SU568448A1 - Liquid purifying filter - Google Patents

Description

The invention relates to a part of mechanical engineering. The filter is designed to clean liquids in cars and hydraulic systems, where there is a change in fluid flow through the filter, for example in diesel engine fuel systems of a transnort; s funds.

Filters for cleaning liquids are known: - ;, the advantage of fuel in an internal combustion engine, comprising a housing connected to a cup, stirred, in the latter a damper and filtering element, made in the form of a cone-shaped branch with a net mounted to it and fed to it. in a glass with; gap 1.

B: known filters, the cleaning of the liquid is carried out as a result of organized settling of the grid. However, in such filters, with increasing fuel consumption, the cleaning efficiency is drastically reduced due to the reason; and changing the flow rate through the gap. As the fuel flow rate increases, the kinetic energy of the flow disrupts the process of organized sludge under the damper and the fuel is cleaned only by mechanically screening the particles of the shield with a grid.

The aim of the invention is to increase the cleaning efficiency by adjusting the clearance of the gap with a change in the consumption of hardness. it

is achieved in the proposed filter for cleaning the liquid by the fact that in the glass is concentric to the Cone reflector installed with the possibility of moving along the axis of the glass a spring-loaded nozzle.

The drawing shows onymy ;; filter in longitudinal section.

A cup 5 is attached to the body / through the gasket 2 npj: using the Pazhpmno ring 3 and bolts 4. Inside the glass there is a filter element, made in the form of a conical reflector 6 with a grid 7 attached and a threaded plug 8 of Fi; Step1:; s element is installed in glass 5 with a gap and is adjusted to the shell through

5 a distribution washer 9 with holes a. In the middle part, but at the height of the glass, there is a Usoyoka 1tel 10, made with petals //, regularly positioned by the silt

There is a pacifier and a stack} of a stack; a hectare HMS slot, which communicates the cavity of the glass under the filter element with the zone:: sludge at the bottom; asti glass. Ko.ntsy le25 pestkov bent to the inside of the glass, forming a platform for installing the spring 2. H ;. the upper end of the spring is mounted with the possibility of movement along the axis of the glass nozzle 13. Between the inner surface

0 nozzle and base cone reflector:

there is an annular gap r, which communicates the shallowness of the cavity of the glass above and below the filter element.

The filter works as follows.

ZHDkost, for example fuel

in the engine

under davleznutrennego combustion, enters

cavity L mnem through channel d, in the annular; The body /, then, the cut hole in the sawing above the filter element, through the jasop g fills the cavity under the flushing element, and through the slit C - the zone of the bottom of the glass. When moving the tonis through the gap g, the flow rate of the fuel increases. Mechanical particles of soil and water droplets, which have a greater specific weight than fuel, continue to move along the wall of the glass by inertia, reaching the calmer 10, pass through the slot in and fall into the zone of sludge in the bottom of the glass. The output of the cleaned fuel from the filter is made through the central opening b of the damper, the grid 7 and the channel e in the housing. Part of the flow of fuel is filtered through the mesh, mine sludge zone.

When the mode of operation of the engine changes, the speed flow in the gap r changes its value. When the fuel consumption increases from some initial optimal value. The velocity head on the nozzle 13 increases, the forces generated thereby move the nozzle to increase the flow area of the gap, compressing the spring 2. When the fuel consumption decreases to the optimum value of the nozzle under the spring - re-moves in the direction of the clearing of the frontal gap section. In both cases, the flow rate; in the gap, regardless of the fuel consumption, is set optimally: for the filtration process with sludge.

Form y

A filter for cleaning a liquid, preferably fuel, in an internal combustion engine, comprising a housing connected to the glass, placed in the last damper and filtering element, made in the form of a cone reflector with a mesh attached to it and installed in a glass with a gap that differs in that, in order to increase the cleaning efficiency by adjusting the clearance when the flow rate changes, the concentric cone reflector in the glass is installed with the possibility of moving the spring-loaded along the axis of the glass th nozzle.
