Connecting member having buckling device and used for aerator

Abstract

The invention provides a connecting member having a buckling device and used for an aerator. The connecting member comprises: two semi-arc-shaped clamping hoops with the same structure, wherein the left side and the right side of one end of the clamping hoop are respectively provided with a clamping claw and a positioning rod, the axis of the inner arc surface of the clamping claw coincides with the axis of the positioning rod, the clamping claw of one clamping hoop is clamped with the positioning rod of the other clamping hoop, the inner arc surface of the clamping hoop is provided with a positioning block clamped with a positioning groove of a pipeline, the outer arc surface of one clamping hoop is provided with a first connecting table with internal threads, and the outer arc surface ofthe other clamping hoop is provided with a second connecting table with external threads; and a buckling device for fixing the two clamping hoops, wherein a wedge-shaped block is arranged at one end,far away from the clamping jaw, of the clamping hoop, the buckling device comprises a mother buckle connected with the wedge-shaped block of one clamping hoop in a clamped mode, the mother buckle isdetachably connected with a son buckle connected with the wedge-shaped block of the other clamping hoop in a clamped mode, and the mother buckle is further provided with a secondary clamping locking buckle to realize a clamping locking structure for positioning and fixing the two clamping hoops. The connecting member of the invention can ensure the reliable connection between an aerator and a pipeline.

Description

technical field [0001] The invention relates to the technical field of an aerator and its accessories, in particular to a connector for an aerator with a buckle device. Background technique [0002] In the field of sewage treatment, the aerator has a great influence on the oxygen transfer efficiency and the operating cost of sewage treatment. The domestic development and application of aerators began in the mid-1980s, and the representative ones are: perforated tube aerators, corundum aerators, disc microporous aerators, tube aerators, jet aerators, Diffuse aerator, cyclone aerator, etc. [0003] The aerator usually needs to be installed on the pipeline. The clamp-type connection between the aerator and the pipeline in the prior art is mostly positioned and fixed in the form of stainless steel bolts. This method has the following disadvantages: [0004] 1. The cost is too high; [0005] 2. Stainless steel bolts are severely corroded in the sewage with high chloride ions, ...

AI Technical Summary

Problems solved by technology

[0004] 1. The cost is too high;

[0005] 2. Stainless steel bolts are severely corroded in the sewage with high chloride ions, resulting in connection failure;

[0006] 3. Stainless steel bolts are complex, time-consuming, inconvenient, and inefficient during processing, assembly, transportation, and on-site installation

[0008] 1. There is no locking structure, and the latch and pin are easy to fall off;

[0009] 2. The maximum opening angle of the clamp is limited, and the working conditions are limited;

[0010] 3. Unreasonable structure and laborious installation
