Description

Technical Field

[0001] This utility model relates to the technical field of sulfurized fiber production equipment, and in particular to an aging device for continuous sulfurized fiber production. Background Technology

[0002] After vulcanization and washing, vulcanized fibers need to undergo an aging process to eliminate internal stress, promote chemical structure stabilization, and optimize key indicators such as tensile strength, corrosion resistance, and dimensional stability.

[0003] Traditional devices often use single-sided fans or non-directional airflow designs, resulting in obvious temperature and humidity gradients inside the aging chamber (temperature difference can reach 5-10℃, humidity deviation >10%RH). The sulfurized fibers are heated and humidified unevenly during transportation. Some areas become brittle and lose strength due to excessive aging, while some areas retain internal stress due to insufficient aging. As a result, the pass rate of key product performance (such as tensile strength and corrosion resistance) is less than 85%. Summary of the Invention

[0004] This utility model provides an aging device for continuous production of vulcanized fibers. Through the symmetrical layout of the internal fan and the synergistic effect of the guide slope, a closed-loop circulating airflow is constructed around the conveyor chain in the intermediate aging treatment box. This achieves airflow without dead angles in the intermediate aging treatment box, accelerates the airflow inside the intermediate aging treatment box, improves the consistency of air temperature and humidity inside the intermediate aging treatment box, and effectively eliminates the regional temperature difference and humidity gradient problems of traditional devices.

[0005] This utility model provides an aging device for continuous production of vulcanized fibers, specifically including: a medium aging treatment box, a conveyor chain, and a sealing end plate. The conveyor chain is provided inside the medium aging treatment box, and sealing end plates are fixedly connected to both ends of the medium aging treatment box. An internal fan is fixedly connected to the top and bottom of the medium aging treatment box. An air guide slope is provided at the top and bottom of the inner side of the medium aging treatment box. A heating module is fixedly connected to the middle of the air guide slope. The power of the heating module is adjustable from 1 to 5 kW, and the heating temperature is controlled between 50 and 120°C. A humidifying spray pipe is provided at the top of the inner side of the medium aging treatment box. The humidifying spray pipe is connected to the pump pipeline. The humidifying spray pipe is arranged at intervals of 100 to 200 mm along the conveying direction. The spray volume is adjustable from 0.5 to 2 L / h, achieving precise control of the humidity of the chamber from 30% to 90% RH. An upper exhaust pipe is fixedly connected to the top of the medium aging treatment box. The upper exhaust pipe is used to discharge the waste gas volatilized during the aging process.

[0006] Furthermore, the internal fans inside the intermediate aging treatment chamber are arranged horizontally and symmetrically, and the internal fans and the guide slope are arranged adjacent to each other. Through the symmetrical arrangement of the internal fans and the synergistic effect of the guide slope, a closed-loop circulating airflow around the conveyor chain is constructed inside the intermediate aging treatment chamber.

[0007] Furthermore, the inclined air guide is located on the air outlet side of the inner fan, and the inclined air guide is tilted towards the side away from the inner fan and close to the conveyor chain. The inclined air guide is set at an angle of 15°-45°. Through the inclined air guide, the air outlet of the inner fan forms a closed ring airflow circulation along the upper and lower inner walls of the cavity, so that the temperature deviation of each area of ​​the cavity is ≤±2℃ and the humidity deviation is ≤±5%RH, ensuring that the vulcanized fiber is heated and moistened evenly.

[0008] Furthermore, the inner side of the conveyor chain is rotatably connected to the outer frame via a rotating shaft. The middle of both the conveyor chain and the outer frame is located inside the aging treatment chamber. The conveyor chain is driven by a servo motor to rotate the inner shaft (speed adjustable range 0.5~5m / min) to achieve cyclic rotation, ensuring uniform conveying of the vulcanized fiber.

[0009] Furthermore, the outer frame is spaced apart from the inner walls of the intermediate aging treatment chamber on both sides, with a 50-100mm gap between the outer frame and the inner walls of the intermediate aging treatment chamber, forming a side airflow channel. This, combined with the annular circulating airflow, achieves uniform airflow distribution throughout the chamber, improving the consistency of air temperature and humidity inside the intermediate aging treatment chamber. The conveyor chain has guide slopes and heating modules at both ends, with the humidifying spray pipe positioned above the conveyor chain. The heating module and humidifying spray pipe respectively regulate the temperature and humidity.

[0010] Furthermore, a middle baffle is slidably connected in the vertical direction at the middle part of the sealing end plate, and tightening screws are threaded on both sides of the middle baffle.

[0011] Furthermore, the tightening screw and the sealing end plate are in tight contact, the middle baffle is above the conveyor chain, the inner side of the sealing end plate is in contact with the outer side of the outer frame, and the inner side of the sealing end plate and the outer side of the outer frame are tightly in contact with each other by a sealing strip, with a sealing gap of ≤0.5mm, reducing heat loss from the cavity. The middle baffle slides vertically to adjust its height to adapt to the sealing requirements of different thicknesses of vulcanized fiber. The middle baffle is locked and positioned by the tightening screw.

[0012] This utility model provides an aging device for continuous production of vulcanized fibers, which has the following beneficial effects: By combining the symmetrical layout of the internal fans with the synergistic effect of the inclined air guides, a closed-loop circulating airflow is constructed around the conveyor chain within the intermediate aging treatment chamber. This ensures seamless airflow within the chamber, accelerates air circulation, and improves the uniformity of temperature and humidity. It effectively eliminates the regional temperature difference and humidity gradient problems inherent in traditional devices, preventing uneven heating and humidification of the vulcanized fibers during conveying, which could lead to over-aging (e.g., embrittlement) in some areas and under-aging (e.g., performance not meeting standards) in others.

[0013] The conveyor chain continuously transports the vulcanized fibers into the intermediate aging treatment box for aging operations, forming an integrated continuous process of "feeding-aging-discharging". The vulcanized fibers can complete the continuous aging treatment without intermediate manual intervention, which further improves the processing efficiency. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] Example 1: Please refer to Figures 1 to 6 : This utility model proposes an aging device for continuous production of vulcanized fibers, including an intermediate aging treatment box 1, a conveyor chain 2, and a sealing end plate 3. An internal fan 101 is fixedly connected to both the top and bottom of the intermediate aging treatment box 1. Air guide slopes 102 are provided at the top and bottom of the inner side of the intermediate aging treatment box 1. A heating module 103 is fixedly connected to the middle of the air guide slopes 102. The power of the heating module 103 is adjustable from 1 to 5 kW, and the heating temperature is controlled between 50 and 120℃. A humidifying spray pipe 104 is provided at the top of the inner side of the intermediate aging treatment box 1. The humidifying spray pipes 104 are connected to the pump pipeline. The humidifying spray pipes 104 are arranged at intervals of 100-200mm along the conveying direction, with an adjustable spray volume of 0.5-2L / h, achieving precise control of the chamber humidity from 30% to 90%RH. An upper exhaust pipe 105 is fixedly connected to the top of the intermediate aging treatment chamber 1. The upper exhaust pipe 105 is used to discharge the volatile waste gas generated during the aging process. The internal fans 101 inside the intermediate aging treatment chamber 1 are horizontally symmetrically arranged, with the internal fans 101 and the guide slope 102 arranged adjacent to each other. The symmetrical arrangement of the internal fans 101 and the guide slope... The synergistic effect of 102 creates a closed-loop circulating airflow around the conveyor chain 2 within the intermediate aging treatment chamber 1. The conveyor chain 2 is located inside the intermediate aging treatment chamber 1, and its inner side is rotatably connected to the outer frame 201 via a rotating shaft. The middle parts of both the conveyor chain 2 and the outer frame 201 are located inside the intermediate aging treatment chamber 1. The conveyor chain 2 is driven by a servo motor to rotate its inner shaft in a circular motion, ensuring uniform conveying of the vulcanized fibers. Sealing end plates 3 are fixedly connected to both ends of the intermediate aging treatment chamber 1, and a middle baffle is slidably connected vertically to the middle of the sealing end plates 3. 301, both sides of the middle baffle 301 are threaded with tightening screws 302, which are in tight contact with the sealing end plate 3. The middle baffle 301 is located above the conveyor chain 2. The inner side of the sealing end plate 3 is in contact with the outer side of the outer frame 201. The inner side of the sealing end plate 3 and the outer side of the outer frame 201 are tightly in contact with each other by a sealing strip. The sealing gap is ≤0.5mm to reduce heat loss from the cavity. The height of the middle baffle 301 can be adjusted by sliding in the vertical direction to adapt to the sealing requirements of different thicknesses of vulcanized fiber. The middle baffle 301 is locked and positioned by the tightening screws 302.

[0019] In this embodiment, the air guide slope 102 is located on the air outlet side of the inner fan 101. The air guide slope 102 is inclined away from the inner fan 101 and close to the conveyor chain 2. The air guide slope 102 is set at an inclination angle of 15°-45°. The air outlet of the inner fan 101 is guided by the slope to form a closed ring airflow circulation along the upper and lower inner walls of the cavity, so that the temperature deviation of each area of ​​the cavity is ≤±2℃ and the humidity deviation is ≤±5%RH, ensuring that the vulcanized fiber is heated and moistened evenly.

[0020] In this embodiment, the outer frame 201 is spaced apart from the inner walls of the intermediate aging treatment chamber 1 on both sides, and the outer frame 201 is spaced 50-100mm apart from the inner walls of the intermediate aging treatment chamber 1, forming a side airflow channel. This, combined with the annular circulating airflow, achieves uniform airflow distribution throughout the cavity, improves the consistency of air temperature and humidity inside the intermediate aging treatment chamber 1, and effectively eliminates the regional temperature difference and humidity gradient problems of traditional devices. The conveyor chain 2 has a guide slope 102 and a heating module 103 at both the top and bottom. The humidifying spray pipe 104 is located above the conveyor chain 2. The heating module 103 and the humidifying spray pipe 104 respectively regulate the temperature and humidity.

[0021] In this second embodiment, based on the first embodiment, the upper exhaust pipe 105 is connected to a one-way valve or a solenoid valve for opening and closing control. When the pump connected to the upper exhaust pipe 105 is not started, the upper exhaust pipe 105 is kept closed by the one-way valve or the solenoid valve to reduce the loss of hot air inside the intermediate aging treatment chamber 1 along the upper exhaust pipe 105.

[0022] The working principle of this embodiment: The conveyor chain 2 transports the vulcanized fibers; the heating module 103 and the humidifying spray pipe 104 regulate the temperature and humidity, respectively; the intermediate aging treatment chamber 1 is equipped with temperature and humidity sensors to detect temperature and humidity; through the symmetrical layout of the internal fan 101 and the synergistic effect of the guide slope 102, a closed-loop circular airflow is constructed around the conveyor chain 2 within the intermediate aging treatment chamber 1, achieving seamless airflow within the chamber, accelerating the airflow inside the chamber, and improving the consistency of temperature and humidity within the chamber. Effectively eliminates the regional temperature difference and humidity gradient problem of traditional devices, so that the temperature deviation of each area in the box is controlled within ±2℃ and the humidity deviation is ≤±5%RH, ensuring that the uniformity of heat and moisture of sulfurized fiber during transportation is improved, avoiding excessive aging (such as embrittlement) or insufficient aging (such as performance failure) of some areas due to uneven heat and moisture during transportation of sulfurized fiber in the conveying chain (2). The dispersion of key indicators of sulfurized fiber (such as tensile strength and corrosion resistance) is reduced from 15% to 20% of traditional devices to within 5%, and the product qualification rate is increased to more than 95%, significantly reducing quality risks. The conveyor chain 2 continuously transports the vulcanized fibers into the intermediate aging treatment chamber 1 for aging, forming an integrated continuous process of "feeding-aging-discharging". This replaces the manual feeding and downtime waiting mode of the traditional intermittent aging device. The vulcanized fibers can complete the continuous aging process without intermediate manual intervention, further improving processing efficiency. The annular airflow circulation design reduces the energy consumption of repeated heating / humidification in local high-temperature or low-temperature areas. Combined with the flow-gathering effect of the guide slope 102, the heat loss inside the chamber is reduced by 15% to 20%. The operating power of the heating module 103 and the spray volume of the humidification nozzle 104 can be dynamically matched with actual needs, reducing the overall energy consumption by 10% to 15%. At the same time, due to the improved performance stability, the cost of subsequent screening and rework is reduced by more than 30%, significantly improving the economic efficiency of production. This not only solves the performance dispersion problem of the traditional aging device, but also breaks through the efficiency bottleneck of intermittent production, providing core equipment support for the continuous and high-quality production of vulcanized fibers.
