Reinforcement sludge aerator, it adds the foraminate upside down funnel structure aeration of a cover band on the basis of former aeration tank
Cover, improves the trace of mixed liquor in aeration tank, and then substantially improves sludge aeration situation, increases oxygen utilization rate, saves aeration
Energy consumption.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of reinforcement sludge aerator, including aeration tank, aeration head, water inlet pipe, aeration cover, outlet pipe and sludge reflux
Water inlet pipe is installed on pipe, aeration tank upper end side wall, water inlet pipe is L-type, is made up of horizontal segment and vertical section, vertical section is located at aeration
In pond, and setting emptying stomata at aeration cover, aeration cover top center is cased with water inlet pipe vertical section, aeration cover cover is circumferentially
Direction is uniformly provided with the aperture that at least two row's size identicals are vented aqueous mixtures；Aeration cover can glide in water inlet pipe vertical end
It is dynamic；Water inlet pipe opposite side installs outlet pipe；Aeration head is placed in aeration tank bottom close to center, aeration tank bottom connection sludge
Return duct.
Further, aeration cover is upside down funnel structure, and its plane projection area is about the three of aeration tank plane projection area
Between 1/1 mono- to two.
Further, water inlet pipe vertical section end sets the anti-disconnection for preventing that aeration cover from coming off.
Further, it is anti-to disconnect as raised or pin.
Further, outlet pipe upper surface is less than water inlet pipe lower surface.
Further, water inlet pipe is plastic tube, glass tube, acrylic pipe or pvc pipe.
Further, aeration cover is more than the plastics or glass of water for density.
The invention has the advantages that and advantage：
1. the present invention sets aperture in aeration cover cover, improve the trace of mixed liquor in aeration tank, and then substantially improve dirt
Mud is aerated situation, while setting anti-disconnection to prevent aeration cover from departing from water inlet pipe in water inlet pipe end.
2. using the structure of the present invention, sludge stream vector is reduced, while reducing the accumulation of aeration tank bottom cone surface sludge.
3. the present invention can increase oxygen utilization rate, aeration energy consumption is saved, simple in construction, easy for installation, cost is low, efficiency
It is high.

Embodiment
The present invention is further described in detail below in conjunction with the accompanying drawings.
Embodiment 1：As shown in figure 1, a kind of reinforcement sludge aerator, including aeration tank 6, aeration head 7, water inlet pipe 1, exposure
Gas hood 3, outlet pipe 2 and mud return line 8, the bottom of aeration tank 6 are vertebral body, and aeration head 7 is placed in aeration tank bottom close to center
Position, the bottom centre position of aeration tank 7 sets mud return line 8.Water inlet pipe 1 is installed, water inlet pipe 1 is on the upper end side wall of aeration tank
L-type, is made up of horizontal segment and vertical section, and vertical section is located in aeration tank 6, and water inlet pipe vertical section is cased with aeration cover 3, aeration cover 3
It can be slided up and down in the vertical end of water inlet pipe 1；The end of water inlet pipe 1 is raised or pin provided with anti-disconnection 10, anti-disconnection 10, to prevent exposing
Gas hood 3 is dropped when being aerated and stopping, and emptying stomata is set at aeration 3 top centers of cover, and aeration 3 covers of cover are along the circumferential direction uniform
