[0017] S1: First, connect the limit tubes at both ends of the main body to the air inlet device and the air outlet device respectively, then start the motor and the air pump. The motor will drive the threaded rod to rotate when working;

[0018] S2: When the threaded rod rotates, it drives the placement slot to move downward, and when the placement slot moves downward, it drives the fixing ring to move downward, and when the fixing ring moves downward, the auxiliary mechanism moves the surface of the heating tube;

[0019] S3: The dust on the heating tube will be cleaned off during the movement, and the cleaned dust will fall into the collection box at the bottom of the main body, completing the cleaning work.

[0020] The present invention has the following beneficial effects:

[0021] 1. In the present invention, when the motor moves downward, the air pump is started. When the air pump is working, high-pressure gas is generated and enters into a plurality of fixed rings through connecting pipes. When the high-pressure gas enters the interior of the fixed ring, the gas impacts the grille ring. After the grille ring is impacted by the high-pressure gas, it drives the toothed disc to rotate through the curved pipe. At the same time, when the gas impacts the grille ring, the gas also enters the curved pipe and is ejected through the air outlet pipe on the side wall of the curved pipe. At this time, when the gas is ejected through the curved pipe, the gas is ejected toward the surface of the heating pipe in a spiral motion under the rotation of the curved pipe. At the same time, when the curved pipe ejects gas, the reverse impact force generated by the gas ejection causes the curved pipe to rotate at the bottom of the grille ring. When the curved pipe rotates, the angle at which the curved pipe is ejected can be changed, thereby increasing the ejection area of ​​the gas ejected onto the heating pipe. At the same time, when the gas is ejected through the curved pipe, part The high-pressure airflow ejected separately will spray onto the surface of the square plate on the top of the gear ring. When the square plate is impacted, it will rotate inside the hollow ring. When the gear ring rotates, it will drive multiple gear shafts to rotate. When the gear shaft rotates, the plug rod on its surface will slide inside the two-way threaded sleeve. When the plug rod slides, it will drive the hollow ring to move up and down through the gear shaft. When the gear ring rotates, the rotation of the gear ring will drive one end of the rubber shaft to rotate through friction. When the rubber shaft rotates, it will produce a twisting and shortening deformation. When the rubber shaft becomes shorter, it will pull the hollow ring 2 downward, and when the hollow ring 2 moves downward, it will slide on the surface of the heating tube. At this time, the sliding hollow ring 2 will push and peel off the stubborn dust on the heating tube. At the same time, when the curved tube rotates and ejects gas, the ejected gas has a stronger tangential force on the surface of the heating tube, which can better clean the stubborn dust and avoid the accumulation of dust adhering to the surface of the heating tube for a long time and affecting the heating performance.

[0022] 2. In the present invention, when the rubber shaft pulls the hollow ring 2 downward, the downward movement of the hollow ring 2 will drive the connecting plate to move downward. When the connecting plate moves downward, it will pull the L rod to slide backward in the rectangular groove at the bottom of the hollow ring 2. When the L rod slides backward, the L rod will drive the middle plate to rotate backward through the connecting frame. When the middle plate rotates backward, the middle plate squeezes the two ends of the arc plate. When the two ends of the arc plate are squeezed, the middle part of the arc plate will bulge outward. When the arc plate is deformed, it will press the rubber shaft to make it fit on the surface of the heating tube. Then, when the gear ring rotates through When the front end of the rubber shaft is driven to rotate by friction, since the rear end of the rubber shaft is fixed, the front end of the rubber shaft will form a spiral deformation when rotating. When the rubber shaft is deformed, it can play a buffering role on the surface of the heating tube, avoiding the hard contact of the hollow ring 2 with the surface of the heating tube when scraping dust, thereby greatly reducing the damage to the surface of the heating tube. At the same time, the spiral deformation of the rubber shaft can make the hollow ring 2 more evenly stressed when scraping dust, avoiding damage to the heating tube caused by excessive local pressure, improving the cleaning effect, and ensuring that the dust is completely removed.

[0023] 3. In the present invention, when the connecting rod drives the toothed disc to rotate, the rotation of the toothed disc will drive the gear to rotate, and the rotation of the gear will drive the auger to rotate. At the same time, when the high-pressure gas enters the interior of the fixed ring, part of the high-pressure gas inside the fixed ring will enter the spiral sleeve through the air intake frame. At this time, when the auger rotates, the rotation of the auger will drive the inclined plate to rotate synchronously. After that, when the high-pressure gas enters the interior of the spiral sleeve through the air intake frame, it will flow downward in a spiral motion inside the spiral sleeve along the spiral groove inside the spiral sleeve and the rotation of the auger. When the gas flows downward, the flow of the gas will form a pressure difference at the spiral groove opened on the surface of the spiral sleeve. At this time, the pressure difference is formed. The square grooves on the surface of the spiral sleeve will adsorb the dust cleaned from the outside. At the same time, when the auger drives the inclined plate to rotate, the rotation of the inclined plate will also generate adsorption force at the square groove. Combined with the downward flow of high-pressure airflow, the dust cleaned from the outside will be adsorbed into the spiral sleeve and the downward flow of high-pressure airflow will drive the cleaned dust to be discharged downward, reducing the dust flying when the spiral barrel is cleaning the dust, and reducing the dust flying on the heating tube caused by the high-pressure gas ejected from the curved tube when cleaning the heating tube. While reducing the dust residue in the surrounding environment, it also reduces the risk of secondary pollution, thereby improving the overall cleaning effect and the heat exchange efficiency of the heating tube.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] A method for using an electric heater dust removal device, the electric heater dust removal device, the method comprising the following steps:

[0053] S1: First, the limiting tubes 101 at both ends of the main body 1 are connected to the air inlet device and the air outlet device respectively, and then the motor 201 and the air pump 104 are started. When the motor 201 is working, it will drive the threaded rod to rotate;

[0054] S2: When the threaded rod rotates, it drives the placement groove 204 to move downward, and when the placement groove 204 moves downward, it drives the fixing ring 301 to move downward, and when the fixing ring 301 moves downward, the auxiliary mechanism 5 moves the surface of the heating tube 103;

[0055] S3: During the movement, the dust on the heating tube 103 will be cleaned off, and the cleaned dust will fall into the collection frame at the bottom of the main body 1, thus completing the cleaning work.

[0056] When in use, first connect the limit tubes 101 at both ends of the main body 1 to the air intake device and the air outlet device respectively, then start the motor 201 and the air pump 104, the motor 201 will drive the threaded rod to rotate when working, and the threaded rod will drive the placement groove 204 to move downward when rotating, and the placement groove 204 will drive the fixing ring 301 to move downward when moving downward, and the fixing ring 301 will make the auxiliary mechanism 5 move the surface of the heating tube 103 when moving, and the dust on the heating tube 103 will be cleaned off during the movement, and the cleaned dust will fall into the collection frame at the bottom of the main body 1, completing the cleaning work.

[0057] When the motor 201 works to move the lifting plate 203 downward, the air pump 104 is started. When the air pump 104 works, it generates high-pressure gas and enters into the multiple fixed rings 301 through the connecting pipes. When the high-pressure gas enters the interior of the fixed ring 301, the gas will impact the grille ring 302. After the grille ring 302 is impacted by the high-pressure gas, it will drive the toothed disc 305 to rotate through the curved tube 303. At the same time, when the gas impacts the grille ring 302, the gas will also enter the curved tube 303 and pass through the curved tube 303. The gas is ejected through the outlet pipe on the side wall. At this time, when the gas is ejected through the curved pipe 303, the gas will be ejected toward the surface of the heating pipe 103 in a spiral motion under the rotation of the curved pipe 303. At the same time, when the gas is ejected from the curved pipe 303, the reverse impact force generated by the gas during the ejection will cause the curved pipe 303 to rotate at the bottom of the grille ring 302. When the curved pipe 303 rotates, the angle at which the curved pipe 303 is ejected can be changed, thereby increasing the ejection area of ​​the gas ejected onto the heating pipe 103.

When the plug rods slide, the hollow ring 403 will be driven to move up and down through the gear shafts 402. When the gear ring 404 rotates, the rotation of the gear ring 404 will drive one end of the rubber shaft 603 to rotate through friction, and the rubber shaft When 603 rotates, it will produce a twisting and shortening deformation.

At this time, the sliding hollow ring 2 503 will push and peel off the stubborn dust on the heating tube 103. At the same time, when the curved tube 303 rotates and sprays gas, the sprayed gas has a stronger tangential force on the surface of the heating tube 103, which can better clean the stubborn dust and avoid dust accumulation adhering to the surface of the heating tube for a long time and affecting the heating performance.

[0058] When the rubber shaft 603 pulls the hollow ring 2 503 to move downward, the downward movement of the hollow ring 2 503 will drive the connecting plate 502 to move downward. When the connecting plate 502 moves downward, it will pull the L rod 504 to slide backward in the rectangular groove at the bottom of the hollow ring 2 503. When the L rod 504 slides backward, the L rod 504 will drive the middle plate 601 to rotate backward through the connecting frame 505. When the middle plate 601 rotates backward, the middle plate 601 squeezes the two ends of the arc plate 602. When the two ends of the arc plate 602 are squeezed, the middle part of the arc plate 602 will produce an outward bulging deformation. When the arc plate 602 is deformed, it will press the rubber shaft 603 to make it fit the heating tube 103. Surface, and then when the rotation of the gear ring 404 drives the front end of the rubber shaft 603 to rotate through friction, since the rear end of the rubber shaft 603 is fixed, the front end of the rubber shaft 603 will form a spiral deformation when rotating. When the rubber shaft 603 is deformed, it can play a buffering role on the surface of the heating tube 103, avoiding the hard contact of the hollow ring 2 503 with the surface of the heating tube when scraping dust, thereby greatly reducing the damage to the surface of the heating tube. At the same time, the spiral deformation of the rubber shaft 603 can make the hollow ring 2 503 more evenly stressed when scraping dust, avoiding damage to the heating tube caused by excessive local pressure, improving the cleaning effect, and ensuring that the dust is completely removed.

[0059] When the connecting rod 304 drives the toothed disc 305 to rotate, the rotation of the toothed disc 305 will drive the gear 705 to rotate, and the rotation of the gear 705 will drive the auger 703 to rotate. At the same time, when the high-pressure gas enters the interior of the fixed ring 301, part of the high-pressure gas inside the fixed ring 301 will enter the spiral sleeve 702 through the air intake frame 701. At this time, when the auger 703 rotates, the rotation of the auger 703 will drive the inclined plate 704 to rotate synchronously. Afterwards, when the high-pressure gas enters the interior of the spiral sleeve 702 through the air intake frame 701, it will flow downward in a spiral motion inside the spiral sleeve 702 along the spiral groove inside the spiral sleeve 702 and the rotation of the auger 703. When the gas flows downward, the flow of the gas will be in the spiral groove opened on the surface of the spiral sleeve 702 A pressure difference is formed at the spiral sleeve 702, and the formation of the pressure difference at this time will adsorb the dust cleaned from the outside through the square grooves on the surface of the spiral sleeve 702. At the same time, when the auger 703 drives the inclined plate 704 to rotate, the rotation of the inclined plate 704 will also generate an adsorption force at the square grooves. Combined with the downward flow of the high-pressure airflow, the dust cleaned from the outside is adsorbed into the spiral sleeve 702, and the downward flow of the high-pressure airflow drives the cleaned dust to be discharged downward, thereby reducing the dust flying when the spiral cylinder is cleaning the dust, and reducing the dust flying on the heating tube 103 caused by the high-pressure gas ejected from the curved tube 303 when cleaning the heating tube 103. While reducing the dust residue in the surrounding environment, the risk of secondary pollution is reduced, thereby improving the overall cleaning effect and the heat exchange efficiency of the heating tube 103.
