Description

Technical Field

[0001] The utility model relates to the technical field of cleaning furnace tubes and flues or chimneys, in particular to a shock wave sootblower for a boiler. Background Art

[0002] The shock wave soot blower, also known as the gas pulse soot blower, is a device that uses gas pulse technology for cleaning. It is widely used in boiler ash removal systems. It is similar to the pulse soot blower, but the gas pulse soot blower focuses more on using gas as a power source, while the pulse soot blower may use acetylene or other combustible gases. Therefore, there are differences in the application scenarios and cleaning effects of the two. When using a shock wave soot blower to clean the boiler, the soot blower is fixedly connected to the outer surface of the boiler, and then the soot blowing pipe extends into the interior of the boiler. The shock wave generated then enters the interior of the boiler through the soot blowing pipe for cleaning.

[0003] At present, in order to increase the cleaning range of the soot blower, the soot blowing pipe is usually connected to the soot blower body through rotation, and then the soot blowing pipe is driven to rotate by a motor, and then the soot blowing pipe outlet extending into the boiler will change direction, thereby increasing the cleaning range. However, because the soot blowing pipe and the soot blower body are rotationally connected, during use, the force generated by the shock wave will push the soot blowing pipe to the side away from the soot blower, and then a gap will appear in the rotational connection between the two, and then the sealing structure will be damaged, which will weaken the impact force ejected through the soot blowing pipe, thereby reducing the cleaning quality of the shock wave soot blower. In order to improve the quality, it is necessary to increase the impact force, and to increase the impact force, it is necessary to increase the use of gas, thereby increasing the energy consumption of the device.

The rotating mechanism includes a limit tooth groove 10, a limit gear 11, a transmission groove 12, a transmission gear 13, a speed reduction motor assembly 14, a first intake pipe 16 and a second intake pipe 17.

[0032] Further, the limit tooth groove 10 is formed inside the fixed block 5, the limit gear 11 is arranged inside the limit tooth groove 10, the left and right sides of the limit gear 11 are respectively rotationally connected to the left and right walls of the limit tooth groove 10, the right side of the limit gear 11 is fixedly connected to the left side of the soot blower body 6, the transmission groove 12 is formed inside the fixed block 5, the transmission groove 12 is arranged on the front side of the limit tooth groove 10, the transmission groove 12 communicates with the inside of the limit tooth groove 10, the transmission gear 13 is arranged inside the transmission groove 12, the left and right sides of the transmission gear 13 are respectively rotationally connected to the left and right walls of the transmission groove 12, the transmission gear 13 is meshed with the limit gear 11, the speed reduction motor assembly 14 is fixedly connected to the left side of the fixed block 5, the output end of the speed reduction motor assembly 14 is fixedly connected with a transmission shaft 15, the right end of the transmission shaft 15 rotates and extends into the inside of the soot blower body 6, the right end of the transmission shaft 15 rotates and extends into the inside of the transmission groove 12, the right end of the transmission shaft 15 is fixedly connected to the left side of the transmission gear 13, the first air inlet pipe 16 is arranged on the left side of the fixed block 5, the right end of the first air inlet pipe 16 extends into the inside of the fixed block 5, the right end of the first air inlet pipe 16 extends past the limit gear 11, the right end of the first air inlet pipe 16 is fixedly connected to the left side of the soot blower body 6, the inside of the first air inlet pipe 16 communicates with the inside of the soot blower body 6, the second air inlet pipe 17 is rotationally connected to the left end of the first air inlet pipe 16, and the rotational connection between the second air inlet pipe 17 and the first air inlet pipe 16 is an existing connection structure, so no more explanation is given.

[0033] Furthermore, when it is necessary to clean the interior of the boiler 1, the staff will first disassemble the pipes, covers and the like connected to the flange 4, and then align the sootblower body 6 and the sootblowing pipe 7 with the connecting pipe 3 and extend them into the interior of the boiler 1, so that the fixing block 5 will contact the flange 4, and then rotate the fixing block 5 to align the threaded holes on the flange 4 and the fixing block 5, and then connect the flange 4 and the fixing block 5 through the bolts 8 and the nuts 9, and then send gas into the interior of the sootblower body 6 through the second air inlet pipe 17 and the first air inlet pipe 16, and then ignite the gas to generate a shock wave, and then the shock wave is transmitted through the sootblowing pipe 7, and then it will impact the internal dust of the boiler 1, so that the dust on the inner wall of the boiler 1 falls off, and at the same time start the retarder motor assembly 14, and then the retarder motor assembly 14 starts to transmit power from the output end, driving the transmission shaft 15 to rotate, and the transmission shaft 15 drives the transmission gear 13 to rotate synchronously, The transmission gear 13 drives the meshing limit gear 11 to rotate, and the limit gear 11 drives the soot blower body 6 to rotate synchronously, and the soot blower body 6 drives the soot blowing pipe 7 to rotate synchronously, and then the nozzle direction of the soot blowing pipe 7 will change, thereby increasing the soot cleaning range.

At the same time, when the soot blower body 6 rotates, it will drive the first air intake pipe 16 to rotate synchronously. However, because the second air intake pipe 17 is rotatably connected to the first air intake pipe 16, the rotation of the soot blower body 6 will not affect the efficiency of the first air intake pipe 16 and the second air intake pipe 17 to transport gas to the inside of the soot blower body 6. In this way, the function of the soot cleaning range of the device can be increased without the soot blowing pipe 7 being rotatably connected to the soot blower body 6, thereby making the connection between the soot blowing pipe 7 and the soot blower body 6 a fixed connection, thereby avoiding unnecessary loss of resources.

[0034] Working principle: When it is necessary to clean the ash inside the boiler 1, the staff first remove the pipes, covers, etc. connected to the flange 4. Then, the soot blower body 6 and the soot blowing pipe 7 are aligned with the connecting pipe 3 and extended into the boiler 1. Then, the fixing block 5 will contact the flange 4. Then, rotate the fixing block 5 to align the threaded holes on the flange 4 and the fixing block 5. Then, connect the flange 4 and the fixing block 5 through the bolt 8 and the nut 9. Then, send gas into the soot blower body 6 through the second intake pipe 17 and the first intake pipe 16. Then, ignite the gas to generate a shock wave. Then, the shock wave is transmitted through the soot blowing pipe 7. Then, it will impact the dust inside the boiler 1. Then, the dust on the inner wall of the boiler 1 will fall off. At the same time, start the speed reduction motor assembly 14. Then, the speed reduction motor assembly 14 starts to transmit power from the output end, drives the transmission shaft 15 to rotate. The transmission shaft 15 drives the transmission gear 13 to rotate synchronously. The transmission gear 13 drives the engaged limit gear 11 to rotate. The limit gear 11 drives the soot blower body 6 to rotate synchronously. The soot blower body 6 drives the soot blowing pipe 7 to rotate synchronously. Then, the orientation of the nozzle of the soot blowing pipe 7 will change. Then, the ash cleaning range can be increased. At this time, the fixed connection between the soot blower body 6 and the soot blowing pipe 7 avoids the waste of impact force. At the same time, when the soot blower body 6 rotates, it will drive the first intake pipe 16 to rotate synchronously. However, because the second intake pipe 17 and the first intake pipe 16 are rotatably connected, the rotation of the soot blower body 6 will not affect the efficiency of the first intake pipe 16 and the second intake pipe 17 in delivering gas to the inside of the soot blower body 6.
