Description

Technical Field

[0001] This utility model relates to the field of cast iron casting cooling technology, specifically to a cast iron casting cooling device. Background Technology

[0002] In the field of metal smelting and casting, the cooling process of cast iron pipes after casting is crucial, as it directly affects the microstructure and mechanical properties of the final product. Currently, the most common cooling method in existing technologies is surface cooling of cast iron pipes using a spray system.

[0003] For example, patent CN221890858U discloses a cast iron casting cooling device, including a workbench, an operating table, multiple support seats, limiting components, multiple mounting slots, and a cooling mechanism. The multiple mounting slots are located on the operating table between two support seats. The cooling mechanism includes a cold water tank, a second pump body, a conveying pipe, and multiple sets of spraying components. The cold water tank is mounted on the workbench, the second pump body is mounted on the cold water tank, and the multiple sets of spraying components are installed in their respective mounting slots. The spraying components are connected to the second pump body via the conveying pipe. Thus, two limiting sleeves clamp the outer wall of the cast iron pipe, ensuring greater stability during transport. Simultaneously, the second pump body delivers cooling water to the conveying pipe, which is then distributed to the multiple spraying sleeves. Finally, multiple spray heads spray the cast iron pipe.

[0004] However, this cooling device has significant drawbacks. In order to achieve the ideal cooling effect during continuous production, a large amount of cooling water needs to be sprayed onto the surface of the casting continuously. After one cooling cycle, the cooling water is discharged directly without being recycled. If large-scale production is carried out, the daily water consumption is extremely considerable, which not only greatly increases the production cost of enterprises, but also goes against the current advocacy of green environmental protection, energy conservation and emission reduction, and is not conducive to the sustainable development of the casting industry. Utility Model Content

[0005] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by this utility model is: in order to achieve the ideal cooling effect during continuous production, a large amount of cooling water needs to be sprayed onto the surface of the casting continuously. After the cooling is completed once, the cooling water is directly discharged without being recycled. If large-scale production is carried out, the daily water consumption is extremely considerable, which not only greatly increases the production cost of enterprises, but also goes against the current advocacy of green environmental protection, energy conservation and emission reduction concepts, which is not conducive to the sustainable development of the casting industry.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a cast iron casting cooling device, comprising: frame; A conveying mechanism, mounted on the frame, is used to convey castings; A water tank, mounted on the frame and located below the conveying mechanism; the water tank has an opening at its upper end to collect water dripping from the conveying mechanism; and A spraying mechanism is connected to the water tank to spray water from the water tank onto the castings on the conveying mechanism.

[0007] Preferably, it also includes a filter screen and a guide plate; one end of the filter screen and the guide plate are connected to each other, and the other end of the filter screen and the guide plate are installed in the water tank to divide the water tank into an upper collection area and a lower convergence area; the guide plate is inclined to guide the water on the guide plate to the filter screen, and the spraying mechanism sprays the water in the convergence area onto the casting on the conveying mechanism.

[0008] Preferably, it further includes a rinsing mechanism, which includes: a deluge pipe, a connecting pipe, and a first pump body; the deluge pipe is installed in the collection area and is located near the end of the guide plate away from the filter screen; the deluge pipe is arranged along the width direction of the guide plate; one end of the connecting pipe is connected to the collection area, and the other end of the connecting pipe is connected to the deluge pipe; the first pump body is installed on the connecting pipe.

[0009] Preferably, the spraying mechanism includes: a second pump body, a spray pipe, and a nozzle; one end of the spray pipe is connected to a water tank, and the other end of the spray pipe is connected to the nozzle; the nozzle is located above the conveying mechanism and faces the casting on the conveying mechanism; the second pump body is mounted on the spray pipe.

[0010] Preferably, a filter is also installed on the spray pipe.

[0011] Preferably, multiple nozzles are arranged in the conveying direction of the conveying mechanism.

[0012] Preferably, the nozzle is ball-jointed to the spray pipe.

[0013] Preferably, the conveying mechanism is a chain conveyor.

[0014] Compared with the prior art, the present invention has at least the following advantages: In this invention, the conveying mechanism starts operating and continuously and stably transports the freshly poured high-temperature casting along a set path. As the conveying mechanism operates, the casting passes under the spraying mechanism in sequence. At this point, the spraying mechanism immediately starts, evenly spraying the cooling water stored in the water tank onto the surface of the casting. The cooling water comes into full contact with the high-temperature casting, rapidly absorbing the heat from the casting and achieving rapid cooling. After completing the cooling task, the cooling water drips from the surface of the casting due to gravity, precisely falling into the water tank with an opening below through the gaps in the conveying mechanism. During the dripping process, heat is dissipated from the cooling water. The water tank collects this cooling water, providing a water source for the spraying mechanism, thus forming a complete water circulation cooling system, greatly improving the efficiency of water resource utilization and realizing the recycling of water resources.

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] See Figure 1 and Figure 2The present invention provides an embodiment of a cast iron casting cooling device, comprising: a frame 1, a conveying mechanism 2, a water tank 3, and a spraying mechanism 4; the conveying mechanism 2 is mounted on the frame 1 to convey castings; the water tank 3 is mounted on the frame 1 and located below the conveying mechanism 2; the upper end of the water tank 3 is open to collect water dripping from the conveying mechanism 2; the spraying mechanism 4 is connected to the water tank 3 to spray water from the water tank 3 onto the castings on the conveying mechanism 2.

[0021] In practice, the conveying mechanism 2 starts operating, continuously and stably transporting the freshly poured high-temperature casting along a set path. As the conveying mechanism 2 operates, the casting passes under the spraying mechanism 4 in sequence. At this time, the spraying mechanism 4 immediately starts, evenly spraying the cooling water stored in the water tank 3 onto the surface of the casting. The cooling water comes into full contact with the high-temperature casting, quickly absorbing the heat of the casting and achieving rapid cooling. After completing the cooling task, the cooling water drips from the surface of the casting due to gravity, precisely falling into the water tank 3 with an opening below through the gap of the conveying mechanism 2. During the dripping process, heat is dissipated from the cooling water. The water tank 3 collects this cooling water, providing a water source for the spraying mechanism 4, thus forming a complete water circulation cooling system, greatly improving the utilization efficiency of water resources and realizing the recycling of water resources.

[0022] See Figure 1 and Figure 2 In other embodiments, a filter screen 31 and a guide plate 32 are also included. One end of the filter screen 31 and the guide plate 32 are connected to each other, and the other end of the filter screen 31 and the guide plate 32 are installed inside the water tank 3 to divide the water tank 3 into an upper collection area 33 and a lower convergence area 34. The guide plate 32 is inclined to guide the water on the guide plate 32 to the filter screen 31, and the spraying mechanism 4 sprays the water in the convergence area 34 onto the casting on the conveying mechanism 2. Through the combined structure of the filter screen 31 and the guide plate 32, the internal space of the water tank 3 can be divided into an upper and lower isolated collection area 33 and a convergence area 34. The inclined guide plate 32 uses gravity to guide the liquid in the collection area 33 to the filter screen 31, thereby optimizing the solid-liquid separation path. The filter screen 31 effectively filters large particulate impurities in the liquid through a physical interception mechanism, ensuring that the cleanliness of the coolant entering the convergence area 34 meets the spraying requirements. Furthermore, to ensure the normal operation of the filter screen 31, the impurities on the filter screen 31 need to be cleaned regularly.

[0023] See Figure 1 and Figure 2In other embodiments, a rinsing mechanism 5 is also included, which includes a rain pipe 51, a connecting pipe 52, and a first pump body 53. The rain pipe 51 is installed in the collection area 33 and is located near the end of the guide plate 32 away from the filter screen 31. The rain pipe 51 is arranged along the width direction of the guide plate 32. One end of the connecting pipe 52 is connected to the collection area 34, and the other end of the connecting pipe 52 is connected to the rain pipe 51. The first pump body 53 is installed on the connecting pipe 52.

[0024] In practice, the first pump 53 is started to pump the coolant from the collection area 34 to the deluge pipe 51 through the connecting pipe 52. The deluge pipe 51 sprays water along the width of the guide plate 32 to directly wash away the residual impurities on the surface of the guide plate 32. The impurities move towards the filter screen 31 under the impact of the water flow and are intercepted by the filter screen 31. The washed coolant passes through the filter screen 31 and flows back into the collection area 34. This flushing mechanism 5 achieves directional removal of impurities from the surface of the guide plate 32, and at the same time makes the coolant circulate between the collection area 33 and the collection area 34. This ensures the convenience of centralized treatment of impurities and maintains the cleanliness of the coolant through continuous filtration by the filter screen 31, reducing the risk of clogging of the spraying mechanism 4.

[0025] See Figure 1 and Figure 2 In other embodiments, the spraying mechanism 4 includes: a second pump body 41, a spray pipe 42, and a nozzle 43; one end of the spray pipe 42 is connected to the water tank 3, and the other end of the spray pipe 42 is connected to the nozzle 43; the nozzle 43 is located above the conveying mechanism 2 and faces the casting on the conveying mechanism 2; the second pump body 41 is installed on the spray pipe 42. In specific implementation, the second pump body 41 is started, and the coolant in the water tank 3 is pumped to the nozzle 43 through the spray pipe 42. The nozzle 43 sprays water onto the casting above the conveying mechanism 2 to achieve forced cooling of the high-temperature casting. This spraying mechanism 4 uses the pressure provided by the second pump body 41 to drive the coolant circulation, and the directional spraying of the nozzle 43 ensures that the surface of the casting is uniformly cooled, meeting the requirements of rapid cooling process after casting iron parts are poured, while ensuring the recycling rate of the coolant.

[0026] Furthermore, a filter is installed on the spray pipe 42; the filter installed on the spray pipe 42 can perform secondary filtration of the coolant, effectively reducing the risk of clogging of the impeller of the second pump body 41 and the channels of the nozzle 43 by intercepting fine impurities in the coolant. This filtration structure, together with the filter screen 31 in the water tank 3, forms a graded filtration system. The former performs fine filtration of residual impurities in the spray circuit, while the latter is responsible for intercepting large particulate impurities in the initial coolant. The dual filtration mechanism not only ensures the smooth operation of the spray system, but also extends the service life of the pump body and nozzle 43, reduces the frequency of equipment maintenance, and improves the continuity and stability of the cast iron cooling process.

[0027] See Figure 1 and Figure 2 In other embodiments, multiple nozzles 43 are arranged along the conveying direction of the conveying mechanism 2. The arrangement of multiple nozzles 43 along the conveying direction of the conveying mechanism 2 allows for the formation of a continuous cooling zone through multi-segment spraying, enabling the casting to receive multi-directional water jets during movement, significantly enhancing the cooling effect. This layout design utilizes the spatial distribution characteristics of the nozzle array 43 to ensure that all parts of the casting surface can fully contact the coolant, avoiding localized overheating, while also adapting to the cooling requirements of castings of different lengths, improving the process compatibility of the device.

[0028] Furthermore, the nozzle 43 is ball-jointed to the spray pipe 42. This ball-joint connection allows for flexible adjustment of the spray angle of each nozzle 43, enabling directional cooling of castings of different models and structures. Multi-angle spraying adapts to the complex contours of the casting, ensuring that special areas such as bosses and grooves are covered by coolant, preventing casting deformation or internal stress concentration caused by uneven cooling. This adjustable structure not only meets the diverse cooling needs of castings but also improves cooling efficiency, reduces coolant waste, and enhances the adaptability of the equipment to flexible production scenarios by precisely controlling the spray angle.

[0029] See Figure 1 and Figure 2 In another embodiment, the conveying mechanism 2 is a chain conveyor. Using a chain conveyor as the conveying mechanism 2 allows for the smooth transport of castings through continuous chain transmission, adapting to heavy-duty conditions in high-temperature environments. The rigid support of the chain structure prevents swaying or deformation of the castings during transport. Its open design facilitates direct cooling from above by the spray nozzles 43. Simultaneously, the wear-resistant properties of the chain reduce wear and tear during long-term operation, ensuring the continuity and reliability of casting transport and effectively improving the automation level and production efficiency of the casting cooling process.
