Abstract

The invention relates to the technical field of sewage treatment, in particular to an oil-water separation device with a sedimentation function for sewage. The invention discloses an oil-water separation device with a settling function for sewage. The oil-water separation device comprises a settling tank, a supporting plate, a double-helix screw rod, a first reversing mechanism, a driving mechanism, a second reversing mechanism and an oil discharge mechanism, the first reversing mechanism comprises an upper sliding ring, a middle sliding ring, a lower sliding ring and a switching assembly. The driving mechanism is configured to enable the first gear ring and the second gear ring to be meshed with the reversing gear under the action of buoyancy of liquid. The second reversing mechanism is configured to enable the upper sliding ring to descend under the action of the second spiral groove after the first gear ring and the second gear ring are meshed with the reversing gear, and then the supporting plate is driven to descend. The oil discharging mechanism is installed on the supporting plate and used for discharging floating oil. The invention provides an oil-water separation device with a sedimentation function for sewage, and aims to solve the problems that an existing device cannot sense the height of an oil level, cannot ensure that guided oil has relatively low water content and is poor in oil-water separation treatment capacity.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an oil-water separation device for sewage with a settling function. Background technique [0002] Oily sewage is produced in the processes of oil exploration, refining, petrochemicals, oil storage and transportation, tanker accidents, shipping, vehicle cleaning, machinery manufacturing, and food processing. Oil pollution is extremely harmful to environmental protection and ecological balance. Today, there are many oil-water separation technologies, and the commonly used methods include gravity separation method, coarse-grained method, filtration method, air flotation method, adsorption method, membrane separation, ultrasonic method, chemical method, biological method and other technologies. [0003] Among them, in the gravity separation method, the principle of gravity makes the suspended matter in the mixed solution separate from the water, and the proportion of the mi...
