Gap oil slick-removing mechanism for sewage treatment

Abstract

The invention discloses a gap oil slick-removing mechanism for sewage treatment, and relates to the technical field of sewage treatment. The gap oil slick-removing mechanism for sewage treatment comprises a pipeline, wherein the pipeline communicates with a distributing pipe, a three-way pipe structure is formed through the pipeline and the distributing pipe, and a roller is arranged at a junctionof the pipeline and the distributing pipe; the roller is connected with a power mechanism for driving the roller to perform axial rotation, a fan-shaped notch is formed in the roller, and a pressureplate for limiting movement of the roller is fixedly connected to the junction of the pipeline and the distributing pipe; and the pipeline does not communicate with the distributing pipe when the bottom surface of the fan-shaped notch is attached to the pressure plate, and the pipeline communicates with the distributing pipe when the bottom surface of the fan-shaped notch is separated from the pressure plate. The gap oil slick-removing mechanism has the advantages that oil slick is blocked through a buoyancy block during flow of sewage, the time consumption is small, and when the stored oil slick is excessive, oil is removed through cooperation of the buoyancy block so as to discharge materials; and the cooperation efficiency among the mechanisms is high, and the oil slick is removed efficient and fast.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a gap oil removal mechanism for sewage treatment. Background technique [0002] Kitchen sewage contains a large amount of animal and vegetable oil, which is miscellaneous oil. For experienced chefs, they know that miscellaneous oil has a better flavor, so it is necessary to prevent this oil from being used to flow back into the food market. The conventional water-oil separation methods are: Natural sedimentation, centrifugal separation, air flotation, coarse-grained coalescence, filtration, adsorption, membrane separation, etc., but most of the above methods are time-consuming and costly, and are not suitable for rapid processing. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems, and propose a gap oil removal mechanism for sewage treatment. [0004] In order to achieve the above object, the present inventi...
