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.

Although not shown in the drawing, the sublimation purification device according to the present invention has a collection unit.

The collection unit according to the present invention has a first collection unit and a second collection unit.

The first collecting part according to the present invention consists of the trap unit disposed in the second area inside the above-described flange part. Hereinafter, the trap unit will be described and referred to as the first collection unit.

The configuration of the first collection unit will be described.

The first collection unit has a cylindrical first collection unit body with an open top, a ring body installed on the top of the first collection unit body, a thermoelectric module, and a blowing means.

The ring body is installed on the upper edge of the first collecting part, and can be inserted and fixed into the second area formed inside the flange part body through the first upper connection hole formed at the top of the flange part body described above.

Here, the first collection unit body is disposed in the second area and exposed upward through the opening of the ring body.

The thermoelectric module has a plurality of collecting members and a current providing device that provides current to the plurality of collecting members.

One surface of each of the plurality of collection members forms a cooling surface and the other surface forms a heating surface.

Preferably, the cooling surface of each of the plurality of collection members is the inner surface, and the heating surface is the outer surface.

The current providing device provides current to the plurality of collecting members to form a constant cooling temperature on the cooling surface and a certain heating temperature on the heating surface.

Accordingly, a temperature difference occurs between the cooling surface and the heating surface of the plurality of collecting members.

Here, each of the plurality of collection members is bent into a shape. That is, each of the plurality of collecting members has a lower member having a first length and an upper member bent at the upper end of the lower member.

The angle between the lower member and the upper member forms an obtuse angle.

The length of the lower member is formed to be longer than the length of the upper member by a predetermined length.

The lower members of each of the plurality of collecting members are disposed near the inner wall of the first collecting unit body and are arranged at regular intervals along the circumferential direction of the first collecting unit body.

Here, the length of the lower members may be formed to correspond to the upper and lower length of the first collection unit body.

In addition, the upper members bent at the upper ends of each of the lower members extend to the center of the ring body, so that the ends of the upper members are connected to each other.

A central bar is installed at a central position where the ends of each of the upper members are connected to each other.

A rectangular box-shaped case with an open top is disposed at the top of the center rod.

The upper end of the central rod is connected to the lower center of the case.

A plurality of discharge holes are formed in the bottom of the case.

4The plurality of discharge holes are formed by being drilled in a plurality of positions along a direction radiating from the center position of the case.

Additionally, the plurality of discharge holes are formed so that their inner diameters gradually expand along a direction radiating from the center position of the case.

Additionally, the bottom area of the case may be included in the opening area of the ring body.

The blowing means is disposed in the inner space of the case.

The blowing means has a fan and a fan module that rotates the fan. The fan module rotates the fan under the control of a control unit.

Referring to the above configuration, the organic matter sublimated in the outer tube according to the present invention flows from the first region to the second region through the first lower connection hole formed in the flange body, the inside of the flow box, and the second lower connection hole. .

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 heat generated when the purification object is heated as the fan is driven may be discharged through the space between the upper members of the plurality of collection members.

In addition, a plurality of discharge holes are formed in the case, and the hot air may be discharged to the top of the case through the plurality of discharge holes.

And gaseous organic matter generated by the heated sublimation object can be collected by a plurality of collecting members as described above.

The following describes the configuration of the second collection unit according to the present invention.

The second collection unit according to the present invention has a cooling rod made of metal with a certain length, and a heating member disposed to surround the outer periphery of the cooling rod.

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.
