Description

Technical Field

[0001] The utility model relates to the technical field of pipeline anti-blocking, and specifically to a pipeline anti-blocking device. Background Art

[0002] Chemical production processes, air or sewage treatment systems, and other systems use a large number of pipes to transport gases, liquids, or fluids containing solid particles. The connecting pipes at different stages often have many bends or reductions due to factors such as site size, cost, and layout. During actual operation, fluids such as air or sewage may carry large solid foreign matter or large-sized material particles. When flowing through these bends or reductions, the solid foreign matter can easily accumulate and cause blockages, ultimately increasing the load on the pump. Furthermore, once a pipe becomes clogged, it is difficult to locate and clear the blockage.

[0003] A pipeline anti-clogging device according to the formula (publication number: CN 219604515U): includes a crushing box, the top and bottom ends of which are both equipped with conveying pipes, a crushing mechanism is installed inside the crushing box, a cleaning filter is installed inside the crushing box, and a filter cleaning mechanism is installed at one end inside the crushing box.

[0004] In the above application, due to the mutual cooperation between the conveying pipeline and the crushing mechanism components, it is difficult to solve the function of cleaning the outlet of the conveying pipeline during operation. As a result, after a period of cleaning, the conveying pipeline will be blocked when used again, and the accumulation of scale at the outlet cannot be reduced. Therefore, we proposed a pipeline anti-blocking device. Utility Model Content

[0005] The utility model aims to provide a pipeline anti-clogging device. Through the mutual cooperation between the electric telescopic rod, the air pressure chamber and the nitrogen chamber of the nitrogen cleaning mechanism, when the staff finds that the nozzle on the side of the reactor is blocked, nitrogen is first added to the nitrogen chamber through the filling hole of the nitrogen chamber, and then the electric telescopic rod is started so that the nitrogen is pushed by the extrusion plate to increase the pressure and flows into the hydrogen pipe through the nitrogen pipe. At this time, the gas inside the hydrogen pipe increases the flow rate, cleaning the nozzle. The staff can observe the flow rate and speed pressure of the nitrogen through the nitrogen flow meter and pressure gauge, and can adjust them to appropriate values ​​according to the hand valve.

At the same time as the triggering, the alarm light will flash, reminding the staff to repair the hydrogen pipeline. This design achieves the effect of detecting the leaking part and can promptly remind the staff to repair the hydrogen pipeline.
