[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] In a specific embodiment, as Figure 1 - Figure 2 shown;

[0029] Inner steel pipe 1 and cooling cavity 2 opened on the outer side of inner steel pipe 1;

[0030] The outer side of inner steel pipe 1 is provided with outer steel pipe 3, and outer steel pipe 3 is located on the outer side of cooling cavity 2. And the lower end of outer steel pipe 3 is fixedly installed with docking pipe 4. The lower end of docking pipe 4 is provided with cooling pipe 5. And the end of cooling pipe 5 far from docking pipe 4 is fixedly installed with cooling box 6. The upper end of outer steel pipe 3 is fixedly installed with drain pipe 23. The lower end of cooling box 6 is higher than the upper end of drain pipe 23.

[0031] When using this automatically cooled stainless steel pipe, it is necessary to install this stainless steel pipe at the working position, and install cooling box 6 on the outer side of cooling pipe 5 through an external support. After that, the automatic cooling of this stainless steel pipe can be realized;

[0032] During this process, the water flow inside cooling box 6 will enter the inside of docking pipe 4 through cooling pipe 5. After that, this water flow will enter the inside of cooling cavity 2. At this time, the high-temperature water flow inside cooling cavity 2 will be discharged through drain pipe 23, thus completing the cooling process of this stainless steel pipe. And according to the situation that the high-temperature liquid inside the liquid will move upward, it is convenient for the high-temperature water flow inside cooling cavity 2 to be discharged. And the water flow inside cooling cavity 2 will absorb the heat inside it through inner steel pipe 1, completing the automatic cooling process of this stainless steel pipe.

[0033] In one specific embodiment, as Figure 1 - Figure 5 shown;

[0034] A heat conducting member 8 is fixedly installed on the outer side of the inner pipe 1 of the steel pipe, and a fixing frame 7 is fixedly installed on the outer side of the outer pipe 3 of the steel pipe. The fixing frame 7 is in close contact with the heat conducting member 8, and a temperature-changing cavity 9 is formed inside the fixing frame 7;

[0035] A moving block 10 is slidably installed inside the temperature-changing cavity 9. One end of the moving block 10 away from the temperature-changing cavity 9 is fixedly installed with a connecting rod 11, and one end of the connecting rod 11 away from the moving block 10 is fixedly installed with a sealing plate 12. Meanwhile, the sealing plate 12 is located between the butt joint pipe 4 and the cooling pipe 5;

[0036] Two groups of sliders 13 are fixedly installed on the outer side of the moving block 10, and balls 14 are nested inside the sliders 13.

[0037] During the use of the stainless steel pipe, the high-temperature conveying medium inside the inner pipe 1 of the steel pipe will transfer heat to the water flow inside the cooling cavity 2 through heat conduction. The water flow inside the cooling cavity 2 will absorb the heat inside the inner pipe 1 of the steel pipe, and the copper heat conducting member 8 will transfer the heat inside the inner pipe 1 of the steel pipe and the cooling cavity 2 to the fixing frame 7. At this time, the temperature inside the fixing frame 7 will rise;

[0038] At this time, the air pressure inside the temperature-changing cavity 9 will increase and cause the moving block 10 to slide inside the temperature-changing cavity 9. During the sliding process of the moving block 10, it will push the sealing plate 12 to slide between the butt joint pipe 4 and the cooling pipe 5 through the connecting rod 11. During the sliding process of the sealing plate 12, the butt joint pipe 4 and the cooling pipe 5 will be in an open state. Then, the low-temperature water flow inside the cooling box 6 can enter the inside of the cooling cavity 2 to complete the cooling process. During the sliding process of the sealing plate 12, it will slide inside the cooling pipe 5 through the slider 13, and the balls 14 inside the slider 13 will roll to reduce the friction force received by the sealing plate 12;

[0039] When the low-temperature water flow inside the cooling box 6 enters the inside of the cooling cavity 2, it will cool the inner pipe 1 of the steel pipe and the medium conveyed inside it. After the cooling is completed, the temperature inside the temperature-changing cavity 9 will decrease, which will cause the air pressure inside the temperature-changing cavity 9 to decrease, and then cause the moving block 10 and the sealing plate 12 to move to the initial position. Thus, the automatic cooling process of the stainless steel pipe is completed, effectively improving the convenience of cooling the stainless steel pipe.

[0040] On the basis of the above embodiments, as Figure 1 - Figure 2 and Figure 6 shown;

[0041] Two sets of fixing members 25 are fixedly installed inside the drain pipe 23, and two sets of filter plates 26 are arranged inside the drain pipe 23, and the filter plates 26 are located between the two sets of fixing members 25. At the same time, a moving cylinder 15 is fixedly installed on the outer side of the left filter plate 26. A fixing cylinder 16 is slidably installed inside one end of the moving cylinder 15 away from the left filter plate 26, and one end of the fixing cylinder 16 away from the moving cylinder 15 is fixedly connected to the right filter plate 26. A return spring 17 is arranged between the moving cylinder 15 and the fixing cylinder 16;

[0042] A fixing block 18 is fixedly installed inside the drain pipe 23, and a blocking member 20 is slidably installed inside the fixing block 18. A contact rod 22 is fixedly installed at one end of the fixing block 18 away from the blocking member 20. A support spring 21 is sleeved on the outer side of the moving rod 19, and the support spring 21 is located between the fixing block 18 and the contact rod 22;

[0043] The lower end of the drain pipe 23 is threadedly installed with a sewage tank 24, and the upper end of the sewage tank 24 is in close contact with the contact rod 22, and the contact rod 22 is slidably connected to the lower end of the drain pipe 23.

[0044] When using this automatic cooling stainless steel pipe, the high-temperature water flow inside the cooling cavity 2 will be discharged through the drain pipe 23. During the discharge process of the high-temperature water flow, impurities or scale in the water flow will be discharged synchronously. During the flow of the high-temperature water flow, it will impact the left filter plate 26, and the left filter plate 26 will move to the right and there will be a gap between it and the left fixing member 25. At this time, the scale or impurities will enter between the two sets of filter plates 26 through this gap, and the impurities or water quality will move downward at this time and enter the inside of the sewage tank 24 through the gap between the drain pipe 23 and the blocking member 20;

[0045] During the movement of the left filter plate 26, the moving cylinder 15 will slide on the outer side of the fixing cylinder 16. At this time, the return spring 17 will contract, and after the water flow in the cooling cavity 2 stops flowing, the return spring 17 will expand and make the left filter plate 26 seal with the left fixing member 25;

[0046] And after scale or impurities enter the sewage tank 24 made of transparent material, it can be directly observed whether the scale or impurities inside the sewage tank 24 need to be cleaned;

[0047] During the process of cleaning the scale or impurities inside the sewage discharge tank 24, it is necessary to rotate the sewage discharge tank 24 and separate it from the liquid discharge pipe 23. During the process of the sewage discharge tank 24 moving away from the liquid discharge pipe 23, the contracted support spring 21 will expand and cause the contact rod 22 to move downward. The downward movement of the contact rod 22 will drive the blocking member 20 to move downward through the movement rod 19, so that the blocking member 20 seals with the liquid discharge pipe 23, avoiding the liquid inside the liquid discharge pipe 23 from discharging after the sewage discharge tank 24 is separated from the liquid discharge pipe 23. Thus, the sewage discharge process of the liquid discharge pipe 23 is completed, effectively ensuring the stability of the temperature reduction of the stainless steel pipe and increasing the overall practicability.
