Municipal sludge is the excess sludge that the municipal sewage plant disposes of sewage and produces in the process, builds and operation along with wastewater treatment in China factory is large-scale, and sludge treatment, handling problems have become one of important factor of restriction Industry Quick Development.Mud contains various pathogenic micro-organisms, heavy metal and poisonous and harmful compound, has the secondary pollution risk, and has disguise and hysteresis quality.2010,3,800 ten thousand tons of the sludge quantities of China, year increase by 10% ~ 15% after estimating.At present, the municipal sludge 44.8% of China is agricultural, and 31% landfill is afforested, burned and respectively accounts for about 3.5% with rubbish mixing landfill, and residue 13.7% is rationally disposed.
Domestic present ﹠ Mud approach mainly contains burning, soil utilization and landfill etc.Burning is large because investing, and running cost is high, suits economically developed, and is populous, the area of land resource scarcity.Soil utilization and landfill all need sewage work's dewatered sludge is carried out could implementing after minimizing, the stabilization treatment.Wherein a most important step of minimizing drops to dewatered sludge below 60% from water ratio 75 ~ 80% exactly, dewatered sludge viscosity is large, is difficult to disperse, and washiness is present in the microorganism cells in the mud, be difficult for removing, water ratio be dropped to needs lot of energy and time several weeks below 60%.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of sludge granulator of effective reduction moisture percentage in sewage sludge.
For addressing the above problem, sludge granulator described in the utility model is characterized in that: it comprises support and places the motor with wheel box, hopper and mud grain shaped device on the described support; Described feed hopper bottom is provided with sludge carrier pipe, is provided with the mud extrusion axis in this sludge carrier pipe; One end of described this mud extrusion axis links to each other with the output shaft of described motor with wheel box, and its other end links to each other with described mud grain shaped device by the extrusion axis anchor; The output shaft of described motor with wheel box is provided with the power conversion wheel, and this power conversion wheel is connected with the power wheel I by belt; Described power wheel I is connected with the power wheel II by transmission rod, and this power wheel II is connected with transmission shaft by belt; Described transmission shaft termination is provided with cam; Described mud grain shaped device comprises cavity and places orifice plate and the cutting knife frame of described cavity bottom; Described cutting knife frame is provided with number row's steel wires, and the one side is provided with an end and is fixed on spring on the described orifice plate, and its opposite side is provided with trolley wheel, and this trolley wheel contacts with described cam.
The bottom of described support is evenly equipped with road wheel.
Described mud extrusion axis is screw shaft, and the one end links to each other by the gear engagement output shaft with described motor with wheel box.
The utility model compared with prior art has the following advantages:
1, owing to is provided with mud extrusion axis and mud grain shaped device in the utility model, therefore, can make dewatered sludge 16 ~ 18 ℃ of temperature, under relative humidity 60% condition, moisture percentage in sewage sludge can be dropped to below 60% from 75 ~ 80% within one week, satisfy landfill, During High-Temperature Composting to the requirement of moisture percentage in sewage sludge.
2, owing to be provided with orifice plate and cutting knife frame in the utility model mud grain shaped device, therefore, dewatered sludge of urban sewage plant can be made mud granule easily, and avoids the again adhesion of particle of making in the granulation process.
