Description

Technical Field

[0001] This invention relates to the field of clean coal utilization and coal gasification technology, specifically to a gas-fired combustion gasifier that is easy to clean. Background Technology

[0002] The heat of reaction inside the gasifier is provided by the combustion of carbon and oxygen in the gasifying agent. This combustion heating method results in a large amount of carbon being lost through combustion. The combustion of carbon and raw materials produces a large amount of dust. Most of the dust is discharged through the ash outlet at the bottom of the gasifier, but some dust still adheres to the inner wall of the gasifier. This dust buildup leads to a thicker and thicker layer of dirt on the inner wall, interfering with the combustion efficiency during the gasification process. The continuous dust generation during combustion makes manual cleaning of the gasifier cumbersome, labor-intensive, and inefficient. Consequently, cleaning time accounts for more of the gasifier's operating time, impacting its lifespan.

[0003] A prior art biomass gasifier (Chinese patent application number CN201010123374.4) discloses an ash removal device comprising a first rotatable flap disposed below the gasification layer of the furnace body and a closed second rotatable flap disposed at the ash outlet of the furnace body. A space for ash retention exists between the first and second rotatable flaps. A movable ash removal box is located below the ash outlet of the furnace body. The first and second rotatable flaps are equipped with manual or electric rotating shafts that respectively drive their rotation. These shafts are mounted on bearing seats within the furnace body. The above process can be carried out continuously within a closed space without affecting the normal operation of the gasifier. It is simple to operate, has a fast ash removal speed, high working efficiency, and does not pollute the environment.

[0004] The aforementioned ash removal device automatically collects and discharges the ash generated during combustion by setting up a movable ash removal box. However, it can only be used to collect ash that falls naturally by gravity and cannot clean the ash adhering to the inner wall of the gasifier. The cleaning cloth is not thorough. Summary of the Invention

The upper and lower cleaning components can clean the ash outlet nozzle and the inner wall surface of the gasifier body while driving the upper connecting plate to move up and down.

[0007] As a further embodiment of the present invention, the lower cleaning assembly includes a protective cover and a connecting shaft. The protective cover wraps around the surface of the inner rotating ring. The connecting shaft is rotatably mounted on the inner rotating ring.

An internal tooth is fixedly mounted on the surface of the inner rotating ring. The internal tooth meshes with the driving gear. A rotating motor is fixedly mounted inside the protective cover.

[0009] As a further embodiment of the present invention, the upper cleaning assembly includes a threaded component, which is threadedly connected to the threaded rod. A plurality of connecting plates are fixedly installed on the outer surface of the threaded component. An inclined partition is fixedly installed on one end of the connecting plate away from the threaded component, and one end of the inclined partition is attached to the side wall of the gasifier body.

[0011] As a further embodiment of the present invention, an upper limit rod is fixedly installed on the upper surface of the mounting plate, the upper limit rod being slidably connected to the threaded component, and a lower limit rod is fixedly installed on the lower surface of the mounting plate, the lower limit rod being slidably connected to the upper connecting plate.

[0012] As a further embodiment of the present invention, a feeding component is fixedly installed at the upper end of the gasifier body, a control component is fixedly installed at the upper end of the feeding component, an output pipe is fixedly installed at the upper end of the gasifier body, and multiple burners are fixedly installed in the gasifier body at positions corresponding to the position above the mounting plate and below the upper cleaning component.

The rotation of the threaded rod interacts with the threads on the upper connecting plate, thereby driving the upper connecting plate to move up and down. During the movement of the upper connecting plate, the upper and lower actuating rods rotate, causing them to continuously expand and contract. Through the continuous expansion and contraction of the upper and lower actuating rods, the accumulated ash at the ash outlet is constantly disturbed, allowing the ash to flow out quickly from the ash outlet, increasing the speed at which the ash flows out of the ash outlet, avoiding ash blockage at the ash outlet, and improving the efficiency of ash cleaning and discharge.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-9 This invention provides a technical solution: a gasification furnace for easy ash removal, comprising a furnace body 1, an mounting plate 31 fixedly installed inside the furnace body 1, a threaded rod 5 rotatably installed inside the mounting plate 31, a lower connecting plate 12 rotatably installed at the lower end of the threaded rod 5, an upper connecting plate 13 threadedly connected to the threaded rod 5 at positions corresponding to the upper position above the lower connecting plate 12 and the lower position below the mounting plate 31, multiple connecting seats 29 fixedly installed on both the upper connecting plate 13 and the lower connecting plate 12, a rotating shaft 30 rotatably installed inside the connecting seat 29, and a fixed... An upper actuating rod 15 is installed, and a lower actuating rod 14 is fixedly installed on the lower rotating shaft 30. The upper end of the lower actuating rod 14 is rotatably connected to the lower end of the upper actuating rod 15. An ash outlet 6 is fixedly installed at the lower end of the gasifier body 1. An inner rotating ring 17 is rotatably installed above the ash outlet 6 inside the gasifier body 1. The inner rotating ring 17 is equipped with a lower cleaning component. An upper cleaning component is installed at the upper end of the threaded rod 5. The upper and lower cleaning components can clean the ash outlet 6 and the inner wall surface of the gasifier body 1 while driving the upper connecting plate 13 to move up and down.

[0029] The gas-fired combustion gasifier of the present invention, which facilitates ash removal, has a seepage plate between the ash outlet 6 and the gasifier body 1. The seepage plate allows ash to pass through. The ash generated during combustion in this device flows out from the ash outlet 6 at the lower end. During the ash outflow process, the threaded rod 5 rotates in the forward direction. The rotation of the threaded rod 5 interacts with the thread on the upper connecting plate 13, causing the upper connecting plate 13 to move down closer to the lower connecting plate 12. This drives the upper actuating rod 15 and the lower actuating rod 14 to rotate, thereby causing the middle position of the upper actuating plate and the lower actuating rod 14 to expand outward. The threaded rod 5 rotates in the reverse direction, and the rotation of the threaded rod 5 drives the upper connecting plate 12 to rotate. 3. Moving upwards, the upper connecting plate 13 moves away from the lower connecting plate 12, causing the upper actuating rod 15 and the lower actuating rod 14 to rotate in opposite directions. This causes the connection between the upper actuating rod 15 and the lower actuating rod 14 to contract towards the center. Through the continuous forward and reverse rotation of the threaded rod 5, the upper actuating rod 15 and the lower actuating rod 14 are continuously expanded and contracted. The continuous expansion and contraction of the upper actuating rod 15 and the lower actuating rod 14 continuously disturbs the dust accumulated at the ash outlet 6, allowing the dust to flow out of the ash outlet 6 quickly, increasing the speed at which the dust flows out of the ash outlet 6, avoiding dust blockage at the ash outlet 6, and improving the efficiency of dust cleaning and discharge.

[0030] The ash produced by combustion flows out from the ash outlet 6 at the lower end. During the ash outflow process, the threaded rod 5 rotates in both directions. The rotation of the threaded rod 5 interacts with the threads on the upper connecting plate 13, thereby driving the upper connecting plate 13 to move up and down. During the movement of the upper connecting plate 13, the upper actuating rod 15 and the lower actuating rod 14 rotate, causing the upper actuating rod 15 and the lower actuating rod 14 to continuously expand and contract. Through the continuous expansion and contraction of the upper actuating rod 15 and the lower actuating rod 14, the accumulated ash at the ash outlet 6 is constantly disturbed, so that the ash can flow out from the ash outlet 6 quickly, increasing the speed at which the ash flows out from the ash outlet 6, avoiding ash blockage at the ash outlet 6, and improving the efficiency of ash cleaning and discharge.

[0031] As a further embodiment of the present invention, the lower cleaning assembly includes a protective cover 16 and a connecting shaft 24. The protective cover 16 wraps around the surface of the inner rotating ring 17. The connecting shaft 24 is rotatably mounted on the inner rotating ring 17. A driven gear 22 is fixedly mounted on the connecting shaft 24. A grinding roller 11 is fixedly mounted at the end of the connecting shaft 24 away from the inner rotating ring 17. The surface of the grinding roller 11 is attached to the inner wall of the dust outlet 6. A lower tooth 21 is fixedly mounted at the lower end of the protective cover 16. The lower tooth 21 meshes with the driven gear 22. An output shaft 19 is rotatably mounted inside the protective cover 16. A driving gear 20 is fixedly mounted on the output shaft 19. An internal tooth 18 is fixedly mounted on the surface of the inner rotating ring 17. The internal tooth 18 meshes with the driving gear 20. A rotating motor is fixedly mounted inside the protective cover 16. The output end of the rotating motor is fixedly connected to the output shaft 19.

[0032] During operation, the rotating motor drives the output shaft 19 to rotate (the rotation of the output shaft 19 drives the drive wheel 34 to rotate, the rotation of the drive wheel 34 drives the driven wheel 32 to rotate through the transmission belt 33, and the rotation of the driven wheel 32 drives the threaded rod 5 to rotate). The rotation of the output shaft 19 drives the drive gear 20 to rotate. The rotation of the drive gear 20 interacts with the internal gear 18, thereby driving the inner rotating ring 17 to rotate. The rotation of the inner rotating ring 17 drives the grinding roller 11 on it to rotate. The grinding roller 11 rotates with the inner rotating ring 17, thereby causing the driven gear on the grinding roller 11 to rotate. The interaction between the lower tooth 22 and the lower tooth 21 drives the driven gear 22 to rotate. The rotation of the driven gear 22 drives the connecting shaft 24 to rotate. The rotation of the connecting shaft 24 drives the grinding roller 11 to rotate, so that the inner rotating ring 17 drives the rotating grinding roller 11 to slide across the inner wall surface of the dust outlet 6. This allows the grinding roller 11 to clean the inner wall surface of the dust outlet 6. By rotating the grinding blocks on the surface of the grinding roller 11, the dust adhering to the inner wall of the dust outlet 6 is cleaned, preventing dust from adhering to the inner wall of the dust outlet 6 and causing blockage of the dust outlet 6, thus ensuring the unobstructed flow at the bottom of the dust outlet 6.

[0033] The upper end of the output shaft 19 extends through the protective cover 16 to the mounting plate 31. The output shaft 19 is rotatably connected to the mounting plate 31. A drive wheel 34 is fixedly mounted on the upper end of the output shaft 19, and a driven wheel 32 is fixedly mounted on the threaded rod 5. A transmission belt 33 is sleeved between the driven wheel 32 and the drive wheel 34. The rotation of the output shaft drives the drive wheel to rotate, and the rotation of the drive wheel drives the driven wheel to rotate through the transmission belt. The rotation of the driven wheel drives the threaded rod to rotate.

[0034] As a further embodiment of the present invention, the upper cleaning component includes a threaded part 27, which is threadedly connected to the threaded rod 5. A plurality of connecting plates 25 are fixedly installed on the outer surface of the threaded part 27. An inclined partition 8 is fixedly installed on one end of the connecting plate 25 away from the threaded part 27. One end of the inclined partition 8 is attached to the side wall of the gasifier body 1.

[0035] As a further embodiment of the present invention, a spray pipe 9 is fixedly installed on the connecting plate 25. A rotating nozzle 10 is rotatably installed at one end of the spray pipe 9 near the side wall of the gasifier body 1. A connecting hose 26 is fixedly installed at the lower end of the spray pipe 9. The end of the connecting hose 26 away from the spray pipe 9 is fixedly connected to the threaded part 27.

[0036] When cleaning is required during combustion, the threaded rod 5 rotates in both directions, interacting with the threads on the threaded part 27, thereby driving the threaded part 27 to move up and down. The up and down movement of the threaded part 27 drives the inclined baffle 8 to move up and down through the connecting plate 25, causing the end of the inclined baffle 8 to move up and down continuously. The movement of the inclined baffle 8 cleans and scrapes the inner wall surface of the gasifier body 1. During the scraping and cleaning process after combustion, while the inclined baffle 8 moves up and down, internal water is introduced into the threaded part 27 (a water guide pipe is provided at the lower end of the threaded part 27, and the lower end of the water guide pipe extends to the outside of the gasifier body 1 and connects to the water tank). The water enters the spray pipe 9 through the connecting hose 26. The rotating nozzle 10 at the front end of the spray pipe 9 rotates, spraying the water evenly. The water is sprayed onto the inner wall of the gasifier body 1. The rotating nozzle 10 rotates the sprayer to ensure even and comprehensive water spraying. After the water is sprayed onto the inner wall of the gasifier body 1, it combines with the dust, ensuring that the dust can be completely removed from the inner wall of the gasifier body 1. This avoids the dust from being scraped off due to insufficient gravity, preventing the dust from being re-adhered to the inner wall of the gasifier after being scraped off. As a result, the dust on the inner wall of the gasifier body 1 can be thoroughly cleaned, avoiding the time-consuming problem of manual cleaning, improving cleaning efficiency and quality, reducing dirt on the inner wall of the gasifier body 1, preventing the dirt on the inner wall of the gasifier body 1 from interfering with the processed products, and improving the service life and processing strength of the gasifier.

[0037] In this invention, the rotation of the grinding roller 11 and the up-and-down movement of the inclined baffle 8 are improved. The driven gear 22 rotates, driving the connecting shaft 24 to rotate, which in turn drives the grinding roller 11 to rotate. This causes the inner rotating ring 17 to drive the rotating grinding roller 11 to pass over the inner wall surface of the ash outlet 6, cleaning the inner wall surface of the ash outlet 6. The grinding blocks on the surface of the rotating grinding roller 11 clean the dust adhering to the inner wall of the ash outlet 6, preventing dust from adhering to the inner wall of the ash outlet 6 and causing blockage, thus ensuring unobstructed flow at the bottom of the ash outlet 6. The up-and-down movement of the threaded part 27 drives the inclined baffle 8 to move up and down through the connecting plate 25, causing the end of the inclined baffle 8 to move up and down continuously. The movement of the inclined baffle 8 cleans and scrapes the inner wall surface of the gasifier body 1. After combustion, the scraping... During the cleaning process, while the inclined baffle 8 moves up and down, water is evenly sprayed onto the inner wall of the gasifier body 1. The rotating nozzle 10 rotates to spray, ensuring that the water is sprayed evenly and comprehensively. After the water is sprayed onto the inner wall of the gasifier body 1, it combines with the dust, ensuring that the dust can be completely peeled off from the inner wall of the gasifier body 1. This avoids the dust being too heavy after scraping and re-adhering to the inner wall of the gasifier after being scraped. As a result, the dust on the inner wall of the gasifier body 1 can be thoroughly cleaned, avoiding the time-consuming problem of manual cleaning, improving cleaning efficiency and quality, reducing dirt on the inner wall of the gasifier body 1, preventing the dirt on the inner wall of the gasifier body 1 from interfering with the processed products, and improving the service life and processing strength of the gasifier.

[0038] As a further embodiment of the present invention, an upper limit rod 42 is fixedly installed on the upper surface of the mounting plate 31, and the upper limit rod 42 is slidably connected to the threaded part 27. A lower limit rod 28 is fixedly installed on the lower surface of the mounting plate 31, and the lower limit rod 28 is slidably connected to the upper connecting plate 13.

[0039] As a further embodiment of the present invention, a feed component 2 is fixedly installed at the upper end of the gasifier body 1, a control component 4 is fixedly installed at the upper end of the feed component 2, an output pipe 3 is fixedly installed at the upper end of the gasifier body 1, and multiple burners 7 are fixedly installed inside the gasifier body 1 at positions corresponding to the position above the mounting plate 31 and below the upper cleaning component.

[0040] As a further embodiment of the present invention, the control component 4 is provided with a movable groove 36, which matches the upper end of the feed component 2. A gear ring 38 is rotatably installed in the movable groove 36. A lower limit seat 40 is fixedly installed on the control component 4 at a position corresponding to the movable groove 36. An upper limit seat 41 is fixedly installed above the lower limit seat 40. A plurality of movable partitions 35 are rotatably installed between the upper limit seat 41 and the lower limit seat 40. A connector 39 is rotatably installed at one end of the movable partition 35. The end of the connector 39 away from the movable partition 35 is rotatably connected to the gear ring 38. An extension shaft 37 is rotatably installed inside the control component 4. A side gear 23 is fixedly installed on the extension shaft 37. The side gear 23 meshes with the gear ring 38. One end of the extension shaft 37 extends outside the control component 4.

[0041] In operation, the fuel is added into the gasifier body 1 from the control component 4. During the fuel addition process, the extension shaft 37 rotates, which drives the side gear 23 to rotate. The side gear 23 rotates, which drives the gear ring 38 to rotate. The gear ring 38 rotates, which drives the connecting component 39 to rotate. The connecting component 39 pulls the movable partition 35 between the upper limit seat 41 and the lower limit seat 40, thereby controlling the rotation angle of the movable partition 35, and thus controlling the opening amount of the movable groove 36 in the control component 4, thereby controlling the inflow speed of the fuel.
