Изобретение относитс  к оборудованию дл  термической обработки, например, обжига, сыпучих тонкомолотых материалов в восход щем потоке нагретого газа с те.мпературой 1000°С и более и может быть использовано на машиностроительных заводах, в цехах точного лить  по выплавл емым модел м - дл  прокатки маршалита и в промышленности строительных и теплоизол ционных материалов-в производстве вспученного нерлита, пудры и т. д.The invention relates to equipment for heat treatment, for example, firing, bulk fine materials in an upward flow of heated gas with a temperature of 1000 ° C and more, and can be used in machine-building plants, in shops of precise casting on melted models for rolling Marshalite and in the industry of building and thermal insulation materials — in the production of expanded nerlyta, powder, etc.

Известна печь дл  обжига перлитового порошка и пудры, содержаща  вертикальную футерованную шахту с нижней подачей теплоносител  и материала и воздухонодвод щим патрубком в отвод щем газоходе дл  разбавлени  газов перед подачей в осадительные устройства, установленные за печью.A known kiln for the burning of perlite powder and powder, containing a vertical lined shaft with a lower supply of heat carrier and material and an air inlet duct in a flue gas duct for diluting gases before it is fed into the precipitation devices installed behind the furnace.

Подача малого количества воздуха вызывает т желые температурные услови  работы осадительных устройств, которые не позвол ют применить рукавные фильтры дл  тонкой очистки дымовых газов от взнеси обрабатываемого материала, а подача необходимого количества воздуха непосредственпо в газоход приводит к задуванию печи, нарушению ее аэродинамического режима.The supply of a small amount of air causes severe temperature conditions for the operation of the precipitation devices, which do not allow the use of bag filters for fine cleaning of flue gases from depositing the material being processed, and supplying the required amount of air directly into the gas duct leads to the blowing of the furnace and its aerodynamic regime.

Цель изобретени  - стабилизаци  аэродинамического режима печи.The purpose of the invention is to stabilize the aerodynamic regime of the furnace.

Достигаетс  это тем, что над шахтой соосно с ней установлена конусна  камера с конической полой вставкой внутри, а воздухоподвод щий патрубок расположен тапгенциально в конусной камере ниже верхнего уровн  конической пстав н.This is achieved by the fact that a conical chamber with a conical hollow insert inside is installed coaxially with the shaft above the shaft, and the air supply pipe is located tangentially in the conical chamber below the upper level of the conical rod.

Сушиость изобретени  по сн етс  чертежом .,..j Печь состоит из металлического кожуха The dryness of the invention is illustrated in the drawing., .. j The furnace consists of a metal casing

с футеровкой 2 шахты 3, закрепленного на основании 4. Последнее закреплено на илощадке 5 и  вл етс  верхней частью топки 6, котора  подвешена к шахте 3. Па кожухе 1 в верхней части установлена конусна  камера-смеситель с конической насадкой 8 дл  выхода потока гор чих газов с твердой взвесью и патрубком 9 тангенциального ввода холодного воздуха, который установлен ниже верхнего уровн  конической насадки 8. Сверху на конусном с.месителе 7 закреплен съемный коленчатый патрубок 10, который соедин етс  с системой осадительиых устройств (на чертеже не показаны). В нижней части печи установлена течка 11 дл  нодачи обрабатываемого материала в печь. В топке 6 установлены горелка 12 и сопло 13 дл  подачи вторичного воздуха.with lining 2 of the shaft 3 fixed on the base 4. The latter is fixed on the platform 5 and is the upper part of the furnace 6, which is suspended from the shaft 3. In the upper part of the casing 1 there is a conical mixing chamber with a conical nozzle 8 to exit gases with a solid suspension and nozzle 9 of the tangential entry of cold air, which is installed below the upper level of the conical nozzle 8. On top of the conical mixer 7 there is a detachable elbow nozzle 10, which is connected to a system of settling devices (shown in not shown). In the lower part of the furnace, the chute 11 is installed to add the processed material to the furnace. Burner 12 and nozzle 13 for supplying secondary air are installed in the furnace 6.

Печь работает следующим образом.The furnace works as follows.

Поток раскаленпых газов из топки 6 устремл етс  в шахту 3 и подхватывает матерпA stream of red-hot gases from the furnace 6 rushes into shaft 3 and picks up materp
