[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0027] Refer to Figures 1-6 As shown in

[0028] , a scraper conveyor for conveying bottom ash of a furnace includes a scraper conveyor 1 and a scraper 3. A cooling component 2 is arranged inside the scraper conveyor 1. The cooling component 2 includes a rack 201 fixedly installed on the inner wall of the scraper conveyor 1. The inner bottom wall of the scraper 3 is rotatably connected with a connecting rod 202. A first gear 203 meshed with the rack 201 is fixedly installed on the outer wall of the connecting rod 202. Two rotating rods 204 are arranged inside the scraper 3. A transmission belt 205 is connected between the connecting rod 202 and one of the rotating rods 204. A plurality of fan blades 206 are fixedly installed on the outer wall of the rotating rod 204. A belt 207 is connected between the two rotating rods 204.

[0029] Refer to Figure 4 , a through groove 10 is opened on one side of the scraper 3. The first gear 203 is located inside the through groove 10, and the rack 201 does not contact the scraper 3.

[0030] The through slot 10 provides space for the first gear 203 to extend out of the scraper 3, enabling the rack 201 to drive the first gear 203 to rotate without contacting the scraper 3. The rack 201 does not contact the scraper 3, avoiding friction and wear between the rack 201 and the scraper 3.

[0031] Refer to Figures 2-3 , a chamber 5 is provided inside the scraper 3, with water in the chamber 5. A rotating shaft 7 is fixedly installed on the outer wall of the rotating rod 204, and a blade 8 is fixedly installed on the outer wall of the rotating shaft 7. The rotating shaft 7 and the blade 8 are located inside the chamber 5.

[0032] The water in the chamber 5 not only cools the bottom and the outer wall of the scraper 3, but also can cool the chain at the bottom of the scraper 3. While the rotating rod 204 rotates, it drives the rotating shaft 7 and the blade 8 in the chamber 5 to rotate together. The rotating blade 8 can accelerate the flow of water in the chamber 5, enabling the enclosed scraper conveyor 1 to dissipate heat faster.

[0033] Refer to Figures 2-4 , a baffle 4 is fixedly installed on the inner wall of the scraper 3. The rotating rod 204 is rotatably connected to the baffle 4, and the chamber 5 is located between the baffle 4 and the inner bottom wall of the scraper 3.

[0034] The baffle 4 supports the rotating rod 204 and separates the chamber 5 from the scraper 3, preventing the water in the chamber 5 from flowing into the enclosed scraper conveyor 1 through the through slot 10.

[0035] Refer to Figures 2-3 , two sealing rings 6 are fixedly installed on the outer wall of the rotating rod 204. One sealing ring 6 is located on the top of the baffle 4, and the other sealing ring 6 is located on the bottom of the baffle 4. The sealing rings 6 are located at the connection between the rotating rod 204 and the baffle 4.

[0036] The sealing rings 6 seal the connection between the rotating rod 204 and the baffle 4, preventing the water in the chamber 5 from seeping above the baffle 4 and causing the water to flow out of the through slot 10 to the outside of the scraper 3, and avoiding the furnace bottom ash slag from clumping when it touches the water.

[0037] Refer to Figures 4-5 , a heat dissipation plate 9 is fixedly installed on the inner wall of the scraper 3. The heat dissipation plate 9 is located on the top of the scraper 3.

[0038] The heat dissipation plate 9 seals the top of the scraper 3, enabling the air blown out by the fan blade 206 in the scraper 3 to be dissipated through the heat dissipation plate 9.

[0039] Refer to Figure 6, a support rod 11 is rotatably connected to the top of the baffle 4. A second gear 12 engaged with the first gear 203 is fixedly installed on the outer wall of the support rod 11. A worm 13 is fixedly installed at the top of the support rod 11. A support rod 15 is arranged on one side of the worm 13. A worm gear 16 engaged with the worm 13 is fixedly installed on the outer wall of the support rod 15. A plurality of blade plates 17 are fixedly installed on the outer wall of the support rod 15. The blade plates 17 correspond to the first gear 203 and the rack 201.

[0040] When the first gear 203 rotates, it drives the second gear 12 to rotate. The support rod 11 and the worm 13 are rotated through the second gear 12. The rotation of the worm 13 drives the worm gear 16 to rotate. After the worm gear 16 rotates, it will drive the support rod 15 and the blade plates 17 to rotate. The wind blown out by the blade plates 17 can cool the first gear 203 and the rack 201, avoiding the situation that the high-temperature furnace bottom ash falls on the rack 201 and the first gear 203, resulting in thermal deformation of the rack 201 and the first gear 203. At the same time, the wind blown out by the blade plates 17 can also blow off the high-temperature furnace bottom ash scattered between the rack 201 and the first gear 203, avoiding the high-temperature furnace bottom ash getting stuck between the rack 201 and the first gear 203 and affecting the transmission effect of the rack 201 and the first gear 203.

[0041] Refer to Figure 6 , a partition plate 14 is fixedly installed at the top of the baffle 4. One end of the support rod 15 away from the blade plates 17 is rotatably connected to the outer wall of the partition plate 14.

[0042] The partition plate 14 supports the support rod 15, provides a support point for the support rod 15, and makes the blade plates 17 and the support rod 15 more stable when rotating.

[0043] Working principle:

[0044] When the scraper 3 moves along the chain in the drag conveyor 1, when the scraper 3 moves along the rack 201, the first gear 203 will rotate along the rack 201. After the first gear 203 rotates, it drives the connecting rod 202 to rotate. The connecting rod 202 drives one of the rotating rods 204 to rotate through the transmission belt 205. The rotating rod 204 drives the other rotating rod 204 to rotate through the belt 207. The rotating rod 204 rotates to drive the fan blade 206 to rotate. The rotating fan blade 206 will blow out wind, and the wind cools the scraper 3 in direct contact with the high-temperature furnace bottom ash, improving the heat dissipation effect of the scraper 3 and reducing the situation of thermal deformation of the scraper 3.

[0045] When the first gear 203 rotates, it drives the second gear 12 to rotate. Through the second gear 12, the support rod 11 and the worm 13 are driven to rotate. The rotation of the worm 13 drives the worm wheel 16 to rotate. After the worm wheel 16 rotates, it drives the support rod 15 and the blade 17 to rotate. The wind blown by the blade 17 can cool the first gear 203 and the rack 201, avoiding the situation that the high-temperature furnace bottom ash falls on the rack 201 and the first gear 203, resulting in thermal deformation of the rack 201 and the first gear 203. At the same time, the wind blown by the blade 17 can also blow off the high-temperature furnace bottom ash scattered between the rack 201 and the first gear 203, avoiding the high-temperature furnace bottom ash getting stuck between the rack 201 and the first gear 203 and affecting the transmission effect of the rack 201 and the first gear 203.
