The first grinding device ( 46 ) connects to the sidewall of the pressure equalizer ( 41 ), communicates with the inner chamber of the pressure equalizer ( 41 ) and has at least one ground fluid outlet ( 4611 a , 4611 b ). The first grinding device ( 46 ) has a hollow barrel ( 461 ), a cover ( 462 ), multiple grinding sheets ( 463 ), a fastening shaft ( 464 ) and a pressure regulating shaft ( 465 ).
With further reference to FIGS. 4 and 5 , the barrel ( 461 ) has an open proximal end ( 4612 ), an open distal end ( 4613 ), a sidewall, an inner chamber ( 4615 ), two ground fluid outlets ( 4611 a , 4611 b ) and an annular protrusion ( 4616 ).

The ground fluid outlets ( 4611 a , 4611 b ) connect to the sidewall of the barrel ( 461 ) and communicate with the inner chamber ( 4615 ) of the barrel ( 461 ). The annular protrusion ( 4616 ) protrudes radially inwards from the inner surface of the sidewall and is formed in the inner chamber ( 4615 ) near the proximal end ( 4612 ) to form an inlet channel ( 4614 ). The inlet channel ( 4614 ) communicates with the pressure equalizer ( 41 ).
The cover ( 462 ) is mounted in and seals the outlet opening of the distal end ( 4613 ) of the barrel ( 461 ) and has a central hole ( 4621 ). The central hole ( 4621 ) is defined through the cover ( 462 ) and communicates with the inner chamber ( 4615 ).
With further reference to FIG. 6 to FIG. 8 , the grinding sheets ( 463 ) are mounted in the inner chamber ( 4615 ) and an interval is formed between the grinding sheets ( 463 ) and the inner surface of the sidewall of the barrel ( 461 ). Each grinding sheet ( 463 ) has a proximal surface, a distal surface, an axle hole ( 4631 ) and multiple diversion holes ( 4632 , 4632 a , 4632 b ). The axle hole ( 4631 ) is defined centrally through the grinding sheet ( 463 ) and has a first axis. The diversion holes ( 4632 , 4632 a , 4632 b ) are formed around the axle hole ( 4631 ) at intervals and each diversion hole ( 4632 , 4632 a , 4632 b ) has a second axis and a slanted degree. The slanted degree is between a the second axis of the diversion hole ( 4632 , 4632 a , 4632 b ) and the first axis of the axle hole ( 4631 ) and is in a range from 0° to 60°. In one aspect, the diversion hole ( 4632 , 4632 a , 4632 b ) may be parallel with the horizontal plane (the slanted degree is)0° as shown in FIG. 4 . In another aspect, the grinding sheet ( 463 ) may be a clockwise grinding sheet ( 463 a ) that is slanted toward the axle hole ( 4631 ) from the proximal surface of the grinding sheet ( 463 ) to the distal surface of the grinding sheet ( 463 ) as shown in FIG. 7 . In yet another aspect, the grinding sheet ( 4632 , 4632 a , 4632 b ) may be a counterclockwise grinding sheet ( 463 b ) that is slanted toward the sidewall of the barrel ( 461 ) from the proximal surface of the grinding sheet ( 463 ) to the distal surface of the grinding sheet ( 463 ) as shown in FIG. 8 . The grinding sheet ( 463 ) with different diversion hole ( 4632 , 4632 a , 4632 b ) can be arranged according to desired effect. When the mixed fluid passes the grinding sheets ( 463 ), the grinding sheets ( 463 ) rotate relatively to grind and disperse the mixed fluid to obtain a ground fluid. The ground fluid is released into the inner chamber ( 4615 ).
The fastening shaft ( 464 ) is T shaped and has a shaft body ( 4641 ) and a first cushion ( 4642 ). The shaft body ( 4641 ) is mounted in the axle holes ( 4631 ) of the grinding sheets ( 463 ) and has a proximal end and a distal end. The distal end of the shaft body ( 4641 ) faces the cover ( 462 ). The first cushion ( 4642 ) is mounted on the distal end of the shaft body ( 4641 ) and has a proximal surface and a distal surface. The proximal surface abuts the grinding sheet ( 463 ) that is closest to the cover and allows all grinding sheets ( 463 ) to be mounted between the proximal surface of the first cushion ( 4642 ) and the annular protrusion ( 4616 ).
With further reference to FIG. 9 , the pressure regulating shaft ( 465 ) is T shaped and has a shaft body ( 4651 ) and a second cushion ( 4652 ).
The shaft body ( 4651 ) of the pressure regulating shaft ( 465 ) may be threaded, protrudes in the central hole ( 4621 ) of the cover ( 462 ) and has a proximal end, a distal end, at lest one rubber seal ring ( 466 ), a positioning nut ( 467 ) and a fastening nut ( 468 ). The proximal end of the shaft body ( 4651 ) faces the first cushion ( 4642 ) of the fastening shaft ( 464 ) and is mounted in the barrel ( 461 ). The distal end of the shaft body ( 4651 ) is mounted out of the barrel ( 461 ) and has a screw recess ( 4653 ). The screw recess ( 4653 ) is formed in the distal end of the shaft body ( 4651 ) and allows a screwdriver to protrude in the screw recess ( 4653 ) and rotate and adjust the pressure regulating shaft ( 465 ). The rubber seal ring ( 466 ) is mounted in the central hole ( 4621 ) of the cover ( 462 ) and around the shaft body ( 4651 ). The positioning nut ( 467 ) is mounted around the shaft body ( 4651 ) and out of the barrel ( 461 ) and abuts the cover ( 462 ) to position the pressure regulating shaft ( 465 ). The fastening nut ( 468 ) is mounted around the shaft body ( 4651 ) and selectively abuts the positioning nut ( 467 ). After the positioning nut ( 467 ) is adjusted, the fastening nut ( 468 ) tightly abuts the positioning nut ( 467 ) and the friction between the positioning and fastening nuts ( 467 , 468 ) prevents the positioning nut ( 467 ) from inadvertently moving on the shaft body ( 4651 ) to fasten the pressure regulating shaft ( 465 ).
The second cushion ( 4652 ) is mounted on the proximal end of the shaft body ( 4651 ) and has a proximal surface and a distal surface. The proximal surface abuts the distal surface of the second cushion ( 4642 ) and applies an applicable pressure to press the grinding sheets ( 463 ). The distal surface connects to the proximal end of the shaft body of the pressure regulating shaft ( 465 ).
The second grinding device ( 45 ) connects to the sidewall of the pressure equalizer ( 41 ) opposite to the first grinding device ( 46 ), communicates with the inner chamber of the pressure equalizer ( 41 ) and has at least one ground fluid outlet ( 4511 ) and a backflow pipe ( 451 ). The backflow pipe ( 451 ) connects to and communicates with the ground fluid outlet ( 4511 ) and the raw material feeder ( 10 ) to connect the second grinding device ( 45 ) with the raw material feeder ( 10 ) and the backflow pipe ( 451 ) has a solenoid valve ( 452 ). The second grinding device ( 45 ) has a same structure of the first grinding device ( 46 ).
The subsequent treatment plant ( 50 ) connects to the first grinding device ( 46 ) and has a bottle filling machine ( 51 ), a filling pipe ( 52 ), a relief tank ( 53 ) and a connecting pipe ( 54 ). The bottle filling machine ( 51 ) is used to bottling the ground fluid. The filling pipe ( 52 ) connects to the bottle filling machine ( 51 ) to the ground fluid outlet ( 4611 a , 4611 b ) of the first grinding device ( 46 ) and has a solenoid valve ( 521 ). The relief tank ( 53 ) has a bottom, an inner chamber and a ground fluid outlet ( 53 ). The inner chamber of the relief tank ( 53 ) receives the ground fluid. The ground fluid outlet ( 53 ) connects to the bottom of the relief tank ( 53 ) and communicates with the inner chamber of the relief tank ( 53 ). The connecting pipe ( 54 ) connects the relief tank ( 53 ) to the ground fluid outlet ( 4611 a , 4611 b ) of the first grinding device ( 46 ) and has a solenoid valve ( 541 ).
When the nano grinding and dispersing assembly of the present invention is used, a liquid raw material is conveyed into the inner chamber of the raw material feeder ( 10 ) via the feeding pipe ( 11 ). The liquid raw material flows in the delivering pipe ( 12 ) and is pumped by the pump ( 13 ) to flow in the pressurized feeding pipe ( 42 ). Then, the liquid raw material flows into the pressure equalizer ( 41 ) via the joint ( 411 ) and is ground and dispersed by the second grinding device ( 45 ). Because the liquid raw material may contain tiny organic matter, the liquid raw material is homogeneous and uniform after passing through the second grinding device ( 45 ). After being ground, the liquid raw material flows back to the inner chamber of the raw material feeder ( 10 ) via the backflow pipe ( 451 ) to circulate the liquid raw material.
After the liquid raw material is homogeneous, liquid, solid or gas applied from the liquid supply unit ( 20 ) or the gas supply unit ( 30 ) are mixed with the liquid raw material to form a mixed fluid. The mixed fluid flows into the pressure equalizer ( 41 ) via the pressurized feeding pipe ( 42 ) and the pressurized feeding pipe ( 42 ). If the mixed fluid contains surplus gas, the surplus gas can be released from the gas outlet ( 431 ) of the gas-liquid separator ( 43 ). Then the mixed fluid flows into the first grinding device ( 46 ) from the inlet channel ( 4614 ). The pressure regulating shaft ( 465 ) is adjusted according to the pressure gage ( 44 ) to apply an applicable pressure to press the grinding sheets ( 463 ). The mixed fluid passes the grinding sheets ( 463 ) to drive the grinding sheets ( 463 ) to rotate relatively, so the mixed fluid is ground and dispersed to obtain a ground fluid. The ground fluid is released into the inner chamber ( 4615 ) of the barrel ( 461 ) and then is discharged from the first grinding device ( 46 ) through the ground fluid outlet ( 4611 a , 4611 b ) and via the filling pipe ( 52 ) or the connecting pipe ( 54 ) to the bottle filling machine ( 51 ) or the relief tank ( 53 ).
Raw material in the raw material feeder ( 10 ) of the present invention is liquid and the mixed fluid may be gas-liquid system, solid-liquid system or liquid-liquid system.
In the gas-liquid system, gas is supplied from the gas supply unit ( 30 ) and includes, but not limited to air, nitrogen, oxygen, ozone, hydrogen, carbon monoxide, carbon dioxide, sulfur dioxide, nitric dioxide or the like. In one aspect, a suitable amount of air and coagulants are mixed into wastewater. After wastewater with air passes through the first grinding device ( 46 ) of the pressure equalized assembly ( 40 ), the wastewater is full of nano-scaled air bubbles. Impurities such as pollutants, suspended solid or the like in the wastewater are removed by flotation. In other aspect, ozone is mixed in tap-water, nitrogen is mixed in beverages or alcohols for preserving beverages or alcohols, oxygen is mixed in mineral water for increasing oxygen concentration, oxygen or ozone is mixed in water in a bath, sulfur dioxide or ozone is mixed in industrial bleach, oxygen is mixed in fish-raising water or the like.
In the solid-liquid system, solid comprises solid powders that are mixed in liquid and are supplied from the liquid supply unit ( 20 ). After solid-liquid mixed fluid passes through the first grinding device ( 46 ), the solid powders are ground to nano-scaled powders. After dehydration, dried nano-scaled powders are obtained. In one aspect, the solid includes algae, pollen or the like. Cell walls of algae, pollen or the like are broken and algae, pollen or the like are ground into nano-scaled powders after pass through the first grinding device ( 46 ). In another aspect, the solid includes ceramic material, which can be ground into nano-scaled powers. In yet another aspect, the solid includes organic additives in cosmetics. The organic additives are homogenous and fined in cosmetics after passing the pressure equalized assembly ( 40 ).
In the liquid-liquid system, two liquids are respectively supplied from the raw material feeder ( 10 ) and the liquid supply unit ( 20 ). Two liquids can be mixed homogeneously after passing through the first grinding device ( 46 ) of the pressure equalized assembly ( 40 ). For example, without limitation, a suitable amount of water or organic solvent in mixed with organic oil (miscible water and oil) for being used conveniently, water is mixed with fuel oil for increasing combustion efficiency and lowering air pollution, ethanol is mixed with high-performance fuel, high-performance oil is mixed in low-performance ethanol or the like.
