Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a sludge cyclone purification device. Background Art

[0002] The sludge cyclone purification device is a fluid machinery widely used in industrial production, which is used for sludge sorting, grading, separation, concentration, washing, clarification, desludging and degassing. The sludge separated by the sludge cyclone purification device must meet two necessary conditions: one is that the mixed fluid must have pressure energy; the other is that there must be a density difference between the mixed materials, and the greater the density, the better the separation effect. Muddy sewage generally consists of water and suspended solids, which can form a relatively stable suspended emulsion system. Using a cyclone to treat muddy sewage is to use the difference between mud and water in muddy sewage to achieve separation of different densities through centrifugal sedimentation. The sludge cyclone purification device collects the solid suspended matter and water in the water through centrifugal sedimentation, and ensures that no excessive water flow loss is caused. In the sludge treatment process, the link of separating suspended matter and supernatant in sewage plays an increasingly important role in sewage treatment. In order to achieve better purification effect, it is necessary to improve and optimize the current sludge cyclone purification device.

[0003] The existing sludge cyclone purification device is mainly in the form of a tank body and is equipped with a cyclone separation device, such as the high-efficiency cyclone sewage purifier disclosed in Chinese Patent Announcement No. CN211521810U, which is equipped with a cyclone device, a filter device, etc., and a conical sludge gathering pool at the bottom. Under the action of pressure, sewage enters the cyclone device through the water inlet pipe along the tangent direction of the cyclone device. Under the action of centrifugal sedimentation, the substances with larger specific gravity are discharged from the lower end of the cyclone device, and the substances with smaller specific gravity overflow from the top of the cyclone device, and flocculate and precipitate at the filter device into the sludge gathering pool at the bottom, and are discharged from the sewage pipe. However, the overall height of the tank device is relatively high, the volume is too large, and the internal structure is complicated. There is only one cyclone separation device to process the sludge, resulting in a slow sludge deposition speed, poor effect, and incomplete separation. At the same time, the overall shutdown and maintenance of the filter device are also required during the later maintenance, which affects the use. Utility Model Content
