[0030] In operation, as the external protective structure of the entire device, it supports and contains other components, its solid shell can protect the internal drive assembly 2 and air inlet assembly 3 from external environment such as collision, dust, etc., at the same time, the shell 101 also provides a stable foundation for the installation of each component, ensuring that the device will not damage the internal structure due to vibration or external force during operation, the handle 102: facilitates the operator to carry and move the entire dust removal device, during use, the operator can easily carry the device to the vicinity of the boiler that needs to be dusted by holding the handle 102, and place it accurately in the appropriate position, for example, when the boiler in different positions needs to be dusted, the handle 102 makes the movement of the device more convenient and efficient, the U-shaped connecting rod 201: fixed inside the shell 101, provides stable support for the servo motor 202, rotating pipe 204 and rotating sleeve 205, the shape design of the U-shaped connecting rod 201 makes the installation of each component more compact, and also ensures their relative position stable during operation, for example, when the servo motor 202 is running, the U-shaped connecting rod 201 can effectively prevent the vibration of the motor from being transmitted to other components, thereby improving the stability of the entire device, the servo motor 202: as the power source of the drive assembly 2, its output end connected to the driving bevel gear 203 rotates under the drive of the motor, the servo motor 202 has precise speed control and powerful torque output capability, which can adjust the speed of the rotating pipe 204 and the rotating sleeve 205 according to actual needs to achieve the best dust removal effect, for example, in different boiler dusting scenarios, the speed of the servo motor 202 can be controlled to adapt to different dust accumulation conditions and boiler structures, the driving bevel gear 203: meshing connection with the first driven bevel gear 206 and the second driven bevel gear 207, transmits power from the servo motor 202 to the rotating pipe 204 and the rotating sleeve 205, due to the high transmission efficiency and stability of the meshing transmission of bevel gears, it can ensure the effective transmission of power, at the same time, by changing the gear ratio of bevel gears, the speed ratio of the rotating pipe 204 and the rotating sleeve 205 can be adjusted to meet different working requirements, for example, when the rotating pipe 204 needs to blow air at a high speed, the gear ratio of bevel gears can be adjusted to make the rotating pipe 204 rotate relatively fast, while the rotating sleeve 205 rotates relatively slow, to ensure that the scraper rod 208 can effectively remove the blockage on the surface of the rotating pipe 204, the rotating pipe 204: rotates under the drive of the driving bevel gear 203 and the first driven bevel gear 206, the middle part of the rotating pipe 204 is provided with a plurality of air outlets, when the air compressor 301 sends compressed air into the rotating pipe 204 through the connecting pipe 302 and the rotary joint 303, the air is blown out from the air outlets, as the rotating pipe 204 changes the direction of air blowing during rotation, it can blow off the dust in each position of the boiler, for example, when dusting the boiler, the rotating pipe 204 is inserted into the feed inlet at the upper end of the boiler,With the rotation of the rotating pipe 204, compressed air can be uniformly blown to every corner of the inside of the boiler, effectively blowing up the dust, facilitating subsequent collection and processing. The rotating sleeve 205 rotates under the drive of the driving cone gear 203 and the second driven cone gear 207, and its rotation direction is opposite to that of the rotating pipe 204. The scraping rod 208 fixedly connected to the lower end of the rotating sleeve 205 rotates with the rotation of the sleeve, which can scrape the holes on the surface of the rotating pipe 204 to prevent dust from blocking the air outlet during cleaning. For example, when the rotating pipe 204 is in the process of blowing air, some dust particles may block the air outlet. At this time, the scraping rod 208 can timely remove the blockage to ensure the normal blowing function of the rotating pipe 204. The air blowing pump 301, as the core component of the air inlet assembly 3, compresses external air and sends it into the rotating pipe 204 through the connecting pipe 302. The air blowing pump 301 can provide sufficient air pressure and flow to ensure that compressed air can be blown out of the air outlet of the rotating pipe 204 at high speed to blow off the dust inside the boiler. For example, in the dust removal process of a large boiler, the air blowing pump 301 needs to have high power and performance to meet the cleaning needs of a large amount of dust. The connecting pipe 302 connects the air blowing pump 301 and the rotating pipe 204, and transports compressed air from the air blowing pump 301 to the rotating pipe 204. The connecting pipe 302 is usually made of pressure-resistant and corrosion-resistant materials to ensure that it will not leak or be damaged during the transportation of compressed air. For example, in some harsh working environments, the connecting pipe 302 needs to be able to withstand high temperature, high pressure and corrosive gas to ensure the normal operation of the device. The rotary joint 303 is installed between one end of the connecting pipe 302 and the upper end of the rotating pipe 204, so that the rotating pipe 204 can be in good sealed connection with the connecting pipe 302 during rotation, while not affecting the transportation of air. The rotary joint 303 usually has a special sealing structure and bearing design inside to enable the rotating pipe 204 to rotate freely while bearing a certain pressure. For example, when the rotating pipe 204 rotates at a high speed, the rotary joint 303 can ensure that there is no air leakage between the connecting pipe 302 and the rotating pipe 204, ensuring stable transportation of compressed air.

[0031] When the boiler dust removal operation is performed, the operator first carries the whole device to the vicinity of the boiler through the handle 102, and inserts the rotating pipe 204 into the feeding port at the upper end of the boiler. Then the air blowing pump 301 and the servo motor 202 are started, the air blowing pump 301 sends compressed air into the rotating pipe 204 through the connecting pipe 302 and the rotary joint 303, the air is sprayed from the air outlet of the rotating pipe 204, and the dust inside the boiler is blown off. At the same time, the servo motor 202 drives the rotating pipe 204 and the rotating sleeve 205 to rotate through the driving cone 203, the first driven cone 206 and the second driven cone 207 respectively, the rotating pipe 204 changes the air blowing direction during rotation, and the dust at various positions in the boiler is cleaned. The scraping rod 208 at the lower end of the rotating sleeve 205 scrapes the holes on the surface of the rotating pipe 204 with the rotation of the sleeve, preventing blockage. The whole device solves the problem that the existing boiler sealing arrangement is difficult to clean the internal dust through the cooperative work of various components, is convenient and fast to use, and does not need too much operation.
