Description

  The present invention relates to a dry cleaning device used for dry cleaning in which a cleaning medium flying by a swirling airflow contacts or collides with an object to be cleaned, and a dry cleaning apparatus including the same, and more specifically, a container or a long tubular tube The present invention relates to a dry cleaning device and a dry cleaning apparatus suitable for internal body cleaning.

2. Description of the Related Art In recent years, various dry cleaning methods have been developed in which a flake-like cleaning medium is carried on a high-speed circulating air stream and brought into contact with an object to be cleaned to remove dirt.
For example, in Patent Document 1, an object to be cleaned is held in a cleaning tank, and a cleaning medium flying by a circulating airflow in the cleaning tank is accelerated by a high-speed compressed air flow from a different angle to collide with the cleaning medium. Technology is disclosed.
In Patent Documents 2 and 3, when the inside of a casing that can be moved in a handheld state is sucked and the opening provided in a part of the casing is closed against a cleaning medium, it flows from the outside of the casing. A technique is disclosed in which a swirling airflow is generated in which a cleaning medium is caused to fly inside a housing by an airflow, and the cleaning medium is collided with an object to be cleaned at an opening.
By moving the housing and shifting the position of the opening, it is possible to clean any part, and a large area can be cleaned.
Moreover, since it is a handy type, it has an advantage that even a large-sized object to be cleaned can be easily cleaned as long as there is a portion that can be blocked by applying the opening.

In dry cleaning using flaky cleaning media, it is known that when the cleaning media flies at high speed and hits the cleaning surface, the edge of the cleaning media bites in and scrapes off the dirt, so that a high cleaning effect is obtained. ing.
Washing in a dry manner without using water or solvent can reduce the washing cost and environmental burden, and can also contribute to the improvement of the working environment.
In addition, dirt adhered to a film which is difficult to remove with water or a solvent can be removed by the biting and scraping action by the edge of the thin piece.

By the way, as a need for dry cleaning, there is an object that is difficult to clean using water, such as the inside of an air conditioning duct.
In addition, fixed dirt that cannot be removed by washing with water may be generated inside an elongated container such as a water bottle or pot.
The back of the elongate container is difficult to clean because hands and cleaning tools are difficult to act on.

As described above, in the prior art, hard dirt and adhesive particles can be removed without damaging the base material by colliding the flaky cleaning medium with a high-speed airflow.
However, in the conventional cleaning method, it was difficult to clean the inside of the container or the tube.
For example, in the method described in Patent Document 1 in which an object to be cleaned is placed in a cleaning tank, it is difficult for airflow to hit the inside of the container.
When the object to be cleaned has a container shape, there is a blind spot portion even if a high-speed airflow is applied from the outside, and the cleaning medium does not fly sufficiently in that portion, and the cleaning ability is low.
In the handy-type cleaning devices described in Patent Documents 2 and 3, when the casing is large, the opening cannot be applied to the inside of the container, and cleaning cannot be performed.

In addition, even the inner wall of a container or tube having a sufficiently large housing insertion space, the entire surface cannot be cleaned unless an opening having an area smaller than the size of the housing is translated, so that the cleaning efficiency is extremely poor. There was a problem.
In the techniques described in Patent Documents 2 and 3, an air intake for generating a swirling air flow called an inlet protrudes outward from the outer peripheral surface of the housing in order to obtain a rectifying action, and easily interferes with the container.
In addition to this, when the inlet is located in the container, there is a problem that the intake efficiency is poor and the swirling airflow that is inevitably generated becomes weak.
Also, in order to maintain a negative pressure in the housing and obtain a high-speed swirling airflow, it is necessary for the opening to be in close contact with the cleaning surface of the object to be cleaned. The contact state of the opening cannot be obtained, and a high-speed swirling air current cannot be obtained.

Although it is not dry cleaning, a nozzle head that jets high-pressure water is set inside the pipe, the nozzle head is swung at high speed by the reaction of the jet, and the jet water collides with the entire circumference of the pipe to remove dirt. Is also known.
In this system, even if air is blown instead of water, the cleaning ability is low, and the application range for the object to be cleaned is extremely narrow.

  This invention is made | formed in view of such a present condition, and the main objective is to provide the dry-type washing | cleaning device which can wash | clean the inside of a container and a tubular body favorably.

In order to achieve the above object, the present invention does not apply the cleaning medium to the object to be cleaned only by the opening of the housing as in the techniques described in Patent Documents 2 and 3, but the inner surface of the object to be cleaned and the housing. It was decided to generate a swirling airflow that caused the cleaning medium to fly between the body and the body.
That is, the “outside casing turning method” is used in contrast to the conventional “inside casing turning method”.
In this way, the cleaning medium can be applied regardless of the shape of the inner surface of the object to be cleaned, and there is no need to move the housing.
Moreover, the structure which an inlet protrudes outside the housing | casing by the difference in a turning system can also be avoided.

  Specifically, the present invention includes a hollow housing that is used by being inserted into the object to be cleaned so as to form a surrounding space between the inner peripheral surface of the object to be cleaned, and the housing An air inlet for connecting the inside of the housing to suction means so as to be capable of being sucked, an injection port provided in the housing and partitioned from an internal space of the housing, and opening to an outer peripheral surface of the housing; An air intake port that communicates with the mouth, and the housing has a shape or configuration that creates a negative pressure in the surrounding space when the inside of the housing is sucked, and the inside of the housing is sucked When this is done, the dry cleaning device is characterized in that air flowing in from the air intake port is injected from the injection port to generate a swirling air current that causes the cleaning medium to fly in the circulation space.

  According to the present invention, it is possible to clean the inside of a container or a tubular body without using water, a solvent, or the like, and the scope of application of an object to be cleaned in a dry cleaning system having an advantage of reducing cleaning cost and environmental load. Can contribute to expansion.

FIG. 4 is a diagram showing a state in which a new cleaning medium is replenished.

Embodiments of the present invention will be described below with reference to the drawings.
First, a first embodiment will be described with reference to FIGS.
FIG. 1 is a perspective view of a dry cleaning device according to the present embodiment. The dry cleaning device 2 has a hollow (cylindrical) housing 4 and a cylindrical air inlet 6 formed on the upper surface of the housing 4 with the center position shifted.
The air inlet 6 is a member for connecting the inside of the housing 4 to a suction means (described later) so as to be sucked.

Further, the dry cleaning device 2 has a length extending in the axial direction of the housing 4, and has a vertically-slit-shaped ejection port 8 that opens on the outer peripheral surface of the housing 4, and an air intake port 10 that communicates with the ejection port 8. And have.
Further, the dry cleaning device 2 has a nozzle connection port 12 and a cleaning medium discharge port 14 formed on the bottom surface (insertion side end) of the housing 4.

A large number of holes 4 a are formed in the outer peripheral surface (outer surface) of the housing 4, and the inside of the housing 4 can be ventilated to the outside. That is, the housing 4 is porous.
The hole 4a does not pass through the cleaning medium, and is set to a size that allows the cleaning medium that has become smaller due to wear or the like or the removed foreign matter to pass therethrough.
The “porosity” of the housing 4 can be realized not only by a structure having a large number of holes but also by a structure having a large number of slits.
In short, any structure may be used as long as it does not allow the cleaning medium to pass but allows the removed foreign matter or the like to pass through and allows negative pressure in the casing 4 and the surrounding space (described later).
A plurality of nozzle holes 4 b are formed in the vicinity of the injection port 8 on the outer peripheral surface of the housing 4 at intervals in the axial direction.

As shown in FIG. 2 (b), which is a cross-sectional view taken along the line AA of FIG. 2 (a), a thick portion 16 extending in the axial direction is formed on the inside of the housing 4, and the wall An air intake 10 having a circular cross section is formed so as to cut out the thick portion 16 in the axial direction.
The injection port 8 is connected to the air intake port 10 and is formed so that its cross-sectional shape is along the outer peripheral surface of the housing 4 (in contact with the cylindrical surface).
The cross-sectional area of the air intake 10 is preferably set larger than the cross-sectional area of the injection port 8.
Hereinafter, the air intake port 10 and the injection port 8 are collectively referred to as “inlet”.
As described above, the inlet and the internal space 4c of the housing 4 are partitioned (partitioned) so that the air current cannot be transferred.

The nozzle connection port 12 is also formed in the thick portion 16 like the air intake port 10, and each nozzle hole 4 b communicates with the nozzle connection port 12.
Each nozzle hole 4 b is positioned in the vicinity of the downstream side of the injection port 8 in the injection direction, and is formed so that the discharge direction is along the injection direction of the injection port 8.
That is, each nozzle hole 4b is formed so as to accelerate a cleaning medium flying by a swirling airflow (described later) formed by air ejected from the ejection port 8 by discharging compressed air.
A female screw is formed in the upper part of the nozzle connection port 12, and a plug of an air hose of an air compressor (not shown) is connected thereto.
The acceleration configuration (assist configuration) using compressed air is not always necessary, and is additionally provided in consideration of conditions such as the type of cleaning medium and the type of dirt on the cleaning target.

  In the present embodiment, the thick portion 16 is formed to form the air intake port 10 and the injection port 8, but they may be formed by sheet metal processing.

As shown in FIG. 2A, the diameter D of the cleaning medium discharge port 14 is set smaller than the bottom diameter of the housing 4 in order to increase the suction force when discharging unnecessary cleaning medium.
The size of the cleaning medium discharge port 14 is set to have an opening area that allows the cleaning medium to pass through without clogging.
A ring-shaped lower seal member 18 having flexibility is provided around the cleaning medium discharge port 14 so that the contact with the bottom surface of the container can be kept airtight.
When a close contact state is obtained between the bottom surface of the housing 4 and the bottom surface of the container, the lower seal member 18 is not necessary.

Based on FIG. 3, the structure of the dry cleaning apparatus using the dry cleaning device 2 and the cleaning method in the container will be described.
In addition, it demonstrates with the example using the dry-type cleaning device 2 which does not have the acceleration structure by compressed air.
The dry cleaning apparatus 20 is a flexible suction device having a dry cleaning device 2, a suction unit 22 such as a dust collector, and one end connected to the suction port 6 of the dry cleaning device 2 and the other end connected to the suction port of the suction unit 22. Hose 24.
As the suction means 22, in a familiar example, the main body of a household or commercial vacuum cleaner can be used.
As shown in FIG. 3, in this embodiment, a wide-bottle container 26 having a large diameter on the bottom side is exemplified as the object to be cleaned.

A method for cleaning the inside of the container 26 by the dry cleaning apparatus 20 will be described.
The operator first puts the cleaning medium 28 into the container 26. Here, a synthetic resin flaky material is used as the cleaning medium.
As the type and amount of the cleaning medium, the optimum type and amount are determined in advance by experiments according to the material of the object to be cleaned and the type of foreign matter (dirt), and are selected based on this.
Next, as shown in FIG. 3A, the dry cleaning device 2 is inserted into the container 26. At this time, the lower seal member 18 disposed on the bottom surface of the housing 4 is inserted to a position where it contacts the bottom surface of the container without any gap.
At this time, a circular space 29 is formed between the outer peripheral surface of the housing 4 and the inner peripheral surface of the container 26 as a space for the cleaning medium 28 to fly.

The “circular space” means a space continuously connected around the casing 4.
Next, the upper seal member 30 closes the upper surface of the container 26 and the housing 4 to ensure airtightness in the container.
Next, the suction means 22 is operated, and the inside of the housing of the dry cleaning device 2 is set to a negative pressure.
The internal space 4c of the housing 4 and the internal space (circumferential space) of the container 26 are connected via a large number of holes 4a, and airtightness is maintained by the upper seal member 30, so that the inside of the container also has a negative pressure. .
When the inside of the container becomes negative pressure, air flows into the container from the air intake port 10 opened to the atmosphere through the inlet, and is rectified in the tangential direction of the housing 4 as indicated by an arrow B in FIG. Is injected.

As shown in FIG. 3A, the air flow injected from the inlet becomes a swirling air flow 32 in the container, and the cleaning medium 28 previously placed in the container is caused to fly.
The cleaning medium 28 circulates and fly on the outer peripheral side of the swirling air flow 32, that is, on the inner peripheral surface side of the container by centrifugal force. Since the outer peripheral side of the swirling airflow 32 has a higher peripheral speed than the inner peripheral side, the cleaning medium 28 repeats the swirling operation while colliding with the inner wall of the container at a high speed.
As a result, the foreign matter on the entire surface of the container where the swirling airflow 32 is generated is removed. The container 26 in the present embodiment includes a small-diameter neck portion and a large-diameter main body portion, and the inner wall is bent in the height direction, but the cleaning medium 28 hits the entire inner wall throughout the height direction, and foreign matter ( Dirt) is removed.
The above removal function can be obtained in the same manner even when the curved shape bulges outward like a teapot.
That is, the foreign substance removal function by the cleaning medium 28 is not affected by the cross-sectional shape of the circumferential space 29.

The removed foreign matter passes through the porous member (side surface of the housing 4) and is discharged to the suction means 22. At this time, since the inside of the container 26 has a negative pressure, the possibility that the cleaning medium and the foreign matters are scattered is extremely low as compared with a blasting method using compressed air.
When the cleaning is completed, as shown in FIG. 3 (b), the dry cleaning device 2 is pulled up with the suction means 22 in operation, and the cleaning medium discharge port 14 is separated from the bottom surface of the container 26.

The seal on the upper surface side of the container 26 is released and the cleaning medium discharge port 14 is opened, so that external air enters from the upper part of the container 26 and flows into the housing 4 from the cleaning medium discharge port 14. E occurs.
By this exhaust airflow E, the cleaning medium used for cleaning and the undischarged foreign matter are sucked and discharged out of the container.
Since this discharge function occurs at the same time as the lifting operation of the dry cleaning device 2, the cleaning medium and the undischarged foreign matter are completed simply by pulling up.
By such a procedure, the inside of the container can be washed strongly without using water or a solvent.

As shown in FIG. 1, you may make it discharge compressed air from the nozzle hole 4b in the same direction as an inlet at high speed.
When an assist configuration by compressed air is added, as shown in FIG. 2B, the swirling airflow caused by the airflow flowing from the inlet is further accelerated by the discharged airflow C from the nozzle hole 4b, and the flow velocity of the swirling airflow is improved. As a result, the cleaning ability in the container can be improved.

As shown in FIG. 4, if the thickness t of the upper seal member 30 is increased, it is possible to deal with containers 26A and 26B having different heights without changing the size of the housing 4.
Further, if the width W of the upper seal member 30 is increased, it is possible to deal with containers having different opening sizes without changing the size of the housing 4.

FIG. 5 shows a second embodiment.
In addition, the same part as the said embodiment thru | or the part which can be equated is shown with the same code | symbol, Unless otherwise required, the description on the structure and function which were already demonstrated is abbreviate | omitted, and only a principal part is demonstrated (in following other embodiment) the same).
In the case of the first embodiment, the position at which the cleaning medium flies may be biased depending on conditions such as the shape (particularly depth) of the container.
If the flying position of the cleaning medium is biased, cleaning unevenness occurs, which is not desirable.
The object of the present embodiment is to prevent the occurrence of such cleaning unevenness and to clean even a deep-bottomed container without unevenness.

In the dry cleaning device 34 according to the present embodiment, a hollow (cylindrical) shielding member 36 that shields an arbitrary position (part) of the injection port 8 is formed in the air intake port 10 as a vertical hole having a cylindrical shape. Is provided.
The shielding member 36 is provided so as to be movable in the axial direction (vertical direction) of the housing 4 (synonymous with being slidable or slidable).
Since the shielding member 36 is cylindrical, ventilation of the air intake port 10 in the inlet in the vertical direction is not hindered.
The shielding member 36 can freely change the position where the ejection port 8 is shielded by the shielding member moving means. In this embodiment, the string 38 is connected to the shielding member 36 as the shielding member moving means, and the position is adjusted by pulling up or loosening.

The shielding member 36 is constantly applied with a suction airflow in a direction away from the upper surface of the air intake port 10 (downward). Therefore, the position is fixed by the string 38, and when it is desired to move downward, the string is loosened and fed.
If it is desired to move it upward, the position can be moved by pulling the string 38.
The string 38 may be controlled manually or automatically by a winding mechanism connected to a motor.

A cleaning method using the dry cleaning device 34 will be described.
The operator first puts the cleaning medium into the container 26. The dry cleaning device 34 is then inserted into the container. Next, the upper seal member 30 closes the upper surface of the container 26 and the housing 4 to ensure airtightness in the container.
The cleaning operation is performed as in the above embodiment.
Since a part of the injection port 8 is shielded by the shielding member 36, the flow velocity of the swirling airflow generated in the container is lower than the other positions at the height where the shielding member 36 is located (black arrow).

As a result, the cleaning medium ejected from the high-speed swirling airflow is biased and flies to the swirling airflow position at the reduced flow velocity, and as a result, the position where the cleaning medium flies can be controlled by the shielding member 36.
By moving the shielding member 36 up and down within the inlet, the cleaning medium can be applied uniformly to the entire inner surface of the container.
The cleaning medium can be used in such a manner that the cleaning medium is concentrated at a place where the cleaning medium is to be applied with care, instead of causing the cleaning medium to fly uniformly.
By such a procedure, even inside a deep bottom container, the inside of the container can be washed strongly without using water or a solvent.

If the size of the upper seal member 30 described above cannot be used, various types of containers can be cleaned by preparing a dry cleaning device having a housing having a size corresponding to the inner diameter and depth of the container. It becomes.
In this case, it is only necessary to replace only the dry cleaning device as the dry cleaning apparatus.

6 and 7 show a third embodiment.
In each of the above embodiments, an example in which a container having a bottom is used as an object to be cleaned has been shown, but in this embodiment, it is possible to clean any part inside a long tubular body such as a duct or a clay pipe. It is aimed.
As shown in FIG. 6, the dry cleaning device 40 according to the present embodiment divides the surrounding space 44 in an airtight state at any position inside the tubular body 42 at both axial ends of the housing 4 in the axial direction. The slidable seal members 44 and 46 are integrally provided.
A suction pipe (suction hose) 48 extending in the axial direction and connected to the suction means 22 outside the tubular body 42 is connected to the intake port 6.
An air supply pipe 50 extending in the axial direction and opened to the atmosphere outside the tubular body 42 is connected to the air intake 10.

Since the space in which the cleaning medium flies is maintained at a negative pressure by the suction means 22, the cleaning medium and the removed foreign matter are not scattered even if the sealing members 44 and 46 are not strictly airtight.
The dry cleaning device 40 is moved in the pipe by a driving means (not shown) to dry-clean the inner surface of the pipe.
The dry cleaning device side of the suction tube 48 may be formed of a hard tube, and the portion may be held in and out by hand.

Cleaning the inside of the pipe has a large cleaning area, and it is necessary to clean a portion that is out of the reach of the operator.
The cleaning medium used by the dry cleaning device is dirty, destroyed, or discharged when used for a long time, so it is desirable to replace it periodically, but return the dry cleaning device to the operator for replacement. Is inefficient.
Therefore, there is a need for a function that allows the cleaning medium to be replaced even if the worker is at a distance.
In this embodiment, there is provided means for discarding the used cleaning medium from the side of the housing and replenishing a new cleaning medium from the inlet.
As shown in FIG. 7, a cleaning medium discharge port 52 is formed on the side surface of the housing 4, and the cleaning medium discharge port 52 is opened and closed by a lid member 54 supported so as to be opened and closed by a hinge. Yes.

The procedure of the cleaning medium replacement operation will be described.
FIG. 7A shows a state in which the cleaning medium is flying due to the swirling airflow.
After use for a certain period of time, the cleaning medium is discharged first in order to replace the cleaning medium. As shown in FIG. 7B, the lid member 54 covering the cleaning medium outlet 52 opens to the outside and simultaneously closes the flow path of the swirling airflow.
Then, since the swirling airflow is dammed by the lid member 54 and guided to the internal space of the housing, the cleaning medium flying on the swirling airflow quickly moves to the internal space of the housing.
Since the internal space of the housing is connected to the suction means 22 through the air inlet 6 and the suction hose 48, the cleaning medium is directly discharged into the suction means outside the pipe.
The usage time of the cleaning medium is appropriately determined according to the material and shape of the cleaning medium and the type of the object to be cleaned.

As shown in FIG. 7C, the lid member 54 is closed when the discharge of the cleaning medium is completed.
The lid member 54 may be opened and closed by an electric motor or an actuator using compressed air provided in the dry cleaning device and controlled and moved from the outside.
Alternatively, a brake wire may be connected, and the wire may be routed along the suction hose 48 to the operator's hand outside the tube and controlled manually.

A new cleaning medium is then replenished to the dry cleaning device.
As shown in FIG. 6, a required amount of the cleaning medium is put into one end of the air supply pipe 50 (air intake tube) by the cleaning medium supply means 56.
The cleaning medium reaches the inlet through the tube by the suction airflow, and is transported from the inlet to the flow path (circulating space) of the swirling airflow.
At this time, it is assumed that the cleaning medium has a shape that does not close inside the inlet.
The air supply pipe 50 and the cleaning medium supply unit 56 constitute a cleaning medium supply unit that supplies the cleaning medium from the outside of the housing so as to be able to fly in the surrounding space.
In addition to the inlet, a tube for supplying a cleaning medium may be arranged. In this case, the air intake port of the inlet need not be routed to the operator's hand, and may be open to the outside of the seal member.
By repeating such cleaning, discharging, and supplying, high-quality pipe cleaning can be realized.
