Description

This utility model relates to a means of preparing water for a pool, namely to a single means of filtering and heating water.

It is known from the prior art that, as a rule, a pool water filtration system consists of a filter unit designed for mechanical purification of water. In such an installation, specially sifted quartz sand with certain granule sizes is usually used as a filtering element, and such installations are usually equipped with a mode switching valve and a pressure gauge to indicate the pressure in the system.

The filtration system is the main unit of equipment designed for water purification in any modern pool. Thanks to filtration, the pool water remains clean and transparent for a long time. Filler in the filter is cleaned by backwashing. The pump draws in water from the pool through the intakes, then the stream supplied by the pump enters the filter unit, where the sand traps microscopic particles, and as a result, clear, clear water flows back into the pool.

At the same time, in addition to water purity, the most important task for ensuring comfort when swimming in the pool is to maintain the temperature of the water in the pool at the right level. This task is usually handled by pool heat exchangers mounted as a separate element at a distance from the filter element in the pipeline of the water treatment system. The design of the pool heat exchanger is a flask, in the middle of which there is a coil. The coolant moves along the coil, the role of which is hot water coming from the heating circuit. In this case, the coil itself is washed with water from the pool to be heated.

Hot water from the general heating circuit enters the coil through a circulation pump controlled by an electromagnetic valve. The capacity of the heat exchanger is selected taking into account such a parameter as the volume of water in the pool.

A solution similar to the above is disclosed, for example, in document RU 108445 U1 (Kozhevnikov Alexander Borisovich and others), publ. 09/20/2011 (D1).

The above solution D1 was chosen as the closest analogue for the claimed utility model.

The disadvantages of this organization of the process of filtering and heating water for the pool are the difficulty of mounting and dismounting the elements of filtering and heating, the inaccessibility of the elements when necessary for maintenance, possible leaks at the points of connection of the heat exchanger, which in turn leads to reduced efficiency of water treatment for the pool.

The task to which the claimed utility model is directed is to overcome the above disadvantages of solutions known from the prior art.

The technical result, the claimed utility model is aimed at, is to increase the efficiency of water treatment for the pool by providing filtration while heating the pool water in a single water treatment building.

The technical result of the claimed utility model is achieved thanks to the fact that a coil containing an inlet and outlet for a heat carrier is installed in the filter capacity of the claimed device filled with quartz sand, where the coil is made with the possibility of passing heat carrier through it and heat transfer through its surface to the treated water to be delivered to the pool

A brief description of the drawings.

FIG. 1 is a general view of the claimed device.

FIG. 2 - a General view of the water treatment system, which includes the claimed filtering device with heating.

Further, for a more accurate understanding, the principle of operation of the claimed device is described with reference to the position of the drawings.

In FIG. 1 and 2 of the drawings indicate the following positions:

1 - pressure gauge;

2 - vent valve;

3 - the upper part of the filter;

4 - pipe;

5 - input coil;

6 - coil;

7 - valve;

8 - slotted separator;

9 - quartz sand;

10 - separator;

11 - output of purified water;

12 - water intake device;

13 - pump;

14 - a filtering device with heated water;

15 - pool.

The claimed heating device with water filtration works as follows.

Water flows from the pool to the inlet of the valve 7, passes into the upper part 3 of the filter through the separator 10 and is cleaned through quartz sand 9 loaded into the filter.

At the same time, the process of heating the water through the area of the coil 6 takes place, in the lower part the water is collected through the slit separator 8, and then, having already been purified, the water is discharged through the outlet 11 by means of a multi-way valve.

In the claimed device, the pressure gauge 1 serves as a system for monitoring the contamination of the filter. In turn, valve 2 serves to vent air. The coolant passes through the inlet 5 of the heat transfer coil to meet the flow of purified pool water, through the passage of the coolant, the process of heat transfer through the surface of the coil takes place, then the coolant is discharged through the pipe 4.

As regards the general principle of operation of the pool water treatment system, including the device of the present utility model shown in FIG. 2, then it is as follows.

Water from the pool 15 passes through the intake device (for example, a skimmer) 12 and is pumped by the pump 13 towards the claimed device 14, in which it is cleaned and heated. Next, the water enters the pool 15.

Moreover, the filter capacity of the housing of the claimed device has a main indicator - the diameter in the range from 350 mm to 950 mm.

The housing material of the claimed device is made of polypropylene or polyester / fiberglass.

The filling of quartz sand in the claimed device can be carried out in such a way that the control valve can be located in the lateral or upper connection to the housing of the claimed device.

The control valve performs the function of adjusting the pool water purification system, depending on the need for filtering, circulation, filter cleaning and draining the pool water. During filtration, water from the pump passes through the sand from top to bottom and returns to the pool. When washing the filter, the water from the pump passes through the sand from the bottom up, and together with the particles of impurities through the drain pipe is discharged into the sewer. When rinsing is carried out, the water from the pump passes through the sand from top to bottom (as during filtration) and is drained through the drain pipe to the sewer to drain contaminated water remaining in the pipes.

The above coil can be mounted in the vertical side surface of the filter capacity of the housing of the claimed device.

The power of the specified heat transfer coil is selected depending on the diameter of the filter capacity of the housing of the claimed device in the range from 28 kW to 75 kW.

In the claimed device, quartz sand with a particle size of 0.5-1.0 mm is used.

During operation of the claimed device, quartz sand is washed, which leads to periodic simultaneous cleaning of the heat exchange surface.

It should also be borne in mind that the installation scheme of the heat exchange coil allows the coil to be removed for preventive maintenance, such as, for example, removing salts, scale and other contaminants from the outer heat exchange surface of the coil and the inner surface in contact with the coolant.

It should be noted that the combination of two elements, namely the filtration and heating elements in a single housing, simplifies the installation scheme and reduces the number of pipelines and also eliminates the contact of plastic pipelines with the coolant, which in turn significantly increases the efficiency of water treatment for the pool

In addition, it should be understood that the use of integrated filtration and heating equipment in one housing is more economical than the purchase of separate sets of filtration and heating equipment, since in this case it will require the purchase of additional pipeline elements and additional costs associated with the labor-intensive and time-consuming installation of this equipment.
