Utility Model Disclosure

The objective of the claimed utility model is to develop a design for placement of a filter cartridge for wastewater treatment, providing the most uniform quality of wastewater treatment with a filter cartridge.

The technical result of the utility model is to increase the uniformity of the intensity of the flow of untreated water through the filter cartridge.

Hereinafter, by increasing the uniformity of the intensity of the flow of untreated water through the filter cartridge, we mean the maximum leveling of productivity with which the raw rainwater is fed to the filter cartridge taken over a long period of time, covering both several periods of direct rainfall and several dry periods between rains. In other words, by increasing the uniformity of the intensity of the flow of untreated water through the filter cartridge, we mean such a change in the dependence of the instantaneous volume of rainfall passing through the filter cartridge on time that reduces the average deviation (taken modulo over a period of time covering both positive and negative deviations ) from zero the first derivative of this dependence to a minimum.

The parameter "increasing the uniformity of the intensity of the flow of untreated water through the filter cartridge" is one of the most important during the operation of the filter cartridge, since the speed with which the drain passes through the filter cartridge determines the quality of water treatment on it (this fact is described, for example, in " Klyachko, V.A. Purification of natural waters [Text] / V.A. Klyachko, I.E. Apeltsin. - M.: Stroyizdat, 1970. - 579 p. "). The higher this speed, the lower the cleaning quality, and vice versa. On the other hand, too low a water supply rate to the filter cartridge does not provide the required system performance for treated water. Typically, filter cartridges work in a certain range of water flow rates, optimal from the point of view of the ratio of productivity and degree of purification, the maintenance of which is ensured by adjustment. In other words, increasing the uniformity of the intensity of the flow of untreated water through the filter cartridge leads to the stable operation of treatment facilities, which simplifies the obtaining of a predictable and desired result of the quality of treatment.

The claimed technical result is achieved in that the device for accommodating the filter cartridge, which is a hollow body with an open upper end and a restriction for installing the filter cartridge, provided below the narrowing of the discharge pipe, is equipped above the narrowing of the supply pipe equipped with a device that allows you to adjust the intensity of the water supply to the filter cartridge.

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 drawing.

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

The proposed drawing illustrates only one preferred embodiment of the utility model and therefore cannot be construed 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 illustration of a device for accommodating a filter cartridge, where are indicated: 1 - filter cartridge; 2 - a device for accommodating a filter cartridge, which is a hollow body; 3 - open upper end; 4 - narrowing to install a filter cartridge; 5 - outlet pipe; 6 - inlet pipe; 7 - an adjustable part of the device that allows you to adjust the intensity of the water supply to the filter cartridge; 8 - water level; 9 - the regulatory part of the device, which allows you to adjust the intensity of the water supply to the filter cartridge.

In FIG. 1 a device that allows you to adjust the intensity of the flow of water through the filter cartridge 1 is shown by the example of a combination of an adjustable part 7 (in this example, an electric pump) and a regulating part 9 (in this example, a float level sensor). The electric pump delivers water to the compartment above the filter cartridge 1 with a constant volumetric feed rate, thereby raising the water level 8 above the filter cartridge, which is constantly reduced due to the flow of water through the filter cartridge into the compartment below the filter cartridge. The float level sensor signals to the adjustable part of the device that the water level has dropped below the required lower value, and it is necessary to turn on the pump, and then it signals that the water level has reached the required upper value, and it is necessary to turn off the pump (or turn it on and off).

The technical result is achieved by the fact that a device that allows you to adjust the intensity of the water supply to the filter cartridge, provides a fluctuation of the water level 8 in some small limits, which in turn leads to small fluctuations in the hydrostatic pressure of the water on the filter cartridge, which in turn ensures uniformity of intensity the flow of untreated water through the filter cartridge.

It should be noted that a device that allows you to adjust the intensity of the flow of water through the filter cartridge can be implemented differently. For example, the pump can be diesel, pneumatic or otherwise, or if water is already supplied to the device for accommodating the filter cartridge with some pressure, it can be replaced by a valve of any design, which will also act as an adjustable part of the device. The float sensor can be replaced by one or more sensors of any other design (mechanical, electrical, capacitive, ultrasonic, radio wave, microwave, hydrostatic or other), which will also serve as the regulatory part of the device. Regulated and regulating functions can also be combined in one device, for example, if a pump is used that has such a pumping capacity that is sufficient to raise the water level above the filter cartridge only to a certain height. Thus, the features of private forms of execution of the device, which allows you to adjust the intensity of the water supply to the filter cartridge, do not affect the achievement of the technical result, which is provided by the general features of this device.

It should be noted that the device for accommodating the filter cartridge, which is a hollow body, can have any design and shape. Features of particular forms of execution of the device for accommodating the filter cartridge, which is a hollow body, do not affect the achievement of the technical result, which is ensured by the fact that this body is hollow, and therefore it is able to accumulate a cleaned drain. A device for placing a filter cartridge, which is a hollow body, can be made, for example, in the form of a standard sea or railway container or part thereof (these bodies have high strength and are conveniently transported by standard equipment) or can be placed in its part.

It should be noted that in the actual implementation of the claimed device:

a) its upper open end may be provided with a cover to ensure the integrity of the structure;

b) it can be equipped with a device for heating, which will allow to operate it in the winter period;

C) a device that allows you to adjust the intensity of the water supply to the filter cartridge, can be placed in the compartment, which is structurally part of the above-described hollow body, to simplify the transportation procedure of the inventive device.

The “hollow body” sign is essential, since otherwise the body will be full and it will be impossible to install a filter cartridge inside it.

The sign “with an open upper end” is essential, since it is necessary to provide the possibility of installing a filter cartridge inside the device, which is easiest to do through the open upper end.

The sign of “narrowing to install the filter cartridge” is essential, because, firstly, the closed part of the narrowing is necessary to ensure separation of the purified and purified water, and secondly, the open part of the narrowing is necessary to ensure the installation of the filter cartridge on this boundary.

A supply pipe above the restriction is necessary to ensure a continuous supply of purified water to the device, that is, to ensure its efficiency over time.

A discharge pipe below the restriction is necessary to ensure continuous removal of purified water from the device, that is, to ensure its efficiency over time.

The inventive device for accommodating a filter cartridge will find wide application in industry when cleaning stormwater, since throughout Russia periods of intense rainfall alternate with dry periods, which requires the accumulation and uniform cleaning of this drain for a long period of time.
