Description

Technical Field

[0001] The utility model relates to the technical fields of hot rolling, anti-fogging and detectors, in particular to an anti-fogging device for a hot steel detector. Background Art

[0002] Winters in the north are cold. During hot rolling production, cooling water is needed to cool the rollers, rolling grooves, guides and other process parts. When the water vapor is cooled, a large amount of water mist is generated, resulting in a lot of fog in the factory. Sometimes the fog fills the entire factory, and the workers have to walk by feeling. During production, an infrared detector is needed to detect the temperature of hot steel or the real-time position information of hot steel. However, this fog blocks the infrared radiation radiated by the hot steel, affecting the stability of the signal collection using infrared acquisition equipment, resulting in misoperation of the subsequent execution equipment that needs automatic control, resulting in various production accidents and even affecting the quality of the finished product. In order to solve this problem, various units are trying to find a solution, but the effect is not ideal.

[0003] Existing anti-fog solutions generally meet the following conditions: keep the detector at a certain distance from the hot steel, use a metal cover to protect it from damage, and install a detection channel between the hot metal and the detector to prevent fog from blocking it. However, existing anti-fog solutions have the following disadvantages:

[0004] 1. When there is fog in winter, add an axial flow fan directly behind the detector to blow air into the protective cover to disperse the fog. This method is suitable for working environments with less fog and the fan position is not covered by fog. If there is fog at the fan position, then the fog will also be blown into the cover, affecting the detection effect;

[0005] Second, to avoid signal instability caused by greater fog, make the protective cover longer to form a very long ventilation duct, try to lead it to the edge of the factory where there is no fog, and then put an axial flow fan with a diameter of 1000mm inside to supply air. This can improve a lot. When fog fills the entire factory, it still cannot solve the fundamental problem. Although this situation rarely occurs, and this structure is too large, it seriously occupies other equipment installation positions and personnel maintenance work space;

[0006] 3. Instead of using a fan to supply air, compressed air is used to blow air into the protective cover, which solves the problem of no clean air source when the fog is heavy. However, when the compressed air is blown into the protective cover, it also brings in more or less nearby fog, which affects the detection effect and is difficult to determine the cause.

[0007] The above three methods all supply air to the protective cover from the rear. Because the hot rolling mill has high dust and humidity, turbulence is formed near the detector mirror when air is supplied. Long-term turbulence will cause dust to adhere to the mirror, affecting the passage of light and causing occasional accidents. Therefore, it is necessary to clean frequently to keep the lens clean.

One side of the moving ring 1 is hinged with one end of a connecting rod 13, and a plug connector arranged on the other end of the connecting rod 13 is plugged into a plug hole provided on the first fixing ring 12, and the first fixing ring 12 is fixedly connected to the connecting pipe 11, and the connecting pipe 11 is fitted with the other side of the housing 4, and a second fixing ring 14 is fixedly connected to the connecting pipe 11, and a plug-in ring 18 is fixedly connected to the second fixing ring 14, and the plug-in ring 18 is plugged into a limiting groove provided on a limiting seat 17, and the limiting seat 17 is fixedly connected to the supporting ring 15, and a detection tube 10 is fixedly connected to the connecting pipe 11, and an air supply pipe 8 is embedded and installed on the detection tube 10, and one end of the air supply pipe 8 is fixedly connected to a nozzle 9, and the nozzle 9 is located in the detection tube 10, and the other end of the air supply pipe 8 is fixedly connected to a connector 7;

[0026] Specifically, when in use, first, adjust the distance between the nozzle 9 and the hot steel, then connect it to the compressed air transport pipe through the provided connector 7, and then spray the compressed air through the nozzle 9 to complete the jet treatment of the hot steel. In the process of jetting, the provided detector 5 is used to complete the detection of the hot steel. In the process of detection, the shape of the detection tube 10 can be changed according to the shape of the hot steel, so that in the process of jetting, the jetting work can be completed according to the shape of the hot steel, and the detection accuracy is improved at the same time. In actual work, the device can be adjusted according to actual needs, and the adjustment process includes: 1. The window distance of the detection tube 10: The distance from the hot steel should be minimized while ensuring the normal operation of the hot steel to prevent the compressed air from blowing over and forming a foggy vortex in the middle to block the infrared propagation due to the large distance; 2. The window size and shape of the detection tube 10: According to the different operating ranges of the target to be detected, the detection window shape of the detection tube 10 also changes accordingly. It is generally a rectangular cross-section. The detection window should cover the maximum range of the detection target. At the same time, under the premise that the detector allows the minimum detection area, the window cross-section should be minimized to facilitate the use of the minimum amount of compressed air for demisting and ensure the stability of the detection target signal; 3. The distance between the nozzle 9 and the hot steel: The end of the compressed air nozzle is installed in the middle section between the detector 5 and the hot steel. And it is close to the detection target (hot steel), the shape of the nozzle 9 should match the window of the detection tube 10, so that the air coming out of the nozzle can cover the entire window of the detection tube 10, and the flow rate can be adjusted in conjunction with the compressed air pipeline valve to allow the mist between the hot steel and the window of the detection tube 10 to be blown away at any time. If it is installed near the detector 5 or farther away, the compressed air blown out of the nozzle will form a vortex in front of the 5 lens, and the dust and water vapor in the air will adhere to the lens, affecting the light transmission, resulting in unstable signals; Fourth, the size of the detection tube 10: Determine the distance between the detector 5 and the hot steel according to the on-site environmental conditions and the use conditions of the detector 5, and the size of the detector 5 according to this distance And the subsequent installation, inspection, and repair of the detector 5 determine the overall size of the detection tube 10, and the size and shape of the channel between the detector 5 and the hot steel are determined: mainly to ensure that the normal propagation of the infrared rays of the hot steel is not blocked; 5. The production requirements of the shell 4: the shell 4 must have sufficient strength to prevent damage in the event of a production accident or other accident, which will affect the normal operation of the detector 5. When installing the air supply pipe 8, signal line and side door 6, the airtightness of the shell 4 and the detection tube 10 should be ensured as much as possible. Because when the compressed air is blown out, a negative pressure is formed in the shell 4. The sealed shell 4 prevents external fog and dust from entering the cover, affecting the cleanliness of the lens of the detector 5, thereby reducing the intensity of maintenance.
