Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
As shown in Figure 1, for this utility model one sludge drying device helix transporting device, it includes cylinder 10, screw rod 20, heat exchanger (not shown) and motor 30, wherein, cylinder 10 is hollow structure, and one end of cylinder 10 is provided above feed hopper 12, the other end is arranged below discharge bucket 13；It is internal that screw rod 20 is arranged on cylinder 10, screw rod 20 includes the body of rod 21 and is arranged at the extruding plate 22 that the body of rod 21 surface extends in the shape of a spiral, heat transferring medium input channel 211 and heat transferring medium output channel 212 that the body of rod 21 length direction of postponing extends it is provided with in the body of rod 21, heat transferring medium input channel 211 and heat transferring medium output channel 212 turn in the front end of the body of rod 21, heat transferring medium input channel 211 and heat transferring medium output channel 212 extend to the rear end of the body of rod 21, and form a heat transferring medium import and heat transferring medium outlet respectively；Being provided with heat exchanger fin and heat exchanger fin in heat exchanger and carry out the heat exchanger tube of heat exchange, the outfan of heat exchanger tube is exported in heat transferring medium by pipeline connection in heat transferring medium import, input by pipeline connection；The body of motor 30 is fixed on cylinder 10, and the rotating shaft of this motor 30 couples with screw rod 20, in order to drive screw rod 20 to rotate.
This utility model is operationally, motor 30 drives screw rod 20 in cylinder 10 inner rotation, mud is added to cylinder 10 from feed hopper 12, rotation along with screw rod 20, mud is extruded and is delivered to discharge bucket 13 place, in mud course of conveying, the heat transferring medium that in heat exchanger, output temperature is higher, this heat transferring medium enters in heat transferring medium input channel 211 and heat transferring medium output channel 212, in the body of rod 21, the mud that in heat transferring medium and cylinder 10, temperature is relatively low carries out heat exchange, improve the temperature of mud, the final mud from discharge bucket 13 output is preheated, heat transferring medium is then back in heat exchanger heat exchange again and follow-up mud is preheated.Compared to existing helix transporting device, this utility model owing to arranging heat exchanger channels in screw rod 20, while extruding conveying mud, it is possible to promoting the temperature of mud, mud being preheated, thus improve the efficiency of sludge drying.
