Description

분체 혼합 및 미분 제어 장치Powder mixing and fine control device
본 발명은 분체의 혼합 공정과 분체 중에 존재하는 미분량을 제어하는 공정이 하나의 장치 내에서 이루어질 수 있는 분체 혼합 및 미분 제어 장치에 관한 것이다.The present invention relates to a powder mixing and fine powder control apparatus in which the mixing step of powder and the step of controlling the amount of fine powder present in the powder can be made in one apparatus.
일반적으로 분체를 사용하여 물질을 제조할 때 사용 용도에 따라 분체 중에 포함된 미분량을 적절히 제어하는 것이 필요하다. 예를 들어 2차 전지용 전극 제조에 사용되는 활물질 분체를 제조할 때, 원하는 입자 크기를 갖는 분체를 제조하기 위해 분쇄 공정을 통해 큰 입자들을 작게 부수고 구형화하는 분쇄공정을 수행하며, 분쇄 공정을 통해 생산된 분체들을 혼합하여 사용용도에 맞는 균질화된 분체를 생산한다. 그러나 분쇄 공정 중에는 필연적으로 목표한 크기보다 작은 크기의 입자 즉, 미분이 발생한다. In general, when preparing a material using powder, it is necessary to appropriately control the amount of fine powder contained in the powder, depending on the intended use. For example, when preparing an active material powder used in the production of an electrode for a secondary battery, a crushing process is performed to crush and spheronize large particles into small pieces through a pulverization process in order to produce a powder having a desired particle size. The produced powders are mixed to produce homogenized powders suitable for use. However, during the milling process, particles of a smaller size than the target size, that is, fine powder are generated.
분체들을 혼합하여 균질화하는 공정을 수행할 때, 분체 중의 미분량을 그 사용 용도에 따라 적절히 제어할 필요가 있다. 종래에는 미분량 제어를 위해 싸이클론과 같은 별도의 미분 제어 장치를 공정 중에 설치하여 혼합 공정 후에 미분량을 제어하는 방식을 사용하였다. When performing the process of mixing and homogenizing powders, it is necessary to control the amount of fines in powder suitably according to the use purpose. Conventionally, for controlling the fine amount, a separate fine control device such as cyclone was installed in the process to control the fine amount after the mixing process.
그러나 이러한 종래의 방식은 관련 설비 설치를 위한 별도의 공간이 필요하며, 추가 공정 도입으로 인한 생산 효율이 저하되는 것을 피할 수 없었다. However, this conventional method requires a separate space for the installation of the associated equipment, it was inevitable to reduce the production efficiency due to the introduction of additional processes.

The parabolic air stream effectively introduces fine particles suspended in the upper portion of the mixing chamber 10 into the air stream to be discharged through the gas outlet 34. However, the air stream extending in the form of a parabola may be formed without depending on the inclined arrangement of the gas inlet 32 and the gas outlet 34. The operations of the gas introduction part 32 and the gas discharge part 34 are preferably performed simultaneously in synchronization. Therefore, the gas injection operation of the gas introduction part 32 and the gas discharge operation of the gas discharge part 34 are performed at the same time, so that the fine particles floating in the upper differential floating region inside the mixing chamber 10 can be more effectively removed. have. The amount of fines in the powder discharged to the outside of the mixing chamber 10 may be controlled according to the amount of fines floating in the upper portion inside the mixing chamber 10.
이하 본 발명에 따른 분체 흡입 및 미분 제어 장치의 바람직한 동작을 설명한다. Hereinafter, the preferred operation of the powder suction and fine powder control device according to the present invention.
본 발명에 따른 분체 흡입 및 미분 제어 장치에서는 먼저 교반수단(20)을 이루는 교반봉의 회전에 의해 교반 동작이 수행된다. In the powder inhalation and fine control apparatus according to the present invention, the stirring operation is first performed by the rotation of the stirring rod constituting the stirring means 20.
교반봉의 회전에 의해 활물질 분체가 유동하면서 서로 다른 크기의 입자 크기를 갖는 분체들이 고르게 섞이게 되는 데, 분체들은 교반봉의 회전에 의해 회전 유동과 상하 유동을 하면서 균질 상태가 되도록 고르게 섞이게 된다. As the active material powder flows by the rotation of the stirring rod, the powders having different particle sizes are mixed evenly. The powders are mixed evenly so as to be homogeneous while rotating and the vertical flow by the rotation of the stirring rod.
설정된 시간 동안 교반수단(20)이 동작하여 교반이 이루어진 후 교반수단(20)의 동작이 정지되면, 혼합 챔버(10) 내부에서 입자 크기가 큰 분체들은 가라앉고 입자 크기가 작은 미분들은 혼합 챔버(10) 내부의 상측 부분에 부유하는 상태가 형성된다. 이 상태로 시간이 경과되면 혼합 챔버(10) 내부에서 부유하던 미분이 가라앉게 된다. 본 발명에서 미분 제거부(30)의 동작 즉, 가스 도입부(32)에 의한 가스 분사 동작과 가스 배출부(34)에 의한 가스 배출 동작은 교반수단(20)이 정지된 후 입자 크기가 작은 미분들이 혼합 챔버(10) 내부 상측 미분 부유 영역에 부유하는 상태에서 수행된다.When the stirring means 20 is operated for a predetermined time and the stirring means 20 is stopped after the stirring is performed, the powders having a large particle size sink in the mixing chamber 10 and the fine powder having a small particle size is mixed with the mixing chamber ( 10) The floating state is formed in the upper part of the inside. After this time elapses, the fine powder floating in the mixing chamber 10 sinks. In the present invention, the operation of the fine powder removal unit 30, that is, the gas injection operation by the gas introduction unit 32 and the gas discharge operation by the gas discharge unit 34 are fine powder having a small particle size after the stirring means 20 is stopped. In the state of floating in the upper differential floating region inside the mixing chamber 10.
도 3 은 본 발명에 따른 분체 흡입 및 미분 제어 장치에서 미분 제거부의 작동을 설명하기 위한 단면도로서 일부 구성요소는 생략되어 도시되어 있다. Figure 3 is a cross-sectional view for explaining the operation of the fine powder removing unit in the powder suction and fine powder control apparatus according to the present invention, some components are omitted.
교반수단(20)의 동작이 정지된 후 즉시, 가스 도입부(32)를 통해 가스가 분사되고 가스 배출부(34)에 의해 가스 배출 동작이 이루어지면, 가스 도입부(32)와 가스 배출부(34) 사이에서는 분사된 가스가 이동하면서 가스 배출부(34)로 배출되는 기류가 형성된다. 이러한 기류를 타고 혼합 챔버(10) 내에 부유하는 미분들이 이동하면서 가스 배출부(34)를 통해 가스와 함께 배출 제거된다. Immediately after the operation of the stirring means 20 is stopped, when the gas is injected through the gas introduction part 32 and the gas discharge operation is performed by the gas discharge part 34, the gas introduction part 32 and the gas discharge part 34. ), An air stream discharged to the gas discharge part 34 is formed while the injected gas moves. The fine particles floating in the mixing chamber 10 in this airflow are discharged and removed together with the gas through the gas discharge part 34.
가스 도입부(32)와 가스 배출부(34) 사이에 포물선 기류가 형성되며 부유된 미분이 가라앉는 것이 방지되면서 가스 배출부(34)를 향해 형성된 가스의 기류를 타고 미분이 배출되는 것을 촉진하다. 가스 도입부(32)와 가스 배출부(34) 사이에 포물선 형태로 연장되는 기류가 형성되는 경우 제거되는 미분량의 제어가 보다 효과적으로 수행될 수 있다. A parabolic airflow is formed between the gas introduction part 32 and the gas discharge part 34, and the fine powder is discharged along the airflow of the gas formed toward the gas discharge part 34 while the suspended fine powder is prevented from sinking. When the airflow extending in the form of a parabola is formed between the gas inlet 32 and the gas outlet 34, the control of the amount of fines removed can be more effectively performed.
따라서 가스 도입부(32) 및 가스 배출부(34)는, 혼합 챔버(10) 내에서 미분들의 부유를 유지시키면서 미분들이 가스 흡입 기류를 따라 신속하게 이동하여 가스 배출부(34)를 통해 가스와 함께 배출 제거되도록 한다. Accordingly, the gas introduction part 32 and the gas discharge part 34 move together with the gas through the gas discharge part 34 while the fines move quickly along the gas intake air stream while maintaining the floating of the fine particles in the mixing chamber 10. Allow exhaust to be removed.
도 4 는 본 발명에 따른 분체 흡입 및 미분 제어 장치의 다른 실시예를 설명하기 위한 도면이다. 4 is a view for explaining another embodiment of the powder suction and fine control apparatus according to the present invention.

Referring to FIG. 4, the gas introduction part 320 and the gas discharge part 340 forming the differential removal part are installed at one side of the upper side and the other side of the upper side of the mixing chamber 100, and the stirring rod forming the stirring means 200 is the mixing chamber. It is arranged horizontally inside the 100 and the shape of the mixing chamber 100 is formed differently.
도 4 에 도시된 실시예에 의하면, 가스 도입부(320)는 혼합 챔버(100)의 상부 일측 측면에서 배치되어 가스를 분사하고, 가스 배출부(340)는 혼합 챔버(100)의 상부 타측 측면에서 배치되어 가스를 흡입한다. 도 4 에 도시된 실시예에서는 도 3 에 도시된 실시예와 같이 가스 도입부(320)와 가스 배출부(340) 사이에 포물선 형태의 기류가 형성되는 것을 도시하고 있으나, 이에 제한되지 않는다. 즉, 가스 도입부(320) 및 가스 배출부(340)가 서로 수평 방향으로 배치되어 미분 부유 영역을 관통하는 직선 형태의 기류가 형성될 수 있다. According to the embodiment shown in FIG. 4, the gas inlet 320 is disposed at one side of the upper side of the mixing chamber 100 to inject gas, and the gas outlet 340 is at the other side of the upper side of the mixing chamber 100. Disposed to inhale the gas. In FIG. 4, the parabolic airflow is formed between the gas introduction part 320 and the gas discharge part 340 as in the embodiment of FIG. 3, but is not limited thereto. That is, the gas inlet 320 and the gas outlet 340 may be disposed in a horizontal direction to form a straight air stream passing through the differential floating region.
도 4에서 보이는 바와 같이 도 1 내지 도 3 에 도시된 실시예에서 혼합 챔버의 형태에 대해 원통형의 상부 부분과 호퍼형의 하측 부분을 갖는 것으로 설명하였으나, 혼합 챔버는 다양한 형태가 사용될 수 있고, 혼합 챔버의 형태에 따라 교반수단 역시 다양한 형태가 사용 배치될 수 있다. As illustrated in FIG. 4, the embodiment shown in FIGS. 1 to 3 has been described as having a cylindrical upper portion and a hopper-shaped lower portion with respect to the shape of the mixing chamber. However, the mixing chamber may be used in various forms. Depending on the shape of the chamber, the stirring means may also be used in various forms.
본 발명의 실시예에 의하면 가스 도입부에 의한 가스 분사와 가스 배출부에 의한 가스 배출에 의해 미분이 제거되는 공정이 교반수단이 정지된 후에 이루어지는 것으로 설명하였으나, 가스 도입부 및 가스 배출부에 의한 미분 제거 공정은 교반수단의 동작과 함께 수행될 수 있다. 즉, 교반수단에 의해 교반이 이루어진 후, 교반수단이 정지하는 것이 아니라, 약하게 동작 예컨대 교반날개가 저속으로 회전하면서 미분이 부유하는 것을 도울 수 있다. According to the embodiment of the present invention, the process of removing the fine powder by the gas injection by the gas introduction unit and the gas discharge by the gas discharge unit is described as being performed after the stirring means is stopped, but the fine powder removal by the gas introduction unit and the gas discharge unit is explained. The process can be carried out with the operation of the stirring means. That is, after the stirring is performed by the stirring means, the stirring means is not stopped, but it is possible to help the floating of the fine powder while the action of the stirring blade is rotated at low speed.
본 발명에 의하면 가스 도입부 및 가스 배출부에 의한 미분 제거량은 가스 분사 및 가스 배출 시간 또는 횟수에 의해 조절될 수 있다. 바람직하게는 횟수에 의해 조절된다. According to the present invention, the amount of fine powder removed by the gas inlet and the gas outlet may be adjusted by the gas injection and the gas discharge time or frequency. It is preferably adjusted by the number of times.
예컨대, 1회 동작시 설정된 시간 동안 가스 도입부 및 가스 배출부가 작동되도록 설정된 상태에서, 가스 도입부의 동작 횟수를 증가시킴에 따라 혼합 챔버 내에서 제거되는 미분량이 증가한다. 가스 도입부와 가스 배출부의 동작은 동기화되어 있다. 따라서 본 발명에 의하면 가스 도입부의 동작 횟수를 조절하여 제거되는 미분의 양을 제어할 수 있고, 제거되는 미분량의 제어는 분체 내의 포함되는 미분량을 제어하는 것이 된다. For example, in a state where the gas inlet and the gas outlet are set to be operated for a set time in one operation, the amount of fines removed in the mixing chamber increases as the number of operations of the gas inlet increases. The operation of the gas inlet and gas outlet is synchronized. Therefore, according to the present invention, the amount of fine powder to be removed can be controlled by adjusting the number of operations of the gas introduction unit, and the control of the fine powder to be removed is to control the fine powder contained in the powder.
본 발명에 의하면 상기한 과정을 통해 균질화된 분체 내에 존재하는 미분량이 제어될 수 있는 데, 본 발명에 의하면 별도의 미분 제거 장치를 설치하지 않고, 분체 균질화를 위한 혼합과 미분량 제어가 하나의 장치 내에서 이루어질 수 있는 데, 이를 통해 공정 시간의 단축뿐만 아니라 분체를 별도의 미분 제거 장치로 이송하는 과정에서 발생하는 분체 손실도 방지할 수 있는 장점이 있다. According to the present invention, the amount of fine powder present in the homogenized powder can be controlled through the above process. According to the present invention, mixing and fine powder control for powder homogenization are performed without installing a separate fine powder removing device. It can be made in the device, through which there is an advantage that can not only reduce the process time, but also prevent the powder loss caused in the process of transferring the powder to a separate fine powder removal device.
이상에서는 본 발명의 바람직한 실시예에 대하여 설명하였으나, 본 발명은 상기한 실시예의 기재에 한정되지 않으며, 본 발명의 특허청구범위의 기재를 벗어나지 않는 한 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의한 다양한 변형 실시 또한 본 발명의 보호범위 내에 있는 것으로 해석되어야 한다.Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the description of the embodiments described above, and does not depart from the description of the claims of the present invention.
