Description

Technical Field

[0001] This utility model relates to the field of slag removal machine technology, and in particular to a novel boiler slag removal machine. Background Technology

[0002] Thermal power plants are factories that use combustibles as fuel to produce electricity. The slag remover is the main equipment used for slag removal in thermal power plants. Most of them are scraper slag removers. The slag remover is installed below the slag outlet of the furnace. The slag is cooled in a water tank. After the ash is cooled, it settles at the bottom of the tank and is gradually moved out by the movement of the conveying scraper.

[0003] Utility model disclosure CN217464472U discloses a novel boiler slag removal machine, comprising a body, a driver, and a filter. A conveyor belt is installed on the inner wall of the body, and multiple sets of scrapers are installed on the outer wall of the conveyor belt. Two sets of sliding grooves are installed on the inner wall of each scraper, along with a driver and multiple sets of limiting rings. Sliding rods are installed at the top and bottom of the sliding frame. This novel boiler slag removal machine cleans the residue adsorbed on the outer wall of the scrapers using the driver and the scrapers. During cleaning, a first telescopic rod moves a sealing plate, causing the output end of the driver to rotate and move the conveyor belt. The moving conveyor belt moves the sliding frame, which in turn moves the sliding rods. The moving sliding rods then move the scrapers, which in turn clean the residue adsorbed on the outer wall of the scrapers, achieving rapid cleaning of the residue.

[0004] The slag removal machine described above filters the sewage inside the machine through a No. 1 filter plate and a No. 2 filter plate. However, some impurities are stored between the No. 1 filter plate and the No. 2 filter plate after filtration. They tend to accumulate during long-term operation of the machine and are not easy to clean. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of boiler slag removal machine to solve the problem mentioned in the background art that impurities tend to accumulate during long-term operation of the machine and are difficult to clean.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel boiler slag removal machine includes a body on which several conveying plates for transporting coal slag are installed. A cooling tank is installed on the body, and a base is installed at the bottom of the cooling tank. A first filter plate is installed between the body and the cooling tank. A second filter plate and a third filter plate are arranged below the first filter plate. The second and third filter plates are both installed on the inner wall of the cooling tank. Slag discharge grooves are opened on the second and third filter plates. Scrapers are installed on the top wall of the second and third filter plates. The two ends of the two scrapers are connected to the same connecting block. A threaded rod is threadedly connected to one of the connecting blocks. One end of the threaded rod is rotatably connected to the cooling tank, and the other end passes through the body and is connected to a servo motor. The servo motor is installed on the outer wall of the cooling tank.

[0007] Preferably, the first filter plate, the second filter plate, and the third filter plate are each provided with a plurality of through holes, and the size of the through holes on the first filter plate, the second filter plate, and the third filter plate decreases sequentially.

[0008] Preferably, the cooling groove has a connecting groove on one side wall parallel to the threaded rod, and the threaded rod and the connecting block threaded thereon are both adapted to fit in the connecting groove.

[0009] Preferably, the cooling tank has a rotating groove and a rotating hole, the rotating groove is connected to the connecting groove, and the two ends of the threaded rod are respectively rotatably adapted in the rotating groove and the rotating hole.

[0010] Preferably, a slag storage box is connected to the bottom wall of the third filter plate. The slag storage box is located directly below the slag discharge trough, and a slag discharge pipe is installed at the bottom of the slag storage box. The top of the slag discharge pipe is connected to the slag storage box, and its top passes through and is exposed outside the cooling trough.

[0011] Preferably, a limiting groove is formed on the side wall of the cooling tank away from the threaded rod, and a limiting block is slidably installed in the limiting groove. The limiting block is installed on the connecting block away from the threaded rod.

[0012] Preferably, a water pump is installed in the cooling tank, the water pump is located below the third filter plate and a drain pipe is connected to it, and the end of the drain pipe away from the water pump is exposed outside the cooling tank.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, a conveyor plate carries away large coal slag particles, while the remaining small coal slag particles fall onto a second filter plate via a first filter plate. The finer particles on the second filter plate then fall onto a third filter plate. At this point, a servo motor is activated to clean the unfiltered coal slag remaining on the second and third filter plates. The servo motor drives a threaded rod to rotate synchronously, causing a connecting block threaded onto the threaded rod to move towards the slag discharge trough. This, in turn, moves two scrapers mounted on the connecting block in the same direction, causing them to move on the second and third filter plates respectively. This pushes the coal slag remaining on the second and third filter plates towards the slag discharge trough, thus completing the cleaning of the coal slag in the slag remover. This slag remover can filter residual coal slag in the cooling water of the cooling tank, allowing the filtered cooling water to be discharged to the outside, reducing environmental pollution. Simultaneously, it cleans the second and third filter plates, preventing the accumulation of residue in the cooling tank and further extending the machine's service life. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4A novel boiler slag removal machine includes a body 1, on which several conveying plates 2 for transporting coal slag are installed. A cooling tank 3 is installed on the body 1, and a base 20 is installed at the bottom of the cooling tank 3. A first filter plate 4 is installed between the body 1 and the cooling tank 3. A second filter plate 5 and a third filter plate 6 are arranged below the first filter plate 4. The second filter plate 5 and the third filter plate 6 are both installed on the inner wall of the cooling tank 3. A slag discharge trough 11 is opened on the second filter plate 5 and the third filter plate 6. A scraper 7 is installed on the top wall of the second filter plate 5 and the third filter plate 6. The two ends of the two scrapers 7 are connected to the same connecting block 8. A threaded rod 9 is threadedly connected to one of the connecting blocks 8. One end of the threaded rod 9 is rotatably connected to the cooling tank 3, and the other end passes through the body 1 and is connected to a servo motor 10. The servo motor 10 is installed on the outer wall of the cooling tank 3.

[0022] When the slag remover needs cleaning, during operation, the conveyor plate 2 carries away large slag particles. The remaining small slag particles fall onto the second filter plate 5 via the first filter plate 4, and the fine particles on the second filter plate 5 fall onto the third filter plate 6. At this time, the servo motor 10 is activated to clean the unfiltered slag remaining on the second and third filter plates 5 and 6. When the servo motor 10 is running, it drives the threaded rod 9 to rotate synchronously, causing the connecting block 8 threaded onto the threaded rod 9 to move towards the slag discharge trough 11, thereby driving the two scrapers 7 installed on the connecting block 8 to move along the slag discharge trough 11. Moving in the same direction, the two scrapers 7 move on the second filter plate 5 and the third filter plate 6 respectively, thereby pushing the coal slag remaining on the second filter plate 5 and the third filter plate 6 towards the slag discharge trough 11, thus completing the cleaning of the coal slag in the slag remover. This slag remover can filter the coal slag remaining in the cooling water in the cooling tank 3, so that the cooling water can be discharged to the outside after filtration, reducing environmental pollution. At the same time, it cleans the second filter plate 5 and the third filter plate 6, avoiding the situation where the residue in the cooling tank 3 is difficult to clean, and further extending the service life of the machine.

[0023] Specifically, in this embodiment, the first filter plate 4, the second filter plate 5, and the third filter plate 6 are each provided with a number of through holes. The size of the through holes on the first filter plate 4, the second filter plate 5, and the third filter plate 6 decreases sequentially, so that the coal slag falling on the first filter plate 4 and the second filter plate 5 can fall onto the next layer of filter plate through the through holes, thereby completing the fine filtration of the coal slag and realizing the separation of coal slag from cooling water.

[0024] Specifically, in this embodiment, a connecting groove 12 is provided on one side wall of the cooling tank 3 parallel to the threaded rod 9. The threaded rod 9 and the connecting block 8 threadedly connected thereon are both adapted in the connecting groove 12, so that the threaded rod 9 and the connecting block 8 threadedly connected thereon can be installed on the cooling tank 3 through the connecting groove 12, thereby facilitating the movement of the scraper 7 by the movement of the threaded rod 9 to achieve the purpose of cleaning the residue.

[0025] Specifically, in this embodiment, the cooling tank 3 is provided with a rotating groove 13 and a rotating hole 14. The rotating groove 13 is connected to the connecting groove 12. The two ends of the threaded rod 9 are respectively rotatably adapted in the rotating groove 13 and the rotating hole 14, so that the threaded rod 9 can be rotatably installed on the cooling tank 3 through the rotating groove 13 and the rotating hole 14, thereby ensuring that the servo motor 10 can drive the threaded rod 9 to rotate on the cooling tank 3.

[0026] Specifically, in this embodiment, a slag storage box 15 is connected to the bottom wall of the third filter plate 6. The slag storage box 15 is located directly below the slag discharge trough 11, and a slag discharge pipe 21 is installed at the bottom of the slag storage box 15. The top of the slag discharge pipe 21 is connected to the slag storage box 15, and its top passes through and is exposed outside the cooling tank 3, so that the coal slag on the second filter plate 5 and the third filter plate 6 can enter the slag storage box 15 through the slag discharge trough 11, and then be discharged to the outside of the slag removal machine for centralized processing via the slag discharge pipe 21.

[0027] Specifically, in this embodiment, a limiting groove 16 is formed on the side wall of the cooling tank 3 away from the threaded rod 9. A limiting block 17 is slidably installed in the limiting groove 16. The limiting block 17 is installed on the connecting block 8 away from the threaded rod 9, so that the connecting block 8 away from the threaded rod 9 can be slidably connected to the limiting groove 16 through the limiting block 17. This ensures that the two scrapers 7 can only move along the direction of the limiting groove 16, thereby preventing the threaded rod 9 from driving the scrapers 7 to rotate.

[0028] Specifically, in this embodiment, a water pump 18 is installed in the cooling tank 3. The water pump 18 is located below the third filter plate 6 and is connected to a drain pipe 19. The end of the drain pipe 19 away from the water pump 18 is exposed outside the cooling tank 3, so that the filtered cooling water can be discharged from the slag remover through the water pump 18 and the drain pipe 19, which facilitates the cleaning of the slag remover.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
