Description

(Reg. 1

The invention relates to filter elements for the cleaning of gases and liquids from mechanical impurities and can be used in the mining, chemical and other industries.

The purpose of the invention is to increase the oppressive ability and decrease the hydraulic resistance of the filter element, as well as to reduce its overall dimensions.

tia fig. 1 shows the filter element, a longitudinal section; in fig. 2 - arrangement of chips in the layers; in fig. 3- forming chips into a spiral; in fig. 4 - placement in the chip of the swallow rope; in fig. 5 is a section A-A in FIG. 3

The filter element includes a housing 1 with a lid 2, an inlet 3 and an outlet 4 nozzles, a filter element in the form of layers 5,6 and 7 of compressed ferrous and non-ferrous metal chips. Segments 8 of one layer tightly (without a gap along the generatrix) are adjacent to one another and perpendicular to the segments of chip 9, which are perpendicular to the axis of the filter. The chips 10 are folded into spirals, which is located in a plane perpendicular to the axis of the filter, with the turns of one spiral nested in the hollows of the other. Segments 8, 9, and 10 may alternate in layers, for example, black-color. The chip segments of the layer 6 form helical through channels parallel to the filter axis and tapering in the direction from the inlet to the outlet nozzle and placed between layers 5 and 7. The absorbing harnes 12 are passed through the channels of the chip 11, which ensure the regeneration of the filter during the analysis of the filter.

The filter element works as follows.

The fuel to be cleaned, oil or air through the opening of the inlet nozzle 3 enters the cavity of the housing 1 and fills the layer 5, b and 7 and, being cleaned, leaves the outlet nozzle.

. The black and color layers were made with a ratio of chip width to its thickness of 3: 1, while chips of the type of small loach corresponded to the requirements of GOST 2787-86. Going beyond the ratio of the chip width to its thickness, equal to 3-7, worsens the pressing conditions and filtering properties, since, for example, it decreases

uniformity of pores in size, as seen when cutting a layer of chips.

The following materials can be used as the material: cast iron (chips are elemental in the form of small chips, pieces, etc.); steel (chips elemental in the form of coils, fine loach, medium loach, large loach, saber-like, etc.); aluminum (chips elemental in the form of turns, fine loach, etc.); nickel, copper, brass ,. bronze (chips elemental in the form of a fine loach, crumbs, etc.); duralumin (chips are elemental in the form of fine crumbs, grains, dust, etc.).

Color shavings, reducing the wrinkling and excessive — deformation of black shavings, which are essentially viscous dampers, increase the filtering properties. In order to increase the absorptive capacity and improve the stability of the filter shape, the layers are equipped with a harness made, for example, of fibrous or porous material. In this way a multi-layer filter can be obtained. The introduction of one chip into another canal leads to a similar result, while multi-layer chips can be made of different metals. The presence of a harness also facilitates and accelerates the regeneration (cleaning) of the element.

The through vertical spiral-shaped channels tapering to the outlet nozzle make it possible to most fully use their surface as a filtering one and increase the efficiency of the filter element due to vortex (wave) motion of the working medium in the channels.

The raw material base for the manufacture of this filter element is in fact enormous, since the enterprises have a metal shavings mass during machining of the machined parts more than 10% of the mass of these parts, in addition, the cost of such a filter is small, and it is compact and durable the service is not difficult; it provides for a wide unification of filters and reduction of their standard sizes.
