1 is a view showing a configuration of a ceramic bead manufacturing apparatus according to an embodiment of the present invention.
2 is a view showing a stirring tank according to an embodiment of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to or limited by the embodiments. Like reference symbols in the drawings denote like elements.

Hereinafter, a ceramic bead manufacturing apparatus will be described in detail with reference to FIG.

1 is a view showing a configuration of a ceramic bead manufacturing apparatus according to an embodiment of the present invention.

1, a ceramic bead manufacturing apparatus includes a stirring tank 100, a first overflow 200, a transfer pipe 300, a second overflow 400, a re-charging pump unit 500, 600).

Hereinafter, the stirring tank 100 will be described in more detail.

First, the stirring tank 100 includes a motor 110 for stirring the impeller, a slurry inlet port and slurry transfer pump 120 with a filter, a vacuum pump 131 and a suction bottle 132, a pressurizing compressor 133, A cold storage container 150 provided outside the slurry container, an impeller 160 having a plurality of blades, a slurry discharge valve 170 for viscosity measurement, a constant amount supply pressure pump 180, a filter 190, And a plurality of nozzles 195 may be provided.

More specifically, the impeller stirring motor 110 slowly rotates the impeller 160 having a plurality of blades to maintain the slurry viscosity in the slurry container 140 at a constant level to provide stability for a long time.

The slurry inlet with the filter and the slurry transfer pump 120 supply a predetermined amount of the slurry to the slurry container 140 for a predetermined period of time after the filter attached to the slurry inlet port passes through the slurry container 140 Can supply.

In other words, after a raw material and water are mixed and pulverized and dispersed, a slurry having been pulverized to a target size is pretreated, and only a certain amount of slurry in a fluid form is supplied to the slurry container 140 to maintain the vacuum state. My bubbles can be removed.

Next, the vacuum pump, the suction bottle, and the pressurizing compressor 130 can maintain the inside of the slurry container 140 under vacuum.

The reason why the vacuum is maintained in the slurry container 140 is that the bubbles generated in the pulverization and dispersion process of the raw material and the bubbles generated as the impeller in the slurry container slowly rotates can change the viscosity of the slurry.

Also, if the slurry is spheroidized and solidified by the substitution reaction, if the bubbles are present in the beads, the mechanical properties such as the strength and toughness of the beads are lowered. Therefore, the vacuum state in the slurry container 140 is maintained .

Next, the slurry container 140 has a cylindrical shape and may have a capacity of 10L to 100L.

The reason is that the productivity is too low if the volume is 10 L to 100 L, and if the volume is 100 L or more, the uniformity of the slurry can not be controlled due to the viscosity change of the slurry due to storage for a long time, This is because device control such as clogging does not work well.

Next, the cold storage container 150 is provided on the outer circumferential surface of the slurry container 140, and the temperature of the slurry container 140 can be maintained constant.

That is, a cooling / warming container 150 is provided outside the slurry container 140, and a cooling / heating material (cold water, hot water, refrigerant, etc.) is placed in a space between the cooling / heating container 150 and the slurry container 140 So that the slurry in the slurry container 140 can be kept warm.

The structure of the slurry container 140 and the cold storage container 150 and the detailed structure of the stirring tank will be described in more detail with reference to FIG.

2 is a view showing a stirring tank 100 according to an embodiment of the present invention.

2, the slurry contained in the slurry container 140 is rotated through an impeller stirring motor 110 and an impeller 160 having a plurality of blades, and the slurry container 140 and the cold / 150 may be cooled or maintained by introducing one of cold water, hot water or refrigerant.

That is, when the temperature is too high or too low, the viscosity of the slurry may change to cause a defective product having a low sphericity. In order to prevent this, Can cool (or maintain) the slurry container 140.

On the other hand, a slurry inlet 141 is provided at one side of the upper part of the slurry container 140 to feed the slurry in which the crushing dispersion and the binder are mixed to the slurry container 140, and a pressure gauge 142 is provided at the upper side, It is possible to confirm the pressure in the inner space 140 and to check the amount of the inner slurry through the upper viewing window 143.

The slurry discharge valve 170 is a valve for discharging the slurry to check the final viscosity after defoaming in the slurry container 140. The filter 190 has a mesh of 325 mesh or more to prevent clogging of the ultra- To remove large lumps in the slurry.

The pressurizing compressor 133 is a device for providing a vacuum for the interior of the slurry container 140. The pressurizing compressor 133 pressurizes the slurry container 140 through the vacuum pump 131 and the suction bottle 132 with the pressure provided by the pressurizing compressor 133 140 may be removed.

The constant amount supply pressurizing pump 180 is a pump for supplying a predetermined amount of slurry to the plurality of nozzles 195. The constant amount supply dispenser 181 transmits a signal to the constant amount supply pressurizing pump 180, ) To be supplied with a predetermined amount of slurry.

Referring again to FIG. 1, the impeller 160 having a plurality of blades is provided in the slurry container 140, and can rotate at a predetermined speed.

A plurality of impellers 160 are slowly rotated to continuously change the viscosity of the slurry in the slurry container 140 to maintain the viscosity of the slurry and to raise the bubbles in the slurry, ) To remove the bubbles and increase the purity of the slurry.

The slurry discharge valve 170 for viscosity measurement is coupled to the lower portion of the slurry container 140 and can be opened or closed to measure the viscosity.

More specifically, if the viscosity of the slurry from which the bubbles have been removed in the vacuum state is too high, the slurry falls off the ends of the plurality of nozzles 195 and hangs without falling, and if the viscosity is too low, The slurry in the slurry container 140 is discharged to confirm the prescribed viscosity. If the specified viscosity is not satisfied, the viscosity of the slurry container is adjusted by adding water or a binder dissolved in water. At this time, the viscosity should be maintained at 200 to 1200 cst depending on the size of the beads to be produced.

The filter 190 is provided between the fixed amount supply pressurizing pump 180 and the plurality of nozzles 195, and can pass a slurry having a predetermined size or smaller.

The reason why the filter 190 is installed is that the mass of the slurry arriving at the nozzle 195 may be larger than the size of the nozzle 195 and is likely to clog the nozzle so that the slurry inlet port and the slurry feed pump 120, and the second sludge is finely filtered in the filter 190, and then the sludge can be collected later and sent to the crushing vessel.

Next, the metering feed pressurization pump 180 is coupled to the bottom of the slurry container 140, maintains a vacuum in the slurry container 140, and can generate its own pressure by the motion mechanism of the pump itself.

As described above, no air should enter into the slurry container 140, and a pressure of a predetermined scale or more is required to drop small droplets through the precision nozzles. Instead of generating pressure in the pressurizing vessel, pressure is generated by the self- . That is, it is preferable that a pressure is generated in a pump supplied in a fixed amount so as to maintain a constant pressure for each nozzle as much as possible, and it is desirable not to attach more than 20 nozzles to one nozzle block in order to maintain a constant pressure.

Finally, a plurality of nozzles 195 are combined with a metering feed pressurization pump 180, and the slurry transferred from the slurry container 140 is sprayed or dropped to a predetermined size through a plurality of nozzles 195.

At this time, the plurality of nozzles 195 are coated with Teflon so that the liquid does not rise up. More specifically, when the slurry rides up along the tip of the nozzle, the shape is disturbed, so that the slurry can be prevented from sticking through the Teflon coating, and the nozzle can be made thinner and sharp than the conventional nozzle, Can be adjusted.

The number of the nozzles 195 may be from 1 to 20, and the slurry transferred from the slurry container 140 may be formed into small droplets of a predetermined size to be dropped into the first overflow 200.

A separate elevation device is attached to the nozzle 195 to adjust the gap between the nozzle and the reaction solution contained in the first overflow. The shape of the droplet that forms at the tip of the nozzle is determined according to the viscosity of the slurry So as to obtain a bead having a higher spherical shape.

Hereinafter, the first overflow 200 will be described in detail.

The first overflow 200 is spaced below the nozzle 195 and includes a chamber 210, a first displacement solution control vessel 220, a level sensor 230, a first ionic substituent 240, (250).

The reason for using the overflow method is that the overflow method is efficient and easy to manage when it is used to carry out a continuous ion replacement process.

First, the chamber 210 can receive small droplets that are ejected (or dropped) from the plurality of nozzles 195.

The reason why the chamber 210 is provided is that it is difficult to control the deformation and the reaction rate due to the impact due to the drop when the chamber 210 immediately falls into the first ion substituent 240. Therefore, A small droplet can be injected into the first ion substituent 240 after being accommodated.

The first replacement solution control vessel 220 can control the height of the displacement solution.

That is, when the replacement solution contained in the first ion substituent 240 maintains a certain level and the replacement solution is excessively supplied to the first ion substituent by the re-supply pump unit 500, The displacement solution moves (escapes) to the single displacement solution control vessel 220 to adjust the constant height.

The level sensor 230 can check the height of the displacement solution.

That is, the height of the replacement solution can be checked to serve as a sensor for notifying when the replacement solution in the first replacement solution control vessel 220 is supplied and when the stored solution is stored, to the re-supply pump unit 500.

Finally, the first ionic substituent 240 is a space in which small droplets spheroidize and solidify the shape through ion substitution.

That is, the small slurry droplets in the first ion exchanger 240 can be sent to the transfer tube 300 in a fixed shape and fixed in shape through ion exchange with the component contained in the replacement solution. On the other hand, a transparent transparent window 250 is provided on one side of the outer surface of the first ion substituent 240 so that small droplets can be detected.

Here, the formula for the ion substitution is as follows:

2 Na-Alginate (Sodium Alginate) + CaCl2 = Ca-Alginate (Calcium Alginate) + 2 NaCl

By the ion substitution reaction of sodium ion and calcium, the small droplets can maintain the circular shape while the surface is hardened by calcium.

Hereinafter, the conveyance pipe 300 will be described in more detail.

The transfer pipe 300 may include a spring hose 310 and an opening / closing nozzle 320.

First, the spring hose 310 is coupled to the lower portion of the first overflow 200 and may be provided with a predetermined length.

In one embodiment, the spring hose 310 may be a resilient hose and may be provided with a length of 50 meters.

The reason for providing the length of 50M is that since the droplets in the first overflow 200 do not end most of the reaction, only the form is kept at a minimum, so that the reaction is continuously generated in the elastic hose, To be able to give time to be formed.

The opening and closing nozzle 320 may be provided at the lower end of the spring hose 310 and may be opened when the weight applied to the end becomes a predetermined weight.

The reason that the opening and closing nozzle 320 is opened or closed according to the weight is that the small droplets collected in the first overflow 200 flow out to the second overflow 400 through the transfer tube 300 together with the replacement solution If the replacement solution contained in the first overflow and the second overflow can not be balanced, defective products may occur due to insufficient replacement solution in the first overflow. Therefore, when the replacement solution is filled in the spring hose and the replacement solution overflows in the first overflow, it must be opened and closed to exit to the second overflow.

Hereinafter, the second overflow 400 will be described in more detail.

The second overflow 400 may be spaced apart from the transfer tube and may include a Teflon network 410, a second ion substituent 420, a second replacement solution control vessel 430, . ≪ / RTI >

First, the Teflon net 410 may receive a small droplet flowing from the opening and closing nozzle 320, and may include a plurality of the droplets.

The reason why the surface of the Teflon net 410 is coated with Teflon is to prevent small droplets from sticking to the net.

In addition, a plurality of Teflon meshes can be provided. The reason why the Teflon meshes are provided is that the small droplets are not fixed in a solid shape, so that the small droplets accommodated in the lower side are prevented from being collapsed due to their weight. When a predetermined small amount of droplets are collected in the inside, the Teflon mesh can be replaced to prevent the shape of the small droplet from being deformed by the weight.

On the other hand, the second ion substituent 420 is provided outside the Teflon net 410 and is a space for causing ion exchange reaction with small droplets contained in the Teflon net 410.

In other words, when the ion replacement reaction of the small droplet transferred from the first overflow 200 is not completed, the second ion substituent 420 can induce a continuous reaction.

Next, the second replacement solution control vessel 430 is provided on the side of the second ion substituent, and can control the displacement solution of the second ion substituent.

That is, the second replacement solution control vessel 430 may perform the same function as the first solution control vessel 220 described above.

Finally, the bubble generating pipe 440 is provided below the Teflon net 410 and can generate bubbles.

That is, the bubble generating pipe 440 generates bubbles to continuously rotate the small droplets in the Teflon net 410 to promote the reaction, and the small droplets accommodated in the lower part of the Teflon net 410 are added to the weight of the small droplets So as to prevent the shape from being changed.

Therefore, the bubble generating pipe 440 generates bubbles until the Teflon net 410 is replaced, thereby protecting the shape of the small droplet inside the Teflon net 410 from being deformed. When the Teflon net 410 is a certain weight, the Teflon net 410 Can be replaced to prevent the small droplets from being deformed by the weight.

Hereinafter, the re-injection pump unit 500 will be described in more detail.

The reclosing pump unit 500 is provided below the second overflow and may include a circulating hose 510 and a circulation pump 520. [

First, the circulation hose 510 may be connected from the bottom of the second overflow 400 to the top of the first overflow 200.

The reason why the circulating hose 510 connects the first overflow 200 and the second overflow 400 is that the height of the replacement solution of the first overflow 200 and the second overflow 400 And may return the replacement solution dropped from the first overflow 200 to maintain a constant level of the replacement solution accommodated in the first overflow.

That is, when the level sensor 230 checks the lack of the replacement solution of the first ion substituent 240, the replacement solution of the second ion substituent is received by the circulation hose 510, the circulation pump 520 operates, The solution can be transferred to the first ion substituent 240.

At this time, since the displacement solution can not be transferred to the first overflow 200 at the upper part due to the force of the circulation hose 510, the second overflow and the circulation hose 510 are utilized by utilizing the power of the circulation pump 520, To the first overflow (200).

Hereinafter, the operation unit 600 will be described.

The control unit 600 may perform at least one of monitoring the vacuum state of the stirring tank, monitoring the supply state of the replacement solution and slurry, and controlling the pump operation.

In other words, it checks the vacuum state in the stirring tank to the same place as the control tower of the whole apparatus, checks the overall condition of the apparatus through the height of the replacement solution, the supply state of the slurry, Can operate.

Hereinafter, an embodiment of the process of moving the slurry in the ceramic bead production apparatus will be described.

First, raw materials (yttria-stabilized zirconia powder prepared by a high-quality hydrothermal method having primary particles of 30 to 40 nm) pulverized through a pulverizing and dispersing machine were subjected to a one-stage pulverization in a pulverizing and dispersing machine using 1.0 mm, All the raw materials can be pulverized to 1 micron / μm or less through two-stage pulverization in the ultra-fine particle grinding and dispersing machine, and then can be introduced into the stirring tank 100.

The raw material slurry mixed with the raw material slurry mixed with the aggregate of the zirconia particles that have been pulverized and dispersed in a binder (e.g., sodium alginate: not more than 1 um) in the slurry container 140 of the stirring tank 100 is stirred for 3 hours (200-1200 cst) for each size of the beads to be produced by adding water or a binder to the beads, and if it is determined that the viscosity is appropriate, the slurry is supplied to the plurality of nozzles 195 through the filter 190 .

The slurry is injected or dropped into the first overflow 200 through the nozzle 195.

The slurry injected or dropped into the first overflow 200 is subjected to sodium-calcium ion substitution by the first ion substituent 240, and the surface of the slurry is cured by calcium to be able to maintain the shape of the sphere.

Here, the level sensor 230 can measure the height of the solution so that problems such as insufficient or excessive replacement solution of the first ion substituent 240 are not generated. When the height of the solution is raised by the level sensor 230, the first replacement solution control vessel 220 performs the displacement solution control.

Meanwhile, the slurry in which the reaction has been completed in the first overflow 200 enters the transfer pipe 300. At this time, the transfer pipe is continuously subjected to the substitution reaction within the elastic long length of the spring hose 310, And when the weight of the slurry applied to the opening and closing nozzle 320 becomes equal to or greater than a predetermined weight, the opening and closing nozzle 320 is opened To the second overflow (400).

The second overflow 400 collects the beads together with the last substitution reaction. The slurry is injected from the opening / closing nozzle 320 and stays in the Teflon net 410 inside the second ion exchanger 420, The bubbles generated in the production pipe 440 can prevent the lower slurry from being crushed and deformed depending on the weight of the slurry.

In addition, the Teflon net 410 is configured to be replaceable when the weight of the Teflon net 410 is a predetermined weight, so that a small amount of the Teflon net 410 can be divided and stacked to prevent deformation due to the weight of the bead finally.

As described above, the present invention provides a ceramic bead manufacturing apparatus for preventing deformation of beads caused by air and generation of bubbles therein by keeping the inside of the apparatus in vacuum.

The present invention provides a ceramic bead production apparatus having a two-stage overflow and a reclosing pump to improve productivity.

The present invention provides a ceramic bead manufacturing apparatus for producing a bead having a uniform shape by using a Teflon coated spray nozzle.

The present invention provides a ceramic bead manufacturing apparatus for preventing the shape of a bead from being deformed by weight by loading and separating a small amount of finished beads into a plurality of Teflon webs.
