Abstract

Usage: dispensing fluid. SUMMARY OF THE INVENTION: Liquid flows through a supply pipe into a measuring tank. When the siphon is turned on, the tank is empty. The dose is adjusted by changing the position of the suction end of the siphon relative to the bottom of the measuring tank. To do this, with the help of a flywheel and a shaft, a downward inclined pipe inclined to the horizon is rotated about its axis. The dose is set on a scale that is fixed on the wall of the container, according to the pointer mounted on the shaft, t s.p. f-ly, 1 ill.

Description

The invention relates to instrumentation and can be used in chemical, chemical, pharmaceutical, perfumery and other industries for dividing liquids into equal volumes, as well as in automation systems when it is necessary to dispense doses according to a given program.

An object of the invention is to provide dose control over a wide range.

This goal is achieved by the fact that a seal is introduced into the device, the downstream siphon nozzle being placed in the measuring tank at an angle to the horizontal, passed through the bottom of the measuring tank and installed in it by means of a seal that can rotate about its axis. This goal is also achieved by the fact that a shaft with a flywheel and an arrow with a scale are inserted into the device, the shaft being installed along the axis of the downstream pipe, fastened to the hump

siphon and passed through the wall of the measuring tank, on the outside of which a scale is installed, and the arrow is mounted on the shaft.

The drawing shows a diagram of the dispenser.

The dispenser consists of a measuring tank 1, supplying the piped liquid to be dosed 2, an adjusting device 3, a siphon 4, a flywheel 5, a shaft 6, an arrow 7, a scale 8, a sleeve 9, a seal housing 10, a pressure ring 11, screws 12 and a seal 13.

The purpose of the parts of the proposed dispenser is as follows. In the volumetric container 1, there is a dose of liquid before it is drained into the commodity container (the commodity container is not shown in Fig. 1), the dosed liquid is supplied to the measuring tank 1 through the supply pipe 2. Using the adjusting device 3 (for example, a tap), the flow rate is changed dosing liquid at the moment of dispenser setting. Through siphon 4 there is a liquid overflow from the measuring tank 1 into the product (L

new capacity. Using the flywheel 5, shaft 6, the siphon 4 is rotated. Arrow 7 indicates the dose. On a scale of 8, you can determine the dose. The sleeve 9 is the supporting bearing of the shaft 6. Parts 10-13 provide a seal warning the leakage of liquid from the measuring tank 1 at the passage of the descending section of the siphon 4.

The principle of operation of the siphon is as follows. When you open the adjusting device 3 through the pipe 2 into the measuring tank 1 comes dosed liquid. As soon as the level of the free surface of the liquid in the volumetric container 1 rises to the upper point of the hump of the siphon 4, the siphon 4 is activated, i.e., liquid will flow through it from the volumetric container 1 into the commodity container. The flow rate of liquid entering the volumetric tank 1 is greater than the flow rate of liquid flowing from the volumetric tank 1 through a siphon 4, therefore, the level of the free surface of the liquid in the volumetric tank 1 decreases. As soon as the level of the free surface of the liquid in the measuring tank t coincides with the end of the ascending section of the siphon 4, air will enter the siphon 4 from the atmosphere and the outflow from the measuring tank 1 will stop. Then the dispenser operation cycle will be repeated. Turn the handwheel to change the dose.

7. At the same time, the siphon 4 will rotate by a predetermined angle, due to which the volume of liquid in the measuring container to be drained for a given dosing cycle will change.

Advantages of the proposed dispenser: the DII-71 siphon dispenser has wide dosage control limits, the convenience of dose adjustment, the compactness of the dispenser (siphon 4 is inside a measuring container)

simplicity of the dispenser device and its reliability.

Claims (2)

1. The dispenser containing the connected a measuring tank with a siphon to the supply pipe, characterized in that, in order to ensure dose adjustment in a wide range, a seal is introduced into it, and the downward pipe the siphon is placed in the measuring tank at an angle to the horizon, passed through the bottom of the measuring tank and installed in it by means of a seal and can rotate about its axis. 2. The dispenser according to claim 1, from which the shaft is inserted and a shaft with a flywheel and an arrow with a scale are inserted into it, the shaft being installed along the axis of the downstream pipe, fastened to the siphon hump and passed through the wall measuring capacity, on the outside of which a scale is installed, and the arrow is fixed on the shaft. fifteen Proofreader N.Keshel
