Description

Technical Field

[0001] This utility model relates to a device for blowing air to remove water and cool down steel plates after they have been straightened by a hot straightening machine, and belongs to the technical field of hot straightening equipment for steel plates. Background Technology

[0002] A hot straightening machine is a device used to correct shape defects in plastically processed metal products (such as medium-thick plates) at high temperatures (generally 650~1000℃), and it is one of the important finishing processes. The working principle of a hot straightening machine is to utilize the plasticity of the metal sheet at high temperatures, and gradually straighten the sheet by applying certain pressure and bending force. External cooling water for the roller system of the hot straightening machine plays a crucial role in ensuring the normal operation of the straightening machine, improving straightening accuracy, and enhancing steel plate quality. External cooling water effectively reduces the temperature of the straightening roller system, preventing equipment damage or performance degradation caused by high temperatures. Simultaneously, the external cooling water prevents thermal deformation of the straightening rollers due to high temperatures, thus ensuring straightening accuracy and steel plate quality. External cooling water also protects the roller surface, preventing a decrease in roller surface hardness and scratches caused by high temperatures. However, currently, after using external cooling water for the roller system and closing the external cooling water supply valve, some cooling water remains in the pipes and roller system. As a result, when the steel plate is straightened, the water will fall onto the plate, causing pits to form on the plate surface, which seriously affects the surface quality of the steel plate. At the same time, there is no cooling device inside the hot straightening machine, which affects the stable operation and service life of the hot straightening machine. It is necessary to make improvements to ensure the quality of the straightened steel plate. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a water removal and cooling device for a hot straightening machine for steel plates. This water removal device can remove the cooling water remaining in the pipeline and roller system, avoid pits on the surface of the steel plate during the straightening process, improve the quality of the steel plate, and at the same time cool down the hot straightening machine and roller conveyor to ensure the stable operation of the hot straightening machine and extend the service life of the hot straightening machine.

[0004] The technical solution to the above technical problem is:

[0005] A dewatering and cooling device for a hot straightening machine for steel plates includes an air inlet main pipe, an inlet and outlet main pipe, spray pipes, nozzles, an air inlet pipe, an air inlet valve, a water inlet pipe, a drain pipe, a water inlet valve, and a drain valve. The air inlet main pipe and the inlet and outlet main pipes are horizontally placed on both sides of the hot straightening machine. Multiple parallel spray pipes are connected between the air inlet main pipe and the inlet and outlet main pipes. The multiple spray pipes pass through the side walls of the hot straightening machine and are vertically connected to the air inlet main pipe and the inlet and outlet main pipes. Multiple nozzles are installed on the multiple spray pipes and are opposite to the roller conveyor inside the hot straightening machine. The air inlet main pipe is connected to the air inlet pipe, which is connected to a compressed air pipeline. An air inlet valve is installed on the air inlet pipe.

[0016] This utility model consists of an air intake main pipe 1, an air intake and drainage main pipe 2, a spray pipe 3, a nozzle 4, an air intake pipe 5, an air intake pipe valve 6, a water intake pipe 7, a drainage pipe 8, a water intake pipe valve 9, and a drainage pipe valve 10.

[0017] Figure 1 , 2 The air intake main pipe 1 is horizontally placed on one side of the hot straightener 12. Its function is to input compressed air into the hot straightener 12 to blow away water. The air intake main pipe 1 is vertically connected to multiple parallel nozzles 3, which are located inside the hot straightener 12. Each nozzle 3 is equipped with multiple nozzles 4, which are positioned opposite the roller conveyor 11 inside the hot straightener 12. The air intake main pipe 1 is connected to an air intake pipe 5, which is connected to a compressed air pipeline. An air intake valve 6 is installed on the air intake pipe 5. Compressed air is ejected from the nozzles 4 of the nozzles 3 through the air intake pipe 5 and the air intake main pipe 1. The nozzles 4 blow the compressed air onto the roller conveyor 11, removing water from the roller conveyor 11 and preventing pits from appearing on the surface of the steel plate during the straightening process.

[0018] Figure 1 , 2 The inlet and outlet main pipe 2 is located on the other side of the hot straightener 12. Its function is to supply water to and drain water from the hot straightener 12, thus cooling it. The inlet and outlet main pipe 2 is parallel to the air inlet main pipe 1 and is perpendicularly connected to the other side of the multiple nozzles 3 that pass through the hot straightener 12. The inlet and outlet main pipe 2 is connected to the water inlet pipe 7 and the drain pipe 8, respectively. A water inlet valve 9 is installed on the water inlet pipe 7, and the inlet end of the water inlet pipe 7 is connected to the cooling water pipe. A drain pipe valve 10 is installed on the drain pipe 8, and the lower end of the drain pipe 8 is opposite to a water collection tank or drainage pool.

[0019] Figure 1 , 2The display shows that the outlet end of the inlet pipe 7 is connected to the main inlet and outlet pipe 2. The inlet pipe valve 9 is installed at the inlet end of the inlet pipe 7, and the inlet pipe valve 9 can control the water intake of the inlet pipe 7. The inlet end of the outlet pipe 8 is connected to the inlet pipe 7 in front of the inlet pipe valve 9. Thus, after closing the inlet pipe valve 9, opening the outlet pipe valve 10 can drain the water stored in the main inlet and outlet pipe 2 from the outlet pipe 8.

[0020] Figure 3 , 4 The display shows that multiple nozzles 3 are located between multiple upper rollers 11 inside the hot straightener 12, and multiple nozzles 4 are installed on both sides of the nozzles 3, with each nozzle 4 facing the rollers 11 on either side of the nozzles 3. The nozzles 3 and nozzles 4 have the dual functions of blowing air to remove water and spraying water to cool the surface. Compressed air is blown onto the rollers 11 through the nozzles 4 of the nozzles 3 to remove water stored on the rollers 11, which can prevent pits from appearing on the surface of the steel plate during the straightening process. At the same time, the main inlet and outlet pipes 2 can deliver cooling water to the nozzles 3, and the cooling water is sprayed onto the rollers 11 of the hot straightener 12 through the nozzles 4 to cool the surface, which can ensure the quality of the steel plate.

[0021] The usage process of this utility model is as follows:

[0022] After the steel plate passes through the cooling control device, the position sensor detects the cooling and sends an electrical signal to close the water inlet valve 9, stopping the cooling water from entering the main inlet and outlet pipe 2. At the same time, the air inlet valve 6 and the drain valve 10 are opened, allowing compressed air to enter the nozzle 3 through the main air inlet pipe 1. The compressed air is then sprayed onto the roller conveyor 11 through the nozzle 4 of the nozzle 3, preventing cooling water from remaining in the pipes and roller system. After the air blowing is completed, the steel plate is straightened, which can prevent pits from appearing on the surface of the steel plate during the straightening process and ensure the quality of the steel plate.

[0023] After the steel plate is straightened and leaves the hot straightener 12, the position sensor detects it and sends an electrical signal, which sequentially closes the air inlet valve 6 and the drain valve 10, stopping the compressed air from entering the main air inlet pipe 1; at the same time, the water inlet valve 9 is opened, allowing cooling water to enter the main water inlet and drain pipe 2 through the water inlet pipe 7 and reach the spray pipe 3. The nozzles 4 of the spray pipe 3 spray water to cool the hot straightener 12 and the roller system, ensuring the stable operation of the hot straightener and improving its service life.

[0024] After cooling is complete, close the inlet valve 9 and open the drain valve 10 to allow the cooling water remaining in the spray pipe 3 to be discharged from the drain pipe 8. The discharged cooling water can be recycled into the collection tank or drainage pool.
