Dust collected not only on the surface but also on the inside can be lifted and removed from the roll filter. At this time, since no external force is locally applied to the roll filter, the roll filter is not damaged.

Embodiment FIG. 1 is a block diagram of a roll filter cleaning apparatus according to an embodiment of the present invention.
First, each element constituting the roll filter cleaning device will be described with reference to FIG.
In addition, the roll filter 3 is produced from the nonwoven fabric, and the dust in the air is collected in the hole. The roll filter 3 has a width of 1 m, a thickness of about 1 cm, and a length of 15 m to 20 m. However, the width, thickness, and length do not limit the application of the present invention, but are illustrated for easier understanding of the present invention.

The pre-cleaning roll filter feeding machine 1 is composed of a base 2 placed on the floor, and two pillars 4 that are separated from the base 2 by a little larger than the width of the roll filter 3 to be cleaned. And the bearing part 6 which supports the both ends of the mandrel 5 around which the roll filter 3 to be cleaned is wound around the tip of the column 4 so that the roll filter 3 is positioned horizontally is provided.
The detergent penetration tank 8 is a bottomed 1.5 m square cubic tank placed on the floor, and can store an alkaline detergent. An ultrasonic vibrator 9 is inserted into the bottom. By vibrating the ultrasonic vibrator 9, cavitation occurs on the surface and inside of the roll filter 3, and dust can be lifted from the roll filter 3. .

The cleaning unit 11 includes two cleaning agent sprays 12 and 13 for spraying the cleaning agent on both surfaces of the roll filter 3 at a high speed, a rinse spray 14 for spraying a rinsing rinse after the cleaning agent is sprayed, and a narrow gap. The cleaning agent draining device 17, the cleaning agent sprays 12 and 13, the rinse spray 14 and the cleaning agent draining device 17, each of which includes two opposing draining rollers 15 and a motor 16 that rotates one draining roller 15. The partition plate 18 is recovered by receiving the rinse and returned to the cleaning agent permeation tank 8. The partition plate 18 is an upwardly convex chevron plate.
Since the partition plate 18 is provided in this manner, the cleaning agent and the rinse can be received, so that they can be prevented from scattering.

The rinsing tank 20 is a bottomed 1.5 m square cubic tank placed on the floor and stores water. An ultrasonic vibrator 9 is inserted at the bottom, and cavitation occurs on the surface and inside of the roll filter 3 by vibrating the ultrasonic vibrator 9, and the remaining dust and cleaning agent are submerged in water. To be stirred.
The sterilizing agent spray 21 is a spray that sprays the sterilizing agent on the roll filter 3 pulled up from the rinsing tank 20.
The rinsing draining device 23 includes two draining rollers 15 facing each other through a narrow gap and a motor 24 that rotates one draining roller 15, and is included in the roll filter 3 that is rinsed and sprayed with a sterilizing agent. Squeeze the water.
The air injector 26 injects high-speed air, blows away moisture remaining in the roll filter 3, and performs first-stage drying.
The cleaned roll filter winder 28 has two vertical members on a stand 30 that supports both ends of a winding mandrel 29 for winding the cleaned roll filter so that the cleaned roll filter is horizontal. It comprises a column 31 and a third motor 32 that rotates the winding mandrel 29.
As will be described later, the control device 34 controls the rotational speeds of the first motor 16, the second motor 24, and the third motor 32 to adjust the moving speed of the roll filter 3.

In the roll filter cleaning device, the pre-cleaning roll filter delivery machine 1, the cleaning agent permeation tank 8, the rinsing tank 20, and the cleaned roll filter winder 28 are arranged in a straight line on the floor in this order. The cleaning agent penetration tank 8 and the rinsing tank 20 are arranged next to each other.
Moreover, the partition plate 18 is arrange | positioned above the place where the washing | cleaning agent penetration tank 8 and the rinse tank 20 were adjacent.
A cleaning unit 11 is disposed in the vicinity of the partition plate 18 above the cleaning agent permeation tank 8. In the cleaning unit 11, two cleaning sprays 12 and 13 are disposed at a height closest to the upper opening of the cleaning agent permeation tank 8, a rinse spray 14 is disposed obliquely above, and obliquely upward. A cleaning agent draining device 17 is provided.

Further, a disinfectant spray 21 is disposed near the upper opening of the rinsing tank 20, and a rinse draining device 23 is disposed obliquely above.
Further, an air injector 26 is disposed between the rinsing tank 20 and the cleaned roll filter winder 28.

  Each element of the roll filter cleaning apparatus is arranged in this way, and further, rollers 36 are arranged at various places to guide the roll filter 3 to be cleaned. The roller 36a that guides the roll filter 3 fed from the pre-cleaning roll filter delivery machine 1 to the cleaning agent penetration tank 8 and the roll filter 3 is guided to a predetermined depth so that it can be immersed in the cleaning agent penetration tank 8 for a predetermined period. A roller 36b for separating the partition plate 18 and the roll filter 3 from each other with a predetermined gap, and rollers 36d and 36e for suppressing the shaking of the roll filter 3 due to air injection from the air injector 26. However, the arrangement of the roller 36 is not limited to this, and may be arranged at an appropriate position.

Next, a procedure for cleaning the roll filter 3 performed using the roll filter cleaning device will be described.
The roll filter 3 before cleaning is removed from the air conditioner while being wound around the mandrel 5 in advance. Then, the mandrel 5 is placed on the bearing portion 6 of the pre-cleaning roll filter feeder 1 and the pre-cleaning roll filter 3 is set.
Further, an alkaline detergent is poured into the detergent permeation tank 8 and water is poured into the rinse tank 20 until a predetermined depth is reached.

Next, one end of a copper foil having a thickness of approximately 0.1 mm and the same width as that of the roll filter 3 is bonded to the leading end of the roll filter 3 before washing. Then, the other end of the copper foil is passed through the same predetermined path as that for the cleaning, and is wound around the core 29 for the cleaned roll filter.
Next, the third motor 32 is rotated to wind up the copper foil first, and then the roll filter 3 to be cleaned is wound up.

The roll filter 3 to be cleaned is first immersed in the cleaning agent, and the cleaning agent penetrates into the roll filter 3 over the whole, and the dust in which the cleaning agent is collected floats from the roll filter 3. At this time, by irradiating the ultrasonic wave, the dust can be raised more.
By soaking the roll filter 3 in the cleaning agent infiltration tank 8 for a predetermined time in this way, the cleaning agent permeates the entire roll filter 3 during that time, so that not only the surface of the roll filter 3 but also the inside is captured. The collected dust can be lifted and removed from the roll filter 3.
Further, since the cleaning agent easily penetrates between the dust and the roll filter 3 by irradiating the roll filter 3 with the ultrasonic wave, it is possible to make it easier to lift the dust from the roll filter 3 and remove it. it can.

Next, the roll filter 3 is lifted from the cleaning agent permeation tank 8, and a high-speed cleaning agent jet is blown from one surface of the roll filter in which the cleaning agent has permeated throughout, so that the dust that has floated is removed from the other surface. It blows away in the direction and flows down along with the cleaning agent along the other surface.
Next, a high-speed cleaning agent jet is sprayed from the other surface, and the cleaning agent containing dust is blown off to the partition plate 18.
Since the cleaning agent is sprayed on the roll filter 3 as a high-speed jet in this way, dust is carried while the jet passes in the thickness direction of the roll filter 3, and dust collected inside the roll filter 3 can also be removed. it can.
In addition, since a high-speed jet of cleaning agent is sprayed from both sides, there is no difference in how dust is removed from the front and back.

  Next, the rinse liquid is sprayed to wash away the alkaline detergent. Thus, by spraying acidic rinse on the roll filter 3 after spraying the cleaning agent, alkali and metal soap contained in the cleaning agent can be removed.

Next, since the roll filter 3 is sent while being sandwiched between the two draining rollers 15 of the cleaning agent draining device 17, the cleaning agent contained in the roll filter 3 is squeezed. The squeezed cleaning agent returns to the cleaning agent permeation tank 8 along the partition plate 18.
Next, by immersing in the rinsing tank 20 for a predetermined time and irradiating ultrasonic waves upward from the bottom of the rinsing tank 20, water penetrates over the entire roll filter 3, and the remaining dust is water. Floated on.
Since the roll filter 3 is immersed in the rinsing tank 20 for a desired time in this way, water penetrates all over and removes remaining dust, alkali, metal soap, etc. from the roll filter 3, so that the air permeability is reduced. It can be restored to a state close to new.

Next, the disinfectant is sprayed on the roll filter 3 pulled up from the rinsing tank 20.
Next, water is squeezed between the two draining rollers 15 of the rinse draining device 23.
Finally, the water in the roll filter 3 is further blown away by the air jetted from the air jetting device 26, resulting in a semi-dry state.
In this way, a considerable proportion of the water remaining after squeezing by the rinsing drainer 23 is blown off by the air injector 26 and lightens, so that the wound roll filter 3 wound up is separately prepared in a drying furnace (not shown). Can be easily carried.

And it is wound up by the cleaned roll filter winder 28 as a cleaned roll filter.
Thereafter, the cleaned roll filter is completely dried in a drying furnace.

Next, the feed rate of the roll filter 3 in the cleaning agent draining device 17, the rinse draining device 23, and the cleaned roll filter winder 28 will be described.
Since the roll filter 3 is a non-woven fabric, when it is pulled, holes are reduced and the roll filter 3 is torn. Therefore, the moving speed of the roll filter 3 is controlled so as not to apply a pulling force. Further, it is necessary to keep the roll filter 3 immersed in the cleaning agent and water as loose as possible. If left loose, the cleaning agent and water can penetrate into the inside of the roll filter 3 to remove dust.

Therefore, the speed wound around the cleaned roll filter winder 28 is set to the slowest speed, and then the feed speed in the rinse water draining device is made slightly faster than the wind speed, and the feed speed in the cleaning agent drainer is set to a single value. It is fast. Note that the winding speed is gradually increased when the rotation speed of the third motor 32 is kept constant because the diameter of the roll filter 3 increases with winding. Therefore, the control device 34 controls the winding speed to be constant by gradually decreasing the rotation speed of the third motor 32. Note that the initial speed may be slowed so that the moving speed of the roll filter 3 at the end of winding does not exceed the speed of the second motor 24.
In this way, since a large pulling force is not applied to the roll filter 3, the roll filter 3 is not damaged.

  Further, when the moving speed of the roll filter 3 is controlled in this way, the roll filter 3 stays in the rinsing tank 20 for a long time, and the rinsing is performed more perfectly.

  In such a roll filter cleaning device, the drawn roll filter is sequentially immersed in the cleaning agent permeation tank 8 for a predetermined period, and the cleaning agent permeates the entire roll filter 3 during that time. Dust collected not only on the surface but also on the inside can be lifted from the roll filter 3 and removed. At this time, since no external force is locally applied to the roll filter 3, the roll filter 3 is not damaged.

In addition, although the cleaning agent is sprayed as a high-speed jet from both surfaces of the roll filter 3, dust that has been lifted by spraying the cleaning agent from only one surface may be blown off together with the cleaning agent.
Moreover, the cleaning agent permeation tank 8 and the rinsing tank 20 are prepared separately, and the cleaning agent permeation and rinsing are continuously performed. You may go.

It is a block diagram of the roll filter washing | cleaning apparatus of embodiment concerning this invention.
