Problems solved by technology

This granulation method needs to fix a motor position on the granulator, and the flexibility of equipment installation is poor
In addition, polyamide will volatilize a large amount of organic waste gas during granulation. If it is not treated in time, it will cause polluted environment.

Abstract

The invention discloses a granulation mechanism of a polyamide production system. The granulation mechanism comprises a distributing device, a transmission device and an air drafting device arranged above the distributing device. The distributing device comprises a granulation tube and a grain cutting device. The grain cutting device comprises a grain cutter and a transmission shaft, the grain cutter is sleeved with the transmission shaft, a body part of the transmission shaft is contained inside a cavity of the granulation tube, and the two ends of the transmission shaft extend out of the cavity of the granulation tube. Multiple material holes arrayed regularly are formed in the bottom of the granulation tube, a feeding port is formed in the top of the granulation tube, and the material holes, the feeding port and the cavity are communicated with one another. The transmission device comprises a motor, a first gear, a second gear and a chain. The first gear and the second gear are sleeved with the chain, an output shaft of the motor is connected with the first gear, and the second gear is connected with the end of the transmission shaft. The granulation mechanism has the advantages that the installing flexibility of the motor can be improved, and organic waste gas can be purified in due time.

Description

technical field [0001] The invention relates to the field of polyamide preparation, in particular to a granulation mechanism of a polyamide production system. Background technique [0002] Polyamide resin, referred to as PA, is a polymer with amide bonds in the main chain. It can be obtained by polycondensation of dibasic amine and dibasic acid, and ring-opening polymerization of lactam. A variety of polyamide resins can be obtained due to the different types of dibasic acids and diamines used. According to the relative molecular weight, it can be roughly divided into high molecular polyamide resin and low molecular polyamide resin. [0003] High-molecular polyamide resin, known as nylon or nylon, is composed of straight-chain aliphatic dibasic acid and diamine. It is mainly used to prepare synthetic fibers and engineering plastics. It is a kind of polyamide resin with relatively complete development and research technology. . [0004] Low-molecular-weight polyamide resi...
