Description

Technical Field

[0001] This utility model relates to the technical field of polyester chip production and processing, and in particular to a cleaning and dust removal system for polyester chips. Background Technology

[0002] During the production and transportation of polyester chips, static electricity inevitably accumulates on their surface. This static electricity causes the surface of the polyester chips to attract small amounts of dust from the production environment and polyester particles generated by polyester abrasion. If these dust impurities and particles are not removed, they will not only clog the filters of processing machines, shorten continuous production time, and reduce production efficiency during subsequent processing of polyester products, but also introduce impurities and crystal points into the produced polyester products, affecting their quality. Therefore, dust removal treatment is necessary after polyester chips are formed. Currently, the industry generally uses methods such as mechanical vibration, cyclone separation, or electrostatic adsorption to remove surface dust, but these methods are difficult to completely remove dust, and the dust removal efficiency and automation level are low.

[0031] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0032] like Figure 1 As shown, the cleaning and dust removal system of this utility model includes a spray dust removal device 100 and a vibration dehydration device 200, wherein the spray dust removal device 100 and the vibration dehydration device 200 are arranged sequentially from left to right. In some other embodiments, the spray dust removal device 100 and the vibration dehydration device 200 can be arranged in the front-back direction. In this embodiment, the spray dust removal device 100 and the vibration dehydration device 200 are arranged sequentially from left to right as an example.

[0033] The spray dust removal device 100 includes a spray assembly 110 and a conveying assembly 120. The conveying assembly 120 includes a conveying water tank 121, a conveying screw rod 122 and a rotary drive mechanism 123.

[0037] In operation, the polyester chips to be cleaned and dust-removed are added into the conveying tank 121 through the feed inlet 1211. The conveying grid 124 supports the polyester chips. Under the rotation of the rotary drive mechanism 123, the conveying screw 122 rotates, causing the polyester chips to be spirally conveyed forward along the conveying tank 121. At the same time, multiple spray heads 111 spray and wash the polyester chips during the conveying process. During the spraying and washing, the polyester chips tumble with the conveying screw 122 to thoroughly wash away the dust on the surface of the polyester chips, thereby improving the washing effect. The wastewater after spraying and washing flows down through the conveying grid 124 to the bottom of the conveying tank 121 and is recycled through the return water inlet 1213.

[0038] The vibrating dewatering device 200 of this embodiment includes a water collection tank 210, a dewatering screen 220, and a vibration mechanism 230.
