Polymer dispersion system using a homogenizer {Polymer dispersion system}

The present invention relates to a polymer dispersion system using a homogenizer designed to mix a polymer powder and a liquid fluid in order to disperse the polymer in a liquid phase. A polymer composed of fine powder particles is provided with a plurality of mixers for mixing the polymer powder and the fluid. The present invention relates to a polymer dispersion system using a homogenizer that improves the mixing ratio of and liquid fluid, and provides reliability by controlling each mixer independently.

In general, various industrial materials composed of fine powder particles such as cosmetics, paints, abrasives, etc. are generally manufactured through a process of mixing various raw materials and then milling them into fine particles.

To this end, conventionally, raw materials are mixed by rotating a mixing blade in a container using a separate mixing device, and then the mixture is put in a grinder to perform pulverization treatment.

The mixing device includes an inlet portion for introducing a mixture of raw materials, a screw shaft for transferring the input mixture into the chamber, and a repelling plate and a rotor portion for pulverizing the mixture introduced into the chamber.

According to this configuration, when the raw material mixed through the mixing device is supplied through the inlet, the raw material is transferred into the chamber by rotation of the screw shaft. In addition, in the chamber, the rotor part rotates at a low speed or high speed with respect to the repelling plate. At this time, the hammer and the repelling plate movably coupled along the outer circumference of the rotor part mechanically contact each other with the raw material interposed therebetween, thereby crushing It goes on.

However, such a conventional mixing and pulverizing system is very cumbersome and requires a lot of work time because it is necessary to put the raw materials mixed through the mixing device in a predetermined container and put it back into the pulverizing device, and due to the time interval between the mixing operation and the pulverizing operation. There was a problem in that the mixed raw materials precipitated or aggregated again.

In addition, due to the agglomeration phenomenon between the input raw materials, the mixing ratio between the fluid and the raw materials is lowered, or malfunctions and defects of the apparatus occur frequently due to the transfer of the aggregated raw materials.

In addition, the powder mixing device as described above has a vulnerability of increasing the volume of the device as well as power consumption because a separate screw shaft must be configured to rotate so as to introduce raw materials into the chamber.

Accordingly, there is a need to develop a polymer mixing device with diversity because it improves the mixing ratio of the fluid and the raw material, reduces the occurrence of malfunction of the device, and allows the mixing ratio of the fluid and raw material to be adjusted.

The present invention has been devised to solve the above problems, and provides an optimum mixing ratio by measuring the input amount of the polymer in the form of a fine powder and the weight of the fluid in the liquid state, and distributing the mixture according to the process of using the mixed mixture.

In addition, a raw material transfer unit 4000 for receiving raw materials from the raw material input unit 1000 and transferring the raw materials to the raw material mixing unit 3000 is provided. The raw material transfer unit 4000 receives the raw material from the raw material input unit 1000 and transfers the raw material to the raw material mixing unit 3000, which pulverizes the raw material into a predetermined size while being transferred. That is, the raw material is a powder having fine particles, and these raw materials are agglomerated with each other depending on the ingredients of the raw material. When the raw materials are transported to the raw material mixing unit 3000 while the raw materials are aggregated, there is a problem that the raw materials cannot be well mixed with the liquid fluid.

Therefore, if the raw materials aggregated in the raw material transfer unit 4000 are pulverized to a certain size or transferred to the raw material mixing unit 3000 while maintaining the raw materials in a powder form, the mixing ratio in the raw material mixing unit 300 can be further improved. have.

A plurality of contact protrusions (3231-1, 3232-2, 3233-1) that are spaced apart and formed are formed. Preferably, the spacing of the contact protrusions 3233-1 formed in the third stator 3233 is greater than the spacing of the contact protrusions 3231-1 formed in the first stator 3231 so that the raw material and the fluid can be better mixed.

A casing 3260 is further provided. That is, as the adapter 3250 and the casing 3260 are mounted on both sides of the casing 3260 so that they are mutually sealed, the primary mixture may be accommodated in the inner space.

At this time, in the inner space of the casing 3260, as the rotor assembly 3240 rotates, the introduced primary mixture flows through the inner space of the rotor assembly 3240 and the casing 3260, and is homogenized by contacting the stator assembly 3230. Proceeds to form a secondary mixture. Then, an outlet 3261 is provided on the side of the casing 3260 so that the homogenized secondary mixture is discharged to the outside by the rotational force of the rotor assembly 3240.

Referring to the enlarged view of FIG. 2, a gas flow path 3223 for receiving gas flowing into the gas inlet 3221 of the stator holder 3220 is formed at the inner edge of the main inlet h.

In addition, the first and second stators 3231 and 3232 have gas holes 3231-2 and 3232 communicating with the gas flow path 3223 in order to introduce gas from the gas flow path 3223 into the internal space of the stator holder 3220. Each -2) is perforated. At least one gas hole 3231-2 and 3232-2 may be formed along the circumferential surfaces of the first and second stators 3231 and 3232. As gas of a predetermined pressure is introduced into the internal space of the gas stator holder 3220, the homogenized secondary mixture may be smoothly discharged to the outlet 3261 of the casing 3260.

Referring to FIG. 1, a third mixer 3300 having a hollow interior is provided to receive a secondary mixture homogenized by a second mixer 3200 and receive a predetermined amount. The third mixer 3300 continuously agitates the received mixture using a separate stirrer to prevent separation of fluid and raw materials from the received mixture. The above stirrer corresponds to a known stirrer including a motor and a stirring blade.

Referring to FIG. 1, the mixture accommodated in the third mixer 3300 is discharged to the outside according to the following process. At this time, a storage tank 6000 for receiving a predetermined amount of the mixture discharged from the third mixer 3300 is further provided. The storage tank 6000 has at least one first storage unit 6100 and a second storage unit 6200 connected in series or in parallel with the third mixer 3300. Due to the configuration of the storage tank 6000, the mixture can be separately accommodated according to the intended use, and additional additives or fluids can be supplied in each storage tank 6000 to store different concentrations. .

When the operation of the fluid supply unit 2000 is described in detail, when the fluid is supplied to the first mixer 3100, the flow rate of the supplied fluid must be adjusted according to the input amount of the raw material. At this time, since it is difficult to control the precise supply amount only by opening and closing the valve, when a certain amount of flow is supplied to the first mixer 3100, the supply of the residual fluid is assisted by shutting off the main valve 2200 and opening the auxiliary valve 2400. The fluid is bypassed through the supply pipe 2300 and supplied to the first mixer 3100.
