[0021] As shown in the figure, an axial bandage pleated cloth bag comprises a cloth bag body 1, a plurality of groups of axial fixed points 2 are arranged on the cloth bag body 1 along the axial direction of a bag cage, and each group of axial fixed points is pulled and fixed by one or more axial fixed strips. In the embodiment, a plurality of fixed points are selected.
[0022] The number and position of the axial fixed points are matched with the bag cage 3, and the number of groups is determined by the number of pleats of the cloth bag. In general, one group forms a pleat bottom (in order to strengthen the rigidity of the cloth bag, a plurality of groups can also be used, for example, two groups of fixed points are arranged in close proximity, and the two groups of fixed points form a pleat).
[0023] The fixing point 2 can be located on the inner wall or the outer wall of the cloth bag, and is preferably located on the inner wall.
[0024] The cloth bag body 1 is folded on the outside of the bag cage 3, and the axial fixing strips are alternately located between the bag cage support rods 4. The bag cage support rods 4 and the axial fixing strips respectively form the alternating fold top 5 and the fold bottom 6 of the cloth bag.
[0025] The “fixing” of the axial fixing strip and the fixing point in the present scheme can be firm fixing or have some movement allowance, as long as the axial fixing strip can be pulled to form a fold.
[0026] The axial fixing strip in the present embodiment can be rigid, such as an axial fixing rod. When the fixing rod is used, the fixing can be connected by the following mode:
[0027] The axial fixing strip can also be flexible, such as an axial belt 7. When the flexible fixing is used, a tensioning device 8 can be added. The tensioning device 8 tightens the belt to increase the rigidity.
[0028] Through different fixing modes, the following bag bottoms can be formed: Figure 2 . Figure 4 As shown
[0029] One kind of bag bottom: the bag bottom pressing cover 11 presses the filter cloth to press the bag bottom upper pressing cover 12, and the screw nut is tightened to form the bag bottom,
[0030] One kind of bag bottom: the bag bottom upper pressing cover 12 is fixed on the bag cage bottom. The bag bottom pressing cover 11 presses the filter cloth to press the bag bottom upper pressing cover 12, and the screw nut is tightened to form the bag bottom,
[0031] Figure 2 The upper end of the axial belt 7 is fixed through the tensioning plate 13.
[0032] Figure 3 As Figure 1 A-A view of the axial belt 7 passing through the fixing point 2 and hanging on the hook 9.
[0033] Figure 4 The bottom of the axial belt holds the bag cage bottom, and the upper part is bent to hook the bag cage support frame, so that the axial belt is fixed with the bag cage.
[0034] Figure 5 The bottom of the axial belt is hooked on the bag cage support frame, and the upper part passes through the bag cage upper cover. The nut is used to press the bag cage upper cover to tighten the axial belt.
[0035] In the present embodiment, the fixing mode is as follows:
[0036] Basic fixing:
[0037] The fixing point is a fixing hole set on the inner wall or outer wall. The fixing hole can be a strip of cloth directly sewn on the cloth bag body, with a hole in the middle for passing through (by fixing the two ends of the cloth strip and reserving a fixing hole in the middle), and the axial fixing strip passes through the axial fixing hole along the axial direction of the bag cage.
[0038] Optimized fixation:
[0039] During soot blowing, the bag requires backblowing. For longer bags (e.g., over 3 meters), backblowing can cause the bag to expand and contract significantly, hindering its return to its original position. To prevent this, an intermediate connector is provided. One end of the connector connects to the axial strap and the other to the bag cage. This connector can be a hook 9, which can be positioned circumferentially along the bag cage. One end of the hook pulls on the axial retaining strip and the other end pulls on the bag cage. This function prevents the bag from expanding and contracting significantly during soot blowing due to its length.
[0040] Both ends (or one end) of the axial fixing strip are pulled on both ends of the pull plate or bag cage.
[0041] In addition, a strap 10 ( Figure 4 As shown in the figure). Do not use too many straps. Keeping a small amount can also reduce the expansion of the filter bag during dust blowing.
[0042] Figure 1 The structure shown corresponds to the production and use process:
[0043] Filter bag manufacturing: On the filter cloth, sew the cloth strips at the corresponding positions of the pleats at the bottom, sew the longitudinal seams, sew the bag opening, insert the axial belt, and sew the bag bottom.
[0044] Filter bag and bag cage installation: Install the filter bag into the hole of the flower plate, and the bag cage into the filter bag, and push up the top of the pleats to form. Tighten the axial strap, and wrap the bottom around the bottom of the bag cage to form the bottom of the pleats. Tighten the axial strap and fix it to the bag cage support frame.
[0045] Remove the filter bag and bag cage: Loosen the axial strap fastening device. Pull out the bag cage. Pull out the filter bag from the hole in the flower plate.
[0046] Figure 2 The structure shown corresponds to the production and use process:
[0047] Filter bag manufacturing: On the filter cloth, sew cloth strips at the corresponding positions at the bottom of the pleats, sew the bag opening, and insert the axial belt.
[0048] Filter bag and bag cage assembly: Place the filter bag in the bag cage and push up the top of the pleats to form the shape. Hook the bottom of the steel wire to the bag cage support frame and the top of the steel wire to the pull plate. Tighten the screw to push the pull plate upwards and tighten the steel wire to form the bottom of the pleats.
[0049] If the wire stiffness is not enough, the wire is hung on the bag cage hook through the filter cloth. In this way, when the dust is blown, the filter bag is prevented from expanding too much. The screw nut presses the bag bottom cover on the filter cloth and on the bag cage bottom.
[0050] Filter bag and bag cage are disassembled: the bag cage and filter bag are pulled out from the flower plate hole. The screw rod is twisted, the pull plate is loosened, and the hook part of the steel wire is disconnected. The steel wire is disconnected from the bag cage hook through the filter cloth. The bag cage is pulled out from the filter bag.
[0051] The above description is not only suitable for circular cloth bags but also for various shaped cloth bags. Filter cloth, filter screen and metal fiber felt can be used. The technical features not described in the utility model can be realized by or using the prior art, which will not be repeated here; the above examples and drawings are only used to illustrate the technical scheme of the utility model and are not a limitation of the utility model, the preferred embodiment is described in detail, and those skilled in the art should understand that the changes, modifications, additions or replacements made by those skilled in the art within the essential scope of the utility model do not deviate from the purpose of the utility model, and should also belong to the protection scope of the claims of the utility model.
