Description

Technical Field

[0001] This utility model belongs to the technical field of boiler slag removal machines, and specifically relates to an environmentally friendly scraper-type boiler slag removal machine. Background Technology

[0002] Thermal power companies often use boilers to process industrial solid waste and agricultural and forestry biomass, and the process can also generate electricity using steam. After combustion, the slag naturally settles at the bottom of the boiler and falls through the bottom slag discharge pipe into the slag remover for discharge. The slag remover is a boiler slag removal device. The char slag produced after coal combustion in the boiler is pushed by the grate to the slag pit and then dragged out of the furnace by the slag remover to clear the slag accumulation.

[0003] Chinese patent CN220541113U discloses a boiler ash removal machine that facilitates ash removal. The machine includes a body, drive wheels at both ends, and guide wheels in the middle. A transmission chain is provided around the drive wheels and guide wheels, and evenly distributed scrapers are provided on the transmission chain. The scrapers are characterized by vertically arranged guide grooves at both ends, with sliders within the guide grooves. A fixing ring corresponding to the scraper is provided outside the slider, and climbing wheels are provided at both ends of the fixing ring. The sidewalls of the body are provided with wall panels, and the wall panels have wheel grooves corresponding to the climbing wheels.

[0004] During the slag removal process of the scraper slag remover, the slag first falls into the water tank and is then transported to the outside by the movement of the scraper. Impurities easily accumulate on the surface of the scraper, affecting the cleaning effect of the scraper on the slag and resulting in poor slag removal. In the above document, the scraper cleans the surface of the scraper by the cooperation of the climbing wheel and the wheel groove. However, the scraper surface is provided with guide grooves. If the slag enters the guide grooves, it will obstruct the movement of the scraper, causing the scraper to be unable to clean the scraper properly.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes an environmentally friendly scraper boiler slag discharge machine to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is an environmentally friendly scraper boiler slag remover, including a shell, a rotating component is arranged inside the shell, a telescopic component is fixedly connected to the outer surface of the rotating component, a slag scraping component is fixedly connected to the outer surface of the telescopic component, and a support component is fixedly connected to the outer surface of the shell. The rotating component is used to drive the telescopic component to move, the telescopic component is used to push the slag, and the slag scraping component is used to scrape off the slag adhering to the surface of the telescopic component.

[0009] Furthermore, the rotary assembly includes a motor, a rotating shaft is fixedly connected to the output shaft of the motor, a wheel is fixedly connected to the outer surface of the rotating shaft, a conveyor belt is fixedly installed on the outer surface of the wheel, the rotating shaft is rotatably connected inside the housing, and the motor is located outside the housing.

[0010] Furthermore, the telescopic assembly includes a fixed plate, which is fixedly connected to the outer surface of the conveyor belt. A limit plate is fixedly connected to the outer surface of the fixed plate. A spring is fixedly connected to the top of the fixed plate. A sliding plate is slidably connected to the outer surface of the fixed plate. The sliding plate is fixedly connected to the spring. The limit plate is slidably connected inside the sliding plate.

[0011] Furthermore, the slag scraping assembly includes a connecting rod, which is fixedly connected to a fixed plate. A fixed rod is fixedly connected to the end of the connecting rod, and the fixed rod is slidably connected to a sliding plate. The fixed rod is located on the outer surface of the sliding plate.

[0012] Furthermore, the support assembly includes a connecting plate, the outer surface of which is threaded with bolts, the connecting plate is fixedly connected to the housing by bolts, a support column is fixedly connected to the outer surface of the connecting plate, and a square plate is fixedly connected to the lower end of the support column.

[0013] Furthermore, a protective cover is fixedly connected to the outer surface of the housing, the motor is fixedly installed inside the protective cover, and a cover plate is fixedly connected to the outer surface of the protective cover.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model connects the telescopic component and the slag scraping component. The slag scraping component is located outside the telescopic component. When relative sliding occurs between the telescopic component and the slag scraping component, the slag scraping component blocks the slag on the telescopic component, causing the slag to separate from the telescopic component. The outer surface of the telescopic component does not have grooves, which can prevent slag from entering the telescopic component and affecting its normal sliding.

[0017] 2. This utility model uses the connection between the spring and the sliding plate. When the sliding plate rotates to a position close to the inner wall of the shell, the shell squeezes the sliding plate to compress the spring. The spring generates a counter-force to push the sliding plate, so that the sliding plate abuts against the inner wall of the shell. This allows the sliding plate to better push the slag inside the shell to move, preventing the slag from passing through the gap between the sliding plate and the shell.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-7 As shown, this utility model is an environmentally friendly scraper boiler slag remover, including a shell 1. A rotating component 2 is arranged inside the shell 1. A telescopic component 3 is fixedly connected to the outer surface of the rotating component 2. A slag scraping component 4 is fixedly connected to the outer surface of the telescopic component 3. A support component 5 is fixedly connected to the outer surface of the shell 1. The rotating component 2 is used to drive the telescopic component 3 to move. The telescopic component 3 is used to push the slag. The slag scraping component 4 is used to scrape off the slag adhering to the surface of the telescopic component 3.

[0032] Water is injected into the shell 1, and the boiler slag falls into the shell 1 for cooling. The rotating component 2 is started, which drives the telescopic component 3 to move inside the shell 1. The support component 5 keeps the shell 1 stable. During the movement, the telescopic component 3 is compressed and pushes the cooled slag to move. For environmental protection reasons, the telescopic component 3 pushes the slag to rise gradually. The water on the slag falls back into the shell 1 under the action of gravity and is reused to continue cooling the subsequent slag. After the telescopic component 3 pushes the slag out of the discharge port on the shell 1, the shell 1 no longer squeezes the telescopic component 3. At this time, the telescopic component 3 resets and slides relative to the slag scraping component 4, so that the slag adhering to the telescopic component 3 is scraped off by the slag scraping component 4, avoiding the problem of too much slag adhering to the telescopic component 3 affecting normal slag discharge.

[0033] This utility model connects the telescopic component 3 and the slag scraping component 4. The slag scraping component 4 is located outside the telescopic component 3. When relative sliding occurs between the telescopic component 3 and the slag scraping component 4, the slag scraping component 4 blocks the slag on the telescopic component 3, so that the slag is separated from the telescopic component 3. The outer surface of the telescopic component 3 is not provided with grooves, which can prevent slag from entering the telescopic component 3 and affecting its normal sliding.

[0034] In one embodiment, the rotary assembly 2 includes a motor 201, a rotating shaft 202 fixedly connected to the output shaft of the motor 201, a rotating wheel 203 fixedly connected to the outer surface of the rotating shaft 202, a conveyor belt 204 fixedly mounted on the outer surface of the rotating wheel 203, the rotating shaft 202 being rotatably connected inside the housing 1, and the motor 201 being located outside the housing 1.

[0035] When the motor 201 is started, the output shaft of the motor 201 drives the rotating shaft 202 to rotate, the rotating shaft 202 drives the rotating wheel 203 to rotate, and the rotating wheel 203 drives the conveyor belt 204 to move, so that the conveyor belt 204 rotates inside the housing 1. Cooling water is injected into the housing 1, and the slag falls into the housing 1 and is cooled by the cooling water inside the housing 1. The motor 201 is located on the outside of the housing 1 to prevent the cooling water in the housing 1 from entering the motor 201.

[0036] In one embodiment, the telescopic component 3 includes a fixed plate 301, which is fixedly connected to the outer surface of the conveyor belt 204. A limiting plate 302 is fixedly connected to the outer surface of the fixed plate 301. A spring 303 is fixedly connected to the top of the fixed plate 301. A sliding plate 304 is slidably connected to the outer surface of the fixed plate 301. The sliding plate 304 is fixedly connected to the spring 303. The limiting plate 302 is slidably connected inside the sliding plate 304.

[0037] The conveyor belt 204 drives the fixed plate 301 to move. When the fixed plate 301 rotates to the side near the bottom of the shell 1, the shell 1 squeezes the sliding plate 304. The sliding plate 304 slides on the fixed plate 301, causing the sliding plate 304 to compress the spring 303. The spring 303 generates a counter-force to push the sliding plate 304 into contact with the inner wall of the shell 1. The fixed plate 301 drives the sliding plate 304 to move, which in turn pushes the slag in the shell 1 to move. As the sliding plate 304 gradually rises, the water on the slag falls back into the shell 1 under the action of gravity and can be reused. When the sliding plate 304 pushes the slag to the discharge port on the shell 1, the shell 1 no longer squeezes the sliding plate 304. The spring 303 pushes the sliding plate 304 to reset. The limiting plate 302 limits the movement distance of the sliding plate 304. The slag brought on by the sliding plate 304 is discharged from the discharge port of the shell 1.

[0038] In one embodiment, the slag scraping assembly 4 includes a connecting rod 401, which is fixedly connected to a fixing plate 301. A fixing rod 402 is fixedly connected to the end of the connecting rod 401. The fixing rod 402 is slidably connected to a sliding plate 304 and is located on the outer surface of the sliding plate 304.

[0039] When the sliding plate 304 moves on the fixed plate 301, the fixed rod 402 and the connecting rod 401 remain stationary. The sliding plate 304 and the fixed rod 402 slide relative to each other, and the fixed rod 402 is in close contact with the sliding plate 304. The slag adhering to the sliding plate 304 is blocked by the fixed rod 402, so that the slag is separated from the sliding plate 304, thus cleaning the sliding plate 304.

[0040] In one embodiment, the support component 5 includes a connecting plate 501, the outer surface of which is threaded with bolts 502, the connecting plate 501 is fixedly connected to the housing 1 by bolts 502, the outer surface of the connecting plate 501 is fixedly connected with a support column 503, and the lower end of the support column 503 is fixedly connected with a square plate 504.

[0041] The support column 503 is located below the higher side of the housing 1. The support column 503 is fixed by the connecting plate 501 and bolts 502, which facilitates the installation of the support column 503. The square plate 504 at the bottom of the support column 503 can increase the grounding area, making the support more solid and preventing the housing 1 from tilting or shaking.

[0042] In one embodiment, for the housing 1, a protective cover 6 is fixedly connected to the outer surface of the housing 1, the motor 201 is fixedly installed inside the protective cover 6, and a cover plate 7 is fixedly connected to the outer surface of the protective cover 6.

[0043] The protective cover 6 can protect the motor 201 and prevent it from being damaged by external factors. At the same time, the protective cover 6 also provides a fixed position for the motor 201 to be installed, preventing the motor 201 from being suspended in the air, so that the motor 201 can remain stable during operation and avoid accidental shaking.

[0044] In one embodiment, for the housing 1, an arc plate 8 is fixedly connected inside the housing 1, and the conveyor belt 204 is slidably connected to the arc plate 8.

[0045] The arc plate 8 can tighten the conveyor belt 204 and change the direction of the conveyor belt 204. The arc-shaped design of the arc plate 8 can also prevent the sharp angle from tearing the conveyor belt 204.

[0046] Through the above technical solutions, 1. By connecting the telescopic component 3 and the slag scraping component 4, the slag scraping component 4 is located outside the telescopic component 3. When relative sliding occurs between the telescopic component 3 and the slag scraping component 4, the slag scraping component 4 blocks the slag on the telescopic component 3, causing the slag to separate from the telescopic component 3. The outer surface of the telescopic component 3 is not provided with grooves, which can prevent slag from entering the telescopic component 3 and affecting its normal sliding; 2. By connecting the spring 303 and the sliding plate 304, when the sliding plate 304 rotates to a position close to the inner wall of the housing 1, the housing 1 squeezes the sliding plate 304 to compress the spring 303. The spring 303 generates a counter-force to push the sliding plate 304, so that the sliding plate 304 abuts against the inner wall of the housing 1, thereby allowing the sliding plate 304 to better push the slag in the housing 1 to move, and preventing the slag from passing through the gap between the sliding plate 304 and the housing 1.
