Description

Dry cleaning machine capable of controlling dry ice particles

Technical Field

The present invention relates to a dry cleaner capable of controlling dry ice particles, and more particularly, to a dry cleaner capable of controlling dry ice particles, which can selectively and freely adjust the particle size of dry ice, and can clean various machines, equipment, and the like by spraying the dry ice having the adjusted particle size at a high speed using compressed air.

Background

Recently, a technique for cleaning the surface of an object to be cleaned without any defect has been developed for dry cleaning using sublimable solid particles typified by dry ice.

Dry ice, which is one of the sublimable solid particles used in the dry cleaning process, is formed into a pellet shape, and the pellet-shaped dry ice is mixed with high-pressure compressed air and sprayed onto the surface of the cleaning object, thereby cleaning the cleaning object.

In a conventional dry ice cleaning device, hard dry ice particles harmless to industrial equipment and the environment are sprayed at a high speed to remove foreign matters.

Since the amount and speed of the dry ice sprayed can be adjusted to some extent, foreign substances attached to the surfaces of machines and products made of various materials, such as ceramics, synthetic resins, rare metals, glass fibers, rubbers, plastics, steel materials, etc., can be removed. The dry ice particles can be immediately sublimated into harmless gas by colliding with the surface, and only foreign matters are removed without causing any damage to the cleaning surface, and pollutants, moisture and the like are not left for 2 times.

If dry ice cleaning is adopted, investment expenses newly invested in a punching die, a forming frame and the like can be saved due to the fact that the service life of equipment is prolonged. The time required for the cleaning work and the time and cost required for collecting and treating 2 contaminants generated in the conventional cleaning can be reduced, and thus the total operation expenses can be reduced. At present, production facilities or products can be perfectly cleaned at industrial sites even without using Volatile Organic Compounds (VOC), ozone Depleting Substances (ODS), wastewater-inducing solvents, and the like, which are prohibited from being used by environmental protection related regulations.

Dry ice cleaning is widely used in all industrial fields such as food processing, pastry making, rubber, plastics, pharmaceuticals, automobile manufacturing, aircraft maintenance, space aviation, electrical and electronic, semiconductor industry, petrochemical, iron making, printing, casting industry and the like. Dry ice cleaning is currently used in all industrial fields that depend on chemical products such as sandblasting (sandblasting), steam cleaning, solvents (solvent), etc., or on conventional cleaning operations such as manual scraping, etc., so that not only can the cost be saved, the productivity be improved, the quality be improved, the environment be protected, but also a safe and clean working environment can be ensured.

As described above, the conventional dry ice cleaning apparatus, which is carefully examined, includes: a hopper formed to have a wide upper portion and a narrow lower portion so that dry ice can be filled and placed, and having an entrance and an exit at a lower end portion thereof; a rotor provided to be rotatable at a lower portion of a drawing port of the hopper, and having supply grooves formed at regular intervals on an outer periphery thereof, the supply grooves being capable of receiving a supply of dry ice discharged from the drawing port; and a supply pipe connected to the supply groove of the rotor, for discharging the dry ice falling from the supply groove by compressed air of the compressor.

In such a conventional dry ice cleaning device, if the rotor is rotated by the motor, the rotor rotates and, at the same time, dry ice is discharged from the hopper and filled into the supply groove formed on the outer periphery thereof, and then falls down to the supply pipe. At this time, if the compressor injects compressed air, the dry ice pellets are injected at a high speed and collide with the surface of the object to be cleaned, thereby removing the foreign matter layer.

However, the conventional dry ice cleaning device has a problem that the cleaning power cannot be adjusted because the particle size of the dry ice cannot be adjusted.

Further, since the adjustment of the cleaning force is not easy, there is a problem that damage due to impact is generated when cleaning precision electronic parts and the like.

The dry ice particle regulating device 1 according to the present invention may include a body part 10, a grinding part 20, and a regulating part 30.

The main body 10 is formed in a substantially polygonal box shape or a circular box shape, and has an inlet formed on the upper surface thereof, into which pellet-shaped dry ice D is put.

Further, an accommodating space 10a for accommodating dry ice D is formed inside the main body 10, an exposure hole 12a is formed in a central portion of the bottom surface 12 of the accommodating space 10a, and the exposure hole 12a exposes a polishing portion 20 described later while allowing the dry ice D to pass therethrough.

The bottom surface 12 is formed in a shape whose width gradually decreases from the upper portion toward the lower portion where the exposure hole 12a is formed. Therefore, the dry ice D falling on the bottom surface 12 descends along the inclined path of the bottom surface 12 and is supplied to the grinding section 20.

Further, a discharge port is formed at the lower side of the main body 10, and the discharge port can discharge the dry ice D, the particle size of which is adjusted by the grinding part 20, to the outside.

A lid 11 for opening and closing the input button is hinged to the upper side of the main body 10.

Further, on the outer surface of the main body 10 are provided: a RPM (Revolutions Per Minute) adjusting part 134 of dial control type for adjusting the RPM of a driving part for rotating the grinding machine 21 to be described later so as to adjust the spraying amount of the dry ice D; and a dial-up control type pressure adjusting unit 14 for adjusting the pressure of the air compressor 110 to adjust the speed of spraying the dry ice D.

The grinding part 20 adjusts the particle size of the dry ice D, and includes a grinder 21 and a support part 22 disposed opposite to each other in the inner space of the body part 10.

The grinder 21 is rotated in situ by the power of a motor (not shown) to continuously grind the dry ice D along the edge surface in the form of serrated blades (not shown) at regular intervals.

The grinder 21 is formed with a hollow portion, and a rotating shaft 211 is provided to penetrate the hollow portion.

Both sides of the rotating shaft 211 protrude to the outside of the grinder 21 and are fixed between a pair of rotating guide plates 23.

The support portion 22 is disposed on a fixing member 33, which will be described later, so as to be spaced from the grinder 21 with an adjustable distance.

The support portion 22 is spaced apart from the grinder 21 at a prescribed interval so that the dry ice D can pass through.

In other words, the dry ice D falling through the exposure hole 12a is ground by the grinder 21 in a state of being supported by the support portion 22, so that the particle diameter is changed.

At this time, the support portion 22 is formed as a polygonal body so as to generate surface friction of the dry ice D. A through hole 22a is formed eccentrically in the support portion 22, and a rotating shaft 32 described later is inserted through the through hole 22 a.

The adjusting portion 30 is configured to adjust the interval between the grinder 21 and the supporting portion 22 so that the particle size of the dry ice D can be selectively adjusted.

In other words, the adjusting portion 30 moves the support portion 22 forward or backward with respect to the grinding machine 21 to adjust the interval and determine the particle diameter of the dry ice D matching the interval.

For this, the adjusting part 30 may include a rotation shaft 32, a rotation control member 31, a fixing member 33, and a shielding member 34.

The rotating shaft 32 is eccentrically disposed on the support portion 22 by penetrating the through hole provided in the support portion 22 as described above.

The rotating shaft 32 rotates in accordance with the operation of a rotation control member 31 described later, thereby adjusting the distance between the support portion 22 and the grinder 21.

The rotation control part 31 is a structure for providing power for moving the grinder 21, and may include a rotation handle 311 and a spacing adjustment lever 312.

The rotation knob 311 is exposed to the outside of the body portion 10 so as to be controllable by an operator.

The rotation knob 311 may be formed in a circular shape, and a plurality of valleys and peaks preventing the sliding of the finger are continuously formed to cross along the edge thereof.

The interval adjustment rod 312 may be formed in a circular rod shape having a certain length and diameter, buried in the inner space of the case 35.

The housing 35 is disposed in a space provided below the bottom surface 12 of the main body 10, and is spaced apart from the grinder 21 and the support portion 22 by a predetermined interval.

At this time, a portion of the rotating shaft 32 is introduced into the inner space of the housing 35 so as to be opposite to the interval adjusting lever 312.

And, gears (not shown) engaged with each other are installed at the outer circumference of the interval adjustment rod 312 and the outer circumference of the rotation shaft 32, respectively.

Therefore, the interval adjustment lever 312 can be rotated in a forward direction or a reverse direction by rotating the handle 311 outside the body 10, and the rotating shaft 32 and the support portion 22 are rotated in the rotating direction of the interval adjustment lever 312, so that the support portion 22 approaches or separates from the grinder 21.

Therefore, the distance between the grinder 21 and the support portion 22 is adjusted by rotating the handle 311 in the forward direction or the reverse direction to rotate the distance adjustment lever 312, and then the dry ice D is poured and molded into a desired particle size.

The fixing member 33 is disposed in an internal space separately provided below the bottom surface 12 of the main body 10 and faces the grinder 21.

An inclined surface 331 for dropping the dry ice D passing through the exposure hole 12a is formed on the upper surface of the fixing member 33.

An access groove 33b through which the support portion 22 can be accessed is formed at a substantially central portion in the height direction of the fixing member 33, and a collecting groove 33c for collecting dry ice D whose particle diameter is changed by the grinder 21 and the support portion 22 is formed in the bottom surface in the longitudinal direction.

At this time, the support portion 22 is movable forward or backward with respect to the grinder 21 in a state of being accommodated in the exit groove 33b, and moves in a direction of being drawn out from the exit groove 33b when moving forward, and moves in a direction of being drawn into the exit groove 33b when moving backward.

Also, a connection hole (not shown) connected to the catch tank 33c is formed in the body portion 10, and a spray portion 120 of the dry cleaner 100, which can control dry ice particles, which will be described later, is connected to the connection hole.

A guide surface 33a formed in an inclined direction and guiding the dry ice D in the direction of the catch tank 33c is formed between the entrance/exit tank 33b and the catch tank 33c.

The guard member 34 is disposed opposite to the fixing member 33 to protect the grinder 21.

A receiving groove (not shown) for receiving a part of the grinder 21 may be formed at a surface of the shielding member 34 opposite to the fixing member 33.

Further, a display unit 40 is provided on the outer surface of the main body 10, and the display unit 40 is operated in conjunction with the rotation of the interval adjustment lever 312, and indicates the particle diameter of the dry ice D to be ground by a numeral.

The display unit 40 includes a 3-digit or 4-digit number (including a decimal point).

The numerals of the display unit 40 indicate the particle size of the dry ice D ground in accordance with the different intervals between the grinder 21 and the support 22 as the interval adjustment lever 312 is rotated in the forward or reverse direction.

The configuration and operation principle of the display unit 40 are common techniques, and therefore, detailed description thereof is omitted.

The dry cleaner 100 capable of controlling dry ice particles according to the present invention will be explained.

Fig. 7 is a perspective view showing a dry cleaner capable of controlling dry ice particles according to the present invention, fig. 8 is a perspective view showing first and second detaching portions of the dry cleaner capable of controlling dry ice particles according to the present invention, and fig. 9 is a perspective view showing operations of the first and second detaching portions of the dry cleaner capable of controlling dry ice particles according to the present invention.

The dry cleaner 100 capable of controlling dry ice particles according to the present invention may include: the aforementioned dry ice particle adjustment device 1, the blasting portion 120, and the control module 50 are described below, wherein the blasting portion 120 includes an air compressor that supplies compressed air to the catch tank 33c of the fixing member 33, and blows dry ice onto the object to be cleaned.

The injection unit 120 includes, in addition to the air compressor 110: a supply pipe 121 that penetrates the main body 10 and the moving plate 34, is fixed to the other end portion of the fixed member 33 at the collecting tank 33c, and receives and transfers the dry ice D in the collecting tank 33c when the air compressor 110 is operated; a jet body part 122 connected to the supply pipe 121 and formed therein with a passing hole through which the dry ice D supplied from the supply pipe 121 passes; a spray nozzle 123 provided with a connection pipe 1231 connected to the spray body part 122 so that dry ice D can be sprayed; first and second disassembly parts 124 and 125, which allow the supply tube 121 and the connection tube 1231 to be coupled to or separated from the injection main body part 122, respectively.

First, the air compressor 110 supplies compressed air which becomes the initial power when the dry ice D is sprayed, and includes an air pipe 111 which penetrates the main body 10 and the moving plate 34 and is fixed to one side end portion of the catch tank 33c of the fixed member 33, and supplies the compressed air to the catch tank 33c, thereby spraying the ground dry ice D to the object to be cleaned through the spray nozzle 123.

Here, the injection body part 122 is provided with an on/off switch S for controlling the operation of the air compressor 110.

In other words, if the on/off switch is pressed once, the air compressor 110 continues to operate, so that the dry ice D in the collecting tank 33c can be continuously sprayed, and if the on/off switch is pressed again, the operation of the air compressor 110 is stopped, which can reduce the fatigue of the operator and provide convenience in use.

The first and second detaching portions 124 and 125 are used to couple or separate the supply pipe 121 and the connection pipe 1231 to or from the injection part body 122 in one touch (one touch) type, and may include: main bodies 1341 and 1251 fixed to the inlet side and the outlet side of the passage hole of the injection main body 122, respectively, formed in a cylindrical shape, the inside of which is connected to the passage hole of the injection main body 122, and having a plurality of pressure balls 1242 and 1252 formed at the inner periphery thereof so as to be spaced apart from each other; drawing portions 1243 and 1253 which are fixed to end portions of the supply pipe 121 and the connection pipe 1231, respectively, are formed in a cylindrical shape, are connected to the through hole of the injection main body portion 122 inside thereof, are attached to the inside of the body portions 1341 and 1251, and are pressurized against the pressurizing balls 1242 and 1252 from the outside thereof; the

operation portions

1244 and 1254 are attached to the outer surfaces of the main bodies 1341 and 1251, respectively, and can move forward and backward with respect to the jet body portion 122.

The pressure balls 1242 and 1252 are inserted into the body portions 1341 and 1251, are movable toward the inner space or outside of the body portions 1341 and 1251, are elastically supported by a spring (not shown), and are controlled to be operated by the forward and backward movement of the

operation portions

1244 and 1254.

Further, the

operation portions

1244 and 1254 are elastically supported by a spring (not shown), and thus automatically advance and return to the original positions when artificially retreated.

In other words, after the

operating portions

1244 and 1254 are grasped and the pressure balls 1242 and 1252 are retracted and disengaged, the introduction portions 1243 and 1253 are inserted into the main body portions 1341 and 1251, and then if the operating

portions

1244 and 1254 are loosened to return to their original positions, the pressure balls 1242 and 1252 press the outer surfaces of the introduction portions 1243 and 1253 to be fixed, and the supply pipe 121 and the connection pipe 1231 can be easily coupled to and separated from the injection main body portion 122 in one touch by the first and second detachable portions 124 and 125. Accordingly, when abnormality or deterioration occurs in the supply pipe 121 and the connection pipe 1231, replacement with a new product can be easily and quickly performed.

In this case, the first and second additional

detachable portions

15 and 16 having the same structure as the first and second detachable portions 124 and 125 may be provided outside the main body portion 10.

At this time, the lower side of the supply pipe 121 is fixed by the first additional removing part 15, and one side of the air pipe 111 is fixed by the second additional removing part 16.

Also, fixing pipes (not shown) fixed to the collecting grooves 33c instead of the supply pipe 121 and the air pipe 111 may be provided at the first and second additional dissembling

portions

15 and 16.

Accordingly, the compressed air of the air compressor 110 is supplied to the collecting tank 33c through the air pipe 111, the second additional disassembly part 16, and the fixed pipe, whereby the dry ice D is supplied to the spray nozzle 123 through the fixed pipe of the first additional disassembly part 15, the supply pipe 121, the spray body part 122, and the connection pipe 1231.

The control module 50 operates the air compressor 110 for a set period of time as the start signal is input from the injection part as the on/off switch S is pressed by the operator, thereby discharging the foreign substances and moisture existing in the collection tank 33c through the injection nozzle 123.

Then, the control module 50 operates the motor for rotating the grinder 21, and if the dry ice D is immediately put into the storage space 10a of the main body 10, only the clean compressed air and the dry ice are sprayed to the object to be washed.

Further, as the operator presses the on/off switch S again, the control module 50 stops the operation of the motor when the injection part 30 inputs the termination signal, so that the air compressor 110 is operated for a set time period, thereby discharging the foreign substances and moisture existing in the collection tank 33c through the injection nozzle 123.

Next, the forming part 130 applied to the dry cleaner 100 capable of controlling dry ice particles according to the present invention will be described with reference to fig. 10 to 12.

Fig. 10 is a sectional view showing an upper mold, a lower mold, and a lifting driving part applied to a dry cleaner capable of controlling dry ice particles according to the present invention, and fig. 11 and 12 are views showing operation states of a turning plate, a turning guide shaft, and a turning driving part applied to the dry cleaner capable of controlling dry ice particles according to the present invention.

The forming part 130 may include an upper mold 131, a lower mold 132, a lifting driving part 133, a rotation plate 134, a rotation guide shaft 135, and a rotation driving part 136, so that a plurality of mountain parts D1 and valley parts D2 crossing each other are formed on an edge surface of the dry ice D.

In this case, in the present embodiment, the dry ice D formed by the forming portion 130 is not ground by the grinder 21 and the support portion 22, but is directly collected by the collecting groove 33c and then sprayed to the object to be cleaned by the spraying portion 120.

In other words, the present embodiment is configured to selectively use either the dry ice D whose particle diameter is adjusted by the grinder 21 and the support portion 22 or the dry ice D formed by the forming portion 130.

Specifically, the first storage groove 131a is formed in a semicircular shape having an open top surface along the longitudinal direction of the upper mold 131, and is formed at a constant interval to store the lower portion of the dry ice D, and the first storage groove 131a is formed with a plurality of first pressing projections 1311 formed at a constant interval to press the dry ice D so that the mountain portions D1 and the valley portions D2 are formed.

The lower mold 132 is disposed above the upper mold 131, the second receiving groove 132a is formed in a semicircular shape having an open bottom along the longitudinal direction thereof to face the first receiving groove 131a, receives the upper portion of the dry ice D received in the first receiving groove 131a, and is formed at a constant interval, and the second receiving groove 132a is formed with a plurality of second pressing projections 1321 formed at a constant interval by pressing the dry ice D such that the mountain portions D1 and the valley portions D2 are formed.

At this time, the first and second

pressing protrusions

1311 and 1321 may be formed in a semicircular shape or a quadrangular shape so that the mountain portion D1 is formed in a curved or quadrangular shape, an example of which is formed in a semicircular shape is shown in the drawings.

The elevation driving part 133 may be provided as a hydraulic cylinder such that the lower mold 132 is lowered so that the first and second pressurizing

protrusions

1311 and 1321 pressurize the dry ice D.

At this time, the elevation driving part 133 is lowered so that the upper mold 131 is in close contact with or approaches the lower mold 132.

In other words, in the dry ice D, the portions pressurized by the first and second pressurizing

protrusions

1311, 1321 form notched ridges D1, and the portions not pressurized by the first and second pressurizing

protrusions

1311, 1321 form ridges D1.

After the formation of the dry ice D, the upper mold 131 is raised by the elevation driving unit 133 to take out the dry ice D stored in the first storage groove 131a, and then moved to the turning plate 134.

The turning plate 134 is opposed to the main body 10 and is located at a position higher than the inlet, and the formed dry ice D is placed thereon.

The vertical rotation guide shaft 135 is axially fixed to a bottom surface of the rotation plate 134, and the rotation plate 134 is rotatable in a vertical direction.

The rotation driving part 136 may be formed as a hydraulic cylinder, and a piston is fixed to the other side of the bottom surface of the rotation plate 134 so that the rotation plate 134 can be rotated in the up and down directions.

In other words, if hydraulic pressure is injected into the rotation driving part 136, the piston is raised, and thereby the rotation plate 134 is rotated in the up and down direction, so that the dry ice D placed thereon is automatically thrown into the inner space of the body part 10.

At this time, the grinder 21 and the support portion 22 are disposed at a distance greater than the particle size of the dry ice D formed by the forming portion 130, and the formed dry ice D directly falls to the collection tank 33c without contacting the grinder 21 and the support portion 22, and then is sprayed to the object to be cleaned in the above-described manner, thereby removing the foreign substance layer.

In particular, when a plurality of grooves smaller than the dry ice D are formed by applying impact to the object to be cleaned, the dry ice D may not contact the foreign substance layer stored in the groove, and thus the foreign substance layer may not be removed, but the dry ice cleaning machine 1 according to the present invention intensively sprays the formed dry ice D to the groove portion of the object to be cleaned, thereby removing the foreign substance layer.

In other words, if the dry ice D formed is sprayed to the groove of the object to be cleaned, the mountain portion D1 of the dry ice D is drawn into the groove of the object to be cleaned and comes into contact with the foreign substance layer stored on the surface of the groove.

Therefore, when the groove is formed in the object to be cleaned, first, unformed dry ice D is put into the main body 10, and the foreign matter layer hidden in the portion where the groove is not formed is removed, and then, the formed dry ice D is put into the main body 10 and is intensively sprayed to the groove portion of the object to be cleaned, thereby perfectly cleaning the entire object to be cleaned.

Of course, when the object to be cleaned has no groove, the object to be cleaned may be cleaned only by using the dry ice D formed by the grinder 21 and the grinding portion 20.

It is to be understood that a person having ordinary skill in the art to which the present invention pertains may adopt other specific forms without changing the technical spirit or essential features of the present invention. Therefore, the above-described embodiments are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the scope of the claims to be described later than the detailed description above, and all modifications and variations derived from the meaning and scope of the claims and equivalent concepts thereof should be construed as being included in the scope of the present invention.
