Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment aeration device. Background Art

[0002] In the prior art, an aeration tank is a structure for treating sewage using the activated sludge method. The aeration tank provides a certain sewage retention time to meet the oxygen required by aerobic microorganisms and the mixing conditions for sufficient contact between sewage and activated sludge. The aeration pipes in the current aeration tank are mainly laid at the bottom of the tank, and the aeration heads on the aeration pipes are easily blocked during use, affecting the aeration effect.

[0003] After searching, the Chinese patent application number 202322061635.X discloses a sewage treatment aeration device, including a treatment tank, an aeration branch pipe, an aeration pump, an aeration head and a cleaning assembly, the cleaning assembly including a hollow column, a hydraulic cylinder, a support frame, a filter screen and a support block, the aeration pump is arranged above the treatment tank, the aeration branch pipe is connected to the aeration pump and is located at the output end of the aeration pump, the aeration head is connected to the aeration branch pipe and is located on the outer side wall of the aeration branch pipe, the treatment tank has a water outlet and a water inlet, the water inlet is located on the left side of the treatment tank, and the water outlet is located on the right side of the treatment tank, the hollow column is fixedly connected to the treatment tank and is located at the bottom of the treatment tank, the hydraulic cylinder is fixedly connected to the hollow column and is located at the inner bottom of the hollow column, and the support block is fixedly connected to the treatment tank.

[0004] The above patent has the following shortcomings: the device uses a hydraulic cylinder to move the filter upward, and the filter slides in the treatment tank at this time. When the filter moves to the top of the treatment tank, the non-degradable impurities in the treatment tank can be cleaned to avoid clogging the filter, thereby effectively improving the efficiency of sewage treatment; however, in actual use, the aeration branch pipe and the aeration head are both at the top of the filter. Combined with the drawings in its specification, the top of the hydraulic cylinder is directly connected to the filter to drive the filter to rise and fall, but there is a lack of isolation between the filter and the telescopic end of the hydraulic cylinder. After the sewage enters the treatment tank, the sealing ring can only seal the connection between the hollow column and the filter, but cannot seal the top of the hollow column. The sewage will enter the inside of the hollow column and corrode the hydraulic cylinder, affecting its normal operation. Utility Model Content
