AI Technical Summary

Technical Problem

When existing drum filters treat water containing floating objects, they are prone to problems such as increased filtration burden, blocked water inlet pipes and difficult discharge of floating objects.

Method used

A sinking drum filter is designed to intercept floating objects by setting up a filter net in the inlet pool, and the gear ring is used to drive the filter drum to rotate. Combined with the use of the flushing tube and high-pressure nozzle, it can effectively clean up the adherent debris of the inner wall of the filter drum.

Benefits of technology

It effectively reduces the workload of the filter drum, improves the filtration efficiency, simplifies the cleaning process of floating objects, and avoids the problems of blockage of water inlet pipes and the difficulty of floating objects being discharged.

Abstract

A sunken drum filter comprises a water inlet tank, a filter tank and a drum filter, a water inlet is arranged in the water inlet tank, a layer of filter screen is arranged below the water inlet in the water inlet tank, the filter tank is arranged on one side of the water inlet tank, and the drum filter is rotatably arranged in the filter tank through a mounting frame. The drum filter is composed of a filtering drum and a motor driving the filtering drum to rotate, the filtering drum is rotationally connected into a rotating shaft, the two ends of the rotating shaft penetrate through the filtering drum and are fixedly installed in the installation frame, a gear ring surrounding the outer circle of the filtering drum is arranged outside one end of the filtering drum, and the motor is installed in the installation frame. A driving gear meshed with the gear ring is mounted on the power output shaft, a clamping rod is mounted at the top of the mounting frame, a flushing pipe is mounted in the clamping rod in a clamping manner, and the flushing pipe is positioned above the outer part of the filtering rotary drum and is symmetrical to a dirt collecting groove in the filtering rotary drum. The filtering device has the advantages of improved filtering effect, stable filtering and the like.
