Electrostatic elimination device

Abstract

The invention discloses a static electricity eliminating device which comprises at least two conductive materials and at least one static electricity eliminating circuit. The conductive materials areisolated from each other and attached to the outer wall of an insulating hollow pipeline, the conductive materials are overlapped in the radial direction of the insulating hollow pipeline, and electrostatic charges are accumulated on the insulating hollow pipeline and form electrostatic voltage on the conductive materials. The electrostatic elimination circuit is electrically connected with the conductive material and disconnected with a grounding end, and the electrostatic elimination circuit receives and eliminates electrostatic charges through the conductive material so as to reduce electrostatic voltage. According to the utility model, extremely high electrostatic voltage is effectively dissipated from the insulating hollow pipeline, and noise interference of the grounding end is avoided.

Description

technical field [0001] The present invention relates to an eliminating device, and particularly relates to a static eliminating device. Background technique [0002] Static electricity is a natural phenomenon in nature. Two objects that are originally electrically neutral, after friction, will produce electron transfer, resulting in the generation of static electricity. In the transmission pipeline of dielectric material, such as plastic pipeline or rubber pipeline, due to the friction between the transmission liquid and the transmission pipeline wall, it is easy to generate static electricity, which will cause some hazards. For example, when the liquid being transferred is flammable, static electricity may cause sparks to occur, causing the flammable liquid to catch fire or even explode. Static electricity may also directly damage the pump or pump (PUMP) in the pipeline. In the pipeline of semiconductor manufacturing process, if the solvent in the pipeline has static ele...
