Description

Technical Field

[0001] This utility model relates to the field of polymer material modification and nanocomposite material preparation technology, specifically to a vacuum impregnation and dispersion device for polyester chips containing nano-SiO2 microspheres. Background Technology

[0002] Adding nano-SiO2 microspheres to polyester chips is an important means to improve their mechanical properties, thermal stability, optical properties and functional modification.

[0003] Traditional processes typically employ melt blending, directly adding nanoparticles to molten polyester. However, nanoparticles are prone to agglomeration and uneven dispersion, affecting the modification effect. Another method involves first impregnating the surface and pores of polyester chips with a solution or suspension, followed by melt spinning or molding. However, existing impregnation equipment suffers from the following problems: nanoparticles tend to settle and agglomerate in liquid media, making it difficult to form a stable and uniform dispersion; the impregnation process is mostly conducted at atmospheric pressure, and air in the pores inside the polyester chips hinders the penetration of the impregnation solution, resulting in uneven impregnation, low efficiency, and discontinuous separation and drying processes after impregnation, which can easily lead to secondary agglomeration or contamination.

[0004] Therefore, a specialized device is needed to achieve efficient dispersion of nanoparticles, vacuum-assisted deep impregnation, and integrated processing. Utility Model Content

[0005] To address the problems in related technologies, this utility model proposes a vacuum impregnation and dispersion device for nano-SiO2 microspheres used in polyester chips, thereby overcoming the aforementioned technical problems in existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A vacuum impregnation and dispersion device for nano-SiO2 microspheres for polyester chips includes a hopper, a feeding mechanism is provided outside the hopper, an impregnation mechanism is provided outside the feeding mechanism, a high-speed vacuum tube is provided outside the impregnation mechanism, a vacuum pump is provided outside the high-speed vacuum tube, and a low-speed vacuum tube is provided outside the vacuum pump.

[0007] Preferably, in order to achieve uniform mixing and quantitative conveying of polyester chips and nano-slurry, the feeding mechanism includes a feeding motor, which is located outside the hopper. A feeding pipe is provided outside the feeding motor, a feeding paddle is provided inside the feeding motor, a sauce storage tank is provided outside the feeding pipe, an inlet is provided outside the sauce storage tank, and a metering pump is installed inside the sauce storage tank.

[0008] Preferably, in order to provide a sealed immersion environment and facilitate observation of the process, the immersion mechanism includes an immersion tank, an observation window on the outside of the immersion tank, a sealing ring on the outside of the immersion tank, a sealing cover slidably connected inside the sealing ring, and a support rod on the outside of the sealing cover.

[0009] Preferably, in order to facilitate material loading and unloading, instrument monitoring, and material discharge after impregnation, the sealing cover is provided with a feed inlet, an air outlet, and an instrument interface on the outside; the impregnation tank is provided with a discharge outlet, a discharge valve is provided on the outside of the discharge outlet, and a distribution component is provided inside the sealing cover.

[0010] Preferably, in order to achieve multi-level uniform distribution and atomized spraying of the nano-slurry, the distribution component includes an outer distribution channel, the outer distribution channel is located outside the sealing cover, a high flow distribution port is opened inside the outer distribution channel, a lower-level channel is provided outside the outer distribution channel, a subdivided channel is provided outside the lower-level channel, and an atomizing nozzle is installed inside the subdivided channel.

[0011] Preferably, in order to adjust the spatial position of the polyester chips during the impregnation process to promote slurry penetration, a drive motor is slidably connected inside the sealing cap, a lifting stud is inside the drive motor, a connecting base is threadedly connected to the outside of the lifting stud, and a lifting tray is provided on the outside of the connecting base.

[0012] Preferably, in order to utilize ultrasound to assist in the dispersion of nanoparticles in the slurry and prevent their agglomeration during impregnation, the impregnation tank is equipped with an ultrasonic transducer.

[0013] The beneficial effects of this utility model are as follows: 1. The precise and controllable feeding of polyester chips and nano-slurry is achieved through the storage bin and feeding mechanism, which significantly reduces the resistance of nano-slurry wetting, allowing it to fully coat and penetrate the chips, thereby achieving a highly uniform load of nanoparticles on the surface and near the surface of the chips and improving impregnation efficiency.

[0014] 2. By combining vacuum impregnation with ultrasonic dispersion, air in the pores of polyester chips is effectively removed, promoting deep penetration of the nano-dispersion liquid and improving impregnation uniformity and efficiency. The multi-level distribution channel and atomizing nozzle structure achieve uniform spraying of the nano-dispersion liquid, avoiding local accumulation and agglomeration. The integrated lifting tray and ultrasonic transducer enable dynamic adjustment and auxiliary dispersion of materials during impregnation, improving process controllability and consistency.

The sauce storage tank 24 stores pre-dispersed nano-SiO2 slurry, and the slurry delivery rate is precisely controlled by the metering pump 26. The feeding motor 21 drives the feeding paddle 23 to mix the polyester chips with the slurry and then feed it into the impregnation tank 31.

[0021] like Figure 1-5 As shown, the device of this utility model mainly includes a silo 1, a feeding mechanism 2, an impregnation mechanism 3, a high-speed vacuum tube 4, a low-speed vacuum tube 5, and a vacuum pump 6. The silo 1 is used to store polyester chips. The feeding mechanism 2 feeds the chips and nano-slurry into the impregnation mechanism 3 in a certain proportion. The impregnation mechanism 3 includes an impregnation tank 31, which is equipped with a lifting tray 310. The lifting of the tray is achieved by a drive motor 315, a lifting stud 313, and a bottom connecting base 312. The sealing cover 34 is opened and closed by a support rod 314. The sealing cover 34 and the outer sealing ring 33 are tightly engaged to ensure the internal vacuum level, which facilitates the entry and exit of materials and the position adjustment during the impregnation process. The upper inlet 35 and the air outlet 36 ensure the entry of external media. The sealing cover 34 is equipped with a distribution component, including an outer distribution channel 316, a high flow distribution port 317, a lower-stage channel 318, and a subdivided channel 319. The end is equipped with an atomizing nozzle 320, which can achieve uniform spraying of nano-slurry. An ultrasonic transducer 311 is installed inside the impregnation tank 31 to assist dispersion. The vacuum system is connected to the vacuum pump 6 through the high-speed vacuum tube 4 and the low-speed vacuum tube 5 to establish and maintain the vacuum environment inside the impregnation tank.

[0022] Working Principle: In use, polyester chips are first placed in the hopper 1, and nano-SiO2 slurry is loaded into the sauce storage tank 24. The feeding mechanism 2 is activated, and the polyester chips and slurry are mixed in a set ratio and then fed onto the lifting tray 310 in the impregnation tank 31. The sealing cover 34 is closed, and the vacuum pump 6 is activated, drawing air from the tank through the high-speed vacuum tube 4 and the low-speed vacuum tube 5 to create a vacuum environment. The distribution component is activated, and the nano-slurry is evenly sprayed onto the chip surface through the atomizing nozzle 320 via the outer distribution channel 316, the lower-stage channel 318, and the subdivided channel 319. Simultaneously, the ultrasonic transducer 311 is activated to assist in slurry penetration and dispersion. After impregnation, the discharge valve 37 is opened, and the material is discharged through the discharge port 38. Throughout the process, the immersion status can be monitored through the observation window 32, and the instrument interface 39 connects to the sensor to realize real-time monitoring of process parameters. After immersion is completed, the lifting tray 310 can be lifted to remove the material. The outer edge of the lifting tray 310 pushes up the support rod 314 to lift up the sealing cover 34 and remove the material from the lifting tray 310.
