Float sludge eliminating device of radial-flow sedimentation tank

Abstract

The invention discloses a float sludge eliminating device of a radial-flow sedimentation tank. The device comprises a sedimentation tank outer base, a central rotary support is rotatably connected tothe middle of the sedimentation tank outer base, a bridge frame is fixedly connected to the upper portion of the central rotary support, and an annular water pipe is fixedly connected to the upper surface of the bridge frame. A fan-shaped spray head is in threaded connection with the lower portion of the annular water pipe, the two ends of the bridge frame are fixedly connected with power trolleyassemblies, the two ends of each power trolley assembly are fixedly connected with fixing bases, and sliding wheel assemblies are slidably connected with the interiors of the fixing bases. According to the float sludge eliminating device for the radial-flow type sedimentation tank, through the cooperative arrangement of the annular water pipe, the fan-shaped spray heads and the water pump, the float sludge eliminating device for the radial-flow type sedimentation tank has the effect of effectively eliminating float sludge, and through the cooperative arrangement of the sedimentation tank outerbase, the sliding wheel assembly, a speed increasing box and a water pump, the float sludge eliminating device of the radial-flow sedimentation tank has the effect of saving energy by utilizing the existing power to drive the float sludge eliminating device.

Description

technical field [0001] The invention relates to the technical field of sewage discharge reduction, in particular to a device for eliminating floating mud in a radial flow sedimentation tank. Background technique [0002] For radial flow sedimentation tanks, the plane of the tank is mostly circular, and there are also square ones, with a diameter (or side length) of 6-60m and a maximum of 100m. The water depth around the pool is 1.5-3.0m, and the slope of the pool bottom should not be less than 0.05. The water inlet pipe in the center of the pool enters the pool, and flows slowly toward the periphery of the pool along the radial direction. The suspended matter settles in the flow and enters the sludge hopper along the slope of the bottom of the pool. The clarified water overflows from the pool to the drain. The rotary sludge scraper collects sludge, and the scraper of the sludge scraper scrapes the sludge that sinks to the bottom of the pool to the sludge bucket in the center...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for removing floating mud in a radial flow sedimentation tank, which has the advantages of effectively eliminating floating mud and utilizing the existing power-driven device for eliminating floating mud to save energy, etc., and solves the problem of floating mud With the rotation of the bridge frame, the slag baffle plate does not work and cannot be eliminated, and the device for removing floating mud requires additional power devices, resulting in a waste of resources.
