Description

Technical Field

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

[0002] Ductile iron has superior mechanical properties compared to gray cast iron, and is similar to steel. It can replace cast steel and forged steel in manufacturing various parts with high loads, complex stresses, and high wear resistance. Cooling water plays a crucial role in the production of ductile iron parts. Cooling water not only regulates the cooling rate and temperature of the castings but also, to a certain extent, ensures the quality and performance of the castings. A patent with publication number CN214148470U discloses a rapid cooling device for ductile iron production. In use, the ductile iron is placed inside a cooling chamber for cooling. Then, a water pump is turned on via a control panel, drawing water from the cooling chamber and pumping it into an inlet chamber. The coolant inside the inlet chamber then carries away the heat from the water in the pipes, and finally, the water is sprayed out through nozzles. The current method of cooling ductile iron involves rapidly dissipating heat, filtering impurities from the ductile iron through a filter screen, and collecting the water in a collection chamber. When water needs to be changed, the outlet is opened to drain the water from the cooling chamber. However, this method is wasteful of water resources and cannot rapidly cool the water while cooling, resulting in poor cooling effect. Therefore, a cooling device for ductile iron production is designed that allows for the repeated use of cooling water, reducing water waste, and rapidly circulates the cooling water during cooling to further improve the cooling effect of ductile iron parts. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a cooling device for ductile iron production. The cooling water can be reused repeatedly, reducing water waste. At the same time, the cooling water is rapidly circulated during cooling, further improving the cooling effect of ductile iron parts.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for ductile iron production, comprising a cooling tank, a chiller, and a water pump. The interior of the cooling tank is divided into an inner and outer cooling chamber and an overflow chamber by a circular partition. The top of the circular partition is lower than the height of the cooling tank. A stirring mechanism and a protective filter screen are arranged sequentially from bottom to top at the bottom of the cooling chamber. The stirring mechanism is rotatably connected to the bottom of the cooling tank, and the protective filter screen is connected to the cooling tank. The input end of the chiller is connected to the bottom of the overflow chamber through a water inlet pipe, and the output end of the chiller is connected to the input end of the water pump through a water blowing pipe. The output end of the water pump is fixedly connected to the bottom of the cooling chamber through a water return pipe, and a slag filter screen is provided at the top of the overflow chamber.

[0007] Preferably, the filter screen is configured as an inverted cone shape and is fixedly connected to the top of the inner wall of the cooling tank and the outer wall of the circular partition, respectively, and a certain filter screen storage gap is provided between the filter screen and the top of the circular partition, and the protective screen is configured as an arc shape.

[0008] Preferably, a drive motor for driving the stirring mechanism to rotate is fixedly installed at the bottom of the cooling tank.

[0009] Preferably, it also includes a base plate, on which the cooling tank, water pump and chiller are all fixedly mounted.

[0010] Preferably, the fixed connection position between the return water pipe and the bottom of the cooling chamber is located below the stirring mechanism.

[0011] Preferably, the inner bottom of the cooling chamber is lower than the inner bottom of the overflow chamber.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a cooling device for ductile iron production, which has the following beneficial effects:

[0014] This cooling device for ductile iron production can be filled with cooling water to cool ductile iron parts. When the ductile iron parts need cooling, they can be placed into the cooling chamber from the top. The cooling water at the top first exchanges heat with the ductile iron parts, while simultaneously overflowing into the overflow chamber until the ductile iron parts are completely immersed. Through the cooperation of a chiller and a water pump, the high-temperature cooling water in the overflow chamber is cooled, and then pressurized by the water pump and sent into the cooling chamber from the bottom, thus lowering the temperature at the top. High-temperature cooling water enters the overflow chamber, and this process repeats until the ductile iron casting is cooled to a certain temperature. A stirring mechanism further agitates the cooling water during the cooling process, improving the cooling effect. A protective filter prevents damage to the stirring mechanism from the ductile iron casting. A slag filter prevents impurities in the cooling water from entering the chiller. This cooling device for ductile iron production allows for repeated use of the cooling water, reducing waste. Simultaneously, the rapid circulation of cooling water during cooling further enhances the cooling effect on the ductile iron casting. Attached Figure Description
