Description

Technical Field

[0001] This utility model relates to the field of fiber collection equipment technology, and in particular to a fiber collection bin with a slow-flow settling structure. Background Technology

[0002] Fiber collection bins are key pieces of equipment widely used in industrial production processes such as textiles, composite materials, and waste recycling. Their main function is to collect, store, and transfer loose fibers, such as cotton fibers, chemical fibers, or glass fibers, generated during the production process.

[0003] In conventional fiber collection operations, fiber materials typically enter from the top of the silo and settle naturally to the discharge port at the bottom under their own weight. However, fiber materials have physical characteristics such as low density, light weight, loose texture, and a tendency to entangle themselves due to static electricity or humidity.

[0004] Due to this characteristic, during free settling, the fibers fall at a relatively high speed, easily tumbling and aggregating in the air to form irregular fiber clumps. When these fiber clumps collide with the inner wall of the chamber, especially in the conical contraction section at the bottom of the chamber, they adhere to the wall surface due to the impact of speed and friction, squeezing and overlapping each other to form bridging and clumping phenomena.

[0005] Once this adhesion, clumping, and bridging phenomenon occurs, it not only severely blocks the discharge channel at the bottom of the silo, preventing fibers from being discharged smoothly and causing production interruptions, but also requires manual intervention for cleaning, increasing labor intensity and posing safety hazards. More seriously, this unstable settling process significantly reduces the overall collection efficiency, failing to meet the requirements of modern, high-efficiency production.

[0006] Therefore, this invention proposes a fiber collection bin with a slow-flow settling structure to address the shortcomings of existing technologies. Utility Model Content

[0007] To overcome the above deficiencies, this utility model provides a fiber collection bin with a slow-flow settling structure, which aims to improve the problem in the prior art where fibers tend to pile up and stick together due to excessively fast settling speed during the collection process, leading to blockage of the bin and affecting the stable operation of the equipment.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a fiber collection bin with a slow-flow settling structure, comprising: a bin body, an inlet pipe, an outlet box, a feed pipe, and a first outlet pipe, wherein the inlet pipe is connected to the top of the bin body, the outlet box is disposed below the bin body, the upper end of the feed pipe is connected to the bottom of the bin body, and the lower end of the feed pipe is connected to the top of the outlet box, and the first outlet pipe is connected to the outlet box, characterized in that it further comprises an anti-adhesion component and a negative suction component, wherein the anti-adhesion component is disposed inside the bin body; The anti-adhesion assembly includes a guide plate, a nozzle, an air supply pipe, and a fixing ring. The guide plate is fixedly connected to the inner wall of the chamber and is an annular sliding plate extending downward along the inner wall of the chamber. The nozzle is located below the guide plate. One end of the air supply pipe passes through the inner wall of the chamber and is fixedly connected to the nozzle. The fixing ring is fixed to the inner wall of the chamber and surrounds and clamps the nozzle.

[0009] Preferably, the negative suction assembly includes a re-suction cylinder, a second discharge pipe, a re-suction tube, and a base. One end of the re-suction tube is connected to the bottom of the discharge box, and the other end is connected to the re-suction cylinder. The second discharge pipe is connected to the side wall of the re-suction cylinder, and the base is fixedly connected to the bottom of the re-suction cylinder.

[0010] Preferably, the end of the air supply pipe is fixedly connected to the central air inlet of the nozzle.

[0011] Preferably, the inner ring of the fixing ring abuts against the outer periphery of the nozzle, and its outer ring is welded and fixed to the inner wall of the chamber.

[0012] Preferably, the port where the re-suction pipe communicates with the discharge box is located in the bottom corner of the discharge box.

[0013] Preferably, the base is a flat plate, and the flat plate has mounting holes for fixing to the ground.

[0014] Preferably, an observation window is provided on the side wall of the compartment.

[0015] Preferably, the inlet pipe is vertically positioned at the top center of the chamber.

[0016] This utility model has the following beneficial effects: 1. In this utility model, by setting an anti-adhesion component consisting of a guide plate and nozzles inside the silo, the problem in the prior art that fibers are prone to stacking and sticking together due to excessively fast settling speed during the collection process, which leads to silo blockage and affects the stable operation of the equipment is solved. This achieves the effect of effectively slowing down and blowing away the falling fibers, ensuring smooth flow, avoiding a decrease in settling efficiency, and significantly improving the stability and reliability of equipment operation. 2. This utility model solves the problem in the prior art that fiber residue is easily generated in the dead corner area of ​​the discharge box, which is difficult to clean completely, resulting in incomplete fiber recovery and affecting the recovery efficiency, by setting a negative suction component consisting of a re-suction pipe and a re-suction cylinder at the discharge box. It achieves forced and targeted removal of residual fibers in the dead corner of the discharge box, realizes complete fiber recovery, effectively reduces edge residue, and ensures fiber recovery efficiency and the cleanliness of subsequent equipment operation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1 - Figure 4This utility model provides a fiber collection bin with a slow-flow settling structure, which aims to solve the problems of adhesion, agglomeration and blockage caused by the direct and rapid settling of materials in existing fiber collection technologies, as well as the difficulty in removing fiber residues in the dead corners of the discharge port.

[0021] Specifically, the device includes a silo body 1, an inlet pipe 2, an outlet box 3, an inlet pipe 7, and a first outlet pipe 6. The silo body 1 serves as the main structure of the entire device and is used to contain and process fibers. The inlet pipe 2 is connected to the top of the silo body 1 and is used to guide external fiber materials into the interior of the silo body 1. The outlet box 3 is located below the silo body 1 and is used to collect fibers that have settled down from the silo body 1. The upper end of the inlet pipe 7 is connected to the bottom of the silo body 1, and the lower end of the inlet pipe 7 is connected to the top of the outlet box 3, forming a material channel connecting the silo body 1 and the outlet box 3. The first outlet pipe 6 is connected to the outlet box 3 and serves as the main material outlet, used to discharge the collected fibers to the next process.

[0022] It also includes an anti-adhesion component 4 and a negative suction component 8. The anti-adhesion component 4 works with the chamber 1 to achieve slow-flow sedimentation of fibers and prevent clogging. The negative suction component 8 works with the discharge box 3 to remove residual fibers. The anti-adhesion component 4 is located inside the chamber 1, specifically in the conical contraction area below the chamber 1. The anti-adhesion component 4 includes a guide plate 401, a nozzle 402, an air supply pipe 403, and a fixing ring 404. The guide plate 401 is fixedly connected to the inner wall of the chamber 1. The guide plate 401 is an annular sliding plate that extends downwards along the inner wall of the chamber 1. After the fibers fall from the inlet pipe 2, they first come into contact with the inclined plate. The fiber slides down the surface of the guide plate 401, which increases the movement path of the fiber and creates a buffer, thus achieving initial deceleration of the fiber. The nozzle 402 is located below the guide plate 401 and in the central area of ​​the chamber 1. One end of the air supply pipe 403 passes through the wall of the chamber 1 and is fixedly connected to the nozzle 402. It is used to deliver compressed gas from an external air source to the nozzle 402. The fixing ring 404 is fixed to the inner wall of the chamber 1 and surrounds and clamps the nozzle 402, which plays a role in radial limiting and axial fixing of the nozzle 402, ensuring that the nozzle 402 remains stable under the impact of airflow.

[0023] The negative suction assembly 8 includes a re-suction cylinder 801, a second discharge pipe 802, a re-suction tube 803, and a base 804. The re-suction cylinder 801 serves as a container for temporarily storing the suctioned fibers. One end of the re-suction tube 803 is connected to the bottom of the discharge box 3, and the other end is connected to the re-suction cylinder 801, forming a channel for suctioning out residual fibers. The second discharge pipe 802 is connected to the side wall of the re-suction cylinder 801 and is used to discharge the fibers inside the re-suction cylinder 801. The base 804 is fixedly connected to the bottom of the re-suction cylinder 801, providing stable ground support for the entire negative suction assembly 8.

[0024] To facilitate real-time monitoring of the settling and flow of fibers inside chamber 1, and to enable internal inspection and maintenance when necessary, an observation window 5 is provided on the side wall of chamber 1. The observation window 5 is preferably made of a high-strength, pressure-resistant transparent material, such as tempered glass or polycarbonate sheet, to ensure structural integrity and clear visibility even under the pressure environment of equipment operation. The edge of the observation window 5 is sealed and fixed to the opening of chamber 1 by a sealing ring, for example, by using a flange and bolt fastening method, and is equipped with a corrosion-resistant rubber or silicone sealing gasket to prevent gas or fiber leakage inside chamber 1, and also to prevent external impurities from entering. Through the observation window 5, operators can intuitively judge the working effect of the anti-adhesion component 4, check for the initial signs of fiber accumulation or agglomeration, and thus adjust the air volume of the air supply pipe 403 in a timely manner or take other intervention measures to avoid the occurrence and deterioration of blockage problems. This visualized structural design improves the operability and maintainability of the equipment.

[0025] To ensure that the fiber material can be evenly distributed on the cross-section of the silo 1 and achieve a more ideal initial settling state, the feed pipe 2 is vertically set at the top center of the silo 1. This centrally symmetrical layout allows the fibers entering from the feed pipe 2 to spread naturally in all directions with the central axis of the silo 1 as the reference, avoiding the situation where there is too much material on one side and too little material on the other side due to eccentric feeding. This reduces the workload of the subsequent anti-adhesion component 4 in uniformly dispersing the material. The inlet of the feed pipe 2 can be further designed with a flared shape to facilitate the initial diffusion of the fiber bundles at the moment of entering the silo 1. This centrally vertical arrangement also simplifies the structural design and pipe layout of the top of the silo 1, ensuring the symmetry and predictability of the material flow.

[0026] To maximize airflow utilization efficiency and jetting effect, the end of the air supply pipe 403 is fixedly connected to the central air inlet of the nozzle 402. The nozzle 402 is typically designed with a structure having multiple jet holes facing different directions, such as upward or radially distributed. Introducing airflow from the center ensures that the gas pressure is evenly distributed to each jet hole, thereby forming a stable and symmetrical blowing air field. This connection method can be achieved by threaded connection or flange connection to ensure the connection's firmness and airtightness. The central air inlet design avoids the problems of airflow deviation and uneven pressure distribution inside the nozzle 402 caused by side air inlet, ensuring that the nozzle 402 can generate a uniform lifting and blowing force from bottom to top on the falling fiber clumps, effectively preventing the fibers from accumulating and clumping in the cone area at the bottom of the chamber 1, and ensuring a smooth settling process.

[0027] The inner ring of the fixing ring 404 abuts against the outer circumference of the nozzle 402, and the outer ring of the fixing ring 404 is welded to the inner wall of the chamber 1. The fixing ring 404 itself can be a metal ring with its inner diameter precisely matched with the outer diameter of the nozzle 402. The nozzle 402 is radially limited by abutting, preventing the nozzle 402 from shaking or displacing under the impact of airflow. The outer ring of the fixing ring 404 is directly welded to the inner wall of the chamber 1 to form a permanent and firm connection that can resist vibration and fatigue caused by long-term operation. Compared with detachable connections such as bolts, welding avoids the potential risks caused by bolt loosening and ensures the long-term stability of the core component position of the anti-adhesion component 4. This is crucial for maintaining a stable blowing air field. This structure is simple and robust, with low manufacturing cost and high reliability.

[0028] To most effectively remove residual fibers, the port connecting the re-suction pipe 803 to the discharge box 3 is located in the bottom corner of the discharge box 3. In the discharge box 3, due to the influence of material flow and the geometry of the box, areas with extremely low flow velocity, i.e., flow dead corners, are easily formed in the corners far from the first discharge pipe 6, especially at the bottom edge. Lightweight materials such as fibers are prone to sedimentation and accumulation in these areas and cannot be discharged normally with the main material flow. By precisely positioning the suction port of the re-suction pipe 803 in these predicted dead corner positions, the negative pressure generated by the re-suction cylinder 801 can be used to specifically force out these retained fibers, achieving targeted removal of dead corner areas. This completely solves the problem of material residue in the discharge box 3, ensures the cleanliness of the box after each collection task, improves the overall fiber recovery rate, and provides a clean initial environment for the collection of subsequent batches of fibers, avoiding cross-contamination.

[0029] The base 804 is a flat plate with mounting holes for fixing it to the ground. During operation, the re-suction cylinder 801 will vibrate due to the internal airflow. Stable installation is the foundation for its long-term reliable operation. Designing the base 804 as a flat plate with a large contact area can effectively distribute the weight and vibration load of the re-suction cylinder 801 and improve the overall stability. The mounting holes on the flat plate, such as four through holes distributed at the four corners, allow the use of anchor bolts or expansion bolts to firmly fix the entire negative suction assembly 8 to the concrete floor of the workshop. This fixing method ensures that even under strong suction conditions, the negative suction assembly 8 will not shift or tip over, ensuring the safe operation of the equipment. It also ensures the stability of the relative position of the connection between the re-suction pipe 803 and the discharge box 3, preventing the connection from loosening or being damaged due to vibration.

[0030] Working principle: First, the fiber flows into the interior of the chamber 1 through the feed pipe 2. Then, the fiber is slowed down and prevented from clogging by the internal and external anti-adhesion components 4. The internal condition of the chamber 1 can be viewed through the observation window 5. Then, it enters the interior of the discharge box 3 through the feed pipe 7. Finally, it passes through the first discharge pipe 6. The remaining material that cannot flow is sucked out by the negative suction component 8, thus completing the process. During the settling process, the fiber body first slides down through the guide plate 401 for initial deceleration. The guide plate 401 is made of a slippery material. The fiber body then falls into the interior of the chamber 1. Subsequently, the gas is connected to the air supply pipe 403, and the gas in the air supply pipe 403 is delivered to the nozzle 402 to blow air onto the fiber body inside the chamber 1, preventing the fiber body from piling up and causing blockage. The fixing ring 404 fixes the air supply pipe 403 and the nozzle 402 inside the chamber 1. Ultimately, this reduces fiber adhesion, prevents bottom clumping, and clears fibers from blocked areas, ensuring smooth flow, avoiding a decrease in settling efficiency, and stabilizing equipment operation. When the fiber body does not circulate inside the discharge box 3, the re-suction cylinder 801 is activated first, and the precipitated fiber body inside the discharge box 3 is guided into the re-suction cylinder 801 through the re-suction pipe 803. Finally, the fiber body is discharged through the second discharge pipe 802 on one side of the re-suction cylinder 801, completing the process. The re-suction cylinder 801 is set on the ground through the base 804, which can ultimately eliminate fiber residue in the dead corner of the discharge box 3, forcibly clean the residual fiber at the discharge port, reduce edge residue, and ensure fiber recycling efficiency and stable operation of the equipment.
