Description

A new type of membrane bioreactor quick-installed aeration joint

technical field

The utility model relates to the technical field of domestic sewage and industrial wastewater treatment equipment, which is a biological reaction wastewater treatment equipment combined with activated sludge method and biofilm, and is also a new type of membrane bioreactor quick-installed aeration joint.

Background technique

At present, the aeration joints for membrane bioreactors on the market are generally connected by clamps. This connection method not only affects the sealing performance, but also the accessories can only be used once, which is a great waste, especially because of poor sealing performance, which affects the aeration effect. Although there is also a method of directly welding together by electric welding in the existing market, although this solves the sealing problem, it can only be used for one time, which increases the maintenance cost. Normal use of membrane bioreactors.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 1, the utility model it comprises the injector 1 that is arranged upwards, and injector 1 top is mixing chamber 2, and the bottom is suction chamber 3, and mixing chamber 2 communicates with suction chamber 3. An air inlet 10 is provided on the side wall of the suction chamber 3, and a nozzle head 4 is arranged inside the suction chamber 3. The lower end of the nozzle head 4 is located outside the lower end of the injector 1. The head 4 enters the suction chamber 3, and enters the reactor after being mixed in the suction chamber 3 and the mixing chamber 2. The utility model is provided with a ring of protrusions 5 at the lower end of the nozzle head 4, and a rotary joint 6 with an internal thread at the lower end is installed on the protrusions 5. The rotary joint 6 can be fixed on the lower end of the nozzle head 4, or can be movably installed on the protrusion 5 at the lower end of the nozzle head 4, and can be rotated with the lower end of the nozzle head 4 as a rotating shaft. The upper part of the outer wall of the above-mentioned protrusion 5 is a tapered surface, which matches the tapered mounting surface in the inner hole of the rotary joint 6, so that the rotary joint 6 will not fall off from the nozzle head 4, and can be placed on the rotary joint 6 and the bottom of the rotary joint 6. When the swivel pipe 8 is installed, the tightness between the swivel head 6 and the nozzle head 4 is ensured. A water inlet pipe 7 is provided below the injector 1 of the utility model, and a screw connection pipe 8 is arranged on the water inlet pipe 7. The outer wall of the rotation connection pipe 8 is provided with an external thread structure, and the external thread structure is matched with the internal thread in the rotary joint 6. , to realize the installation and connection of the nozzle head 4 and the water inlet pipe 7. The lower end of the nozzle head 4 and the upper end of the swivel pipe 8 are matching truncated circular interfaces. During installation, the frustum-shaped joints squeeze each other to achieve tight installation and good sealing. The utility model is covered with a ring of rubber gasket 9 on the rotary joint 6, which can play a buffering role when the rotary joint 6 and the rotary joint 8 are installed, and strengthen the sealing between them.

Other unexplained parts involved in the utility model are the same as the prior art.
