Problems solved by technology

[0005] The patent application number 201610998821.8 discloses an aeration device ( figure 1 ), the first rotating rod in the aeration device will cause the output shaft to swing when the force is uneven during stirring, and the rotating hole is fixedly arranged on the aeration box itself. When the swinging of the output shaft makes the output shaft and the rotating hole The force between them is seriously uneven, and long-term work will easily lead to the failure of the dynamic seal between the output shaft and the rotating hole, resulting in the leakage of the air delivery channel

Abstract

The invention relates to the technical field of sewage treatment, and discloses a sewage oxygen charging device. The device comprises an aeration tank body, a first rotation rod and a rotation sleeve. The rotation sleeve is provided with a rotation hole. The first rotation rod is placed in the rotation hole. The first rotation rod is connected with the rotation hole in dynamic sealing mode. The inner wall of the rotation hole is annularly provided with a revolving groove. A second gas transmission channel is communicated with the revolving groove. The rotation sleeve is provided with a fourth gas transmission channel which is communicated with the revolving groove. The fourth gas transmission channel is communicated with the side wall of the rotation sleeve. The rotation sleeve is provided with a second slide bearing face which is a partial spherical surface sharing the same center with the first slide bearing surface. The second slide bearing face is loaded on the first slide bearing face. When the first rotation rod makes a small angular swing in any direction relative to an output shaft, the rotation sleeve along with the first rotation rod make a displacement in a deflection cavity, thus effectively relieving the uneven stress between the rotation sleeve and the first rotation rod, and stabilizing the dynamic sealing between the rotation sleeve and the first rotation rod.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of sewage treatment, in particular to a sewage oxygenation device for domestic sewage treatment. [0003] 【Background technique】 [0004] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for drainage or reuse. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Domestic sewage treatment generally includes steps such as filtration, aeration, and sedimentation. Aeration refers to the process of forcibly transferring the oxygen in the air to the liquid. The purpose is to obtain dissolved oxygen in the sewage, so as to ensure that the microorganisms in the sewage have sufficient dissolved oxygen when decomposing organic matter. [0005] The patent application number 201610998821.8 discloses an aeration device ( figure 1 ), the first rotating rod in the a...
