Abstract

The utility model relates to a double heating revolving drum drier suitable for construction material and chemical industry, which belongs to material drying equipment. The utility model comprises a revolving drum, a drying furnace and a drive device for the rotation of the revolving drum, wherein, both ends of the revolving drum are respectively connected with a hot wind pipe and an exhaust fan and are provided with a feed hopper and a discharge hopper; the revolving drum passes through the drying furnace; a smoke gas outlet positioned at the upper end of the drying furnace is communicated with the hot wind pipe. By heating the inner side and the outer side of the revolving drum in a bidirectional way, the utility model can fully utilize heat energy, lowers energy consumption and effectively enhances the heat efficiency of the drying furnace; the drier has the properties of fast temperature elevation and high drying temperature and efficiency.

Description

The dual-heating type rotary drum drying machine
The utility model relates to a kind of dual-heating type rotary drum drying machine of using in building materials and the chemical engineering industry of being suitable for, and belongs to a kind of drying materials equipment.
At present, in the processing of building materials and chemical industry, especially in cement processing, extensively use rotary drum drying machine that the material of required processing is dried preliminary treatment.Rotary drum drying machine is made of the rotating cylinder of turnover material, the drying oven that is arranged at the rotating cylinder feed end, pump drainage flue gas part and rotating cylinder rotating driving device, rotating cylinder plays row and advances material operation and lifting stirring, in flowing through rotating cylinder, the thermal current of drying oven generation carries out heat exchange with material, the moisture that contains in the gasification materiel is finished the process of drying materials.Because the oven dry of this dryer material mainly is by thermal current the heating of material to be carried out, and therefore exists the energy consumption height, the material temperature rise is slow, the not high enough and low problem of drying efficiency of the thermal efficiency.
Task of the present utility model is to avoid the weak point of above-mentioned existence and a kind of dual-heating type rotary drum drying machine is provided, and to improve the thermal efficiency and the drying efficiency of rotary drum drying machine, cuts down the consumption of energy.
Task of the present utility model is finished by following scheme: it includes rotating cylinder 2, drying oven 8 and rotating cylinder rotating driving device, the two ends of rotating cylinder join with warm-air pipe 7 and exhaust column 1 respectively, and be provided with feed hopper 9 and discharge bucket 10, its difference is that rotating cylinder 2 passes drying oven 8, and the exhanst gas outlet of drying oven upper end is connected with warm-air pipe 7.
Press such scheme, primary structure characteristics of the present utility model are on the basis that keeps former drying oven with hot flue gas stream material to be dried, rotating cylinder integral body is passed drying oven 8, the rotating cylinder cylindrical shell is directly heated, like this, by to the two-way heating inside and outside the rotating cylinder, the material in the cylindrical shell is heated up rapidly, moisture content in the material is evaporated the vaporization back and is pulled away together in company with hot flue gas, thereby finish the oven dry of material is handled.The utility model makes full use of heat energy, has quick heating, the characteristics that bake out temperature is high, thereby make the thermal efficiency of dryer and drying efficiency obtain improving by a relatively large margin.
Fig. 1 is the structure chart of an embodiment of the utility model.
Fig. 2 cuts open figure for the A-A among Fig. 1.
An embodiment of the present utility model such as Fig. 1, shown in 2, has a horizontal microscler rotating cylinder 2, the both sides of rotating cylinder are equipped with big roller circle 3, the big roller circle is placed on a pair of supporting support roller 4, supporting support roller 4 links by a sprocket wheel chain 5 and a speed-changing driving device 6, drive the rotating cylinder rotation by supporting support roller 4, constitute the rotating cylinder rotating driving device, the interlude of rotating cylinder 2 passes the burner hearth of drying oven 8, be provided with labyrinth-type excluder in the burner hearth both sides, the exhanst gas outlet and the warm-air pipe 7 of drying oven 8 upper ends join, the other end of warm-air pipe then joins with the charging aperture of rotating cylinder 2 one ends, and the charging aperture place is provided with feed hopper 9, is provided with discharge bucket 10 at the other end of rotating cylinder 2, the top of discharge bucket is equipped with exhaust column 1 and joins with air exhauster, constitutes hot flue gas with warm-air pipe 7 and flows back to the road.
