mechanism 5 comprises a spraying part 51 arranged above the cooling bin 3 and a water supply part 52 arranged in the frame body 1 and used for supplying cooling water to the spraying part 51, the spraying part 51 is used for spraying cooling water on the steel plates, a water scraping mechanism 6 is arranged in the cooling bin 3, the water scraping mechanism 6 comprises side water scraping parts 61 arranged on the two sides of the cooling bin 3 and a top water removing part 62 arranged in the cooling bin 3 and above the conveyor 4, and a drying unit 7 is arranged on the cooling bin 3 and used for air cooling the steel plates.

[0037] The steel plates to be cooled are placed on the conveyor 4, and the conveyor 4 starts to work and slowly sends the steel plates into the cooling bin 3.

[0038] When the steel plate enters the cooling bin 3, the cooling mechanism 5 starts to work. The water supply part 52 provides cooling water to the spraying part 51, which uniformly sprays the cooling water on the steel plate. After the cooling water contacts the steel plate, it quickly takes away the heat on the steel plate, achieving rapid cooling.

[0039] After spraying cooling, a certain amount of cooling water will remain on the surface of the steel plate. At this time, the water scraping mechanism 6 starts to work. The side water scraping part 61 and the top water removing part 62 are respectively located on both sides and above the steel plate, and remove the residual water on the surface of the steel plate by scraping and extruding. The scraped water flows into the water collecting tank 2 through the drain hole at the bottom of the cooling bin 3, realizing the centralized collection and subsequent treatment of water.

[0040] Finally, the steel plate after water scraping and water removal enters the action range of the drying unit 7. The drying unit 7 blows wind to the surface of the steel plate to accelerate the evaporation of the residual water on the surface of the steel plate, realizing the drying treatment of the steel plate.

[0041] Uniformly spraying the cooling water on the steel plate by the spraying part 51 can quickly take away the heat on the steel plate, achieving efficient cooling. The setting of the water scraping mechanism 6 can effectively remove the residual water on the surface of the steel plate, reduce the formation of water stains, and improve the appearance quality of the steel plate.

[0042] Through the water collecting tank, the cooling bin 3, the cooling mechanism 5, the water scraping mechanism 6 and the drying unit 7, multiple functions such as cooling, water scraping, drainage and drying can be integrated, realizing the automation and continuity of the steel plate cooling treatment, and improving the production efficiency.

[0043] Collecting the scraped water into the water collecting tank 2 through the drain hole can realize the recycling of water resources and reduce the waste of water resources.

[0044] The cooling bin 3 in the embodiment is a U-shaped box body, both ends and the top of which are open; the conveyor 4 is distributed along the length of the cooling bin 3, and both ends thereof extend to the outside.

[0045] The cooling bin 3 is a U-shaped box body structure, both ends and the top of which are open, so that the steel plate can smoothly enter the inside of the cooling bin 3 from the conveyor 4 for cooling treatment, and can be conveniently output after the treatment. The open design also facilitates the maintenance and cleaning of the inside of the cooling bin 3.

[0046] The conveyor 4 is distributed along the length direction of the cooling bin 3, which means that the steel plate can be continuously cooled in the cooling bin 3 without interrupting the conveying. In addition, both ends of the conveyor 4 extend to the outside, so that the steel plate has enough space for buffering and continuous conveying before entering the cooling bin 3 and after leaving the cooling bin 3, thereby ensuring the stability and continuity of the steel plate conveying.

[0047] The U-shaped cooling bin 3 is combined with the extended conveyor 4 to form an efficient and continuous steel plate cooling system, which improves the efficiency of the steel plate cooling process and makes the entire process more automated and continuous, reducing manual intervention and downtime, thereby reducing production costs.

[0048] In one embodiment, the spraying part 51 includes a fixed frame arranged on the frame body 1, and a water supply pipe 511 is arranged above the fixed frame. The water supply pipe 511 is provided with a plurality of valves at one end, and a metal hose 512 is arranged at the other end of the valves. The other end of the metal hose 512 is provided with a spray head 513 located above the cooling bin 3.

[0049] The fixed frame is firmly installed on the frame body 1, providing stable support for the water supply pipe 511. The water supply pipe 511 serves as a transmission channel for cooling water. At one end of the water supply pipe 511, a plurality of valves are arranged to control the flow and on / off state of the cooling water, so as to adjust the spraying effect according to actual needs.

[0050] The metal hose 512 is a flexible pipe connecting the valves and the spray head, which has good flexibility and corrosion resistance, and can adapt to different directions and angles of spraying requirements.

[0051] The spray head 513 is located above the cooling bin 3 and is the component that directly contacts the steel plate with the cooling water. In this embodiment, the spray head 513 may use a mist or fine rain spraying method to improve the cooling efficiency and reduce water stains.

[0052] In summary, the spraying part 51 can achieve uniform and efficient cooling of the steel plate. At the same time, it is also convenient to maintain and adjust the spraying system to adapt to the cooling needs of steel plates of different specifications and materials.

[0053] In one embodiment, the water supply part 52 includes a water supply tank 521 arranged above the frame body 1. A pump body 522 is arranged above the water supply tank 521. The water inlet of the pump body 522 is in communication with the water supply tank 521, and the water outlet of the pump body 522 is in communication with the water supply pipe 511.

[0054] The water supply tank 521 serves as a storage container for cooling water and is arranged on the frame body 1 to ensure sufficient supply of cooling water during continuous operation.

[0055] The pump body 522 serves as the power source of the water supply part. The water inlet of the pump body 522 is in communication with the inside of the water supply tank 521, so that the pump body 522 can extract cooling water from the water supply tank. The water outlet of the pump body 522 is in communication with the water supply pipe 511 to deliver pressurized cooling water to the spraying part 51. The selection of the pump body should consider factors such as the flow and pressure of the cooling water and the overall energy consumption of the system to ensure that the pump body can work stably and efficiently.

[0056] The water supply pipe 511 serves as a transmission channel for cooling water. In this embodiment, one end of the water supply pipe 511 is connected to the water outlet of the pump body 522, and the other end is connected to the multiple spray heads of the spraying part 51. The water supply pipe 511 can also be provided with valves, flow meters and other accessories inside to accurately control the flow and pressure of the cooling water.

[0057] During the cooling process, the pump body 522 extracts cooling water from the water supply tank 521, pressurizes it and delivers it to the water supply pipe 511. The cooling water in the water supply pipe 511 is then distributed to the multiple spray heads of the spraying part 51, which uniformly sprays the steel plate. The sprayed cooling water drips from the surface of the steel plate and is collected in the water collecting tank 2.

[0058] In one embodiment, the water supply tank 521 is provided with a partition 11 inside, which divides the water supply tank 521 into a backwater chamber 8 and a cooling water chamber 9. The water outlet of the pump body 522 is connected to the cooling water chamber 9. The water collecting tank 2 is connected to multiple recovery pipes 10 at the bottom, and the other end of the recovery pipes 10 is connected to the backwater chamber 8. A filter screen is provided between the partition 11 and the water supply tank 521, and two drain valves are provided on the water supply tank 521. The two valves are connected to the backwater chamber 8 and the cooling water chamber 9 respectively. The recovered water is filtered by the filter screen and then discharged through the corresponding valve.

[0059] The water supply part 52 and its integration with the backwater system aim to realize the recycling of cooling water, which not only improves the utilization rate of water resources, but also ensures the stability and durability of the cooling system.

[0060] The water supply tank 521 is one of the core components of the entire cooling system, and its interior is divided into two independent spaces, the backwater chamber 8 and the cooling water chamber 9, by the partition 11. The backwater chamber 8 is used to collect the cooling water flowing back from the cooling chamber 3, while the cooling water chamber 9 stores the cooling water that has been treated and is ready to be used for spraying again. The pump body 522 serves as the power source of the water supply part, and its water outlet is directly connected to the cooling water chamber 9, ensuring that the cooling water can be stably and continuously delivered to the spraying part 51 under pressure.

[0061] The water collecting tank 2 serves as a cooling water collecting device, and its bottom is connected to multiple recovery pipes 10. These recovery pipes 10 guide the cooling water collected in the water collecting tank 2 to the backwater chamber 8, realizing the recycling of cooling water.

[0062] In order to further improve the quality and recycling efficiency of the cooling water, a filter screen is provided between the partition 11 and the water supply tank 521. The filter screen can effectively intercept and remove impurities and particulate matter in the cooling water.

[0063] In addition, two drain valves are arranged on the water supply tank 521, which are respectively connected with the return water cavity 8 and the cooling water cavity 9, so as to conveniently drain the accumulated water in the cooling water cavity 9 or perform cleaning and maintenance, and meanwhile, the cooling water filtered in the return water cavity 8 can be transported, cooled in an external cooling pool and then sent into the cooling water cavity 9 for recycling or other uses.

[0064] In one embodiment, the side scraping member 61 comprises a mounting plate 611 arranged on the cooling bin 3, and a scraping plate 612 is inserted into the mounting plate 611 near one side of the conveyor 4.

[0065] The main function of the side scraping member 61 is to remove the excess cooling water attached to the side of the steel plate.

[0066] The mounting plate 611 is firmly arranged on the side wall of the cooling bin 3 as the main support structure of the side scraping member, and is usually made of corrosion-resistant and high-strength metal or alloy materials to withstand mechanical stress and chemical corrosion during the scraping process.

[0067] The scraping plate 612 is the key working component of the side scraping member, which is inserted into the mounting plate 611 near one side of the conveyor 4. The design of the scraping plate 612 needs to consider the close fit with the side of the steel plate to ensure that the cooling water attached thereto can be effectively scraped off. The scraping plate is usually made of wear-resistant and corrosion-resistant materials such as rubber or polyurethane to prolong the service life and maintain the scraping effect.

[0068] The insertion design between the scraping plate 612 and the mounting plate 611 makes the scraping plate convenient to install and disassemble, which not only facilitates the replacement and maintenance of the scraping plate, but also allows the position of the scraping plate to be adjusted according to actual needs to ensure the best scraping effect. The insertion design usually includes an insertion slot and an insertion block structure to ensure the firm connection between the scraping plate and the mounting plate.

[0069] During the cooling process, when the conveyor 4 drives the steel plate to pass through the cooling bin 3, the excess cooling water attached to the side of the steel plate will be scraped off by the scraping plate 612 of the side scraping member. The scraped-off cooling water then drips into the water collecting tank 2 below.

[0070] In one embodiment, the top water removal device 62 includes a fixed block 621 arranged oppositely inside the cooling bin 3, and a support block 622 arranged at the bottom of the fixed block 621, and a rotating disc 623 rotatably arranged on one side of the support block 622, and a water absorption roller 624 connected by bolts between the two rotating discs 623; an electric push rod 625 is arranged above the fixed block 621, and the piston rod of the electric push rod 625 penetrates the fixed block 621 and is connected with the rotating disc 623. A through hole is formed in the fixed block 621 for the extension of the piston rod, and two arc-shaped patches are oppositely arranged at one end of the rotating disc 623, and one end of the water absorption roller 624 is inserted between the two arc-shaped patches and fixed by bolts.

[0071] The top water removal device 62 is designed to effectively remove the excess cooling water remaining on the upper surface of the steel plate, so as to improve the cooling effect.

[0072] The fixed block 621 serves as the main support structure of the top water removal device, and is oppositely arranged inside the cooling bin 3 to ensure the stability and reliability of the installation. The material of the fixed block 621 is usually selected from corrosion-resistant and high-strength metal or alloy materials to withstand mechanical stress and chemical corrosion during the water removal process.

[0073] The support block 622 is used to support the rotating disc 623 and the water absorption roller 624. The rotating disc 623 is rotatably arranged on one side of the support block 622 to connect and support the water absorption roller 624.

[0074] The water absorption roller 624 is a key working component of the top water removal device, and is connected by bolts between the two rotating discs 623. The design of the water absorption roller needs to consider its water absorption performance and wear resistance to ensure that it can effectively remove the excess cooling water on the surface of the steel plate. The water absorption roller is usually made of materials with strong water absorption and good wear resistance, such as sponge, polyurethane foam, etc.

[0075] The piston rod of the electric push rod 625 penetrates the fixed block and is connected with the rotating disc 623. Through the extension and retraction movement of the electric push rod, the gap between the water absorption roller 624 and the steel plate can be easily adjusted to ensure the best water removal effect. The through hole formed in the fixed block 621 is used for the extension of the piston rod to ensure that the electric push rod can work normally.

[0076] The two arc-shaped patches at one end of the rotating disc 623 are used to fix one end of the water absorption roller 624. One end of the water absorption roller is inserted between the two arc-shaped patches and fixed by bolts, so that the water absorption roller can be firmly connected to the rotating disc, and it is convenient to disassemble and replace.

[0077] During the cooling process, when the steel plate passes through the cooling bin 3, the water absorption roller 624 is in contact with the surface of the steel plate, and the excess cooling water on the surface of the steel plate is removed through rotation and extrusion. The electric push rod 625 can adjust the height of the water absorption roller according to the thickness of the steel plate to ensure the best water removal effect. The removed cooling water then drips into the water collecting tank 2 below.

[0078] In one embodiment, the drying unit 7 includes a shell 71 arranged above the cooling bin 3, a plurality of fans 72 are arranged opposite to each other on the shell 71, and an electric heating rod 73 is arranged inside the shell 71 below the fans 72. The shell is U-shaped, hollow inside, and open at both ends. A plurality of ventilation nets are embedded opposite to each other on the cooling bin 3 below the shell 71

[0079] The drying unit 7 quickly removes the residual moisture on the surface of the steel plate through forced convection and heating, ensuring that the steel plate will not rust or have other quality problems due to moisture during subsequent processing or storage.

[0080] The shell 71 is designed in a U-shape, hollow inside, and open at both ends, so that the shell 71 can cover the upper part of the cooling bin 3, forming a relatively closed space, which is conducive to the forced convection of the fan and the heat radiation of the heating rod. The material of the shell 71 is usually a metal or alloy material with high strength and corrosion resistance to ensure its stability and reliability during long-term use.

[0081] A plurality of fans 72 are arranged opposite to each other on the shell 71 to generate forced convection and accelerate the evaporation of moisture on the surface of the steel plate. In this embodiment, the fan can be a centrifugal fan or an axial flow fan, and the specific type needs to be determined according to the actual use scene and drying requirements.

[0082] The electric heating rod 73 is arranged inside the shell 71 below the fans 72. The electric heating rod 73 increases the temperature inside the shell 71 through heating to accelerate the evaporation of moisture on the surface of the steel plate. In this embodiment, the electric heating rod uses resistance wire heating or ceramic heating, and the specific type needs to be determined according to the actual use scene and heating requirements.

[0083] A plurality of ventilation nets are embedded opposite to each other on the cooling bin 3 below the shell 71. The design of the ventilation net allows the hot air and humid air inside the shell to exchange with the inside of the cooling bin 3 through the ventilation net, thereby accelerating the drying process of the steel plate. The material and aperture of the ventilation net need to consider its ventilation performance and corrosion resistance to ensure that it will not be clogged or damaged during long-term use.

[0084] During the drying process, the fan 72 is started to generate forced convection, blowing hot air in the shell 71 to the surface of the steel plate to accelerate the evaporation of moisture on the surface of the steel plate. At the same time, the electric heating rod 73 heats to increase the temperature in the shell, further enhancing the drying effect. The hot air and wet air are exchanged with the inside of the cooling bin through the ventilation net to form a circulating air flow, ensuring the continuity and efficiency of the entire drying process.
