Description

Technical Field

[0001] The present invention relates to the technical field of conveying pipelines, and in particular to a nylon titanium dioxide slurry conveying pipeline and a conveying system. Background Art

[0002] Nylon titanium dioxide slurry conveying pipelines and conveying systems are key equipment used to convey titanium dioxide slurry in the nylon production process. The conveying system mainly includes conveying pipelines, pumps, stirring devices, filtering devices and control systems. The conveying pipelines can use hoses, which can absorb a certain degree of vibration and noise. During the slurry conveying process, the impact of vibration and noise generated by pump operation and slurry flow on the surrounding environment can be reduced, which is conducive to improving the working environment. The hoses are made of special materials, such as polytetrafluoroethylene (PTFE) lined hoses, which have excellent corrosion resistance and can well resist the erosion of chemical substances that may exist in nylon titanium dioxide slurry, thereby extending the service life of the pipelines.

[0003] However, when the existing nylon titanium dioxide slurry conveying pipeline and conveying system are in use, the conveying pipeline is exposed to the outside and is easily bumped and scratched. At the same time, the conveying pipeline is easily contaminated and corroded by impurities such as air and water stains, resulting in defects such as cracks on its surface, affecting its conveying effect and life; during transportation, the solid particles in the titanium dioxide slurry are easily deposited on the inner wall of the conveying pipeline, which is difficult to clean, affecting the conveying effect. At the same time, the solid particles in the titanium dioxide slurry have a wear effect on the inner wall of the pipeline, especially when the particle hardness is high or the flow rate is fast, the wear is more obvious. The pipeline wear will cause the pipe wall to become thinner, or even perforation and leakage, which is not easy to be discovered in time and is not safe and reliable enough.

[0017] The nylon titanium dioxide slurry conveying pipeline and conveying system are provided with a connecting mechanism and a driving mechanism. When it is necessary to clean the solid particles accumulated on the inner wall of the hose, the fourth motor is started. The rotation of the fourth motor drives the rotation of the winding wheel, which can reel in the pull rope, thereby pulling the first movable ring to move along the side wall of the hose toward the fixed ring. At the same time, the second spring and the telescopic tube are compressed. At this time, the circular ring and the second movable ring can be driven to move synchronously through the connecting mechanism, and the reserved curved portion can be pushed to gradually move toward the fixed ring. In addition, the second motor is started and the second motor is driven. The rotation of the machine drives the rotation of the gear, thereby driving the gear ring and the connecting ring to rotate, and then driving the circular ring and the second movable ring to rotate through the connecting mechanism. At this time, the reserved curved portion can rotate with the rotation of the circular ring, and so on. The hose can be swung and bent in all directions, which is convenient for cleaning solid particles accumulated on the inner wall, ensuring its conveying effect and service life. At the same time, the first motor can be started, and the rotation of the first motor drives the rotation of the second rotating pin and the rotating plate, thereby adjusting the angle of the rotating plate, and then adjusting the bending degree of the reserved curved portion, so that the cleaning effect is better.

[0018] The nylon titanium dioxide slurry conveying pipeline and conveying system is provided with a detection mechanism, etc. When the circular ring moves along the side wall of the hose toward the fixed ring, the third motor is started, and the rotation of the third motor drives the rotation of the rubber wheel, thereby driving the rotating ring to rotate. When the rotating ring rotates, the reset mechanism can drive the moving rod and the third ball to rotate synchronously, and make the third ball roll along the outer wall of the hose. At this time, the ultrasonic thickness sensor can detect the wall thickness of the hose and can detect in time when the inner wall of the hose is seriously worn. At the same time, the first visual sensor can detect defects such as cracks on the surface of the hose, and during the detection process, the hose is in a bent state. The curved state makes the detection effect better, safer and more reliable, and when the third ball rolls on the surface of the hose, when the third ball is out of round, the third ball and the moving rod will move relative to the rotating ring. At this time, it can drive the disc to resist the side wall of the V-block, thereby pushing the slider to move along the guide rail in the direction away from the moving rod. At the same time, it drives the push rod to slide along the slide groove, which can push the pointer to rotate clockwise along the rotating shaft. The second visual sensor detects the scale on the scale plate indicated by the pointer to determine the degree of out of roundness, and an external alarm is used to remind the operator to perform inspection, maintenance and replacement to ensure its conveying effect and service life.
