DETAILED DESCRIPTION
[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.
[0031] The embodiments of the present application provide a drying device for a push-pull type pickling line, which can solve the problem of uneven heat distribution in the existing strip steel hot air drying equipment in the related art, leading to the problem of excessive drying in some areas of the strip steel and insufficient drying in some areas.
[0032] Please refer to Figures 1-5 A drying device for a push-pull type pickling line includes a drying bin 1, the drying bin 1 has a through hole 2 for strip steel feeding and discharging, and a drying mechanism 3 is arranged inside the drying bin 1; the drying mechanism 3 includes a guide frame 31 arranged inside the drying bin 1 and used for receiving the strip steel, a drying cylinder 32 arranged inside the drying bin 1 and sleeved outside the guide frame 31, a plurality of exhaust holes 321 are formed on the drying cylinder 32 for spraying hot air, a wiping box 33 arranged at one end of the guide frame 31 and used for adsorbing liquid on the surface of the strip steel, and an air supply pipe 34 arranged on the drying cylinder 32 and used for supplying hot air to the inside of the drying cylinder 32.
[0033] The strip steel enters the interior of the drying device through the through hole 2 on the drying bin 1. The through hole is designed to be large enough to ensure the smooth entry and exit of the strip steel while maintaining the sealing of the device.
[0034] The strip steel entering the drying bin is received by the internal guide frame 31. The guide frame 31 provides a stable support surface for the strip steel, allowing it to pass smoothly through the entire drying process.
[0035] After the strip steel enters the drying bin 1, it passes through the wiping box 33 set at one end of the guide frame 2, which is used to absorb the small amount of liquid remaining on the surface of the strip steel, ensuring complete drying of the strip steel.
[0036] As the strip steel moves, it passes through the drying cylinder 32 fitted outside the guide frame. The drying cylinder 32 is internally provided with a gas supply pipe 34 to provide continuous hot air to the interior of the drying cylinder 32. These hot gases are uniformly sprayed onto the surface of the strip steel through the exhaust holes 321 provided on the drying cylinder 32, thereby achieving rapid drying.
[0037] The uniform spraying of hot air through the exhaust holes 321 on the drying cylinder 32 achieves comprehensive and rapid drying of the surface of the strip steel. This drying method not only improves the drying efficiency, but also ensures uniform drying of the surface of the strip steel. Through the adsorption effect of the wiping box 33, the residual liquid on the surface of the strip steel can be further removed, improving the efficiency of the drying of the strip steel. This helps to improve the surface quality of the strip steel and its subsequent processing performance.
[0038] Specifically, the upper end of the drying bin 1 is open, the bottom of the drying bin 1 is provided with a collection bucket 4 for collecting residual liquid, and the bottom of the collection bucket 4 is provided with a liquid discharge valve.
[0039] The open upper end allows the strip steel to easily enter and exit the drying bin 1 without the need for complex feeding and discharging mechanisms, reducing the complexity and cost of the equipment.
[0040] At the same time, in order to collect and process residual liquid such as pickling liquid or moisture that may be generated during the drying process, a collection bucket 4 is provided at the bottom of the drying bin 1.
[0041] The collection bucket 4 is located at the bottom of the drying bin 1 and can collect residual liquid that drips or evaporates from the surface of the strip steel, preventing it from flowing everywhere and maintaining a clean working environment.
[0042] The bottom of the collection bucket 4 is provided with a liquid discharge valve, which can discharge the residual liquid when the collection bucket accumulates to a certain degree, facilitating subsequent processing.
[0043] In one embodiment, the guide frame 31 comprises two support rods 311 arranged oppositely inside the drying chamber 1, and a plurality of reinforcing ribs 312 are arranged between the two support rods 311; the two support rods 311 are located between the two through holes 2, and the top end of the support rod 311 and the bottom wall inside the through hole 2 are located at the same level.
[0044] The support rod 311 not only provides a stable support surface for the strip steel, but also ensures the smooth movement of the strip steel during the drying process.
[0045] In order to enhance the structural strength of the support rod 311 and prevent it from deforming or being damaged when bearing the weight of the strip steel and the impact of hot gas, a plurality of reinforcing ribs 312 are arranged between the two support rods 311.
[0046] The two support rods 311 are located between the two through holes 2, ensuring that the strip steel can smoothly enter and exit the drying chamber 1. At the same time, the top end of the support rod and the bottom wall inside the through hole 2 are located at the same level, so that the strip steel can maintain a stable posture when entering and exiting the drying chamber 1, avoiding the phenomenon of jolting or jamming caused by height difference.
[0047] Preferably, grooves 5 are also provided on the support rod 311, and a plurality of rollers 6 are rotatably arranged inside the grooves 5, with the top end of the roller 6 being located at the same level as the top end of the support rod 311.
[0048] A plurality of rollers 6 are rotatably arranged inside the grooves 5, ensuring that the strip steel can be uniformly and stably supported. The rollers are made of wear-resistant and high-temperature-resistant materials to adapt to the high-temperature environment and the weight of the strip steel that may be encountered during the drying process.
[0049] The top end of the roller 6 is located at the same level as the top end of the support rod 311, ensuring that the strip steel can smoothly transition during movement, avoiding the phenomenon of jolting or jamming caused by height difference. At the same time, the rotating characteristics of the roller greatly reduce the frictional resistance between the strip steel and the support rod 311, allowing the strip steel to pass through the drying chamber 1 more smoothly.
[0050] In one embodiment, the drying cylinder 32 has a cavity 323 inside for storing hot gas, and the bottom of the drying cylinder 32 is provided with a gap 322 for draining liquid; the exhaust hole 321 is arranged inside the drying cylinder 32, and the exhaust hole 321 communicates with the cavity 323.
[0051] The drying cylinder 32 has a cavity 323 inside for storing hot gas, and the cavity 323 is the main storage and distribution area of the hot gas. The hot gas enters the cavity 323 through the gas supply pipe 34, and then is uniformly sprayed onto the surface of the strip steel through the exhaust hole 321, achieving the drying effect.
[0052] In order to optimize the distribution of hot air, exhaust holes 321 are arranged in the interior of the drying cylinder 32 and communicate with the cavity 323. These exhaust holes are arranged in a ring shape on the surface of the drying cylinder 32 to ensure that the hot air can uniformly and sufficiently cover the surface of the strip steel, thereby improving the drying efficiency.
[0053] In addition, in order to enhance the liquid discharge capacity of the drying cylinder 32, a notch 322 is arranged at the bottom of the drying cylinder, which allows any liquid generated during the drying process, such as residual liquid dropped from the surface of the strip steel or water droplets generated by the condensation of hot air, to be smoothly discharged, thereby preventing the accumulation of liquid inside the drying cylinder 32 and affecting the distribution of hot air and the drying effect. At the same time, the arrangement of the notch also facilitates the cleaning and maintenance of the drying cylinder.
[0054] In one embodiment, the wiping box 33 comprises a frame plate 331 connected with the support rod 311, and the inside of the frame plate 331 is clamped with drying cotton 332. The drying cotton 332 is in a rectangular frame shape, the other end of the frame plate 331 is connected with the drying bin 1, and the bottom wall inside the drying cotton 332 is at the same level as the bottom wall inside the through hole 2, and the inside dimension of the drying cotton 332 is matched with the inside dimension of the through hole 2.
[0055] The frame plate 331 provides a stable support structure for the wiping box 33 and ensures reliable connection between the wiping box 33 and the drying bin 1 and the support rod 311.
[0056] The inside of the frame plate 331 is clamped with drying cotton 332, which is a commonly used water-absorbing material with excellent moisture absorption and water retention properties, and can effectively absorb residual liquid on the surface of the strip steel. In this embodiment, the drying cotton 332 is designed in a rectangular frame shape to match the shape and size of the strip steel, thereby ensuring the best absorption effect.
[0057] In addition, the other end of the frame plate 331 is connected with the drying bin 1, which ensures that the wiping box 333 can be stably fixed inside the drying bin 1 and will not shake or fall off during the movement of the strip steel.
[0058] At the same time, the bottom wall inside the drying cotton 332 is at the same level as the bottom wall inside the through hole 2, and the inside dimension of the drying cotton 332 is matched with the inside dimension of the through hole 2, which ensures that the strip steel can maintain a stable posture when passing through the wiping box 33, avoiding the phenomenon of jolting or jamming caused by height difference or size mismatch.
[0059] In the present embodiment, one end of the gas supply pipe 34 communicates with the cavity 323, and the other end of the gas supply pipe 34 communicates with the external hot air supply pipeline.
[0060] The air supply pipe 34 is a component connecting the external hot air supply pipe with the internal cavity 323 of the drying cylinder 32. The other end of the air supply pipe 34 communicates with the external hot air supply pipe, ensuring continuous and stable supply of hot air, providing necessary heat energy for the drying process.
[0061] The collecting hopper 4 in the embodiment is provided below with a support.
[0062] The device is supported by the support, so that the device is kept at the same height as the pickling tank, maintaining the continuity of the production equipment.
