Description

Wind power skimming system for sedimentation tank

Technical Field

The utility model relates to a wind-force skimming system for sedimentation tank belongs to the sewage treatment field.

Background

Along with the rapid development of industrial production in China, the generation of wastewater is increased day by day, two modes of manual slag removal and mechanical slag removal are adopted as the slag removal modes on the surface of the secondary sedimentation tank of the existing sewage treatment plant, and the manual salvage of the floating slag on the surface of the secondary sedimentation tank is large in engineering quantity and high in cost and has certain danger. Therefore, most sewage treatment plants adopt a mechanical slag removal mode, the mechanical slag removal equipment usually adopts a slag removal method similar to cleaning for scum on the surface of a sedimentation tank by a slag scraping arm or a slag scraping plate which is formed by extending the center of a secondary sedimentation tank outwards, the scum on the surface is cleaned along with the rotation of the slag scraping arm or the slag scraping plate, and the secondary sedimentation tank sludge is prevented from being stirred, so the efficiency is low due to the control of the rotation speed of the slag scraping arm or the slag scraping plate, and meanwhile, for a small-sized secondary sedimentation tank, a large-sized slag scraping plate is not necessary, the investment cost is high, and the operation and maintenance cost is also high.

Therefore, the wind power skimming system for the sedimentation tank adopts a wind power deslagging mode, and is simple in structure, low in investment cost, simple and convenient to operate and maintain, and convenient to install and use.

Preferably, the connecting pipes are arranged in parallel; with connecting pipe parallel arrangement, form stable wind pressure, utilize the wind pressure to blow step by step the dross, can be more comprehensive promote the dross to the sediment inslot, avoided the accumulation of the remaining dross in dead angle.

Preferably, a main pipe is arranged at a water outlet of the sedimentation tank, the main pipe is communicated with a plurality of connecting pipes, and the end part of the main pipe is communicated with an air blower.

Preferably, the lifting slag trap is connected with a motor arranged on the wall of the sedimentation tank, and the lifting slag trap is controlled to lift through the motor, so that the collection and the cleaning of the residues are flexible and convenient.

Preferably, one side of the slag groove relative to the lifting type slag baffle is provided with a first baffle, so that scum can be conveniently and uniformly cleaned.

The utility model discloses following beneficial effect has: for current mechanical scarfing cinder equipment, the utility model discloses a wind-force skimming system has reduced the volatility to sewage production, has effectively prevented mud from swashing up from the sedimentation tank bottom to the sediment of the mud of being convenient for reduces short sludge settling time. In addition, the angle between the branch pipe and the horizontal plane is 45-60 degrees, so that the slag removing area is enlarged, the scum is more comprehensively cleaned, and the scum flowing out along with water flow can be effectively reduced; the parallel arrangement of connecting pipe can also form and stabilize the wind pressure, makes the clearance more comprehensive, does not keep the dead angle.
