A method and an apparatus for feeding preheaters having heating elements for the feedstock of glass melting installations. In order to distribute the feedstock in an extremely thin, but uniform layer thickness on and between the upper heating elements, thereby effectively suppressing or avoiding agglutination of particles and accumulation of the feedstock, a distributor device is arranged above the topmost heating elements including at least three pivotable distributor plates, the pivoting axes of which run in the horizontal edges of a virtual prism. The topmost distributor plate throws the feedstock alternately onto one of the distributor plates arranged underneath, which throws the caught feedstock to one of its sides sternwards. The movements of the distributor plates are controlled by sensors with an evaluation and control circuit and actuators assigned to the distributor plates with the aim of a uniform area distribution of the feedstock over the cross section of the preheater.

1. A method for feeding preheaters having heating elements for the feed material of glass melting installations, the feed material being applied in a uniform distribution onto the uppermost heating elements, in a manner controlled by sensors, comprising the steps: a) arranging a distributor device including at least three pivotable distributor plates, with an uppermost distributor plate arranged above two lower distributor plates, pivot axes of each of the distributor plates running in horizontal edges of a virtual prism, above the uppermost heating elements,b) throwing the feed material by the uppermost distributor plate in alternating fashion onto one of the lower distributor plates situated thereunder, by selected rotational movement of the upper distributor plate, the receiving lower distributor plate then in turn throwing the received feed material downwardly toward one of its sides by selected rotational movement of the lower distributor plate, and(c) controlling the movements of the distributor plates by sensors having an evaluation and control circuit, the evaluation and control circuit controlling actuating elements assigned to the distributor plates, so as to achieve a uniform surface distribution of the feed material over a cross-section of the preheater. 2. A device for feeding preheaters having a distributor device and having heating elements for the feed material of glass melting installations, the feed material being capable of being applied onto the uppermost heating elements in a uniform distribution, in a manner controlled by sensors, comprising: a) a distributor device situated above the uppermost heating elements having at least three pivotable distributor plates whose pivot axes run in the horizontal edges of a virtual prism, including an uppermost distributor plate and two lower distributor plates,b) the uppermost distributor plate being pivotable in alternating fashion between two end positions in which the feed material can be thrown onto one of the distributor plates situated thereunder, by which the received feed material can be thrown downwardly toward one of its sides, and(c) sensors arranged to sense the feed material and provide signals to an evaluation and control circuit with actuating elements controlled by the evaluation and control circuit which are arranged to pivot the distributor plates in order to achieve a uniform surface distribution of the feed material over the cross-section of the preheater. 3. The device as recited in claim 2, wherein the axis of the uppermost distributor plate is situated in the vertical midplane of the distributor device, and thereunder are situated two further axes of the lower distributor plates disposed in a mirror-symmetrical configuration on both sides of the vertical midplane of the distributor device. 4. The device as recited in claim 3, wherein a glide path of the two lower distributor plates is limited in each case by a deflecting plate situated in a peripheral edge area of the distributor device. 5. The device as recited in claim 2, wherein the sensors are situated in a horizontal matrix configuration that is situated in a horizontal plane at an upper end of the preheater. 6. The device as recited in claim 2, wherein the sensors extend into intermediate spaces between the uppermost heating elements. 7. The device as recited in claim 2, wherein the distributor device has, in a mirror-symmetrical configuration, two angled roof surfaces whose virtual prolongations intersect in a midplane of the distributor device. 8. A method for feeding preheaters having heating elements for the feed material of glass melting installations, comprising the steps: a) supplying a feed material from above onto an uppermost pivotable distributor plate having a horizontal pivoting axis,b) selectively rotating the uppermost distributor plate about the horizontal pivoting axis to cause the feed material to slide on the uppermost pivotable distributor plate downwardly alternately onto one of at least two lower pivotable distributor plates, each having a horizontal pivoting axis,c) selectively rotating the lower pivotable distributor plates about their horizontal pivoting axes to cause the feed material to slide on the lower pivotable distributor plates downwardly toward the preheater, andd) controlling the pivotal movements of the distributor plates by sensors arranged to sense the feed material and having an evaluation and control circuit, the evaluation and control circuit controlling actuating elements assigned to the distributor plates and arranged to selectively pivot the distributor plates, so as to achieve a uniform surface distribution of the feed material over a cross-section of the preheater.
