Description

The modern thickeners used in sugar factories FOR a preliminary increase in the crushing concentration of suspended matter lered to the vacuum vacuum cleaner 1 1, consist of iron hole shafts, heated by rail ж 1 of a cable, and covered with a hard cross section; every four patrons; iBi perpushu with i. Tpiybok (and B-Bieipxy nuts of each cartridge; section tubes converge at the gold distributor, which is OBHisaH with OiM1munik1altimy for dilution and pressure and pericodicheok through this slog | H1 communication, the transmission occurs yes: W-1NI or rarefaction-g.

The main "disadvantages of thickeners of this type are the following:

1. A non-significant filtering surface, 1 triple to one cubic 1 meter of capacity reservoir, thickener.

2. Live; The cross section of the same single pyran and the m: m | m | with peep holes is only 40% of the surface of Patría, serving as oOHioiBbi for the filter cloth.

3. Larger pai3iMe pbi of thickeners are shown to reduce the size of the ToiBi; increase the height of the reservoir and, as a matter of fact, the height of the parasite, which causes an uneven height.

4. The location of the hubs in the tank is such that the condensed -Maos entering at the top does not pass evenly near the surface of the pairen, and its middle part between the four cartridges constituting the ax section can descend without crushing.

5. Difficulty (detachable connection. And. The upper parts of the patronage with the spool distributor N1e1m.

6. Iron consumption per thickener (Oliver Borden system) in 78 square meters. meters is eight tons with a cartridge filtration system.

To eliminate the above drawbacks of thickeners, the present invention proposes replacing cylindrical heavy cartridges with light M-frames, which can be flat, cylindrical or any other schrofil, depending on the convenience of their location, charging, unloading and care.

As can be seen from the drawing, in FIG. 1 of which a diagram of the apparatus is given (section along AB of FIG. 2), and FIG. 2 - spool dispenser, between the filter frames / special device inserts 2, which should hold the canvas on the surface of the filter frame 1 when the condensed sediment is blown off and allow free passage from the top of the tank to a thickened Mass near the surface of the filter frame.

The inserts are frames of the same dimensions with filter frames | Kami and are made of iron strip, moreover: the strips of iron are located a small distance from each other and perpendicular to the plane of the filter frames. The plates are interconnected by horizontal plates of the same iron strip. The intermediate frame thus made is wrapped with iron wire in a horizontal direction with a distance of 30-40 mm M1 between the turns. The wire is recessed in the grooves made in the edges of the plates so as not to create obstacles when assembling and disassembling the filter frames for cleaning in case of idle driving or when replacing it.

The condensed liquid enters the top of the tank, is distributed between the filter frames | Ka, Mi,

t. €. inside the liner, and comes out below.

The described thickening agents, both flat and cylindrical, can be used as bag filters like Proxier filters and other systems for filtering liquids with a small amount of suspended substances.

The frames in such filters are not removed to remove dirt, and the dirt is washed off from the canvas by a current of water, dyes supplied in the direction opposite to the opposite direction.

filtering. All existing so-called “mechanical filters in sugar factories can be easily rebuilt to the proposed method of operation.

Subject invention

AnnaipaT for filtering liquids with wasp removal, for example, from the filter cloth with a reverse flow of water, characterized in that to keep the filter cloths at a certain distance from each other, the apparatus is provided with hollow inserts with wire winding, which have the shape of a filter frame and are located between each pair filter frames.
