[0020] Please refer to Figures 1 - 2 , in the embodiments of the present invention, an on-line monitoring device for magnetic separation tailings includes:

[0021] A housing 1 for protecting the components required for on-line monitoring of magnetic separation tailings;

[0022] A medium pipe 101 is inserted through the inside of the housing 1. An alloy coil 103 is evenly wound on the outer side of the medium pipe 101 and inside the housing 1. One side of the alloy coil 103 is electrically connected to a reference voltage 2, and the other side of the alloy coil 103 is electrically connected to a converter 3. The side of the converter 3 away from the alloy coil 103 is electrically connected to a temperature and humidity compensation chip 4. A junction box 104 is electrically connected to the top of the housing 1. The reference voltage 2, the converter 3, and the temperature and humidity compensation chip 4 are all located inside the housing 1.

[0023] In this embodiment, the on-line monitoring device for magnetic tailings mainly consists of a wear-resistant medium pipe, a solenoid coil, and a converter. The corundum-lined pipe has high hardness and good wear resistance. The solenoid coil is made of a copper-silver alloy material with good electrical conductivity. When a magnetic substance passes through the coil, the inductance changes significantly.

[0024] (L - inductance, μ0 - magnetic permeability of vacuum, μ - magnetic permeability of magnetic substance, l - coil length, V - volume of magnetic substance).

[0025] Please refer particularly to Figure 1 and 2 , the converter 3 uses an imported inductance detector to detect minute inductance changes. The temperature and humidity compensation chip 4 is used to reduce the influence of environmental factors and keep the detected data accurate.

[0026] In this embodiment, the environmental temperature is 0 - 40°C, the measurement range is 0 - 50 g / L, and the measurement accuracy is 0.2 g / L.

[0027] Please refer particularly to Figure 1 and 2 , on both sides of the outside of the medium pipe 101, flange plates are provided, and a plurality of groups of jacks are evenly arranged on the outside of one side of the flange plates. The flange plates and jacks are used to facilitate the connection with the external conveying pipe.

[0028] Please refer particularly to Figure 1 and 2 , the medium pipe 101 is made of a wear-resistant material 102, and the wear-resistant material 102 is a bimetal composite material. Due to its good electrical conductivity, when a magnetic substance passes through the coil, the inductance changes significantly.

[0029] The working principle of the present utility model is as follows: During detection, based on the principle of electromagnetic induction, a solenoid coil is arranged on the outer circle of the measuring conduit. A reference voltage 2 is given. When a magnetic substance passes through the magnetic field of the solenoid coil, an additional magnetic field is generated, thereby generating an additional voltage. Since the additional voltage is proportional to the volume of the magnetic substance, the content of the magnetic substance in the medium is calculated by detecting the voltage variable. Among them, the temperature and humidity compensation chip 4 is used to reduce the interference caused by temperature and humidity in environmental factors, and then the sampling composite material is used to improve the detection accuracy, so as to accurately measure the content of magnetite powder in magnetic tailings, thereby improving the sorting effect of the real-time monitoring magnetic separator and controlling the coal washing production to reduce the loss of the medium, thereby improving the utilization rate.
