Описание вариантов осуществления: Description of embodiments:
Размеры пластины с отверстием в боковых частях могут быть больше размеров отверстия не менее чем на величину расстояния между ребрами барабана, что позволит устранить паразитный переток воздуха между коллектором и окружающим пространством через примыкающие к краям пластины, частично расположенные напротив отверстия, сектора барабана. Сектор барабана ограничен соседними радиальными ребрами, внешним и внутренним барабанами. The dimensions of the plate with the hole in the lateral parts can be larger than the size of the hole by no less than the distance between the ribs of the drum, which will eliminate spurious air flow between the collector and the surrounding space through the adjacent plate edges, partially located opposite the hole, of the drum sector. The drum sector is bounded by adjacent radial ribs, outer and inner drums.
Размеры пластины с отверстием в радиальном направлении могут быть больше размеров расстояния между концентрическими цилиндрами, что обеспечит герметичность между пластиной с отверстием и цилиндрами барабана, ограничивающим сектора. The dimensions of the plate with the hole in the radial direction can be larger than the size of the distance between the concentric cylinders, which will ensure tightness between the plate with the hole and the drum cylinders that bound the sectors.
Прижим к барабану может состоять из прижимной пластины с одной стороны которой расположен прижимной палец, второй конец прижимной пластины жестко закреплен на вертикальной стенке корпуса. Конец прижимной пластины, ближний к пальцу при этом может быть подпружинен - закреплен на винте с пружиной между головкой винта и пластиной. Конструкция прижима достаточно проста и позволяет регулировать силу прижима пластины к торцевой части барабана.
Краткое описание чертежей: The clamp to the drum may consist of a pressure plate on one side of which a pressure finger is located, the second end of the pressure plate is rigidly fixed to the vertical wall of the housing. The end of the pressure plate closest to the finger can be spring loaded - mounted on a screw with a spring between the screw head and the plate. The design of the clip is quite simple and allows you to adjust the force of the clamp plate to the end of the drum. Brief Description of the Drawings:

Устройство действует следующим образом: в корпусе 1 установлен вращающийся колосник, содержащий внешний цилиндр 2 и внутренний цилиндр 3, между цилиндрами расположены радиальные ребра 4. К торцевой стенке вращающегося колосника, между внутренним и внешним цилиндрами примыкает пластина с отверстием 5, герметично по краям соединенная с коллектором 7, который, в свою очередь герметично соединен с подающей воздух трубой 6. Форма пластины с отверстием соответствует с перекрытием кольцевой площадке входных секторов барабана, ограниченных внешним и внутренним цилиндром барабанов и вертикальными стенками рабочих каналов, на внешней поверхности сегментах которых расположено горящее топливо и в целом выгнута вдоль сегмента кольца. Коллектор прижимается
прижимной пластиной 8 с пальцем прижимной пластины 9. Прижимная пластина жестко соединена с вертикальными стенками корпуса концом прижимной пластины 10, а конец 11 подпружинен как за счет пружинящих свойств пластины, так и за счет подпружиненного конца - винта с пружиной.

The device operates as follows: a rotary grate is installed in the housing 1, comprising an outer cylinder 2 and an inner cylinder 3, radial ribs 4 are located between the cylinders. A plate with an opening 5 adjacent to the end wall of the rotary grate, between the inner and outer cylinders, is tightly connected to the edges with a collector 7, which, in turn, is hermetically connected to the air supply pipe 6. The shape of the plate with the hole corresponds to overlapping the annular area of the input sectors of the drum, limited externally m and inner cylinder drums and the vertical walls of the working channels on the outer surface of the segments which is arranged burning fuel and generally curved along a ring segment. Collector is pressed the pressure plate 8 with the finger of the pressure plate 9. The pressure plate is rigidly connected to the vertical walls of the housing by the end of the pressure plate 10, and the end 11 is spring-loaded due to the spring properties of the plate, and due to the spring-loaded end - a screw with a spring. The finger presses the air supply device into the rotating grate and, accordingly, the plate with the hole to the drum, which increases the reliability and efficiency of the air supply device.
Технический результат - повышение равномерности подачи воздуха достигается за счет наличия коллектора подачи воздуха, равномерно распределяющего поток воздуха между отверстием в пластине и подающей воздух трубой. EFFECT: increased uniformity of air supply is achieved due to the presence of an air supply manifold that evenly distributes the air flow between the hole in the plate and the air supply pipe.
