Referring to fig. 1, the present utility model provides a liquid level interface measuring instrument device 100, and the liquid level interface measuring instrument device 100 is mainly used for accurately measuring a liquid level interface in a flotation process.

Specifically, the liquid level interface measuring instrument device 100 includes a measuring device 101, an anti-interference device 102, a traction replacement device 103, and a cleaning device 104. The measuring device 101 is arranged at the upper part of the disturbance preventing device 102 and is used for acquiring a liquid level interface in the flotation process. The anti-interference device 102 is arranged at the lower part of the measuring device 101 and is used for reducing the measuring error caused by liquid disturbance in the flotation process, thereby improving the precision of the measuring device 101. A traction replacement device 103 is connected to the upper part of the measuring device 101 for replacing the measuring instrument 106 in the measuring device 101. The cleaning device 104 is disposed on one side of the measuring device 101, and is used for cleaning the measuring device 101 to ensure the normal operation of the measuring device 101.

In the prior art, for example, radar ultrasonic type level measuring devices. In the device, the height of the liquid level is obtained by calculating the time of ultrasonic wave return to the probe by utilizing the reflected signals of radar and ultrasonic wave, but the reaction is not as expected in the actual use process of mine projects, and the measurement becomes difficult to realize because the ore pulp of the flotation tank has more foam and obvious clutter emission.

Also, for example, a radio frequency admittance interface meter. In the device, the type of instrument reflects the interface position through the impedance characteristic of the measured medium, but the device hardly reflects the real position of the interface between the foam layer and the ore pulp completely only through one parameter of conductivity, and the on-site practical application error usually has an error of about tens of centimeters or one meter, so that the automatic control requirement of the flotation tank is hardly met.

Also, for example, a capacitive interface meter. In the device, the instrument works according to the cylinder capacitor principle or works by adopting the radio frequency capacitor principle, but the measurement cannot be continuous due to the characteristic of easy scaling of ore pulp media, and the cleaning difficulty is high and the instrument is easy to damage, so the instrument is rarely used in mine projects.

In the utility model of the present application, when measuring the liquid level interface, the disturbance rejection device 102 is first fixed to the flotation machine, and the measurement device 101 is put into the flotation machine. According to the target minerals and the scaling rate, the traction lifting replacement measuring probe and the cleaning frequency are determined, so that the purpose of continuous monitoring is achieved, and further, the flotation process engineering can be effectively monitored, and the quality of the minerals can be effectively controlled.

In addition, the liquid level interface measuring instrument device 100 in the application adopts the most common buoyancy measuring method, and measures the related liquid level interface by utilizing the displacement of the metal connecting rod when the metal floating ball and the buoyancy of the liquid are balanced, so that the principle can greatly reduce the overall cost of the system.

Further, the tamper device 102 includes a tamper bucket 105, and the tamper bucket 105 is disposed at an upper portion inside the tamper device 102.

In this embodiment, the tamper bucket 105 may be used to reduce disturbances in the flotation process, thereby ensuring the measurement accuracy of the measurement device 101.

Further, the tamper-proof basket 105 includes seepage holes and/or seepage grooves (not shown in the figures) for passing the target beneficiation media during flotation.

Further, the measuring device 101 comprises a plurality of measuring instruments 106, the measuring instruments 106 being used for measuring the liquid level interface in the flotation process.

In the present embodiment, the measuring device 101 includes a plurality of measuring meters 106. Wherein two or three gauges 106 constitute a group. In use, one set of gauges 106 is in standby while measurements are being taken, with the other gauges 106. To improve the usability of the fluid level interface gauge apparatus 100 and reduce the cost of the gauge 106, a mechanical float gauge may be selected for group adaptation.

Further, the level interface gauge apparatus 100 includes a tamper tube (not shown in the figures) for reducing disturbance.

Further, the anti-tamper device 102 comprises a fixing bracket (not shown in the figure), which is arranged at the periphery of the anti-tamper device 102 for fixing the anti-tamper tube, thereby reducing disturbance.

Further, the measuring device 101 comprises a transmitter (not shown in the figures) for acquiring the displacement distance of the connecting rod and performing the level measurement during flotation.

Further, the measuring device 101 comprises a tray 107, and the tray 107 is used for throwing the standby measuring instrument 106 into the measuring medium in a rotating manner.

Further, the measuring device 101 comprises a measuring float ball 108, wherein the measuring float ball 108 is used for floating in a measuring medium during flotation, so that a liquid level interface is measured through a connecting rod on the measuring float ball 108.

Further, the traction replacement device 103 includes a traction motor (not shown in the drawings) for pulling the measuring instrument 106 in the measuring device 101 to perform replacement of the measuring instrument 106.
