Description

Technical Field

[0001] The invention relates to the technical field of aeration equipment for water oxygenation technology, and is a new generation of high-efficiency novel ultra-micron bubble generating device, in particular to a floating ultra-micron bubble generating device. Background Art

[0002] The diameter of micron bubbles is generally below 50um. Compared with ordinary bubbles, this kind of tiny bubbles has many unique advantages, mainly manifested as: very large specific surface area, slow rising speed, and higher internal pressure and dissolution rate. The existence and development of micron bubbles in water are very different from ordinary bubbles. Ordinary bubbles rise from water to the gas-liquid interface and break, and the gas escapes and is lost. The ultra-micron bubbles generated by the new micron bubble system are very stable in aqueous solution. Existing reports have pointed out that when ultra-micron bubbles rise in aqueous solution, they gradually shrink to nanometers and finally disappear and dissolve into water, which can greatly increase the solubility of gas in water. Therefore, the use of ultra-micron bubbles can greatly increase the mass transfer rate of gas to liquid. The existing micron bubble generation equipment is large in size and can only be placed on the ground to work on the local water surface. The working range is narrow, resulting in poor applicability of the equipment. Summary of the invention

[0003] The purpose of the present invention is to provide a floating ultra-micron bubble generating device to solve the problems of high energy consumption, many components, large volume, narrow working range and serious "cavitation" phenomenon of existing ultra-micron bubble generating equipment.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A floating ultra-micron bubble generating device comprises a chassis, a buoyancy mechanism, a water distribution mechanism and a bubble generating mechanism, wherein the chassis is arranged on the upper part of a fixing frame of the buoyancy mechanism, the buoyancy mechanism comprises a floating barrel, a fixing frame, a fixing ring and a fixing group, the fixing frame is fixed to the upper part of the floating barrel in a tic-tac-toe pattern, and the chassis is fixedly arranged on the upper part of the fixing frame, a bubble generating mechanism is arranged inside the chassis, the bubble generating mechanism comprises a gas-liquid mixing tank, an impeller, a motor, a filter screen and a jet component, a main shaft with a plurality of impellers is arranged in a working chamber of the gas-liquid mixing tank, and the upper part of the main shaft is connected to the motor through a coupling; the water outlet of the gas-liquid mixing tank is connected to the water distribution mechanism through a pipeline, and the water distribution mechanism comprises an annular conduit, a water guide pipe and an ultra-micron nozzle.

[0006] Furthermore, the working chamber is a cylindrical cavity structure with a lower opening formed by a pull rod, and the impellers inside the working chamber are equidistantly arranged on the main shaft, and supporting guide vanes are arranged at the extension of the impellers, and the two impellers are connected to each other by a seal.

[0007] Furthermore, a water inlet is provided at the lower part of the working chamber, and a jet assembly is provided inside the water inlet; an air inlet end and a water inlet end are provided on the jet assembly, wherein the air inlet end is connected to the air inlet interface on the gas-liquid mixing tank through a hose.

[0008] Furthermore, a filter screen and a water outlet are respectively provided at the lower part and the side part of the gas-liquid mixing tank, and the filter screen is fixedly connected to the upper part of the gas-liquid mixing tank through a filter screen fixing rod; an air inlet and a pressure gauge port are provided at the upper part of the gas-liquid mixing tank.

[0009] Furthermore, the upper portion of the gas-liquid mixing tank is connected to the motor via a motor base, and a coupling connected to the main shaft is provided inside the motor base.

[0010] Furthermore, the float is a hollow floating ring structure, and an annular conduit connected to the water outlet is fixedly provided on the upper part of the float, and a connector and a water pipe connected to the connector are provided on the annular conduit.

[0011] Furthermore, the water pipe is a flexible pipe, and at least three water pipes are provided, and ultra-micron nozzles are provided at the ends of the water pipes.

[0012] Furthermore, the fixing ring is fixedly arranged on the outer wall of the floating barrel, and the outside of the fixing ring is connected to the fixing group through three fixing terminals and steel wire ropes. The fixing group includes a base, a fixing shaft, a telescopic rod, a fixing plate and an adjusting wheel. The fixing plate is movably connected to the base through the fixing shaft and the telescopic rod; a slide groove matching the telescopic rod is arranged on the upper part of the base, and a limiting pin is arranged on the slide groove; a plurality of fixing nails are arranged at the bottom of the base.

The water and the gas sucked by the jet device are stirred and sheared at high speed by the motor, and then enter the gas-liquid mixing tank for pressurized dissolution to reach high-pressure saturation, and the dissolved gas water is guided to the ultra-micron nozzle. The ultra-micron bubble nozzle suddenly dissipates energy and reduces pressure, which makes the micro-nano bubbles evenly and stably released in the water, forming "milky white" ultra-micron bubbles.

[0017] 2. An independent water distribution mechanism is set outside the floating barrel to mix the gas-liquid mixture through the annular conduit and evenly distribute it through the water pipe. The water pipe can be increased or decreased according to needs, which can increase the working area and facilitate the ultra-micron bubble to cover a larger range.

[0018] 3. A fixing ring and a fixing group connected to the fixing ring by a steel wire rope are arranged outside the floating barrel. The fixing group is arranged on the shore and is straightened and adjusted by three steel wire ropes. It can limit the entire equipment, prevent drifting during work, and improve the practicability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
