Description

Technical Field

[0001] This utility model relates to the field of waste incineration equipment components, and in particular to a tilting grate. Background Technology

[0002] The tilting grate is an important component in waste incineration equipment, and its function is to support the burning material.

[0003] Currently, CN219674252U, titled "Gas Grating for Waste Incinerator and Waste Incinerator," discloses a grate body with protrusions on its material feeding surface. These protrusions are designed to bounce when the upper grate moves along the material feeding surface to near the end. During use, the grate body supports waste, and its temperature rises due to heating. However, since the grate body is a flat plate, its heat dissipation area is limited, making it prone to heat accumulation and overheating damage.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model discloses a tilting grate.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A rotating grate includes grate bars and a grate support frame, wherein the grate bars and the grate support frame are connected as one unit; the bottom of the grate bars is provided with a first heat dissipation cavity, a second heat dissipation cavity and a third heat dissipation cavity, wherein the first heat dissipation cavity is provided with a plurality of parallel first heat dissipation fins, the second heat dissipation cavity is provided with a plurality of parallel second heat dissipation fins, and the third heat dissipation cavity is provided with a plurality of parallel third heat dissipation fins; the grate support frame includes a frame body and a side plate, wherein the side plate is provided on the side of the frame body.

[0008] Furthermore, the first heat dissipation cavity is located in the middle of the bottom of the grate plate, and the second and third heat dissipation cavities are located on the left and right sides of the first heat dissipation cavity, respectively.

[0009] Furthermore, a pair of adapter plates are provided on the bottom surface of the grate plate, and the adapter plates have several grooves.

[0010] Furthermore, several reinforcing ribs are provided between the left and right sides of the adapter plate and the grate plates.

[0011] Furthermore, the rear of the frame is provided with a pivot connection part, and the pivot connection part has a through hole in the center.

[0012] Furthermore, the inner side of the side plate is provided with a plurality of parallel ribs, which are parallel to the wide side of the side plate.

[0013] Furthermore, a curved plate is provided on one wide side of the grate plate, and the curved plate has several notches along its length.

[0014] Furthermore, several snap-fit ​​buckles are provided on the long side of the side plate. When the grate plate and the grate support frame are installed as a whole, the snap-fit ​​buckles are engaged in the notches of the curved plate.

[0015] Furthermore, the side plate has several air holes arranged along the long side of the side plate.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. The bottom of the grate is equipped with three heat dissipation chambers. Each heat dissipation chamber is divided into several cavities by heat dissipation fins. The contact area between the air and the grate and the heat dissipation fins is increased, which helps the grate to dissipate heat in time and reduces the possibility of the grate being damaged by overheating.

[0018] 2. The stiffening ribs serve two purposes: firstly, they support the first heat sink and improve its structural strength; secondly, they increase the heat dissipation area and improve the heat dissipation effect.

[0019] 3. The notch of the curved plate and the snap-fit ​​of the side plate correspond to each other, improving installation accuracy.

[0020] 4. Strengthen the two sides of the rib support transition plate to further improve its structural stability.

[0021] 5. Rib plates support the side plates, improving structural stability, and the grate support frame includes a hollow structure, which helps to reduce its weight.

[0022] 6. The vents on the side plates connect the space inside and outside the grate, allowing for air exchange and facilitating heat dissipation from the grate plates, thus improving heat dissipation. Attached Figure Description

[0032] Example 1:

[0033] A type of rotating grate 1, such as Figure 1 and Figure 2 As shown, it includes grate plate 1 and grate support frame 2, which are integrally cast and formed, with grate plate 1 located on top of grate support frame 2.

[0034] like Figure 2 As shown, the top of the grate bar 1 is mostly flat, and the flat surface is connected to the arc surface. The material to be burned is placed on the top of the grate bar 1.

[0035] like Figure 2As shown, the bottom of the grate plate 1 is provided with a first heat dissipation cavity 11, a second heat dissipation cavity 12 and a third heat dissipation cavity 13. The first heat dissipation cavity 11 is located in the middle of the bottom of the grate plate 1, and the second heat dissipation cavity 12 and the third heat dissipation cavity 13 are located on the left and right sides of the first heat dissipation cavity 11, respectively. When working, the hot air generated by combustion flows from bottom to top into the first heat dissipation cavity 11, the second heat dissipation cavity 12 and the third heat dissipation cavity 13. The heat dissipation area at the bottom of the grate plate 1 is increased through the three heat dissipation cavities, which is beneficial to the heat dissipation of the grate plate 1.

[0036] like Figure 2 As shown, a plurality of parallel first heat dissipation fins 111 are arranged in the first heat dissipation cavity 11. The first heat dissipation fins 111 are parallel to the length direction of the grate plate 1, thereby increasing the heat dissipation area of ​​the first heat dissipation fins 111.

[0037] like Figure 2 As shown, a number of parallel second heat dissipation fins 121 are provided in the second heat dissipation cavity 12. The second heat dissipation fins 121 are also parallel to the length direction of the grate plate 1 in order to further increase the heat dissipation area.

[0038] like Figure 2 As shown, several parallel third heat dissipation fins 131 are arranged in the third heat dissipation cavity 13. The third heat dissipation fins 131 are also parallel to the length direction of the grate plate 1 in order to further increase the heat dissipation area.

[0039] like Figure 2 As shown, a pair of transition plates 15 are provided on the bottom surface of the grate plate 1. The transition plates 15 are parallel to the long side of the grate plate 1. Several grooves 151 are opened on the transition plates 15. The cross-section of the grooves 151 is arc-shaped. When the grate plate 1 is flipped and installed in the incinerator, the rotating shaft of the incinerator passes through the grooves 151 of the transition plates 15.

[0040] like Figure 2 As shown, the grate support frame 2 includes a frame body 21 and side plates 22. The side plates 22 are disposed on the side of the frame body 21, and the side plates 22 and corresponding heat sinks are integrated. The side plates 22 have a plurality of air holes 23 arranged along the long side of the side plates 22. Air can flow through the air holes 23, accelerating the internal and external air flow, thereby dissipating heat outward and preventing the grate plates 1 from overheating.

[0041] like Figure 2 As shown, the side plate 22 is provided with several parallel ribs 222, which are parallel to the wide side of the side plate 22 and serve to support the side plate 22.

[0042] like Figure 2As shown, the rear of the frame 21 is provided with a rotating shaft connection part 211, and a through hole is opened in the center of the rotating shaft connection part 211. When the grate plate 1 and the grate support frame 2 are installed as a whole, the through hole and the groove 151 of the rotating shaft connection part 211 are arranged coaxially, and the rotating shaft of the incinerator passes through it. The rotation of the rotating shaft of the incinerator can cause the entire grate to flip.

[0043] Example 2:

[0044] A type of rotating grate 1, such as Figure 1 As shown, it includes grate bars 1 and grate support frame 2, which are spliced ​​together.

[0045] like Figure 3 and Figure 4 As shown, a curved plate 14 is provided on one wide side of the grate plate 1. The curved plate 14 is arc-shaped and has several notches 141 along its length. Several reinforcing ribs 152 are provided between the left and right sides of the transition plate 15 and the grate plate 1 to improve the structural strength of the transition plate 15.

[0046] like Figure 5 and Figure 6 As shown, the grate support frame 2 includes a frame body 21 and side plates 22, with the side plates 22 disposed on the side of the frame body 21. Several snap-fit ​​buckles 221 are provided on the long side of the side plates 22, the number of which is the same as the number of grooves 151, and they correspond one-to-one. When the grate plate 1 and the grate support frame 2 are installed as a single unit, the snap-fit ​​buckles 221 engage with the grooves 151 of the adapter plate 15, thereby achieving the splicing and installation of the grate plate 1 and the grate support frame 2.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
