The utility model relates to water body oxygenation technical field especially, more particularly to a fan circulating water oxygenation equipment. Its technical scheme includes: pedestal, suction chamber and suction pipe, be equipped with the nozzle on the pedestal, be equipped with the suction chamber on the nozzle, the other end of suction chamber is equipped with the mixing chamber, the other end of mixing chamber is equipped with the diffusion chamber, the mixing chamber, nozzle, suction chamber and diffusion chamber constitute the jet structure, jet structure is used for gas water mixture, increases water body oxygen content, the bottom end suction inlet of suction chamber is equipped with suction pipe, the bottom end of suction pipe is equipped with the impurity removal structure, and the impurity removal structure is used for removing the impurity that suction pipe orifice filters. The utility model discloses through the jet structure and carries out the water body oxygenation circulation of lasting, has improved water body dissolved oxygen content, the impurity that automatic cleaning filter plate surface adheres, ensures the filtering effect of filter plate sustained and stable, avoids the equipment performance decline caused by the impurity blockage or accumulation.

The utility model discloses a coal mine ventilation device relates to mine ventilation technical field, including the front and rear arrangement's air intake head and air outlet head, and the air intake head and air outlet head are connected with the air distribution pipe, and the air intake head is connected coal mine downhole pressure system through the pipeline, provides high pressure air, and the air outlet head is connected return air lane through the pipeline, and exhausts mixed gas, and the air distribution pipe includes suction chamber, throat and diffusion chamber, and suction chamber, throat and diffusion chamber constitute venturi effect, and the entrance position of suction chamber is provided with the nozzle, and the nozzle is opposite the throat jet, and the diffusion chamber includes gradually expanding section and export section who sets gradually from front to back, and the cross section area of gradually expanding section is increasing along the flow direction, and extends to export section, and the top of suction chamber is provided with the air inlet, and the air inlet communicates outside and suction chamber. Through high pressure jet flow produces the negative pressure, and the initiative suction blind lane dirty air, need not mechanical rotating part, fundamentally eliminates the explosion risk, improves ventilation efficiency and reduces energy consumption simultaneously.
