Description
Йзобретение относитс к способам предотвращени смерзани и примерзани увлажненных сыпучих материалов и может быть использовано в горнорудной и металлургической промьшлен- ност х.The invention relates to methods for preventing the freezing and freezing of wetted bulk materials and can be used in the mining and metallurgical industries.
Цель изобретени - уменьшение про ности примерзани увлажненных сыпу чих материалов к металлическим поверхност м .The purpose of the invention is to reduce the frequency of the freezing of wet materials in bulk to metallic surfaces.
,П р и м е р. Бак емкостью 10 м запапн ют на. 2/3 объема водой и .засыпают 3 т остатка выпаривани шахтных вод. Содержимое перемешивают и полученный 30%-ный раствор пере- качивают в специальную емкость, откуда подают грунтовым насосом типа Гр на распылители, расположенные по обеим сторонам транспортирующих средств 5 например вагонов., PRI me R. A tank with a capacity of 10 m is stored on. 2/3 of the volume with water and 3 tons of residual evaporation of mine water are filled up. The contents are mixed and the resulting 30% solution is pumped into a special container, from where they are fed with a Gr type dirt pump to the sprayers located on both sides of the transport means 5, for example, cars.
При температуре расход 30%- ного. раствора антифризно.го вещества составл ет 1э4 кг .на 1т,At a temperature of 30% consumption. the antifreeze solution of the substance is 1-4 kg per 1 ton,
Сравнительные данные по прочности примерзани железнорудного концентрата с влажностью 8-9% и крупностью 0,05 мм к металлической по- верхностиэ обработанного по известному (СаС) и предлагаемому спо- собам приведены в таблицеComparative data on the strength of freezing of iron ore concentrate with a moisture content of 8–9% and a particle size of 0.05 mm to the metal surface processed by the known (CaC) and the proposed methods are given in the table.
Из приведенных данных следует,From the above data it follows
что прочность примерзани концентрата , обработанного 20-35%-ным раствором остатка упаривани шахтных водз уменьшаетс по сравнению с известньthat the strength of the freezing of the concentrate treated with a 20-35% solution of the residue of the evaporation of the mine waters decreases as compared with limestone

способом в 5 раз. При концентрации раствора 20% и 35% дальнейшее уменьшение прочности не достигаетс ,way 5 times. At a solution concentration of 20% and 35%, a further decrease in strength is not achieved,
5 Химический состав продукта упаривани шахтных или сточных вод горнорудных предпри тий указан. Он представл ет собой кристаллическое вещество5 The chemical composition of the product of evaporation of mine or waste waters of mining enterprises is indicated. It is a crystalline substance.
Коррозионна активность продукта упаривани вод горнорудных предпри тий почти в три раза ниже чем коррозионна активность хлористого кальци . Так 5 напримерS коррЪзионна активность (потер веса образца ста- ли-Зэ наход щегос в 30%-н,ом растворе антифриза) дл предлагаемого продукта составл ет 315 мг/м в то врем j как дл раствора хлористого кальци - 1050 . The corrosion activity of the product of the evaporation of the waters of mining enterprises is almost three times lower than the corrosive activity of calcium chloride. So, for example, 5 S is the corrosive activity (the weight loss of a sample of steel — which is in a 30% solution of antifreeze) for the proposed product is 315 mg / m, while j is 1050 for calcium chloride solution.

Продукт упаривани шахтных или сточных вод горнорудного производства ввод т в количестве 0, кг/т (по сухому веществу)The product of evaporation of mine or wastewater of mining production is introduced in the amount of 0, kg / t (dry matter basis)
Из приведенных данных видноs что по своим антифризным свойствам и коррозионной активности продукт упаривани шахтных 1VIK сточных вод горнорудного производства значительно превосходит раствор хлористого кальци и может быть успешно применен дл снижени примерзани сыпучих материалов к .транспортньм средствам в услови х низких температурFrom the above data it can be seen that in its antifreeze properties and corrosivity the product of evaporation of mine IVIK wastewater from mining production significantly exceeds calcium chloride solution and can be successfully applied to reduce freezing of bulk materials to low-temperature vehicles.
