Description

Technical Field

[0001] The utility model relates to the technical field of casting sand boxes, in particular to a cooling mechanism of a casting sand box. Background Art

[0002] As the demand for wind turbine mainframes gradually increases, castings need to be cooled in time during the production process to enter the next process flow. When cooling the castings, the cooling speed needs to be increased as much as possible to speed up the production speed of parts and improve the utilization rate of the sand box.

[0003] The existing process is to add exhaust holes on the sand box and cooling ribs inside the sand box. However, the cooling efficiency of ordinary air holes and cooling ribs is relatively low. At the same time, since the cooling ribs are welded to the sand box by a single steel plate, the structural strength is insufficient and the cooling ribs are easy to fall off after long-term use. Utility Model Content

[0017] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0018] The cooling mechanism of the casting sand box according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0019] like Figure 1-Figure 3 As shown, the cooling mechanism of the casting sand box according to the embodiment of the present invention may include: a water cooler 1, a water inlet pipe 2, a plurality of rib plate components 3, a plurality of connecting pipes 4 and a return pipe 5.

[0020] One end of the water inlet pipe 2 is connected to the water cooler 1 .

[0021] It should be noted that the specific structure of the water cooler 1 described in this embodiment has been disclosed in the prior art, so it will not be described in detail here.

[0022] A plurality of rib members 3 are respectively arranged on the inner wall of the flask, and a cavity 34 is provided inside the rib member 3 .

[0023] It should be noted that the cavity 34 is arranged in a V-shaped structure with its opening facing the inner wall of the flask. It is understandable that this embodiment can increase the contact area between the rib member 3 and the flask, thereby increasing the stability of the rib member 3 and extending the service life of the mechanism.

[0024] The other end of the water inlet pipe 2 passes through the outer wall of the sand box, and the other end of the water inlet pipe 2 is connected to a cavity 34;

[0025] A plurality of connecting pipes 4 are provided between the corresponding two rib plate components 3;

[0026] One end of the return pipe 5 passes through the outer wall of the sand box, one end of the return pipe 5 is communicated with another cavity 34 , and the other end of the return pipe 5 is communicated with the water cooler 1 .

[0027] It should be noted that the casting volume of general wind power equipment is large, and the volume of the sand box is also large. Multiple rib plate components 3 can be installed inside the sand box. Multiple rib plate components 3 are welded to the inner wall of the sand box. Multiple rib plate components 3 are connected by connecting pipes 4, and the connecting pipes 4 can be metal pipes.

[0028] One of the two adjacent rib plate components 3 is connected to the water inlet pipe 2, and the other is connected to the water return pipe 5, thereby forming a circulating water loop.

[0029] Specifically, wind power equipment produced by casting (for example: wind power main engine casing) needs to be cooled by using a sand box. It is placed in the sand box, and then the cooling mechanism is started. The water cooler 1 injects low-temperature water into the cavity 34 inside a rib plate component 3 through the water inlet pipe 2. Under the connection of the connecting pipe 4, the cavity 34 inside multiple rib plate components 3 is filled with cold water. The cold water exchanges heat with the sand box with higher temperature, thereby achieving the purpose of cooling. The water temperature in the cavity 34 increases, and then returns to the water cooler 1 through the return pipe 5 for heat exchange and cooling. In this way, a cooling water circulation is formed inside the sand box, thereby improving the cooling efficiency.

[0030] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the rib component 3 includes two cooling ribs 31 , an upper cover plate 32 and a lower cover plate 33 .

[0031] The two cooling ribs 31 are connected, and the cross-section of the two cooling ribs 31 is arranged in a V-shaped structure. The upper cover plate 32 is arranged on the upper part of the two cooling ribs 31, and the lower cover plate 33 is arranged on the bottom of the two cooling ribs 31.

[0032] It should be noted that in the prior art, the rib plate and the inner wall of the sand box form a right-angle structure, which easily causes sand blocks to get stuck in the sand box and is not easy to clean. A pneumatic shovel is required for cleaning, which not only increases the workload of workers, but also easily damages the rib plate. Entering the sand box to clean the sand blocks also endangers personnel safety.

[0033] It can be understood that the cross-section of the two cooling ribs 31 is arranged in a V-shaped structure, so that there is an obtuse angle structure between the cooling ribs 31 and the inner wall of the sand box, which reduces the sand blocks stuck on the sand box, reduces the work intensity of the workers, and ensures the safety of personnel and the ribs inside the sand box.

[0034] In one embodiment of the present invention, Figure 1 As shown, one communicating pipe 4 is located at the upper position of the two rib plate parts 3, and the other communicating pipe 4 is located at the lower position of the two rib plate parts 3, and the two communicating pipes 4 are arranged adjacent to each other.

[0035] It is understandable that the multiple connecting pipes 4 are arranged in an up-and-down staggered manner between the multiple rib plate components 3, which enables cooling water to flow between the multiple rib plate components 3, thereby quickly taking away heat to achieve the purpose of efficient cooling.

[0036] In summary, the cooling mechanism of the casting sand box of the present invention improves the cooling efficiency of the sand box by constructing a circulating water channel between multiple rib plate components, increases the contact area between the rib plate components and the sand box, and enhances the structural strength, thereby extending the service life of the rib plate components.
