(54) FILTER FOR FLUID CLEANING

t

The invention relates to sanitary engineering and can be used for wastewater treatment.

A filter for cleaning liquids is known, comprising a housing, inlet and outlet pipes, a package of filter plates with through holes made in the form of fixed and movable sections, the plates of the movable section being hinged on a rack, one end of which is rotatably fixed l.

The disadvantage of this filter is low productivity, due to the insufficiently effective filtering area, since the width of the gaps between the holes of the filter plates must be at least the width of the holes, since the holes overlap with adjacent jo plates. This circumstance also causes an increase in the size of the filter, which corresponds to the fact that it is necessary to remove the filter.

The purpose of the invention is to increase the filter performance.

This is achieved by the fact that the filter plates are made of variable cross section and are installed with the possibility of their rotation.

FIG. 1 shows the filter, a general view; FIG. 2 shows a packet of filter plates (the position of the plates during filtration); in fig. 3 - a package of filter plates (the position of the plates during regeneration).

The filter includes a housing 1 in which a package of filter plates 2 is placed. Filter plates by means of balls 3 are fixed on frame 4 and connected to each other by means of rod 5 and hinges 6. Rod 5 by means of plate 7, hinge 8 is connected to thrust Q, for which in case 1 there is a sealing slot. T ha 9 by means of a spring 10 is connected with electromagnets 11, 12, mounted on a support gate 13, on which a stop 14 is mounted, by means of which

The size of the filtering slit and the stop 15 for installing the filter for regeneration is controlled.

On-housing 1 is placed a pipe 16 for supplying the source fluid to the filtration and a pipe 17 for draining the purified liquid. On the base plate 13 is installed, the adjustment scale 18,

The filter works as follows. When filtering, the initial liquid through the pipe 16 enters the package of filter plates 2. At the same time, the filter plates 2 through plate 7, hinge 8, ti g 9 with spring U ,. electromagnets 11, 12 and the stop 14, Novoryuti in a position in which the gap between the adjacent plates at the output reach the desired value. As the filter plates are of variable cross section, the gaps between the plates vary in height of the filter bag from the maximum value at the inlet to the desired value at the output of the filter bag.

The passage of the filter bag contained in the source liquid solid inclusions is delayed. in the gaps between the plates. Moreover, the caupality of solid inclusions retained in the filter package is reduced along the height of the filter package in accordance with the change in the size of the gap between the plates.

The filtered liquid is discharged through the pipe 17.

After filling the gaps between the plates with solid inclusions, the filter is regenerated. For regeneration, the package of filter plates 2 by means of plates 7, ti gi 9, electro4

the magnets 11, 12 and the anvil 15 rotates to a position where the gaps between the plates reach a maximum value. Filter regeneration is carried out

filtered liquid reverse current. The filtered liquid through the pipe 17 is fed into the filter housing, passes through the increased gaps and through the pipe 16 will mow the detainees

t & hard inclusions from the filter.

The flushing time depends on the characteristics of the contaminants, the size of the initial gaps and the intensity of the flushing.

Switching pipelines when re-

water filter from the filtration mode to the regeneration mode is produced by one of the known methods. . .
