[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figures 1 to 4 , is the first embodiment of the utility model, which provides a technical solution: an automatic sootblowing device, comprising

[0023] A high-pressure air supply main pipe 1 connected to an external high-pressure air pump and erected above a calcining furnace body 5, a plurality of air supply branch pipes 2 connected to one side of the high-pressure air supply main pipe 1, a solenoid valve 3 installed at the beginning of each air supply branch pipe 2, an end pipe 6 installed at the end of each air supply branch pipe 2, a metal corrugated hose 7 installed at both ends of the end pipe 6, a cover 4 installed on the top surface of the metal corrugated hose 7 and covering the overflow port 52, an oblique hole air blowing pipe 42 installed at the bottom of the cover 4 and inserted into the inner side of the overflow port 52, the end of the metal corrugated hose 7 is connected to the oblique hole air blowing pipe 42 at the bottom of the cover 4, a plurality of air blowing holes inclined downward are opened on the surface of the oblique hole air blowing pipe 42, and the model of the solenoid valve 3 is HYZF2-20;

[0024] The limiting structure 8 includes a cylindrical base 81 welded and fixed on the top surface of the calcining furnace body 5 and located on both sides of the overflow port 52, a cylindrical inner groove 83 opened in the cylindrical base 81, a spring 84 and a cylindrical inner block 85 installed in the cylindrical inner groove 83, a cylindrical pull rod 86 fixed on the top surface of the cylindrical inner block 85 and the top end of which penetrates to the top of the cylindrical base 81, and a limiting pressure plate 82 rotatably sleeved on the top surface of the cylindrical pull rod 86. The end of the limiting pressure plate 82 extends to the top of the mouth cover 4 to press the mouth cover 4, which can stably press and limit the mouth cover 4. Subsequently, the limiting pressure plate 82 only needs to be lifted and rotated away from the top of the mouth cover 4 to release the limit of the mouth cover 4, thereby realizing the rapid disassembly and assembly of the mouth cover 4. A rectangular block 87 is welded and fixed on the bottom surface of the limiting pressure plate 82. An annular groove 88 corresponding to the rectangular block 87 is provided on the top surface, and the rectangular block 87 is inserted into the annular groove 88, so that the limiting pressure plate 82 can be stably pressed on the top of the mouth cover 4 for compression and limiting, to prevent the limiting pressure plate 82 from rotating and moving away from the top of the mouth cover 4 by itself. If the mouth cover 4 needs to be removed for maintenance in the later stage, it is only necessary to lift the limiting pressure plate 82 first, so that the cylindrical pull rod 86 moves up with the cylindrical inner block 85 and compresses the spring 84 until the rectangular block 87 moves out of the annular groove 88. At this time, the end of the limiting pressure plate 82 can be rotated and moved away from the top of the mouth cover 4, and no obstruction or limitation will be caused to the mouth cover 4. At this time, because the metal corrugated hose 7 is a metal hose and can be bent freely, the operator can lift the mouth cover 4 to pull the inclined hole blowing pipe 42 out of the overflow port 52 for maintenance.

[0025] Among them, a ring socket 41 is fixed on the bottom surface of the mouth cover 4, and the ring socket 41 is adapted to the overflow port 52. The ring socket 41 is inserted into the overflow port 52 to ensure the installation stability of the mouth cover 4 and prevent the mouth cover 4 from sliding horizontally after installation.

[0026] The top end of the spring 84 abuts against the top inner wall of the cylindrical inner groove 83 , and the bottom end of the spring 84 abuts against the top surface of the cylindrical inner block 85 .

[0027] A circular rod hole communicating with the cylindrical inner groove 83 is formed on the top surface of the cylindrical base 81 , and the circular rod hole corresponds to the cylindrical pull rod 86 , so that the cylindrical pull rod 86 can pass through smoothly.

[0028] In summary, during actual use, the material in the feed bin 51 will fall into the calcining furnace body 5 for calcining, and ash will accumulate on the inner wall of the overflow port 52 during the calcining process. At this time, the external high-pressure air pump connected to the high-pressure air supply main pipe 1 is started, and the high-pressure airflow will be injected into the high-pressure air supply main pipe 1 first, and then the high-pressure airflow will be transported to each end pipe 6 through the air supply branch pipe 2, and then transported to the inclined hole blowing pipe 42 through the metal corrugated hose 7, and blown out through the blowing holes on the surface of the inclined hole blowing pipe 42 that are inclined downward, so that the ash on the inner wall of the overflow port 52 can be blown away by high-pressure blowing, so that the ash can fall into the calcining furnace body 5 for full combustion.

[0029] Example 2

[0030] See also Figures 1 to 5 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the sealing performance of the cover 4 after installation can be ensured by providing a sealing ring 9.

[0031] Specifically, a sealing ring 9 is sleeved and installed on the surface of the mouth cover 4, and the sealing ring 9 is in contact with the top surface of the calcining furnace body 5. An integrated sealing convex ring 92 is provided on the bottom surface of the sealing ring 9. Both are made of fluororubber and will undergo elastic deformation when squeezed. An annular sealing groove 53 corresponding to the sealing convex ring 92 is provided on the top surface of the calcining furnace body 5 relative to the outside of the overflow port 52. The sealing convex ring 92 is squeezed into the annular sealing groove 53 to ensure the sealing performance of the mouth cover 4 when it is covered on the top of the overflow port 52.

[0032] Among them, the inner wall of the sealing ring 9 is provided with a plurality of integrated T-shaped sockets 91, both of which are made of fluororubber and will undergo elastic deformation when squeezed. The surface of the mouth cover 4 is provided with a plurality of T-shaped slots 43 corresponding to the T-shaped sockets 91, and the T-shaped sockets 91 are embedded in the T-shaped slots 43 to ensure the installation stability of the sealing ring 9.

[0033] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
