Roller centrifugal type environment-friendly treatment device for sludge dewatering

Abstract

The invention discloses a roller centrifugal type environment-friendly treatment device for sludge dewatering. The device comprises a fixing base plate; a first supporting frame is arranged on the left side of the upper end of the fixing base plate; a guide base is arranged at the upper end of the first supporting frame; a driving shaft is arranged in the middle of the guide base; a first rotatingdisc is arranged at the right end of the driving shaft; a second supporting frame is arranged on the right side of the upper end of the fixing base plate; a driven shaft is arranged in the middle ofthe second supporting frame through a bearing; a second rotating disc is arranged at the left end of the driven shaft; an outer cylinder is arranged between the first rotating disc and the second rotating disc; a first motor is arranged on the left side of the lower end of the outer cylinder; a driving belt wheel is arranged at the upper end of the first motor; a driven belt wheel is connected tothe right end of the driving belt wheel through a belt; a main shaft is arranged at the upper end of the driven belt wheel; an inner cylinder is arranged at the upper end of the main shaft; and a counter shaft is arranged in the main shaft. According to the device, sludge can be efficiently dewatered by utilizing the centrifugal force, the dewatering efficiency of the sludge can be improved, and meanwhile, the dewatered sludge can be quickly poured out.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a drum centrifugal sludge dehydration environmental protection treatment device. Background technique [0002] Sludge is the product of sewage treatment, which is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloidal sludge, etc. The main characteristics of sludge are high water content (up to 99%), high content of organic matter, easy to rot and smell, and the particles are finer, the specific gravity is smaller, and it is in a colloidal liquid state. It is a thick substance between liquid and solid, which can be transported by pump, but it is difficult to separate solid and liquid by sedimentation. Sludge usually refers to the precipitated sludge, particulate matter and floating matter produced when wastewater is treated by physical, chemical, physicochemical and biological methods. Sludg...

AI Technical Summary

Problems solved by technology

At present, the most used sludge dewatering machine in the market is the screw stacking sludge dewatering machine, but the screw stacking sludge dewatering machine is easy to cause sludge to block the filter screen when it is used, which greatly reduces the dehydration efficiency. After sludge dehydration, it is difficult to take out and recycle the dehydrated sludge, which seriously affects the quality of sludge treatment in the later stage, and is not very practical.
