Description

(54) FRAMEWORK FILTER OF CONTINUOUS ACTION

The invention relates to the field of filtration, mainly to the field of purification from dispersed particles, and can be used in the chemical and other industries.

A filter is known, comprising a housing, a stack of filter plates, a feeding device with a reciprocating drive, spools for removing sediment, a crankshaft, an electric motor with a gearbox 1.

This construction is very complicated and inconvenient in the process of using the filter. Filter plates are cleaned with compressed air; therefore, a compressor is necessary for normal filter operation, which increases the cost of fluid treatment. A large number of simultaneously involved in the work of mechanisms reduces the reliability of the filter.

Closest to the invention, to the technical essence and the achieved result, is a filter comprising a vertical cylindrical body with water inlet and outlet connections, filtering frames located inside the body 2.

The disadvantage of this filter is that for washing it is necessary to stop and empty the filter. During regeneration, the intensity of flushing of contaminants in the areas of the filtering frames adjacent to the nozzles is higher than on the rest of the filtering surface, i.e. reduced regeneration efficiency.

The aim of the invention is to increase the efficiency of regeneration.

The goal is achieved by the fact that the filter containing a vertical cylindrical body with

15 . water inlets and outlets, filtering frames, placed. inside the case, provided with a transverse impermeable partition with radial constrictions of the crevices, and

20 central column with U-shaped guide rods fixed on it, in which filtering frames are placed.

The filter can be provided with a deep radial partition placed between the inner surface of the shell and the upper part of the column.

Figure 1 presents a General view of the filter; FIG. 2 is a general view of the transverse river partition and central

columns; FIG. 3 is a schematic diagram of: degrading filter frames; FIG. 4 is a diagram of the filtering frame (side view) during operation; figure 5 - the same, during the flushing on figb the same during the shutdown of the frame from work; Fig, 7 - a general view of the filter frame.

The filter contains a vertical-facing cylindrical chassis 1, divided by a transverse impermeable partition 2 with radial sulsivnye slits. Know the upper working and lower washing chambers .; Inside the axis of the cylindrical housing there is a column 4 “At the same time, the surface will be znat. corps and on, the central column 4 are longitudinally fixed. 5 P-shaped sections The number of rods on the inner surface of the hull and on the column is the same as the location of the pockets. radius against each other.

In the grooves formed by the recesses of the P-shaped f-section, rigid frames 6 are inserted with an optical material.1 7 5 Upper working. divided by a deaf radial septum 8. In the upper working chamber, the initial water is supplied through the pipe 9, and the filtrate is discharged from the top chamber through the pipe 10.

The filter works as follows

The initial water supply is fed under pressure through the pipe 9 into the upper working chamber and nachtlna.

.EODI and filtrate requirements. The filtrate is taken out through the pipe 10. When the frames are soiled, they are flushed, which is carried out as follows.

The filter is not disabled. The electric motor 16 of the first frame is turned on and rotates the spindle 17, which, being screwed into the thread of the coupling 15, enters the pro / tal hole of the vertical post 14 and causes the frame 6 to move vertically.
