Description

Technical Field

[0001] The utility model relates to the field of seamless steel pipes, in particular to a high-heat-dissipating precision cold-drawn seamless steel pipe. Background Art

[0002] In industry and manufacturing, seamless steel pipes are widely used in various fluid transport and structural support fields due to their excellent mechanical properties and sealing properties. In particular, in systems requiring efficient heat exchange, such as the chemical, petroleum, power, and refrigeration industries, seamless steel pipes, with their continuous wall structure, can effectively reduce resistance and heat loss during fluid flow, thereby improving the system's thermal efficiency.

The cooling and filtering mechanism is arranged on the left side of the steel pipe body, and a protective mechanism is arranged on the outside of the steel pipe body. The protective mechanism includes a protective sleeve, and a threaded hole is opened at the left end of the protective sleeve. The utility model sets a cooling and filtering mechanism, and cooling water enters the garbage filter frame from the liquid inlet, and the garbage visible to the naked eye is filtered out. Then, the sediment is filtered out through the coarse filter tank, and then enters the fine filter tank. Some scale-forming molecules are adsorbed by activated carbon, and finally pressurized by a booster pump and enter the space formed by the steel pipe body and the protective sleeve from the connecting groove, so as to cool down and dissipate heat for the steel pipe body. At present, most of the equipment dissipates heat from the outside, and the heat dissipation effect is poor. The application of this device effectively avoids the above problems and improves the practicality of the equipment.

[0004] The filter material placed in the above-mentioned filtering device is activated carbon. Long-term filtration will cause the activated carbon to reach a saturated state.

[0029] Specifically, the cooling water pipe is connected to the injection port 13, and the cooling water can be injected into the cavity between the inner tube 1 and the outer shell 2. The flow holes on the connecting piece 12 can make the cooling water fill the cavity between the inner tube 1 and the outer shell 2, thereby achieving comprehensive cooling of the inner tube 1. In order to prevent the cooling water from forming scale inside the cavity when cooling it, activated carbon is installed under the injection port 13 to filter the cooling water. In order to avoid damage to the surface of the outer shell 2, an arc-shaped fixing frame 3 and a protective rod 6 connected thereto are installed on its surface. The protective rod 6 can protect the surface of the outer shell 2 to avoid damage.

[0030] Reference Figure 3 and Figure 4 , wherein the fixing member 8 is provided inside the mounting member 1 5, and the left side of the fixing member 8 is connected to the arc-shaped fixing frame 3 through a spring 9. A plug rod 10 is provided inside the fixing member 8, and the front end of the plug rod 10 is fixedly connected to the rear end of the mounting member 2 7. A baffle is provided at the lower end of the fixing member 8, and a snap-fit ​​groove is provided at the bottom of the plug rod 10, and the baffle is snap-fitted to the inside of the snap-fit ​​groove;

[0031] Specifically, the shell 2 is placed on the inner wall of the arc-shaped fixing frame 3, and then the mounting piece 1 5 and the mounting piece 2 7 on the arc-shaped fixing frame 3 are brought close to each other, and then the fixing piece 8 inside the mounting piece 1 5 is pressed to compress the spring 9 at the bottom, and the groove on the fixing piece 8 that is adapted to the insertion rod 10 is aligned, and then the mounting piece 2 7 is passed through the groove on the fixing piece 8, and then the fixing piece 8 is released. Due to the elastic force of the spring 9, the baffle on the fixing piece 8 is engaged with the engaging groove on the insertion rod 10, so that the mounting piece 2 7 is fixed to the insertion rod 10, thereby connecting the mounting piece 1 5 with the mounting piece 2 7, and fixing the arc-shaped fixing frame 3 and the protective rod 6 to the outer wall of the shell 2.

[0032] Reference Figure 6 and Figure 7 The top of the carrier tube 4 is fixedly connected to a mounting bracket 16, and two inserting plates 14 are provided on the top of the mounting bracket 16.

The surfaces of the inserting plates 14 and the mounting bracket 16 are both provided with fixing grooves, and the inner walls of the fixing grooves are threadedly connected with fixing bolts 15;

[0033] Specifically, by screwing the fixing bolt 15 to separate it from the fixing groove on the mounting frame 16, and then pulling the liquid injection port 13 to remove the plug plate 14 from the mounting groove at the top of the mounting frame 16, and then rotating the mounting frame 16 to remove the carrier tube 4 from the inside of the connecting pipe 11, the activated carbon inside the carrier tube 4 can be replaced, and then the replaced carrier tube 4 is installed in the connecting pipe 11, and then the plug plate 14 on the liquid injection port 13 is inserted into the mounting groove on the mounting frame 16, so that the plug plate 14 is aligned with the fixing groove on the mounting frame 16, and then the fixing bolt 15 is screwed into the fixing groove. After tightening it, cooling water can be injected into the space between the inner tube 1 and the outer shell 2 through the liquid injection port 13 to cool the inner tube 1.

[0034] Working principle: Connect the cooling water pipe to the liquid injection port 13, and the cooling water can be injected into the cavity between the inner tube 1 and the outer shell 2. The flow holes on the connecting piece 12 can make the cooling water fill the cavity between the inner tube 1 and the outer shell 2, so as to achieve comprehensive cooling of the inner tube 1. In order to prevent the cooling water from forming scale inside the cavity when cooling it, activated carbon is installed under the liquid injection port 13 to filter the cooling water. However, the activated carbon will reach saturation after filtering it for a long time, thereby reducing the filtering effect. It is separated from the fixing groove on the mounting frame 16 by tightening the fixing bolt 15, and then the plug 14 is removed from the mounting groove on the top of the mounting frame 16 by pulling the liquid injection port 13, and then Rotate the mounting frame 16 to remove the carrier tube 4 from the inside of the connecting tube 11, so that the activated carbon inside the carrier tube 4 can be replaced. In order to avoid damage to the surface of the shell 2, the shell 2 is placed on the inner wall of the arc-shaped fixing frame 3, and then the mounting piece 1 5 and the mounting piece 2 7 on the arc-shaped fixing frame 3 are close to each other. Then, by pressing the fixing piece 8 inside the mounting piece 1 5, the spring 9 at the bottom is compressed, and the groove on the fixing piece 8 that is adapted to the insertion rod 10 is aligned. After the mounting piece 2 7 is passed through the groove on the fixing piece 8, the fixing piece 8 is released. Due to the elastic force of the spring 9, the baffle on the fixing piece 8 is engaged with the engaging groove on the insertion rod 10, thereby fixing the arc-shaped fixing frame 3 and the protective rod 6 to the outer wall of the shell 2.
