The alleged invention relates to the field of purification of liquids and gases from suspensions, namely, devices for filtering emulsions and suspensions and can be used in the metallurgical chemical, biochemical, building materials and other industries.

and | western filtering device, where the package contains U-shaped frames, between which 1 / G is placed a zigzag-laid filter material, and the filtering device is made in the form of tapes located on opposite sides of the frames. Such a bag can be used to filter suspensions, emulsions, aerosols. However, during the filtration process, the zigzag-shaped filter material relatively quickly fails, since the pores are quickly clogged, and although the total working time between regenerations of this device is higher than the previous one, its performance remains insufficient.

Another filtering device comprises a housing with nozzles for supplying initial and removal of filtered material, bundles of filtered fibers fixed in the holder and the holder is made in the form of a tubular cage with conical extensions above and below, mounted on the filter partition and equipped with axial axial axial moving one against the other by spacer cones located in the conical extensions of the cage, the fiber bundles having a length exceeding the height of the cage, their upper ends hang nale- Revesz below the upper end of the cage,

Such a filtering device provides a high filtration fineness, since the capillaries formed in the bundle between the strands pressed against each other are very small: they make up about 1/10 of the diameter of the elementary fiber (filament). Consequently, particles smaller than 1/10 of the diameter of the thread can penetrate the capillaries along with the filtered material. In addition, such a filter can be used to separate emulsions, as well as to raise the liquid wetting the material of the threads to a certain height.

The disadvantage of this filtering device is its low productivity; defined by the cross-sectional surface of the fibers clamped in a bundle.

The aim of the invention is to increase productivity while expanding the scope.

An increase in the productivity of the filtering device is achieved by the fact that the proposed design makes it possible to increase the height of the filtering element unlimitedly, which allows without significantly increasing the dimensions of the filtering element to increase the filtration area by at least several times. In addition, the filtration surface is doubled due to the fact that both ends of the beam are used to receive the filtered liquid.

A decrease in filter resistance is achieved by compressing continuous fibers from the ends. As a result, in the center of the fiber, the bundle fibers are swollen and bent along certain arcs, diverging from each other, increasing the diameter of the capillary holes.

The expansion of the field of application was achieved due to the fact that the proposed design is equally applicable for filtering dusty gases, suspensions, emulsions, and even as a membrane for desalination of water.

In FIG. 1 shows a General view of the device in section; in Fig.2 is a plan view of the device; in Fig.3 - axonometric J-shaped clip.

The design of the filtering device includes a housing 1, a nozzle for supplying the filtered material 2, a.-Shaped clip 3 installed in the cavity of the housing, an LZ-shaped clip 4 made in the form of a plastic. equipped with a vertical groove 6, and also through horizontal openings 7, plates 5 mounted with the possibility of vertical movement with screws 7 and equipped with coaxial horizontal through openings 9 of the openings of the cartridge and the vertical wall-shaped cartridge, the filter material 8 in the form of parallel stacked continuous fibers, a locking plate 10, a branch pipe of the filtered material 11, side walls 12, a pipe outlet of the filtrate 13, a cover 14 mounted to seal the body cavity.

The filter device operates as follows. Filtered material in the housing 1 enters through the supply pipe of the filtered material 2, fills the space between the housing, the J-shaped clip 3 and mounted on it with the possibility of movement of the Z-shaped clip 4, in the vertical grooves 6 of which are mounted plates 5, equipped with horizontal

through openings 9 in which the filter material 8 is placed in the form of parallel-laid continuous fibers, between which there are capillaries. Passage through capillaries the filtered material loses suspended particles whose size exceeds capillary channels. Passing into the gap between the 3-shaped clip, the -shaped clip, as well as the closing plate 10 and the side walls 12, the filtered material is discharged out through the branch pipe of the filtered material 11. The collected filtrate through the nozzle 13 is periodically discharged to the outside. In order to regenerate the filtering material, the plates 5 are moved alternately or simultaneously with the help of screws 7, which helps to relax the clamping of continuous fibers between themselves and, consequently, increase the size of the capillaries. Continuous fibers (filaments) of the filter material are loosened together, washed with clean water, a solvent, or purged with compressed air. The cover 14 is tightly pressed to prevent overfilling from the cavity of the filtered material or leakage of the regenerating material.

A filter device can be used to fine filter both liquids and gases. Depending on the diameter of the continuous fibers used as filter material, the fineness of the filtration, i.e. the value of the retained solids. The filtration of emulsions is based on the wettability of the filtered components of the material continuous

fibers. If any component wets the continuous fibers of the filter material, it will move along the fiber bundle in a capillary manner between the fibers. If the component does not wet the fibers of the filter material, it will be expelled from the capillaries. Due to this effect, it is possible to separate multicomponent filterable suspensions, for example, water-oil, etc.
