The utility model relates to aquatic product breeding equipment technical field especially is used in aquatic product breeding oxygenation device, including oxygen -enriching machine body, the oxygen -enriching machine body outside is equipped with the floating mechanism for making oxygen -enriching machine body float and is used for the filter mechanism of filtering, the filter mechanism includes the mounting bracket, the inside of mounting bracket is provided with the sliding slot, the inside of sliding slot is provided with the filter plate, the middle part end face of mounting bracket evenly is provided with the connecting groove, the inside of sliding slot evenly is provided with the locating groove, the inside of mounting bracket is provided with the limit component, the oxygen -enriching machine body outside is equipped with the connecting component for the oxygen -enriching machine body and the floating mechanism connection. In the utility model, through the cooperation of filter mechanism and connecting component, the filter plate state can be adjusted flexibly, the setting of connecting component, only need to press the pressing plate to realize the quick disassembly and installation of oxygen -enriching machine body and floating mechanism, and the oxygen -enriching machine body cleaning maintenance and filter plate cleaning are convenient.

The utility model provides a speaking valve which comprises a frame body and a valve, the frame body comprises a channel, a baffle located at one end of the channel and a connector located at the other end of the channel, the valve is located on the side, close to the connector, of the baffle, the middle portion of the valve is fixedly connected with the baffle, and the baffle is provided with a plurality of air inlet holes. The multiple air inlet holes are arranged at intervals in the circumferential direction of the baffle and are arranged into at least two circles, and the total area of all the air inlet holes in the radial outer circle is larger than that of all the air inlet holes in the radial inner circle. According to the utility model, the middle part of the valve is fixed on the baffle plate, and the area of the air inlet holes on the radial outer side is larger than that of the air inlet holes on the radial inner side, so that a patient only needs to apply a small suction force, and then most of air flows into the shell through the air inlet holes on the radial outer side; the edge of the valve is quickly warped and deformed, air entering is accelerated, the inspiration pressure of a patient is relieved, and the disease of the patient can be recovered as soon as possible.

The utility model discloses inverted rotary ceramic membrane equipment. The inverted rotary ceramic membrane equipment comprises an inverted rotary ceramic membrane unit, a material conveying unit, a water producing unit, a backwashing water replenishing unit and a control unit, through the design of the spraying system, the defects of low water production efficiency, high energy consumption and frequent backwashing in the prior art are effectively improved, longer water production time, lower operation cost and more simplified process flow are realized, and an efficient, energy-saving, economical and practical solution is provided for the field of fermentation liquor separation and purification.
