Problems solved by technology

[0003] However, the hopper of the traditional slicing boiling crystallization dryer for polyester chemical fiber production provides preheating for the raw materials. During the preheating process, the heating device is placed directly on the bottom of the hopper for heating. There is no sealing mechanism on the top, which causes the water in the raw material to evaporate uncleanly, resulting in incomplete crystallization, which is prone to blockage during feeding, and the feeding speed is slow

Embodiment Construction

[0027] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0028] Such as figure 1 with Figure 5 Shown, a kind of chemical fiber spinning drying process of the present invention, this process comprises the following steps:

[0029] S1, sending the slices into the dust collector for dust removal;

[0030] S2, sending the dedusted slices in S1 into a crystallization dryer for crystallization and drying;

[0031] S3, sending the slices discharged in S2 to the next process;

[0032]The crystal dryer used in this process includes a feeding mechanism 1, a heating mechanism 2, an air extraction head 3, a discharging mechanism 4, a fixing mechanism 5, a storage mechanism 6, a sealing mechanism 7 and an encryption mechanism 8; The top of the feeding mechanism 1 is provided with the sealing mechanism 7 for sea...

Abstract

The invention relates to the technical field of chemical fiber production, in particular to a chemical fiber spinning drying process. A crystallization and drying machine used in the process comprisesa feeding mechanism, a heating mechanism, a pumping head, a discharging mechanism, a fixing mechanism, a loading mechanism, a sealing mechanism and an encryption mechanism. The inner side wall of aninner casing is fixedly connected in an equidistant and symmetric manner to heat conducting plates with the side of an arc-shaped structure and arranged in an inverted splayed structure. Heating pipesare arranged in a Z-shaped structure inside the plurality of heat conducting plates. For one thing, the contact area is enlarged, so that the water in the raw material evaporates more completely andcrystallizes completely, and for another, blocking of the raw material between the two heat conducting plates during the blanking is avoided, so that the blanking is smoother. The bottom of the innercasing is fixedly connected to a blanking pipe. A blanking groove is formed spirally inside the blanking pipe. The blanking groove at the bottom of the inner casing has an inverted splayed structure.The blanking groove at the bottom of the blanking pipe has a splayed structure. The blanking is facilitated and is made smoother.

Description

technical field [0001] The invention relates to the technical field of chemical fiber production, in particular to a chemical fiber spinning and drying process. Background technique [0002] Crystallization dryer is also known as stirring dryer, pre-crystallization machine, pre-crystallization dryer, polyester is an important variety in synthetic fibers, and it is the trade name of polyester fiber in my country. It is a fiber-forming high polymer prepared from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation reactions—— Polyethylene terephthalate (PET) is a fiber made by spinning and post-processing. In chemistry, after the hot saturated solution is cooled, the solute is precipitated in the form of crystals. This process is called crystallization. [0003] However, the hopper of the traditional slicing boiling crystallization dryer for polyester chemical fiber produc...
