Description

Technical field

The utility model relates to the field of wastewater treatment, namely, devices for their treatment at the end of the sewer network in front of the control well.

State of the art

Known filter cartridge for water purification, filled with a filter load, comprising a housing having a lateral waterproof cylindrical wall, upper and lower permeable ends, characterized in that an outer continuous flange is additionally fixed in the upper part of the housing along the perimeter of the housing, and eyelets for slinging and moving filter cartridge (RF patent for utility model No. 138499, B01D 27/02, published March 20, 2014).

Similar solutions are described in the following utility model patents: No. 59996, B01D 27/00, published January 10, 2007; No. 149624, B01D 27/02, C02F 1/00, E03F 5/14, published January 10, 2015; No. 151523, B01D 27/02, C02F 1/28, published on 04/10/2015; No. 156036, B01D 27/02, B01J 39/08, C02F 1/28, published October 27, 2015; No. 156676, B01D 27/02, C02F 1/28, C02F 101/20, C02F 101/32; published on November 10, 2015.

The disadvantage of all of the above devices is the high complexity of the process of replacing a granular cleaning cartridge loading.

The solution described in patent No. 138499 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 filter cartridge that provides the least time-consuming, among the known, method of unloading a granular cleaning charge from a filter cartridge designed to purify water for technical and technological purposes in water circulation, as well as its discharge into water and fishery reservoirs or a city alloy sewer.

The technical result is to reduce the complexity of unloading granular cleaning material.

Hereinafter, the complexity of the process of replacing a granular cleaning material means the time it takes one person to replace the spent granular cleaning material in the filter with a new one. This parameter is one of the most important in the process of operating the filter cartridge, since the labor cost of personnel operating the filter cartridge is an essential part of all the costs of wastewater treatment on the filter cartridge, and therefore this parameter requires optimization.

The claimed technical result is achieved in that the filter cartridge for wastewater treatment, filled with a granular cleaning charge, comprises a housing having a lateral waterproof cylindrical wall, upper and lower permeable ends, in the upper part of the housing has an outer continuous flange around the perimeter of the housing and eyelets for slinging and moving the filter cartridge, and the granular cleaning charge is in the bags.

In another embodiment, the top cover of the filter cartridge is provided with a handle.

In yet another embodiment, the loading bags are interconnected. In another embodiment, the bags with cleaning charge provided with handles.

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 filter cartridge installed in a concrete well of storm sewers.

The proposed drawing illustrates 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.

Implementation of the utility model. Fig. 1 shows a schematic illustration of the inventive filter in the form of a filter cartridge installed in a reinforced concrete well for cleaning the drain in a storm sewer network, where: 1 - reinforced concrete well, 2 - supporting ring, 3 - slab of reinforced concrete well, 4 - well manhole cover, 5 - raw water inlet pipe, 6 - filter cartridge, 7 - bags with a granular cleaning charge, 8 - lower permeable end (grate), 9 - purified water outlet pipe, 10 - upper water permeable end (grille).

The filter is installed inside the concrete sewer well 1 on the support ring 2. The well is closed with a floor slab 3 and a manhole cover 4. The untreated water flows through the inlet pipe 5 into the well 1 and then through the upper mesh (grate) 10 into the filter 6 located inside the well 1 on a support ring 2, which ensures a tight location of the filter 6 between the upper and lower parts of the well and allowing the water to be cleaned to flow from one part of the well to another exclusively through the filter. Having passed the upper permeable end (grate) 10, the wastewater enters the layer of granular cleaning charge 7 located in the bags, where the cleaning takes place. Then through the lower grill 8 goes to the lower part of the well 1, from where it merges through the lower pipeline 9.

Replacement of the granular cleaning material is made through the neck of the manhole 1 with the manhole cover 4 open without removing the filter cartridge 6 from the well 1.

Reducing the complexity of replacing the granular cleaning material in the filter cartridge is achieved due to the absence of the need (as is the case in the analogues and prototype) to unload the spent cleaning material into buckets or other containers with shovels, scoops or other tools. In the claimed utility model, unloading is carried out by the method of removing from the filter cartridge bags with spent granular cleaning material, which is much easier and faster than unloading with shovels. In addition, in the case of the application of the claimed utility model, spilling of the spent cleaning material from the cartridge onto an adjacent platform is excluded, which also contributes to the achievement of the technical result, since there is no need to clean the area around the served filter cartridge.

The bags in the filter cartridge can be randomly placed or have ordered packaging. Features of the arrangement of bags with a granular cleaning charge inside the filter cartridge do not affect the achievement of the technical result. Bags can be made both from non-woven material, and from mesh or woven. The material of the bag does not affect the achievement of the technical result, but only creates options.

As a granular cleaning charge, various cleaning materials can be used (activated carbons, modified activated carbons, sulfonated carbons, natural zeolites, ion exchange resins, calcium or magnesium carbonates, peat granules). Features of particular forms of granular cleaning load do not affect the achievement of a technical result, since any granular cleaning load is much easier and faster to unload in the form of bags than in bulk, and obtaining a technical result is ensured by the fact that the granular cleaning load, if it is in bags, less difficult to remove from the filter cartridge.

Providing the upper permeable end with a lid with a handle contributes to a less time-consuming extraction of bags with a granular cleaning load (since the procedure for opening the filter cartridge before removing the granular cleaning material from it is simplified and therefore reduced in time), i.e., achieving a technical result.

The connection of the bags in one way or another with each other allows pulling one bag to remove those connected to it, which reduces the total time for unloading bags with a granular cleaning load and reduces the complexity of this process, which helps to achieve a technical result. Features of the particular forms of connection of the bags with each other do not affect the achievement of the technical result, since any connection (stitching, adhesion, soldering) allows you to pull out one bag and pull out the others connected to it.

The supply of bags with a granular cleaning load by handles also contributes to a less laborious extraction of bags with a granular cleaning load (since it takes less effort to grab a bag by hand, and with a certain standard supply of power for a person, he will be able to pull out more bags in a certain period of time), i.e., achieving technical result.

It should be noted that the claimed utility model may find application in devices having a combination of features of the claimed utility model and other distinctive features, for example: bags with a granular cleaning charge may contain filter materials, either modified or not modified, and may also be in bags only part of the granular cleaning charge, the rest of it can be in the filter cartridge in bulk. The filter cartridge can be equipped with a mesh or grill to separate large contaminants or have a lid for the separation of large contaminants. The filter cartridge can also have a bypass or a pipe for discharging wastewater, the flow rate of which exceeds the nominal capacity. The filter cartridge may have several compartments with various cleaning loads or filter elements.
