Description

Technical Field

[0001] The utility model relates to the technical field of sewage filtration, in particular to a filtering structure for filtering solid impurities in sewage. Background Art

[0002] The initial process of sewage treatment is to physically separate the sewage, separating the solids and liquids in the sewage, so as to facilitate their subsequent treatment. The existing sewage physical separation mainly relies on filter nets, which use gravity to promote the flow of sewage and use filter nets to isolate the solids and liquids in the sewage.

[0003] At present, the methods used for sewage solid filtration mainly include sedimentation, chemical, microbial treatment, etc., and then a filter is used to filter the solid matter in the sewage. However, these methods require a relatively large equipment investment to treat sewage, and the treatment cycle is relatively long and the treatment cost is high. At the same time, since the solid impurities in the sewage contain many recyclable metal impurities, the existing filtration devices lack the ability to recycle the metal impurities.

[0004] To this end, we propose a filtering structure for filtering solid impurities in sewage. Utility Model Content

[0005] The purpose of the utility model is to provide a filtering structure for filtering solid impurities in sewage to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filtering structure for filtering solid impurities in sewage, comprising a filter barrel, a recovery barrel, a first return pipe and a second return pipe, a recovery barrel being installed at one side of the filter barrel, a first return pipe being fixedly connected to the outer surface of the filter barrel, and the other end of the first return pipe being fixedly connected to the recovery barrel, a second return pipe being fixedly connected to the outer surface of the filter barrel, and the other end of the second return pipe being fixedly connected to the recovery barrel.

[0007] Preferably, a fixed gear is installed at the center of the top surface of the filter barrel, a rotating gear is installed on the top surface of the filter barrel, and the rotating gear is meshingly connected with the fixed gear, a rotating drum is installed on the top surface of the rotating gear, a connecting rod is installed on the outer surface of the rotating drum, a motor bracket is fixedly connected to the top surface of the filter barrel, a rotating motor is installed on the top surface of the motor bracket, and the output end of the rotating motor is fixedly connected to the connecting rod.

[0008] Preferably, a movable groove is opened on the top surface of the filter barrel, a movable rod is installed inside the movable groove, and the top end of the movable rod is fixedly connected to the rotating gear, a magnetic plate is installed on the bottom surface of the movable rod, and a magnetic sheet is installed on the bottom surface of the magnetic plate.

[0009] Preferably, a fixing frame is fixedly connected to the outer surface of the movable rod, a brush plate is symmetrically mounted on the bottom surface of the fixing frame, and a brush is mounted on the bottom surface of the brush plate.

[0010] Preferably, a support column is installed inside the filter barrel, a first filter plate is installed on the outer surface of the support column, a second filter plate is installed on the outer surface of the support column below the first filter plate, a baffle is fixedly connected to the surface of one side of the first filter plate and the second filter plate, and a scraper is fixedly connected to the top surface of the baffle.

[0011] Preferably, a rotating rod is rotatably installed inside the recovery cylinder, a spiral blade is fixedly connected to the outer surface of the rotating rod, a filter hole is opened inside the spiral blade, a driving motor is installed on the top surface of the recovery cylinder, and the output end of the driving motor is fixedly connected to the rotating rod.

[0012] Preferably, a control panel is installed on the outer surface of the filter barrel, and the rotating motor and the driving motor are electrically controlled and connected by the control panel.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the rolling gear installed on the top surface of the filter barrel cooperates with the fixed gear, and when the rotating motor is running, the rolling gear is driven to rotate through the connecting rod. Since the rolling gear is meshed and connected with the fixed gear, the rolling gear rotates and rotates at the same time. The self-rotation of the rolling gear drives the magnetic plate and the magnetic sheet installed at the bottom to rotate, so that the metal impurities on the first filter plate can be adsorbed and the metal impurities adsorbed on the magnetic plate can be scraped off when passing through the scraper. The brush plates and brushes installed on both sides of the magnetic plate can prevent clogging and clean the surface of the first filter plate, and flatten the solid impurities accumulated in one place, so as to better adsorb the metal impurities. Through the cooperation of the spiral blades and the rotating rod, when the residual impurities are screened out on the surface of the second filter plate, they can be transported to the filter barrel in the mixing box through the cooperation of the spiral blades and the rotating rod for recycling and secondary filtration to avoid omissions.
