SU97421A1 - Filter for juices of sugar production and other suspended mixtures - Google Patents

Description

The invention relates to filters for saturation of juices of sugar production and other similar weighed mixers, E made in the form of a package of odd odd and even frames filtering through a cloth, with washing the precipitate with a filtered liquid or water by changing its direction.

For this purpose, collapsible frame filter presses with implanted cloth napkins are known in the industry. Chamber bag filters are also known in which filter laminae n-1 serve as lattice scaffolds, which enclose from the filter cloth, on the surface of which a deposit is deposited. Removal of sediment in these filters is carried out by the reverse flow of the filtered liquid, and to prevent the cells from bulging between the filter elements A of the stack. And spreading grids.

The proposed filter allows, in addition to removing the precipitate, to efficiently wash the filter cloth wipes alternately from both sides, freeing them from the precipitate. For this purpose, in the proposed filter, all the frames are syabzhen from two and opposite sides of the application with two openings in each, forming left and right juice and steam inlets on the sides of the filter; moreover, the odd frames are provided with steam bubblers and alternately, one after the other, communicate with the left, then with the right soy and steam inlets.

In addition, spacer grids were installed in the odd odor frames, and a four-way valve was used for washing the filtering fluid when the sludge was washed.

FIG. 1 depicted ence species

odd filter frame; in fig. 2

all parts of the filter frame; in fig. 3 - filter scheme in terms of four-way; spraying; in fig. 4 and 5 - the same scheme with different

the position of the four-way valve when washing the filter cloth with. both sides.

The filter consists of a packet of meters, of which the odd frames 1 are dirty, and the even frames 2 are filtering.

The Tjcaiib filter in the WilTe napkins, worn on both sides on even 11s 2, is sandwiched between the frames. All frames (even n odd) are fastened to two frontal shields 3.

In odd frames / spacer grids 4 are installed, positioned between the filter surfaces of the SHEETS of the adjacent 2 н s filter frames; 1 is used to prevent the fabric from bulging when washing it in the direction of the inverse liquid.

All frames on two opposite sides have tides 5 with two openings in each tide; after the assembly of phi, ltra, these holes form on the sides of the filter the left and right juice channels 6 and 7 and the steam inlets S and P.

The odd frames / are supplied with bubbling ceramics 10, the cavities of which through the slots // alternately one after another communicate with the left channel 6, then with the right channel 7; bubblers 10 also communicate with steam channels S, 9.

The even frames 2 are provided with faucets 12 for the passage of the filtered liquid.

In order to change the direction of the moving reliant bone in the water during washing the filter sludge / is equipped with a four-way speck 13.

In a working state, as it is, kazai str, 1kami pas FIG. 3, the filtered liquid through the speck 13 enters the channels 6 to 7, passes through the slots 11 in the cavity of the odd frames /, (it is inserted through the fabric from the strip;; ; tsol; deposited on fnl1) Tri: Tsei fabrics B cavity (Pepetin) x frames.

After; acopleni throat ;; on the base of the fabric, the valve 13 switches to the position indicated; ia fig. 4. In this case, the fi gr is removable; J1; l; -: the host TO.Tbiu host; s

channel G, and Kana; 7 turns out to be connected to the exhaust branch pipe 14. Filtered liquid enters only cavities of the group of odd frames connected to channel 1 in the cavities 6. Liquid, filter, feed in the cavities of the even frames 2 i, p) and the closed racks 12, It goes further through the fi rm of the fabric from the side of its side, into the noloet; 1 | of the group of odd frames connected to the channel m.

At this time, the channels 8–9 are turned on by a nara, which, entering through the bubblers 10, stirs up more difficultly and prevents the accumulation of solid particles in the lower part of the greaseless three-dimensional frames.

To wash the filter-inlet cloth on the other side, the four-way valve 13 is installed in position 1, shown in fig. five.

As already mentioned, water can be used for removing sediment and washing the filter cloth instead of the filtered liquid.
