Description

Technical Field

[0001] The utility model relates to the technical field of ventilation ducts, in particular to a new type of flexible connection fiber fabric bag ventilation duct. Background Technique

[0002] The flexible connection fiber fabric bag ventilation duct is one of the many types of ventilation ducts. Compared with metal ventilation ducts, it is lighter in weight, lower in manufacturing cost, and more labor-saving and time-saving during installation. At the same time, its service life can fully meet the usage requirements. However, the existing flexible connection fiber fabric bag ventilation ducts still have some disadvantages. For example, they cannot be effectively stored and stacked during transportation and handling, which results in taking up a large amount of space during transportation and handling, and is also prone to being bumped and damaged. At the same time, the existing flexible connection fiber fabric bag ventilation ducts do not have the effect of dust filtration. After long-term use, due to the air flow, a large amount of dust will accumulate on the inner wall of the ventilation duct, thus affecting the use effect. Therefore, we propose a new type of flexible connection fiber fabric bag ventilation duct. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1:

[0020] Please refer to Figures 1-3 , the present invention provides a technical solution: a new type of flexible connection fiber fabric bag ventilation duct, including a ventilation duct 1. A fixing ring 2 is sequentially arranged on the outer wall of the ventilation duct 1 from left to right. A left connection end 3 is arranged on the left side of the ventilation duct 1, and a right connection end 4 is arranged on the right side of the ventilation duct 1. Fixing blocks 5 are arranged at the centers of the top and bottom of the left connection end 3 and the right connection end 4. Connection holes are horizontally penetrated through the fixing blocks 5, and fixing bolts can be installed on the connection holes. The left and right sides of the ventilation duct 1 can be connected to another group of ventilation ducts 1 through the left connection end 3 and the right connection end 4. When connecting and fixing, it is connected and installed through the fixing blocks 5. On the right side of the top and bottom of the left connection end 3, left fixing rods 6 are arranged. On the outer sides of the left fixing rods 6, away from the left connection end 3, left clamping blocks 7 are arranged. On the left side of the top and bottom of the right connection end 4, right fixing rods 8 matching the left fixing rods 6 are arranged. On the inner sides of the right fixing rods 8, away from the right connection end 4, right clamping blocks 9 matching the left clamping blocks 7 are arranged. When the overall flexible connection fiber fabric bag ventilation duct is being stored, transported or carried, the left connection end 3 can be moved closer to the right connection end 4, and the ventilation duct 1 can be retracted between the two in this way. When the left connection end 3 and the right connection end 4 are retracted to a certain distance, the left clamping block 7 and the right clamping block 9 will be clamped, which can avoid the phenomenon of loosening and increase the stability during storage. A fiber insulation layer 10 is arranged on the inner wall of the ventilation duct 1, and the fiber insulation layer 10 can play a heat preservation effect. A flame retardant layer 11 is arranged on the inner wall of the fiber insulation layer 10, and the flame retardant layer 11 can play a flame retardant protection effect. An outer fixing ring 14 is arranged in the inner cavity of the left connection end 3, and a filter screen 15 is arranged in the outer fixing ring 14. The arranged filter screen 15 can play a dust filtering effect.

[0021] Among them, preferably, an anti-aging layer 12 is arranged on the outer wall of the ventilation duct 1, and an outer protective wear-resistant layer 13 is arranged on the outer wall of the anti-aging layer 12. The arrangements of the anti-aging layer 12 and the outer protective wear-resistant layer 13 can effectively protect the ventilation duct 1 and thus extend its service life.

[0022] Preferably, connecting blocks 16 are equidistantly arranged around the outer wall of the outer fixing ring 14. Grooves 17 matching the connecting blocks 16 are arranged around the left side of the left connecting end 3. Bolts 18 are arranged between the left side of the connecting block 16 and the right side of the inner cavity of the groove 17. Such a setting can achieve the effect of quickly disassembling and assembling the outer fixing ring 14 through the bolts 18, thereby achieving the effect of quickly disassembling and assembling the filter screen 15, and regularly cleaning the filter screen 15 to avoid dust accumulation.

[0023] Preferably, the filter screen 15 is set as a metal filter screen. The metal filter screen has a long service life and is not prone to deformation. An anti-rust protective layer is evenly sprayed on the surface of the metal filter screen. The provided anti-rust protective layer can effectively protect the metal filter screen and prevent rust on its surface. The filter screen 15 is fixedly welded to the outer fixing ring 14. Through the welding method, the filter screen 15 and the outer fixing ring 14 can be stably connected.

The N poles of the magnets I face outward. On one end of the right clamping block 9 facing the right connecting end 4, mounting grooves II are arranged, and magnets II matching the magnets I are arranged in the mounting grooves II. The S poles of the magnets II face outward. When the left clamping block 7 and the right clamping block 9 are clamped, the magnets I and the magnets II will be adsorbed together through magnetic attraction, thereby increasing the stability when the left clamping block 7 and the right clamping block 9 are clamped; both the left clamping block 7 and the right clamping block 9 are set as right-angled triangular clamping blocks. The left clamping block 7 and the left fixing rod 6 are of an integrally formed structure, and the right clamping block 9 and the right fixing rod 8 are of an integrally formed structure. The integrally formed structure has strong stability and high structural strength and is not prone to breakage; on the left side of the connecting block 16, corresponding to the position of the bolt 18, grooves I are arranged. Such a setting can prevent the head of the bolt 18 from protruding after the bolt 18 is installed in place. After the bolt 18 is installed in place, its bolt head will enter the grooves I. Such a setting can prevent affecting the subsequent installation and connection of the left connecting end 3. The bolts 18 are all set as internal hexagonal bolts. The internal hexagonal bolts are convenient for quick installation and disassembly and have strong connection stability.
