Description

Technical Field

[0001] This utility model belongs to the field of textile duct technology, and more specifically, it relates to a textile flame-retardant hollow energy-saving duct. Background Technology

[0002] Textile ducts are flexible air distribution systems made of woven fabric. Due to their excellent flexibility and space utilization efficiency, textile ducts are widely used in air supply systems in large commercial complexes, industrial plants, stadiums, and other spacious areas. Currently, during hot air delivery, the long layout of ducts within factories and the lack of insulation cause the temperature of the transported gas to dissipate from the duct walls, making it difficult for the air temperature at the duct's delivery point to reach the initial temperature set by the blower. This results in significant heat waste. Furthermore, the lack of flame-retardant properties in the fabric of traditional textile ducts allows open flames to spread along their distribution path, leading to uncontrollable fires and increased fire damage. Additionally, traditional duct assembly requires multiple sets of bolts and nuts tightened into the flange holes at the duct's ends, making the process cumbersome and complex, severely reducing the efficiency of assembling and disassembling multiple textile duct units. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a textile flame-retardant hollow energy-saving air duct, which solves the problems of severe heat loss from the air supplied by traditional textile air ducts, the flammability of the duct fabric which can spread fires, and the low efficiency of the bolt-and-nut assembly / disassembly method used to connect multiple textile air ducts.

[0004] This utility model provides a textile flame-retardant hollow energy-saving air duct, including a fabric strip; a sling is sewn to the upper side of the fabric strip, and an outer tube fabric is sewn to the lower side of the fabric strip; an insert plate is glued to the outer side of the outer tube fabric near the front end, a sealing ring is glued to the front side of the insert plate, a pressure plate is glued to the outer side of the outer tube fabric near the rear end, a heat insulation sleeve is nested inside the inner side of the outer tube fabric, and a plastic film is glued to the inner side of the heat insulation sleeve; an insert plate is glued to the inner side of the plastic film near the front end, an assembly cylinder is rotatably connected to the outer side of the insert plate, a handrail frame is welded to the rear end of the assembly cylinder, and a pressure plate is glued to the inner side of the plastic film near the rear end.

[0005] In at least some embodiments, the thermal insulation sleeve is a through-tube structure, and the entire through-tube structure of the thermal insulation sleeve is made of flexible aerogel.

[0006] In at least some embodiments, the outer tube fabric is a tube structure that runs through the front and back, and the outer tube fabric covers the outer side of the insulation sleeve. The outer tube fabric is made entirely of aramid fiber.

[0007] In at least some embodiments, the pressure plate is made entirely of flame-retardant plastic. A through hole is provided at the center of the pressure plate, and six sets of circular hole grooves are provided on the rear side of the pressure plate. The circular hole grooves are arranged in a circular array around the horizontal central axis of the central through hole of the circular hole groove. A threaded structure is provided on the outer side of the pressure plate near the rear end, and a ring plate structure is provided on the outer side of the pressure plate near the middle. A hanging plate is provided at the top of the outer side of the ring plate of the pressure plate. A circular through hole is provided on the front side of the hanging plate, and a sealing gasket is bonded to the rear side of the ring plate of the pressure plate. The sealing gasket is made of silicone material.

[0008] In at least some embodiments, the insertion plate has a through hole running through the front and back at its center, and six sets of directional insertion rods are welded to the front side of the insertion plate. Each set of directional insertion rods is a cylindrical structure, and the six sets of directional insertion rods are arranged in a ring array around the through hole of the insertion plate.

[0009] In at least some embodiments, the connecting cylinder is a cylindrical structure that runs through the front and rear. The inner side of the connecting cylinder is provided with a threaded structure near the front end, and the threaded connection of the connecting cylinder is engaged with the threaded structure on the outer side of the pressure plate.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. In this utility model, on the one hand, the low thermal conductivity of the nanoporous structure of the flexible aerogel insulation sleeve enables the insulation sleeve to form a heat insulation layer between the outer tube fabric and the plastic film, preventing the heat energy from being conducted and lost on the outer tube fabric during the long-distance transmission of hot air inside the duct, thus avoiding the waste of heat energy in the duct and saving heat energy. On the other hand, the excellent flame retardancy and self-extinguishing properties of the aramid fiber of the outer tube fabric prevent open flames from burning along the distribution structure of the textile duct, effectively preventing the spread of fire.

[0012] 2. In this utility model, the threaded engagement transmission structure formed by the inner side thread of the assembly cylinder and the outer side thread of the pressure plate operates, causing the assembly cylinder to drive the pressure plate to move horizontally back and forth along the directional insertion rod. This allows the rear side of the pressure plate to fit tightly against the surface of the sealing ring bonded to the front side of the insertion plate, enabling the pressure plate and insertion plate to quickly assemble multiple sets of air ducts. This eliminates the need for multiple sets of bolts and nuts to be screwed together at the through holes of the air duct flange, greatly improving the efficiency of quick assembly and disassembly of multiple sets of air ducts.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] like Figures 1-11As shown, this utility model provides a textile flame-retardant hollow energy-saving air duct, including a fabric strip 2; a sling 3 is sewn to the upper side of the fabric strip 2, and an outer tube fabric 1 is sewn to the lower side of the fabric strip 2; an insert plate 11 is glued to the outer side of the outer tube fabric 1 near the front end, a sealing ring 10 is glued to the front side of the insert plate 11, a pressure plate 7 is glued to the outer side of the outer tube fabric 1 near the rear end, a heat insulation sleeve 12 is nested inside the outer side of the outer tube fabric 1, and a plastic film 13 is glued to the inner side of the heat insulation sleeve 12; an insert plate 11 is glued to the inner side of the plastic film 13 near the front end, a connecting cylinder 4 is rotatably connected to the outer side of the insert plate 11, a handrail bracket 5 is welded to the rear end of the connecting cylinder 4, and a pressure plate 7 is glued to the inner side of the plastic film 13 near the rear end.

[0027] In this embodiment, the heat insulation sleeve 12 is a cylindrical structure that runs through the front and back. The cylindrical structure of the heat insulation sleeve 12 is made of flexible aerogel. By utilizing the nanoporous structure of the flexible aerogel and its own low thermal conductivity, the heat conduction path on the heat insulation sleeve 12 is greatly reduced. This hinders the outward propagation of air heat at the heat insulation sleeve 12, effectively isolating heat transfer and ensuring that the heat of the hot air flows normally inside the heat insulation sleeve 12 with the airflow, thereby reducing temperature loss during the hot air transport process.

[0028] In this embodiment, the outer tube 1 is a tube structure that runs through the front and back. The outer tube 1 covers the outer side of the insulation sleeve 12. The outer tube 1 is made of aramid fiber. Since the limiting oxygen index of aramid fiber itself is 28%, which is much higher than the oxygen content of 21% in the air, the outer tube 1 made of aramid fiber cannot burn in the air in a fire environment and has good self-extinguishing performance, thus preventing open flames from spreading along the layout path of the air duct.

[0029] In this embodiment, the pressure plate 7 is made entirely of flame-retardant plastic. A through hole is located at the center of the pressure plate 7. Six sets of circular grooves are located on the rear side of the pressure plate 7, arranged in a circular array around the horizontal central axis of the through hole in the center of the circular grooves. A threaded structure is located on the outer side of the pressure plate 7 near the rear end. A ring plate structure is located on the outer side of the pressure plate 7 near the middle. A hanging plate 8 is located at the top of the outer side of the ring plate of the pressure plate 7. A circular through hole is located on the front side of the hanging plate 8, facilitating the use of a hanging rope to lift the pressure plate 7 and hang it on the ceiling of the workshop. A sealing gasket 6, made of silicone, is adhered to the rear side of the ring plate of the pressure plate 7. When the pressure plate 7 and the insert plate 11 are mated together, the sealing gasket 6 adheres to the front end of the assembly tube 4. The sealing gasket 6, together with the sealing ring 10, provides double sealing to the assembly part of the pressure plate 7 and the insert plate 11, improving the sealing connection performance between multiple sets of air ducts.

[0030] In this embodiment, the insertion plate 11 has a through hole at its center, and six sets of directional insertion rods 9 are welded to the front side of the insertion plate 11. Each set of directional insertion rods 9 is a cylindrical structure. The six sets of directional insertion rods 9 are arranged in a ring array around the through hole of the insertion plate 11. When the pressure plate 7 is assembled with the insertion plate 11, the directional insertion rods 9 of the insertion plate 11 are inserted into the circular groove on the rear side of the pressure plate 7. The circular groove of the pressure plate 7 provides directional support for the insertion plate 11 through the directional insertion rods 9, ensuring that after the threads of the assembly cylinder 4 and the threads of the pressure plate 7 are engaged, the assembly cylinder 4 drives the pressure plate 7 to move horizontally back and forth along the directional insertion rods 9.

[0031] In this embodiment, the connecting cylinder 4 is a cylindrical structure that runs through the front and rear. The inner side of the connecting cylinder 4 near the front end is provided with a threaded structure. The threaded connection of the connecting cylinder 4 is engaged with the threaded structure on the outer side of the pressure plate 7. During the rotation of the connecting cylinder 4 driven by the handrail rotating frame 5, the connecting cylinder 4 drives the pressure plate 7 to move backward along the directional insertion rod 9 through the thread until the rear side of the pressure plate 7 presses against the sealing ring 10 bonded to the front side of the insertion plate 11. The sealing ring 10 seals the front and rear mating surfaces of the insertion plate 11 and the pressure plate 7, completing the assembly work of tightly mating the pressure plate 7 and the insertion plate 11.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In this invention, when assembling two sets of textile ducts, the threaded rear end of the outer side of the pressure plate 7 is first aligned with the threaded front end of the inner side of the assembly cylinder 4. At this time, the front ends of the six sets of directional inserts 9 welded to the front side of the insert plate 11 are inserted into the six sets of circular grooves in the pressure plate 7. The threaded rear end of the outer side of the pressure plate 7 meshes with the threaded front end of the inner side of the assembly cylinder 4. Then, the handrail rotating frame 5 is manually rotated. Because the thread on the outer side of the pressure plate 7 meshes with the threaded structure on the inner side of the assembly cylinder 4, the handrail rotating frame 5 drives the welded assembly cylinder 4 to rotate. The assembly cylinder 4 then drives the pressure plate 7 to move backward along the directional inserts 9 until the rear side of the pressure plate 7 is in contact with the threaded structure of the inner side of the assembly cylinder 4. The sealing ring 10 is bonded to the front side of the insert plate 11. The sealing ring 10 seals and fits the rear side of the pressure plate 7 and the front side of the insert plate 11, thereby completing the quick sealing and assembly of the pressure plate 7 and the insert plate 11 to form a textile duct consisting of two sets of outer tube fabric 1 and insulation sleeve 12. If it is necessary to disassemble and separate the two sets of textile ducts, manually rotate the handle frame 5 in the opposite direction. The handle frame 5 drives the assembly cylinder 4 to rotate in the opposite direction on the outer side of the insert plate 11. At this time, the assembly cylinder 4 drives the pressure plate 7 to move forward along the directional insert rod 9 until the threads on the outer side of the pressure plate 7 are completely disengaged from the threads on the inner side of the assembly cylinder 4, thereby completing the quick separation of the two sets of textile ducts.

[0034] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies, and any method that achieves the desired effect can be implemented. The sealing gaskets 6, sealing rubber rings 10, and plastic sheeting 13 used above are all common commercially available components. When purchasing and using them, simply follow the instruction manual purchased with the product to connect them for use; therefore, further details are omitted here.

[0035] The technical solution of this utility model is not limited to the scope of the embodiments of this utility model. All technical contents not described in detail in this utility model are known technologies.
