Description

Technical Field

[0001] This utility model relates to the field of coking removal technology, and in particular to a coking removal device for a kiln head burner. Background Technology

[0002] A kiln head burner is a combustion device used at the kiln head of an industrial kiln. Its main function is to inject fuels such as pulverized coal and natural gas, along with combustion air, into the kiln at a suitable ratio, speed, and angle, so that the fuel can burn efficiently and stably inside the kiln, providing heat for the calcination of materials. However, during the combustion process, the ash particles of these fuels are prone to softening and melting at high temperatures. When the temperature drops, they will adhere to the burner surface and gradually form coke. Coke will form a heat insulation layer on the burner surface, affecting heat transfer and altering the air-fuel mixture inside the burner, resulting in incomplete combustion. Therefore, it is necessary to clean the coke in a timely manner.

[0003] In existing coking removal devices, when the burner is not in operation, a scraper hidden inside the burner extends and contacts the end face of the burner to scrape off the coking. However, for thicker and harder coking, the scraper only makes planar contact with the end face of the burner, and it is difficult to penetrate into the coking to effectively remove it. Therefore, the cleaning efficiency is limited. Based on the above situation, it is necessary to design a kiln head burner coking removal device to solve the above problems. Utility Model Content

[0004] This invention provides a coking cleaning device for kiln head burners, which solves the problem in the prior art that the scraper only scrapes the surface of the burner end face, making it difficult to penetrate deep into the coking and effectively remove it, resulting in limited cleaning efficiency.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] A coking cleaning device for a kiln head burner includes a burner body, a cleaning assembly, and a moving component. The cleaning assembly is used to clean the end face of the burner body. The cleaning assembly includes a support rod disposed inside the burner body and at least two scraping components hinged to the support rod. The scraping component has scraping teeth at the end away from the support rod. The support rod is also provided with an unfolding assembly for controlling the opening and closing of the scraping component. When the scraping component unfolds, the end face of the scraping teeth is flush with the end face of the burner body. The moving component is used to drive the scraping teeth to move towards or away from the end face of the burner body.

[0007] Preferably, the unfolding assembly includes a rotating rod threaded to the outer wall of the support rod, a movable seat rotatably connected to one end of the rotating rod, and an unfolding rod hinged to the movable seat. The other end of the unfolding rod is hinged to the scraper, one end of the rotating rod is rotatably connected to the movable seat, and one end of the support rod is provided with an abutment plate for limiting the scraper.

[0008] Preferably, the movable component is threadedly connected to the inner wall of the burner body and rotatably connected to the rotating rod.

[0009] Preferably, the scraping teeth on at least two of the scrapers are arranged alternately.

[0010] Preferably, the contact plate is used to seal the burner body when it is located inside the burner body.

[0011] Preferably, the support rod, rotating rod, and moving part are all equipped with operating wheels.

[0012] The beneficial effects of this utility model are as follows: the cleaning component is moved out of the burner body by the moving component, and then the unfolding component is unfolded. At this time, the moving component makes the scraping teeth in close contact with the end face of the burner body, and the coking on the end face of the burner is scraped off by rotating the cleaning component. During this process, because the contact area between the scraping teeth and the coking is reduced, it can be effectively scraped off by partially penetrating into the coking, thereby improving the cleaning efficiency.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0021] Reference Figures 1-5 As shown, a coking cleaning device for a kiln head burner includes a burner body 1. During operation, fuel is typically delivered to the burner body 1 via a pneumatic conveying system and then blown into the burner body 1 through a pipeline under the action of compressed air. However, coking occurs in the burner body 1 during fuel combustion. The coke adheres to the end face of the burner body 1, clogging the air holes and fuel nozzles, reducing combustion efficiency and polluting the air. Therefore, a cleaning assembly is provided inside the burner body 1 to clean the end face of the burner body 1. The cleaning assembly includes a support rod 201 located inside the burner body 1 and at least two scraper components 202 hinged to the support rod 201. Scraping teeth 3 are provided at the end of each scraper component 202 away from the support rod 201. The scraping teeth 3 on the at least two scraper components are staggered. During operation, the burner body 1 is stopped, and then a moving component 4 located inside the burner body 1 is moved... The cleaning assembly is moved out of the burner body 1. At this time, the unfolding assembly on the support rod 201 unfolds at least two scraper parts 202. The end face of the unfolded scraper parts 202 is flush with the end face of the burner body 1. Then, the moving part 4 drives the cleaning assembly to move closer to the burner body 1, and makes the scraper teeth 3 tightly abut against the coke. The end face of the scraper teeth 3 can be designed to be pointed. When the scraper teeth 3 abut against the coke, they can effectively penetrate into the coke. Then, the unfolding assembly and the cleaning assembly are rotated to make the scraper parts 202 rotate. The scraper teeth 3 separate the coke on the end face of the burner body 1, reducing the resistance during scraping. The staggered scraper teeth 3 also improve the cleaning efficiency. After use, the moving part 4 controls the scraper teeth 3 to move away from the end face of the burner. Then the unfolding assembly closes the scraper parts 202. At the same time, the moving part 4 moves the whole assembly back into the burner body 1, and then it can be used directly next time.

[0022] Reference Figures 1-5As shown, furthermore, to enable the scraper component 202 to be deployed, the deployment assembly includes a rotating rod 501 threaded to the outer wall of the support rod 201, a movable seat 502 rotatably connected to one end of the rotating rod 501, and a deployment rod 503 hinged to the movable seat 502. The other end of the deployment rod 503 is hinged to the scraper component 202, and one end of the rotating rod 501 is rotatably connected to the movable seat 502. In use, one hand holds the support rod 201 while the other hand rotates the rotating rod 501. At this time, the rotating rod 501 will drive the movable seat 502 to move closer to or further away from the scraper component 202. When the movable seat 502 approaches the scraper 202, the movable seat 502 drives the unfolding rod 503 to abut against the scraper 202, thereby unfolding the scraper 202. At this time, the scraper 202 will abut against the abutting plate 6 set on one end of the support rod 201 to limit the scraper 202. At this time, the end face of the scraper tooth 3 is just flush with the end face of the burner body 1, which facilitates close contact with the end face of the burner body 1. When cleaning the coke, the rotating rod 501 is rotated, and the rotating rod 501 drives the support rod 201 and the scraper 202 to rotate, thereby scraping off the coke on the end face of the burner body 1.

[0023] When the contact plate 6 is located inside the burner body 1, it is used to seal the burner body 1. The contact plate 6 can be made of heat-insulating and fireproof material. When the cleaning component and the unfolding component are stored inside the burner body 1, the contact plate 6 seals the burner body 1. When the burner body 1 is working, it can protect the cleaning component and the unfolding component.

[0024] Reference Figures 1-5 As shown, the movable part 4 is further threaded onto the inner wall of the burner body 1 and rotatably connected to the rotating rod 501. When the cleaning component and the unfolding component are moved out and into the interior of the burner body 1 during use, the movable part 4 rotates inside the burner body 1 and drives the entire component to move. It can also prevent the movable part 4 from moving when the unfolding component and the cleaning component are moving.

[0025] In order to facilitate operation, operating wheels 7 are provided on the support rod 201, the rotating rod 501 and the moving part 4, so that users can easily apply force.
