Description

Technical Field

[0001] This utility model belongs to the field of flue gas detection technology, and in particular to a self-cleaning intelligent detection sensor for converter flue gas. Background Technology

[0002] The converter flue gas intelligent detection sensor is a device specifically designed for real-time monitoring of flue gas composition (such as...) during converter steelmaking. CO This is a high-precision automated detection device for parameters such as temperature, pressure, and dust concentration. It combines sensor technology, a self-cleaning system, and intelligent algorithms, enabling it to operate stably for extended periods in the harsh environment of converters, characterized by high temperatures, high dust levels, and strong corrosion. This provides crucial data support for steelmaking process optimization, energy recovery, and environmental emission control.

[0003] In converter steelmaking, flue gas monitoring is a crucial step in monitoring the smelting process, optimizing process parameters, and ensuring environmental compliance. However, converter flue gas is characterized by high temperature, high dust levels, and strong corrosiveness (containing CO, etc.). Traditional flue gas detection sensors, due to their characteristics such as dust accumulation, face serious technical bottlenecks in practical applications. In particular, the sensor's front-end probe is prone to clogging from dust, requiring frequent manual cleaning. Specifically, this manifests as follows: Traditional flue gas detection sensors (such as electrochemical sensors and laser scattering sensors) typically employ straight tube or open detection structures, with their front end directly exposed to the flue gas environment. Since converter flue gas contains a large amount of metal oxide dust and unburned carbon particles, these particles have extremely strong adhesion at high temperatures and are very easy to accumulate at the inlet of the detection tube, forming a dense dust layer.

[0004] The purpose of this invention is to provide a self-cleaning intelligent detection sensor for converter flue gas to solve the problems mentioned in the background art. Utility Model Content

[0016] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0017] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0018] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0019] Please see Figures 1 to 5As shown, a self-cleaning converter flue gas intelligent detection sensor includes a flue gas sensor body 1, which is an existing device and its working principle will not be described in detail here. A mounting box 2 is set on one side of the flue gas sensor body 1. An air inlet pipe 19 is provided between the mounting box 2 and the flue gas sensor body 1, and the air inlet pipe 19 is connected to the mounting box 2.

[0020] The first motor 4 is located on the top of the mounting box 2. The mounting box 2 contains a sliding box 8. A processing tube 9 for cleaning the inner wall of the air intake pipe 19 is located on one side of the sliding box 8. Limiting grooves 13 are symmetrically opened on the inner wall of the processing tube 9. A connecting plate 11 is provided at one end of the cleaning cylinder 10. The limiting groove 13 is used to limit the connecting plate 11. When the second screw 12 rotates, it can push the connecting plate 11 to move, thereby driving the cleaning cylinder 10 to move and extend into the air intake pipe 19 for cleaning. The connecting plate 11 is slidably connected in the limiting groove 13. The second screw 12 is threadedly connected to the connecting plate 11. The second screw 12 is provided on one side of the mounting box 2. The connecting post 14 extends out of the outside of the mounting box 2 and is connected to the second screw 12. The cleaning cylinder 10 is slidably connected inside the processing tube 9. A cleaning brush is provided on the outside of the cleaning cylinder 10. The cleaning brush is made of soft material and can freely enter and exit the processing tube 9.

[0021] The output end of the first motor 4 is provided with a drive unit for driving the processing tube 9 for cleaning. The drive unit includes a hub box set inside the sliding box 8. A connecting post 14 is set inside the hub box. A first helical gear 15 is set outside the connecting post 14. The first helical gear 15 is meshed with a second helical gear 16. A rotating ring 18 is set at the center of the second helical gear 16. A limit post 6 is set inside the rotating ring 18. The limit post 6 is connected to the output end of the first motor 4. Limit plates 17 are symmetrically set on both sides of the limit post 6. The limit plates 17 are slidably connected inside the rotating ring 18. The purpose of the rotating ring 18 is to prevent the meshing state of the first helical gear 15 and the second helical gear 16 from changing when the sliding box 8 moves up and down. The limit post 6 is rotatably connected inside the mounting box 2. The limit post 6 is also used to limit the sliding box 8, so that the sliding box 8 moves up and down under the rotation of the first screw 7.

[0022] The second motor 5 is located on the top of the mounting box 2. The output end of the second motor 5 is provided with a moving part for driving the sliding box 8 to move up and down. The moving part includes a first screw 7 located at the output end of the second motor 5. The first screw 7 is rotatably connected inside the mounting box 2. The first screw 7 is threadedly connected to the sliding box 8. An air inlet 3 is provided at the front end of the mounting box 2. The first motor 4 and the second motor 5 are both existing devices, and their working principles are well known to those skilled in the art. Their working principles will not be described in detail here.

[0023] Working principle: After the flue gas sensor body 1 completes its work, the second motor 5 is started. The second motor 5 drives the first screw 7 to rotate. Since the movement trajectory of the sliding box 8 is limited by the limiting post 6, the sliding box 8 is driven to move. When the processing tube 9 on one side of the sliding box 8 moves to the same height as the air inlet pipe 19, the first motor 4 at the top of the mounting box 2 is started. The first motor 4 drives the limiting post 6 to rotate, thereby the limiting plate 17 drives the rotating ring 18 to rotate, thereby driving the second helical gear 16 to rotate. The second helical gear 16 drives the first helical gear 15, which meshes with it, to rotate, thereby driving the connecting post 14 to rotate. The connecting post 14 drives the second screw 12 to rotate. Since the connecting plate 11 connected to the outside of the second screw 12 is slidably connected in the limiting groove 13, the connecting plate 11 is driven to move. The connecting plate 11 pushes the cleaning cylinder 10 forward into the air inlet pipe 19. When it extends, it can be pulled out from the air inlet 3 to clean the air inlet 3.
