In carbon black manufacture field, often need drying machine to heat carbon black, but existing carbon black drying equipment, one bend pipe is often set in cylinder rear end to be connected with fire-box body, then high-temperature gas just enters cylinder inside by bend pipe carbon black is carried out to heat drying, then high-temperature gas is taken away by air exhauster again, but due to excess Temperature in high-temperature gas and contain impurity, in high-temperature gas flows process can with carbon black in element generation chemical reaction, affect the processing quality of carbon black, and flow in process at high-temperature gas, also can take away fine particle, reduced the production output of carbon black, also can increase the filtration load of follow-up filter, indirectly improved production cost.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of dry materials quality, cost is low and drying efficiency is high novel indirect heating type rotary dryer of improving is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel indirect heating type rotary dryer, it comprises cylinder, the rotating transmission device of head roll, described cylinder two ends are respectively equipped with charging aperture and discharging opening, described cylinder feed end is also connected with an air draft pipe, on described outer surface of cylinder, be arranged with a fire-box body, in cylinder, be provided with many mozzles, one end of mozzle is positioned at air draft pipe, and the mozzle other end is positioned at the discharge end of cylinder and is connected with fire-box body by bend pipe.
Described cylinder two ends are respectively arranged with sealing device, and the discharge end of cylinder is also provided with a bonnet.
Described cylinder feed end below is provided with a catch wheel device.
Described cylinder discharge end below is provided with a riding wheel apparatus.
On described inner wall of rotary drum, interval is evenly provided with a plurality of copy plates.
The gradient of described cylinder is 1:120.
Between many described mozzles, be provided with connecting plate, make it form triangular groove.
The utlity model has following advantage: drying machine of the present utility model, material does not directly directly contact with hot-air with flue gas, but by fire-box body and mozzle, it is carried out to heat drying, has guaranteed the quality of dry materials; By copy plate, the material of taking up is fallen in triangular groove, the heat spreading out of by mozzle is dried material, has increased heat transfer area, has improved dry materials efficiency; In dry materials process, be difficult for being taken away fine particle by air, reduced the loss of material, reduced the load of follow-up filter, make the cost of dry materials.
