Rotation aeration ejector and control system thereof

Abstract

The invention discloses a rotation aeration ejector and a control system thereof. The rotation aeration ejector comprises a base, a guide rod support and a guide rod; the base is fixedly mounted on afloor at the bottom of a pool through foundation bolts, the guide rod base is mounted on the base through foundation bolts, and the guide rod is welded to the guide rod base; a power pump is mounted at the right end of a self-coupling mechanism through connecting bolts, and a rotating tee joint is mounted at the top end of the self-coupling mechanism through connecting bolts; a steering driving mechanism is mounted at the top end of the rotating tee joint and fixed to the self-coupling mechanism through a fixing mechanism; the right end of a power pipeline is mounted on the rotating tee jointthrough flanges, and a mixed gas box is mounted at the outlet end of the power pipeline through flanges; and an aeration outlet pipe is mounted at the outlet end of the mixed gas box through flanges,a gas inlet pipeline communicates with the mixed gas box, and a filter net is mounted at the top end of the gas inlet pipeline. The rotation aeration ejector and the control system are scientific andreasonable in design, simple in structure and convenient to operate.

Description

Technical field: [0001] The invention relates to a rotary aeration injector and its control system, belonging to the technical field of aeration injectors. Background technique: [0002] In the prior art, when urban rainfall exceeds the water delivery capacity of urban drainage pipes, local deep water accumulation (inner waterlogging) will occur in the city. The rainwater with the transport capacity is stored in the rain and flood storage tank. After the rainfall is over, the rainwater in the rain and flood storage tank is discharged through the submersible sewage pump, thereby preventing urban waterlogging. [0003] Such storage tanks can also be installed at the entrance of the sewage treatment plant. After the peak water consumption, the inflow of the sewage treatment plant will exceed the design load. In order to avoid the direct discharge of excess sewage, the storage tank Storing overloaded sewage and leaving it for treatment when the inflow is low can effectively red...

AI Technical Summary

Problems solved by technology

[0004] Commonly used flushing equipment for rain and flood storage tanks includes flushing doors and flushing hydraulic dumps, etc. The flushing doors need to divide the storage pond into several flushing corridors for flushing separately, and the accumulated water can only be flushed once each time. It is limited to the shape of the pool. For example, when the pool is round or irregular, the above equipment cannot be used, or the design of the flushing corridor needs to avoid the support columns in the pool, otherwise the flushing effect will be greatly affected. If you stay For a long time, the silt is too thick and too thick to be washed away. Over time, in severe cases, the function of the rainwater storage tank may be lost and eventually abandoned; the flushing hydraulic tipping bucket and the flushing door are a one-time flushing process, and the flushing hydraulic tipping bucket is installed A certain height is required to generate sufficient scouring force, and the municipal pipe network often has insufficient height space, which greatly limits the scope and effect of hydraulic dumping

[0005] Manual dredging is labor-intensive and highly hazardous, and rain and flood storage tanks are mostly built underground, making manual dredging difficult

Long-term siltation will also lead to the death, decay and odor of organic matter, which will affect the environment, and at the same time, it will easily lead to the accumulation of harmful gases, posing a threat to the safety of dredging workers
