Description

Technical Field

[0001] This utility model relates to the field of cooling bed technology, specifically a spray-type cooling bed device. Background Technology

[0002] In the metal processing industry, especially in the steel production process, the cooling bed is an extremely important piece of equipment, undertaking the key task of cooling hot-rolled steel. The stepping rack of the cooling bed needs to be effectively cooled, and its cooling effect is directly related to the quality of the steel and the production efficiency.

[0003] However, existing cooling bed devices still have some problems in use:

[0004] First, existing cooling bed cooling methods generally use natural cooling and water spray cooling. Natural cooling has a slow cooling speed, while water spray cooling has a high power consumption of the circulating water pump during long-term operation, a high dependence on water resources, and the steel profiles are prone to uneven cooling and severe rusting.

[0005] Secondly, existing cooling bed cooling devices lack a structure that allows for flexible adjustment of the cooling height, making it impossible to adjust the distance between the nozzles and the bottom of the cooling bed according to actual conditions. Inappropriate spacing will also affect the cooling effect of the device. Utility Model Content

[0006] In order to solve the problems of poor cooling effect and lack of flexible structural design for adjusting the cooling height in existing cooling bed devices, the purpose of this utility model is to provide a spray-type cooling bed device.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: a spray-type cooling bed device, including a base, a support plate above the base, a lifting mechanism between the base and the support plate, a spray-type cooling component on the upper surface of the support plate, the spray-type cooling component including a centrifugal fan, the centrifugal fan being fixedly installed on the upper surface of the support plate, a duct being fixedly connected to the output end of the centrifugal fan, exhaust vertical pipes being connected at equal intervals on the upper surface of the duct, a nozzle being connected to the top end of the exhaust vertical pipe, a water pump being fixedly installed on the upper surface of the support plate, a delivery pipe being connected to the output end of the water pump, a water pipe being connected to the end of the delivery pipe facing away from the water pump, connecting pipes being connected at equal intervals on one side of the water pipe, and one end of the corresponding connecting pipe being connected to the corresponding nozzle.

[0008] Preferably, the lifting mechanism includes a hydraulic lifting rod, which is fixedly installed on the upper surface of the base. The output end of the hydraulic lifting rod is fixedly connected to the lower surface of the support plate. A guide cylinder is fixedly connected to the upper surface of the base in a rectangular array, and a guide rod is fixedly connected to the lower surface of the support plate in a rectangular array. The corresponding guide rod is slidably connected to the guide cylinder.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This application uses a spray-type cooling component to fully mix and atomize air and water before spraying it onto the surface of the profile. Through efficient heat exchange, rapid cooling is achieved. This cooling method not only has high cooling efficiency but also ensures uniform surface temperature of the profile, avoiding deformation caused by excessive local temperature differences. Compared with traditional water spray cooling, it significantly reduces water consumption, effectively saves water resources, significantly improves the appearance quality and performance of the profile, and greatly enhances the overall cooling effect of the cooling bed cooling device.

[0011] 2. This application, through a lifting mechanism, can flexibly and precisely adjust the distance between the nozzle and the bottom surface of the cooling bed according to the specifications and cooling requirements of different profiles. This not only enables the profiles to receive more suitable cooling treatment, but also effectively cools the stepping rack of the cooling bed, ensuring the cooling effect of its cooling device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figure 1-3 As shown, this utility model provides a spray-type cooling bed device, including a base 1, a support plate 4 above the base 1, and a lifting mechanism 3 between the base 1 and the support plate 4. The lifting mechanism 3 can adjust the height of the support plate 4, thereby flexibly adjusting the distance between the spray-type cooling component 2 and the cooling bed to adapt to the cooling requirements of different profile specifications and ensure the cooling effect. The upper surface of the support plate 4 is provided with the spray-type cooling component 2, which sprays air and water into atomized form and onto the surface of the profile. Through efficient heat exchange, rapid cooling is achieved, greatly enhancing the overall cooling effect of the cooling bed device.

[0019] The spray cooling component 2 includes a centrifugal fan 22, which is fixedly installed on the upper surface of the support plate 4. The output end of the centrifugal fan 22 is fixedly connected to a duct 25. The centrifugal fan 22 provides a stable airflow through the duct 25, providing aerodynamics to the spray cooling component 2, so that the air and water are fully mixed and atomized at the nozzle 202, thereby improving the cooling efficiency. The outer surface of the duct 25 is equipped with multiple temperature sensors 23, which monitor the air temperature inside the duct 25 in real time and provide temperature data to the operator. The outer surface of the duct 25 is equipped with an airflow regulating valve 21 that works with the centrifugal fan 22. The airflow regulating valve 21 can flexibly adjust the airflow output by the centrifugal fan 22, and adjust the air-water mixing ratio according to the cooling requirements of different profiles, so as to achieve precise control of the cooling speed and effect.

[0020] The upper surface of the air duct 25 is provided with exhaust vertical pipes 24 at equal intervals. The top of the exhaust vertical pipe 24 is provided with nozzles 202. The exhaust vertical pipes 24 distribute the air in the air duct 25 evenly to each nozzle 202. With the equal intervals, the uniformity of the cooling area is ensured. The nozzles 202 are key components for mixing and atomizing air and water, and spray the mixed atomized fluid onto the surface of the profile to achieve efficient cooling.

[0021] A water pump 27 is fixedly installed on the upper surface of the support plate 4. A suction pipe 26, which is a flexible hose, is connected to the end of the water pump 27 facing away from the delivery pipe 28. The suction pipe 26 draws coolant through the water pump 27. The flexible suction pipe 26 can be flexibly arranged to facilitate the extraction of coolant from different locations, providing a stable water supply for spray cooling. The output end of the water pump 27 is connected to the delivery pipe 28. A water pipe 29 is connected to the end of the delivery pipe 28 facing away from the water pump 27. Connecting pipes 201 are connected at equal intervals on one side of the water pipe 29. The delivery pipe 28, water pipe 29, and connecting pipe 201 are all stainless steel pipes. One end of the corresponding connecting pipe 201 is connected to the corresponding nozzle 202. The stainless steel conveying pipe 28, water pipe 29 and connecting pipe 201 are corrosion resistant and have high strength, ensuring the stability and sealing of the coolant during the delivery process and extending the service life of the device. The pipes are interconnected, and the coolant drawn by the water pump 27 is stably delivered to the nozzle 202 to ensure the normal operation of the spray cooling component 2. The nozzle 202 is an air atomizing nozzle. The air atomizing nozzle 202 can fully mix air and coolant and atomize them into fine particles, increasing the contact area between the atomized fluid and the surface of the profile and improving the heat exchange efficiency.

[0022] The lifting mechanism 3 includes a hydraulic lifting rod 31, which is fixedly installed on the upper surface of the base 1. The output end of the hydraulic lifting rod 31 is fixedly connected to the lower surface of the support plate 4. The hydraulic lifting rod 31 provides a stable and powerful lifting driving force, which can precisely adjust the height of the support plate 4, thereby flexibly adjusting the distance between the spray cooling component 2 and the cooling bed to meet the cooling process requirements of different specifications of profiles and ensure the cooling effect.

[0023] The upper surface of the base 1 is fixedly connected to a rectangular array of guide cylinders 32, and the lower surface of the support plate 4 is fixedly connected to a rectangular array of guide rods 33. The guide rods 33 are slidably connected to the guide cylinders 32. The cooperation between the guide cylinders 32 and the guide rods 33 forms a stable guiding structure. When the hydraulic lifting rod 31 adjusts the height of the support plate 4, it effectively restricts the direction of movement, prevents the support plate 4 from shifting or shaking, and ensures the smoothness of the lifting process and the safety of the device operation.

[0024] Working principle: When it is necessary to cool the profiles on the cooling bed, first adjust the distance between the nozzle 202 and the bottom surface of the cooling bed according to the profile specifications or cooling process, start the lifting mechanism 3, the hydraulic lifting rod 31 is fixed on the upper surface of the base 1, and its output end pushes the support plate 4 to rise or fall. When the support plate 4 drives the spray cooling component 2 to rise or fall, the spray angle of the nozzle 202 can cover the cooling bed table and the stepping rack and other components below. During the lifting process, the guide cylinder 32 on the base 1 and the guide rod 33 under the support plate 4 slide together to ensure that the support plate 4 rises and falls smoothly, so that the spray cooling component 2 can be precisely adjusted in height to achieve all-round cooling of the profiles and cooling bed components.

[0025] Next, the centrifugal fan 22 and water pump 27 in the spray cooling component 2 are started. The airflow generated by the centrifugal fan 22 enters the air duct 25 through the output end. The exhaust vertical pipes 24 connected at equal intervals on the upper surface of the air duct 25 distribute the airflow evenly to the nozzles 202 at the top, which not only provides air power for the atomization of the coolant, but also accelerates the heat diffusion by blowing on the surface of the profile.

[0026] At the same time, the water pump 27 draws coolant from the external storage tank through the suction pipe 26 made of flexible hose, and delivers it to the nozzle 202 through the stainless steel delivery pipe 28, water pipe 29 and connecting pipe 201.

[0027] At nozzle 202, the structure of the air atomizing nozzle allows the airflow to be fully mixed with the coolant, atomized into fine particles and sprayed onto the profile surface. The coolant particles carry away heat through rapid evaporation, while the airflow of the centrifugal fan 22 accelerates the evaporation process, achieving efficient cooling. The equally spaced nozzles 202 ensure uniform cooling of the profile surface, avoiding quality problems caused by local temperature differences.

[0028] During the cooling process, the temperature sensor 23 on the outer surface of the duct 25 monitors the airflow temperature in real time. When the detected temperature is higher than the set threshold, the operator increases the airflow of the centrifugal fan 22 through the airflow regulating valve 21 to improve the atomization effect and airflow speed to enhance heat dissipation; if the temperature is lower than the threshold, the airflow is reduced to avoid overcooling. Through the linkage between temperature feedback and airflow regulation, the device can flexibly adapt to the cooling needs of different profiles.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
