Description

Technical Field

[0001] This utility model relates to the field of casting waste cooling, and in particular to a rapid cooling device for a medium-frequency furnace for melting iron in casting waste. Background Technology

[0002] In the field of casting waste treatment, the high-temperature waste generated by melting iron induction furnaces needs to be rapidly cooled to improve recycling efficiency. Traditional cooling devices often use single air cooling or water cooling methods, which have problems such as low cooling efficiency, cracking and deformation of castings due to excessively rapid cooling, and uneven cooling that easily leads to a large amount of residual heat inside the waste. At the same time, most devices have fixed structures, cumbersome waste loading and unloading, and cannot be flexibly adapted to different specifications of induction furnaces, making maintenance difficult. In addition, existing devices lack intelligent temperature control systems, making it difficult to accurately control the cooling rhythm, which not only affects the quality of castings but also causes energy waste. Therefore, there is an urgent need for a new type of device that combines efficient cooling, convenient operation, and precise temperature control to meet the needs of modern industry for casting waste treatment.

[0003] A search revealed CN211233982U, which discloses a rapid cooling device for an intermediate frequency furnace for melting iron in casting scrap, including the furnace body. This rapid cooling device, through an inlet pipe, introduces cold water from a cold water tank into the furnace body under the action of a first water pump, cooling the components inside the furnace body. The cooled, high-temperature water is then discharged from the outlet pipe under the action of a second water pump. As the water passes through a spiral tube, the copper spiral tube absorbs the heat from the high-temperature water. The presence of several heat dissipation fins on the outside of the spiral tube effectively increases the contact area between the spiral tube and the air, accelerating heat dissipation and increasing the cooling rate of the high-temperature water. This provides initial cooling for the water discharged from the furnace body. Furthermore, the spiral shape of the tube increases the time the water flows within it, extending the cooling time and enhancing the cooling effect, thus achieving a superior cooling performance.

[0004] While existing technologies can achieve a certain cooling effect during use, they suffer from drawbacks: the lack of efficient and uniform cooling structures and convenient modular loading and unloading designs. In view of this, we propose a rapid cooling device for a medium-frequency furnace for melting iron in casting scrap, which solves the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a rapid cooling device for a medium-frequency furnace for melting iron in casting waste.

[0006] The technical solution of this utility model is as follows: A rapid cooling device for a medium-frequency furnace for melting iron in casting waste includes a first shell, a second shell, and guide rails. Guide rails are provided inside both the first and second shells. The first shell is provided with multiple fans and multiple guide plates. The guide plates are located on one side of the fans and face the guide rails. The guide plates guide the airflow from the fans to the guide rails at an angle. The guide rails are arranged in a multi-layer circumferential array on the inner walls of the first and second shells.

[0007] When using the rapid cooling device for a medium-frequency furnace for melting iron casting scrap in this solution, place the device on a stable workbench and ensure equipment stability using the base. Connect the external cooling water pipe using the water inlet and fill the water tank with cooling water to prepare for the subsequent water cooling stage. Hold the handle of the second shell and separate it from the first shell to open the cooling device. Place the casting scrap into the space formed by the first and second shells. Utilizing the quick-connectable double-shell structure, quickly combine the second shell with the first shell using the handle to form a closed cooling space, preventing cooling airflow leakage and facilitating subsequent efficient cooling. Start the fan, and the multi-layered circumferential array of guide rails and baffles begins to function. The air blown by the fan is guided by the baffles, changing the airflow direction and tilting it towards the guide rails, so that the airflow evenly covers the casting scrap along the circumference. The multi-layer array design of the guide rail allows airflow to contact the casting scrap from different angles, achieving all-round, no-dead-angle air cooling. This quickly removes heat from the surface of the casting scrap, providing initial cooling while preventing quality problems caused by excessively rapid local cooling. A temperature sensor on the inner wall of the first housing monitors the temperature in real time and transmits the signal to the controller. When the casting scrap is cooled to near the preset intermediate temperature threshold by air cooling, the controller activates the water pump. Cooling water from the tank is sprayed onto the casting scrap through nozzles, providing additional water cooling on top of air cooling, further rapidly reducing the temperature of the casting scrap and completing the entire cooling process. After cooling, the handle is grasped again to separate the second housing from the first housing and quickly remove the casting scrap. The device's through-slot design facilitates the discharge of hot air and water vapor generated during the cooling process.

[0008] Preferably, a water tank is fixedly connected to one side of the outer wall of the first housing, a water inlet is fixedly connected to one side of the outer wall of the water tank, and a nozzle is fixedly connected to the other side of the outer wall of the water tank. The water tank is used to store cooling water.

[0009] Preferably, a controller and a water pump are fixedly connected to the outer wall of the water tank, and the controller is connected to the water pump, temperature sensor and fan through a circuit.

[0010] Preferably, a temperature sensor is fixedly connected to the inner wall of the first housing. The temperature sensor detects the temperature in real time and converts it into an electrical signal, which is then transmitted to the controller.

[0011] Preferably, a second housing is provided on one side of the first housing, and the cross-sections of the first housing and the second housing are combined to form a circle. A handle is fixedly connected to the outer wall of one side of the second housing, and the first housing and the second housing can be quickly assembled or disassembled by moving the second housing through the handle.

[0012] Preferably, both the first housing and the second housing are provided with multiple through slots, which provide channels for airflow.

[0013] Preferably, a base is fixedly connected to the lower outer wall of both the first housing and the second housing, and the base serves to increase stability.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model utilizes a multi-layered circular array of guide rails and guide plates to ensure that the air blown by the fan evenly covers the casting waste along the circumference. Compared with the traditional single air cooling method, this significantly improves heat exchange efficiency and ensures uniform cooling of all parts of the casting. The step-by-step cooling strategy of first air cooling and then water cooling, through precise control by temperature sensors and controllers, can not only avoid quality problems such as cracks and deformation caused by excessive cooling of the casting, but also promptly start water cooling after the air cooling reaches the appropriate temperature to quickly reduce residual heat, significantly shortening the overall cooling cycle and meeting the high efficiency and reliability requirements of casting waste treatment in industrial production.

[0016] Second, based on the first beneficial effect, the quick-assembly double-shell design further enhances the practicality of the device. The first and second shells can be quickly assembled or disassembled via handles. When assembled, they form a closed cooling space, effectively preventing airflow leakage and enhancing the effects of air and water cooling. When disassembled, they facilitate the quick loading and unloading of casting scrap, significantly improving operational efficiency. This modular structure not only facilitates daily maintenance and repair of the equipment but also flexibly adapts to scrap from medium-frequency furnaces of different sizes. Furthermore, the through-slot design on the shells ensures efficient airflow during cooling, further optimizing cooling performance and achieving a dual breakthrough in structural innovation and functional enhancement.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Please see Figures 1-4 As shown, this embodiment is a rapid cooling device for a medium-frequency furnace for melting iron casting scrap, including a first shell 11 and a guide rail 2. The first shell 11 is provided with the guide rail 2, multiple fans 10, and multiple guide plates 1. The guide plates 1 are located on one side of the fans 10 and face the guide rail 2. In use, the casting scrap is placed in the space formed by the first and second shells 12. The fans 10 are started, and the air blown out by the fans 10 is guided by the guide plates 1, changing the air direction and tilting it towards the guide rail 2. The airflow carries away the heat of the casting scrap, performing preliminary air cooling. The multi-layered circular array of guide rails 2 can make the airflow cover the casting scrap more evenly, improving the air cooling efficiency.

[0030] Example 2

[0031] Please see Figures 1-4As shown, this embodiment, based on embodiment 1, further includes: a water tank 6 fixedly connected to one outer wall of the first housing 11, a water inlet 5 fixedly connected to one outer wall of the water tank 6, and a nozzle 9 fixedly connected to the other outer wall of the water tank 6. In use, the water inlet 5 is connected to an external pipe to inject cooling water into the water tank 6; the temperature sensor 8 on the inner wall of the first housing 11 converts the temperature signal into an electrical signal and transmits it to the controller 3. When the casting scrap is cooled by air cooling to near the preset intermediate temperature threshold, the controller 3 controls the water pump 4 to start, spraying the cooling water in the water tank 6 onto the casting scrap through the nozzle 9. Water spraying is performed on the basis of air cooling to further and quickly reduce the temperature of the casting scrap; the air cooling method first allows the casting scrap to cool down slowly, preventing the casting from cracking, deforming and other quality problems caused by excessively rapid cooling.

[0032] A controller 3 and a water pump 4 are fixedly connected to the outer wall of the water tank 6. During use, the temperature sensor 8 monitors the temperature inside the first housing 11 in real time and continuously converts the temperature signal into an electrical signal, which is then transmitted to the controller 3. Based on a preset temperature threshold, the controller 3 first controls the fan 10 for air cooling, and then controls the water pump 4 to start spraying water for cooling once the temperature drops to the set value.

[0033] A temperature sensor 8 is fixedly connected to the inner wall of the first housing 11. During use, the temperature sensor 8 continuously collects temperature data inside the first housing 11 and promptly feeds back temperature changes to the controller 3.

[0034] A second housing 12 is provided on one side of the first housing 11. The cross-sections of the first housing 11 and the second housing 12 are combined to form a circle. A handle 7 is fixedly connected to the outer wall of one side of the second housing 12. In use, the second housing 12 can be quickly combined or separated from the first housing 11 through the handle 7. When combined, a closed space is formed, which improves the effect of air cooling and water spray cooling. When separated, it is convenient to quickly load and unload casting waste, which improves work efficiency.

[0035] Both the first housing 11 and the second housing 12 are provided with multiple through slots 13. In use, the through slots 13 provide a flow channel for cooling airflow, allowing the air blown out by the fan 10 to flow smoothly inside the housing. At the same time, it is also convenient to discharge the hot air and water vapor generated during the cooling process, ensuring the airflow inside the housing and maintaining a good cooling environment. When water is sprayed for cooling, the through slots 13 can help dissipate water vapor and prevent the accumulation of internal moisture.

[0036] The lower outer walls of the first housing 11 and the second housing 12 are both fixedly connected to the base 14. During use, the base 14 provides stable support for the entire cooling device, ensuring that the device can maintain balance even if the fan 10 is running and the water pump 4 is working and vibrating during air cooling and water spray cooling, thus preventing the device from shifting or tipping over and ensuring the safety and stability of the cooling operation.

[0037] Instructions for Use: When using this device, place it on a stable workbench and ensure stability using the base 14. Connect the external cooling water pipe using the water inlet 5 and fill the water tank 6 with cooling water to prepare for the subsequent water cooling stage. Hold the handle 7 of the second housing 12 to separate it from the first housing 11 and turn on the cooling device. Place the casting scrap into the space formed by the first and second housings 12. Utilizing the quick-connectable double-housing structure, quickly assemble the second housing 12 with the first housing 11 using the handle 7 to form a closed cooling space, preventing cooling airflow leakage and facilitating subsequent efficient cooling. Start the fan 10, and the multi-layered circumferential array of guide rails 2 and baffles 1 begin to function. The air blown by the fan 10 is guided by the baffles 1, changing the airflow direction and tilting it towards the guide rails 2, so that the airflow evenly covers the casting scrap along the circumference. The multi-layer array design of the guide rail 2 allows airflow to contact the casting scrap from different angles, achieving all-round, no-dead-angle air cooling, quickly removing heat from the surface of the casting scrap for initial cooling, while avoiding quality problems caused by excessively rapid local cooling of the casting; the temperature sensor 8 on the inner wall of the first housing 11 monitors the temperature in real time and transmits the signal to the controller 3; when the casting scrap is cooled to near the preset intermediate temperature threshold by air cooling, the controller 3 controls the water pump 4 to start, and the cooling water in the water tank 6 is sprayed onto the casting scrap through the nozzle 9, performing water spray cooling on the basis of air cooling, further rapidly reducing the temperature of the casting scrap, and completing the entire cooling process; after cooling is completed, the handle 7 is grasped again to separate the second housing 12 from the first housing 11 and quickly remove the casting scrap; the through slot 13 of the device is designed to facilitate the discharge of hot air and water vapor generated during the cooling process.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
