Embodiment 1

[0016] Such as figure 1 , 2 As shown, the novel drying device for polyester yarn described in this embodiment includes a drying box 1 and a drawer 2 matched with the drying box 1, and a temperature sensor 3 and a magnetron are arranged in the drying box 1. 4. An electromagnetic lock 5 is provided on the side of the panel 8 of the drawer 2, and a humidity sensor 6 is provided on the drawer 2. The temperature sensor 3 and the humidity sensor 6 are connected to a collector, and the collector is connected to a PID through a processor. Controller, PID controller connects described magnetron 4 through digital-to-analog converter, magnetron 4 pulse controllers; Described drawer 2 is provided with upper, middle and lower three-layer pallet 7, and described humidity sensor 6 is installed on On the panel 8 of the drawer 2 and the measuring end of the humidity sensor 6 is located between the pallets 7 . Wherein, the circuit system adopted in this embodiment is disclosed in Chinese pate...

Embodiment 2

[0020] Such as image 3 , 4 As shown, the new drying device for polyester yarn described in this embodiment is different from Embodiment 1 in that: the humidity sensor 6 is divided into a first humidity sensor 61 and a second humidity sensor 62, and the first humidity The sensor 61 is located between the upper and middle two pallets 7, the second humidity sensor 62 is located between the middle and lower two pallets 7, and the first humidity sensor 61 and the second humidity sensor 62 are connected to each other through an average value circuit. the collector.

[0021] The humidity between the upper and middle two pallets is slightly different from the humidity between the middle and lower two pallets (the upper part is slightly higher than the lower part), and the humidity can be controlled more evenly after taking the average value. The average value circuit is an existing technology, as described in Chinese patent ZL2013203272441, it can be a current average value circuit...

Abstract

The invention discloses a novel drying device of polyester filaments. The device comprises a drying box and a drawer matched with the drying box. A temperature sensor and a magnetron are arranged in the drying box. An electromagnetic lock is arranged on the lateral side of a panel of the drawer. Humidity sensors are arranged on the drawer. The temperature sensor and the humidity sensors are connected with a collector. The collector is connected with a PID controller through a processor. The PID controller is connected with the magnetron through a digital-analog converter and a magnetron pulse controller. An upper supporting plate, a middle supporting plate and a lower supporting plate are arranged in the drawer. The humidity sensors are installed on the panel of the drawer, and the measuring ends of the humidity sensors are located between the supporting plates. The invention further discloses a drying method of the polyester filaments. The novel drying device and drying method of the polyester filaments have the advantages that the humidity index is adopted to serve as a control signal, and the magnetron can be stopped when the internal humidity is small to prevent the polyester filaments from being over-dried.

Description

technical field [0001] The invention relates to a production equipment and a production process of polyester yarn, in particular to a novel drying device and a drying method of polyester yarn. Background technique [0002] Polyester yarn drying is an important process after mechanical dehydration of polyester yarn. The dyeing and finishing industry in my country is developing rapidly, and it is required to improve production efficiency, reduce labor costs, and save energy. The existing domestic drying equipment mainly uses hot air drying, not only Low productivity, high maintenance costs, and high energy consumption, and because temperature is used as the measurement signal, it is easy to cause over-drying, which can easily cause quality problems such as yellowing, embrittlement, and uneven moisture content of white polyester yarn . [0003] As an improvement of the above-mentioned existing hot air drying, a magnetron is used for heat supply, and a magnetron is an electric va...
