Description

DEVICE FOR CLEANING LIQUID MEDIA

The invention relates to devices for filtering liquid media and can be used in various industries where effective cleaning of liquid media from mechanical impurities is required, in particular, in oil cleaning systems of internal combustion engines.

In the proposed utility model, a method of regeneration of filtering elements of a self-cleaning filter is implemented by supplying a reverse fluid flow through the filtering elements with the simultaneous removal of contaminant concentrate.

A device for cleaning liquid 1 is known, which contains a tank for circulating oil connected to the inlet of the main pump, a self-cleaning filter with a channel for continuous drainage of contaminants, a main oil line in communication with the output of the self-cleaning filter, a centrifugal filter with a drive connected to the tank for circulating oil, and auxiliary pump in communication with the inlet of the centrifugal filter.

. The disadvantage of this device is the significant complexity due to the large amount of equipment.

The closest in technical essence to the proposed technical solution is the known liquid purification device 2 used in the lubrication system of an internal combustion engine and containing a tank for circulating oil, a main pump with an inlet connected to the tank, a self-cleaning filter with a continuous contamination drain line, the main oil a line connected to the exit of the self-cleaning filter, a centrifugal filter with a drive, an auxiliary pump with a drive, and a separation unit.

Such a device also has the drawback noted above - the complexity of the design, due to the large number of equipment, in particular pumps.

In addition, the known device has insufficient efficiency of regeneration of filtering elements.

The technical result, which consists in eliminating these drawbacks, is achieved in a device for cleaning liquid media, comprising a pipeline for supplying a liquid to be purified from a liquid source, a pipe for discharging the purified liquid and a channel for discharging the concentrate of contaminants associated with a closed hollow housing in which the filtering elements are secured, fastening and sealing elements, in that it contains a pulsed fluid flow interrupter installed in the contaminant discharge channel.

In this case, a pulsed fluid flow interrupter is located inside or outside the housing.

The specified technical result is also achieved by the fact that the outlet of the purified liquid outlet pipe and the outlet of the contaminant concentrate drain channel are connected to the liquid source, while a closed circulation cycle is provided when filtering the liquid.

The essence of the utility model is illustrated by drawings, where:

FIG. 1 shows an embodiment of the device in which a liquid flow interrupter with a contaminant discharge channel is located inside the device body;

FIG. 2 shows an embodiment of a device in which a liquid flow interrupter with a contaminant discharge channel is located outside the device body;

FIG. 3 and FIG. 4 shows the options for a device with a closed cycle of use and purification of liquids (for example, the channel for the removal of contaminant

closed with the channel for supplying the filtered fluid through the oil pan of the internal combustion engine).

The device (Fig. 1 - Fig. 4) comprises a pipe 1 for supplying a liquid to be cleaned 1, a closed hollow body 2, in which filter elements 3 are located, a pipe 4 for discharging the purified liquid, an impulse interrupter 5 for the liquid flow and a channel 6 for removing the contaminant concentrate.

In FIG. 3 and 4, a source of liquid 7 is indicated.

Fasteners and sealing elements are not shown in the drawings.

The output of the pipeline 1 for supplying the cleaned liquid 1, the input of the pipeline 4 of the outlet of the purified liquid, and the entrance of the channel 6 of the discharge of the concentrate of pollution is connected with a closed zero housing 2.

A pulse interrupter 5 of the fluid flow installed in the channel 6 of the discharge of the concentrate of contaminants, while it can be located both inside the housing 2 (Fig.1, 3), and outside the housing (Fig.2, 4).

For the design options shown in FIG. 3 and FIG. 4 the output of the pipeline 4 of the outlet of the purified liquid and the output of the channel 6 of the discharge of the concentrate of pollution associated with the source of the liquid 7.

The device operates as follows ..

The liquid to be cleaned flows from the source 7 through a pipe 1 to the housing 2 and passes through the filtering elements 3, on which contamination is deposited. The purified liquid from the housing 2 is supplied to the consumer through the pipeline 4.

The direction of fluid flows through pipelines 1 and 4 and channel 6 is shown by arrows, while blackened arrows indicate flows of untreated liquid and contaminants, and non-black arrows indicate a stream of purified liquid.

when the fluid flow changes through the filter elements 3 to the opposite, the impurities are washed off from the filter elements 3 and the contaminant concentrates on a pulse interrupter 5 of the liquid flow, which creates a pulse differential pressure on the filter elements 3, and the contaminant is removed through channel 6. The pulse differential pressure will be cause hydraulic shocks that will generate vibration of the filter elements, which will facilitate the removal by means of hydromechanical shaking of contaminants adhering to the filter uyuschie elements and improve regeneration efficiency.

The amplitude, frequency and shape of the vibration pulse are determined by the design of the pulse flow chopper 5, which can be performed, for example, in the form of a solenoid and controlled by a pulse generator (not shown in the drawings).

In the proposed device, the technical result is achieved both by simplifying the design, and by increasing the efficiency of the regeneration of the filter elements, since the device uses a reverse fluid flow through the filter elements to regenerate them with the discharge of the filtered contaminant concentrate.

At the same time, operating costs are reduced, since the periods of unattended operation of the device can be increased.

Parts and components of the device are made of well-known structural materials (steel, plastic, filter material, etc.).

The device passed the test, showed high reliability and operational efficiency and is in production.
