Abstract
The utility model provides an induction style metal articles metering device, comprising a hopper, and conveying belts which are arranged under the hopper. The utility model is characterized in that exist openings of the hopper are provided with an induction system of materials receving, which makes electrical inductance of metallic minerals changed in the process of materials receiving; the electrical inductance detectors are used for obtaining the weight of the metallic minerals. The characteristics of detecting objects are used for making measurement accurate and reliable. The utility model has the advantage of high work efficiency, which benefits for the keep of the constant of delivery volume of minerals, and benefits for dynamic management and monitoring for automated production.
Description
The utility model relates to a kind of Weighing device, and especially a kind of inductance value change-detection that causes when utilizing metal object to pass the magnetic field boundary goes out the inductance type measuring apparatus of metal object weight.
Reality can only be measured the conveying total amount of the transported material on the conveying belt in producing, to the unexecuted metering of the blanking amount of each funnel, can not implement monitoring to the blanking quantity of each funnel simultaneously, therefore, be difficult to realize the constant delivery and the monitoring of transported material, can not adapt to orderly, the stable production and the needs of high speed development.
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of inductance type metal object measuring apparatus of carrying out weighing in each funnel blanking process simultaneously is provided, so that constant throughput helps the blanking amount is implemented monitoring.
The technical solution of the utility model is: it comprises hopper, is located at the conveying belt of funnel bottom, it is characterized in that being provided with in the exit of hopper the blanking induction installation of belt coil.Described blanking induction installation is square or cylindrical induction tube, so that metalliferous material passes this induction tube.Described blanking induction tube is provided with coil, and the coil two-end-point is electrically connected with inductive detector, so that produce the induced magnetism field boundary, when metalliferous mineral passes through this induced magnetism field boundary, promptly cause the variation of inductance value, after by inductive detector above-mentioned changing value being handled, can obtain the weight of metalliferous mineral.Described inductive detector comprises inductance signal processor, signal amplifier, signal converter, wherein signal processor is made of integrated circuit and the resistance, the electric capacity that are attached thereto, and input end is electrically connected with the coil that blanking is responded on the tube, so that the inductance conversion of signals is become the full sized pules signal.Signal amplifier is made of amplifier integrated circuit and the resistance that is attached thereto, electric capacity, diode, and its input end is electrically connected with the output terminal of signal processor, is used for the pulse signal from the signal processor is amplified.Signal converter is made of A/D integrated circuit and the resistance that is attached thereto, electric capacity, triode, its input end is electrically connected with the output terminal of signal amplifier, output terminal is electrically connected with display and primary controller, after being used for pulse signal with amplifier and converting gravimetric value to, show by display, and send the primary controller statistics and carry out constant delivery control.
The utility model compared with prior art has following advantage and good effect: owing to be provided with the blanking induction installation of belt coil at each discharging opening place, hopper bottom, making metalliferous mineral produce inductance value in the blanking process changes, obtain the weight of metalliferous mineral again by inductive detector, utilize the characteristic of detected object to make metering accurately, reliably, and high efficiency, help keeping the constant of mineral operational throughput, help the dynamic management and the monitoring of automated production.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the circuit structure diagram of the utility model.
The specific embodiment that provides below in conjunction with accompanying drawing is described further the utility model, is not limited to this but hold within the utility model.
Among the figure, 1 is hopper, and 2 are blanking induction tube, is square or cylindrical, and it is arranged at hopper discharging opening place, and it is provided with coil 3, and the two ends of coil 3 are electrically connected with inductive detector 4, and 5 is conveying belt, is used for the metalliferous mineral that conveyor hopper falls.
Signal processor in the inductive detector 4 is by 0091 integrated circuit and resistance, electric capacity constitutes, wherein the two ends of coil 3 connect IN end and ground end respectively, the IN end is connected to 16 and 15 pin of integrated package 0091 by resistance R 9,4 pin ground connection of this integrated package, 9 pin are by resistance R 4, R2 links to each other with 5 pin, be used for the inductance conversion of signals is become the full sized pules signal, 12 pin link to each other with 5 pin by R3, be connected to 2 pin of amplifier integrated package 356 again by R10, so that above-mentioned pulse signal is delivered to 356 to be amplified, 356 3 pin pass through R22, R23 ground connection, 6 pin are connected to 7 pin of A/D integrated package 331 by R21,356 2 pin are connected to 331 1 pin, being used for that the signal after amplifying is delivered to 331 changes, 331 1 pin, be connected with capacitor C 4 between 7 pin, 4 pin ground connection, 2 pin pass through R13, R12 ground connection, 6 pin pass through C2, R15, R16, R17 links to each other with 5 pin, again by C3 ground connection, so that convert pulse signal to gravimetric value, 331 3 pin are output terminal, are used for that gravimetric value is delivered to display and show, deliver to primary controller simultaneously and monitor.
