Description
Technical Field
[0001] The utility model relates to the technical field of grate bar and grate gap cleaning equipment, and particularly relates to a grate bar and grate gap cleaning structure for a grate cooler. Background Technique
[0002] The grate cooler is an important main equipment in the clinker burning system of a cement plant. Its main function is to cool and convey cement clinker. During the transportation and cooling of the clinker, grate bars are required. The clinker is transported through the movement of the grate bars. At the same time, the cooling air output by the cooling fan passes through pipelines, grate chambers, and directly contacts the clinker through the grate gaps of the grate bars to reduce the temperature of the clinker, so as to achieve the purpose of cooling and transporting the clinker.
[0003] However, after long-term use, clinker particles are likely to adhere to and accumulate at the grate gaps of the grate bars, blocking the output of the cooling air. Most of the existing cleaning devices for the grate gaps of the grate bars blow air through high-pressure nozzles to blow the clinker particles in the grate gaps, making the clinker particles loose, and then sweeping out the loose clinker particles in the grate gaps through a cleaning brush to complete the cleaning of the grate gaps of the grate bars. However, due to the different solidification degrees of the clinker particles adhering to the grate gaps, using this method to clean the clinker particles in the grate gaps of the grate bars cannot completely clean out the clinker particles in the grate gaps, and there will be some clinker particles remaining in the grate gaps, affecting the cleaning quality of the grate gaps of the grate bars. Therefore, the technical personnel in the field provide a grate bar and grate gap cleaning structure for a grate cooler to solve the problems raised in the above background technique.

[0023] Combined with Figures 1-6As shown in the figure, a cleaning structure for the grate gaps of a grate cooler includes: a workbench 1. Vertical seats 11 are arranged at both ends of the top of the workbench 1. And an adjusting mechanism 2 is drivingly arranged between the two vertical seats 11 above the workbench 1. The adjusting mechanism 2 includes an adjusting plate 21 and an adjusting frame 22. Among them, the adjusting frame 22 is slidably installed below the adjusting plate 21. And a fixed frame 23 is arranged at the middle position of the bottom of the adjusting plate 21. A cylinder 24 is arranged inside the fixed frame 23. The output end of the cylinder 24 is provided with an extension rod 241. The extension rod 241 penetrates through the fixed frame 23 and is installed on the top of the adjusting frame 22. And a slide rod 25 is arranged inside the adjusting frame 22. A plurality of scraping plates 3 are evenly arranged on the outer wall of the slide rod 25. A partition plate 31 is arranged at the middle position inside the scraping plate 3. And empty slots 301 are arranged on both sides of the partition plate 31 inside the scraping plate 3. An extension plate 32 is slidably arranged inside the empty slot 301. The extension plate 32 penetrates through the scraping plate 3 and extends to its outside. An inclined surface 321 for pushing its displacement is arranged at one end of the extension plate 32 located outside the scraping plate 3. A spring 33 is arranged between one end of the extension plate 32 located inside the empty slot 301 and the inner wall of the empty slot 301. And a vertical plate 34 is arranged at the top of the scraping plate 3. The vertical plate 34 is slidably installed on the outer wall of the slide rod 25. Limiting nuts 26 for limiting its position are arranged on both sides of the vertical plate 34 on the outer wall of the slide rod 25.
[0024] In one embodiment, when cleaning the grate gaps, the cylinder 24 can be first used to drive the extension rod 241 at its output end to extend. The extension rod 241 pushes the adjusting frame 22 to displace downward. The adjusting frame 22 slides downward at the bottom of the adjusting plate 21 through the cooperation of the slider 222 on the inner side plate 221 installed on it and the chute 212 on the outer side plate 211 installed on the adjusting plate 21. Then, the adjusting frame 22 sliding downward drives the scraping plate 3 installed on it through the slide rod 25 to displace downward. The scraping plate 3 is inserted into the grate gaps. The extension plates 32 extending to both sides of the scraping plate 3 are tightly attached to the inner walls of the gaps under the elastic force of the spring 33. Finally, the motor 12 is used to drive the screw rod 13 to rotate forward and backward. The screw rod 13 drives the adjusting plate 21 installed on it through the thread groove 213 to displace repeatedly on the outer wall of the positioning rod 14 through the sliding hole 214. And drives the scraping plate 3 installed on the adjusting plate 21 through the slide rod 25 and the adjusting frame 22 to displace repeatedly in the gaps. The solidified clinker particles in the gaps are scraped off by the scraping plate 3 during repeated displacement. In this way, the cleaning of the grate gaps is completed. The clinker particles in the gaps can be scraped off, avoiding the trouble that the clinker in the gaps cannot be completely removed due to its solidification, and ensuring the cleaning effect of the grate gaps.
[0025] In one embodiment, when cleaning the grate gaps of different models of grate plates, the vertical plate 34 can be slid on the outer wall of the slide bar 25 through the through hole 341, so that the vertical plate 34 drives the connected scraper 3 to displace, adjust the positions of the scrapers 3 on the slide bar 25, make each scraper 3 perpendicular to the directly above of the grate gap, then turn the limit nuts 26 on the slide bar 25 located on both sides of the vertical plate 34, screw the two limit nuts 26 tightly on the end face of the vertical plate 34 to limit the position of the vertical plate 34 and prevent the vertical plate 34 from displacing on the slide bar 25, thus completing the limit of the scraper 3 after adjusting the position. In this way, the position adjustment of the scraper 3 is completed, and the scraper 3 can be adjusted according to the position change of the grate gaps on different models of grate plates, making the scraper 3 perpendicular to the directly above of the grate gap, avoiding the trouble that the scraper 3 can only clean the grate gaps of a specified model due to the fixed position of the scraper 3, and realizing the cleaning of the grate gaps at different positions on the grate plate.
[0026] In one embodiment, when inserting the scraper 3 into the grate gap to clean the clinker particles adhering to its inner wall, the extension plates 32 located on both sides of the scraper 3 can extend out of the empty groove 301 under the elastic force of the spring 33 and closely adhere to the inner wall of the grate gap, and let the extension plates 32 scrape the clinker particles on the inner wall of the grate gap following the displacement of the scraper 3, realizing the cleaning of grate gaps with different widths.
[0027] In one embodiment, when inserting the scraper 3 into the grate gap, first let the extension plates 32 located on both sides of the scraper 3 follow its downward displacement, so that the bottom ends of the extension plates 32 are inserted into the grate gap, then make the inclined surfaces 321 on the extension plates 32 contact with the top inner wall of the grate gap, and let the extension plates 32 slide towards the bottom of the grate gap through the inclined surfaces 321. At the same time, the extension plates 32 are squeezed by the grate plate and slide into the empty groove 301, then the scraper 3 and the extension plates 32 can be inserted into the grate gap, enabling the extension plates 32 to closely adhere to the inner wall of the grate gap under the elastic force of the spring 33, preventing the extension plates 32 from interfering with the grate plate, and avoiding the situation that the scraper 3 cannot be inserted into the grate gap due to the interference between the extension plates 32 and the grate plate, ensuring the use of the scraper 3.
[0028] The working principle of the present utility model is as follows: When cleaning the clinker particles in the grate slots of the grate plate, the grate plate can be installed on the workbench 1, and the vertical plate 34 can slide on the outer wall of the slide bar 25 through the through hole 341, so that the vertical plate 34 drives the connected scraper 3 to displace, adjust the positions of the scrapers 3 on the slide bar 25, make each scraper 3 perpendicular to the directly above of the grate slot, then turn the limit nuts 26 on the slide bar 25 on both sides of the vertical plate 34, screw the two limit nuts 26 tightly on the end face of the vertical plate 34 to limit the position of the vertical plate 34 and prevent the vertical plate 34 from displacing on the slide bar 25, thus completing the limitation of the scraper 3 after adjusting the position. Then, the cylinder 24 drives the extension rod 241 at its output end to extend, and the extension rod 241 pushes the adjustment frame 22 to displace downward, so that the adjustment frame 22 slides downward at the bottom of the adjustment plate 21 through the cooperation between the slider 222 on the inner side plate 221 installed thereon and the chute 212 on the outer side plate 211 installed on the adjustment plate 21. Then, the downward-sliding adjustment frame 22 drives the scraper 3 installed thereon through the slide bar 25 to displace downward, inserts the scraper 3 into the grate slot of the grate plate, and makes the extension plates 32 extending to both sides of the scraper 3 closely adhere to the inner wall of the grate slot under the elastic force of the spring 33. Finally, the motor 12 drives the lead screw 13 to rotate forward and backward, so that the lead screw 13 drives the adjustment plate 21 installed thereon through the thread groove 213 to repeatedly displace through the slide hole 214 on the outer wall of the positioning rod 14, and drives the scraper 3 installed on the adjustment plate 21 through the slide bar 25 and the adjustment frame 22 to repeatedly displace in the grate slot. The solidified clinker particles in the grate slot are scraped off by the repeatedly-displacing scraper 3, thereby completing the cleaning of the grate slot of the grate plate. It can adjust the position of the scraper 3 according to the model of the grate plate, insert the scraper 3 into the grate slots with different widths to clean the clinker particles adhering to the inner wall thereof, which not only avoids the situation that the clinker in the grate slot cannot be completely removed due to its solidification, but also avoids the trouble of needing to replace different models of scrapers 3 to clean the grate slots with different widths of the grate plate, improves the cleaning quality of the grate slot of the grate plate, is applicable to the cleaning of the grate slots with different models of the grate plate, and has strong practicability.
