[0002] The chips produced by the nylon PA6 post-polymerizer still contain about 10% caprolactam monomers and oligomers. The presence of these caprolactam monomers and oligomers cannot be used to produce high-quality filament-grade high-speed spinning nylon PA6 chips. Therefore, the chip raw materials need to be further processed. At present, the common extraction towers in China mostly adopt long cylindrical structures, and there are many dead corners in the internal structure, which seriously affects the extraction quality and efficiency of nylon PA6 chips.

[0019] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0020] like Figure 1 As shown, the nylon polymerization device extraction tower in one embodiment of the utility model comprises an elongated tower body 1 having a cavity, windows 12 can be arranged at different positions on the tower body 1, and such windows can be observation windows or operation windows. A long axis and a tooling mold arranged in the cavity are also arranged in the tower body 1, the long axis comprises an axis body 2 arranged along the extension direction of the elongated tower body and a distribution cone 21 arranged on the axis body at intervals, the tooling mold is arranged in a one-to-one correspondence with the distribution cone, and the tooling mold comprises a guide plate, which is carried on the cone body (such as Figure 1 As shown, when observed perpendicularly to the paper, the guide plate is supported on the conical body of the distribution cone 21, and the guide plate limits the space at its location. Specifically, the guide plate may include a conical portion 13 that fits with the surface of the conical body, and the conical portion 13 is formed with a cavity for accommodating the conical body on the side adjacent to the conical body. In addition, the outer edge of the conical portion may also be formed with a trumpet portion 14 extending from the conical body toward the tower body. The trumpet portion 14 is folded compared to the conical portion, and the folding direction is away from the side of the conical body supporting the conical portion. Furthermore, the folding angle formed by the trumpet portion 14 and the conical portion 13 is 60-120 degrees. This angle design can fully support the material and separate the extract during the extraction process, and is beneficial to fully realize the separation of extracts in different phases after the extraction is completed. As shown Figure 2 As shown, a plurality of conical bodies with the same specifications can be arranged in the same direction on the shaft body.

[0021] In addition, since the long axis is liftable and detachable relative to the tower body 1 in this solution, in order to ensure greater safety in application, a clamping portion 22 for assembly is further provided at the lower end of the shaft body 2. Correspondingly, a bearing frame 15 is further provided at the lower end of the chamber of the tower body near the lower cone 11. The bearing frame 15 can be fixed as a bearing structure of the long axis, such as being welded to the inner wall of the tower body 1. The bearing frame 15 can also be formed into a cone-shaped structure, and a clamping position 16 matching the clamping portion 22 is provided at the lower end of the cone-shaped structure. The cooperation between the clamping portion 22 and the clamping position 16 can be similar to the cooperation between the reference shaft and the shaft pivot, and the clamping position 16 plays a role of bearing and limiting.

[0022] During the extraction operation, after the long axis is assembled into the tower body 1, it is perpendicular to Figure 1 From the perspective shown, after the bottom tooling mold is assembled on the bottom distribution cone 21, the nylon slices can be filled to an appropriate thickness, and then the second tooling mold above can be installed and material can be added again until the material addition is completed, and then the extraction liquid is poured into the cavity of the tower body. After the closure, the extraction begins, and the extraction state can be observed through the observation window. After the extraction is completed, the material in the tower body is emptied, and the cleaning operation can be performed through the operation window. After the cleaning is completed, the next round of operation can be carried out.

[0023] Furthermore, pressure gauges, sensors, etc. can be arranged at different positions of the tower body to facilitate monitoring of the implementation status of the extraction in the tower.

[0024] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
