Abstract

PROBLEM TO BE SOLVED: To successively and efficiently wash the whole surface of a filter medium of a thick filter by installing the thick filter and an ultrasonic oscillator face to face in a washing tank and moving the ultrasonic oscillator while adjusting the relative distance between them in a state the ultrasonic waves are oscillated from the ultrasonic oscillator. SOLUTION: In the case a thick filter F for removing dust is to be washed, a thick filter F is fixed in a washing tank 2 and then an ultrasonic oscillator S is moved. That is, while ultrasonic waves being emitted to the to-be-washed face of the thick filter F from the ultrasonic oscillator S, the oscillator S is moved to the right side from a standard position and simultaneously to the front side and then moved to the left side and again moved to the right side and simultaneously to the rear side and finally moved to the left side. After that, the oscillator is moved to the lower side, and the same movement is carried out to successively wash the thick filter F by ultrasonic waves. In other words, by changing the relative distance between the thick filter F and the ultrasonic oscillator S, dust adhered to the filtration medium is scraped off and the thick filter F is successively washed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for ultrasonically cleaning a thick filter for removing dust and the like, and more particularly to a cleaning device such as a medium-performance filter and a filter for preventing salt damage.

2. Description of the Related Art Hitherto, filters have been used in all fields of industry to remove dust and the like.
For example, a filter called a medium-performance filter or a filter for preventing salt damage is used for air conditioning of buildings and underground shopping malls, and for air supply of gas turbines for private power generation. As these filters, thick filters having a relatively large thickness are employed in order to remove salts, dust, oil, fiber dust and the like from the air and to exert a sufficient filtering effect.

FIG. 12 shows an example of this thick filter.
As shown in the perspective view showing the form of the filter medium in the thick filters (a) and (b), there is a filter having a length of about 600 mm, a width of about 600 mm and a thickness of about 300 mm. In the example of the thick filter F shown in the sectional view of FIG. 12 (a), many folds 82
A filter member 82 made of a nonwoven fabric of resin fibers and glass fiber or the like formed with a is provided by being bent in the thickness direction of the mold frame 81. By bending the filter member 82 in this way, the filtration surface area is increased to increase the filtration surface area. It is formed so as to exhibit a filtering effect.

In the example of the thick filter F shown in FIG. 12 (b), a filter material 86 is provided by bending in the thickness direction of a mold 85, and the filter material 86 is vertically folded between the bent filter materials 86. By providing the separator 87 provided with the folds 87a, the filter is formed so that the filtration surface area is increased and a uniform filtration effect can be exhibited.

As an ultrasonic cleaning device for cleaning such a filter, there is a device described in Japanese Utility Model Registration No. 2540949 filed earlier by the present applicant. In this device, FIG. As shown in FIG.
13 using the time waveform of the ultrasonic wave 92 emitted from FIG.
As shown in (b), the cavitation C generated by the standing wave attempts to remove dust and the like attached to the filter 93.

However, as described above, in the thick filter F, the structures of the filter media 82 and 86 and the separator 87 are complicated, and even if the filter is soiled, the folds are bent using a brush or the like. Since the insides of 82a and 87a cannot be cleaned, a short one is
The used thick filter F is replaced with a new thick filter F at intervals of about once every three months, and the used thick filter F is discarded. Therefore, a large cost is required for the maintenance of the thick filter that can be replaced in a short cycle. Moreover, such disposal of industrial waste is incompatible with the recent reuse of effective resources.

[0007] Further, even if such a thick filter F is to be cleaned using the device described in the above-mentioned utility model registration No. 2540949, the present invention is intended for a relatively thin filter. Not suitable for cleaning.

Therefore, there is a need for a means for cleaning and reusing such a thick filter F.

[0009]

Therefore, in order to solve the above-mentioned problems, the invention according to this application provides a thick filter and an ultrasonic vibrator in a cleaning tank so as to face each other. By moving while adjusting the relative distance between the thick filter and the ultrasonic vibrator while emitting ultrasonic waves, the entire filter medium of the thick filter is sequentially washed by the cavitation phenomenon caused by ultrasonic waves. ing.

As described above, by performing ultrasonic cleaning while adjusting the relative distance between the thick filter and the ultrasonic vibrator in the cleaning tank, it is possible to remove dirt inside the filter medium having a predetermined thickness. Therefore, the thick filter can be cleaned and reused.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning method for ultrasonically cleaning a thick filter for removing dust and the like, and more particularly to a medium-performance filter, a filter for preventing salt damage and the like. it relates ultrasonic cleaning method of the thickness-shaped filter for relatively successively ultrasonic cleaning dust and the like adhering to the thick section filter with a thickness.

[0002]

2. Description of the Related Art Hitherto, filters have been used in all fields of industry to remove dust and the like.
For example, a filter called a medium-performance filter or a filter for preventing salt damage is used for air conditioning of buildings and underground shopping malls, and for air supply of gas turbines for private power generation. As these filters, thick filters having a relatively large thickness are employed in order to remove salts, dust, oil, fiber dust and the like from the air and to exert a sufficient filtering effect.

FIG. 12 shows an example of this thick filter.
As shown in the perspective view showing the form of the filter medium in the thick filters (a) and (b), there is a filter having a length of about 600 mm, a width of about 600 mm and a thickness of about 300 mm. In the example of the thick filter F shown in the sectional view of FIG. 12 (a), many folds 82
A filter member 82 made of a nonwoven fabric of resin fibers and glass fiber or the like formed with a is provided by being bent in the thickness direction of the mold frame 81. By bending the filter member 82 in this way, the filtration surface area is increased to increase the filtration surface area. It is formed so as to exhibit a filtering effect.

In the example of the thick filter F shown in FIG. 12 (b), a filter material 86 is provided by bending in the thickness direction of a mold 85, and the filter material 86 is vertically folded between the bent filter materials 86. By providing the separator 87 provided with the folds 87a, the filter is formed so that the filtration surface area is increased and a uniform filtration effect can be exhibited.

As an ultrasonic cleaning device for cleaning such a filter, there is a device described in Japanese Utility Model Registration No. 2540949 filed earlier by the present applicant. In this device, FIG. As shown in FIG.
13 using the time waveform of the ultrasonic wave 92 emitted from FIG.
As shown in (b), the cavitation C generated by the standing wave attempts to remove dust and the like attached to the filter 93.

[0006]

However, as described above, in the thick filter F, the structures of the filter media 82 and 86 and the separator 87 are complicated, and even if the filter is soiled, the folds are bent using a brush or the like. Since the insides of 82a and 87a cannot be cleaned, a short one is
The used thick filter F is replaced with a new thick filter F at intervals of about once every three months, and the used thick filter F is discarded. Therefore, a large cost is required for the maintenance of the thick filter that can be replaced in a short cycle. Moreover, such disposal of industrial waste is incompatible with the recent reuse of effective resources.

[0007] Further, even if such a thick filter F is to be cleaned using the device described in the above-mentioned utility model registration No. 2540949, the present invention is intended for a relatively thin filter. Not suitable for cleaning.

Therefore, there is a need for a means for cleaning and reusing such a thick filter F.

[0009]

Therefore, in order to solve the above-mentioned problems, the invention according to this application provides a thick filter and an ultrasonic vibrator in a cleaning tank so as to face each other. By moving while adjusting the relative distance between the thick filter and the ultrasonic vibrator while emitting ultrasonic waves, the entire filter medium of the thick filter is sequentially washed by the cavitation phenomenon caused by ultrasonic waves. ing.

As described above, by performing ultrasonic cleaning while adjusting the relative distance between the thick filter and the ultrasonic vibrator in the cleaning tank, it is possible to remove dirt inside the filter medium having a predetermined thickness. Therefore, the thick filter can be cleaned and reused.

[0011]

If the filter material is selectively moved by a moving amount that can be cleaned in opposition to the cleaning surface, the entire surface of the filter medium of the thick filter can be effectively ultrasonically cleaned. The thickness direction of the thickness-shaped filter This is a direction passing through the fluid, is also a thick filter medium for removing dust and the like from the fluid passing through is provided.

[0012] As this, it is opposed to the filtering material and the ultrasonic vibrator thick section filter in a cleaning tank, the relative distance between the filtration material of thick section filter while emitting ultrasonic waves from the ultrasonic vibrator As the standing wave generated by the ultrasonic wave emitted from the ultrasonic transducer causes the cavitation phenomenon and removes dust and the like attached to the filter medium, the filter medium of the thick filter is sequentially washed in the thickness direction. it can be made possible to reuse the thick sections filters washed <br/> Kiyoshi.

Further, the thick filter opposed to the ultrasonic vibrator for emitting ultrasonic waves in the cleaning tank is moved in the thickness direction of the thick filter so that the relative distance between the filter and the ultrasonic vibrator is increased. While adjusting the thickness of the thick filter in the vertical or horizontal direction .
Even if the filter is selectively moved by a moving amount that can be cleaned in opposition to the cleaning surface, the entire surface of the filter medium of the thick filter can be effectively ultrasonically cleaned.

Further, if ultrasonic waves are alternately emitted from the ultrasonic transducers disposed opposite to both the front and rear surfaces of the thick filter for cleaning, the cleaning effect can be further improved by ultrasonic cleaning from both sides. it can.

However, the ultrasonic transducers S formed so as to be able to face a part of the thick filter F may be used. The arrangement is not limited.

The ultrasonic vibrator S emits ultrasonic waves while being opposed to the thick filter F in the cleaning tank 2 as shown in FIG. vertical direction by T _1, the left-right direction, and is configured so as to be movable to an arbitrary front-rear direction (a direction relative distance close to or away from the ultrasonic transducer S is changed).

A guide groove 4 is formed in the vertical direction on the back surface of the ultrasonic transducer S, and a guide portion 5a of the vertical guide 5 is formed.
Is configured to be able to move up and down along. The ultrasonic transducer S is moved up and down by a known screw mechanism or the like by rotating the shaft 7 by a drive motor 6 provided on the vertical guide 5 in this vertical movement.

A guide groove 5b is formed in the back of the vertical guide 5 in the horizontal direction, and is configured to be able to move laterally along the guide portion 8a of the horizontal guide 8. In this lateral movement, if the shaft 10 is rotated by the drive motor 9 provided in the lateral guide 8, the vertical guide 5 is moved laterally by a known screw mechanism or the like.

Further, guide grooves 8b are provided on both sides of the lateral guide 8 in the front-rear direction, and are configured to be able to move back and forth along a front-rear guide 11 provided on the main body 1. This back and forth movement is caused by the drive motor 12 provided in the main body 1.
When the shaft 13 is turned, the lateral guide 8 is moved back and forth by a known screw mechanism or the like.

The movement of these ultrasonic transducers S is controlled by a control panel 13 provided on the side of the main body 1. The amount of movement of the ultrasonic transducer S is controlled by the rotation angles of the drive motors 6, 9, 12 and the like. Further, an oscillator, a transformer, and the like for controlling the wavelength of the ultrasonic wave emitted from the ultrasonic transducer S are provided inside the main body 1.
The control panel 13 is configured to be controllable.

The control panel 13 may be configured to automatically monitor the water temperature and the amount of water in the cleaning tank 2 or the dirt of the cleaning liquid, depending on the type of the thick filter F to be cleaned and the degree of dirt. What is necessary is just to set suitably.

According to thick section ultrasonic cleaning apparatus W ₁ filter configured as described above, after fixing the thick section filter F into the cleaning tank 2, the operation described in FIG. 3 (a), (b) By moving the ultrasonic vibrator S as shown in the block diagram and the movement diagram, the relative distance to the thick filter F is adjusted so that the filter media 82 and 86 (FIGS. (b) The thick filter F provided with (2) can be subjected to ultrasonic cleaning.
In this example, the description will be made with the upper left rear portion of the movement diagram shown in (b) as the reference position.

E) After moving to the lower side, f) performing the above a) to d) to perform ultrasonic cleaning. Then g) move up and return to the starting point of one step. As a result, the cleaning of the thick filter F is completed, and the cleaned thick filter F is discharged by the transfer means or the like. After that, h) perform the above a) to d), and i)
The thick filter F can be sequentially washed by repeating the above e).

The moving amount of the ultrasonic vibrator S to be moved in this manner is such a moving amount that the ultrasonic vibrator S can clean the entire surface of the thick filter F in the width direction and the vertical direction. The direction is controlled by the amount of movement determined based on the thickness of the filter media 82 and 86 of the thick filter F and the wavelength of the ultrasonic wave.

Thereafter, i) the above-mentioned b) to e) are performed, j) the upper side is moved to the upper side, and k) the thick filter F is sequentially washed by repeating the above b) to e).

FIGS. 6 (a) and 6 (b) are a block diagram and a movement diagram showing another operation description. In this example, the lower right front part of the movement diagram shown in (b) is set as a reference position. In a state where ultrasonic waves are emitted from the ultrasonic vibrator S toward the cleaning surface of the thick filter F, a) move rearward and upward from the reference position, b) move leftward, and c) move forward. Move to the right, d) then move to the right, e) then move to the back, f) then move down, g) and then b) to e)
And h) successively cleaning the thick filter F by repeating the above a).

FIGS. 7A and 7B are a block diagram and a movement diagram showing still another operation explanation. In this example, the lower left front part of the movement diagram shown in FIG. In a state where ultrasonic waves are emitted from the ultrasonic transducer S toward the cleaning surface of the thick filter F, a) the upper right rear side is moved from the reference position, b) the left side is moved, and c) the next Move to the right front, d) then move to the left, e) then move to the right rear, upper, f) then move to the left, g)
