Belong to the electrostatic on material conveying pipe inwall, the transmitting coil of meeting severe jamming metal detector and receiving coil
Normal work, causes metal detector to survey erroneous judgement by mistake, frequently reports to the police or just fail to report, can draw time serious
Ignition calamity, the present invention carries out innovative design to material conveying pipe, by epoxy resin and graphite powder mixed preparing
Material makes non-metallic material conveyance conduit, owing to being evenly distributed on the graphite of material conveying pipe bore area
Powder is radio frequency thing, and it has good electric conductivity, when material is at the bore area of material conveying pipe
During flow at high speed, discharge in time because of fricative electrostatic energy at bore area, electric spark will not be produced,
More will not produce unexpected interference electromagnetic wave, thus ensure that transmitting coil and receiving coil are being done without electromagnetism
Disturb and normally work under environment, it is ensured that the normal work of whole metal detecting device, improve metal detector
Detection accuracy rate, eliminate all kinds of potential safety hazards caused because of electrostatic.
