Description

Technical Field

[0001] This utility model relates to the field of internal blowing technology for circular tubes, and in particular to an internal blowing device for circular tubes. Background Technology

[0002] A round tube is a steel tube that is open at both ends and has a hollow concentric circular cross-section, with a length that is relatively large compared to its perimeter. It can be used for pipelines, thermal equipment, machinery industry, oil and gas drilling, containers, chemical industry, and other special applications. The specifications of round tubes are expressed by their external dimensions (such as outer diameter or side length), inner diameter, and wall thickness. Their size range is very wide, from very small capillary tubes to large round steel pipes with diameters of several meters.

[0003] A circular tube internal blowing device is an engineering device that achieves specific functions by injecting a controlled airflow (such as compressed air, steam, inert gas, etc.) into the interior of a circular tube. Its core is based on the principles of airflow dynamics, combined with nozzles, an air supply system, and a control unit, to perform operations inside the pipe, such as removing residual dust, debris, or liquid.

[0004] When using an air blowing device to clean the inner wall of a pipe, the pipe is usually placed using two sets of support rollers, and then air is blown through the air outlet. However, the positions of the two sets of support rollers are usually fixed, which makes it impossible to adjust their positions. This makes it impossible to use pipes of different diameters. At the same time, the position of the existing air outlet is also fixed, which makes it impossible to use pipes of different diameters. Utility Model Content

A support plate 16 is installed on one side of the workbench 1 through a second adjustment mechanism. The second adjustment mechanism includes a third motor 13 fixedly installed on one side of the workbench 1. A bidirectional threaded rod 14 is fixedly installed at the output end of the third motor 13. A third moving block 15 is threaded on the surface of the bidirectional threaded rod 14.

[0019] Specifically, the top of the workbench 1 is provided with a first slide groove 21 and a third slide groove 23, and one side of the mounting block 5 is provided with a second slide groove 22. The inner wall of the first slide groove 21 is in contact with the surface of the first moving block 4, limiting the movement of the first moving block 4 and making its movement more stable.

[0021] In use: When using this round tube internal blowing device, the round tube is placed between the two sets of support rollers 17. The electric push rod 19 drives the pressure plate 20 to descend, thus fixing the round tube with the pressure plate 20 and support rollers 17. By starting the air pump 10, the air pump 10 outputs gas into the air delivery pipe 11, and finally sprays it out through the air outlet 12. At the same time, the first motor 2 drives the first lead screw 3 to rotate, the first lead screw 3 drives the first moving block 4 to move, the first moving block 4 drives the mounting block 5 to move, and the mounting block 5 drives the air outlet 12 to move, thus blowing air through the air outlet 12 to clean the inner wall of the round tube. After cleaning, the first motor 2 drives the air outlet 12 to reset, and at the same time, the electric push rod 19... The pressure plate 20 is used to loosen the fixing of the round tube, allowing the round tube to be removed. The third motor 13 drives the bidirectional threaded rod 14 to rotate, which in turn drives the two sets of third moving blocks 15 to move in opposite directions. The third moving blocks 15 drive the two sets of support plates 16 to move in opposite directions, and the support plates 16 drive the two sets of support rollers 17 to move in opposite directions. This allows for the placement of round tubes of different diameters. The second motor 6 drives the second lead screw 7 to rotate, which in turn drives the second moving block 8 to rise and fall. The second moving block 8 drives the mounting plate 9 to rise and fall, and the mounting plate 9 drives the air outlet 12 to rise and fall. This allows the air outlet 12 to be aligned with the center of the round tube, achieving the purpose of conveniently blowing air onto round tubes of different diameters. The structure is simple and easy to use.
