DE1066151B - Method and device for the preparation of mixtures of different weights - Google Patents

Description

GERMAN

The invention relates to the preparation of mixtures of goods of different weights by the Separating the mixture from jigs of any type using a separating medium such as water or the like. The main patent application M 21990 VI / la proposes such typesetting machines in which a calm, d. H. a discharge of the heavy products not impaired by the pulse movement of the separating liquid is achieved while eliminating the previous bridges that interfere with the stratification. It such discharge conveyors are used that, by floats depending on the entered Controlled stratification, allow a constant filling of the discharge shafts by the material to be discharged. These shafts, which are always filled, shield the discharge openings due to their sealing column against the pulse movement of the separating liquid, whereby a calm discharge of the heavy products is guaranteed.

The invention provides for a further simplification of the devices for carrying out the method the main patent application M 21990 VI / la. Its essence is seen in the fact that between Set sieve and conveyor slides, cellular wheels, flaps or the like are installed, which the constant, approximately vertical, Hold the constantly sealing column of goods in an intermediate layer that is sufficient for sealing.

The invention is based on the knowledge based on practical experience that it is not it is necessary to provide a special discharge shaft from the conveyor to the setting screen and this to fill completely in order to seal it off from the bed so that the pulse movements of the separating liquid remain ineffective in the area of the discharge openings. Rather, it is sufficient to only use the discharge shafts to be constantly filled in the upper part with the sealing discharge material or the discharge shaft itself to limit this length. Taking this phenomenon into account, it has proven to be useful between the setting sieve and the conveyor controlled slides, cellular wheels, flaps or the like to be installed in such a way, that the shaft parts above these discharge organs are constantly in with the goods to be discharged a sealing height are filled, and the shaft itself can be limited to this length.

The subject of the invention is shown in the drawing in a special exemplary embodiment for three-product separation shown schematically, namely shows

For example, a double bucket elevator i _v i _{2 is} provided. According to the number of the conveying compartments J ₁ and i ₂ are located in front of the Austragsschächten P ₁ and P _2, the discharge slots W ₁ and m ₂ with the sliders M ₁ and H _2, which are superimposed at the discharge end of the settling chamber. The discharge chutes P ₁ and p ₉ to the conveyors i _v i _{2 are} separated from the setting barrel d , which is subdivided into the compartments d _v d _{2 , d 3} according to the sections b _v b _£ , b _{s of} the setting screen b. In addition, in the discharge chutes P ₁ and p ₂ to the bucket elevators I ₁ and i _{2 there are} cell wheels O ₁ and O ₂ , the circulation of which is regulated by the floats k ₁ and k _{2 located within the jig chamber.} While the float ^ ₁ responds to the material to be separated with the highest specific weight, the swimmer It ₂ reacts to the material to be separated with average weights, the medium material. Correspondingly, the float k _{t is} connected to the drive q _{1 of} the cellular wheel O _{1 in} such a way that it regulates the discharge of the heaviest material to be separated, depending on the floating position. The same applies to the connection between the drive o / _{2 of} the cell wheel 0. ·, through a float k ₂ , which thus regulates the discharge quantity of medium. In this way, the goods to be separated, sorted by weight, leave the setting chamber through the discharge slots arranged one above the other and are discharged to the conveyors I ₁ and i _{z by the speed-controlled cell wheels O 1} and O ₂ . In this case, the impulses for the cell wheels or the like regulating the discharge amount take place through the different layers which are superposed on one another.

The individual parts by weight fall from the cellular wheels O ₁ and O ₂ through the waste chutes P ₁ and p ₂ onto the bucket elevators I ₁ and i ₂ . In this way it is achieved that conveyors such as bucket elevators or the like can also be used, to which the material must fall freely and which as such do not allow a seal against the bed. The shafts are sealed by the amount of material left in the discharge shaft P ₁ or p ₂ between the cellular wheel O ₁ or O ₂ and the discharge slot _{W 1} or W _2.
