[0028] See also Figure 1-Figure 2 As shown, the high-efficiency cooling grate cooler structure described in this embodiment includes a base 1, a grate conveying mechanism 2, a first cold air conveying mechanism 3, a second cold air conveying mechanism 4 and a hot air recovery pipe 5, the grate conveying mechanism 2 is installed on the base 1, and a cover body 6 is provided on the grate conveying mechanism 2, the first cold air conveying mechanism 3 is installed on the base 1, and is used to deliver cold air to the bottom end of the grate conveying mechanism 2, the second cold air conveying mechanism 4 is installed on the base 1, and the second cold air conveying mechanism 4 is provided with an air supply pipe 41, and the air supply pipe 41 extends from the top of the cover body 6, and is used to deliver air into the cover body 6, and the hot air recovery pipe 5 is connected to the side of the cover body 6, and is used to recover the hot air in the cover body 6.

[0029] This embodiment has a simple structure and a reasonable design. A first cold air conveying mechanism 3 is provided to deliver cold air from below the grate plate to cool the material layer, and a second cold air conveying mechanism 4 is provided to deliver air to take away the heat on the surface of the material layer to further cool the material layer. The hot air formed after cooling enters the hot air recovery pipe 5 for recovery so as to be utilized in the back-end process.

[0030] Furthermore, the air supply pipe 41 is provided with a connecting pipe 42 and an air blowing pipe 43 . The connecting pipe 42 extends into the cover body 6 . The air blowing pipe 43 is located in the cover body 6 and connected to the connecting pipe 42 for supplying air into the cover body 6 .

[0031] Specifically, the air blowing pipe 43 is arranged along the conveying direction of the grate conveying mechanism 2 and is located in the middle position of the grate conveying mechanism 2 .

[0032] Specifically, the air blowing pipe 43 is provided with two rows of air blowing ports 431 , and the two rows of air blowing ports 431 are respectively distributed toward both sides of the conveying direction of the grate plate conveying mechanism 2 .

[0033] In this embodiment, the air blowing pipe 43 is specifically arranged in the middle position, and two rows of air blowing ports 431 are arranged to blow air toward both sides to take away the hot air from both sides, thereby achieving efficient cooling.

[0034] On the basis of the above-mentioned embodiment, the hot gas recovery pipe 5 is respectively connected to the two sides of the cover body 6 corresponding to the conveying direction of the grate conveying mechanism 2 .

[0035] In this embodiment, by cooperating with two rows of air outlets 431 and connecting the two sides of the cover body 6 to the hot air recovery pipe 5, hot air can be absorbed from both sides to achieve efficient cooling.

[0036] In some embodiments, the first cold air delivery mechanism 3 is provided with a fan 31, a refrigeration structure 32, an air delivery pipe 33 and an air supply hood 34.

By setting the refrigeration structure 32, the gas delivered by the fan 31 can be cooled, and then delivered to the air supply hood 34 through the air delivery pipe 33, and then blown upward from the bottom of the grate plate to take away the heat of the material layer on the grate plate, thereby achieving efficient cooling. The heat brought out is located above the material layer, and can be quickly blown away by the second cold air delivery mechanism 4. The hot air is then recovered through the hot air recovery pipe 5 to achieve efficient cooling. The second cold air delivery mechanism 4 here can selectively be provided with a cooling component to deliver cold air, or directly deliver normal temperature air, because the cold air blown by the first cold air delivery mechanism 3 has brought out a large amount of heat from the material layer and the gas temperature is relatively high, so normal temperature air can be used to blow away the hot air.

[0038] Specifically, in this embodiment, a filter is installed at the air inlet end of the fan 31.

[0039] In this embodiment, a filter is provided to prevent impurities from entering and affecting the normal operation of the cooling structure.

[0040] Specifically, in this embodiment, an air distribution plate 341 is provided at the position where the air supply hood 34 is connected to the air delivery pipe 33 .

[0041] In this embodiment, by providing the air distribution plate 341, the cold air is distributed and then enters the grate plate to ensure the cooling effect.

[0042] In some embodiments, an air induction structure 51 is installed on the hot gas recovery pipe 5 .

[0043] In this embodiment, by providing the air induction structure 51, the hot air in the cover body 6 can be quickly drawn out to achieve efficient cooling.
