[0002] Large-diameter stainless steel pipes are a key component of domestic manufacturing and are widely used. After welding or pressing, stainless steel pipes form a scale on the surface. Thick scale requires pickling, but even after pickling, scale and acid remain inside the pipe. To ensure the surface quality of the stainless steel pipe's interior, it's necessary to rinse it with clean water to remove any residual scale and acid.

[0003] At present, the pickling and cleaning process of stainless steel pipe production in my country adopts the manual flushing method, which easily causes waste of water resources and human resources.

[0044] Please refer to Figure 8-11 The long telescopic sootblower device 3 includes a sootblower beam structure, which includes a sootblower lower crossbeam plate 307 and a sootblower upper crossbeam plate 309. The sootblower lower crossbeam plate 307 and the sootblower upper crossbeam plate 309 are connected by a plurality of crossbeam support frames 304 and a connecting support plate 321. A motor mounting frame 316 is provided below the sootblower upper crossbeam plate 309. A sootblower servo motor 311 is installed at one end of the motor mounting frame 316. A driving sprocket shaft 315 is provided on the output shaft of the servo motor 311, and a long chain driving transmission sprocket 314 is rotatably provided on the driving sprocket shaft 315.

A movable pulley 317 is provided above the movable pulley device 313. The movable pulley 317 is connected to the groove track of the motor mounting bracket 316. A long soft water pipe 318 is connected to the end of the barrel chain connecting device 312, and a long soft water pipe interface 308 is provided at the end of the long soft water pipe 318.

[0046] An interface is left at the lower end of the sootblower barrel 302, and a guide support pulley 323 component is installed through a thread; a threaded barrel port interface 301 is left at the end of the sootblower barrel 302.

[0047] The sootblower beam structure is supported by a number of support assemblies. Each support assembly includes a sootblower column 303 and a triangular support frame 310 . The triangular support frame 310 is fixed to the side of the sootblower column 303 .

[0048] Initially, the traverse hydraulic cylinder 101 and the jacking hydraulic cylinder 111 are in a closed state, the traverse base 106 is at the lowest end and the leftmost end, the rollers 212 are at a minimum spacing state, and the sootblower barrel 302 is at the origin position.

[0049] When in use, the lifting hydraulic cylinder 111 is turned on to drive the transverse base 106 to rise. When the transverse base 106 rises to the highest point of the stroke, the transverse hydraulic cylinder 101 is turned on to drive the transverse base 106 to move transversely. At this time, the steel pipe moves to the top of the steel pipe rotating device 2. The lifting hydraulic cylinder 111 is retracted and closed, and the steel pipe is separated from the transverse base 106 during the movement of the transverse base 106, and transitions to the steel pipe rotating device 2. Finally, the transverse hydraulic cylinder 101 is retracted and closed, and the steel pipe transverse device 1 is in the initial state; when the steel pipe transitions to the steel pipe rotating device 2, the screw motor 219 is started, and the two sets of screw slider platforms 218 move away from the two ends, and the distance between the rollers 212 is reasonably increased and adjusted to keep the height of the steel pipe axis at a fixed horizontal height, which is conducive to the soot blower gun barrel 302 entering the inner wall of the steel pipe for full coverage cleaning. After adjusting the distance between the rollers 212, the stepper motor 202 is started, and the rollers 212 are driven to rotate through the sprocket chain transmission relationship, thereby driving the steel pipe to rotate, which is conducive to increasing the effective contact area between the nozzle and the inner wall of the steel pipe and higher cleaning efficiency. At this time, start the soot blower servo motor 311 and open the pump valve to connect the long soft water pipe 318 to the water source, and use the sprocket chain transmission and support pulley moving module to drive the soot blower gun barrel 302 to extend into the inner wall of the steel pipe to achieve full coverage cleaning of the inner wall of the steel pipe by the nozzle. Example 1

[0050] Taking a single steel pipe as an example, the specific process of steel pipe lateral cleaning is as follows:

[0051] At the beginning, the transverse hydraulic cylinder 101 and the jacking hydraulic cylinder 111 are in the closed state, the stainless steel pipe is placed on the V-shaped frame of the transverse base 106, and is in the state of waiting for transverse movement. The jacking hydraulic cylinder 111 is pushed out first, the transverse base 106 rises first, the transverse hydraulic cylinder 101 is pushed out later, and the transverse base 106 moves transversely. At this time, the steel pipe is placed above the steel pipe rotating device 2, the jacking hydraulic cylinder 111 retracts part of the stroke, the steel pipe is transferred to the steel pipe rotating device 2, the jacking hydraulic cylinder 111 retracts all the stroke, and the long steel pipe 4 is completely connected with the steel pipe transverse device 1. Full separation, the transverse hydraulic cylinder 101 retracts the full stroke, at this time, the steel pipe transverse movement device 1 is in the initial state; the steel pipe is placed on the roller wheel on the steel pipe rotating device 2, and the screw motor 219 works to adjust the spacing of the roller wheels 212 according to the size of the steel pipe diameter, thereby ensuring that the steel pipe axis is always at the same horizontal height. Then, the stepper motor 202 works to drive the two sets of active sprockets 1 204 and active sprockets 210 to work. The active sprockets 1 204 and active sprockets 210 are in a state of rotation due to the sprocket chain. The mechanical matching relationship of the strips drives the driven sprocket 1 207 and the driven sprocket 2 208 to rotate, thereby driving the roller wheel 212 to rotate, and then driving the long steel pipe 4 to support the self-rotation function; at this time, the long steel pipe 4 is self-rotating on the steel pipe rotating device 2, and the soot blower servo motor 311 starts to work and drives the long chain active transmission sprocket 314 to rotate, thereby driving the long chain 306 to rotate; the long chain 306 is fixedly connected to the barrel chain connecting device 312, and the barrel chain connecting device 312 is fixedly connected to the soot blower barrel 302 The long chain 306 rotates to drive the soot blower barrel 302 fixedly connected to it to move forward and extend, and the barrel port interface 301 has an internal thread interface connected to the self-rotating nozzle, so as to achieve full coverage cleaning of the dirt on the inner wall of the steel pipe by the soot blower. When the barrel port interface 301 moves to the end of the steel pipe, the soot blower completes the cleaning of the inner wall of the steel pipe. Then, the soot blower servo motor 311 rotates in the opposite direction, the water valve of the water pipe is closed, and the soot blower barrel 302 returns to the initial position, waiting for the next steel pipe to move horizontally to the steel pipe rotating device 2.
