Abstract

The invention relates to an electrostatic electret device for melt-blown cloth. The electrostatic electret device is composed of an electric box, a rack, an upper electrostatic generator, a lower electrostatic generator, dischargers, an insulating plate, a hand wheel, a nylon plate, a discharge wire and an insulating shell. The electric box is mounted on the rack, a special high-voltage power supply is adopted in the electric box, a digital control manner is adopted, full-abnormal slow start is achieved, and the nanosecond arc discharge response capability is achieved, so that the upper electrostatic generator and the lower electrostatic generator can stably and reliably discharge and load charges; and the upper electrostatic generator and the lower electrostatic generator are arranged onthe rack and are insulated through the insulating plate, the plurality of single dischargers are arranged on the upper electrostatic generator and the lower electrostatic generator, and the dischargers can uniformly discharge to load charges to the melt-blown cloth. The electrostatic electret device has the beneficial effects that the melt-blown cloth electret charge distribution effect can be improved, and the problems of non-uniform electret charge addition and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of melt-blown fiber nonwoven fabric machinery and equipment, and in particular relates to an electrostatic standing device for melt-blown fabric. Background technique [0002] Adding static electricity to the melt-blown cloth will greatly improve its filtration efficiency, because its charge imbalance can effectively absorb charged particles in the atmosphere. If no static electricity is added, the particle filtration efficiency of the melt-blown cloth will be greatly reduced, and the filtration efficiency of the masks made will also be reduced. It will be unqualified because of this, and the electrostatic standing level of the melt blown cloth is one of the important factors for the melt blown cloth to meet the standard. At this stage, the electrostatic standing devices on the market are mainly based on single-filament static electricity, which cannot be used to charge the melt-blown material well, and the ...
