A device is known for placing a filter cartridge inside a sewer well (utility model patent No. 179142, published 04/28/2018, B01D 27/00, E03F 5/14), made in the form of a solid metal ring having an opening for the location of the filter cartridge and protruding behind its contour are metal elements arranged and made in such a way that they can be hooked onto the reinforcing cage of the reinforced concrete well body.

The disadvantage of all the above technical solutions is that the load from the filter cartridge mounted on the device for accommodating the filter cartridge is distributed on the wall of the well, which forces them to increase their thickness.

The solution described in the patent for utility model No. 179142 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 the design of a device for accommodating a filter cartridge (hereinafter the device), which will allow the use of filter cartridges in wells with thin walls (for example, plastic or fiberglass).

The technical result of the utility model is to reduce the load from the filter cartridge on the wall of the well.

Hereinafter, by reducing the load from the filter cartridge on the wall of the well is meant the force with which the filter cartridge installed on the device presses on the adjacent walls of the well in which it is installed.

The increased load on the walls of the wells leads to their gradual deformation (wells made of elastic plastics, for example, polyethylene), cracking under dynamic load (replacing filter cartridges in reinforced concrete wells) or even destruction (replacing filter cartridges in wells made of brittle materials, for example fiberglass ) All this leads to the need for frequent repair of wells, which is very expensive, and sometimes impossible.

Filter cartridges usually have significant dimensions (up to 2 meters in diameter and height) and weight (up to 4 tons), and therefore have a significant load on the walls of the well in contact with them.

The peculiarity of the prototype device, namely the presence in its composition of metal elements located and made in such a way that they have the ability to engage the reinforcing frame of the reinforced concrete well body:

a) can only be used for reinforced concrete wells and is not applicable for plastic and fiberglass wells;

b) does not remove the load from the walls of the well, but only distributes it from the ends of the wall reinforced concrete rings to their reinforcing cage, which increases the strength of this coupling, but does not reduce the thickness of the walls of the well, which ultimately accounts for the load.

Based on the foregoing, it is obvious that reducing the load on the wall of the well is ultimately an important goal and leads to lower operating costs for treatment facilities in general and for maintenance of the wells themselves in particular.

The claimed technical result is achieved in that the device for accommodating the filter cartridge with the flange, made in the form of a plate, having an opening for the location of the filter cartridge in it, is equipped with elements connected to it, arranged and made in such a way that they can be supported by the bottom of the well.

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 of the inventive device in the well.

FIG. 2. General view of the prototype device in the well.

FIG. 3. An embodiment of an analog device in a well.

The proposed drawing in FIG. 1 illustrate only one preferred embodiment of the utility model and therefore cannot be considered as limiting the content of the utility model, which does not include other options for its execution.

Utility Model Implementation

In FIG. 1 is a schematic representation of the inventive device in a well; FIG. 2 - prototype devices in the well, in FIG. 3 - analog devices in the well, where: 1 - the device, 2 - elements arranged in such a way that they can rely on the bottom of the well, 3 - filter cartridge, 4 - load zone (part of the well onto which the load is transferred from the installed filter cartridge), 5 - sewer well, 6 - filter cartridge flange.

In FIG. 1 and FIG. 2, the filter cartridge 3 (having a significant mass) transfers the load to the device 1, which in turn transfers the load to the well elements connected to it.

When comparing FIG. 1 and FIG. 2, it becomes obvious that in the case of the claimed device, the load on the wall of the well disappears and goes to the bottom of the well (moreover, the compression load is evenly distributed between the supporting elements and directed clearly perpendicular to the base of the well, which is more preferable compared to the bending load of the prototype device ), which makes it possible to use wells with thin walls for installing filter cartridges in them. The bottoms of the wells, as a rule, are much thicker and more massive than their walls (often the basis for plastic wells is a reinforced concrete slab that does not allow the well to push into the ground), and therefore the additional load on the bottom will not be so significant for the design of the well as a whole.

It should be noted that in FIG. 2, the load from the filter cartridge leads to the deflection of device 1, which in turn creates asymmetric load zones (compression zones) on both parts (upper and lower) of the well connected to device 1. And such loading inevitably leads to the gradual destruction of the ends of the wall rings of the well .

In the case when the analog device is welded to the walls of the well (possibly for plastic wells made of polyethylene, shown in Fig. 3), the situation will be similar to that shown in Fig. 2, namely, during loading, the welding connecting the wall of the well and the device will gradually be destroyed.

Elements 2, having the ability to rely on the bottom of the well, can be made of rods, pipes, corners or plates, have a straight or curved shape. Features of particular forms of execution of elements with the ability to rely on the bottom of the well do not affect the achievement of the technical result, since any elements connected to the device and able to rely on the bottom of the well will reduce the load from the filter cartridge on the wall of the well, thereby achieving technical result.

A device made in the form of a plate having an opening for arranging a filter cartridge in it may have a round, rectangular or other shape. Features of particular forms of the device’s execution do not affect the achievement of the technical result, since the elements connected to the device and having the ability to rely on the bottom of the well will reduce the load from the filter cartridge on the wall of the well, thereby ensuring the achievement of the technical result.

The device, made in the form of a plate having an opening for the location of a filter cartridge in it, can be made of any material (including (but not limited to) plastic and metal). Features of particular forms of the device’s execution do not affect the achievement of the technical result, since the device made of any material will transfer the load to the elements connected to it and having the ability to rest on the bottom of the well, thereby reducing the load on the well’s filter cartridge, thereby thereby ensuring the achievement of a technical result.

A device for accommodating a filter cartridge must be made in the form of a plate in order to ensure uniform loading of the device with a filter cartridge with a flange. It should be noted that for the same reason, all analog devices and the prototype device are a ring, which in turn is a special case of the plate.

A device for accommodating a filter cartridge must have an opening for positioning a filter cartridge in it to provide technical feasibility to use it together with a filter cartridge.

The inventive device for placing a filter cartridge will be widely used in industry for cleaning storm water in plastic wells, which are currently widely used in Russia due to their low price and long service life.
