Description

The group of inventions relates to the field of wastewater treatment, namely to filter cartridges installed in storm wells, and methods for mounting filter cartridges, in particular directly through a manhole and without installing a support ring.

From patent RU 138579 a filter cartridge housing is known, provided with a support flange-ring and containing a load.

The filter cartridge housing of RU 2225744 is also known. The device comprises an open upper end, a closed lower end, side walls between them and a connecting element. The cartridge is designed to supply the treated water to the open upper end of the filter, flowing it through the porous medium and flowing out radially outward through the side walls of the porous filter as air is displaced from the open upper end.

However, these solutions require the installation of a support ring, which requires earthwork, which increases the installation time and its cost.

The closest analogue of the inventive filter cartridge housing is a technical solution known from patent RU 138499. The housing has a lateral waterproof cylindrical wall and upper and lower permeable ends. A filter load is placed inside the housing.

The closest analogue of the proposed method is a method of mounting a filter cartridge from patent RU 138579. In a reinforced concrete well, the flange-ring is directly supported on the reinforced concrete ring. When installing a filter cartridge, a solution with liquid glass is used.

However, this filter cartridge, despite the fact that it does not require the use of a metal support ring, requires earthwork during installation, which significantly increases the cost of installing such a filter cartridge, requires additional equipment and increases the installation time.

The technical problem to be solved by the claimed group of inventions is to remove the need for earthwork and the installation of a support ring for mounting a filter cartridge.

The technical result of the claimed group of inventions is to simplify the installation technology due to the absence of the need to install a support ring and earthwork.

The specified technical result is achieved due to the fact that in the casing of the filter cartridge for a storm well containing a side surface, the permeable upper and lower bases, the upper and lower bases are made folding with the possibility of passing through the hatch of the storm well and fixing in the storm well, and the side surface is made flexible with the possibility of passing through the hatch of a storm well and placing perpendicularly between the upper and lower bases along the edge of the upper and lower bases.

The housing may further comprise a rod for locating and defining a fixed distance between the upper and lower bases.

The upper and lower bases can be made of separate elements.

Moreover, the elements of the upper and lower bases can be in the form of sectors with the possibility of the formation of a circle when combined.

In this case, the sectors of the upper and lower bases can be made with the possibility of fixing in the center of the circle.

The upper and lower bases may be provided with at least one side to abut the lateral surface.

The filter cartridge may further comprise two crosses for placement below the lower base and on top of the upper base and fixation.

The specified technical result is also achieved due to the fact that in the method of mounting the filter cartridge with the claimed housing in a storm well, including the placement of the upper and lower bases, side surface and sorbent in the storm well, the lower base is folded through the hatch into the storm well, folded and fix, then the side surface is placed through the hatch into the storm well and placed perpendicular to the lower base along the edge of the lower base, the sorbent is filled up, after which the upper base when folded, it is placed through the hatch into a storm well, laid out over the sorbent and fixed.

In the method, the first and second crosses can be additionally used, while before placing the lower base in the storm well, the first cross is placed in the last, resting on the bottom of the well, on which the unfolded lower base is placed, and the second cross is placed in the storm well after fixing the upper base.

Simplification of installation technology due to the absence of the need to install a support ring and earthwork is achieved due to the fact that the filter cartridge housing is a collapsible design of two folding bases and a flexible side surface, which allows them to be mounted directly through the storm manhole hatch in turn and not resorting to any earthwork.

The best embodiment of the inventive device is shown in the figure, in which positions 1-8 are indicated:

1 - upper base;

2 - lower base;

3 - side surface;

4 - a core;

5 - a cross;

6 - sector;

7 - ring;

8 - board.

The housing of the filter cartridge consists of upper 1 and lower 2 bases, side surface 3, rod 4 and two cross pieces 5.

The side surface 3 is made of a flexible material, for example, a galvanized iron sheet of 2 mm thickness, and when unfolded, it is a rectangular sheet.

The upper 1 and lower 2 bases consist of sectors 6, which, when combined, form a complete circle. For fixing between themselves and to the rod 4, each sector 6 is equipped with a ring 7. Sectors 6 are also equipped with sides 8, in which when installed the side surface 3 abuts.

Sectors 6 allow you to fold and unfold the upper 1 and lower 2 bases, ensuring their passage directly through the hatch of the storm well. Sectors 6 are made with holes providing water permeability to the upper 1 and lower 2 bases.

The housing can be supplemented with a sampler (not shown in Fig.), Made in the form of a pipe with a cap at the end closest to the surface and placed parallel to the rod 4 through the upper 1 and lower 2 bases. The sampler can be made of a plastic sewer pipe with a diameter of 100 mm. The sampler is intended for sampling for utilities involved in the water supply and sewerage of a city, such as Vodokanal.

For the convenience of transportation and installation, the filter cartridge is disassembled.

Assembled in the housing of the filter cartridge, one of the crosses 5 is connected to the lower base 2, which, in turn, is connected to the upper base 1 using a rod 4. Between the upper 1 and lower 2 base, abutting against the sides 8, is located lateral surface 3. Another cross 5 is connected to the upper base 1.

Crosses 5 and rod 4 can be made of d57 pipe using a stud, nut, washer and square profile 25 * 25 mm.

Sectors 6 can be made of iron-painted sheet 2 mm thick using d20 washer as ring 7. Board 8 can be made from a corner of 25 * 25 * 4 mm.

The inventive filter cartridge can be installed without crosspieces 5 and rod 4 only by fixing the upper 1 and lower 2 bases to the walls of the storm well with its small diameters and, accordingly, a small sorbent load, which the upper 1 and lower 2 bases can withstand.

The method of mounting the filter cartridge is as follows.

In a storm well directly through the hatch without any earthwork, the cross 5 is placed at the bottom of the well. Then, the lower base 2 is lowered into the storm well in the folded position, the sectors 6 are laid out to form a circle and fixed with the help of the ring 7 to the spider 5. In the middle of the lower base 2, the rod 4 is fixed. Then, the side surface 3 is lowered into the storm well, bending it in the form cylinder and resting on the sides 8 of the lower base 2. For additional fixation of the side 8 of the lower base 2 can be attached to the walls of the well, for example, dowel nails 6 * 60 mm or 8 * 60 mm. A sorbent, previously placed in mesh sleeves, for example, Novosorb, MAU, BAU, Equosorb charcoal, as well as membrane tissues, lavsan, and synthetic winterizer are poured into the formed “glass”. Then, in the folded state, the upper base 1 is lowered into the storm well, abutting the sides 8 against the side surface 3 and fixed to the rod 3. After that, the second cross 5 is lowered into the storm well 5. The second cross 5 rests when unscrewing the storm well to the top of the ceiling for structural stability, why inside the rod 4 and crosses 5 a threaded rod is provided. Under the second cross 5, the rod 4 can be equipped with a handle, during rotation of which the height of the base (spacer) will increase.

Thus, when installing the first crosspiece 5 due to expansion by rotation along the thread, it abuts against the bottom of the well, and the second crosspiece 5 - against the ceiling on which the manhole cover is installed. To remove the filter cartridge, loosen the thread inside the crosspieces 5, twist, and the spacer disappears.

Example 1

For a filter cartridge with a diameter of 2 m, the lower and upper bases contain 11 sectors, each with a chord length of 562 mm and a radius of 400 mm each, the rod has a length of 510 mm and the side surface is 1 mm thick and 6,280 mm by 525 mm in size.

Example 2

For the filter cartridge with a diameter of 1.5 m, the lower and upper bases contain 8 sectors, each with a chord length of 577 mm and a radius of 400 mm each, the rod has a length of 510 mm and the side surface is 1 mm thick and measures 4170 mm by 525 mm.

The above examples are special cases and do not exhaust all possible implementations of the claimed group of inventions.

A person skilled in the art should understand on the basis of the description that the bases can be folded according to another principle, for example, by folding the edges using articulated joints, as well as using sliding elements. The side surface can be flexible due to the design of the accordion or can be made of other flexible material, for example, durable and flexible plastic.

The claimed group of inventions allows you to quickly and without excavation work to mount a filter cartridge in a storm well, which also facilitates transportation due to its collapsible design.
