Sludge dryer

Product introduction

With the enhancement of national economic strength improve national awareness of environmental protection city sewage treatment industry has developed rapidly the city sludge production grow with each passing day disposal and the development and utilization of sewage sludge is becoming the focus. The mud drying system of Shanghai Tongli heavy machine suitable for all kinds of sludge in high viscosity can be dry wet sludge about 85% of the drying water become less 10% water. Dry sludge drying system with negative pressure operation enhanced heat transfer device of direct heat transfer drying moisture control convenient flexible operation has a larger range of allowed product flow. In high temperature mechanical equipment simple and reliable simple structure easy cleaning fault low rate continuous operation low maintenance cost wide scope of application.

Structure principle

Sludge drying machine can be a one-time 90% moisture content of drying materials to finished products. According to the characteristics of easy agglomeration sludge drying process change the structure of the general single channel plate dryer using a combined self cleaning device greatly expanded the scope of application of single channel drying machine not only can dry all kinds of sludge. You can also dry various materials with high viscosity.

The sludge from the feeder through the chute into the dryer guide plate with the rotation of the cylinder the sludge is guided to the inclined lifting board is elevated to the center of the cylinder gradually on the formation of the material screen the high temperature gas flow through the sludge preheating and evaporation of the water. When the sewage grate wing so move to the activities of the mud when the material mixed together with the preheated grate wing the heat to the material so that part of the evaporation. At the same time the wing attachment materials filed so that repeated materials and hot air convection and contact heat exchange. At the same time cleaning device buried in the material along the arc-shaped lifting plate side of the downturn the lifting plate wall adhesion material swept down. When the cleaning device with the cylinder turned to the vertical line and the arc lifting plate on the back of the drag adhering to the lifting plate wall The material is swept down. With the continuous rotation of the cylinder so that part of the evaporation further drying sludge. At the same time cleaning device of sludge pellet also played a role in breaking enhances the drying speed and final sludge after drying into loose materials of low water discharged from the discharge port.
