Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an ultrasonic micro-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic micro-vibration filtering apparatus, and more particularly, to an ultrasonic micro-vibration filtering apparatus capable of effectively removing contaminants from a filter medium provided inside a filtration apparatus for filtering polluted water using an ultrasonic oscillator Invention.

Generally, in order to use a water source as drinking water, various sludge contained in a water source is filtered and purified and supplied through various stages. Particularly, in a swimming pool, tap water or ground water is used as used water, and the sludge is filtered through a filtration device without discarding it, and is recycled through chemical treatment and circulated to the swimming pool. Also, in hotels and large buildings, after tap water or ground water is used as odd water, the pollutants are filtered by filtration device and treated with clear water for reuse as cleaning water.

At this time, the filtration device is filled with the filter material such as activated carbon, anthracite, sand, gravel, etc., and the incoming water can be used as purified water after filtration through the filter material.

However, if the filters are used for a certain period of time, the pores are blocked by the foreign substances and the filtration performance is remarkably lowered. Therefore, the filtration efficiency can be maintained by partially or totally replacing the filters after 6 months to 1 year.

1, a gravel layer 51, a sand layer 53, and an activated carbon layer 55, which are filter media, are stacked in this order with a predetermined height in the filtration tank 10.

Thus, when unfiltered water is supplied through the water pump 20, it flows into the upper part of the filtration tank 10 and is filtered while passing through the activated carbon layer 55, the sand layer 53 and the gravel layer 51 in order, (15) to the lower chamber (17).

In the backwashing process, foreign materials adhering to the filter material are desorbed and discharged by washing the filter material while passing water through the gravel layer 51, the sand layer 53, and the activated carbon layer 55 in reverse order .

However, even if water is backwashed by the backwashing process, such conventional filtration apparatuses do not easily remove the foreign substances adhering firmly to the surfaces of the filter media 51, 53, and 55 over a long period of time, And the use of medicines also leads to an economic burden.

Therefore, after a certain period of time, it is necessary to replace part or all of the filter media 51, 53 and 55 in order to maintain the performance. However, the replacement work is troublesome, and the costs such as the operation cost and the material cost are inconvenient.

Recently, there has been proposed a technique of removing foreign matter adhering to the surface of the filter media 51, 53, 55 inside the tank body 110 by providing the ultrasonic vibration part 111 on the outer side of the tank body 11, .

However, the vibration of the ultrasonic vibration part 111 provided outside the tank body 11 is not uniformly transmitted to the filter media 51, 53, and 55, and thus the backwashing effect is not good.

Further, as the tank body 11 of the tank main body 11 is directly vibrated, problems such as bolts, nuts, and the like at the pipe connection portion are loosened or loosened by the vibration, .

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

The filtration apparatus of the present invention includes a filtration tank 100, a filter medium 110 filled in the filtration tank, a guide base 120, an ultrasonic oscillator 130 for generating ultrasonic vibration, a coupling cap 140, And an oscillation extension pin 150.

The filtration tank 100 is provided with an inlet port 102 through which raw water flows in an upper portion thereof and an outlet port 104 through which filtered filtrate water is discharged.

The gravel layer 112 is sandwiched between the gravel layer 112 and the activated carbon layer 116. The gravel layer 112 is sandwiched between the gravel layer 112 and the activated carbon layer 116 by a predetermined height. The anthracite layer may be further laminated.

The guide base 120 passes through the upper portion of at least one (preferably three to four) filtration tanks 100 and is vertically installed up and down to the lowermost filter medium layer. At this time, the guide base 120 may be formed of a flexible material, and the control lines may be coupled in parallel, or may be formed in a pipe shape so that the control line may be inserted into the interior.

The ultrasonic oscillator 130 is connected to the middle and the end of the control line of the guide base 120, and ultrasonic oscillation is operated by a separate control unit. That is, when power is supplied by a control line as in the prior art, energy generated by an electric signal of a high frequency is converted into mechanical energy to generate vibration. At this time, it is preferable that the ultrasonic oscillator 130 has a plurality of heights so that the ultrasonic oscillators 130 are positioned in the middle of each of the media layers 110.

The coupling cap 140 is attached to the outer side of the ultrasonic oscillator 130 and is coupled to the outer side of the ultrasonic oscillator 130. The ultrasonic oscillation expansion pin 150 transmits the vibration of the ultrasonic oscillator 130 over a wide range, And is protruded from the outer side of the body 140 in a wire shape in all four directions.

7, the inside of the guide base 120 and the ultrasonic oscillation extension pin 150 may communicate with each other as a hollow portion, and the side surface of the ultrasonic oscillation extension pin 150 A plurality of ejection holes 152 may be formed through the through holes. It is also preferable that the backwash water is supplied through the guide base 120 and is blown toward the side of the jet hole 152 formed in the ultrasonic wave oscillation expansion pin 150 so that the space between the media layers 110 is cleaned.

The heat generating unit 160 is provided in the ultrasonic oscillation extension pin 150 to generate heat and to be transmitted to the ultrasonic oscillation extension pin 150.

Hereinafter, the operation of the filtration apparatus of the present invention configured as described above will be described.

When the raw water flows into the interior of the filter 100 through the inlet 102 to filter the contaminated raw water, the raw water is supplied to the activated carbon layer 116, the sand layer 114, and the gravel layer 112, The foreign material contained in the raw water is filtered by the filter medium layer 110. The filtered water filtered by the foreign substance is discharged through the lower discharge port 104.

As described above, when the process of filtering the raw water by operating the filtration device is performed for a long time, the amount of the foreign matter filtered by the filter material layer 110 is gradually increased, which decreases the filtration rate by blocking the pores of the filter material layer 110.

Accordingly, when the filtration device is operated for a certain period of time and filtration is performed, backwashing is performed to perform the operation of discharging the foreign substances that have been collected and filtered by the filtering material layer 110. For this purpose, the valve is controlled so that water flows in the opposite direction for a certain period of time. That is, when clean backwash water is supplied to the outlet 104, the filtered backwash water is filtered by the filter medium layer 110 through the gravel layer 112, the sand layer 114, and the activated carbon layer 116 from the lower portion of the filter medium layer 110, The foreign matter is desorbed and discharged through the inlet 102.

However, there is a case where the foreign matter fixed to the filter medium layer 110 for a long time is not removed even by the backwash water. At this time, in the filtration apparatus of the present invention, power is applied to the ultrasonic oscillator 130 through the control line to oscillate the ultrasonic vibration. Of course, it is preferable that the vibration intensity of the ultrasonic oscillator 130 is such that microvibration does not cause vibration of a too large wavelength.

The vibration of the ultrasonic oscillator 130 is transmitted to the four sides of each of the media layers 110 through the ultrasonic oscillation extension pin 150 coupled by the coupling cap 140. Therefore, even with a small number of ultrasonic oscillators 130, vibration can be widely transmitted to the wide filter medium layer 110.

The fine vibration transmitted through the ultrasonic wave oscillation expansion pin 150 causes the foreign matter adhering to the filter medium layer 110 to be desorbed and the separated foreign matter is discharged together with the backwash water flowing in.

In addition, the water is heated by the operation of the heat generating part 160 along with the operation of the ultrasonic oscillator 130, and a part of the foreign substance is melted and discharged as the temperature of the water rises.

Therefore, in the filtration apparatus of the present invention, foreign matter adhered to the filter medium layer 110 is removed by microvibration while direct vibration is applied to the filter medium layer 110, so that the desorption effect is improved, and even with a small number of ultrasonic oscillators 130 It is economically advantageous to transmit the vibration to the wide range of the filter medium layer 110.

According to another embodiment of the present invention, the high-pressure backwash water is supplied through the guide base 120 together with the oscillation of the ultrasonic oscillator 130, and the high-pressure backwash water is supplied to the spray hole 152 formed in the ultrasonic oscillation expansion pin 150 The backwash water is sprayed and the cleaning is performed directly between the layers of the filter media 110.

Therefore, foreign matter adhering to the filter medium layer 110 can be easily removed, and the discharged foreign matters can be easily discharged, thereby improving the backwashing efficiency and improving the filtration efficiency.
