Description

The present invention relates to a filter for purifying polluted water, and more particularly, to a filter capable of maintaining a high level of filtering effect while reducing a flat area for installation. .

Conventionally, as the filter, an appropriate filter medium, mainly a sand material, is deposited to an appropriate thickness and spread flatly on the bottom of the filtration tank disposed parallel to the ground surface. Filter layer is formed, and the polluted water or polluted water (hereinafter simply referred to as polluted water) to be filtered is injected into the space area above the filter layer in the filter tank, and gravity is used to While the polluted water is allowed to permeate down the inside of the filter layer (or the polluted water may be flowed in the opposite direction), the desired polluting substance contained in the polluted water in the filter layer is the polluted water. Water is removed from the lower end of the filter layer through an appropriate drainage treatment system by separating and removing it from the filter, and the water is distributed appropriately to a section requiring it for reuse. Be served .
In the above-mentioned prior art, the filter medium mainly composed of sand deposited in the filter tank backflows air and filtrate water from below to remove the contaminants when the filters are blocked by the contaminants. Do. Alternatively, it is removed from the layer, washed at a predetermined place and returned to the filter tank, or the filter tank is sequentially or intermittently withdrawn from the layer using an appropriate discharging means. It is usually designed to wash it in place and back into the filter bed.

Such a known filter has a simple mechanism, so that the manufacturing cost is low, and furthermore, since the means for moving the contaminated water and the filter medium can be easily configured, it is widely used as an economical filter. However, in the case of the filter, since the filter is designed to be horizontal, the installation area for installing the filter is increased, and the cost for purchasing the land is increased. However, even if it is intended to improve the capacity of the filter, there is a disadvantage that the installation area of the filter needs to be increased proportionately.
Therefore, the filter using the conventional particulate filter medium such as sand has a filtration surface that is the installation area of the filter, and the installation area needs to be taken wider than other facilities. , The need to reduce the area was increasing.
In order to maintain the filtration efficiency equal to or higher than that of the prior art while solving the problems in the conventional filter, for example, the filter medium in the filter has been accommodated so far. To increase the wall surface of the filter tank to achieve three-dimensionalization, to increase the filtration pressure by placing the filter tank in a pressurizable container, or to make the particle size of the filter medium coarse and reduce the resistance Technical proposals have been made on how to speed up the flow rate of the filtrate.

However, even with the above-mentioned improved technology, the filtration performance is lowered and the quality of the treatment liquid is lowered, etc., and addition of a coagulant etc. is required to maintain the quality, etc. There is a problem that disadvantages such as rising and an increase in the number of steps of waste liquid treatment occur.
For example, Japanese Patent Publication No. 51-34587 (patent document 1) is seen as an example of the method of achieving three-dimensionalization of the said filter machine.
In the filter of Patent Document 1, a rectangular filter chamber 4 filled with filter material 5 is disposed in an upright cylindrical container 1, and the filter chambers 4 are opposed to each other. The rising wall portion is a pair of shutter walls 3 and 6 having water permeability, and the liquid to be filtered that has flowed into the container 1 is made to flow into the filtration chamber 4 through the shutter wall 3, and the liquid to be filtered is Is moved horizontally in the filter medium 5 to perform filtration, and then the filtered liquid is extracted from the filtration chamber 4 through the other shutter wall 6 and discharged to the outside of the container 1 A three-dimensional filter with a system is disclosed.

The filter of Patent Document 1 has an effect that the mechanism is simple and the operation cost is low, and it is evaluated as a technique for solving many of the problems of the above-mentioned prior art. In order to further increase the efficiency of the filter, it is necessary to further increase the height of the filter, or to increase the number of appropriate unit units. It can not be denied that there is a limit of

By making the configuration 35 bent or bent, as described later, it is effective to generate the phenomenon that the vicinity of the central portion is bent downward by the weight of the fluid and the filter medium 30 during use, as described later. There is also an effect that can be prevented.

In addition, in the filter 100 according to the present invention, as shown in FIG. 5, the shelf portion 18 provided in any of the shelf plate-like wall portions 4 to 7 is the shelf. In a situation where the pair of right frame portion 31-2 and left frame portion 31-3 constituting the plate-like wall portions 4 to 7 are attached with an appropriate angle, at least a part of the shelves The plate portion 18 is formed so as to be pivotable through an appropriate mechanism, and the shelf portion 18 is formed at a predetermined time or when a predetermined event occurs, or by an arbitrary operation by the operator. The filter medium is expanded and accumulated in a triangular shape on the upper surface of the shelf plate portion 18 by displacing the shelf plate portion 18 downward by rotating the shelf plate portion 18 downward toward the vertical shape.

As a result, another filter medium discharge for collecting the appropriate dropped filter material 30 on the bottom surface 2 of the internal space area 14 of the filter container 1 and effectively discharging it to the outside of the filter container 1 It is possible to provide transport means.
Of course, in the specific example of the present invention, it is needless to say that all of the shelf plate portions 18 can be configured to be pivotable downward.
Thereby, in the filter 100 of the present invention, when the filtration operation is continued beyond the predetermined time, the filter medium provided at the bottom of the second space area portion 10 The discharge / conveyance operation of the filtration material 30 can be executed more efficiently and in a shorter time in cooperation with the discharge / conveyance means 17 and the other filtration material discharge / conveyance means.

In the filter 100 using the filtration method according to the present invention, in general, it is necessary to temporarily stop the filter 100 itself for the regeneration of the filter material 30 due to the clogging of the filter material 30. Therefore, as one means for extending the life of the filter medium 30, the filter medium 30 with a large particle size is mainly disposed on the upstream side with a large load, and the filter medium 30 with a small particle size is gradually reduced. However, in the present invention, there is no need for the filter, and the filtration is performed by utilizing the shelf plate-like wall portions 4 to 7 having the shelf plate portion 18. It has become possible to reduce the number of stops of the machine 100 and the stop time.
That is, in the filter 100 according to the present invention, the respective shelf plate portions 18 are attached to the respective shelf plate wall portions 4 to 7 in a rotatable state. Things are also desirable examples.

In order to improve the filtration throughput of the filtration apparatus 100 or to compensate for the reduction in the capacity for filter medium replacement, that is, to effectively filter the filtration processing capacity of the filtration apparatus 100. In order to improve the internal space portion of the filtration container portion 1 In addition, it is possible to arrange a plurality of the filtration processing units 19 adjacent to each other in the vertical direction or in the horizontal direction.

FIG. 6A shows that, in the filtration device 100 according to the present invention, three filtration processing units 19 are disposed adjacent to each other in a one-dimensional direction in the inner space portion of the filtration container portion 1. 6B is a plan view of a specific example showing the configuration example, and FIG. 6B is a side sectional view thereof.
Moreover, in the present invention, the filtration processing unit 19 can be arranged two-dimensionally adjacent to the internal space of the filtration container part 1 as shown in FIG. 6 (C). It is a top view which shows the example of a structure which has arrange | positioned the said filtration process unit 19 adjacent to the internal space part of 1 by 3 each by the said vertical direction and a horizontal direction.
In the embodiment shown in FIG. 6 (C), there is a possibility that the filtrate supply passage for the filter processing unit 19 and the outflow passage of the filtered liquid are independently and independently provided. Therefore, it is necessary to introduce partition means for that purpose appropriately.

It is also a preferred embodiment to configure as follows.

In the present invention, by adopting the configuration as described above, the filtration device 100 can significantly increase the filtration area per installed area of the facility so far, and the new installation can be made compact. Instead, by applying the configuration of the present invention to a part of the existing equipment, it is possible to easily increase the filtration processing capacity of the filtration device 100 by three to four times or more.
That is, in the conventional filtration device, the filtration material 30 is simply spread in the filtration container portion 1 and the filtration treatment liquid is allowed to flow and filtered in the vertical direction from the upper surface or the lower surface. In the specific example, as is apparent from FIGS. 6A and 6B, it is possible to utilize the upper surface of the buttocks, that is, the entire upper surface of the filtration processing unit 19 as the filtration processing surface. The filtration device 100 according to the present invention has an effect that the filtration area can be expanded several times as compared with the conventional filtration device having the same plane area.

Furthermore, in the present invention, by adopting the above-mentioned another specific example, the extraction operation of the filter medium 30 becomes relatively easy, so that the clogging of the filter layer can be delayed by the continuous supply. This becomes possible easily, and it becomes possible to reduce the loss due to stopping of the filtration device 100 for the regeneration of the filtration material 30, and to reduce the working efficiency.
On the other hand, to describe the configuration of still another specific example in the present invention, as shown in FIG. 7, the outer shelf plate wall portion 4 and the inner shelf plate wall portion 6 and the outer shelf In the filter medium filling portion 12 formed between the plate-like wall portion 5 and the inner shelf plate-like wall portion 7, further shelf plate-like wall portions 39-1 and 39-2 are provided. A filtering device 100 is provided in parallel to the outer shelf plate-like wall portions 4 and 5 and the inner shelf plate-like wall portions 6 and 7.

More specifically, as shown in FIG. 7, in the specific example of the filtration apparatus 100 according to the present invention which is further different, the filtration container 100 in the filtration apparatus 100 contains the present invention. Similar to the configuration of the filtration device 100, the shelf plate-like wall portions 4 to 7 are arranged in parallel with each other in the manner as shown in FIG. 1, but in particular, the outer shelf plate-like wall portion 4 and Another shelf plate-like wall portion 39-1 having a height substantially equal to the height of the inner shelf plate-like wall portion 6 between the inner shelf plate-like wall portion 6 and the outer shelf plate-like shape Between the wall portion 5 and the inner shelf plate wall portion 7, another shelf plate wall portion 39-2 having a height substantially equal to the height of the inner shelf plate wall portion 7 is disposed. The other shelf plate-shaped wall portions 39-1 and 39-2 are, of course, similarly to the shelf plate-shaped wall portions 4, 5, 6 and 7, they are constructed from the plate-like body. Short , That is, a plurality of shelf plate portions 18 formed in a long shape having a long longitudinal direction, the pair of right frame portions 31 in any of the shelf plate-like wall body portions 4, 5, 6, 7 And 2 is attached to the left frame portion 31-3 in a fixed or pivotable state with an appropriate angle, and is provided on the other shelf plate-shaped wall portion 39-1 The extending direction of the plurality of shelf plates 18 is the same as the extending direction of the plurality of shelf plates 18 provided in the outer shelf plate wall portion 4, and the shelf plate wall portion A configuration in which the spreading direction of the plurality of shelf plates 18 provided in 39-2 is the same as the spreading direction of the plurality of shelf plates 18 provided in the outer shelf plate wall 5 Is the one that is adopted.

In the present invention, by adopting such a configuration, as described later, it is possible to selectively take out only the filter material in the upstream portion which is easily clogged, to regenerate and replenish it, to extract the filter material, to reclaim, While being able to reduce the amount of replenishment, it becomes possible to extend the life of a filter material bed greatly.
Next, other specific embodiments of the filtration apparatus 100 according to the present invention will be described in detail with reference to the drawings.
First, in the filtration device 100 according to the present invention, the shelf plate-like wall portions 4, 5, 6, 7 are filter media always under pressure from the inside, and it is necessary to take measures to prevent deformation. It is.

In particular, when there is strong shaking such as an earthquake, there is a risk that some or all of the shelf plate-like wall portions 4, 5, 6, 7 may collapse or deform, and the repair costs a considerable amount of money. Since there is a risk, the outer shelf plate wall 4 is shown as a dotted line in FIG. 3 in order to prevent collapse or deformation of the shelf plate walls 4 to 7 when the event occurs. A fixing portion 400 formed by using appropriate fixing means for connecting and fixing both of the top portions of the two and the five, and as a specific example thereof, the inner shelf plate-like wall body It is also a desirable embodiment to provide a fixture 410 for connecting and fixing both of them between the apexes of the parts 6 and 7, and further, the outer and inner shelf plate-like wall parts 4 and 6, or It is also possible to provide a similar fixing tool 420 between 7 and 5 and, further, the outer shelf plate-like wall 4 5 and between predetermined wall portion of the filtering vessel portion 1 of the apex portion and the filtration device 100 by providing the coupling fixtures 430 for coupling fixing are possible.

As a further specific example in the present invention, the same technical concept as the configuration for improving the stability and the strength of the filter container part 1 against earthquakes and the like by using the various fixtures 400 to 430 described above 8A, a pair of the shelf plate-like wall portions disposed adjacent to each other, for example, the pair of inner shelf plates One of the contact surfaces of the mutually opposing tip portions (the outer shelf plate-like wall portions 4 and 5 are the container portions 1) of the plurality of shelf plates 18 provided in the wall portions 6 and 7 Bonding and fixing is performed using a suitable bonding tool or connecting member 440 that bonds parts or the whole, and further includes an adhesive.
With such a structure, it is possible to effectively prevent destruction and collapse of the shelf plate-like wall portion, and to reliably contribute to the stability and the strength of the filtration container portion 1.

In the specific example, for the purpose of improving the flowability of the liquid to be treated in the space area 14 and the treatment liquid in the internal space area 15, as shown in FIG. Providing an opening 450 having an appropriate size in at least a part of the shelf plate 18 is also a desirable example.
Furthermore, in another specific example of the filtration device 100 according to the present invention, combining the above-described two types of reinforcement / stabilization construction to obtain a stronger and more stable filtration container part 1 For example, as shown in FIG. 9, the mutually opposing tip portions of the plurality of shelf plates 18 provided in the pair of inner shelf plate walls 6 and 7 are And any two of the shelf plate-like wall portions 4 to 7 may be simultaneously joined and fixed using an appropriate connector or connection member 440 including an adhesive, for example, Select the shelf plate-like wall portions 4 and 5 or the shelf plate-like wall portions 4 and 6, and use appropriate connection fixtures 400 to 410, 430, etc. as shown in FIG. 8A. It is desirable to fix the connection.

Furthermore, in another embodiment of the filtration device 100 according to the present invention, when the length L of the shelf plate portion 18 in the shelf plate-like wall portions 4 to 7 is increased, the filtration can be performed during use. The movement of the material 30 and its weight tend to cause the central part to curve downward and hang down, and the shape of the surface of the ridge formed by the filter material 30 is partially deformed, and the filtration process is performed. There is a risk that parts that are partially degraded with respect to functions may be generated, and it is necessary to increase the thickness or increase the width unnecessarily to increase the strength of the shelf board, the effective filtration area decreases, and the facility cost increases. Are concerned.

In order to ameliorate such problems, in another embodiment of the filtration apparatus 100 according to the present invention, as shown in FIG. 10, each of the desired shelf-like wall sections 4 to 7 is vertically elongated. Between the plurality of closely-arranged shelf plates 18 arranged in parallel with each other in the direction, and an appropriate spacer portion 50 is inserted, and the center of each shelf plate 18 mainly It is intended to effectively prevent the section from falling downward or curving downward.
The material and size of the spacer portion 50 are not particularly limited, and the spacer portion 50 is made of an appropriate metal material or synthetic resin material.
In FIG. 10, a member is used in which the spacer portion 50 has a desired thickness and the shape seen from the side has a bowl-like shape, and this is approximately 1 at the substantially central portion of the respective shelf plate portion 18. Although the example in which only the individual pieces are arranged is disclosed, in the present invention, the number of the spacer parts 50 used and the arrangement place are not specified, and a plurality of the spacer parts 50 are adjacent to each other. It may be disposed in the longitudinal direction of the shelf portion 18 with a desired distance between the pair of the shelf portions 18.

Further, the spacer portion 50 does not have to be a member having a bowl-like shape, and as shown in FIG. 10C, it can be used in any shape such as a rod, plate or hollow square.
Next, still another embodiment of the filtration device 100 in the present invention will be described in detail with reference to FIG.
That is, in each of the specific examples according to the present invention described above, the respective shelf plate portions 18 individually constitute the inner and outer shelf plate wall portions 4 to 7 through appropriate joining means. Although the left and right frame portions 31-2 and 31-3 are attached, in this example, the shelf plate-like wall portions 4 to 7 themselves are easily and inexpensively In order to enable efficient manufacture in a short period of time, a shelf plate portion in which the inner plate wall portions 6 and 7 and the outer shelf plate wall portions 4 and 5 are integrally formed separately. The inner plate-shaped wall portion and the outer shelf-shaped wall portion having the same function as that of the above-described example are configured only by stacking the shelf plate-shaped wall unit portions 60 and 61 having the functions.

That is, as shown in FIG. 11A, when the rectangular frame portion 70 constituting the shelf plate-like wall unit 60 having the shelf portion function is formed, the rectangular frame 70 is used. The corresponding pair of edge portions 53 is formed into an inclined surface such that both edge wall portions form a shape in which both of them are expanded obliquely upward, and the shelf plate portion 18 has a function corresponding thereto. At the same time, the other pair of opposing edge portions 51 is formed on a substantially vertical wall surface, and the bottom surface of the whole is a space portion 52.
The pair of edge portions 53 and the subsequent edge wall portions 54 are portions having a function corresponding to the shelf plate portion 18 and the inclination angle thereof is 0 degrees to 30 degrees with respect to the horizontal plane as described above. Is set to an appropriate angle in the range of.
The constituent material of the frame portion 70 is not particularly limited, and can be manufactured using an appropriate metal material, an appropriate synthetic resin material, or the like.

In the specific example of the present invention, as shown in FIG. 11A, a plurality of the frame portions 70 are stacked in the longitudinal direction so as to obtain a predetermined height, and they are stacked. The outer shelf plate-like wall according to the present invention as shown in FIG. 1 is stably fixed by laminating the frame parts 70 with each other in a stable manner using appropriate joining means 76 or fitting fitting mechanism 75 etc. The parts corresponding to the upper end portions of the body parts 4 and 5 are completed.
In the present invention, as the means for fixing and holding the plurality of frame members 70 stacked in the vertical direction to each other, the above-mentioned joining means 76 or the fitting mechanism 75 or the like is used. In addition to the above, as shown in FIG. 11C, an appropriate number of fitting holes 78 are formed at a part of the upper edge of the frame 70 at the same time as the lower part of the frame 70. An appropriate number of projection members 77 are formed and arranged on a part of the edge, and the appropriate fitting hole 78 provided on a part of the upper edge of the one frame portion 70 is provided. Alternatively, the projection member 77 provided on a part of the lower edge portion of the other frame portion 70 joined to each other may be inserted and fitted. .

On the other hand, the outer shelf plate-like wall portions 4 and 5 and the inner shelf plate-like wall portions 6 and 7 in the middle to lower portions below the upper end in the filtration device in the present invention In order to realize the structure of the portion where the two are mixed by the above-mentioned integral frame structure, the rectangular frame portion 70 which constitutes the shelf plate-like wall unit portion 60 shown in FIG. A shelf plate-like wall unit portion 61 consisting of a frame portion 71 in which the length in the width direction is reduced to about half is separately prepared, and as shown in FIG. 11B, the shelf plate-like wall unit portion 61 This can be realized by vertically overlapping and laminating the lower end portions of the shelf plate-like wall unit portion 60 described above in parallel with each other.

The stacking height and the number of stacked layers of the frame portions 71 in this specific example can be determined as appropriate, and the frame portions 71 of the stacked layers are shown in FIG. Similar to the above, mutual joining can be achieved by using an appropriate joining means 76 or a fitting mechanism 75.
The final completed state of the filter 100 in this example is as shown in FIG. 11 (B), and the upper shelf portion is integrally formed with the outer shelf plate wall portions 4 and 5. In the lower layer portion, the outer shelf plate wall 4 and the inner shelf plate wall 6, and the outer shelf plate wall 5 and the inner shelf plate wall 7 are integrally molded. Since it is configured in the same shape as that described above, the stability and strength characteristics of the filtration container part 1 can be considerably improved.
In the above-described specific example, the shelf portion 18 is pivotably joined to a part of the left and right frame portions 31-2 and 31-3 of the shelf plate-like wall portions 4 to 7. Although an example is shown and shown, in the alternative embodiment according to the invention shown in FIG. 11, it is not possible to adopt such a mechanism.

FIG. 12 is a cross-sectional view showing the configuration of yet another specific example of the filter 100 according to the present invention, and basically, the configuration as shown in FIG. 8 and the shelf plate as shown in FIG. The wall unit portions 60 and 61 are alternately laminated.
The shelf plate-like wall unit as shown in FIG. 11 is more robust than the unit as shown in FIG. 8 in that the edge portion 51 connects the shelf plate portion 18 of the outer inner wall constituting the shelf plate-like wall body However, the amount of materials increases and the cost increases. The cost of the shelf plate wall is a problem compared to a conventional filter with a filter material, and combining it becomes a countermeasure for the problem of cost reduction, and it is impossible with the specific example shown in FIG. The effect of the pivoting of the shelf portion 18 becomes possible.

Next, a method of cleaning the filter medium 30 in the filter device 100 in the present invention will be described.
That is, FIG. 13 (A) is a cross-sectional view showing the configuration of a basic example of the filtration apparatus 100 according to the present invention, and in the filtration apparatus 100 concerned, the related art according to a known method. The filter medium 30 is gradually and continuously or intermittently discharged from the base 2 of the filtration container part 1 using an appropriate discharging means 17 and subjected to an appropriate cleaning / regeneration treatment, and the upper end of the filtration container part 1 The method of reinjecting into the said filtration container part 1 from the part is employ | adopted.

This is because there is a problem that when the filter medium 30 is used continuously for a long period of time, the filtration function of the filter medium 30 is lowered and a good sewage treatment effect can not be exhibited. It is necessary to stop the movement of the filtration device, which negatively affects the efficiency.
However, in the above-described conventional example, in the method of extracting the filter medium 30 from the base portion 2 of the filter container portion 1, foreign substances captured during movement of the filter medium 30 are detached from the filter medium 30 and scattered. There was also the problem of not being the preferred method.
Moreover, since the filter medium moves to the downstream part with little dirt in the upper part of the filter medium 30, there is a problem that the circulation amount of the filter medium is large and it is difficult to exhibit a good sewage treatment effect comparable to the expected fixed bed. I understood.

Furthermore, in such conventional methods, the most heavily soiled filter media are mainly upstream of the filter media 30, while the filter media 30 present downstream of the filter media loading section 12 are mostly soiled. In many cases, the cleaning effect is reduced because the soiled filtration material 30 and the soiling-free filtration material 30 are simultaneously mixed and discharged in the conventional cleaning method of the filtration material 30 as described above. At the same time, it takes a long time to actively discharge the soiled filter material 30, causing a problem of being uneconomical.
In addition, since the filter material 30 present in the downstream part is generally not in a dirty state, it is not necessary to carry out discharge treatment strongly and continuously, for example, in the case of slow filtration, about once a year. It is in a state where it can sufficiently cope with periodic removal and cleaning by batch processing, and in that sense as well, there has been a demand for improvement in the conventional filter material cleaning method described above.

Therefore, the inventor of the present invention gives priority to only the filter medium 30 near the upstream portion in the closed filtration container unit 1 by adopting the configuration according to another aspect of the present invention shown in FIG. Since it is possible to selectively discharge the filter, there is an effect that it is possible to reduce the extraction amount of the filter medium 30, and at the same time the efficiency of the purification process can be improved. Since there is no movement of 30, it is possible to obtain the quality of treated water similar to the above-described embodiment of the present invention.
That is, the outer shelf plate wall 4, the inner shelf plate wall 6, the outer shelf plate wall 5, the inner shelf plate wall 7 and the inner shelf plate wall 7 By providing shelf plate-like walls 39-1 and 39-2 at the same height and in the same direction as the outer shelf plate-like wall body and regulating the flow of the filter medium, the water quality is improved and stabilized, and the expected waste water edge effect It turned out that you can demonstrate

Further, in the present embodiment, since the movement of suspended solids to the lower portion in the filtration container portion 1 is small, the regeneration interval of the filter medium 30 can be further extended than in the above embodiment.
The filter material cleaning method according to the present invention is, as shown in FIG. 13 (B), an inside formed between the outer shelf plate wall 4 and the other shelf wall 39-1. The space portion 320 and the internal space portion 321 formed between the outer shelf plate-like wall portion 5 and the other shelf plate-like wall portion 39-2 are used as a movement passage of the filtration material 30. And the filter material 30 particularly contaminated in the vicinity of the upper portion 11 ′ in the filtration container 1 to be sucked toward the base 2 by the appropriate filter material discharging means 310, the internal space 320 and the filter 321 is configured to be actively pulled out, discharged, and washed via the other, while between the other shelf plate-like wall portion 39-1 and the inner shelf plate-like wall portion 6 And the space area portion 9, 1 formed between the other shelf plate-like wall portion 39-2 and the inner shelf plate-like wall portion 7 The filtering material 30, which is focused on the filtering material filling portion 12 made of will be maintained in hardly moves.
