Description

Vertical continuous vacuum purifier

[0001] The present invention relates to a vacuum purifier that recovers purified substances by sublimating or vaporizing materials in a vacuum, and more specifically, to a vertical continuous vacuum purifier that shortens the purification processing time and enables high-purity purification.

[0002] In general, the purity of organic materials is a very important factor when used as electronic materials.

[0003] This is because even minute amounts of impurities contained in organic materials can often have a fatal impact on the performance of electronic devices.

[0004] For this reason, high-purity purification is recognized as an essential requirement in the development of various organic materials currently used in electronic products, and a vacuum purification method is widely known in which organic materials are heated in a sublimation device capable of controlling the temperature gradient to separate them from impurities with different sublimation or vaporization points.

[0005] This vacuum purification method is a purely physical method and does not use auxiliary reagents or other chemical methods, so it has the advantages of no contamination by the sample and a high separation rate.

[0006] As illustrated in Fig. 1, a conventional vacuum purifier that performs purification according to the above-described vacuum purification method is composed of an inner tube (1), an outer tube (2) that surrounds the outside of the inner tube (1), a boat (3) that is placed inside the inner tube (1) and contains an organic material to be purified, a heater unit (5) that surrounds one side of the outer tube (2), and a vacuum pump (not illustrated) connected to the outer tube (2).

[0007] Accordingly, when the vacuum pump and heater section (5) are operated, a temperature gradient from high temperature to low temperature is formed throughout the outer tube (2) under a vacuum state, and when the temperature of the purification tube (3) becomes higher than the sublimation point or vaporization point of the organic material to be purified, the organic material sublimates and becomes a gaseous molecule, and the vaporized molecules diffuse into the inner tube (1) in the direction of increasing entropy.

[0008] At this time, if the temperature of the inner tube (1) is set differently for each section, molecules with high kinetic energy collide with the inner wall surface of the inner tube (1) with a low temperature, and since the gas density in the boat (3) is high and the gas density in the inner tube (1) with a relatively low temperature is low, a pressure difference occurs, causing continuous gas movement.

[0009] That is, the gas molecules of the organic material are transferred back to a solid or liquid phase in a section of the inner tube (1) having a temperature below the sublimation point or vaporization point during the movement process, and exist on the inner wall surface of the inner tube (1).

[0010] Afterwards, the worker cools the inner tube (1), disassembles it, and scrapes out and recovers the purified organic material (10).

[0011] However, since these conventional vacuum purifiers must go through a discontinuous multi-step process of preheating, sublimating, cooling the heater section (5), dismantling the inner tube (1), scraping out and recovering the purified material, movement is required for each step, and during movement, exposure to the atmosphere and various pollutants occurs, which causes a problem in that it affects the purity of the organic material.

[0012] In addition, conventional vacuum purifiers have many problems such as a greatly reduced thermal efficiency due to the multi-step process described above, a long sublimation purification treatment time, a reduced productivity, increased energy consumption, a high possibility of quality defects due to deterioration of organic materials when exposed to heat for a long time, and the need to clean the purification tube (3). Therefore, improvement is required.

[0013] The present invention has been devised to solve the above-mentioned problems, and its purpose is to provide a vertical continuous vacuum purifier capable of shortening the purification processing time and achieving high-purity purification by not going through a multi-step process.

[0014] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0015] In order to achieve the above object, the vertical continuous vacuum purifier of the present invention includes a vertical vacuum tube, a rotation unit for rotating the vertical vacuum tube, a material supply unit installed at an upper portion of the vertical vacuum tube for injecting material into the interior of the vertical vacuum tube, a heater unit installed at the vertical vacuum tube for heating the material to sublimate or vaporize, a blade for removing purified material that has vaporized or sublimated and adhered to the inner wall of the vertical vacuum tube, a recovery unit installed at a lower portion of the vertical vacuum tube for collecting purified material removed by the blade, and a control unit for controlling the temperature of the heater unit and the vacuum level within the vertical vacuum tube.

[0016] In addition, the vertical vacuum tube is formed to have a height greater than the inner diameter, the refined materials removed by the blade are recovered to the recovery unit by gravity, the vertical vacuum tube is installed to be inclined between 10 and 90 degrees with respect to the horizontal plane, and the distance between the inner wall surface of the vertical vacuum tube and the blade may be 3 cm or less.

[0017] In addition, the refined material attached to the inner wall surface of the vertical vacuum tube can be removed by friction with the blade while the vertical vacuum tube rotates while the blade is stationary, or can be removed by friction with the blade while the blade rotates inside the vertical vacuum tube while the vertical vacuum tube is stationary.

[0018] In addition, a first connecting member that rotatably connects the vertical vacuum tube may be installed between the vertical vacuum tube and the material supply unit, and a second connecting member that rotatably connects the vertical vacuum tube may be installed between the vertical vacuum tube and the recovery unit.

[0019] In this case, a vacuum valve may be installed in the second connecting member to collect the crystallized material stored in the recovery unit while maintaining a vacuum state within the vertical vacuum tube.

[0020] Meanwhile, the vertical vacuum tube may be equipped with a quartz tube and a first boat installed inside the quartz tube to receive material injected from a material supply unit.

[0021] In addition, the rotation unit may include a support frame installed on the outside of the vertical vacuum tube, a vertical shaft installed on the support frame in parallel with the vertical vacuum tube, a driven gear installed on the outer surface of the vertical vacuum tube, a driving gear installed on the vertical shaft to mesh with the driven gear, and a first driving motor installed on the support frame to provide rotational force to the driving gear.

[0022] In addition, the material supply unit may be equipped with a material storage tank in which materials are stored, and a material injection unit that receives materials from the material storage tank under a vacuum state and injects them into the interior of a vertical vacuum tube.

[0023] In this case, the material injection unit may be provided with a first chamber, a hopper installed inside the first chamber so as to be connected to the material storage tank, a material supply pipe vertically extended from the lower portion of the hopper and inserted into the inside of a vertical vacuum tube, and a spiral screw that rotates inside the material supply pipe to quantitatively inject the material in the hopper into the inside of the vertical vacuum tube.

[0024] Meanwhile, the blade may be positioned above and below the first boat and may be provided with a blade body that scrapes off refined material stuck to the inner wall surface of the rotating quartz tube when the quartz tube rotates and removes it from the inner wall surface of the quartz tube.

[0025] In addition, the blade may be provided with a first ball screw installed vertically on the first connecting member so as to be positioned above and below the first boat, and a blade body installed to ascend and descend along the first ball screw, and to scrape off refined materials stuck to the inner wall surface of the rotating quartz tube when the quartz tube rotates and remove them from the inner wall surface of the quartz tube.

[0026] In addition, a cooling unit may be further provided on the outside of the vertical vacuum tube to be positioned above the heater section and to locally lower the temperature of a specific area of ​​the vertical vacuum tube.

[0027] Additionally, the vertical vacuum tube, the rotation unit, the heater unit, and the blade may be installed in multiple stages as a set.

[0028] Meanwhile, the heater unit may be any one of an electric heater, an infrared heater, and an electromagnetic induction heater.

[0029] In addition, a vacuum pump may be connected to the material supply unit and the recovery unit, and a low-temperature trap may be provided between the vacuum pump and the vertical vacuum pipe, and between the vacuum pump and the material supply unit, respectively.

[0030] The vertical continuous vacuum purifier of the present invention configured as described above has the effect of preventing loss and contamination due to movement of materials for collecting materials after purification and significantly shortening the working time, as compared to the conventional method where the supply and sublimation of materials and the collection of purified materials are continuously performed in a vertical direction in a multi-stage manner in a horizontal manner.

[0031] In addition, the present invention allows the material to be heated uniformly and in a short period of time through a heater installed in a vertical vacuum tube, thereby rapidly sublimating or vaporizing, so that unlike the conventional method, energy consumption can be minimized, and since the material is not exposed to heat for a long period of time, quality deterioration and deterioration can be prevented, and there is no need to clean the vertical vacuum tube.

[0032] In addition, the present invention can more precisely control the temperature corresponding to the sublimation condition of a material by selectively using various heat energy sources such as an electromagnetic wave heater, an electromagnetic induction heater, an electric heater, or an infrared heater according to the characteristics of the material, thereby enabling ultra-high purity purification.

[0033] The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

[0062] Hereinafter, in describing an embodiment of the present invention in detail with reference to the drawings, the same reference numerals are used for the same components, and for the sake of clarity, only different parts are mainly described without duplication as much as possible.

[0063] As illustrated in FIGS. 1 to 5, the vertical continuous vacuum purifier of the present invention includes a vertical vacuum tube (100), a rotation unit (200) that rotates the vertical vacuum tube (100), a material supply unit (300) installed on the upper portion of the vertical vacuum tube (100), a heater unit (400) that heats and sublimates a material injected into the vertical vacuum tube (100), a control unit (not illustrated) that controls the temperature of the heater unit (400) and the vacuum level within the vertical vacuum tube (100), a blade (500) that removes a purified material stuck to the inner wall of the vertical vacuum tube (100), and a recovery unit (600) that collects a crystallized material removed by the blade (500).

[0064] The above material may be an organic material or an inorganic material.

[0065] A vacuum pump (not shown) that maintains a vacuum state is connected to the material supply unit (300) and recovery unit (600). The operation of the vacuum pump is controlled through a control unit.

[0066] In this case, a low-temperature trap (700) may be installed between the vacuum pump, the vertical vacuum pipe (100), and the material supply unit (300) to capture materials or impurities moving to the vacuum pump.

[0067] Meanwhile, a first connecting member (800) that rotatably connects the vertical vacuum tube (100) while maintaining a vacuum state may be installed between the vertical vacuum tube (100) and the material supply unit (300).

[0068] In addition, a second connecting member (900) that rotatably connects the vertical vacuum tube (100) while maintaining a vacuum state may be installed between the vertical vacuum tube (100) and the recovery unit (600).

[0069] A vacuum valve (910) may be installed in the second connecting member (900) to collect the crystallized material stored in the recovery unit (600) while maintaining a vacuum state within the vertical vacuum tube (100). The operation of the vacuum valve (910) is controlled by a control unit.

[0070] The above vacuum valve (910) is normally kept open, but is closed just before collecting materials from the recovery unit (600) to maintain a vacuum state within the vertical vacuum tube (100). After the collection of materials from the recovery unit (600) is completed and the recovery unit (600) is restored to a vacuum state, the vacuum valve (910) is opened again.

[0071] Meanwhile, the vertical vacuum tube (100) may be equipped with a quartz tube (110) whose upper end is rotatably connected to a first connecting member (800) and whose lower end is rotatably connected to a second connecting member (900), and a first boat (120) installed inside the quartz tube (110).

[0072] The above first boat (120) receives material injected from the material supply unit (300).

[0073] The above first boat (120) may be provided with a pair of vertical guide rods (121) installed in the first connecting member (800) and inserted into the quartz tube (110), and a stand (122) fixed to the lower end of the vertical guide rods (121) to hold the first boat (120) in a horizontal position.

[0074] Meanwhile, the rotation unit (200) may be provided with a support frame (210) installed outside a vertical vacuum tube (100), a vertical shaft (220) installed parallel to the vertical vacuum tube (100) on the support frame (210), a driven gear (230) installed on the outer surface of the vertical vacuum tube (100), a drive gear (240) installed on the vertical shaft (220) to mesh with the driven gear (230), and a first drive motor (250) installed on the support frame (210) to provide rotational force to the drive gear (240). The operation of the rotation unit (200) is controlled through a control unit.

[0075] Therefore, when the first drive motor (250) is driven, the drive gear (240) and the driven gear (230) rotate, causing the quartz tube (110) to rotate in place.

[0076] The above material supply unit (300) may be equipped with a material storage tank (310) in which materials are stored, and a material injection unit (320) that receives materials from the material storage tank (310) under a vacuum state and injects them into the vertical vacuum tube (100). The operation of the material supply unit (300) is controlled by a control unit.

[0077] The above material injection unit (320) is connected to a vacuum pump and maintains a vacuum state together with a vertical vacuum tube (100).

[0078] In this case, the material injection unit (320) is installed on the upper part of the first connecting member (800) and may be provided with a first chamber (321) connected to a vacuum pump.

[0079] A hopper (322) is installed inside the first chamber (321). The hopper (322) is connected to a material storage tank (310) and continuously receives materials from the material storage tank (310).

[0080] A material supply pipe (323) is formed to extend vertically at the bottom of the above hopper (322). The material supply pipe (323) penetrates the first connecting member (800) and is inserted into the vertical vacuum tube (100).

[0081] Meanwhile, an observation window may be formed in the first chamber (321) so that a worker can visually observe the material supply status from the outside.

[0082] In addition, a spiral screw (324) for quantitatively injecting material in the hopper (322) into the vertical vacuum tube (100) can be installed inside the material supply pipe (323).

[0083] The above spiral screw (324) is connected to the rotational axis of the second driving motor (325) installed on the upper part of the first chamber (321) and receives rotational force.

[0084] Accordingly, when the spiral screw (324) rotates, the material inside the hopper (322) descends along the spiral and is injected into the interior of the vertical vacuum tube (100). Therefore, by adjusting the rotational speed of the spiral screw (324), the amount of material injected can be precisely controlled.

[0085] Meanwhile, the heater unit (400) is installed on the outside or inside of the vertical vacuum tube (100) and directly or indirectly heats and sublimates the material injected into the vertical vacuum tube (100). The operation of the heater unit (400) is controlled by a control unit.

[0086] In this case, the heater unit (400) can be configured to selectively use various types of heat sources, such as an electric heater, an infrared heater, an electromagnetic induction heater, and an electromagnetic wave heater, depending on the material, to enable efficient ultra-high purity purification.

[0087] The sublimated material molecules move upward toward the first chamber (321) connected to the vacuum pump, and as the distance from the heater unit (400) increases, they cool and adhere to the inner wall surface of the quartz tube (110) in a crystallized state.

[0088] Accordingly, the present invention can minimize energy consumption and integrate several post-processes for collecting refined materials, thereby reducing loss due to movement of materials and reducing working time, and can also prevent materials from being exposed to air and contaminated by various sources of contamination during movement, and can also prevent quality deterioration and degradation by preventing the materials from being exposed to heat for a long period of time.

[0089] Meanwhile, the blade (500) is configured to remove the refined material stuck to the inner wall of the vertical vacuum tube (100).

[0090] In this case, the above blade (500) may be provided with a blade body (520) positioned above and below the first boat (120) to remove the refined material stuck to the inner wall of the vertical vacuum tube (100).

[0091] Meanwhile, the blade (500) may be installed in a fixed position above and below the first boat (120), or may be configured to be raised and lowered.

[0092] In the latter case, the operation of the blade (500) is controlled by a control unit. In addition, the blade (500) is provided with a first ball screw (510) installed vertically on the first connecting member (800) so as to be positioned above and below the first boat (120). The blade body (520) moves up and down along the first ball screw (510).

[0093] Such a blade body (520) is installed in close contact with the inner surface of the quartz tube (110), and when the quartz tube (110) rotates, it scrapes off the refined material stuck to the inner wall surface of the rotating quartz tube (110) and removes it from the inner wall surface of the quartz tube (110).

[0094] Although not shown, the blade (500) may be configured to rotate inside the vertical vacuum tube (100). In this case, even if the quartz tube (110) does not rotate, the blade (500) alone rotates to scrape off the refined material stuck to the inner wall surface of the quartz tube (110) and remove it from the inner wall surface of the quartz tube (110).

[0095] The above recovery unit (600) is installed at the bottom of the vertical vacuum tube (100) and collects the crystallized material removed by the blade (500) that falls freely by gravity.

[0096] In this case, the recovery unit (600) may be equipped with a second chamber (610) installed at the bottom of the second connecting member (900), and a second boat (620) installed inside the second chamber (610) to contain the crystallized material removed by the blade (500).

[0097] The second chamber (610) is provided with an opening (630) through which a second boat (620) can be withdrawn, and an observation window (640) may be formed to observe the state of collection of refined material falling from the second boat (620).

[0098] Although not shown, the second boat (620) may further be equipped with a crushing device capable of crushing the collected crystallized material.

[0099] In addition, although not shown, a cooling unit may be further provided on the outside of the vertical vacuum tube (100) to be positioned above or below the heater section (400) and to locally lower the temperature of a specific area of ​​the vertical vacuum tube (100).

[0100] The heater unit (400) installed on the outside of the vertical vacuum tube (100) can be installed so as to be able to be raised or lowered on the support frame (210), and in this case, the operation is controlled through the control unit.

[0101] In addition, when the sublimated material is formed in a solid or liquid form on the inner wall surface of the quartz tube (110), collection is possible using a blade (500).

[0102] In particular, when the sublimated material is formed as a liquid on the inner wall surface of the quartz tube (110), it becomes solid by the cooling unit, and at this time, the purified material can be collected by removing it from the inner wall surface of the quartz tube (110) using the blade (500).

[0103] Meanwhile, it is preferable that the vertical vacuum tube (100) be formed with a height greater than the inner diameter so that a large amount of refined materials can adhere to it.

[0104] In addition, it is preferable that the vertical vacuum tube (100) be installed at an angle of 10 to 90° with respect to the horizontal plane so that the refined materials removed by the blade (500) can be easily recovered to the recovery unit (600) by gravity.

[0105] In addition, in order to increase the removal and collection rate of refined materials, it is preferable that the distance between the inner wall surface of the vertical vacuum tube (100) and the blade (500) be formed to be 3 cm or less.

[0106] The vertical continuous vacuum purifier of the present invention configured as described above operates as follows.

[0107] First, when the quartz tube (110), material injection unit (320), and recovery unit (600) are brought into a vacuum state through a vacuum pump, the material is transferred from the material storage tank (310) to the hopper (322) of the material injection unit (320).

[0108] When the material is transferred to the hopper (322), the first driving motor (250) starts to operate and the spiral screw (324) starts to rotate, and the material in the hopper (322) descends along the rotating spiral screw (324) along the material supply pipe (323) and is quantitatively discharged and placed in the first boat (120) installed inside the quartz tube (110).

[0109] And, as the heater unit (400) operates, the material contained in the first boat (120) begins to heat.

[0110] As a result, the light materials contained in the material fly further and accumulate in the low temperature trap (700), resulting in separation of the desired material.

[0111] The material refined in this way rises along the quartz tube (110) in a gaseous molecular state and gradually cools, becoming attached to the inner wall surface of the quartz tube (110) in a crystallized state over a certain section.

[0112] And, when the refined material is attached to the inner wall surface of the quartz tube (110) in a crystallized state, the quartz tube (110) rotates by the second driving motor (325).

[0113] As the quartz tube (110) rotates, the refined materials stuck to the inner wall surface of the quartz tube (110) are wiped off by the blade (500) and fall from the inner wall surface of the quartz tube (110) to be collected in the second boat (620) of the recovery unit (600).

[0114] At this time, the crystallization temperature varies depending on the type of material to be purified, and as a result, the height at which it adheres to the inner wall surface of the quartz tube (110) also varies.

[0115] In this case, the worker can easily and conveniently remove all of the refined material by driving the first ball screw (510) to raise or lower the position of the blade body (520).

[0116] When the removal of the refined material is complete, the worker stops the second drive motor (325) to stop the rotation of the quartz tube (110).

[0117] When the rotation of the quartz tube (110) stops, the worker closes the vacuum valve (910) and opens the second chamber (610) to collect the purified material collected in the second boat (620).

[0118] Then, the second chamber (610) is closed and a vacuum state is created, and when the vacuum state is reached, the vacuum valve (910) is opened to prepare for the next operation.

[0119] In this way, the present invention can not only significantly shorten the working time but also improve workability because the supply of materials, sublimation, and collection of refined materials are continuously performed without stopping the work.

[0120] As shown in Fig. 6, as another embodiment of the present invention, the vertical vacuum tube (100), the rotation unit (200), the heater unit (400), and the blade (500) may be installed in multiple stages as a set.

[0121] At this time, a third connecting member (850, 950) is installed at the top and bottom of each vertical vacuum tube (100) to rotatably connect adjacent vertical vacuum tubes (100) in a vacuum state.

[0122] In this case, the refined materials stuck to the upper vertical vacuum tube (100) are collected by the first boat (120) of the vertical vacuum tube (100) installed at the bottom.

[0123] Therefore, by sublimating the material to be purified through multiple stages, it is possible to produce ultra-pure purified material.

[0124] As described above, the present invention is configured to cause a purified material to be collected in a vertical vacuum tube (100) in order to cause a continuous vacuum purification process to occur, to cause the purified material stuck to the inner wall surface of the vertical vacuum tube (100) to be detached through friction of a blade (500), and to allow the detached purified material to be easily and conveniently collected through gravity.

[0125] Above, the preferred embodiments of the present invention have been illustrated and described with reference to the drawings, but various modifications and changes can be made without departing from the spirit or scope of the present invention as defined by the following claims, and this should also be included in the scope of the present invention.
