Abstract

The present invention relates to a dosing balance having a measuring container (1) for bulk materials or liquids, at least the measuring container (1) being mounted on weighing elements (8). To make it possible to save space and, whilst ensuring a compact design, to dose any bulk materials or liquids exactly with such a balance, it is proposed, according to the invention, that a second measuring container (3) be arranged on the measuring container (1), and that there be provided for at least one of the two measuring containers (1, 3) a volume-measuring device (4) for determining the volume of the material contained in the container (1, 3). <IMAGE>

BACKGROUND OF THE INVENTION From a dosing scale with a volumetric tidal gas in which it is

Dosing scales for weighing bulk materials and known e.g. from mixing devices for mixing mixtures, known dosing devices for bulk dosing of bulk materials and liquids. There are working methods for filling mixing devices in which some of the mixed components are weighed gravimetrically with the dosing scales, while the volume of the other components is measured by means of a measuring vessel.

By way of example, the mixing devices for liquids are

They are also a dry salt mixture. Here. granular additives, binders and aids are dosed by means of scales, i. gravimetric, while lightweight fillers such as polystyrene, mother-of-pearl and other similar materials must be due to their volume of fluids: they fluctuate strongly, which means not volumes.

Instead of one single measuring container they are. thus, in combination with each other two measuring vessels, the second measuring vessel arranged directly on or within the first sampling vessel is thus indirectly mounted on the weighing device. At least one of the sampling vessels can be additionally arranged for volumetric measurement, so that in addition to the gravimetric detection of the contents of these sampling vessels, the volumes of selected bulk materials or liquids can also be determined.

instead of two separate devices, which are dosed by two sampling containers, the contents of which can be determined free of charge, wherein the content in at least: ne3 to arrange both measuring cups;

arranged rotationally symmetrically, so the time in the larger / first / sampling container is smaller / second / measuring container arranged concentrically.

In this case, in the axial direction, the second metering vessel may exceed the first metering vessel. It is also expedient to provide the first metering vessel with a lid, wherein the second metering vessel can either be hinged on this lid or pass through an opening formed on the lid. If the first measuring vessel is open, the second measuring vessel in the first sampling vessel may be suspended by means of beams.

For a number of cases, but also a second proportional vessel was equipped at the bottom with a discharge device with a closable aggregate, while the discharge device of the second measuring vessel can

The volumetric metering device thus determines the state p1 of the geometric shape of the measuring vessel and automatically determines from the material level its volume of the automatic metering device. Some delivery of bulk materials in case of filling values.

At the same time, however, it is expedient to determine additionally the weight of these materials, since, in the case of extremely low weight proportions of certain substances, it is necessary. it is possible to choose a higher volume dosing. Thus, the result from the weight and oojemotic detection of bulk materials can be selected in this manner. weighing device, can select the parameter of the second measuring vessel. Then, as a dosage parameter, in the first uniform vessel, it could also be determined to determine

If the second groove is proportional, it is stored.

At the same time, when the closure aggregate of the first metering vessel is opened, the closure empties can be opened by means of both the aggregate metering vessels of the first aggregate of the second metering vessel, thereby bringing both contents to and from the mixing device.

The solution proposed herewith allows the regattas to be more or less open to the boiled first of the sealing aggregate of the inner measuring vessel. When both shut-off valves are opened at the same time, mixing is carried out in the mixer until the contents of both measuring vessels are emptied, whereas if the shut-off unit of the inner measuring vessel is first opened, mixing may already occur in the first measuring vessel. both mixed components with liquids.

According to another embodiment, the first measuring vessel may be provided with a separate discharge device. According to this method, the order in which the individual components of the two measuring vessels are removed as a mixing device is completely arbitrary and independent of anything.

In that way, both the closing means and the simultaneous detection of both the volume and the weight of the bulk material or liquid in at least one of the two collecting containers can then be carried out in a convenient manner, e.g. by calculation, determination of weight of other dosed substances. Particularly preferred is an embodiment according to the invention, in which the volumetric measuring device or the device for measuring the volume of the device is of the same type. Measurement of the state known are movable between levels using a water meter, float sensor. However, it is also possible to use another device for measuring the filling condition, consisting of optical or other physical filling, which in themselves are in two positions. In the case of determination, it can be used in a simple manner as
