Description

Existing filters for contaminated liquids require periodic assembly to clean filter surfaces. The inventive invention is designed to eliminate this disadvantage by the combined use of disk frames mounted on a hollow shaft and fixedly seated inside the casing of the scrapers wiping dirt from the filter surfaces while the shaft rotates.

In FIG. 1 depicts a vertical section of the proposed filter: FIG. 2-side view of it.

To the housing 1 with end walls 8 in the upper part a frame 5 is riveted with grooves 4 for sealing and ears 34 for articulated rollers 3 & a folding bolt 36. In addition, the lugs 37 are attached to the frame 5 for the rollers 48 with the hinged hinges of the cap IS, on which there is a valve 5 for de-airing. In the frame cut-outs, studs 86 attach. 19 inserts with bearing holes, in which the hollow shaft rotates, 16 with hermetically fixed circular filter frames 7, consisting of wavy sheathed X0.1ICTOM 50 metal disks with four radial grooves, with the part of the disk circumference, which is adjacent to the shaft, is left smooth and there are sockets attached to it on both sides, the S4 with the four cabbath which is a continuation of the grooves on the disks. Between the frames are placed

Fixed oir scrapers lined with scrim, used to clean the dirt from the frames 7. The frame 7 discs with sockets 24 and rubber pads 83 are mounted on the shaft 16 and pressed against the support washer 80 by a nut 81, thereby creating a friction force between the discs and the shaft between them integrally during rotation, the grooves of the sockets 84 are located against the holes 35 in the shaft. 16 through which the filtered fluid passes. The shaft b rotated by the pulley 17 is sealed by pressure sleeves 18 and is kept from longitudinal movement by a washer 80 abutting against the shoulder of the insert part 19 and an abutting ring 43 supported on the sleeve of the insert part 19. On the side of the pulley 17, the shaft hole 16 is plugged with a plug 45, and the second end of the shaft hole 16 is open and serves to exit the filtered fluid into the iron canter 46, mounted on the housing 1, to which the fitting 47 is draped from the bottom to drain the filtered liquid, and to filter the liquid is supplied through the fitting 4 located When filtering, it enters through the opening 5 in the housing 1 and through the gate 10 into the reservoir 15, having a viewing glass 38 and a drain valve 38 attached to the housing 1. From the reservoir 15, the dirt is removed through the opening 6 into the gate valve 49. The manhole of the tank of seals 15 is hermetically

closes with screw 50 with bracket 51 and serves for inspection. The filter cover 13 has a frame 38, to which the ears 39 are riveted, supports for 40-lambs, and two iron strips 8 form a wedge; 9 a balancing lid 12, into which the pipe 27 is propped up, with openings at the bottom of S8 located in the middle between the two filter frames. The introductory end of the pipe 27 is sealed in the cover 12 with the help of washers 29 and nuts 11.

Before starting the filter, the cover 13 and all valves are tightly closed, and the air valve 31 is opened, and then pressurized fluid is fed through the fitting 4 into the housing 1. The liquid passes through the filter canvas 50 into the inside of the frames 7 through the radial grooves in the discs and sockets 54 , and enters through the openings 25 into the hollow shaft 16, from where it goes to the cholot 46 and through the fitting 47 comes out as a finished product or, as a semi-finished product, it goes into further processing. During the operation of the filter, the Splash 17 rotates the shaft 16 with the filter frames 7, so that the fixedly mounted squeezers 52 scrape the dirt from the outer surfaces of the canvas 30, which are shared with the frame 7. In case of complete contamination of the filter canvas 30, during continuous operation, the shaft 27 under pure water is supplied by pressure, which through the openings 28 is jetted between the frames 7 and thoroughly flushes the canvas. The tank 15 serves to remove the dirt from the hull 1 without interrupting the operation, for which the valve is closed for the cleaning time in the lower part, thus stopping the liquid from the hull 1 and accumulating in the tank / 15 grease through valve 49, -

Continuous bag sifter filter, distinguished by cumulative use: 1) disc frames 7 mounted on a hollow shaft 16 so that the cavity between the bag and the surface of the frame communicates with the shaft floor, 2) fixedly inside the casing of the scraper 52 for removal from the surface of the bags filtered shit
