Introduction of equipment and technology of domestic sludge dryer

Introduction of equipment and technology of domestic sludge dryer. With the continuous development of urbanization, the production of domestic sludge is also increasing. With the continuous improvement of environmental protection policies, the treatment, disposal and comprehensive utilization of domestic sludge have become an important issue of national environmental protection. At present, in the drying market, new demand for sludge drying is emerging. The function of domestic sludge dryer is no longer just to complete drying operation. More users hope to get more and more assurance in reliability, stability and sustainability. ZJN, a high-tech enterprise that has always been in the forefront of high humidity and high viscosity solid waste and hazardous sludge drying technology, pays attention to the process research and development, production and manufacturing of energy-saving and environmental protection type domestic sludge dryer. With strict working attitude, rich R & D experience and innovative working concept, the "rotary harrow three-cylinder multiple-loop" ZJN domestic sludge dryer gradually goes It has entered the public's vision, and has been recognized by many well-known enterprises.

The composition of domestic sludge is complex, with high moisture content and high viscosity, which causes serious environmental sludge to accumulate for a long time. For large and medium-sized sewage treatment enterprises, a large amount of domestic sludge will be produced every day. Through the energy-saving and environmental protection of the ZJN domestic sludge dryer, the volume of dried sludge is greatly reduced, the recovery cost is effectively reduced, and the convenience of transportation is improved.

Equipment technology of domestic sludge dryer

The domestic sludge with high humidity and high viscosity is easy to agglomerate and stick to the dead corner of cylinder wall during drying. Long time use will affect the drying effect, equipment performance and service life. The ZJN domestic sludge dryer adopts new anti sticking technology and special three-layer sleeve structure, which effectively solves the drying problem of high wet viscosity sludge.

The main body of the dryer is composed of three nested concentric rollers. In order to enhance the drying effect and speed, the drum is also equipped with a "rotary rake crushing" breaking device and a combined lifting plate device. Keep the sludge in the mechanical state in the equipment. When the sludge enters the drum of domestic sludge dryer, it is first broken under the action of the "rotary rake crushing" device, and is quickly "thrown" and scattered in the equipment. At this time, the movable plate and movable grate type lifting device fixed on the cylinder wall will shake off and pop out quickly under the high-speed swing state, and then enter the center of the drum under the action of centripetal force, and the material will be like this In the process of repeated movement, it is gradually dispersed into smaller particles, and the drying process is completed under the action of hot air.
