The installation consists of a cylindrical body 1 with clamps 2. Inside the case there is a filter element with perforations 3, on the outside side to The filter material 4 is expensively installed by a clamping means 5. On the inner side of the collar 2, T1 directing members 6 are provided for centering and sealing the filter element having reinforcing rings 7 and 8. The coaxially arranged central pipe 9 is designed to drain the liquid during backwash through the valve 10 and holes 11. The partition 12 serves to shorten the drainage path of the liquid. The installation has a connecting element consisting of two disks 13 and 14. The disks are set apart from each other by means of a support pipe 15 surrounding the central pipe 9. The connecting element can occupy two positions, abutting one of the crust 2 of the housing 1 ( the right position is indicated in FIG. 1 by the dashed line). For the drive of the connecting element, an eccentrically located lead screw 16 is provided, the screw installed in support 17.X, the screw 16 has a threaded connection with the disk 14, and the sealing of the screws in the cracker is carried out by means of a stuffing box 18. The driving screw 16 is connected to the actuator 19 by means of couplings 20. Limit switches 21 are wired (not shown) connected to the actuator 19. On one and covers 2 of case 1 there is a nozzle 22 for feeding the filtered liquid. On the cylindrical case 1, a regulating or drain valve is installed. apan 23 and valve 24 precipitate. The installation works as follows. The liquid to be filtered is fed through the nozzle 22 into the annular space between the central tube 9 and the perforated filter element 3. Liquid through the perforations 3 of the filter element enters the filter material 4. The solids are retained by the filter material 4, and the cleaned liquid enters the annular space between the filter element, and the housing 1, from where it is discharged through a regulating or drain valve 23. As the discs are spaced from each other at a distance equal to 1/2 of the length of the filter element, t In either of the two positions, one of them is in the middle part of the filter element that does not have perforations. In the filtering process, the filter material 4 is gradually clogged with particles of solid contaminants, as a result of which the hydrodynamic resistance increases and a pressure difference is created. Upon reaching a certain pressure difference between the annular space. above and below the futton element, the backwash process begins. At the same time, using the actuator 19, the friction m: -phth 20 and the lead screw 16 soy), the transfer element is moved from one position to another with a predetermined constant speed along the inner surface of the filter element. During the movement of the connecting member, the filtering process continues and only two narrow sections in the form of a ring corresponding to the thickness of the discs are closed for filtering. Since the pressure in the annular space above the filter element is higher than that in the through channel of the discs, a small part of the already filtered liquid is pushed out of this space into the through channel, and the filter material is freed from solid particles settled on it. The dilution fluid passes through the annular space between the central tube 9 and the support tube 15 and the orifices 11 into the inner space of the central tube 9 and is discharged from there through the valve 10. Depending on the solids content in the filtered fluid, the pressure difference is reached at various time intervals. The filter unit control system (Fig. 4) contains two devices 25 and 26 for receiving data.
    measured pressure and differential pressure switch 27.
    When a certain pressure difference is reached, depending on the conditions of the process, the actuator switch 28 is actuated, and the actuator 19 moves the connecting element from one position to another. After reaching the new position with the connecting element, the limit switch 21 turns off the switch 28. The pressure is increased with the help of the pump. 29 in the supply line for the filtered liquid
    The perforations of the filler element can be made, according to a preferred form, in the form of tapered bores 30, in which the ratio of the diameter of the holes on the inner and outer sides of the filter element is equal to 2.5 times the axis of the bores. the diameter of the holes on the inside of the filter element. The drillings are located offset from each other so that the holes on the outside of the filter element are as close as possible to each other and their depth is around 70% of the total surface area of the filter element. The wall thickness of the filter element is 2j5 perforation diameter on the inside of the filter element.
    Conical drillings 30 can be made with a short cylindrical part (mainly on the inner side of the filter element), the cylindrical part having a length equal to 0-1 of the thickness of the filter element.
    The disks of the connecting element (Fig. 8) have internal external and internal fixing parts 31 to 32, secured with a bolt 33 and an annular intermediate part.
    34, B of the annular space formed between them, a ring 35 is installed with a gap 36. The ije piston ring is clamped with locking parts and has grooves in the joint gap area into which a super-shaped fitting 37, is inserted. To prestress the piston ring with, uncoupling the spring 38, the action of which is indicated by arrows in FIG. 9.
    As soon as the piston rings begin to move from one position E to the other and are in the zone of the filter element with conical bore holes 30, the differential pressure between the annular spaces below and above the filter element as a result of which the piston the rings begin to create a uniform sealing yci. thereby preventing fluid leakage. Also, the fittings 37 are pressed under the action of a pressure difference to the inner surface of the filter element and provide a seal in the area of the butt clearance 36 of the piston rings. Since there is a pressure difference between the annular space under the filter e, filter, and channels inside the discs communicated through the space between the central tube 9 and the supporting tube 15 with the inner space of the central tube S, the piston rings 35 and fittings 37 are also attached to the inner locking parts 31 and compacted installation.
    Due to the presence of these elements, the amount of liquid required for the backing is reduced and the effective filter is also increased;)) due to the provision of the fluid seal between the coupling elements: o: cc vi.
