[0026] Embodiment
[0027] Refer to Figures 1-5, A heat transfer oil circulation heating structure, including a heating mechanism 1, an oil pipeline 2 and an oil pipeline 2. Inside the heating mechanism 1, there is a heating chamber. The outer wall of the heating chamber is provided with a heating plate, and its interior is a cavity for storing heating oil. The heating chamber is provided with two pipeline connection ports, and both openings are connected to the oil pipeline 2 in a through manner. Among them, the two oil pipelines 2 can be divided into an outlet pipe and an inlet pipe. The outlet pipe is connected to a circulation pump. When the device is operating, the circulation pump can extract the heated heating oil inside the heating chamber, and then output it through the oil pipeline 2 to the designated heating position. The heated oil whose temperature has cooled after heating can be transported back to the heating chamber through the inlet pipe, and then the heating plate on the outer wall of the heating chamber heats the cooled heating oil.
[0028] One side of the heating mechanism 1 is connected to the oil pipeline 2 in a through manner, and the other end of the oil pipeline 2 is connected to an outer pipeline 7 in a through manner. A second flange 14 is fixedly connected to the outside of the heating mechanism 1, and a first flange 8 is fitted on one side of the second flange 14. The inner side of the first flange 8 is fixedly connected to the outer pipeline 7. A protective pipe 5 is fitted on the outside of the outer pipeline 7. One side of the protective pipe 5 is fixedly connected to a connecting sleeve 3, and the other end of the connecting sleeve 3 is fitted with a fixing sleeve 4. The surface of the connecting sleeve 3 is provided with fixing bolts 13. The connecting sleeve 3 is a hollow cylindrical shape with one end open, and the diameter of the inner space of the connecting sleeve 3 is larger than the diameters of the first flange 8 and the second flange 14. The surface of the connecting sleeve 3 is penetrated with screw holes, and the surfaces of the fixing sleeve 4, the first flange 8 and the second flange 14 are all penetrated with screw holes, and the screw holes on the surfaces of the fixing sleeve 4, the first flange 8 and the second flange 14 are all arranged corresponding to the screw holes on the surface of the connecting sleeve 3. Through this design, the staff can put the protective pipe 5 on the outer surface of the outer pipeline 7, and then put the connecting sleeve 3 at one end of the protective pipe 5 on the outside of the first flange 8 and the second flange 14. After the first flange 8 and the second flange 14 are put inside the connecting sleeve 3, the staff can buckle the fixing sleeve 4 on the outside of the second flange 14, and then align the screw holes on the surfaces of the connecting sleeve 3, the fixing sleeve 4, the first flange 8 and the second flange 14. After the screw holes are aligned, the staff can use the fixing bolts 13 to screw into the screw holes to fix the connecting sleeve 3, the fixing sleeve 4, the first flange 8 and the second flange 14, and then fix the protective pipe 5 by fixing the connecting sleeve 3 and the fixing sleeve 4 on the outer surfaces of the first flange 8 and the second flange 14.
[0029] A reinforcing sleeve 6 is fitted and connected to the outer side of the protective pipe 5, and a pressing ring 11 is fixedly connected to the inside of the reinforcing sleeve 6. The reinforcing sleeve 6 is integrally annular, and the reinforcing sleeve 6 is divided into two semi-circular parts. Both semi-circular parts are fitted and connected to the rotating shaft 9, and fixing buckles 10 are fixedly connected to the other sides of both semi-circular parts. A heat insulation ring 12 is fitted and connected to the outer surface of the outer pipe 7. Pressing rings 11 are provided on the inner sides of both parts of the reinforcing sleeve 6, and the pressing rings 11, like the reinforcing sleeve 6, are composed of two semi-circular parts. Before the protective pipe 5 is sleeved on the surface of the outer pipe 7, the staff can spacially sleeve the heat insulation ring 12 on the outer side of the outer pipe 7, and then sleeve the protective pipe 5 on the outer side of the outer pipe 7. After the installation of the protective pipe 5 is completed, the staff can install the reinforcing sleeve 6 on the surface of the protective pipe 5 outside the corresponding heat insulation ring 12 according to the spacing of the previously placed heat insulation rings 12. During the installation of the reinforcing sleeve 6, the staff can open the two fixing buckles 10 to rotate and open the reinforcing sleeve 6 through the rotating shaft 9. After rotation and opening, the reinforcing sleeve 6 is sleeved on the outer side of the protective pipe 5, and then the reinforcing sleeve 6 is fixed on the outer side of the protective pipe 5 by adjusting the installation of the fixing buckles 10. At this time, the pressing ring 11 inside the reinforcing sleeve 6 can cooperate with the heat insulation ring 12 on the surface of the outer pipe 7 to clamp the protective pipe 5, thereby playing a role in strengthening the protective pipe 5.
[0030] Second screw holes are provided on the surfaces of both fixing buckles 10, and buffer pads are fixedly connected to the adjacent surfaces of both fixing buckles 10, and circular holes are provided at the centers of the buffer pads. Through this design, when the staff fixes the two fixing buckles 10 by screwing bolts into the second screw holes, the buffer pads between the two fixing buckles 10 can play the role of gaskets, preventing the two fixing buckles 10 from being too tightly clamped when the bolts are disassembled, which may cause difficulties in disassembly.
[0031] The heat insulation ring 12 is integrally annular, and the overall material of the heat insulation ring 12 is asbestos material. Since asbestos is a high-quality heat insulation material, it can avoid the situation that the inner wall of the protective pipe 5 directly contacts the surface of the outer pipe 7, resulting in the outer pipe 7 being damaged due to long-term direct contact with a high-temperature source.
[0032] Working principle: When the device is operating, the circulating pump can extract the heated oil that has been heated inside the heating chamber, and then output it through the outer pipeline 7 to the designated heating position. The heated oil whose temperature has cooled after heating can be transported back to the heating chamber through the inlet pipeline, and then the heating plate on the outer wall of the heating chamber heats the cooled heated oil. The staff can put the protective pipe 5 on the outer surface of the outer pipeline 7, and then put the connecting sleeve 3 at one end of the protective pipe 5 on the outside of the first flange 8 and the second flange 14. After the first flange 8 and the second flange 14 are sleeved inside the connecting sleeve 3, the staff can buckle the fixing sleeve 4 on the outside of the second flange 14, and then align the screw holes on the surfaces of the connecting sleeve 3, the fixing sleeve 4, the first flange 8 and the second flange 14. After the screw holes are aligned, the staff can use the fixing bolt 13 to screw into the screw holes to fix the connecting sleeve 3, the fixing sleeve 4, the first flange 8 and the second flange 14. Furthermore, by fixing the connecting sleeve 3 and the fixing sleeve 4 on the outer surfaces of the first flange 8 and the second flange 14, the protective pipe 5 is fixed, so that the protective pipe 5 can form a protective layer outside the outer pipeline 7, preventing the staff from accidentally touching the surface of the outer pipeline 7 and getting scalded during the work process.
[0033] The above embodiments are the preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present utility model shall be equivalent replacement methods and are all included in the protection scope of the present utility model.
[0034] In the description of the present utility model, it should be understood that the terms indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
