Description

TECHNICAL FIELD

[0001] The utility model relates to a drying assembly and drying device suitable for continuous spinning, and particularly relates to a drying device used in the production of viscose fibers, and belongs to the technical field of textile machinery. BACKGROUND

[0002] It is found through research that in the production process of viscose fibers, the strength and elongation of viscose fibers will not decrease with the decrease of drying temperature, and when the drying temperature is in the range of 50-100°C, the breaking strength of the fibers will not only not decrease, but also will increase, and the breaking elongation will also increase with the increase of breaking strength; when the drying temperature exceeds 120°C, the breaking strength and breaking elongation of viscose fibers will both obviously decrease, and the speed of decrease will be faster with the increase of temperature. This phenomenon is particularly obvious in the cake with high water content, and even can cause the deterioration of physical and chemical indexes of the fibers. Therefore, it is more beneficial to improve the strength, elongation and boiling water shrinkage of the yarn by reasonably controlling the drying temperature of viscose fibers, and by reducing the moisture content in the heated air as much as possible and prolonging the drying time.

[0003] In order to better control the temperature during the drying of viscose fibers, the production enterprises of viscose fibers usually use the mode of setting a sandwich in the roller through which the heated circulating water passes to dry the viscose fibers (or yarns) wound on the roller, so as to ensure that the temperature of the dried viscose fibers (or yarns) is always kept at the set temperature, thereby effectively avoiding the adverse effects of unsuitable drying temperature on various indexes of viscose fibers (or yarns) or affecting the drying efficiency. In actual production, since the roller for drying is always in a high-speed rotating state when the drying device is drying viscose fibers, if the mass of the roller is too large, the load of the motor will be large, and the power consumption will be greatly increased; therefore, the water circulation heating device is usually arranged outside the roller to reduce the load of the motor. In the prior art, the water supply and drainage in the sandwich of the rotating roller is realized by connecting the hollow shaft penetrating into the roller with the four-joint sleeve, rotating the hollow pipe in the four-joint sleeve, and connecting the hollow pipe with the water circulation heating device outside through the axial connection rotating joint. However, in the actual production process, as shown in Figure 1 the following problems urgently need to be solved:

[0004] (1) The connection between the hollow pipe and the four-joint sleeve and the connection between the hollow pipe and the rotating joint will cause the problem of bearing leakage to the outside due to the hard connection by using a wire joint. The leakage will not only affect the service life of the bearing, but also cause the low-temperature water discharged to leak from the four-joint sleeve to the water inlet pipe, resulting in the problem that the drying temperature cannot be kept constant or reach the set temperature.

[0005] (2) Since the continuous spinning process requires angle transformation for the drying roller, the hollow tube in the prior art is directly connected to the water inlet pipe in the axial direction, which cannot or hardly achieve angle adjustment, affecting the technical effect of the continuous spinning process, and further directly affecting the production efficiency and the quality of the viscose fiber obtained.

[0006] In the prior art, the water vapor drying is adopted in the utility model patent with the publication number CN202869199U (a steam drying roller with siphon type drying roller), and the oil-electric heating drying is adopted in the invention patent with the publication number CN104153020A (a cantilever type oil-electric heating filament drying device), neither of which adopts the circulating water heating drying mode, nor provides a technical solution to solve the water (or liquid) leakage and angle adjustment.

[0045] In use:

[0046] Step 1: Start the external liquid circulation heating device, and make the liquid heated by the liquid circulation heating device enter the liquid circulation passage, so that the temperature of the surface of the roller 1 reaches the set temperature;

[0047] Step 2: Turn on the drive motor of the synchronous pulley 6, so that the synchronous pulley 6 drives the roller 1 to rotate and dry the yarns wound on the roller 1;

[0048] Step 3: After all the yarns that need to be dried are dried, turn off the drive motor and the external liquid circulation heating device.

[0049] When maintenance is needed: first turn off the drive motor and the external liquid circulation heating device, and then perform maintenance after the components are cooled down. If the circulation pipeline needs to be maintained, the external liquid circulation heating device also needs to be removed and the liquid in the circulation pipeline needs to be drained.

[0050] In this embodiment, the drying assembly is arranged as follows:

[0054] In this embodiment, in order to fix the roller 1 on the hollow shaft 2, a bracket or cover plate is provided on the side close to the fixed bearing seat 3 for fixing, and then connected with the shaft wall of the hollow shaft 2 through the bracket or cover plate, so that the roller 1 is fixed on the hollow shaft 2. It is found in actual production that the cover plate is provided on both ends of the roller 1 to close the internal space, which can effectively reduce the heat loss and achieve better constant temperature effect. At the same time, the cover plate at the end of the roller 1 away from the fixed bearing seat 3 is set as a movable cover plate, which is more convenient for maintenance.

[0055] In this embodiment, in order to avoid the relative displacement between the high-speed rotating roller 1 and the hollow shaft 2, causing the second liquid inlet 18 and the third liquid inlet 24 connection (in the roller 1) and the second liquid outlet 19 and the third liquid outlet 24 connection (in the roller 1) to leak, the soft tube 7 is used to connect between the second liquid inlet 18 and the third liquid inlet 24 and between the second liquid outlet 18 and the third liquid outlet 25, so as to avoid the leakage phenomenon in the roller 1.

[0056] Sealing ring 5: used for preventing liquid leakage, set on the shaft surface of the hollow shaft 2, located between the hollow shaft 2 and the fixed bearing seat 3, and respectively forming the first interface 14, the first liquid inlet 16, the first liquid inlet cavity and the first liquid outlet cavity connected with the hollow shaft 2, the fixed bearing seat 3 and the first liquid outlet 17, and the first liquid inlet cavity and the first liquid outlet cavity are arranged in staggered manner.

[0057] In the embodiment, three sealing rings 5 are arranged on the hollow shaft 2, on both sides of the first liquid inlet 16 and the first liquid outlet 17 and between the first liquid inlet 16 and the first liquid outlet 17. The two sealing rings 5 arranged on both sides of the first liquid inlet 16 are in communication with the hollow shaft 2 and the fixed bearing seat 3 to form a first liquid inlet cavity 20 connected with the first interface 14 and the first liquid inlet 16. The two sealing rings 5 arranged on both sides of the first liquid outlet 17 are in communication with the hollow shaft 2 and the fixed bearing seat 3 to form a first liquid outlet cavity connected with the second interface 15 and the first liquid outlet 17. Due to the arrangement of the sealing rings 5, the first liquid inlet cavity and the first liquid outlet cavity are respectively isolated spaces between the hollow shaft 2 and the fixed bearing seat 3, that is, liquid leakage to both sides does not occur, and mutual cross flow does not occur. In practical application, sealing rings can be arranged as needed, as long as the arrangement can prevent liquid leakage in the inlet and outlet channels, which is suitable for the embodiment.

[0058] The fixed bearing seat 3 is arranged between the roller 1 and the synchronous pulley 6, is sleeved on the outer side of the hollow shaft 2, is internally provided with a third bearing for positioning the hollow shaft 2, and is externally provided with the first interface 14 and the second interface 15 for connecting the external liquid circulating heating device, and the first interface 14 and the second interface 15 are arranged in cooperation with the first liquid inlet 16 and the first liquid outlet 17.

[0059] The fixed bearing seat 3 is internally provided with a third bearing for positioning the hollow shaft 2, and the hollow shaft 2 positioned by the third bearing rotates in the fixed bearing seat 3 under the driving of the synchronous pulley 6.

[0060] The first liquid inlet cavity is in a ring structure, is located in a circular annular space between the hollow shaft 2 and the fixed bearing seat 3, is jointly surrounded by the two sealing rings 5 arranged on both sides of the first liquid inlet 16, the hollow shaft 2 and the fixed bearing seat 3, is used for connecting the first interface 14 and the first liquid inlet 16, and the first liquid inlet 16 rotates in the first liquid inlet cavity along with the hollow shaft 2. After the liquid is heated by the external liquid circulating heating device, the liquid enters the liquid channel 13 arranged in the hollow shaft 2 through the first interface 14, the first liquid inlet cavity and the first liquid inlet 16.

[0061] The first liquid outlet cavity is in a ring structure and is arranged in parallel with the first liquid inlet cavity, is located in a circular annular space between the hollow shaft 2 and the fixed bearing seat 3, is jointly surrounded by the sealing rings 5 arranged on both sides of the first liquid outlet 17, the hollow shaft 2 and the fixed bearing seat 3, is used for connecting the second interface 15 and the first liquid outlet 17, and the first liquid outlet 17 rotates in the first liquid outlet cavity along with the hollow shaft 2. After the liquid discharged from the roller 1 is discharged to the external liquid circulating heating device through the first liquid outlet 17, the first liquid inlet cavity and the second interface 15 for re-heating, the liquid enters the next cycle.

[0062] In the embodiment, the first liquid inlet 16 and the first liquid outlet 17 are arranged on the shaft wall (i.e. the circumferential surface) of the hollow shaft 2 and are arranged in a staggered manner (i.e. the first liquid inlet 16 and the first liquid outlet 17 are located on two different radial planes of the hollow shaft 2) since two isolated first liquid inlet and first liquid outlet need to be formed. The second liquid inlet 18 and the second liquid outlet 19 can be arranged on the end of the hollow shaft 2 or on the shaft wall according to the channel structure in the hollow shaft 2, i.e. can be arranged on the end of the hollow shaft 2 or on the shaft wall, as long as the arrangement does not affect the liquid circulation, which is applicable to the embodiment.

[0063] The liquid channel 13 is arranged in the hollow shaft 2 and includes a liquid inlet channel for the liquid to enter the roller 1 and a liquid outlet channel for the liquid in the roller 1 to be discharged, and the first liquid inlet 16 and the second liquid inlet 18 are respectively located at two ends of the liquid inlet channel, and the first liquid outlet 17 and the second liquid outlet 19 are respectively located at two ends of the liquid outlet channel.

[0064] In the embodiment, the liquid channel 13 can be arranged as two channels (i.e. one is a liquid inlet channel and the other is a liquid outlet channel) or as one channel (i.e. the liquid inlet channel and the liquid outlet channel are both used in the same channel) for the liquid to enter and exit, and the liquid circulation heating can be achieved regardless of the arrangement, but the constant temperature and drying effect of the embodiment cannot be effectively guaranteed when only one liquid channel is arranged.

[0065] In the embodiment, the liquid inlet channel and the liquid outlet channel can be arranged in various shapes or structures according to the needs, and in general, two parallel structures or a layered structure of the liquid channel 13 are used; in addition, the liquid channel 13 can be integrally formed with the hollow shaft 2 to make the overall structure of the liquid channel 13 more stable, thereby achieving better transmission effect; the liquid channel 13 in the form of a connecting pipe can also be arranged in the hollow shaft 2 after the hollow shaft 2 is formed, which can also meet the requirements of circulating water supply and drainage. Therefore, any shape or structure of the liquid channel 13 that can meet the requirements of circulating water supply and drainage in the embodiment is applicable to the embodiment.

[0066] In the embodiment, the layered structure means that the liquid inlet channel is arranged inside or outside the liquid outlet channel, and the main function is to keep the water temperature in the channel constant.

[0067] The liquid circulation route in the embodiment is as follows:

[0068] The liquid heated by the external liquid circulation heating device passes through the external liquid circulation heating device, the first interface 14, the first liquid inlet cavity, the first liquid inlet 16, the liquid inlet channel, the second liquid inlet 18, the interlayer 4, the second liquid outlet 19, the liquid outlet channel, the first liquid outlet 17, the first liquid outlet cavity, and the second interface 15 in sequence, is heated again by the external liquid circulation heating device, and then enters the next cycle.

[0069] In actual continuous spinning production, once the drying assembly is started, it is usually in operation, that is, the roller 1 is always rotating, the liquid is always circulating and heated, and the temperature on the roller 1 is always kept constant (the temperature range is between 50°C and 100°C, with the optimal temperature being 60°C), thereby ensuring production efficiency and reducing production costs.

[0070] Furthermore, in order to maintain a constant temperature for the circulating liquid, the liquid channel 13 is configured as a nested structure in this embodiment, including an inlet channel located inside and an outlet channel nested outside. It can also preheat the liquid in the outlet channel, thereby further reducing energy consumption.

[0071] Furthermore, to prevent the heated liquid from maintaining a constant temperature, an insulation layer is also provided on the liquid channel 13. In this embodiment, the insulation layer is fitted over the outside of the liquid outlet channel, thereby achieving a better temperature control effect.

[0072] Example 2:

[0073] like Figure 2 and Figure 3 As shown, this embodiment discloses a drying assembly suitable for continuous spinning, which is an optimized design based on Embodiment 1. The main difference between this embodiment and Embodiment 1 is that it also includes an angle adjustment device and a cooperating adjusting bearing seat 9. The angle adjustment device includes a self-aligning bearing 10 and a universal joint 8. The self-aligning bearing 10 is fixedly installed in the fixed bearing seat 3. One end of the universal joint 8 is sleeved in the self-aligning bearing 10 and connected to the end of the hollow shaft 2. The other end of the universal joint 8 is connected to the synchronous pulley 6 for transmission. The adjusting bearing seat 9 is sleeved on the outside of the hollow shaft 2 and fixed in the fixed bearing seat 3 by at least two length-adjustable set screws. The hollow shaft 2 is rotatably mounted inside the adjusting bearing seat 9. The outer wall of the adjusting bearing seat 9 is provided with a third interface and a fourth interface. The sealing ring 5 is located between the hollow shaft 2 and the adjusting bearing seat 9, and forms a second liquid inlet cavity with the hollow shaft 2 and the adjusting bearing seat 9, which communicates with the third interface 22 and the first liquid inlet 16, and a second liquid outlet cavity with the hollow shaft 2 and the fixed bearing seat 3, which communicates with the fourth interface 23 and the first liquid outlet 17. The second liquid inlet cavity and the second liquid outlet cavity are staggered. The third interface 22 is connected to the external liquid circulation heating device through the first interface 14, and the fourth interface 23 is connected to the external liquid circulation heating device through the second interface 15.

[0074] In this embodiment:

[0075] Self-aligning bearing 10: It is fixedly installed in the fixed bearing seat 3 and sleeved on the outer end of one end of the universal joint 8, so as to support the universal joint 8.

[0076] Universal joint 8: one end is sleeved in the self-aligning bearing 10 and connected with the end of the hollow shaft 2, the other end is drivingly connected with the synchronous pulley 6, and drives the hollow shaft 2 to rotate with the synchronous pulley 6.

[0077] Adjusting bearing seat 9: sleeved outside the hollow shaft 2, and fixed in the fixed bearing seat 3 through at least two length-adjustable top screw bolts, the hollow shaft 2 is rotatably arranged in the adjusting bearing seat 9; the outer wall of the adjusting bearing seat 9 is provided with a third interface 22 and a fourth interface 23, and the third interface 22 is connected with the external liquid circulating heating device through the first interface 14, and the fourth interface 23 is connected with the external liquid circulating heating device through the second interface 15.

[0078] Sealing ring 5: sleeved on the shaft surface of the hollow shaft 2, located between the hollow shaft 2 and the adjusting bearing seat 9, and respectively forming a second liquid inlet cavity 24 communicated with the third interface 22 and the first liquid inlet 16 with the hollow shaft 2 and the adjusting bearing seat 9, and a second liquid outlet cavity 25 communicated with the fourth interface 23 and the first liquid outlet 17 with the hollow shaft 2 and the adjusting bearing seat 9. In this embodiment, three sealing rings 5 are arranged, which are arranged on the hollow shaft 2 on both sides of the first liquid inlet 16 and the first liquid outlet 17 and between the first liquid inlet 16 and the first liquid outlet 17. The two sealing rings 5 arranged on both sides of the first liquid inlet 16 are communicated with the third interface 1 and the first liquid inlet 16 of the second liquid inlet cavity of the hollow shaft 2 and the adjusting bearing seat 9, and the two sealing rings 5 arranged on both sides of the first liquid outlet are communicated with the fourth interface and the first liquid inlet of the first liquid outlet cavity of the hollow shaft 2 and the adjusting bearing seat 9. Since the sealing ring 5 is arranged, the second liquid inlet cavity and the second liquid outlet cavity are respectively isolated spaces between the hollow shaft 3 and the adjusting bearing seat 9, that is, there is no liquid leakage to both sides, and there is no mutual cross flow.

[0079] In this embodiment, since it is necessary to adjust the deflection angle of the roller 1 according to the production process, the adjusting bearing seat 9 is fixed in the fixed bearing seat 3 through two length-adjustable top screw bolts. The length of the two top screw bolts in the fixed bearing seat 3 is adjusted through the cooperation of the two top screw bolts, that is, the position of the adjusting bearing seat 9 in the fixed bearing seat 3 is changed, and the hollow shaft 2 in the adjusting bearing seat 9 is deflected at the same time, so that the roller 1 is deflected with the hollow shaft 2.

[0080] In this embodiment, as shown in Figure 2 and Figure 3 , the two top screw bolts are oppositely arranged along the radial direction of the fixed bearing seat 3, one end of the two top screw bolts is rotatably connected to the fixed bearing seat 3, and the other end of the two top screw bolts abuts against the outer wall of the adjusting bearing seat 9 and fixes the adjusting bearing seat 9 in the fixed bearing seat 3.

[0081] When the two top screw bolts adjust their length in cooperation: in the fixed bearing seat 3, one top screw bolt is elongated, and the other top screw bolt is shortened, so that the adjusting bearing seat 9 deflects in the fixed bearing seat 3 under the joint action of the two top screw bolts and the universal joint 8, and simultaneously drives the hollow shaft 2 fixed therein and the roller 1 thereon to deflect. The length of the top screw bolt should be determined according to actual needs to ensure that the deflection angle of the roller 1 can meet the process needs.

[0082] The second liquid inlet cavity: a ring structure, a circular annular space between the hollow shaft 2 and the fixed bearing seat 3, which is surrounded by the two sealing rings 5 arranged on both sides of the first liquid inlet 16, the hollow shaft 2 and the fixed bearing seat 3, used to connect the third interface 22 and the first liquid inlet 16, and the first liquid inlet 16 rotates with the hollow shaft 2 in the second liquid inlet cavity. After the liquid is heated by the external circulating heating device, it enters the liquid passage 13 arranged in the hollow shaft 2 through the first interface 14, the third interface 22, the second liquid inlet cavity, and the first liquid inlet 16.

[0083] The second liquid outlet cavity: a ring structure, a circular annular space arranged in parallel with the second liquid inlet cavity, located between the hollow shaft 2 and the fixed bearing seat 3, surrounded by the sealing ring 5 arranged on both sides of the first liquid outlet 17, the hollow shaft 2 and the fixed bearing seat 3, used to connect the fourth interface 23 and the first liquid outlet 17, and the first liquid outlet 17 rotates with the hollow shaft 2 in the first liquid outlet cavity. The liquid discharged from the roller 1 is discharged to the external liquid circulating heating device for re-heating after the first liquid outlet 17, the second liquid inlet cavity, the fourth interface 23, and the second interface 15, and enters the next cycle.

[0084] The liquid circulation route in the embodiment is: the liquid heated by the external liquid circulating heating device passes through the external liquid circulating heating device, the first interface 14, the third interface 22, the second liquid inlet cavity, the first liquid inlet 16, the liquid inlet passage, the second liquid inlet 18, the interlayer 4, the second liquid outlet 19, the liquid outlet passage, the first liquid outlet 17, the first liquid outlet cavity, the fourth interface 23, and the second interface 15 in turn, and then returns to the external liquid circulating heating device for re-heating, and enters the next cycle.

[0085] Further, in order to prevent the risk of increasing liquid leakage by setting a connecting pipe between the first interface 14 and the third interface 22 or between the second interface 15 and the fourth interface 23, the first interface 14 and the second interface 15 are arranged to cooperate with the third interface 22 and the fourth interface 23 respectively, and the openings for the connecting pipe of the external liquid circulating heating device are used, so as to ensure the smoothness of the liquid circulation route.

[0086] Further, in order to ensure the stability of the deflection of the roller 1, a first bearing 11 for positioning the hollow shaft 2 is arranged in the adjusting bearing seat 9, and a second bearing 12 for positioning the cardan joint 8 is arranged in the fixed bearing seat 3.

[0087] In the embodiment, the first bearing 11 is arranged in the adjusting bearing seat 9 near the roller 1, and the second bearing 12 is arranged in the fixed bearing seat 3 near the synchronous pulley 6, so as to ensure the stability of the deflection of the roller 1.

[0088] Further, in order to enhance the stability of the deflection of the roller 1 and avoid the phenomenon that the jackscrew slips with the outer wall of the adjusting bearing seat 9, the inner end surface of the jackscrew is arranged as a curved surface matched with the outer wall of the adjusting bearing seat 9. In addition, a groove matched with the jackscrew can also be arranged on the outer wall of the adjusting bearing seat 9, so as to achieve the purpose of enhancing the stability of the deflection of the roller 1. Therefore, as long as the jackscrew or the shape or structure on the adjusting bearing seat 9 can enhance the stability of the deflection of the roller 1, it is applicable to the embodiment.

[0089] The embodiment is an optimization scheme based on the embodiment 1, and the use method is only to adjust the angle, that is, by adjusting the length of the two matched jackscrews, the purpose of adjusting the deflection angle of the roller 1 can be achieved. In actual production, the deflection angle required for the same process or the same fixed process is usually fixed, so it is not necessary to frequently adjust the deflection angle of the roller 1. Therefore, only the angle adjustment is required before use according to the process or the process requirement, and the other use methods are the same as those of the embodiment 1, and thus will not be repeated.

[0093] In the embodiment, the sealing ring 5 is made of rubber material, so that the sealing performance is better. In order to prevent the sealing ring 5 from affecting the hollow shaft 2, a wear-resistant layer is arranged on the surface of the sealing ring 5. The wear-resistant layer can be made of powder or solvent, and can be made of polymer, epoxy resin, silicone material, ceramic or fluorocarbon, as long as the material can achieve the sealing effect of the sealing ring 5 and minimize the influence on the rotation of the hollow shaft 2.
