Description

Technical Field

[0001] This invention relates to the field of spinning tube cleaning technology, specifically to an automatic cleaning device and method for horizontal spinning tubes of viscose filaments. Background Technology

[0002] Viscose filament spinning tubes are slender tubular parts made of quartz glass. In viscose filament spinning production, viscose filaments are extruded from the spinneret orifices and flow into the spinning tube along with the spinning bath. The viscose filaments undergo diffusion, neutralization, coagulation, and decomposition reactions with the unused fresh bath within the spinning tube. The spinning bath mainly consists of a mixture of sulfuric acid, zinc sulfate, and sodium sulfate. During the reaction with the viscose filaments, various inorganic salts are precipitated. These inorganic salts easily deposit and adhere to the inner wall of the spinning tube, forming scale. Over time, this causes the inner diameter of the spinning tube to decrease, reducing the volume of fresh bath and thus affecting the saturation of the reaction within the spinning tube. Therefore, a high degree of cleanliness is required for the inner wall of the spinning tube. The cleanliness of the spinning tube is a key factor affecting the uniformity of subsequent dyeing, spinnability, constant core-sheath ratio of single fibers, and porosity.

[0003] Traditional spinning tube cleaning processes involve first soaking the tubes in a concentrated alkaline solution, then manually rinsing each tube repeatedly with clean water until the cleaning standard is met. During this manual cleaning process, workers are frequently exposed to concentrated alkali, posing significant safety risks. Furthermore, manual cleaning of each tube is inefficient, and continuous rinsing results in substantial water waste. To achieve continuous production, improve efficiency, reduce manpower, save energy, and improve the working environment for employees, a horizontal automatic cleaning device and method for viscose filament spinning tubes has been developed and designed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide an automatic cleaning equipment and method for horizontal spinning tubes of viscose filaments. The equipment mainly consists of a feeding area, a soaking area, a cleaning area, a water blowing and drying area, and a manual inspection area. The equipment can meet the cleaning requirements of spinning tubes and ensure the automatic and continuous operation of the spinning tubes on the cleaning line. The spinning tubes that are finally unloaded and packaged meet the cleaning requirements of spinning tubes, which can effectively solve the problems in the background art.

Each zone is connected in series by the stainless steel conveyor belt 12. The main frame 28 of the cleaning device is welded from 304 stainless steel profiles, and the stainless steel conveyor belt 12 is made of 316 stainless steel mesh conveyor belt. The various components of the cleaning device are fixed to their respective main frames 28, with the specific fixing positions determined according to the actual location. The cleaning equipment is designed with a fully sealed enclosure, and both the alkali-passing zone 2 and the cleaning zone operate under negative pressure to prevent the leakage of harmful gases and pollution to the working environment, ensuring the health of employees. The stainless steel conveyor belt 12 is equipped with supports 35 for supporting the spinning tube 27, with the supports 35 evenly spaced. The alkali-passing zone 2, alkali-blowing zone 3, cleaning zone, and water-blowing and drying zone 7 are each equipped with a clamping device, which includes a positive and negative screw 18, a lower clamping plate 20, and an upper clamping plate 21. The lower clamping plate 20 and the upper clamping plate 21 are fixedly connected to the nuts on the positive and negative screw 18, and the positive and negative screw 18 can drive the lower clamping plate 20 and the upper clamping plate 21 to clamp one end of the spinning tube 27. For clamping or loosening, silicone pads 33 are respectively provided on the corresponding surfaces of the lower clamping plate 20 and the upper clamping plate 21. Clamping grooves 36 are provided on the surface of the silicone pads 33. The clamping grooves 36 are used to hold the spinning tube 27 tightly. The silicone pads 33 play a role in protecting the spinning tube 27 and preventing damage to the spinning tube 27 due to hard contact. The alkali-passing zone 2 is equipped with a alkali-soaking tank 13. The stainless steel conveyor belt 12 of the alkali-passing zone 2 is located in the alkali-soaking tank 13. The alkali-soaking tank 13 of the alkali-passing zone 2 adopts a circulating filtration and periodic liquid replenishment method to refine the use of concentrated alkali, improve the utilization rate and reduce waste liquid discharge pollution. The alkali-soaking tank 13 of the alkali-passing zone 2 is required to achieve automatic operation through a matching circulating water pump 22. Alkali supply circulation; the alkali soaking tank 13 is required to be resistant to strong acids and alkalis and to be well sealed. At the same time, the alkali passing zone is required to be equipped with sampling ports and liquid replenishment ports for detecting and adjusting the alkali concentration. The alkali soaking tank 13 is required to be made of rigid PVC material with a thickness of not less than 8mm. The alkali passing zone 2, the alkali blowing zone 3, the washing zone, and the water blowing and drying zone 7 are each horizontally equipped with telescopic nozzle assemblies.

The telescopic nozzle 32 corresponds one-to-one with the opening of the spinning tube 27. The nozzle telescopic cylinder 14 is connected to the telescopic nozzle 32 through the connecting rod 30. The nozzle telescopic cylinder 14 can drive the telescopic nozzle 32 to move as a whole along the axial direction of the spinning tube 27.

[0026] The cleaning area includes a rough cleaning area 4, a semi-fine cleaning area 5, and a fine cleaning area 6. Below the stainless steel conveyor belt 12 are fine cleaning recovery boxes 9, semi-fine cleaning recovery boxes 10, rough cleaning recovery boxes 11, and a alkali soaking tank 13. Each of the fine cleaning recovery boxes 9, semi-fine cleaning recovery boxes 10, rough cleaning recovery boxes 11, and alkali soaking tank 13 is equipped with a circulating water pump 22. The circulating water pump 22 is connected to the telescopic nozzle 32 through a metal hose 31. The cleaning area is subdivided into rough cleaning, semi-fine cleaning, and fine cleaning. The cleaning water in each area is recycled, filtered, and reused, realizing the graded use of cleaning water and reducing water consumption.

[0027] The alkali blowing zone 3 and the water blowing and drying zone 7 are located above the stainless steel conveyor belt 12 and are equipped with high-pressure blowers 37. The high-pressure blowers 37 are connected to high-pressure air knives through pipes to remove residual alkali from the surface of the spinning tube 27. The coarse washing zone 4, the semi-fine washing zone 5, and the fine washing zone 6 are located above the stainless steel conveyor belt 12 and are equipped with high-pressure spray pipes 38. The high-pressure spray pipes 38 spray high-pressure water to remove foreign objects and impurities from the outer surface of the spinning tube 27. The high-pressure blowers 37 and the high-pressure spray pipes 38 clean the outer surface of the spinning tube 27. The cleaning mechanism for this part is a conventional mechanism and will not be described in detail here. The alkali blowing zone 3 removes residual alkali from the spinning tube 27 in a timely manner to prevent the alkali from being carried into the cleaning zone, increasing the cleaning burden, and causing the cleaning wastewater to have a high alkali content.

[0028] The positive and negative lead screw 18 is mounted on the main frame 28 of the cleaning equipment through the bearing seat 17. One end of the positive and negative lead screw 18 is provided with a gear 16, which meshes with the rack 19. A single double-headed cylinder reciprocates to drive the gear 16 and the rack 19 to move back and forth, thereby driving the positive and negative lead screw 18 to rotate in both directions to complete the clamping and loosening actions.

[0029] The connecting rod 30 is provided with joints 29 at both ends. The connecting rod 30 is slidably connected to the guide rail 34 through the joints 29. One joint 29 is connected to the telescopic shaft of the nozzle telescopic cylinder 14, and the other joint 29 is connected to the telescopic nozzle 32. The center distance of the telescopic nozzles 32 in each zone is guaranteed to correspond one-to-one with the center distance of the spinning tube 27 on the support foot 35 of the stainless steel conveyor belt 12.

[0030] Both the telescopic nozzle 32 and the support foot 35 are made of silicone.

[0033] S1: The transport box containing the dirty spinning tubes 27 is manually sent to the loading area 1; the dirty spinning tubes 27 are taken out from the dirty transport box and arranged one by one on the stainless steel conveyor belt 12 with support feet 35, and the spinning tubes 27 in the loading area 1 are aligned axially.

[0034] S2: The stainless steel conveyor belt 12 sends the dirty spinning tube 27 from the feeding area 1 into the alkali-passing area 2. The alkali solution in the alkali-soaking tank 13 completely submerges the dirty spinning tube 27. The stainless steel conveyor belt 12 pauses for 10-25 seconds.

[0035] S3: When S2 pauses, the positive and negative screws 18 of the clamping device drive the upper clamping plate 21 and the lower clamping plate 20 to clamp and limit the spinning tube 27. The nozzle telescopic cylinder 14 drives the telescopic nozzle 32 to move horizontally along the axis of the spinning tube 27 and connect with the inner hole of the spinning tube 27 in the alkali tank 13. The circulating water pump 22 in the alkali tank 13 starts, so that the alkali solution in the alkali tank 13 circulates continuously from the telescopic nozzle 32 in the inner hole of the spinning tube 27. After running for 10-20 seconds, the circulating water pump 22 in the alkali tank 13 is turned off, and the telescopic nozzle 32 is reset under the action of the nozzle telescopic cylinder 14. The clamping device is reset.

[0036] S4: The stainless steel conveyor belt 12 drives the spinning tube 27 out of the alkali-passing zone 2 and into the alkali blowing zone 3;

[0037] S5: The high-pressure blower 37 on the alkali blowing zone 3 removes the residual alkali solution from the surface of the spinning tube 27. At the same time, the spinning tube 27 pauses on the stainless steel conveyor belt 12 for 10-25 seconds. The clamping device of the alkali blowing zone 3 first clamps and limits the spinning tube 27. The telescopic nozzle 32 of the alkali blowing zone 3 moves horizontally along the axial direction of the spinning tube 27 and connects with the inner hole of the spinning tube 27 on the stainless steel conveyor belt 12. The compressed air valve of the telescopic nozzle 32 opens, and the airflow blows out the residual alkali solution from the inner wall of the spinning tube 27. After running for 10-20 seconds, the compressed air valve closes, the telescopic nozzle 32 resets, the clamping device resets, and the stainless steel conveyor belt 12 drives the spinning tube 27 out of the alkali blowing zone 3 and into the cleaning zone.

[0038] S6: The spinning tube 27 enters the cleaning zone along the stainless steel conveyor belt 12. The high-pressure spray pipe 38 removes foreign objects and impurities from the outer surface of the spinning tube 27. At the same time, the spinning tube 27 pauses on the stainless steel conveyor belt 12 for 10-25 seconds. During the pause, the clamping device in the cleaning zone clamps and limits the spinning tube 27. The telescopic nozzle 32 in the cleaning zone moves horizontally along the axis of the spinning tube 27 and connects with the inner hole of the spinning tube 27 on the stainless steel conveyor belt 12. The circulating water pump 22 in the cleaning zone starts, so that the cleaning water in the water tank circulates continuously from the telescopic nozzle 32 in the inner hole of the spinning tube 27. After running for 10-20 seconds, the circulating water pump 22 in the cleaning zone is turned off, the telescopic nozzle 32 is reset, the clamping device is reset, and the stainless steel conveyor belt 12 drives the spinning tube 27 out of the cleaning zone and into the water drying zone 7.

[0039] S7: The high-pressure blower 37 on the stainless steel conveyor belt 12 removes the residual cleaning water from the surface of the spinning tube 27. At the same time, the spinning tube 27 pauses on the stainless steel conveyor belt 12 for 10-25 seconds. During the pause, the clamping device in the water drying zone 7 clamps and limits the spinning tube 27. The telescopic nozzle 32 in the water drying zone 7 moves horizontally along the axis of the spinning tube 27 and connects with the inner hole of the spinning tube 27 on the stainless steel conveyor belt 12. The compressed air valve of the telescopic nozzle 32 opens, causing the residual cleaning water on the inner wall of the spinning tube 27 to be blown out. After running for 10-20 seconds, the compressed air valve of the telescopic nozzle 32 closes, the telescopic nozzle 32 resets, the clamping device resets, and the stainless steel conveyor belt 12 drives the spinning tube 27 out of the water drying zone 7 and into the manual inspection zone 8.

[0040] S8: After being dried in the air-drying area 7, the spinning tubes 27 are sent one by one to the inspection table in the manual inspection area 8, where the cleaning quality is inspected by the staff and then packed.

[0041] The cleaning area is divided into three parts: coarse cleaning zone 4, semi-fine cleaning zone 5, and fine cleaning zone 6. Fine cleaning zone 6 uses fresh water, semi-fine cleaning zone 5 uses recycled water from fine cleaning zone 6, and coarse cleaning zone 4 uses recycled water from semi-fine cleaning zone 5. The cleaning area is further subdivided into coarse cleaning, semi-fine cleaning, and fine cleaning, and the cleaning water in each zone is recycled and filtered for reuse, realizing the graded use of cleaning water and reducing water consumption.

[0042] Cleaning medium: tap water or soft water treated by water treatment equipment.

[0043] Cleaning qualification standards: The surface of the spinning tube assembly is dry, free of foreign matter residue, and the assembly is undamaged.

[0044] The control system is parameterized and intelligent, enabling flexible production.
