[0017] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 , 2 3 is a specific embodiment of the hot melt adhesive tank oil heating pipeline structure of the utility model. This embodiment includes a heat exchanger body 1 and a heat transfer unit 2 arranged on the side wall of the heat exchanger body 1, characterized in that: the heat transfer unit 2 includes an oil inlet pipe 21, an oil outlet pipe 22 and a plurality of heat transfer pipes 23, the oil outlet pipe 22 is horizontally arranged at the top, the oil inlet pipe 21 is horizontally arranged at the bottom, the plurality of heat transfer pipes 23 are arranged between the oil inlet pipe 21 and the oil outlet pipe 22 at intervals and are connected to the oil inlet pipe 21 and the oil outlet pipe 22, the oil inlet pipe 21 is used for the inflow of hot oil, the hot oil flows through the plurality of heat transfer pipes 23 respectively, and flows out from the oil outlet pipe 22.

[0019] When the utility model is in use, the heat transfer unit 2 is arranged on the four side walls of the heat exchanger body 1 according to the size of the specification, or is arranged at different heights of the four side walls. When the heat transfer unit 2 is in use, the hot oil enters the oil inlet pipe 21 after being pressurized, and the hot oil is distributed to each heat transfer pipe 23. More heat transfer pipes 23 disperse the hot oil flow, slow down the hot oil circulation speed, and force it to conduct heat more fully. Relying on the heat transfer surface formed by the spaced arrangement of a number of heat transfer pipes 23, the heat is fully introduced into the heat exchanger body 1, and the colloid to be heated and melted in the heat exchanger body 1. Afterwards, the oil is concentrated and flows out from the oil outlet pipe 22 above the heat transfer pipe 23 for collection, and re-enters the heating cycle after heating. Compared with the existing long pipeline heating method, the long pipeline oil channel is too long, and the heat energy cannot be quickly updated during the circulation process; there are too many pipeline welding, high welding requirements, and cumbersome processes; when encountering a large number of rubber blocks to be melted, the heat supply cannot keep up, resulting in slow melting of the rubber; during the long circulation process, the oil temperature in the pipeline drops and it is impossible to stably supply heat. The utility model shortens the circulation stroke of the hot oil, thereby reducing the head requirements of the hot oil pump and reducing the circulation resistance; more heat pipes 23 increase the heat conduction contact area and increase the refresh frequency of the hot oil supply; the downward flow combined with multiple heat pipes 23 increases the relative residence time of the hot oil in the heat conduction pipeline, making the heating process more uniform, and the short pipeline reduces the temperature difference between the head and the tail.

[0020] As an improved specific implementation manner, a plurality of heat conducting pipes 23 are evenly arranged between the oil inlet pipe 21 and the oil outlet pipe 22 .

[0021] like Figure 1 As shown, a plurality of heat conducting pipes 23 are evenly arranged so that the entire heat conducting unit 2 has uniform heat conducting performance after being arranged on the side wall of the heat exchanger body 1, so that the heat conduction of the entire contact surface is uniform and the colloid is melted uniformly.

[0022] As an improved specific implementation manner, the surface of the heat-conducting pipe 23 is provided with heat exchange fins 3 extending outward for heat conduction.

[0023] like Figure 1 As shown, the heat exchange fins 3 form a contact surface extending outward along the length direction of the heat conducting tube 23, and the heat exchange fins 3 greatly increase the surface area in contact with the outside, so that the heat contacts the outside more fully and promotes the outward conduction of heat.

[0024] As an improved specific implementation, the oil inlet hole 211 of the oil inlet pipe 21 and the oil outlet hole 221 of the oil outlet pipe 22 are respectively located on both sides thereof in the horizontal direction.

[0025] like Figure 1 , 2As shown, the oil inlet hole 211 and the oil outlet hole 221 are arranged on both sides, so that the hot oil can flow more fully diagonally and fill all the heat pipes 23, so that the heating process of the entire heat conduction unit 2 is more uniform.

[0026] As an improved specific implementation, the side wall of the heat exchanger body 1 includes an upper wall 11, a middle wall 12 and a lower wall 13 connected in sequence, the middle wall 12 is funnel-shaped and reduced in size, and the heat conduction unit 2 is arranged at the middle wall 12 and the lower wall 13.

[0027] like Figure 2 , 3 As shown, the upper wall 11 has a larger diameter to facilitate the placement of the colloid, and the funnel-shaped middle wall 12 allows the colloid to lean against the heat-conducting unit 2 in contact with the side wall to promote melting due to heat. After melting due to heat, the colloid falls more smoothly to the bottom position surrounded by the lower wall 13, and the heat-conducting unit 2 at the lower wall 13 continues to heat to achieve sufficient and uniform melting of the colloid.

[0028] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
