Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0025] like Figure 1 As shown, the utility model provides a molten steel sample cooling and drying device, comprising:

[0026] The liquid cooling tank 6 and the air cooling tank 4 are respectively provided with a first screen 7 and a second screen 3. The upper part of the liquid level in the liquid cooling tank 6 is connected to the upper part of the first screen 7 in the air cooling tank 4. The first screen 7 is connected to the liquid cooling tank 6 by a lifting component.

[0027] The air supply pipeline is connected to the lifting component and the air cooling groove 4 and is used to drive the lifting component and supply cooling air to the air cooling groove 4.

[0028] Specifically, in order to solve the problem in the prior art that it is difficult to salvage molten steel samples after cooling and the surface moisture needs to be wiped off manually, the molten steel sample cooling and drying device provided by the utility model has a liquid cooling tank 6 and an air cooling tank 4. The combination of liquid cooling and air cooling can not only improve the cooling efficiency, but also dry the molten steel sample during the air cooling process, eliminating the need for manual wiping. The first screen 7 is connected to the liquid cooling tank 6 through a lifting component. Driven by the lifting component, the molten steel sample immersed below the liquid level in the liquid cooling tank 6 can be salvaged, and the liquid cooling tank 6 is connected to the air cooling tank 4, so that the molten steel sample can enter the air cooling tank 4 for air cooling and air drying. The salvaging and drying of the molten steel sample do not require manual operation, which reduces the difficulty of salvaging the molten steel sample and reduces the manual workload.

[0029] Optionally, the first screen 7 is in sheet shape, and an end of the first screen 7 away from the air-cooling groove 4 is higher than an end thereof close to the air-cooling groove 4 .

[0030] Specifically, the first screen 7 is tilted so that after the molten steel sample is salvaged through the first screen 7 , the molten steel sample can automatically roll toward the air cooling tank 4 and enter the air cooling tank 4 for air cooling.

[0031] Optionally, the liquid cooling tank 6 is connected to the air cooling tank 4 through the slide 5 , and one end of the slide 5 connected to the liquid cooling tank 6 is higher than the other end thereof connected to the air cooling tank 4 .

[0032] Specifically, the slide 5 can accommodate the molten steel sample to pass through. The molten steel sample rolls and slides due to the inclined first screen 7, and enters the air-cooling tank 4 after the inclined sliding.

[0033] Optionally, the lifting component is a cylinder 8 , one end of the cylinder 8 is fixed to the bottom of the liquid cooling tank 6 , and the other end of the cylinder 8 is connected to the first screen 7 .

[0034] Specifically, under the action of gas supplied by the gas supply pipeline, the cylinder 8 can extend the telescopic end to drive the first screen 7 to rise and salvage the molten steel sample.

[0035] Optionally, a first valve 11 is provided on the air supply pipeline connected to the cylinder 8 , and a second valve 16 is provided on the air supply pipeline connected to the air cooling tank 4 .

[0036] Specifically, the first valve 11 and the second valve 16 are used to control the operation of the cylinder 8 and the air cooling tank 4 respectively.

[0037] Optionally, the first valve 11 is a foot-operated delayed closing valve.

[0038] Specifically, the first valve 11 is a foot-operated delayed closing valve, which is easy to operate. The delayed closing function allows the first screen 7 to rise and then fall after a period of time.

[0039] Optionally, a linkage mechanism is connected between the first screen 7 and the second valve 16, and the linkage mechanism can drive the second valve 16 to open when the first screen 7 is in a raised state.

[0040] Specifically, under the action of the linkage mechanism, after the first screen 7 is raised, the second valve 16 can be driven to open without separate operation, thereby realizing the automatic connection of the liquid cooling and air cooling processes. In conjunction with the delayed closing of the first valve 11, the second valve 16 can be closed after a period of time, thereby completing the automatic control of the air cooling time.

[0041] Optionally, the linkage mechanism includes:

[0042] A support guide component, one end of which is connected to the outer wall of the liquid cooling tank 6;

[0043] The linkage rod 12 has an upper end in an inverted U shape, the upper end of the linkage rod 12 is connected to the first screen 7, the lower end of the linkage rod 12 is connected to the second valve 16, and the middle part of the linkage rod 12 is slidably fitted with the other end of the supporting guide component.

[0044] Specifically, the supporting guide component supports and guides the linkage rod 12, and the guide can be a vertical guide. The upper end of the linkage rod 12 is fixedly connected to the first screen 7, and is driven to rise and fall by the first screen 7. When it rises, the lower end of the linkage rod 12 drives the operating part of the second valve 16 to operate, and the second valve 16 is opened. As the first screen 7 falls, the linkage rod 12 falls, and then the second valve 16 is closed.

[0045] In this embodiment, two support guide components are provided, arranged one above and one below, namely the first support guide component 13 and the second support guide component 15. One end of the support guide component is rod-shaped and connected to the liquid cooling tank 6, and the other end has a guide sleeve, which is slidably sleeved on the outside of the linkage rod 12.

[0046] Furthermore, it can also include a return spring 14, which can be arranged in the guide sleeve, with its two ends respectively connected to the first limit part in the guide sleeve and the second limit part outside the linkage rod 12, for applying a downward force to the linkage rod 12, causing it to move downward and close the second valve 16.

[0047] Optionally, a gas distribution component 2 is provided below the second screen 3 in the air-cooling trough 4 , and a gas supply pipeline connected to the air-cooling trough 4 is connected to the lower end of the gas distribution component 2 .

[0048] Specifically, the gas distribution component 2 can be a trumpet-shaped or porous gas distribution plate, etc., which is used to distribute the gas as evenly as possible so that the gas can be blown as evenly as possible from bottom to top on the horizontal section of the air-cooling trough 4 to the molten steel sample on the upper side of the second screen 3.

[0049] Optionally, a compressed air source is further included, and the air supply pipeline is connected to the compressed air source.

[0050] Specifically, the compressed gas source may be an air compressor or a compressed gas container, such as an argon gas cylinder.

[0051] In this embodiment, the gas supply pipeline may include a first gas supply pipeline 1 and a second gas supply pipeline 10 , which are connected to the gas distribution component 2 and the gas cylinder 8 respectively.

[0052] In summary, when the molten steel sample cooling and drying device provided by the present invention is used, a cooling and drying process of the molten steel sample is taken as an example: in the initial state, the first screen 7 is located below the cooling water level 9, and the molten steel sample is directly placed in the liquid cooling tank 6 after being taken out. After cooling for about two minutes, the operator steps on the first valve 11 with his foot, and the first valve 11 is closed after a delay of two minutes, providing an upward power for the cylinder 8, so that the first screen 7 rises, and its lowest point gradually rises to be flush with the lowest point on the right side of the slide 5. At this time, the cylinder 8 stops rising, and the tilted first screen 7 causes the molten steel sample to roll into the air cooling tank 4, so that the molten steel sample is in the second Above the screen 3; during the rising process of the first screen 7, the highest point on the right side will drive the linkage rod 12 to rise, and the linkage rod 12 rises to open the second valve 16, and introduces argon gas into the air-cooling tank 4 to further cool and dry the molten steel sample. After the first valve 11 delays for two minutes to close the argon gas, the first screen 7 automatically falls back to the initial position below the cooling water level 9. During the descent of the first screen 7, the linkage rod 12 closes the second valve 16 under the resetting action of the spring 14. After the second valve 16 is closed, the molten steel sample is taken out and sent to the laboratory for testing. The device completes the automatic cooling and air-drying process of the molten steel sample.

[0053] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
