[0002] During the processing of polyurethane adhesive, heating and cooling are required. In order to heat or cool the polyurethane adhesive during the flow process, a coil can be used to transport the polyurethane adhesive, and the coil is placed in the fluid medium in the heat exchanger.

[0016] Combine the following Figure 1 to Figure 2 The technical solution of the utility model is further illustrated by specific embodiments.

[0017] like Figure 1 The coil assembly for polyurethane adhesive shown includes: a first vertical pipe 1, a second vertical pipe 2, a first valve stem 8, a second valve stem 9 and N transverse pipes 3, the N transverse pipes 3 are distributed in parallel up and down. In this embodiment, 6 transverse pipes 3 are used to be distributed in parallel up and down.

[0018] The first vertical pipe 1 is longitudinally arranged at the front end of the N horizontal pipes 3, interconnected, and fixed by welding, with good sealing performance. The front side of the first vertical pipe 1 is provided with a first extension pipe 5 corresponding to the front end of the N horizontal pipes 3, and the ends of the first extension pipes 5 are respectively provided with first blocking bolts 6 to block the first extension pipes 5.

[0019] The second vertical tube 2 is longitudinally arranged at the rear end of the second horizontal tube to the N-1th horizontal tube, connected to each other, and fixed by welding. The rear side of the second vertical tube 2 is respectively provided with a second extension tube 14 corresponding to the second horizontal tube to the N-1th horizontal tube, and the end of the second extension tube 14 is respectively provided with a second plugging bolt 13, and the second extension tube 14 is plugged. After removing the first plugging bolt 6 and the second plugging bolt 13, the cleaning brush can be inserted into the horizontal tube, and the cleaning brush can be rotated and axially moved to clean the inner wall of the horizontal tube, such as Figure 2 As shown, the operation is easy and the blind spots of cleaning are avoided.

[0020] Third blocking bolts 7 are provided at both ends of the first vertical pipe 1 , and fourth blocking bolts 11 are provided at both ends of the second vertical pipe 2 , so as to block both ends of the first vertical pipe 1 and the second vertical pipe 2 to avoid leakage.

[0021] The first valve stem 8 is arranged in the first vertical pipe 1, and the first valve stem 8 is respectively provided with a first valve column 10 located between the Mth transverse tube and the M+1th transverse tube. M is an even number. In the present embodiment, M is smaller than N. The diameter of the first valve stem 8 is smaller than the diameter of the first valve column 10, which does not affect the delivery of the polyurethane adhesive. The diameter of the first valve column 10 corresponds to the inner diameter of the first vertical pipe 1, which prevents the polyurethane adhesive from directly entering the front end of the M+1th transverse tube from the front end of the Mth transverse tube.

[0022] The second valve stem 9 is arranged in the second vertical pipe 2, and the second valve stem 9 is respectively provided with a second valve column 12 located between the M+1th transverse pipe and the M+2th transverse pipe. In this embodiment, the diameter of the second valve stem 9 is smaller than the diameter of the second valve column 12, which does not affect the transportation of the polyurethane adhesive. The diameter of the second valve column 12 corresponds to the inner diameter of the second vertical pipe 2, which prevents the polyurethane adhesive from directly entering the rear end of the M+2th transverse pipe from the rear end of the M+1th transverse pipe, thereby realizing the series connection of N transverse pipes 3.

[0023] like Figure 1 As shown, the end of the first valve stem 8 contacts the third blocking bolt 7 at the corresponding end of the first vertical pipe 1 to limit the axial position of the first valve stem 8, and the structure is stable. The end of the second valve stem 9 contacts the fourth blocking bolt 11 at the corresponding end of the second vertical pipe 2 to limit the axial position of the second valve stem 9. After removing the third blocking bolt 7 and the fourth blocking bolt 11, the first valve stem 8 and the second valve stem 9 can be taken out. Figure 2 As shown, it is convenient to clean the inner walls of the first vertical pipe 1 and the second vertical pipe 2.

[0024] The rear end of the first transverse tube 3 is provided with a liquid inlet pipe joint 4, and the rear end of the Nth transverse tube is provided with a liquid outlet pipe joint 15. The polyurethane adhesive enters the transverse tube 3 from the liquid inlet pipe joint 4, is transported and rotated, and is finally discharged from the liquid outlet pipe joint 15.

For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
