Description

Technical Field

[0022] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0023] A micro-nano bubble coagulation-aided microfiltration machine includes a concrete tank body 1, wherein the concrete tank body 1 includes a submersible micro-nano dissolved air tank body 101 located at the front and a microfiltration machine tank body 102 located at the rear, and the submersible micro-nano dissolved air tank body 101 and the microfiltration machine tank body 102 are interconnected; a water inlet 103 is provided at the front of the submersible micro-nano dissolved air tank body 101, and a water outlet 104 is provided at the rear of the microfiltration machine tank body 102; a micro-nano coagulation-aided control box 105 is also installed on the concrete tank body 1.

[0024] The submersible micro-nano dissolved air pool 101 is provided with a submersible micro-nano dissolved air device 2 , which includes a micro-nano release screen 201 .

[0025] The working principle of the submersible micro-nano dissolved air device 2: The air pump's suction port draws in air using negative pressure, eliminating the need for an air compressor or atmospheric ejector. The high-speed rotating pump impeller mixes and stirs the liquid and gas, eliminating the need for an agitator or mixer. The pressurized mixing within the pump ensures thorough dissolution of the gas and liquid, achieving a dissolution efficiency of 80-100%. This eliminates the need for large pressurized air dissolving tanks or expensive reaction towers to produce highly dissolved liquids. The gas-liquid ratio is approximately 1:9 (with an air intake of 8-10%), and cascading units can increase intake capacity.

[0026] A microfilter 3 is installed in the microfilter pool body 102, and the microfilter 3 includes a microfilter steel frame 301, a splash guard 302 is installed inside the microfilter steel frame 301, and a screen plate 303 is installed on the splash guard 302; a slag bucket 308 is provided inside the screen plate 303, and a slag bucket support 309 is provided outside the screen plate 303; the microfilter 3 includes a micro-nano bypass flushing port 304, the front end of the micro-nano bypass flushing port 304 is connected to the micro-nano release screen 201, and the rear end is connected to the dissolved air flushing nozzle 305; the microfilter 3 includes a drum drive motor 306 and a drum gear box 307.

[0027] Working principle of microfiltration machine 3:

[0028] The microfilter is a rotary drum-type screen filter. Pool water is pumped out axially into the drum via a water pump and flows radially out through the screen. Impurities in the water (such as fine suspended matter from fish feces, etc.) are trapped on the inner surface of the drum's screen. When the amount of impurities trapped on the screen reaches a certain level, the device automatically starts, and the impurities are carried to the upper part of the drum. Pressure-washing water then flushes them back into the slag trough and out. Once the impurities in the drum have been rinsed clean, the device automatically stops and waits for the next cycle.

[0029] The addition of micro-nano bubble technology utilizes the tiny bubbles present in liquids. Bubbles with a diameter of less than 100μm are called microbubbles, and those with a diameter of less than 100nm are called nanobubbles. Micro-nano bubbles are bubbles with diameters ranging from tens of microns to hundreds of nanometers. These bubbles, intermediate between microbubbles and nanobubbles, possess physical and chemical properties not possessed by conventional bubbles, enabling more efficient separation of impurities from water.

[0030] The above detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention but merely represents selected embodiments of the present invention.
