Laminar flow exchange type micro-nano oxygen-increasing water-flowing machine

Abstract

The invention discloses a laminar flow exchange type micro-nano oxygen-increasing water-flowing machine. The machine includes a circulating water-flowing device and a micro-nano aeration device. The circulating water-flowing device includes a top cover, a driving device and an impeller with a plurality of blades in sequence from top to bottom. The micro-nano aeration device is connected below thecirculating water-flowing device, and includes a flow divider, at least a dissolved gas tank and a double-suction pump in sequence from top to bottom; the end of a water inlet of the double-suction pump is provided with an air inlet for communicating with the external atmosphere; a water inlet of the flow divider is connected with a water outlet of the double-suction pump; a plurality of water outlets are arranged at the top of the flow divider; the water outlet of each flow divider is connected with the dissolved gas tank through a water inlet of the dissolved gas tank; a water inlet of the dissolved gas tank and the interior of the dissolved gas tank are provided with at least a group of flow-disturbing blades; and a water outlet position at the bottom of the dissolved gas tank is provided with a Venturi tube, and a liquid in the dissolved gas tank is discharged into a water body through the Venturi tube. The machine of the invention can rapidly realize three-dimensional circulationconvection of the water body, and generate uniform high-density micro-nano bubbles, and promote dissolution of oxygen.

Description

technical field [0001] The invention relates to a laminar flow exchange type oxygen-enhancing water dispenser, in particular to a laminar flow exchange type micro-nano oxygen-enhancing water dispenser. Background technique [0002] Water is the source of life and an important and indispensable substance for the survival of human beings and all living things. In recent years, with the continuous deepening of my country's urbanization and industrialization process, while the economic level is developing rapidly, the limited fresh water resources have been affected by human activities. . It has posed a serious threat to people's production and life, and has become one of the problems that need to be solved urgently. [0003] Aeration and re-oxygenation of water bodies is an important technical means of water environment restoration developed in recent years. It uses the method of injecting gas into water bodies to promote the exchange of water bodies up and down, and breaks th...

[0004] CN202116385U discloses a kind of oxygen-increasing circulation running water machine composed of a circulation machine and an aeration machine, which mainly generates ultra-fine air bubbles through high-speed gyrations, and then diffuses into the water after being mixed by a stirring device formed by a motor combined with gears and blades. The fine bubbles generated by the first-stage gyration have the disadvantage of low gas dissolution rate, and the deceleration stirring device composed of motor and gear consumes a lot of energy, has a short life, and has high long-term maintenance costs

CN106315882A discloses a laminar exchange type oxygen-increasing living water machine composed of a water collection funnel, a diversion tube and a push-flow pump. The surface water is sucked to the bottom by the push-flow pump installed at the bottom, thereby achieving the purpose of increasing oxygen. However, this method has a limited oxygenation efficiency

CN206213034U discloses a kind of oxygen-increasing live water machine that is made up of motor, impeller and wheel disc, this kind method drives the impeller to rotate to produce ripple in water to water body oxygenation by motor, but this kind method can not oxygenate deep water body, increase The effect of oxygen is not obvious

CN106365333A discloses a fully automatic water treatment device driven by solar energy. The three-dimensional circulation of the water body can be realized under the water lifting action of the aqueduct impeller of the device, but the device is driven by solar energy, so the power is low, and it takes time to promote the water body circulation. Longer, and the reliability of solar power supply is greatly affected by the weather

[0005] CN102219315A discloses a micro-nano oxygenation device composed of a water pump, an accumulator and a wide-slit nozzle. The device cuts the gas-liquid mixture through the blades of the water pump and the nozzle to form fine bubbles, but the gas that enters the accumulator The liquid mixture is only cut by the impeller blades, and the bubbles are not uniform enough, so the efficiency of dissolved oxygen is limited

CN102001719B discloses a device for generating micro-nano bubbles through a microporous device, but the uniformity of the bubbles generated by the microporous device is insufficient, and there are shortcomings such as high manufacturing and processing precision and easy blockage

CN203212385U discloses a swirl type micro-nano aerator driven by solar energy, the device utilizes high-speed swirling water flow to drive air mixing, but the method has a low efficiency of dissolving air and cannot form a supersaturated solution

CN205575786U discloses a jet-type micro-nano aeration system, which has the disadvantages of complex flow channel design and cumbersome installation procedures.

CN204981362U discloses a micro-nano aeration and oxygenation device made up of a self-priming pump, a gas-liquid mixed fluid pipe and a micro-nano generator. The device decompresses and releases the gas-water mixed liquid at a high speed to form micro-nano bubbles. The gas port is set in the gas-liquid mixer, resulting in a low pressure in the mixer and limited dissolved gas

CN206407964U discloses a kind of suspension type micro-nano aeration device that is made up of submersible pump and injector, forms negative pressure in injector and sucks in air during this device work, gas-liquid mixed liquid is ejected to form micro-bubble afterwards, this kind of method also There is a deficiency of low dissolved gas
