Description

Sewage treatment pond floats mud cleaning device

Technical Field

The utility model relates to a sewage treatment technical field, concretely relates to sewage treatment pond floats mud cleaning device.

Background

In the sewage treatment process, floating mud and floating objects are always on the surface of the sewage treatment tank, so that the sewage treatment effect is influenced. In order to remove floating mud and floating objects on the surface of a sewage treatment tank, in the prior art, the floating mud and floating objects on the surface of the sewage treatment tank are removed by a floating mud and slag collecting and removing device (also called a mud scraping and sucking machine) of the sewage treatment tank. The existing device for removing the floating sludge and the collected edges of the sewage treatment tank rotates around a central shaft through a rotating bridge, drives a hanging plate to push floating sludge and floaters to a floating sludge discharge opening at the side of the tank, and removes the floating sludge.

However, the existing method for removing floating mud has the problems that the rotating speed of the rotating bridge is slow, the centrifugal force of the scraper for pushing floating mud residues and floating objects is weak, the floating mud and the floating objects are often not scraped to the position of a floating mud residue discharge opening (a horizontal water discharge opening of a sewage treatment tank) and are blown away by wind, and the floating mud and the floating objects are difficult to effectively remove.

The utility model patent with application number CN201720189213.2 discloses the following technical scheme of "sewage treatment pond superficial mud sediment collection device": the floating sludge collecting device of the sewage treatment tank comprises a central shaft, a rotating arm, a walking bridge, a collector and a rotating arm driver; the walking bridge is positioned between the two sludge discharge openings of the sewage treatment tank, and two ends of the walking bridge are respectively connected with the central shaft and the side wall of the sewage treatment tank; the collector is arranged at the top of the walking bridge and reciprocates along the length direction of the walking bridge; one end of the rotating arm is connected with the central shaft through a revolute pair, and the other end of the rotating arm is connected with a rotating arm driver; the rotating arm is driven by the rotating arm driver to rotate clockwise or anticlockwise around the central shaft; the bottoms of the rotating arms and the walking bridge are deep into the sewage; and filter screens are respectively arranged in the longitudinal direction of the rotating arm and the traveling bridge.

According to the scheme, the collector which moves in a reciprocating mode is arranged on the top surface of the walking bridge, so that the floating sludge pushed by the rotating arm is pushed to the slag discharging port, and therefore the discharged slag is effectively removed. However, the above scheme has a complex structure and low removal efficiency, and the collector in reciprocating motion is easy to push scum in the opposite direction; in addition, the pushing and the collecting of the floating sludge are carried out in two steps, the process is complicated, and the popularization is not high.

Therefore, it is necessary to develop a new device for cleaning floating mud in sewage treatment tank.
