Description

System of continuous mass producing nano particle with classification

The present invention relates to a system for continuously producing nanoparticles in large quantities and precisely sorting and sorting them by size, and more particularly, to nanometer (nm) sizes of micrometer-sized raw materials by mechanical multi-stage impact. The present invention relates to a mass production and sorting system for nanoparticles, which is pulverized into nanoparticles, collected, cooled, and then subjected to a strong physical multi-stage impact to be converted into fine nanoparticles and automatically sorted by a certain size.

The production technology of nanostructured powder materials (nanoparticles) is a foundation technology applied to new technology fields including nano devices and is recognized as important.

Nanoparticles generally refer to a size of less than 100 nanometers (nm) in diameter, and the surface area is increased due to the characteristics of the small nanoparticles, and thus, specific electrical, electronic, mechanical, and catalytic properties that cannot be obtained with conventional materials In addition, by using these characteristics, ultra-high strength parts, magnetic parts, thermoelectric sensors, filters, catalysts, and the like, are being applied in all fields of the industry as next-generation functional materials.

On the other hand, with the development of high-tech industry, high performance and miniaturization of parts and systems are required, and micron or sub-micron size particles are currently used, and nano particles have limited limitations of existing technologies for high performance and miniaturization of parts and systems. Overcoming, new performance can emerge, making it an essential material for future technology and advanced product development.

In other words, nanoparticles are nanoscale particles, which are completely different from bulk materials due to their relatively large surface area and quantum confinement effect, in which the energy required for electron transfer varies with the size of the material. , Electrical and magnetic properties, and because of these properties, much attention has been paid to the applicability in the field of catalysts, electro-magnetics, optics, medical.

Nanoparticles (tubes) In particular, carbon nanoparticles were discovered in the early 1990s, and since then intensive research has been conducted on nanoparticles for use in various industrial applications. In fact, carbon nanostructures can be used for artificial muscles, biosensors, composite materials, conductive plastics, flat-panel displays, microelectronic devices, super-rigid fibers, electron field emission, gas accumulation, technical textiles, and flame retardants. Many fields, such as protection and anti-static, show very unusual and useful properties mechanically, electrically, magnetically, optically and thermally.

Various methods have been developed, including laser ablation, electrical arc discharge, and catalytic carbon deposition (CCVD) of hydrocarbons using metallic catalysts as various production methods for controlling the properties of nanoparticles. In particular, the CCVD method provides high yield and good quality carbon nanoparticles (tubes) and simplifies the industrial fabrication process compared to other methods. Most research using CCVD technology is currently focused on developing new catalysts to control the type (single, double and multiwall), diameter, length and purity of carbon nanotubes. The structural, physical and chemical properties of carbon nanotubes (particles) are related to electrical conduction capacity, mechanical strength, thermal, optical and magnetic properties.

Carbon nanotubes are hexagonal annular because three carbon atoms are bonded to one carbon atom adjacently, and the hexagonal annular shape is formed in a cylindrical or tubular shape by curled planes. Such carbon nanotubes have a property of exhibiting metallic conductivity or semiconductor conductivity according to their structure, and are widely attracted as new materials of the future because they can be widely applied in various technical fields. For example, carbon nanotubes are applicable to electrodes of electrochemical storage devices such as secondary cells, fuel cells or supercapacitors, electromagnetic shielding, field emission displays or gas sensors.

Conventional technology for producing such nanoparticles is the 'electrostatic dispersion and classifier of nanoparticle production system' according to Korean Patent Registration No. 10-0586184 (2006. 05. 26.).

The electrostatic dispersing device 60 is installed in the stirrer 10, the pump 20, the pulverizer / disperser 30, the classifier 40, the circulation circuit 50, and adds electrostatic force to the material, thereby dispersing the material. Be sure to

Therefore, the system configuration is relatively complicated, the productivity is low, the maintenance of the system and the production cost of the nanoparticles. This still takes a lot of trouble.

Therefore, in the production of nanoparticles, it is necessary to develop a nanoparticle mass production technology that has a relatively simple system configuration and a production process, a relatively low production cost of nanoparticles, and a high productivity and a constant particle size.

The added water is mixed with the raw materials during the grinding process.

In the following description, both the raw materials added and the raw materials in the process of processing will be described as nanoparticles, and if necessary, they will be divided and described.

The grinding motor unit 1130 is fixed to the upper outer center portion of the body portion 1110 and rotates the rotating shaft in the 1200 RPM range by the corresponding control signal applied from the central control unit 6000. It is very natural that it can be rotated to any value selected in the range of 1000 to 1500 RPM, if necessary, it is composed of a step motor easy to control. Rotational force is described as having sufficient power to drive the system.

The cylindrical portion 1140 is connected to the rotary shaft of the grinding motor unit 1130 and has a cylindrical shape with an open lower portion as a whole, and is installed in the cylindrical space portion 1111 in a rotational state.

Rotating cutter portion 1150 is a plurality of repeating cutters on the outer circumferential surface of the cylindrical portion 1140 are repeatedly arranged in a plurality of uniform intervals and widths up, down, left and right on the same line.

The rotary cutter unit 1150 may be configured with one or more protrusions on the side wall or the upper surface in order to smoothly induce the flow of the pulverized nanoparticles. At this time, the projections are provided with a configuration of the function and shape of airflow formation to flow the fluid consisting of nanoparticles or nanoparticles containing a liquid downward. Such a configuration is generally known.

The fixed cutter unit 1160 has a plurality of cutters for grinding at least two on the inner circumferential surface of the cylindrical space portion 1111 are repeatedly arranged (arranged) at uniform intervals and widths up, down, left and right, but do not collide with the rotary cutter unit 1150. It is installed spaced up and down while maintaining the specified interval. The interval spaced left and right on the same horizontal line may be repeatedly configured to be spaced apart from the corresponding value in the horizontal width formed by the unit fixing cutter unit 1160.

The vertical gap formed by the fixed cutter unit 1160 and the rotary cutter unit 1150 in the adjacent state for pulverization forms an vertical gap by any one value selected from a range of 100 to 500 micrometers (um), and 250 It is relatively desirable to configure such that the spacing of the micrometers is maintained. It is natural that this spacing is applied differently depending on the kind of material to be ground. The fixed cutter unit 1160 is configured to adjust such a gap by the adjustment.

The rotating cutter unit 1150 and the fixed cutter unit 1160 may form an angle, such as an acute angle, a right angle, or an obtuse angle, for crushing, to crush the objects located between them while cutting each other by cutting or the like. Is enough. Forming a right angle is relatively preferable in terms of maintenance and lifespan. It is natural that such an angle is included in the configuration to allow the flow of the nanoparticle fluid to flow downward.

In one embodiment, when the rotary cutter unit 1150 is located above the fixed cutter unit 1160 to perform a grinding function, the blade of the rotary cutter unit 1150 forms an obtuse angle and the blade of the fixed cutter unit 1160 In the case of forming an acute angle or a right angle, the fluid may form an air flow flowing downward.

The fixed cylindrical portion 1180 is fixedly installed at the central position of the cylindrical space portion 1111, the upper end is sealed and the lower end has an open cylindrical shape and partially penetrates along the upper outer circumferential surface to block the passage of foreign matter ( 1181 is provided.

The screen 1181 is described as being configured to filter the pulverized nanoparticles to prevent objects larger than 500 micrometers from passing through and to be separated and maintained.

The pipe 1190 is a pipeline for transmitting the nanoparticles discharged from the first crusher 1100 to flow into the inlet 1120 of the second crusher 1200.

In addition, it is very natural that the crushing unit 1000 may further include a third crushing unit, a fourth crushing unit, and an n-th pulverizing unit by necessity such as securing very fine nanoparticles or nanoparticles having a uniform size. You can also reduce the number.

The collecting unit 2000 controls the humidity by introducing the nanoparticles from the crushing unit 1000 and filters only nanoparticles having a prescribed size or less, and includes a compressor unit 2100, a drying unit 2200, and a filtering unit 2300. It is a constitution.

The compressor unit 2100 collects and concentrates the nanoparticles that are introduced and scattered into the second grinding unit 1200 of the grinding unit 1000. Since such a configuration is relatively general, a detailed description thereof will be omitted.

The drying unit 2200 is configured to stabilize the nanoparticles introduced from the compressor unit 2100 at a predetermined temperature and a relatively low humidity, and thus, detailed description thereof will be omitted. The specified temperature is room temperature, preferably about 25 degrees Celsius, and the humidity can be controlled to be any value selected from the range of 3% to 12% as needed. The preferred humidity here is to keep 4% constant.

The filter unit 2300 will be described as a configuration that allows the nanoparticles introduced from the drying unit 2200 to pass through by filtering the size or less by any one value selected from the range of 100 to 500 micrometers.

The pretreatment unit 3000 is a configuration including a cooling unit 3100 and an inert unit 3200 by cooling the nanoparticles introduced from the collecting unit 2000 and mixing them with an inert gas.

The cooling unit 3100 is configured to rapidly cool the nanoparticles flowing from the collecting unit 2000. The cooling unit 3100 is circulated in a state in which liquid nitrogen is recovered and reused without loss in a coil-shaped cooling pipeline, and an internal penetration is formed in the coil shape. As the nanoparticles pass through the path, the nanoparticles are rapidly cooled to any value selected from the range of minus 100 to 146 degrees Celsius, and preferably cooled to minus 146 degrees Celsius. The lower the cooling temperature, the lower the water content of the cooled nanoparticles.

The inert unit 3200 adjusts the inert gas to the cooled nanoparticles according to a control signal such that the inert gas is any one selected from the range of about 25 to 50% per unit volume, thereby preventing explosion. Preferably, the mixture is mixed at a volume concentration in the range of 30% per unit volume to prevent the nanoparticles from being exploded by various causes.

On the other hand, the inert gas is used by mixing any one selected from nitrogen gas, helium gas, argon gas or at least one selected.

The impact unit 4000 converts the nanoparticles pre-treated from the pretreatment unit 3000 into fine nanoparticles of 10 nanometers or less by sequentially applying physical impacts by multi-steps, and the first impact unit 4100 and the second. The impact portion 4200 is configured.

Since the first impact unit 4100 and the second impact unit 4200 have the same configuration as the four cycle internal combustion engine and operate in the same manner, the detailed configuration and operation description will be omitted and only necessary matters will be described.

A rotating shaft of a cam for driving the pistons constituting the first impact part 4100 and the second impact part 4200 to move up and down in a shape such as a four cycle internal combustion engine rotates by a separate drive motor. It explains by doing. The drive motor rotates at the RPM (rotation speed or rotation speed) designated by the corresponding control of the central control unit 6000, rotates to any value selected from the range of 1500 to 2000 RPM, 1500 RPM is relatively preferred. However, it is very natural that the rotation speed can be adjusted as needed.

Since the first impact part 4100 includes a cooling part 4020 through which refrigerant flows on the wall portion of the cylinder in which the piston reciprocates up and down, the first impact part 4100 forcibly cools the heat generated by the explosion.

The first impact unit 4100 injects liquid hydrogen into the nanoparticles introduced from the pretreatment unit 3000 through the injection unit 4040 operated by the control signal of the central control unit 6000. Inlet mixing may be performed to inject liquefied LPG gas as necessary. The injected and mixed gas is exploded by the sequential operation of the four cycles of the internal combustion engine and the action of the spark plug.

That is, the hydrogen gas or LPG gas introduced into the cylinder through the injection unit 4040 is used to generate only the explosive force, and the nanoparticles are further subdivided by the explosive force to form nanoparticles of finer size.

This inflow and mixing is driven in the same way as the intake process (cycle) by a four cycle internal combustion engine. On the other hand, it undergoes a compression process by the four-cycle internal combustion engine and explodes by the explosion process to apply a physical shock to the nanoparticles. At this time, the nanoparticles are further subdivided into fine nanoparticles, and are discharged by an exhaust process of a four cycle internal combustion engine.

The configuration and operation of the second impact unit 4200 is the same as the first impact unit 4100.

The second impact unit 4200 mixes and explodes hydrogen nanoparticles having a second concentration into the injection unit 4040 to the nanoparticles (fine nanoparticles) introduced from the first impact unit 4100 to physically impact the nanoparticles. Is applied.

Here, since the first concentration and the second concentration may be arbitrarily determined, detailed description will not be made.

The impact unit 4000 is coated with graphene on the inner wall of the cylinder in which the piston of the 4-cycle internal combustion engine moves up and down to reduce wear and increase heat conduction so that the cooling is smoothly performed while increasing efficiency.

The impact portion 4000 may further include a third impact portion, a fourth impact portion, and an nth impact portion, as necessary, and may further reduce its configuration. As the impact portion increases, the size of the generated fine nanoparticles can be said to be smaller.

That is, when the impact part 4000 further includes n impact parts, it is possible to mass-produce stable and excellent graphene. In addition, the number of components of the impact portion can be further reduced as necessary. In the case where the configuration of each impact portion is more precisely configured and the explosion force is adjusted, the number of components of the impact portion may be provided with the same result.

The sorting unit 5000 is configured to collect and concentrate the fine nanoparticles introduced from the impact unit 4000 in multiple stages by size, and include a collecting concentrating unit 5100 and a sorting unit 5200.

The collection concentrator 5100 collects the fine nanoparticles flowing from the impact unit 4000 and concentrates them to a specified density, and allows the nanoparticles to be charged at any one of negative polarity or positive polarity. Since it is a well-known configuration, detailed description thereof will be omitted.

The sorting unit 5200 is concentrated from the collecting and concentrating unit 5100 and charged or charged with one of negative (+) and positive (+) charges. It is a structure and includes the 1st roller part 5210, the 2nd roller part 5220, the 3rd roller part 5230, and the 4th roller part 5240. As shown in FIG.

6, the roller parts 5210, 5220, 5230, and 5240 provided with the charging part 5202 and the static eliminating part 5204 are well illustrated in detail in an enlarged state.

Each of the first roller portion 5210, the second roller portion 5220, the third roller portion 5230, and the fourth roller portion 5240 is formed of a pair of cylindrical rollers adjacent to each other and rotating in opposite directions. In the drawings, the adjacent portions are shown to be configured to rise upward, but may be configured to descend downward.

That is, the rotation direction of the rollers 5210, 5220, 5230, and 5240 may be changed as necessary, and the polarity of the voltage applied to each of the charging unit 5202 and the static eliminator 5204 may be changed. Yes, it is very natural.

Since the fine nanoparticles are so small in size, the separation distance A between the pair of cylindrical rollers adjacent to each other and rotating in opposite directions may be spaced at any one value selected from the intervals in the range of 100 to 500 micrometers. It is preferably configured to maintain a spacing of 100 micrometers.
