Description

TECHNICAL FIELD The present invention relates to a filter for purifying contaminated water, and more particularly to a filter capable of maintaining a high filtering effect while reducing a plane area for installation. .

Conventionally, as the filter, an appropriate filter material, mainly, sand material is deposited to an appropriate thickness on a bottom portion in a filter tank arranged in parallel with the ground surface, and is appropriately laid by laying flat. Is formed, and contaminated water or contaminated water to be filtered (hereinafter simply referred to as contaminated water) is injected into a space region on the filtration layer in the filtration tank, and the gravity is applied to the space. While the contaminated water is allowed to permeate down the inside of the filtration layer (or the contaminated water may flow in the opposite direction), desired contaminants contained in the contaminated water are removed by the filtration layer. By separating and removing water from the filter, the purified water is extracted from the filter through the appropriate wastewater treatment system from the lower end of the filter layer, and is appropriately distributed to the departments that require it for reuse. Provided .
In the above-mentioned known technique, when the filter medium mainly composed of the sand deposited in the filter tank is clogged with the pollutant, the air or filtered water flows backward from below to remove the pollutant. I do. Alternatively, after taking out from the layer and washing it at a predetermined place and returning it to the filtration tank, or using an appropriate discharging means from the filtration tank, continuously or intermittently, sequentially withdrawing from the layer, It is usually designed to wash it in place and return it to the filter layer.

By the way, such a known filter has a simple mechanism, so that the production cost is low, and furthermore, the contaminated water and the means for moving the filter material can be easily configured, so that it is widely used as an economical filter. However, since the filter is designed so that the filter tank is horizontal, the installation area for installing the filter is large, and the cost for purchasing land is high. However, there is a drawback that even if an attempt is made to improve the capacity of the filter, the installation area of the filter must be increased in proportion thereto.
Therefore, in the case of the conventional filter using a particulate filter medium such as sand, the filtration surface is an installation area of the filter, and the installation area needs to be large for other equipment. Therefore, the need to reduce the area has increased.
In order to solve the problems in the conventional filter and to maintain the filtration efficiency equal to or higher than that of the conventional technology, for example, the filter material in the filter has been stored. A method of increasing the wall surface of the filtration tank to achieve a three-dimensional structure, a method of increasing the filtration pressure by placing the filtration tank in a pressurizable container, or a method of reducing the resistance by increasing the particle size of the filter medium Accordingly, technical proposals such as a method of increasing the flow rate of the filtrate have been made.

However, even with the above-described improved technology, the filtration performance is reduced, the quality of the processing solution is reduced, and the like, and the addition of a flocculant or the like is necessary for maintaining the quality. There is a problem that demerits such as an increase and an increase in the number of waste liquid treatment steps occur.
Here, as an example of a method for making the filter three-dimensional, Japanese Patent Publication No. 51-34587 (Patent Document 1) can be found, for example.
In the filter of Patent Literature 1, a rectangular filtration chamber 4 filled with a filtering material 5 is arranged in an upright cylindrical container 1, and the filtration chambers 4 face each other. The upright 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 flows into the filtration chamber 4 through the shutter wall 3, and the liquid to be filtered is Is moved horizontally in the filtering material 5 to perform a filtering process, and then the filtered liquid is withdrawn from the filtering chamber 4 through the other shutter wall 6 and discharged to the outside of the container 1. A three-dimensional filter having a system is disclosed.

The filter disclosed in Patent Document 1 has an effect that the mechanism is simple and the operation cost is low, and is evaluated as a technique for solving many of the problems of the conventional technique described above. In order to further improve 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 is undeniable that there are some limits.

In the filter 100 using the filtration method according to the present invention, generally, it is necessary to temporarily stop the filter 100 itself for regeneration of the filter 30 due to the blockage of the filter 30. Therefore, as one means for extending the life of the filter medium 30, the filter medium 30 having a large particle diameter is mainly disposed on the upstream side with a large load, and the filter medium 30 having a small particle diameter is gradually increased. However, in the present invention, there is no necessity, and by utilizing the shelf plate-like wall portions 4 to 7 having the shelf plate portion 18, the filtration can be performed. It is possible to realize a reduction in the number of times the machine 100 is stopped and a reduction in the time during which the machine 100 is stopped.

Although the details of the configuration of the filtration device 100 having the configuration in which the filtration unit 19 is arranged have been described, in the present invention, the filtration unit 19 is However, in order to improve the filtration amount of the filtration device 100 or to compensate for a decrease in the capacity for replacing the filter medium, that is, to effectively increase the filtration treatment capacity of the filtration device 100 To improve the internal space of the filtration container 1 In addition, it is possible to arrange a plurality of the filtration units 19 adjacent to each other vertically or horizontally.

FIG. 6A shows three filtering units 19 arranged one-dimensionally adjacent to each other in the internal space of the filtering container unit 1 in the filtering apparatus 100 according to the present invention. FIG. 6B is a side cross-sectional view of a specific example showing the configuration example described above.
Further, in the present invention, it is possible to arrange the filtration processing unit 19 two-dimensionally adjacent to the internal space of the filtration container unit 1, and FIG. 6C shows the filtration container unit. FIG. 4 is a plan view showing a configuration example in which three filtration processing units 19 are arranged adjacent to each other in a vertical direction and a horizontal direction in one internal space.
In the above specific example shown in FIG. 6 (C), the supply path of the liquid to be filtered and the outflow path of the filtered liquid for the respective filtration processing units 19 are individually and independently secured. Therefore, it is necessary to appropriately introduce partition means for that purpose.
In the present invention including the specific examples described above, the number of the filtration processing units 19 arranged in the internal space of the excess container unit 1 is not particularly limited, and the filtration required for the filtration device 100 is not limited. It can be determined as appropriate to suit the processing capacity.

It is a specific example that it is desirable that the shelf-like wall portions 4 to 7 are arranged so as to coincide with the arrangement direction of the shelf-like wall portions 4 to 7 individually provided in the other filtration processing units 19. is there.

Further, in the above specific example of the present invention, a plurality of the filtration units 19 disposed in the internal space of the excess container portion 1 are adjacent to each other and between the mutually facing side surfaces. It is also a desirable embodiment to provide the inflow passages 38 for the liquid to be filtered formed at appropriate intervals.
That is, in another specific example of the present invention, the pair of first outer shelf plate-like wall portions 4 and the second outer shelf plate-like wall portion 5 and the pair of first inner shelf plate members 5 are provided. Filter unit unit composed of a wall-like wall portion 6, a second inner shelf-like wall portion 7, and a closing plate 8 that closes between upper ends of the pair of inner shelf-like wall portions 6 and 7. 19 are arranged in a single filter container 1 at a desired interval so that the longitudinal axes of the shelf-shaped wall portions 4 to 7 are parallel to each other. It is also a preferable specific example that the configuration is made as follows.

In the present invention, by employing the above-described configuration of the filtration device 100, it is possible to greatly increase the filtration area per equipment installation area so far, and it is not only possible to make the newly installed equipment 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 capacity of the filtration device 100 three to four times or more.
That is, in the conventional filtration apparatus, the filtration medium 30 is simply spread in the filtration container portion 1 and the liquid to be filtered is passed vertically from the upper surface or the lower surface to perform filtration. In the specific example, as is clear from FIGS. 6A and 6B, the ridge, that is, the entire upper surface of the filtration unit 19 can be used as the filtration surface. In the filtering device 100 according to the present invention, compared with a conventional filtering device having the same plane area, the effect of being able to enlarge the filtration processing area several times is obtained.

Furthermore, in the present invention, by adopting the above-mentioned another specific example, the operation of extracting the filter medium 30 is relatively simple, and thus the continuous supply can delay the blockage of the filter layer. It becomes possible easily, and it becomes possible to reduce the loss due to the stoppage of the filter device 100 for regenerating the filter medium 30 and reduce the work efficiency.
On the other hand, to describe a configuration of still another specific example of the present invention, as shown in FIG. 7, the outer shelf plate-like wall portion 4, the inner shelf plate-like wall portion 6, and the outer shelf plate-like wall portion 6, In the filter material filling portion 12 formed between the plate-like wall portion 5 and the inner shelf-plate-like wall portion 7, further shelf-like wall portions 39-1 and 39-2 are further provided. The filtering device 100 is provided in parallel with the outer shelf wall portions 4 and 5 and the inner shelf wall portions 6 and 7.

More specifically, in another specific example of the filtration device 100 of the present invention, as shown in FIG. Similar to the configuration of the filtration device 100, the shelf-shaped wall portions 4 to 7 are arranged in parallel with each other in a manner as shown in FIG. 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 is provided between the outer shelf plate-like wall portion 6 and the inner shelf plate-like wall portion 6. Another shelf-shaped wall portion 39-2 having a height substantially equal to the height of the inner shelf-shaped wall portion 7 is arranged between the wall portion 5 and the inner shelf-shaped wall portion 7. The other shelf plate-like wall portions 39-1 and 39-2 are, of course, configured from the plate-like body like the shelf plate-like wall portions 4, 5, 6, and 7. Short A plurality of shelf portions 18 formed in a long shape, that is, a long shape having a long longitudinal direction is formed by the pair of right frame portions 31 in any of the shelf-like wall portions 4, 5, 6, and 7. -2 and the left frame portion 31-3 are fixedly or rotatably mounted at an appropriate angle and provided on the other shelf plate-like wall portion 39-1. The extension direction of the plurality of shelf board portions 18 is the same as the extension direction of the plurality of shelf board portions 18 provided on the outer shelf board wall portion 4, and the shelf board wall portion A configuration in which the extension direction of the plurality of shelf portions 18 provided in 39-2 is the same as the extension direction of the plurality of shelf portions 18 provided in the outer shelf-like wall portion 5. Is adopted.

In the present invention, by adopting such a configuration, as described later, it is possible to selectively remove only the upstream filter material that is likely to be clogged, regenerate, and replenish. The amount of replenishment can be reduced, and the life of the filter medium layer can be greatly extended.
Next, another specific embodiment of the filtration device 100 according to the present invention will be described in detail with reference to the drawings.
First, in the filter device 100 according to the present invention, the shelf-plate-like wall portions 4, 5, 6, and 7 are always subjected to pressure from the inside with a filter medium, and a measure for preventing deformation is required. It is.

In particular, when there is a strong shaking such as an earthquake, there is a risk that some or all of the shelf plate-like wall portions 4, 5, 6, and 7 may collapse or deform, and a considerable cost is required for repairing them. Because of the danger, when the event occurs, in order to prevent the shelves 4 to 7 from collapsing or deforming, as shown by the dotted line in FIG. And a fixing portion 400 formed by using an appropriate fixing means for connecting and fixing the both between the apexes of the inner shelf plate 5 and the inner shelf plate-like wall. It is also a desirable example to provide a fixing tool 410 for connecting and fixing both parts between the apexes of the parts 6 and 7, and furthermore, the outer and inner shelf board-like wall parts 4 and 6, or It is also possible to provide a similar fixing member 420 between 7 and 5, and furthermore, the outer shelf-like wall portion 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 of the present invention, the same technical concept as that of the configuration for improving the stability and the strength of the filtration container unit 1 against an earthquake or the like using the above-mentioned various fixing tools 400 to 430 is used. 8A, which is characterized by a pair of shelf plate-like wall portions arranged close to each other, for example, the pair of inner shelf plates as shown in FIG. Of the plurality of shelves 18 provided on the wall-like wall portions 6 and 7 are opposed to each other (the outer shelf-like wall portions 4 and 5 are container portions 1). A part or the whole is joined, and an appropriate joining tool or a connecting member 440 containing an adhesive is used to join and fix.
With such a structure, destruction and collapse of the shelf plate-like wall portion can be effectively prevented, and it is possible to reliably contribute to securing stability and strength of the filter container portion 1.

Further, in this specific example, as shown in FIG. 8B, the liquids to be processed in the space area 14 and the processing liquid in the internal space area 15 are joined together as shown in FIG. It is also a desirable specific example that an opening 450 having an appropriate size is provided in at least a part of the shelf 18 thus formed.
Further, in another specific example of the filtration device 100 according to the present invention, a stronger and more stable filtration container portion 1 is obtained by combining the above-described two types of configurations for reinforcement and stabilization. For example, as shown in FIG. 9, the mutually opposing distal ends of a plurality of the shelf portions 18 provided on the pair of inner shelf-shaped wall portions 6 and 7 are connected to each other. Attach and fix using an appropriate bonding tool or connecting member 440 containing an adhesive, and at the same time, any two of the shelf-shaped wall portions 4 to 7, for example, The shelf plate-like wall portions 4 and 5 or the shelf plate-like wall portions 4 and 6 are selected, and appropriate connection fixtures 400 to 410, 430 and the like are used as shown in FIG. It is desirable to fix the connection connection.

Further, in another specific example of the filtration device 100 according to the present invention, if the length L of the shelf 18 of the shelf-shaped wall portions 4 to 7 is increased, the filtration L during use is reduced. Due to the movement of the material 30 and its weight, the central portion thereof tends 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 filtering process is performed. There is a danger that some parts will be reduced in function, and it is necessary to increase the thickness or increase the width unnecessarily in order to increase the strength of the shelf board, reducing the effective filtration area and increasing equipment costs. Is concerned.

In order to improve such a problem, in another specific example of the filter device 100 according to the present invention, as illustrated in FIG. A suitable spacer portion 50 is inserted between a plurality of adjacently arranged shelf portions 18 arranged in the same direction and in parallel with each other. The portion is effectively prevented from lowering or curving downward.
The material and size of the spacer section 50 are not particularly limited, and are 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 when viewed from the side is a wedge shape. Although an example in which only the spacer portions 50 are arranged is disclosed, in the present invention, the number of used spacer portions 50 and the arrangement location are not specified, and a plurality of the spacer portions 50 are adjacent to each other. The shelves 18 may be arranged in the longitudinal direction with a desired interval between the pair of shelves 18.

Further, the spacer portion 50 does not need to be a member having a wedge-shaped shape, and may be any shape such as a bar, a plate, or a hollow square member as shown in FIG.
Next, still another specific example of the filtration device 100 according to 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 portions 18 individually constitute the inner and outer shelf plate-like wall portions 4 to 7 via appropriate joining means. Although they are attached to the left and right frame portions 31-2 and 31-3, in this specific example, the shelf-like wall portions 4 to 7 themselves can be easily and inexpensively formed. In order to enable efficient production in a short period of time, the inner plate-like wall portions 6 and 7 and the outer shelf plate-like wall portions 4 and 5 are individually molded integrally with each other. Only by stacking the shelf plate-like wall unit units 60 and 61 having functions, an inner plate-like wall unit and an outer shelf plate-like wall unit having the same function as in the above specific example are constituted.

That is, as shown in FIG. 11 (A), when the rectangular frame portion 70 constituting the shelf plate-shaped wall unit unit 60 having the shelf portion function is created, the rectangular frame portion 70 A pair of corresponding edge portions 53 is formed as an inclined surface such that both edge wall portions form a shape that is splayed upward diagonally, and has a function corresponding to the shelf 18. At the same time, another pair of opposing edges 51 is formed on a substantially vertical wall surface, and the entire bottom surface is a space portion 52.
The pair of edge portions 53 and the following edge wall portion 54 are portions having a function corresponding to the shelf plate portion 18, and the inclination angle thereof is 0 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 70 is not particularly limited, and can be manufactured using an appropriate metal material or an appropriate synthetic resin material.

In the specific example of the present invention, as shown in FIG. 11A, a plurality of the frame portions 70 are vertically stacked and set so as to obtain a predetermined height, and are stacked. The outer shelf plate-like wall according to the present invention shown in FIG. 1 is stably fixed by laminating the frame portions 70 to each other using appropriate joining means 76 or a fitting mechanism 75 or the like. A portion corresponding to the upper end portions of the body portions 4 and 5 is completed.
In the present invention, as the means for fixing and holding the plurality of frame portions 70 laminated in the vertical direction to each other, the above-described joining means 76 or fitting mechanism 75 is used. In addition, as shown in FIG. 11C, an appropriate number of fitting holes 78 are formed and formed in a part of the upper edge of the frame 70, and Appropriate number of appropriate protrusion members 77 are formed and formed on a part of the edge portion, and the appropriate fitting hole portion 78 provided on a part of the upper edge portion of the one frame body portion 70 is formed. Alternatively, a structure may be used in which the projecting member 77 provided on a part of the lower edge of the other frame body 70 to be joined to each other is 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 filter device according to the present invention in the middle to lower portions below the upper end portion. In order to realize the structure of the portion where と and 混 在 are mixed with the above-described integral frame structure, the rectangular frame portion 70 constituting the shelf plate-like wall unit portion 60 shown in FIG. A shelf plate-shaped wall unit 61 composed of a frame 71 whose length in the width direction is reduced to about half is separately prepared, and as shown in FIG. 11B, the shelf plate-shaped wall unit 61 is formed. Can be realized by vertically overlapping and laminating the lower end of the shelf plate-shaped wall unit 60 in a state of being parallel to each other.

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

FIG. 12 is a cross-sectional view showing the configuration of still another specific example of the filter 100 according to the present invention, and is basically a configuration as shown in FIG. 8 and a shelf plate as shown in FIG. The wall unit units 60 and 61 are alternately laminated.
The shelf-wall unit shown in FIG. 11 is more robust than the unit shown in FIG. 8 because the edge 51 connects the shelf 18 of the outer and inner walls constituting the shelf-wall. However, the amount of material increases and the cost increases. The cost of the shelf plate-shaped wall is a problem compared to a conventional filter only laid with a filter medium, and the combination can be a measure for the problem of cost reduction, and at the same time, it is impossible with the specific example shown in FIG. The effect of turning the shelf 18 can be achieved.

Next, a method of cleaning the filter medium 30 in the filter device 100 according to the present invention will be described.
That is, FIG. 13A is a cross-sectional view showing a configuration of a basic specific example of the filtration device 100 according to the present invention. The filter medium 30 is gradually or continuously discharged intermittently from the base portion 2 of the filter container unit 1 by using a suitable discharge unit 17, and is subjected to appropriate washing / regeneration treatment, thereby obtaining an upper end of the filter container unit 1. A method of re-injecting the liquid into the filtration container unit 1 from the unit is adopted.

This is because, when the filter medium 30 is continuously used for a long period of time, there is a problem that the filtering function of the filter medium 30 is deteriorated and a good sewage treatment effect cannot be exhibited. It was necessary to stop the operation of the filtration device, which had a negative effect on efficiency.
However, in the above-described conventional example, in the method of extracting the filter medium 30 from the base 2 of the filter container section 1, the foreign matter trapped during the movement of the filter medium 30 comes off the filter medium 30 and scatters. Therefore, there is a problem that the method is not preferable.
In addition, since the filter medium moves to the lower part of the filter medium 30 to the lower part of the dirt, the circulation amount of the filter medium is large, and there is a problem that it is difficult to exhibit a good sewage treatment effect comparable to the expected fixed layer. Do you get it.

Furthermore, in such a conventional method, the filter medium most heavily soiled is mainly the upstream part of the filter medium 30, while the filter medium 30 existing downstream of the filter medium filling part 12 is almost dirty. In many cases, the dirty filter medium 30 and the clean filter medium 30 are simultaneously discharged together in the above-described method for cleaning the filter medium 30, so that the cleaning effect is reduced. At the same time, it takes a long time to actively discharge the soiled filter medium 30, and there is a problem that it is not economical.
In addition, since the filter medium 30 present in the downstream portion is almost in a dirty state, it is not necessary to continuously perform the discharge treatment forcibly. For example, in the case of slow filtration, it is about once a year. It is in a state where it can sufficiently cope with the case where it is taken out and washed periodically by batch processing. In this sense, the above-mentioned conventional method for washing a filtering material has been required to be improved.

Therefore, the inventor of the present application adopts the configuration according to another embodiment of the present invention shown in FIG. 7, so that only the filter medium 30 near the upstream portion in the closed filter container unit 1 has priority. Since the filter medium 30 can be selectively discharged, there is an effect that the amount of extraction of the filter medium 30 can be reduced, and the efficiency of the purification process can be improved. Since there is no movement of 30, it is possible to obtain the same quality of treated water as in the specific example of the present invention described above.
That is, the inner shelf-shaped wall portion 4, the inner shelf-shaped wall portion 6, the outer shelf-shaped wall portion 5, and the inner shelf-shaped wall portion 7 are provided between the inner shelf-shaped wall portions. By providing shelf plate-like walls 39-1 and 39-2 at the same height and in the same direction as the outer shelf-like wall portion to regulate the flow of the filter medium, the water quality is improved and stabilized, and the expected sewage butt effect It turned out that we can demonstrate.

Further, in this specific example, since the movement of the turbid substance to the lower part in the filtration container section 1 is small, the regeneration interval of the filter medium 30 can be further extended as compared with the specific example.
As shown in FIG. 13 (B), the filter material cleaning method of the present invention employs an inner shelf formed between the outer shelf-like wall 4 and the other shelf-like 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 another shelf plate-like wall portion 39-2 are used as a movement passage of the filter medium 30. Then, the particularly contaminated filter medium 30 in the vicinity of the upper step portion 11 ′ in the filter container section 1, which is sucked toward the base section 2 by the appropriate filter medium discharge means 310, is removed from the internal space section 320 and 321 is positively pulled out, discharged, and washed, while the space between the other shelf plate-like wall portion 39-1 and the inner shelf plate-like wall portion 6 is provided. And the space region portions 9 and 1 formed between the another 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.
