Allocation device for solids

Building material "mixing plants

The invention relates to a device for distributing pent materials in building material mixing systems and, in particular, to a device for variable, automatic Allocate clay to its pesticide material components in dosing and mixing systems for the preparation of a sand-lime brick or concrete stone Rohnasee, b * i for each material component a scale, an intermediate container and a sub-mixer leading conveyor is present.

In dosing and mixing positions «the single material components are grounded according to weight Best immt by volume and subjected to an intensive mixing process. The more intensively the mixture is made, the less it is it is wise to work with a security guardian one of its material components, e.g. lime or cement, drive su.

With the well-known Cisargesunists, they become one Material components are suggested one after the other. The coward

is "in" a longer period of time, B "in the well-known Durohlaufmiaehern the material addition is regulated by hand causes.

When two, three or more building block presses are working

and the presses are to produce bricks of different quality, a different composition of the mixture components is required. Here, the requirement that the one a Materialkoaponenten also be made at different percentages, side absolutely equal to the _mixer's known you * Zufe # i devices! Sufriedenstellend not work. If the operating staff does not pay attention to a change in the composition of the material components, one or the other material component runs through the continuous mixer without mixing with other material components, which inevitably leads to rejects in the end product.

It is therefore the object of the invention to improve the metering and mixing systems so that with the batch mixers a course mixed side and with the continuous mixers an even addition of all Material components is guaranteed «

The object is solved by erfindungsgemäft, daft a control for each scale with a control element for the conveyor drive of the scale sugeordneten conveyor meohaniseh coupled and UMw SveüePbereieh beiöejr Steuereleisen "· yerhSlsnisgleieh via an adjusting element is adjustable.

Potentiometers as control elements have proven to be technically the cheapest and most economical. However, other control elements, see B * variable transformers, can also be selected which have the same ratio Allow control of the scale and conveyor drive of the discharge.

An Ausafübrungsbeispiel the subject of the invention is shown in the drawing sohematlsoh and is in the following are described in more detail.

Above conveyors (not shown) are one of its millunga components, e.g., sand in one Livestock container 1 and lime in a weighing container 2, introduced. Nash reaching the adjustable target weight the weighed amounts of the individual milling components fall automatically in a manner known per se in intermediate container 3 and H.

If it is assumed that the lime component in weighing container 2 lamer has the same QrOb * , then with a variation in the weight proportion of the sand mix, the conveying speed of the conveyor 5 for the sand component from the intermediate container 3 must be changed proportionally. If the weight »^ t-ecause the Misehungskomponente Sand s. B. to 2 ^r% increases, so does the conveyor 5 has to run faster for the mixture component Sand 25% to the same Auslaufseit" wipe the components of the mixture of sand and lime reach su . For this purpose, a control element 10 for the weighing container 1 of the mixing component sand is mechanically coupled to a control element 11 for driving the conveying device 5. In order to be able to pass through a proportional change in the weight fraction of sand and the drive speed of the conveyor 5 by means of the two mechanically coupled control elements 10 and 11, an adjusting knob 12 is provided that clicks on the
