It has limitations in use and cannot meet the use requirements.

[0003] Although the molten iron in the desulfurization station is currently cooled after sampling, the cooling method is usually to cool the high-temperature iron sample directly in water. In addition, since the iron sample is thin and the carbon content of the molten iron is high, many cracks are generated on the surface during the strong cooling process, and the iron sample is often broken during the cooling process, resulting in the need for re-sampling, which greatly reduces production efficiency and increases the labor intensity of the staff and the sampling cost.

[0023] like Figure 1-4 As shown, the utility model provides a cooling device that can improve the crack phenomenon of iron samples, including a cooling box 1, the inner cavity of the cooling box 1 is provided with an air cooling chamber 2 and a coolant channel 3 surrounding the outside of the air cooling chamber 2, and one end of the cooling box 1 is connected with an air inlet pipe 4 for conveying low-temperature gas, the outer wall of the cooling box 1 is connected with a sample injection tube 5, a water inlet pipe 6 and a water outlet pipe 7, the water inlet pipe 6 and the water outlet pipe 7 are respectively arranged at both ends of the cooling box 1, and the water inlet pipe 6 and the water outlet pipe 7 are respectively communicated with the inner cavity of the coolant channel 3, the sample injection tube 5 is located between the water inlet pipe 6 and the water outlet pipe 7, and the sample injection tube 5 is communicated with the inner cavity of the air cooling chamber 2, and a discharge component for placing the iron sample and placing the iron sample into the inner cavity of the air cooling chamber 2 is arranged above the sample injection tube 5.

[0024] In this embodiment, the discharge assembly includes a support frame 8, a cylinder 9 installed on the support frame 8, an L-shaped frame 10 connected to the output end of the cylinder 9, and a sample placing plate 11 connected to one end of the L-shaped frame 10. The sample placing plate 11 is arranged above the sample feeding tube 5. A lifting port 14 is opened through the surface of the support frame 8, and a slider 15 is arranged in the lifting port 14. One end of the L-shaped frame 10 is connected to one side of the slider 15, and the output end of the cylinder 9 is connected to the slider 15.

[0025] Specifically, the cylinder 9 drives the slider 15 and the L-shaped frame 10 to rise and fall, so that after the iron sample is placed on the sample plate 11, the sample plate 11 can enter the air cooling chamber 2 to cool the high-temperature iron sample, and then it is convenient to take out the iron sample after cooling, which is convenient for the staff to clamp the cooled iron sample for subsequent processing, and the support frame 8 is fixedly installed on the connecting seat 19 to ensure the stability of the cylinder 9 and the lifting and lowering stability of the L-shaped frame 10 and the sample plate 11.

[0026] More specifically, guide rails 16 connected to the support frame 8 are respectively provided on both sides of the lifting port 14, and the slider 15 is slidably connected to the guide rails 16. Through the design of the guide rails 16, the slider 15 can ensure its stability when it is lifted and lowered, thereby ensuring the stability of the L-shaped frame 10 and the sample placement plate 11, and a gap is left between the sample placement plate 11 and the inner wall of the sample injection tube 5, and the gap is conducive to the discharge of nitrogen.

[0027] In this embodiment, a first solenoid valve 12 is installed on the air intake pipe 4, and a second solenoid valve 13 is installed on the water inlet pipe 6. Specifically, when the device is in use, the air intake pipe 4 can be externally connected to the delivery pipe of an existing nitrogen production equipment outside, and the flow rate of nitrogen is controlled by the first solenoid valve 12, while the water inlet pipe 6 is externally connected to the delivery pipe of an existing water pump to ensure that cold water enters the coolant channel 3 through the water inlet pipe 6 and is then discharged through the water outlet pipe 7, thereby achieving the effect of cooling the cooling box 1.

[0028] In this embodiment, two fixed supports 17 are provided on the outer wall of the cooling box 1, and the tops of the two fixed supports 17 are respectively connected with movable fasteners 18, and the bottoms of the two fixed supports 17 are simultaneously connected with a connecting seat 19, and the four corners of the connecting seat 19 are respectively provided with mounting holes 20.

[0029] Specifically, by connecting the fixed support 17 and the movable fastener 18 to each other, the cooling box 1 can ensure a certain stability, and then through the mounting hole 20 on the connecting seat 19, the connecting seat 19 can be installed in a designated position as required, so that the device can ensure stability when in use.

[0030] In this embodiment, one end of the air inlet pipe 4, the water inlet pipe 6 and the water outlet pipe 7 are respectively provided with a threaded section. Specifically, the threaded section on the air inlet pipe 4 is used to connect the delivery pipe of the existing nitrogen production equipment, and the threaded sections of the water inlet pipe 6 and the water outlet pipe 7 can be used to connect the existing water circulation refrigeration equipment outside, thereby ensuring that the water source can be reused repeatedly and effectively saving resources.

[0031] The working principle and use process of the utility model are as follows: when in use, the second solenoid valve 13 on the water inlet pipe 6 is in a normally open state, ensuring that the cold water source passes through the coolant channel 3 and then is discharged through the water outlet pipe 7, which is beneficial to the continuous cooling of the cooling box 1. Therefore, the staff will take a sample from the molten iron through the molten iron sampler, and put it on the sample plate 11 through the clamp when the sample forms an iron sample, and then use the cylinder 9 to work, so that when the cylinder 9 contracts, it can drive the L-shaped frame 10 and the sample plate 11 to descend through the slider 15, thereby prompting the high-temperature iron sample on the sample plate 11 to enter the air cooling chamber 2, and then pass through the first solenoid valve 12 is opened, so that the nitrogen delivered by the external nitrogen production equipment can enter the air cooling chamber 2, thereby purging and cooling the high-temperature iron sample. During this period, the air flow is discharged outward through the sampling tube 5. When the iron sample is cooled, the cylinder 9 can be extended and retracted, so that the L-shaped frame 10 can drive the sample plate 11 and the iron sample to rise, which is convenient for the staff to clamp the cooled iron sample for subsequent processing. Therefore, the iron sample does not need to be directly placed in water during the cooling process, which avoids the problem of cracks and breakage on the surface of the iron sample caused by strong cooling. At the same time, it also avoids the problem of subsequent surface moisture treatment of the iron sample after water cooling, thereby simplifying the process.
