Oil removal and skimming equipment for sewage treatment

Abstract

The invention discloses oil removal and skimming equipment for sewage treatment. The equipment comprises a circulating groove, wherein first limiting grooves are symmetrically formed in the side wallof the circulating groove, a first floating block and a second floating block are slidably connected into the two first limiting grooves correspondingly, a driving motor is installed on the first floating block, a rotating roller is horizontally and fixedly connected to the output end of the driving motor, a containing groove is coaxially formed in the middle of the rotating roller, and a circulating pipe is horizontally and fixedly connected to the second floating block. According to the invention, by arranging a permanent magnet plate and a permanent magnet block, magnetic repulsion betweenthe permanent magnet plate and the permanent magnet block is used for driving the permanent magnet plate to move, so that sewage transfer can be completed, oil stains and dross on the liquid level ofsewage can be continuously intercepted, fished and transferred without manual work, and the working efficiency is high; and under the interception action of a rotating roller, blockage can be prevented, and leakage of oil stains and dross can be prevented, so that trouble and labor can be saved, and the equipment is high in applicability and can be used for treating sewage with different quantities of water.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an oil removal and scum removal equipment for sewage treatment. Background technique [0002] Urban domestic sewage often contains a large amount of grease and scum. At present, there are two main treatment methods for it. One is to add chemicals to decompose and remove the grease and then intercept and salvage the scum. The other is to use Manual interception and salvage, because the first treatment method requires a large amount of chemical agents, the second method is basically used in many large sewage treatment plants for sewage degreasing. [0003] However, in actual operation, because the sewage is always in a flowing state, it is difficult to salvage manually, and the salvage efficiency is low. At the same time, the working environment of the workers is harsh, and the harmful gas in the sewage will cause great harm to the health of the workers. Structures such a...
