Description

Technical Field

[0001] This utility model relates to the field of stainless steel sheet production technology, and in particular to a cooling device for processing stainless steel sheets. Background Technology

[0002] With the rapid development of the stainless steel sheet processing industry, the demand for cooling during welding processes is increasing. During stainless steel sheet welding, the welding heat effect can easily cause changes in the physical and mechanical properties of the welded area and its surrounding region. Therefore, effective cooling of the welding heat effect zone is necessary. Traditional cooling methods typically use liquid nitrogen or other cooling media, but in practical applications, these methods suffer from high energy consumption, high cost, and uneven cooling, making it difficult to meet the demands of modern stainless steel sheet processing for efficient, energy-saving, and precise cooling.

[0003] Existing stainless steel sheet cooling devices have several shortcomings in practical applications. For example, traditional cooling devices often employ a single cooling method, making it difficult to adjust the cooling strategy according to the different thicknesses of stainless steel sheets, resulting in unsatisfactory cooling effects. For thin sheets, due to their structural characteristics, uneven cooling can easily cause sheet deformation, affecting processing quality; while for thick sheets, traditional cooling methods may not be able to effectively control the cooling rate, leading to low cooling efficiency and potentially negatively impacting sheet quality. Furthermore, existing devices suffer from high energy consumption and high maintenance costs during the cooling process, failing to meet the requirements of modern industry for high efficiency, energy saving, and stable operation. Therefore, there is an urgent need for a cooling device that can flexibly adjust the cooling method according to the thickness differences of stainless steel sheets, while also possessing high efficiency, energy saving, precise temperature control, and stable operation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling device for stainless steel sheet processing. The device uses a vortex tube cooling end combined with a shaped metal flexible hose for cooling, achieving 50% energy savings. It offers two cooling methods depending on the sheet thickness: spray cooling for thin sheets to prevent deformation, and water tank cooling for thick sheets. The water tank has an L-shaped filter for easy cleaning, ensuring stable operation of the device and reducing costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for processing stainless steel sheets, comprising a processing table, a vortex tube fixedly connected to the upper left side of the processing table, a shaped metal flexible tube fixedly connected to the cold air end of the vortex tube, a water trough opened at the upper right side of the processing table, a conveying roller rotatably connected to the inner wall of the water trough, side plates fixedly connected to the front and rear sides of the upper end of the processing table, a spray head fixedly connected to the upper end of the side plates, a sliding groove opened at the right end of the processing table, an L-shaped filter screen slidably connected to the inner wall of the sliding groove, rotating plates provided on the right sides of both the front and rear ends of the L-shaped filter screen for fixing the L-shaped filter screen, a water tank fixedly connected to the right side of the processing table, and arc-shaped surfaces provided on both the left and right ends of the inner wall of the water tank.

[0006] Furthermore, the lower end of the rotating plate is rotatably connected to the inside of the processing table, and the upper end of the rotating plate is fixedly connected to the upper end of the processing table by a snap fastener.

[0007] Furthermore, an air intake pipe is fixedly connected to the left end of the vortex tube, a control valve is fixedly connected to the middle of the air intake pipe, and an air compressor is fixedly connected to one end of the air intake pipe.

[0008] Furthermore, a temperature sensor is provided on the outer wall of the conveying roller to detect the temperature of the plate.

[0009] Furthermore, the right end of the water trough passes through the processing table and is sloped to the right.

[0010] Furthermore, the horizontal plane of the L-shaped filter screen is lower than the bottom plane of the water tank.

[0011] Furthermore, a processing device is provided on the right side of the vortex tube, and the lower end of the processing device is fixedly connected to the upper end of the processing table.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this invention, the cooling method using a vortex tube cooling end combined with a shaped metal flexible hose offers significant advantages in small-area, high-precision cooling scenarios. Specifically for areas such as the welding heat effect zone during stainless steel sheet processing, it achieves energy savings of up to 50% compared to traditional liquid nitrogen cooling, significantly reducing energy consumption and production costs. Simultaneously, by flexibly adjusting the compressed air input through a control valve, it can precisely match the critical cooling rate requirements of different stainless steel grades, ensuring that the cooling effect meets process requirements while avoiding negative impacts on sheet quality due to improper cooling. This achieves a precise combination of cooling process control and high-efficiency energy saving.

[0014] 2. In this utility model, the device is designed with two cooling methods based on the thickness differences of stainless steel plates. For thin plates, spray cooling is used, with a temperature sensor monitoring and controlling the spray head flow distribution in real time to effectively prevent plate deformation caused by uneven cooling and ensure the processing quality of thin plates. For thick plates, the plates are directly conveyed to a water tank for cooling. The curved surface of the water tank acts as a guide and buffer, allowing the plates to enter the water tank smoothly. In addition, the L-shaped filter screen equipped in the water tank can intercept impurities in the mist and is easy to clean. Simply open the buckle, rotate the rotating plate, and slide out the filter screen to remove impurities, preventing them from entering the water tank. This ensures the long-term stable operation of the device and reduces equipment failures and maintenance costs caused by impurity accumulation. Attached Figure Description

[0022] 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.

[0023] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of a cooling device for processing stainless steel sheets, comprising a processing table 1, a vortex tube 2 fixedly connected to the upper left side of the processing table 1, an air inlet pipe 3 fixedly connected to the left end of the vortex tube 2, a control valve 4 fixedly connected to the middle of the air inlet pipe 3, an air compressor 5 fixedly connected to one end of the air inlet pipe 3, a shaped metal flexible hose 6 fixedly connected to the cold air end of the vortex tube 2, and a processing device 17 arranged on the right side of the vortex tube 2, the lower end of the processing device 17 fixedly connected to the upper end of the processing table 1. A water trough 7 is provided on the upper right side. A conveyor roller 8 is rotatably connected to the inner wall of the water trough 7. The right end of the water trough 7 passes through the processing table 1 and is sloped to the right. A temperature sensor is provided on the outer wall of the conveyor roller 8 to detect the temperature of the board. Side plates 9 are fixedly connected to the front and rear sides of the upper end of the processing table 1. A spray head 10 is fixedly connected to the upper end of the side plates 9. A slide 16 is provided on the right end of the processing table 1. An L-shaped filter screen 15 is slidably connected to the inner wall of the slide 16. The horizontal height of the L-shaped filter screen 15 is lower than the bottom height of the water trough 7.

[0024] Specifically, when processing stainless steel sheets using this device, different cooling methods are employed for sheets of varying thicknesses: When processing stainless steel sheets at processing equipment 17, the air compressor 5 is first started, allowing compressed air to enter the vortex tube 2 through the inlet pipe 3. The cold air end of the vortex tube 2 blows cold air onto the stainless steel sheet through a shaped metal hose 6, thus achieving cooling. During this process, the input of compressed air is adjusted using the control valve 4 to meet the critical cooling rate required for different stainless steel grades. This cooling setup is particularly suitable for small-area, high-precision cooling scenarios, such as welding heat effect zones, and can save 50% energy compared to traditional liquid nitrogen cooling. If the stainless steel sheet is thin, it is conveyed to the spray area via conveyor rollers 8. Spray heads 10 spray mist to cool the sheet, preventing deformation due to improper cooling. Simultaneously, a temperature sensor monitors the sheet temperature in real time, and the flow distribution of the spray heads 10 is controlled based on the monitoring results to ensure uniform cooling. The mist generated during the cooling process flows to the right end of the water trough 7 and eventually enters the water tank 11. L-shaped filter 15 is used to intercept impurities in the mist.

[0025] Reference Figure 1 , Figure 3 and Figure 4 The L-shaped filter screen 15 has rotating plates 14 on both the front and rear right sides to fix the L-shaped filter screen 15. The lower end of the rotating plate 14 is rotatably connected to the inside of the processing table 1, and the upper end of the rotating plate 14 is fixedly connected to the upper end of the processing table 1 by a buckle 13. A water tank 11 is fixedly connected to the right side of the processing table 1, and the inner wall of the water tank 11 has arc-shaped surfaces 12 on both the left and right sides.

[0026] Specifically, when cleaning impurities, first open the latch 13, then rotate the rotating plate 14 90 degrees around its bottom, and then slide the L-shaped filter screen 15 out to the right, removing it along with the intercepted impurities to prevent them from entering the water tank 11. When the stainless steel plate is thick, the device uses direct water cooling, controlling the conveyor roller 8 to transport the plate into the water tank 11 for cooling. The arc-shaped surface 12 of the water tank 11 acts as a guide and buffer when the plate enters the water tank 11, ensuring a smooth cooling process.

[0027] Working Principle: When using this device, stainless steel sheets are processed at processing equipment 17. Air compressor 5 is started, and compressed air is input into vortex tube 2 through intake pipe 3. The cold air end of vortex tube 2 cools the stainless steel sheet through a shaped metal hose 6. Control valve 4 controls the input amount of compressed air to adapt to the critical cooling rate requirements of different stainless steel grades. This setup is suitable for small-area, high-precision cooling, such as welding heat effect zones, and saves 50% more energy than traditional liquid nitrogen cooling. When the stainless steel sheet is thin, it is conveyed to the spray zone by conveying roller 8. Spray head 10 sprays mist to cool the sheet, preventing deformation. A temperature sensor detects the sheet temperature, thereby controlling the flow distribution of the spray head 10 to prevent uneven cooling. The resulting mist flows to the right through water trough 7 and finally enters water tank 11, where L-shaped filter 15 intercepts impurities. By opening the latch 13 and then rotating the rotating plate 14, causing the rotating plate 14 to rotate 90 degrees around its bottom end, the L-shaped filter screen 15 can slide out to the right, carrying away the intercepted impurities and preventing them from entering the water tank 11. When the stainless steel plate is thick, the conveying roller 8 is directly controlled to convey the plate into the water tank 11 for cooling, and the arc-shaped surface 12 acts as a guide and buffer.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
