Изобретение относитс к производству строительных материалов, а именно к производству искусственных пористых заполнителей - керамзита. .The invention relates to the production of building materials, namely the production of artificial porous aggregates - expanded clay. .

Известен способ производства керамзита, включающий введение эмульсионной органической добавки в про- цессе гранул ции сухого порошкообразного глинистого сырь и обжиг,. |дA known method for the production of expanded clay, including the introduction of an emulsion organic additive in the process of granulation of dry powdered clay raw material and roasting ,. | d

В качестве эмульсионной органической добавки ввод т эмульсию мазута в воде состава,ч.; 1 мазута и 6 воды 1 мазута, 1 окислов железа и 6 воды 1, Тонкоизмельченные окис- 5 лы железа,например пиритные огарки, в данном случае выполн ют роль стабилизатора приготовленной эмульсии.As an emulsion organic additive, a fuel oil emulsion is introduced into the composition water, h; 1 fuel oil and 6 water 1 fuel oil, 1 iron oxide and 6 water 1, Finely divided iron oxides, such as pyrite cinders, in this case act as a stabilizer of the prepared emulsion.

Недостатком этого способа вл етс необходимость приготовлени сус- 20 пензии стабилизатора, стабилизационные свойства которого недостаточны дл обеспечени равномерности распределени эмульсионных частиц мазута в воде. В результате полученный керам25 зит обладает достаточно высокой объеглной массой, равной 0,49 г/см®The disadvantage of this method is the need to prepare a suspension of the stabilizer, the stabilization properties of which are insufficient to ensure uniform distribution of the emulsion oil particles in water. As a result, the obtained ceram25Zit has a fairly high total mass, equal to 0.49 g / cm®

Цель изобретени - упрощение технологии изготовлени и снижение Ъбъем-; ной массы керамзита, ЗОThe purpose of the invention is to simplify the manufacturing technology and reduce the volume; Noah mass claydite, ZOR

Это достигаетс тем, что в способе производства керамзита, включающем введение эмульсионной органической добавки в процессе гранул ции сухого порсвйкообразного глинистого сырь и обжиг, ввод т эмульсионную органическую добавку, содержащую: 1 ч.мазута и 6-8 ч,стабилизаторашлама мокрой очистки, запыленного глинистыми частицами воздуха.This is achieved by the fact that in the method of production of expanded clay, which includes the introduction of an emulsion organic additive in the process of granulation of dry porcine-like clay raw material and roasting, an emulsion organic additive is introduced that contains: 1 part of black oil and 6-8 h, stabilizer of wet cleaning, dusty clay air particles.

Шлам получают при очистке отход щих газов при помоле глин ного сырь с воздушной сепарацией, а также при очистке отход щих газов от керамзитообжигательных печей.Sludge is obtained by cleaning the exhaust gases by grinding clay raw materials with air separation, as well as by cleaning the exhaust gases from expanded clay kilns.

Шлам получают с концентрацией глинистых частиц 10-20%,достаточной дл приготовлени эмульсии.The slurry is obtained with a clay concentration of 10-20%, sufficient to prepare the emulsion.

Дисперсность глинистых частиц составл ет Ь.50и по Товарову.The dispersity of the clay particles is L.50I for the goods.

Сравнительные данные о стабильности эмульсий с известным и, предлагаемым стабилизатором приведены в табл,1.Comparative data on the stability of emulsions with known and, the proposed stabilizer is given in table. 1.

Claims

The composition of the emulsions: 1 part of fuel oil, 1 part of stabilizer and 6 hours, water (by weight, with a known method, an example of the implementation of the proposed method. After grinding in the mill and sedimentation of clay in cyclones, the dusty air passes through the wet stage dust collectors. For example, rotoclones, PVM air cleaners and similar devices can be used as dust traps. A distinctive feature of these devices is the possibility of obtaining with a concentration sufficient to prepare emulsions. The emulsion is supplied to the turbulent mixer, where the heated fuel oil from the supply tank is also metered in. The prepared emulsion is supplied to the supply tank, which is sent to the screw mixer and granulator using a pump. In addition to the advantages associated with improving the stability of the emulsions according to the proposed method, the need for special preparation of clay suspensions, as provided for in the known methods: pyrite ogars and used parts of water, 1 part of black oil, 7 parts of shampoo. Zita, including the introduction of an emulsion organic additive in the process of granulation of dry powdered clay raw materials and roasting, characterized in that, in order to simplify the manufacturing technology and reduce the bulk weight of haydite, an emulsion organic additive is introduced containing 1 hour of fuel oil and 6-8 hours of stabilizer - sludge wet cleaning, dusty clay air particles.
