Description

Известны вращающиес  печи дл  обжига материалов с устроенными на внутренних стенках нечи насадками, предназначенными дл  усилени  теплоотдачи от газов материалу. Однако интенсивность перемешивани  газов И материала в таких печах недостаточна.Rotary kilns are known for firing materials with nozzles arranged on the inner walls, designed to enhance heat transfer from gases to the material. However, the intensity of mixing of gases and material in such furnaces is insufficient.

В описываемой печи дл  повыщени  интенсивности перемешивани  газов И материала и выравнивани  толщины сло  материала при его движении по печи насадки выполнены в виде кольцевых порогов, устроенных в об.муровке печи из того же материала.In the described furnace, in order to increase the intensity of mixing of gases and material and level the thickness of the layer of material as it moves through the furnace, the nozzles are made in the form of annular thresholds arranged in the obram of the furnace of the same material.

На Чертеже изображена схема печи.The drawing shows a diagram of the furnace.

Вращающа с  печь дл  обжига материалов состоит из кожуха /, кольцевых насадок-порогов 2 н конусных откосников 3.Rotating kiln for firing materials consists of a casing /, annular nozzles, thresholds 2 n conical slopes 3.

Во врем  обжига материалов в печи пороги 2 сжимают поток газов И, преп тству  прохождению материалов, способствуют более активному перемешиванию. На поверхност х 4 порогов 2 происходит экранизаци  лучистой энергии, что усиливает теплоотдачу от газов материалу. Промежутки 5 между порогами 2 накапливают обжигаемый материал, благодар  чему происходит выравнивание ве.тичины сло  материала, при движении посл еднего вдоль печи.During firing of materials in the furnace, thresholds 2 compress the flow of gases, And, preventing the passage of materials, contribute to more active mixing. On the surfaces 4 of the thresholds 2, radiant energy is screened, which increases the heat transfer from the gases to the material. The gaps 5 between the thresholds 2 accumulate the burning material, due to which the leveling of the material layer occurs when the latter moves along the furnace.

Описываема  печь позвол ет повысить эффективность обжигл, значительно снизить пылеобразование в печи и пылеунос из нее, устранить перенос материалов, частично или полностью проклеенных, а также сухих, нагретых до высоких температур, из гор чих зон печи в более холодные, увеличить равномерность технологического процесса и отказатьс  от применени  теплообменников различных конструкций, керамических, бетонных и металлических. Стоимость теплообменников очень велика, доход  в отдельных случа х, например, дл  сводчатых пеплообменников, до 100000 руб., а долговечность и эффективносгь недостаточны.The described furnace allows to increase the efficiency of burning, significantly reduce dust generation in the furnace and dust removal from it, eliminate the transfer of materials, partially or fully glued, as well as dry, heated to high temperatures, from the hot zones of the furnace to the colder ones, increase the uniformity of the process and Refuse to use heat exchangers of various designs, ceramic, concrete and metal. The cost of heat exchangers is very high, income in some cases, for example, for vaulted ash exchangers, is up to 100,000 rubles, and durability and efficiency are insufficient.

Предмет изобретени Subject invention

Вращающа с  печь Дот  обжига материалов с устроеиным-и на внутренних . стенках печи насадками, предназначенными дл  усилени  теплоотдачи от газов материалу, отличающа с  тем, что, с целыо повыщени  интенсивности перемещивани  газов и материала и выравнивани  толщины сло  материала при его дв-ижении по печи, насад ки выиолнены в виде кольцевых, цорогов устроенных в обмуровке печ« из того же материала.Rotary kiln Dot baking materials with ustroyin-and internal. furnace walls with nozzles designed to enhance the heat transfer from gases to the material, characterized in that, in order to increase the intensity of gas and material movement and level the thickness of the material layer when it is twisted over the furnace, the nozzles are formed as circular rings, arranged in a wrapping stove "of the same material.
