Description

Technical Field

[0001] The utility model relates to a gasifier burner, in particular to a gasifier burner for enhancing mixing, and belongs to the technical field of gasifier burners. Background Technique

[0002] Coal gasification is one of the main ways to cleanly and efficiently utilize coal, and the gasifier is a key equipment in the coal gasification system. Gasifiers can be roughly divided into three different types: fixed bed, fluidized bed, and entrained flow bed. The burner is an indispensable part in the operation of the gasifier. The gas in the gasifier is ejected through the burner to form a flame. The impurities attached to the inner wall of the burner will change the surface roughness of the inner wall of the burner, increase the resistance of gas flow, and thus affect the enhancement of mixing.

[0003] A gasifier burner for enhancing mixing disclosed in the Chinese Patent Publication Specification CN213895736U can repeatedly impact the sundries adsorbed on the inner wall of the pipeline at a higher frequency by means of a cylinder. When the sundries are scraped off by the scraper, water is passed through the intake pipe. At this time, the water flow will carry out the sundries. The whole structure solves the problem that a large amount of straw waste combustion products will adhere to the inner wall of the pipeline during the long-term use of the burner.

[0004] The above device cleans the sundries attached to the inner wall of the pipeline through a scraper with a fixed size. It is found in actual application that when the output end of the burner is conical, it is not convenient to scrape off the sundries attached to the conical area by a scraper with a fixed size. Therefore, we provide a gasifier burner for enhancing mixing. Content of the Utility Model

[0005] The utility model provides a gasifier burner for enhancing mixing, which can scrape off the sundries attached to the conical area of the burner.

[0006] The utility model is realized by the following technical solutions: it includes a pipeline, one end of the pipeline is communicated with an intake pipe, and a cleaning mechanism for cleaning the sundries on the inner wall of the pipeline is arranged at the output end of the pipeline.

[0007] The cleaning mechanism includes a fixing ring fixed on the side of the pipeline by bolts, a fixing rod is fixed on the side of the fixing ring, a connecting plate is fixed at the other end of the fixing rod, a push rod is slidably connected to the side of the connecting plate, a moving plate is fixed at the end of the push rod close to the pipeline, a first installation groove is opened on the circumferential side of the moving plate, a guiding rod is fixed in the first installation groove, a first compression spring is fixed at the other end of the guiding rod, an arc-shaped plate is fixed at the other end of the first compression spring, and a sliding sleeve sleeved on the side of the guiding rod is fixed on the side of the arc-shaped plate close to the guiding rod.

[0008] Specifically, a second installation groove is further formed on the circumferential side surface of the moving plate. A support rod is fixed to one side surface of the arc-shaped plate close to the second installation groove. The support rod is slidably connected to the moving plate through the second installation groove.

[0009] Specifically, two symmetrically arranged first scraping plates are fixed to the circumferential side surface of the arc-shaped plate, and two symmetrically arranged second scraping plates are fixed to the circumferential side surface of the moving plate.

[0010] Furthermore, a guiding block is fixed to one side surface of the connecting plate close to the moving plate. The guiding block is slidably connected to the push rod.

[0011] Specifically, a handle is fixed to one end of the push rod away from the moving plate, and anti-slip lines are formed on the side surface of the handle.

[0012] Furthermore, a limiting mechanism for limiting the push rod is arranged on one side of the connecting plate. The limiting mechanism includes a mounting seat fixed to the side surface of the connecting plate. A limiting hole is formed on the side surface of the push rod. A sliding rod is slidably connected to the mounting seat. An installation ring is fixed to the side surface of the sliding rod. A second compression spring is fixed to one side of the installation ring away from the push rod.

[0014] The utility model provides a gasifier burner for enhancing mixing, and the beneficial effects thereof are as follows:

[0015] 1. For the gasifier burner for enhancing mixing, the push rod can drive the moving plate to move inside the pipeline.

That is, through the cooperation of the arc-shaped plate and the first scraping plate, the tapered area of the pipeline can always be abutted against. By continuously pulling and rotating the push rod, the sundries attached to the tapered area of the pipeline can be scraped off. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] 4. Air inlet pipe Detailed implementation manners

[0028] Please refer to Figures 1 to 6 , an embodiment of the present utility model provides a gasifier burner for enhancing mixing, including a pipeline 1. One end of the pipeline 1 is communicated with an air inlet pipe 4. A cleaning mechanism 2 for cleaning sundries on the inner wall of the pipeline 1 is arranged at the output end of the pipeline 1. The cleaning mechanism 2 includes a fixed ring 201 fixed to the side of the pipeline 1 by bolts, which is convenient for disassembly when not in use. A fixed rod 202 is fixed to the side of the fixed ring 201. The other end of the fixed rod 202 is fixed to a connecting plate 203. A guide block 215 is fixed to the side of the connecting plate 203 close to the moving plate 205. The guide block 215 is slidably connected with a push rod 204. The guide block 215 can guide the push rod 204. A handle 216 is fixed to the end of the push rod 204 away from the moving plate 205. The handle 216 is provided for facilitating the rotation of the push rod 204. Anti-slip lines are provided on the side of the handle 216. The anti-slip lines can increase the friction between the user's hand and the handle 216. The push rod 204 is slidably connected to the side of the connecting plate 203. A moving plate 205 is fixed to the end of the push rod 204 close to the pipeline 1.

[0029] Please refer specifically to Figure 1 and Figure 6, a limiting mechanism 3 for limiting the push rod 204 is arranged on one side of the connecting plate 203. The limiting mechanism 3 includes a mounting seat 301 fixed on the side surface of the connecting plate 203. A limiting hole 305 is formed in the side surface of the push rod 204. A sliding rod 302 is slidably connected to the mounting seat 301. The diameter of the sliding rod 302 is smaller than the inner diameter of the limiting hole 305. An installation ring 303 is fixed on the side surface of the sliding rod 302. A second compression spring 304 is fixed on the side of the installation ring 303 away from the push rod 204. A pull ring 306 is fixed at one end of the sliding rod 302 away from the push rod 204. The outer contour of the pull ring 306 is square.

[0030] The pull ring 306 facilitates pulling the sliding rod 302. The sliding rod 302 can cooperate with the limiting hole 305 to limit the push rod 204, avoiding the push rod 204 from shaking when not in use. When the sliding rod 302 is pulled, it will squeeze the second compression spring 304 through the installation ring 303 until the sliding rod 302 moves out of the limiting hole 305.

[0031] A first installation groove 206 is formed in the circumferential side surface of the moving plate 205. A guide rod 207 is fixed in the first installation groove 206. The other end of the guide rod 207 is fixed with a first compression spring 208. The other end of the first compression spring 208 is fixed with an arc-shaped plate 210. A sliding cylinder 209 slidably sleeved on the side surface of the guide rod 207 is fixed on the side of the arc-shaped plate 210 close to the guide rod 207. A second installation groove 211 is also formed in the circumferential side surface of the moving plate 205. A support rod 212 is fixed on the side surface of the arc-shaped plate 210 close to the second installation groove 211. The support rod 212 is slidably connected to the moving plate 205 through the second installation groove 211. Two symmetric first scraping plates 213 are fixed on the circumferential side surface of the arc-shaped plate 210. Two symmetric second scraping plates 214 are fixed on the circumferential side surface of the moving plate 205.

[0032] Please refer specifically to Figure 3 and Figure 5 , the first compression spring 208 is in a compressed state. The elastic force generated by the deformation of the first compression spring 208 will push the arc-shaped plate 210, so that the arc-shaped plate 210 drives the first scraping plate 213 to abut against the inner wall of the pipeline 1. When the push rod 204 drives the moving plate 205 to move, under the push of the elastic force generated by the deformation of the first compression spring 208, the arc-shaped plate 210 can always fit the inner wall of the pipeline 1, and then the sundries attached to the conical area of the pipeline 1 are scraped off by the first scraping plate 213, effectively improving the cleaning effect.

[0033] Working principle: First, fix the fixing ring 201 on the side of the pipeline 1 through bolts. Pull the sliding rod 302 through the pull ring 306 to release the limit of the sliding rod 302 on the push rod 204. Then, the push rod 204 can drive the moving plate 205 to move inside the pipeline 1. Under the action of the elastic force generated by the deformation of the first compression spring 208, the arc-shaped plate 210 and the sliding cylinder 209 will slide on the guide rod 207, so that the arc-shaped plate 210 drives the first scraper 213 to always abut against the inner wall of the pipeline 1, that is, through the cooperation of the arc-shaped plate 210 and the first scraper 213, it can always abut against the conical area of the pipeline 1. By continuously pulling and rotating the push rod 204, the sundries attached to the conical area of the pipeline 1 can be scraped off. Finally, connect the water source through the air inlet pipe 4 to wash the sundries inside the pipeline 1 clean.
