Description

Technology area

The utility model relates to the field of storm wastewater treatment, namely to devices for placing filter cartridges with a flange inside tanks, in particular, made of reinforced concrete wall rings.

State of the art

A device for placing a filter cartridge inside a sewer well is known (utility model patent No. 179142, published 04/28/2018, B01D27 / 00, E03F5 / 14)) made of reinforced concrete, made in the form of a plate having an opening for placing a filter cartridge in it, as well as metal elements protruding beyond its contour, located and made in such a way that they have the ability to mesh with the reinforcement cage of the body of the reinforced concrete well.

The disadvantage of the technical solution for the utility model patent No. 179142 is the difficulty of using it for installation on wells made of finished reinforced concrete products (for example, wall rings according to GOST 8020-2016), since in this case their partial destruction would be required to ensure that the device engages with the reinforcement the frame of these products.

It should be noted that the technical solution for the patent for utility model No. 179142 has the feature "the device is equipped with metal elements protruding beyond its contour, located and made in such a way that they have the ability to hook into the reinforcement cage of the reinforced concrete well body." The claimed device is devoid of this feature.

Known device for placing a filter cartridge inside a sewer well (utility model patent No. 155863, published 10/20/2015, E03F5 / 14)) made of reinforced concrete, made in the form of a plate having an opening for the location of the filter cartridge.

The disadvantage of all the above-described technical solutions, including the solution described in the patent for utility model No. 155863, is the weak adhesion of the devices for placing the filter cartridge with the body of the reinforced concrete well on which it is installed. The rigid adhesion of the device to the body of a reinforced concrete well is an extremely important circumstance, for example, in the construction of reinforced concrete wells in earthquake-prone regions of Russia.

The solution described in the patent for utility model No. 155863 is the closest in terms of the totality of essential features to the claimed utility model and is taken as a prototype.

Disclosure of the essence of the utility model

The objective of the claimed utility model is to develop the design of a device for placing a filter cartridge (hereinafter referred to as the device), which can be used in the construction of wells from ready-made reinforced concrete elements (for example, wall rings according to GOST 8020-2016) in earthquake-prone regions of Russia, and which excludes the shift of this device relative to a reinforced concrete well during an earthquake, or displacement of wall rings for other man-made reasons (for example, the impact of construction equipment).

The technical result of the utility model is to increase the adhesion strength of the device for placing a filter cartridge with a flange inside a container with a body made of reinforced concrete wall rings.

Hereinafter, the strength of adhesion is understood to mean the force required to carry out a shift (linear movement) of the device relative to the body of the sewer well.

The claimed technical result is achieved in that the device for placing a filter cartridge with a flange inside a container, the walls of which are made of reinforced concrete wall rings, is made in the form of a plate having an opening for placing a filter cartridge in it, and this plate has additional holes in the end region of its outer the edges.

Figure 2. Top view of the claimed device.

The proposed drawings 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 versions of its implementation.

Implementation of the utility model

Figures 1 and 2 show a schematic representation of the inventive device, where are indicated: 1 - device, 2 - wall ring of the well, 3 - hole for placing a filter cartridge in it, 4 - additional holes in the end region of the outer edge of the device, 5 - cement mortar, 6 - filter cartridge, 7 - filter cartridge flange.

The feature of the utility model "for placing a filter cartridge with a flange inside a container, the walls of which are made of reinforced concrete wall rings", inherent in the limiting part of the formula of this utility model, is an essential feature and a prerequisite for achieving a technical result within the field of technology of the claimed device, since

a) provides the relationship between the claimed device and the prototype, which is also inherent in this feature;

b) refers the device to its inherent technical field, and therefore is an essential feature and a necessary condition for achieving a technical result within the technical field of the claimed device.

The feature of the utility model "made in the form of a plate" inherent in the limiting part of the formula of the present utility model is an essential feature and a necessary condition for achieving a technical result within the technical field of the claimed device, since

a) provides the relationship between the claimed device and the prototype, which is also inherent in this feature;

b) the shape of the device in the form of a plate, in contrast to other forms (for example, a ball, torus, cone, pyramid), allows it to be fixed between the wall reinforced concrete rings of the well in the simplest and most reliable way.

The feature of the utility model "having an opening for placing a filter cartridge in it", inherent in the limiting part of the formula of this utility model, is an essential feature and a necessary condition for achieving a technical result within the technical field of the claimed device, since

a) provides the relationship between the claimed device and the prototype, which is also inherent in this feature;

b) refers the device to its inherent technical field, and therefore is an essential feature and a necessary condition for achieving a technical result within the technical field of the claimed device.

The feature of the utility model "the plate has additional holes in the end region of its outer edge", inherent in the distinctive part of the formula of the present utility model, is an essential feature and a necessary condition for achieving a technical result within the technical field of the claimed device, since

provides a connection due to the cement mortar 5 not only of the connections "device - wall ring above the device" and "device - wall ring under the device", but also connections "wall ring above the device - wall ring under the device", due to that part of the cement mortar, which falls into these additional holes. This leads to a more reliable fixation of the device between the wall rings, not only due to the adhesion forces between the surface of the device and the cement mortar, but due to the strength of the cement screeds located in the additional holes. In this case, to carry out a shift (linear movement) of the device relative to the body of the sewer well, it will be necessary not only to tear off the cement mortar from the device, but also to destroy the cement screeds formed by additional holes, which will undoubtedly lead to the achievement of a technical result.

The peculiarities of the particular forms of the device in terms of the material from which the device is made do not affect the achievement of the technical result, which is provided in any of the cases inherent in a given degree of generalization of the feature, since

holes in a plate made of any material will allow the cement slurry from the area above the device to connect and the cement slurry from the area below the device, which in any case will increase the strength of such a connection, that is, ensure the achievement of a technical result.

This generalized feature can be implemented in various material carriers, for example, in variance: plastics of any kind, steels, composite materials.

The peculiarities of the particular forms of the device in terms of the number of holes do not affect the achievement of the technical result, which is provided in any of the cases inherent in a given degree of generalization of the feature, since:

Even one hole will allow the cement slurry from the area above the device to connect and the cement slurry from the area below the device, which in any case will increase the strength of such a connection, that is, ensure the achievement of a technical result.

An increase in the number of holes will only lead to a more significant increase in the strength of such a connection, but the fact of achieving a technical result will not change from this.

The peculiarities of the particular forms of the device in terms of the shape and size of the holes do not affect the achievement of the technical result, which is provided in any of the cases inherent in a given degree of generalization of the feature, since

even a round hole of the minimum size will allow the cement slurry from the area above the device to connect and the cement slurry from the area below the device, which in any case will increase the strength of such a connection, that is, ensure the achievement of a technical result.

An increase in the number or area of the side surfaces of additional holes (the transition from a round hole to a triangular, tetrahedral, pentahedral, and so on) will only lead to a more significant increase in the strength of such a connection, due to the greater adhesion of the cement mortar to the side surface of the hole, but the fact of achieving a technical result from that won't change.

The peculiarities of the particular forms of the device in terms of generalizing the location of additional holes as "in the end region of its outer edge" do not affect the achievement of the technical result, which is provided in any of the cases inherent in a given degree of generalization of the feature, since:

According to the technical field of the claimed device, it is always located inside the containers. Therefore, the device cannot protrude beyond the boundaries of the container, since in this case it would be partially outside the container, that is, not inside the container. It should also be noted that at least a part of the device must be located exactly between the wall rings (be clamped between them), since otherwise the device will fall to the bottom of the container and cannot be used to accommodate the filter cartridge. As a result, the outer edge of the device will always be between the wall rings.

The wall ring, above or below which the device is located, always has a width greater than zero, but can potentially have both small and large widths. Due to the fact that wall rings can be manufactured both in accordance with GOST 8020-2016 and in accordance with any other regulatory documents, it is not possible to normalize the width of the wall ring.

Consequently, the end region of the outer edge of the device is formed on the one hand by an arbitrary outer diameter of the wall ring (cannot exceed it), and on the other hand by an arbitrary thickness of this wall ring. In other words, the width of the area of the outer edge of the device does not depend on the device itself, but depends only on the design of the wall rings used with it.

It should be noted that the reverse is also true. For the inventive device with any width of the region of the outer edge, a wall ring of such a diameter and width can be selected (or manufactured) that the region of the outer edge of the device will be completely sandwiched between two such wall rings.

If additional holes are found in any part of this area, a technical result will be achieved, since this hole will allow the cement slurry from the area above the device to connect and the cement slurry from the area below the device, which in any case will increase the strength of such a connection, that is, ensure the achievement of the technical result ...

The claimed device will find wide application in Russia, since sewer wells are made of ready-made reinforced concrete elements in accordance with GOST 8020-2016 throughout Russia, and the requirements for high strength of the connection between the well and the wall rings are imposed not only in earthquake-prone regions (of which there are also many in Russia), but also in ordinary ones, when users of such sewer wells are interested in increasing their durability.
