Description

Technical Field

[0001] This utility model relates to the technical field of water electret devices for meltblown fabric, specifically, to a low-resistance, high-efficiency water electret device for meltblown fabric. Background Technology

[0002] Among nonwoven materials, meltblown nonwoven fabric is widely used in filtration, medical and health, and environmental protection fields due to its fine fiber diameter and large specific surface area. To improve the filtration performance of meltblown nonwoven fabric, it is usually necessary to perform electret treatment. By introducing and retaining permanent charges in the fibers, the Coulomb force of the charges is used to adsorb particulate matter, thereby significantly improving filtration efficiency without significantly increasing the material resistance.

[0003] Electret treatment technology is a crucial step in the production of meltblown nonwoven fabrics. Currently, the mainstream electret methods include corona electret and water electret. Among these, water electret technology has gradually become a research and application hotspot due to its ability to impart more stable charge characteristics and superior overall performance to the material. The water electret device applies a high-pressure water jet to the meltblown fiber web, causing the fibers to polarize and introduce charges. Simultaneously, the scouring effect of the water flow optimizes the fiber's microstructure, further enhancing the material's filtration performance and charge stability.

[0004] However, during the process of water flowing through the meltblown fabric, the water flow resistance is relatively large, and a high water supply pressure is required to form an effective jet. This not only increases energy consumption, but may also cause damage to the fiber structure due to the violent impact of the high-pressure water flow, which in turn increases the air permeability resistance of the material and affects the electret effect of the meltblown fabric. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a low-resistance, high-efficiency meltblown water electret device to solve the technical problem of high resistance in the process of water flowing through meltblown cloth in the prior art.

The winding frame is arranged on both sides of the fixed frame, and a winding roller is rotatably arranged inside each winding frame.

The electret mechanism is arranged on the fixed frame for electreting meltblown fabric, and the collection mechanism is arranged on the fixed frame for collecting water mist generated during the electret process.

[0007] Preferably, the electret mechanism includes a water supply pipe, a fourth support plate, a water tank, and a water pump. Two water supply pipes are provided on the top side of the fixed frame. A third support plate is fixedly provided at both ends of each water supply pipe. The third support plate is fixedly connected to the fixed frame.

[0008] Furthermore, the collection mechanism includes a collection chamber, a collection box, a collection pipe, a centrifugal fan, and a water mist treatment mechanism.

[0026] Reference Figures 4-6 The water mist treatment mechanism includes a first housing 19, a sponge 20, a filter mechanism, and a squeezing mechanism. The first housing 19 is mounted on the bottom side wall of the box cover. The input end of the centrifugal fan 18 extends into the first housing 19. An air inlet is provided at the bottom end of the first housing 19. The sponge 20 is filled and disposed inside the first housing 19.

The electric push rod 24 is installed on the cover of the box. The output end of the electric push rod 24 is fixedly connected to the sieve plate 23. Specifically, after the water mist enters the collection box 16 through the collection pipe 17, the water mist can be initially collected by the water collected in the collection box 16.

After the droplets gather inside the sponge 20, they will form a water flow due to gravity or capillary action and be collected in the collection box 16. After collection, the sponge 20 can be squeezed by the operation of the electric push rod 24. Then, the filter plate 22 can be backwashed by the squeezed water flow.

[0027] In this embodiment, during use in a clean factory environment, the operator winds the meltblown fabric wound on one of the take-up rollers 7 around the guide roller 5 and the support roller 2, then passes it through the drying box 25 and winds it onto another take-up roller 7. The first motor 8 then pulls the meltblown fabric to move it. During this movement, water is supplied to the water supply pipe 9 by the water pump 14. The water is then sprayed in a fan shape through the water supply hose and nozzle 12, facilitating electret treatment of the meltblown fabric. During electret treatment, a negative pressure is generated in the collection box 16 by the centrifugal fan 18, allowing water mist to be collected through the collection pipe 17 and collection chamber 15. Furthermore, while high-pressure water jets are spraying the meltblown fabric, the water mist is also collected through the collection chamber 16. The negative pressure suction of 5 allows water to penetrate the meltblown cloth more smoothly, enhances the friction effect, and makes the charge distribution more uniform, thereby reducing the resistance of the meltblown cloth and improving the electret efficiency. After the water mist enters the collection box 16 through the collection pipe 17, the water mist can be initially collected by the water collected in the collection box 16. Then, the airflow and impurities in the water mist can be filtered by the filter plate 22. Then, the porous structure of the sponge 20 can capture the water mist through interception and adsorption. After the droplets gather inside the sponge 20, they will form a water flow due to gravity or capillary action and be collected in the collection box 16. After collection, the sponge 20 can be squeezed by the operation of the electric push rod 24, which facilitates the backwashing of the filter plate 22 by the squeezed water flow.
