Description

The invention relates to liquids spill devices using a series of vertically displaced measuring tanks supplied from a common pipe connected to an auxiliary barrel, the level of liquid maintained by a float valve, and emptied by pressing the mouths of the filled dish onto funnels joined to drain valves.

In the proposed device, the weight amount of the liquid to be dispensed in the dispensing vessels is set by the metering cylinder, moved vertically in the direction opposite to vessel movement, and serves for pouring onto the weighing pan the amount of liquid to be dispensed and corresponding to filling the dispensing vessels.

In the schematic drawing of FIG. 1 shows a general view of the device; FIG. 2 is a top view of a part of it.

The liquid to be bottled is filled in the tank /, to which is connected via pipe 4 an auxiliary tank 2 to the float 5. The outlet b of the pipe 4 is covered with a valve connected to the float regulating the liquid level in the tank 2 to which the pipe 7 with openings is attached 3, located against the slots 10 in the walls of the dispensing vessels 9 connected to each other. Vessels 9 can be moved vertically to ipravs. 12 when the adjusting screw // is rotated and with the help of a rack mounted on the extreme vessel, which is in engagement with the gear 8, communicate the reverse movement of the metering cylinder 13. In the lower part of the vessels 9 are drain valves 19 associated with funnels / 5, when pressed by the mouth of the filled dish, liquid flows out of the vessels 9.

To spill the liquid in doses by weight, preliminarily the screw // lifts the vessels 9 so that the cylinder 13 lowers and its edge coincides with the outlet 16 of the pipeline 7. When the cylinder 75 is filled with liquid, its valve 14 rotates until it coincides with the hole 17 telling the cylinder pipe 18, facing in the direction located under the cylinder of the scales. When vessels 9 are lowered and at the same time cylinder 13 is being lifted, the liquid from the latter will be poured onto the scales and in the same amount, each of the vessels 9 will be filled from the pipeline 7. Lowering

the next stops when the amount of liquid required by weight that has poured out from the cylinder 75 is on the scale pan. In this case there will be a volume of liquid in each of the vessels 9. an equal in volume liquid poured out and weighed from the metering cylinder 13. Next, vessels are placed under the vessels 9 and the measuring tanks are emptied through the drain valves when the mouths of the dishes are pressed on the funnels 75.

The subject of the patent.

A device for dispensing a liquid in doses by weight, using vessels transported vertically and fed by a liquid.

from the common pipeline and emptying when the drain valves are pressed by the mouths of the filled dishes, the auxiliary tank with automatically maintained liquid level through the float valve, characterized in that, in order to establish the required dose of liquid in weights, the device is equipped with verticals in the reverse directions with the draft vessels 9 and the dosing cylinder 13, which serves for pouring upwards through the opening 17 to the weighing pan (not shown x) the amount of fluid to be bottling.
