Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of inspection robots, in particular to an inspection robot for air tightness detection of pneumatic chute pipelines. BACKGROUND

[0002] The pneumatic chute pipeline is a special conveying device, mainly used for bulk conveying of dry, loose and easily fluidized powdery materials. The pneumatic chute pipeline is a device that uses wind power (low pressure and small capacity air provided by a fan) to fluidize and convey materials in the pipeline. The device is usually divided into a lower air charging layer, a middle air permeable layer and an upper material conveying layer. The air provided by the fan enters the air permeable layer through the air charging layer, fluidizes the material, and then flows along the inclined direction of the pipeline under the action of gravity, realizing the conveying of the material. The air tightness detection of the pneumatic chute pipeline is an important link to ensure its normal operation and prevent material leakage. The air tightness detection of the pneumatic chute pipeline aims to verify the sealing performance of the pipeline to ensure that gas leakage or material leakage does not occur during use, thereby improving the quality and safety of the product, reducing energy waste and environmental pollution. However, the existing air tightness detection of the pneumatic chute pipeline requires manual operation, and the air tightness detection method used may not be accurate enough, and is mostly only suitable for preliminary detection, and the air tightness position detected is not accurate enough.

The trend of the meter is used to judge the damage or blockage of the pneumatic pipeline. The inspection moving slide 1 moves and adjusts at the bottom of the moving guide rail 16 to adjust the detection position of the high-definition camera 18 and the infrared thermal imager 20. The output end of the first motor 9 drives the adjusting lead screw 8 to rotate. When the adjusting lead screw 8 rotates, the outer adjusting sliding block 7 moves and adjusts.

The infrared thermal imager 20 completes the air tightness detection of the pneumatic chute pipeline body 32. The infrared thermal imaging of the alumina conveying pipeline is performed. After analyzing the imaging results, the results are transmitted back to the background monitoring center for display. Real-time abnormal atlas is alarmed. Through the inspection of the pneumatic chute pipeline body 32, the infrared atlas of the pipeline is formed. The system can automatically save the atlas data to form the limit interval parameter and diversified analysis report for the diagnosis and analysis of the operation and maintenance personnel. If obvious mutations are found, the operation and maintenance personnel will receive prompt information for manual checking. Because the thermal capacity of the blocked part is different from that of other parts, the temperature difference is transmitted to the pipeline shell. The infrared thermal imager 20 can be applied to the outside of the pneumatic chute pipeline body 32 to shoot the fault.The gas and aluminum powder flowing through the pneumatic chute pipeline body 32 have different temperatures from normal temperature, and temperature abnormalities can occur at the leakage position, which can be directly detected by the infrared thermal imager 20. In the joint and turning position of the pneumatic chute pipeline body 32, the gas or liquid erosion can cause partial thinning, thereby causing leakage. The infrared thermal imager 20 is used to detect these areas. Pressure gauges 33 are installed at intervals in the pneumatic chute pipeline body 32 to sense the real-time pressure in the pneumatic chute pipeline body 32. The leakage of the pneumatic chute pipeline body 32 can be inferred according to the values of these pressure gauges 33. The principle is to rely on the meter reading capability of the robot. Finally, all the pressure gauges 33 arranged on the pneumatic chute pipeline body 32 are trend calculated, and the trend of the meter is used to judge the damage or blockage of the pneumatic chute pipeline body 32.
