Abstract

The invention allows the working range to be extended by increasing the duration of dose dispensing. In the intermediate tank 4, the intake end 5 of the siphon tube is fixed, connected through the flexible tube 7 with its outlet end 10. When the measuring tank 3 is filled with liquid, the tank 4 will float up to the stop in the stopper 6. At the same time, the liquid will begin to flow through the auxiliary pipeline 8 and end 10 siphon tube in product capacity. The ratio of the flow rate of the liquid supplied to the container 3 and flowing out of it is provided by the regulators, tori 1, 9. The outflow of liquid from the dispenser stops when the level of the liquid in the container 4 coincides with the inlet end of the intake end 5, accompanied by air entering the siphon. 4 il.

Description

The invention relates to instrumentation and can be used in food, chemical and other areas of industry.

The purpose of the invention is to expand the operating range by increasing the duration of the dose.

FIG. 1 shows a siphon dispenser; FIGS. 2-4 show dispenser cycles.

The siphon metering device has a measuring tank 3 connected through the flow controller 1 to the supply pipe 2, an intermediate tank 4 installed in it, in which the intake end 5 of the siphon tube and the height-adjustable stop 6 of the upper position of the intermediate tank 4 are placed, a flexible tube 7 auxiliary pipe 8 with an adjusting regulator 9 p, the intake end 5 of the siphon tube is rigidly fixed in the lower part of the intermediate tank 4 and connected via a flexible tube 7 to the outlet end of the 10 upper part of the siphon tube, which It communicates with the bottom of the vessel 3 dimensional auxiliary duct 8 with flow regulator 9,

Through the flow regulator 1, the liquid 2 enters the flow line 3 into the measuring tank 3 and fills it. At the same time, due to the buoyancy force of Archimedes, the empty intermediate tank 4 emerges, and the intake end 5 of the siphon tube, which is rigidly connected to the intermediate tank 4, rotates clockwise (Fig. 2). In parallel, the auxiliary pipeline 8 is filled with liquid through the regulator 9 consumption

Upon reaching the level of the liquid in the measuring tank 3 of the upper part of the siphon tube (level I, fig. 2), the outflow of liquid from the measuring tank through the auxiliary pipeline 8 and the outlet end 10 of the siphon tube into the product tank begins. At the same time, the outflow of a fluid occurs slowly, and then, when the level of a fluid rises, the fluid in the measuring tank becomes faster and faster. The flow rate of the fluid supplied to the measuring tank 3 must be greater than the flow rate of the fluid flowing through the auxiliary pipeline 8, the specified condition is ensured

The system is adjusted accordingly using flow regulators 1 and 9.

When the measuring container 3 is filled with liquid, a moment comes when the intake end 5, together with the intermediate tank 4, stops with the stop 6, the intermediate tank 4 is gradually filled with liquid. When the moment of weight of the intermediate tank 4 with the liquid in it and the weight of the intake end 5 is greater than the moment of the buoyancy force of Archimedes, the intermediate tank 4 quickly sinks to the bottom of the measuring tank. Immersed, it draws the intake end 5 behind itself and turns it counterclockwise (FIG. 4). From the moment the intermediate tank 4 is lowered, the liquid enters the intake end 5, through which the rapid outflow of fluid from the measuring tank 3 begins to the commodity tank.

Since now the flow rate of the liquid flowing into the measuring tank 3 through the supply pipe 2 is less than the flow rate of the liquid flowing out of the siphons, the liquid level in the measuring tank 3 is lowered. There comes a time when the level of the liquid coincides with the upper edge of the intermediate tank (level III, fig, 4),

Upon further discharge of the liquid, its level in the intermediate tank 4 decreases. The upper edge of the intermediate tank 4 in this case is a retaining wall through which the liquid flows from the measuring tank 3 to the intermediate tank 4,

Although all liquid flows into the intermediate tank from the measuring tank 3, flowing out per unit time 5 from the supply pipe 2, the rate of decrease of the liquid level in the intermediate tank 4 is large enough. As the volume of fluid in intermediate tank 4 decreases, there comes a moment when the total weight of intermediate tank 4, the fluid in it, as well as intake end 5 will be less than the buoyant force Arghimedes acting on the intermediate tank 4 and the intake end 5, therefore the intermediate tank 4 floats.

It is above the level of the liquid in the measuring container 3. The separation of the liquid in the dimensional and intermediate containers occurs. Since now the liquid from the measuring tank 3 does not flow into the intermediate tank 4, only the liquid that is in the intermediate tank 4 flows through the siphon. For this reason, the liquid level in the latter quickly lowers. As soon as the level of the liquid and the intermediate tank 4 coincides with the inlet end of the intake end 5, air from the atmosphere enters the siphon and the outflow stops.
