Abstract

The invention relates to filtering technology, in particular to filtering using optics to visually monitor the purity of the analyzed liquid when flushing hydraulic systems. The invention makes it possible to increase the accuracy of observation and expand the range of the temperature difference between the analyzed liquid and the environment, eliminate the fogging of the protective glass, and also ensure the possibility of the retention of para- and ferromagnetic particles when flushing hydraulic systems. The filter housing is connected to a coolant reservoir, and the reservoir is connected to two uneven channels with a cavity formed between the lens and the protective glass. 1 il.

the focal length from the filter package 5, which is a frame 6 with a magnetized cable network 7. The filter bag 5 is connected to the handle) 8, with which you can change its position (turn to 180). Between the lens 4 and the filter package 5 there is a fixed glass 9, which protects the objective lens from contact with the analyzed liquid. Between the lens A and the protective glass 9 there is a cavity A that is volume-variable and communicates with the reservoir 3 through two uneven channels 10. In the upper part of the housing 2 there is a fitting 11 for injecting the analyzed liquid and a fitting 12 for supplying compressed air to the grid filter package. Above the filter package 5, light sources 13 are mounted. Under the frame 6 of the filter package 5, a funnel 14 is installed for draining filter

The optical filter works as follows.

Through a cooling fluid with optical properties (for example, distilled water), it is pumped into reservoir 3 and, according to the principle of communicating xc vessels, through two uneven channels 10 enters cavity A. When the objective A is focused, the level of liquid in reservoir 3 changes accordingly. The cooling liquid serves to remove the heat given off by the analyzed liquid when passing through the filter. The cooling liquid washes the protective glass 9, excluding its fogging. In order to increase the heat transfer surface of the tank 3, it is compressed with fins.

The liquid entering the liquid through the fitting 11 is passed through the filter 5, which is then in the initial (working) position. 11l of the best visual observation of the mesh 7 of the filter cartridge 5 in the housing 2 are mounted sources of snow 13. Using the handle 8, the filter tube 5 is removed, if necessary, by 90 from the initial position - the liquid passes to the passage and the dryness of the filter package starts to be washed from the soil particles. After turning the filter package 5 to 180, it is additionally cleaned from non-magnetic particles.

Feed is analyzed. the liquid and i filter is terminated. The final cleaning of the screen 7 of the filter bag 5 from non-particle particles is carried out with compressed air supplied through the chip 12. To clean the screen 7 from para- and ferromagnetic particles, the filter bag 5 is removed from the filter housing 2. For this, the funnel 14 is retracted using a flywheel 15. Replacing the grid 7, the filter bag 5 is put in place, securing it with the flywheel 15.

The optical filter is relatively cheap to manufacture, simple and easy to operate. It allows monitoring the purity of the fluid without interrupting the process of hydraulic and fuel systems and can be connected to any industrial stand.
