Technical Field

[0001] The utility model relates to the field of garbage incineration grate slices, in particular to a garbage incineration grate slice. Background Art

[0002] In existing waste incineration technology, the grate is a key component of the incinerator, and its design directly affects the incineration efficiency, combustion stability, and equipment maintenance costs. Traditional waste incineration grate fins often include ventilation holes in their structure to provide the necessary air flow into the furnace to promote sufficient combustion of waste. However, this design faces a significant problem in practical application: the ventilation holes are easily clogged.

[0003] Specifically, due to the complex composition of garbage, which contains a variety of combustible and non-combustible substances, the ashes, incompletely burned residues and possible impurities produced during the incineration process tend to accumulate around the ventilation holes; after long-term operation, these accumulations will gradually clog the ventilation holes, resulting in poor air circulation, which in turn affects the adequacy and efficiency of garbage incineration.

[0004] Therefore, it is necessary to provide a new garbage incineration grate to solve the above technical problems. Utility Model Content

[0008] Preferably, the bottom end of the roller is tangent to the bottom end of the grate body.

[0010] Preferably, a wear-resistant layer is provided on the top of the trapezoidal bar, and the wear-resistant layer is made of a high-hardness, high-temperature resistant material to improve the wear resistance and service life of the trapezoidal bar and reduce the wear caused by long-term friction with garbage.

[0012] Compared with the related art, the garbage incineration grate provided by the utility model has the following beneficial effects:

[0013] Improved ventilation efficiency: By setting a sliding top rod and a stepped connecting plate in the hollow connecting column, an automatic cleaning mechanism for the ventilation holes is realized; this design effectively prevents the ventilation holes from being blocked, ensuring smooth air circulation, thereby improving the ventilation efficiency of the incinerator and promoting the full combustion of garbage;

[0014] Extended service life: Blockage of ventilation holes is one of the main reasons for increased wear and shortened service life of grate plates; the automatic cleaning mechanism of the present invention reduces blockage of ventilation holes and reduces the frequency of maintenance required for cleaning ventilation holes, thereby extending the service life of grate plates and reducing replacement costs.

One end of the pushing surface of the grate body 1 is fixedly connected to a trapezoidal bar 2, and one end of the grate body 1 is located between the two trapezoidal bars 2 and has ventilation holes 3 equidistantly opened. The bottom end of the grate body 1 is located at the ventilation holes 3 and is fixedly connected to the hollow connecting column 4. Several of the hollow connecting columns 4 are provided with air inlets 5 on the outside, and several hollow connecting columns 4 are slidably connected to top rods 6 inside.

The bottom end of the grate body 1 is fixedly connected to a crossbeam 8, and the inner wall of the crossbeam 8 is rotatably connected to a roller 9. The two sides of the roller 9 are respectively fixedly connected to dials The column 10 and the crossbeam 8 are movably connected with connecting pieces 11 on both sides. A shifting groove 12 is provided in the middle of the connecting piece 11, and the shifting groove 12 is slidably connected to the shifting column 10. The connecting piece 11 is fixedly connected to one end of the corresponding connecting plate 7. The bottom end of the roller 9 is tangent to the bottom end of the grate body 1. The bottom end of the grate body 1 is located at the crossbeam 8 and is fixedly connected with an air guide plate 13. The top of the trapezoidal bar 2 is provided with a wear-resistant layer, which is made of high hardness and high temperature resistant material to improve the wear resistance and service life of the trapezoidal bar 2 and reduce the wear caused by long-term friction with garbage. The roller 9 is made of high temperature resistant and wear-resistant alloy material, and the surface of the roller 9 is provided with an anti-slip texture to enhance the stability of the roller 9 during rolling and the driving effect on the connecting piece 11.

[0024] The working principle of the garbage incineration grate provided by the utility model is as follows:

[0025] Ventilation and oxygen supply:

[0026] The ventilation holes 3 opened on the grate body 1 are located between the two trapezoidal bars 2. These ventilation holes are evenly distributed to ensure that air can enter the furnace evenly and fully during the incineration process, providing the necessary oxygen for the combustion of garbage;

[0027] The hollow connecting columns 4 are fixedly connected to the bottom end of the grate body 1 and correspond to the ventilation holes 3; the outside of these hollow connecting columns is provided with air inlets 5, allowing external air to enter and pass through the inside of the hollow connecting columns and finally reach the ventilation holes 3, thereby achieving effective air circulation;

[0028] Automatic cleaning mechanism:

[0029] The top rods 6 are slidably connected inside the hollow connecting column 4, while the bottom ends of adjacent top rods are fixedly connected by connecting plates 7, and the two connecting plates are arranged in a stepped manner. This design allows the top rods to slide relative to each other when the grate moves or is subjected to external forces, thereby driving the connecting plates to move up and down.

[0030] When the connecting plate moves up and down, its edge contacts the area around the ventilation hole 3, producing a scraping effect; this scraping effect helps to remove impurities such as ash and residue accumulated around the ventilation hole, thereby keeping the ventilation hole unobstructed;

[0031] The linkage between the roller and the dial column:

[0032] The crossbeam 8 at the bottom end of the grate body 1 is rotatably connected to a roller 9, and shifting posts 10 are fixed on both sides of the roller; the movable connecting pieces 11 on both sides of the crossbeam are slidably connected to the shifting posts 10 through the shifting grooves 12 thereon;

[0033] When the roller 9 moves with the grate, the lever 10 pushes the lever slot 12, thereby driving the connecting piece 11 and the connecting plate 7 fixed thereto to move together; this linkage mechanism enhances the movement effect of the push rod and the connecting plate, helping to clean the ventilation holes more thoroughly;

[0034] Wind guidance and stability:

[0035] The air guide plate 13 at the bottom end of the grate body 1 not only helps to guide the air flow and improve ventilation efficiency, but also increases the stability of the grate to a certain extent, preventing it from deformation or displacement under high temperature and vibration environment.

[0036] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
