Description

Can promote aeration systems and sewage treatment device

Technical Field

Background

The aeration system is one of the most important components in the sewage treatment equipment, and because sludge sedimentation can be formed in the sewage treatment process to block the aerator of the aeration system, the aeration system needs to be overhauled and the aerator needs to be replaced at intervals (less, half a year and more, two or three years according to the sewage treatment condition).

The conventional maintenance method is to discharge sewage in the sewage treatment tower, and then workers enter the tower to maintain and replace the aeration system, and the method has the defect that the sewage treatment operation is relatively delayed, generally, the maintenance is performed once, the time is half a day, and more, the maintenance is performed for several days.

In order to avoid the influence on sewage treatment operation because sewage does not need to be discharged when the aeration head is overhauled, the aeration system is made into a lifting type in the current general method. For example, the vertical lifting type microporous aerator comprises a plurality of tubular aeration heads arranged on an annular gas distribution pipe, a lifting guide rail and an underwater coupling device, and four parts of two movable manual lifting machines. When an aeration head in the aeration tank needs to be overhauled, the bolt of the air falling pipe is unfastened, the stainless steel wire rope is pulled by two movable manual elevators which are respectively arranged at two sides of the annular pipe to be overhauled of the aeration tank, the annular gas distribution pipe is uniformly lifted to the water surface along the lifting guide rail, and then workers maintain and replace the aeration system. The method has the defects that impurities in the sewage can be gathered on the guide rail and are clamped between the pulley block and the guide rail, so that the aeration system cannot be smoothly lifted or lowered, and if the aeration system is directly lifted by a rope without adopting the guide rail, the aeration system is unstable in the lifting process and is easy to transversely move and collide with the tower wall to be damaged.

The utility model provides a liftable aeration system, which is arranged in a sewage treatment container 1, wherein the sewage treatment container 1 comprises a sewage treatment tower, a sewage treatment tank and the like, the liftable aeration system does not adopt a traditional guide rail type liftable aeration system, but connects an air supply pipe 7 through an air inlet pipe 9 which is vertically arranged, the air inlet pipe 9 can supply air for an aerator 8 on one hand, and can be provided with a locking mechanism 5 on the air inlet pipe 9 on the other hand, and the air inlet pipe 9 is locked through the locking mechanism 5 to realize the fixation of the aeration system. After the locking mechanism 5 is unlocked and locked, the aeration system can automatically float out of the water surface by virtue of the buoyancy force applied by the aeration system, the use reliability and the durability of the aeration system are higher than those of the traditional guide rail type lifting aeration system, and the practicability is good.

Referring to fig. 1, in an embodiment of the utility model, liftable aeration system includes air supply pipe 7 and locates aerator 8 on air supply pipe 7, as shown in fig. 2 and 3, air supply pipe 7 locates the bottom of sewage treatment container 1, and is the annular distribution to make aerator 8 evenly distributed in each region of sewage treatment container 1 bottom, vertically install intake pipe 9 on the air supply pipe 7, supply air to air supply pipe 7 through intake pipe 9, it is equipped with locking mechanism 5 to press from both sides in the intake pipe 9, locking mechanism 5 includes mounting bracket 4, clamp 52, lead screw 53 and locking motor 51, mounting bracket 4 fixed mounting is in the top of sewage treatment container 1, clamp 52 cover is established on intake pipe 9.
