This invention provides a multi-stage, multi-angle, rapid diffusion oxygen dissolving three-dimensional non-clogging microbubble aerator. An air inlet pipe and an air pipe are sequentially connected along the air inlet direction. A rapid microbubble cutting and diffusion oxygen dissolving unit is fitted outside the air inlet pipe. An inner cylinder and an outer cylinder are sequentially fitted outside the air pipe from the inside to the outside. The inner cylinder has a first inner cylinder section, a second inner cylinder section, and a third inner cylinder section sequentially along the air inlet direction. A medium-sized bubble cutting and diffusion oxygen dissolving unit is installed on the outer wall of the first inner cylinder section, a large bubble cutting and diffusion oxygen dissolving unit is installed on the outer wall of the second inner cylinder section, and an air guiding unit is installed on the outer wall of the third inner cylinder section. An air diffuser unit is installed at the air outlet of the air pipe. This multi-stage, multi-angle, rapid diffusion oxygen dissolving three-dimensional non-clogging microbubble aerator effectively cuts air into microbubbles, effectively solving the problems of clogging and short lifespan of traditional aerators after long-term use, and is suitable for aerobic aeration treatment.

The utility model discloses an aeration flow guide device applied to an ecological filter, which relates to the technical field of aeration flow guide devices and comprises a support frame, a flow guide part is mounted on the surface of the support frame, an aeration part is mounted on one side of the support frame, a filter part is mounted on the surface of the support frame, the aeration part comprises a transmission pipe, and the transmission pipe is fixedly connected to one side of the support frame. One end of the transmission pipe is provided with an air pump and is fixedly connected with a flow guide pipe. Water in the ecological filter tank is conveyed into the partition cylinder through the first submersible pump, then the water is filtered through the first filter cylinder and the second filter cylinder, the water in the ecological filter tank is pumped through the second submersible pump, the water is conveyed into the filter assembly through the output pipe, and the filtered water is conveyed to the water outlet pipe. The second submersible pump conveys water to a spray head, and the filtered water is sprayed out, so that the water in the ecological filter tank is filtered, meanwhile, the contact area between the water body and air can be increased, and the dissolved oxygen content of the water body is increased.

This invention belongs to the field of aerobic biochemical technology, specifically relating to a liquid-gas jet injector, including an air inlet pipe, a liquid inlet pipe, an air intake tank, a jet nozzle, a throat, a guide tube, and a mixer. A first channel is provided between the outlet of the nozzle and the first jet port of the air intake tank, allowing air to be drawn into the first jet port through the first channel. The throat is connected to the first jet port. A second channel is provided between the outlet of the throat and the guide tube to facilitate the intake of liquid flow to form a second gas-liquid mixture. The throat is used for the first gas-liquid mixing and transport, and the mixer is used for the mixing and transport of the second gas-liquid mixture. The gas-liquid mixture at the outlet of the mixer comes into contact with the liquid in the liquid pool, forming a third oxygen transfer. This solution achieves three-stage oxygen mass transfer between gas and liquid, overcoming the limitation of the optimal 1:1 mass transfer ratio of air to liquid in the throat; it ensures thorough mixing of gas and liquid, avoiding the drawbacks of localized high dissolved oxygen; and it improves the oxygen transfer efficiency between gas and liquid.
