Description

Technology Field

[0001] The present invention relates to a powder suction type dispersion and homogenization system, and more specifically, to a powder suction type dispersion and homogenization system capable of achieving the highest degree of dispersion and homogenization by passing a functional powder and a metal powder, which have undergone a primary mixing and dispersion process, through a chamber-type multi-stage impeller that continuously processes the dispersion by sucking in and mixing and dispersing the dispersion by means of sound in addition to a primary mixing and dispersion (Pre-mixing) process in a high-viscosity liquid. Background Technology

[0003] As the nanomaterials industry advances, the methods of handling materials are becoming increasingly complex and sophisticated.

[0004] From basic materials industries such as food, cosmetics, ink, paint, adhesives, and coatings to fine chemicals, nanomaterials, and advanced electronic materials, the influence determining quality—ranging from particle fineness and uniformity to process stability—is becoming increasingly significant.

[0005] Technologies that enable such fineness and homogenization include “grinding,” “dispersion,” “emulsion,” and “homogenization.”

[0006] Meanwhile, there are limitations in that it is difficult to process various materials using existing emulsification, dispersion, and homogenization technologies and equipment when the viscosity is high (approximately 50,000 cps or more), when the specific gravity of the powder is low and the dispersion is high, or when there is a possibility that the properties may change during dispersion or emulsification due to the characteristics of the material.

[0007] In fact, the biggest obstacle is that due to the characteristics of the materials, they have high viscosity, making it difficult to mix them together, or the substances to be mixed have low specific gravity and float on the surface, making dispersion and homogenization difficult. Additionally, unlike the small experimental stage, it is not easy to handle large quantities in the industrial stage, so technology is required to effectively disperse and homogenize them in a short period of time.

[0008] For example, in the nanomaterial industry, such as secondary battery active materials, the commercialization of materials with small nanoparticles 1 / 1,000 the size of fine dust is leading to a need for dispersion technology with a higher level of uniformity to keep up with this trend. However, while it is necessary to homogenize metal powders and materials exhibiting active material functionality by mixing them in high-viscosity liquids, this process currently requires very large multi-stage facilities and is a highly difficult task.

[0009] In particular, with a homogenizer used in a general batch process, it is difficult to mix light particles that tend to float on the surface of a high-viscosity liquid with heavy metal powders that tend to sink to the bottom, and there is even a risk that harmful particles such as metal powders may scatter and endanger the hygiene of workers.

[0010] The inventor's prior application, Korean Published Patent Application No. 10-101658410, "High-viscosity fluid dispersion emulsification device," discloses a high-viscosity fluid dispersion emulsification device comprising a housing having a solid dispersion inlet and a liquid dispersion medium inlet formed on one side and a mixed fluid discharge outlet formed on the other side, a stator installed inside the housing, and a rotor disposed inside the housing and rotated by a motor. This device ensures safety during operation by completely blocking the risk of powder dust scattering, while enabling continuous dispersion and discharge of powder by sucking it into a high-viscosity liquid under negative pressure.

[0011] However, in the case of the secondary battery active material described above, since high-uniformity dispersion and homogenization technology is required, a more precise homogenization process is necessary in addition to the primary mixing dispersion (Pre-Mixing) process of mixing the powder exhibiting the functionality of the active material and the metal powder into a high-viscosity liquid.

[0012] Accordingly, the inventors discovered that by introducing a base material and a solvent into a large container and providing two vertical stirring blades linked to a drive shaft in a batch manner, the emulsification dispersion efficiency can be improved even for powders of various specific gravities and materials of different viscosities, while also achieving the highest degree of dispersion and homogenization by passing through a chamber-type multi-stage impeller that processes continuously to disperse into fine particles, and thus completed the present invention.

[0015] The present invention aims to provide a powder suction type dispersion and homogenization system to solve the above problems.

[0016] Another objective of the present invention is to achieve high-level dispersion and homogenization by combining a dual stirring blade type dispersion emulsification system, which is equipped with two upper and lower stirring blades linked to a drive shaft in a batch manner after introducing a base material and a solvent into a large container, thereby improving the emulsification dispersion efficiency even for powders of various specific gravities and materials of different viscosities.

[0017] In addition, the present invention aims to provide a suction-type dispersion and homogenization system capable of achieving high levels of dispersion and homogenization while dispersing a slurry into fine particles by passing it through a chamber-type multi-stage impeller that is continuously processed in the suction-type dispersion and homogenization system.

[0018] However, the objectives of the present invention are not limited to those mentioned above, and other unmentioned objectives will be clearly understood by those skilled in the art from the description below. means of solving the problem

[0020] To achieve the above objective, a powder suction type dispersion and homogenization system according to an embodiment of the present invention may be characterized by including a dispersion homogenizer (110) that mixes a solvent in a liquid state and a base material, a powder suction mixing disperser (120) that sucks in a stirring material that is primarily mixed and dispersed in the dispersion homogenizer (110) while simultaneously sucking in and mixing a powdered body with negative pressure and flowing it into a passage according to the flow of the fluid, and a chamber-type multi-stage impeller (130) that passes the stirring material introduced from the powder suction mixing disperser (120) and disperses it into fine particles, and performs a dispersion emulsification function.

[0021] At this time, the dispersion homogenizer (110) may be characterized as a batch-type double stirring blade dispersion emulsification device that can disperse and homogenize powders of various specific gravities and substances of different viscosities by being equipped with two stirring blades that rotate in both upward and downward directions linked to a drive shaft after introducing a base material and a solvent into a container.

[0022] In addition, the chamber-type multi-stage impeller (130) may be characterized as a rotor-rotor type multi-stage impeller in which the impeller inside the chamber is configured in multiple stages and driven by different motors in the upper and lower sections to rotate in different directions.

In describing the present invention below, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the present invention, such detailed description will be omitted.

FIG. 2 and FIG. 3 are drawings for explaining the structure of a powder suction mixing disperser (120) among the powder suction type dispersion and homogenization device (100) used in a powder suction type dispersion and homogenization system (1) according to an embodiment of the present invention.

FIG. 5 is a drawing showing a powder suction type dispersion and homogenization system (1) according to an embodiment of the present invention. FIG. 6 is a dispersion test result by a powder suction type dispersion and homogenization system according to an embodiment of the present invention.

[0029] First, referring to FIG. 1, the present invention is intended to solve the above problems and may include a dispersion homogenizer (110) equipped with two stirring blades in the upper and lower directions to homogenize a solvent in a liquid state, a powder suction mixing disperser (120) that uses negative pressure to suck up the stirred solvent of the dispersion homogenizer (110) while simultaneously sucking up a chemically active powdered body, and a multi-stage impeller that provides a stirred substance through a passage using the direction of force by the fluid while mixing with negative pressure, a chamber-type multi-stage impeller (130) that performs the function of finely shearing particles through a rotor, and a control device (140).

[0030] More specifically, in one embodiment of the present invention, the dispersion homogenizer (110) can perform a primary dispersion emulsification process for the solvent using two stirring blades that rotate in an upward and downward direction, one positioned upward and the other downward for the solvent.

[0031] In addition, the powder suction mixing disperser (120) has a structure that enables dispersion by suctioning a dispersion mixed with a solvent together with nano powder as shown in FIG. 2, thereby solving problems regarding the working environment and worker safety caused by powder scattering.

[0032] For example, while the quality of the finished ink improves as pigment powder particles become smaller, finer particles pose difficulties in handling and can increase risks to the working environment. In particular, during the process of adding pigments to tanks containing varnish, powder dispersion (such as fine dust) inevitably occurs. If workers inhale this, it can have adverse health effects. Furthermore, it not only contaminates the workplace floor, walls, and ventilation systems but, in severe cases, carries the risk of a major accident due to dust explosions caused by adsorption onto machinery surfaces.

[0033] Ultimately, while acknowledging that it has the advantage of high quality, it also has the disadvantage of the risk of fine powder scattering. In order to solve the problem and enable safe handling, the powder suction mixing disperser (120) can be configured as a continuous process by using a suction rotor that generates negative pressure to enable circulation by directly sucking in nano powder.

[0034] That is, a structure can be provided in which a liquid dispersion and a nano powder are mixed by an impeller on a powder suction mixing disperser (120), and a suction rotor that sucks in the dispersion impeller and the nano powder is positioned back and forth within the chamber, so that while rotating at high speed, dispersion is achieved and a negative pressure suction force is generated.

[0035] By providing a discharge rotor (122) on a powder suction mixing disperser (120) in a structure as shown in FIG. 3, conditions can be provided to ensure that suction and discharge are maintained in a constant rhythm.

[0036] In this way, the powder suction mixing disperser (120) can use negative pressure to suck in the stirred solvent while simultaneously sucking in the chemically active powder through the suction rotor (121), and can provide the stirred material to the multi-stage impeller through a passage utilizing the direction of force by the fluid through the discharge rotor (122).

[0037] Meanwhile, the one-pass type chamber-type multi-stage impeller (130) can perform the function of finely dispersing and emulsifying particles in the mixed dispersion liquid provided from the powder suction mixing disperser (120) through the rotor, while simultaneously dispersing them into fine particles. To this end, the chamber-type multi-stage impeller (130) may be characterized as an upper and lower multi-stage stacked impeller. By maintaining a gap of 0.2 mm between the impeller rotor and the stator and rotating at 3000 to 6000 rpm, it not only crushes the particles in the mixed dispersion liquid into fine particles but also enables dispersion and emulsification.

[0038] Referring to Fig. 4, the pump and impeller are fused, and when the pump transports a high-viscosity material to the main body of the system, the multi-stage impeller (each stage is equipped with a 3-stage rotor and stator, and there is a structure in which at least 5 stages are stacked) emulsifies and disperses the material and discharges it. Due to the characteristics of this impeller, any high-viscosity material can be perfectly emulsified and dispersed in a single pass in one cycle without circulating dispersion, thereby providing a groundbreaking effect that significantly reduces time and cost compared to conventional 3-roll mills or bead mills.

[0039] In addition, the chamber-type multi-stage impeller (130) has a multi-stage impeller inside the chamber, which is driven by different motors in the upper and lower sections to enable high-speed rotation in different directions, thereby applying a lot of energy to the particles and increasing the shearing ability to break them into fine particles.

[0040] At this time, to prevent the temperature from rising due to high-speed rotation, a structure can be configured in which a chamber-type multi-stage impeller (130) is wrapped with a jacket through which cooling water flows.

[0041] Meanwhile, the control device (140) can receive information through a sensor unit (not shown) to enable frequent replacement of the structure and direction of the impeller in order to prevent material clumping caused by a power outage due to an overload caused by an increase in high-speed dispersion force for material clumping caused by abnormal operation of the chamber-type multi-stage impeller (130), and provide this information to the manufacturing management server (300) through the network (200), thereby making it possible to apply a change in the structure and direction of the impeller to the stacked structure of the shaft.

[0042] In addition, the control device (140) for material clumping due to abnormal operation provides a powder suction type dispersion and homogenization system characterized by applying a shaft in a vertical structure so that the structure and direction of the impeller can be changed frequently to prevent material clumping caused by power outage, as an overload occurs due to increased high-speed and high-shear dispersion force.

[0043] In addition, the control device (140) for material clumping due to abnormal operation can receive information through a sensor unit (not shown) and provide it to an administrator terminal so that the structure and direction of the impeller can be changed frequently in order to prevent material clumping caused by power outage, as an overload occurs due to the high-speed dispersion force increase of material clumping due to abnormal operation of the chamber-type multi-stage impeller (130), thereby making it possible to apply a change in the structure and direction of the impeller to the vertical structure of the shaft.

[0044] Referring to FIG. 5, a powder suction type dispersion and homogenization system according to an embodiment of the present invention may include a plurality of powder suction type dispersion and homogenization devices (100), a network (200), a manufacturing management server (300), and an administrator terminal (400).

[0045] The manufacturing management server (300) can receive flow rate information provided from flow rate sensors corresponding to sensor parts at the upper and lower ends of the dispersion stator inside the dispersion impeller (132), and at the middle and lower ends of the internal middle and bottom ends of the suction and dispersion stator, respectively, from each powder suction type dispersion and homogenization device (100) through the network (200).

[0046] Afterwards, the manufacturing management server (300) can receive the first to fourth flow rate sensing values ​​corresponding to the first flow rate sensing value corresponding to the outflow rate flowing out from the upper point inside the dispersion stator, the second flow rate sensing value corresponding to the outflow rate flowing out from the dispersion rotor at the lower end inside the dispersion stator, the third flow rate sensing value corresponding to the outflow rate flowing out from the first suction and dispersion rotor at the middle end inside the suction, and the fourth flow rate sensing value corresponding to the outflow rate flowing out from the second suction and dispersion rotor at the lower end inside the suction, and store them in the DB as unit sensing information along with the terminal identification number of each powder suction type dispersion and homogenization device (100).

[0047] Afterwards, the manufacturing management server (300) can collect the first to fourth flow rate sensing values ​​of the homogenizing material according to the use or capacity of the homogenizing material from a plurality of powder suction type dispersion and homogenizing devices (100), and control them to be stored in the DB distributed by each use or battery capacity on its own big data-based DB.

[0048] And, the manufacturing management server (300) receives information on the use of the homogenizing material or the capacity of the homogenizing material for the secondary battery to be manufactured from the administrator terminal (400) via the network (200), and can extract range information which is an allowable flow rate range corresponding to the first to fourth flow rate sensor values ​​extracted from the DB that matches the use of the homogenizing material or the capacity of the homogenizing material.

[0049] In addition, the manufacturing management server (300) also stores external characteristic information, including weather and temperature changes during manufacturing, corresponding to the regional information of the powder suction type dispersion and homogenization device (100), in the DB. Subsequently, the manufacturing management server (300) compares the external parameters (weather, temperature, etc.) stored in the DB with the external parameters provided by the manager terminal (400), takes the case with the largest number of matching items as a selection criterion, extracts range information, which is an allowable flow rate range corresponding to the first to fourth capacity sensor values ​​extracted according to the selection criterion, and transmits it to the manager terminal (400) via the network (200), thereby enabling the manager terminal (400) to utilize the range information to manufacture a secondary battery that matches at least one of the application and capacity for the powder suction type dispersion and homogenization device (100).

[0050] Meanwhile, the manufacturing management server (300) can perform storage in the DB based on learning by applying an ensemble structure composed of multiple mutually complementary machine learning algorithms to improve the accuracy of quantitative numerical results of information collection and extraction according to external parameters and usage and capacity information.

[0051] That is, the manufacturing management server (300) can use one of the following machine learning algorithms as a machine learning algorithm used in the analysis / control program for storage and extraction: a Decision Tree (DT) classification algorithm, a Random Forest classification algorithm, or a Support Vector Machine (SVM) classification algorithm.

[0052] The manufacturing management server (300) can analyze collected data distributed and stored in a DB according to purpose and capacity by a distributed file program, extract external parameters which are multiple feature information as a result of the analysis, and learn the extracted feature information using at least one of multiple machine learning algorithms to generate extracted information as a result of the learning.

[0053] That is, the manufacturing management server (300) can apply an ensemble structure composed of multiple mutually complementary machine learning algorithms to improve the accuracy of the extracted information results.

[0054] Decision Tree classification algorithms derive results by learning through a tree structure, making result interpretation and understanding easy, offering fast data processing speeds, and enabling rule derivation based on search trees. Random Forests (RF) can be applied as a measure to improve the low classification accuracy of Decision Trees (DT). Random Forest classification algorithms derive results by training multiple DTs as an ensemble; while the results are more difficult to understand than DTs, they can offer higher accuracy. Support Vector Machines (SVM) can be applied as a method to address overfitting that may occur during DT or RF training. SVM classification algorithms classify data belonging to different categories based on a flat plane; they generally possess high accuracy and, structurally, may have low sensitivity to overfitting.

[0055] As described above, the suction-type dispersion and homogenization system of the present invention provides a suction-type dispersion and homogenization system capable of achieving the highest degree of dispersion and homogenization by adding a primary mixing and dispersion (Pre-mixing) process to a high-viscosity liquid, and then passing a functional powder and a metal powder, which have undergone the primary mixing and dispersion process, through a chamber-type multi-stage impeller that continuously processes them while mixing and dispersing them by suction using a sound source.

[0056] Referring to FIG. 6, the excellence of the dispersion test results by the powder suction type dispersion and homogenization system according to an embodiment of the present invention can be confirmed.

Although specific terms have been used, they are used merely in a general sense to facilitate the explanation of the technical content of the invention and to aid in understanding the invention, and are not intended to limit the scope of the invention.
