[0015] 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.

[0016] Example: Please see Figure 1 - Figure 6 The circulating heating device for a rolling mill thin oil station in this embodiment includes a main oil tank 1, a heating rod 2, a first heating oil pipe 3, and a second heating oil pipe 4 symmetrically arranged with the first heating oil pipe 3. The first heating oil pipe 3 and the second heating oil pipe 4 wrap the heating rod 2 from the top and bottom directions. The No. 1 heating oil pipe 3 is coiled in a U-shape on one side of the heating rod 2. The No. 1 heating oil pipe 3 includes multiple wide knots 5 and narrow knots 6. Both the wide knots 5 and narrow knots 6 are U-shaped and are arranged in an alternating pattern. The wide junction 5 of the second heating oil pipe 4 corresponds to the narrow junction 6 of the first heating oil pipe 3, and the narrow junction 6 of the second heating oil pipe 4 corresponds to the wide junction 5 of the first heating oil pipe 3.

[0017] Heating rod 2 is an electric heating rod 2. The heat emitted by heating rod 2 heats heating oil pipe 3 and heating oil pipe 4. The U-shaped coiling allows a single heating oil pipe to wrap around three sides of a single heating rod 2. Two heating rods 2 wrap around the heating rod 2 symmetrically from two directions, and can completely wrap the entire heating rod 2.

[0018] When installing two heating oil pipes, the narrow knot 6 is inserted into the wide knot 5 of the other heating oil pipe. The narrow knot 6 fills the space at the wide knot 5 and wraps around the heating rod 2.

[0019] The heating oil pipe is made of bent metal pipe and has a certain degree of elasticity. If the U-shaped part of the heating oil pipe is bent too narrow when wrapping the heating rod 2, the narrow knot 6 should be located inside the wide knot 5 when the two heating oil pipes are inserted into each other. Then press it to insert the narrow knot 6 into the wide knot 5.

[0020] The main oil tank 1 has mounting plates 7 on both opposite sides. The heating rod 2 is fixedly installed on one of the mounting plates 7. An upper support plate 8 and a lower support plate 9 are fixedly installed between the two opposite mounting plates 7.

[0021] The upper support plate 8 is located on one side of the No. 1 heating oil pipe 3, and the lower support plate 9 is located on one side of the No. 2 heating oil pipe 4.

[0022] The upper support plate 8 and the lower support plate 9 are both fixedly connected to the inner sides of the upper support plate 8 and the lower support plate 9, respectively. The two sets of connecting seats 10 are fixedly connected to the first heating oil pipe 3 and the second heating oil pipe 4.

[0023] The upper support plate 8 and the connecting seat 10 support and fix the first heating oil pipe 3, and the lower support plate 9 and the connecting seat 10 support and fix the second heating oil pipe 4.

[0024] After disconnecting the connecting pipes at both ends of the heating oil pipe, remove the screws at both ends of the support plate and move the support plate away from the heating rod 2 to remove the corresponding heating oil pipe, making it easier for the heating oil pipe to detach from the heating rod 2.

[0025] The main oil tank 1 has a buffer oil tank 11 and a circulation pump 12 on its side. The buffer oil tank 11 is connected to the main oil tank 1, and the circulation pump 12 is connected to the buffer oil tank 11 through a pipeline.

[0026] The first heating oil pipe 3 is connected to the first oil inlet pipe 13 and the first oil return pipe 14 at both ends, and the second heating oil pipe 4 is connected to the second oil inlet pipe 15 and the second oil return pipe 16 at both ends.

[0027] Both the No. 1 oil inlet pipe 13 and the No. 2 oil inlet pipe 15 are connected to the circulating pump 12 via the connecting oil pipe 17.

[0028] Oil enters the buffer tank 11 from the main oil tank 1, driven by the circulation pump 12, and then enters the first heating oil pipe 3 and the second heating oil pipe 4. After passing through the first heating oil pipe 3 and the second heating oil pipe 4, the oil flows back into the main oil tank 1.

[0029] The No. 1 heating oil pipe 3 is detachably connected to the No. 1 oil inlet pipe 13 and the No. 1 oil return pipe 14 at both ends. Similarly, the No. 2 heating oil pipe 4 is detachably connected to the No. 2 oil inlet pipe 15 and the No. 2 oil return pipe 16 at both ends. When it is necessary to repair the heating oil pipe, the heating oil pipe can be removed separately.

[0030] Heating rod 2 includes an insulating shell, a graphite electrode, and a circuit board. The graphite electrode is inserted into the insulating shell, and the circuit board is electrically connected to the graphite electrode. Heating rod 2 heats heating oil pipe 3 and heating oil pipe 4 through electric heating. The equipment also includes existing technology modules such as a temperature detection module, a one-way valve, and a flow meter, which are unrelated to the innovative part of this patent and do not affect the realization of the technical effect of this patent, so they are not shown.

[0031] By changing the coiling structure of the heating oil pipe and adding a connecting seat 10 to support the heating oil pipe, when disassembling the heating oil pipe, it is only necessary to move the heating oil pipe slightly away from the heating oil pipe to remove it. When installing, align the narrow knot 6 of the heating oil pipe with the wide knot 5 of another heating oil pipe to insert the heating oil pipe into the outside of the heating rod 2.

[0032] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not distinguish components based on differences in name, but rather on differences in function.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
