SU149237A1 - Lime milk flow meter, for example, for sugar mills - Google Patents

Description

The invention relates to lime milk flow meters, for example, for sugar factories, based on measuring the level of a liquid flowing from a vessel through a drain slot. The known flow meter operating on this principle contains a chamber with a receiver for milk of lime, a partition that does not reach the bottom, a measuring compartment separated from the chamber by a calibrated slit, and a measuring device. Due to the introduction of sand and lime (contained in lime milk), this flow meter is not reliable enough during operation in sugar factories.

In the proposed flow meter of a similar purpose, conditions are created to prevent it from being carried by lime and sand, thereby increasing the reliability of operation.

To this end, the receiver contains labyrinth fins; the chamber in front of the slit is tapered, provided with a bottom tilted toward the slit, the lower edge of the slit is located at the bottom of the chamber, and the measuring device is designed as a flap on the horizontal axis of the valve deflected by the effect of lime milk flowing from the slit.

To prevent sand and lime from depositing on the measuring device itself and on the gap from the measuring section, a shower device can be mounted in the flow meter.

FIG. 1 and 2 schematically in two projections depicts the proposed flow meter; in fig. 3-form u, spruce flow meter.

The flow meter comprises a chamber 1 with a receiver 2 for lime milk, a measuring compartment separated from the chamber by a calibrated slit 4, and a measuring device. Receiver 2 is formed by a partition 6 that does not reach the bottom 5 and contains labyrinth fins 7. Chamber 1 is made narrowed before slot 4 (FIG. 2), and its bottom 5 is angled JMb 149237-2 -

not in the direction of the slit 4. The bottom edge S of the latter is located at the bottom level 5-

The measuring device is made in the form of a swinging on the horizontal-axis 9 of the flap 10, deviating under the action of the resulting lime jet of milk.

Dushchiru 15, u, its fixture // mounted in the measuring compartment of the STI makes it possible to prevent the deposition of sand and lime on the building itself and on the slot from the side of the measuring compartment. When the flow meter is turned on, a stream of milk of lime, passing at a considerable speed in the narrowed chamber /, flows out of the slit 4 in the form of a jet and deflects the shutter 10 by an angle proportional to its consumption. Secondary appliance 12 shows lime milk consumption

A prototype flow meter tested at Ust-Labinsk sugar factory with positive results.

Claims (2)

1. Lime milk flow meter, for example, for sugar factories, based on measuring the level of liquid flowing from the vessel through the drain slot, containing a chamber with a receiver for lime milk, a partition not reaching the bottom, a measuring compartment separated from the chamber by a calibrated slit, and a measuring device, characterized in that, in order to prevent sand and lime from entering and making the flow meter more usable, the receiver contains labyrinth ribs, the chamber in front of the slit is narrowed, The bottom is inclined towards the slit, the lower edge of the slit is located at the level of the bottom of the chamber, and the measuring device is made in the form of a swinging on the horizontal axis of the shutter deviating under the action of the milk of lime flowing out of the slit. 2. A flow meter according to claim 1, characterized in that, in order to prevent sand and lime from depositing on the measuring device itself and the gap from the measuring compartment, a shower device is mounted therein.  -G Fig fI In production // V // /
