[0026] The following will further elaborate on this application Figure 1-8 with more details.

[0027] An embodiment of this application discloses a silicon carbide burner for an energy-saving kiln.

[0028] The air volume adjustment mechanism 2 includes an annular plate 210. The surface of the annular plate 210 is fixedly connected with movable columns 207. The number of movable columns 207 is several. The surface of the movable column 207 is movably connected with a connecting rod 208. The bottom of the inner cavity of the connecting rod 208 is fixedly connected with a round rod 206. One side of the round rod 206 is fixedly connected with a second rotating column 205. The second rotating column 205 is rotatably connected to the inner cavity of the annular support tube 7. The inner cavity of the second rotating column 205 is fixedly connected with a blade 204. The other end of the blade 204 is fixedly connected with a first rotating column 203. One side of the first rotating column 203 is rotatably connected with an inner column 201.

[0029] Refer to Figure 5 and Figure 7, a chute 211 is provided at the top of the annular plate 210. A positioning block 212 is fixedly connected to the surface of the annular support tube 7. The number of positioning blocks 212 is several. A rotating shaft 214 is fixedly connected to the inner cavity of the positioning block 212.

The short column 215 is movably connected to the inner cavity of the chute 211. Through the setting of the positioning block 212, the rotating shaft 214 and the first rotating column 203 are supported, thereby preventing the wheel body 213 and the rotating shaft 214 from falling. At the same time, through the setting of the short column 215, the annular plate 210 is limited, making the annular plate 210 rotate more stably on the surface of the wheel body 213;

[0030] Referring to Figure 4 and Figure 8 , the positioning mechanism 3 includes a rotating plate 301 and an arc-shaped positioning plate 307.

Through the cooperation of the plug post 303 and the arc-shaped positioning plate 307, the annular plate 210 is fixed and rotated, thereby enabling the operator to more accurately adjust the opening size of the blade 204 and making the operation process more concise;

[0031] Referring to Figure 2 and Figure 8 , a positioning post 302 is fixedly connected to the top of the rotating plate 301.

A hand-pulling post 306 is fixedly connected to the top of the metal block 305. A tension spring 304 is sleeved on the surface of the plug post 303. The top of the tension spring 304 is fixedly connected to the top of the positioning post 302, and the other end of the tension spring 304 is fixedly connected to the bottom of the metal block 305. Through the setting of the tension spring 304, when the tension spring 304 is deformed under force, the plug post 303 is pulled out of the inside of the rotating plate 301, and after restoring the deformation, the plug post 303 can be quickly inserted into the inner cavity of the arc-shaped positioning plate 307, achieving the effect of positioning the rotating plate 301. Also, through the setting of the hand-pulling post 306, a pulling fulcrum is provided for the operator, making it easier to adjust the air volume;

[0032] Referring to Figure 8 , a support column 202 is fixedly connected to the surface of the inner column 201. The other end of the support column 202 is fixedly connected to the inner wall of the annular support tube 7. The number of support columns 202 is four. Through the setting of the support column 202, the rotating plate 301 can be fixed in the inner cavity of the annular support tube 7, thereby being able to support and stabilize the position of the inner column 201;

[0033] Referring toFigure 6 and Figure 5 , a lower fixing ring 4 is fixedly connected to the top of the air inlet pipe 108 and the bottom of the annular support pipe 7. A positioning screw is threadedly connected inside the lower fixing ring 4. An upper external connection ring 6 is fixedly connected to the top of the annular support pipe 7. Through the setting of the lower fixing ring 4, the annular support pipe 7 can be fixed at the desired position, and the lower fixing ring 4 is fixed by bolts, so that the annular support pipe 7 is convenient to disassemble. Also, through the setting of the upper external connection ring 6, external components can be added to the top of the upper external connection ring 6;

[0034] Refer to Figure 6 , an activity groove 209 is opened in the inner cavity of the connecting rod 208. The activity column 207 is slidably connected to the inner cavity of the activity groove 209. A limiting block 216 is fixedly connected to one side of the activity column 207. The limiting block 216 is movably connected to one side of the connecting rod 208. The diameter of the limiting block 216 is larger than the diameter of the activity groove 209. Through the setting of the limiting block 216, the position of the connecting rod 208 is limited to prevent the connecting rod 208 from falling off the surface of the activity column 207 when rotating, thereby improving the stability of the connecting rod 208 when rotating.

[0035] Working principle: When the air intake needs to be adjusted, first pull up the hand-operated column 306. The hand-operated column 306 drives the metal block 305 to move. The movement of the metal block 305 deforms the tension spring 304. The movement of the metal block 305 drives the positioning column 302 to move until it moves out of the inner cavity of the arc-shaped positioning plate 307. Then push the rotating plate 301. The rotating plate 301 rotates inside the protective shell 5. The rotation of the rotating plate 301 drives the annular plate 210 to rotate clockwise on the surface of the short column 215. At the same time, the short column 215 rotates inside the sliding groove 211, thereby limiting the annular plate 210 to make its rotation more stable. The rotation of the annular plate 210 drives the activity column 207 to move. The movement of the activity column 207 drives the connecting rod 208 to rotate counterclockwise. The rotation of the connecting rod 208 drives the second rotating column 205 and the round rod 206 to rotate clockwise. The rotation of the second rotating column 205 drives the blade 204 to rotate. The rotation of the blade 204 drives the first rotating column 203 to rotate, thereby adjusting the air intake. When the ideal air intake is adjusted, release the round rod 206 to make the tension spring 304 restore its deformation, drive the metal block 305 to move downward, and the movement of the metal block 305 drives the plug 303 to move downward until the plug 303 is clamped into the hole opened in the inner cavity of the arc-shaped positioning plate 307.

[0036] The basic principle, main features and advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
