Description

Technical Field

[0001] This utility model relates to the field of galvanizing production technology, and in particular to a high-span steering roller cooling device with a wind box filter cleaning function. Background Technology

[0002] The high-span guide rollers in steel plate galvanizing production lines have a roller surface length of 1500mm and a diameter ranging from 700-1500mm, depending on the production line configuration. They are generally made from high-strength steel plates through processes such as rolling, surface quenching, and chrome plating. They are installed on a high-span platform 30-50 meters above the ground above the zinc pot. Since the steel strip exits the zinc pot at around 500 degrees Celsius, its temperature drops to around 300 degrees Celsius as it passes over the high-span guide rollers due to the upward airflow. Because of the unit speed, the high-span guide rollers are prone to generating high temperatures.

[0003] Existing high-span steering roller cooling equipment typically uses dustproof mesh panels to isolate dust from the external environment during long-term operation, protecting internal components from contamination. While this method effectively reduces the risk of dust entering the equipment, it also introduces another problem: over time, these dustproof mesh panels themselves gradually accumulate a large amount of dust. This dust accumulation not only reduces the air permeability of the mesh panels, affecting airflow efficiency and potentially weakening the cooling effect, but also increases wind resistance, potentially leading to increased energy consumption. Furthermore, excessively thick dust layers can become a breeding ground for microorganisms, further exacerbating equipment maintenance difficulties and making it inconvenient to use. Therefore, we propose a high-span steering roller cooling equipment with a windbox filter cleaning function, which is user-friendly and urgently needs development. Utility Model Content

[0004] The purpose of this utility model is to provide a high-span turning roller cooling device with a wind box filter cleaning function, which can avoid the problem that the dustproof mesh plate of the existing high-span turning roller cooling device will accumulate a lot of dust after long-term operation, resulting in reduced air permeability, reduced air circulation efficiency, weakened cooling effect, and increased energy consumption.

[0005] This utility model provides a high-span steering roller cooling device with a wind box filter cleaning function, including a wind box. The outer surface of the wind box is provided with a cleaning assembly. The cleaning assembly includes a fixing plate. The bottom of the fixing plate is fixedly connected to the top of the wind box. A threaded rod is rotatably connected to the outer surface of the fixing plate. Two symmetrically arranged cleaning plates are threadedly connected to the outer surface of the threaded rod, and the outer surfaces of the cleaning plates are slidably connected to the outer surface of the wind box.

[0006] In one specific implementation, a duct is fixedly connected to the front side of the air box, an arc-shaped plate is fixedly connected to the outer surface of the air box, a louver is installed in the inner cavity of the arc-shaped plate, and one end of the duct passes through the inner cavity of the arc-shaped plate and is used in conjunction with the louver.

[0007] In one specific implementation, a dustproof mesh plate is slidably connected to the rear side of the inner cavity of the air box, the dustproof mesh plate is used in conjunction with the cleaning plate, and a fan is installed in the inner cavity of the air box.

[0008] In one specific implementation, the inner cavity of the bellows is rotatably connected to two long rods arranged symmetrically at the top and bottom, the outer surface of the bellows is fixedly connected to a protective box, and the inner cavity of the protective box is bolted to a motor.

[0009] In one specific implementation, one end of the threaded rod extends to the outside of the fixed plate, and one end of the long rod extends to the outside of the bellows and is connected to the output shaft of the motor.

[0010] In one specific implementation, pulleys are respectively installed at one end of the threaded rod and the long rod, and the two pulleys are connected by belt drive. Several symmetrically arranged cams are fixedly connected to the outer surface of the long rod.

[0011] In one specific implementation, slide plates are slidably connected to both sides of the inner cavity of the bellows, and a connecting block is fixedly connected to the front side of the slide plate, with the outer surface of the connecting block in contact with the outer surface of the cam.

[0012] In one specific implementation, a fixed plate is fixedly connected to both sides of the inner cavity of the bellows, and a push rod is fixedly connected to the outer surface of the sliding plate. The rear end of the push rod extends through to the outside of the fixed plate and is fixedly connected to the outer surface of the dustproof mesh plate.

[0013] In one specific implementation, a return spring is sleeved on the outer surface of the push rod, and the two ends of the return spring are fixedly connected to the outer surfaces of the fixed plate and the sliding plate, respectively.

[0014] The beneficial effects of this application are as follows: the cleaning components can effectively and regularly clean the dustproof mesh plates in the high-span turning roller cooling equipment. This not only removes the dust accumulated on the surface of the dustproof mesh plates in a timely manner, but also improves the overall heat dissipation efficiency of the equipment. The cleaning components ensure that the dustproof mesh plates remain clean during long-term use, avoiding problems such as reduced air permeability, poor air circulation, and weakened cooling effect caused by dust accumulation. In addition, regular cleaning helps reduce additional wind resistance caused by dust, thereby reducing energy consumption. More importantly, keeping the dustproof mesh plates clean and tidy can prevent the growth of microorganisms, reduce the frequency and difficulty of maintenance, extend the service life of the equipment, and also ensure the safety and stability of the equipment operation.

[0022] Existing high-span steering roller cooling equipment suffers from dust accumulation on its dustproof mesh after prolonged operation, leading to reduced air permeability, decreased airflow efficiency, weakened cooling effect, and increased energy consumption. Therefore, the inventors have developed a high-span steering roller cooling device with an integrated airbox filter cleaning function. By incorporating a cleaning component, the dustproof mesh of the high-span steering roller cooling equipment can be periodically cleaned, effectively removing accumulated dust, improving heat dissipation efficiency, and thus resolving the aforementioned defects.

[0023] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] Please refer to Figures 1 to 5This utility model embodiment provides a high-span steering roller cooling device with a wind box filter cleaning function, including a wind box 1. A cleaning assembly 2 is provided on the outer surface of the wind box 1. Welded plates are fixedly connected to both sides of the wind box 1. The outer surface of the welded plates has through holes for easy installation. The cleaning assembly 2 includes a fixing plate 21. The bottom of the fixing plate 21 is fixedly connected to the top of the wind box 1. A threaded rod 22 is rotatably connected to the outer surface of the fixing plate 21. The outer surface of the threaded rod 22 has two oppositely arranged external threads. Two symmetrically arranged cleaning plates 23 are threadedly connected to the outer surface of the threaded rod 22. The area in contact with the threaded rod 22 is provided with a matching internal thread, and the outer surface of the cleaning plate 23 is slidably connected to the outer surface of the air box 1. Dust outlet cavities matching the cleaning plate 23 are provided on both sides of the air box 1. A duct 3 is fixedly connected to the front of the air box 1; the duct 3 is tapered. An arc-shaped plate 4 is fixedly connected to the outer surface of the air box 1. A louver 5 is installed inside the arc-shaped plate 4, and the louver 5 works in conjunction with the cleaning assembly 2. One end of the duct 3 passes through the inner cavity of the arc-shaped plate 4 and works in conjunction with the louver 5. A dustproof mesh plate 24 is slidably connected to the rear side of the inner cavity of the air box 1, and the dustproof mesh plate 24 works in conjunction with the cleaning plate 23. For combined use, a fan 25 is installed inside the air box 1, which works in conjunction with the air duct 3. Two long rods 26 arranged symmetrically vertically are rotatably connected to the inner cavity of the air box 1. A protective box 27 is fixedly connected to the outer surface of the air box 1, and a motor 28 is bolted to the inner cavity of the protective box 27. One end of the threaded rod 22 passes through to the outside of the fixed plate 21, and one end of the long rod 26 passes through to the outside of the air box 1 and is connected to the output shaft of the motor 28. A pulley 29 is installed at one end of the threaded rod 22 and the long rod 26, and the two pulleys 29 are connected by belt drive. Several symmetrically arranged... The cam 210 has a sliding disk 211 slidably connected to both sides of the inner cavity of the bellows 1. A connecting block 212 is fixedly connected to the front side of the sliding disk 211, and the outer surface of the connecting block 212 contacts the outer surface of the cam 210. A fixed disk 213 is fixedly connected to both sides of the inner cavity of the bellows 1. A push rod 214 is fixedly connected to the outer surface of the sliding disk 211. The rear end of the push rod 214 extends through to the outside of the fixed disk 213 and is fixedly connected to the outer surface of the dustproof mesh plate 24. A return spring 215 is sleeved on the outer surface of the push rod 214, and the two ends of the return spring 215 are fixedly connected to the outer surfaces of the fixed disk 213 and the sliding disk 211, respectively.

[0025] Specifically, during the cleaning operation, the motor 28 is started, and its output shaft drives the long rod 26 to rotate. The long rod 26 not only causes the threaded rod 22 to rotate through the pulley 29, but also drives the cam 210 to rotate. The threaded rod 22 operates based on the threaded transmission mechanism, causing the two cleaning plates 23 to reciprocate along the outer surface of the dustproof mesh plate 24, thereby removing the dust accumulated on it.

[0026] Furthermore, at the same time, as the cam 210 rotates, it applies pressure to the connecting block 212, thereby compressing the return spring 215. This process also simultaneously propels the push rod 214, ultimately causing the dust screen 24 to move slightly toward the sweeping plate 23. This allows the dust screen 24 to vibrate slightly during the sweeping process, enhancing the relative movement between it and the sweeping plate 23, effectively improving dust removal efficiency and ensuring its cleaning effect.

[0027] In summary, the working principle of the high-span turning roller cooling device with air box filter cleaning function according to this utility model embodiment is as follows: The user first installs the air box 1 near the high-span turning roller, and then needs to bring the arc plate 4 into contact with the high-span turning roller. When dissipating heat, the fan 25 is started to transmit the airflow to the louvers 5, and then the airflow is applied to the outer surface of the high-span turning roller through the louvers 5 to dissipate heat. When the dustproof mesh plate 24 has been used for too long, the cleaning component 2 is started to centrally remove dust from the dustproof mesh plate 24, thereby improving the heat dissipation efficiency and making it easy to use.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
