Description
Technical Field
[0001] The utility model relates to the technical field of cloth bag air ducts, in particular to a fiber cloth bag air duct. Background Art
[0002] The bag duct is a flexible air distribution system woven from special fibers. It is an air delivery terminal system that replaces traditional air supply ducts, air valves, diffusers, insulating materials, etc. It can evenly deliver air mainly by relying on the unique air outlet mode of fiber penetration and nozzle jet. The patent application with the prior art announcement number CN218634980U discloses a fiber bag duct, which is convenient for replacing the bag duct parts without replacing the entire bag duct. However, when disassembling, installing and replacing one section of the bag duct, the bag duct is fitted with a fixing ring with an iron ring and embedded in the fixed tube for installation. In order to facilitate the smooth embedding of the fixing ring into the fixed tube, the iron ring inside the fixing ring is often distorted. After embedding, the iron ring is difficult to completely recover, affecting the original fit between the fixing ring and the fixed tube, which in turn leads to poor air tightness between multiple sections of bag ducts, and the practical performance needs to be strengthened. Utility Model Content
[0003] The purpose of the utility model is to provide a fiber bag air duct to solve the problem proposed in the above-mentioned background technology that when a section of the bag air duct is disassembled, installed and replaced, a fixing ring with an iron ring is set on the bag air duct and embedded into a fixing tube for installation. In order to facilitate the smooth embedding of the fixing ring into the fixing tube, the iron ring inside the fixing ring is often twisted and deformed, and the iron ring is difficult to completely restore after embedding, which affects the original fit between the fixing ring and the fixing tube, and then leads to poor air tightness between the multiple sections of bag air ducts, and the practical performance needs to be improved.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fiber bag air duct, comprising a fixing ring, a bag air duct piece is arranged between the plurality of the fixing rings, the bag air duct piece is connected to the fixing ring through a connecting unit, the front and rear ends of the outer wall of the fixing ring are fixedly connected with a suspension rope, the connecting unit comprises a groove cylinder, a cavity ring, a rubber sleeve, a first vertical pipe, a valve, a joint and a transverse cylinder, the transverse cylinder is located between two bag air duct pieces, the outer wall of the transverse cylinder is fixedly sleeved with a rubber sleeve at both ends, the outer wall of the rubber sleeve is tightly abutted against the inner wall of the bag air duct piece, the outer wall of the transverse cylinder is sleeved with groove cylinders on both sides, the inner wall of the groove cylinder is fixedly connected with a cavity ring, the cavity ring is tightly abutted against the outer wall of the bag air duct piece, the top end of the outer wall of the groove cylinder is fixedly connected with a first vertical pipe, the top end of the first vertical pipe is fixedly connected with a valve, and the outer end of the valve is fixedly connected with a joint.
[0005] Preferably, both upper and lower ends of the outer wall of the transverse cylinder are transversely fixed with sliding bars, and the sliding bars are slidably connected to the groove cylinder through sliding grooves.
[0006] Preferably, an auxiliary unit is provided below the groove drum, and the auxiliary unit includes a second vertical pipe, a cavity bag and a hoop sleeve. The second vertical pipe is fixedly connected to the bottom end of the outer wall of the groove drum, and a cavity bag is sleeved below the outer wall of the second vertical pipe. The cavity bag is connected to the second vertical pipe through the hoop sleeve.
[0007] Compared with the prior art, the utility model has the following advantages:
[0008] Through the cooperation among the fixing ring, the bag air duct fitting, the connecting unit and the hanging rope, when a single bag air duct fitting is damaged during long-term use, the maintenance personnel will open and close the valves on both sides of the damaged bag air duct fitting. At this time, the high-pressure air inside the cavity ring is discharged, the air pressure inside the cavity ring is reduced and the volume shrinks, and the inner wall of the cavity ring is separated from the outer wall of the bag air duct fitting. At this time, the damaged bag air duct fitting can be disassembled and replaced with a new one. After replacement, the two ends of the bag air duct fitting are respectively inserted into the disassembled groove barrel, and then the air supply pipe is used to connect with the joint, and high-pressure air is injected into the cavity ring. The volume of the cavity ring expands, and the bag air duct fitting inserted into the inner part of the groove barrel is fully and tightly pressed without blind spots. The bag air duct fitting, the rubber sleeve and the cavity ring are fully fitted and pressed. The operation is simple and convenient, and the air tightness of the bag air duct fitting after replacement and installation can be guaranteed, and the practical performance is enhanced.
[0009] Through the cooperation between the fixed ring, the cloth bag air duct fitting, the connecting unit and the auxiliary unit, part of the high-pressure air inside the cavity ring will be injected into the interior of the cavity bag through the second vertical pipe. The air pressure in the cavity bag is the same as the air pressure inside the cavity ring. External staff can more intuitively know the pressing force of the cavity ring on the outer wall of the cloth bag air duct fitting by observing the volume expansion of the cavity bag.

[0019] See also Figure 1-6The utility model provides a technical solution: a fiber bag air duct, including a fixing ring 1, a bag air duct member 2 is arranged between multiple fixing rings 1, the bag air duct member 2 is connected to the fixing ring 1 through a connecting unit 3, and the front and rear ends of the outer wall of the fixing ring 1 are fixedly connected with a hanging rope 4, and the connecting unit 3 includes a groove cylinder 301, a cavity ring 302, a rubber sleeve 303, a first vertical pipe 304, a valve 305, a joint 306 and a horizontal cylinder 307, and the horizontal cylinder 307 is located Between the two bag air duct parts 2, the horizontal cylinder 307 is connected to the interior of the bag air duct part 2. Both ends of the outer wall of the horizontal cylinder 307 are fixedly sleeved with rubber sleeves 303. The rubber sleeve 303, the cavity ring 302 and the cavity bag 502 are all made of rubber material and have a certain flexibility. The outer wall of the rubber sleeve 303 is tightly pressed against the inner wall of the bag air duct part 2.

The inner wall of the groove cylinder 301 is tightly pressed against the outer wall of the horizontal cylinder 307. The wall gap is matched, and a cavity ring 302 is fixedly connected to the inner wall of the groove cylinder 301. After the high-pressure air is injected into the cavity ring 302, the volume will expand, and the volume will shrink when the high-pressure air in the cavity ring 302 is discharged. The cavity ring 302 is tightly pressed against the outer wall of the cloth bag air duct 2, and a first vertical pipe 304 is fixedly connected to the top of the outer wall of the groove cylinder 301. The first vertical pipe 304 is connected to the interior of the cavity ring 302, and a valve 305 is fixedly connected to the top of the first vertical pipe 304. The outer end of the valve 305 is fixedly connected to a joint 306, and the joint 306 can be used to connect with an external high-pressure air injection hose.

The volume of the cavity ring 302 expands, and the bag air duct fitting 2 inserted into the inner part of the groove cylinder 301 is fully tightened without blind spots. At this time, the valve 305 is closed again, and the external air supply pipe connected to the top of the joint 306 is unplugged. The replacement operation of the damaged bag air duct fitting 2 can be completed, instead of replacing all the bag air duct fittings 2. The operation is simple and convenient, and the air tightness of the bag air duct fitting 2 after replacement and installation can be guaranteed, and the practical performance is enhanced.
