[0030] As a further implementation of the scheme, the firepower adjusting fin assembly 43 comprises fins 431, the number of the fins 431 being four, the four fins 431 being equidistantly arranged in a circular arrangement, a metal cleaning brush 433 being attached to the fire exit tray body 31, the surface of the fire exit tray body 31 and the edge of the fire exit opening 32 being cleaned in real time during the rotation of the fins 431, preventing the accumulation of residues, dust and other impurities generated by incineration, affecting the fire exit efficiency and the service life of the equipment, a metal cleaning plate 432 being fixedly connected to the inner wall of the fin 431, the metal cleaning brush 433 being fixedly connected to the top of the metal cleaning plate 432, a metal ball 434 being fixedly connected to the bottom of the inner wall of the metal cleaning plate 432, the metal ball 434 being located inside the connecting groove 34, the metal ball 434 being in sliding fit with the connecting bead 35, a connecting seat 435 being fixedly connected to the bottom end of the outer side of the fin 431, the connecting seat 435 providing stable support for the connection of the fin 431 and the transmission gear ring 44, and guaranteeing the stability of the overall structure;
[0031] As a further implementation of the scheme, the number of the fire exit openings 32 is four, the four fire exit openings 32 being equidistantly arranged in a circular arrangement, the top view shape of the fire exit opening 32 being isosceles trapezoidal, the upper side of the isosceles trapezoid being narrow and the lower side being wide, this shape being more convenient for controlling the size of the firepower;
[0032] As a further implementation of the present scheme, the inner side of the adapter groove 34 is arc-shaped, the adapter groove 34 is located on the same central axis as the fire outlet disc body 31, and the number of adapter beads 35 is several, the several adapter beads 35 are arranged in a circular array at equal intervals, and the several adapter beads 35 arranged at equal intervals are matched with the metal ball 434 to generate stable and continuous vibration effect during the sliding of the metal ball 434, which not only helps the metal cleaning brush 433 to shake off impurities, but also prevents the accumulation of impurities in the fire outlet port 32 to some extent, avoiding the influence of impurities on the accuracy of flame flow and fire adjustment;
[0033] As a further implementation of the present scheme, the lower surface of the fastening nut 45 is provided with a dustproof disc 46, the dustproof disc 46 is sleeved outside the connecting screw 33, and the dustproof disc 46 is located above the bearing 41. In this way, dust, ash and other impurities generated during garbage incineration can be effectively prevented from entering the bearing 41.
[0034] Work flow: when the equipment is installed, the fire outlet disc body 31 as the core component is fixed inside the garbage incineration power generation furnace body 1, and is stably connected through the furnace inner base plate 2. The connecting screw 33 is vertically fixed at the top center of the fire outlet disc body 31. The fire adjustment cover 4 is sleeved on the connecting screw 33 through the bearing 41. The fastening nut 45 is screwed along the central connecting screw 33 to accurately position the fire adjustment cover 4. The dustproof disc 46 covers the top of the bearing 41 to prevent dust from entering. At this time, the fire outlet ports 32 uniformly distributed on the fire outlet disc body 31 are in an initial fully open state, ready for ignition operation. When the garbage incineration power generation furnace needs to adjust the fire, the driving motor 5 receives the control instruction to start, and its transmission shaft drives the driving gear 6 to tightly mesh with the transmission gear ring 44 for transmission. The transmission gear ring 44 drives the fire adjustment fin assembly 43 to rotate around the central connecting screw 33. Due to the curved surface characteristics of the fire outlet disc body 31, the fins 431 can shield the fire outlet ports 32 during rotation. Specifically, when in the large fire mode, the fins 431 are rotated to a certain angle to maximize the exposed area of the fire outlet ports 32 on the spherical surface. The flame flows into the furnace through the fire outlet ports 32 to strengthen the combustion reaction and increase the fire, meeting the high-load power generation demand. When in the small fire mode, the fins 431 are further rotated to increase the shielding range of the fire outlet ports 32, limit the amount of flame flowing in, slow down the combustion speed, and reduce the fire output to adapt to the low-load operation scenario.
[0035] While the fins 431 rotate around the fire outlet disc body 31 to adjust the fire, the automatic ash removal process is also carried out. The metal cleaning brush 433 on the metal cleaning plate 432 inside the fin 431 closely adheres to the curved surface of the fire outlet disc body 31 and sweeps along the edge of the fire outlet port 32 during rotation, effectively removing the slag, dust and other impurities generated by garbage incineration and adhering to the surface of the fire outlet disc body 31 and the periphery of the fire outlet port 32.
[0036] In addition, when the metal cleaning brush 433 at the bottom of the metal cleaning plate 432 is in sliding fit with the abutment groove 34 at the bottom outside of the fire plate body 31, the metal ball 434 constantly rubs and collides with the abutment bead 35 during rotation, thereby generating a vibration effect, and the vibration is transmitted to the wing 431 and the metal cleaning brush 433, so that the impurities attached to the metal cleaning brush 433 are shaken off completely, preventing the metal cleaning brush 433 from being blocked and ensuring that the dust cleaning work is continuously and efficiently carried out. When the device has been operated for a certain period of time, if maintenance and repair are required for the components such as the fire plate body 31 corner and the fire power adjusting cover 4, a special tool is used to loosen the fastening nut 45, the fire power adjusting cover 4 is detached from the connecting screw rod 33, the stubborn impurities at the corner of the fire plate body 31 are removed, the wear degree of the components such as the wing 431 and the metal cleaning brush 433 is carefully checked, targeted repair or replacement is carried out, and after the maintenance and repair are completed, the components are reset in the original installation order, the fire power adjusting cover 4 is fixed again through the fastening nut 45, and the device is ensured to return to the normal operating state.
[0037] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
