Description

The invention relates to filtration, namely liquid filters, and can be used, for example, for the treatment of natural and waste water.

A filter for cleaning fluid is known, including a perforated contact drum equipped with fibrous filtering material, a device for supplying and discharging a source and filtered fluid 1.

The disadvantage of the filter is the low cleaning efficiency of the liquid due to the fact that the pore sizes of the filter material are not adjustable.

The closest to the proposed in essence and the achieved effect is a device for cleaning fluid, comprising a housing with inlet and outlet connections, inside of which a filtering element in the form of a truncated cone with fibrous filtering material is located on its outer part, on which the presser is placed. a cone, fitted from the inside with a similar filtering material, and an actuator extending the cones, made in the form of an electric motor with a screw transmission, providing a vertex ikalnoe displacement cone 2.

Although the filter provides high-quality cleaning of the fluid and effective regeneration of the filtering element, however, the presence of an additional piece of equipment for the electric motor with a transfer for the separation of the cones significantly increases the energy consumption for cleaning the fluid and makes it dependent on the source of electricity and complicates the device. At the same time, the screw of the steam, working under direct contact under the conditions of the often abrasive and aggressive environment, is subject to rapid wear and corrosion and is out of service, which requires stopping the equipment and repairing it.

The aim of the invention is to reduce energy consumption and simplify the design by using an overpressure of the fluid being cleaned.

This goal is achieved by the fact that in a device for cleaning a fluid, comprising a housing with inlet and outlet nozzles, inside of which there is a filter element in the form of a truncated cone with fibrous filtering material on its outer part, on which a pressure cone is placed with movement parts similar to the filtering material, and the separation of the cones, the latter is made in the form of two sealed cones corrugated on both sides of the upper base of the moving cone cavities connected through shut-off valves to the raw liquid supply line and to the atmosphere.

FIG. 1 shows the device at the time of filtration, the general view; in fig. 2 - the same.

at the time of regeneration of the filter element.

The device comprises a housing 1 with nozzles 2 and 3 for input and output of a liquid, a filter element 4 in the form of truncated cones 5 and 6, and a drive 7 for extending the cones.

In the lower part of the housing 1, a cone 5 is reinforced with a lateral permeable surface with fibrous filter material 8 fixed on it. In the upper part of the housing 1, the drive 7 is mounted with a vertical movement by a drive 7 with a pressure cone 6, the inner surface of which is also covered with fibrous filter material 8.

5 Drive 7 is designed as fortified

on both sides of the upper base 9 of the cone 6 of two sealed corrugated cavities 10 and 11. The walls of these cavities can be steel, as well as from elastic materials, such as rubber. 0 Cavity 10 is connected to pipeline 12.

supplying the crude liquid through the pipeline 13, equipped with a shut-off valve 14, and with the atmosphere through the pipe 15, equipped with a valve 16.

The cavity 11 communicates with the pipe 5 12 through a pipe 17 placed inside the perforated pipe 18. The pipe 17 is provided with a shut-off valve 19. The cavity

11 communicates with the atmosphere through the pipe 20, equipped with a valve 21. The pipeline

12 is equipped with a shut-off valve 22. In the lower part of the housing 1 a drain pipe 23 is installed.

The device works as follows.

When filtering the crude liquid

enters the pipe 2, passes through the filtering material 8 of the cones 5 and 6, the perforated pipe 18, the pipe 3 and is sent to the consumer.

After filling the pores of the filter material 8, the filter is regenerated. To do this, close the valves 22 and 21 and open the valve 19. The initial liquid under pressure through the pipeline 17 enters the corrugated cavity 11, which lengthens and ensures that the truncated cone 6 rises until it stops. When this occurs, the fibers of the filter material 8 are agglomerated, which contributes to its good loosening and shaking of the soil retained on the fibers, 5a, which creates favorable conditions for the regeneration of the device.

Then the valve 22 is opened and the liquid enters the upper part of the housing 1, passes through the side wall and washes away the sediment from the filter material 8, after which it flows down into the lower part of the housing 1.

5 At the same time, the rinsing water through the nozzle 3, the perforated pipe 18 is fed into the cavity of the housing 5, passes through its side wall, the filtered material 8,

washes away sediment from it and flows to the bottom of housing 1, where it is discharged through pipe 23. After regeneration of filter element 4, the device is switched to filtering mode. For this, valves 16 and 19 are closed and valves 14 and 21 are opened. The initial fluid through conduit 13 is supplied under excessive pressure to corrugated cavity 10, as a result of which the latter lengthens and moves cone 6 downward, ensuring that it is pressed to cone 5. In this case 11 is compressed, and the liquid is removed from it through the pipe 21. Next, the valve 22 is opened and filtered. Since fluid overpressure is substantial and fluctuates within

//

1.5-10 atm, then you can create almost any required effort to expand the cones. At the same time, the expansion force can be adjusted by the diameter of the cavities.

The invention makes it possible to reduce the cost of electricity for cleaning the liquid by up to 15-20% and reduce the cost of the filter 1.2-1.3 times by simplifying the design by eliminating an additional piece of equipment — a drive with a pressure cone movement transmission system — and using the overpressure of the original fluid. The dependence of the operation of the device on the source of electrical energy is also eliminated, and the reliability in operation increases, since there are no rubbing knots.
