Technical Field

[0001] This utility model belongs to the technical field of heat exchange systems, specifically relating to a circulating heat exchanger for a thermal oil furnace. Background Technology

[0002] A thermal oil circulating heat exchanger is a highly efficient heat transfer device. It uses thermal oil as the heat transfer medium and achieves liquid-phase circulation of the medium with the forced action of a hot oil circulating pump, thereby efficiently delivering heat energy to various thermal equipment. After completing the heat transfer, the thermal oil returns to the heating furnace for reheating, and so on, continuously providing stable heat energy for the production process.

[0003] However, during the installation of the thermal oil heater, after it is placed on the ground, its movement requires restarting the hoisting machine for control and fine-tuning, which increases the overall installation time. Utility Model Content

[0018] Compared with the prior art, this utility model provides a circulating heat exchanger for a thermal oil furnace, which has the following beneficial effects:

[0019] By installing rollers, the installation position of the thermal oil heater can be fine-tuned during installation, once it is in contact with the ground. This eliminates the need to wait for the preparation and operation of the hoisting machine. Since the hoisting machine is no longer relied upon for fine-tuning, the time spent on position adjustments during the entire installation process is significantly reduced. This increased installation efficiency directly accelerates the progress of the entire project. For projects with tight schedules, the thermal oil heater is a critical piece of equipment, and its installation progress directly affects the subsequent equipment commissioning and the overall project delivery time. Using rollers to quickly fine-tune the furnace's installation position allows the project to proceed as planned, avoiding a series of chain reactions caused by installation delays. Furthermore, in locations with limited installation space, such as basements or equipment rooms, where the hoisting machine may not be able to operate, operators can manually push the furnace within the confined space to make precise position adjustments, ensuring the furnace is installed in the most suitable location.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1-4 The thermal oil furnace circulating heat exchanger shown includes a furnace body 1 and an electric heater 12 installed inside the furnace body 1.

[0027] An oil return pipe 2 is provided on the upper circular outer wall of the furnace body 1 near the left side to guide the cooled oil back into the furnace body 1.

[0028] A guide pipe 5 is provided on the upper circular outer wall of the furnace body 1 near the right side;

[0029] An oil outlet pipe 4 is fixedly connected to the upper outer wall of the guide pipe 5 to guide high-temperature oil to the required equipment. A suction pump 9 is installed on the lower side of the guide pipe 5, and a suction pipe 10 is installed on the lower side of the suction pump 9. Two support legs 8 are fixedly connected to the lower outer wall of the furnace body 1. The furnace body 1 is hoisted to the vicinity of the installation position using hoisting equipment, ensuring that the return oil pipe 2, oil outlet pipe 4, and other pipes can be connected smoothly. The power cord of the electric heater 12 is connected to a suitable power supply, ensuring that the wiring is secure and complies with electrical safety regulations. Oil is injected into the furnace body 1 through a special oil injector. Add an appropriate amount of heat transfer oil, open the exhaust valve located at the left end of the furnace body 1, and start the suction pump 9 to circulate the heat transfer oil in the pipeline and expel the air in the system. When the exhaust valve discharges only heat transfer oil and there are no air bubbles, close the exhaust valve, connect the power supply of the electric heater 12, and gradually increase the heating power. When the heating is completed, the suction pump 9 is started again, and the hot oil is extracted through the suction pipe 10 and transported to the equipment to be used through the oil outlet pipe 4. After the equipment has used the hot oil, it flows back to the return oil pipe 2 through the corresponding pipe, waiting to be heated and used again.

[0030] Rollers 18 are provided on both the front and rear sides of the two support legs 8 to guide the furnace body 1 to move. The furnace body 1 is hoisted to the vicinity of the installation position using hoisting equipment. The furnace body 1 is then manually pushed by the rollers 18 to perform fine positioning and adjust its position.

[0031] like Figure 3 As shown, the lower outer walls of the two support legs 8 are fixedly connected to the base plate 14, and the lower outer walls of the two base plates 14 are fixedly connected to the vibration damping pads 15.

[0032] The bottom outer wall of both legs 8 is fixedly connected to the base plate 14, which increases the contact area between the legs 8 and the ground. The vibration damping pad 15 plays a role in buffering and vibration reduction.

[0033] like Figure 3 and Figure 4 As shown, through holes 17 are provided inside the upper outer walls of the two base plates 14 and near the front and rear sides respectively to pre-limit the installation position of the rollers 18. Fixing sleeves 16 are fixedly connected to the inner walls of the front and rear ends of the through holes 17. Fixing plates 19 are provided on the lower inner walls of the two fixing sleeves 16. Screws 23 are fixedly connected to the upper outer walls of the two fixing plates 19. Fixing rods 20 are provided inside the multiple rollers 18 to limit the rotation position of the rollers 18. Fixing heads 21 are fixedly connected to the outer walls of the front and rear ends of the fixing rods 20 to fit on the screws 23 to pre-limit the position of the rollers 18. Nuts 22 are screwed into the other ends of the multiple screws 23 to limit the position of the rollers 18.

[0034] The fixing rod 20 inside the roller 18 restricts the rotation position of the roller 18, allowing it to rotate only around the axis of the fixing rod 20. When the fixing head 21 is fitted onto the screw 23, the nut 22 is tightened. The nut 22 interacts with the fixing head 21, firmly fixing the roller 18 to the base plate 14. At this time, the lower end of the roller 18 contacts the ground, allowing the furnace body 1 to move. When the furnace body 1 moves to the designated position, the nut 22 is loosened, causing the roller 18 to retract into the through hole 17 for storage. When the roller 18 is needed to adjust the position of the furnace body 1 again, the nut 22 is tightened again.

[0035] like Figure 1 and Figure 2 As shown, a control cabinet 7 is provided on the front side of the furnace body 1 to control the heating temperature and duration of the electric heater 12. Multiple heat-conducting rods 11 are fixedly connected at equal intervals on the circular outer wall of the electric heater 12 to guide the heat to diffuse evenly inside the furnace body 1.

[0036] The control cabinet 7 is equipped with various control components and circuits. Through electrical connection with the electric heater 12, it can achieve precise control of the heating temperature and duration of the electric heater 12. The operator can set the required heating temperature and duration parameters on the operation interface of the control cabinet 7. After receiving the setting command, the control cabinet 7 adjusts the input power of the electric heater 12, thereby controlling the heat generated by the electric heater 12, and thus precisely controlling the heating temperature of the heat transfer oil. The heat generated by the electric heater 12 is first transferred to the heat transfer oil in direct contact with it. The heat transfer rod 11 has good thermal conductivity and can quickly absorb the heat generated by the electric heater 12 and transfer it to the heat transfer oil in different locations around it.

[0037] like Figure 1 and Figure 2 As shown, the front end of the oil outlet pipe 4 is provided with a flange 3 to connect with the external conveying pipeline. The left and right ends of the furnace body 1 are provided with sealing ends 6 to seal the furnace body 1. The circular inner wall of the furnace body 1 is provided with a heat insulation layer 13.

[0038] The flange 3 has a series of bolt holes. By passing the bolts through these holes and aligning them with the corresponding holes on the external conveying pipe, and then fixing the bolts, the oil outlet pipe 4 can be tightly connected to the external conveying pipe. The sealing ends 6 set on the outer walls of the left and right ends of the furnace body 1 are mainly used to seal the furnace body 1 to prevent the heat transfer oil from leaking from both ends of the furnace body 1. At the same time, it also helps to maintain the pressure stability inside the furnace body 1. The heat insulation layer 13 set on the circular inner wall of the furnace body 1 has good heat insulation performance. It can reduce the heat loss from the inside of the furnace body 1 to the outside and improve energy utilization efficiency.

[0039] The implementation principle of this embodiment is as follows: The furnace body 1 is hoisted to the vicinity of the installation location using hoisting equipment. This ensures that pipes such as the return oil pipe 2 and the outlet oil pipe 4 can be smoothly connected. The power cord of the electric heater 12 is connected to a suitable power supply, ensuring secure wiring that complies with electrical safety regulations. An appropriate amount of heat transfer oil is injected into the furnace body 1 through a dedicated oil injector. The exhaust valve located at the left end of the furnace body 1 is opened, and the suction pump 9 is started to circulate the heat transfer oil within the pipes, expelling air from the system. When the exhaust valve discharges only heat transfer oil without any air bubbles, the exhaust valve is closed, and the power to the electric heater 12 is turned on, gradually increasing the heating power. After heating is complete, the suction pump 9 is restarted, extracting hot oil through the suction pipe 10 and transporting it to the equipment to be used through the outlet oil pipe 4. After the equipment has used the hot oil, it flows back to the return oil pipe 2 through the corresponding pipe, waiting to be heated again for reuse. The furnace body 1 is hoisted to the vicinity of the installation location using hoisting equipment. The furnace body 1 is manually pushed using the rolling of the rollers 18 for precise positioning and adjustment.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
