An apparatus for online Detection of Magnetic Resonance signals from a Target material in a Mineral slurry

摘要

Provided is a device for online Detection of Magnetic Resonance signals from a Target material in a MINERAL MUD, comprising (i) an electrically Conductive housing.(ii) an electrically non-conductive pipe (ENC) to allow the flow of a Mineral slurry through the Housing and configured to electrically Conductive,(iii) a First Primary Coil configured to encompass a Section of the electrically non-conductive Pipe inside the casing.Each Primary Coil defines a measurement area (iv) a Condenser Unit coupled to a primary Coil Terminal of each respective where we Select a value of the value of each Unit of COndensador, so that resonance in series of a primary Coil is formed close to the value of the magnetic resonance frequency of the target material.(V) a RF Transmitter that works to convey a Signal to one or More Electrical Networks of excitation coils,Where an operating frequency of the transmitter Frequency is approximately equal to the magnetic resonance frequency of the target (VI) at least a First Drive CoilAnd a Network of Associated Electrical excitation coils,Where the amount of excitation coils is equivalent to the amount of primary coils and where each Network and Associated Electrical Drive Coil of excitation coils are positioned in relation to aA primary Coil magnetically coupled to the primary Coil to the Drive Coil Impedance (vii) a Monitor coupled to each Grid of excitation coils and functionTo measure the input Impedance of the Electric Network of Complex excitation coils (viii) and a RF receiver adapted to receive from the front or from each Electric NetworkOf excitation coils, magnetic resonance signals from the target, the RF receiver forming a Signal output of the signals detected.
