A discharge mechanism of a granulator for pct production

Abstract

The invention discloses a discharging mechanism of a pelletizer for PCT production, and relates to the field of PCT production devices. The discharging mechanism comprises a guide plate, a screen box,an air-cooled box, two side plates and a dust suction box, wherein the guide plate is fixedly connected in the middle of the two side plates; the lower end of the guide plate is fixedly connected tothe upper end of one side of the screen box; the two side edges of the upper end of the screen box are fixedly connected in the middle of the side plates; the upper end of the screen box in the middleof the side plates is fixedly connected with a shaft sleeve; and the middle of the shaft sleeve is fixedly connected with a rotating column. By means of the discharging mechanism of the pelletizer for PCT production, through a cooling device, particles after discharging can be cooled so as to avoid the softening and adhesion of the particles; the dust generated during discharging can be absorbedby a dedusting device, so that the dust is prevented from mixing into the particles to affect the quality, and the dust pollution is reduced and the human health is protected; and through a screeningdevice, the manufactured particles can be screened according to the size, and are discharged and collected separately, so that the particles are sorted and collected according to a certain specification and is convenient to store.

Description

technical field [0001] The invention relates to the field of PCT production devices, in particular to a discharge mechanism of a granulator for PCT production. Background technique [0002] PCT resin is a high-temperature-resistant, semi-crystalline thermoplastic high-temperature-resistant, semi-crystalline thermoplastic. It is another new product in the polyester family. It was industrialized by Eastman Chemical Company (Eastman) in 1987 and has been monopolized until now. Production of PCTs. PCT resin is polymerized from 1,4-cyclohexanedimethanol (abbreviated as CHDM) and dimethyl terephthalate (abbreviated as DMT). The main production raw materials of PCT resin are CHDM, DMT or terephthalic acid (PTA for short), etc., and DMT is the reaction product of PTA and methanol. [0003] In the production process of PCT resin, a granulator will be used to divide the produced PCT resin into granular raw materials commonly used in the market. When the PCT resin granulator is disch...

Problems solved by technology

[0003] In the production process of PCT resin, a granulator will be used to divide the produced PCT resin into granular raw materials commonly used in the market. When the PCT resin granulator is discharged after granulation, due to the particle size Uneven, and can not be screened well, which will affect the quality of raw materials, and will produce dust when cutting, dust will affect human health, the traditional PCT resin granulator is not used when discharging, and one can be very good The mechanism of dust removal has a certain impact on the work, and the traditional granulator does not have a good cooling mechanism when discharging, and cannot cool the resin particles well.
