Description

Technical field

The technical solution relates to the field of wastewater treatment, and in particular to devices for cleaning storm water from suspended solids, synthetic surfactants, oil products and other contaminants installed at the end of the sewer network in front of the control well or in storm water wells.

State of the art

From the prior art there are several technical solutions of the same purpose as the claimed utility model. In particular, the filter cartridge according to the utility model patent RU No. 36260 is known, the information was published on March 10, 2004, comprising a housing with an inlet (outlet) channel for a liquid (gas) and filter elements, characterized in that, in order to increase the performance and dirt capacity of the filter, the duration of its operation to allowable pollution, reduce hydraulic resistance, energy consumption, specific dimensions, weight, manufacturing cost and improve reliability, the housing contains a container in the bottom of which there are channels with p Normal distance L between the axes of adjacent channels nf d dnf L-150 + 150 mm, where d nF - the outer diameter of the filter element, which filter elements are connected.

From the patent for utility model RU No. 46194, published on June 27, 2005, a filter cartridge is known consisting of a body made in the form of a glass and a cover with a skirt, characterized in that the bottom of the body and the cover skirt are made by double perforation.

Also known from the prior art is a filter cartridge for water purification, comprising a charge comprising a fibrous mechanical filter material and a hydrophobic granular material, characterized in that the filter charge contains lavsan and synthetic winterizer or mineral fiberglass as a fibrous material, and modified nitrogen-containing coal as a granular material and a grill for preliminary mechanical water purification is installed above the filter load (patent for utility model RU No. 59996, published Vanir 10.01.2007). This utility model is the closest analogue. Both technical solutions represent a filter cartridge for water purification, contain a load comprising a fibrous mechanical filter material and a hydrophobic granular material. The disadvantage of this utility model is the need to use a metal support ring to install a filter cartridge at the end of the sewer network in front of the control well or in storm water inlets. In addition, the utility model does not include a device that provides emergency discharge with a large flow of wastewater.

Disclosure of a utility model.

The objective of the utility model is to develop the design of the filter cartridge, expanding the arsenal of technical means for installing it at the end of the sewer network in front of the control well or in the storm water wells, namely, to develop a design that allows the installation of the filter cartridge without the use of a metal support ring. In addition, the objective of the utility model is to provide the technical feasibility of emergency drainage of liquid with a large flow of wastewater,

The technical result consists in expanding the arsenal of technical means for installing a filter cartridge at the end of the sewer network in front of a control well or in storm water inlets, namely, in providing the possibility of installing a filter cartridge without using a metal support ring. In the embodiment of the utility model, emergency drainage is also possible with a large flow of wastewater.

The technical feasibility of installing a filter cartridge at the end of the sewer network in front of the control well or in the sewage wells without using a metal support ring is achieved by the fact that the filter cartridge housing for cleaning storm drains, containing a load including a fibrous mechanical filter material and a hydrophobic granular material, is equipped with a support flange ring of low pressure polyethylene (HDPE).

As a fibrous mechanical filter material, synthetic winterizer, synthetic winterizer, lavsan, mineral fiberglass are used. As a hydrophobic granular material, nitrogen-containing carbon, activated carbon of various grades are used, for example, Silcarbon (Silcarbon), WNC carbon (WNC carbon). Features of particular forms of fibrous mechanical filter materials and hydrophobic granular materials do not affect the achievement of the claimed technical result. Obtaining the claimed technical result is ensured by the general characteristics of these materials.

In a variant of the technical solution, the filter cartridge is additionally equipped with a device for emergency discharge in a large flow of wastewater. The device for emergency discharge in conditions of a large flow of wastewater is a through pipe made of HDPE built into the filter cartridge housing, at the top of which a 180-degree removable tap is installed.

Brief Description of the Drawings

The essence of the utility model is illustrated by drawings. Figure 1 shows a filter cartridge installed in the middle of the well, where 1 is a reinforced concrete well, 2 is a flange ring, 3 is a filter cartridge housing, 4 is a fibrous filter material, 5 is a grained filter material, 6 is a solution, 7 is a plate overlapping, 8 - removable tap, 9 - pipe.

Figure 2 shows a filter cartridge installed directly under the hatch, where 1 is a reinforced concrete well, 2 is a flange ring, 3 is a filter cartridge housing, 4 is a fibrous filter material. 5 - granular filter material, 6 - solution, 7 - floor slab, 8 - removable tap, 9 - pipe.

Utility Model Implementation

The design of the support flange-ring is made of HDPE. Flanges 2 (figure 1 and figure 2) are welded to the housing of the filter cartridge 3 (figure 1 and figure 2). The fastening of the flange to the filter can be strengthened by welded scarves from HDPE on top and, if necessary, from below, depending on the design and weight of the filter. The size of the support ring-flange depends on the type of filter. For example, the diameter of the ring flange for a filter of the "Fipos-1" type is 630-750 mm, for the "Fipos-2" - 900-1000 mm, for the "Fipos-3" - 1200-1600 mm, for the "Fipos-4" - 1800-2100 mm.

In the reinforced concrete well 1 (FIG. 1), the flange-ring 2 (FIG. 1) rests directly on the reinforced concrete well (well ring). This design allows the installation of the filter without the use of a metal support ring, due to which the claimed technical result is achieved. When installing filters between reinforced concrete rings, a flange-ring is supported on each wall of a reinforced concrete ring of 50 mm, which makes it possible to tightly seal the joint both inside and out. For example, a filter cartridge with a diameter of 1200 mm is installed in a reinforced concrete well with a diameter of 1500 mm, and the diameter of the ring flange required to hold the filter cartridge will be 1600 mm, i.e. the supporting flange-ring will rest on a reinforced concrete ring of 50 mm on each side. When installing a filter cartridge, a solution with liquid glass is used. When installing the filter cartridge directly under the hatch, the flange-ring rests on the slab of the well 7 (figure 2) regardless of its diameter.

In a variant of the utility model, the filter cartridge is additionally equipped with a device for overflowing water in a large flow of wastewater. For this, a through pipe of HDPE 9 is installed inside the filter cartridge housing (Fig. 1 and Fig. 2). During testing, the claimed technical result was achieved using a pipe with a diameter of 63 mm. At the top of the pipe, a removable bend is fixed at 180 degrees 8 (Fig. 1 and Fig. 2). The presence of a drain eliminates the ingress of dirty water into the overflow system during normal wastewater flow. When a reinforced concrete well is flooded, water enters a through pipe, resulting in emergency drainage. A device for overflowing water is also used to collect samples of purified water, for which a tap 8 is first removed (FIG. 1 and FIG. 2).

After installing the filter cartridge, the device operates as follows. Purified water enters the reinforced concrete well 1 through the hatch (Fig. 1 and Fig. 2) or through storm sewers (Fig. 1). Next, the purified water flows by gravity from above into the filter cartridge housing 3 (FIG. 1 and FIG. 2), where it successively passes through the fibrous filter material 4 and the granular filter material 5. After that, the purified water either enters the process or is discharged into the collector. When the reinforced concrete well 1 is flooded, the purified water enters the through pipe 9. As a result, the water passes through the housing of the filter cartridge 3, bypassing the fibrous filter material 4 and the granular filter material 5.
