Description

Moisture Centrifugal Dryer

[0001] The present invention relates to a moisture centrifugal dryer, and more particularly, to a moisture centrifugal dryer that is mounted on an air compressor and can remove moisture contained in compressed air.

[0002] In general, air compressors are used in all industrial processes such as semiconductor and chemical processes, medical equipment, and environmental equipment.

[0003] As an essential power source for the class, it has the advantages of ease of use, ease of storage, and safety, making it suitable for use in each production plant.

[0004] Compressed air is mostly used in the West, and in terms of its ease of handling, it is used in all the industries mentioned above as well as in the mechanical engineering, civil engineering, and other industries.

[0005] It is also applied to all industries that use machine tools, as well as various processes such as chemical industries and steel mills.

[0006] An air compressor like this is composed of a head section that generates compressed air and an air tank in which the compressed air generated in the head section is stored.

[0007] Meanwhile, the air compressor compresses air, cools the compressed high-temperature air, and then stores it in an air tank.

[0008] At this time, water is generated during the process of cooling the compressed air, and compressed air containing moisture is stored inside the air tank.

[0009] However, in this case, there was a problem that the inside of the air tank corroded, rust was generated, and the compressed air stored inside the air tank was contaminated.

[0010] In particular, for air compressors used in facilities that require thorough hygiene, such as dental clinics, it is very important to produce clean compressed air with moisture removed.

[0011] If compressed air containing moisture is stored in the air tank and becomes contaminated, there is a problem in which the contaminated compressed air is sprayed into the patient's mouth during treatment, causing harm to the patient's health.

[0012] In addition, since compressed air contains a large amount of moisture, there was a problem that the sprayed area was not completely dry during treatment, which reduced the bonding strength of the restoration.

[0013] In addition, dental equipment is operated by pneumatic pressure, and if compressed air containing moisture is supplied to the inside of the dental equipment, there is a problem that moisture will seep into the inside of the equipment, reducing the durability of the equipment or causing the equipment to break down.

[0014] Meanwhile, an air compressor equipped with a dryer was developed to solve the above-mentioned problems.

[0015] The dryer is placed between the head and the air tank, and is filled with a desiccant such as silica gel inside.

[0016] Accordingly, compressed air generated from the head and introduced into the dryer passes through a desiccant, has moisture removed, and is introduced into the air tank.

[0017] However, conventional dryers had the problem of high operating costs as the desiccant had to be replaced when the moisture absorbed in the desiccant became saturated.

[0018] In addition, conventional dryers cannot accurately determine the replacement time of the desiccant, and thus, if the replacement time of the desiccant is missed, there is a problem in that compressed air containing moisture flows into the air tank.

[0063] Fig. 1 is a perspective view showing a water centrifugal dryer according to an embodiment of the present invention mounted on an air compressor, and Fig. 2 is a front view showing a water centrifugal dryer according to an embodiment of the present invention.

[0064] Referring to FIGS. 1 and 2, a moisture centrifugal dryer (100) according to an embodiment of the present invention (hereinafter referred to as “moisture centrifugal dryer (100)”) includes a moisture removal unit (1) and a compressed air discharge unit (2).

[0065] The moisture removal unit (1) is connected to the head unit (HM) of the air compressor (AC).

[0066] Here, the connection of the moisture removal unit (1) to the head unit (HM) may include both the case where the moisture removal unit (1) is directly connected to the head unit (HM) and the case where the moisture removal unit (1) is indirectly connected to the head unit (HM) through another component connected to the head unit (HM).

[0067] For example, the moisture removal unit (1) may be directly connected to the head unit (HM) or indirectly connected to the head unit (HM) via a cooling fan connected to the head unit (HM).

[0068] The moisture removal unit (1) removes moisture from the compressed air introduced into the interior by using physical action.

[0069] More specifically, the moisture removal unit (1) is configured to remove moisture from the compressed air by centrifuging the moisture in the compressed air.

[0070] Figure 3 is a cross-sectional view taken along line III-III of Figure 2, and Figure 4 is an exploded view showing the moisture removal unit of Figure 2.

[0071] Referring to FIGS. 3 and 4, the moisture removal unit (1) may include a centrifugal separation tube (11) and a moisture induction discharge tube (12).

[0072] The centrifuge tube (11) can be connected to the head part (HM).

[0073] The centrifugal separator (11) can guide compressed air introduced into the interior from the head (HM) in a circumferential direction to separate moisture from the compressed air by centrifugal force, and guide and discharge the compressed air from which moisture has been removed upward.

[0074] FIG. 5 is a perspective view showing a centrifuge tube according to an embodiment of the present invention when viewed from the bottom, and FIG. 6 is a perspective view showing a centrifuge tube according to an embodiment of the present invention when viewed from the plane.

[0075] Referring to FIGS. 4 to 6, the centrifugal separation tube (11) may include a first tube body (111), a second tube body (112), a centrifugal separation guide groove (113), an air inlet hole (114), an air flow blocking block (115), a sealing ring (116), an air discharge hole (117), and a filter receiving groove (118).

[0076] The first pipe (111) can be accommodated inside the moisture induction discharge pipe (12).

[0077] The first pipe (111) can be formed to have an outer diameter smaller than the inner diameter of the moisture induction discharge pipe (12).

[0078] Accordingly, a gap can be formed between the outer surface of the first body (111) and the inner surface of the moisture induction discharge pipe (12), through which moisture condensed on the inner surface of the moisture induction discharge pipe (12) and compressed air from which moisture has been removed flow downward.

[0079] The second body (112) is placed outside the moisture induction discharge pipe (12), is supported on the upper end of the moisture induction discharge pipe (12), and can be coupled to the head portion (HM).

[0080] The centrifugal separation induction groove (113) can be formed by recessing into the outer surface of the first tube body (111).

[0081] The centrifugal separation induction groove (113) can induce compressed air introduced into the interior in a circumferential direction.

[0082] The air inlet hole (114) can penetrate the second tube (112) and the first tube (111) to connect the head part (HM) and the centrifugal separation induction groove (113).

[0083] The air inlet hole (114) can guide compressed air introduced from the head (HM) to the centrifugal separation induction groove (113).

[0084] For example, the air inlet hole (114) may include a first hole sunk to a predetermined depth in the radial direction of the second pipe body (112), and a second hole sunk to a predetermined depth in the central axis direction of the second pipe body (112) and communicating with the centrifugal separation induction groove (113). At this time, since the second hole is sunk from the upper surface of the second pipe body (112), a stopper member for shielding a portion of the second hole may be coupled to the upper portion of the second hole.

[0085] The air flow blocking block (115) can be coupled to the first tube (111) and placed in one section of the centrifugal separation induction groove (113).

[0086] The air flow blocking block (115) can block a section of the centrifugal separation induction groove (113) by contacting the inner surface of the moisture induction discharge pipe (12).

[0087] That is, the inner surface of the air flow blocking block (115) is formed in an arc shape corresponding to the centrifugal separation guide groove (113) and is in contact with the centrifugal separation guide groove (113), and the outer surface of the air flow blocking block (115) is formed in an arc shape corresponding to the inner surface of the moisture induction discharge pipe (12) and is in contact with the inner surface of the moisture induction discharge pipe (12).

[0088] Accordingly, the compressed air, from which moisture has been removed while moving in the circumferential direction along the inner surface of the centrifugal separation guide groove (113) and the moisture induction discharge pipe (12), reaches the section where the centrifugal separation guide groove (113) is closed by the air flow blocking block (115), and is guided downward by the air flow blocking block (115) and discharged through the gap formed between the outer surface of the first tube body (111) and the inner surface of the moisture induction discharge pipe (12).

[0089] For example, the air flow blocking block (115) can be connected to the first pipe (111) through a fastening means such as a bolt or the like.

[0090] The sealing ring (116) can be combined with the outer surface of the first body (111) and placed on the upper part of the centrifugal separation induction groove (113).

[0091] The sealing ring (116) can be tightly attached to the inner surface of the moisture induction discharge pipe (12) to seal the space between the first pipe body (111) and the moisture induction discharge pipe (12).

[0092] The sealing ring (116) can be formed of an elastic material such as rubber or silicone.

[0093] Air exhaust holes (117) can be arranged in multiple numbers at the center of the centrifuge tube (11).

[0094] The air discharge hole (117) can discharge compressed air that has entered the lower part of the first tube (111) after centrifugal separation of moisture by guiding it upward.

[0095] The filter receiving groove (118) can be sunken into the lower surface of the first body (111) to a preset depth and communicate with the air discharge hole (117).

[0096] A residual moisture removal filter (13) to be described later can be accommodated in the filter receiving home (118).

[0097] Referring to FIGS. 3 and 4, the moisture induction discharge pipe (12) can be connected to the centrifuge tube (11) and placed at the bottom of the centrifuge tube (11).

[0098] The moisture induction discharge pipe (12) can induce compressed air in the circumferential direction together with the centrifugal separation pipe (11) and simultaneously induce and discharge moisture separated from the compressed air by centrifugal force and condensed on the inner surface downward.

[0099] That is, the compressed air introduced into the centrifuge tube (11) is discharged into the space between the outer surface of the centrifuge tube (11) and the inner surface of the moisture-inducing discharge tube (12), and moves at high speed in the circumferential direction along the outer surface of the centrifuge tube (11) and the inner surface of the moisture-inducing discharge tube (12), and in this process, the moisture contained in the compressed air is centrifuged and condensed on the inner surface of the moisture-inducing discharge tube (12).

[0100] And, the compressed air from which moisture has been removed flows to the lower side of the centrifugal separation tube (11) through the gap formed between the outer surface of the centrifugal separation tube (11) and the inner surface of the moisture-inducing discharge tube (12), then flows into the inner central part of the centrifugal separation tube (11) and is discharged upward, and the moisture condensed on the inner surface of the moisture-inducing discharge tube (12) flows downward along the inner surface of the moisture-inducing discharge tube (12) and is discharged to the outside of the moisture-inducing discharge tube (12).

[0101] The moisture induction discharge pipe (12) may include a discharge pipe body (121) and a drain port (122).

[0102] The discharge pipe body (121) can be coupled to the centrifuge tube (11).

[0103] A first pipe body (111) is accommodated inside the discharge pipe body (121), and a second pipe body (112) can be supported on the upper part of the discharge pipe body (121).

[0104] The discharge pipe body (121) is formed with a structure in which the inner diameter size gradually decreases along the axial direction, so that moisture condensed on the inner surface can be guided downward.

[0105] For example, the discharge pipe body (121) can be connected to the centrifuge tube (11) through a fastening means such as a bolt or the like.

[0106] The drain port (122) is arranged at the lower end of the discharge pipe body (121) and can be communicated with the discharge pipe body (121).

[0107] The drain port (122) can discharge moisture moved to the lower side of the discharge pipe body (121) to the outside.

[0108] For example, a nipple pipe that guides moisture discharged from the drain port (122) to the outside, and a solenoid valve that is coupled to the nipple pipe and selectively opens and closes an internal flow path to discharge moisture flowing into the nipple pipe to the outside may be connected to the drain port (122). In addition, a silencer may be further connected to the end of the solenoid valve.

[0109] Referring to FIGS. 3 to 5, the moisture removal unit (1) may further include a residual moisture removal filter (13).

[0110] The residual moisture removal filter (13) can be combined with the centrifuge tube (11) and placed inside the centrifuge tube (11).

[0111] The residual moisture removal filter (13) can remove residual moisture from the compressed air by filtering the compressed air flowing upward and flowing into the interior of the centrifuge tube (11).

[0112] That is, the present moisture centrifugal dryer (100) can completely remove moisture in the compressed air by first removing moisture from the compressed air through the centrifugal separation tube (11) and then secondarily removing moisture from the compressed air through the residual moisture removal filter (13) arranged inside the centrifugal separation tube (11).

[0113] The residual moisture removal filter (13) may include a wire bundle (131) and a filter support cover (132).

[0114] The wire bundle (131) is accommodated in the filter accommodation groove (118) and can filter residual moisture from compressed air passing through the filter accommodation groove (118).

[0115] The wire bundle (131) can be formed of a metallic material.

[0116] More specifically, the wire bundle (131) may be in the form of a bundle of entangled stainless steel wires.

[0117] For example, the wire bundle (131) can filter micron-sized moisture from compressed air.

[0118] The filter support cover (132) can be coupled to the lower surface of the first body (111) to shield the entrance of the filter receiving groove (118).

[0119] An air flow hole (132A) through which compressed air flows in can be formed inside the filter support cover (132).

[0120] For example, the filter support cover (132) can be connected to the lower surface of the first body (111) through a fastening means such as a bolt or the like.

[0121] Referring to FIGS. 3 and 4, the moisture removal unit (1) may further include a moisture foreign matter removal filter (14).

[0122] The moisture foreign matter removal filter (14) is placed inside the moisture induction discharge pipe (12) and can remove foreign matter from moisture discharged to the outside of the moisture induction discharge pipe (12).

[0123] The moisture foreign matter removal filter (14) may include a filter support body (141) and a moisture foreign matter removal net (142).

[0124] The filter support body (141) is connected to the drain port (122) by being connected to the discharge pipe body (121), and can guide moisture flowing into the interior to the drain port (122).

[0125] For example, the filter support body (141) can be connected to the discharge pipe body (121) through a fastening means such as a bolt or the like.

[0126] The moisture foreign matter removal net (142) is supported by being joined to the outer surface of the filter support tube (141), and can filter foreign matter from moisture flowing into the filter support tube (141).

[0127] For example, the moisture foreign body removal net (142) may be formed of stainless steel and may be formed in a mesh structure.

[0128] Referring to FIGS. 1 to 3, the compressed air discharge unit (2) is coupled to the upper part of the moisture removal unit (1) and is connected to the air tank (AT) of the air compressor (AC).

[0129] The compressed air discharge unit (2) guides the compressed air discharged to the upper part of the moisture removal unit (1) and discharges it toward the air tank (AT).

[0130] Fig. 7 is an exploded view showing the compressed air discharge unit of Fig. 2.

[0131] Referring to FIG. 3 and FIG. 7, the compressed air discharge unit (2) may include an air discharge induction pipe (21), an upper shielding cover (22), and an auxiliary foreign matter removal filter (23).

[0132] The air exhaust induction pipe (21) can be connected to the upper part of the moisture removal unit (1).

[0133] The air exhaust induction pipe (21) can guide compressed air with moisture removed, discharged to the upper part of the moisture removal unit (1), upward.

[0134] For example, the air exhaust induction pipe (21) can be connected to the air exhaust induction pipe (21) and the moisture induction discharge pipe (12) by being connected to a fastening means such as a bolt that penetrates the moisture induction discharge pipe (12) and the centrifuge tube (11).

[0135] The upper shielding cover (22) is connected to the upper part of the air exhaust induction pipe (21) to shield the upper part of the air exhaust induction pipe (21) and can be connected to the air tank (AT).

[0136] The upper shielding cover (22) can discharge compressed air flowing to the upper side of the air discharge induction pipe (21) toward the air tank (AT).

[0137] A hole can be formed in the center of the upper shielding cover (22) to connect the internal space of the air tank (AT) and the air exhaust induction pipe (21).

[0138] For example, the upper shielding cover (22) can be connected to the air exhaust induction pipe (21) through a fastening means such as a bolt that penetrates the upper shielding cover (22) and is connected to the upper end of the air exhaust induction pipe (21).

[0139] The auxiliary foreign matter removal filter (23) can be coupled to the lower surface of the upper shielding cover (22) and accommodated inside the air exhaust induction pipe (21).

[0140] The auxiliary foreign matter removal filter (23) can remove foreign matter from the compressed air discharged from the air discharge induction pipe (21) to the upper shielding cover (22).

[0141] The auxiliary foreign matter removal filter (23) may include an auxiliary support body (231) and an auxiliary foreign matter removal net (232).

[0142] The auxiliary support body (231) is connected to the upper shielding cover (22) and communicates with the upper shielding cover (22), and can guide compressed air introduced into the interior to the upper shielding cover (22).

[0143] For example, the auxiliary support body (231) can be connected to the upper shield cover (22) through a fastening means such as a bolt or the like.

[0144] The auxiliary foreign body removal net (232) can be supported by being joined to the outer surface of the auxiliary support body (231).

[0145] The auxiliary foreign matter removal net (232) can filter foreign matter from the compressed air flowing into the auxiliary support pipe (231).

[0146] For example, the auxiliary foreign body removal net (232) may be formed of stainless steel and may be formed in a mesh structure.

[0147] The auxiliary foreign matter removal filter (23) can be configured to remove residual moisture from compressed air from which foreign matter has been removed.

[0148] The auxiliary foreign matter removal filter (23) may further include an auxiliary wire bundle (233).

[0149] The auxiliary wire bundle (233) is accommodated inside the auxiliary support tube (231) and can filter residual moisture from compressed air passing through the auxiliary support tube (231).

[0150] The auxiliary wire bundle (233) can be formed of a metallic material.

[0151] The auxiliary wire bundle (233) may be separated from the interior of the auxiliary support body (231) as needed.

[0152] More specifically, the auxiliary wire bundle (233) may be in the form of a bundle of entangled stainless steel wires.

[0153] For example, the auxiliary wire bundle (233) can filter micron-sized moisture from compressed air.

[0154] Additionally, although not shown in the drawing, the compressed air discharge unit (2) may further include a high-performance purification filter (not shown).

[0155] The high-performance purification filter can be installed on the outer surface of the auxiliary foreign matter removal filter (23) or can be installed as a replacement at the location where the auxiliary foreign matter removal filter (23) is installed.

[0156] The high-performance purification filter can remove micron-sized fine particles from the compressed air by filtering the compressed air discharged from the air discharge induction pipe (21) to the upper shielding cover (22).

[0157] For example, a high-performance purification filter may be a HEPA (High Efficiency Particulate Air) filter that removes 99.99% of particles larger than 0.3㎛, or an ULPA (Ultra Low Penetration Air) filter that removes 99.999% or more of particles larger than 0.1 to 0.3㎛ that cannot be filtered by a HEPA filter. However, a high-performance purification filter is not necessarily limited to this, and may be equipped with both a HEPA filter and an ULPA filter.

[0158] Referring to FIG. 3 and FIG. 7, the compressed air discharge unit (2) may further include a bracket (24) and a shielding ring (25).

[0159] The bracket (24) may include a first bracket (241) that is arranged between the centrifuge tube (11) and the air exhaust guide tube (21) and coupled to the air compressor (AC), and a second bracket (242) that is arranged between the air exhaust guide tube (21) and the upper shielding cover (22) and coupled to the air compressor (AC).

[0160] The shielding ring (25) is a first shielding ring (251) made of an elastic material that is coupled to the upper surface of the centrifuge tube (11) and is in close contact with the lower surface of the first bracket (241) to seal the space between the centrifuge tube (11) and the first bracket (241), a second shielding ring (252) made of an elastic material that is coupled to the lower surface of the air exhaust guide tube (21) and is in close contact with the upper surface of the first bracket (241) to seal the space between the air exhaust guide tube (21) and the first bracket (241), a third shielding ring (253) made of an elastic material that is coupled to the upper surface of the air exhaust guide tube (21) and is in close contact with the lower surface of the second bracket (242) to seal the space between the air exhaust guide tube (21) and the second bracket (242), and a third shielding ring (253) made of an elastic material that is coupled to the lower surface of the upper shielding cover (22) and is in close contact with the upper surface of the second bracket (242) to seal the space between the upper shielding cover (22) and the second It may include a fourth shielding ring (254) made of elastic material that seals the space between the brackets (242).

[0161] Meanwhile, although not shown in the drawing, the present water centrifugal dryer (100) may further include a water separation membrane.

[0162] The moisture separation membrane can be placed inside the residual moisture removal filter (13).

[0163] In more detail, the moisture separation membrane is accommodated in the filter accommodation groove (118) and can be arranged in a multi-layer structure on top of the wire bundle (131).

[0164] Accordingly, the moisture separation membrane can completely separate the remaining moisture in the compressed air by multi-filtering the compressed air flowing through the wire bundle (131) to the upper part of the centrifuge tube (11) once more.

[0165] For example, the moisture separation membrane may be a microporous membrane formed of at least one material selected from the group consisting of polyimide, polyester, and cellulose triacetate.

[0166] In addition, although not shown in the drawing, the present moisture centrifugal dryer (100) may further include a humidity sensor installed inside the air exhaust induction pipe (21) to detect the internal humidity of the air exhaust induction pipe (21), and an opening / closing valve installed inside the air exhaust induction pipe (21) to open / close the flow path of the air exhaust induction pipe (21) according to the humidity information detected by the humidity sensor.

[0167] The opening / closing valve may include an opening / closing plate that is rotatably coupled to an air exhaust induction pipe (21) to selectively open / close the internal flow path of the air exhaust induction pipe (21), and an opening / closing plate driving actuator that is arranged on the outside of the air exhaust induction pipe (21) and is configured to rotate the opening / closing plate.

[0168] The opening / closing plate drive actuator is linked to a humidity sensor and can open / close the flow path of the air exhaust induction pipe (21) by operating the opening / closing plate based on humidity information detected by the humidity sensor.

[0169] For example, if the humidity information detected by the humidity sensor falls within a preset threshold range, the opening / closing plate drive actuator can place the opening / closing plate in a first state to open the passage of the air exhaust induction pipe (21). In addition, if the humidity information detected by the humidity sensor does not fall within a preset threshold range, the opening / closing plate drive actuator can place the opening / closing plate in a second state to close the passage of the air exhaust induction pipe (21).

[0170] In this way, according to an embodiment of the present invention, moisture is removed from compressed air by centrifugation without using a desiccant, so maintenance costs can be reduced and permanent use can be possible without replacing the desiccant.

[0171] In addition, after removing moisture through centrifugation in the centrifuge tube (11), the remaining moisture in the compressed air is additionally removed through the residual moisture removal filter (13) contained inside the centrifuge tube (11), so that moisture can be completely removed from the compressed air.

[0172] In addition, an auxiliary foreign matter removal filter (23) that removes foreign matter and residual moisture from compressed air is arranged at the bottom of the upper shielding cover (22), thereby preventing foreign matter from entering the air tank (AT) and maximizing the moisture removal performance of the dryer.
