Description

Technical Field

[0001] The present invention relates to the technical field of anti-corrosion coating spraying, in particular to a device for spraying anti-corrosion coating on the inner wall of a waste incinerator tube row. Background Art

[0002] Waste incineration, as a mainstream method for municipal waste disposal, not only achieves waste reduction, harmlessness, and resource utilization, but also faces numerous equipment maintenance challenges. During operation, waste incinerators present extremely harsh environmental conditions. Furnace temperatures typically range from 800-1200°C, generating large quantities of corrosive gases such as HCl, SO₂, and Cl₂, as well as fly ash particles. The pipe banks, key components of waste incinerators, are exposed to this harsh environment for long periods of time, subjecting their interior walls to severe oxidative and chemical corrosion. This results in a service life of only one to two years for standard metal pipe banks. Frequent pipe bank replacement not only requires significant manpower, material, and financial resources, increasing the incinerator's operational and maintenance costs, but also impacts the incinerator's uptime and reduces waste treatment efficiency. To address this corrosion problem, spraying anti-corrosion coatings on the pipe bank interior has become an effective protective measure.

[0003] During the use of the device, metal particles and dust particles may remain in some areas of the inner wall of the pipe. After spraying, valleys will be formed between the paint and the pipe, affecting the adhesion between the spray paint and the inner wall of the pipe.

[0014] The present invention has the following beneficial effects: (1) The present invention addresses the problem that the area of ​​residual metal particles and dust particles in the pipeline will affect the adhesion between the spray coating and the inner wall of the pipeline, forming a valley. After the device is placed in the pipeline and installed, the motor is started, the motor drives the rotating shaft to rotate, and the rotating shaft drives the fixed block 2 to rotate. When the fixed block 2 rotates, the slider 2 slides outward under the action of centrifugal force to scrape off the welding slag and dust particles remaining on the inner wall of the pipeline. Because the scraper and the fixed block 1 are tilted at a certain angle, after scraping the inner wall, it will rotate and push the scraped welding slag and dust particles to move forward with the device until they are pushed out of the pipeline, so that the inner wall of the pipeline can be cleaned before spraying, avoiding the area of ​​residual metal particles and dust particles in the pipeline that will affect the adhesion between the spray coating and the inner wall of the pipeline, forming a valley, and easily fall off during use, affecting the anti-corrosion effect.

[0015] (2) The present invention utilizes the characteristic that the fixed block 2 can rotate. When the fixed block 2 rotates and drives the slider 2 to rotate, since the slider 2 and the fixed block 1 are distributed at a certain angle, an air flow will be generated in the forward direction of the device during rotation, blowing the particles scraped off by the scraper when cleaning the inner wall and the dust particles raised to the front of the device, so as to avoid the scraped particles from accumulating on the scraper. If the amount of accumulation is large, they may be missed in the spraying area, and the dust and flying particles raised during scraping will mix with the sprayed paint and affect the spraying effect.

[0016] (3) The present invention utilizes the characteristic that the rotation of the fixed block 2 generates centrifugal force. When the slider 2 is extended outward under the action of the centrifugal force, the gas pressure in the cavity decreases, and the gas will have a pulling effect on the slider 2. At the same time, before contacting the inner wall of the pipe, the scraper will also drive the slider 3 to slide on the inner wall of the cavity 2, squeezing the spring close to the scraper side and stretching the spring on the other side of the slider 3. During the contact with the inner wall of the pipe, the opposite is true, stretching the spring close to the scraper side and squeezing the spring on the other side of the slider 3, so as to avoid excessive instantaneous impact force when the scraper rotates and contacts the inner wall of the pipe, affecting the stability of the device and causing damage to the device and the inner wall of the pipe.

[0017] (4) The present invention places the device in the pipeline and adjusts the size by adjusting the diameter of the pulley's circumscribed circle. The inner diameter of the pipeline is the diameter of the pulley's circumscribed circle. When adjusting the position of the slider five, the slide groove three is made close to the inner wall of the pipeline. The limit rod slides on the inner wall of the slide groove three to squeeze the gas inside the slide groove three. It has a certain telescopic ability when encountering a bend. After the slider five moves to the appropriate position, the bolt is tightened. The bolt squeezes the slider six to slide on the inner wall of the cavity three, driving the slider six to squeeze the gas inside the cavity three. The increase in the gas pressure inside the cavity three will squeeze the limit block to slide outward and squeeze the side wall of the fixed block one, thereby limiting the slider five, thereby completing the adjustment and fixation of the device, so that the device can be adjusted to adapt to pipelines of different sizes and has a certain degree of self-adaptation to bends.

[0026] For example 2, please refer to Figure 4-Figure 8 The present invention is a device for spraying an anti-corrosion coating on the inner wall of a waste incinerator tube row. Based on Example 1, the fixing component 11 includes a plurality of pulleys 115 rotatably connected to the side wall of the support arm 114, a plurality of teeth 116 are provided on the inner wall of the slider 113, and a traction block 117 is rotatably connected to the side wall of the traction block.

[0027] The driving assembly 12 includes a gear 123 fixedly connected to the side wall of the extension portion of the rotating shaft 122, a gear 2 124 rotatably connected to the side wall of the fixed block 112, the side wall of the gear 2 124 meshingly connected with the side wall of the gear 1 123, the side wall of the gear 2 124 meshingly connected with the side wall of the tooth 116, a nozzle 125 is provided on the side wall of the slider 113, and the rotating shaft 122 is rotatably connected to the side wall of the slider 113.

[0028] The cleaning assembly 21 includes a scraper 215 slidably connected to the side wall of the second slider 214 , and the cavity 212 is connected to the side wall of the first slide 213 .

[0029] The protection component 22 includes a plurality of springs 222 fixedly connected to the inner wall of the second cavity 221 . A third slider 223 is slidably connected in the second cavity 221 . The side wall of the scraper 215 is fixedly connected to the side wall of the third slider 223 .

[0030] The adjustment component 31 includes a slider 4 312 rotatably connected to a limit rod 313 at the side wall, a slider 5 314 slidably connected to the side wall of the fixed block 112, a slide groove 315 is provided on the side wall of the slider 5 314, and the side wall of the limit rod 313 is slidably connected to the inner wall of the slide groove 3 315.

[0031] A cavity three 321 is opened on the inner wall of the slider five 314, and a slider six 323 is slidably connected to the inner wall of the cavity three 321. The bolt 322 extends into the cavity three 321. Two limit blocks 324 are slidably connected to the inner wall of the cavity three 321. The limit blocks 324 extend to the outside of the slider five 314. The side wall of the slider six 323 is slidably connected to the side wall of the fixed block one 112.

[0032] First, place the device in the pipe 111, and adjust the angle between the support arm 114 and the fixed block 112 by adjusting the position of the slider 5 314, thereby adjusting the diameter of the circumscribed circle of the pulley 115. The inner diameter of the pipe is the diameter of the circumscribed circle of the pulley 115. When adjusting the position of the slider 5 314, the chute 315 is made to fit closely to the inner wall of the pipe 111. The limit rod 313 slides on the inner wall of the chute 315 to squeeze the gas inside the chute 315. When encountering a bend, it has a certain degree of expansion and contraction. After 314 moves to the appropriate position, tighten the bolt 322. The bolt 322 will squeeze the slider six 323 to slide on the inner wall of the cavity three 321, driving the slider six 323 to squeeze the gas inside the cavity three 321. The increase in the gas pressure inside the cavity three 321 will squeeze the limit block 324 to slide outward and squeeze the side wall of the fixed block one 112, thereby limiting the slider five 314, thereby completing the adjustment and fixation of the device, so that the device can be adjusted to adapt to pipes of different sizes and has a certain degree of adaptability to curves.

[0033] After the adjustment is completed, the motor 121 is started, and the motor drives the rotating shaft 122 to rotate, the rotating shaft 122 drives the gear 1 123 to rotate, the gear 1 123 drives the gear 2 124 to rotate, the gear 2 124 drives the gear 2 124 to rotate, the gear 2 124 drives the slider 1 113 to rotate, and the slider 113 drives the pulley 115 to rotate and spray. Because the side wall of the extended part of the rotating shaft 122 is fixedly connected to the fixed block 211, the rotating shaft 122 also drives the fixed block 211 to rotate. When the fixed block 211 rotates, the slider 2 214 slides outward under the action of centrifugal force until the scraper 215 contacts the inner wall of the pipe. After contacting the inner wall, the scraper 215 will scrape the inner wall of the pipe to scrape off the welding slag and dust particles remaining on the inner wall of the pipe. Because the scraper 215 is tilted at a certain angle to the fixed block 112, it will rotate after scraping the inner wall to push the scraped welding slag and dust particles to follow the device forward until they are pushed out of the pipe, so that the inner wall of the pipe can be cleaned before spraying to avoid areas with residual metal particles and dust particles in the pipe that affect the adhesion between the spray paint and the inner wall of the pipe. After spraying, a valley will be formed between the paint and the pipe, which is prone to partial shedding during use and affects the anti-corrosion effect.

[0034] When the fixed block 211 rotates and drives the slider 214 to rotate, since the slider 214 and the fixed block 1 112 are distributed at a certain angle, an air flow will be generated in the forward direction of the device during rotation, blowing the particles scraped off by the scraper 215 when cleaning the inner wall and the dust particles raised to the front of the device, so as to prevent the scraped particles from accumulating on the scraper 215. If the amount of accumulation is large, they may be missed in the spraying area, and the dust and flying particles raised during scraping will mix with the sprayed paint and affect the spraying effect.

[0035] When slider 214 extends outward under the action of centrifugal force, the gas pressure in cavity 212 decreases, and the gas will have a pulling effect on slider 214. At the same time, before contacting the inner wall of pipe 111, scraper 215 will also drive slider 3 223 to slide on the inner wall of cavity 221, squeezing the spring 222 close to the scraper 215 side and stretching the spring 222 on the other side of slider 3 223. In the process of contacting the inner wall of pipe 111, the opposite is true, stretching the spring 222 close to the scraper 215 side and squeezing the spring 222 on the other side of slider 3 223, so as to avoid excessive impact force when scraper 215 rotates and contacts the inner wall of the pipe, affecting the stability of the device and causing damage to the device and the inner wall of the pipe.

[0036] A specific application of this embodiment is as follows: first, the device is placed in the pipe 111, and the angle between the support arm 114 and the fixed block 112 is adjusted by adjusting the position of the slider 5 314, thereby adjusting the diameter of the circumscribed circle of the pulley 115. The inner diameter of the pipe is the diameter of the circumscribed circle of the pulley 115. When adjusting the position of the slider 5 314, the chute 3 315 is made to be close to the inner wall of the pipe 111. The limit rod 313 slides on the inner wall of the chute 3 315 to squeeze the gas inside the chute 3 315, and has a certain degree of expansion and contraction when encountering a bend. Force, after the slider five 314 moves to the appropriate position, tighten the bolt 322, the bolt 322 will squeeze the slider six 323 to slide on the inner wall of the cavity three 321, and drive the slider six 323 to squeeze the gas inside the cavity three 321. The increase in the gas pressure inside the cavity three 321 will squeeze the limit block 324 to slide outward and squeeze the side wall of the fixed block one 112, thereby limiting the slider five 314, thereby completing the adjustment and fixation of the device, so that the device can be adjusted to adapt to pipes of different sizes, and has a certain degree of adaptability to curves.

[0037] After the adjustment is completed, the motor 121 is started, and the motor drives the rotating shaft 122 to rotate, the rotating shaft 122 drives the gear 1 123 to rotate, the gear 1 123 drives the gear 2 124 to rotate, the gear 2 124 drives the gear 2 124 to rotate, the gear 2 124 drives the slider 1 113 to rotate, and the slider 113 drives the pulley 115 to rotate and spray. Because the side wall of the extended part of the rotating shaft 122 is fixedly connected to the fixed block 211, the rotating shaft 122 also drives the fixed block 211 to rotate. When the fixed block 211 rotates, the slider 2 214 slides outward under the action of centrifugal force until the scraper 215 contacts the inner wall of the pipe. After contacting the inner wall, the scraper 215 will scrape the inner wall of the pipe to scrape off the welding slag and dust particles remaining on the inner wall of the pipe. Because the scraper 215 is tilted at a certain angle to the fixed block 112, it will rotate after scraping the inner wall to push the scraped welding slag and dust particles to follow the device forward until they are pushed out of the pipe, so that the inner wall of the pipe can be cleaned before spraying to avoid areas with residual metal particles and dust particles in the pipe that affect the adhesion between the spray paint and the inner wall of the pipe. After spraying, a valley will be formed between the paint and the pipe, which is prone to partial shedding during use and affects the anti-corrosion effect.

[0038] When the fixed block 211 rotates and drives the slider 214 to rotate, since the slider 214 and the fixed block 1 112 are distributed at a certain angle, an air flow will be generated in the forward direction of the device during rotation, blowing the particles scraped off by the scraper 215 when cleaning the inner wall and the dust particles raised to the front of the device, so as to prevent the scraped particles from accumulating on the scraper 215. If the amount of accumulation is large, they may be missed in the spraying area, and the dust and flying particles raised during scraping will mix with the sprayed paint and affect the spraying effect.

[0039] When slider 214 extends outward under the action of centrifugal force, the gas pressure in cavity 212 decreases, and the gas will have a pulling effect on slider 214. At the same time, before contacting the inner wall of pipe 111, scraper 215 will also drive slider 3 223 to slide on the inner wall of cavity 221, squeezing the spring 222 close to the scraper 215 side and stretching the spring 222 on the other side of slider 3 223. In the process of contacting the inner wall of pipe 111, the opposite is true, stretching the spring 222 close to the scraper 215 side and squeezing the spring 222 on the other side of slider 3 223, so as to avoid excessive impact force when scraper 215 rotates and contacts the inner wall of the pipe, affecting the stability of the device and causing damage to the device and the inner wall of the pipe.
