the k value of the second metal separator 35 is 4mm, the ultrasonic frequency of the ultrasonic transducer 36 on the second metal separator 35 is 21.3kHz,
the k value of the third second metal separator 35 is 2mm, the ultrasonic frequency of the ultrasonic transducer 36 on the third second metal separator 35 is 27.1kHz,
the last second metal separator 35 is a fourth second metal separator 35, the k value of the fourth second metal separator 35 is 0mm, and the ultrasonic frequency of the ultrasonic transducer 36 on the fourth second metal separator 35 is 20.5kHz;
the first electromagnet 322 is intermittently electrified, and periodically and reciprocally conducted according to the period of 2-3 s of the first current, 3-5 s of the power off, 2-3 s of the second current and 3-5 s of the power off, the first electromagnet 322 is connected with the first current to generate magnetic force which is repulsed with the permanent magnet 321, the first electromagnet 322 is connected with the second current to generate magnetic force which is repulsed with the permanent magnet 321, and the permanent magnet 321 drives the tail end of the flexible tube 32 to swing; while the end of the flexible tube 32 is in the process of swinging, the end of the flexible tube 32 is in intermittent contact with the water surface of the water layer 38.
In the present invention, the suction pump can form a very large initial negative pressure on the end of the S-shaped channel 37 through the suction pipe 34, mainly because the lower end of the last second metal partition 35 is flush with the initial water surface of the water layer 38, then under the combined action of the knocking of the electromagnetic knocking cylinder 50 and the ultrasonic vibration, the water surface of the water layer 38 forms regular waves, the waves are high and stable and distributed uniformly, and the lower ends of the 1 st to 4 th second metal partition 35 can be submerged at the wave crest of the waves, which promotes the air flow containing dust to have enough time and enough contact area, thereby improving the purifying effect of the air flow containing dust by the water. The wave trough height can be lower than the lower end of the 1 st to 4 th second metal partition plates 35, so that the S-shaped channel 37 forms a smooth channel, and the air flow containing dust is convenient to circulate.
It should be noted that if the S-shaped channel 37 is always a complete and unobstructed channel, the contact between the dust-containing air flow and water is limited, and even if the k value is always kept at 1mm, the filtering effect is limited, and more second metal separators 35 must be provided to increase the filtering effect by limiting the amplitude. Further, if the k value is smaller, it is not significant, and as the amount of dust deposited in the water increases, the water surface is raised by 1mm quickly, and the lower end of the second metal separator 35 is blocked.
In the present invention, in a short time, even if the water surface is lifted to within 10mm, since the water surface is always in the presence of waves, even if the water surface is submerged for a part of the time by the lower end of the second metal separator 35, the trough of the waves is short in a gap between the lower end of the second metal separator 35 through which the air flow passes, so that the air flow containing dust is dynamically balanced between circulation and filtration.
Comparative example 1
In this example, the difference from example 3 is that all k values are always kept at 1mm, the number of second metal separator 35 and first metal separator 33 is 4, electromagnetic knocking cylinder 50 is not started, and the rest is the same as example 3, and the final dust removing effect is shown in table 1.
Comparative example 2
In this example, the difference from example 3 is that all k values are always kept at 1mm, 10 second metal separators 35 and 10 first metal separators 33 are used, the electromagnetic knocking cylinder 50 is not started, and the rest is the same as example 3, and the final dust removing effect is shown in table 1.
Comparative example 3
In this example, the difference from example 3 is that all k values are always kept at 1mm, 15 second metal separators 35 and 15 first metal separators 33 are provided, the electromagnetic knocking cylinder 50 is not started, and the rest is the same as example 3, and the final dust removing effect is shown in table 1.
Comparative example 4
In this example, if only the electromagnetic knocking cylinder 50 is activated, none of the ultrasonic transducers 36 are activated, and the rest is the same as in example 3, the final dust removing effect is shown in Table 1.
Comparative example 5
In this example, if only the ultrasonic transducer 36 is activated, the electromagnetic knocking cylinder 50 is not activated, and the final dust removing effect is the same as that of example 3, as shown in Table 1.
Comparative example 6
In this example, the difference from example 3 is that all k values are always kept at 1mm, the remainder being the same as example 3, and the final dust removal effect is shown in Table 1. Because the waves are too dense to block the lower end of the second metal separator 35 and too long to block, the waves are caused to fluctuate more severely and irregularly at the moment of smooth negative pressure adsorption, and some air flow containing dust escapes, so that the dust content in a part of the air flow finally discharged is higher.
Comparative example 7
In this example, the difference from example 3 is that all k values are always kept at 3mm, and the rest is the same as example 3, and the final dust removal effect is shown in Table 1.
Comparative example 8
In this example, the difference from example 3 is that the ultrasonic frequencies of all ultrasonic transducers 36 were 20kHz, and the rest was the same as example 3, and the final dust removal effect is shown in table 1.
Comparative example 9
In this example, the difference from example 3 is that the ultrasonic frequencies of all ultrasonic transducers 36 are 27.1kHz, and the rest is the same as example 3, and the final dust removal effect is shown in table 1.
Comparative example 10
In this example, the difference from example 3 is that all the electromagnetic knocking cylinders 50 were replaced with another set of ultrasonic transducers each having an ultrasonic frequency of 20kHz, and the rest is the same as example 3, and the final dust removing effect is shown in table 1.
TABLE 1
The dust removal efficiency is the difference between the dust concentration at the suction cup and the dust concentration at the exhaust end of the suction pump and the percentage of the dust concentration at the suction cup; which is the average of 10 measurements. The highest dust concentration at the exhaust end of the getter pump is the maximum measured in 20 random measurements.
In the invention, the electromagnetic knocking cylinder 50 is used for knocking the side wall of the metal box 31 by upward movement of the magnetic ball 52 under the action of the electromagnet II 53 and then rolling down under the action of gravity; finally, under the action of repulsive magnetic force, knocking upwards, and resetting again; and the process is repeated in a circulating way. The knocking mainly generates vibration with larger amplitude, and dense vibration with small amplitude generated by matching with ultrasonic vibration is superimposed, so that the waves have wave height and wave speed fluctuation, and the final effect is optimal. The diaphragm spring 55 and the elastic sealing layer 54 are selected to cushion based on the limitation of the installation space.
While the end of the flexible tube 32 is in intermittent contact with the water surface of the water layer 38 during oscillation, this allows a substantial portion of the dust-laden air stream to initially enter the water surface and then settle, thereby helping to enhance subsequent cleaning.
In addition, the vibration generated by the ultrasonic transducer 36 and the swinging of the end of the flexible tube 32 also prevent a large amount of dust from adhering to some extent.

Next, every 3 to 5 hours, a lower orifice plug 312 is opened to drain the rising water surface from the overflow port so that the fluctuation in the liquid level of the water layer 38 is not too large.
Finally, when the sewage and dirt in the metal box 31 need to be discharged, the valve 311 is opened for discharging the sewage. And then backwashed from valve 311.
