Abstract

A refining method and its related system are disclosed in the present invention. The refining objects having the same hardness are grinded via vibrating under the resonant frequency of the refining object until the particle size of the refining object approaches to the target value. As the particle size of the refining object approaching to micro-scaled or even nano-scaled, the physical and/or chemical properties of the refining object are varied. Hence, the resonant frequency of the refining object is varied during the entire refining process if necessary. Meanwhile, the refining objects collide with each other via the physical forces such as the gravity, any other forces and any types of the acceleration forces. Thus, in the present invention, the refining objects are physically grinded and collided because of the same hardness of the material. Comparing to the conventional refining method, the grinding medium and/or slurry are required. The refining procedures and the system can be greatly simplified as the refining efficiency is still high.

Description

Refinement method and system

The present invention discloses a thinning method and its system, in particular, it relates to a thinning method and its system, which is completely through the collision between the thinning body and the thinning body due to resonance, and through the thinning The main body and the refined main body have the impact of acceleration to achieve the refined effect.

In the conventional technology, the refining method often used is grinding, but in order to make the refining body uniformly dispersed and completely ground during the grinding process, more of the above objectives are achieved by adding grinding media, and at the same time The liquid grinding liquid is used to carry out the grinding process. This process and the so-called wet dispersion grinding technology are based on the conventional wet dispersion grinding technology, which first drives the refinement of the main body and the high hardness grinding medium through mechanical force , Make the high-hardness grinding media collide and rub against the refining body, so as to break the refining body, and then add grinding liquid to wet the broken refining body and grinding medium, and then use other mechanical devices to agitate the refining body. The polishing mixture of the main body, the polishing medium and the polishing liquid enables the thinning body and the polishing medium in the mixed liquid to collide with each other at high speed under the action of shear force to produce the polishing effect. Finally, the refined body whose particle size has reached the target can be separated and collected from the grinding medium by screening.

However, due to the relatively high hardness of the grinding media, in the state of high-speed stirring, in addition to colliding with the thinning body, it is also easy to cause wear and damage to the mechanical device, making the components in the mechanical device a necessary consumable; and In order to achieve the best grinding effect, the various parameters of mechanical grinding must be controlled fairly accurately, and the design and configuration between the components are also quite complex and precise. In addition, in the conventional wet dispersion grinding technology, in addition to the refined main body after grinding In addition to the relatively small particle size, the grinding media used is also quite fine, which is easy to cause blockage and wear on the pores of the screening element (such as the screen) during the screening process. The separation effect is severely reduced. In other words, even if a good refinement effect can be achieved in the grinding process, under the limitation of the final screening mechanism, a sufficient amount of refinement body may not be obtained.

In view of the above problems, the present invention discloses a thinning method and system, which achieves the thinning effect by colliding and impacting the thinning bodies of the same hardness with each other, without the need to add additional grinding media, thus effectively avoiding the conventional technology It is difficult to sieve in the middle, while still maintaining an excellent thinning effect.

The main object of the present invention is to provide a thinning method and a system thereof. By the collision between the same thinning body and the thinning body due to resonance and the impact due to acceleration, the thinning body and the thinning body The main bodies are constantly colliding and colliding to achieve the effect of refinement.

Another object of the present invention is to provide a refining method and its system, which can simultaneously change the resonant frequency of the refining body due to changes in the physical and chemical properties of the refining body during the refining process, and The vibration frequency provided by the system is adjusted accordingly, so that the refined main body can resonate continuously and collide effectively.

A further object of the present invention is to provide a refining method and system, which does not require additional addition of grinding media and grinding fluid, so in subsequent screening, there is no need to sieve between the grinding media and the refining body Points, you can get a high-purity refinement body, while also improving the efficiency of refinement.

To achieve the above purpose, the present invention discloses a thinning method, which includes the following steps: first, providing a plurality of thinning bodies; in the second step, the thinning bodies are vibrated at a specific frequency to resonate the thinning bodies And collide with each other; in the third step, output some of the refined main body; In the fourth step, return some of the refined bodies to hit the unrefined bodies; in the fifth step, detect the particle size of the refined bodies to adjust the frequency; repeat the above steps, and finally, collect These refined bodies with specific particle sizes. At the same time, the present invention also discloses a refinement system, which includes a body, a conveying unit and a particle size detection unit, wherein the system has at least one vibrating element, at least one space and two openings, the vibrating element is a Vibrate at a frequency; the conveying unit has an output port and an input port, wherein the output port and the input port are respectively arranged corresponding to the two openings of the body; the particle size detection unit is arranged at least one corresponding to the body and the conveying unit , And can transmit at least one signal to control the vibration frequency output by the vibrating element; the collection unit is connected to the body to collect the refined bodies whose particle size reaches the target; wherein, the plural refined main system is placed in the body and based on The thinned bodies adjust the frequency of the vibration element and cause the thinned bodies to resonate correspondingly and collide with each other. After the collision, the thinned bodies enter the conveying unit through the output port corresponding to the opening of the body, and pass through the conveying unit. And again, the input port corresponding to the opening of the body enters the body from the space, and the refined main systems that reenter the body hit the refined bodies that are not output, and the particle size detection unit detects the refined bodies. When the particle size is fine to a certain range, the frequency of the vibration element will be controlled according to the characteristics of the refined bodies to generate signals, so that the refined bodies whose physical properties and chemical properties have been changed can continue to effectively resonate and repeat In the manner of the above process, the collision and collision of the refined bodies are continued until the particle size of the refined bodies reaches the desired target, and then the collection unit collects the refined bodies.

Therefore, the refining method and system disclosed in the present invention are based on the collision and impact between the refining body and the refining body, without the need to add additional grinding media and grinding fluid, under the collision and impact of the refining bodies with the same hardness To achieve the purpose of refinement, and in order to improve the degree of refinement, the frequency of vibration will be adjusted as the size, physical properties, and chemical properties of the refinement body change, so that the refinement body can produce effective resonance motion. In addition, In addition to generating collisions by refining the resonance of the body, when the refining bodies collide with each other, they can also use the added gravity, force field, electric field, magnetic field or flow field. In order to make the refined main body collide under the condition of acceleration, so as to increase the impact effect, achieve more excellent refinement effect, and save the manufacturing time. In addition, since no additional grinding media and grinding liquid are added, the separation step can be omitted in the final screening and collection process, and there is no need to add additional grinding media and grinding liquid, which directly improves the separation and collection effect, and Indirectly improves the yield of the final refinement.
