Through this configuration, the pair of support shafts according to the present invention are rotated in association with the rotation of the rotation shaft.

Each stirring blade installed at each end of the pair of support shafts is also rotated in the outer region of the other end of the inner tube, and the purified object transferred and discharged through the pressure feeding of the inner air transfer screw of the inner tube is removed from the space outside the other end of the tube. It can be stirred in

Although not shown in the drawings, the sublimation purification apparatus according to the present invention has a collecting unit.

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

The first collecting unit according to the present invention is composed of the trap unit disposed in the second region inside the flange portion described above. Hereinafter, the trap unit will be described as a first collecting unit.

The configuration of the first collecting unit will be described.

The first collecting unit includes a first collecting unit body having a cylindrical shape having an open top, a ring body installed on the upper end of the first collecting 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 region formed inside the flange part body through the first upper connection hole formed at the upper end of the flange part body.

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

The thermoelectric module has a plurality of collection members and a current providing device for providing current to the plurality of collection members.

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

Preferably, the cooling surface of each of the plurality of collecting members is an inner surface, and the heating surface is preferably an outer surface.

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

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

Here, each of the plurality of collecting members is bent in an 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.

An 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 end 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 have a length corresponding to the vertical length of the first collecting unit body.

In addition, the upper end members bent at the upper end of each of the lower end members extend to the central position of the ring body so that the ends of each of the upper end 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.

At the upper end of the central bar, a rectangular box-shaped case with an open upper end is disposed.

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 lower surface of the case.

4 The plurality of discharge holes are formed by being perforated at a plurality of positions along a direction radiating from the central position of the case.

In addition, the plurality of discharge holes are formed such that the inner diameter is gradually expanded along a direction radiating from the central position of the case.

In addition, the area of the bottom surface of the case may form an area included in the opening area of the ring body.

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

The blowing means includes a fan and a fan module for rotating the fan. The fan module rotates the fan under the control of the controller.

Referring to the above configuration, the sublimated organic material 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. .

And the sublimated organic matter is collected by being attached to the outer surface of the collecting members.

Accordingly, the purified material from which the gaseous organic matter is removed from the purified object heated to a certain level or more flows from the second region to the third region. This is done by driving the vacuum pump.

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

The heat generated in a state in which the object to be purified is heated according to the driving of the fan may be discharged through a space between upper members constituting the plurality of collecting members.

In addition, a plurality of discharge holes are formed in the case, and the heat may be discharged to an upper portion of the case through the plurality of discharge holes.

In addition, the gaseous organic matter generated by the heated sublimation object may be collected by a plurality of collecting members as described above.

Next, the configuration of the second collecting unit according to the present invention will be described.

The second collecting unit according to the present invention has a cooling rod formed of a metal having a predetermined length, and a heating member disposed to surround the outer periphery of the cooling rod.

The cooling rod is formed of a stainless material.

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

Accordingly, one end of the cooling rod is exposed to the outside while being spaced apart from the end of the heating member by a predetermined distance.

At one end of the cooling rod, a collecting area spaced apart from the predetermined distance is formed.

The heating member is heated to a predetermined temperature by receiving a current through a separate current provider.

In addition, a flow path is formed inside the cooling rod.

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

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

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

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

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

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

In addition, the vaporized organic material may stick to the collecting area where the temperature difference is generated.

Accordingly, the organic matter vaporized in the first region may adhere to the collecting region and be primarily removed.

However, residual organic matter not collected in the collecting region of the cooling rod in the first region may flow to the second region as described above, and secondary collection may be achieved by the first collecting unit.

That is, according to the present invention, vaporized organic matter generated in the process of heating the object to be purified in the inner tube of the heating unit is sequentially removed by the first and second collecting units, and the purified material flowing into the third region is collected in multiple stages relatively. Compared to the case where it is not made, the purity may be increased to a certain level or more.

The present invention is not limited to the specific preferred embodiments described above, and without departing from the gist of the present invention as claimed in the claims, anyone with ordinary skill in the art to which the invention pertains can implement various modifications Of course, such modifications are intended to be within the scope of the claims.
