Description

Technical Field

[0001] The utility model relates to the technical field of melt-blown nonwoven fabric production, in particular to a sealed dust-cleaning melt-blown nonwoven fabric electrostatic electret device. Background Art

[0002] Meltblown nonwoven fabrics are widely used as filter materials, medical and sanitary materials, environmental protection materials, and clothing materials. When meltblown fabrics are used for filter materials and medical and sanitary materials, their filtration performance requirements are very high. The filtration performance of meltblown nonwoven fabrics themselves is only less than 70%. To improve its filtration performance, the current common method is to add electrostatic charge effect to meltblown fabrics through the electrostatic electret process, and use electrostatic methods to improve the filtration efficiency, which can reach 99.9%;

[0003] Electrostatic electret, abbreviated as electret, "electrode" refers to charge, and "electret" refers to application. The electrostatic electret equipment attaches the charge to the meltblown non-woven fabric through high-voltage discharge. The electrostatic electret technology makes the filter material fibers charged. Combined with the dense characteristics of the meltblown ultrafine fiber material, a large number of electrodes are formed between the charged fibers. The charged fibers can not only attract most of the charged particles in the environment like a magnet, but also polarize some of the charged particles, thereby adsorbing some smaller pollutants. Even nano-scale substances such as viruses can be electrostatically adsorbed or blocked by charge repulsion. It can be seen that the filter material treated with electrostatic electret has the advantages of high efficiency, low resistance, and adsorption of extremely small particles.

[0004] When the existing device performs electrostatic charging treatment on non-woven fabrics, the dust generated in the process cannot be processed, and the electrostatic charging effect is often poor due to the insufficient expansion coefficient of the non-woven fabrics, which affects the production quality of the non-woven fabrics.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a sealed cleaning melt-blown non-woven fabric electrostatic charging equipment is proposed, in order to achieve a more practical purpose. Utility Model Content

[0026] The basic movable roller 11 method is adopted, and multiple groups of movable rollers 11 drive the melt-blown non-woven fabric to be transmitted. The movable rollers 11 are staggered up and down to continuously transmit the melt-blown non-woven fabric, and the melt-blown non-woven fabric is dried in the sealed processing box 1 and receives heat transfer from the top drying heater 7, so that the melt-blown non-woven fabric is in a dry state during the transmission process, thereby increasing the expansion coefficient of the melt-blown non-woven fabric, thereby facilitating the subsequent electrostatic electret operation process;
