Description

one

The invention relates to cleaning devices and can be used in the chemical, metallurgical, mining, cement and other industries, as well as in transport and agriculture.

The aim of the invention is to ensure the regeneration of the tape, reducing the size of the filter and the effectiveness of cleaning.

FIG. 1 shows fi; P) Tr, vertical section; in fig. 2 - case, from the top, top view; in fig. 3 shows section A-A in FIG. one; in fig. 4 - shield; in fig. 5 - section along the axis of the hole of the frame; in fig. 6 - iditoc with pinch rollers and yarns.

The filter includes a housing 1, inside of which are two parallel-arranged perforated drums .2 with a tape 3 wound on them, made of parallel-lying fibrous threads 4. The tape 3 is attached with ends to the drums 2 and each thread 4 (or a group of threads) is passed between the drums 2 parallel to their axis. The holes 5 in the flap 6 are arranged in horizontal rows 7 (FIG. 4), with each hole 5 in the underlying row displaced horizontally with respect to the corresponding hole in the outgoing row so that these holes Adjacent rows form inclined rows 8. The top hole in each inclined row is horizontally displaced, and the P1epia to the lower hole in the same row is smaller than the distance 9 between adjacent inclined rows horizontally. On both sides of the flap 6 along the horizon; and 1 two pairs of pinch rollers 10 are placed, pressing the tape 3. On the drums 2, the end disks 11 are reinforced, and at least on the disk 11 of one drum 2 circumferentially a toothed crown with teeth 12, which are in contact with the spring-loaded rod 13. The rod 13 has an axis of rotation 14 fixed on the housing 1, is fitted with a spring 15 and is connected to the flap 6. The inlet pipe 16 is made in the upper part of the case 1, and two branch pipes 17 are in the side part it and connected through the glands 18 and cylindrical vist s 19 on the end disk 11 rolls 2 with their inner cavity 20. Drums 2 are provided with two drive and braking device 22. In the lower part of the housing 1 is located 23 1lesborpik u.

The filter works as follows. During the filtration process, the polluted air flows through the inlet pipe 16 into the body 1, and then passes through the fibrous layer of the filaments 4 wound on the perforated drums 2, where they are cleaned off like a whole fiber filter. Once inside the drums 2 through the perforations, the purified air enters through vystugz 19 in

10 branch ducts 17. After clogging the layers of filaments 4, the dust regenerates. To do this, the air supply to the filter is stopped and the drive 21 is turned on, which, rotating one of the drums 2, winds the tape 3 on it and winds it from the other drum. This provides the necessary tension of the mite 3, which is regulated by a braking device 22, which creates a rotation on the axis of rotation of the drum 2, from which the tape 3 is wound.

20 vrashnya drum 2 teeth 12 on its end disks 11 is caused to vibrate 1ntape 13, which shakes the flap 6 together with 5 threads 4 in its openings 4. This ensures shaking of dust which falls along the gaps between the inclined rows into the dust collector 23. Because the gap 9 between the inclined rows of holes is greater than the horizontal displacement 24 of the upper orifice relative to the lower hole, the fuses do not fall on the threads of the adjacent an inclined row and freely evacuated to a dust collector 23. So 3 that is pulled through plate 6 and purified by aching. Then, if necessary, it is also pulled in the opposite direction, etc. n is set up so that the middle part is spaced against the shield 6.

More than B1) 1, a high degree of regeneration in this filter is achieved due to the short-term separation of the filaments using a shield, which ensures free release of dust particles from the surface of each piti. A decrease in the size of the filter is achieved by increasing the velocity of the gas through the fibrous layer (about 1 m) but compared with the movement through the fabric mite

45 (about 0.01 m / s), as well as a significant decrease in the distance between the drums 2, since the filtering takes place in the layer on the drums, and not on the stretched section of the tape between them. Improving the degree of gas purification is achieved by increasing the thickness of the filter layer, as in all other fibrous absolute filters.
