Description

Technical Field

[0001] The utility model relates to the field of pulverized coal burner equipment, in particular to an efficient pulverized coal burner. Background Technique

[0002] A burner is a general term for a device that sprays and mixes fuel and air for combustion; a pulverized coal burner is a device that uses pulverized coal as fuel and, with the assistance of combustion-supporting air, enables the pulverized coal to burn fully in a short time, thereby generating a high-temperature eddy current.

[0003] The burner sprays and burns after mixing pulverized coal with air. When the pulverized coal is mixed with air and transported and sprayed through a pipeline, a part of the pulverized coal will adsorb and fix on the inner side wall of the pipeline. In this way, when used for a long time, the pipeline diameter becomes narrower, reducing the output efficiency. At the same time, the pulverized coal is prone to overheat and explode, having a certain safety hazard. Moreover, after the pulverized coal is mixed with air, the oxygen content in the air is certain, so it is very difficult for the pulverized coal to burn completely. Therefore, there is an urgent need for a device to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an efficient pulverized coal burner to solve the problems put forward in the above background technique.

When in use, the motor is started, the motor drives the gear to rotate, so as to drive the toothed ring to rotate around the outer side of the pipeline main body, and then drive the movable ring to rotate inside the pipeline main body through the connecting rod, so that the cleaning mechanism rotates to clean the inner side wall of the pipeline main body, thereby preventing the pulverized coal from adsorbing on the inner side wall of the pipeline main body.

[0006] Preferably, the injection mechanism includes an extension plate and an injection pipe. The extension plate is fixed on one side of the support ring by bolts, the injection pipe is inlaid and fixed at the center position of the support ring, and the lower end of the injection pipe is inlaid and fixed at the top position of the pipeline main body. When in use, if the oxygen is insufficient, at this time, oxygen is injected into the pipeline main body through an oxygen tank and the injection pipe to increase the oxygen content inside the pipeline main body, so as to ensure that the pulverized coal can burn fully.

[0007] Preferably, the cleaning mechanism includes a hollow block, a scraper, and a spring. The hollow block is fixed to one side of the movable ring. The scraper is slidably disposed inside the hollow block. The spring is fixed between the bottom end of the scraper and the bottom end inside the hollow block. When in use, the elastic force of the spring causes the scraper to closely adhere to the inner sidewall of the pipeline body. Then, when the movable ring rotates, it drives the hollow block to rotate, causing the scraper to rotate accordingly, thus scraping the inner sidewall of the pipeline body.

[0008] Preferably, the lower end of the gear meshes with the toothed ring, and the other side of the connecting rod is fixed to the side position of the toothed ring.

[0012] When the present utility model is in use and there is insufficient oxygen, at this time, oxygen is injected into the pipeline body through the oxygen tank and the injection pipe to increase the oxygen content inside the pipeline body, thereby ensuring that the pulverized coal can burn fully.

[0013] When the present utility model is in use, the motor is started, and the motor drives the gear to rotate, thus driving the toothed ring to rotate around the outer side of the pipeline body. Then, through the connecting rod, the movable ring is driven to rotate inside the pipeline body, causing the cleaning mechanism to rotate. Due to the elastic force of the spring, the scraper closely adheres to the inner sidewall of the pipeline body. Then, when the movable ring rotates, it drives the hollow block to rotate, causing the scraper to rotate accordingly, thus scraping the inner sidewall of the pipeline body, thereby preventing the pulverized coal from adsorbing on the inner sidewall of the pipeline body.

[0018] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , the present invention provides an efficient pulverized coal burner, which includes a pipeline main body 1. A support ring 2 is fixed to the outside of the pipeline main body 1 by bolts. A motor 5 is fixed to the top of the support ring 2 through a mounting frame. There is an injection mechanism on one side of the support ring 2 for facilitating the injection of oxygen. A gear 6 is fixed to the output end of the motor 5 through a coupling. A toothed ring 9 is movably sleeved on the outside of the pipeline main body 1. The lower end of the gear 6 meshes with the toothed ring 9. A movable ring 7 slides inside the pipeline main body 1. One side of the movable ring 7 is welded and fixed with a connecting rod 8. The other side of the connecting rod 8 is welded and fixed to the side position of the toothed ring 9. There is a cleaning mechanism on one side of the movable ring 7 for facilitating the cleaning of the inner wall of the pipeline main body 1. When in use, the motor 5 is started, and the motor 5 drives the gear 6 to rotate, so as to drive the toothed ring 9 to rotate around the outside of the pipeline main body 1, and then drive the movable ring 7 to rotate inside the pipeline main body 1 through the connecting rod 8, so that the cleaning mechanism rotates to clean the inner wall of the pipeline main body 1, thereby preventing pulverized coal from adsorbing on the inner wall of the pipeline main body 1.

[0020] The injection mechanism includes an extension plate 3 and an injection pipe 4. The extension plate 3 is fixed to one side of the support ring 2 by bolts. The injection pipe 4 is embedded and fixed at the center position of the support ring 2. The lower end of the injection pipe 4 is embedded and fixed to the top of the pipeline main body 1 through a one-way valve. The top of the injection pipe 4 is connected to an oxygen tank through a pipeline. When in use, if the oxygen is insufficient, at this time, oxygen is injected into the pipeline main body 1 through the oxygen tank and the injection pipe 4 to increase the oxygen content inside the pipeline main body 1, so as to ensure that the pulverized coal can burn sufficiently.

[0021] The cleaning mechanism includes a hollow block 10, a scraping plate 11 and a spring 12. The hollow block 10 is welded and fixed to one side of the movable ring 7. The scraping plate 11 slides inside the hollow block 10. The spring 12 is welded and fixed between the bottom end of the scraping plate 11 and the bottom end inside the hollow block 10. The outside of the scraping plate 11 is closely attached to the inner wall of the pipeline main body 1, and the spring 12 is in a compressed state. When in use, the elastic force of the spring 12 makes the scraping plate 11 closely attached to the inner wall of the pipeline main body 1. Then when the movable ring 7 rotates, it drives the hollow block 10 to rotate, so that the scraping plate 11 rotates accordingly, thus scraping the inner wall of the pipeline main body 1.

[0022] Working principle: When in use, if there is insufficient oxygen, oxygen is injected into the interior of the pipeline main body 1 through the oxygen tank and the injection pipe 4 at this time to increase the oxygen content inside the pipeline main body 1, so as to ensure that the pulverized coal can burn sufficiently; when in use, the motor 5 is started, the motor 5 drives the gear 6 to rotate, thus driving the toothed ring 9 to rotate around the outside of the pipeline main body 1, and then driving the movable ring 7 to rotate inside the pipeline main body 1 through the connecting rod 8, so that the cleaning mechanism rotates. Due to the elastic force of the spring 12, the scraper 11 is closely attached to the inner side wall of the pipeline main body 1. Then when the movable ring 7 rotates, it drives the hollow block 10 to rotate, so that the scraper 11 follows to rotate, thus scraping the inner side wall of the pipeline main body 1, so as to prevent the pulverized coal from adsorbing on the inner side wall of the pipeline main body 1.
