The present invention relates to a filter system having a continuous real-time filtration and washing function, and more specifically, to a filter system having a continuous real-time filtration and washing function that efficiently filters a large amount of foreign substances contained in raw water, while continuously forcibly washing a filter medium whose pores are blocked by foreign substances during the filtration process and whose filtration function is reduced, thereby continuously securing the function of the filter medium.

In general, water purification plants use various types of filtration systems to remove microorganisms and suspended solids.

As an example of the most recent representative filtration system, Korean Patent Publication No. 10-2024-0012062 (published on January 29, 2024) relates to a continuous cleaning filtration device. Specifically, it is applied to various places where filtration is required to filter foreign substances contained in water while continuously cleaning to improve filtration performance. The technical feature of the present invention is that the filtration filter part is installed inside the housing, a rotating stand is provided on the upper side of the filtration filter part, and a washing part is provided that is connected to the rotating stand and rotates to wash the outer surface of the filtration filter part.

However, these conventional technologies have the problem that the washing part acts as a resistor to the flowing fluid, which reduces the filtration efficiency, and that the washing part needs to be periodically replaced due to deformation, which complicates the process, and above all, that effective washing is difficult.

In addition, although various means and methods for cleaning filter media are presented in many documents, there is still no clear solution that can effectively resolve filter media clogging during continuous operation of the filtration system.

A filter system having a continuous real-time filtration and washing function according to the present invention comprises: a cylindrical housing member having an internal space and a central axis arranged vertically; a filtering means installed in the internal space of the housing member to filter out floating substances; a driving and power transmission means installed on an upper portion of the housing member to generate power and transmit the same; a rotating body coupled to the driving and power transmission means and rotating around the central axis of rotation arranged vertically; and a washing means coupled to the rotating body and rotating to remove floating substances filtered by the filtering means.

The washing means is characterized by being configured to remove floating substances captured in the filtering means by spraying washing water from one side among the inside and outside of the filtering means and sucking floating substances separated by the washing water sprayed from the other side.

Through this, the filtering function of filtering various suspended substances contained in raw water is performed, while at the same time, the suspended substances captured in the filtering means are forcibly washed away through the filtering function, thereby completely resolving the problem of the filtering operation having to be stopped or the filtering function being reduced when the filtering means is washed in the prior art.

Hereinafter, with reference to FIG. 1, the main components of the present invention described above will be described in more detail. First, the housing member is composed of an upper housing (12) arranged on the upper side and having an output pipe (11) formed on one side, a middle housing (14) arranged so that its upper end is in contact with the lower side of the upper housing (12) and having an input pipe (13) formed on the opposite side of the output pipe (11) of the upper housing (12), a lower housing (15) arranged so that its upper end is in contact with the lower side of the middle housing (14), an upper cover (16) formed so as to block the upper side of the upper housing (12) and in which a driving and power transmission means is installed, and a lower cover (17) formed so as to block the lower side of the lower housing (15).

Here, the output pipe (11) and the input pipe (13) are provided with an output pipe flange and an input pipe flange, respectively, for connection with other pipes, and the upper housing (12), the middle housing (14), and the lower housing (15) are mutually connected by flanges, and their dimensions, such as material, diameter, height, and thickness, can be appropriately selected in consideration of the raw water inflow pressure, design flow rate, etc., and a Teflon lip seal (T) and a bearing are installed on the upper cover (16) for connection with a rotating body, specifically, a rotating shaft (31) described below, and for maintaining airtightness.

And the filtering means is formed of a woven mesh filter (23) in the shape of a cylinder, which is fixed at the upper end to a filter tube upper flange (21) formed on the inner surface of the housing member, specifically, on the upper inner surface of the middle housing (14), and fixed at the lower end to a filter tube lower flange (22) that blocks the lower end, and is arranged parallel to the housing member.

Here, the upper flange (21) of the filter tube is fixed by inserting an O-ring between it and the upper flange of the intermediate housing (14) to block a portion of the raw water from flowing into the filtered water side due to the inflow pressure, and is installed at the same height as the upper flange of the intermediate housing (14) to ensure sufficient rigidity compared to being installed in a relatively thinner part. In addition, the lower flange (22) of the filter tube is configured to support the lower part of the mesh filter (23) and prevent its deformation, but is configured to be able to close the lower part of the mesh filter (23), and a through hole is formed in the center so that the rotation shaft assembly (35) described later can pass through this part, and a sealing member such as a lip seal and a bearing is installed on the inner surface of the through hole to maintain sealing with the rotation shaft assembly (35). In addition, the mesh filter (23) is used by processing a filter fabric woven with metal threads into a cylindrical shape or a cylindrical shape with folds by adding reinforcing meshes on both sides to filter suspended solids exceeding the design filtration rate from raw water, and designing it to withstand the collision pressure of high-pressure washing water by using a mesh-shaped fabric with a filtration rate of 1 to 40 ㎛ as the center and a reinforcing material with 30 to 60 meshes.

Through this, the microfiltration membrane, which is installed upstream of the ultrafiltration membrane or nanofiltration membrane in water treatment and plays an important pretreatment role to reduce their load, can be replaced while stably processing a large design flow rate, and the filter is designed and configured to manage the differential pressure, which is the difference between the inlet pressure and the outlet pressure, to within 0.3 bar so that the pressure of the filtered water can be directly used at the downstream by increasing the flow rate of the filtered water, i.e. the flux.

And as shown in Fig. 1, the lower flange (22) of the filter tube is configured to have a bend in the middle so that the cross-section is stepped along the radial direction, thereby reinforcing the rigidity of the mesh filter (23) against buckling, etc.

And the rotating body is composed of a rotating shaft (31) that is vertically arranged on the upper part of the housing member as shown in FIGS. 1 and 2 and has an upper end coupled to a driving and power transmission means, a high-pressure chamber (32) that is a hollow shaft-shaped hollow shaft having an upper end coupled to the lower end of the rotating shaft (31) and a space formed inside, an inner chamber (33) and an outer chamber (34) that have an upper end coupled to the lower end of the high-pressure chamber (32) and have internal spaces separated from each other, a rotating shaft assembly (35) that has a height of the inner chamber (33) formed higher than that of the outer chamber (34) and that is formed to penetrate the filter tube lower flange (22), and a rotating shaft connector (36) that is formed as an 'L'-shaped tube that is coupled to the upper end of the outer chamber (34) of the rotating shaft assembly (35) and communicates with the internal space of the outer chamber (34).

Here, the high-pressure chamber (32) receives and stores high-pressure washing water generated by the high-pressure pump described later and performs the role of uniformly supplying it to the high-pressure washing slit unit (51) described later, and the rotary shaft connector (36) performs the role of supplying washing water containing floating substances captured by the floating substances capture unit (52) described later into the outer chamber (34) of the rotary shaft assembly (35).

In addition, the present invention further comprises a lower inner flange (41) that is fixedly installed on the lower inner surface of a housing member, specifically, a lower housing (15), and a rotational shaft support assembly (42) that is positioned and joined at the center of the lower inner flange (41) and has an inner surface formed to surround a lower portion of a rotational shaft assembly (35) to support a rotating body from the bottom.

Here, the lower inner flange (41) is a component that divides the inner space of the lower housing (15) into upper and lower parts and allows the rotation shaft support assembly (42) to be fixedly installed. The rotation shaft support assembly (42) supports the rotating body so that it can rotate stably. A Teflon lip seal (T) is installed between the rotation shaft assembly (35) and the rotation shaft support assembly (42) to support the stable rotation of the rotating body and maintain airtightness.

And the washing means is formed by a high-pressure washing slit unit (51) having an inner end coupled to a high-pressure chamber (32) as shown in FIGS. 1 and 2 and protruding toward the outer mesh filter (23), a hollow portion formed inside that is connected to the inner hollow portion of the high-pressure chamber (32), and a nozzle portion formed at the outer end that can spray washing water, and a floating material capturing unit (52) having a lower end coupled to the upper end of a rotary shaft connector (36) and positioned at an angle facing the high-pressure washing slit unit (51) on the outer side of the mesh filter (23) to capture floating materials separated by washing water sprayed from the high-pressure washing slit unit (51) and supply the collected floating materials to the rotary shaft connector (36).

Here, as shown in FIG. 3, the high-pressure washing slit unit (51) is installed so that its end is in close contact with the upper and lower longitudinal direction of the mesh filter (23), and is configured to spray high-pressure washing water through a narrow slit-shaped nozzle at the end, and as shown in FIG. 4, the number of the unit can be configured in multiples depending on the amount of raw water and the load of floating substances, and the speed of the end is determined by the speed of the rotating body, and the speed of the rotating body is determined and controlled by the inflow pressure of the raw water, the collision pressure of the high-pressure washing water, the filtration rate of the filter, etc., and the floating substance collection unit (52) is provided with a floating substance suction port capable of sucking floating substances in the direction or surface of the mesh filter (23) along the entire length in the upper and lower directions, and rotates while facing the high-pressure washing slit unit (51) on the same radius line with the mesh filter (23) so that the floating substances are immediately captured as they are detached from the mesh filter (23) by the high-pressure washing water sprayed from the high-pressure washing slit unit (51).

In addition, the present invention further comprises a hollow tube-shaped high-pressure washing water supplier (61) that is connected to the rotation shaft support assembly (42) through a flange portion and penetrates the inner space of the inner chamber (33) of the rotation shaft support assembly (42) and the rotation shaft assembly (35) to be connected to the inner space of the high-pressure chamber (32), a Teflon lip seal jig (62) that is installed on the lower inner surface of the high-pressure chamber (32) to ensure smooth rotation of the high-pressure chamber (32) and to maintain airtightness between the outer surface of the high-pressure washing water supplier (61) and the inner surface of the high-pressure chamber (32), and a high-pressure washing water supply pipe (63) that penetrates the housing member, is connected to the lower surface of the high-pressure washing water supplier (61), and is connected to a high-pressure pump for forming high-pressure washing water.

Here, the high-pressure washing water supplier (61) is coupled to the rotation shaft support assembly (42) to serve as the rotation center axis of the high-pressure chamber (32) and the Teflon lip seal jig (62), and at the same time, supplies the high-pressure washing water supplied through the high-pressure washing water supply pipe (63) on the lower side of the lower internal flange (41) to the high-pressure chamber (32).

In addition, the present invention further comprises a communication hole (71) formed to communicate the inside and the outside of the inner chamber (33) of the rotary shaft assembly (35) on the upper side of the lower flange of the filter tube, a first communication passage (72) and a second communication passage (73) formed on the flange portion of the rotary shaft support assembly (42) and the high-pressure washing water supplier (61) respectively to connect the inside of the inner chamber (33) of the rotary shaft assembly (35) and the inside of the housing on the lower side of the lower inner flange (41), and a high-pressure pump supply pipe (74) formed on the housing member on the lower side of the lower inner flange (41) to supply filtered water to a high-pressure pump for forming high-pressure washing water.

Through this, a portion of the filtered water passing through the mesh filter (23) flows into the inner chamber (33) of the rotary shaft assembly (35) through the communication hole (71), then flows into the lower housing (15) below the lower inner flange (41) through the first communication passage (72) and the second communication passage (73), and the filtered water thus introduced is supplied to the high-pressure pump through the high-pressure pump supply pipe (74) and used as washing water.

In addition, the present invention further includes a communication passage (81) formed by penetrating the inner and outer sides of the outer chamber (34) of the rotary shaft assembly (35), a communication groove (82) formed as a space on the inner surface of the rotary shaft support assembly (42) to be connected to the communication passage (81), and a floating material discharge pipe (83) connected to the communication groove (82) by penetrating the housing member.

Through this, the floating material that is introduced from the floating material collection unit (52) and supplied through the rotary shaft connector (36) is introduced into the outer chamber (34) of the rotary shaft assembly (35) through the communication path (81) and is delivered to the floating material discharge pipe (83) through the communication groove (82) and discharged.

And the driving and power transmission means is composed of a rotary shaft driving motor (91) and a reduction gear assembly (92) coupled with the rotary shaft driving motor (91), and the torque and rotational speed of the rotary shaft driving motor (91) and the torque and rotational speed of the high-pressure pump are controlled by a PLC and inverter-based controller. At this time, the PLC and inverter-based controller detects and controls the amount of raw water inflow, the amount of filtered water discharge, etc.

The processing process in the filter system having the continuous real-time filtration and washing function according to the present invention described above is specifically described with reference to FIG. 5.

First, to explain the filtration process, raw water flows into the internal space of the housing member through the input pipe (13) of the middle housing (14), and the raw water that flows in passes through the cylindrical mesh filter (23) from the outside to the inside, and is converted into filtered water with floating substances removed, and is discharged through the output pipe (11) of the upper housing (12), thereby performing a filtration operation (here, raw water corresponds to the black arrow, and filtered water corresponds to the blue arrow).

Next, regarding the formation and supply process of the washing water, a portion of the filtered water existing inside the mesh filter (23) through the mesh filter (23) flows into the inner chamber (33) of the rotating shaft assembly (35) through the communication hole (71) formed in the inner chamber (33) of the rotating shaft assembly (35), and the filtered water that flows in again flows into the inner space of the lower housing (15) below the lower inner flange (41) through the first communication passage (72) formed in the rotating shaft support assembly (42) and the second communication passage (73) of the high-pressure washing water supplier (61), and the filtered water that flows in like this is supplied to the high-pressure pump through the high-pressure pump supply pipe (74), converted into high-pressure washing water, and then supplied to the high-pressure washing water supplier (61) through the high-pressure washing water supply pipe (63), and then passes through the inner space of the high-pressure chamber (32) and is supplied to the high-pressure washing slit unit (51) and sprayed onto the mesh filter (23) through a slit-shaped nozzle. (Here, the high pressure washer corresponds to the green arrow).

Next, with regard to the process of capturing and discharging floating substances, the high-pressure washing water sprayed from the high-pressure washing slit unit (51) separates floating substances attached to the mesh filter (23) and moves them radially outward, thereby causing them to flow into the floating substance capturing unit (52), and the floating substances thus introduced are introduced into the inner space of the outer chamber (34) of the rotating shaft assembly (35) through the rotating shaft connector (36), and then are discharged to the outside of the housing member through the communication passage (81) of the outer chamber (34) of the rotating shaft assembly (35) and the communication groove (82) of the rotating shaft support assembly (42) through the floating substance discharge pipe (83) (here, the flow of the captured floating substances corresponds to the red arrow).

In the present invention, the filtration process, washing water formation and supply process, and floating matter capture and discharge process described above are performed simultaneously as shown in Fig. 5, thereby enabling continuous and stable water treatment work.

Through the above-described configuration, the filter system having a continuous real-time filtration and washing function according to the present invention continuously performs a filtration function for filtering various floating substances contained in raw water, while simultaneously performing real-time washing and immediately discharging the collected floating substances to the outside, thereby completely solving the problem of interruption of the filtration function due to washing and discharge after washing, so that filtration treatment can be continuously performed, and through the optimal design, smooth supply and treatment of raw water is possible, so that stable filtration treatment efficiency is maintained, while the excellent washing function ensures sufficient washing effect, and sufficient structural rigidity is secured so that a large amount of raw water can be processed, while through the optimal arrangement, there is an advantage in terms of production and maintenance, etc.
