Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of para-aramid production, especially relates to a para-aramid fiber drying device. BACKGROUND

[0002] Para-aramid is also called para-aramid fiber, and is one of the three high-performance fibers in the world, which is obtained by dry-jet wet spinning of poly-p-phenylene terephthalamide fiber. Para-aramid fiber drying is one of the necessary processes, and the drying effect directly affects the quality of the final product.

[0003] When drying para-aramid fiber, the wet material needs to be transported into the dryer for drying. Generally, the para-aramid wet material is sent into the dryer through a spiral feeding mode. However, after the work is completed, there will be residual wet material on the inner wall of the feeding hopper, which is easy to be caked due to natural air drying, affecting the feeding effect. If the feeding structure is cleaned the next day, it will not be able to process during the cleaning time, resulting in waste of time and inconvenience. SUMMARY

[0004] To solve the above technical problems, the utility model provides the following technical scheme, a para-aramid fiber drying device, characterized by comprising:

[0005] A drying module for drying para-aramid fiber wet material;

[0006] A feeding module, the feeding module comprises a feeding hopper and a spiral feeder, the feeding hopper is fixedly arranged at the upper end of the spiral feeder, and is used for guiding the para-aramid fiber wet material into the spiral feeder, and the output end of the spiral feeder is fixedly connected with the input end of the drying module;

[0007] Wherein, the feeding hopper has a plurality of inner walls, each inner wall is provided with a feeding plate, a plurality of feeding plates form a feeding cavity, the feeding plate has a hanging part, and the feeding plate is detachably connected with the feeding hopper through the hanging part.

[0008] Further, a chamfer is formed at the bottom end of the feeding plate.

[0009] Further, the hanging part is a hanging plate fixedly arranged at the upper end of the feeding plate, the hanging plate is hung at the upper end of the feeding hopper, and the inner contour of the hanging plate matches the upper end cross-sectional profile of the inner wall of the feeding hopper.

[0010] Further, it further comprises:

[0011] A hook structure, the end of the hanging plate has a hook structure;

[0012] Wherein, the fillet of the hook structure and the feeding plate form a socket.

[0013] Furthermore, it also includes:

[0014] A positioning column is fixedly provided on the outside of the feed hopper;

[0015] Positioning groove, a positioning groove is provided on the hanging plate;

[0016] Wherein, when the feed plate is hung on the feed hopper, the positioning column is located in the positioning groove.

[0017] Furthermore, it also includes:

[0018] A fixing nut is formed with a thread on the outer surface of the positioning column, and the fixing nut is spirally arranged on the positioning column and contacts the hanging plate.

[0019] Furthermore, the width of the fixing nut is greater than the spacing between the positioning slots.

[0020] The beneficial effects of the present invention are:

[0021] 1. By setting up a feed plate, the feed plate is detachably connected to the feed hopper through a hanging part, so that when cleaning the agglomerated materials, it will not affect the operation of the machine. The feed plate can be taken out to clean the agglomerated materials. At the same time, when the feed plate is put back, the feed plate can scrape the materials on the inner wall of the feed hopper, making the production efficiency higher.

[0022] 2. By opening the chamfer at the bottom end of the feed plate, when the feed plate is put back into the feed hopper, the chamfer setting has the effect of concentrating the force and optimizing the force distribution, so that the feed plate can better scrape off the wet material attached to the inner wall of the feed hopper, and also makes the movement of the feed plate smoother and reduces wear.

[0023] 3. Since the inner contour of the hanging plate matches the cross-sectional profile of the upper end of the inner wall of the feed hopper, when the feed plate is hung on the feed hopper through the hanging plate, the hanging plate can just fit into the upper end of the inner wall of the feed hopper, making the placement of the feed plate more stable.

[0024] 4. By setting up a hook structure, when preparing to hang the feed plate on the feed hopper, the socket formed between the rounded corner of the hook structure and the feed plate can be inserted toward the upper end of the feed hopper, so that the rounded corner of the hook structure plays a transition role during docking and insertion, making the hanging process of the hanging plate smoother and less prone to jamming. At the same time, the hook structure can also play the role of hanging tools in normal times, making it more practical.

[0025] 5. By setting a positioning column and a positioning groove, the lower end of the positioning groove has an opening, so that when the hanging plate is hung on the feed hopper, the positioning column can enter the positioning groove from the opening at the lower end of the positioning groove, which limits the left and right movement of the hanging plate, thereby positioning the position of the feed plate, preventing the feed plate from moving left and right, and making it more stable.

[0026] 6. By setting a fixing nut, after the positioning column enters the positioning groove, the fixing nut can be screwed into the positioning column, and then the fixing nut can be tightened to fix the hanging plate, thereby fixing the feed plate to prevent the feed plate from moving in the feed hopper due to vibration, thereby improving the stability of use.

[0027] 7. Since the width of the fixing nut is greater than the spacing of the positioning slots, when the fixing nut is not separated from the positioning column, if you want to remove the feed plate, the hook structure will move upward to conflict with the fixing nut, preventing misoperation.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely illustrative and not limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following figures. Therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures. Example 1

[0037] This embodiment provides a para-aramid fiber drying device, comprising:

[0038] A drying module, which is used to dry the wet aramid fiber material;

[0039] A feeding module includes a feeding hopper 3 and a screw feeder 4. The feeding hopper 3 is fixedly arranged at the upper end of the screw feeder 4 and is used to introduce the wet aramid fiber material into the screw feeder 4. The output end of the screw feeder 4 is fixedly connected to the input end of the drying module.

[0040] Among them, the feed hopper 3 has multiple inner walls 5, each inner wall 5 is fitted with a feed plate 6, and several feed plates 6 form a feed cavity. The feed plate 6 has a hanging portion, and the feed plate 6 is detachably connected to the feed hopper 3 through the hanging portion.

[0041] In the present technical solution, the drying module can be a disc dryer, a paddle dryer, or a fluidized bed dryer (the working principles of disc dryers, paddle dryers, and fluidized bed dryers are all prior art and will not be described in detail here). The feeding module is used to introduce the wet aramid fiber material into the drying module for drying. After the wet aramid fiber material is transported to the feed hopper 3 by the upstream system, it is fed into the drying module through the screw feeder 4 (the working principle of the screw feeder 4 is prior art and will not be described in detail here). The drying module then continuously dries the wet aramid fiber material until the wet aramid fiber material reaches the set moisture content and is discharged from the discharge port of the drying module.

[0042] After the wet material enters the feed hopper 3, the feed plate 6 fits against the inner wall 5 of the feed hopper 3, so that the wet material falls into the feed cavity formed by the feed plate 6. If there is any residual wet material in the feed hopper 3, it will remain on the feed plate 6 and agglomerate on the feed plate 6 due to natural drying, but will not agglomerate on the feed hopper 3.

[0043] The feed plate 6 is detachably connected to the feed hopper 3 through a hanging portion. When the machine needs to be started and the agglomerated material in the feed hopper 3 needs to be cleaned, it is only necessary to take out the feed plate 6 and clean the feed plate 6. At this time, the feed hopper 3 is protected by the feed plate 6 in advance, so that the inner wall 5 of the feed hopper 3 will not have agglomerated materials. While cleaning the feed plate 6, the inner wall 5 of the feed hopper 3 does not have agglomerated materials, so it can play a normal feeding effect, so that the operation of the machine will not be affected while cleaning the feed plate 6.

[0044] After the agglomerated material on the feed plate 6 is cleaned, the bottom end of the feed plate 6 can be inserted into the feed hopper 3 in contact with the inner wall 5 of the feed hopper 3. During the insertion process, the bottom end of the feed plate 6 will scrape off the material attached to the inner wall 5 of the feed hopper 3. Then, after the insertion of the feed plate 6 is completed, it is hung on the feed hopper 3 through the hanging part and is re-fitted with the inner wall 5 of the feed hopper 3 to continue feeding. At this time, the feed plate 6 covers the inner wall 5 of the feed hopper 3, so that the wet material will not contact the inner wall 5 of the feed hopper 3.

[0045] Through this structural design, a feed plate 6 is set up, and the feed plate 6 is detachably connected to the feed hopper 3 through a hanging part, so that when cleaning the agglomerated material, it will not affect the operation of the machine. The feed plate 6 can be taken out to clean the agglomerated material. At the same time, in the process of putting the feed plate 6 back, the feed plate 6 can scrape the material on the inner wall 5 of the feed hopper 3, so that the production efficiency is higher.

[0047] Furthermore, a chamfer 8 is provided at the bottom end of the feed plate 6 .

[0048] Through this structural design, by opening the chamfer 8 at the bottom end of the feed plate 6, when the feed plate 6 is put back into the feed hopper 3, the setting of the chamfer 8 has the effect of concentrating force and optimizing the force distribution, so that the feed plate 6 can better scrape off the wet material attached to the inner wall 5 of the feed hopper 3, and also makes the movement of the feed plate 6 smoother, reducing wear.

[0051] Through this structural design, since the inner contour of the hanging plate 9 matches the cross-sectional profile of the upper end of the inner wall 5 of the feed hopper 3, when the feed plate 6 is hung on the feed hopper 3 through the hanging plate 9, the hanging plate 9 can just fit into the upper end of the inner wall 5 of the feed hopper 3, making the placement of the feed plate 6 more stable.

[0055] A socket 11 is formed between the rounded corner of the hook structure 10 and the feed plate 6 .

[0056] Through this structural design, by setting up the hook structure 10, when preparing to hang the feed plate 6 on the feed hopper 3, the socket 11 formed between the rounded corner of the hook structure 10 and the feed plate 6 can be inserted toward the upper end of the feed hopper 3, so that the rounded corner of the hook structure 10 plays a transition role during docking and insertion, making the hanging process of the hanging plate 9 smoother and less prone to jamming. At the same time, the hook structure 10 can also serve as a hanging tool in normal times, making it more practical. Example 5

[0062] Through this structural design, by setting the positioning column 12 and the positioning groove 13, the lower end of the positioning groove 13 has an opening, so that when the hanging plate 9 is hung on the feed hopper 3, the positioning column 12 can enter the positioning groove 13 from the opening at the lower end of the positioning groove 13, limiting the left and right movement of the hanging plate 9, thereby positioning the position of the feed plate 6, preventing the feed plate 6 from moving left and right, and improving stability.
