Description

Technical Field

[0001] The utility model relates to the technical field of nylon materials, and more specifically to a mixing and stirring kettle for producing nylon materials. Background Art

[0002] Polyamide, commonly known as nylon, is a general term for thermoplastic resins containing repeated amide groups on the main chain of the molecule. It is widely used. In the production process, nylon is produced according to the formula components through cross-linking reaction, premixing of additives, stirring and other processes to obtain nylon raw materials for extrusion molding. Therefore, the stirring and mixing of nylon raw materials is the key to the production efficiency and quality of nylon.

[0003] The stirring kettle in the prior art generally adopts a rotating agitator structure in the kettle body. The agitator generally adopts a variety of single forms such as anchor type, frame type, and spiral screw. For the mixed material system whose viscosity increases with the extension of the stirring process, wall adhesion and bottom deposition are easy to occur. The laminar flow generated by scraping the wall of the kettle body with only the spiral ribbon structure is slow, resulting in poor stirring and mixing efficiency of the mixed material system, prolonged nylon material production cycle, and difficulty in meeting production needs.

[0004] In the Chinese utility model patent application number: CN202021470182.6, a mixing and stirring kettle for nylon material production is disclosed, including a kettle body, a rotating shaft driven by a rotating motor is arranged in the kettle body, a spiral belt attached to the inner wall of the kettle body is arranged outside the rotating shaft, and a plurality of first screws and second screws are arranged between the inner wall of the spiral belt and the rotating shaft. The mixing and stirring kettle for nylon material production improves the mixing efficiency and the uniformity of the mixing quality of nylon materials, and meets the production requirements of nylon. However, when the device stirs the nylon material, it only stirs the nylon material in a single direction, and the stirring effect is poor. In addition, the speed of discharging the nylon material is slow, and the nylon material is easy to adhere to the inner wall of the discharge port and block the discharge port.

[0005] Therefore, it is necessary to propose a mixing and stirring kettle for nylon material production to solve the above problems. Utility Model Content
