Description

The utility model relates to the field of water supply, in particular, to constructive means for purifying drinking water from surface and underground sources or for post-treatment of water from centralized water supply.

A device for water purification is known that contains a reservoir for source water, filter blocks and a piping system, an opening is made in the lower part of the tank for sludge discharge and for supplying water to the filter blocks (certificate for utility model of the Russian Federation 37468, published April 27, 2004).

A known installation for water purification, mainly slow filtering, taken as a prototype (Certificate for a utility model of the Russian Federation 25318, published September 27, 2002), containing one unit consisting of a housing and a tank installed in it, with a filter load located in it, and a system of means organization of the fluid flow, a settling tank, which is connected by means of organizing the input fluid flow with the unit.

Known devices require constant monitoring of their condition during operation, because it is necessary to control how much unfiltered water remains in order to top up it, to control and discharge the sludge, which is also done manually as the sludge appears, therefore all manipulations with level control and topping up the filtered water, draining the sludge complicate the maintenance of the device, require considerable time for filter maintenance .

In known filtering devices, mainly slow filtering, there is a general problem with limiting their widespread use, which consists in the need for constant monitoring of the filtering process.

The task to which the claimed technical solution is directed is to develop a device design that automates the processes occurring in the filter device by adding a low-voltage electrical water treatment control circuit.

When implementing a technical solution, the task is achieved by providing a technical result, which consists in the complete automation of the process of water purification and sludge discharge.

The specified technical result is achieved by the fact that the device for water purification by slow filtration, consisting of a housing and a tank with a filter load installed in it, a settling tank associated with means of organizing the input stream, and a reservoir for collecting purified water, according to a utility model, a settling tank contains two electrodes and two solenoid valves, one of which is connected to the control relay, and the other to the time relay, and also the sediment removal means with the electromagnetic valve are controlled m timer, a reservoir for collecting purified water comprises one electrode, wherein the electrodes and the solenoid valves through electrical network connected to the control switch, wherein all the above elements are electrically connected to the low voltage power source.

Supplementing the device with a low-voltage electrical circuit with a minimum set of electrical elements allows you to automate the process of slow filtering that occurs in the filtering device.

The utility model is illustrated in the drawing, which shows a block diagram of a device for water purification.

The device comprises a cover 1, a housing 2, in which the tanks are placed: a settling tank 3 with means for organizing the input stream 4 of filtered water; a reservoir with a filter load 5 into which a filter load 6 is placed with bulk material, for example, coarse sand or activated carbon; and a reservoir for collecting purified water 7. The water treatment device is supplemented by a low-voltage electric network with control and actuating electric elements, which includes the following elements: an upper water level electrode 8, a lower water level electrode 9, while both electrodes 8 and 9 are mounted respectively on different levels in the settling tank 3. The electrodes 8 and 9 are connected to the control relay 10, which supplies an electrical signal to the electromagnetic valve 11 means of organizing the input stream 4. In the upper part of the cut for the collection of purified water 7, an upper level electrode 12 is mounted, which is also connected to the control relay 10. In the lower part of the settling tank 3, a sediment removal means 13 is installed with an electromagnetic valve 14 installed in it, and an electromagnetic valve 15 for supplying settled filter water from the tank 3 to the tank 5. The control signal to the electromagnetic valves 14 and 15 is supplied from the time relay 16. The entire electrical network of the device is connected to a low-voltage power source 17, for example, in the form of a step-down transformer with a voltage rectifier operating from a household network 220 volts, or batteries in the form of batteries or accumulators. For the selection of filtered water, the reservoir for collecting purified water 7 is equipped with a shut-off body 18, for example, in the form of a tap or an electromagnetic valve.

The device operates as follows: When the device is connected to a power source 17, a low-voltage voltage is supplied to the control relay 10, which opens the solenoid valve 11, which is located in the means of organizing the input stream 4, and the settling tank 3 is filled with filtered water, when filled to the upper level of which the electric signal from the electrode 8 is fed to the control relay 10, which closes the electromagnetic valve 11, stopping the flow of filtered water into the settling tank 3. At the same time by closing the valve 11, an electric signal from the control relay 10 is supplied to turn on the time relay 16, the operating time of which is chosen equal to the time of precipitation of solid particles in the filtered water, for example, for filtered water of medium hardness, the response time of the relay 16 is 10 minutes. After a cycle of water sedimentation in the settling tank 3, the time relay 16 is activated, which supplies an electrical signal to the electromagnetic valve 14, opening it. When the valve 14 is opened through the sediment removal means 13, the accumulated sediment is discharged. After the sludge is discharged from the settling tank 3, the electromagnetic valve 14 is closed, then the electromagnetic valve 15 is opened, opening the overflow of settled filtered water into the filter loading tank 5, in which water passes through the filter loading 6, then the purified water enters the tank 7, where its accumulation occurs. After the tank 3 is completely emptied, the electric signal from the electrode 9 is supplied to the control relay 10, which opens the electromagnetic valve 11, filling this tank with filtered water, so the filtering cycle is repeated. If purified water was not used from the purified water collection tank 7, the signal from the electrode 12 blocks the operation of the control relay 10 to supply filtered water to the settling tank 3, i.e. in this case, the electromagnetic valve 11 does not open. The use of the upper level electrode 12 in the tank 7 avoids overfilling of the tank and disruption of the device. Water filtration in the proposed device occurs in a known manner, the so-called slow filtering.

The proposed device is easy to operate, does not require constant monitoring, allows you to constantly have the necessary supply of purified water.
