Description

Technical Field

[0001] This utility model relates to the technical field of glass fiber production equipment, specifically a closed-type integrated glass fiber pretreatment device. Background Technology

[0002] Before glass fiber is used as a reinforcing material, it usually needs to undergo pretreatment processes such as cutting, surface impregnation (e.g., coating with coupling agent), and pre-drying. Traditionally, these processes are mostly completed using dispersion equipment. Existing equipment generates a large amount of glass fiber dust during the cutting process, and the impregnation and drying processes easily release volatile organic solvents or treatment agent waste gas, which directly leaks and endangers workers' health and the environment; each process is carried out by independent equipment, and materials need to be transferred multiple times, which is inefficient and can easily cause secondary pollution and fiber damage. To address the problems existing in the above-mentioned technologies, a closed-loop integrated glass fiber pretreatment device is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 A closed-loop integrated glass fiber pretreatment device, characterized in that it comprises: Enclosed shell 1: Made of corrosion-resistant material, forming a sealed cavity, with a raw material inlet 101 and a finished product outlet 102 with sealing structure at both ends; Integrated pretreatment unit: Integrated inside a closed housing 1, comprising, in sequence along the material travel direction: a cutting mechanism 2 for cutting glass fiber raw materials entering the housing to a fixed length; an impregnation mechanism 3 located downstream of the cutting mechanism 2, including a liquid storage tank 302 and a spraying device 301 for impregnating the cut glass fiber with a treatment agent; and a pre-drying mechanism 4 located downstream of the impregnation mechanism 3, including a hot air circulation device 401 and a guide plate 402 for preliminary drying of the impregnated glass fiber. Material conveying mechanism 5: passing through cutting mechanism 2, impregnation mechanism 3 and pre-drying mechanism 4, used to continuously convey glass fibers through each pretreatment process in sequence; Negative pressure dust removal and exhaust gas treatment mechanism: connected to the interior of the enclosed housing 1, including: A negative pressure suction port 6 is located inside the enclosed housing 1; A dust collector 7 connected to the negative pressure suction port 6; Exhaust gas collection pipe 8 is connected to the interior of the enclosed shell 1; The waste gas treatment device 9 is connected to the waste gas collection pipe 8, and the waste gas treatment device 9 is equipped with an activated carbon adsorption layer.

[0015] Specifically, the cutting mechanism 2 is a rotary cutter assembly or a laser cutter.

[0016] Specifically, the spraying device 301 of the immersion mechanism 3 consists of multiple rows of adjustable angle nozzles that evenly cover the glass fiber on the conveyor belt.

[0019] Specifically, the enclosed housing 1 is provided with an inspection door 10, and the edge of the inspection door 10 is provided with a sealing strip.

[0020] Working principle: Glass fiber filaments enter the closed housing 1 through the raw material inlet 101 to prevent external air from seeping in. The fibers are fed into the cutting mechanism 2 by the material conveying mechanism 5. The rotary cutter or laser cutter precisely cuts the fibers to the set length. The glass fiber dust generated at the moment of cutting is immediately sucked in by the negative pressure dust suction port 6 above and sent to the dust collector 7 through the pipeline for filtration and collection, preventing dust from escaping. The cut fibers continue to be conveyed to the impregnation mechanism 3. Spray mode: The treatment agent is pumped out from the liquid storage tank 302 and sprayed evenly onto the fiber surface through multi-angle nozzles. Excess liquid flows back to the liquid storage tank for recycling. The volatile organic solvent is collected by the exhaust gas collection pipe 8 at the top of the housing. The impregnated wet fibers enter the pre-drying mechanism 4. The hot air circulation device 401 generates a high temperature airflow of 80-120°C, which penetrates the fiber layer under the guidance of the guide plate 402, evaporating excess solvent / moisture. The pre-dried fibers are output through the finished product outlet 102 and enter the next deep processing process.
