Description

The utility model relates to devices for providing water supply to the population with drinking water and can be used in the national economy for individual water supply to industrial buildings, residential houses, cottages, summer cottages where there is no centralized water supply.

There are many devices for supplying water to the consumer: by gravity from a higher level to a lower one, water towers, pumps, pumping stations. The most modern device for supplying water to the consumer are pumping stations. Pumping stations are currently used in almost all sectors of the economy (industry, agriculture, oil production, etc.)

There are a huge number of companies in the world manufacturing pumps and pumping stations - Grundfos (Denmark-Germany), Pentax, Nocchi, Speroni (Italy), Leader (China), Gileks (Russia), Calpeda, etc., which differ from each other in type pumps: centrifugal, circulating, rotary, ejector; location: submersible, borehole, as well as types of membrane tanks. The membrane tank serves to maintain working pressure in the water supply system and for water supplies. Membrane tanks are horizontal and vertical, and by design the tank can be:

- detachable - provides for the possibility of replacing the membrane during operation,

- one-piece - excludes membrane replacement. Pumping stations allow you to automate the process of supplying water from a well, well, reservoir. They are an electric pump mounted on one base and a small 20-25 liter membrane tank weighing 12-22 kg and can be portable.

Known pumping station Hydrojet company Grundfos (Denmark-Germany) based on the pump JP (www.multipumps.ru/ Pumping station. Pumping station for water supply Grundfos. Pumping station Hydrojet JP. VST magazine "Water supply and sanitary equipment", 2008, No. 1 pp. 20-21).

This pumping station is a complete system that includes an ejector pump, an electric motor, a diaphragm pressure tank, a pressure and water flow control system.

The pump station is designed to provide uninterrupted water supply to individual houses, cottages, summer residences, farms and other consumers from reservoirs, wells, wells and other sources of deep water bedding in automatic mode. Thanks to the ejector pump, the pumping station works reliably in self-priming mode in automatic mode throughout the entire service life.

The main disadvantage of this pumping station is the provision of low quality water, as the main sources of water intake are water bodies, wells, wells, in which the likelihood of contamination with pathogenic microflora, biological and other pollution is very high. And the set of this pumping station does not specify a mechanical filter, which usually equips such stations, at least for cleaning water from sand, silt and other mechanical impurities. Therefore, the water supplied by the pumping station is most often unsuitable for food purposes without additional purification.

The closest to the claimed utility model by the set of essential features among the known analogs is the Pentax, Italy type Pump Station, with the CAM, CAB, INOX, JMS series pumps (passport and operating instructions, 1997, Moscow Pumping Plant OJSC). The device of such a pumping station consists of a centrifugal pump, an electric motor, a hydraulic accumulator with a replaceable membrane made of food rubber, a pressure switch, a pneumatic valve, a pressure gauge, and a mechanical filter (Fig. 1). This pump station is manufactured in Russia and is designed to provide uninterrupted water supply to cottages, cottages, farms and other consumers with water intake from wells, reservoirs, wells and other sources of deep water (8-9 m) in automatic mode. In the technological scheme (Fig. 2) of this station there is a mechanical filter for cleaning water from sand, silt and other mechanical impurities. However, such purification does not yet make water suitable for food purposes.

Therefore, this pump station without additional purification does not provide the consumer with drinking water of the required quality, as it is used for individual water supply to consumers where there is no centralized water supply with drinking water, and where the main sources of water intake are water bodies, wells, wells, in which the probability of contamination by pathogenic microflora , biological and other pollution is very high.

Other pumping stations that provide drinking water of the required quality are unknown.

The technical result of the utility model is to provide the pumping station of the consumer with drinking water of the required quality and increasing the efficiency of the pumping station.

The technical result provided by the utility model is achieved by the fact that in this utility model comprising a pump, an electric motor, a water flow and pressure control system, a mechanical filter, a pressure head membrane tank, and a flocculation device, a device are additionally integrated in the line between the pump and the membrane tank for disinfection and an analyzer of chlorine in water with a switch for analyzing chlorine in the source and purified water, and the mechanical filter is additionally equipped with an automatic washing system contaminated filters, while the main water treatment units of the pumping station are located in the following sequence: a flocculation device, a mechanical filter, a disinfection device and an analyzer of chlorine in water, and the control unit is connected to a computer on the one hand and to the flocculation device on the other , pump, flowmeter, mechanical filter, disinfection device, chlorine analyzer in water and a membrane tank.

Providing the consumer with drinking water of the required quality with the help of a pumping station is achieved due to the fact that the additional introduction of a flocculation device into the pumping station allows colloidal contamination of organic and mineral nature in water in the form of turbidity, color, opalescence to aggregate loose, flocculent sediments, which can filter on a mechanical filter. An additional introduction of a disinfection device allows you to destroy the pathogenic microflora, additionally remove the yellowness of water by oxidation of 3-valence iron and remove the unpleasant odor of water. The introduction of an analyzer of chlorine in water allows you to control and dose the required concentration of chlorine in water during disinfection.

The required quality of drinking water is also achieved thanks to the declared mutual arrangement of the components of the pumping station. The flocculation device is located at the inlet of the source water immediately after the pump. A mechanical filter is located behind the flocculation device. The mechanical filter is additionally equipped with an automatic washing system, which is periodically activated according to a predetermined program for washing dirty filters. A disinfection device is integrated between the mechanical filter and the membrane tank. An analyzer of chlorine content in purified water is built into the water supply line between the disinfection device and the membrane tank. The analyzer additionally has a switch for analyzing the source water not only after disinfection, but also at the input of the source water if the source of the intake is a centralized network where the water is already decontaminated with chlorine. And a control unit with computer software

electrically connected in parallel with a flocculation device, an electric pump, a flowmeter, a mechanical filter, a disinfection device, a chlorine water analyzer and a membrane tank.

The claimed sequence of mutual arrangement of the main nodes of the station contributes to a more effective treatment of water from pollution. In the flocculation apparatus, organic and mineral contaminants in the form of colloidal solutions, turbidity, opalescent films that easily pass through any mechanical filter, becoming aggregate in the form of loose, flocculent precipitates, are filtered by a mechanical filter simultaneously with mechanical impurities, sand and silt. Cleaner water is supplied for further purification and in the disinfection device, the disinfecting medium is spent more efficiently only on the destruction of pathogenic microflora. The analyzer of the chlorine content in water monitors the chlorine content in the purified water and, if there is not enough chlorine in the purified water, it automatically doses the amount of chlorine to the required amount. Parallel connection of the control unit with the main links of the station allows for the supply, purification of water and its disinfection in automatic mode.

Fig. 3 shows a pumping station, general view. The pumping station consists of a source water supply system made in the form of water supply pipelines 1 on which water supply taps 2 are installed and contains a pump 3, an electric motor 4, a flowmeter 5, a flocculation device 6, a mechanical filter 7, a disinfection device 8, an analyzer the chlorine content in water 9, connected via a switch 10 to the line of the original 1 and purified water 11, a membrane tank 12 and a control unit 13 connected to a flocculation device 6, pump 3, a flow meter 5, a mechanical filter 7, a device for disinfection 8, a chlorine analyzer in water 9 and a membrane tank 12. The flocculation device 6 consists of a flocculant tank 14 connected to a metering pump 15, which is connected to a control unit 13. The disinfection device consists of a disinfectant tank 16, connected with a metering pump 17, which is connected to the control unit 13. The analyzer of chlorine content in water 9 is additionally equipped with a switch 10 for analyzing the source water, when the source of water intake is a centralized network and chlorination is already provided for. The mechanical filter is additionally equipped with an automatic washing system for 18 contaminated filters. The participation of a person in the process of purification and disinfection of water, if necessary, is provided by a computer 19 connected to the unit at the board 13.

The supply of drinking water to the consumer using a pumping station is as follows. After the installation and installation of the pump station, before the first start-up, all nodes of the station are prepared for operation: the flocculation device is filled with a flocculant. As a flocculant, you can use any flocculant recommended for

specific source of the area. The mechanical filter is filled with filter material (silica sand, activated carbon, etc.). The disinfection device is filled with a disinfectant solution. A metering pump is used as a disinfection device, and sodium hypochlorite, for example, is used as a disinfectant. The chlorine analyzer is configured to measure the required concentration of chlorine in the water.

When the station is first launched, the source water supply tap on the pipeline opens, the station control unit is turned on, the pump is turned on and the entire line is filled with water. The source water enters the flocculation device, then it is fed to a mechanical filter, and purified from aggregate and mechanical impurities it enters the device for disinfection. Water, purified from all impurities and pathogenic microflora, odorless and clarified, enters the storage membrane tank until it reaches the specified maximum pressure and then the control unit turns off the pump and stops the flow of water. The station is ready to provide consumers with clean drinking water and regular use of drinking water begins. To do this, a tap with water is opened (for example, in a kitchen or in a bath), water from a membrane storage tank under pressure begins to flow into the tap and the pressure in the system decreases as the water in the tank decreases. When the pressure in the tank drops to the minimum allowed, the pressure switch installed in the membrane tank will turn on the pump and the pump will operate by supplying water to the membrane tank and the consumer until the required maximum pressure is reached in the membrane tank and then the pressure switch will turn off the pump again. When the pump is turned on, the control unit includes a flocculation device, a mechanical filter, a disinfection device and an analyzer of chlorine in water, and when the pump stops supplying water, the control unit turns them off. And so again, until the next opening of the water tap, the pumping station will automatically supply drinking water to the consumer.

Thus, the proposed design of the pumping station allows you to provide an individual consumer, where there is no centralized water supply, with clean drinking water of the required quality. The inventive design of the pumping station provides an uninterrupted supply of drinking water in an automatic mode from sources of water intake, such as reservoirs, wells, wells, the likelihood of contamination by pathogenic microflora and other hazardous pollution is very high.

Improving the efficiency of the pumping station is achieved due to the declared sequence of the relative positions of the main nodes of the water treatment of the pumping station and the use of a mechanical filter with automatic washing of dirty filters.
