Description

Technical Field

[0001] This utility model relates to the technical field of pipeline cleaning devices, and in particular to a long-distance pipeline cleaning device for external pipe corridors. Background Technology

[0002] In coal chemical, natural gas chemical, and petrochemical industries, welding slag is present during pipeline welding, and other foreign objects may be present in the pipeline during construction. Therefore, various methods must be used to remove debris. For air purging and blasting purging of long-distance pipelines, the pressure inside the pipeline is relatively high, and the safety requirements for operators are high during the purging process, which also consumes a large amount of compressed air. Manual cleaning of long-distance pipelines is usually limited by limited tools, high manpower consumption, and high safety requirements. Therefore, we propose a long-distance pipeline cleaning device for external pipe racks. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to propose a long-distance pipe cleaning device for external pipe corridors, which greatly improves cleaning capabilities and reduces labor costs.

[0004] The long-distance pipe cleaning device for external pipe corridors proposed in this utility model includes a launching pipe, a receiving pipe, and a pipe to be cleaned. An air inlet pipe is embedded in the side wall of the launching pipe, and a first ball valve is installed inside the launching pipe. A first connecting flange is fixedly connected to one end of the launching pipe near the pipe to be cleaned, and a ball passage is provided on the inner wall of the launching pipe. An air outlet pipe is embedded in the side wall of the receiving pipe, and a second connecting flange is fixedly connected to one end of the receiving pipe near the pipe to be cleaned. Both the second connecting flange and the first connecting flange are connected to the pipe to be cleaned. A support plate is fixedly connected to the bottom of the receiving pipe, and a ball-collecting net is fixedly connected to the side wall of the support plate.

[0005] Preferably, the first ball valve extends through the launching tube to the top, and a pressure gauge is provided at the top of the air inlet pipe near the first ball valve.

[0006] Preferably, both the launching tube and the receiving tube are fixedly connected to blind flanges in opposite directions.

[0007] Preferably, a second ball valve is provided inside the wall of the air outlet pipe.

[0008] Preferably, a GPS positioning component is embedded inside the ball.

[0009] The beneficial effects of this utility model are: by automatically pushing the ball with compressed air, the workload is greatly reduced and there is no other loss. The air consumption is greatly reduced, and the pipe to be cleaned can be cleaned separately by the ball and the sponge ball, which greatly improves the cleaning ability and reduces labor costs.

[0015] Reference Figure 1-4The long-distance pipeline cleaning device for external pipe corridors includes a launching pipe 1, a receiving pipe 2, and a pipe 4 to be cleaned. An air inlet pipe 1 is embedded in the side wall of the launching pipe 1, and a first ball valve 12 is installed inside the launching pipe 1. A first connecting flange 14 is fixedly connected to one end of the launching pipe 1 near the pipe 4 to be cleaned, and a ball passage 5 is installed on the inner wall of the launching pipe 1. An air outlet pipe 21 is embedded in the side wall of the receiving pipe 2, and a second connecting flange 23 is fixedly connected to one end of the receiving pipe 2 near the pipe 4 to be cleaned. Both the second connecting flange 23 and the first connecting flange 14 are connected to the pipe 4 to be cleaned. A support plate 3 is fixedly connected to the bottom of the receiving pipe 2, and a ball-collecting net 31 is fixedly connected to the side wall of the support plate 3. Furthermore, the first ball valve 12 extends through the launching pipe 1 to its top, and a pressure gauge 13 is installed at the top of the air inlet pipe 11 near the first ball valve 12. The pressure value inside the pipe 4 to be cleaned can be observed by looking at the pressure gauge 13. Furthermore, both the launching tube 1 and the receiving tube 2 are fixedly connected to blind flanges 15 in opposite directions, which can seal the launching tube 1 and the receiving tube 2. Furthermore, a second ball valve 22 is installed inside the wall of the air outlet pipe 21, which can adjust the air output of the air outlet pipe 21. Furthermore, a GPS positioning component 51 is embedded inside the ball 5 to facilitate tracking the position of the ball 5 within the pipe 4 to be cleaned.

[0016] When using this device, firstly, the ball 5 is placed inside the launching tube 1, and then the launching tube 1 and the pipe 4 to be cleaned are connected through the first connecting flange 14. Then, the air inlet pipe 11 supplies air to the inside of the launching tube 1. When the inside is full of air pressure, it will push the ball 5 to move. The internal air pressure can be adjusted by opening the first ball valve 12, which is conducive to the slow and stable air pressure inside the pipe 4 to be cleaned. Then, during the movement of the ball 5, the GPS positioning component 51 is used to track the position of the ball 5 in the pipe 4 to be cleaned. When the ball 5 is about to move into the receiving tube 2, the blind flange 15 on one side of the receiving tube 2 is opened. Finally, the ball 5 will move and fall into the receiving net 31. Then, the second ball valve 22 is opened to exhaust air through the air outlet pipe 21. After the ball 5 can clean up debris and debris, the ball 5 can be replaced with a sponge ball to further clean the pipe 4 to be cleaned, which greatly improves the cleaning ability.
