Description

Hybrid flange portion and sublimation purifying apparatus having the same

The present invention relates to a hybrid flange portion and a sublimation purification device having the same, and more specifically, to a hybrid flange portion capable of selectively connecting multiple pumps to one flange and a sublimation purification device having the same.

Typically, sublimation purification equipment is used in the sublimation purification process, which is a process for removing impurities from low-molecular-weight organic substances that can be used as light emitters or transporters in organic EL or OLED devices.

Conventionally, much research has been conducted on the development of an organic sublimation purification device to purify organic substances with high purity by removing impurities through this process.

Referring to Republic of Korea Patent No. 10-1124687, a conventionally developed organic sublimation purification device is described as follows.

Conventionally developed organic sublimation purification devices include a purification unit 10 that sublimates and collects organic substances from purification objects, and a vacuum installed on one side of the purification unit 10 to selectively control the vacuum state inside the purification unit 10. It includes a unit 20 and a trap unit 30 that blocks sublimated organic substances from moving to a specific area.

The purification object is placed inside the purification unit, and as it is heated at high temperature, the organic matter sublimates in the purification object, and the sublimated organic matter is collected.

Here, the purification unit 10 is equipped with a separate heating unit 11 to control the internal temperature and sublimate the organic substances contained in the purification object.

The vacuum unit 20 is connected to one side of the purification unit 10 and controls the internal vacuum state, and is equipped with a separate vacuum pump 21 to control the inside of the purification unit 10 to a high vacuum state. .

Meanwhile, in a high vacuum state, the distribution of gas inside becomes extremely small, and thus there is no gas flow.

Accordingly, in the purification unit 10, which is placed in a high vacuum state by the vacuum unit 20, the sublimated organic substances move freely and are collected in the collection area.

The trap unit 30 is a component that blocks organic substances sublimated in the purification unit 10 from moving to the vacuum pump 21, and blocks freely moving gaseous organic substances by continuously circulating a separate refrigerant. .

Specifically, the trap unit 30 blocks gaseous organic matter using a general refrigerant, and is equipped with a refrigerant such as liquid nitrogen or dry ice to exchange heat with gaseous organic matter or impurities to condense them. By allowing the impurities to be deposited in the trap unit 30, sublimated organic substances are prevented from moving to the vacuum pump 21.

However, this configuration not only increases the volume of the trap unit but also makes the structure very complicated, making cleaning, maintenance, and repair work inside the chamber very inconvenient.

In addition, there was a problem that safety issues had to be specially managed because the refrigerant had to be continuously charged and a major accident could occur if the ultra-low temperature refrigerant leaked.

The purpose of the present invention is to arrange the area connected to the tube, the trap unit area, and the vacuum pumping area side by side in one flange body, and provide a coupler of the same size for opening and closing each area and connecting the pump.

Then, the sublimated organic matter is collected by attaching to the outer surfaces of the above-described collection members.

Accordingly, the purified product from which gaseous organic substances have been removed from the purification object heated above a certain level flows from the second region to the third region. This is achieved by driving a vacuum pump.

Here, the fan of the blowing means disposed inside the case is driven under the control of the control unit.

The cooling rod is made of stainless steel.

Here, the length of the heating member is shorter than the length of the cooling rod.

Accordingly, one end of the cooling rod is exposed to the outside at a certain distance from the end of the heating member.

A collection area is formed at one end of the cooling rod and is spaced a certain distance apart.

The heating member receives current through a separate current provider and is heated to a certain temperature.

Additionally, a flow path is formed inside the cooling rod.

The flow path is connected to the cooling water supply unit through a tube.

The coolant supply unit supplies coolant having a predetermined cooling temperature to the flow path of the cooling rod.

Accordingly, the cooling rod is cooled to a certain cooling temperature.

The second collection unit configured as above is disposed in the first area of the flange body described above.

The second collection unit may be fixed to a separate bracket formed in the first area.

Accordingly, the purification object heated inside the inner tube, including the purified material and vaporized organic matter, flows inside the outer tube by the vacuum of the vacuum pump and flows into the first region through the connector.

And the vaporized organic matter may stick to the collection area where the temperature difference occurs.

Accordingly, organic matter vaporized in the first area may stick to the collection area and be removed primarily.

However, residual organic matter that is not collected in the collection area of the cooling rod in the first area may flow to the second area as described above and be collected secondarily by the first collection unit.

That is, in the present invention, vaporized organic substances generated in the process of heating the purification object in the inner tube of the heating unit are sequentially removed by the first and second collection units, and the purified substances flowing into the third area are relatively collected in multiple stages. Purity can be increased above a certain level compared to the case where this is not done.

The present invention is not limited to the specific preferred embodiments described above, and various modifications can be made by anyone skilled in the art without departing from the gist of the invention as claimed in the claims. Of course, such changes are within the scope of the claims.
