Description

The invention relates to metering devices and can be used in process streams with irregular consumption in mining, metallurgical, chemical, and other industrial areas.

The purpose of the invention is to increase the dosing accuracy and expand the range in the direction of increasing maxi -.-; Maximum dose of dosing.

In the drawing. The image of the proposed device., General view,

The device for dispensing liquid and volatile materials contains a capacitance 1, divided into two compartments 2 and 3. Capacity 1 begins freely on an axis mounted on frame 4, on which electromagnets 5 and 6 are installed, electrically connected to current regulators 7 and 8. The electromagnets are supported on the stop 9, installed on the ligand for the section of the tank 1. A pipe 10 is located above the tank. The pipe is set down by tank I so that its axis and the axis of rotation I1 of the tank are in the same vertical plane.

Electromagnets 5 and 6 contain, respectively, each metering windings 12 and 13, pull windings 14 and 15, windings 16 and 17, which serve as a signaling device. Signal windings 16 and 17 are connected to the inputs

ABOUT

a control unit 18 comprising two chains of amplifier 19 in series, a relay 20, a power supply circuit 21, the output of which is connected to the pull winding 14 and an amplifier 22, a relay 23, a power supply circuit 24, the output of which is connected to the pull winding 15..

The device works as follows.

With the help of current regulators 7 and 8, the current is set in the metering windings 12 and 13 of electromagnets 5 and 6, which ensures that capacitance 1 is held in the extreme positions until the compartments 2 or 3 are filled.

The source material, entering through the inlet, begins to fill, for example, compartment 3. Electromagnet 5

is in the position of contact with the control unit 55; the control unit contains two forces 9 due to the magnetomotive force of the metering winding 12. When a given weight is reached, the value of which is determined by the magnetomotive force

bodies, two time relays and two power circuits for the traction windings, with the traction winding of the first electromagnetic stop limiter after

metering winding 12 and is regulated by the current regulator 7, equality of opposing forces occurs. Capacity

1 due to the kinetic energy of the accumulated mass in compartment 3 begins to move, and the opposite compartment

2 begins to fill. When otrshe electromagnet 5 from the stop 9 with the signal winding 16 receives a signal

in control block 18. Signal effort. In the amplifier 22 and through the time relay 23, it turns on the power supply 24 of the traction winding 15. At this time, the capacitance rest 9 approaches the electromagnet 6, the tractive force of which due to the simultaneous induction of the magnetomotive force of the metering winding 13 and the trap winding 15 is sufficient to pull compartment 2 partially filled with mass. Upon reaching contact between the electromagnet 6 and the stop 9, the time relay 23 after a predetermined time (which is selected depending on the maximum performance of the device) turns off the power to the traction winding 15 and the capacitance is held in this position behind. an account of the force of the metering winding 13, the current of which is adjusted by the current regulator 8. When the compartment 2 is filled with a mass up to a given weight, the emphasis is removed from the electromagnet 6 and the capacitance 1 begins to rotate. The signal winding 17 gives a signal to turn on the power supply to the traction winding 14. Next, the operation cycle repeats.
