Description

Technical Field

[0001] This utility model relates to the field of cleaning the inner surface of steel pipes, and in particular to a dust cleaning device for the inner surface of steel pipes. Background Technology

[0002] After production, processing, and storage, dust, iron filings, and other impurities easily accumulate on the inner surface of steel pipes. When using steel pipes, it is necessary to clean the inner surface of the steel pipes to remove the dust and impurities and prevent these impurities from affecting the subsequent processing and use of the steel pipes.

[0003] When cleaning the inner surface of a steel pipe, a brush is usually used. However, steel pipes are often quite long, and the brushes required for cleaning are also quite long, making the cleaning process cumbersome and inconvenient for removing dust from the inner surface of the steel pipe. Utility Model Content

[0004] In view of this, the present invention provides a dust cleaning device for the inner surface of steel pipes. The main technical problem to be solved is to simplify the dust cleaning process of the inner surface of steel pipes and to quickly clean the dust on the inner surface of steel pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dust cleaning device for the inner surface of a steel pipe, comprising a rotating plate, a support fixedly connected to the surface of the rotating plate, a steel pipe disposed on the upper surface of the rotating plate, one end of the steel pipe located inside the support, a movable groove opened at the left end of the rotating plate, a movable plate movably connected inside the movable groove, a pump fixedly connected to the surface of the movable plate, an air outlet pipe fixedly connected to the right end of the pump, a connecting pipe installed on the outer surface of the air outlet pipe, the end of the connecting pipe away from the air outlet pipe located inside the steel pipe, and a through hole opened on the surface of the connecting pipe.

[0006] By adopting the above technical solution, first adjust the angle of the rotating plate so that the rotating plate is tilted, then push the moving plate to the left to adjust the position of the connecting pipe, place the steel pipe on the rotating plate, support and limit one end of the steel pipe with the bracket, then release the moving plate to allow the connecting pipe to enter the interior of the steel pipe, start the pump to blow air into the connecting pipe, and discharge it through the through hole on the connecting pipe, so that the airflow acts on the inner surface of the steel pipe, thereby removing the dust on the inner surface of the steel pipe.

[0007] As a further description of the above technical solution:

[0008] The number of through holes is multiple, and the through holes are arranged at an angle.

[0009] By adopting the above technical solution, the inclined through hole can blow the airflow obliquely toward the inner surface of the steel pipe, which can increase the area of ​​the airflow acting on the inner surface of the steel pipe, making it easier to clean the dust from the inner surface of the steel pipe.

[0010] As a further description of the above technical solution:

[0011] The right end of the bracket is provided with a discharge groove, the position of which corresponds to the position of the inner cavity of the steel pipe.

[0012] By adopting the above technical solution, the dust on the inner surface of the steel pipe will be discharged from the discharge trough under the action of airflow and gravity.

[0013] As a further description of the above technical solution:

[0014] A connecting ring is fixedly connected to the outer surface of the air outlet pipe, and a connecting groove is formed on the inner surface of the connecting pipe, with the connecting ring located inside the connecting groove.

[0015] By adopting the above technical solution, it is easy to install the connecting pipe on the air outlet pipe, so that the connecting pipe can rotate on the air outlet pipe.

[0016] As a further description of the above technical solution:

[0017] A motor is fixedly connected to the outer surface of the movable plate, and a second gear is fixedly connected to the output shaft of the motor.

[0018] By adopting the above technical solution, the second gear can be driven to rotate by the operation of the motor.

[0019] As a further description of the above technical solution:

[0020] A first gear is fixedly connected to the outer surface of the connecting pipe, and the side of the first gear meshes with the side of the second gear.

[0021] By adopting the above technical solution, when the motor is working, it will drive the second gear to rotate, which in turn will drive the first gear to rotate, thereby driving the connecting pipe to rotate. This allows the airflow discharged from the through hole on the connecting pipe to fully contact the inner surface of the steel pipe, facilitating dust removal.

[0022] As a further description of the above technical solution:

[0023] The bottom of the rotating plate is provided with a base plate, and a support mechanism and a height adjustment mechanism are installed between the base plate and the rotating plate.

The column is installed on the base plate, the first rotating shaft is installed on the column, and the first connecting block is installed on the first rotating shaft. The first connecting block is fixedly connected to the rotating plate, and the rotating plate can rotate around the first rotating shaft. The height adjustment mechanism includes a cylinder, a second connecting block, a second rotating shaft, and a third connecting block. The cylinder is installed on the base plate, the second connecting block is installed on the top of the cylinder, the second rotating shaft is installed inside the second connecting block, and the third connecting block is installed at both ends of the second rotating shaft. The third connecting block is movably connected to the rotating plate. By operating the cylinder, the third connecting block can be moved up and down, thereby controlling the height of the left end of the rotating plate, so that the rotating plate can rotate around the first rotating shaft and adjust the tilt angle of the rotating plate to facilitate the discharge of dust inside the steel pipe.

[0025] By employing the above technical solution, the dust cleaning device for the inner surface of steel pipes of this utility model has at least the following beneficial effects:

[0026] 1. Compared with the prior art, this steel pipe inner surface dust cleaning device consists of a rotating plate, a support, a steel pipe, a moving plate, a pump, an air outlet pipe, a connecting pipe, and a through hole. In use, the angle of the rotating plate is first adjusted to make it tilted. Then, the moving plate is pushed to the left to adjust the position of the connecting pipe, placing the steel pipe on the rotating plate. The support supports and limits one end of the steel pipe. Afterward, the moving plate is released to allow the connecting pipe to enter the interior of the steel pipe. The pump is started, blowing air into the connecting pipe and discharging it through the through hole.

Then release the movable plate 6 to allow the connecting pipe 10 to enter the interior of the steel pipe 4. Start the pump 7 to blow air into the connecting pipe 10 and discharge it through the through hole 13 on the connecting pipe 10. Let the air flow act on the inner surface of the steel pipe 4 to remove the dust on the inner surface of the steel pipe. There are multiple through holes 13, and the through holes 13 are set at an angle. The angled through holes 13 can blow the air flow at an angle to the inner surface of the steel pipe 4, which can increase the area of ​​the air flow acting on the inner surface of the steel pipe 4, making it easier to clean the dust on the inner surface of the steel pipe 4.
