Description

Filter unit having sealing function for filter module in disc unit

The present invention relates to a filtration device having a filter module airtight function of the disk unit, and more particularly, to a soluble material, a colloidal material or a floating material according to the properties of the treated water such as sewage, purified water, sewage, waste water and process water. Filtration device with full or semi-sediment rotating disk filter designed to remove SS) at the same time, without fixing the filter module having the structure fixed to the filter frame on both sides of the segment of the disk unit. Both sides of the filter module are tightly fixed to both sides of the segment of the disc unit to prevent the mixing of the sewage and the treated water in a manner that ensures perfect airtightness of the contact portion, and also prevents the suction unit from being damaged. Also makes it easier to remove and attach filter modules onto segments of a disk unit. When manufacturing the filter module, it is possible to fix the filter on the filter frame more easily, thereby reducing the labor cost of the filtration device itself, and greatly improving the quality and reliability including the productivity of the product. But it was invented to significantly reduce the cost of the maintenance of the filtration device.

A micro-disc filter device (namely, a filtration device), which is generally named as an element (filter) that has become a disk, is a device for filtering foreign matter contained in the wastewater by being installed in a water flow path.

In the case of such a disk-type filtration device, the direction of the flow of raw water must be different depending on the shape of the filter medium used as the filter. When the filter medium is used as a mesh fiber (woven fabric), the drum through which the raw water passing through the water channel or the water tank is rotated. To be discharged through various drains formed in the wall of the drum, and the raw water discharged through the drains passes through the mesh fiber (woven) filter of the element installed to be supported by the segments on both sides of each drain. While foreign matter contained in raw water is filtered on the inner surface of the mesh fiber (woven fabric) filter, only the treated water is discharged through the mesh fiber (woven fabric) filter.

Here, since the filter medium is a mesh fiber (woven fabric), foreign matters are filtered on the inner surface thereof, and the washing medium is easily sprayed with a high pressure from the outside of the mesh fiber (woven fabric) filter to the inside during washing. There is no problem with this because it is cleaned.

In the filtration method of such a disk unit, the coagulation filtration method in which foreign substances in raw water are aggregated by a chemical (coagulant) and filtered to block fine pores of the mesh fiber (woven fabric) filter as the chemical (coagulant) is introduced. Since there is a problem that the cleaning effect is extremely reduced.

On the other hand, when the media unit is used as a villi-type filter in the disk unit, unlike a fiber (woven) filter having a mesh shape, the villi-type filter weaves the villi diagonally by twisting a thread having a predetermined length on one surface of the base plate at an acute angle. As a result, for smooth filtering, raw water introduced into the tank is included in the raw water passing through the chorionic filter of the filter modules installed to be supported by the segment of several disk units which are installed at predetermined intervals on the outer circumferential surface of the rotating drum. After the various foreign substances filtered and purified by the villi-type filter, only the treated water passes through the villi-type filter and is introduced into the rotary drum through several drain holes drilled in the rotary drum and then discharged to the outside.

At this time, the villi-type filter is provided with villi made by twisting several strands of thread as described above, so that the filtration efficiency of various foreign substances contained in raw water is good, and there is no damage such as tearing, unless the villi is bald, and thus the life is long. It has a long and cheap manufacturing cost.

When the raw water passes through the villi-type filter having such a configuration, most foreign substances including relatively large foreign substances in the raw water adhere to the surface of the villi and the micro voids of the base plate among the foreign substances that have passed through the villi. Larger foreign matter is again caught between the micropores of the fabric.

On the other hand, the filter module 30 used in some conventional filtration apparatus is injection molded through a synthetic resin material so as to have an approximately fan-shaped shape and the center thereof is opened as shown in FIGS. 1 and 2, or the iron plate is cut through a press. The villi-shaped filter 33 is fixedly installed on one side of the filter frame 32 formed by using a fastener 38 such as a screw, and a support bracket formed on the segment 31 at the periphery of the filter frame 32. The rubber packing 37 which is in close contact with the 34 and the cover 35 and the like is kept intact.

In addition, a separate filter module is caught on both sides and the bottom of one of the components of the disc unit 3 so that both sides and the bottom of the filter module 30 are fitted as shown in FIGS. 2 and 3, respectively. The loop 312 is integrally or detachably formed to protrude so that the filter module insertion grooves 311 are formed on both sides and the bottom of the filter module 30, and a cover 35 is formed on the upper surface of the segment 31. It is a structure that can be detachably coupled by a bolt or the like.

However, the filter module 30 having such a configuration uses the several fasteners 38, such as screws, to fix the villi filter 33 on one side of the filter frame 32. As a result of adopting a method of fixing the periphery of each one at regular intervals, the assembly work of the villi filter is very complicated, and the production cost of the product is increased, and the villi filter installed on each filter frame 32 is provided. Since the tension of (33) does not have the same state, there is a problem that the quality and reliability of the product itself are degraded.

In addition, the rubber packing 37 installed to maintain the airtightness at the contact surface between the filter module insertion groove 311 and the cover 35 of the segment 31 is aging or hardened due to the characteristics of the material when used for a long time, so that the airtightness is lowered. Of course, some of them may be torn or cracked, and due to long-term use of the filter module itself, a disk having a semi-sedimentary state for intermittently cleaning various foreign matters attached to the micro voids of the fabric fabric, including the outer circumferential surface of the filter module When washing by spraying a high-pressure washing water toward the villi from the outside of the villi-type filter having a state that does not settle in the water of the unit, the washing water containing various foreign substances and the filter module insertion groove 311 and the cover of the segment 31 Inflow into the disc unit 3 (leakage), such as a crack formed in the rubber packing 37, including a gap formed between the contact surface with the 35). ), The purified water may be contaminated by washing water and foreign matters, and thus, a number of filter modules need to be replaced, resulting in high maintenance costs for the filtration device.

In addition, when manufacturing the segments 31, the filter module insertion grooves 311 must be formed on the left, right, and bottom surfaces of the both sides except for the upper surface, so that the manufacturing cost of the segment is high, as well as the filter module 30 on both sides of the segment 31. ) When installing or separating from the filter module 30, as shown in Figure 2, the filter module insertion grooves 311 in a predetermined direction to be pushed or pulled out well, so that the removal and attachment of the filter module is very difficult. But there is a problem that a lot of labor costs.

In addition, media such as mesh fibers (woven filters) or villi filters have the property of easily deforming with pressure from the outside, for example, when the jet of washing water is strongly sprayed to clean these media, As the filter medium is pushed or swung, the filter frame 32 of the filter module 30 is provided with a lattice support 321.

By the way, when the lattice itself is formed sparsely when the lattice supporter 321 is installed in the filter frame 32, a part of the villi filter 33 is interposed between the bars of the supporter 321 when the high-pressure washing water is irradiated. There is a problem that the foreign matter that is buried in the milia villi into the space portion formed in the intensive concentration in the recessed portion does not flow smoothly.

However, when the bar of the support 321 is densely formed, there is a problem that the support itself interferes with the flow of the wash water including the raw water.

In addition, in the filtration apparatus having a disk filter (see Korean Patent Publication No. 10-0876198), as shown in Fig. 4, foreign substances contaminated by the filter 33 at the submerged portion by the filtration process are attracted by the suction force of the suction unit 5. The foreign matter contaminated by the filter 33 of the non-immersion portion of the filtration apparatus is configured to be washed by the high-pressure jet washing machine 4 for spraying the washing water at a high pressure.

However, in the filtration device having a disk filter having such a configuration, as described above, the filter module insertion groove 311, which can be hooked on both sides and the bottom of the filter module 30, respectively, is provided with a bar shape The filter module hook ring 312 of the protruding and the upper surface of the segment 31 has a configuration that can be detachably coupled to the cover 35 by a bolt or the like, the filter contaminated while rotating the rotating drum When the suction was washed using the suction unit, a lot of problems such as abrasion or damage caused by hitting the filter module hook ring that the suction port side of the suction unit made of metal in contact with the filter rotates.

On the other hand, the present applicant is a solution for solving the above problems, the filter module of the filter unit of the Korea Patent Publication No. 10-0916323 filtration unit, the attachment device and the filter fixing device of the domestic Patent Publication No. 10-0916320 filter It was presented as.

Among them, Korean Patent Publication No. 10-0916323 "Filter module detachment, attachment device of the disk unit for filtration device", as shown in Figure 5 to 8, the rotating drum installed to cross the interior of the raw water tank (1) On the outer circumferential surface of (2), several filter modules 30 composed of filter frame 32 and filter 33 and several disk units 3 composed of segments 31 are provided at regular intervals. In the filtering device having a configuration in which a jet washer 4 having a plurality of high pressure jet nozzles is installed between the disc units 3, the filter module 30 is disposed in the transverse direction at the bottom of both segments 31. The bottom portion of the support bracket (34) is inserted into the hanging by force, and the upper cover of the segment 31 and the upper surface of the two filter modules 30, the cover 35 is detachably installed, the cover 35 is Longitudinal section has a "┏┓" shape, transverse direction The outer shape has a shape that is bent to correspond to the upper outer circumferential surface shape of the segment 31.

In addition, the upper and lower portions of the filter module 30 are formed between the upper both sides of the segment 31 and both wings of the cover 35 and the segments 31 by the elastic volume change of the filter 33 itself. The filter module 30 is sealed between the bottom both sides and the inner surface of the support bracket 34 and is detachably installed on both sides of the several segments 31 while being fixed to the filter frame 32. An extension part 334 is formed at the periphery of the filter 33 to cover a portion of the rear part of the filter frame 32, and the extension part 334 of the filter 33 bent to the rear surface of the filter frame 32. It is characterized by providing elastically the several tensioning fixture 36 which has elasticity in between.

At this time, the tension holder 36 is provided with hooks 362 at both ends of the tension springs 361 so as to be able to hook several hook holes 335 drilled in the extension part 334 of the filter 33. And the upper, lower, left, right middle portions of the filter 33 extension portion 334, which are bent to the rear surface of the filter frame 32, and the upper and lower edges thereof are disposed to cross each other. .

In addition, when the extension part 334 of the filter 33 is folded to the back side of the filter frame 32, the step is prevented from being stepped between the extension parts 334 due to mutual overlap at the corners of the filter frame 32. The cutout 336 is formed by cutting a part of the extension part 334 overlapping at the corners of the rear surface of the filter frame 32, and the extension part 334 positioned at both sides of the cutout part 336. Each hook hole 335 is drilled around the contact portion of the hook, and one hook 362 provided at both ends of the tension spring 361 of the tension holder 36 is drilled in the two extension parts 334. It is characterized in that the contact portion of the extension portion 334 adjacent to each other by being caught at the same time by the hole 335 to maintain the state coupled to each other by the hook 362.

The filter frame 32 of the filter module 30 is integrally injection-molded with a grid-shaped filter supporter 321 having a constant size square through hole 323, but has a constant size square through hole ( The horizontal / vertical bar 322 integrally formed so that the step 323 is formed and the step is not generated at the intersection point is injection-molded so that the longitudinal cross section has an annular shape, and the back of the filter 33 and the support 321 The horizontal / vertical bars 322 are intended to have line contact with each other.

That is, in the filter module detachment and attachment apparatus of the disk unit for a conventional filtration apparatus, as described above, the filter module 30 including the filter frame 32 and the filter 33 in the segments 31 of the disk unit 3 is described. In the case in which the bottom surface of the segment 31 is forcibly pressed into the bottom of the segment 31 without forming an insertion groove or the like for fixing the filter module 30 to both the bottom and both sides of the segment 31 when both sides are to be installed. Segment 31 is installed in such a way that a support bracket 34 that can be hooked and installed on the upper side of the segment 31 is simultaneously wrapped around two upper surfaces of two filter modules 30 installed on both sides of the segment 31. The form which detachably attached the cover 35 for fixing to the upper part is shown.

However, in such a configuration, both sides of the segment 31 of the disc unit 3 and both sides of the filter module 30 are not fixed to each other by means of separate fixing means, and the support bracket 34 is simply installed only at the bottom of the unit segment 31. Thus, the bottom of the filter module 30 is pushed in and the upper part of the filter module 30 has a cover 35 having a “종단” shape in the state in which the upper portion of the filter module 30 is in close contact with the segment 31. The upper surface portion itself is simultaneously wrapped to form the upper part of the segment 31 and then the cover 35 is fixed to the segment 31 by using a fastener such as a screw. 31) The airtightness of both sides and the two-sided contact portion of the filter module 30 are not maintained, and the upper part of the filter module is bent when the upper portion of the segment is fixed by forcibly pressing the upper part of the filter module through the cover. If the contaminated filter is suction-washed using a suction unit (not shown), especially when rotating the rotating drum, both sides of the filter module may be Since the airtight to the contact parts thereof is broken away from both sides of the segment, the space is formed at both sides of the segment of the disc unit and the both sides contact of the filter module, so that the contaminated washing water including various foreign substances flows into the purified water through these spaces. Leakage) to contaminate the purified water.

Accordingly, in some cases, as shown in FIG. 9, the middle parts of both sides of the filter module 30 are fixed to the middle parts of both sides of the segment 31 of the disc unit 3 by using the bolts 71 and the nuts 72. In this case, when the contaminated filter is sucked and cleaned by using the suction unit while rotating the rotating drum, the bolt head which secures the middle part of both sides of the filter module to the segment has a protruding shape. Not only does the suction port side of the suction unit hit the head of the bolt to wear or damage, but also segments of the disk unit fixed to the rotating drum are installed at narrow intervals, so that both sides of the segments Install the filter modules individually and fix both sides of the filter modules to both sides of the segment using bolts and nuts in a narrow space. There is also a problem that is very difficult to dismantle the fixed state.

The present invention has been made in order to solve such a conventional problem, and when manufacturing a disk unit for use in a filtration device having a rotating disk filter, the support bracket which is forcibly caught by the bottom of the filter module in the transverse direction from the bottom of several segments And a cover is detachably installed on the upper part of the segment and the upper surface of the two filter modules, as well as a male and female locking means formed on both inner surfaces of the segment and on both sides of the filter frame of the filter module. When fitting the bottom of the filter module to the bracket, both sides of the filter module are also fixed to both sides of the segment by the male and female locking means, so that both sides of the filter module can be connected to both sides of the segment of the disc unit without any additional fixing work. Tight contact This makes it possible to completely prevent mixing of sewage and treated water, as well as preventing the suction unit from being damaged, and also allows the filter modules to be easily detached and attached to the segment of the disc unit. When manufacturing the filter module, it is possible to fix the filter on the filter frame more easily, which can reduce labor cost according to the fabrication of the filtration device itself, and greatly improve the quality and reliability including the productivity of the product, as well as maintain the filtration device. It is an object of the present invention to provide a filtration device having a filter module airtight function of the disk unit, which can greatly reduce the cost of the present invention.

Another object of the present invention is to protrude several spacers on the back of the support of the filter frame so that the two filter frames detachably installed on both sides of the segment of the disc unit to maintain a constant interval irrespective of externally applied pressure. When the rotating disk filter itself is in the complete or semi-settled state, the center part of the filter frame is pushed into the segment of the disk unit by the hydraulic pressure of the treated water, so that the filter unit of the disk unit can be prevented in advance due to the deterioration of filtration performance. It is to provide a filtration device having a module airtight function.

The present invention for achieving the above object is composed of several filter modules consisting of a filter frame and a filter, a segment having a support bracket at the bottom, and a cover for fixing two filter module upper surfaces at the top of the segment.

Since the elastic locking ring 62 is caught by any one of the vertical wings 611 of both vertical wings 611 of the locking pieces 61 protruded to the inner surface center of both pillars 311 of the segment 31 as shown in FIG. When the cover 35 is fixed to the upper portion of the segment 31 by using bolts or the like, the filter module 30 itself is fixed to both sides of the segment 31. 31 are respectively fixed to the double-sided pillars 311.

Of course, when the filter module 30 is to be separated from the segments 31, the cover 35 is separated from the upper surface of the segment 31 and the filter modules 30 installed on both sides of the segment are adjacent to each other. In the narrow space formed between the units (3), it can be easily separated by an undirected pulling operation.

Therefore, the operation of installing each filter module 30 on the segment 31 of the disk unit 3 or separating it from them is not only very simple, but also the structure of the segment 31 is simple and the number of components is small. The production cost and labor costs according to the production of the unit 3 itself can be greatly reduced, and in particular, both sides of the filter module 30 may be divided into two-sided pillars 311 of the segment 31 of the disc unit 3 without additional fixing. Since the airtightness of the contact portion is perfectly secured to the contact part, it is possible not only to completely prevent mixing of sewage and treated water, but also to prevent the suction unit 5 from being damaged by the female and female locking means 6. It is.

On the other hand, in the present invention, the inclined locking surface 612 is further formed on the inside of the vertical wing 611 of the locking piece 61 inclined in the direction from the top toward the lower portion, the elastic locking ring 62 In addition, the filter module 30 is formed on both sides of the segment 31 by further forming an inclined locking surface 622 which is inclined wider toward the inner side from the bottom to the upper portion as opposed to the inclined locking surface 612. When coupled to the filter module 30 is moved to the rotating drum 2 side along both sides of the segment 31 of the disc unit 3, the inclined locking of the elastic locking ring 62 protruding from the filter module 30 The surface 622 is moved on the inclined locking surface 612 of the locking piece 61 formed on both pillars 311 of the segment 31, and the filter module 30 itself gradually shifts to correspond to the moving distance. The inner side of the As the 30 is pushed further into the support bracket 34 side of the segment 31, the coupling force of the male and female locking means 6 is increased, so that both sides of the filter module 30 are connected to the segment 31 of the disc unit 3. It is more closely fixed to the double-sided pillar 311 is to further increase the airtight force for the contact portion.

Therefore, the filter module 30 and the segment are irrespective of the external suction pressure when filtering various wastewater using the filtration device to which the present invention is applied or cleaning the contaminated filter 33 using the suction unit 5. Since the airtightness of the contact portion between the 31 is maintained as it is, it is possible to completely prevent mixing of sewage and treated water through the space generated in these contacts, as well as the male and female catching means 6 itself is the filter module 30 Since it does not have a state exposed to the outside of the suction unit 5 can be prevented in advance to damage the suction unit (5).

In addition, in the present invention, by further protruding the guide pieces 325 inside the bottom sides of both sides of the filter module 32 of the filter module 30, the filter module 30 is mounted on the segment 31. Since the guide piece 325 of the filter frame 32 is first slid and pushed along both inner surfaces of the segment 31 while being caught by the inner surfaces of both pillars of the segment 31, the filter module 30 itself. Can be prevented from being incorrectly mounted on the segment 31.

In addition, in the present invention, the inclined guide piece between the upper surface of the vertical wing 611 of the engaging piece 61 protruded to the inner surface of both pillars 311 of the segment 31 and the inner surface of both pillars 311 of the segment 31. By further protruding the 63, when the coupling of the filter modules 30 to the segment 31, erroneous mounting is prevented primarily by the guide pieces 325 as described above, and then the filter module. The outer side of the elastic engaging ring 62 of the 30 is moved along the inclined guide piece 63 of the segment 31 and secondly to allow the filter module 30 to be balanced itself, even though the segment is in a narrow space. Even when the filter modules 30 are assembled on the 31, the inclined guide piece 63 formed on the segment 31 balances the filter module 30 with the shape of the segment 31. Even a skilled person can ensure that the filter module 30 is The segments 31 are able to be combined.

On the other hand, the upper and lower portions of the filter module 30 has a form that is forcibly sandwiched between the bottom surface of the segment 31 and the support bracket 34 and between the upper both sides of the segment 31 and the inner surface of the cover 35. In addition, since both sides have a state of being fixed to both pillars 311 of the segment 31 by the male and female locking means 6 as described above, even if no separate rubber packing or the like is installed, the filter 33 ) Between the bottom of the segment 31 and the support bracket 34 and between both sides of the segment 31 and the inner surface of the cover 35 by its elastic volume change (ie, the volume change in which the villi are elastically pressed). Is automatically sealed.

In particular, when the villi-type filter is installed as the filter 33, since the elastic volume change of the villi woven to the filter is larger than that of the woven fiber filter having a mesh shape, the bottom surface and the support bracket of the segment 31 ( The sealing effect between 34 and between the two sides of the segment 31 and the inner surface of the cover 35 is better.

As such, it is possible to maintain a sealing function between the outer circumferential surface of the segment 31 and the inner surface of the cover 35 for a long time without installing a separate packing means in the filter module 30.

In addition, in the filter module 30 to which the present invention is applied, the filter 33 itself is fixed to the filter frame 32 by using several stretchable fixtures 36 having elasticity.

That is, the extension part 334 is formed by forming the extension part 334 at the periphery of the filter 33 of the filter module 30 which is detachably installed on both surfaces of several segments 31 in a state in which the filter frame 32 is fixedly installed. An extension portion 334 facing each other among the extension portions 334 of the filter 33 bent to the rear surface of the filter frame 32 so that the 334 may be installed to cover a part of the rear portion of the filter frame 32. Several elastic fasteners 36 having elasticity were installed between them.

In this case, the tension fixture 36 is composed of a tension spring (361) having a hook 362 at each end, and the extension spring (361) at a predetermined interval on the extension portion 334 of the filter 33. The hook ring 362 provided at the both ends of the head) has a configuration in which several locking holes 335 can be fitted.

When fixing the filter 33 to the filter frame 32 of the filter module 30 by using the tension-type fixture 36 having such a configuration, the filter 33 bent to the back of the filter frame 32 The tension-type fixtures 36 are installed across each other between corners of the upper, lower, left, and right middle parts of the extension part 334 facing each other diagonally opposite to each other in the upper and lower parts. The elastic force generated in each of the tension fixing fixtures 36 on the main surface is to act evenly on the filter 33 as a whole.

That is, the tension spring 361 of the tension type fixture 36, the center of the upper and lower extensions of the filter 33 extended portion 334 of the filter 33 is bent to the back of the filter frame 32 and the left and right In the middle of the right extension and the upper and lower edges of the upper and lower edges in the diagonal direction facing each other act the same as each other, so that the total tension of the filter 33 exposed to one side of the filter frame 32 is always constant Will be maintained.

In addition, several tension springs 361 are applied to the filter when the washing water injection pressure generated when spraying the washing water for cleaning the filter 33 is performed using an injection nozzle or the like not shown in the outer surface of the filter 33. At the back of the frame 32 to generate a tension force to elastically pull between the extension of the filter 33 and at the same time to buffer the impact force, so to fix the filter directly to the filter frame using a fixture such as a screw Compared with giving, it is possible to continuously produce products with the same elastic force, as well as to significantly improve the quality of the product itself.

At this time, the tension between the upper, lower, left, right middle portion of the filter 33 extending portion 334 facing each other on the rear surface of the filter frame 32 and the corners of the positions diagonally opposite to each other in the upper, lower portion The lengths are different when the type fasteners 9 are installed across each other. In order to make the elastic force generated in each of the tension type fasteners 36 act evenly on the entire filter 33, This can be solved by having a difference in elasticity for each tension spring by changing the length or thickness of the tension spring 361.

In addition, in the filter frame 32 of the filter module 30 to which the present invention is applied, a lattice-shaped filter supporter 321 having a predetermined size through-hole 323 is injection molded integrally, wherein the support The horizontal / vertical bar 322 of 321 is integrally injection-molded with the filter frame 32 so that the cross section has an annular shape, and thus, a step is not generated at the intersection of the horizontal / vertical bar 322 and the support ( The horizontal / vertical bars 322 of 321 are in line contact with each other at the rear surface of the filter 33.

As such, when the horizontal / vertical bars 322 of the supporter 321 come in line contact with the base plate of the filter 33, the micropores formed in the base plate are at least less blocked, thereby increasing the passage of raw water and washing water to the maximum. In addition, the washing water and the foreign matter passing through the fine pores of the base plate during the cleaning flows smoothly into the disk unit 3 along the circumferential surface of the horizontal / vertical bar 322 without hitting the horizontal / vertical bar 322. Since it is possible to go to the back of the filter 33 can greatly improve the cleaning efficiency.

In addition, in the present invention, by integrally injection molding the support 321 itself including the filter frame 32, the weight of the filter module 30 itself may be greatly reduced, thereby driving a rotating drum (not shown). Since the power can be reduced, not only can the production cost of the filtering device itself be greatly reduced, but also the quality and reliability including the productivity of the filtering device itself can be greatly improved, and the cost of maintenance can be greatly reduced.

On the other hand, in the above-described filter unit 32 in the state in which only the grid-shaped filter support 321 having a predetermined size square through-hole 323 is integrally injection-molded in the filter frame 32, the disk unit ( When the filter module 30 is installed and used in each of the segments 31 of 3), the filter support 321 is pushed inward by the pressure applied when the sewage passes through the filter 33, and thus the filter ( The filtration performance of 33) may be lowered.

Therefore, in the present invention, several interval retaining rods 324 having a predetermined diameter and length at predetermined intervals are formed on the rear surface of the grid-shaped filter support 321 integrally formed in the filter frame 32 of the filter module 30. ) By integrally further protruding to form the filter module 30 on both sides of each segment 31 of the disc unit 3, as shown in FIGS. 13 and 14, the filter support of the filter frame 32. (321) Since the free ends of the spacing retaining rods 324 protruding from the rear surface remain in contact with the ends of the spacing retaining rods 324 which are installed on opposite sides of the segment 31, respectively, and eventually rotate. When the disk filter itself is in the complete or semi-settled state, the central part of the filter frame 32 is completely prevented from being pushed into the segment 31 of the disk unit 3 by the water pressure of the treated water (that is, one Seg The bit 31 two filter module 30 itself is provided on the whole maintain the same interval) is in good condition the filtration performance of the filter maeyu.
