Description

Filtering Apparatus Employing the Rotor for Multistage Generating Variable Vortex Flow}

The present invention relates to an apparatus for filtering a fluid (hereinafter referred to as raw water / source water) containing contaminants such as various impurities or mixtures into a purified fluid (hereinafter referred to as purified water), in particular in a plurality of layers in a closed barrel. The present invention relates to a multi-stage filtration device provided with a vortex generating rotor for each of the provided filtration membranes and configured to have a multi-stage configuration by varying the diameter of each rotor.

In general, a filter (hereinafter referred to as a membrane / membrane) is a very thin porous membrane having a plurality of fine pores formed in a filtration apparatus for filtering raw water containing contaminants or mixtures of various impurities or mixtures with clean purified water. ) Is built-in.

Therefore, when raw water containing various contaminants is introduced into the filtration device, the contaminated raw water passes through the membrane provided in the filtration device and is filtered cleanly, and the purified water is filtered out through the purification water treatment passage and is not filtered out of the membrane. Various impurities or debris can not stick to the surface or pores of the membrane or are concentrated and stagnated inside the filtration device. When the concentration is concentrated above a certain concentration, it is discharged to the concentrated water outlet by a separate signal system.

At this time, the pores of the membrane are blocked by contaminants that are concentrated and adhered to the surface or pores of the membrane, and when a certain time passes, the membrane's filtration / purification capacity is reduced and eventually needs to be replaced. Therefore, the membrane is provided with a means for removing various contaminants adhering to the membrane surface or pores to maintain the membrane's filtration capacity for a long time.

As described above, a device for removing various impurities adhering to the membrane and continuing the filtration capacity has been developed and disclosed. Among them, the invention developed and filed by the present applicant (Application No. 10-2007-0106192, "Sealed Wastewater Treatment System with Ultrasonic Exciting Device") is well known in detail for its filtration process and principles.

This is briefly described as follows.

When contaminated raw water enters, the contaminated raw water is filtered through the pores provided in the membrane and pure water is discharged. The filtered water is discharged along the purified water outlet, and the contaminated raw water passes after a certain time. It is concentrated and discharged to the concentrated water outlet. At this time, the raw water containing contaminants in the membrane is filtered so that the impurity that does not pass through the pores formed in the membrane cannot be received by the rotational force generated by the rotation of the vortex generating rotor installed in the rotational shaft, that is, the vortex force. At the same time, the impurities do not block the pores of the membrane to maintain the filtration capacity.

As shown in FIGS. 8 and 9, the conventional filtering device 50 applying the same principle as described above is provided with a barrel 51 having an external and sealing function, and a plurality of layers inside the barrel 51. Membrane 52 for filtering contaminants and the rotation shaft 54 which is rotated by the driving motor 53 while being alternately provided with the membrane 52 and rotated together with the rotation shaft 54 And a vortex generating rotor 55 for generating a vortex, a raw water inlet 56 through which contaminated raw water mixed with various impurities, etc. flow into the barrel 51, and contaminated raw water is introduced into the membrane 52. Purified water outlet (57) for discharging the clean purified water filtered by the) and the concentrated water outlet (58) for discharging the concentrated water of contaminated raw water remaining in the barrel (51) without passing through the membrane (52) And the like.

The conventional filtering device 50 having the structure as described above rotates the rotary shaft 54 by the drive motor 53 while the raw water containing various contaminants enters the raw water inlet 56 for introducing the raw water. do. Subsequently, the vortex generating rotor 55 rotated by the rotation shaft 54 is stirred to infiltrate the introduced raw water so as to remove or prevent impurities from the raw water stuck to the surface and pores of the membrane 52. Optimize the function of the membrane (52).

And contaminants of raw water are continuously accumulated in the barrel 51 as the raw water is continuously introduced. If the concentration is more than a predetermined concentration, the concentrated water outlet is opened through a separate function, and the concentrated water is discharged to the outside.

The conventional filtration device 50 having the structure as described above is configured to be installed in most of its shape in the direction perpendicular to the ground bar, such a vertical filtration device 50 can not be configured larger than a certain height. there is a problem. This is because the floor height of the installation site may be limited, and when the large-scale installation is impossible, the multi-layer structure may not be installed, and if the filtration device 50 is installed too high, there is a high risk of falling.

And the other problem of the filtration device 50 is installed at a certain height but the diameter of the membrane 52 or the rotor 55 is large when the diameter of the vortex generating rotor 55 is configured to a large capacity or more This results in too much weight of the membrane or rotor. Therefore, due to the weight of the membrane or the rotor, they are bent down or sag, and thus can not exert a filtration function.

In addition, another problem of the filtration device 50 is that the concentrated water discharge port 58 in which the size (diameter) and concentration of the concentrated water of the rotor 55 provided at the raw water inlet portion 56 into which the raw water is introduced is maximized. ) Is the same size (diameter) of the rotor 55 provided in the site. This is because the pollution concentration of the raw water introduced into the raw water inlet 56 is much lower than the concentration when discharged to the concentrated water outlet 58, so the size of the rotary rotor 55 on the raw water inlet side and the raw water outlet side. Since it is not necessary to consume the driving power by providing the same size and drive the same, it is wasting power to operate the driving motor by driving the driving motor uniformly. The reason why the concentration of raw water is increased from the raw water inlet 56 to the concentrated water outlet 58 toward the concentrated water outlet 58, and thus the purified water is filtered out while the raw water is filtered from the membrane 52 provided at the raw water inlet 56. As it goes out, the pollution concentration increases as it goes to the exit side.

Accordingly, the filtration device of the present invention has been devised to solve the various problems as described above, but the conventional filter device having a vertical shape is configured horizontally, that is, a horizontal type, but the filter pack configured by a predetermined size into a single module It can be configured in large capacity by connecting several filter packs according to the purification capacity of raw water, and can respond quickly to the demands of users.The size of the vortex generating rotor according to the pollution degree of raw water makes the rotor It is possible to reduce the driving force to rotate the motor, which can greatly increase the size of the filtration device and its operation efficiency, and to change the shape of the rotor to reduce power, so that the horizontal and vertical vortices can be generated simultaneously. The purpose is to provide a filtration device using a generator.

Filtration device using a multi-stage variable vortex generating rotor of the present invention for achieving the above object is a closed barrel forming a body having a left and right cover means, and a plurality of membranes fixed at regular intervals in the barrel , A rotating shaft installed to rotate at the center axis of the barrel, a plurality of rotating rotors fixedly installed at predetermined intervals on the rotating shaft, a raw water inlet through which raw water is introduced, a purified water outlet through which purified water is discharged from the barrel, and impurities Concentrated water outlet for discharging the solid matter of the raw water contained in the concentrated state, and the shaft support bracket to prevent the rotating shaft from sagging or bending; The sealed barrel is provided horizontally, each membrane and the rotary rotor is provided perpendicular to the ground, the rotary rotor from the left side cover means provided with the raw water inlet to the right side cover means provided with the concentrated water outlet It is provided alternately with the membrane and has a feature to form a multi-stage rotary rotor while gradually increasing its diameter.

This is because the shape of the conventional rotary rotor is installed above and below the membrane, the same size is configured to generate a vertical vortex in a single direction orthogonal to each membrane, by installing a rotary rotor smaller than the diameter of the membrane In addition to the vertical vortex occurring between the membranes installed at the upper and lower parts of the rotating rotor, a horizontal rotor is generated in the outer direction of the rotary rotor (the centrifugal force direction) that is smaller than the membrane, that is, the part larger than the diameter of the rotating rotor. In this case, two types of vortices, vertical and horizontal vortices orthogonal to each other, are generated.

In addition, the hermetic barrel and the multilayer membrane provided therein, the rotating shaft and the vortex generating rotary rotor constitute a filter pack consisting of a single module, and the filter pack is connected and expanded to meet the required purification capacity. It is characterized in that the expansion to the filtration device is possible.

As described above, the filtration device using the multi-stage variable vortex generating rotor according to the present invention has the smallest size (diameter) of the rotary rotor provided at the raw water inlet side through which raw water is introduced, and gradually increases toward the concentrated water outlet where the concentration of contaminants increases. By providing a multi-stage vortex generating rotor that increases the size (diameter) of the rotating rotor, it is effective to minimize the power cost and production cost required to drive the rotating shaft, and to apply the rotor that generates both horizontal vortex and vertical vortex at the same time. By maximizing the eddy current effect, and by using the filter pack consisting of a single module, it is possible to increase the capacity according to the change of the purification capacity of the raw water, so it is easy to convert to a large capacity. The efficiency can be maximized.

Hereinafter, a first embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic perspective view of a filtration apparatus according to the present invention and a state diagram partially showing a configuration of an internal structure, and FIG. 2 is a cross-sectional view of FIG.

Filtration device 10 using a multi-stage variable vortex generating rotor according to the present invention has a left cover means 11 and a right cover means 12, as shown in Figs. 130 and the membrane 14, which is a porous membrane of a plate type for filtering contaminated raw water, which is installed at a predetermined interval inside the barrel 13, and is connected to the closed barrel 13 to form a body. A rotating shaft 16 installed at an inner center of the barrel 13 and connected to a driving shaft of the motor 15, and fixedly mounted to the rotating shaft 16, alternately provided with the membrane 14. And a rotary rotor 17 for generating a vortex, a raw water inlet 18 through which contaminated raw water flows in the left cover means 11, and purified water provided in the right cover means 12. It is provided in the purification | cleaning water discharge port 19 which discharges, and the said right cover means 12. Auxiliary bracket for supporting the barrel (13) and the shaft support bracket 21 and the barrel 13 are installed at regular intervals so as to prevent the rotating shaft (16) from sagging or bent to discharge the concentrated water. 21a).

And the vortex generating rotary rotor 17, as shown in Figure 2, the right cover provided with the concentrated water outlet 20 from the left cover means 11 side provided with the raw water inlet 18 The means 12 are alternately installed between each of the membranes 14, and a multistage rotary rotor is installed so that its size, that is, its diameter, is gradually increased. This means that the raw water at the side of the raw water inlet 18 into which the contaminated raw water is introduced has a low pollution concentration and gradually increases the pollution concentration toward the concentrated water outlet 20 while the raw water passes through the respective membranes 14. As the membrane 14 provided closer to the concentrated water outlet 20 increases, the degree of fixation of impurities increases. Therefore, since the force of the vortex (Vortex) for removing such fixing impurities should be gradually increased to the concentrated water outlet 20 toward the rotary rotor 17, the rotor 17 is gradually larger.

In addition, as shown in <a> of FIG. 4, a plurality of rectangular vortex generating protrusions 22 are formed at a predetermined interval at the end of the most far-direction side of each of the rotary rotors 17. When the rotary rotor 17 is rotated by the projections 22, vortices in the direction of centrifugal force are generated more and more, which causes each of the membranes 14 to be larger in size, i.e., larger than the diameter of the rotary rotor 17. The force of the vortex is transmitted to the impurities of the raw water in the space between them to prevent the pores of the membrane from clogging or to remove the fixing impurities.

More specifically, as shown in FIG. 6, each of the rotary rotors 17 provided between the membrane 14 and the membrane 14 has a size / diameter of the size of each membrane 14. It is installed smaller than the diameter, wherein the rotary rotor 17 is rotated between the respective membranes 14, and in this process the rotary rotor 17 between the upper and lower surfaces of the rotary rotor 17 and the respective membranes ( Vortex is generated by the rotational force of 17. Since the vortices are generated vertically with respect to each of the membranes, they are called vertical vortices (A). Vortex in the direction of centrifugal force is generated between the membranes 14 located at a portion larger than the diameter of 17) and the vortices are generated horizontally with respect to each of the membranes 14 and the rotary rotor 17. This is called horizontal vortex (B).

In addition, the vortex generating protrusions 22 of the rectangular shape formed at the end of the most far direction side of each rotary rotor 17 is deformed into a triangular vortex generating protrusion 22a, as shown in FIG. In this case, the triangular vortex generating protrusions 22a may be installed on the circumferential surface of the rotary rotor 17, but alternately installed so that one of the triangles is one upward and one downward. It can also be configured.

Therefore, the vertical vortex generated on the upper and lower surfaces of the rotary rotor 17 and the horizontal vortex generated on the outer circumferential surface of the rotary rotor 17 are generated between the respective membranes 14 while being orthogonal to each other. It is possible to easily prevent or remove impurities adhering to or stuck to the surface or pores of c) to prevent deterioration of the filtration function.

As shown in FIG. 3, the filtration apparatus 10 using the multi-stage variable vortex generating rotor as described above has an axial support bracket 21, an auxiliary bracket 21 a, a rotation shaft 16, and a rotary rotor 17. By installing a single module consisting of a single filter pack 23 consisting of a membrane 14 and a barrel 13, and installing it in multiple stages, it is possible to construct a filtration device having a necessary capacity according to the filtering capacity of the contaminant. That is, the filtration device 10 is to be expanded by connecting the filter pack 23 in multiple stages.

Here, the sealed barrel 13 constituting the body, the membrane 14, the rotary rotor 17 and the rotating shaft 16 is configured to be horizontal, that is, horizontal to the ground bar, which is the filtration device 10 ) To easily expand to large capacity.

Accordingly, in order to extend and expand the filter pack 23, the filter pack 23 is continuously fastened by the connection fastening means 130 as many times as necessary for the corresponding capacity, thereby using the multistage variable vortex generating rotor. Filtration device 10 can be easily expanded to a large capacity. Here, the connection of each of the rotating shafts 16 provided in the filter pack 23 may be made by inserting the shaft connecting portion in an uneven form or by using other known shaft connecting means.

In addition, Figure 5 shows a cross-sectional view showing a state of another embodiment of the present invention, which is installed in the filter pack 23, the ultrasonic vibration device 24 penetrates through the membrane 14, the ultrasonic vibration device ( 24 is operated while the ultrasonic wave generated in the separate ultrasonic generator 25 is transmitted through the incoming power line 27 installed through the inside of the shaft support bracket 21.

Here, the shaft support bracket 21 is formed in the shape of a steering wheel of the vehicle, which is composed of a circular body portion 210 and a cross-shaped support 220 as shown in FIG.

 Therefore, when raw water containing contaminants enters the raw water inlet 18, the raw water is filled in the barrel 13, and then purified by passing through each membrane 14 provided in the barrel 13. Purified water is discharged to the purified water outlet 19, concentrated raw water is discharged to the concentrated water outlet (20).

At this time, the rotary rotor 17 is rotated by the driving motor 15 so that the pores formed in the membrane 14 are not blocked, and vortices are generated by the rotational force, thereby forming pores formed in the membrane 14. By removing impurities adsorbed, the filtration function of the membrane 14 is prevented from being lowered, thereby increasing the filtration efficiency. At the same time, when the excitation device 24 is operated to further increase the filtration efficiency, the adsorption impurities in the pores that are not removed by the vortex can be further removed, thereby further improving the filtration efficiency.

In addition, the ultrasonic vibration device 24 may be provided at one side of the membrane 14 as in the present embodiment, and may be installed and operated at two or more positions as necessary.
