[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Refer to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present utility model: a rotating shaft of a high-temperature fluid machine, including a mounting plate 1, a bearing housing 2 is fixedly connected to one side of the upper surface of the mounting plate 1, a driving mechanism 3 is fixedly connected to the upper surface of the mounting plate 1, the output end of the driving mechanism 3 is fixedly connected to a rotating shaft body 4, the rotating shaft body 4 is disposed through the inside of the bearing housing 2, a support block 5 is fixedly connected to the upper surface of the mounting plate 1, a lower shell 6 is fixedly connected to the upper surface of the support block 5, an upper shell 7 is slidably connected to the upper surface of the lower shell 6, a liquid storage tank 8 is fixedly connected to the upper surface of the mounting plate 1, a transfer pump 9 is fixedly connected to one side of the outer wall of the liquid storage tank 8, the input end of the transfer pump 9 is fixedly connected to the liquid storage tank 8, a circulation component 10 for cooling the rotating shaft body 4 is installed at the output end of the transfer pump 9, a condenser 11 is fixedly connected to one side of the outer wall of the liquid storage tank 8, a connecting sleeve 12 is sleeved on the outer wall of the rotating shaft body 4, and the connecting sleeve 12 is rotatably connected between the lower shell 6 and the upper shell 7; the circulation component 10 includes a stabilizing pipe 1001, one end of the stabilizing pipe 1001 is fixedly connected to the output end of the transfer pump 9, a spiral pipe 1002 is fixedly connected to one end of the stabilizing pipe 1001, the spiral pipe 1002 is sleeved on the outer wall of the rotating shaft body 4, a stabilizing pipe 1003 is fixedly connected to one end of the spiral pipe 1002, and the stabilizing pipe 1003 is fixedly connected to the input end of the condenser 11;
[0023] Specifically, when the driving mechanism 3 is started, it transmits kinetic energy to the rotating shaft body 4 to ensure the smooth operation of the rotating shaft under the support of the bearing seat 2. At this time, the transfer pump 9 is started to effectively transport the coolant in the liquid storage tank 8 into the inside of the first stabilizing pipe 1001. After being transported by the first stabilizing pipe 1001, the coolant flows into the spiral pipe 1002, which is carried out outside the rotating shaft body 4, so that the rotating shaft body 4 is fully cooled. The used coolant is guided to the condenser 11 through the second stabilizing pipe 1003. After the condenser 11 is started, it further cools the coolant and cools it to an appropriate temperature. The coolant after condensation finally flows back to the liquid storage tank 8, realizing the recycling of the coolant, thereby effectively maintaining the working temperature of the rotating shaft body 4 and ensuring the stability and efficient operation of the mechanical system.
[0024] Referring to Figure 1 、 Figure 2 and Figure 3 As shown in FIGS.
[0025] Specifically, when the rotating shaft body 4 rotates, it drives the second gear 18 to rotate synchronously, and realizes the meshing with the first gear 17 through the movement of the second gear 18. The rotation of the first gear 17 further drives the fan blade 16 on the fixed shaft 15 to rotate. During the rotation of the fan blade 16, the outside cold air is effectively introduced into the transfer hopper 19 through the first dust-proof net 14. The transfer hopper 19 guides the cold air into the connecting pipe 20, and the cold air is transported into the inside of the upper shell 7 through the connecting pipe 20, and then the internal heat is discharged through the second dust-proof net 21. This process not only improves the cooling efficiency of the system, but also ensures the stability and efficient operation of the equipment.
[0026] Working principle: When in use, when the driving mechanism 3 drives the rotating shaft body 4 to transmit kinetic energy, at this time, the rotating shaft body 4 runs stably inside the rotating shaft body 4 through the bearing seat 2. At this time, by starting the transfer pump 9, the coolant in the liquid storage tank 8 is transferred into the first stabilizing pipe 1001 through the transfer pump 9. At this time, it is then transferred into the spiral pipe 1002 through the first stabilizing pipe 1001, so as to make the spiral pipe 1002 outside the rotating shaft body 4 achieve the effect of cooling the rotating shaft body 4. At this time, the used coolant is transferred into the condenser 11 through the second stabilizing pipe 1003. At this time, by starting the condenser 11 again, the condenser 11 can achieve the effect of secondary cooling of the used coolant. At this time, it flows back into the liquid storage tank 8 again, so as to achieve the effect of facilitating the cyclic use of the coolant for cooling;
[0027] Secondly, when the rotating shaft body 4 rotates, it can drive the second gear 18 to rotate synchronously. At this time, through the movement of the second gear 18, the effect of the second gear 18 meshing and rotating with the first gear 17 can be achieved. At this time, through the movement of the first gear 17, the effect of driving the fan blades 16 on the outer wall of the fixed shaft 15 to rotate can be achieved. At this time, the external cold air is transmitted into the transfer hopper 19 through the first dust-proof net 14 by the fan blades 16. At this time, it is then transferred into the connecting pipe 20 through the transfer hopper 19. Through the transmission of the connecting pipe 20, the heat inside the upper shell 7 is discharged through the second dust-proof net 21.
[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
