PTA powder chain plate conveying system

Abstract

The invention discloses a PTA powder chain plate conveying system which comprises a feeding system, a dedusting system and a conveying system body. The feeding system comprises a feeding tank, the dedusting system comprises a deduster and a dedusting fan, and the conveying system body comprises a first horizontal pipe chain conveyor, a second vertical pipe chain conveyor and a third horizontal pipe chain conveyor which are sequentially connected. A manual feeding hopper is arranged at the top of the feeding tank, a tank wagon unloading opening is formed in the side wall of the feeding tank, and the bottom of the feeding tank is connected with the feeding end of the first horizontal pipe chain conveyor. The deduster is arranged on one side of the manual feeding hopper, the bottom of the deduster is connected with the feeding tank, and the top of the deduster is connected with the dedusting fan through a pipeline, wherein the dedusting fan is arranged outdoors. The lower portion of the discharging end of the third horizontal pipe chain conveyor is connected with a PTA powder bin. The PTA powder chain plate conveying system provided by the invention is simple in technology, low in cost, safe, efficient and easy to control, achieves continuous and remote conveying of PTA powder, and ensures stable operating of production.

Description

【Technical field】 [0001] The invention belongs to the technical field of chemical raw material conveying equipment, and more specifically relates to a PTA powder chain plate conveying system. 【Background technique】 [0002] Purified terephthalic acid (PTA) is the main raw material for the production of polyester fiber, resin, film and container resin, and has been widely used in chemical fiber, container, packaging, film production and other fields. However, with the rapid development of my country's petrochemical industry and the continuous expansion of the scale of the polyester industry, the demand for PTA powder is increasing, so people's requirements for polyester equipment are also getting higher and higher. PTA powder transportation is an important link in the polyester production process, how to realize its safe, efficient and stable transportation has gradually become the focus of the chemical industry. [0003] At present, in the chemical polyester industry, most ...

AI Technical Summary

Problems solved by technology

[0003] At present, in the chemical polyester industry, most of the existing PTA powder transportation uses Roots blower to compress the nitrogen and then uses the rotary valve to use nitrogen as the power for pneumatic transportation. However, with the extension of the transportation distance, the nitrogen transportation pressure will gradually decrease. This will easily lead to unstable delivery of PTA powder, which not only greatly reduces the delivery efficiency and affects the production progress, but also increases the use of nitrogen and energy consumption during the delivery process, which is not conducive to energy conservation and environmental protection
