Description

Technical Field

[0001] This utility model relates to the field of boiler igniter technology, specifically to a high-temperature resistant ceramic igniter for biomass boilers. Background Technology

[0002] Biomass pellet combustion boilers are a representative type of combustion equipment in the field of renewable energy. The material they burn is pellets made from waste agricultural products. These materials are renewable and very common, making them very environmentally friendly. At the same time, these fuels replace the electricity, oil, or other high-energy-consuming fuels used previously, reducing operating costs and environmental pollution. Before the boiler is ignited, an igniter is required to ignite the fuel.

[0003] In the prior art, Chinese Patent Publication No. CN204678390U discloses an igniter for a biomass fuel boiler, including a fan, an ignition cylinder, and an ignition core. The air outlet of the fan is adapted to connect with the bottom port of the ignition cylinder. The ignition core is fitted onto the top of the ignition cylinder. The ignition cylinder is equipped with an airflow control mechanism installed at the bottom of the ignition cylinder. The ignition core contains an electric heating wire, enabling automatic and rapid ignition without any ignition material, replacing manual ignition, saving labor costs, eliminating safety hazards, and ensuring ignition quality. However, in actual use, the ignition core is only fitted onto the top of the ignition cylinder without a limiting mechanism. This makes it easy for the position of the ignition core to shift, thus affecting the normal operation of the igniter. Utility Model Content

[0014] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Example 1 like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, a high-temperature resistant ceramic igniter for a biomass boiler includes: a blower 1, an ignition tube 5, and a ceramic ignition core 20. The bottom of the blower 1 is fixedly connected to a support foot 2, which has an installation hole. An air outlet pipe 3 is fixedly inserted into the right side of the blower 1. A first flange 4 is fixedly fitted on the outer edge of the air outlet pipe 3. Several bolts 7 are movably inserted into the first flange 4. A second flange 6 is fixedly fitted on both ends of the outer edge of the ignition tube 5. The ceramic ignition core 20 is movably inserted into the right end of the inner cavity of the ignition tube 5. A second through hole 22 and a honeycomb through hole 21 are provided on the ceramic ignition core 20. A threaded rod 23 is movably inserted through the inner cavity of the second through hole 22. A nut 24 is fitted on the outer edge of the threaded rod 23 near the left end.

[0016] In this embodiment, an electric heating wire is installed in the inner cavity of the ceramic ignition core 20. A third flange 25 is provided on the right side of the ignition tube 5. A connecting plate 26 is fixedly connected to the outer edge of the threaded rod 23 near the right end. The connecting plate 26 is fixedly connected to the inner side of the third flange 25. The third flange 25 fits into the adjacent second flange 6. Two notches 27 are opened on the right side of the ignition tube 5. The connecting plate 26 is movably inserted into the inner cavity of the adjacent notch 27.

[0017] When the boiler is ignited, the blower 1 rotates to provide airflow into the ignition tube 5. The heating wire in the ceramic ignition core 20 generates heat after being energized. Through the action of the blower 1, the heat generated by the heating wire is blown towards the biomass fuel in the boiler. The biomass fuel is ignited after reaching its ignition point. In order to quickly reach the ignition point of the biomass fuel, the honeycomb through holes 21 on the ceramic ignition core 20 are made so that the heat blown out is large and concentrated.

[0018] When installing the ceramic ignition core 20, first pass the threaded rod 23 through the second through hole 22, then put on the nut 24 and tighten it, thereby assembling the ceramic ignition core 20 onto the threaded rod 23. Then move the third flange 25 and the ceramic ignition core 20 as a whole, insert the ceramic ignition core 20 into the right end of the inner cavity of the ignition tube 5, and make the connecting plate 26 insert into the inner cavity of the adjacent notch 27. Then, use bolts 7 to install the second flange 6 and the third flange 25 on the right side of the ignition tube 5 together in a position that matches the boiler equipment, thereby fixing the ignition tube 5 and the ceramic ignition core 20 together, which is convenient for maintenance and has higher stability, avoids displacement of the ceramic ignition core 20, and ensures the normal operation of ignition.

[0019] Example 2 like Figure 3 , Figure 4 and Figure 5As shown, a rotating shaft 8 is rotatably connected to the inner cavity of the ignition tube 5. A wind baffle 9 is fixedly connected to the outer edge of the rotating shaft 8. The wind baffle 9 is located in the inner cavity of the ignition tube 5. A gear 10 is fixedly sleeved near the front end of the outer edge of the rotating shaft 8. A rocker wheel 11 is fixedly connected to the front end of the rotating shaft 8. A crossbar 12 is provided on the left side of the gear 10. A mounting plate 13 is fixedly connected to the left side of the crossbar 12. A first through hole 14 is provided on the mounting plate 13.

The top of the movable rod 15 is fixedly connected to the spring 18, which is fixedly connected to the top of the horizontal bar 12. Two bolts 7 are movably connected through the adjacent first through hole 14. The first flange 4 and the mounting plate 13 are connected to the adjacent second flange 6 by bolts 7.

[0020] When it is necessary to control the airflow, first flip the movable rod 15 upwards. The movable rod 15 flips upwards with the pin 17 as the center, and at the same time, the spring 18 deforms. The movable rod 15 drives the locking block 19 away from the gear 10, thereby releasing the gear 10 from the fixed shaft 8. Then rotate the rocker wheel 11. The rocker wheel 11 drives the baffle 9 to rotate through the shaft 8, thereby controlling the airflow and ensuring efficient heat output. After the airflow is adjusted, release the force on the movable rod 15. The movable rod 15 flips downwards under the elastic action of the spring 18. The locking block 19 engages with the gear 10, thereby lowering the fixed baffle 9 and ensuring the stability of the airflow.

[0021] Implementation Scheme: This utility model discloses a high-temperature resistant ceramic igniter for a biomass boiler. During use, the left side of the ignition cylinder 5 is installed on the first flange 4 by bolts 7. Then, the third flange 25 is moved, and the third flange 25 drives the threaded rod 23 through the second through hole 22. After that, the nut 24 is put on and tightened, thereby assembling the ceramic ignition core 20 on the threaded rod 23. Then, the third flange 25 and the ceramic ignition core 20 are moved as a whole, and the ceramic ignition core 20 is inserted into the right end of the inner cavity of the ignition cylinder 5, so that the connecting plate 26 is inserted into the inner cavity of the adjacent notch 27. The third flange 25 is fitted with the adjacent second flange 6. Then, the second flange 6 and the third flange 25 on the right side of the ignition cylinder 5 are installed together in a position suitable for the boiler equipment by bolts 7.

[0022] When the boiler is ignited, the blower 1 rotates to provide airflow into the ignition tube 5. The heating wire in the ceramic ignition core 20 generates heat after being energized. Through the action of the blower 1, the heat generated by the heating wire is blown towards the biomass fuel in the boiler. The biomass fuel is ignited after reaching its ignition point. In order to quickly reach the ignition point of the biomass fuel, the honeycomb through holes 21 on the ceramic ignition core 20 are made so that the heat blown out is large and concentrated.

[0023] When it is necessary to control the airflow, first flip the movable rod 15 upwards. The movable rod 15 flips upwards with the pin 17 as the center, and at the same time, the spring 18 deforms. The movable rod 15 drives the locking block 19 away from the gear 10, thereby releasing the gear 10 from the fixed shaft 8. Then rotate the rocker wheel 11. The rocker wheel 11 drives the baffle 9 to rotate through the shaft 8, thereby controlling the airflow and ensuring efficient heat output. After the airflow is adjusted, release the force on the movable rod 15. The movable rod 15 flips downwards under the elastic action of the spring 18. The locking block 19 engages with the gear 10, thereby lowering the fixed baffle 9 and ensuring the stability of the airflow.

[0024] When installing the ceramic ignition core 20, the threaded rod 23 is first passed through the second through hole 22, and then the nut 24 is put on and tightened, thereby assembling the ceramic ignition core 20 onto the threaded rod 23. Then, the third flange 25 and the ceramic ignition core 20 are moved as a whole, and the ceramic ignition core 20 is inserted into the right end of the inner cavity of the ignition tube 5, so that the connecting plate 26 is inserted into the inner cavity of the adjacent notch 27. Then, the second flange 6 and the third flange 25 on the right side of the ignition tube 5 are installed together in a position compatible with the boiler equipment by bolts 7, thereby fixing the ignition tube 5 and the ceramic ignition core 20 together, which is convenient for maintenance and has higher stability, avoids displacement of the ceramic ignition core 20, and ensures the normal operation of ignition.
