Description
Изобретение относитс к промышленности строительных материалов и может быть использовано в производстве керамзита .The invention relates to the building materials industry and can be used in the production of expanded clay.
Известен способ получени керамзита, включающий смачивание глинистого сырь нефтепродуктом дл повышени его вспучи- ваемости.A known method for producing expanded clay includes wetting the clay raw material with an oil product to increase its expansion.
Наиболее близким вл етс способ производства керамзита, в котором зерна дроб- леного глинистого сырь смачивают вспучивающей добавкой из раствора хлористого кальци .The closest is the method for the production of expanded clay, in which grains of crushed clay raw material are moistened with an intumescent from a solution of calcium chloride.
Цель изобретени - повышение вспучи- ваемости.The purpose of the invention is to increase the expansion.
Способ осуществл ют следующим образом .The method is carried out as follows.
Пример 1. Камневидное глинистое сырье (сланцы, аргиллиты и т.п.) дроб т до размера зерен не более 20 мм и направл ют в термоподготовитель (сушильный барабан, слоевой подготовитель и др.) и нагревают до температуры 300-400°С. После 15-20-минутной выдержки при температуре подготовки зернистый материал в гор чем состо нии обрабатывают в смесителе принудительного действи , например в двухвальном смесителе закрытого типа (глиномешалка), подава в агрегат жидкий нефтепродукт из расчета 1,2...1,5% мае. от веса глинистого сырь . Неусвоившиес пары нефтепродукта отсасываютс вентил тором и подаютс на дожигание либо в термоподготовитель, либо в обжиговый агрегат . Полученный полуфабрикат направл ют на обжига керамзита,Example 1. Stone-like clay raw materials (shales, mudstones, etc.) were crushed to a grain size of no more than 20 mm and sent to a thermal preparation (dryer, layered preparation, etc.) and heated to a temperature of 300-400 ° C. After a period of 15–20 minutes at the preparation temperature, the granular material in the hot state is treated in a forced-action mixer, for example, in a closed-type two-shaft mixer (clay mixer), feeding liquid petroleum product at the rate of 1.2 ... 1.5% May from the weight of clay raw materials. Unassimilated oil product vapors are sucked off by the fan and fed to the afterburner either to the thermal preparation unit or to the roasting unit. The obtained semi-finished product is directed to the firing of expanded clay,
Пример 2. Камневидное глинистое сырье после дроблени до крупности зерен не более 20 мм направл ют в термоподготовитель и нагревают до температуры в интервале 300-400°С. После 15-20-минутной выдержки гор чий материал обрабатывают в закрытом смесителе, в который подают одновременно раствор гидрата хлорида железа 30...33%-ной концентрации из расчета 1,0...3,0 мае. % РеСЬ бНаОExample 2. After crushing to a grain size of grains not exceeding 20 mm, stone-like clay raw materials are sent to a thermal preparation unit and heated to a temperature in the range of 300-400 ° C. After 15–20 minutes of exposure, the hot material is processed in a closed mixer, to which a solution of iron chloride hydrate of 30–33% concentration at the rate of 1.0–3.0 May is simultaneously supplied. % DIFE bNAO

и жидкий нефтепродукт, например мазут из расчета 0,8..,1,5% мае. от массы глинистого материала, Подготовленный таким образом полуфабрикат направл ют на обжиг керамзита. Неусвоившиес пары железосодержащей соли и нефтепродукта направл ют на утилизацию. Результаты испытаний сведены в таблицу.and liquid petroleum products, such as fuel oil at the rate of 0.8 .., 1.5% May. from the mass of clay material, the semi-finished product prepared in this way is directed to the firing of expanded clay. Un-assimilated vapors of iron-containing salt and oil product are sent for recycling. The test results are summarized in table.
Получаемый керамзит имеет насыпную плотность 170-220 кг/м3.The resulting claydite has a bulk density of 170-220 kg / m3.
