Description

Technical field

The utility model relates to the field of wastewater treatment, namely, devices for accommodating filter cartridges for wastewater treatment.

State of the art

In a number of patents (patents for inventions No. 2567173 (published on November 10, 2015 E02B 11/00) and No. 2450108 (published on May 10, 2012 E03F 5/02), a utility model patent No. 153091 (published on July 10, 2015 E02B 11/00)) describes the wells made of plastic.

The disadvantage of these devices is that they are not originally intended for installation of a filter cartridge in them, which entails difficulties in the modernization of these devices to enable the correct installation of a filter cartridge in them.

In a number of patents (utility model patents No. 59996 (published on January 10, 2007 B01D 27/00), No. 150862 (published on February 27, 2015 B01D 27/02), No. 148363 (published on December 10, 2014 B01D 27 / 00), No. 149624 (published 01.10.2015, B01D 27/02, C02F 1/00, E03F 5/14), No. 150047 (published 01/01/2015 E03F 5/14)) describes a device for accommodating a filter cartridge, assembled from standard reinforced concrete products and a steel support ring.

The disadvantage of these devices is that they consist of several (usually five or more) reinforced concrete and steel elements. The installation of these elements is time-consuming due to their large number and the large mass of each of the constituent elements. High labor intensity is also provided by the need to seal reinforced concrete and steel elements with each other.

The solution described in patent No. 150047 (published on January 27, 2015 E03F 5/14) is the closest in combination of essential features to the claimed utility model and is taken as a prototype.

Utility Model Disclosure

The objective of the claimed utility model is to develop a design for accommodating a filter cartridge for wastewater treatment, requiring minimal labor for its installation directly during construction.

The technical result of the utility model is to reduce the complexity of mounting the device to accommodate the filter cartridge.

Hereinafter, the complexity of mounting a device for placing a filter cartridge means the time it takes for a standard number of people having standard equipment with standard labor productivity to erect a structure into which a filter cartridge for wastewater treatment is installed to ensure its proper operation. This parameter is one of the most important in the process of erecting wastewater treatment systems, since the labor cost of personnel erecting such systems is an essential part of all the costs of wastewater treatment on a filter cartridge, and therefore this parameter requires optimization.

The claimed technical result is achieved in that the device for accommodating the filter cartridge, which is a cylinder with an open upper and closed lower ends, with a narrowing in the shape of a ring and a pipe located below the narrowing, characterized in that the vessel has lifting elements in the upper part, and the vessel and all its elements are made of polymeric material in the form of an integral structure.

In yet another embodiment of the utility model, the ring-shaped narrowing has stiffening ribs on the side of the closed lower end.

In yet another embodiment of the utility model, a hatch is located on the open top of the cylinder.

Brief Description of the Drawings

For a better understanding of the essence of the utility model, its description is considered with the use of the accompanying drawings.

FIG. 1. General view in section of a device for placing a filter cartridge.

FIG. 2. A particular view of the sling element shown in FIG. one.

FIG. 3. A particular view of the sling element shown in FIG. one.

The proposed drawings illustrate the preferred embodiments of the utility model and therefore cannot be considered as limiting the content of the utility model, which does not include other variants of its execution.

Utility Model Implementation

In FIG. 1 is a schematic illustration of a device for accommodating a filter cartridge, where are indicated: 1 - a device in the form of a cylinder with an open upper and closed lower end for placing a filter cartridge; 2 - narrowing in the form of a ring; 3 - drain pipe; 4 - filter cartridge; 5 - sling element; 6 - stiffeners.

In FIG. 2 and FIG. 3 shows several of the possible embodiments of the sling elements 5.

The technical result is achieved, firstly, by the fact that the device is made of a polymeric material, which provides a lower mass of the device in comparison with reinforced concrete and steel. This fact reduces the complexity of mounting the device to accommodate the filter cartridge for cleaning stormwater, because, depending on the overall dimensions of the compared products, either fewer people will be required to lift and move them, or a smaller number (or less power) of lifting equipment will be required. It should be noted that the use of fewer lifting equipment requires less personnel serving it, that is, leads to the achievement of a technical result. And also the use of a lower power lifting equipment leads to the achievement of a technical result, since its maintenance compared with more powerful lifting equipment also requires less time for maintenance of this equipment. The inventive device can be made, for example, of polyethylene, polypropylene, polyvinyl chloride, fiberglass with resin. Features of particular forms of polymer material selection do not affect the achievement of a technical result, since any polymer material has a lower density than reinforced concrete, and therefore, products from it will have a lower mass, which will contribute to the achievement of a technical result.

Secondly, the technical result is achieved due to the fact that the claimed design is integral and, therefore, requires only one act of lifting and moving its element (the only one) compared to structures consisting of several elements (in this case, reinforced concrete). Reducing the number of acts of lifting and moving parts of the device for placing a filter cartridge for wastewater treatment undoubtedly leads to the achievement of a technical result.

Thirdly, the technical result is achieved due to the fact that the claimed design has sling elements that are necessary to engage this design with lifting equipment and move the device manually. Otherwise, it would be necessary in some way to tie the device for its cylindrical part to the above devices, which undoubtedly requires a lot of labor. The lifting elements can be made, for example, in the form of a hole in the cylindrical body of the inventive device (Fig. 2) or welded eyes with a hole (Fig. 3). Features of particular forms of execution of the sling elements do not affect the achievement of the technical result, since any sling elements will contribute to the absence of the need to perform more labor-intensive operations (for example, to tie the inventive device to a cylindrical body), thereby contributing to the achievement of the technical result.

The filter cartridge installed in the described device may have large dimensions and weight, which will entail the need to strengthen the narrowing in the form of a ring inside the inventive cylinder with open upper and closed lower ends. Such reinforcement can be made in the form of adding metal inserts or other reinforcing elements at the time of installation to the device, but this procedure is quite laborious. The addition of stiffening ribs 6 of polymer material at the production stage in the design of the inventive device will eliminate the procedure for their addition during installation of the device at the facility under construction, which will undoubtedly reduce the complexity of its installation, that is, will lead to the achievement of a technical result. The stiffeners can be made, for example, in the form of square or triangular jibs. Features of particular forms of execution of stiffeners do not affect the achievement of a technical result, since any stiffeners will help strengthen the structure, and already at the production stage, and thereby reduce the complexity of strengthening (at the construction stage) of the inventive device for placing a heavy filter cartridge in it, thereby contributing to the achievement of a technical result.

In practice, in most cases, wells (in this case, a cylinder with an open upper and closed lower end), located in almost all cases underground, are closed with hatches in order to exclude the possibility of people falling there. Installation of the hatch is another stage of installation of the described device. To exclude this stage from the installation of the device (thereby reducing the complexity of its installation on the building under construction, and therefore, contributing to the achievement of the technical result), the hatch must already be mounted in the manufactured (claimed) device. The hatch can be deaf or trellised (catchment). Features of private forms of execution of the hatch do not affect the achievement of the technical result, since any hatch being already mounted in the inventive device will not have to be mounted in the inventive device at the time of erection of the treatment facilities themselves, thereby contributing to the achievement of the technical result.
