Abstract

The invention relates to equipment for the dosing of bulk materials. The purpose of the invention is to increase reliability and accuracy of positioning. The dispenser contains a vibration-mounted hopper 1., under which are pivotally fixed measuring chambers 6 and 7, made in the form of a sector 8 connected with an oscillating motion drive 9. The dispenser is equipped with a warning device, 11 of material, the sensor 12 is fixed in the receiving tank 13, stops 16 mounted on the bunker, promptings for opening 14 and 15 valves 4 and 5. On valves 4 and 5 are fixed with the possibility of alternate interaction with the stops 16 and drivers for opening 14 and 15, shanks 17 and 18, measuring chambers 6 and 7 with the possibility of measuring the volume, and the dampers 4 and 5 are compressed in the direction of closing by springs 20. The shank of the measuring chamber 6 or 7, which came up under the load, hit the stop 16 of the bunker 1, facilitates the loading of this measuring chamber with the dosing material from the bunker 1 and the discharge of the dose from the second dimensional camera. 1 il. f (L

Description

P

The invention relates to equipment for the dosing of bulk materials.

The purpose of the invention is to increase the reliability and accuracy of dosing.

The drawing shows the proposed dispenser.

The dispenser contains a hopper 1, under the outlet opening 2 of which, with the smallest possible clearance on axis 3, hingedly fixed measuring chambers 6 and 7 equipped with flaps 4 and 5, made in the form of a sector 8 associated with an oscillating movement actuator 9, which is connected to the unit 10 controls The dispenser is equipped with a signaling device 11 for the presence of material, the sensor 12 of which is fixed in the receiving tank 13, installed under Lecturer 8. On flaps A and 5, they are fastened with the possibility of alternating interaction with the boosters 14 and 15 of opening flaps 4 and 5 and mounted on the bunker 1 by the stops 16, the shanks 17 and 18. The measurement chambers 6 and 7 are made with the possibility of volume change due to the rotary pre-walls 19, and the flaps 4 and 5 are pressed in the direction of closing by the springs 20 The bunker 1 is installed with the possibility of vibration due to the fact that the roles interact 21 with a curved bearing surface 22, described by a radius taken from the center of rotation of sector 8, axis 3. The movement of the hopper 1 is limited by the springs 23 and the lugs 25 that interact with the projections 24 of the bunker 1.

The dispenser works as follows.

At the command of the control unit 10, the sector 8 under the influence of the actuator 9 begins to oscillate from one extreme position to the other. At each extreme position, one dimensional chamber 6 or 7 is filled with the material being metered, while the other is empty at this time. This happens as follows (the moment shown in the drawing).

The tail of the 17-dimensional camera 6, suitable for loading, blows on

the stop 16 of the bunker 1, and the shank 18 of the empty chamber 7, when it hits the opening booster 15, opens the flap 5, opening the outlet to the dosed material, which under the influence of labor (by inertia) and under the influence of the gravitational force pulls out of chamber 7.

Under the action of impact on the stop 16, the hopper 1 begins to vibrate, intensively feeding the material to be dosed into the measuring chamber 6. This process repeats with each turn of sector 8,

alternately for each measuring chamber.

Dosing material, poured from the measuring chambers 6 and 7, enters the receiving tank 13, where it is in contact with the sensor 12 of the detector 11 the presence of material. The signal from the sensor 12 enters when a metered material passes through it. In case of violation of the specified rhythm of signal arrival

The detector 11 of the presence of the material gives an alarm, and through the block 10 of the control sends a command to shut off the dispenser. J
