Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sludge dehydration environmental protection device. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sludge is the product of sewage treatment. It is an extremely complex inhomogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. Since the sludge contains a large amount of sewage, a dewatering device is needed to separate the sludge and sewage for post-treatment.

[0003] Traditional dehydration equipment can only separate sewage and sludge. After separation, the sludge needs to be transferred by staff for drying process before it can be recycled, resulting in slow sludge drying efficiency and reduced sludge treatment efficiency. At the same time, the separated sewage contains impurities, which can easily affect the surrounding environment, resulting in a decrease in the quality of sewage treatment.

[0004] According to the publication number: CN219469892U, a sludge concentration and dehydration device includes a cylinder, a rotating shaft is connected between the inner walls at both ends of the cylinder through bearings, a motor is fixed to the outer wall of one side of the cylinder, one end of the output shaft of the motor is connected to the rotating shaft through a key, a variable pitch auger is welded to the outer wall of the rotating shaft, the outer wall of the bottom of the cylinder is provided with evenly distributed water-permeable holes, the outer wall of one side of the cylinder is provided with a discharge port, the discharge port is covered with an extrusion plate, a baffle is provided on the side of the extrusion plate away from the cylinder, and a spring is provided between the baffle and the extrusion plate. The utility model compresses and dehydrates the sludge through the variable pitch auger, and the elastic force of the spring causes the extrusion plate to generate pressure when the sludge flows out, so that the pressure on the sludge inside the cylinder during dehydration is increased, thereby achieving a better effect of sludge dehydration.

[0005] According to the dewatering device introduced above, only sewage and sludge can be separated. After separation, the sludge needs to be transferred by staff for drying process before it can be recycled, resulting in slow drying efficiency of the sludge and reduced sludge treatment efficiency. At the same time, the separated sewage contains impurities, which can easily affect the surrounding environment and lead to a decrease in the quality of sewage treatment. Therefore, we need to propose a sludge dewatering environmentally friendly device. Utility Model Content
