Description

Technical Field

[0001] This application relates to the field of fiber duct technology, and in particular to a heat-insulating and air-guiding fiber duct. Background Technology

[0002] In large-space heating, industrial drying, or agricultural greenhouses, it is often necessary to efficiently and evenly deliver hot air to specific areas. Fiber ducts are increasingly favored in such applications due to their lightweight, gentle airflow, and ease of installation. They typically consist of a fan, a heating unit, and multiple sections of fiber ductwork connected together, achieving diffused air delivery through micropores in the ductwork.

[0003] However, existing fiber duct systems still suffer from several issues affecting their performance and reliability in practical applications. Firstly, the connections between ducts often rely on simple splicing and binding methods, resulting in generally weak connections and poor sealing. Under prolonged use or under certain wind pressure, these connections are prone to loosening and air leakage. This not only leads to heat loss and reduced airflow efficiency but can also cause duct swaying due to unstable connections, generating noise and even safety hazards. Secondly, the air intake filter of the heating unit, the "heart" of the system, is easily clogged by dust and lint accumulated in the environment, leading to reduced airflow, increased fan load, and decreased heating efficiency. Traditional filter cleaning requires shutdown and manual disassembly, a cumbersome process that is difficult to maintain at heights or in inaccessible locations, impacting continuous system operation and ease of use. Especially when the duct system experiences slight deformation or vibration due to unstable connections, it can further exacerbate the instability of the unit's operating environment, making maintenance issues even more prominent. Therefore, this paper proposes a heat-insulating and air-guiding fiber duct to address the technical problem of poor airflow and heat insulation in existing fiber ducts. Summary of the Invention

[0004] The purpose of this invention is to provide a heat-insulating and air-guiding fiber duct to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a heat-insulating and air-guiding fiber duct, comprising a warm air assembly, wherein the warm air assembly comprises a warm air box for generating hot air, wherein a plurality of spliced ​​fiber ducts are provided at one end of the warm air box, wherein fastening components are provided between the fiber ducts, and suspension devices are provided at both ends of the fastening components.

[0006] According to the above technical solution, the two ends of the warm air box are provided with through holes and filter plates are welded and fixed thereon. A rotating shaft is rotatably installed between the two filter plates. A scraper is welded and fixed to one end of the rotating shaft near the filter plate. The scraper is in contact with the surface of the filter plate.

[0007] One of the filter plates has a motor welded and fixed to the end away from the rotating shaft, and the output shaft of the motor passes through the filter plate and is fixedly installed with the rotating shaft.

[0008] According to the above technical solution, a heating element for heating air is welded and fixed to the bottom of the inside of the warm air box; The warm air box has a through hole at one end near the fiber duct, and a drive fan is welded and fixed to the inner wall of the through hole to blow the air in the warm air box into the fiber duct.

[0009] A fixed duct is welded and fixed to the outer wall of the end of the warm air box near the drive fan. A clamp is provided at the end of the fixed duct away from the drive fan. The clamp is used to connect the fixed duct to the fiber duct.

[0010] According to the above technical solution, the inner wall of the fiber duct is welded and fixed with a number of support rings that support the shape of the fiber duct. The inner wall of the fiber duct at the bend is welded and fixed with a guide fan to direct the airflow.

[0011] The fiber duct is nested with an insulation sleeve, and a Velcro fastener for fixing the insulation sleeve is provided between the insulation sleeve and the outer wall of the fiber duct.

[0012] The outer wall of the fiber duct is welded and fixed with suspension rings at intervals. The outer wall of the suspension ring is welded and fixed with a first suspension lug symmetrical about the fiber duct. The first suspension lug has a through hole, and a suspension device is snapped into the through hole.

[0013] According to the above technical solution, the fastening assembly includes fixing rings that are welded and fixed to one end of two fiber duct sections respectively. The two fixing rings are fixed by several bolts. The outer walls of the fixing rings are respectively welded and fixed with second and third suspension ears symmetrical about the fiber duct. The second suspension ear on the same side is located between the two third suspension ears. The top ends of the second and third suspension ears are provided with coaxial through holes. The suspension device includes a suspension hook that is snapped into a through hole. A suspension rope is welded and fixed to the top of the suspension hook.

[0017] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: like Figure 1As shown, a heat-insulating and air-guiding fiber duct includes a warm air assembly 1, which includes a warm air box 101 that generates hot air. A plurality of spliced ​​fiber ducts 2 are provided at one end of the warm air box 101, and fastening components 3 are provided between the fiber ducts 2. Suspension devices 4 are provided at both ends of the fastening components 3.

[0019] like Figure 2 As shown, the warm air box 101 has through holes at both ends and filter plates 104 are welded and fixed thereon. A rotating shaft 105 is rotatably installed between the two filter plates 104. A scraper 106 is welded and fixed to one end of the rotating shaft 105 near the filter plate 104. The scraper 106 is in contact with the surface of the filter plate 104. One of the filter plates 104 is welded and fixed to a motor 107 at the end away from the rotating shaft 105. The output shaft of the motor 107 passes through the filter plate 104 and is fixedly installed with the rotating shaft 105.

[0020] When the heater box 101 has been running for a period of time, dust may accumulate on the surface of the filter plate 104, affecting ventilation. The motor 107 can then be started. The output shaft of the motor 107 drives the rotating shaft 105 to rotate, and the scraper plates 106 fixed at both ends of the rotating shaft 105 rotate synchronously. Since the scraper plates 106 always remain in contact with the inner surface of the filter plate 104, they can scrape off the dust adhering to the filter plate 104 during rotation, causing the dust to fall off and be collected or discharged. This process does not require disassembling the filter plate 104, achieving online automatic cleaning of the filter plate 104, thereby maintaining a consistently unobstructed air intake channel and ensuring the air intake efficiency of the heater box 101 and the continuous stable operation of the system.

[0021] like Figure 2 As shown, a heating element 103 for heating air is welded and fixed to the bottom of the interior of the warm air box 101; The warm air box 101 has a through hole at one end near the fiber duct 2, and a drive fan 102 is welded and fixed to the inner wall of the through hole to blow the air in the warm air box 101 into the fiber duct 2.

[0022] A fixed duct 108 is welded and fixed to the outer wall of the end of the warm air box 101 near the drive fan 102. A clamp 109 is provided at the end of the fixed duct 108 away from the drive fan 102. The clamp 109 is used to connect the fixed duct 108 and the fiber duct 2.

[0023] When the system starts, the heating element 103 at the bottom of the warm air box 101 operates first, uniformly and stably heating the air inside the box. Subsequently, the drive fan 102 located at the outlet end of the box operates, generating strong suction and airflow to continuously draw the heated air out of the warm air box 101. The hot air is guided out through the fixed duct 108 welded to the box, and is securely and sealed to the inlet end of the fiber duct 2 through the clamp 109 at its end, thereby efficiently and leak-free delivering the hot air to the entire interior of the fiber duct 2.

[0024] like Figure 4 and Figure 5 As shown, a plurality of support rings 201 supporting the shape of the fiber duct 2 are welded and fixed to the inner wall of the fiber duct 2. The inner wall of the bend of the fiber duct 2 is welded and fixed with a guide fan 204 to guide the airflow.

[0025] The fiber duct 2 is nested with an insulation sleeve 203, and a Velcro 202 for fixing the insulation sleeve 203 is provided between the insulation sleeve 203 and the outer wall of the fiber duct 2.

[0026] The outer wall of the fiber duct 2 is welded and fixed with suspension rings 205 at intervals. The outer wall of the suspension rings 205 is welded and fixed with first suspension ears 206 symmetrical about the fiber duct 2. The first suspension ears 206 have through holes, and the suspension device 4 is snapped into the through holes.

[0027] When hot air from the warm air box 101 is delivered into the fiber duct 2 via the fixed duct 108, the circular cross-section of the duct is first maintained by the evenly distributed support rings 201 on the inner wall, preventing deformation or collapse under wind pressure and ensuring stable and unobstructed airflow. When the airflow passes through the bend in the duct, the pre-installed air guide fan 204 on the inner wall starts, and the auxiliary airflow it generates actively guides the main airflow to a smooth turn, significantly reducing eddies and local resistance, and ensuring air delivery efficiency and wind speed. At the same time, the insulation sleeve 203 wrapped around the outer wall of the duct is tightly attached by Velcro 202, effectively blocking heat exchange and reducing heat loss during long-distance transportation. The entire duct is suspended by suspension rings 205 spaced apart on the outer wall and first suspension lugs 206 symmetrically distributed on them.

[0028] like Figure 3 As shown, the fastening assembly 3 includes a fixing ring 301 that is welded and fixed to one end of two fiber ducts 2 that are close to each other. The two fixing rings 301 are fixed by a number of bolts 302. The outer wall of the fixing rings 301 is welded and fixed with a second suspension lug 303 and a third suspension lug 304 that are symmetrical about the fiber duct 2. The second suspension lug 303 on the same side is located between the two third suspension lugs 304. The top ends of the second suspension lug 303 and the third suspension lug 304 are provided with coaxial through holes. The suspension device 4 includes a suspension hook 401 that is snapped into a through hole. A suspension rope 402 is welded and fixed to the top of the suspension hook 401. The end of the suspension rope 402 away from the suspension hook 401 is movably installed on a fixed track for suspending the fiber duct 2.

[0029] When two independent fiber duct sections 2 need to be extended and spliced, the fixing rings 301, which are respectively fixed to the ends of the two duct sections, are first aligned and fitted together. Then, several bolts 302 are passed through the preset holes and tightened, thereby firmly and sealingly connecting the two duct sections into a whole, ensuring that there is no air leakage or loosening at the connection. At the same time, the second suspension lug 303 and the third suspension lug 304 installed on the outer wall of the fixing ring 301 together form a reinforced suspension node. Among them, the second suspension lug 303 in the middle and the third suspension lug 304 on both sides have coaxial through holes at their top ends. This design allows the suspension hook 401 of the suspension device 4 to pass through these three lug holes at the same time, thus making the connection point itself a stable and reliable load-bearing suspension point. This structure not only realizes the rapid and rigid connection of the duct sections, but also directly transfers the stress point to the sturdy fixing ring 301, effectively avoiding deformation or stress concentration at the connection due to additional load, and greatly enhancing the integrity and stability of the long-distance duct system in the suspended state.

[0030] Working principle: When this insulated and air-guided fiber duct is in operation, the heating element 103 inside the warm air box 101 is activated first to heat the air. Then, the drive fan 102 operates, drawing the hot air generated inside the warm air box 101 and delivering it into the first section of the fiber duct 2 through the connection of the fixed duct 108 and the clamp 109. The hot air is transported inside the fiber duct 2, its tubular shape maintained by the support ring 201 on the inner wall. When the duct path needs to change direction, the air guide fan 204 installed on the inner wall at the bend is activated to guide the airflow and reduce wind resistance and energy loss.

[0031] To accommodate air supply requirements of varying lengths, multi-section fiber ducts 2 can be spliced ​​together using fastening components 3. During splicing, the fixing rings 301 at the ends of two duct sections are aligned and fastened together using bolts 302. The entire duct system is installed on a fixed track using a suspension device 4. Suspension hooks 401 pass through the through holes in the first suspension lug 206 on the outer wall of the fiber duct or the second suspension lug 303 and third suspension lug 304 on the fastening components, and are suspended by suspension ropes 402, achieving stable duct installation and flexible pipeline layout. Furthermore, the insulation sleeve 203 wrapped around the outside of the fiber duct 2 is secured with Velcro 202, effectively reducing heat loss from the pipeline.

[0032] During the operation of the warm air box 101, air enters through the filter plates 104 at both ends. To keep the filter plates unobstructed, the motor 107 can be started to drive the rotating shaft 105 and the scraper 106 on it to rotate, thereby scraping away the dust and impurities attached to the surface of the filter plates 104, ensuring smooth air intake and efficient heat exchange.
