Description

Technical Field

[0001] This invention relates to the field of sol-gel spinning technology, and more particularly to a pipe cleaning device and method for a continuous feeding system in sol-gel spinning. Background Technology

[0002] Micro- and nanofiber materials are solid linear micro- and nanoscale materials with an aspect ratio greater than 1000:1. Due to their advantages such as high pore volume, low density, low mass ratio, and extremely high specific area, micro- and nanofiber materials have a wide range of applications in many fields such as energy storage, electronics, biotechnology, medicine, textiles, and filtration. The growing interest in micro- and nanofiber materials also indicates that micro- and nanofiber material preparation technology will become one of the leaders of the next industrial revolution.

[0003] There are various techniques for preparing micro / nanofiber materials, including electrospinning, centrifugal spinning, and air-jet spinning. Among these, centrifugal spinning, as a highly efficient technique, boasts advantages such as simple structure, high production efficiency, and low energy consumption, and its application prospects are broad. However, in the large-scale continuous production process of centrifugal spinning, a gel film slowly forms on the inner wall of the feed pipe of the continuous feeding system as the feeding time increases. Once this gel film forms, the feed pipe needs to be replaced to ensure the excellent spinnability of the spinning solution. To save production costs, the replaced feed pipe needs to be cleaned for reuse. However, during the pipe cleaning process, it was found that the gel adhering to the inner wall of the pipe needs to be peeled off by simultaneously cleaning with solvent and rubbing the pipe. Since the inner wall of the pipe is covered with gel, every inch of the entire pipe needs to be rubbed, resulting in a large workload and time-consuming cleaning process. If manual cleaning is used, a large number of cleaning personnel need to be hired, which will significantly increase labor costs.

[0004] In summary, the existing material supply pipelines are cleaned manually, which significantly increases labor costs. Summary of the Invention

[0020] Optionally, the rotating component includes a first rotating rod and a second rotating rod;

[0021] The first rotating rod is located above the second rotating rod. The first rotating rod is connected to the distance adjustment mechanism through the drive mechanism. The distance adjustment mechanism drives the first rotating rod to move up and down reciprocally. A second gap is provided between the first rotating rod and the second rotating rod.

[0022] Optionally, one end of the pipe to be cleaned is connected to the other end of the liquid pump pipe, and the other end of the pipe to be cleaned is placed in the second solvent tank.

[0023] According to a second aspect of the present invention, a method for cleaning the pipeline of a continuous feeding system using sol-gel spinning is provided, comprising:

[0024] Step 1: Connect one end of the pipe to be cleaned to the other end of the pump pipe, and place the pipe to be cleaned in the first and second gaps in sequence. The pump will draw out the solvent in the solvent tank at a preset pumping volume and continuously flush the inside of the pipe to be cleaned. The solvent is clean water, tap water or acidic aqueous solution.

[0025] Step 2: Use the first control panel in the front and back kneading device to control the electric power arm assembly to drive the pressure plate to press and knead the pipe to be cleaned placed in the first spacing on the fixed base plate. The pressing and kneading method of the pipe to be cleaned is constant pressure and / or fluctuating pressure.

The direction of pulling the cleaned pipe is away from the front and rear kneading devices.

[0027] Step 4: Finally, while rubbing back and forth and left and right, the solvent is continuously used to flush the inner wall of the pipe to be cleaned. Under the combined action of the shear stress of rubbing and the tensile stress of solvent flushing, the gel adhering to the inner wall of the pipe to be cleaned is peeled off and flows out of the pipe to be cleaned with the flushing of the solvent, and is discharged into the second solvent tank, thus completing the cleaning of the pipe to be cleaned.

[0031] The first control panel in the front and back kneading device controls the electric power arm assembly to drive the pressure plate to compress the inner diameter of the pipe to be cleaned, which is placed within the first spacing, to a thickness of 0-2mm on the fixed base plate with a preset fluctuating pressure, and kneads the pipe to be cleaned back and forth.

[0032] The present invention discloses a pipe cleaning device and method for a continuous feeding system of sol-gel spinning. By placing a liquid pump assembly inside a solvent tank and connecting the assembly to one end of the pipe to be cleaned, the solvent in the tank is extracted and used to flush the inside of the pipe.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] Reference Figures 1 to 9 This invention provides a cleaning device and method for a continuous feeding system pipeline of sol-gel spinning, which can solve the problem that the existing feeding pipeline cleaning is done manually, thus significantly increasing labor costs.

[0048] The present invention provides a pipeline cleaning device for a continuous feeding system of sol-gel spinning, including a workbench 10, a solvent tank 20, a liquid pump assembly 30, a front and rear kneading device 40 and a traction kneading device 50. The solvent tank 20 is located below the workbench 10, and both ends of the solvent tank 20 extend out of both sides of the workbench 10.

[0049] The liquid pump assembly 30 is placed inside the solvent tank 20, and the liquid pump assembly 30 is connected to one end of the pipe 60 to be cleaned.

[0050] The front and rear kneading device 40 is fixedly installed on the upper surface of one side of the workbench 10, and the front and rear kneading device 40 is located close to the liquid pump assembly 30. The front and rear kneading device 40 clamps the pipe 60 to be cleaned, so as to press and knead the pipe 60 to be cleaned.

[0051] The traction and kneading device 50 is fixedly installed on the upper surface of the other side of the workbench 10, and the traction and kneading device 50 and the front and rear kneading devices 40 are on the same horizontal line. The traction and kneading device 50 clamps the pipe 60 to be cleaned, so as to pull and knead the pipe 60 to be cleaned from side to side.

[0052] The solvent tank 20 contains a large amount of solvent, which can be water, tap water, or an acidic aqueous solution. The acid can be, but is not limited to, hydrochloric acid, acetic acid, phosphoric acid, sulfuric acid, citric acid, acetic acid, formic acid, etc. The water-to-acid ratio ranges from 100:0 to 95:5. From an economic perspective, tap water is sufficient; from a fast and efficient cleaning perspective, an acidic aqueous solution is used.

[0053] This invention provides a pipe cleaning device for a continuous feeding system of sol-gel spinning. A pump assembly 30 is placed inside a solvent tank 20 and connected to one end of the pipe 60 to be cleaned. The pump assembly 30 is used to extract solvent from the solvent tank 20 and flush the inside of the pipe 60. Simultaneously, a front-and-back rubbing device 40 is fixedly mounted on the upper surface of one side of a workbench 10, and a traction rubbing device 50 is fixedly mounted on the upper surface of the other side of the workbench 10. The front-and-back rubbing device 40 and the traction rubbing device 50 clamp the pipe 60 to be cleaned, pressing and rubbing it back and forth, and traction and rubbing it left and right, respectively. This process cleans the pipe while simultaneously traction, achieving automatic cleaning of the pipe 60 and significantly reducing costs. This invention solves the problem of existing manual cleaning of feeding pipes, which significantly increases labor costs.

[0054] Reference Figure 2 and Figure 9 Optionally, it also includes a filter screen 70, which is located below the workbench 10 and is vertically fixed in the middle of the solvent tank 20, dividing the solvent tank 20 into a first solvent tank 21 and a second solvent tank 22. The liquid pump assembly 30 is placed in the first solvent tank 21.

[0055] The first solvent tank 21 is used to store the pipe 60 to be cleaned, the second solvent tank 22 is used to collect the wastewater discharged from the pipe 60 to be cleaned, and the filter screen 70 is used to allow the solvent in the first solvent tank 21 and the second solvent tank 22 to flow, thus saving solvent; at the same time, it prevents the gel discharged from the pipe 60 to be cleaned in the second solvent tank 22 from entering the first solvent tank 21 and clogging the liquid pump assembly 30.

[0056] Reference Figure 1 Optionally, the pump assembly 30 includes a pump 31 and a pump tubing 32.

[0057] The liquid pump 31 is placed in the solvent tank 20. One end of the liquid pump pipe 32 is fixedly connected to the liquid pump 31, and the other end of the liquid pump pipe 32 is connected to one end of the pipe 60 to be cleaned.

[0058] The installation of the liquid pump pipe 32 ensures that the pipe 60 to be cleaned is always flushed with solvent.

[0059] Reference Figures 1 to 5 Optionally, the front and rear kneading device 40 includes a fixed base plate 41, a pressure plate 42, an electric power arm assembly 43, and a first control panel 44;

[0060] A fixed base plate 41 is fixedly mounted on the upper surface of one side of the workbench 10. One end of the electric power arm assembly 43 is fixedly mounted on the upper surface of the fixed base plate 41, and the other end of the electric power arm assembly 43 is fixedly mounted on the pressure plate 42. The pressure plate 42 is located above the fixed base plate 41. A first control panel 44 is mounted on the fixed base plate 41. The first control panel 44 controls the electric power arm assembly 43 to drive the pressure plate 42 to move up and down and back and forth. A first gap is provided between the pressure plate 42 and the fixed base plate 41, and the pipe 60 to be cleaned is set within the first gap.

[0061] Furthermore, the first control panel 44 is installed in two different positions on the fixed base plate 41, as detailed in the reference section. Figures 4 to 5 .

[0062] Based on the viscosity of the gel adhering to the pipe 60 to be cleaned, the first control panel 44 controls the electric power arm assembly 43 to drive the pressure plate 42 to press and rub the pipe 60 to be cleaned within the first spacing using two different pressing and rubbing methods on the fixed base plate 41. The first pressing and rubbing method is constant pressure, with the pressure adjusted according to the inner diameter of the pipe 60 to be cleaned, and the pressure range is 10-100N, ensuring that the spacing between the inner walls of the pipe 60 to be cleaned is stably compressed to about 1mm. This ensures that the solvent can continuously rinse the pipe while it is being rubbed and cleaned. The second pressing and rubbing method is fluctuating pressure, with the pressure fluctuating periodically. When the pressure reaches the minimum value, the spacing between the inner walls of the pipe 60 to be cleaned is compressed to about 2mm. When the pressure reaches the maximum value, the pipe 60 to be cleaned is compacted. This ensures that the pipe 60 to be cleaned is rubbed and cleaned while being rinsed with pulsed solvent. The rinsing force is changed by changing the solution flow rate. The two pressing and rubbing methods can be used alternately, or only one of the rubbing methods can be used.

[0063] Reference Figure 4 Optionally, the electric boom assembly 43 includes a first lever arm 430 and a second lever arm 431;

[0064] One end of the first lever arm 430 is fixedly mounted on the upper surface of the fixed base plate 41, and the other end of the first lever arm 430 is rotatably connected to one end of the second lever arm 431. The other end of the second lever arm 431 is fixedly mounted on the pressure plate 42.

[0065] The rotational connection between the first lever arm 430 and the second lever arm 431 causes the second lever arm 431 to drive the pressure plate 42 to press and rub the pipe 60 to be cleaned within the first gap.

[0066] Reference Figures 6 to 8 Optionally, the traction kneading device 50 includes a circuit box 51, a rotating assembly 52, a distance adjustment mechanism 53, a drive mechanism 54, and a second control panel 55;

[0067] The circuit box 51 is fixedly installed on the upper surface of the other side of the workbench 10. The distance adjustment mechanism 53 and the drive mechanism 54 are both located inside the circuit box 51. The distance adjustment mechanism 53 and the drive mechanism 54 are fixedly connected. The second control panel 55 is installed on the circuit box 51. The second control panel 55 controls the distance adjustment mechanism 53 to drive the drive mechanism 54 to move up and down reciprocally. The output shaft of the drive mechanism 54 is connected to the rotating component 52. The rotating component 52 is located outside the circuit box 51. The rotating component 52 is provided with a second spacing. The pipe 60 to be cleaned is set in the second spacing. The first spacing and the second spacing are located on the same horizontal line.

[0068] Furthermore, the installation location of the second control panel 55 in the circuit box 51 is divided into two types, as detailed below. Figures 6 to 8 .

[0069] The second control panel 55 is used to control the distance adjustment mechanism 53 to adjust the second gap. The second gap can be adjusted according to the inner diameter of the pipe 60 to be cleaned, ensuring that the second gap is slightly smaller than the inner diameter of the pipe 60 to be cleaned. The adjustment range of the second gap is 2-5mm. The rotating component 52 rotates in opposite directions, thereby rubbing the pipe 60 to be cleaned and then pulling the cleaned pipe. The cleaned pipe here refers to the pipe that has been rinsed and cleaned by solvent after rubbing. The pulling direction is away from the front and rear rubbing devices 40.

[0070] Reference Figure 7 Optionally, the rotating assembly 52 includes a first rotating rod 520 and a second rotating rod 521;

[0071] The first rotating rod 520 is located above the second rotating rod 521. The first rotating rod 520 is connected to the distance adjustment mechanism 53 through the drive mechanism 54. The distance adjustment mechanism 53 drives the first rotating rod 520 to move up and down reciprocally. A second gap is provided between the first rotating rod 520 and the second rotating rod 521. The first rotating rod 520 and the second rotating rod 521 rotate towards each other to squeeze and rub the pipe 60 to be cleaned placed within the second gap.

[0072] The distance adjustment mechanism 53 indirectly drives the first rotating rod 520 to move up and down to adjust the second distance. The first rotating rod 520 rotates to the left and the second rotating rod 521 rotates to the right, so that the pipe to be cleaned 60 is rubbed and then pulled away from the direction of the front and rear rubbing device 40.

[0073] Reference Figure 1 Optionally, one end of the pipe 60 to be cleaned is connected to the other end of the liquid pump pipe 32, and the other end of the pipe 60 to be cleaned is placed in the second solvent tank 22.

[0074] The other end of the pipe 60 to be cleaned is placed in the second solvent tank 22, so that the gel washed away by the solvent falls into the second solvent tank 22.

[0075] This invention provides a method for cleaning pipelines in a continuous feeding system of sol-gel spinning, comprising:

[0076] Step 1: Connect one end of the pipe 60 to be cleaned to the other end of the pump pipe 32, and place the pipe 60 to be cleaned in the first and second gaps in sequence. The pump 31 extracts the solvent in the solvent tank 20 at a preset pumping volume and continuously flushes the inside of the pipe 60 to be cleaned. The solvent is clean water, tap water or an acidic aqueous solution.

[0077] Step 2: Using the first control panel 44 in the front and back kneading device 40, control the electric power arm assembly 43 to drive the pressure plate 42 to press and knead the pipe 60 to be cleaned placed within the first spacing on the fixed base plate 41. The pressing and kneading method of the pipe 60 to be cleaned is constant pressure and / or fluctuating pressure.

[0078] Step 3: Using the opposing rotation of the first rotating rod 520 and the second rotating rod 521 in the traction and kneading device 50, the pipe 60 to be cleaned placed in the second spacing is rubbed left and right while being pulled clean. The direction of pulling the cleaned pipe is away from the front and rear kneading devices 40.

[0079] Step 4: Finally, while rubbing back and forth and left and right, the solvent is continuously used to flush the inner wall of the pipe to be cleaned 60. Under the combined action of the shear stress of rubbing and the tensile stress of solvent flushing, the gel adhering to the inner wall of the pipe to be cleaned 60 is peeled off and flows out of the pipe to be cleaned 60 with the flushing of the solvent, and is discharged into the second solvent tank 22, thus completing the cleaning of the pipe to be cleaned 60.

[0080] The pumping capacity of the pump 31 ranges from 50 to 300 ml / min. Constant pressure and / or fluctuating pressure are selected based on the viscosity of the gel adhering to the inner wall of the pipe 60 to be cleaned. Constant pressure and fluctuating pressure can be applied alternately, or either method can be used.

[0081] Optionally, in step two, the first control panel 44 of the back-and-forth kneading device 40 controls the electric power arm assembly 43 to drive the pressure plate 42 to apply constant pressure and knead the pipe 60 to be cleaned, which is placed within the first spacing, on the fixed base plate 41. This includes:

[0082] The first control panel 44 in the front and back kneading device 40 controls the electric power arm assembly 43 to drive the pressure plate 42 to compress the inner diameter of the pipe 60 to be cleaned, which is placed in the first gap, to 1mm thickness on the fixed base plate 41 with a preset constant pressure, and knead the pipe 60 to be cleaned back and forth.

[0083] Step two involves using the first control panel 44 in the front and back kneading device 40 to control the electric power arm assembly 43 to drive the pressure plate 42 to apply pressure and knead the pipe 60 to be cleaned, which is placed within the first spacing, on the fixed base plate 41. This includes:

[0084] The first control panel 44 in the front and back kneading device 40 controls the electric power arm assembly 43 to drive the pressure plate 42 to compress the inner diameter of the pipe 60 to be cleaned, which is placed in the first gap, to 0-2mm thickness on the fixed base plate 41 with a preset fluctuating pressure, and knead the pipe 60 to be cleaned back and forth.

[0085] Principle Explanation: Organosilicones, including ethyl silicate 28, ethyl silicate 32, ethyl silicate 40, and tetramethyl silicate, undergo hydrolysis in acidic aqueous solutions. When the hydrolysis reaction is moderate, the resulting silicon-based solution is a non-Newtonian fluid solution with spinnability, which can be used to prepare nanofiber materials. However, during the textile process, excessive solution buildup on the inner wall of the feeding pipe of the feeding system causes it to lose its spinnability and transform from a dissolved state to a silica gel state, thus affecting the feeding efficiency of the pipe and even causing blockage. To avoid blockage of the pipe by excessively hydrolyzed silicon solution and / or formed silica gel, pipes that have been in use for more than 8 hours need to be disassembled and their inner walls cleaned, rinsed, and rubbed with clean water or an acidic aqueous solution. The purpose of cleaning is that the large amount of solvent accelerates the hydrolysis reaction of the solution that has lost its spinnability on the inner wall of the pipe during the rinsing process. After gelation, it is easier to clean. The flow of solvent can also peel off the gel attached to the inner wall of the pipe and discharge it out of the pipe with the flow of solvent.

[0086] In summary, the present invention provides a pipe cleaning device and method for a continuous feeding system of sol-gel spinning. By placing a liquid pump assembly 30 in a solvent tank 20 and connecting the liquid pump assembly 30 to one end of the pipe 60 to be cleaned, the solvent in the solvent tank 20 is extracted and used to flush the inside of the pipe 60. Simultaneously, a front and rear rubbing device 40 is fixedly installed on the upper surface of one side of the workbench 10, and a traction rubbing device 50 is fixedly installed on the upper surface of the other side of the workbench 10. The front and rear rubbing device 40 and the traction rubbing device 50 clamp the pipe 60 to be cleaned and press and rub it back and forth and pull and rub it left and right respectively. While cleaning the pipe to be cleaned, the already cleaned pipe is pulled, realizing automatic cleaning of the pipe 60 and greatly reducing costs. The present invention solves the problem that the existing cleaning of feeding pipes is done manually, which greatly increases labor costs.
