Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of drying equipment, and particularly relates to a drying device for fiber production and a drying method. BACKGROUND

[0002] In the fiber production and processing process, drying is a key link for determining the quality of fiber finished products, production efficiency and energy consumption, and the core requirement is to realize uniform drying of fibers, reduce energy consumption and ensure production continuity. However, the mainstream fiber drying equipment in the current market still has the following shortcomings in actual application:

[0003] The traditional drying equipment adopts a single air duct or a simple diffusion type hot air supply structure, and the hot air is prone to local aggregation or uneven diffusion in the drying cavity. On the one hand, the fibers close to the hot air port are prone to local overheating due to excessive concentration of hot air, resulting in discoloration, brittleness and damage to the physical properties (such as breaking strength and elongation) of the fibers; on the other hand, the fibers away from the hot air port or the edge area of the equipment are insufficiently covered by hot air, resulting in the problems of "wet inside and dry outside" or incomplete drying;

[0004] In addition, a large amount of water vapor is generated during the fiber drying process, and if the water vapor cannot be timely and completely discharged, it will accumulate in the drying cavity, resulting in an increase in the relative humidity in the cavity. The high humidity environment not only slows down the evaporation rate of the fiber moisture and prolongs the drying time, but also may cause the dried fibers to reabsorb water vapor, resulting in the phenomenon of "re-humidification", which affects the final dryness.

Figures 1 to 6The shown drying device for fiber production comprises a conveying belt 1, a heat preservation cover 2 and a flow guide device, the conveying belt 1 is used for conveying the fibers to be dried, and the conveying belt 1 is of hollow metal material; the heat preservation cover 2 is covered on the top of the conveying belt 1 and is used for gathering heat, C-shaped flow guide channels 3 are formed on the inner walls of the two sides of the heat preservation cover 2, a hot air blower 4 and an air extractor 5 are installed on the top of the heat preservation cover 2 from front to back; the flow guide device is arranged inside the heat preservation cover 2 and is used for guiding the air generated by the hot air blower 4, the flow guide device comprises flow guide plates 6 and flow guide covers 7, the flow guide plates 6 are detachably connected between the inner walls of the two sides of the heat preservation cover 2, and the flow guide plates 6 are gradually inclined upward from front to back, a plurality of strip-shaped through holes 8 are formed in the top of the flow guide plates 6, the length direction of the through holes 8 is parallel to the front side of the heat preservation cover 2, a blocking strip 9 matching the length of the through holes 8 is fixedly connected to the front side position of the bottom of the through holes 8, and the bottom edge of the blocking strip 9 is inclined backward, the number of the flow guide covers 7 is two, the two flow guide covers 7 are connected to the bottom end outlet positions of the two flow guide channels 3 respectively, and the top end of the flow guide cover 7 is inserted into the inner side of the conveying belt 1, the heat preservation cover 2 is designed in U shape, the heat preservation cover 2 is fixedly connected to a base 13, and the inner walls of the two sides of the heat preservation cover 2 are filled with heat preservation materials, and the top end openings of the flow guide channels 3 on the two sides of the heat preservation cover 2 are completely located in the top region of the flow guide plates 6;

[0036] The sum of the opening widths of the two flow guide covers 7 matches the width of the conveying belt 1, a plurality of flow uniformizing strips 10 are fixedly connected in parallel between the front and back inner walls of the top end openings of the flow guide covers 7, the length of the flow uniformizing strips 10 matches the length of the blowing area of the hot air blower 4, a plurality of partition pieces 11 are fixedly connected in parallel between the top and bottom inner walls of the bottom end openings of the flow guide covers 7, the distribution density of the plurality of partition pieces 11 gradually decreases from front to back, and the side of the partition pieces 11 close to the conveying belt 1 is inclined backward;

[0037] The drying device for fiber production further comprises a mounting frame 12 for mounting the conveying belt 1 and the base 13, the number of the mounting frames 12 is two, the two mounting frames 12 are symmetrically mounted on the two sides of the conveying belt 1, the mounting frame 12 is fixedly mounted on the top of the base 13, and the front side of the conveying belt 1 is further provided with a feeding assembly;

[0038] When the fibers are dried, as the fibers are placed on the conveyor belt 1, the high-temperature airflow generated by the air heater 4 is partially blown directly on the top surface of the fibers on the conveyor belt 1 through the through holes 8 on the guide plate 6, and the other part can enter the C-shaped guide channel 3 on both sides of the heat preservation cover 2 under the block of the guide plate 6. The C-shaped structure can prolong the residence time of the hot air in the heat preservation cover 2 and reduce the heat loss in the transmission process. Then, the hot air is accurately guided to the top inside of the conveyor belt 1 through the guide cover 7. Since the conveyor belt 1 is made of hollow metal material, the hot air can penetrate the conveyor belt 1 to act on the bottom of the fibers to be dried, and then cooperate with the hot air directly acting on the surface of the fibers through the through holes 8, so as to realize more comprehensive and three-dimensional drying effect of the fibers. And because the uniform flow bar 10 is arranged in the top opening of the guide cover 7, when the hot air blows out from the top of the guide cover 7, the uniform flow bar 10 can further comb the hot air into a uniform airflow layer, so as to ensure that the hot air can fully cover the width direction of the conveyor belt 1, and avoid the situation that the local fibers are not completely dried;

[0039] In addition, by arranging the separation piece 11 with gradually decreasing density from front to back in the bottom opening of the guide cover 7, the function is to adapt to the drying process of the fibers on the conveyor belt 1. Since the water content of the fibers is high when they just enter the drying area, more intensive hot air is needed for rapid dehydration, and as the drying advances, the water content of the fibers decreases, and the hot air density can be appropriately reduced to save energy. This kind of dynamic adaptation of hot air supply mode not only ensures the drying effect, but also realizes the reasonable use of energy;

[0040] In addition, the combination of the inclined guide plate 6, the through hole 8 and the blocking bar 9 forms an efficient water vapor discharge path. The evaporated water vapor rises under the action of the hot airflow, and when it meets the inclined guide plate 6, the water vapor can flow to the area of the air extractor 5 along the inclined surface at the bottom of the guide plate 6 under the guidance of the guide plate 6. In the process of water vapor flowing to the air extractor 5, the presence of the blocking bar 9 can prevent the water vapor from flowing to the top area of the guide plate 6 through the through hole 8, so as to ensure that the water vapor is quickly extracted by the air extractor 5, avoid the accumulation of water vapor in the heat preservation cover 2 affecting the drying efficiency, and ensure that the dryness of the dried fibers meets the standard;

[0041] The present application builds an efficient hot air circulation system through the unique design of the guide channel 3 and the guide device, which fundamentally solves the problems of uneven distribution of hot air and low heat utilization rate of traditional drying equipment.

[0042] For example, Figure 1 And Figure 3As shown, the feeding assembly comprises a portal frame 14, an electric sliding block 15 and a feeding machine 16, the portal frame 14 is fixedly connected to the base 13, the electric sliding block 15 is horizontally slidably installed on one side of the portal frame 14 close to the conveying belt 1, the feeding machine 16 is installed on the electric sliding block 15, and the feeding machine 16 can move back and forth in the horizontal direction under the driving of the electric sliding block 15, a discharge pipe 17 is installed on the feeding machine 16, and the bottom end of the discharge pipe 17 is close to the top of the conveying belt 1;

[0043] The feeding assembly of the present application realizes the automation and precision of fiber feeding, greatly reduces the labor intensity, the feeding machine 16 is installed on the electric sliding block 15, the electric sliding block 15 can slide horizontally along the portal frame 14, driving the feeding machine 16 to move back and forth in the width direction of the conveying belt 1, so that the fiber is evenly laid on the conveying belt 1 through the discharge pipe 17, the sliding speed of the electric sliding block 15 and the discharge rate of the feeding machine 16 can be adjusted according to the type, water content and drying requirements of the fiber, to ensure that the laying thickness of the fiber on the conveying belt 1 is uniform and consistent, and the drying efficiency is ensured;

[0044] In addition, automatic feeding can also reduce the direct contact between workers and fibers, reduce the risk of fiber pollution, ensure the production quality of fibers, and also improve the feeding efficiency, adapt to the demand of large-scale fiber production.

[0045] As shown in Figure 2 and Figure 3 As shown, a plurality of vibration rollers 18 are arranged between the top ends of the two fairings 7, the plurality of vibration rollers 18 are in a uniform horizontal distribution state, the two ends of the vibration roller 18 are rotatably connected with a support rod 19, the support rod 19 is fixedly connected with the mounting frame 12 opposite to the bottom thereof, the top of the vibration roller 18 is in close contact with the inner top of the conveying belt 1, and one end of the vibration roller 18 is connected with a vibrator 20.

[0046] In the conventional drying equipment, the fiber is prone to close stacking, making it difficult for the internal moisture to evaporate, and the phenomenon of "outer dry and inner wet" occurs, the present application sets vibration rollers 18 between the top ends of the two fairings 7, in the process of conveying the fiber by the conveying belt 1, the vibration roller 18 can produce high-frequency micro-vibration under the driving of the vibrator 20, the vibration is transmitted to the fiber on the top of the conveying belt 1, thereby breaking the adhesion between the fibers, making the originally close-stacked fibers loose, increasing the contact area of the fibers and the hot air, at the same time, the vibration can also promote the migration of the internal moisture of the fiber, accelerate the evaporation rate of the moisture, and improve the uniformity of drying.

[0047] As shown in Figure 3 and Figure 6As shown, the bottom of the conveying belt 1 is provided with a cleaning plate 21 matching the width of the conveying belt 1, the bottom edge of the cleaning plate 21 is hinged on the base 13, and the top of the cleaning plate 21 is comb-shaped, a plurality of springs 22 are fixedly connected between the front side of the cleaning plate 21 and the base 13, and the top of the cleaning plate 21 can be kept in close contact with the bottom of the conveying belt 1 under the pushing force of the springs 22;

[0048] During long-term operation of the conveying belt 1, fiber debris is easily left in the hollow structure, and if not cleaned in time, the hollow holes will be blocked, affecting the penetration effect of hot air, and even causing the fiber to jam during conveying. The cleaning plate 21 provided at the bottom of the conveying belt 1 perfectly solves this maintenance problem. The top of the cleaning plate 21 is comb-shaped and always keeps in close contact with the bottom of the conveying belt 1 under the pushing force of the springs 22. When the conveying belt 1 is running, the comb-shaped structure can enter the hollow holes of the conveying belt 1 and scrape off the residual fiber debris, ensuring the ventilation effect of the conveying belt 1. In addition, during the cleaning process of the conveying belt 1 by the cleaning plate 21, since the cleaning plate 21 is attached to the bottom of the conveying belt 1 by the elastic force of the springs 22, the cleaning plate 21 can slightly deflect according to the vibration and running state of the conveying belt 1, ensuring the cleaning effect while avoiding excessive wear of the conveying belt 1. This automatic cleaning method does not require frequent manual intervention, reduces equipment maintenance costs, and ensures the long-term smooth operation of the conveying belt 1.

[0049] As shown in Figure 2 and Figure 3 The top of the two mounting frames 12 is horizontally fixedly connected with a U-shaped blocking frame 23, the top and bottom of the blocking frame 23 are close to the top inner wall of the heat preservation cover 2 and the top of the conveying belt 1 respectively, the opening of the blocking frame 23 faces backward, and the inner opening width of the blocking frame 23 matches the width of the conveying belt 1.

[0050] By providing the blocking frame 23, the blocking frame 23 can prevent the fiber on the conveying belt 1 from deviating to both sides due to vibration or hot air impact during the operation of the conveying belt 1, ensuring that the fiber is always within the drying area and avoiding incomplete drying or waste caused by fiber deviation;

[0051] On the other hand, the blocking frame 23 limits the fiber within a specific area, reduces the diffusion of hot air outside the area, makes the heat more concentrated on the fiber, further improves the heat utilization rate, and shortens the drying time. The top and bottom of the blocking frame 23 are close to the top inner wall of the heat preservation cover 2 and the top of the conveying belt 1 respectively, forming a relatively closed drying space, reducing heat loss, and preventing external cold air from entering the heat preservation cover 2 and affecting the stability of the drying temperature.

[0052] The present application also provides a fiber drying method, comprising the following steps:

[0053] Step one: the fibers to be dried are evenly laid on the conveying belt 1 by the feeding machine 16;

[0054] Step two: start the hot air machine 4, the air extractor 5 and the conveying belt 1, so that the hot air generated by the hot air machine 4 can be blown on the inner top of the conveying belt 1 under the guidance of the flow channel 3 and the flow cover 7, thereby performing the drying operation on the fibers from bottom to top;

[0055] Step three: during the process of blowing the wind at the top end of the flow cover 7 to dry the fibers, the vibrating roller 18 can be driven by the vibrator 20 to vibrate the conveying belt 1 and the fibers on the top thereof, so that the fibers become more loose and the contact efficiency of the fibers and the hot air stream is improved;

[0056] Step four: the evaporated water vapor can enter the area where the air extractor 5 is located under the guidance of the flow plate 6, and finally be extracted by the air extractor 5;

[0057] Step five: the dried fibers can be conveyed to the designated position for collection from the rear side of the conveying belt 1 under the driving of the conveying belt 1.

[0058] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit it.
