Description

one

The invention relates to devices for tensioning the sleeves of fabric filters and can be used in any of their designs, except for frame ones.

The purpose of the invention is to simplify the design and increase the reliability of the device.

FIG. 1 shows the device, a general view (in the initial period of the filter); in fig. 2 - also (after additional in the process of tensioning the sleeve); in fig. 3 shows section A-A in FIG. one; in fig. 4 — node 1 in FIG. one.

The device for tensioning the fabric filter sleeves includes a spring-loaded expansion cone located in the lower open end of the sleeve 1 in the form of two rings 2 and 3 of different diameters, forming a conical surface. A cylindrical bar frame A is rigidly attached to the inner ring 3, the lower open end of the sleeve 1 is attached quickly with a detachable connection 5 to the glass 6 fixed to the support flange 7, which is mounted above the hole in the tube grille 8. The glass 6 and the flange 7 are filled with holes 9 through which the rods of the frame 4 are passed, which in its lower part is provided with a removable ring .10 with eyelets P. The removable ring 10 is connected to the supporting flange 7 by means of extension rod 12. Between the inner rings 2 and 3 on the outer side of the sleeve 1, the outer ring 13 is fitted with the lugs 14 and tension springs 15, one ends of which are fixed in the lugs 14, and others are attached to hooks 17 welded to the support hooks 17 through chains 16. flange 7. Glass 6 and flange 7 constitute an assembly unit that combines

all elements of the sleeve tension knot. The fastening of the support flange 7 to the sleeve-shaped grid 8 is carried out by means of bolts 18 for connection. The sealing of the joint is achieved by installing a gasket 19 when installing the tension hose under the influence of tension springs 15 by installing an outer

0 rings 13 in the plane between the inner rings 2 and 3 of the spacer cone. During operation, changes in the length of the sleeve are selected by the spring 15, and the individual adjustment of the tension of each sleeve individually by hooking the necessary links of chains 16 to provide the required tension for hooks 17. After using the possibilities

0 pulling the sleeves using chains 6 and springs 15, manually pulls the sleeves, for which chains 16 and springs 15 are removed, from hooks 17 and lugs 14, springs 11 raise

5, the frame with the rings 2 and 3 in the upper position, the slack of the sleeve is manually selected, the springs 15 and the chains 16 are put in place and provide the constant required tension of the sleeve 1. The use of extension springs in the device greatly simplifies the design and its intensity. assembly unit of the support flange and connected

go hard with him glass allows

assemble the entire internal part of the device separately in stationary conditions, ensuring good adjustment of the uniformity of the rod bar motion, thereby increasing the reliability of the device.

The presence of a rod cage inside the sleeve ensures good filtering of air from dust in this area and

eliminates the possibility of narrowing the sleeves in this area.
