The invention relates to a technique for the purification of liquids from mechanical impurities, mainly to slot filters, and can be used to clean coolant, liquid petroleum products in automotive and automotive engineering and other industries.

The purpose of the invention is to simplify the design of the filter and its operation by increasing the efficiency of regeneration by reverse flow of fluid.

1The target filter for cleaning the liquids from mechanical impurities consists of a cylindrical body 1, inside which the outer fixed filter sleeve 2 is concentrically located along the axis of the body 1, filtering the two-casing cylinder 3 and filtering the central cup 4; the filtering double-shell cylinder 3 is made with the possibility of axial reciprocating movement with respect to the fixed outer sleeve 2 and the central cup 4.

rigidly interconnected by studs 20, which serve as a means for connecting these elements with the power body 11.

Inside each hollow cylindrical head 9 and 10 of the control, cylindrical walls 21 are made, which 50 are installed on a tight sliding fit with the adjacent walls of the valves 16 and 17. In each cylindrical. the wall 21 is made of the window 22, forming with the flange 23 of the annular cavity 24,

In the inner cavity of the lower cylindrical wall 21, a stand 25 is placed, which, in regeneration mode, closes the opening 19 in the bottom of the working surfaces of the external fixed sleeve 2, the double casing 3 and the central glass 4 that are grooved 6, forming flat ridges 7, In the inner grooves 6 of the outer fixed sleeve of the double cylinder cylinder 3 and the central cup 4 there are made through holes 8, which serve as a means for supplying the cleaned fluid to the gaps 5, as well as for supplying on the opposite side

The dimensions of the gaps 5, forming filtering gaps between the working surfaces of the filtering elements 2-4 facing each other, are set so that they are smaller than the dimensions of the grooves 6 and the holes 8 through them.

Hollow cylindrical control heads, top 9 and bottom 10, are attached to the ends of the cylindrical filtrate body 1, forming with the power organ 11 (for example a hydraulic cylinder) means for regenerating the filter. The upper 9 and lower 10 wellhead heads are almost identical in design. Constructive differences between them are due only to the need to mount the power body 11, i.e. In principle, it is possible to make these cylindrical control heads interchangeable.

The cylindrical heads 9 and 10 of the control have nozzles: the nozzle 12 serves to inject the liquid to be cleaned, the nozzle 13 to remove the cleaned liquid, the nozzle 14 to 30, to inject the washing liquid, and the nozzle 15 to exit the contaminated washing liquid during regeneration slotted filter.

A slit filter for cleaning mechanical fluids from liquids works as follows.

In the filtering mode, the cleaned liquid enters the filter through the nozzle 12, the windows 22 in the lower cylindrical wall 21 and through the holes 18 into the cavity of the cylindrical valve 17. In this position, the annular cavity. 24 of the lower hollow cylindrical head 10 of the control is blocked by the walls of the cylindrical valve 17, so that the cleaned fluid only enters the internal cavity of the double cylinder 3. The passage of the hole 8 in the wall of the double cylinder 3, the cleaned liquid is distributed along the grooves 6. Since the grooves 6 are facing each other working surfaces of the external fixed sleeve 2 and the central cup 4 are axially displaced one relative to another and are located opposite the flat ridges 7, then filter out the liquid c in narrower gaps 5, —again. particles of mechanical charges in the cavities of the grooves 6. The cleaned liquid enters the cavity of the central cup 4 and into the annular volume between the wall of the housing 1 and the external fixed sleeve 2. Lift up, cleaned the fluid enters the nozzle 13, with: its access to the annular cavity 24 of the upper hollow cylindrical head 9 of the control is blocked by walls; engines 17, located in the upper extreme position, fixed by the power body 11..

In the regeneration mode, when it increases, the pressure drop across the filter. E and its capacity decreases below the set limit, the filter works as follows. After the control signal arrives at the power element 11. the latter moves the valves 16 and 17 using studs 20 and filtering double-shell cylinder 3 to its lowest position. In the lower position is cylindrical. The wall of the valve 16 opens the windows 22, the inlet of the nozzle 14 for the entry of the washing liquid and at the same time blocks the exit of the liquid from the pipe 13.

In this extreme lower position, the cylindrical wall of the valve 17 opens the inlet of the nozzle 15 to discharge the contaminated washing liquid and blocks the entrance of the nozzle 12 for the input of the liquid to be cleaned, and the stand 25 additionally blocks the hole 19 in the bottom of the lower valve 17.

Simultaneous movement of the double-cylinder 3 to the lowest position results in alignment of the grooves 6- and the holes 8 on the working surfaces of the external fixed sleeve 2 and the central glass 4 facing each other, which increases the flow dimensions for the flow of washing liquid during the removal of particles of mechanical contaminants through the internal cavity of the double-shell cylinder 3. The washing liquid coming through the pipe 14 releases the particles of the mechanical contamination of the groove 6 and the holes 8 on the surfaces facing each other. x rhnost outer stationary gil zy 2 .dvuhkorpusnogo cylinder 3 and 4. The central cup contaminated wash liquid flows into the annular cavity 24 shizhney poloyt cylindrical head 10 and is output via the control pipe 15 to the tank for collecting the contaminated wash liquid.

After completion of the regeneration mode and the restoration of the initial flowability of the slotted filter, the power unit 11 moves the valves 16 and 17 and the double-case TLINDER to the extreme upper position governing the filter operation in filtering mode the resumption of the subsequent filter cycle is performed.

A slit filter for cleaning liquids from mechanical impurities from axially arranged axial body of shch-shindric filtering elements with cylindrical heads for controlling the flows of the cleaned and washing liquid simplifies the design, its operation by increasing the regeneration efficiency of the filter slots, and also automates the control of filter operation .
