[0027] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention 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, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] like Figures 1 to 6 As shown, an automatic chimney dust cleaning device in one embodiment of the utility model includes a cylinder 3, which is fixedly mounted on the heat insulation cover on the top of the chimney 2. The cylinder 3 penetrates the heat insulation cover on the top of the chimney 2 and is sealed with the heat insulation cover on the chimney 2. A telescopic rod 31 is provided at the lower end of the cylinder 3, and a first rotating rod 4 is connected to the telescopic rod 31. A cleaning ring 8 is welded at the bottom of the first rotating rod 4. The outer diameter of the cleaning ring 8 matches the inner diameter of the chimney 2. The cylinder 3 is driven, and the telescopic rod 31 is extended and retracted, so that the dust on the inner wall of the chimney 2 can be cleaned. However, this method has a high requirement on the stroke of the cylinder, and it is also impossible to clean the chimney 2 when the kiln 1 is working.

[0029] like Figures 2 to 4 As shown, in order to clean the dust on the inner wall of the chimney 2 when the kiln 1 is working, the front end of the telescopic rod 31 is set as a hollow cylinder, a first bearing 32 is welded on the inner wall of the cylinder, and the first rotating rod 4 is inserted into the first bearing 32 by interference fit.

[0030] Specifically, the rotating outer ring of the first bearing 32 is welded to the inner wall of the telescopic rod 31 , the outer wall of the first rotating rod 4 is inserted into the rotating inner ring of the first bearing 32 , and the first rotating rod 4 rotates in the telescopic rod 31 through the first bearing 32 .

[0031] The second rotating rod 5 is slidably connected inside the first rotating rod 4. A plurality of convex strips 41 are welded on the inner wall of the first rotating rod 4, and a plurality of slideways 51 matching the convex strips 41 are provided on the outer wall of the second rotating rod 5. The convex strips 41 on the first rotating rod 4 are inserted into the slideways 51, so that the second rotating rod 5 can only telescopically slide inside the first rotating rod 4, but cannot rotate inside the first rotating rod 4. When the first rotating rod 4 rotates, the second rotating rod 5 will also rotate along with the first rotating rod 4.

[0032] A plurality of first supporting rods 6 are welded to the first rotating rod 4. A hinge column 61 is provided on one end of the plurality of first supporting rods 6 away from the first rotating rod 4. A second supporting rod 62 is also connected to the hinge column 61. The second supporting rod 62 is hinged to the first supporting rod 6 through the hinge column 61. A cleaning strip 621 is welded to one end of the second supporting rod 62 away from the hinge column 61. The end of the cleaning strip 621 away from the second supporting rod 62 is arc-shaped. A fan blade 9 is welded to the lower end of the second rotating rod 5.

[0033] Specifically, when the kiln 1 is working, under the effect of the chimney, waste gas, dust and other waste materials of the kiln 1 flow to the upper part of the chimney 2 along with the airflow. When the airflow passes through the fan blade 9, the fan blade 9 is blown by the airflow to drive the second rotating rod 5 to rotate, and the second rotating rod 5 drives the first rotating rod 4 to rotate together. When the first rotating rod 4 and the second rotating rod 5 rotate, the second supporting rod 62 hinged to the first supporting rod 6 is straightened under the action of centrifugal force, and the cleaning strip 621 on the second supporting rod 62 will stick to the inner wall of the chimney 2 and rotate on the inner wall of the chimney 2 to clean the inner wall of the chimney 2.

[0034] Specifically, because when the kiln 1 is working, gas will flow out of the chimney 2 through the fan blades 9, so the first rotating rod 4 and the second rotating rod 5 can rotate continuously, and the cleaning strip 621 continuously cleans the inner wall of the chimney 2. At the same time, because the cleaning strip 621 continuously rotates on the inner wall of the chimney 2, the dust generated during sintering is not easy to stay on the inner wall of the chimney 2, and the inner wall of the chimney 2 can be kept clean.

[0035] Furthermore, the first support rod 6 is symmetrically installed on the first rotating rod 4 and the second rotating rod 5, and is staggered. When the fan blades 9 drive the first rotating rod 4 and the second rotating rod 5 to rotate, the cleaning strip 621 is attached to the inner wall of the chimney 2 under the action of centrifugal force. The lower end surface of the upper cleaning strip 621 is flush with the upper end surface of the lower cleaning strip 621, so that no gap is left when cleaning the inner wall of the chimney 2.

[0036] Preferably, the cleaning strip 621 is made of polytetrafluoroethylene, which has a very small friction coefficient and is resistant to acids, alkalis, and various organic solvents, and can ensure that the first rotating rod 4 and the second rotating rod 5 continue to rotate when the cleaning strip 621 cleans the inner wall of the chimney 2. At the same time, polytetrafluoroethylene can withstand temperatures up to 260°C and can be used continuously in a high temperature environment without melting or decomposition.

[0037] When the chimney 2 is used for a long time, tar will gradually accumulate on the inner wall of the chimney 2 near the kiln 1 . Too thick tar will also affect the discharge of airflow in the chimney 2 .

[0038] like Figures 2 to 6 As shown, in order to solve the problem of long-term accumulation of tar on the inner wall of the chimney 2, a sleeve 7 is sleeved on the first rotating rod 4. A second bearing 71 is welded on the outer wall of the sleeve 7, and the rotating inner ring of the second bearing 71 is welded on the outer wall of the sleeve 7. A plurality of connecting plates 711 are welded on the rotating outer ring of the second bearing 71, and a cleaning ring 8 is welded on one end of the connecting plate 711 away from the second bearing 71, and the outer wall of the cleaning ring 8 matches the inner wall of the chimney 2.

[0039] Specifically, the sleeve 7 isolates the second bearing 71 from direct contact with the first rotating rod 4, and the length of the sleeve 7 is more than 3 times the thickness of the second bearing 71, which can enhance the strength of the first rotating rod 4 and protect the first rotating rod 4 from bending under the action of external force.

[0040] Specifically, when the kiln 1 works for a long time and needs to be shut down for maintenance, the cylinder 3 is started, and the telescopic rod 31 extending from the cylinder 3 pushes the first rotating rod 4 to move downward, so that the cleaning ring 8 moves downward, and the tar on the inner wall of the chimney 2 can be cleaned.

[0041] It is worth noting that because the second rotating rod 5 slides inside the first rotating rod 4 and can be retracted into the first rotating rod 4, the kiln 1 will not be damaged. When the cleaning work is completed, the telescopic rod 31 retracts into the cylinder 3, and the second rotating rod 5 extends out of the first rotating rod 4 under the action of gravity, and the fan blade 9 on the second rotating rod 5 can always be kept at the intersection of the kiln 1 and the chimney 2, and there can be enough airflow to drive the fan blade 9 to rotate.

[0042] When in use, the kiln 1 is started, and because the high-temperature airflow moves upward, the airflow mixed with tar and dust flows toward the chimney 2, and after passing through the fan blades 9, it can drive the fan blades 9 to rotate. The fan blades 9 drive the second rotating rod 5 and the first rotating rod 4 to rotate, and the first support rod 6 welded on the first rotating rod 4 will also rotate around the central axis of the first rotating rod 4. The second support rod 62 hinged on the first support rod 6 is thrown up under the action of centrifugal force, so that the cleaning strip 621 on the second support rod 62 can continuously clean the dust on the inner wall of the chimney 2.

[0043] When the furnace is shut down for maintenance, the cylinder 3 is started, and the telescopic rod 31 pushes the first rotating rod 4 to move downward, and the cleaning ring 8 on the first rotating rod 4 can clean the tar at the lower end of the inner wall of the chimney 2. After cleaning, 31 retracts into the cylinder 3, and the second rotating rod 5 can extend into the first rotating rod 4 under the action of gravity, and the fan blades 9 on the second rotating rod 5 can always be kept at the intersection of the kiln 1 and the chimney 2, so that the fan blades 9 can be at the fastest flow rate of the airflow, and the second rotating rod 5 can continue to rotate stably, so that when the second rotating rod 5 drives the first rotating rod 4 to rotate, the cleaning strip 621 installed on the first rotating rod 4 can better clean the inner wall of the chimney 2. At the same time, when dust accumulates on the fan 9 at the intersection of the kiln 1 and the chimney 2, it can also be easily cleaned.

[0044] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
