Description

Technical Field

[0001] The utility model relates to flues, air ducts and coal powder pipelines in the fields of electric power, metallurgy, petrochemical industry, environmental protection, cement, heat, ships and large and medium-sized enterprises, and in particular to an integrated flanging soft connection structure and a non-metallic compensator. Background Art

[0002] The non-metallic compensator is called flanged soft connection after the technical modification. The non-metallic compensator is mainly composed of non-metallic flexible ring belt, metal frame, pressure strip, guide tube, thermal insulation filler insulation layer, etc. when the medium contains particulate matter. From the name, it can be seen that the working body of the non-metallic compensator is non-metallic composite material. It is widely used in steel mills, smelters, petrochemical plants, thermal power plants, garbage treatment plants, cement plants and other smoke exhaust and desulfurization pipelines, civil air defense, ships, environmental protection dust removal and air supply systems, air heating, fan inlet and outlet and other equipment. It can absorb the thermal expansion of the pipeline and the size change caused by temperature changes in the pipeline. It also has the function of shock absorption and noise reduction. It is mainly divided into round and rectangular in terms of appearance and structure. Due to the metal frame, it is difficult to meet the use of narrow and deformed space. Different media have different degrees of damage to non-metallic compensators. Some media are highly corrosive, and some media have particulate matter, which shortens the service life of the soft part of the non-metallic compensator. Many metal frames are intact when they need to be replaced, and the overall replacement naturally generates manpower and material costs.

[0003] Moreover, after years of on-site installation, it has been found that the non-metallic compensators on many devices are damaged in the software, while the flanges are intact. The overall replacement of the compensators has invisibly increased the consumption cost. In some installation locations and methods, only the leather ring belt is replaced, and the operating space is limited and inconvenient. Utility Model Content

[0020] The following is combined with Figure 1-4 , the technical solution of the utility model is further explained:

[0021] Embodiment 1

[0022] like Figure 1-Figure 3 As shown, an integrated flanging soft connection structure includes several layers of non-metallic fabric layers, and adjacent layers of non-metallic fabric layers are vulcanized and bonded to form a full-length skin 1. That is to say, according to different working conditions and working media, a matching material structure is selected to achieve high temperature resistance, flame retardancy, acid and alkali corrosion resistance and other problems. In this embodiment, the non-metallic fabric layer is a full fabric material, and the material is accurately selected by using the parameters provided on site and combining the shape of the medium (temperature, acid and alkali, particles, solid, liquid, steam), and the selected fabrics are vulcanized and bonded in sequence to form a skin.

[0023] Specifically, the two sides of the skin 1 are folded toward the center of the skin to form a reserved flange 2, and a plurality of openings 3 are provided between the reserved flange 2 and the skin, so as to evenly flatten the reserved flange on the flange after the skin is put on the flange. In other words, the upper and lower sides of the skin are folded outward for a section to form a reserved flange, and when the skin is subsequently put on the flange, the reserved flange can be flattened and pressed on the flange ring surface, and an opening is provided on the reserved flange, so that the originally integrated reserved flange is divided into several sections, and the reserved flange can be flattened on the flange ring surface section by section, and the reserved flange is more evenly flattened.

[0024] In some embodiments, Figure 2 As shown, when the reserved flange 3 is flattened on the flange, the opening is enlarged to form a gap, and a filling block made of the same material as the skin is bonded in the gap. That is to say, when the reserved flange originally in the same plane as the skin is folded outward and flattened on the flange ring surface, the opening between the original reserved flanges is enlarged to form a gap, and the shape of the gap needs to be customized on site, and a filling block made of the same material as the skin needs to be bonded in the gap.

[0025] In some embodiments, Figure 3 As shown, the reserved flange 2 and the skin 1 are sewn together by two parallel suture lines; a bulging channel is formed between the reserved flange 2 and the skin 1 between the two parallel suture lines, and a metal soft strip 5 is passed through the channel so that the reserved flange can be quickly folded and flattened on the flange. In other words, a metal soft strip is inserted at the junction of the reserved flange and the skin, so that the decomposition position of the reserved flange and the skin can be distinguished, and it is also more convenient and quick when the reserved flange is flattened.

[0026] Specific operation process: The materials used for flanging soft connection vary according to the medium. The only constant is that no matter what medium it is, it is not made of one layer of material. Therefore, how to integrate multiple layers of different materials is not a simple matter. It is a repeated test. First, we must fully understand the performance of various fabric materials. Which material and how to arrange it to achieve the best effect are all particular. First, select the material, determine the arrangement order, and start cutting. If the shape needs to be made, the pattern needs to be made. Generally, the innermost layer should be 20mm larger than the actual parameters, and the second, third, fourth... will be reduced by 2mm in turn until the last layer, which is the outermost layer, is to ensure that the actual parameters can meet the size consistency of multiple layers after flanging. After the materials are laid, proceed to the second step of vulcanization bonding of one layer with another. Take out the cut first layer, apply glue (customized glue according to the use needs) on the material, apply the second layer, and continue to apply glue on the second layer, and cover the glue in sequence until the last layer. After applying the glue, leave it at room temperature for 60-90 minutes before it can be shaped. Hold the vulcanized end and apply glue outside the line according to the pre-drawn positioning line, then take the other end and cross-stack it, and vulcanize it naturally for 30 minutes. Try to press the vulcanized part with a flat object each time, and the cured part will be more solid.

[0027] After the two heads are closed, the shape can be arranged. The circular shape needs the width of the opening to the edge. The distance between the openings and the distance of the large diameter can be farther, and the distance of the small diameter can be smaller, so that the edge can be turned out evenly and flat. After the openings on both sides are opened, the edge is turned over. A layer of arc-shaped edge with the same material as the outer layer of the body is laid under the opening. The edge width is the parameter that needs to be provided on site. It needs to be cut as wide as it needs to be. Glue it on top, turn the opening to the edge and press it firmly. Curing for 20 minutes, cover it with a layer of arc-shaped edge that is the same as the first layer. The upper and lower edges play a role in covering the opening to increase strength and external beauty. Compared with the circular and rectangular shapes, there is no need to open many openings. Only one opening is needed at the corresponding length and width corners. After the edge is turned over, this opening is the position of the corner, and then the material of the corresponding parameters is cut out for the edge. The production process of different shapes of special shapes is the same, and the curing time needs to be increased. The difference is that the corners and edges of the special shapes need to be repeatedly glued and cured once. Finishing and trimming burrs are completed.

[0028] Embodiment 2

[0029] like Figure 4As shown, a non-metallic compensator includes a flange, an integrated flanged flexible connection structure is sleeved inside the flange, a reserved flange in the flanged flexible connection structure is flattened on the flange, and a through hole corresponding to the opening on the flange is opened on the reserved flange. That is to say, after the integrated flanged flexible connection is sleeved on the flange, the reserved flange is folded and flattened on the flange ring, and the flanged flexible connection is rotated to align its through hole with the opening on the flange, and then the bolts are screwed in to tighten it during installation. The overall installation is quick and convenient, and the sealing is good. At the same time, when it needs to be replaced later, there is no need to replace the flange as a whole, and a new flanged flexible connection can be replaced on the basis of the original flange.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
