These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0036] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0037] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a cooling device provided in an embodiment of the present application. Figure 2 yes Figure 1 The cooling device may include a base 100 , a material pipe 200 , a drive assembly 300 and a cooling liquid spray assembly 400 .

[0038] The material pipe 200 in the cooling device can be mounted on the base 100 and can be rotatably connected to the base 100. The material pipe 200 can have a cavity a1 and a spiral plate 201 fixed to the inner side wall of the cavity a1. The extension direction of the spiral plate 201 can be parallel to the length direction f1 of the material pipe 200. For example, the feed port b1 of the material pipe 200 can be connected to the discharge port of a rotary kiln (not shown in the figure). The material can enter the cavity a1 through the feed port b1 of the material pipe 200 and be discharged from the discharge port b2 of the material pipe 200 after cooling. It should be noted that the material of the material pipe 200 needs to be selected according to the material to be cooled and is not specifically limited here.

[0039] The drive assembly 300 in the cooling device can be mounted on the base 100 and can be in transmission connection with the material pipe 200. The drive assembly 300 can be configured to drive the material pipe 200 to rotate. Here, the drive assembly 300 can drive the material pipe 200 to rotate around the axis of the material pipe 200.

[0040] The cooling liquid spray component 400 in the cooling device can be connected to the base 100 . The cooling liquid spray component 400 can have a liquid spray port c1 . The cooling liquid spray component 400 can be configured to spray coolant onto the outer side of the material pipe 200 through the liquid spray port c1 .

[0041] In the embodiment of the present application, as the drive assembly 300 rotates the material pipe 200, the spiral plate 201 disposed within the cavity a1 of the material pipe 200 drives the material to move within the material pipe 200. Simultaneously, the cooling liquid spray assembly 400 disposed outside the material pipe 200 sprays coolant onto the outer surface of the material pipe 200 to absorb heat transferred to the material pipe 200, thereby effectively cooling the material. Furthermore, while the spiral plate 201 drives the material to move, it can also turn the material over, further improving the efficiency of cooling all the material within the material pipe 200.

[0042] In summary, the embodiments of the present application provide a cooling device that may include: a base, a material pipe, a drive assembly, and a cooling liquid spray assembly. As the drive assembly drives the material pipe to rotate, a spiral plate disposed within the cavity of the material pipe drives the material to move within the pipe. Simultaneously, a cooling liquid spray assembly disposed outside the pipe sprays coolant onto the outer surface of the pipe to absorb heat transferred to the pipe, thereby effectively cooling the material. Furthermore, the spiral plate can simultaneously turn the material over while driving the material to move, further improving the efficiency of cooling all material within the pipe.

[0043] Optional, please refer to Figure 3 , Figure 3: This is a schematic diagram of the structure of another cooling device provided by an embodiment of the present application. The cooling liquid sprinkling assembly 400 may include: an infusion line 401, which may be located on the side of the material pipe 200 facing away from the base 100. One end of the infusion line 401 may be used to connect to a liquid storage tank (not shown in the figure), and the infusion line 401 may have multiple sprinkling ports c1 distributed toward the outer side of the material pipe 200. The extension direction of the infusion line 401 may be parallel to the length direction of the material pipe 200. In this case, by arranging the infusion line 401 on the side of the material pipe 200 facing away from the base 100, and providing the infusion line 401 with multiple sprinkling ports c1 distributed toward the material pipe 200, the cooling liquid guided from the liquid storage tank into the infusion line 401 can flow from the multiple sprinkling ports c1 of the infusion line 401 to the outer side of the material pipe 200 under the action of gravity, thereby dissipating heat and cooling the material pipe 200. For example, multiple spray ports c1 are arranged along the length of the material pipe 200, increasing the number of cooling spray points and further improving cooling efficiency. It should be noted that in other possible implementations, a pressurizing component can be used to increase the pressure of the coolant flowing into the infusion line 401, so that the coolant is sprayed from the spray ports c1 toward the outer side of the material pipe 200. In this way, the infusion line 401 can be arranged at any position on the outer side of the material pipe, so that the spray ports c1 face the outer side of the material pipe 200.

[0044] In the embodiments of this application, Figure 3 As shown, the liquid delivery line 401 in the cooling liquid spray assembly 400 may include: a main line 401a and at least two sub-line lines 401b. The at least two sub-line lines 401b may be located between the main line 401a and the outer side of the material pipe 200. The at least two sub-line lines 401b may be arranged side by side along the length of the material pipe 200. Each sub-line line may include at least one branch line, a portion of which is parallel to the length of the material pipe 200. The main line 401a may be connected to a liquid storage tank, and the branch lines may have liquid spray ports c1 distributed toward the outer side of the material pipe 200. In this way, the coolant first enters the main line 401a from the liquid storage tank, and then the coolant in the main line 401a flows to each branch line. In this way, the number of cooling spray points is further increased, and the cooling efficiency is improved.

[0045] For example, Figure 3 As shown, each group of pipelines 401 b may include two branch pipelines, and the two branch pipelines may be arranged opposite to each other along a direction f2 perpendicular to the length direction f1 of the material pipe 200 .

[0046] Optional, such as Figure 3As shown, the cooling device may further include: a plurality of annular heat-conducting ribs 500, which may be arranged in an array along the length of the material pipe 200, and each annular heat-conducting rib 500 may be sleeved and fastened to the outer side of the material pipe 200. In this case, by providing multiple annular heat-conducting ribs 500 on the outer side of the material pipe 200, the annular heat-conducting ribs 500 can effectively increase the heat dissipation area of the material pipe 200. After heat is transferred to the annular heat-conducting ribs 500, the cooling liquid assembly 400 sprays coolant to reduce the temperature. For example, the material pipe 200 and the multiple annular heat-conducting ribs 500 may be integrally formed.

[0047] In the examples of this application, please refer to Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the structure of another cooling device provided in an embodiment of the present application. Figure 5 yes Figure 4 The top view of the cooling device is shown. The cooling device may further include: a first roller 600, a second roller 700, a first supporting roller 800, and a second supporting roller 900. The first roller 600 and the second roller 700 may be fastened to the outer side of the material pipe 200, and the first roller 600 and the second roller 700 may be respectively located at the two ends of the material pipe 200. The first supporting roller 800 and the second supporting roller 900 may be mounted on the base 100 and rotatably connected to the base 100. The first roller 600 and the first supporting roller 800 are in sliding contact with each other, and the second roller 700 and the second supporting roller 900 are in sliding contact with each other. In this way, through the cooperation between the first roller 600 and the first supporting roller 800, and the cooperation between the second roller 700 and the second supporting roller 900, a good rotational support effect can be provided for the material pipe 200.

[0048] Optional, such as Figure 4 and Figure 5As shown, the cooling device may further include: multiple sets of first roller positioning members distributed along the circumference of the material pipe 200 and fixedly connected to the outer side surface of the material pipe 200, and multiple sets of second roller positioning members distributed along the circumference of the material pipe 200 and fixedly connected to the outer side surface of the material pipe 200. Each set of first roller positioning members may include two first positioning blocks 1000 arranged opposite each other along the length of the material pipe 200, with a first positioning groove d1 formed between the two first positioning blocks 1000. A portion of the first roller 600 may be positioned within the first positioning groove d1, and two side surfaces of the first roller 600 may respectively abut against the two first positioning blocks 1000. Each set of second roller positioning members may include two second positioning blocks 1100 arranged opposite each other along the length of the material pipe 200, with a second positioning groove d2 formed between the two second positioning blocks 1100. A portion of the second roller 700 may be positioned within the second positioning groove d2, and two side surfaces of the second roller 700 may respectively abut against the two second positioning blocks 1100.

[0049] In this case, multiple sets of first roller positioning members and multiple sets of second roller positioning members are fixed to the outer side of the material pipe 200. The first roller 600 is clamped and installed using two first positioning blocks 1000 in the first roller positioning members, and the second roller 700 is clamped and installed using two second positioning blocks 1100 in the second roller positioning members. This makes installation of the two rollers convenient and ensures high installation accuracy. Furthermore, when welding the two rollers directly to the material pipe 200, the longer material pipe 200 may bend and deform. However, when welding the positioning blocks to the material pipe, the welding area is smaller, making the probability of bending and deformation of the material pipe lower.

[0050] In the examples of this application, please refer to Figure 6 and Figure 7 , Figure 6 This is a schematic structural diagram of another cooling device provided in an embodiment of the present application. Figure 7 yes Figure 6A cross-sectional view of the cooling device is shown. The cooling device may also include: an outer cover shell 1200 fixedly connected to the base 100, the outer cover shell 1200 may extend along the circumference of the material pipe 200 and along the length direction of the material pipe 200, and is used to cover at least part of the outer side surface of the material pipe 200, and the outer cover shell 1200 may form a gap e1 with the outer side surface of the material pipe 200. The sprinkling port c1 in the cooling sprinkling assembly 400 may be located within the gap e1. In this case, by arranging the outer cover shell 1200 on the periphery of the material pipe 200 and arranging the sprinkling port c1 in the cooling sprinkling assembly 400 within the gap e1, the outer cover shell 1200 can collect the splashing coolant to avoid splashing into other areas, thereby ensuring the reliability and user experience of the cooling device. It should be noted that when the cooling device includes the outer cover shell 1200, the cooling sprinkling assembly 400 can be mounted on the outer cover shell 1200.

[0051] For example, when the cooling device includes a branch pipe, a first roller 600, a second roller 700, and an annular heat-conducting rib 500, the branch pipe, the first roller 600, the second roller 700, and the annular heat-conducting rib 500 can be distributed in the gap e1 formed between the outer housing 1200 and the material pipe 200. The outer housing 1200 can have two openings e2 corresponding to the first roller 600 and the second roller 700, respectively. The first roller 600 can be in sliding contact with the first supporting roller 800 at one opening e2, and the second roller 700 can be in sliding contact with the second supporting roller 900 at the other opening e2.

[0052] Optionally, the outer shell 1200 may have a drain port (not shown) communicating with the gap e2 , so that the coolant collected in the outer shell 1200 can be promptly discharged through the drain port.

[0053] In the embodiments of this application, Figure 6 and Figure 7 As shown, the drive assembly 300 may include a drive motor 301, a reduction gear 302, and a transmission mechanism 303. The output shaft of the drive motor 301 may be drivingly connected to the input shaft of the reduction gear 302, and the transmission mechanism 303 may be drivingly connected to the output shaft of the reduction gear 302 and the material pipe 200, respectively. In this way, the drive motor 301 can drive the transmission mechanism 303 via the reduction gear 302, thereby driving the material pipe 200 to rotate. For example, the transmission mechanism 303 may include a sprocket 303a fixed to the end of the material pipe 200, and a chain (not shown) connected to the sprocket 303a and the output shaft of the reduction gear 302, respectively.

[0054] In summary, the embodiments of the present application provide a cooling device that may include: a base, a material pipe, a drive assembly, and a cooling liquid spray assembly. As the drive assembly drives the material pipe to rotate, a spiral plate disposed within the cavity of the material pipe drives the material to move within the pipe. Simultaneously, a cooling liquid spray assembly disposed outside the pipe sprays coolant onto the outer surface of the pipe to absorb heat transferred to the pipe, thereby effectively cooling the material. Furthermore, the spiral plate can simultaneously turn the material over while driving the material to move, further improving the efficiency of cooling all material within the pipe.
