SUMMARY OF THE INVENTION: in a bag filter, the sleeves are made of integral length and having hanging slings equipped with rods and pins located in the holes of the rods, the upper ends of the rods being located in the holes of the tires. and the pins are made with locking elements, which allows the use of long vertical filter bags with efficient regeneration over the entire area and to stabilize the conditions and quality of dust cleaning. 1 C.p. f-ls, 9 ill.

Description

The invention relates to the purification of gas from dust by filtration and is intended for use in the construction materials industry, chemical, mining and other industries.

An object of the invention is to increase productivity.

Figure 1 shows a bag filter, General view; FIG. 2 is a section AA in FIG. 1; in Fig.Z - cap, top view; figure 4 - docking ring element, top view; figure 5 - rod, General view; figure 6 - node locking pin; in Fig.7 is a section bB in Fig. 1; Fig. 9 is a shutter plate in working condition, front view.

The bag filter includes a housing 1 with a distribution grill 2, which is connected by a system of nozzles 3 to a dusty air chamber 4. Filter sleeves are put on each nozzle 3, which are closed in the upper part by a cap 5 and made up of the upper cylindrical part 6, the lower cylindrical part 7 and the compensator 8. Part 7 is attached to the compensator 8 through the connecting ring element 9, between

in parts 6 and 7, a docking ring element 10 is arranged.

The cap 5 has pins 11 spaced apart and outwardly directed along the perimeter, to which pins 12 on the docking ring element 10 correspond in a plane arrangement (Fig. 8). On the pins 12, the frame 13 is fixed rigidly by any known method, for example, bolts inserted into the corresponding hole in the end part of the pin 12 and passed through the hole in the frame 13.

The filter used rods 14 at the ends with holes a and b, of which hole b has the shape of an open oval and is locked by a movable bar 15, composed of two halves, with means for fixing the position, for example, such as a clamp-bolt (Fig. 9).

The rods 14 serve as spacers for part 6 of the sleeve, for its rod is fixed in the pins 11,12 so that the shoulder 16 protrudes beyond the sleeve. The sleeve to fit it into the corresponding guide hole in the horizontally fixed inside the corset

nyca 1 to guide rail 17. Dimensions or number of tires 17 are selected from the conditions of operational reliability and the ability to accept the ends of all the rods 14.

Before putting the bag filter into operation, the lower structure is assembled, for which purpose a compensator 8 is put on the pipe 3, an annular element 9 is mounted and the lower part 7 of the filter is hung. Any other assembly sequence of the lower part 7 of the sleeve is permitted from the operating practice conditions. The lower structure was fastened to Tot on the ring element 10. The fastening of all the constituent elements is carried out by ties (not shown in the drawings). :

From the annular element 9 to the annular element 10, slings of the suspension 18 made of flexible material, for example, kapron strands, are placed outside the lower part of the sleeve 7.

The docking ring member 10 is secured to a frame 13, which is connected to the shaking mechanism as follows.

On the distribution grid 2, equidistant from the nozzles 3, a rack 19 is placed with a supporting platform 20, a shock absorber 21 and a supporting platform 22 on which a vibrator 23 of type IV is mounted.

On the supporting platform 22, a frame 13 is fixed.

A cap 5 is attached to the upper part 6 of the sleeve and the assembled structure is mounted on the annular element 10 so that the pins 11,12 are oriented in a vertical plane. ..

Then the rods 14 are installed. To do this, the end is closed by a hole and inserted into the corresponding guide hole in the tire 17, the holes and the rods are placed on the pins 11 of the cover 5, fixing the position with the locking bolt 24. The open hole b of the rod is placed on the pins 12.

By adjusting the position of the pin 12 in the hole b, the required tension of the sleeve part b is created, fixing the position with the movable bar 15. The rod 14 is locked on the pin 12 as described above.

Thus, in a static state, and this means in the filtering mode, the upper part 6 of the sleeve is tensioned by the rods 14, and the lower 7 by the annular element 9,

When the filter is turned on, dusty air is fed through the pipe 25 into the cavity 26 of the chamber 4, from where it enters the cavity through the nozzles 3 into the cavity of the filters composed of parts 6 and 7.

The captured dust settles on the inner walls of the filters and, after intermittent shaking, accumulates in the chamber 4, from where it is periodically removed.

Due to the reciprocating movement of the pad 22 and the frame 13 rigidly fixed thereon, the free ends of the forks of which are rigidly connected to the annular element 10. The filter parts 6 and 7 come into motion.

The upper part 6 of the filter is stretched by 14 to stabilize the structure of the filter material and the quality of the cleaning, therefore, during the regeneration, the entire upper part 6 is shaken.

The lower part 7 of the filter is tensioned by the ring 9, and the elongated position of the sleeve part 7 is fixed by the suspension slings 18.

Similarly, the entire surface of the filter portion 7 is shaken.

An advantage of the proposed bag filter is its simplicity of design and high technological reliability. The possibility of using long vertically elongated bag filters with their efficient regeneration over the entire area makes it possible to stabilize the conditions and quality of dust cleaning, as well as to reduce the dimensions of the filter unit in the horizontal plane.
