Double-rotary-cylinder drying machine for bentonite

Abstract

The invention aims to provide a double-rotary-cylinder drying machine for bentonite, comprising two horizontal drying cylinders. A hollow rotating shaft in which heated air can be charged and which is covered with stirring discs is disposed in the center of each drying cylinder. Stirring sheets in the drying cylinders are used for stirring powder. The left side of each rotating shaft admits incoming air, and the incoming air is generated by a blower and is heated by an air heater before being charged into the rotating shafts; the right side of each rotating shaft is provided with an outflow pipe; the upper right of each drying cylinder is provided with a feed hole; the lower left of each drying cylinder is provided with a discharge hole. The two drying cylinders are provided, the heated air is charged into the drying cylinders for indirect drying, the two drying cylinders are connected together through a transfer pipe, only the stirring sheets and the stirring discs are disposed in each drying cylinder, and drying is more sufficient. The whole double-rotary-cylinder drying machine for bentonite is better in drying effect, drying can be performed selectively as required, production efficiency is improved, and the double-rotary-cylinder drying machine for bentonite is applicable to production.

Description

technical field [0001] The invention relates to the field of bentonite drying, in particular to a double-rotating cylinder drying device for bentonite. Background technique [0002] Bentonite is relatively humid after mining, and it needs to be dried and dried before it is pulverized or after it is sodiumized. At present, most of them are dried in a drying kiln. The temperature of the drying kiln is relatively high, which is suitable for Wet and sticky bentonite just mined is dried directly. The drying effect is not uniform and most of the bentonite cannot be dried. If the temperature is too high, the bentonite will be damaged. Therefore, it is very necessary to solve this problem. Contents of the invention [0003] The invention provides a double rotary cylinder drying device for bentonite, which adopts two rotary cylinders for drying by feeding heated air, and the two rotary cylinders can be fed and dried at the same time, or one rotary cylinder can be advanced in parall...

Problems solved by technology

[0002] Bentonite is relatively humid after mining, and it needs to be dried and dried before it is pulverized or after it is sodiumized. At present, most of them are dried in a drying kiln. The temperature of the drying kiln is relatively high, which is suitable for The wet and sticky bentonite just mined is dried directly. The drying effect is uneven and most of the bentonite cannot be dried. If the temperature is too high, the bentonite will be damaged. Therefore, it is very necessary to solve this problem.
