Abstract

The invention relates to screen filters and allows an increase in the degree of condensation and productivity. The device comprises a housing, a conical net cloth with longitudinal slits, a drainage path in the form of hollow blades and a branch pipe, and a cleaning device in the form of scrapers. The slits of the canvas are provided with plates fixed on the hinges. The plates are provided with torsion springs and heel contacting with the scraper. When the blade rotates, the scrapers contact the fifth and turn the plates, opening a slit, through which soils fall into the hollow blades and the nozzle. When the blade is further rotated, the plate is removed from the scraper and the plate closes the slot under the action of a spring. 4 il. (L

Description

The invention relates to screen filters, can be used to purify water and thicken mixtures in industrial and agricultural production, and is an improvement to the device according to the author. No. 1291181.

A piped filtering device is known, which contains a conical net cloth, a cleaning, a device and a drain path.

 The drawback of the device is the low efficiency of its operation due to the clogging of the mesh with sediment, which limits its use.

Closest to the proposed technical solution is a piping filter device,

containing a cone-shaped mesh cloth installed in the housing that can be rotated, made with longitudinal cracks, a drainage path made in the form of hollow mouths fortified outside the mesh cloth opposite the cracks, and a cleaning device in the form of scrapers mounted inside the mesh cloth and fixedly attached to the body.

The known device improves the reliability of operation due to the use of scrapers to remove sediment from the surface of the mesh fabric, however, a significant amount of source water is uselessly released into the drainage path, the net of the gap in the net5

The chat canvas is all the time open for its unhindered entrance. It does not provide the required thickening of the precipitate.

The purpose of the invention is to increase the degree of condensation and productivity ..

The goal is achieved by the fact that in a pipe filtering device containing a conical net mounted in a housing rotatably, made with longitudinal slots, drainage path made in the form of hollow blades fixed outside the mesh cloth opposite the slots, and a cleaning device in the form of scrapers installed inside the mesh fabric and fixed to the body; the slots of the mesh fabric are provided with plates hinged by a longitudinal edge to the longitudinal the edge of the slots, fitted with torsion springs mounted on hinges, and the fifth in contact with the scrapers.

In the filtering technique, scrapers are used to remove contaminants from the surface of filter elements, however, in the inventive device, the plates are provided with gaps, the hinged attachment of plates with the longitudinal edge to the longitudinal edges of the slots, and torsion springs mounted on the plates; contact with the scrapers increase the efficiency of the debris disposal by opening the slots only at the moment of approaching the scrapers to the slots, which leads to a concentration of ka and reduces the flow of source water to the conclusion of this sediment.

FIG. 1 shows the scheme of the claimed device, general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 shows the node I in FIG. 2; FIG. 4 — node II in FIG. 2

The device (Figs. 1-4) comprises a housing 1, a tapered mesh cloth 2 with longitudinal peaks 3, a drainage path made in the form of hollow blades 4 and a nozzle 5 and, a cleaning device in the form of scrapers 6. The mesh cloth 2 is installed in housing 1 rotatably. The base of the blade 2 is in contact with the ring 7 attached to the housing 1,

With their open parts, the left blades 4 are attached to the edges of the slots 3 and connected to the nozzle 5 via seals 8. The scrapers 6 are attached at one end to the body 1 and the other to the cylindrical insert 9. Shells 3 of the blade 2 are provided with plates 10 mounted on hinges 11 longitudinal edge to the longitudinal edge of the slots. The plates 10 are provided with torsion springs 12 mounted on hinges 11. At the location of the hinge 11, a pin 13 is rigidly attached to each plate in the form of a short rod, in contact with the scrapers 6. The housing 1 is embedded in the pipeline 14.

The device works as follows.

The contaminated liquid enters the tapered mesh fabric 2 from the inside to the outside and, after filtering through it, leaves contamination on it. The pressure flow in the pipe 14 rotates the blades 4, and together with them the mesh fabric 2. The scrapers 6 reduce contamination from the surface of the conical mesh cloth 2 and bring them to slots 3. The scrapers 6 come in contact with the fifth 13 and turn The plates 10, overcoming the resistance of the spring 12 and the opening of the slit 3, through which contaminants fall into the hollow blades 4, from where the spout 5 and the housings and housings go to the outside. Upon further displacement of the scraper 6 relative to the slit 3, the third 13 falls off the scraper, and the spring 12 rotates the plate 10, closing the slit 3.

Claims (1)

The technical and economic efficiency of the proposed device as compared with the known one is to increase the efficiency of land separation by opening the gaps only at the moment of approaching the scrapers to the gaps, which ensures the removal of more condensed sludge and prevents the original liquid from leaking out through the gaps in the mesh fabric. This is made possible by the installation of spring-loaded swivel plates interacting with the scrapers in the slots. This reduces the flow rate of the source water through the collecting path to 30–40%.
