Utility Model Implementation

The described device for accommodating a filter cartridge inside a sewer well can be implemented in various embodiments.

As follows from the drawings shown in FIG. 1-5, the device for accommodating the filter cartridge 5 inside the sewer well 2, according to a utility model, is made in the form of a composite support ring 1, containing at least two segments 10, fastened together with the formation of the complete support ring with closed outer and internal contours. As materials from which segments of the support ring can be made, depending on the operating conditions of the well and its design, both traditionally used steel, including stainless steel or cast iron, and polymeric materials, for example, polyethylene, polypropylene, can be used. polyvinyl chloride, vinyl plastic, as well as composite materials, for example, based on fiberglass, or other building materials, for example, reinforced concrete. The segments 10 of the support ring 1 are placed inside the sewer well 2 with the possibility of their fastening to the inner surface of the wall 3 of the well (Fig. 1), which is the side surface of the well, or, located in the upper part of the well, the slab 4 (Fig. 3). The segments 10 are attached to the body casing elements, wall 3 or floor slab 4, by means of clamps 9, which can be used as anchor joints, for example, chemical or mechanical anchor joints.

Moreover, for fastening the segment to the wall of the well, each segment 10 of the support ring is provided with at least one mounting element 7, containing at least one mounting hole 8. The mounting element 7 is located on the outer side surface of the segment, with a large radius rounding in the direction perpendicular to the plane of the base of the ring and, accordingly, of the segment. Moreover, the mounting elements 7 can be made in the form of a flange bent up or down containing mounting holes 8 for installing transverse clamps, or in the form of bent or rigidly fastened, for example, by welding, with an adjacent base, eyes or plates with a mounting hole 8 (Fig. 4, 5). Mounting elements and their corresponding mounting holes are made in such a way as to provide the possibility of lateral arrangement of clamps in them, for their fixing in the wall of the well.

As follows from FIG. 3 of the drawing, in the case of fastening the segments of the support ring to the floor slab 4 of the well, the clamps 9 are placed in the mounting holes 8 made directly in the segments, with the possibility of lateral arrangement of the clamps in them. In particular, it is possible to make mounting holes with a secret arrangement of latches.

The possibility of mounting a device for placing a filter cartridge, in the form of a composite support ring, inside a constructed sewer well equipped with a standard hatch is realized due to the fact that the segments 10 of the described device are moved into the inner volume of the well through the neck of the hatch, without dismantling the hull structures of the sewer well, where they are assembled into a single support ring 1, which, after fixing the segments, its components, to the wall or slab of the well 2 is additionally covered with protective m layer of sealing material on the radial 11 gaps between the segments of the ring and the annular 12 gap between the ring and the wall of the well, as well as the slab, if the segments are attached to it.

The filter cartridge 5 is placed in the hole of the support ring 1 fixed in the well 2. The filter cartridge 5 is attached to the support ring 1 by means of the support flange 6, which is a structural element of the filter cartridge. In order to provide waterproofing, the fastening of the filter cartridge to the support ring is preferably leakproof, for example, by using a protective layer of sealing material along the interface between the filter cartridge and the segments of the support ring and the support flange with segments.

Stormy contaminated wastewater enters the well through the pipeline to the upper part of the filter cartridge, passes through it where it is cleaned, and leaves the lower part of the filter cartridge to the bottom of the well, from where it is drained through the pipe to exit the treated drain.

As follows from FIG. 4 and 5 of the embodiment of the utility model, the fastening of the segments 10 of the support ring 1 to each other can be accomplished by fastening along one of the end elements of the segment, in its lower part, a support plate 13 located horizontally along the plane of the lower base of the segment, with a protrusion behind the limits of the end segment of the segment and the overlap of the junction of adjacent segments, so that the end element of the adjacent segment rests on the upper plane of the base plate 13. At the same time, the position clamps of the segments (on Góry not shown) are mounted coaxially disposed in the through holes 15 and 14 in the base plate and rests on its segment, respectively, fixing position of the segments relative to each other and thereby forming a backup ring assembly with closed inner and outer contours. To simplify alignment coaxially

located through holes in the segment and the plate, as well as the ability to adjust the position of the segments relative to each other, at least one of these holes can be elongated, for example, horizontally elongated oval. Oval (horizontally elongated) openings in the device for accommodating the filter cartridge, in addition, contribute to the possibility of mounting / dismounting the filter cartridge inside the already constructed sewer well through the neck of a standard hatch, without dismantling the elements of the well (hatch, base plate, etc.) because they allow segments to be shifted support rings relative to each other and relative to the elements of the well, thereby simplifying their installation and replacement of the filter cartridge.

In Fig. 5, as an example of such a hole, its placement on the support plate (hole 15, Fig. 5) is selected, however, it is obvious that it is possible to make holes of an elongated shape and on the segment, as well as on both mating elements. However, from the point of view of ensuring reliable fixation of the segments relative to each other, the most preferable embodiment is elongated only one of the coaxial through holes for installing the position fixers of the segments. It should be noted that according to the claimed solution of the utility model, it is most preferable to perform coaxial, through holes of the support plate and segment with an offset to the outer edge of the segment, which allows to simplify the assembly of the support ring at the place of its installation and to provide conditions for a comfortable standard installation of the filter cartridge in the support ring.

As follows from FIG. 4 drawings, support plates, in the case of dividing the support ring into two segments, are rigidly fixed at one end of each of the adjacent segments, which provides a more uniform distribution of the load on the support ring during its operation and simplifies the process of their production. However, it is possible to rigidly fix the plates on the end elements of one of the segments and place the latches on the other. The choice of mounting the base plates to the segments is determined by the configuration of the segments, technological capabilities in production, and the operating conditions of the support ring in the sewer well.

In addition, according to the claimed utility model, the plates 13 are made in such a way that the width and dimensions lie within the overall dimensions and configuration of adjacent segments of the support ring. Failure to comply with this requirement will make it difficult or preclude the possibility of mounting the support ring inside the well and installing a filter cartridge in it.

As already indicated above, in FIG. 4 and 5 show one of the options for fastening segments to each other. It is obvious that in the framework of the claimed utility model, other embodiments of fastening adjacent segments are possible. In particular, the segments and the support plate can be connected to each other by clamps installed in through coaxial holes located at both ends of the plate and on the adjacent end elements of the segments, so that their standard installation provides a tightening of the segments together with the formation of the assembly of the support ring with closed external and internal circuits. The plates can be installed both on the lower and on the upper base, in compliance with the requirement of ensuring standard installation in the support ring of the filter cartridge.

It is also possible to make end elements of adjacent segments with mirrored and counter-directed shelves of equal length, made at right angles, the total thickness of which, when overlapping, is equal to the thickness of the support ring. In another embodiment of the utility model, the end elements of adjacent segments can be made inclined and counter-directed, with a mirror arrangement of the inclined parts, so that their total thickness when overlapping is also equal to the thickness of the support ring. The aforementioned embodiments of the segments of the support ring make it possible to form a support ring with a continuous surface of the bases, which facilitates both the process of mounting the structure in the well and its sealing. The fastening of these end elements, made either in the form of shelves or inclined, can be carried out using clamps located in coaxial, through holes made in adjacent end elements of the segments, bolts or fixing pins can be used as clamps, as well as any other fasteners known from the prior art. Preferably, at least one of the coaxial through holes is provided for receiving an elongated retainer, with the possibility of adjusting the position of the segments relative to each other

Segments can also be interconnected by a coupler or by bolting.

To ensure sealing of the segments' joints between themselves, gaskets can be used, mainly from synthetic materials.

In addition, as follows from the drawing shown in FIG. 2, the center of the hole for accommodating the filter cartridge in the support ring can be offset with respect to the center of the upper base of the support ring. This arrangement allows for easy and comfortable access to the structure of the well, since floor slabs 4 can have an asymmetric arrangement of the hole 16 through which the filter cartridge is installed on the device for accommodating the filter cartridge. In this regard, to ensure the possibility of installing a filter cartridge on the described device must also have an asymmetric location of the holes for the filter cartridge.

Standard elements of wells according to GOST 8020-90 may have deviations from standard linear dimensions up to 20 mm. Therefore, the gap 12 between the ring 1 and the wall of the well 2 (Fig. 1 and Fig. 2) can have a significant width. Sealing the gap between the parts of the ring and between the ring and the walls of the well produced by the protective layer of the sealing material contribute to the achievement of the claimed technical result, since it allows you to eliminate the gap between the parts of the device for accommodating the filter cartridge and the elements of the well, thereby ensuring the necessary tightness and waterproofing.

Thus, the use as a device for placing a filter cartridge inside a sewer well of a composite support ring, consisting of segments interconnected with the possibility of adjusting the position of the segments, allows to reduce the time for its installation at the place of use, with the possibility of mounting / dismounting the device and filter cartridge inside an already constructed sewer well through the neck of a standard hatch, without dismantling the elements of the well (hatch, base plate, etc.). as well as to increase the maintainability of the device and the reliability of its application through the use of mounting elements and position fixators of the support ring in the well, as well as sealing joints of adjacent elements and gaps.
