Description

The utility model relates to the field of liquid filtration, and in particular to (filter elements), and can be used in devices for filtering liquids and in installations for cleaning liquid media in various industries.

Known drainage distribution device according to the author's certificate of the USSR No. 1681889, class. B01D 24/38, 1991, containing a collector and pipes connected to it with plugs at the ends, with holes along the generatrix and a slot element attached to the pipes above the holes, the holes are made in the form of truncated cones mated with large bases, and the slots in the element are made in the form of blinds.

The disadvantage of this device is the complexity of its design and manufacturing technology by making holes in the form of truncated cones and using a slit element in the form of blinds, which does not provide sufficient cleaning for the liquid and contributes to increased entrainment of the filling (filter material during filter regeneration).

Known drainage distribution device according to the patent of the Russian Federation No. 2367499, class. B01D 24/38, 2009, containing a collector, pipes connected to it with holes and plugs at the ends and hermetically connected to each of the pipes above the holes of a groove with slots made parallel to the pipe, the groove consists of ribs to which rows of wire are attached of triangular section, installed with a gap, the slots forming due to the gap have an expanding profile, the groove in the cross section is made in the form of a circle segment, the ribs of the groove are longitudinal and the rows of wire are attached transversely.

The disadvantage of this device is the complexity of its design, insufficient rigidity and strength of the tube-beam, increased ablation of the filling filter material during the regeneration of the filters of the device.

Known drainage distribution device according to the patent of the Russian Federation No. 2375098, B01D 24/38, 2009, adopted by the applicant for the prototype. It contains perforated pipes and slit elements located on them, made in the form of cylinders, slot elements are located on the pipes at a distance from each other, perforation on the pipes is made in areas located in the places where the slot elements are installed, and the slot elements consist of ribs rigidly connected with rows of triangular-section wire installed with a gap between adjacent rows of wire, the resulting gap ensures the presence of slots expanding from the surface of the slot element to its center.

The disadvantage of this device is the complexity of the design, insufficient rigidity and strength of the tube-beam, excessive metal consumption.

The technical task of the utility model is to simplify the design of the drainage distribution device and increase the rigidity and strength of the collector tube-beam while maintaining a stable slotted channel to prevent entrainment of filter material from the filter tank.

The problem is solved in that in the proposed solution, each tube-beam of the collector in cross section is made in the form of a stylized n-tooth gear, forming troughs and ridges, holes are made in troughs, and rows of wire wound across the wire are wound on each tube-beam and rigidly placed on the ridges with a step that defines the gap for the passage of fluid and the retention of the filter material fraction, each tube-beam with the rows of wire wound across it to form a filter element, and each perforated hole cell and across the series wound wire forming an additional channel for fluid flow.

In addition, the rows of wire wound across the wire are rigidly fixed to the ridges by resistance welding.

In addition, in cross section, the collector tube-beam is made of at least two depressions.

figure 2 shows a fragment of the pipe-beam of the collector assembly, side view;

figure 3-section aa in figure 1, a side view of the profiled tube-beam.

A drainage-distributing device 1 is installed in the lower part of the filter 2 and contains a central outlet 3 to which two radial and oppositely directed collectors 4 and 5 are connected. To each collector 4 and 5, pipe-beams are connected 6. Parallel-tube 6 are directed in opposite directions from the collectors 4 and 5, and their ends are closed with plugs 7. On the lateral surface of each tube-beam 6, holes 8 are made for the passage of the filtered fluid, and rows of wire 9 are wound across each tube-beam 6.

Each tube-beam 6 of the collectors 4 and 5 in cross section is made in the form of an n-tooth gear, forming troughs 10 and ridges 11. Holes 8 for passing filtered fluid are made in troughs 10, and the rows of wire 9 wound across are wound on each tube-beam and rigidly placed on the ridges 11 with a step that defines the gap to hold the selected fraction of filter material 12. For this, each tube-beam 6 with the rows of wire 9 wound across it form a filter element, and each perforated cavity 10 is wound transverse rows of wire 9 form an additional passage 13 for fluid flow, which has a gutter shape.

The cross-sectional profile of the pipe-beam 6 of the collectors 4 and 5 is made by running, and the rows of wire 9 wound across the wires are rigidly fixed to the ridges 11 by resistance welding. The step of winding the wire 9 is made depending on the size of the fraction of the filling filter material 12.

In the cross section of the pipe-beam 6 can be made of at least two ridges 11 and two depressions 10, both each of the entire collector 4 or 5, or separately taken depending on the degree of purification of the liquid. The optimal number of depressions 10 and ridges 11 choose 4, 6 or 8.

Drainage distribution device operates as follows.

The liquid to be cleaned enters the upper part of the filter 2 and passes through a layer of filled filter material 12, in which it is cleaned of large impurities. Sinking to the bottom of the filter 2, the liquid reaches the tube-rays 6 and passes through the slots in the rows of wire 9 wound around the tube-rays 6 into the holes 8 for passing the filtered fluid and through the beam-tubes 6 enters the collectors 4 and 5, of which then - to the central branch 3. From the central branch 3 the purified liquid leaves, which then returns to the technological cycle. After passing a certain number of cleaning cycles, filter 2 is regenerated by supplying fluid through a central outlet 3.

Due to the implementation of the pipe-beam 6 in the form of an n-gear gear and wound with a certain pitch across the rows of wire 9, defining between the rows a gap designed to hold the selected size fraction of the filling filter material, a stable prevention of entrainment of the filter material is ensured.

The use of the proposed technical solution allowed us to simplify the design of the drainage distribution device, to increase the rigidity and strength of the pipe-beam of the collector by making it in the form of an n-tooth gear with hollows and ridges, increasing its rigidity and strength, and in conjunction with wound with a certain step across in rows of wire, forming an additional channel not only to increase the degree of purification of the liquid, but also to maintain a stable slotted drip to prevent entrainment of filter material and out of the filter tank.
