Description

Technical Field

[0001] The utility model relates to the technical field of dehydrators, in particular to an energy-saving and environment-friendly sludge dehydrator. Background Art

[0002] With the continuous improvement of productivity, more and more wastewater is discharged from industry and life. The discharge of wastewater has a great harm to the pollution of the environment. The discharge of wastewater into lakes will also cause the death of a large number of aquatic organisms. Therefore, the water pollution of lakes is imminent. How to control the water pollution of lakes has become an important issue of environmental protection. In order to better control the pollution of lakes and other water bodies, it is usually necessary to dehydrate the sludge at the bottom. The sludge dewatering machine is a continuously running sludge treatment equipment. It is popular with the public because of its low water content in the sludge, stable operation, low energy consumption, relatively simple control and management, and easy maintenance.

[0003] Existing sludge dewatering machines are not easy to filter and disinfect the discharged wastewater before discharging it. Harmful substances may remain in the wastewater, which will pollute the water quality and endanger the surrounding environment when discharged into the environment.

The utility model is used to store wastewater separated from the sludge by arranging a water tank, and the sludge is made into blocks by arranging a discharge box, and a power source is provided for the operation of the spiral pusher by arranging a motor, a first bevel gear, a first rotating shaft and a second bevel gear. By arranging the second rotating shaft, the dewatering machine has double spiral dewatering, which improves the dewatering effect of the sludge and solves the problem of poor dewatering and separation effect of the existing sludge dewatering machine.

[0005] Although the above patent has achieved the goal of providing a second rotating shaft to enable the dewatering machine to have double-spiral dewatering, thereby improving the dewatering effect of the sludge and solving the problem of poor dewatering and separation effect of the existing sludge dewatering machine; however, the device lacks pretreatment of the wastewater. During pretreatment, flocculants are generally required to be added for precipitation so that subsequent filtration, precipitation or other treatment steps can be carried out more effectively.

[0006] Therefore, it is necessary to invent an energy-saving and environmentally friendly sludge dewatering machine to solve the above problems. Utility Model Content
